Background

Sweater is intended to mean knitwear knitted with wool, and in fact "woolen sweater" has now become a generic term for a class of products, namely "knitwear" or "woollen knitwear". The wool knitwear is mainly a fabric woven by using animal hair fibers such as wool, cashmere, rabbit hair and the like as main raw materials to spin yarns, and the like, such as rabbit hair sweaters, snow blue sweaters, cashmere sweater, acrylic sweaters and the like are the large families of 'woolen sweaters'. With the improvement of living standard of substances, the requirements of people on textiles are not limited to the original basic characteristics of warm keeping, comfort and the like, and the requirements on the woolen sweater with special functions of health care, safety and the like are more required, such as flame retardance, antibiosis, mite and moth prevention, ultraviolet ray prevention, poison prevention, electromagnetic wave radiation prevention, magnetic therapy, fragrance, moisture absorption and sweat release, oil and water prevention and the like. At present, the compounding of textile technology is the main trend of the development of international textile technology, and natural fibers are mutually blended, interwoven and combined to obtain new serviceability and functionality. The development of products with multiple purposes, high performance and high added value by adopting a new process, new equipment and a new technology becomes a new development trend of textiles.

In the Chinese invention patent (application number: 2016103291900), the invention discloses a flame-retardant antibacterial environment-friendly woolen sweater which contains flame-retardant aramid fibers, has good high temperature resistance and flame retardance, and is permanently flame-retardant; the natural green chitin fiber and the regenerated bamboo fiber are added, so that the antibacterial deodorant fabric is safe and harmless, is moisture-absorbing and breathable, has the functions of antibiosis and deodorization, skin care and adjuvant therapy of allergic skin, and also has the functions of static resistance and environmental protection; the use amount of wool and cashmere is reduced, the production cost is reduced under the condition of ensuring the performance, the permanent flame retardance and the antibiosis are realized, the standard of green textiles is met, the production flow is greatly shortened because the after finishing is not needed by finishing liquid, a large amount of chemical reagents and toxic gas are avoided, and the production efficiency and the wearing safety performance of the woolen sweater are greatly improved; however, the patent does not consider that if the user belongs to the obese people, the buttons on the woolen sweater are easy to fall off due to overlarge stress in the violent movement, so that the wearer of the woolen sweater cannot keep the state in the movement, the wearing experience of the user is greatly influenced, and the technical scheme is limited.

In view of the above, the method of respectively arranging the magnets on the female buckle and the male buckle of the woolen sweater buckle ensures that the female buckle and the male buckle of the woolen sweater can be tightly buckled even under the extreme environment of fat and violent movement of a wearer, thereby ensuring the wearing experience of the user.

Disclosure of Invention

In order to make up the defects of the prior art and solve the problem that buttons of the existing woolen sweater are easy to fall off when the body of a wearer is fat and the body of the existing woolen sweater is strenuously exercised, the invention provides the flame-retardant antibacterial environment-friendly woolen sweater.

The technical scheme adopted by the invention for solving the technical problems is as follows: the flame-retardant antibacterial environment-friendly woolen sweater comprises a sweater body, sleeves and buckles, wherein the sweater body comprises a left sweater piece and a right sweater piece, and the sleeves are symmetrically arranged on two sides of the sweater body; the clothes buttons comprise male buttons and female buttons, the female buttons are uniformly arranged on the side edge of the left clothes piece from top to bottom, and the male buttons are uniformly arranged on the side edge of the right clothes piece from top to bottom; the surface of the female buckle opposite to the surface of the male buckle is provided with a groove, a first magnet is arranged inside the groove, the surface of the male buckle opposite to the female buckle is provided with a convex block, the convex block is provided with an insertion hole, and a wooden separation blade is arranged inside the insertion hole; a first air bag is arranged inside the right garment piece and close to the upper side of the male buckle, a second air bag is arranged inside the right garment piece and close to the lower side of the male buckle, and the first air bag and the second air bag are communicated with the jack through a first pipeline; a first cavity is arranged in the male buckle, one side of the first cavity is communicated with the jack, and the other side of the first cavity is communicated with the first air bag and the second air bag through a second pipeline; a second magnet and a spring are arranged in the first cavity, one end of the spring is fixedly connected with the second magnet, and the other end of the spring is fixedly connected with the inner wall of one side of the first cavity communicated with the second pipeline; when the male buckle and the female buckle are mutually buckled, the male buckle and the female buckle are tightly buckled and are not easy to fall off due to the action of the first magnet and the second magnet.

When the female buckle and the male buckle start to be buckled, the first magnet of the female buckle is inserted into the jack of the male buckle lug, and gas in the jack is compressed to flow towards the first chamber; however, the flowing gas is blocked by the wooden baffle plate on the way, so that the gas can only flow to the first air bag and the second air bag along the first pipeline; the gas inside the first air bag and the second air bag becomes more, so that the air pressure is increased, and the pressurized gas flows into the first chamber along the second pipeline; the second magnet in the first chamber moves towards the direction close to the first magnet under the action of the inflowing gas, and the spring fixedly connected with the second magnet is stretched; because the wooden separation blade does not have the effect of isolating the magnetic force, the first magnet and the second magnet can attract and attach to each other through the wooden separation blade, so that the female buckle and the male buckle can be tightly fastened and cannot be easily separated.

Preferably, a third pipeline is arranged inside the male buckle, an arc-shaped pressing sheet is arranged in the third pipeline, a double-head pressing block is arranged at one end of the arc-shaped pressing sheet, the other end of the arc-shaped pressing sheet is in contact with a second magnet, the contact surface between the second magnet and the arc-shaped pressing sheet is an inclined edge, and two pressing blocks are arranged at one end, far away from the arc-shaped pressing sheet, of the double-head pressing block; the double-end pressing block can extend out and tightly clamp the female buckle when the male buckle and the female buckle are not stably buckled; when the garment is in work, when the body of a wearer is fat and doing strenuous exercise, the buttons connecting the left garment piece and the right garment piece are subjected to large force, so that the female button and the male button tend to be separated from each other; at the moment, the first magnet on the female buckle is slowly drawn out of the jack due to large stress, so that the air pressure in the jack is low, the air in the first air bag and the air in the second air bag flow to the jack, and meanwhile, the air in the first cavity also flows to the first air bag and the second air bag along the second pipeline respectively; therefore, the second magnet in the first chamber is not acted by gas any more, and moves in the direction away from the first magnet under the tensile force of the spring along with the recovery of the stretched spring; the contact surface of the second magnet and the arc-shaped pressing sheet is an inclined edge, so that the arc-shaped pressing sheet can be pressed when the second magnet moves, and the arc-shaped pressing sheet moves in the third pipeline under the pressing action, so that two pressing blocks of the double-head pressing block arranged at the end part of the arc-shaped pressing sheet can extend out of two openings of the third pipeline and contact with the female buckle, and the friction force applied to the female buckle after the female buckle is separated from the male buckle is increased; therefore, the female buckle is clamped, the male buckle and the female buckle are buckled more stably, and the use of a wearer is facilitated.

Preferably, a group of elastic lugs are uniformly arranged at the end parts of the two pressing blocks, and the elastic lugs can improve the friction force between the pressing blocks and the contact surface of the female buckle; during operation, the compact heap stretches out and contacts with the box from No. three pipelines, and the tip surface that compact heap and box contacted evenly is equipped with elastic convex block, and these elastic convex blocks can increase the roughness of compact heap tip and box contact surface for it is bigger to receive the frictional force from the compact heap when the box is taken out again, so the lock of box and pin thread is more firm.

Preferably, a second cavity is arranged inside each elastic lug, rosin powder is filled in each second cavity, and each second cavity is connected with the outside through a spray hole; when the rosin powder spraying device works, when the pressing block extends out to contact with and tightly clamp the female buckle, the elastic lug at the end part of the pressing block is extruded and deformed, and the second chamber in the elastic lug is also deformed under pressure, so that the rosin powder filled in the second chamber is sprayed out from the spray holes and is dispersed to the surface of the double-head lug, which is in contact with the female buckle; the rosin powder has good physical and chemical properties of viscosity, particularly good pressure sensitivity, quick viscosity and low-temperature viscosity, but poor cohesion, so the rosin powder has the effects of preventing slipping and increasing friction; therefore, when the rosin powder is scattered on the surface of the pressing block contacted with the female buckle, the friction force applied when the female buckle is separated becomes large, and the buckling stability of the female buckle and the male buckle is further enhanced.

Preferably, the inner bags are arranged inside the first air bag and the second air bag, each inner bag is filled with the flame-retardant antibacterial agent and is communicated with the outside through a fourth pipeline, and the flame-retardant antibacterial agent can be sprayed out when each inner bag is pressed, so that the flame-retardant antibacterial agent is mixed into the woolen sweater to prolong the service life of the woolen sweater; when the air bag is in work, when the female buckle is buckled with the male buckle, air in the jacks flows into the first air bag and the second air bag along with the first pipeline, and air pressure in the first air bag and the second air bag is increased; therefore, the inner bags arranged in the first air bag and the second air bag are pressed and spray the flame-retardant antibacterial agent through the fourth pipeline, and the sprayed flame-retardant antibacterial agent can be dispersed in the clothes body and improve the flame-retardant antibacterial capability of the clothes body, so that the service life of the clothes is prolonged.

As an embodiment of the invention, a group of elastic protrusions 333 is uniformly arranged at the end portions of the two pressing blocks 332, and the elastic protrusions 333 can improve the friction force of the contact surface between the double-head pressing block 331 and the female buckle 32; in operation, the pressing block 332 extends out of the third pipeline 317 and contacts with the female buckle 32, the end surface of the pressing block 332 contacting with the female buckle 32 is uniformly provided with elastic lugs 333, and the roughness of the contact surface of the end of the pressing block 332 and the female buckle 32 can be increased by the elastic lugs 333, so that the friction force of the double-head pressing block 331 on the female buckle 32 during extraction is larger, and the buckling of the female buckle 32 and the male buckle 31 is firmer.

As an embodiment of the present invention, a second cavity 334 is disposed inside each elastic bump 333, each second cavity 334 is filled with rosin powder, and each second cavity 334 is connected to the outside through a nozzle 335; in operation, when the pressing block 332 of the double-head pressing block 331 extends out to contact with the female buckle 32 and tightly clamp the female buckle 32, the elastic lug 333 at the end of the pressing block 332 is pressed to deform, and at the same time, the second chamber 334 arranged inside the elastic lug 333 is also pressed to deform, so that the rosin powder filled inside the second chamber 334 is sprayed out from the spray hole 335 and is dispersed to the surface of the pressing block 332 contacting with the female buckle 32; the rosin powder has good physical and chemical properties of viscosity, particularly good pressure sensitivity, quick viscosity and low-temperature viscosity, but poor cohesion, so the rosin powder has the effects of preventing slipping and increasing friction; therefore, when the rosin powder is spread on the surface of the compact block 332 contacting the box 32, the friction force applied when the box 32 is separated becomes large, and the stability of the engagement between the box 32 and the pin 31 is further enhanced.

As an embodiment of the invention, the first air bag 121 and the second air bag 122 are both internally provided with inner bags 125, each inner bag 125 is filled with a flame-retardant antibacterial agent and is communicated with the outside through a fourth pipeline 124, and each inner bag 125 can spray the flame-retardant antibacterial agent when being pressed, so that the flame-retardant antibacterial agent is mixed into the woolen sweater to prolong the service life of the woolen sweater; during operation, when the female buckle 32 is buckled with the male buckle 31, the gas in the insertion hole 312 flows into the first air bag 121 and the second air bag 122 along with the first pipeline 123, and the air pressure in the first air bag 121 and the second air bag 122 is increased; therefore, the inner bags 125 arranged in the first air bag 121 and the second air bag 122 are pressed and spray the flame-retardant antibacterial agent through the fourth pipeline 124, and the sprayed flame-retardant antibacterial agent is dispersed in the clothes body 1 and improves the flame-retardant antibacterial capability of the clothes body 1, so that the service life of the invention is prolonged.

As an embodiment of the invention, the flame-retardant antibacterial materials blended by the clothes body 1 are gradually increased from inside to outside, so that the safety of users is improved; during operation, because the bacterial contamination and the dangerous external world of burning that influence woollen sweater life mainly come from, so make the distribution of the fire-retardant antibacterial material of woollen sweater blending from inside to outside increase gradually to strengthen the utilization ratio to fire-retardant antibacterial material, improve the fire-retardant antibacterial ability of woollen sweater, and then improve the life of woollen sweater.

When the woolen sweater fixing device works, when the female buckle 32 and the male buckle 31 are buckled, the first magnet 322 of the female buckle 32 is inserted into the insertion hole 312 of the convex block 311 of the male buckle 31, gas in the insertion hole 312 flows in a direction close to the first chamber 314 under compression, the flowing gas can only flow to the first air bag 121 and the second air bag 122 along the first pipeline 123 due to the blocking effect of the wooden blocking sheet 313, and the gas in the first air bag 121 and the second air bag 122 is increased to increase the air pressure, so that the inner bags 125 of the first air bag 121 and the second air bag 122 can both spray the filled flame-retardant antibacterial agent, and the service life of the woolen sweater is prolonged; on the other hand, the pressurized gas flows into the first chamber 314 along the second pipe 124, the second magnet 315 inside the first chamber 314 moves under the action of the gas, and the spring 316 is stretched; because the wooden retaining sheet 313 has no effect of isolating magnetic force, the first magnet 322 and the second magnet 315 can attract and attach to each other through the wooden retaining sheet 313, so that the female buckle 32 and the male buckle 31 can be tightly fastened; when the wearer moves violently, the female buckle 32 and the male buckle 31 tend to be separated from each other; at this time, the first magnet 322 on the female buckle 32 is slowly drawn out from the insertion hole 312 due to a large force, so that the air pressure in the insertion hole 312 is reduced, and therefore, the air in the first air bag 121 and the second air bag 122 flows to the insertion hole 312, and meanwhile, the air in the first chamber 314 also flows to the first air bag 121 and the second air bag 122 along the second pipeline 124; the second magnet 315 is no longer acted by gas, and along with the recovery of the stretched spring 316, the second magnet 315 can press the arc-shaped pressing sheet 33 when moving, and at the moment, the arc-shaped pressing sheet 33 is pressed to move in the third pipeline 317, so that the arc-shaped pressing sheet 33 can drive the double-head pressing block 331 to move, and the two pressing blocks 332 at the end part of the double-head pressing block 331 can extend out of the two openings of the third pipeline 317 and contact with the female buckle 32, and because the end parts of the two pressing blocks 332 are uniformly provided with the elastic lugs 333, a second cavity 334 is arranged inside each elastic lug 333, and the filled rosin powder can be sprayed out when the second cavity 334 is pressed, so that the friction force applied to the female buckle 32 to be separated from the male buckle 31 is increased; therefore, the female buckle 32 is clamped, the buckling of the male buckle 31 and the female buckle 32 is more stable, and the use of a wearer is facilitated.
