Technical Field

The invention relates to the technical field of clothes, in particular to a down jacket with detachable sleeve caps and a contractible cap opening stay cord.

Background

The down coat has good warm-keeping performance and wearing comfort, so the down coat is favored by the majority of users in winter. The down jacket comprises a jacket body, sleeves, a hat and the like, wherein one of the places where the down jacket is most contacted with the outside is the sleeves in daily life and work, and the sleeve heads of the sleeves are the places where dirt is most seriously generated. After the down jacket is worn for a period of time, when the sleeves of the down jacket are dirty, other parts of the sleeves, the body, the caps and the like are clean, but the sleeves are generally fixed on the sleeves of the down jacket, so that the whole down jacket needs to be washed, which is very inconvenient. Meanwhile, the dirty sleeve head is easy to deform due to washing, and the original contour and the appearance are lost. In addition, since the sleeve caps are the most easily worn parts of the down jacket, other parts of the sleeve caps are still intact, and the sleeve caps are damaged or deformed, so that the down jacket cannot be worn.

In addition, the mouth of the down jacket generally fixes the hat to the head of a person by tightening the pull cord of the hat, and the existing hat pull cord generally comprises two types, namely an elastic pull cord and a non-elastic pull cord, wherein part of the elastic pull cord can be retracted into the hat when tightening is not needed, but due to the characteristics of the elastic pull cord, the loosening phenomenon is easy to occur after tightening, so that the use of the non-elastic pull cord is more common. Due to the non-telescopic property of the non-elastic pull rope, the user can be influenced by swinging the rope belt in the movement process, or the rope belt is mistakenly dropped into tableware when drinking tea or eating, in addition, due to the non-fixity of the pull rope, the situation that the pull rope on one side is longer and the pull rope on the other side is shorter often occurs, the adjustment is often needed for the user, and unnecessary troubles are brought to the life of people.

Further, the third transmission gear 733 and the second transmission gear 732 of the present embodiment are coaxially disposed and synchronously rotate, the radial dimension of the third transmission gear 733 is greater than twice the radial dimension of the second transmission gear 732, and further, the fourth transmission gear 734 of the present embodiment is in transmission fit with the third transmission gear 733, and the radial dimension of the third transmission gear 733 is greater than twice the radial dimension of the fourth transmission gear 734, so that the third transmission gear 733 rotates one circle, and the fourth transmission gear 734 rotates more than two circles, thereby implementing a two-stage transmission.

The inertia flywheel 740 and the fourth transmission gear 734 are coaxially arranged and synchronously rotate, the radial dimension of the inertia flywheel 740 is larger than twice the radial dimension of the fourth transmission gear 734, the rotation speed of the inertia flywheel 740 is increased by at least four times compared with the primary first transmission gear 731, the inertia flywheel 740 can rotate for multiple circles within a small moving range of the sliding rack 720, and the rotation inertia generated by the inertia flywheel can be kept until the first pull rope 240 and the second pull rope 250 are completely accommodated in the rope path of the embodiment.

Based on the above structure, the inventor found that after the sliding rack 720 is disengaged from the transmission gear set 730, the rotational inertia of the inertia flywheel 740 needs to drive the three gears of the transmission gear set 730 to operate, so that a great amount of rotational inertia loss is generated, which is not beneficial to the accommodation of the first rope 240 and the second rope 250, and therefore, the present embodiment further improves the structure of the rope pulling and retracting device 700.

Specifically, the mounting bracket 710 of the present embodiment is provided with a second sliding groove 711, a rotating shaft frame 712 is slidably mounted on the second sliding groove 711, and a fourth transmission gear 734 and an inertia flywheel 740 are mounted on the rotating shaft frame 712 through a rotating shaft; a return spring 713 is installed in the second sliding groove 711, one end of the return spring 713 is connected with the second sliding groove 711, and the other end of the return spring 713 is connected with the rotating shaft frame 712; the shaft bracket 712 is provided with a stop part 7121 which extends outwards; when the sliding rack 720 moves from the third position between the first position and the second position of the present embodiment to the first position of the present embodiment, the first pushing portion 721 is abutted against the blocking portion 7121 to drive the rotating shaft frame 712, the fourth transmission gear 734 and the inertia flywheel 740 to slide in the direction away from the third transmission gear 733, when the sliding rack 720 is at the first position, the fourth transmission gear 734 and the third transmission gear 733 are disengaged, so that the inertia flywheel 740 only drives itself and the fourth transmission gear 734 coaxial therewith to rotate under inertia, thereby avoiding unnecessary transmission loss, and the pressing of the blocking portion 7121 by the first pushing portion 721 is released, and the rotating shaft frame 712 of the present embodiment is driven by the return spring 713 to return to the engagement with the third transmission gear 733, so that the fourth transmission gear 734 returns to the engagement with the third transmission gear 733.

In addition, the inertial flywheel 740 drives the first pull rope 240 and the second pull rope 250 to contract at a higher speed, the first metal pendant 260 and the second metal pendant 270 collide at the end of the rope path, and the problem that the pull rope partially extends out again under the collision force is likely to occur, for this, in this embodiment, the mounting bracket 710 is provided with the power supply 750 and the elastic switch button 760 for switching on and off the power supply 750, the rope path has a first end 221 port and a second end 222 port, the first end 221 port is provided with the first electromagnetic ring 770, the second end 222 port is provided with the second electromagnetic ring 780, and the first electromagnetic ring 770 and the second electromagnetic ring 780 are both connected with the power supply 750; the sliding rack 720 is provided with a second pushing portion 722, when the sliding rack 720 moves to the second position, the second pushing portion 722 presses the elastic switch button 760, and the first electromagnetic ring 770 and the second electromagnetic ring 780 generate magnetism to attract the first metal pendant 260 and the second metal pendant 270, so as to prevent the first metal pendant 260 and the second metal pendant 270 from separating from the first port 221 and the second port 222.

In order to realize the position limitation of the sliding member 230, in the embodiment, the first sliding slot 220 is provided with a first elastic limiting member 223 at the first end 221, the first sliding slot 220 is provided with a second elastic limiting member 224 at the second end 222, the sliding member 230 slides to the first end 221 to be in limit fit with the first elastic limiting member 223, and the sliding member 230 slides to the second end 222 to be in limit fit with the second limiting member, so that the sliding member 230 is prevented from resetting after moving to the first end 221, and the accommodating state of the pull rope is ensured.

In addition, because the size of the inertia flywheel 740 is small, if the wound rope is easily unable to be limited and fixed after being wound for a plurality of turns, the rope is easily separated from the rope winding groove, therefore, the first rope 240 is designed to include the first part 241 and the second part 242 which are integrally connected, the cross-sectional size of the first part 241 is smaller than that of the second part 242, that is, the first part 241 is thin, and the first part 241 is located in the rope path and connected with the first rope winding groove 741; similarly, the second pull rope 250 of the present embodiment is designed to include a third portion 251 and a fourth portion 252 integrally connected, the third portion 251 has a smaller cross-sectional dimension than the fourth portion 252, and the third portion 251 is located in the rope path and connected to the second rope winding groove 742.
