Technical Field

The invention relates to an emergency lifesaving appliance, in particular to a belt buckle with a window breaking function.

Background

The window breaking hammer is an emergency tool for dealing with emergencies, is usually arranged in a vehicle and is used for breaking windows of the vehicle in the case of emergencies so as to ensure that passengers can safely escape. The principle of the window breaking hammer is that a point is firstly hit on the window glass by the tip of the window breaking hammer to break the surface of the window glass, after the point is broken, the glass can be diffused and broken, and people in a car can easily break the window to escape from the car.

Nowadays, the number of motor vehicles in China is 3 hundred million, wherein private cars account for the vast majority, and generally, although window breaking hammers are equipped in most private cars, the window breaking hammers are rarely used, and many car owners can randomly place the window breaking hammers at a certain position. The hidden troubles brought by the method are as follows: when the vehicle meets an emergency, the survival time is only ten seconds generally, and at the moment, if the vehicle is still impacted, people in the vehicle can hardly find the window breaking hammer in a messy vehicle under the condition of confusion. This reduces the chances of survival of the person who could otherwise escape.

After searching the existing documents, the information about the lifesaving hammer device is inquired as follows:

1. a vehicle charger with a window breaking function; application No.: cn201720271673. x; the applicant: jun and International Inc.; Abstract: the utility model provides a car fills with broken window function, its includes the shell, and it still includes: the charging assembly is arranged on the shell; the window breaking assembly comprises a window breaking hammer and a buffering insulating part, one end of the buffering insulating part is connected with the shell, and the other end of the buffering insulating part is movably connected with the window breaking hammer, so that acting force generated during movement of the window breaking hammer can be buffered and reduced by the buffering insulating part; the window breaking hammer is electrically connected with the charging assembly. It can solve the problem that the contact between the automobile charger and the cigarette lighter is poor due to the bumping of the automobile.

2. A mobile phone with a spiral window breaking hammer head; application No.: CN 201020695468.4; the applicant: shanghai Huaqin communications technologies, Inc.; and (3) abstract: the utility model provides a cell-phone with spiral broken window tup, includes the cell-phone body, the top of cell-phone body is equipped with a take internal screw thread helical pipeline, be equipped with one in the helical pipeline and break the window tup, the surface of the one end of broken window tup is equipped with the screw thread, with helical pipeline's internal thread matches and screws in and out, and the other end is equipped with the impact head, the utility model discloses a cell-phone with spiral broken window tup is small, is convenient for hand-carry, and can be very convenient break firm materials such as glass when meetting accidents such as traffic accident when the user, in time withdraws the scene of accident.

However, the vehicle or the mobile phone can be thrown away from the original position when the vehicle is impacted or overturned, so that the lifesaving tool cannot be found or the time needs to be found, and the vehicle is not favorable for being unfolded for self rescue immediately.

Disclosure of Invention

The invention aims to provide a belt buckle with a window breaking function, wherein a user can immediately unfasten a belt at the first time of accident injury, unscrew a collision head and knock a vehicle window to achieve the effect of immediate self rescue; the belt with the window breaking function cannot be separated from a human body no matter any emergency occurs on site, and has the characteristics of good self-rescue timeliness and convenience in taking out; in the normal state that the belt buckle can not be used, the impact head can be retracted in the belt buckle, so that the impact head is prevented from touching a human body or other parts to cause human body injury.

The technical scheme of the invention is realized as follows:

a belt fastener with a window breaking function is characterized in that a hole is formed in the middle of the belt fastener, a knob is arranged on the outer side of the hole, and a striking head capable of freely moving up and down is arranged at the position of the through hole in the middle of the knob. In daily life, the impact head is positioned below and hidden in the belt buckle, when an emergency situation comes, the impact head is lifted and exposed outside, and a user unlocks the belt, so that the impact head can knock a vehicle window to break the window; the impact head may be made of steel or other hard materials.

The impact head is divided into an impact tip part from top to bottom, and the impact tip part is used for breaking the window; the surface of the middle part of the impact head is provided with an external thread which is matched with an internal thread arranged at a through hole in the middle of the knob; the function that the knob is rotated, and the internal thread of the knob drives the impact head to ascend and descend can be realized; the base of the impact head is in contact with the inner wall of the hole in the middle of the belt buckle for limiting, so that the self-rotation of the impact head is limited, and a stabilizing effect is achieved, so that the impact head is more stable and more easy to apply force when the vehicle window is knocked;

the protruding part of the knob is matched and combined with a groove arranged on the belt buckle, a bearing is arranged at the groove, and the bearing is in contact with the inner wall of the protruding part of the knob and the groove; the bearing enables the knob to rotate more smoothly and conveniently, and meanwhile, the knob can be connected with the belt buckle more firmly.

The middle hole of the belt fastener is square, the shape of the middle hole of the belt fastener is matched with that of the square base of the impact head, and the square base is in contact with the middle hole of the belt fastener to play a role in limiting and limiting the rotation of the impact head.

The side wall of the base is provided with a groove, a pressure spring is arranged in the groove, a positioning ball is fixed on the outer side of the pressure spring, and the shape of the positioning ball is matched with a spherical groove arranged at a corresponding position on the inner side of a hole in the middle of the belt buckle; the spherical groove is provided with an ascending position and a descending position. When the positioning ball is matched with the descending ball groove, the impact head is positioned at the descending position, and cannot be easily moved without the action of larger external force; when a user forcibly twists the knob, the positioning ball overcomes the shrinkage of the pressure spring, the impact head rises, and when the impact head reaches the topmost position, the positioning ball is embedded into the spherical groove of the rising position and positioned, and the impact head cannot shrink downwards without the action of external force of a large twisting knob.

Compared with the prior art, the invention has the prominent substantive characteristics and remarkable progress that:

1. according to the belt buckle with the window breaking function, when the belt buckle is injured by an accident, a user can immediately unfasten the belt, unscrew the impact head and knock the window of the vehicle, so that the effect of immediate self rescue is achieved; the timeliness is good, the operation is convenient, and the escape probability of the trapped people in the vehicle is greatly improved.

2. According to the belt buckle with the window breaking function, when the belt buckle is not in use, the impact head is hidden inside the belt buckle, the daily function and use of a belt are not affected, and the impact head cannot easily protrude to cause damage to people or objects; when the tool is in use, the striking head can be lifted only by rotating the knob, and the operation is quick and convenient.

3. The invention has the advantages of simple structure, firmness, durability, easy maintenance and low cost, the manufactured cost is not more than 15 yuan through measurement and calculation of the applicant, the price is similar to the price of a newly bought window breaking hammer, and the invention has great popularization potential.
