Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-3, an embodiment of the present invention provides a glass breaker 100, which is installed on a car body 200 close to the top corner of the window glass 300, where the top corner of the window glass 300 is the The weakest position of the window glass 300 is easily broken. The glass breaker 100 includes a base 6 fixed on the vehicle body 200, a pivot seat 2 fixed on the base 6, and a breaking hammer 1; The handle 11 pivoting in the plane of the 300 is fixedly connected to the head of the handle 11 and faces the sharp cone 12 of the window glass 300 . Preferably, the pointed cone 12 is made of hard alloy material; the handle rod 11 pivots around the pivot seat 2 to drive the pointed cone 12 into the window glass 300 to break it.

As shown in Figure 3, since the glass breaker 100 is installed on the car body 200 close to the top corner of the window glass 300, and the breaking hammer 1 is pivotally connected to the pivot seat 2 through its handle 11, the handle 11 is equivalent to For a lever, the pivot joint is equivalent to the fulcrum of the lever. When an emergency occurs, the passenger only needs to pull the tail of the handle 11 with his hand, and the head of the handle 11 will pivot around the pivot seat 2 to drive the lever. The sharp cone 12 penetrates and punctures the window pane 300 . Since the window glass 300 is tempered glass, the internal stress balance of the cracked glass is destroyed immediately, so that the entire window glass 300 is broken. The glass breaker 100 of the present invention can break glass without swinging an arm and applying force in a crowded and panic environment, and the operation is simple and flexible. In order to facilitate passengers to quickly find the glass breaker 100 , preferably, the glass breaker 100 is installed on the vehicle body 200 near the four top corners of the window glass 300 .

It is inevitable that the vehicle will vibrate due to bumps during the running process. The breaking hammer 1 of the glass breaker 100 of the present invention will also vibrate with the vehicle body 200. The sharp cone 12 of the breaking hammer 1 may even collide with the window glass 300, thereby generating vibration Noise affects passengers' rest. To this end, as shown in Figures 1-2, in a preferred embodiment of the present invention, a holder 4 for clamping the handle 11 of the breaker 1 is provided on the base 6, which specifically includes a first U Form plate 41, two arc-shaped protrusions 42 that are arranged on the inner side of the two side plates of the first U-shaped plate 41 correspondingly; Towards the tail of the handle 11, the tail of the handle 11 is snapped between the two arc-shaped protrusions 42 and the bottom plate by pivoting around the pivotal seat 2 or the two arc-shaped protrusions 42 are forced away so that the tail of the handle 11 Pass through between the two arc-shaped protrusions 42 and separate from the card holder 4 . Specifically, the distance L1 between the two side plates of the first U-shaped plate 41 needs to be greater than the width of the tail of the handle 11 in the direction of the pivot axis A, and the distance L2 between the two arc-shaped protrusions 42 needs to be smaller than the width of the handle 11. The width of the tail in the direction of the pivot axis. The bottom plate of the first U-shaped plate 41 and the base 6 can be fixed by screw connection or welding. If the base 6 and the first U-shaped plate 41 are all metal materials, it is preferably fixed by welding with firm connection. As shown in Figure 2, when the vehicle does not have an emergency, since the distance between the arc-shaped protrusions 42 is smaller than the width of the tail of the handle 11 in the direction of the pivot axis, the tail of the handle 11 is clamped between the two arc-shaped protrusions. 42 and the space enclosed by the side plates to prevent the handle rod 11 from driving the pointed cone 12 to vibrate; Apply force to the opening direction of the first U-shaped plate 41, and the tail of the handle 11 will stretch the two arc-shaped protrusions 42 of the two side plates outward under the action of force, so as to realize the quick separation of the handle 11 and the holder 4 , and finally the handle rod 11 can drive the pointed cone 12 to pivot freely.

The base 6 of the glass breaker 100 can have a variety of structural forms, and the corresponding structural form needs to be determined according to the way of fixed connection with the vehicle body 200. For example, the base 6 can be a flat plate structure, which is provided with dovetail-shaped bar-shaped protrusions , and the corresponding position on the car body 200 needs to be provided with a bar-shaped dovetail groove that matches the bar-shaped bump, and the base 6 is inserted into the bar-shaped dovetail groove through the bar-shaped bump to realize the snap connection with the car body 200 . As shown in Figures 1-2, in a preferred embodiment of the present invention, the base 6 is also a flat plate structure, which has a first plate surface and a second plate surface opposite, and is provided with a plurality of penetrating first plate surfaces and The through hole 61 of the second plate surface, the first plate surface of the flat plate is attached to the surface of the vehicle body, and is fixed on the vehicle body 200 by the screw 400 passing through the through hole 61, and the pivot seat 2 is fixed on the second plate surface of the flat plate. on board. The glass breaker 100 can be quickly and firmly installed on the vehicle body 200 by using fasteners such as screws 400 to realize the fixed connection.

As shown in Figure 1-2, the pivotal seat 2 of the glass breaker 100 can have various structural forms. 11 can be pivotally connected to the double ear plate through the pin shaft passing through the through hole, but the double ear plate structure is not easy to achieve a fixed connection with the base 6 . As shown in Figure 1-2, in one embodiment of the present invention, the pivotal seat 2 is a second U-shaped plate, and two through holes are coaxially opened on the two side plates, and the handle rod 11 passes through the two through holes. The pivot 3 is pivotally connected to the second U-shaped plate, and is located between the two side plates. The outer surface of the bottom plate of the second U-shaped plate is attached to the second plate surface of the flat plate, and can be fixed by screw connection or welding. If both the flat plate and the second U-shaped plate are made of metal, they are preferably fixed by reliable welding.

There are many ways to fix the pointed cone 12 on the head of the handle 11. If the handle 11 is made of metal material, the pointed cone 12 can be fixed on the head of the handle 11 by welding. As shown in Figures 1-2, in a preferred embodiment of the present invention, the pointed cone 12 is threadedly connected to the head of the shank 11, specifically, the pointed cone 12 includes a coaxial integrally connected tip 122 and a rod part 121, the peripheral surface of the rod part 121 away from the tip part 122 is provided with an external thread, the head of the handle rod 11 is provided with a threaded through hole, and the rod part 121 passes through the handle rod 11 through the screwing of the external thread and the threaded hole. A nut 5 is screwed with the external thread of the rod 121 and pressed against the head of the handle rod 11 to lock the pointed cone 12 . The advantage of this threaded connection and the fixing method utilizing the nut 5 to lock is that the shank 11 can be made of metal or other materials, which expands the selection range of the material of the shank 11; the tip of the pointed cone 12 The distance between the portion 122 and the window glass 300 can be adjusted by rotating the rod portion 121 of the cone 12; the cone 12 is detachably connected to the handle rod 11, so that the cone 12 can be easily replaced.
