Description

Technical Field

[0001] The invention relates to an auxiliary escape tool, in particular to a window breaker. Background Art

[0002] A window breaker is a tool installed in a closed cabin to assist in escape. It is usually installed in a place that is easily accessible in a closed cabin such as a car. When a closed cabin such as a car catches fire or falls into water, it can be easily taken out and the glass windows and doors can be smashed, thereby helping people escape smoothly.

[0003] At present, the most common window breakers are window hammers that rely on manpower to break windows. The window breaking effect of this window hammer is closely related to the strength of the user. If the explosive force is not enough, it is difficult to break the window. Therefore, electronic window breakers with a certain boost force to improve the window breaking effect have appeared in practical use. However, electronic window breakers have great limitations in use because they need to be charged, and there is a risk of short circuit when used underwater. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a window breaker that is safe and stable to use and can provide sufficient explosive force.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

The above release mechanism has a simple structure and is easy to operate.

[0053] In this specific embodiment, the bottom of the striker 2 is a sharp strike portion 28 with a sharp corner, so that the impact force is uniformly concentrated at the end of the sharp corner, thereby improving the efficiency and effect of breaking the window.

[0054] In this specific embodiment, the first end of the housing 1 is provided with a downwardly protruding abutting boss 16. The abutting boss 16 is used to abut against the window when the window is broken to play a supporting role.

[0055] The specific working principle is as follows: in the unactivated state, the striker 2 is completely received in the housing 1, and the force storage spring 5 is in a compressed force storage state under the locking action of the locking mechanism, and the return spring 7 and the support spring 802 are both in a naturally extended state, so that the striker 2 is received and arranged in the housing 1, so that the corresponding guide inclined surface 431 fits against the inclined groove surface 2111 in the corresponding V-shaped tooth groove 211 and matches the inclination of the guide inclined surface 431, and a locking groove 10 matching the locking angle 432 is formed between the adjacent first guide inclined end surface 3131 and the second guide inclined end surface 82, and the locking angle 432 is arranged in the locking groove 10 at the corresponding position; when it is necessary to break the window, first, the abutting boss 16 is abutted against the window to be broken, and then a downward pressing force is applied to the release button 9, and the release button 9 drives the top plate 801 to move downward, and drives the locking insert 8 to move downward along the guide slot 311, so that the adjacent first guide inclined end surface 313 1 forms a connecting oblique flat end face with the second guide oblique end face 82, releasing the locking effect on the locking angle 432. At this time, the force storage spring 5 is released, providing an explosive force to make the push rod 4 rotate and move downward along the adjacent first guide oblique end face 3131 and the second guide oblique end face 82 to form a connecting oblique flat end face, providing a downward ejection force for the striker 2 to achieve the window breaking operation; when the window breaking operation is completed, the downward pressure applied to the release button 9 is removed, and under the action of the support spring 802, the locking insert 8 moves upward and resets along the guide slot 311, and the push rod 4 moves upward accordingly, so that the force storage spring 5 is compressed and stored again, and a locking groove 10 matching the locking angle 432 is formed again between the adjacent first guide oblique end face 3131 and the second guide oblique end face 82, so as to achieve the locking of the locking angle 432 at the corresponding position, and the striker 2 is also reset under the drive of the reset spring 7 and retracted into the shell 1.

[0056] During the entire working process, the guiding inclined surface 431 of the guiding rib 43 always abuts against the matching inclined groove surface 2111 in the V-shaped tooth groove 211 at the corresponding position. When the guide rib 43 is pressed and the adjacent first guide inclined end face 3131 forms a connected inclined flat end face with the second guide inclined end face 82, the guide rib 43 first moves downward while rotating to the second guide inclined end face 82 corresponding to the positioning protrusion 83. When the guide rib 43 leaves the second guide inclined end face 82 corresponding to the positioning protrusion 83, it directly falls into the corresponding excitation groove 20 and moves downward without rotating, providing an excitation force to the impact rod 2 to achieve instantaneous explosive force window breaking. When the window breaking is completed, the pressing force applied to the release button 9 is removed. At this time, the impact rod 2 is first moved upward by the reset spring 7, pushing the guide rib 43 to move upward along the excitation groove 20, and then connected to the adjacent first guide inclined end face 2111, and with the assistance of the V-shaped tooth groove 211, it moves downward while rotating into the locking groove 10 to achieve force storage and locking.
