Abstract
Description
Technical Field
[0001] This utility model relates to a window breaker. Background Technology
[0002] Currently, window breakers are complex to operate and can significantly impact rescue time during escape, making it easy to miss the optimal escape window. Utility Model Content
[0003] To solve the above problems, this technical solution provides a window breaker.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A window breaker includes a handheld tube with a pusher resiliently fitted inside the handheld tube. The end of the pusher is provided with a penetrating head for breaking tempered glass. A limiting part is resiliently fitted on the outer periphery of the pusher. A limiting protrusion is provided on the inner wall of the handheld tube for pushing the limiting part inward. The breaker also includes a pusher tube movably disposed on one side of the handheld tube and abutting against the limiting part.
[0006] In some embodiments, the handheld tube is provided with a mounting part, the mounting part is provided with a support rod connected to the pushing part, and a first spring is sleeved on the outer periphery of the support rod.
[0007] In some embodiments, the support rod is a screw and is threadedly engaged with the pusher.
[0008] In some embodiments, two limiting portions are symmetrically provided, and a second spring is provided between the two portions.
[0009] In some embodiments, the two sides of the limiting protrusion are designed to be guides.
[0010] In some embodiments, the handheld tube has a first step, and the push tube has a second step opposite to the first step.
[0011] In some embodiments, the height of the limiting protrusion is greater than the thickness of the inner wall of the push cylinder.
[0012] In some embodiments, the window breaker is made of metal.
[0013] The beneficial effects of this application are:
[0014] This application is easy to operate. The user holds the handpiece firmly and then pushes the pusher inward with the other hand. Since the pusher abuts against the limiting part, pushing it causes the pusher to move inward until it passes the limiting protrusion. Only then can the limiting part move inward. At this time, the elastic part of the pusher recovers, which can drive the piercing head to push outward, thereby causing the piercing head to hit the glass. By repeating this process, the tempered glass can be shattered. Attached Figure Description
[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0016] Figure 1 This is a cross-sectional schematic diagram of an embodiment of the present utility model;
[0017] Figure 2 This is an omitted schematic diagram of an embodiment of the present invention. Detailed Implementation
[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] Please refer to Figure 1-2 As shown, a window breaker includes a handheld tube 1, a pushing part 2 elastically fitted inside the handheld tube 1, a penetrating head 3 for breaking tempered glass at the end of the pushing part 2, a limiting part 4 elastically fitted on the outer periphery of the pushing part 2, a limiting protrusion 5 for pushing the limiting part 4 into the inner wall of the handheld tube 1, and a push tube 6 movably disposed on one side of the handheld tube 1 and abutting against the limiting part 4.
[0020] This application is easy to operate. The user holds the handpiece firmly and then pushes the pusher inward with the other hand. Since the pusher abuts against the limiting part, pushing it causes the pusher to move inward until it passes the limiting protrusion. Only then can the limiting part move inward. At this time, the elastic part of the pusher recovers, which can drive the piercing head to push outward, thereby causing the piercing head to hit the glass. By repeating this process, the tempered glass can be shattered.
[0021] In this embodiment, the handheld tube 1 is provided with a mounting part 7, and the mounting part 7 is provided with a support rod 8 connected to the pushing part 2. A first spring 9 is sleeved on the outer periphery of the support rod 8. The support rod plays a limiting role, so that the pushing part can only move back and forth. In addition, the first spring provides a restoring force to apply force to the pushing part to break the tempered glass.
[0022] In this embodiment, the support rod 8 is a screw and is threadedly engaged with the push part 2. It not only serves as a limit, but also allows the penetration stroke to be changed by rotating the push part.
[0023] In this embodiment, two limiting parts 4 are symmetrically provided, and a second spring 10 is provided between the two.
[0024] In this embodiment, the two sides of the limiting protrusion 5 are designed with guides, which can be arc-shaped or inclined, and the guiding force makes it easier for the limiting part to move into the interior.
[0025] In this embodiment, the handheld tube 1 is provided with a first step 11, and the push tube 6 is provided with a second step 12 opposite to the first step 11, which are matched to limit the movement and prevent the two from separating.
[0026] In this embodiment, the height of the limiting protrusion 5 is greater than the thickness of the inner wall of the push cylinder 6, so that when the limiting part enters the interior, the pushing part can extend through the hand-held part. At this time, the second spring is still compressed, and the end of the limiting part contacts the interior of the push cylinder. The user only needs to pull the push cylinder out completely past the limiting part, and the limiting part and the push cylinder will re-abut, allowing the next operation to begin.
[0027] In this embodiment, the current window breaker is made of plastic, which melts due to high temperatures during a fire, affecting rescue efforts. This new window breaker is made of metal, making it more heat-resistant.
[0028] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
