Description

Technical Field

[0001] This utility model relates to the field of window breaker technology, and in particular to a portable window breaker for fire fighting. Background Technology

[0002] Window breaker typically consists of a sharp striker and a triggering device. The striker increases the pressure on the glass by reducing the contact area. Its kinetic energy comes from a high-strength spring installed inside. When not triggered, the high-strength spring is in a compressed state, storing a large amount of elastic potential energy. When triggered, the spring restriction is released, and the elastic potential energy is instantly transferred to the striker, shattering the glass.

[0003] In practice, existing technologies often break glass by impacting it with the same speed and force, making it impossible to use glass of different strengths. When breaking high-strength or thicker glass, it is necessary to replace it with a higher-specification window breaker, which is very inconvenient. Utility Model Content

[0004] In view of the problem that the above-mentioned or existing technologies cannot be applied to glass of different strengths, this utility model is proposed.

[0057] The ends of the switching block 314 and the release block 225 that are close to each other are both inclined surfaces and are slidably connected to each other.

[0058] Specifically, the energy storage and release component 32 includes an energy storage slide 321. The end of the outer shell 1 is provided with an energy storage slide 321. The end of the energy storage slide 321 is provided with a blocking groove 322. The end of the switching block 314 is provided on the inner wall of the blocking groove 322. The end of the energy storage slide 321 is provided with an impact hole 323.

[0059] Furthermore, the energy storage and release component 32 includes an energy storage slide 321.

The outer wall of the switching block 314 is slidably connected to the inner wall of the energy storage slide 321. The inner wall of the blocking groove 322 is in contact with the end of the switching block 314.

[0060] When the switching block 314 enters the interior of the energy storage slide 321 and slides into the interior of the energy storage slide 321, the conical head at the end of the impact rod 313 is on the same straight line as the impact hole 323 and this straight line is parallel to the axis of the outer shell 1.

[0061] Specifically, the restoration component 33 includes a mounting plate 331, the end of the energy storage slide 321 is provided with a mounting plate 331, the end of the mounting plate 331 is provided with a third spring 333, the end of the third spring 333 is provided with a mounting ring 332, and the mounting ring 332 is provided on the inner wall of the outer casing 1.

[0062] Furthermore, the restoration component 33 includes a mounting plate 331, the end of the energy storage slide 321 away from the impact hole 323 is fixedly connected to the mounting plate 331, the side wall of the mounting plate 331 away from the energy storage slide 321 is fixedly connected to a third spring 333, the end of the third spring 333 away from the mounting plate 331 is fixedly connected to a mounting ring 332, and the outer end of the mounting ring 332 is fixedly connected to the inner wall of the outer casing 1;

[0063] A safety helmet is connected to the outside of the energy storage cylinder 321, and the end of the safety helmet near the outer shell 1 is snapped onto the outer wall of the outer shell 1;

[0064] When using the device, to break the glass, remove the safety helmet and hold the outer shell 1. Press the side of the energy storage cylinder 321 away from the outer shell 1 onto the glass. Squeeze the outer shell 1 towards the glass, causing the energy storage cylinder 321 to move inwards. The energy storage cylinder 321 compresses the third spring 333 via the mounting plate 331, causing the third spring 333 to deform. The energy storage cylinder 321 then presses the switching block 314 against the inner wall of the blocking groove 322, moving the switching block 314 towards the mounting inclined plate 311. The switching block 314 compresses the second spring 315, causing the second spring 315 to deform, thus completing energy storage. When the switching block 314 reaches the contact release block 225, the release block 225 presses the switching block 314, causing the switching block 314 to move the impact rod 313 away from the second spring 315. When the 14th movement reaches the inner wall of the blocking groove 322, the switching block 314 is unlocked. At this time, under the action of the restoring force of the second spring 315, the switching block 314 drives the impact rod 313 to move rapidly towards the impact hole 323 and pass through the impact hole 323, so that the conical head of the impact rod 313 suddenly hits the glass, thereby breaking the glass. This achieves simple glass breaking. Since the device is relatively small and cylindrical, it is very convenient to carry. When the device is finished, the outer shell 1 is retracted. At this time, under the action of the restoring force of the third spring 333, the third spring 333 drives the energy storage cylinder 321 to move away from the outer shell 1 through the mounting plate 331 and return to its original position. At this time, under the action of the restoring force of the second spring 315, the switching block 314 drives the impact rod 313 to return to its original position, thereby achieving automatic restoration of the device for convenient use next time.

[0065] When thicker, harder glass needs to be broken, the drive ring 223 is rotated. The drive ring 223 drives the switching rod 222 and the connecting ring 221 to rotate along the direction of the stop groove 212. When the switching rod 222 rotates into the inside of the switching groove 211, it pulls the drive ring 223 away from the energy storage cylinder 321. The drive ring 223 drives the connecting ring 221 to move along the trajectory of the switching groove 211 through the switching rod 222. The switching rod 222 drives the release block 225 to move along the trajectory of the switching groove 211. At this time, the connecting ring 221 compresses the first spring 214 through the annular rotating plate 224, causing the first spring 214 to undergo compression deformation. When the switching rod 222 moves to the stop groove 212 of the required stop and the cutting... When the drive ring 223 is rotated at the junction of the slot 211, the drive ring 223 drives the switching rod 222 to rotate along the direction of the slot 212. At this time, the switching rod 222 drives the release block 225 to move to the required position, thereby changing the distance between the release block 225 and the switching block 314. When the switching block 314 is unlocked, the deformation degree of the second spring 315 changes, thereby changing the energy stored in the second spring 315. This changes the speed and force of the impact rod 313 hitting the glass after unlocking, thus realizing the change of the device's position. This allows for easy switching of positions to break glass of different thicknesses and hardness, making the device more applicable.

[0066] When the device is not in use, rotating the drive ring 223 causes the switching rod 222 to move into the switching groove 211. At this time, the drive ring 223 is released, and under the action of the restoring force of the first spring 214, the first spring 214 drives the switching rod 222 to move along the direction of the switching groove 211 and enter the interior of the safety locking groove 215 through the connecting ring 221. At this time, since the switching rod 222 cannot rotate in the safety locking groove 215, and the release block 225 is not on the movement trajectory of the switching block 314 when the switching rod 222 is in the safety locking groove 215, the situation of the impact rod 313 popping out and injuring the human body due to accidental contact is avoided, and the device is safely locked.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
