Description

Technical Field

[0001] This utility model belongs to the technical field of window breaking devices, and relates to a manual window breaking device mounted on the canister of a police tear gas sprayer. Background Technology

[0002] When traffic police inspect vehicles, they often encounter drivers who refuse to lower their windows as required. Traffic police officers do not carry dedicated window-breaking equipment; the only option is the extendable baton. While powerful, the baton requires considerable space and may injure occupants, making it ineffective. However, a dedicated window-breaking device is also inconvenient to carry and use. The best solution is to add window-breaking functionality to their existing equipment. Research on officers' equipment suggests that adding window-breaking functionality to tear gas spray is relatively simple. However, current industry standards specify dimensional requirements for tear gas spray, preventing the direct addition of a window-breaking mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a manual window-breaking device that can be mounted on the canister of a police tear gas spray, and it can break windows quickly and efficiently.

[0004] The technical solution adopted by this utility model is a manual window-breaking device mounted on the canister of a police tear gas sprayer, including a shell, the upper half of the shell being a sleeve end, the lower half being provided with a power spring, the power spring being connected to an impact head, the impact end of the impact head being fixed with a firing pin, the bottom of the lower half of the shell being provided with a base, the base being connected to the shell through at least one set of elastic mechanisms, and a through hole being opened on the base at a position corresponding to the impact head.

[0005] The features of this utility model also include:

[0006] The outer shell is cylindrical, and a partition is fixed in the middle of the outer shell, which divides the outer shell into upper and lower parts.

[0007] The separator has a mounting hole on one side of the lower half of the housing. The end of the impact head is located in the mounting hole and extends out of the mounting hole. The edge of the impact head end extends outward. A retaining ring is fitted on the outside of the mounting hole. The opening edge of the retaining ring extends inward. The inward extension of the retaining ring prevents the outward extension of the impact head end edge from moving out of the mounting hole. A positioning platform is provided on the outer surface of the impact head. The positioning platform is always located outside the mounting hole. The shape of the opening of the retaining ring matches the positioning platform at the end of the impact head for positioning. One end of the power spring is fixed in the mounting hole, and the other end is fixedly connected to the impact head.

[0008] The elastic mechanism includes a return spring, one end of which is fixedly connected to the separator and the other end of which is fixedly connected to the base. It also includes a fixed shaft with both ends fixedly connected to the base. A support rod and a torsion spring are respectively installed on the fixed shaft. The support rod can rotate around the fixed shaft. The torsion spring is sleeved on the fixed shaft. One end of the torsion spring is fixed to the base and the other end is fixedly connected to the support rod. The top of the support rod is provided with a shoulder that matches the positioning platform of the impact head. The shape of the top of the support rod matches the shape of the end face of the opening of the fixed ring. When the position of the positioning platform of the impact head changes from the shoulder at the top of the support rod to the opening of the fixed ring, the top of the support rod moves along the end face of the opening of the fixed ring, the support rod itself rotates, and the torsion spring is compressed.

[0009] The end face of the opening of the fixed ring is a slope, which is a slope that slopes down from the center axis of the fixed ring in the circumferential direction of the outer side of the fixed ring, and the top of the support rod is an arc surface.

[0010] There are two sets of elastic mechanisms, which are symmetrically arranged on both sides of the impact head, and the impact head is located on the axis of the outer shell.

[0011] The bottom surface of the base is equipped with an anti-slip pad.

[0012] The beneficial effects of this utility model are:

[0013] This utility model features a manual window-breaking device mounted on the canister of a police tear gas sprayer. The window-breaking action is simple, the force is controllable, and it prevents flying shards that could injure occupants during the process. Compared to using a police telescopic baton, the operator's movements are less noticeable, minimizing startle and tension for those inside the vehicle, thus reducing the risk of operational errors. It requires minimal operating space; the operator does not need to be aware of the surrounding area when breaking the window, and can immediately use the tear gas sprayer to control the spray if necessary. To use, simply remove the tear gas sprayer from the carrying equipment and press the base of this utility model against the window until the impact head releases. It is reusable, reducing costs; its simple structure allows for maintenance-free operation during its service life. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] This embodiment provides a manual window-breaking device that is mounted on the canister of a police tear gas sprayer, such as... Figure 1 As shown, it includes a housing 1, which is cylindrical. A partition is fixed in the middle of the housing 1, dividing the housing 1 into upper and lower parts. The upper part of the housing 1 is a sleeve end, and a power spring 10 is provided in the lower part. Figure 2 As shown, the police tear gas sprayer 12 is installed on the upper half of the outer shell 1. The power spring 10 is connected to the impact head 3. The impact end of the impact head 3 is fixed with a firing pin 4. The firing pin 4 is made of high-hardness alloy and has a sharp tip, which is used to break the tempered glass of the car window. The lower half of the outer shell 1 is provided with a base 2. The base 2 is connected to the outer shell 1 through two sets of elastic mechanisms. The two sets of elastic mechanisms are symmetrically arranged on both sides of the impact head 3. The impact head 3 is located on the axis of the outer shell 1. The base 2 has through holes at the corresponding positions of the impact head 3. The bottom surface of the base 2 is provided with an anti-slip pad 11 to stabilize the base 2 and prevent it from sliding when breaking the window, thus ensuring the reliability of breaking the window.

[0025] Example 2

[0026] This embodiment provides a manual window-breaking device mounted on the canister of a police tear gas sprayer. Based on embodiment 1, a partition is provided with a mounting hole on one side of the lower half of the outer shell 1. The partition can be a partition plate. A short cylindrical impact head sliding cylinder is fixed at the center of the bottom surface of the partition plate. This impact head sliding cylinder serves as the mounting hole. The end of the impact head 3 is located in the mounting hole, with the impact end extending out of the mounting hole. The edge of the end of the impact head 3 extends outward. A fixing ring 5 is fitted on the outside of the mounting hole. The opening edge of the fixing ring extends inward. The inward extension of the fixing ring prevents the outward extension of the end edge of the impact head 3 from moving out of the mounting hole. A positioning platform is provided on the outer surface of the impact head. The positioning platform is always located outside the mounting hole. The shape of the opening of the fixing ring 5 matches the positioning platform at the end of the impact head 3 to determine the lower stop point of the impact head 3. One end of the power spring 10 is fixed in the mounting hole, and the other end is fixedly connected to the impact head 3. The power spring 10 provides the window-breaking power for the impact head 3. Under the action of the power spring 10, the impact head 3 can slide in the mounting hole of the outer shell 1.

[0027] Example 3

[0028] This embodiment provides a manual window-breaking device mounted on the canister of a police tear gas sprayer. Based on embodiments 1-2, the elastic mechanism includes a return spring 9, one end of which is fixedly connected to a separator, and the other end is fixedly connected to a base 2. Figure 3 As shown, it also includes a fixed shaft 8 that is fixedly connected to the base 2 at both ends. A support rod 6 and a torsion spring 7 are respectively provided on the fixed shaft 8. The support rod 6 can rotate around the fixed shaft 8. The torsion spring 7 is sleeved on the fixed shaft 8. One end of the torsion spring 7 is fixed to the base 2, and the other end is fixedly connected to the support rod 6. The top of the support rod 6 is provided with a shoulder that matches the positioning platform of the impact head 3. The shape of the top of the support rod 6 matches the shape of the end face of the opening of the fixed ring 5. The end face of the opening of the fixed ring 5 is a slope. This slope is a slope that slopes down from the center axis of the fixed ring 5 in the circumferential direction of the outer side of the fixed ring 5. The top of the support rod 6 is an arc surface. When the position of the positioning platform of the impact head 3 changes from the shoulder at the top of the support rod 6 to the opening of the fixed ring 5, the top of the support rod 6 moves along the end face of the opening of the fixed ring 5, the support rod 6 itself rotates, and the torsion spring 7 is compressed.

[0029] The specific usage process of the manual window-breaking device attached to the canister of a police tear gas sprayer is as follows:

[0030] The police tear gas spray 12 is installed on the window-breaking device of this utility model. When it is necessary to break a window, hold the police tear gas spray 12 with one hand and use the base 2 to hold the vehicle window glass. Figure 4As shown, press the base 2 towards the car window. The support rod 6 on the base 2 presses against the impact head 3, meaning the positioning platform of the impact head 3 is located on the shoulder of the support rod 6 and is pushed upward, compressing the power spring 10. Continue pressing until the positioning platform of the impact head 3 is located at the opening of the fixing ring 5, meaning the arc surface of the support rod 6 contacts the inclined surface of the fixing ring 5, as shown. Figure 5 As shown, the top of the support rod 6 slides along the inclined surface of the fixing ring 5, and the support rod 6 opens outward to release the impact head 3, as... Figure 6 As shown, the impact head 3, pushed by the power spring 10, rushes towards the glass and breaks the window instantly through the front-end striking pin 4.

[0031] After the window is broken, the base 2 returns to its original position downwards under the push of the return spring 9, as follows. Figure 7 As shown, during the downward movement, the support rod 6 is pushed open by the positioning platform of the impact head 3. Continuing downward, after the base 2 resets, the shoulder of the support rod 6 again presses against the lower surface of the positioning platform of the impact head 3, meaning the positioning platform of the impact head 3 is located on the top shoulder of the support rod 6, completing the work cycle. To use it again, simply press the base again to perform the window-breaking operation.

[0032] As can be seen from the above, the manual window-breaking device of this utility model, which is mounted on the canister of a police tear gas sprayer, compresses the power spring 10 inside the impact head 3 by pressing down the base 2 and supporting rod 6. After the power spring 10 accumulates kinetic energy, the supporting rod 6 releases the impact head 3, which is pushed by the elastic potential energy of the power spring 10 and impacts the tempered glass of the car window. The high-hardness impact pin 4 breaks the window. During the window-breaking process, the anti-slip pad 11 is in close contact with the car window glass to prevent the manual window-breaking device from sliding on the glass surface, which would reduce the reliability of the window breaking.
