Description

Technical Field

[0001] This invention relates to the field of security equipment technology, and in particular to a stun gun for security purposes. Background Technology

[0002] Existing stun batons used by security personnel are 50-60 cm long rods that are hung on the waist. Because they are relatively long, they are not very convenient to use. Security personnel also carry walkie-talkies, flashlights, etc. on their waists, which takes up space and is quite cumbersome. There is an urgent need for an integrated stun baton that can extend, retract, and spray water, thereby reducing the burden on security personnel.

[0003] Among existing patents, application number 201810097918.0, entitled "A Retractable Security Stun Gun," discloses that the retractable security stun gun includes a baton body, an electric shock head, and a handle. The baton body and the handle are detachably connected, both of which are hollow structures, and the baton body is a telescopic tube. A sleeve is provided at the end of the baton body away from the handle, and the electric shock head is fixed to the periphery of the sleeve at the end away from the baton body. A high-intensity lighting lamp is fixed inside the sleeve. A loudspeaker is movably connected to the end of the handle away from the baton body. This patent can only extend and retract, and cannot spray liquid, which is inconvenient.

[0004] Another patent application, CN201110066863.5, entitled "Liquid-Spraying Stun Gun," discloses a stun gun with a stick-shaped, long-gun-shaped, or short-gun-shaped body and an electronic booster device. Unlike existing technologies, the stick or gun body is equipped with a device that can spray a conductive liquid. The conductive liquid is a salt water mixture or a liquid with low resistance. This stun gun is not telescopic and is inconvenient to carry. Furthermore, the liquid spraying of this patent requires a pump for pressurization, which is prone to malfunction. Summary of the Invention

[0005] The purpose of this invention is to provide a security stun gun that is retractable, easy to carry, and capable of spraying liquid, thus achieving multiple functions in one baton.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A security stun gun includes a handheld tube, a telescopic tube that is snapped into the handheld tube, a spraying device disposed on the telescopic tube, and a telescopic device and a snapping device disposed between the handheld tube and the telescopic tube.

[0007] Furthermore, the telescopic tube is slidably connected to the handheld tube, and the telescopic device includes springs disposed at one end of the telescopic tube and one end of the handheld tube.

[0008] Furthermore, the locking device includes a slide rail, a locking part, and a handle slidably connected to the slide rail on the handheld tube. The slide rail is arranged along the length direction of the handheld tube, and the locking part is parallel to the slide rail. The slide rail and the locking part are in communication. The handle is fixedly connected to the telescopic tube.

[0009] Furthermore, the spraying device includes a liquid storage tank and a power device for spraying the liquid in the storage tank; the liquid storage tank is fixed inside the telescopic pipe.

[0010] Furthermore, the top of the telescopic tube is provided with a plug, and the inside of the telescopic tube is provided with a convex ring, with the liquid storage tank being snapped between the plug and the convex ring.

[0011] Furthermore, the storage tank is provided with a liquid outlet, which is sealed with a first membrane, and the plug is provided with a spray hole; the liquid outlet corresponds to the spray hole.

[0012] Furthermore, the power unit includes a high-pressure gas tank installed inside the telescopic tube; the high-pressure gas tank is connected to the liquid storage tank via a valve; the bottom of the liquid storage tank is provided with an air inlet, which is sealed with a second diaphragm.

[0013] Furthermore, the air inlet is provided with a pipe connector, which is connected to the valve, and the pipe connector is provided with a needle-punching part for piercing the second membrane.

[0014] Furthermore, the needle-piercing part includes a needle tip slidably connected to the pipe connector, a baffle plate disposed at the end of the pipe connector, and a tension spring disposed between the baffle plate and the needle tip; the needle tip is provided with a vent hole; the baffle plate is provided with an air inlet hole; after the second membrane is pierced by the needle tip, the gas in the air inlet hole enters the liquid outlet tank through the vent hole.

[0015] Furthermore, the outer wall of the handheld tube is provided with an insulating sleeve.

[0016] The positive effects of this invention are: By setting up a liquid storage tank, a high-pressure gas tank, and a valve, opening the valve causes the high-pressure gas in the high-pressure gas tank to spray out the liquid in the liquid storage tank. The telescopic tube is designed to prevent accidental ejection of the snap-fit ​​device. When using the stun gun, you can pull the handle down and then pull the handle into the slide. Under the action of the spring force, it can be quickly extended. Through the needle-piercing section, high-pressure gas pushes the needle tip to puncture the second membrane, rapidly introducing the high-pressure gas into the storage tank. The high-pressure mixture then ruptures the first membrane, ejecting the mixture. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figures 1 to 5 As shown, A security stun gun includes a handheld tube 1, a telescopic tube 2 that is snapped into the handheld tube 1, a liquid spraying device provided on the telescopic tube 2, and a telescopic device and a snapping device provided between the handheld tube 1 and the telescopic tube 2.

[0021] The spray nozzle 23 of the spraying device is located on the telescopic tube 2, and the switch (valve 6) of the spraying device is located on the handheld tube 1.

[0022] The telescopic tube 2 can slide inside the handheld tube 1 via the telescopic device, thereby lengthening the stun gun; the telescopic tube 2 can be locked onto the handheld tube 1 when not in use via the locking device; the telescopic tube 2 can rotate inside the handheld tube 1, facilitating the locking device to engage.

[0023] like Figure 1 As shown, the telescopic tube 2 is slidably connected to the handheld tube 1; The telescopic device includes a spring 5 located at one end of the telescopic tube 2 and one end of the handheld tube 1. When the stun gun is in use, the locking device is released, the spring 5 extends, causing the telescopic tube 2 to extend. When retracted, like Figure 2 As shown, the locking device includes a slide rail 11 on the handheld tube 1, a locking part 12, and a handle 24 slidably connected to the slide rail 11; The slide 11 is arranged along the length of the handheld tube 1, and the locking part 12 is L-shaped; The locking part 12 has one end parallel to the slide rail 11; the locking part 12 is much shorter than the slide rail 11, as long as it is larger than the diameter of the handle 24; the slide rail 11 and the locking part 12 are connected; the handle 24 is fixedly connected to the telescopic tube 2. In detail, the handle 24 is threadedly connected to the telescopic tube 2. The spraying device includes a liquid storage tank 4 and a power device for spraying liquid from the liquid storage tank 4; the liquid storage tank 4 is fixed inside the telescopic pipe 2.

[0024] The detailed structure is as follows: the top of the telescopic tube 2 is provided with a plug 22, the middle of the telescopic tube 2 is provided with a convex ring 21, and the liquid storage tank 4 is snapped between the plug 22 and the convex ring 21; The plug 22 is threaded to the inner wall of the telescopic tube 2. Tightening the plug 22 can press the liquid storage tank 4 onto the convex ring 21 to prevent shaking.

[0025] like Figure 3 As shown, the liquid storage tank 4 is provided with a liquid outlet 32, which is sealed with a first membrane 33, and the plug 22 is provided with a spray hole 23; the liquid outlet 32 ​​corresponds to the spray hole 23.

[0026] The power unit includes a high-pressure gas tank 3 installed inside the telescopic pipe 2; the high-pressure gas tank 3 is connected to the liquid storage tank 4 through a pipeline and a valve 6; the bottom of the liquid storage tank 4 is provided with an air inlet 36, which is sealed with a second membrane 34.

[0027] Both the first film 33 and the second film 34 are made of plastic film.

[0028] The outer wall of the handheld tube 1 is provided with an insulating sleeve 7 to prevent the stun gun from causing injury to the holder.

[0029] The principle of the electric baton in this application is common knowledge and will not be elaborated further.

[0030] The working process of this invention is as follows: When the stun gun needs to be turned on, move the handle 24 downward along the locking part 12, and then move the handle 24 to the right along the slide 11. When the handle 24 enters the slide 11, the telescopic tube 2 extends upward under the action of the spring 5. When the handle 24 reaches the top of the slide 11, the telescopic tube 2 stops moving. When liquid spraying is required, valve 6 is opened by hand, and compressed gas (usually nitrogen) in high-pressure gas tank 3 is sprayed out and flows through the pipeline to the second membrane 34. Under the action of high-pressure gas, the second membrane 34 ruptures, and the high-pressure gas drives the liquid in the storage tank 4 to exert pressure on the first membrane 33. The first membrane 33 ruptures, the outlet 32 ​​opens, and the liquid in the storage tank 3 mixed with gas is sprayed out through the spray hole 23.

[0031] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 6 As shown, The air inlet 36 is provided with a pipe connector 35, which is connected to the valve 6; In order to quickly puncture the second membrane 34 and allow high-pressure gas to smoothly enter the liquid storage tank 4, thereby driving the liquid to be sprayed out, the pipe joint 35 is provided with a needle-piercing part for puncturing the second membrane 34.

[0032] The needle-piercing part includes a needle tip 37 slidably connected to the pipe connector 35, a baffle 41 disposed at the end of the pipe connector 35, and a tension spring 38 disposed between the baffle 41 and the needle tip 37; the needle tip 37 has a vent hole 39; the baffle 41 has an air inlet hole; after the second membrane 34 is pierced by the needle tip 37, the gas in the air inlet hole enters the liquid outlet tank 4 through the vent hole 39. The two ends of the tension spring 38 are fixed to the needle tip 37 and the baffle respectively to prevent the needle tip 37 from piercing the membrane due to vibration.

[0033] When valve 6 is opened, the gas in the high-pressure gas tank 3 enters the pipe joint 35 through the pipeline. The gas pushes the needle tip 37 through the air inlet, and after overcoming the resistance of the tension spring 38, the needle tip 37 pierces the second membrane 34 upward. The high-pressure gas in the high-pressure gas tank 3 enters the air inlet of the pipe joint 35 through valve 6 and then enters the liquid storage tank 4 through the vent 39. The pressure in the liquid storage tank 4 increases, causing the first membrane 33 to rupture. The gas-liquid mixture is then sprayed out through the liquid outlet 32 ​​and the spray nozzle 23.

[0034] Example 3 The difference between this embodiment and Embodiment 2 is that: like Figure 4 As shown, To avoid repeated use of the stun gun after spraying liquid, a liquid adding device is provided. The liquid adding device is a liquid adding valve 31 installed on the liquid storage tank 4. The liquid adding valve 31 is a one-way valve to prevent liquid from flowing out of the liquid storage tank 4 due to improper operation. After the liquid in the storage tank 4 is used up, first seal the air inlet 36 of the storage tank 4 with a plastic film, then add liquid into the storage tank 4 through the liquid adding valve 31. When it is observed that the liquid is full at the liquid outlet 32, stop adding liquid and seal the liquid outlet 32 ​​with a plastic film.

[0035] The gas in the high-pressure gas tank 3 needs to be filled by a professional manufacturer, and it also needs to be removed and refilled by a professional manufacturer after use.

[0036] Example 4 This embodiment has a basically the same structure as Embodiment 1; The difference is that, like Figure 5 As shown, a laser pointer 42 is provided on the top of the wall of the telescopic tube 2 or on the plug 22. When needed, the laser pointer 42 can be turned on for illumination.

[0037] By integrating the laser pointer 42, staff can avoid carrying multiple devices and having to retrieve various equipment separately when performing tasks on the spot, which would affect their reaction time. The above-described embodiments are detailed and specific, illustrating preferred embodiments of the present invention. They are only used to illustrate the technical ideas and features of the present invention, with the aim of enabling those skilled in the art to understand the content of the present invention and implement it accordingly. However, they are not limited to the present invention, and the patent scope of the present invention cannot be limited by this embodiment alone. That is, any equivalent changes or modifications made to the spirit disclosed in the present invention, without departing from the structure of the present invention, such as local improvements within the system and modifications or transformations between subsystems, are still within the patent scope of the present invention.
