Description

Technical Field

[0001] The utility model belongs to the technical field of security patrol equipment, and particularly relates to a hand-held device for security patrol. Background Art

[0002] With the development of society, people pay more and more attention to security. Security posts are set up in schools, government agencies, hospitals, companies, etc., and security personnel are fully armed. At present, the security tools equipped for domestic security personnel are mostly truncheons, shields, cut-resistant gloves, etc. Among them, the truncheon is used and carried more frequently during patrol. A truncheon is a police and public security riot control equipment that can be used for both attack and defense. Due to its simple structure, small size, and no need for high technology during use, it has become an important protective tool during security patrol. In case of emergency, such as when personal safety is threatened, the security guard can use the truncheon for self-defense or protection. In order to avoid excessive harm caused by the truncheon, generally, the truncheons equipped for security personnel do not have too many counterattack functions and can only perform basic strikes. Security personnel also need to be equipped with other riot control equipment such as tear gas, high-pressure water guns, pepper sprayers, etc. together to effectively subdue lawbreakers and prevent the situation from expanding. This causes security personnel to need to be equipped with multiple explosion-proof equipment during patrol, which is not convenient to carry, and it is also more cumbersome to use multiple equipment when encountering lawbreakers. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides a hand-held device for security patrol. By combining a truncheon with a mace spray, the mace spray can be ejected from the truncheon, which improves the functionality of the truncheon, reduces the number of items carried by security personnel during patrol, and also improves the convenience during operation.

[0004] The solution adopted by the present utility model to solve its technical problems is as follows: A security patrol handheld device includes a main rod body, an extension rod body, and a pneumatic unit. A sealing ring sleeve is fixed at the bottom of the main rod body. The extension rod body is longitudinally and dynamically sealed and sleeved in the main rod body through the sealing ring sleeve, and the extension rod body and the main rod body are connected by a top spring. A storage cavity with an open lower end is provided in the extension rod body. A piston block is fitted in the storage cavity in a matching manner, and a defensive liquid can be filled in the storage cavity. A cap is installed at the lower end of the extension rod body, and a spray hole is provided at the bottom of the cap. The pneumatic unit includes an airbag and an I-shaped piston. The airbag is circumferentially arranged at the handheld part of the main rod body. The I-shaped piston is fixedly sleeved at the top of the extension rod body. A plurality of air vents communicating with the extension rod body are provided at the middle position on the side of the I-shaped piston. A sealed air cavity is formed between the I-shaped piston and the sealing ring sleeve, and a trachea is installed and connected to the I-shaped piston. The lower end of the trachea is fixed at the bottom end of the main rod body. When the I-shaped piston moves to the lowest end of the main rod body, the outlet of the trachea is exactly corresponding to the height of the air vents. A limiting ring is rotatably sleeved at the bottom end of the main rod body. After the extension rod body is retracted into the main rod body, the cap and the limiting ring can be clamped together to limit the extension rod body.

[0005] Further, the inner diameter of the limiting ring is greater than the outer diameter of the cap. A plurality of limiting protrusions are circumferentially arranged on the outer side of the cap and the inner wall of the limiting ring. A clamping groove is formed between adjacent limiting protrusions, and the size of the clamping groove is greater than the size of the limiting protrusions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the drawings and embodiments.

[0019] Please refer to Figures 1-6 , the present utility model provides a technical solution for a security patrol hand-held device: Embodiment

[0020] According to Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a main rod body 1, an extension rod body 2, and a pneumatic unit 6. The extension rod body 2 is longitudinally arranged inside the main rod body 1 and can extend out from the bottom of the main rod body 1. A sealing ring sleeve 11 is fixed at the bottom of the main rod body 1. The extension rod body 2 is movably and sealingly sleeved inside the main rod body 1 through the sealing ring sleeve 11. And the extension rod body 2 and the main rod body 1 are connected by a top spring 5. The upper and lower ends of the top spring 5 are respectively connected to the inner top of the main rod body 1 and the top of the extension rod body 2. Through the cooperation of the top spring 5, the extension rod body 2 can be retracted into the main rod body 1 or ejected from the main rod body 1. A limiting ring 4 is arranged at the bottom end of the main rod body 1. When the extension rod body 2 is retracted into the main rod body 1, the extension rod body 2 can be limited by the limiting ring 4, so that the baton is set as a telescopic structure. When there are no lawbreakers, the security personnel can retract the extension rod body 2 into the main rod body 1 for easy carrying. When encountering lawbreakers, the extension rod body 2 can be instantly ejected from the main rod body 1 to make the baton extend, so as to deter lawbreakers through the baton.

[0021] As Figure 4 shown, a storage cavity 21 with an open bottom is opened inside the extension rod body 2. A piston block 23 is fitted and installed in the storage cavity 21. The part of the storage cavity 21 below the piston block 23 can be filled with defensive liquids, such as pepper spray, tear gas, etc. A cap 3 is installed at the lower end of the extension rod body 2. A spray hole 31 is arranged at the bottom of the cap 3. When the storage cavity 21 is in a negative pressure state, the internal anti-explosion liquid can be sprayed out through the spray hole 31, playing a role of spraying the anti-explosion spray for riot control.

[0022] The pneumatic unit 6 includes an airbag 61 and an I-shaped piston 62. The airbag 61 is circumferentially arranged on the handheld part of the main rod body 1, acting as a protective pad. The I-shaped piston 62 is fixedly sleeved on the top of the extension rod body 2. A plurality of ventilation ports 63 penetrating through the extension rod body 2 are arranged at the middle position on the side of the I-shaped piston 62. And a sealed air cavity is formed inside the main rod body 1 between the I-shaped piston 62 and the sealing ring sleeve 11. A pressure stabilizing breathing hole 12 is opened at the top of the main rod body 1. An air pipe 64 is installed and connected on the I-shaped piston 62. The air pipe 64 is arranged close to the outer surface of the main rod body 1. The lower end of the air pipe 64 is fixed at the bottom end of the main rod body 1. When the I-shaped piston 62 moves to the bottom end of the main rod body 1, that is, when the volume of the sealed air cavity is the smallest, the outlet of the air pipe 64 just corresponds to the height of the ventilation port 63. When the extension rod body 2 extends out from the main rod body 1 under the thrust of the top spring 5, the I-shaped piston 62 moves downward inside the main rod body 1, the volume of the sealed air cavity becomes smaller, and the internal gas is pressed into the airbag 61, making the airbag 61 bulge. And the elastic force of the top spring 5 is greater than the gas pressure when the airbag 61 is fully bulged. After the extension rod body 2 fully extends out, the outlet of the air pipe 64 corresponds to the ventilation port 63. Then the security personnel tightly hold and squeeze the bulged airbag 61 with force, and the gas in the airbag 61 will enter the extension rod body 2 along the ventilation port 63 and push the piston block 23 downward, pressing out the anti-explosion spray inside the extension rod body 2 to deal with lawbreakers.

[0023] A stopper 22 is fixed above the storage chamber 21 and is located below the vent 63 to limit the movement of the piston block 23 and prevent the piston block 23 from crossing over or blocking the vent 63, thereby preventing the pneumatic unit 6 from being started.

[0024] like Figure 5 and Figure 6 As shown, the outer side of the bottom of the extension stick body 2 and the inner wall of the cap 3 are provided with matching threads, the cap 3 is installed on the bottom of the extension stick body 2 in a threaded connection manner, and a sealing gasket 33 is provided on the inner bottom of the cap 3 to seal the bottom end of the extension stick body 2. When the spray in the storage chamber 21 is used up, the cap 3 can be removed and the spray can be replenished in the storage chamber 21 so that it can be reused many times.

[0025] By combining a baton and anti-wolf spray so that the anti-wolf spray can be sprayed from the baton, security personnel no longer need to carry a spray bottle when patrolling. In addition, a lighting lamp can be added to the baton to provide lighting effects, thereby reducing the number of items that security personnel carry when patrolling and improving convenience.

[0026] When in use, the utility model is a handheld device for security patrol. When patrolling, the baton is in a retracted state. When encountering lawbreakers, the security personnel first rotate the limiting ring 4 to completely dislocate the limiting convex strips 32 on the limiting ring 4 and the cap 3, release the limiting state of the cap 3 and the extension stick body 2, and push the extension stick body 2 out of the main stick body 1 through the thrust of the top spring 5 to extend the baton. When the extension stick body 2 is extended outward, the I-shaped piston 62 moves downward in the main stick body 1, the volume of the sealed air cavity becomes smaller, and the air inside the sealed air cavity is released. The body is pressed into the airbag 61 through the air tube 64 to make the airbag 61 swell. When the extension stick body 2 is fully extended, the outlet of the air tube 64 just corresponds to the vent 63. Then, when using the baton to suppress violence, the swollen airbag 61 can be tightly grasped and squeezed to press the gas in the airbag 61 into the extension stick body 2 through the air tube 64 and the vent 63. The piston block 23 is pushed downward by the air pressure to spray the explosion-proof spray in the extension stick body 2. By combining the baton and the explosion-proof spray to fight against lawbreakers, the ability to deal with lawbreakers is improved. Example

[0027] On the basis of the first embodiment, Figure 3 and Figure 6As shown in the figure, the limiting ring 4 is rotationally sleeved on the outer side of the bottom of the main rod body 1, and the inner diameter of the limiting ring 4 is greater than the outer diameter of the cap 3. A plurality of limiting ridges 32 are circumferentially arranged on the outer side of the cap 3 and the inner wall of the limiting ring 4. A card slot is formed between adjacent limiting ridges 32, and the size of the card slot is greater than the size of the limiting ridge 32. When retracting the extension rod body 2, first rotate the limiting ring 4 so that the card slot on the limiting ring 4 is aligned with the limiting ridge 32 on the cap 3, and then retract the extension rod body 2 into the main rod body 1. When the extension rod body 2 is retracted into the main rod body 1, the limiting ridge 32 on the cap 3 just passes through the card slot of the limiting ring 4 and is located obliquely above the limiting ridge 32 on the limiting ring 4. Then slightly rotate the limiting ring 4 so that the limiting ridges 32 on the cap 3 and the limiting ring 4 are in clamping contact. Through the mutual clamping of the limiting ridges 32 on the cap 3 and the limiting ring 4, the extension rod body 2 can be stably fixed in the main rod body 1 and retracted.

[0028] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
