Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8 The present invention provides a technical solution: a baton cover with an anti-robbery auxiliary fixing structure, including a base 1, a fixing mechanism 2 movably disposed in the inner wall of the base 1, an installation sleeve 3 rotatably connected to the front end of the base 1, a baton cover body 4 fixedly connected in the inner wall of the installation sleeve 3, an anti-robbery mechanism 5 installed in the inner wall of the baton cover body 4, and a buffer mechanism 6 fixedly disposed in the outer wall of one side of the base 1.

[0028] The fixing mechanism 2 includes a fixing plate 21 and a limiting groove 24. One end of the fixing plate 21 is hinged to the outer wall of the base 1, and a torsion spring is sleeved on the shaft end of the fixing plate 21. A through hole is opened on the outer wall of the fixing plate 21, and a locking plate 22 is slidably arranged on the inner wall of the through hole. A limiting rod 23 is fixedly connected to both sides of the front axis of the locking plate 22. The limiting groove 24 is opened at the bottom of the base 1, and two sets of limiting grooves 24 are symmetrically opened about the axis of the base 1. A limiting member 25 is fixedly arranged in the inner wall of both sets of limiting grooves 24.

[0029] The limiting rod 23 includes a limiting block 231 and a slot 232. The rear end of the limiting block 231 is fixedly connected to the end of the limiting rod 23. The top side of the limiting block 231 has a machined inclined surface, and the front end of the limiting block 231 has a machined conical surface. The slot 232 is opened on the side wall of the limiting rod 23. By inserting the locking plate 22, the limiting rod 23 on the locking plate 22 passes through the waist belt and is inserted into the base plate 62. It is limited by the movable rod 252, so that when it is pulled, the connection structure between the base 1 and the waist belt is increased by the two sets of limiting rods 23, making it less likely to be pulled off. Moreover, the buffer mechanism 6 can buffer the force during repeated pulling and provide protection.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 7 As shown, the limiting component 25 includes a movable compartment 251, which is formed on the side wall of the limiting groove 24 and is connected to the limiting groove 24. A movable rod 252 is slidably disposed in the inner wall of the movable compartment 251, and a telescopic spring is sleeved on the outer wall of the movable rod 252. A connecting rod 253 is fixedly connected to the end of the movable rod 252, and the cross-section of the connecting rod 253 is L-shaped. A push rod 254 is fixedly connected to the top of the connecting rod 253, and the push rod 254 is horizontally positioned with respect to the outer wall of the base 1. The two sets of limiting rods 23 at the bottom of the locking plate 22 pass through the waistband until they are inserted into the limiting groove 24. At this time, the movable rod 252 in the limiting groove 24 and the bottom of the limiting rod 23 press against each other. However, since the bottom of the limiting rod 23 is tapered, the movable rod 252 first contracts and squeezes the telescopic spring, and at the same time drives the push rod 254 to move, so that the limiting rod 23 is inserted into the limiting groove 24. At the same time, the movable rod 252 moves forward again through the action of the telescopic spring and is inserted into the slot 232 on the limiting rod 23, thus completing the locking.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 7 As shown, the movable rod 252 and the limiting groove 24 are horizontally arranged. The outer diameter of the movable rod 252 matches the inner diameter of the limiting groove 24. The movable rod 252, the connecting rod 253 and the movable chamber 251 are symmetrically arranged in two sets about the axis of the base 1. The two sets of limiting parts 25 and limiting rods 23 are arranged in cooperation to increase the fixing structure between the base 1 and the belt, which facilitates the protection of the equipment.

[0032] In this embodiment, as Figure 1 , Figure 3 and Figure 5As shown, the anti-robbery mechanism 5 includes a rotating sleeve 51. The outer wall of the rotating sleeve 51 is rotatably connected to the inner wall of the baton sleeve body 4 via a bushing. A torsion spring is fitted on the shaft end of the rotating sleeve 51. A V-shaped groove 52 is formed in the inner wall of the rotating sleeve 51. A locking element 53 is connected to one end of the groove 52, and the other end of the groove 52 extends into the inner wall of the baton sleeve body 4. A slider 54 is slidably arranged in the inner wall of the groove 52, and a baton body 55 is fixedly connected to the rear end of the slider 54. The baton body 55 is inserted into the rotating sleeve 51. The officer first presses down on the baton 55. The baton 55 slides through the groove 52 on the rotating sleeve 51 via the slider 54. Since the baton 55 only moves up and down, it presses against the side wall of the groove 52 via the slider 54, causing the rotating sleeve 51 to rotate. The baton 55 then moves to the lowest end of the V-shaped groove 52, pulling it up again. At the same time, the baton 55 presses against the groove 52 via the slider 54, causing the rotating sleeve 51 to rotate again, thus sliding out through the other end of the V-shaped groove 52 for easy removal.

[0033] In this embodiment, as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the locking component 53 includes a movable groove 531, which is formed in the inner wall of the rotating sleeve 51. The movable groove 531 is connected to the sliding groove 52. A blocking rod 532 is horizontally slidably arranged in the inner wall of the movable groove 531. A strong spring is sleeved on the outer wall of the blocking rod 532. The end of the blocking rod 532 extends into the inner wall of the rotating sleeve 51 and is fixedly connected to a push rod 533. The front end of the push rod 533 extends into the outer wall of the sleeve body 4. The push rod 533 and the blocking rod 532 are horizontally arranged. When the sleeve 55 is not removed, if an outsider tries to snatch the sleeve 55 and pulls it forcefully, the slider 54 on the sleeve 55 will... Located at the front end of the slide groove 52, when pulled upwards, the baton 55 cannot be pulled out. At the same time, the slider 54 on the baton 55 will be moved into the movable compartment 251, squeezing the blocking rod 532 to move. This causes the slider 54 to be blocked and locked by the blocking rod 532, making it impossible for outsiders to move the baton 55. Only when the police officer manually presses the top rod 533 located at the side end of the baton sleeve body 4, the blocking rod moves forward, causing the sliding groove at the rear end of the blocking rod 532 to move below the slider 54. At this time, the slider can move downwards, and the above-mentioned pressing operation can be completed, and the baton 55 can be taken out, which is convenient for protecting the baton 55 and preventing theft.

[0034] In this embodiment, as Figure 6As shown, a sliding groove is provided at the axis of the blocking rod 532, and the cross-sectional diameter of the sliding groove matches the diameter of the slider 54. The sliding groove and the slider 54 are set horizontally. With the setting of the sliding groove on the blocking rod 532, when the police officer manually presses the top rod 533 located at the side end of the baton sleeve body 4, the blocking rod moves forward, causing the sliding groove at the rear end of the blocking rod 532 to move to the bottom of the slider 54. At this time, the slider can move downward, releasing the lock of the baton body 55, and can be taken out.

[0035] In this embodiment, as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, a through groove with an arc-shaped cross-section at one end is opened in the inner wall of the sleeve body 4, and the outer diameter of the through groove matches the outer diameter of the push rod 533. The push rod 533 and the blocking rod 532 are both inserted into the inner wall of the rotating sleeve 51, so that the rotation of the rotating sleeve 51 is not affected by the push rod 533 when the through groove is set, which facilitates the normal use of the equipment and ensures the smooth use of the equipment.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the buffer mechanism 6 includes a buffer chamber 61, which is located inside the front outer wall of the base 1. A base plate 62 is slidably disposed in the inner wall of the buffer chamber 61. An installation sleeve 3 is rotatably connected to the front end of the base plate 62. Spring telescopic rods 63 are fixedly connected to the upper and lower ends of the base plate 62, and the fixed ends of the two sets of spring telescopic rods 63 are fixedly connected to the top and bottom walls of the buffer chamber 61, respectively. When pulled by external personnel, the sleeve body 4 will synchronously drive the base plate 62 to move up and down in the buffer chamber 61. The two sets of spring telescopic rods 63 on the upper and lower parts of the base plate 62 will buffer the impact, reduce the pulling force of the sleeve body 4, and prevent damage to the sleeve body 4.

[0037] The method of use and advantages of this invention: The baton sleeve of this anti-robbery auxiliary fixing structure works as follows:

[0038] like Figure 1 and 8As shown in the figure, during equipment installation, the fixing plate 21 is manually pulled, compressing the torsion spring so that the base 1 can be placed on the waist belt. At this time, the fixing plate 21 is released and initially fixed by the torsion spring. Then, the locking plate 22 is manually inserted into the interior of the fixing plate 21. The two sets of limiting rods 23 located at the bottom of the locking plate 22 pass through the waist belt until they are inserted into the limiting groove 24. At this time, the movable rod 252 in the limiting groove 24 and the bottom end of the limiting rod 23 press against each other. However, since the bottom end of the limiting rod 23 is tapered, the movable rod 252 first contracts and compresses the telescopic spring, while driving the push rod 254 to move, so that the limiting rod 23 is inserted into the limiting groove 24. At the same time, the movable rod 252 moves forward again through the action of the telescopic spring and inserts into the slot 232 on the limiting rod 23, thus completing the locking. This increases the fixing structure between the entire base 1 and the waist belt, making the device more resistant to pulling.

[0039] Furthermore, when pulled by external personnel, the baton sleeve body 4 will simultaneously drive the base plate 62 to move up and down in the buffer chamber 61. The two sets of spring telescopic rods 63 on the upper and lower parts of the base plate 62 will buffer the impact, reduce the pulling force of the baton sleeve body 4, and prevent damage to the baton sleeve body 4.

[0040] Finally, when the device is in normal use, the officer must first press down on the baton 55. The baton 55 will slide through the groove 52 on the rotating sleeve 51 via the slider 54. Since the baton 55 only moves up and down, it will press against the side wall of the groove 52 via the slider 54, causing the rotating sleeve 51 to rotate. This causes the baton to first move to the lowest end of the V-shaped groove 52, pulling the baton 55 again and causing it to move upward. At the same time, the baton 55 presses against the groove 52 via the slider 54, causing the rotating sleeve 51 to rotate again, thus sliding out through the other end of the V-shaped groove 52. If outsiders try to grab the baton 55 and pull it forcefully while it is still in use, at this time... The slider 54 on the baton body 55 is located at the front end of the groove 52. When pulled upwards, it cannot pull out the baton body 55. At the same time, it will move the slider 54 on the baton body 55 into the movable compartment 251, squeezing the blocking rod 532 to move. This causes the slider 54 to be blocked and locked by the blocking rod 532, making it impossible for outsiders to move the baton body 55. Only when the police officer manually presses the top rod 533 located on the side end of the baton sleeve body 4, the blocking rod 532 moves forward, causing the sliding groove at the rear end of the blocking rod 532 to move below the slider 54. At this time, the slider can move downwards, and the above-mentioned pressing operation can be completed. The baton body 55 can be removed, which is convenient for protecting the baton body 55 and preventing theft.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
