Description

Technical Field

[0001] This utility model relates to the field of security equipment technology, specifically to a riot control steel fork with locking function. Background Technology

[0002] Riot control steel forks, also known as police steel forks, are made of high-strength, high-quality steel. They are characterized by high material strength, strong impact resistance, strong bending resistance, and durability. They can withstand the pushing force of up to five people without bending or deforming, providing strong protection. In addition to police use, this product is also suitable for security personnel in schools and kindergartens to improve the school's ability to resist external illegal attacks.

[0003] In the existing technology, the structure of the explosion-proof steel fork is relatively simple and cannot lock the neck of criminals. Because criminals are agile, they often resist when subdued by the explosion-proof steel fork, which makes it easy for them to escape, thus reducing the effectiveness of the explosion-proof steel fork.

[0004] This invention proposes a riot control fork with a locking function to solve the problem that existing riot control forks cannot lock the neck of criminals, thus making it easy for criminals to escape. Utility Model Content

[0005] In order to overcome the problem in the above-mentioned background technology that the explosion-proof steel fork cannot lock the neck of criminals, thus making it easy for criminals to escape.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0007] An anti-riot steel fork with locking function includes a mounting base, with arc-shaped forks rotatably connected to both ends of the mounting base, a lifting structure at the bottom of the mounting base, and a locking structure inside the mounting base.

[0008] The lifting structure is used to drive the mounting base to rise and fall, and the locking structure is used to control the locking or unlocking of the arc-shaped fork.

[0009] Further defining the above technical solution, both sets of arc-shaped forks are connected to rubber pads on their inner sides, which can effectively protect the prisoner's neck and prevent accidents.

[0010] Further defining the above technical solution, the lifting structure includes a housing, a horizontal plate installed at the lower end inside the housing, a threaded column rotatably connected to the top of the horizontal plate, a first motor installed at the bottom of the horizontal plate for driving the threaded column to rotate, a movable sleeve screwed to the outside of the threaded column, and the top of the movable sleeve being fixedly connected to the bottom of the mounting base.

[0011] Further defining the above technical solution, the movable sleeve has sliding rods connected to the bottom of both sides, and the outer shell has sliding grooves on both sides for sliding engagement with the sliding rods.

[0012] Further defining the above technical solution, a handle is fixed to the bottom of the outer shell, and several rubber protrusions are connected to the inner bottom wall of the handle.

[0013] Further defining the above technical solution, the locking structure includes a second motor installed on the inner bottom wall of the mounting base. A rotating shaft is installed at the power output end of the second motor, and a large gear is installed at the end of the rotating shaft opposite to the second motor. Vertical plates are installed at both ends of the inner top wall of the mounting base, and rotating columns are rotatably connected inside the two sets of vertical plates. A small gear is sleeved on the outside of the rotating column for meshing with the large gear.

[0014] Further defining the above technical solution, the locking structure also includes two sets of bevel gears, which are respectively installed at both ends of the rotating column. Both ends of the mounting base are rotatably connected to a connecting shaft. Bevel gears are sleeved on the outer sides of both sets of connecting shafts for meshing with bevel gears. Both sets of connecting shafts extend to the outside of the mounting base and are fixedly sleeved with two sets of arc-shaped forks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) High reliability: When the second motor is working, it drives the large gear to rotate through the shaft, the large gear to rotate, the small gear to rotate, the small gear to rotate, the column to rotate, and then the first bevel gear to rotate. The first bevel gear to rotate drives the second bevel gear and the connecting shaft to rotate, which in turn causes the two arc-shaped forks to rotate and lock the neck of the criminals, thus preventing the criminals from escaping. It has high reliability.

[0017] (2) High flexibility: When the first motor is working, it drives the threaded column to rotate. The rotation of the threaded column drives the movable sleeve to move. When the movable sleeve moves, it drives the arc-shaped fork to move through the mounting seat. Thus, in case of emergency, the overall length of the explosion-proof steel fork can be quickly adjusted to meet the usage requirements of different occasions. Attached Figure Description

[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0024] Example 1: This example provides a riot control fork with a locking function, such as... Figure 1 and Figure 2 As shown, this invention solves the problem that existing explosion-proof steel forks cannot lock the neck of criminals, thus allowing them to escape. It includes a mounting base 1, with arc-shaped forks 2 rotatably connected to both ends. A lifting structure 3 is located at the bottom of the mounting base 1, and a locking structure 5 is located inside the mounting base 1. The lifting structure 3 drives the mounting base 1 to rise and fall, while the locking structure 5 controls the locking or unlocking of the arc-shaped forks 2.

[0025] Combination Figure 1 and Figure 3 In the embodiments of this utility model, the inner sides of the two sets of arc-shaped forks 2 are fixedly connected with rubber pads 21.

[0026] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the locking structure 5 includes a second motor 51, which is fixedly installed on the inner bottom wall of the mounting base 1. A rotating shaft 52 is fixedly installed on the power output end of the second motor 51. A large gear 53 is installed on the end of the rotating shaft 52 away from the second motor 51. Vertical plates 54 are installed on both ends of the inner top wall of the mounting base 1. Rotating columns 55 are rotatably connected inside the two sets of vertical plates 54. A small gear 56 is fixedly sleeved on the outer side of the rotating column 55 for meshing with the large gear 53.

[0027] Combination Figure 1 and Figure 2In an embodiment of this utility model, the locking structure 5 further includes two sets of bevel gears 57, which are respectively fixedly installed at both ends of the rotating column 55. Both ends of the mounting base 1 are rotatably connected to the connecting shafts 59. The outer sides of the two sets of connecting shafts 59 are fixedly sleeved with bevel gears 58 for meshing with bevel gears 57. The two sets of connecting shafts 59 extend to the outside of the mounting base 1 and are fixedly sleeved with the two sets of arc-shaped forks 2.

[0028] In use, the second motor 51 is started. When the second motor 51 is working, it drives the large gear 53 to rotate via the rotating shaft 52. Since the large gear 53 is meshed with the small gear 56, the rotation of the large gear 53 drives the small gear 56 to rotate. The rotation of the small gear 56 drives the rotating column 55 to rotate. The rotation of the rotating column 55 drives the two sets of bevel gears 57 to rotate. Since the first bevel gear 57 is meshed with the second bevel gear 58, the rotation of the first bevel gear 57 drives the second bevel gear 58 to rotate. The rotation of the second bevel gear 58 drives the two sets of connecting shafts 59 to rotate, thereby enabling the two... The connecting shaft 59 drives the two arc-shaped forks 2 to rotate relative to each other, locking the neck of the criminal and preventing the criminal from breaking free and escaping. Because the large gear 53 and the small gear 56, as well as the bevel gear 1 57 and the bevel gear 2 58 have a self-locking function, the bevel gear 2 58 cannot rotate after the rotating column 55 stops rotating, thus fixing the position of the two sets of arc-shaped forks 2. At the same time, a rubber pad 21 is set on the inner side of the arc-shaped fork 2. The rubber pad 21 directly contacts the neck of the criminal, which can effectively protect the neck of the criminal and prevent accidents.

[0029] Example 2: Reference Figure 1 and Figure 3 To address the issue that existing explosion-proof steel forks are difficult to deploy quickly in emergency situations, significantly limiting their usability, a lifting structure 3 is proposed. This structure includes a housing 31. A horizontal plate 32 is fixedly installed at the lower end of the housing 31. A threaded column 33 is rotatably connected to the top of the horizontal plate 32. A first motor 34 is fixedly installed at the bottom of the horizontal plate 32 to drive the threaded column 33 to rotate. A movable sleeve 35 is screwed to the outer side of the threaded column 33, and the top of the movable sleeve 35 is fixedly connected to the bottom of the mounting base 1. Sliding rods 351 are fixedly connected to the bottom of both sides of the movable sleeve 35. Sliding grooves 311 are provided on both sides of the housing 31 for sliding engagement with the sliding rods 351.

[0030] When the overall length of the explosion-proof steel fork needs to be adjusted, the first motor 34 is started. When the first motor 34 is working, it drives the threaded column 33 to rotate. Since the threaded column 33 is threadedly connected to the movable sleeve 35, the rotation of the threaded column 33 drives the movable sleeve 35 to move upward. While the movable sleeve 35 moves, it drives the sliding rod 351 to slide inside the slide groove 311, thereby restraining the movable sleeve 35 and making the movable sleeve 35 always move vertically. This allows the overall length of the explosion-proof steel fork to be quickly adjusted to the required length, improving the flexibility of the explosion-proof steel fork during use.

[0031] Example 3: Reference Figure 1 and Figure 3 To address the issue of slippage during the handling of the handle 4 by security personnel, a handle 4 is fixed to the bottom of the outer shell 31, and several rubber protrusions 41 are fixedly connected to the inner bottom wall of the handle 4.

[0032] During use, the explosion-proof steel fork allows security personnel to hold the handle at four points, making it convenient for them to use. The rubber protrusions 41 directly contact the hand, increasing the friction between the handle and the hand and preventing the fork from slipping.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
