[0002] A security protection fork is a tool specifically designed to enhance the safety of security personnel and is usually used for defending against and controlling violent behavior. It usually has multiple fork-shaped tips for preventing or stopping attacks, and has a strengthened structure to cope with intense conflicts. The protection fork may be equipped with strong materials and protective designs to improve durability and operating safety.

[0003] For example, the Chinese utility model patent (CN218973322U) discloses a security protection fork, which records: "By rotating the round tube, the overall length of the protection fork can be adjusted; when using the protection fork, the hands of the police officers respectively hold the handle one and the handle two, which is convenient for both hands to exert force. At the same time, the rubber anti-slip layers on the surfaces of the handle one and the handle two can prevent the protection fork from slipping during use, so that the control is more stable", and also records the technical problem of "the existing method for adjusting the length of the security protection fork is not convenient enough, and the control is not stable enough during use".

[0004] To sum up, it can be seen that in the prior art, the overall length of the protection fork is adjusted by rotating the threaded rod to drive the sliding block to move. However, this method has the following technical problems: in this device, when an emergency occurs and the protection fork needs to be used, continuously rotating the threaded rod to adjust the overall length of the protection fork is time-consuming, which will prevent the security personnel from taking actions in time, and the practicability of the device is low. Therefore, this application proposes a new type of security protection fork to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model

[0005] Based on this, in view of the above technical problems, it is necessary to provide a new type of security protection fork. By pulling the sliding rod and the support shell to two opposite positions, the sliding rod can slide in the support shell, and the overall length of the sliding rod and the support shell will increase accordingly. After the length between the support shell and the sliding rod reaches the maximum, the sliding rod can be restricted from entering the support shell under the cooperation of the limiting claw and the fixed tooth group, that is, the position of the sliding rod is restricted. Then, actions can be taken as soon as possible. The method of adjusting the overall length of this device is simple and fast, which is convenient for dealing with emergencies and improves the practicability of the device.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A new type of security protection fork, which is applied to security.

[0008] The novel security protection fork specifically includes:

[0009] A support shell, a fixing belt is fixedly connected to the bottom of the support shell, an adjusting mechanism is arranged on the support shell, and a stabilizing component is arranged on the support shell;

[0010] The adjusting mechanism includes a sliding rod, a rotating shaft, a driving component, a limiting component, and a close-fitting component. The inner wall of the support shell is slidably connected with a sliding rod, and the inner wall of the support shell is rotatably connected with a rotating shaft.

[0011] As a preferred embodiment of the novel security protection fork provided by the present invention, the driving component includes a rotating shell. One end of the rotating shaft is fixedly connected with the rotating shell, the rotating shell is rotatably connected to the inner wall of the support shell, and a triangular block is fixedly connected to the inner wall of the rotating shell.

[0012] As a preferred embodiment of the novel security protection fork provided by the present invention, the limiting component includes a limiting claw. A limiting claw is fixedly connected to the outer wall of the rotating shaft near the middle, and a fixed tooth group adapted to the limiting claw is fixedly connected to the inner wall of the sliding rod.

[0013] As a preferred embodiment of the novel security protection fork provided by the present invention, the close-fitting component includes a torsion spring. Torsion springs are respectively sleeved on the outside of the rotating shaft on the front and rear sides of the limiting claw, and the two ends of the torsion spring are respectively fixedly connected to the outer wall of the limiting claw and the inner wall of the support shell.

[0014] As a preferred embodiment of the novel security protection fork provided by the present invention, the stabilizing component includes a mounting plate. The top end of the sliding rod is fixedly connected with the mounting plate, the mounting plate is detachably connected with a connecting block through bolts, and an arc-shaped fork is fixedly connected to the inner wall of the connecting block.

[0015] As a preferred embodiment of the novel security protection fork provided by the present invention, the stabilizing component further includes a protection plate. Protection plates are respectively fixedly connected to the left and right sides of the mounting plate.

[0018] When the overall length of the support shell and the sliding rod of the novel security protection fork provided by the present utility model needs to be shortened, a triangular key adapted to the device needs to be inserted into the rotating shell and rotated. Only under the cooperation of the triangular block can the rotating shaft be driven to rotate accordingly, and then the torsion spring deforms, causing the limiting claw to leave the fixed tooth group. Then the sliding rod can be slid into the interior of the support shell, preventing the criminal from adjusting the overall length of the support shell and the sliding rod during the process of security personnel using the device to control the criminal, thus improving the security of the device.

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As described in the background art, in this device, when it is necessary to use the protection fork in case of an emergency, continuously rotating the threaded rod to adjust the overall length of the protection fork is time-consuming, which will prevent the security personnel from taking timely actions, and the practicability of the device is low.

[0030] To solve this technical problem, the present utility model provides a new security protection fork, which is applied to security.

[0031] Specifically, please refer to Figures 1-4 , the new security protection fork specifically includes:

[0032] Support shell 1, the bottom of the support shell 1 is fixedly connected with a fixed belt 2, an adjustment mechanism 3 is arranged on the support shell 1, and a stabilizing component 4 is arranged on the support shell 1;

[0033] The adjustment mechanism 3 includes a sliding rod 5, a rotating shaft 7, a driving component, a restricting component, and a close-fitting component. The inner wall of the support shell 1 is slidably connected with a sliding rod 5, and the inner wall of the support shell 1 is rotatably connected with a rotating shaft 7.

[0034] The novel security protection fork provided by the utility model can make the sliding rod 5 slide in the support shell 1 by pulling the sliding rod 5 and the support shell 1 to two opposite positions, so that the overall length of the sliding rod 5 and the support shell 1 increases accordingly. After the length between the support shell 1 and the sliding rod 5 increases to the maximum, the sliding rod 5 can be restricted from entering the support shell 1 under the cooperation of the limiting claw 10 and the fixed tooth group 6, that is, the position of the sliding rod 5 is restricted. Then, actions can be taken as soon as possible. The placement of the overall length of this adjustment device is simple and fast, so as to cope with emergencies and improve the practicability of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings.

[0036] Embodiment 1:

[0037] Please refer to Figures 2-4 , a novel security protection fork, which includes:

[0038] The driving component includes a rotating shell 8. One end of the rotating shaft 7 is fixedly connected with the rotating shell 8. The rotating shell 8 is rotatably connected to the inner wall of the support shell 1. The inner wall of the rotating shell 8 is fixedly connected with a triangular block 9. Insert the adapted triangular key into the rotating shell 8 and rotate the triangular key to drive the rotating shell 8 to rotate accordingly, avoiding the situation that the rotating shell 8 rotates due to external force during the use of the device, and improving the stability of the device.

[0039] The limiting component includes a limiting claw 10. The outer wall of the rotating shaft 7 and near the middle is fixedly connected with the limiting claw 10. The inner wall of the sliding rod 5 is fixedly connected with a fixed tooth group 6 adapted to the limiting claw 10. The cooperation of the limiting claw 10 and the fixed tooth group 6 can limit the position of the sliding rod 5. When the limiting claw 10 is closely attached to the outside of the fixed tooth group 6, the sliding rod 5 cannot slide into the support shell 1.

[0040] The close - fitting component includes a torsion spring 11. Torsion springs 11 are respectively sleeved on the outside of the rotating shaft 7 and on the front and rear sides of the limiting claw 10. The torsion spring 11 can make the limiting claw 10 have a tendency to keep closely attached to the outside of the fixed tooth group 6. The two ends of the torsion spring 11 are respectively fixedly connected to the outer wall of the limiting claw 10 and the inner wall of the support shell 1.

[0041] Through the above structural design, when the device is unfolded, the sliding rod 5 and the support shell 1 are pulled to two opposite positions, so that the sliding rod 5 can slide inside the support shell 1, increasing the overall length of the sliding rod 5 and the support shell 1. After the length between the support shell 1 and the sliding rod 5 increases to the maximum, the position of the sliding rod 5 can be restricted by the cooperation of the limiting claw 10 and the fixed tooth group 6, that is, the sliding rod 5 cannot enter the support shell 1. When it is necessary to shorten the device, a triangular key adapted to the device is inserted into the rotating shell 8 and rotated. Rotating the triangular key can drive the rotating shell 8 to rotate through the triangular block 9, and then drive the rotating shaft 7 to rotate accordingly, so that the torsion spring 11 deforms accordingly, causing the limiting claw 10 to leave the fixed tooth group 6. Then, the sliding rod 5 can be slid into the interior of the support shell 1. After the sliding rod 5 is retracted into the support shell 1 to an appropriate degree, the triangular key is removed immediately. Under the action of the elastic force of the torsion spring 11, the appropriate limiting claw 10 will closely adhere to the outside of the fixed tooth group 6 again.

[0042] Embodiment 2:

[0043] The new security protection fork provided in Embodiment 1 is further optimized. Specifically, as Figures 2-4 shown, the stabilizing assembly 4 includes a mounting plate 12. The top end of the sliding rod 5 is fixedly connected to the mounting plate 12. The mounting plate 12 is detachably connected to a connecting block 13 by bolts. Removing the bolts can replace the arc-shaped fork 14, avoiding the situation that the whole device cannot be used due to the damage of the arc-shaped fork 14. The inner wall of the connecting block 13 is fixedly connected to an arc-shaped fork 14.

[0044] The stabilizing assembly 4 further includes a protection plate 15. The left and right sides of the mounting plate 12 are respectively fixedly connected to the protection plate 15. The bottom parts of the two protection plates 15 are respectively fixedly connected to a plurality of first stabilizing rods 16. The ends of the plurality of first stabilizing rods 16 far from the protection plate 15 are fixedly connected to the outer wall of the sliding rod 5. The top parts of the two protection plates 15 are respectively fixedly connected to a plurality of second stabilizing rods 17. The ends of the plurality of second stabilizing rods 17 far from the protection plate 15 are respectively closely attached to the outer wall of the arc-shaped fork 14. The first stabilizing rods 16 and the second stabilizing rods 17 can improve the strength of the arc-shaped fork 14 to resist external forces.

[0045] Through the above structural design, by removing the corresponding bolts on the mounting plate 12 and the connecting block 13, the mounting plate 12 and the connecting block 13 can be separated, and then the arc-shaped fork 14 can be separated from the second stabilizing rod 17, and the connecting block 13 and the arc-shaped fork 14 can be replaced. When the arc-shaped fork 14 forks towards the criminal, the first stabilizing rods 16, the protection plate 15 and the second stabilizing rods 17 will support the arc-shaped fork 14.
