[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] like Figure 1-7 As shown, this is an embodiment of the present utility model. To achieve the above objectives, the present utility model provides the following technical solution: an anti-loosening pin, including a pin seat integrally formed from a base plate 1 and a shell 2, and an adapter seat provided on one side of the pin seat. The adapter seat includes an integrally formed fixing seat 4 and a limiting frame 41. The pin seat and the adapter seat form a pin assembly. The internal cavities of the base plate 1 and the shell 2 are connected. Two arch frames 11 are provided at the top of the base plate 1 on the front side of the shell 2. The two arch frames 11 are symmetrically located on both sides of the pin rod 3 to limit the pin rod 3 and ensure that the pin rod 3 can move linearly.

[0022] Furthermore, a movable groove 21 is provided on the top of the housing 2, and two reinforcing plates 22 distributed on both sides of the movable groove 21 are fixedly provided on the inner wall of the cavity of the housing 2. Two sliders 211 are slidably connected in the movable groove 21. The top of the two sliders 211 is fixedly connected to the same handle 23 for hand movement. During the movement of the handle 23, the two sliders 211 are moved synchronously. One of the sliders 211 has a pin 3 extending to the outside of the housing 2 at its bottom end. The other end of the pin 3 passes through the limiting frame 41. The two sliders 211 and the handle 23 form an integrated structure. Therefore, when installing the handle 23, the two sliders 211 are passed through one end of the movable groove 21 and connected to the housing 2. Then, the handle 23 is slid to move the two sliders 211 synchronously to a position close to the arch frame 11. After that, the pin 3 is inserted into the housing 2 between the two arch frames 11.

[0023] Both sliders 211 are I-shaped structures, and the distance between the two sliders 211 is less than the length of the moving groove 21. The bottom end of the pin rod 3 is provided with a mounting groove 31 on one side near the slider 211. A connecting plate 32 is fixedly connected to the mounting groove 31 by bolts. The other end of the connecting plate 32 is fixedly connected to a slider 211 nearby by bolts. When the handle 23 is moved, it can drive the pin rod 3 to make linear displacement and make one end of the pin rod 3 pass through the limit frame 41 to achieve the locking effect of the pin.

[0024] Furthermore, a turntable 212 is provided at the bottom of another slider 211. Two stabilizing rods 213 are fixedly connected to the outer surface of the turntable 212. The side of the reinforcing plate 22 near the slider 211 is a rack-shaped structure. The rack of the rack-shaped structure is inclined to facilitate the adaptation and engagement with the deflecting stabilizing rods 213. The two stabilizing rods 213 are the same in shape and size and face opposite directions. The shape of one end of the two stabilizing rods 213 is adapted to the shape of the tooth groove of the reinforcing plate 22. When one end of the two stabilizing rods 213 extends outward, they can be engaged in the tooth groove of the reinforcing plate 22.

[0025] Furthermore, one end of the moving groove 21 penetrates the entire rear end face of the housing 2. The side view of the moving groove 21 is a straight line and parallel to the top of the housing 2. A vertical cylindrical hole is opened at the center of the slider 211. The top of the cylindrical hole penetrates the inner wall of the handle 23, and a screw 214 is threaded into the cylindrical hole. The top of the screw 214 is fixedly connected to a knob 231 located inside the handle 23. The bottom of the screw 214 is fixedly connected to the turntable 212. By appropriately rotating the knob 231, the screw 214 is driven. 4. Rotating synchronously with turntable 212, the rotation of turntable 212 can cause the two stabilizer rods 213 to deflect to a certain extent, so that the other end of stabilizer rod 213 is obliquely inserted into the tooth groove of reinforcing plate 22, thereby achieving the effect of positioning slider 211, and indirectly positioning pin rod 3, ensuring that pin rod 3 has higher stability after being connected to limit frame 41. Since the screw 214 and slider 211 are connected by threads, the screw 214 will not rotate when not subjected to external force, further ensuring the stability of pin rod 3.

[0026] In the above embodiment, when the pin 3 is inserted into the limiting frame 41, the two sliders 211 are moved by the handle 23. One slider 211 moves the pin 3 into the limiting frame 41 via the connecting plate 32. At the same time, the other slider 211 moves synchronously. Then, the knob 231 located inside the handle 23 is rotated appropriately. The knob 231 drives the screw 214 and the turntable 212 to rotate synchronously. The rotation of the turntable 212 can cause the two stabilizing rods 213 to deflect to a certain extent, so that the other end of the stabilizing rod 213 is obliquely inserted into the tooth groove of the reinforcing plate 22, thereby achieving the effect of positioning the slider 211, and indirectly positioning the pin. The rod 3 is positioned to ensure greater stability after the pin rod 3 is connected to the limit frame 41. Since the screw 214 and the slider 211 are connected by a thread, the screw 214 will not rotate when it is not subjected to external force, which further ensures the stability of the pin rod 3 and achieves the effect of preventing the pin from loosening. When it is necessary to open the pin structure, firstly, the reverse knob 231 is turned. The knob 231 drives the two stabilizing rods 213 to perform a reset movement, thereby disengaging them from the tooth grooves of the reinforcing plates 22 on both sides. At this time, the movement of the slider 211 is no longer restricted by the tooth grooves of the reinforcing plates 22. Then, the handle 23 is held to drive the two sliders 211 to move so that the pin rod 3 is moved out of the limit frame 41.
