Abstract
Description
Technical Field
[0001] This utility model relates to the field of pin technology, specifically a pin structure that can be automatically positioned. Background Technology
[0002] A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is primarily used at the hinge points of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. The difference between a pin and a shaft is that there are many types of pins, including dowel pins, tapered pins, spring pins, and shafts. Most pins are used for fixed connections, while shafts are commonly used for movable hinge points.
[0003] Existing patent CN218817452U proposes an automatic limiting pin structure, including a pin body. The top of the pin body is integrally formed with a pin disc. Through the cooperation of a threaded rod, a threaded sleeve, a connecting block, a rotating rod, and a limiting rod, the limiting rod is driven to move outward, automatically limiting the two sides of the bottom of the pin body to prevent the pin body from loosening or falling off from the connection position. The user pre-inserts the pin body into the hinge position of the connector.
[0004] However, this pin structure still has some defects. During use, it is not convenient to adjust the position of the limit rod. Therefore, when used in different environments, the limit rod is not convenient to clamp the connecting structure, which can easily lead to loosening of the connection and poor limiting effect.
[0005] Based on this, an automatically positioning pin structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0008] An automatically positioning pin structure includes a pin body, a connecting plate installed on one side of the pin body, a support ring installed in the middle of one side of the connecting plate, and two sliding grooves opened on both sides inside the pin body.
[0009] The support ring is internally threaded with an adjustment assembly;
[0010] A connecting component is slidably connected to the inside left side of the sliding groove. The connecting component includes a movable block, a connecting ring is installed on one side of the movable block, and two fixing grooves are opened on the upper and lower sides of the connecting ring.
[0011] Two limiting components are installed on both sides of one side of the connecting ring.

[0031] A connecting component is slidably connected to the inside left side of the sliding groove 13. The connecting component includes a moving block 31. A connecting ring 3 is installed on one side of the moving block 31. Two fixing grooves 32 are opened on the upper and lower sides of the connecting ring 3.
[0032] Two limiting components are installed on both sides of one side of the connecting ring 3.
[0033] In this embodiment, the support ring 12 is supported by the connecting plate 11, and the support ring 12 is threadedly connected to the adjustment component. The moving block 31 is slidably connected in the sliding groove 13. There is a connecting ring 3 between the two moving blocks 31. The connecting ring 3 is slidably connected to the outside of the threaded rod 2. The pin is limited by the limiting component, which improves the practicality and convenience of the device. The position of the connecting component is adjusted by the adjusting component so as to drive the connecting ring 3 to move inside the pin body 1.
[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, two opening slots 14 are provided on the upper and lower sides of the main body of the pin shaft 1. The opening slots 14 facilitate the passage of the limiting plate 36 and allow the limiting plate 36 to slide inside.
[0035] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjustment assembly includes a threaded rod 2, which is threadedly connected to the inside of the support ring 12. A rotating handle 21 is installed on one side of the threaded rod 2, and a connecting block 22 is rotatably connected to the other side of the threaded rod 2. By rotating the rotating handle 21, the threaded rod 2 is driven to rotate, thereby causing the threaded rod 2 to rotate on one side of the connecting block 22.
[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, the outer thread of the threaded rod 2 is connected to a support assembly, which supports the connecting assembly.
[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, the support assembly includes a movable ring 23, which is threaded to the outside of the threaded rod 2. Two sliding holes 24 are opened on both sides of the inside of the movable ring 23. Two sliding blocks 25 are installed on both sides of the movable ring 23. A support spring 26 is installed on one side of the movable ring 23. The movement of the movable ring 23 is limited by the sliding blocks 25 on both sides of the movable ring 23 sliding inside the sliding groove 13.
[0038] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the limiting component includes a limiting rod 33, which is installed on both sides of one side of the connecting ring 3. The limiting rod 33 is slidably connected inside the sliding hole 24. A limiting block 34 is installed on one side of the limiting rod 33. The moving ring 23 is limited by the limiting rod 33 and the limiting block 34.
[0039] In one embodiment, such as Figure 1 and Figure 4 As shown, a shielding component is installed inside the fixing groove 32 to limit the pin shaft.
[0040] In one embodiment, such as Figure 1 and Figure 4As shown, the shielding assembly includes a return spring 35, which is installed inside the fixing groove 32. A limiting plate 36 is installed on the top of the return spring 35. The limiting plate 36 is slidably connected inside the fixing groove 32. The return spring 35 pushes the limiting plate 36 upward, thereby limiting the pin shaft through the limiting plate 36.
[0041] The above embodiment discloses an automatically positioning pin structure, wherein the pin body 1 is inserted into the connector, and the rotating handle 21 drives the threaded rod 2 to rotate. Through the threaded connection between the threaded rod 2 and the moving ring 23, and the sliding blocks 25 on both sides of the moving ring 23 sliding and limiting within the sliding groove 13, the moving ring 23 is driven to move to the right inside the pin body 1. Through the sliding of the limiting rod 33 within the sliding hole 24, and the support and limiting of the moving ring 23 by the limiting block 34, the connecting ring 3 is driven to move inside the pin body 1. Rod 33 slides inside sliding hole 24, and moving block 31 slides inside sliding groove 13, thereby limiting the movement of connecting ring 3. When connecting ring 3 moves to opening groove 14, limiting plate 36 is pushed upward by the automatic rebound of return spring 35. Limiting plate 36 passes through opening groove 14 to limit the pin body 1. The rebound of support spring 26 drives limiting plate 36 to clamp connecting parts, improving the stability and convenience of the device. Rotating handle 21 makes it easy to adjust the tightness of clamping of limiting plate 36, improving the practicality of the structure.
