Description

Technical Field

[0001] This utility model relates to the field of pin technology, specifically to a wear-resistant and anti-detachment pin. Background Technology

[0002] A pin is a standardized fastener that can be used for static fixed connection or for relative movement with the connected parts. It is mainly used at the hinge joint of two parts to form a hinge connection.

[0003] Pins are usually locked with cotter pins. The pin cap fits against the side wall of the workpiece, but the cotter pin cannot fit against the workpiece. During use, workpiece vibration can easily cause the cotter pin to resonate, making it easy for the cotter pin to fall off the pin, affecting the pin's tightness and stability, and reducing its performance. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by designing an anti-detachment and wear-resistant pin.

A fixed through groove is provided on the other side of the pin body, and a positioning element is provided in the fixed through groove, which is movably disposed in the fixed through groove; A positioning component, which is used to position a positioning element, is disposed on the pin body.

[0006] Furthermore, the positioning component includes a rotating shaft, a vertical circular groove is provided in the body of the pin shaft, the bottom end of the vertical circular groove is connected to a fixed through groove, the rotating shaft is located in the vertical circular groove, the bottom end of the rotating shaft extends out of the vertical circular groove and is located in the fixed through groove, a threaded rod is fixedly connected to the bottom end of the rotating shaft, a guide slider is provided in the fixed through groove, the guide slider is threadedly engaged with the threaded rod, a hinge component one is fixedly connected to one side of the guide slider, a hinge component two is fixedly connected to the side wall of the positioning component, the hinge component two is hinged to the hinge component one through a hinge shaft, and a U-shaped opening is provided on one side of the positioning component.

[0007] Furthermore, the positioning component also includes an adjusting cap, the surface of which is provided with a fixing round hole, the top end of which is connected to the fixing round hole, the adjusting cap is fixedly connected to the top end of the rotating shaft, the adjusting cap is located inside the fixing round hole, and the rotating shaft is provided with a locking groove at one end of the fixing through groove, and a locking pad is connected to the locking groove.

[0008] Furthermore, the length of the positioning element is less than the length of the fixed through groove, and the surface of the positioning element is arc-shaped and matches the surface of the pin body.

[0009] Furthermore, the outer wall of the pin body is provided with a wear-resistant layer, and the wear-resistant layer is provided with anti-corrosion paint.

[0010] The wear-resistant layer improves the wear resistance of the pin and reduces the wear rate, while the anti-corrosion paint prevents the pin from corroding and rusting, thus extending its service life.

[0011] Furthermore, the adjusting cap, rotating shaft, and threaded rod are integrally formed, and the surface of the adjusting cap is provided with a cross screw groove.

[0012] The one-piece molding process improves strength and prevents breakage. The adjustment cap is turned by screwing the cross screw groove to rotate the rotating shaft, making operation convenient.

[0013] Compared with existing technologies, this technical solution has the following beneficial effects: 1. The rotating shaft drives the threaded rod to rotate and drive the guide slider to rise and fall. After adjusting the positioning part to a horizontal state, the positioning part rises and fits against the side wall of the workpiece. The positioning part and the shaft cap engage and position the pin body. There is no need to use cotter pins, which can prevent cotter pins from falling off due to vibration and prevent the pin from falling out of the pin hole. This improves the tightness of the pin fixation, improves the stability, and improves the use effect. 2. Rotate the rotating shaft by adjusting the cap, insert the rotating shaft into the vertical circular groove, and then insert the locking shim into the locking groove to prevent the rotating shaft from moving out of the vertical circular groove. This facilitates the disassembly and assembly of the rotating shaft and improves work efficiency. Attached Figure Description

The rotating shaft 501 is provided with a locking groove 8 at one end of the fixing through groove 3. A locking pad 9 is connected to the locking groove 8.

[0028] The rotating shaft 501 is rotated by adjusting the cap 6 and inserted into the vertical circular groove 502. Then, the locking shim 9 is inserted into the locking groove 8 to prevent the rotating shaft 501 from moving out of the vertical circular groove 502. This makes it easier to disassemble and assemble the rotating shaft 501 and improves work efficiency.

[0029] Refer to the instruction manual appendix Figure 4 The outer wall of the pin body 1 is provided with a wear-resistant layer 10, and the wear-resistant layer 10 is provided with anti-corrosion paint 11.
