Description

Technical Field

[0001] This utility model relates to the field of mechanical connectors, specifically to a pin connection assembly. Background Technology

[0002] In the field of mechanical connections, pin connections are a commonly used component connection method and are widely used in various mechanical equipment. Traditional pin connection positioning methods are relatively simple, relying only on simple shaft-hole fits. When subjected to complex working conditions or large external forces, problems such as axial movement and circumferential rotation are prone to occur, resulting in poor connection stability and affecting the normal operation of the equipment. Moreover, its adaptability to parts of different shapes is limited, making it difficult to meet diverse connection needs and lacking versatility.

[0003] Based on the above, this utility model proposes a pin connection assembly that can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a pin connection assembly.

[0005] This utility model is achieved through the following technical solution:

[0006] A pin connection assembly includes a shaft body and a shaft head; the top of the shaft body is fixedly connected to one end of the lower surface of the shaft head, and the top of the shaft head has a groove with a waist-shaped cross-section; the top two sides of the groove have shaft holes facing each other, and the shaft holes penetrate the sidewall of the groove; the bottom of the groove has a pin hole at the end away from the shaft body, and the pin hole penetrates the bottom wall of the groove.

[0007] According to the above technical solution, as a further preferred technical solution, at least two annular grooves are provided at the end of the shaft away from the shaft head.

[0008] According to the above technical solution, as a further preferred technical solution, a retaining ring is installed inside the annular groove.

[0009] According to the above technical solution, as a further preferred technical solution, one side of the shaft head is provided with an arc-shaped side surface, and the opposite side is provided with a vertical plane.

[0010] According to the above technical solution, as a further preferred technical solution, the bottom of the vertical plane is provided with an outwardly extending protrusion, and the cross-section of the protrusion is semi-circular.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] This utility model provides a pin connection assembly. By providing a pin head, the pin holes on both sides of the top of the pin head can be used to insert other shaft parts, achieving hinged connections between components and allowing relative rotation. The pin hole at the bottom of the groove can be used to insert positioning or fastening elements such as pins, further securing the connected components and preventing radial rotation, thereby improving the stability and reliability of the connection. By providing an annular groove on the shaft body, and installing a retaining spring within the annular groove, axial movement of the shaft body within the mating hole or groove is prevented, confining the shaft body to a specific position and ensuring that the pin connection assembly will not shift due to axial force during operation, thus improving the stability of the connection.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0016] A pin connection assembly includes a shaft body 1 and a shaft head 2; the top of the shaft body 1 is fixedly connected to one end of the lower surface of the shaft head 2, and the top of the shaft head 2 is provided with a groove 21, the cross-section of the groove 21 being waist-shaped; the top two sides of the groove 21 are respectively provided with shaft holes 22 facing each other, the shaft holes 22 penetrating the sidewall of the groove 21; the bottom end of the groove 21 away from the shaft body 1 is provided with a pin hole 23, the pin hole 23 penetrating the bottom wall of the groove 21.

[0017] This utility model provides a shaft head 2, with shaft holes 22 on both sides of the top of the shaft head 2, which can be used to insert other shaft parts to achieve hinge between the parts, allowing the connected parts to rotate relative to each other; the pin hole at the bottom of the groove can be used to insert positioning or fastening elements such as pins to further fix the connected parts and prevent radial rotation, thereby improving the stability and reliability of the connection.

[0018] Furthermore, in another embodiment, the end of the shaft 1 away from the shaft head 2 has at least two annular grooves 11. Furthermore, in another embodiment, a retaining ring 3 is installed inside the annular groove 11.

[0019] By setting an annular groove 11 and installing a retaining ring 3 inside the annular groove 11, the shaft 1 can be prevented from axially moving within the hole or groove that it mates with, thus restricting the shaft to a specific position and ensuring that the pin connection assembly will not be displaced by axial force during operation, thereby improving the stability of the connection.

[0020] Furthermore, in another embodiment, the shaft head 2 has an arc-shaped side surface 24 on one side and a vertical plane 25 on the opposite side.
