Description

Technical Field

[0001] This utility model relates to the field of pin technology, and in particular to a 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. Pins are usually locked with cotter pins, which are reliable and easy to disassemble.

[0003] Pins generally have a simple, cylindrical structure. However, during use, the end walls of the pins are easily worn and damaged, resulting in poor safety and stability during subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a pin.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pin includes a pin post, a pin hole is provided at the center side wall of the pin post, a side hole and an orifice are provided on the left side wall of the pin post, and a reservoir for adding lubricating fluid is provided on the right side wall of the pin post.

[0007] Preferably, the pin hole and the side hole are perpendicular to each other.

[0008] Preferably, the end wall of the pin near the storage cavity has a side opening, the size of which is larger than the size of the storage cavity.

[0009] Preferably, the side opening and the storage cavity are connected, and both the side opening and the storage cavity are circular in shape.

[0010] Preferably, the side opening is internally threaded with a side disc, which is disc-shaped.

[0011] Preferably, a sponge strip is adhered to the right wall of the side plate, and a sponge block is adhered to the left wall of the side plate, with the sponge strip and sponge block being bonded together.

[0012] This utility model has at least the following beneficial effects:

[0013] Lubricating oil can be added to the reservoir. A side plate is screwed into the side opening to seal the reservoir. The sponge strip is cylindrical and extends into the reservoir to absorb the lubricating oil and transfer it to the sponge block. Both the sponge strip and the sponge block are made of sponge material, which can slowly absorb the lubricating oil and seep out along the sponge block, providing simple lubrication and protection to the end wall of the pin, preventing wear and damage to the pin, and facilitating the safe use of the pin.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a pin shaft:

[0022] like Figure 1-4 As shown, a pin includes a pin 1, a pin hole 2 is provided at the center side wall of the pin 1, a side hole 3 and an orifice 4 are provided on the left side wall of the pin 1, and a storage cavity 5 for adding lubricating fluid is provided on the right side wall of the pin 1.

[0023] The pin hole 2 and the side hole 3 are perpendicular to each other;

[0024] A side opening 6 is provided on the end wall of the pin 1 near the storage cavity 5. The size of the side opening 6 is larger than the size of the storage cavity 5. The side opening 6 and the storage cavity 5 are connected. Both the side opening 6 and the storage cavity 5 are circular.

[0025] Side plate 7 is connected to the internal thread of side opening 6. Side plate 7 is disc-shaped. Sponge strip 8 is glued to the right wall of side plate 7 and sponge block 9 is glued to the left wall of side plate 7. Sponge strip 8 and sponge block 9 are glued together.

[0026] Working principle:

[0027] The pin hole 2 at pin 1 is located in the middle area. A side hole 3 and an opening 4 are provided on the left side of pin 1. The areas on both sides of pin 1 can be hardened during manufacturing, while the middle area does not require hardening.

[0028] There is no need to customize shielding copper tube plungers because of the different sizes of oil holes for each pin.

[0029] This can effectively prevent the oil hole opening from being inadequately shielded, resulting in a hardened layer and premature cracking of the opening.

[0030] Meanwhile, segmented quenching can effectively avoid the problems of copper tube leakage leading to pin failure and difficulty in removal after processing, which increases the overall processing cycle.

[0031] After processing, a storage cavity 5 and a side opening 6 are drilled out on the right wall of the pin 1. Lubricating oil can be added to the storage cavity 5. A side plate 7 is screwed into the side opening 6 to seal the storage cavity 5. The sponge strip 8 is a cylindrical structure that extends into the storage cavity 5 to absorb the lubricating oil and transfer it to the sponge block 9. Both the sponge strip 8 and the sponge block 9 are made of sponge material, which can slowly absorb the lubricating oil and seep out along the sponge block 9, providing simple lubrication and protection for the end wall of the pin 1, preventing wear and damage to the pin 1, so as to facilitate the safe use of the pin 1.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
