Description

Technical Field

[0001] This utility model relates to the field of pin technology, and in particular to a lubrication structure for pin maintenance. 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 joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. During maintenance, pins are lubricated; this lubrication structure is designed for this purpose.

[0003] When lubricating a pin, external tools are needed, such as a spray can containing lubricant to spray lubricant onto the pin, or a sponge soaked in lubricant to apply lubricant to the pin. Because the surface of the pin is curved and has a large area, the pin needs to be rotated repeatedly for lubrication. The whole process is cumbersome, complicated and not fast or convenient. Utility Model Content

[0004] The purpose of this invention is to provide a lubrication structure for the maintenance of pins.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A lubrication structure for pin maintenance includes a storage tank and a cavity inside the storage tank for storing lubricating fluid. A glass plate for viewing the cavity is installed on the front wall of the storage tank. A retainer is installed near the top of the cavity of the storage tank. A cover adapted to the size of the storage tank is placed on the upper end of the retainer. An opening is provided through the inside of the cover and the retainer. A sponge sleeve is installed on the inner wall of the opening. A passage for the pin to pass through is provided inside the sponge sleeve.

[0007] Preferably, the passage includes a middle opening, a high opening, and a low opening, and seven sponge sleeves are provided. The middle opening is provided in the four sponge sleeves near the left and right sides of the cover, the high opening is provided in the two sponge sleeves near the front and rear sides of the cover, and the low opening is provided in the sponge sleeve at the center end wall of the cover.

[0008] Preferably, there are six middle openings and six high openings, and the middle openings and high openings are arranged in a ring about the center of the cover.

[0009] Preferably, the storage bucket and the glass plate are bonded together, and the bucket cavity and the card holder are interlocked.

[0010] Preferably, the card holder and the cover are fixedly connected, and the card holder, the cover, and the storage bin are all disc-shaped.

[0011] Preferably, the top of the opening is shaped like an inverted frustum and the bottom is cylindrical. The end wall of the opening is bonded to the sponge sleeve. The pin passes through the sponge sleeve and through the opening. Excess lubricant on the end wall of the pin is scraped off and seeps down along the top of the opening.

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

[0013] 1. Four medium openings, two high openings, and one low opening are used to insert and pass through pins of different sizes, adapting to different sizes of pins and making the structure more adaptable during use.

[0014] 2. Insert and pull the shaft along the middle, high, or low opening to allow the pin to be filled with lubricating fluid in the barrel cavity for lubrication. This completes the lubrication and maintenance of the pin. The whole process is quick and convenient, facilitating efficient lubrication and maintenance of the pin. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a lubrication structure for pin maintenance:

[0023] like Figure 1-4 As shown, a lubrication structure for pin maintenance includes a storage tank 1 and a chamber 2 for storing lubricating fluid inside the storage tank 1. A glass plate 3 for viewing the chamber 2 is installed on the front wall of the storage tank 1. The storage tank 1 and the glass plate 3 are bonded together, and the chamber 2 and the mounting base 4 are engaged with each other. Through the viewing characteristics of the glass plate 3, the height of the lubricating fluid stored in the chamber 2 can be observed to understand the usage of the lubricating fluid.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a card seat 4 is installed near the top of the storage tank 1 near the top of the tank cavity 2. A cover seat 5 that matches the size of the storage tank 1 is placed on the upper end of the card seat 4. A through-hole 6 is opened through the cover seat 5 and the card seat 4. The card seat 4 and the cover seat 5 are fixedly connected. The card seat 4, the cover seat 5 and the storage tank 1 are all disc-shaped. The top of the through-hole 6 is truncated cone-shaped and the bottom is cylindrical. The end wall of the through-hole 6 is bonded to the sponge sleeve 7. The pin passes through the sponge sleeve 7 and passes through the through-hole. Excess lubricant on the end wall of the pin is scraped off and seeps down along the top of the through-hole 6. The through-hole 6 is wide at the top and narrow at the bottom, which facilitates the lubricant falling into the through-hole 6. It seeps down along the through-hole 6 and flows into the tank cavity 2. The sponge sleeve 7 is made of sponge material, which has deformability and absorbency. It can simply absorb some lubricant. The deformability allows the pin to pass through and the absorbency is used to absorb the lubricant and lubricate the end wall of the pin that passes through.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a sponge sleeve 7 is installed on the inner wall of the through 6. The sponge sleeve 7 has a through opening for the pin to pass through. The through opening includes a middle opening 8, a high opening 9, and a low opening 10. There are seven sponge sleeves 7. The four sponge sleeves 7 near the left and right sides of the cover 5 have the middle opening 8. The two sponge sleeves 7 near the front and rear sides of the cover 5 have the high opening 9. The sponge sleeve 7 at the center end wall of the cover 5 has the low opening 10. There are a total of six middle openings 8 and high openings 9. The middle openings 8 and high openings 9 are arranged in a ring around the center of the cover 5. The diameter of the high opening 9, middle opening 8, and low opening 10 decreases in sequence to allow pins of different sizes to pass through, making the entire structure more adaptable.

[0026] Working principle:

[0027] The barrel cavity 2 is used to add lubricating fluid. The transparent properties of the glass plate 3 are used to observe and understand the level of lubricating fluid in the barrel cavity 2. The top of the barrel cavity 2 is connected to the card seat 4, which allows the storage barrel 1 and the cover seat 5 to be assembled together. The opening 6 in the cover seat 5 is used to connect the sponge sleeve 7, and during the process of taking the pin out of the storage pin, the excess lubricating fluid on the end wall is scraped off and flows back into the barrel cavity 2 along the opening 6.

[0028] There are seven sponge sleeves 7 in total. Each sponge sleeve 7 has a passage opening. The passage openings are divided into medium openings 8, high openings 9, and low openings 10 of different sizes. Among them, four medium openings 8, two high openings 9, and one low opening 10 are used to insert and pass through pins of different sizes, adapting to different sizes of pins and making the structure more adaptable when used.

[0029] During lubrication, insert the pin along the middle opening 8, high opening 9, or low opening 10 to allow the pin to be immersed in the lubricant in the barrel cavity 2 for lubrication. Then pull the pin up, and the excess lubricant at the pin end wall is scraped off and absorbed by the sponge sleeve 7, completing the operation of lubricating and maintaining the pin. The whole process is quick and convenient, facilitating efficient lubrication and maintenance of the pin.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
