Description

Technical Field

[0001] This utility model relates to the field of pin technology, and in particular to the assembly pin of a load-bearing linkage component. 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] When in use, the pin undergoes long-term hinge movement. The reciprocating motion generates friction, causing wear on the pin. The ordinary method of dripping lubricant requires aiming the lubricant at the pin's hole and connection, which is prone to mis-drip and is not convenient for maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an assembly pin for a load-bearing linkage component.

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

[0006] The assembly pin of the load-bearing linkage component includes a shaft seat, a shaft rod fixed at the center of the upper wall of the shaft seat, and a pin hole penetrating at the top end of the shaft rod. The shaft rod has an insertion port communicating with the pin hole, and the bottom wall of the shaft seat has a groove. The insertion port passes into the shaft seat and communicates with the groove.

[0007] Preferably, a plug rod is movably connected inside the socket, and a connecting disc that is threadedly connected to the groove is fixedly connected to the end of the plug rod.

[0008] Preferably, the connecting plate has an opening, and the connecting plate has connecting holes on its two side walls near the opening.

[0009] Preferably, the insert has a guide channel that communicates with the opening of the plate, and a sponge block is attached to the end wall of the insert away from the connecting plate.

[0010] Preferably, the insert has a flow guide hole near the sponge block.

[0011] Preferably, the shaft seat has an annular connecting port near the groove, and the bottom of the shaft seat has a sealing plate. The end wall of the sealing plate is fixed with an annular connector, and the connector is threadedly connected to the connecting port.

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

[0013] 1. Lubricant can be dripped into the groove, and the liquid will flow through the insertion port and seep out along the pin hole to lubricate and maintain the structure of the pin connection.

[0014] 2. Furthermore, a connecting disc can be threaded into the groove at the bearing seat. The insert rod fixed to the end wall of the connecting disc extends into the insertion port. Through the sponge block, it draws in the lubricant added in the guide channel and slowly releases it into the pin hole through the sponge block to lubricate and maintain the pin hinge connection structure.

[0015] 3. The connecting hole on the side of the pan is used to add lubricant. The lubricant is poured into the guide channel, passes through the guide hole, and wets the sponge block. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution for the assembly pin shaft with load-bearing linkage components:

[0024] like Figure 1-4As shown, the assembly pin of the load-bearing linkage component includes a shaft seat 1, a shaft rod 2 fixed at the center of the upper wall of the shaft seat 1, and a pin hole 3 penetrating at the top end of the shaft rod 2. The shaft rod 2 has an insertion port 4 communicating with the pin hole 3. The bottom wall of the shaft seat 1 has a groove 7, and the insertion port 4 passes into the shaft seat 1 and communicates with the groove 7.

[0025] Preferably, a plug rod 5 is movably connected inside the plug 4, and a connecting plate 6 that is threadedly connected to the end of the plug rod 5 is fixedly connected to the groove 7. The connecting plate 6 has an opening 8, and connecting holes 9 are opened on both sides of the connecting plate 6 near the opening 8.

[0026] Preferably, the insert rod 5 has a guide channel 10 that communicates with the plate opening 8, and a sponge block 12 is attached to the end wall of the insert rod 5 away from the connecting plate 6. A guide hole 11 is provided on the insert rod 5 near the sponge block 12.

[0027] The bearing seat 1 has an annular connecting port 13 near the groove 7. The bottom of the bearing seat 1 has a sealing plate 14. The end wall of the sealing plate 14 is fixed with an annular connector, which is threadedly connected to the connecting port 13.

[0028] Working principle:

[0029] Lubricant can be dripped into the groove 7, and after being guided through the insertion port 4, it seeps out along the pin hole 3 to lubricate and maintain the structure of the pin connection.

[0030] Furthermore, in the groove 7 at the bearing seat 1, the connecting disc 6 can be threadedly connected. The insert 5 fixed to the end wall of the connecting disc 6 extends into the insertion port 4. Through the sponge block 12, it draws the lubricant added in the guide channel 10 and slowly releases it into the pin hole 3 through the sponge block 12 to lubricate and maintain the pin hinge connection structure.

[0031] The connecting hole 9 on the side of the disc 8 is used to add lubricant. The lubricant is poured into the guide channel 10, passes through the guide hole 11, and wets the sponge block 12.

[0032] At the same time, the connecting plate 6 is screwed into the groove 7, which facilitates the sealing of the connecting hole 9 on the side wall of the connecting plate 6, and facilitates the sealing of the connecting hole 9.

[0033] At the connection port 13, a threaded sealing plate 14 is connected to press against the outer wall of the connecting plate 6, further increasing the sealing performance of the connection hole 9 at the connecting plate 6.

[0034] 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.
