Description

Technical Field

[0001] The utility model relates to a horizontal bar shock absorber, in particular to a novel sealing air nozzle structure. Background Art

[0002] The single-bar shock absorber requires a sealed air nozzle, but traditional air nozzles on the market have defects such as difficulty in inflation, poor air tightness, and inability to withstand high pressure. Summary of the invention

[0003] In order to solve the technical problems of the difficulty in inflating and poor air tightness of the above-mentioned traditional air nozzles, the utility model provides a novel sealing air nozzle structure.

[0004] The technical solution of the utility model is as follows:

[0005] A novel sealing air nozzle structure comprises an air nozzle body, wherein the inner wall on the left side of the air nozzle body forms a chamber, a sealing rubber is arranged in the chamber, a baffle is arranged on the left side of the air nozzle body, the baffle fixes the sealing rubber by riveting, a mounting opening is arranged on the bottom cover, an inclined wall a is arranged on the inner wall of the mounting opening, an inclined wall b is arranged on the outer wall of the front part of the air nozzle body, the inclined wall a is in contact with the inclined wall b, and a mounting hole is arranged on the rear part of the air nozzle body, and a cross bolt is fixed on the mounting hole.

[0006] There is a depression at the contact point between the inner wall of the bottom and the air nozzle body, and an O-ring a is arranged at the depression.

[0007] A recessed groove is arranged on the right inner wall of the air nozzle body, and an O-ring is arranged in the recessed groove.

[0008] The sealing rubber is made of hydrogenated nitrile material.

[0009] The air nozzle body does not extend from the bottom cover.

[0010] The technical solution of the utility model has a novel structure, ingenious and simple design, and extremely high versatility. It is generally applicable to all horizontal bar shock absorbers and has low processing cost. The sealing rubber and the air nozzle adopt an interference fit and riveting design to make the structural sealing ring better. The bottom of the bottom cover adopts a sunken air nozzle design to make the outer tube more beautiful, which solves the problems of complicated assembly, mismatched inflation tools, and long-term slow deflation.

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] Example

[0017] like Figure 1 , 2 A new type of sealing air nozzle structure shown in 3 comprises an air nozzle body 1, wherein the left inner wall of the air nozzle body 1 forms a chamber 2, a sealing rubber 3 is arranged in the chamber 2, a baffle 4 is arranged on the left side of the air nozzle body 1, the baffle 4 fixes the sealing rubber 3 by riveting, a mounting opening is arranged on the bottom cover, an inclined wall a5 is arranged on the inner wall of the mounting opening, an inclined wall b is arranged on the front outer wall of the air nozzle body 1, the inclined wall a5 is in contact with the inclined wall b, and a mounting hole is arranged on the rear of the air nozzle body 1, and a cross bolt is fixed on the mounting hole.

[0018] There is a depression at the contact point between the inner wall of the bottom and the air nozzle body 1, and an O-ring a is provided at the depression.

[0019] A recessed groove is provided on the right inner wall of the air nozzle body 1, and an O-ring is provided in the recessed groove.

[0020] The sealing rubber is made of hydrogenated nitrile material.

[0021] The air nozzle body 1 does not extend from the bottom cover.

[0022] like Figure 4 As shown, when in use, first insert the sealing rubber 3 into the air nozzle body 1, and then use a special tool to rivet and fix the sealing rubber 3. The special tool completes the bending and pressing of the sealing rubber 3 through the inclined wall extrusion blocking body 4; after completion, insert the O-ring a sealed with the bottom cover, and screw the air nozzle body 1 into the bottom cover; then use the inflation needle to insert the sealing rubber 3 for inflation, and finally lock the cross bolt with the O-ring b. The sealing rubber 3 riveted into the air nozzle body 1 is made of hydrogenated nitrile material. The material has low hardness, the inflation needle is not easy to break, and it has a self-healing effect after the needle is pulled out and will not be deflated. It also has good high and low temperature resistance. A two-sealing design is adopted. After the air is inflated, a sealing ring is added to the outside of the sealing rubber 3 and sealed with a cross bolt.
