Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pneumatic shock absorber, especially a novel oil seal deflation needle. BACKGROUND

[0002] The pneumatic shock absorber uses the deflation needle, the existing oil seal deflation needle needle head is not round in design, is not fitted to the connecting rod when inserting into the shock absorber oil seal deflation, and the oil seal is easily scratched. SUMMARY

[0003] In order to solve the above-mentioned technical problem of easily scratching the oil seal, the utility model provides a novel oil seal deflation needle.

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

[0005] A novel oil seal deflation needle, including the pole seat, the pole seat front part is equipped with the needle head, the pole seat and needle head bottom surface are on the same horizontal plane, the needle head is located in the pole seat lower part, the needle head top surface is inclined, and the rear part is higher than the front part, and the pole seat bottom smooth surface extends to the pole seat middle position.

[0006] The needle head front part outer wall is arc-shaped, and the needle head and pole seat outer wall are smooth walls.

[0007] The smooth surface tail end is circular truncated cone, and the tail end contact wall body is inclined.

[0008] The pole seat top part both sides are arc-shaped.

[0009] The technical scheme of the utility model has novel structure, clever and simple design, and is fitted to the connecting rod on the needle head inner side, so that the oil seal and connecting rod are not easily damaged when being inserted into the connecting rod and oil seal cooperation part. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 , 2 , 3, 4 are the structure schematic diagram of the utility model;

[0011] Figure 5 It is the structure schematic diagram before improvement. DETAILED DESCRIPTION

[0012] The utility model will be further described in connection with the drawings and examples.

[0013] Embodiment

[0014] As Figure 1 , 2 , 3, 4 are a novel oil seal deflation needle, including the pole seat 1, the pole seat 1 front part is equipped with the needle head 2, the pole seat 1 and needle head 2 bottom surface are on the same horizontal plane, the needle head 2 is located in the pole seat 1 lower part, the needle head 2 top surface is inclined, and the rear part is higher than the front part, and the pole seat 1 bottom smooth surface 3 extends to the pole seat 1 middle position.

[0015] The outer wall of the front part of the needle 2 is arc-shaped, and the outer wall of the needle 2 and the rod seat 1 is smooth.

[0016] The tail end of the smooth surface 3 is frustoconical, and the tail end contact wall is inclined.

[0017] The top of the rod seat 1 is arc-shaped on both sides.

[0018] In use, the needle is lengthened, which is more convenient to operate and saves labor when deflating. Figure 5 As shown, the needle is sharp and short, and the needle is designed to be attached to the connecting rod, which is not easy to damage the oil seal and the connecting rod. When the shock absorber is returned to work in large quantities, this product does not need to be careful when deflating to avoid damaging the oil seal, which is more convenient to operate and saves labor when deflating, greatly improving the work efficiency.

[0019] It should be understood that the above only describes the preferred embodiments of the present application, and is not intended to limit the technical solutions of the present application. For those skilled in the art, under the spirit and principles of the present application, the above description can be increased, replaced, transformed or improved, and all these increased, replaced, transformed or improved technical solutions should belong to the protection scope of the appended claims of the present application.
