Description

Technical Field

[0001] This utility model relates to the field of guide technology, specifically to a guide structure that is easy to assemble. Background Technology

[0002] The guide is an important component in automotive shock absorbers. It connects the piston rod and the inner and outer cylinders and is centrally positioned. The inside of the guide is usually fitted with a bushing in a nested manner, and the bushing is coated with PTFE to reduce friction.

[0003] According to a search, Chinese patent document, publication number CN214946001U, discloses a guide assembly for automotive shock absorbers. This assembly features several circumferentially evenly distributed positioning ribs on the outer peripheral wall of the bushing, and positioning grooves on the inner sidewall of the first annular step for engaging with these ribs. After the bushing is inserted into the guide body, each positioning rib engages with the positioning groove. This effectively prevents the bushing from rotating relative to the guide body during the long-term reciprocating motion of the piston rod relative to the bushing, thus preventing wear between the bushing and the guide body and preventing the bushing from detaching from the guide body, thereby effectively preventing damage to the automotive shock absorber. However, this guide assembly only increases the friction of the bushing by providing anti-slip grooves; it cannot limit the upper and lower ends of the bushing. During use, the upper and lower positions of the bushing may shift, and the stability of the assembly is not improved. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figure 1-5As shown, the present invention provides an easy-to-assemble guide structure, including a guide body 1 and a bushing 2. An annular step 3 is fixedly installed inside the lower end of the guide body 1. A guide groove 4 is opened on the inner side of the annular step 3. A guide block 5 is fixedly installed on the outer side of the bushing 2. A limit ring 6 is fixedly installed on the outer side of the upper end of the bushing 2. A positioning ring 7 is provided at the upper end of the annular step 3. A slot 8 is opened at the lower end of the positioning ring 7. An extension 9 is fixedly installed on the outer side of the positioning ring 7. A fixing seat 10 is fixedly installed inside the guide body 1. A cavity 11 is opened inside the fixing seat 10. A positioning pin 12 is movably installed inside the fixing seat 10. A protrusion 13 is fixedly installed on the outer side of the positioning pin 12. A spring 14 is provided inside the cavity 11.

[0032] Specifically, bushing 2 is fitted onto the inner side of the annular step 3, and the centers of the guide body 1, bushing 2, and annular step 3 are located on the same vertical line. The advantage is that bushing 2 fits inside the guide body 1 from top to bottom.

[0033] Specifically, the guide block 5 fits against the inner side of the guide groove 4, and four guide grooves 4 and four guide blocks 5 are arranged in a ring. The limiting ring 6 fits against the upper end of the annular step 3, and the center of the limiting ring 6 and the center of the bushing 2 are on the same vertical line. The advantage is that the guide block 5 is aligned with the guide groove 4, which guides the bushing 2 and prevents it from rotating, and the limiting ring 6 prevents the bushing 2 from moving downwards out of the inner side of the annular step 3.

[0034] Example 2:

[0035] like Figure 1-5 As shown, this is an improvement on the previous embodiment. Specifically, the limiting ring 6 fits against the inner side of the slot 8, and the center of the positioning ring 7 is on the same vertical line as the center of the limiting ring 6. The advantage is that after the bushing 2 is installed, the positioning ring 7 is placed into the interior of the guide body 1 from top to bottom, and is fitted onto the upper end of the limiting ring 6 through the slot 8.

[0036] Specifically, the extension 9 fits into the lower end of the fixing base 10, and two extensions 9 and two fixing bases 10 are symmetrically arranged. The advantage is that after the positioning ring 7 is inserted, it can be rotated at a certain angle to move the extension 9 to the bottom of the fixing base 10.

[0037] Specifically, the protrusion 13 is located inside the cavity 11, and the spring 14 is sleeved on the outside of the positioning pin 12, with the upper end of the spring 14 fitting against the protrusion 13. The advantage is that when the positioning pin 12 is moved upwards, the protrusion 13 pushes the spring 14 upwards, compressing and deforming it. After the positioning pin 12 is released, the spring 14 returns to its original position, and the protrusion 13 applies a downward elastic force to the positioning pin 12, thus achieving a resetting effect.

[0038] Specifically, the surface of the extension 9 has a through hole, and the lower end of the positioning pin 12 passes through the extension 9. The advantage is that when the positioning pin 12 passes through the interior of the extension 9, it plays a positioning role for the positioning ring 7.

[0039] In use, the bushing 2 is fitted inside the guide body 1 from top to bottom, and the guide block 5 is aligned with the guide groove 4. The guide block 5, in conjunction with the guide groove 4, guides the bushing 2 and prevents it from rotating during use. The fitting is completed when the top limiting ring 6 comes into contact with the upper end of the annular step 3. The limiting ring 6 prevents the bushing 2 from moving downward from the inside of the annular step 3. Then, the positioning ring 7 is placed inside the guide body 1 from top to bottom and fitted onto the upper end of the limiting ring 6 through the slot 8. Then, the positioning pin 12 is moved upward, and the protrusion 13 pushes the spring 14 upward, compressing and deforming it. The limiting ring 6 is then rotated to a certain angle, causing the extension 9 to move to the bottom of the fixed seat 10. Finally, the positioning pin 12 is released, and the spring 14 returns to its original position. The protrusion 13 applies a downward elastic force to the positioning pin 12, which serves as a reset function. The positioning pin 12 passes through the interior of the extension 9 and positions the positioning ring 7, thus completing the assembly of the bushing 2.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
