[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figure 1-Figure 7As shown, the utility model discloses an anti-slip automobile retaining ring, comprising a ring body 1 and a disassembly hole 11, one side of the ring body 1 is open, the number of the disassembly holes 11 is two and they are respectively located on the left and right sides of the ring body 1, the retaining ring is usually made of metal or plastic, and the shape is similar to a ring, and the interior has a certain elasticity, they are installed on the shaft, and the parts are prevented from sliding or loosening on the shaft by the force or friction on the shaft, the outer diameter of the retaining ring matches the inner diameter of the shaft hole to ensure that it is tightly embedded and maintains a stable position, and when the retaining ring needs to be installed or removed, the retaining ring pliers can be extended into the disassembly hole 11 of the retaining ring and then force is applied to it so that the retaining ring can be deformed and then separated from the shaft (this is the prior art and will not be elaborated here), and also includes each upper contact piece 2 that slides radially along the ring body 1, each upper contact piece 2 includes an upper mounting section 21 and an upper matching section 22, the The ring body 1 is respectively provided with an upper mounting groove 12 and an upper matching groove 13 corresponding to each upper mounting section 21 and an upper matching section 22. Each upper mounting section 21 is provided with an upper positioning column 211 protruding downward. The ring body 1 is provided with a plurality of upper positioning grooves 14 for the corresponding upper positioning columns 211 to be inserted in each upper matching groove 13. Each upper positioning column 211 is interference fit with the corresponding upper positioning groove 14. Since each upper contact piece 2 slides along the radial direction of the ring body 1, when the ring body 1 sleeved on the shaft is worn or the shaft is worn, causing the ring body 1 to become loose on the shaft, at this time, by sliding each upper contact piece 2 inward, at this time, with the sliding of the upper contact piece 2, the upper positioning column 211 on the upper mounting section 21 can cooperate with the upper positioning groove 14 at different positions, so that the upper matching section 22 can abut against the shaft to realize the inner wall of the ring body 1 contacting with the shaft again to realize the anti-slip of the retaining ring, thereby extending the service life of the retaining ring.
[0027] Preferably, each of the upper mating sections 22 includes a mass reduction groove 221 and a left contact section 222 and a right contact section 223 located on the left and right sides of the mass reduction groove 221, and each of the left contact section 222 and the right contact section 223 is provided with a plurality of contact grooves 2231. 1. Since the upper mating section 22 includes the mass reduction groove 221, the material loss in the manufacture of the upper mating section 22 can be effectively reduced, and it is convenient to apply force to it to make it slide and move the gap between the compensation ring body 1 and the shaft; 2. Since the left contact section 222 and the right contact section 223 are provided with a plurality of contact grooves 2231, the existence of each contact groove 2231 can effectively increase the roughness of the left contact section 222 and the right contact section 223, thereby increasing the friction between the left contact section 222 and the right contact section 223.
[0028] Among them, it also includes lower contact pieces 3 that slide radially along the ring body 1. The number of lower contact pieces 3 is the same as that of upper contact pieces 2 and they are respectively located below the corresponding upper contact pieces 2. The shape and size of each lower contact piece 3 are the same as those of the corresponding upper contact piece 2. Since each lower contact piece 3 is respectively located below the corresponding upper contact piece 2, each upper contact piece 2 and lower contact piece 3 can jointly play a role in moving and compensating for the gap between the shaft and the ring body 1. Since each upper contact piece 2 and lower contact piece 3 have the same shape and size, the setting of each lower contact piece 3 can increase the contact area between the ring body 1 and the shaft, so that after moving and compensating for the gap between the shaft and the ring body 1, each upper contact piece 2 and lower contact piece 3 can make the ring body 1 stably contact with the shaft.
[0029] Preferably, each of the lower contact members 3 includes a lower mounting section 31 and a lower mating section 32, and also includes a connecting plate 4 located between each upper mounting section 21 and the corresponding lower mounting section 31. The ring body 1 is provided with a sliding groove 15 corresponding to each connecting plate 4, and the ring body 1 is located on the outside of each sliding groove 15 and is open. Since each connecting plate 4 is respectively located between the corresponding upper mounting section 21 and the lower mounting section 31, each upper contact member 2 and the corresponding lower contact member 3 can be synchronously slid by applying force to the connecting plate 4, so that the two can be located at the same position at different heights to achieve compensation for the movement between the ring body 1 and the shaft.
[0030] Among them, each upper positioning column 211 includes an insertion section 2111 and a limiting ball 2112, and each upper positioning groove 14 includes an insertion section 141 and a limiting section 142. The diameter of each limiting ball 2112 is larger than the corresponding insertion section 2111. Since the diameter of each limiting ball 2112 is larger than the corresponding insertion section 2111, when the position of each upper mounting section 21 is determined, the limiting ball 2112 of each upper mounting section 21 needs to forcibly cross the insertion section 141 and then cooperate with the corresponding limiting section 142. Therefore, in the absence of external force, the upper positioning column 211 of the upper mounting section 21 can be stably located in the corresponding upper positioning groove 14 without colliding with other objects.
[0031] Among them, each of the upper contact pieces 2 also includes a matching piece 23 located in the mass reduction groove 221, and a lower matching column 231 is arranged at the bottom of each matching piece 23. The ring body 1 is located in the upper installation groove 12 and a plurality of insertion grooves 16 are arranged corresponding to each matching column. Since the matching piece 23 is provided with a lower matching column 231, in addition to placing the upper positioning column 211 of the upper installation section 21 into the positioning groove at the corresponding position, the lower matching column 231 of the matching piece 23 will be inserted into the corresponding insertion groove 16. The setting of the lower matching column 231 and the insertion groove 16 enables both sides of the upper contact piece 2 to be stably located in the ring body 1, so that the matching piece 23 will not move in the absence of external force and interfere with the use of the ring body 1.
[0032] Preferably, each of the mating pieces 23 is provided with a disassembly plate 24 protruding upward, and the outer side of the disassembly plate 24 is opened. Since the disassembly plate 24 is located above the mating piece 23, the mating piece 23 of the upper contact piece 2 can be flipped upward by applying force to the disassembly plate 24, thereby separating each lower mating column 231 from the corresponding insertion groove 16, thereby providing convenience for moving and adjusting the position of the upper contact piece 2.
[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
