Description

Technical Field

[0001] The utility model relates to the technical field of bushings, in particular to an anti-falling automobile bushing. Background Art

[0002] There is an important part in the car, the car suspension, which includes control arms, connecting rods, etc. These parts will produce relative movement during the vehicle's driving, thereby generating friction. Therefore, bushings are needed to protect them so that each part can be isolated and buffered during relative movement.

[0003] Application number CN201920570979.4 relates to the field of auto parts technology. The key technical features of this solution include an inner tube, an outer tube, and a rubber body positioned between the inner and outer tubes. Both ends of the outer tube are bent toward the inner tube to form a retaining ring. The two ends of the rubber body rest against the side walls of the retaining rings facing the rubber body. The retaining rings prevent the rubber body from escaping from between the inner and outer tubes, reducing the possibility of the rubber body escaping and keeping it stably positioned between the inner and outer tubes, providing a stable shock-absorbing effect.

[0004] This device reduces the possibility of movement between the rubber body and the inner tube by providing a limit strip and a polygonal inner tube. However, a certain amount of wear will occur between the inner sleeve and the outer sleeve during long-term use. Long-term wear can easily cause the outer sleeve and the inner sleeve to become loose. In addition, the outer sleeve of this device is directly mounted on the outside of the inner sleeve, which makes it inconvenient to replace and repair the inside of the sleeve, thereby increasing the cost of maintenance.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original anti-falling automobile bushing structure. Utility Model Content

[0009] Preferably, the anti-slip assembly further includes a second anti-slip cap and a card slot, the second anti-slip cap is provided on the right side of the upper outer sleeve and the lower outer sleeve, and a card slot is provided on the inner side of the second anti-slip cap, and a card block is engaged and connected to the inner side of the card slot.

[0010] Preferably, the anti-slip assembly further comprises a fastening bolt, the fastening bolt passes through the inner side of the second anti-slip cap, and the tail end of the fastening bolt is connected to the threaded hole inside the clamping block.

[0011] Preferably, the positioning assembly includes a slide groove, a sliding block and a telescopic spring. The slide groove is opened at equal angles on the inner side of the inner sleeve, and the sliding block is slidably connected to the inner side of the slide groove. The sliding blocks are arranged in two groups symmetrically about the midpoint of the slide groove, and a telescopic spring is connected between the two groups of sliding blocks.

[0012] Preferably, the positioning assembly further comprises an adjusting rod and a top plate, the adjusting rod is rotatably connected to the outside of the sliding block, and the tail end of the adjusting rod is rotatably connected to the top plate.

[0013] Preferably, the top plates correspond to the inner walls of the upper outer bushing and the lower outer bushing, and six groups of top plates are arranged at equal angles with respect to the midpoint of the inner bushing.

[0014] Compared with the prior art, the beneficial effect of the present invention is that the anti-falling automobile bushing is provided with:

[0015] 1. Anti-slipping structure. When the outer sleeve needs to be fixed to the outside of the inner sleeve, the upper outer sleeve and the lower outer sleeve are first assembled on the outside of the inner sleeve, and then the first anti-slipping cap and the second anti-slipping cap are respectively sleeved on the left and right sides of the upper outer sleeve and the lower outer sleeve. After the sleeves are installed, the connecting rod is rotated by the concentric axis so that the clamping block at the tail end of the connecting rod is engaged with the clamping groove on the inner side of the second anti-slipping cap. After the engagement is completed, the fastening bolt is rotated so that the fastening bolt passes through the inner side of the second anti-slipping cap and is connected with the threaded hole on the inner side of the clamping block, so that the first anti-slipping cap and the second anti-slipping cap are fixed to the left and right sides of the upper outer sleeve and the lower outer sleeve, completing the assembly of the inner and outer sleeves to prevent the inner and outer sleeves from being separated.

[0017] 2. Buffering structure. The inner sleeve of this structure is set to a hexagonal shape and fits with the inner walls of the upper outer sleeve and the lower outer sleeve, thereby increasing the contact area of ​​the inner and outer sleeves to prevent sliding, which causes angular deviation of the inner and outer sleeves. A sliding groove is provided on the inner side of the inner sleeve. When the upper outer sleeve and the lower outer sleeve are assembled, the inner walls of the upper outer sleeve and the lower outer sleeve will squeeze the top plate, thereby rotating the adjustment rod on the outside of the top plate, pushing the sliding blocks on both sides to slide outward along the inner side of the sliding groove, and at the same time stretching the telescopic spring. When the upper outer sleeve and the lower outer sleeve are assembled with the inner sleeve, the top plate will generate an outward thrust through the elastic force of the telescopic spring, so that the top plate fits tightly against the inner wall of the outer sleeve, increasing the connection stability of the inner sleeve, and the telescopic spring can effectively absorb and disperse the impact force from the outside through its own elastic force, thereby playing a buffering role.
