Description

Technical Field

[0001] The utility model relates to a shock absorber, in particular to a shock absorber which is easy to maintain and belongs to the technical field of shock absorbers. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of the spring after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the smoothness of the car's ride. The elastic elements in the automobile suspension system vibrate due to the impact. To improve the smoothness of the car's ride, shock absorbers are installed in parallel with the elastic elements in the suspension. To attenuate the vibration, the shock absorbers used in the automobile suspension system are mostly hydraulic shock absorbers. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] Shock absorbers are generally divided into single-stem hydraulic shock absorbers and strut-type shock absorbers. The most commonly used one is the strut-type shock absorber. The strut-type shock absorber is mainly composed of a top strut mounting seat, a coil spring, a dust cover, a spring separator and a shock-absorbing hydraulic rod. In the Chinese patent application announcement number CN209430671U, a car shock absorber that is easy to maintain is disclosed. The device balances the internal and external air pressures of the inner sleeve and the outer sleeve through heat dissipation vents to improve the resistance caused by the air pressure. However, the device is difficult to quickly replace the dust cover on the shock-absorbing hydraulic rod. The strut-type shock absorber is an important part of the vehicle during driving. One of the components, the dust cover on the shock-absorbing hydraulic rod will rupture due to aging and repeated extrusion during long-term driving of the vehicle. The rupture of the dust cover makes it difficult to protect the shock-absorbing hydraulic rod, which will cause damage to the shock-absorbing hydraulic rod oil seal. During the maintenance process of replacing the dust cover of the strut-type shock absorber, since the dust cover is generally fixed to the shock-absorbing hydraulic rod by multiple bolts, multiple bolts need to be removed during disassembly and installation, making it difficult for the staff to quickly remove and replace it during the maintenance process. In addition, when there are no special disassembly tools around the maintenance personnel, it is difficult to replace the dust cover and the damaged shock-absorbing spring in time.

[0006] Technical Solution

[0007] The utility model is implemented through the following technical scheme: a shock absorber that is easy to maintain, comprising a shock-absorbing telescopic oil rod, the outer surface of the fixed end of the shock-absorbing telescopic oil rod is fixedly connected with a fixing ring, the outer surface of the fixing ring is fixedly connected with a baffle plate 1, the outer surface of the telescopic end of the shock-absorbing telescopic oil rod is sleeved with a dustproof telescopic cover, the outside of the telescopic end of the shock-absorbing telescopic oil rod is provided with a quick-release mechanism, the quick-release mechanism comprises a sleeve, a top support seat and three movable threaded blocks, the sleeve is fixedly connected to one end of the dustproof telescopic cover, the outer surface of the telescopic end of the shock-absorbing telescopic oil rod is sleeved with a baffle plate 2, the outer surface of the baffle plate 2 is fixedly connected with three fixed threaded blocks, and the three fixed threaded blocks and the three movable threaded blocks are all threadedly connected to the top support seat.

[0008] Four linkage mechanisms are arranged outside the fixed end of the shock-absorbing telescopic oil rod, and the linkage mechanism includes a plug plate and a lock tongue. The plug plate is fixedly connected to the outer surface of the dust-proof telescopic cover, the plug plate passes through the outer surface of the fixing ring and is slidably connected to the fixing ring, and the outer surface of the plug plate is provided with a card slot adapted to the lock tongue.

[0009] Preferably, a latch is fixedly connected to the outer surface of the movable threaded block, and the telescopic ends of the sleeve and the shock-absorbing telescopic oil rod are provided with limiting holes corresponding to the latch. When assembling the device, the dust-proof telescopic cover is sleeved on the outer surface of the telescopic end of the shock-absorbing telescopic oil rod, the shock-absorbing spring is sleeved on the outer surface of the dust-proof telescopic cover, and the latch is inserted into the sleeve and the shock-absorbing telescopic oil rod, thereby completing the assembly and installation of the device.

[0010] Preferably, the outer surface of the movable thread block is fixedly connected to two sliders, and the outer surface of the fixed thread block is provided with two sliding grooves adapted to the sliders. The sliders are slidingly connected to the movable thread block through the sliding grooves of the movable thread block.

When the hinge seat moves close to the baffle, the hinge seat will drive the lock tongue away from the plug plate through the hinge rod, thereby causing the lock tongue to cancel the limiting effect on the plug plate.

[0014] Preferably, a long rod is fixedly connected to the outer surface of the articulated seat, and the long rod is slidably connected to the slide rail. The outer surface of the fixed end of the shock-absorbing telescopic oil rod is sleeved with a paddle, and the paddle is fixedly connected to the long rod. The outer surface of the long rod is sleeved with a telescopic spring, and the telescopic spring is fixedly connected between the articulated seat and the slide rail. Through the setting of the telescopic spring, the articulated seat is subjected to the spring pressure of the telescopic spring to keep the lock tongue in the card slot of the plug plate.

[0015] The utility model provides a shock absorber that is easy to maintain, and has the following beneficial effects:

[0016] The shock absorber which is easy to maintain is provided with baffle plate 2. The top support seat is separated from the three fixed threaded blocks by rotating the top support seat, so that the three movable threaded blocks can be directly pulled and removed. The baffle plate 2 will no longer be limited and can be separated. Therefore, the staff can directly disassemble the shock absorbing spring from the device and replace it with a new part. During the replacement process, the shock absorbing spring can be removed and installed without using other auxiliary tools, thereby increasing the convenience of the device during maintenance.

[0017] The shock absorber which is easy to maintain is provided with a dustproof telescopic cover and a linkage mechanism. When the dustproof telescopic cover is to be dismantled and replaced, the second baffle plate is first separated from the device, and then the paddle is pressed to move close to the first baffle plate, so that the paddle plate is moved by pressing the hinge seat through the long rod. The movement of the hinge seat drives the lock tongue to move away from the plug plate through the hinge rod, so that the plug plate is no longer restricted, and the staff can separate the dustproof telescopic cover from the device. The device can quickly remove the dustproof telescopic cover by only pressing the paddle plate, thereby increasing the convenience and speed of the device. BRIEF DESCRIPTION OF THE DRAWINGS
