Description

Technical Field

[0001] This patent relates to the technical field of shock absorber maintenance equipment, specifically to shock absorber oil port insertion equipment. Background Art

[0002] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. The shock absorber stores the shock absorber oil inside. However, after a period of use, the shock absorber is prone to oil leakage due to the aging of the oil seal. At this time, the oil seal needs to be replaced and the shock absorber oil needs to be refilled.

[0003] The existing shock absorber oil port insertion device, that is, the oil filling device, is not stable after being inserted into the shock absorber's oil filling port. When pushing the piston rod to fill oil into the shock absorber, if too much force is used, it is easy to disconnect from the shock absorber oil filling pipe, resulting in shock absorber oil leakage.

Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-3 This patent provides a technical solution: a shock absorber oil port insertion device, comprising a shock absorber 1 and an oil filling cylinder 2, the side wall of the shock absorber 1 is provided with an oil filling pipe 3, the side wall of the oil filling cylinder 2 is provided with an external thread, the side wall of the oil filling cylinder 2 is provided with an insertion cylinder 4 which is installed by thread rotation, and the insertion cylinder 4 can be inserted into the oil filling pipe 3;

[0022] The oil filling cylinder 2 and the insert cylinder 4 are connected by threads, so the two can be disassembled and separated, so as to facilitate the cleaning of the inner cavity of the oil filling cylinder 2, and also facilitate the addition of shock absorber oil into the oil filling cylinder 2;

[0023] A fixing ring 5 is installed on the outside of the oil filling cylinder 2, and convex plates 6 are installed on the left and right sides of the fixing ring 5. The side walls of the two convex plates 6 are provided with through holes 7, and bolts 8 are inserted and installed in the through holes 7. An arc plate 9 is installed at one end of the bolt 8 away from the convex plate 6, and the arc plate 9 can fit with the side wall of the shock absorber 1;

[0024] By rotating the nut 10, the distance between the arc plate 9 and the insertion tube 4 is shortened, so that the device is clamped outside the shock absorber 1, and the positions of the oil injection tube 2 and the insertion tube 4 are fixed to prevent the device from being offset during the subsequent oil injection, resulting in oil leakage in the reducer;

[0025] A nut 10 is screwedly mounted on the outer side of one end of the bolt 8 away from the arc-shaped plate 9 , and the nut 10 can fit with the side wall of the convex plate 6 .

[0026] Specifically, a sealing plate 11 is installed at one end of the oil filling cylinder 2 away from the insertion cylinder 4, a clearance hole 12 is opened in the middle of the sealing plate 11, a piston rod 13 is inserted into the clearance hole 12, and a piston block 14 is installed at one end of the piston rod 13 located inside the oil filling cylinder 2, and the piston block 14 is in contact with the inner wall of the oil filling cylinder 2;

[0027] When the piston rod 13 is pushed, the piston rod 13 drives the piston block 14 to move in the oil filling cylinder 2 , so that the reducer oil inside is injected into the reducer 1 through the insertion cylinder 4 .

[0028] Specifically, the insertion cylinder 4 includes a cylinder body 41, a groove 42 and a connecting cylinder 43. The inner side of the cylinder body 41 is provided with an internal thread, and the cylinder body 41 is installed on the outside of the oil filling cylinder 2 by threaded rotation. The side wall of the cylinder body 41 is provided with a groove 42, and the oil filling pipe 3 can be inserted into the groove 42. The connecting cylinder 43 is inserted and installed on the inner side of the groove 42. The inner cavity of the connecting cylinder 43 is connected with the inner cavity of the oil filling cylinder 2, and the connecting cylinder 43 can be inserted into the oil filling pipe 3.

[0029] Specifically, a block 15 is slidably installed in the inner cavity of the oil filling pipe 3, and the block 15 can block the oil filling pipe 3. A support rod 16 is installed on the side wall of the block 15, and support plates 17 are installed on the left and right sides of the support rod 16. One end of a spring 18 is installed on the side wall of the support plate 17, and the other end of the spring 18 is fitted and connected to the side wall of the oil filling pipe 3.

[0030] When filling oil, after the connecting tube 43 is inserted into the oil filling pipe 3, the connecting tube 43 will push the support rod 16 inward, so that the block 15 is deeply inserted into the reducer 1, thereby releasing the blockage of the oil filling pipe 3, and then push the piston rod 13 to inject the reducer oil in the oil filling tube 2 into the reducer 1;

[0031] When the connecting tube 43 is pulled out from the oil filling pipe 3 , under the action of the spring 18 , the support rod 16 can drive the blocking block 15 to return to its original position, thereby blocking the oil filling pipe 3 .

[0033] In this device, a plurality of slots 19 are provided on the piston rod 13, and the plurality of slots 19 are evenly spaced on the piston rod 13. When the snap ring 20 is snapped into the slot 19 near the sealing plate 11, the snap ring 20 will fit with the sealing plate 11, thereby preventing the piston rod 13 from moving inward, causing the reducer oil in the oil filling cylinder 2 to be squeezed out.

[0034] Specifically, the outer wall of the oil filling cylinder 2 is provided with scale lines;

[0035] The reducer oil can be easily measured by setting the scale line.

[0036] Working principle: first insert the insertion tube 4 into the oil filling tube 3, then rotate the nut 10 to shorten the distance between the arc plate 9 and the insertion tube 4, so that the device is clamped on the outside of the shock absorber 1, and the connecting tube 43 will push the support rod 16 inward to make the block 15 penetrate into the reducer 1, thereby releasing the blockage of the oil filling tube 3, and then push the piston rod 13, the piston rod 13 will drive the piston block 14 to move in the oil filling tube 2, so that the reducer oil inside is injected into the reducer 1 through the insertion tube 4.
