Description

Technical Field

[0001] The utility model relates to the technical field of rail transit shock absorbers, and more specifically, to a tooling structure for fixing a dust cover of a rail transit shock absorber. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. In order to reduce the exposure of vehicle shock absorbers to dust in the environment during use, a dust cover is usually installed on the outside of the shock absorber's oil storage cylinder.

[0003] The traditional tooling structure for fixing the dust cover of rail transit shock absorber has the following shortcomings: when fixing the dust cover, the traditional tooling structure for fixing the dust cover of rail transit shock absorber generally connects it to the outside of the oil storage cylinder through bolts. This connection method requires the shock absorber to be removed from the vehicle body before it can be replaced during subsequent maintenance. This may cause the bolts to slip for a long time, resulting in unstable fixation of the dust cover, which may easily cause it to detach from the outside of the oil storage cylinder. Therefore, it needs to be improved. Utility Model Content

[0031] A fixing mechanism, which is arranged outside the fastening ring 3 and the sealing ring 20;

[0032] Wherein, the fixing mechanism includes a fixing outer ring 6;

[0033] The outer sides of the fastening ring 3 and the sealing ring 20 are fixedly installed with a bottom ring 7, the fixed outer ring 6 is fixedly connected to the outer side of the bottom ring 7, the outer side of the bottom ring 7 is fixedly installed with a connecting block 8, the interior of the connecting block 8 is provided with a movable groove 9, the interior of the movable groove 9 is fixedly installed with a round rod 10, the outer side of the round rod 10 is movably sleeved with a movable block 11, and the outer side of the movable block 11 is fixedly installed with an inclined fixed block 13 located on the inner side of the connecting block 8.

[0034] When it is necessary to install a dust cover on the right end of the shock absorber cylinder 1, first fix the dust cover body 1 4 and the dust cover body 2 5, then insert the two ends into the fixing mechanism respectively, rotate the knob 16, so that the knob 16 drives the threaded ring 15 to rotate, and the threaded ring 15 rotates inside the screw groove 14 to drive the threaded ring 15 to move downward, and the threaded ring 15 drives the triangular clamping ring 17 to move downward and contact the inclined surface fixing block 13, driving the inclined surface fixing block 13 to shrink inward, and the inclined surface fixing block 13 drives the movable block 11 to shrink inward inside the movable groove 9, squeezes the reset spring 12, and causes the reset spring 12 to deform, thereby fixing the dust cover through the inclined surface fixing block 13.

[0035] By inserting the two ends of the dust cover into the bottom ring 7 respectively, and then rotating the knob 16, the threaded ring 15 is rotated downward inside the screw groove 14 to drive the triangular clamping ring 17 to contact the inclined surface fixing block 13, so that the inclined surface fixing block 13 contracts inward to clamp and fix the two ends of the dust cover. Compared with the traditional tooling structure for fixing the dust cover of the rail transit shock absorber, this tooling structure for fixing the dust cover of the rail transit shock absorber rotates the knob 16 to make the inclined surface fixing block 13 move inward to clamp and fix the dust cover, which is convenient for subsequent maintenance and replacement by staff.

[0036] Wherein, the dustproof mechanism includes a dustproof cover body 4;

[0037] The dust cover body 1 4 is movably sleeved on the upper right end of the shock absorber cylinder 1, and the dust cover body 2 5 is movably sleeved on the lower right end of the shock absorber cylinder 1. The dust cover body 1 4 corresponds to the dust cover body 2 5. L-shaped blocks 18 are fixedly installed below both ends of the dust cover body 1 4. A slot 19 is opened between the inner sides of both ends of the dust cover body 2 5. The L-shaped block 18 corresponds to the slot 19.

[0038] When the dust cover needs to be installed, first align the dust cover body 1 4 and the dust cover body 2 5, insert the L-shaped card block 18 under the dust cover body 1 4 into the card slot 19 opened on the surface of the dust cover body 2 5, and then push the dust cover body 1 4 forward to make the L-shaped card block 18 move forward and be stuck in the card slot 19, and then insert the L-shaped card block 18 at the rear end of the dust cover body 1 4 into the card slot 19 at the rear end of the dust cover body 2 5, and push the rear end of the dust cover body 1 4 backward to fix it.

[0039] By aligning the L-shaped block 18 with the slot 19 and inserting it, and then pushing the dust cover body 1 4 so that the L-shaped block 18 is inserted into the inside of the slot 19 to fix it, compared with the traditional tooling structure for fixing the dust cover of the rail transit shock absorber, this tooling structure for fixing the dust cover of the rail transit shock absorber fixes the dust cover body 1 4 and the dust cover body 2 5 by pushing the L-shaped block 18 into the inside of the slot 19, which is convenient for the staff to install the dust cover.

[0040] A screw groove 14 is provided on the inner side of the fixed outer ring 6 , a threaded ring 15 is sleeved on the inner thread of the screw groove 14 , and a knob 16 is fixedly installed on the upper side of the threaded ring 15 .

[0041] The knob 16 is rotated to drive the threaded ring 15 to rotate, and the threaded ring 15 rotates and moves up and down inside the screw groove 14, thereby achieving the function of fixing the dust cover.

[0042] A return spring 12 is elastically installed between the inner side of the movable groove 9 and the inner side of the movable block 11 , and the return spring 12 is movably connected to the outer side of the round rod 10 .

[0043] The inclined fixed block 13 contracts inwardly, driving the movable block 11 to contract inwardly inside the movable groove 9, so that the movable block 11 squeezes the return spring 12, causing the return spring 12 to deform. When the triangular retaining ring 17 moves upward, the return spring 12 releases its elastic potential energy to push the inclined fixed block 13 back to its original position.

[0044] A triangular clamp ring 17 is fixedly installed below the threaded ring 15 , and the triangular clamp ring 17 corresponds to the inclined surface fixing block 13 .

[0045] The downward movement of the threaded ring 15 drives the triangular clamp ring 17 to move downward, and the downward movement of the triangular clamp ring 17 squeezes the inclined surface fixing block 13, so that the inclined surface fixing block 13 moves inward to fix the two ends of the dust cover.
