Description

Technical Field

[0001] This utility model relates to the field of shock absorber disassembly and assembly technology, specifically a quick-release connection device for a motorcycle rear shock absorber. Background Technology

[0002] In the motorcycle's structural system, the shock absorber is a crucial component, as its performance directly affects riding comfort and safety. Shock absorbers are used to suppress the oscillations when the spring absorbs shock and rebounds, as well as the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations, thereby improving the ride smoothness of the vehicle.

[0003] Shock absorbers are easily damaged parts in the use of automobiles. When a shock absorber malfunctions, it needs to be removed manually from the motorcycle seat. However, the shock absorber removal device requires the cooperation and assistance of others, which is time-consuming and labor-intensive. The disassembly process is labor-intensive and inefficient, and cannot meet the needs of shock absorber removal. Utility Model Content

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 4 A quick-release connection device for a motorcycle rear shock absorber includes a shock absorber body 3 and a U-shaped body seat 2. The top and bottom of the shock absorber body 3 are respectively fixedly connected with mounting ears 1. The mounting ears 1 and the U-shaped body seat 2 are provided with a plug-in mechanism 5. The mounting ears 1 and the U-shaped body seat 2 are provided with a fixing mechanism 4. The fixing mechanism 4 is located outside the plug-in mechanism 5.

[0028] The insertion mechanism 5 includes two long rods 58, which are inserted into the mounting ears 1 respectively. Long holes 54 are opened on the left and right sides of the long rods 58 respectively. T-shaped grooves 51 are opened on the left and right sides of the inner wall of the U-shaped seat 2 of the vehicle body. T-shaped blocks 57 are slidably connected inside the T-shaped grooves 51. Connecting plates 52 are fixedly connected to the two T-shaped blocks 57 near the limit rod 59. Insertion rods 55 are fixedly connected to the top two ends of the connecting plates 52 respectively. Insertion holes 53 are opened inside the limit rod 59. Bolts 56 are threadedly connected inside the limit rod 59 and the insertion rods 55.

[0029] The long hole slot 54 is set with openings on both the front and rear sides. The long hole slot 54 is set on the left and right sides of the mounting ear 1. The left and right sides of the vehicle body U-shaped seat 2 are respectively provided with through hole slots. The surface of the long rod 58 is inserted through and inserted into the through hole slots respectively opened on the left and right sides of the vehicle body U-shaped seat 2. The top and bottom of the insertion slot 53 are set with openings. The surface of the insertion rod 55 is inserted into the insertion slot 53. The insertion rod 55 is respectively set on the front and rear sides of the long rod 58.

[0030] Furthermore, when the bolt 56 is threaded, it pushes the connecting plate 52 to drive the T-block 57 to slide in the T-slot 51 until the connecting plate 52 drives the insertion rod 55 to move out of the insertion slot 53. Then, the limiting rod 59 is pulled out of the long hole slot 54, and the long rod 58 can be pulled out of the mounting ear 1 again, which facilitates the disassembly of the mounting ear 1 and the shock absorber body 3, and facilitates the disassembly and replacement of the shock absorber.

[0031] Example 2

[0032] See Figure 1-5 Furthermore, based on Embodiment 1, the fixing mechanism 4 includes a slide groove 47, which is opened at the top and bottom of the long rod 58. Connecting rings 42 are fixedly connected to the left and right sides of the vehicle body U-shaped seat 2 respectively. Slide plates 43 are fixedly connected to the top and bottom of the inner wall of the connecting rings 42. A cover plate 44 is hinged to the top of the connecting rings 42. An arc-shaped insert plate 41 is fixedly connected to the side of the cover plate 44 near the connecting rings 42. An arc-shaped slot 46 is opened inside the side of the connecting rings 42 away from the vehicle body U-shaped seat 2. Screws 45 are inserted into the cover plate 44 and the long rod 58.

[0033] The connecting ring 42 is set on the surface of the long rod 58, the cover plate 44 is set on the side of the long rod 58 away from the U-shaped seat 2 of the vehicle body, there are eight slide plates 43 in pairs, and there are two slide grooves 47. The surface of the slide plate 43 and the inside of the slide groove 47 are slidably connected.

[0034] Furthermore, after the screw 45 is removed by threading, the cover plate 44 is rotated at the top of the connecting ring 42, so that the cover plate 44 drives the arc-shaped insert plate 41 to move out of the arc-shaped slot 46, which facilitates the removal of the restrictions on both sides of the long rod 58 in the later stage, and makes it easy to pull the long rod 58 without obstruction in the later stage.

[0035] In actual operation, when this device is used, when it is necessary to remove the shock absorber body 3 from the U-shaped seat 2 on the motorcycle body, after the screw 45 is threaded off, the cover plate 44 is turned at the top of the connecting ring 42, so that the cover plate 44 drives the arc-shaped insert plate 41 to move out of the arc-shaped slot 46, which makes it easier to remove the restrictions on both sides of the long rod 58 later, and makes it easier to pull the long rod 58 without obstruction later.

[0036] Tighten the bolt 56 again, push the connecting plate 52 to make the T-block 57 slide in the T-slot 51 until the connecting plate 52 moves the insertion rod 55 out of the insertion slot 53. Pull the limit rod 59 out of the long hole slot 54, and then pull the long rod 58 out of the mounting ear 1. This makes it easy to disassemble the mounting ear 1 and the shock absorber body 3, and to disassemble and replace the shock absorber.
