[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a vehicle shock absorber stretching device, comprising a stretching platform 1, a fixed seat 2 is fixedly connected to the top of the stretching platform 1, the fixed seat 2 cannot move, and the fixed seat 2 has the same components as those on the moving seat 3, which can fix one end of the shock absorber on the fixed seat 2, and the top of the stretching platform 1 is slidably connected to the moving seat 3, and the inner wall of the moving seat 3 is penetrated and slidably connected to the moving plate 4, and the moving seat 3 is provided with an opening penetrated by the moving plate 4, so that the moving plate 4 can slide horizontally along the inner wall of the moving seat 3, and the inner wall of the moving plate 4 is slidably connected to a clamping plate 5, and the contact surface between the clamping plate 5 and the shock absorber is made of rubber material to avoid affecting the end of the shock absorber, and an inclined groove is provided on the moving plate 4, so that the moving plate 4 can move so that the inclined groove squeezes the clamping plate 5 to move it, and a limiting groove 6 is provided on the top of the moving plate 4, and the top of the moving seat 3 is elastically connected to the limiting block 8 through a reset spring 7, and the limiting block 8 is inclined. When squeezed, the limiting block 8 will move vertically along the inner wall of the moving seat 3, referring to Figure 4 A driving mechanism is provided at the bottom end of the stretching table 1.

[0031] Reference Figure 1 , Figure 2 and Figure 4The bottom end of the movable seat 3 is fixedly connected with a connecting plate 10, and a slot is provided on the stretching platform 1, so that the connecting plate 10 can slide along the inner wall of the slot of the stretching platform 1, and the side wall of the connecting plate 10 is fixedly connected with an L plate 11, and the top of the L plate 11 is fixedly connected with a pointer 12. By observing the position of the pointer 12 on the scale 13, it is convenient to subsequently detect the deformation degree of the shock absorber under different tensile forces, and evaluate its rebound speed and recovery ability. The top of the stretching platform 1 is fixedly connected with a scale 13, and the connecting plate 10 passes through and is slidably connected to the top of the stretching platform 1.

[0032] Reference Figure 1-Figure 3 The top of the moving seat 3 is fixedly connected to one end of the return spring 7. When the limit block 8 moves upward, the return spring 7 will be stretched. When resetting, the elastic force of the return spring 7 is used to reset the limit block 8. The other end of the return spring 7 is fixedly connected to the inner side wall of the limit block 8. The limit block 8 passes through and is slidably connected to the inner wall of the moving seat 3. The lower end of the moving seat 3 is plugged into the inner wall of the limit groove 6. The splint 5 passes through and is slidably connected to the inner wall of the moving seat 3. The moving seat 3 is provided with a slot for the splint 5 to slide. The driving mechanism includes an electric telescopic rod 9. The electric telescopic rod 9 is a device that controls the telescopic movement by a motor or an electric device. No more details are given here. The electric telescopic rod 9 is arranged on the bottom side wall of the stretching platform 1. The left end of the electric telescopic rod 9 is fixedly connected to the connecting plate 10. The connecting plate 10 passes through and is slidably connected to the inner wall of the stretching platform 1.

[0033] Working principle: First, when the shock absorber needs to be tensile tested, just place the two ends of the shock absorber in the middle of the fixed seat 2 and the movable seat 3 respectively, and then move the movable plate 4 to the left to let the inclined groove on the movable plate 4 squeeze the clamping plate 5, so that the two sets of clamping plates 5 are close to the middle and fix one end of the shock absorber. When the movable plate 4 moves, the inner wall of the limit groove 6 will squeeze the inclined surface of the limit block 8, so that the limit block 8 moves upward and stretches the reset spring 7. When the limit block 8 coincides with the notch of the next limit groove 6, the reverse elastic force of the reset spring 7 is used to reset the limit block 8, so that the limit block 8 and the notch of the limit groove 6 are plugged into the position of the entire movable plate 4 in one direction, which can quickly fix the two ends of the shock absorber.

[0034] During stretching, the electric telescopic rod 9 is started to move the left end of the electric telescopic rod 9 with the connecting plate 10, the moving seat 3, the L plate 11 and the pointer 12 to the right, and the pointer 12 is moved along the upper end of the scale 13. The stretching length of the shock absorber can be judged by observing the position of the pointer 12 on the scale 13, so as to subsequently observe the rebound speed and recovery ability of the shock absorber.

[0035] When the stretched shock absorber needs to be taken out, it is only necessary to move the limit block 8 upwards and stretch the return spring 7 to separate the limit block 8 and the notch of the limit groove 6, then move the movable plate 4 to the left, let the inclined surface on the movable plate 4 squeeze the clamping plate 5 to make the clamping plate 5 move away from one end of the shock absorber, and finally release the limit block 8 and use the reverse elastic force of the return spring 7 to reset the limit block 8.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
