Detailed Description

The present invention will be further described with reference to the accompanying drawings, wherein like structure is referred to by like names. In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Fig. 1 to 3 are schematic structural diagrams of a height-adjustable damping mechanism of the present invention, which include a damping mechanism body 0, a screw rod 1, an inner brace rod 3, an outer brace rod 4, a damper 7, a spring 9, a slider frame 10, and other parts installed in the damping mechanism body; the sliding of the sliding component is controlled by adjusting the rotation of a height adjusting handle 13 arranged on the screw rod 1, and the height is controlled by the sliding of the sliding component arranged at the bottom of the lower bottom plate.

The motion assembly comprises a screw rod 1, an inner support rod 3, an outer support rod 4, an outer support rod support 5, an upper base plate 6, a damper 7, a spring 9, a slider frame 10, a long bottom bushing 11, an adjusting nut 12 and a height adjusting handle 13. Wherein, the rotation of the height adjusting handle 13 is an external force, in particular, the relative height of the upper base plate 6 and the lower base plate 2 can be changed by rotating the height adjusting handle 13.

The lower base plate 2 is fixedly installed on the installation plane, so that the whole damping mechanism 0 can be fixed on a plane, and a relatively stable environment is brought for the operation of workers. One general flow of the whole damper mechanism body 0 assembled by the respective parts is: the two sliding block frames 10 are welded with the upper base plate 6, the two sliding block frames 10 are welded with the lower base plate 2, and some supports and fixing supports are also welded on the upper base plate and the lower base plate, so that two upper base plate assemblies and two lower base plate assemblies are formed; the rear ends of the two inner support rods 3 are connected with two supports on the lower bottom plate component by bolts, the middle parts of the two inner support rods are connected with the outer support rods 4 by bolts, the front ends of the two inner support rods are sleeved with two long bottom bushings 11 and then sleeved in two slide block frames 10 welded with the upper bottom plate, at the moment, lubricating oil is coated in the slide block frames 10, and the two long bottom bushings 11 slide in the slide block frames 10; the rear ends of the two outer support rods 4 are connected with the two outer support rod supports 5 on the upper bottom plate assembly through bolts, the middle parts of the two outer support rods are connected with the inner support rods 3 through bolts, the front ends of the two outer support rods are sleeved with two long bottom bushings 11 and then sleeved in two sliding block frames 10 welded with the lower bottom plate, lubricating oil is coated in the sliding block frames 10 at the moment, and the two long bottom bushings 11 slide in the sliding block frames 10; the middle parts of the upper bottom plate 2 and the lower bottom plate 6 are also connected with a damper 7; the whole damping mechanism is assembled by the components. Of course, the height adjustable handle assembly with applied force is an important component of the height adjustable shock absorbing mechanism.
