Description

Shock absorber pressing device

The invention relates to a shock absorber, and more particularly to a shock absorber pressing device.

Shock absorbers (or shock absorbers) are often used on vehicle bodies. For example, suspension shock absorbers can be used to absorb vibrations generated when vehicles pass over uneven roads, or steering shock absorbers are available. To suppress the vibration of the steering wheel of the vehicle.

However, when installing the shock absorber to the vehicle body, the user usually first locks the group connector on one side to the vehicle body, and then presses the shock absorber by hand or using any surrounding object to make the other The group of connectors on one side can correspond to the position of the screw lock, which is very labor-intensive, time-consuming, and there is a concern of damaging the shock absorber. In addition, when the shock absorber is removed, when the joint of one side of the group is released, the shock absorber will suddenly elongate and cause an unexpected collision, which has the disadvantages of urgent improvement.

Therefore, it is necessary to provide a novel and progressive shock absorber pressing device to solve the above problems.

The main purpose of the present invention is to provide a shock absorber pressing device, which can effectively press the shock absorber, and then when the shock absorber is installed, it can be adjusted to a preloaded state for locking, and the shock absorber is to be disassembled. When going down, the relative position of the two sets of joints can also be maintained stably to prevent unexpected shocks caused by the sudden and no pressure extension of the shock absorber.

To achieve the above object, the present invention provides a shock absorber pressing device, which is used for a shock absorber. The shock absorber includes a first group of joints, a shock absorbing unit and a second group of joints connected to each other. The shock absorber pressing device includes a telescopic mechanism and a clamping mechanism. The telescopic mechanism includes a first body, a second body, a linkage component and a driving unit. The first body and the second body are disposed on the linkage component, and the linkage component can selectively drive the first body and The second body expands and contracts in an actuation direction, and the driving unit is connected to the linkage component to form a linkage relationship. The drive unit is connected by a hand tool to drive the linkage component to drive the first body and the second body. Clipping against the shock absorber, the clipping mechanism includes a first pressing component and a second pressing component, the first pressing component is provided on the first body for abutting against the first group of joints, the A second pressing component is disposed on the second body for abutting against the second group of joints.
