Description

A snap-on pressing mechanism

technical field

The invention relates to the field of pipeline installation brackets, in particular to a snap-on pressing mechanism.

Background technique

Existing pipe mounting bracket products include: saddle-type compactor, rotary handle compactor, pipe tie, and pull-up tape. These fixing brackets have the following problems:

Defects of saddle-type compactors, tube ties, and drawstrings: complex and laborious compaction operations; poor flexibility

Defects of the rotary handle compactor: the operation efficiency of pressing and loosening is low, there is no elastic force, and it cannot adapt to the application of thermal expansion and contraction.

SUMMARY OF THE INVENTION

The invention provides a snap-type pressing mechanism, aiming at solving the problem of low pressing and loosening operation efficiency of the existing mounting bracket.

The present invention provides a snap-on pressing mechanism, which includes a clip seat, a pressing block, a hook, an elastic block and a guide rod. The elastic block includes a first elastic block and a second elastic block, and the pressing block passes through the first elastic block. The elastic block is connected to the card seat, and the guide rod penetrates through the pressure block and is fixedly connected to the card seat. Press the pressure block to move in a directional compression along the guide rod, or move along the guide rod under the action of the first elastic block. Directional pop-up movement, the hook is connected to the pressure block, and the card seat is provided with a self-locking slot matched with the hook. Pressing the pressure block makes the hook snap into the self-locking groove and lock the pressure block in the clip. On the seat, the bottom of the card seat is provided with a fixture groove for placing the object to be fixed, one end of the second elastic block is fixedly connected to the bottom of the pressure block, and the other end of the second elastic block is elastically attached to the object to be fixed after pressing the pressure block. connect. The pressure block realizes the directional movement on the card seat through the guide rod, which determines the moving direction of the pressure block when pressing and contacting and fixing. It helps the pressing block to pop up. When pressing, it cooperates with the hook and the self-locking groove, so that the pressing block is fixed on a certain height of the card holder and the object to be fixed is pressed.

As a further improvement of the present invention, the pressing block is provided with a guide hole, the guide rod passes through the guide hole and is fixed on the card seat, the top of the guide rod is provided with a rod cap, and the diameter of the guide hole is larger than that of the guide rod The diameter of the rod body is smaller than the diameter of the rod cap, and when the pressure block bounces up, the rod cap tops the top of the column pressure block and limits the height at which the pressure block bounces. The rod cap acts as a limit for the spring up of the pressure block, preventing the pressure block from bouncing too much and causing it to be separated from the card seat and fall apart.

As a further improvement of the present invention, the guide rod is a shaft screw, the first elastic block is a spring, the clip is provided with a threaded hole, and one end of the spring is attached to the bottom of the pressing block and aligned with the guide hole.
