These traditional devices have their own advantages and disadvantages, and will inevitably become loose after long-term use, resulting in the problem that the panels cannot be firmly fixed.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a locking and fixing device for a plate, comprising:

[0008] A base, wherein a column is installed on the right side of the base;

[0009] A compression spring is arranged on the surface of the column, and the compression spring is sleeved on the outer circumference of the column;

[0010] The rotating block is arranged on the right side of the surface of the column. The front and back sides of the rotating block are both equipped with shaft pins, and the shaft pins are both connected to the surface of the column.

[0011] Preferably, a washer is sleeved on the right side of the surface of the column, and an adjustment block is provided on the left side of the surface of the column. The washer can help the compression spring disperse pressure and reduce stress concentration on the surface of the plate by increasing the contact area between the compression spring and the surface of the plate. In an environment of vibration or dynamic load, the washer can provide additional friction to help keep the column tight and prevent the column from loosening. It can also compensate for slight unevenness on the surface of the plate, ensuring that the compression spring can transmit force evenly and improving the sealing and reliability of the connection. The washer can reduce direct friction and wear between the compression spring and the surface of the plate, thereby protecting the compression spring from damage.

[0012] Preferably, a threaded groove is provided on the left side of the surface of the column, and a threaded groove is also provided on the inner wall of the adjustment block. The adjustment block is screwed to the surface of the column, and the rotating adjustment block can move along the threaded groove on the surface of the column, so that the compression spring can be squeezed again, so that the compression spring can squeeze the plate with a greater squeezing force, thereby improving the locking effect of the plate.

[0013] Preferably, the surface of the adjusting block is evenly provided with toggle rods, and the toggle rods are all installed on the surface of the adjusting block, so that the adjusting block can be conveniently rotated by the toggle rods.

[0014] Preferably, a mounting groove is provided on the right side of the surface of the column, and the rotating block is installed in the inner cavity of the mounting groove, so that the rotating block can rotate in the middle of the column, thereby being able to stably cooperate with the compression spring to fasten the plate.

[0015] Preferably, installation chambers are provided on the inner walls on both sides of the column, and the installation chambers are communicated with the inner cavity of the installation groove. The axle pins are installed inside the installation chambers. Installing the axle pins in the installation chambers can reduce the size of the inner cavity of the installation groove, thereby avoiding excessive size of the grooves on the surface of the column and ensuring the firmness of the column.

[0016] Beneficial Effects

[0017] Compared with the prior art, the present invention provides a locking and fixing device for a plate, which has the following beneficial effects:

[0018] The plate locking and fixing device is used. By aligning the tip of the rotating block with the mounting hole on the plate, the base can be pushed to drive the column and the compression spring to move. The column will drive the rotating block to penetrate the plate, and the front end of the compression spring will be compressed after contacting the plate. The base is continued to be pushed until the rotating block completely passes through all the plates. At the same time, the rotating block is moved to make it perpendicular to the plate. At this time, the compression spring and the rotating block can cooperate to automatically clamp the plate, which is convenient for installation and disassembly and can be reused. After long-term use, the compression spring can also squeeze the plate, thereby effectively preventing loosening and displacement between the plates. BRIEF DESCRIPTION OF THE DRAWINGS
