The utility model can level the entire wooden keel at any time as needed by setting the bolt column and the nut, which is very convenient and quick.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned adjustable bolts for fixing wooden keels in stage wooden floors have problems: the existing leveling keels have great limitations in use. When the gap between the outer side of the leveling bolt and the wall is large and the length of the leveling bolt inserted into the wall is small, the overall structure is unstable, the leveling screw is weak at the fixing part of the wall, the strength is small, and it is easy to shake. The bolt has a large contact surface and an extended sleeve, which effectively solves the stability problem when the contact point is weak and the distance between the leveling screw and the wall is large. The new bolt has a large contact surface and an extended sleeve, which effectively solves the problem of weak contact surface and thin wall. Therefore, a leveling keel combination bolt is proposed.

The bolt has a large contact surface and an extended sleeve, which effectively solves the stability problem when the contact point is weak and the distance between the leveling screw and the wall is large. The new bolt has a large contact surface and an extended sleeve, which effectively solves the problem of weak contact surface and thin wall.

[0006] The technical solution of the utility model is as follows: a leveling keel assembly bolt comprises: a bolt rod, a connecting block fixedly connected to one end of the bolt rod, a screw barrel threadedly connected to the outer side wall of the bolt rod, and a mounting plate sleeved on the outer side wall of the bolt rod, wherein the mounting plate is fixedly connected to one end of the screw barrel;

[0007] The mounting plate is provided with two screw holes, and the two screw holes are arranged diagonally opposite to each other.

[0008] Preferably, fixing wires are provided through the inside of the two screw holes, and the fixing wires are used to fix the mounting plate to the wall.

[0009] Preferably, two circular frames are fixedly mounted on one side of the mounting plate facing the screw barrel, the two circular frames are located at the positions of the two screw holes, and the outer side walls of the two circular frames are both sleeved with rubber clamping rings.

[0010] Preferably, a sealing shell is provided on one side of the two circular frames, and a clamping groove which is engaged with the rubber clamping ring is provided inside the sealing shell.

[0011] Preferably, a rectangular groove is formed on a side of the mounting plate away from the screw barrel, and a rectangular anti-slip pad is embedded in the rectangular groove.

[0012] The working principle and beneficial effects of the utility model are:

[0013] By threading the bolt barrel on the outer wall of the bolt rod and sleeve-mounting the mounting plate, the contact area between the bolt rod and the wall is increased, effectively maintaining the overall stability, thereby solving the stability problem when the contact point is weak and the distance between the bolt rod and the wall is large, and effectively preventing the overall structural instability. The leveling screw is weak at the fixed position on the wall, has low strength, and is easy to shake, thereby improving the use efficiency of the leveling keel combination bolts.
