Technical field

The invention belongs to service technique fields, and in particular to a kind of dismounting side that limit switch bracket fixed screw is anti-loose Method.

Background technique

Limit switch is mounted on fixed bracket, needs first to screw out fixed screw completely when dismounting limit switch, herein Fixed screw is easy to fall off in the process.For this problem, a kind of anti-loose assembly and disassembly methods of limit switch bracket fixed screw are invented. During dismounting limit switch, fixed screw and limit switch keep connection, and integral disassembly, assembly avoids fixed screw and falls, Form the risk of foreign matter.

Summary of the invention

The purpose of the present invention is to provide a kind of assembly and disassembly methods that limit switch bracket fixed screw is anti-loose, reduce and fix The risk that screw is fallen.

In order to achieve the above objectives, the technical solution used in the present invention are as follows:

A kind of assembly and disassembly methods that limit switch bracket fixed screw is anti-loose, fixed screw is by screw head and screw rod group At, respectively measure screw head outer diameter and screw rod outer diameter；In the horizontal plane that limit switch bracket is connected with limit switch Upper cutting mounting hole and mounting groove；According to the installation site of limit switch, mounting groove is cut in the adjacent position of mounting hole；Limit When switch installation, first 3-4 in fixed screw precession limit switch is enclosed, limit switch is equipped with to the horizontal plane court of fixed screw Mounting hole is vertically put into limit switch bracket, and by fixed screw, after limit switch and limit switch bracket are adjacent to, will be limited Switch is slided along mounting groove, selects suitable position, be tightened screw；When limit switch is dismantled, first fixed screw is revolved Loose 3-4 circle, slides into mounting hole along mounting groove for fixed screw, limit switch and fixed screw is taken out from mounting hole.

The quantity of the mounting hole and mounting groove is identical as fixed screw quantity.

The aperture of the mounting hole is slightly larger than the outer diameter of screw head, it is ensured that screw head can pass through mounting hole.

The width of the mounting groove is slightly larger than the outer diameter of screw rod, it is ensured that screw rod can slide in mounting groove, and screw Head will not deviate from from mounting groove.

The length of the mounting groove is determined according to limit switch installation site.

It is obtained by the present invention to have the beneficial effect that

During dismounting limit switch, fixed screw is connected on limit switch, does not have the wind that fixed screw is inadvertently fallen off Danger.

Specific embodiment

The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.

As shown in Fig. 1-3, the anti-loose assembly and disassembly methods of limit switch bracket fixed screw of the present invention are as follows:

Fixed screw 2 is made of screw head 6 and 7 two parts of screw rod, measures the outer diameter and screw rod 7 of screw head 6 respectively Outer diameter.

Mounting hole 4 and mounting groove 5 are cut on the horizontal plane that limit switch bracket 3 is connected with limit switch 1.Mounting hole 4 and mounting groove 5 quantity it is identical as 2 quantity of fixed screw.

The aperture of mounting hole 4 is slightly larger than the outer diameter of screw head 6, it is ensured that the screw head 6 of fixed screw 2 can pass through peace Fill hole 4.According to 1 installation site of limit switch, mounting groove 5 is cut in the adjacent position of mounting hole 4,5 width of mounting groove omits Greater than the outer diameter of screw rod 7.Ensure that screw rod 7 can slide in mounting groove 5, and screw head 6 will not be deviate from from mounting groove 5. The length of mounting groove 5 is determined according to 1 installation site of limit switch.

When limit switch 1 is installed, first 3-4 in 2 precession limit switch 1 of fixed screw is enclosed, limit switch 1 is equipped with solid The horizontal plane of screw 2 is determined towards limit switch bracket 3.And fixed screw 2 is vertically put into mounting hole 4, limit switch 1 and limit After switch bracket 3 is adjacent to, limit switch 1 is slided along mounting groove 5, selects suitable position, be tightened screw 2.

When limit switch 1 is dismantled, fixed screw 2 is first unscrewed into 3-4 circle, fixed screw 2 is slid into peace along mounting groove 5 Hole 4 is filled, limit switch 1 is taken out from mounting hole 4 with fixed screw 2.
