Description

Technical Field

[0001] This invention relates to a method for assembling and disassembling a bidirectional clamping photoelectric switch. Background Technology

[0002] Currently, photoelectric switches are frequently used in power plants for distance signal detection. The installation of photoelectric switches often requires the use of brackets and other accessories. Due to the obstruction of these brackets and accessories, ordinary wrenches are often not conducive to disassembly. In addition, the fixing bolts of photoelectric switches are only 3mm thick, and ordinary wrenches are too thick to hold the fixing bolts, which can easily cause the photoelectric switch to shift its position when tightened. Furthermore, two wrenches are needed to hold the two fixing bolts on the photoelectric switch at the same time during disassembly and assembly, which restricts the operation. Summary of the Invention

[0003] The purpose of this invention is to provide a bidirectional clamping method for assembling and disassembling photoelectric switches.

[0004] The above objectives are achieved through the following technical solutions: A method for assembling and disassembling a bidirectional clamping photoelectric switch, the method comprising the following steps: (1) First, insert the inner side of the arch into the bracket, then put both sliding sleeves and the four-sided plate onto the photoelectric switch, and then slide the two sliding sleeves to slide towards the two fixing bolts; (2) Then rotate the sliding sleeve so that each side of its quadrangular plate corresponds to each side of the fixing bolt, insert the quadrangular plate into the fixing bolt, and after inserting the quadrangular plates of both sliding sleeves into the fixing bolt, keep this position unchanged. (3) Twist the adjusting screw to make the pressure plate move downward until the top of the vertical end of the bracket is released. At this time, the device has achieved the fixed position. Then, hold the two sliding sleeves with both hands and rotate them to tighten the two fixing bolts at the same time.

[0005] The method for assembling and disassembling a bidirectional clamping photoelectric switch includes an adjusting screw threadedly connected to the arch of the arched plate, a pressure plate rotatably connected to the bottom of the adjusting screw, support rings fixed on both sides of the lower end of the arched plate, a sliding sleeve slidably connected inside the support ring, and the end of the sliding sleeve fixed to the quadrangular plate.

[0006] The aforementioned bidirectional clamping photoelectric switch assembly and disassembly method includes a plurality of hand grips fixed on the outer circumferential surface of the sliding sleeve.

[0007] The aforementioned bidirectional clamping method for assembling and disassembling a photoelectric switch includes a support ring that is a three-quarters circular ring structure.

[0008] The beneficial effects of this invention are: 1. The present invention can clamp the device on the bracket, and adjust the position of the device to align it with the fixing bolt of the photoelectric switch, so that the position of the photoelectric switch can remain unchanged when the fixing bolt is tightened, thus preventing the position of the photoelectric switch from changing when the fixing bolt is tightened.

[0009] 2. By setting two sliding sleeves, each with a four-sided plate fixed at one end, the two four-sided plates are respectively fitted onto two fixing bolts, which can be operated with both hands and tightened simultaneously. Attached Figure Description

[0011] Reference Figures 1-3 A method for assembling and disassembling a bidirectional clamping photoelectric switch, the method comprising the following steps: (1) First, insert the inner side of the arch into the bracket, then put both sliding sleeves and the four-sided plate onto the photoelectric switch, and then slide the two sliding sleeves to slide towards the two fixing bolts; (2) Then rotate the sliding sleeve so that each side of its quadrangular plate corresponds to each side of the fixing bolt, insert the quadrangular plate into the fixing bolt, and after inserting the quadrangular plates of both sliding sleeves into the fixing bolt, keep this position unchanged. (3) Twist the adjusting screw to make the pressure plate move downward until the top of the vertical end of the bracket is released. At this time, the device has achieved the fixed position. Then, hold the two sliding sleeves with both hands and rotate them to tighten the two fixing bolts at the same time.

[0012] A method for assembling and disassembling a bidirectional clamping photoelectric switch includes an arched plate 2. An adjusting screw 1 is threadedly connected to the arch of the arched plate. A pressure plate 3 is rotatably connected to the bottom of the adjusting screw. The width D of the inner side of the arched plate's arch is slightly greater than the thickness of the vertical end of the support, typically by about 0.3 mm. This ensures that the inner side of the arch is clamped onto the support without wobbling. The adjusting screw is then turned, and the width of the pressure plate at the bottom of the adjusting screw is slightly less than the width D of the inner side of the arch, typically by about 0.3 mm. This prevents the pressure plate from rotating when the adjusting screw is turned, allowing for vertical up-and-down movement. Support rings 4 are fixed to both sides of the lower end of the arched plate. Each support ring is a three-quarter ring structure. A sliding sleeve 7 is slidably connected inside the support ring. The end of the sliding sleeve is fixed to a square-shaped plate 6. The square-shaped plate is a hexagonal ring structure with the two lower edges cut off. This structural design allows both the sliding sleeve and the square-shaped plate to be fitted onto the photoelectric switch.

[0013] The aforementioned bidirectional clamping photoelectric switch assembly and disassembly method includes a plurality of hand grips 5 fixed on the outer circumferential surface of the sliding sleeve.

[0014] Working principle: Refer to Figure 4 In use, first insert the inner side of the arch into the bracket 9, then place both sliding sleeves and the four-sided plate onto the photoelectric switch 8. Then slide the two sliding sleeves towards the two fixing bolts. Next, rotate the sliding sleeves so that each side of the four-sided plate corresponds to each side of the fixing bolt. Insert the four-sided plate into the fixing bolt. After inserting the four-sided plates of both sliding sleeves into the fixing bolt, keep this position unchanged and turn the adjusting screw to move the pressure plate downward until it releases the top of the vertical end of the bracket. At this time, the device achieves position fixation. Then, hold the handles of the two sliding sleeves with both hands and slide and rotate them to simultaneously tighten the two fixing bolts. Because the device achieves position fixation, the four-sided plate is inserted into the fixing bolt, and the device will not move up and down. When the sliding sleeve rotates, it can only move horizontally, which can ensure that the photoelectric switch position remains unchanged when tightening.
