Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a proximity switch wrench. Background Art

[0002] A wrench is a common tool used to tighten or loosen nuts, bolts and other fasteners. When installing and disassembling proximity switches, a spanner is used. A spanner is a spanner with an adjustable opening size, also known as an adjustable spanner or an open-end spanner, and is used to tighten or loosen screws, nuts and bolts of various sizes.

[0003] When installing and removing the proximity switch, the existing proximity switch wrench needs to frequently adjust the roller of the adjustable spanner to ensure that the spanner groove matches the threaded lock buckle on the outer side of the proximity switch. When adjusting, the spanner groove needs to be disengaged from the threaded lock buckle and then adjusted. After the adjustment is completed, the spanner groove needs to be matched with the threaded lock buckle again, which is time-consuming and labor-intensive. Secondly, the handle of the conventional adjustable spanner and the spanner groove are located in the same straight line, resulting in its length being too long. When the proximity switch is installed in a narrow position, the conventional adjustable spanner cannot be adjusted, limiting its scope of use.

[0004] Therefore, we provide a proximity switch wrench. Utility Model Content

[0014] 1. The proximity switch wrench, through the setting of the handle and the fixing seat, can adjust the angle between the handle and the fixing seat according to the installation environment of the proximity switch when installing and disassembling the proximity switch. After the adjustment is completed, the lock nut is abutted against one side of the fixing seat to lock the handle angle. When using the wrench, it is no longer restricted by the installation environment, and the angle between the handle and the fixing seat can be adjusted as needed to adapt to different angles or narrow installation positions.

[0015] 2. Through the setting of the adjusting rod and the connecting rod, when installing and disassembling the proximity switch, the knob can be manually rotated, and the knob drives the adjusting rod to rotate, thereby driving the outer double-thread buckle to rotate synchronously. At this time, the two sets of sliding blocks on the outer side will move inward or outward synchronously, and the sliding blocks indirectly drive the slot seat to move, thereby achieving the purpose of changing the size of the slot. When adjusting, there is no need to disengage the slot seat from the thread lock buckle, and it can be adjusted directly manually without repeated positioning, saving time and labor.

[0023] Furthermore, rotating rods 11 are welded on both sides of the upper end of the handle 1, and a locking nut 12 is provided on the outer threaded sleeve of one group of rotating rods 11. A rotating seat 21 is welded on the lower end of the fixed seat 2, and the rotating rods 11 are rotatably installed on the inner side of the rotating seat 21, and the locking nut 12 abuts against one side of the rotating seat 21. The locking nut 12 is used to fix the rotating rod 11, and indirectly fixes the angle between the handle 1 and the slot seat 6.

[0024] Furthermore, a slide groove 22 is provided inside the fixed seat 2, and the slide groove 22 provides a sliding path for the sliding block 42. Through holes 23 are provided on both sides of the slide groove 22, and the adjustment rod 5 is rotatably installed inside the through hole 23. The knob 51 can be used to drive the adjustment rod 5 to rotate inside the through hole 23.

[0025] Furthermore, a guide groove 31 is opened at the upper end of the T-frame 3, a guide block 41 is welded to the upper end of the connecting rod 4, and the groove seat 6 is welded to the upper end of the guide block 41. When the guide block 41 moves, it will drive the groove seat 6 to move synchronously, and the guide block 41 is slidably installed inside the guide groove 31. When the connecting rod 4 slides, it drives the guide block 41 to slide inside the guide groove 31, and the guide groove 31 provides a sliding path for the guide block 41.

[0026] Furthermore, a sliding block 42 is welded to the lower end of the connecting rod 4, and the sliding block 42 is slidably installed inside the slide groove 22. A threaded hole 421 is penetrated through the side of the sliding block 42. When the adjusting rod 5 rotates, it can drive the sliding block 42 to slide inside the slide groove 22.

[0027] Furthermore, a knob 51 is welded to one end of the adjusting rod 5, a double-threaded buckle 52 is provided on the outer side of the adjusting rod 5, and the adjusting rod 5 is threadedly installed inside the threaded hole 421 through the double-threaded buckle 52, and two groups of sliding blocks 42 are sleeved on the outer side of the double-threaded buckle 52. When the adjusting rod 5 drives the double-threaded buckle 52 to rotate, the two groups of sliding blocks 42 can be driven to move inward or outward synchronously.

[0028] Furthermore, a threaded buckle 53 is provided on the outside of the adjusting rod 5 and at the other end of the adjusting rod 5. A fixing nut 54 is provided on the outer thread of the threaded buckle 53, and the fixing nut 54 abuts against one side of the fixing seat 2. The fixing nut 54 serves to fix the adjusting rod 5. When the fixing nut 54 abuts against one side of the fixing seat 2, the adjusting rod 5 will be unable to rotate.

[0029] Working principle: First, move a proximity switch wrench to the working position. In the first step, when installing or removing the proximity switch, the angle between the handle 1 and the slot seat 6 can be adjusted according to the installation position of the proximity switch. In the second step, manually loosen the locking nut 12. At this time, the rotating rod 11 and the rotating seat 21 are in an active state. Manually adjust the angle between the handle 1 and the slot seat 6. After the adjustment is completed, tighten the locking nut 12 to make it abut against one side of the rotating seat 21 again. At this time, the angle between the handle 1 and the slot seat 6 is fixed. In the third step, place the slot seat 6 on the outside of the threaded lock buckle on the outside of the proximity switch. There is no need to move the position of the slot seat 6. Manually rotate the knob 51 The knob 51 drives the adjusting rod 5 to rotate. At this time, the double-threaded buckle 52 on the outside of the adjusting rod 5 is in a threaded matching state with the sliding block 42. When the adjusting rod 5 rotates, the sliding block 42 slides to both sides synchronously, thereby interfering with and indirectly driving the slot seat 6 to move until the slot seat 6 fits with the threaded lock. After the position adjustment of the slot seat 6 is completed, the fixing nut 54 is manually tightened. At this time, the adjusting rod 5 will be fixed and cannot rotate, thereby indirectly reaching the position of the fixed slot seat 6. In the fourth step, the slot seat 6 is rotated by twisting the handle 1, thereby driving the threaded lock to be synchronously unscrewed, thus completing the use process of a proximity switch wrench.
