Description

Technical Field

[0001] The utility model relates to the technical field of proximity switch brackets, in particular to a bracket used for installing proximity switches. Background Art

[0002] A proximity switch refers to a device used to detect the approach or departure of an object. It includes a sensor and a switch component. The sensor of a proximity switch usually works according to different principles, such as photoelectric, inductance, ultrasonic, etc. The sensor detects whether an object is approaching by sensing changes in certain characteristics of the object (such as changes in light, inductance, or reflection time of sound waves, etc.). When an object is detected approaching, the sensor will send a signal, pass the signal to the switch component, and then the switch will produce a corresponding action.

[0003] Existing proximity switch brackets usually adopt L-shaped brackets or U-shaped brackets. The L-shaped bracket is made of an L-shaped metal plate and can be fixed to the surface where the proximity switch needs to be installed by screws or welding. One side of the L-shaped bracket can be fixed to the surface, and the other side is used to fix the proximity switch. The U-shaped bracket is made of a U-shaped metal plate and can be fixed to the equipment or machine by screws or welding. The proximity switch can be placed at the bottom of the U-shaped bracket and fixed with screws. However, whether it is an L-shaped bracket or a U-shaped bracket, it needs to be fixed by welding when installing the proximity switch, which means that once the installation is completed, the position of the proximity switch can no longer be adjusted, which will cause some inconvenience, especially when the proximity switch needs to be repositioned or replaced.

[0004] Therefore, we provide brackets for mounting proximity switches. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The bracket for installing the proximity switch can be fixed on the inner side of the fixed rail through the setting of the support column and the fixed rail when installing the proximity switch, and then the base at the lower end of the support column is installed in a suitable position with bolts according to the installation position. It is no longer necessary to weld the bracket to the wall or the machine side, so that subsequent maintenance and replacement become more convenient.

[0015] 2. Through the setting of the adjusting rod and the movable rail, when installing the proximity switch, the base bolt can be installed in the approximate position, and then the guide block can be driven up and down by rotating the adjusting rod to change the vertical installation position of the proximity switch.

After the adjustment is completed, it can be fixed. Secondly, when the proximity switch needs to be temporarily adjusted, its vertical position can be directly changed by rotating the adjusting rod, and the lateral position of the proximity switch can be fine-tuned by sliding the movable rail, avoiding the limitation that the position cannot be adjusted after the proximity switch is installed on the traditional bracket. This structure provides greater flexibility and adjustment capabilities. It allows precise adjustment of the position during installation and maintenance, making the installation of the proximity switch more convenient and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the sliding buckle 42 rotates inside the bearing 33, and at the same time, the guide block 5 on the outside of the threaded buckle 43 slides inside the guide groove 11. The guide block 5 indirectly drives the fixed rail 6 to move up and down through the connecting column 52 until it moves to a suitable position for installing the proximity switch 8. After the adjustment is completed, tighten the locking nut 412, and the lower surface of the locking nut 412 abuts against the upper surface of the end cover 3 again. At this time, the adjusting rod 4 will Unable to rotate, the position of the guide block 5 is fixed, the third step, according to the installation position to adjust the relative position between the fixed rail 6 and the movable rail 7, if there is no need to unfold the movable rail 7, the proximity switch 8 can be directly clamped between the fixed rail 6 and the movable rail 7, the fourth step, if the length of the fixed rail 6 is not enough, at this time, the fixing nut 73 can be manually loosened, and the movable rail 7 is manually pulled to one side, and the movable rail 7 drives the upper end of the slider 71 to slide inside the slide groove seat 61. After the length is sufficient, the fixing nut 73 is tightened. At this time, the lower surface of the fixing nut 73 is re-contacted with the upper surface of the slide groove seat 61.
