Description

Technical Field

[0001] The utility model relates to the technical field of signal isolators, in particular to a quick-connect signal isolator. Background Art

[0002] An isolator is a device that uses the linear optocoupler isolation principle to convert input signals into outputs. The input, output and working power supply are isolated from each other, and it is particularly suitable for use with equipment and instruments that require electrical isolation. Isolators, also known as signal isolators, are an important component of industrial control systems. Signal isolators are generally directly connected to the periphery of the guide rail for use, and because the guide rail is long, multiple groups of signal isolators can be installed on one group of guide rails. However, since the specifications of the slots at the bottom of the signal isolator that connect to the guide rails are fixed, it is quite inconvenient to install if you encounter guide rails of different specifications or in different environments. For this reason, we propose a quick-connect signal isolator. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a quick-connect signal isolator.

[0004] The technical solution adopted by the utility model to solve the technical problem is a quick-connect signal isolator, comprising a base, the top surface of the base is plugged with a signal isolator body, and the bottom surface of the base is provided with a groove for connection, the inner peripheral surface of the groove is provided with a slide groove for adjustment, and a slide seat for adjustment is slidably installed inside the slide groove, a slide block for support is mounted on a side of the slide seat located inside the groove, and an inclined block for fixing is integrally constructed on the outer wall surface of the slide block, a sliding hole connected to the groove is provided inside the base, and an inclined plate corresponding to the inclined block is slidably installed inside the sliding hole, and a guide rail for support is clamped between the inclined plate and the inclined block;

[0005] A screw connected to the sliding seat is rotatably installed on the inner side of the slide groove, and a worm wheel for transmission is sleeved on one end of the screw located on the inner side of the base. A worm meshing with the worm wheel is rotatably installed on the inner side of the base, and a knob connected to the worm wheel for transmission is rotatably installed on the outer wall surface of the base.

[0006] By adopting the above technical solution, when installing the signal isolator, the signal isolator body can be conveniently plugged into the top of the base, and then the sliding seat that slides in the slide groove in the groove at the bottom of the base is moved, so that the sliding seat can drive the slider to slide inside the groove, and at the same time, the slider conveniently drives the inclined block to approach the inclined plate on the inner wall surface of the groove, so as to facilitate the adjustment of the distance between the inclined block and the inclined plate, and then the base can be clamped on the outer periphery of the guide rail, so as to facilitate the installation of the signal isolator, and it can be installed on the outer periphery of guide rails of different specifications;

[0007] When it is necessary to adjust the position of the slider in the groove, the knob on the surface of the base can be rotated so that the knob can drive the worm on the inside of the base to rotate, so that the worm can mesh with the worm wheel and drive the worm wheel to rotate. Then the worm wheel can easily drive the screw in the slide groove inside the base and the groove to rotate, so that the screw can be screwed with the slide seat, so that the slide seat can move along the slide groove, and then the slider and the inclined block can be moved, so that the distance between the inclined block and the inclined plate can be adjusted, which is convenient for the subsequent installation of the signal isolator, and the adjustment is simple and convenient.

[0008] Specifically, a pull rod drivingly connected to the inclined plate is slidably mounted on the outer side wall surface of the base.

[0009] By adopting the above technical solution, the pull rod can conveniently pull the inclined plate in the sliding hole inside the base to slide and move, so that the base is easy to disassemble and assemble.

[0010] Specifically, a spring for pushing the inclined plate to slide is installed inside the sliding hole.

[0011] By adopting the above technical solution, the spring in the sliding hole facilitates the movement of the inclined plate, so that one end of the inclined plate can extend out of the sliding hole and enter the groove, and facilitates the cooperation with the inclined block, so that the base can be clamped on the outer periphery of the guide rail.

[0012] Specifically, the top surface of the slider is integrally formed with convex strips that fit and connect with the inner wall of the groove, and there are multiple groups of convex strips.

[0013] By adopting the above technical solution, the convex strip on the top of the slider is conveniently connected to the groove on the inner wall surface of the groove, which is convenient for improving the stability of the slider inside the groove when sliding.

[0014] Specifically, the inner peripheral surface of the groove, the top surface of the inclined block and the top surface of the inclined plate are all bonded with rubber pads for protection.

[0015] By adopting the above technical solution, the rubber pad has certain anti-slip and protective properties, which is convenient for reducing the damage caused by friction between the guide rail and the inclined block and the inclined plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the signal isolator body, groove, slide groove, slide seat, slider, inclined block, guide rail, slide hole and inclined plate, can conveniently insert the signal isolator body on the top of the base when installing the signal isolator, and then move the slide seat that slides in the slide groove in the groove at the bottom of the base, so that the slide seat can drive the slider to slide inside the groove, and at the same time, the slider can conveniently drive the inclined block to approach the inclined plate on the inner wall surface of the groove, so as to facilitate the adjustment of the distance between the inclined block and the inclined plate, and then the base can be clamped on the outer periphery of the guide rail, which is convenient for installing the signal isolator, and can be installed on the outer periphery of guide rails of different specifications.

[0018] 2. The technical solution of the present application adopts the design of knob, screw, worm wheel and worm. When the position of the slider in the groove needs to be adjusted, the knob on the surface of the base can be rotated so that the knob can drive the worm on the inner side of the base to rotate, so that the worm can mesh with the worm wheel and drive the worm wheel to rotate. Then the worm wheel can conveniently drive the screw in the slide groove inside the base and the groove to rotate, so that the screw can be screwed with the slide seat, so that the slide seat can move along the slide groove, and then the slider and the inclined block can be displaced, so as to facilitate the adjustment of the distance between the inclined block and the inclined plate, and facilitate the subsequent installation of the signal isolator, and the adjustment is simple and convenient.
