Screws are arranged at the corner positions on the surface of the guide rail, and a screw groove is installed at one end inside the screw. The bottom end of the screw groove extends outside the guide rail. A guide block is fixed at the center position of the bottom end of the signal isolator body";

[0004] In the above device, the connection between the signal isolator and the circuit still uses a bolt-fixed connection. This connection method is relatively inconvenient to operate and requires tools for connection, so the quick-connect effect cannot be achieved. At the same time, due to the bolt connection method, the circuit is prone to looseness and detachment, thus affecting the use of the signal isolator. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a quick-connect signal isolator, which solves the problems that currently exist in the connection of the signal isolator to the circuit, that is, tools are required, so the quick-connect effect cannot be achieved, and at the same time, the connection between the circuit and the isolator is prone to looseness and detachment, affecting the use of the isolator.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A quick-connect signal isolator, including an isolator body, and a display screen is arranged on the front surface of the isolator body;

[0007] A quick-connect socket is arranged on one side of the upper surface of the isolator body. A quick-connector is arranged above the quick-connect socket. A circuit is arranged inside the quick-connector. An elastic sleeve is arranged on the upper surface of the quick-connector. A locking nut is arranged outside the elastic sleeve;

[0008] The quick connector includes an adjusting block, a plug, a limiting post and an upper guide seat. The plug is fixedly installed below the adjusting block. The limiting post is fixedly installed on the outer surface of the plug. The upper guide seat is fixedly installed below the plug.

[0009] As a preferred technical solution of the present utility model, the quick connection seat includes a housing, a limiting groove and a communication mechanism. The limiting groove is formed on the inner surface of the housing. The communication mechanism is fixedly installed below the inner part of the housing.

[0010] As a preferred technical solution of the present utility model, the communication mechanism includes a mounting seat, a lower guide seat and a return spring. The lower guide seat is fixedly installed on the upper surface of the mounting seat. The return spring is fixedly installed below the mounting seat.

[0011] As a preferred technical solution of the present utility model, the display screen is fixedly installed with the isolator body. The quick connection seat is located on the upper surface and the lower surface of the isolator body and is evenly arranged on the surface of the isolator body. Thread grooves are formed on the outer surface of the elastic sleeve. The locking nut is threadedly connected with the elastic sleeve.

[0012] As a preferred technical solution of the present utility model, the plug is movably installed with the quick connection seat. Two groups of limiting posts are arranged on both sides of the outer surface of the plug. The limiting posts are slidably connected with the quick connection seat.

[0015] Compared with the prior art, the present utility model provides a quick-connect signal isolator, which has the following beneficial effects:

[0016] The quick-connect signal isolator has limiting grooves opened on both inner sides of the housing. The outer surface of the plug is fixedly installed with limiting posts, and the limiting grooves are slidably connected to the limiting posts. Therefore, when connecting the quick connector and the quick-connect socket, only need to align the limiting posts with the limiting grooves and then rotate the plug to insert the plug into the interior of the housing. At the same time, the clamping groove connected above the end of the limiting groove can fix the limiting posts inside it. Therefore, the connection between the circuit and the isolator is more convenient when the device is in use. At the same time, since an elastic sleeve is installed on the surface of the adjusting block above the plug and the elastic sleeve is made of metal, after feeding the circuit into the interior of the elastic sleeve, rotating the locking nut can make the elastic sleeve clamp and fix the circuit, effectively avoiding loosening and falling off between the circuit and the isolator. And because a return spring is installed below the communication mechanism inside the housing, under the reaction force of the return spring, the lower guide seat and the upper guide seat can be more closely attached, thus ensuring the stability of the connection between the circuit and the isolator and also ensuring that the limiting posts are fixed in the clamping grooves at the ends of the limiting grooves.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , in this embodiment: A quick-connect signal isolator includes an isolator body 1, and a display screen 2 is arranged on the front surface of the isolator body 1;

[0026] On one side of the upper surface of the isolator body 1, a quick-connect socket 3 is arranged, a quick-connect head 4 is arranged above the quick-connect socket 3, a circuit 5 is arranged inside the quick-connect head 4, an elastic sleeve 6 is arranged on the upper surface of the quick-connect head 4, and a locking nut 7 is arranged outside the elastic sleeve 6;

[0027] The quick-connect head 4 includes an adjusting block 41, a plug 42, a limiting post 43 and an upper guide seat 44. The plug 42 is fixedly installed below the adjusting block 41, the limiting post 43 is fixedly installed on the outer surface of the plug 42, and the upper guide seat 44 is fixedly installed below the plug 42.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, the quick-connect socket 3 includes a housing 31, a limiting groove 32 and a connecting mechanism 33. The limiting groove 32 is opened on the inner surface of the housing 31, and the connecting mechanism 33 is fixedly installed below the inner part of the housing 31.

[0029] In the above embodiment, through the cooperation of the housing 31 and the limiting groove 32 of the quick-connect socket 3, a convenient connection and fixation with the quick-connect head 4 can be achieved, and the connecting mechanism 33 installed inside the housing 31 can cooperate with the quick-connect head 4 to realize the connection between the circuit 5 and the isolator body 1.

[0030] Furthermore, the limiting grooves 32 are located on both sides inside the housing 31 and are arranged in a mirror image. A through hole is arranged at the bottom of the housing 31, and a lead of the connecting mechanism 33 is connected below and passes through the through hole to be fixedly connected with the isolator body 1.

[0031] By opening a through hole below the inner part of the housing 31, the lead used by the connecting mechanism 33 can pass through the quick-connect socket 3 to be connected with the isolator body 1, so as to cooperate with the quick-connect head 4 to realize the connection between the circuit 5 and the isolator body 1.

[0032] Please refer to Figure 3 and Figure 4, in this embodiment, the connection mechanism 33 includes a mounting base 331, a lower guide base 332 and a return spring 333. The lower guide base 332 is fixedly installed on the upper surface of the mounting base 331, and the return spring 333 is fixedly installed below the mounting base 331.

[0033] In the above embodiment, the lower guide base 332 can be installed and fixed through the mounting base 331 of the connection mechanism 33. At the same time, under the reaction force of the return spring 333, the mounting base 331 can be pushed to drive the lower guide base 332 to closely fit with the quick connector 4.

[0034] Specifically, the return spring 333 is fixedly connected between the mounting base 331 and the housing 31, and the lower guide base 332 and the mounting base 331 are concentrically arranged.

[0035] Through the connection between the return spring 333 and the housing 31, one end of the return spring 333 is in a non-rotating state. Since the diameter of the mounting base 331 is smaller than the inner diameter of the housing 31, the mounting base 331 can drive the lower guide base 332 to move inside the housing 31 under the action of the return spring 333.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 5 , in this embodiment, the plug 42 is movably installed with the quick connection socket 3. There are two groups of limit posts 43 located on both sides of the outer surface of the plug 42. The limit posts 43 are slidably connected with the quick connection socket 3. The elastic sleeve 6 is fixedly installed on the upper surface of the adjusting block 41.

[0037] In the above embodiment, the plug 42 can be driven into the quick connection socket 3 under the action of the adjusting block 41. With the cooperation of the elastic sleeve 6 installed above the adjusting block 41 and the locking nut 7, the wire 5 can be clamped and fixed inside the elastic sleeve 6, thereby ensuring the connection stability between the wire 5 and the plug 42 and preventing the wire 5 from loosening and falling off.

[0038] It should be added that the display screen 2 is fixedly installed with the isolator body 1. The quick connection sockets 3 are located on the upper surface and the lower surface of the isolator body 1 and are evenly arranged on the surface of the isolator body 1. Thread grooves are formed on the outer surface of the elastic sleeve 6, and the locking nut 7 is threadedly connected with the elastic sleeve 6.

[0039] Working principle and usage process of the present utility model: After the operator feeds the circuit 5 into the interior of the elastic sleeve 6, passes through the adjusting block 41 and connects with the plug 42, by rotating the locking nut 7, since the outer surface of the elastic sleeve 6 is provided with a thread groove, the locking nut 7 moves upward on the surface of the elastic sleeve 6 to clamp and fix the circuit 5 inside to prevent it from falling off. After the circuit 5 is connected, after aligning the limiting post 43 on the outer side of the plug 42 with the starting port of the limiting groove 32 and feeding it into the limiting groove 32, by rotating the plug 42 through the adjusting block 41, the limiting post 43 rotates and moves downward into the clamping groove at the end of the limiting groove 32. During the downward movement of the plug 42, the upper guide seat 44 presses downward on the lower guide seat 332, and under the reaction force of the return spring 333, the lower guide seat 332 and the upper guide seat 44 remain in close fit to form a path. At this time, the limiting post 43 is fixed in the clamping groove at the end of the limiting groove 32. When disassembly is required, simply press down on the quick connector 4 to make the limiting post 43 enter the limiting groove 32, and then the adjusting block 41 can be rotated in the reverse direction to conveniently separate the quick connector 4 from the quick connection base 3.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
