[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in one embodiment of this utility model, an industrial automatic control instrument with plug-in installation is provided, including an instrument body 1, a limiting member 2, and an abutment member 4. The sleeve 201 of the limiting member 2 is slidably fitted onto the plug-in rod 102 of the instrument body 1. The sleeve 201 is fixedly connected to the annular baffle 107 inside the mounting groove 104 on the plug-in rod 102 by connecting screws 3, which facilitates the stable installation of the entire limiting member 2 onto the plug-in rod 102 and ensures that the limiting member 2 slides smoothly on the plug-in rod 102 through the sleeve 201. An elastic abutment plate 203 is fixedly connected to the sleeve 201. The end plate at the upper end of the elastic abutment plate 203... The end plate 204 has a slot 205 and is used to abut against the port position of the equipment insertion hole. During the installation process, the limiting member 2 is initially limited and fixed so that the abutment member 4 can be smoothly inserted into the limiting member 2, so that the two cooperate with each other and thus achieve stable installation of the instrument. The insertion groove formed between the sleeve 201 and the elastic abutment plate 203 is configured to cooperate with the conical abutment ring plate 401 on the abutment member 4. The conical abutment ring plate 401 is fixedly connected to the insertion rod 102 through the connecting sleeve 402. The limiting plate 403 on the conical abutment ring plate 401 is configured to cooperate with the slot 205.

[0025] When installing the instrument, first insert the plug rod 102 and the limiting member 2 together into the insertion hole on the equipment. Use the end plate 204 to initially fix and limit the limiting member 2 at the port of the insertion hole. Then continue to insert the plug rod 102. The plug rod 102 moves together with the abutment member 4, so that the conical abutment ring plate 401 is slowly inserted into the insertion groove between the sleeve 201 and the elastic abutment plate 203. During this process, the conical abutment ring plate 401 pushes against the elastic abutment plate 203, so that the elastic abutment plate 203 moves together with the anti-slip pad 206 and tightly abuts against the inner wall of the insertion hole. When the limiting plate 403 moves to the slot 205, rotate the plug rod 102, so that it rotates together with the abutment member 4, insert the limiting plate 403 into the slot 206, and limit and fix the abutment member 4 on the limiting member 2, so that the instrument is stably installed.

[0026] When disassembling the instrument, first rotate the limiting plate 403 out of the slot 205, and then pull it out. During the pulling process, the contact member 4 separates from the limiting member 2, so that the elastic contact plate 203 is no longer in close contact with the inside of the insertion hole, so that the insertion rod 102 and the limiting member 2 can be smoothly pulled out of the insertion hole, thus completing the quick disassembly of the instrument.

[0027] When the plug rod 102 is inserted into the position where the contact member 4 and the limiting member 2 cooperate, the connecting conductor 103 is electrically connected to the connector in the insertion hole on the equipment, thus completing a stable connection between the instrument and the equipment.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, the connecting screw 3 passes through the screw hole 202 at the corresponding position on the sleeve 201 and extends through the sliding groove 105 to the inner thread of the mounting groove 104, and is threaded into the threaded hole 108 on the annular baffle 107. The annular baffle 107 abuts against the support spring 106 installed inside the mounting groove 104, which facilitates the stable connection of the sleeve 201 and the annular baffle 107 together, thereby preventing the sleeve 201 from sliding off the plug rod 102. At the same time, the cooperation between the connecting screw 3 and the sliding groove 105 ensures that the annular baffle 107 can slide smoothly on the plug rod 102 along with the sleeve 201. The annular baffle 107 is slidably connected in the mounting groove 104, the connecting screw 3 is slidably connected in the sliding groove 105, and the support spring 106 is used to drive the sleeve 201 to slide back on the plug rod 102 after the external force is removed.

[0029] The plug rod 102 is provided with a connecting conductor 103, which is electrically connected to the instrument body 1. This facilitates the stable connection of the instrument and equipment together using the connecting conductor 103, ensuring stable operation. The plug rod 102 is fixedly connected to the plug socket 101 provided on the instrument body 1, which facilitates the stable connection of the two together.

[0030] like Figure 1 and Figure 3 As shown, in some embodiments, the elastic contact plate 203 mounted on the sleeve 201 is set as an inclined contact surface facing the insertion rod 102. The side of the elastic contact plate 203 that contacts the insertion hole on the equipment is fixedly connected with an anti-slip pad 206, which facilitates increasing the friction between the elastic contact plate 203 and the inner wall of the insertion hole, so that the limiting member 2 can be stably installed in the insertion hole, achieving stable installation of the instrument.

[0031] The elastic contact plates 203 form deformation grooves between each other, which facilitates the smooth deformation of the elastic contact plates 203 when pushed by the contact, thereby abutting against the inner wall of the insertion hole for stable and effective fixation. The insertion groove formed between the elastic contact plates 203 and the sleeve 201 is wider at the top and narrower at the bottom, which facilitates the smooth insertion of the conical contact ring plate 401 into the insertion groove. At the same time, it ensures that as the conical contact ring plate 401 extends, it can stably and effectively push the elastic contact plates 203. The width of the upper end of the insertion groove is less than the thickness of the upper part of the conical contact ring plate 401, thereby ensuring that the conical contact ring plate 401 can stably and effectively push the elastic contact plates 203. This allows the contact member 4 to cooperate with the limiting member 2 to stably install the instrument on the equipment and ensure the stable use of the instrument.

[0032] like Figure 4 As shown, in some embodiments, the cross-section of the tapered abutment ring plate 401 is an inverted tapered shape that is thinner at the top and lower bottom, which facilitates the formation of an inverted tapered abutment insertion component. This ensures that when it is inserted into the insertion groove between the sleeve 201 and the elastic abutment plate 203, it can continuously extend and push the elastic abutment plate 203, ensuring that the elastic abutment plate 203 deforms and moves together with the anti-slip pad 206, abutting against the inner wall of the insertion hole on the equipment. This allows the limiting member 2 to be stably installed in the insertion hole on the equipment, ensuring that the instrument is stably installed in the designated installation position on the equipment, and thus used stably.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
