[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2 and Figure 5 The utility model provides an embodiment: a coil assembly that is easy to assemble, including a shell 1, which is a component of the electromagnetic regulating valve and has a coil arranged inside. The technology is prior art, so it will not be described in detail. A mounting hole 2 is opened at the rear of the shell 1, which is mounted on the compressor by bolts. An auxiliary mechanism is provided on the rear side of the shell 1. The auxiliary mechanism includes an auxiliary component and a fixing component. The auxiliary component includes a positioning column 31, which can be inserted into a positioning hole or positioning groove pre-set in the inner wall of the compressor shell to ensure the position accuracy of the shell 1 during installation. The inner wall of the positioning column 31 slides and is connected A moving part 32 is connected, which controls the position of the moving block 35 by sliding on the inner wall of the positioning column 31. A sliding rod 33 is fixedly connected to the rear side of the moving part 32. The sliding rod 33 can be squeezed with the surface of the compressor, thereby driving the moving part 32 to slide on the inner wall of the positioning column 31, and driving multiple groups of sliding columns 36 and the moving block 35 to move through the guide groove 34, so that the moving block 35 drives the extrusion block 37 to squeeze the inner wall of the compressor, thereby fixing the outer shell 1, making it convenient for the operator to install the outer shell 1 with bolts, reducing the labor intensity of the workers and improving the work efficiency of the workers.

[0032] Furthermore, the slide rod 33 slides on the inner wall of the positioning column 31, and a guide groove 34 is opened on the outer side of the moving part 32, providing a precise sliding path for the moving block 35 and the slide column 36 thereon. The guide groove 34 is set to an L shape. Through the end of the L shape, after the moving block 35 is unfolded, the slide column 36 can be automatically limited, so that the moving block 35 always squeezes the inner wall of the compressor, which can improve the installation stability of the shell 1. The inner wall of the moving part 32 is slidably connected to the moving block 35, and is moved by driving the extrusion block 37 made of rubber material. The moving block 35 is fixedly connected with the slide column 36 on the upper and lower sides, which can limit the moving block 35 and control the moving direction of the moving block 35 at the same time. The slide column 36 slides on the inner wall of the guide groove 34.

[0033] Furthermore, an extrusion block 37 is provided on the outside of the movable block 35. The extrusion block 37 is made of rubber material. The rubber extrusion block 37 can fit tightly on the inner wall of the compressor casing, and utilizes the elastic deformation of the rubber to adapt to the surface shape and tiny irregularities of the inner wall of the casing, thereby increasing the contact area and friction with the inner wall, thereby effectively limiting the casing 1 and preventing it from being displaced during the installation process, providing a stable foundation for the operator's subsequent installation operations.

[0034] Reference Figure 2 and Figure 3 The fixing component includes a plug 41, which is fixedly connected to the outside of the extrusion block 37. A mounting groove 42 is provided on the side of the moving block 35 close to the extrusion block 37. The plug 41 is inserted into the inner wall of the mounting groove 42, and the extrusion block 37 is adhesively fixed to the outside of the moving block 35. The contact area between the extrusion block 37 and the moving block 35 is increased by the plug 41 and the mounting groove 42. There are multiple groups of moving blocks 35, and the multiple groups of moving blocks 35 are respectively arranged on the left and right sides of the guide groove 34, which can be limited from both sides, thereby improving the stability of the device.

[0035] Reference Figure 2 and Figure 4 The front corner of the moving part 32 is set as an inclined surface, which can cooperate with the inclined surface of the limiting part 51 to generate a lateral force to squeeze the limiting part 51 into the inner wall of the positioning column 31, thereby releasing the limit on the moving part 32. A limiting component is set on the inner wall of the positioning column 31. The limiting component includes a limiting part 51. The left rear part of the limiting part 51 is set as an inclined surface. Under the action of the elastic force of the compression spring 52, the moving part 32 can be blocked to prevent accidental touch, thereby improving the stability of the device. The limiting part 51 is slidably connected to the inner wall of the positioning column 31, and the outer side of the limiting part 51 is elastically connected to the positioning column 31 through the compression spring 52, which can provide elastic force for the limiting part 51.

[0036] Working principle: During use, when the coil assembly needs to be installed on the compressor, first align the positioning column 31 with the pre-set positioning hole or positioning groove on the inner wall of the compressor housing and insert it. During this process, the sliding rod 33 on the rear side of the moving part 32 will contact the surface of the compressor and be squeezed. The squeezing force exerted on the sliding rod 33 will cause the moving part 32 to slide in the positioning column 31.

[0037] When the moving part 32 moves, the slide 36 slides on the inner wall of the guide groove 34, driving the moving block 35 to slide out of the inner wall of the positioning column 31. When the slide 36 moves to the end of the L shape along the guide groove 34, the guide groove 34 will automatically limit the slide 36, so that the moving block 35 stops moving and always maintains a squeezing state on the inner wall of the compressor.

[0038] At this time, the rubber extrusion block 37 fixed on the outside of the moving block 35 will fit tightly against the inner wall of the compressor casing. The elastic deformation of the rubber enables it to adapt well to the surface shape and small irregularities of the inner wall of the casing, thereby increasing the contact area and friction with the inner wall, effectively limiting the casing 1 to prevent it from shifting during the installation process, and providing a stable foundation for the operator to use bolts to perform subsequent fixed installation operations on the casing 1 through the mounting holes 2, greatly facilitating the installation process, reducing the labor intensity of workers and improving work efficiency.

[0039] During this process, the inclined surface at the front corner of the moving part 32 contacts the inclined surface at the left rear part of the limiting part 51, which will generate a lateral force to squeeze the limiting part 51 into the inner wall of the positioning column 31, thereby releasing the limiting part 51 on the moving part 32, allowing the moving part 32 to slide smoothly.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
