[0023] 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.

[0024] This relay protector offers two technical solutions using an auxiliary fixing structure:

[0025] like Figure 1-4 The first embodiment is shown: it includes an electrical cabinet door 1 and a relay protector body 2. Auxiliary fixing structures are provided on both the left and right sides of the relay protector body 2, and the relay protector body 2 is installed at the mounting holes on the electrical cabinet door 1 through the auxiliary fixing structures. The auxiliary fixing structures include:

[0026] The positioning and fixing component 4 includes a pressure plate 41. A groove 42 is provided on the back of the pressure plate 41. A T-shaped positioning rod 43 is slidably connected to the left side of the inner wall of the groove 42. The T-shaped positioning rod 43 passes through the pressure plate 41 and extends to the outside of the pressure plate 41. A return spring 44 is sleeved on the surface of the T-shaped positioning rod 43 inside the pressure plate 41. A rotating rod 45 is rotatably connected to the front of the inner wall of the groove 42. A top block 46 for pushing the T-shaped positioning rod 43 is fixedly connected to the surface of the rotating rod 45. The top block 46 is elliptical in shape, and the left tip of the top block 46 is cut off to form a plane. The top block 46 and the rotating rod 45 are eccentrically connected, and the rotating rod 45 is close to the right tip of the top block 46. Multiple fixing and positioning holes 47 for cooperating with the T-shaped positioning rod 43 are provided at equal intervals on the left side of the inner wall of the receiving groove 31.

[0027] When installing the main body 2 of the relay protector, it is fixed to the electrical cabinet door 1 by the fixing and positioning component 4. The fixing and positioning component 4 is easy and quick to operate and has a compact structure, which reduces the space occupied and is suitable for electrical cabinet doors of different thicknesses, thus improving the convenience of using the device.

[0028] like Figure 2 and 4The second implementation method is shown. The main difference from the first implementation method is that the storage component 3 is set on the side of the relay protector body 2 to store the positioning and fixing component 4, thereby reducing the space occupied. The storage component 3 includes a storage groove 31 opened on the right side of the electrical cabinet door 1. The top and bottom of the inner wall of the storage groove 31 are provided with sliding grooves 32. The inner surfaces of the upper and lower sliding grooves 32 are slidably connected with square blocks 33. The opposite sides of the upper and lower square blocks 33 are fixedly connected with connecting short shafts 34. The back of the inner wall of the storage groove 31 is provided with a storage positioning hole 35. The positioning and fixing component 4 is rotatably connected to the opposite sides of the upper and lower connecting short shafts 34.

[0029] Before the main body 2 of the protector is installed, the fixed positioning component 4 can be stored in cooperation with the storage component 3, thereby reducing the space occupied by the auxiliary fixing structure and improving the aesthetics.

[0030] In use, insert the relay protector body 2 into the mounting hole on the electrical cabinet door 1, then rotate the pressure plate 41. The pressure plate 41 rotates so that one end of the T-shaped positioning rod 43 located outside the pressure plate 41 faces the inside of the storage slot 31. Then push the pressure plate 41 to move, so that the pressure plate 41 presses against the electrical cabinet door 1. After pressing, rotate the rotating rod 45. The rotating rod 45 rotates so that the top block 46 rotates. The top block 46 rotates to the plane of the cut-off point and contacts the T-shaped positioning rod 43, thereby pushing the T-shaped positioning rod 43 to move, so that the end of the T-shaped positioning rod 43 enters the corresponding fixed positioning hole 47, thereby positioning the pressure plate 41 and fixing the relay protector body 2. In addition, when storing the positioning and fixing component 4, first loosen the positioning, then move the pressure plate 41, then rotate the pressure plate 41 so that the pressure plate 41 enters the storage slot 31. Finally, rotate the rotating rod 45 so that the end of the T-shaped positioning rod 43 enters the storage positioning hole 35.
