[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Figures 1-4The present invention is an embodiment of the present invention. The specific problem addressed by this embodiment is that electrical equipment needs to be positioned for fault detection during use. With the continuous development of science and technology, people have increasingly higher requirements for the manufacturing process of fault detection devices for electrical equipment. The most common fault detection device used for electrical equipment is the electrical equipment fault detector. The detection head of the electrical equipment fault detector in the prior art is mostly directly exposed to the outside, which cannot be well protected, shortening the service life of the device, and having poor impact resistance and explosion resistance. It is not suitable for different environments and has low practicality. That is, the existing technical problem is that the detection head of the fault detector is directly exposed to the outside, causing friction with other tools and causing wear. Based on the utility patent application number 202121012071.5, it describes a fault detection device for electrical equipment with a sleeve plate, but the sleeve plate does not have a corresponding position fixing device. Even if the sleeve plate wraps the detection probe 4, it does not have a limiting structure. When subjected to external force, the sleeve plate easily breaks away from the detection probe 4, thereby causing the detection probe 4 to be exposed again. The problem of friction between the detection head and other storage tools is not completely solved. That is, the present invention utilizes the buckle cap 5 installed on the detector body 1 to effectively wrap the detection probe 4, thereby reducing the contact with other storage items during the storage process and thus reducing the friction that causes wear and even scratches on the detection probe 4. Under the wrapping of the buckle cap 5, the protection of the detection probe 4 is enhanced and its effective use time is extended.

[0027] The present invention describes an electrical equipment fault detection device that is specifically based on a detector body 1. A display screen 2 and an adjustment button 3 for controlling its on and off state are installed on the detector body 1. The detector body 1, the display screen 2 and the adjustment button 3 are the same as those described in the existing patent and are not changed in this embodiment. A detection probe 4 is installed on the upper end of the detector body 1. The detection probe 4 is adjustable and is provided with a buckle cap 5 installed on the detector body 1. The buckle cap 5 is set to slide up and down or flip up and down along the detector body 1, so that the buckle cap 5 can adapt to the detector body 1 when it is in use or stored.

[0028] The buckle cap 5 includes a sleeve 51 that rotates on the detector body 1, and a rotating shaft 52 is installed on the left and right ends of the detector body 1. The rotating shaft 52 extends from the sleeve 51 and passes through the sleeve 51. The sleeve 51 is provided with a through groove 53 that is adapted to the diameter of the rotating shaft 52 at the position where the rotating shaft 52 passes through. The length of the through groove 53 is greater than the diameter of the rotating shaft 52. A cap 56 that is adapted to the position of the detection probe 4 is installed on the sleeve 51 structure. The internal cavity of the cap 56 is adapted to the shape of the detection probe 4. An inner groove 54 is opened on the rotating shaft 52. There are two inner grooves 54 symmetrically arranged on the rotating shaft 52 in the axial direction. The difference between the length of the through groove 53 and the length of the diameter of the rotating shaft 52 is compensated by the plug plate 55. The buckle cap 5 establishes a basis for wrapping the detection probe 4 without hindering the use of the detection probe 4, and can, when the detection probe 4 is in a single state, produce an unchanged position relative to the detection body through the plug plate 55, thereby enhancing the stability of the buckle cap 5 relative to the detection probe 4 and stabilizing the existing state of the buckle cap 5. The plug plate 55 includes a handheld end 551 and an inner plate 552 installed at the lower end of the handheld end 551 for plugging into the through-slot 53. The inner plate 552 is connected to the rotating shaft 52 and generates relative movement relative to the through-slot 53 through the rotating shaft 52. The thickness of the inner plate 552 is equal to the thickness of the sleeve plate 51. The handheld end 551 extends outside the through-slot 53. The handheld end 551 is symmetrically provided with handheld slots in the front and back. The opening length of the through-slot 53 is adapted to the moving distance of the cap 56 to break away from the contact with the detection end and the moving distance when it is buckled on the detection end.

[0029] The rotating shaft 52 includes a mounting shaft 521 mounted on the detector body 1, and one end of the mounting shaft 521 is connected to an adjusting shaft 523 connected to the inner panel 552 through a telescopic shaft 522. The structure of the adjusting shaft 523 is the same as that of the mounting shaft 521 and is set with the same diameter as the mounting shaft 521. The maximum elongation length of the telescopic shaft 522 is greater than the difference between the thickness of the sleeve plate 51 and the extension length of the mounting shaft 521 in the through groove 53. The telescopic shaft 522 is rotatably connected to the mounting shaft 521. When the sleeve plate 51 needs to be rotated, first drag the adjusting shaft 523 to stretch the telescopic shaft 522, and then rotate the telescopic shaft 522 and the adjusting shaft 523 to drive the plug plate 55 to rotate as a whole. After the rotating shaft 52 moves to a predetermined position in the through groove 53, the inner panel 552 is pushed into the through groove 53 to complete the direction adjustment of the sleeve plate 51.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
