[0029] 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.

[0030] See also Figures 1 to 6 In an embodiment of the present invention, an electrical instrument with a protective structure includes a multimeter 1 having a housing body 101. A raised edge 102 is formed in the middle of the outer side of the housing body 101. A rotation groove 103 is formed on one side of the raised edge 102. A protective component 2 is provided on the outer side of the raised edge 102. The protective component 2 is used to implement a protective operation on the front end of the housing body 101.

[0031] The protection component 2 includes a protection unit, a rotation and flip unit, and a support unit;

[0032] The protection unit cooperates with the raised edge 102 to provide scratch protection for the front end of the housing body 101;

[0033] The rotating and flipping unit is used to realize the effect of rotating and opening the protection unit and sleeved with the rear end of the housing body 101;

[0034] The supporting unit is used to provide support for the inclined placement of the housing body 101;

[0035] The protection unit includes a protection cover 201;

[0036] The protective cover 201 is sleeved on the outside of the raised edge 102 and is distributed at the front end of the housing body 101. The protective cover 201 can prevent external objects from scratching the display screen at the front end of the housing body 101.

[0037] The rotating and flipping unit includes a notch groove 202, a fixing plate 203, a rotating connecting block 204, and a T-shaped column 205;

[0038] The notch groove 202 is formed on one side of the protective cover 201, and the fixed plate 203 is fixed inside the notch groove 202. The rotating connecting block 204 is rotatably connected to the inside of the rotating groove 103. The T-shaped column 205 is fixed to one end of the rotating connecting block 204 and is rotatably connected to the fixed plate 203.

[0039] The protective cover 201 can be rotated horizontally with the rotating connecting block 204 as the center, thereby realizing the rotation and opening of the protective cover 201;

[0040] The protective cover 201 can be vertically rotated around the T-shaped column 205 , thereby realizing a flipping operation of the protective cover 201 and making the protective cover 201 rotatably sleeved on the rear end of the housing body 101 .

[0041] In this embodiment, when the multimeter 1 is stored daily, the protective cover 201 is sleeved on the front end of the housing body 1, and the inner side of the protective cover 201 is tightly fitted with the outer side of the raised edge 102, thereby protecting the front end of the housing body 1 and effectively preventing external objects from contacting the display screen at the front end of the housing body 1 and causing scratches on the display screen.

[0042] When the multimeter 1 is needed, the protective cover 201 only needs to be rotated horizontally 90 degrees around the connecting block 204, and then the protective cover 201 is flipped vertically 180 degrees around the T-shaped column 205. At this time, the opening of the protective cover 201 faces the rear end of the housing body 101. Then, the protective cover 201 is rotated horizontally 90 degrees towards the rear end of the housing body 101 around the connecting block 204. At this time, the protective cover 201 is sleeved on the rear end of the housing body 1 and fits tightly with the outer side of the raised edge 102. In this way, the front end of the housing body 101 is exposed, making it easier to perform measurement operations. At the same time, the protective cover 201 will not interfere with the use of the multimeter 1.

[0043] It should also be noted that there is friction between the protective cover 201 and the raised edge 102, which can ensure the stability of the protective cover 201. In addition, a structure for storing measuring pens and wiring harnesses can be set on the inside of the protective cover 201, such as a mesh bag, to store multimeter accessories.

[0044] Please refer to Figures 1 to 6 , the support unit includes a receiving slot 206 and a diagonal support plate 207;

[0045] The receiving groove 206 is provided on the outside of the end of the protective cover 201 away from the housing body 101, and the diagonal support plate 207 is rotatably connected to the inner side of the receiving groove 206;

[0046] When the protective cover 201 is sleeved on the rear end of the shell body 101 , the diagonal support plate 207 is rotated to an inclined state to support the shell body 101 in an inclined position.

[0047] In this embodiment: when the protective cover 201 is sleeved on the front end of the shell body 1, the storage groove 206 is open and the end of the diagonal support plate 207 away from the rotation point is facing upward; when the protective cover 201 is sleeved on the rear end of the shell body 1, the storage groove 206 is open and the end of the diagonal support plate 207 away from the rotation point is facing downward. At this time, the diagonal support plate 207 can be rotated out of the storage groove 206, so that the diagonal support plate 207 and the work surface and the multimeter 1 are distributed in a triangle, thereby realizing the tilted placement of the multimeter 1.

[0048] Please refer to Figures 1 to 6 The protective cover 201, the notch groove 202, the fixing plate 203, and the receiving groove 206 are integrally formed by an injection molding process, the raised edge 102 and the shell body 101 shell are integrally formed by an injection molding process, and the rotating connecting block 204 and the T-shaped column 205 are integrally formed by an injection molding process.

[0049] In this embodiment: It should be additionally explained that: the fixed plate 203 is formed with a hole for the T-shaped column 205 to pass through, and the fixed plate 203 and the T-shaped column 205 have a certain deformation reset elasticity, which can enable the large-diameter end of the T-shaped column 205 to pass through the hole and achieve a limited rotation connection with the hole. Through the above structure, the protective component 2 can be conveniently assembled, which is convenient for promotion and production.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
