[0021] As Figures 1-5 shown, the present utility model discloses a portable power quality device with a quick - detachable display module, including a mainframe, a mainframe housing 1, an upper cover 2, and a display module 4. The mainframe is installed inside the mainframe housing 1. The display module 4 is installed on the front of the mainframe housing 1. The display module 4 and the mainframe housing 1 are detachably installed. The upper cover 2 is detachably installed at the end of the mainframe housing 1. After removing the upper cover 2 from the mainframe housing 1, the display module 4 can be pulled out from the mainframe housing 1, and thus the display module 4 can be quickly taken out.

[0022] Chutes 6 are arranged along the vertical direction at the top edges of the front and back of the mainframe housing 1. Linear guide rails 10 are arranged along the vertical direction on the front and back sides inside the upper cover 2. The linear guide rail 10 on the front side inside the upper cover 2 corresponds to the chute 6 on the front of the mainframe housing 1, and the linear guide rail 10 on the front side inside the upper cover 2 can slide up and down in the corresponding chute 6 on the front of the mainframe housing 1. The linear guide rail 10 on the back side inside the upper cover 2 corresponds to the chute 6 on the back of the mainframe housing 1, and the linear guide rail 10 on the back side inside the upper cover 2 can slide up and down in the corresponding chute 6 on the back of the mainframe housing 1. The upper cover 2 is installed and detached from the mainframe housing 1 by sliding up and down the linear guide rail in the chute 6. Align the linear guide rail 10 on the upper cover 2 with the corresponding chute 6 and slide it downwards, then the upper cover 2 is installed on the mainframe housing 1. Slide the upper cover 2 upwards, and the upper cover 2 is detached from the mainframe housing 1.

[0023] The number of the chutes 6 and the linear guide rails 10 can be one or more. In this embodiment, two chutes 6 are arranged on the front and back of the mainframe housing 1 respectively, and two corresponding linear guide rails 10 are arranged on the front and back sides inside the upper cover 2 respectively.

[0024] The chute 6 provides a guide and an installation track for the installation and disassembly of the upper cover 2; the upper cover 2 is designed with four linear guide rails 10 corresponding to the four chutes 6 of the mainframe housing 1, and the linear guide rails 10 make the assembly and disassembly of the upper cover 2 more convenient.

[0025] In order to prevent the complete separation between the upper cover 2 and the mainframe housing 1, a limiting mechanism is provided between the upper cover 2 and the mainframe housing 1. The limiting mechanism is used to stop the upper cover 2 and the mainframe housing 1 when they are disassembled to a certain position, so that the upper cover 2 and the mainframe housing 1 are not completely separated.

[0026] The limiting mechanism in this embodiment is a stop buckle. A first stop buckle 11 is provided on the mainframe housing 1, and a second stop buckle 12 is provided inside the upper cover 2. When the upper cover 2 is disassembled from the mainframe housing 1, after the linear guide rail 10 of the upper cover 2 retreats a certain distance in the chute 6 of the mainframe housing 1, the second stop buckle 12 is blocked by the first stop buckle 11, and the upper cover 2 cannot continue to withdraw from the mainframe housing 1, so that the upper cover 2 is not completely separated from the mainframe housing 1, maintaining the integrity of the device mechanism. A first stop buckle 12 is provided at each of the inner edges on the left and right sides of the upper cover 2, and a first stop buckle 11 corresponding to the position of the second stop buckle 12 and capable of blocking the second stop buckle 12 is provided at the top of the left side and the top of the right side of the mainframe housing 1 respectively.

[0027] A convex block is provided at the outer bottom edge of the bottom surface of the upper cover 2 facing the front of the mainframe housing 1, and this convex block is the upper brim 7. A lower brim 8 is provided on the lower end surface of the front of the mainframe housing 1 facing the upper cover 2. The display module 4 is clamped between the upper brim 7 and the lower brim 8. The bottom of the display module 4 is placed inside the lower brim 8, and the top of the display module 4 is placed inside the upper brim 7. The upper brim 7 and the lower brim 8 jointly limit and fix the display module 4.

[0028] The portable power quality device further includes screws 3. By tightening or loosening the screws 3, the upper cover 2 and the mainframe housing 1 can be fixed or loosened, achieving the purpose of integrating or separating the mainframe housing 1 and the display module 4.

[0029] Threaded holes 9 are provided on the mainframe housing 1, and screws 3 are installed on the upper cover 2. The upper cover 2 and the screws 3 are in an anti-detachment fit. When the screws 3 are tightened, the screws 3 will extend into the threaded holes 9 to fix the upper cover 2 and the mainframe housing 1 as a whole. When the screws 3 are turned in the opposite direction, the screws 3 are screwed out of the threaded holes 9 in the opposite direction, pulling the upper cover 2. The linear guide rails 10 on the upper cover 2 slide backward along the corresponding chutes 6 of the mainframe housing 1, and at this time, the upper cover 2 and the mainframe housing 1 can be separated. The screws 3 are anti-detachment screws.

[0030] The number of screws 3 is two, and two threaded holes 9 are symmetrically provided at the top of the mainframe housing 1.

[0031] The portable power quality device further includes a plurality of buffer sheets 5, which are respectively installed on the mating surfaces of the mainframe housing 1 and the display module 4, and the upper cover 2 and the display module 4. The buffer sheets 5 are used to limit and protect the display module 4 in all directions.

[0032] The buffer sheet 5 is made of EVA material.

[0033] The beneficial effects of the present utility model are as follows: 1. For the portable power quality device of the present utility model, the display module 4 can be quickly and easily disassembled from the mainframe housing 1 and separated from the mainframe; 2. The display module 4 of the portable power quality device of the present utility model can be operated separately in hand or assembled with the mainframe for operation, which is flexible and convenient; 3. The mainframe and the display module 4 of the portable power quality device of the present utility model are assembled together, with a large display window and a front display, making it more intuitive to view and read data, and more convenient for monitoring and operation. While ensuring the realization of functions, it is more in line with the on-site use situation; 4. The portable power quality device of the present utility model is provided with a limiting mechanism, so that the upper cover 2 and the mainframe housing 1 will not be completely separated, and the upper cover 2 is not easily lost.

[0034] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
