[0026] The following will cooperate with the drawings and embodiments to elaborate in detail on the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0027] As Figures 1-6 shown, the electric meter housing facilitating quick disassembly and assembly provided in this embodiment includes:

[0028] The electric meter housing 1, the electric meter housing 1 includes a lower shell 2 and an upper shell 3 clamped on the lower shell 2. The electric meter housing 1 is used to support, fix and protect the internal components installed in the electric meter housing 1. The lower shell 2 and the upper shell 3 are assembled with each other to facilitate the formation of the electric meter housing 1;

[0029] The insertion card embedding installation and fixing component 4 is arranged between the lower shell 2 and the upper shell 3. The insertion card embedding installation and fixing component 4 is used to quickly install or quickly disassemble the lower shell 2 and the upper shell 3, and at the same time, no auxiliary tool is required, so that the operator can quickly disassemble and assemble the electric meter housing without tools, thereby greatly reducing the operation burden of the operator during disassembly and assembly.

[0030] Further, asFigure 4 As shown, the card-inserting and embedding installation and fixing component 4 includes two elastic buckles 5 and rigid buckles 6 below the two elastic buckles 5. The two elastic buckles 5 are symmetrically arranged near the upper end corners between the lower shell 2 and the upper shell 3, and the two rigid buckles 6 are symmetrically arranged near the lower end corners between the lower shell 2 and the upper shell 3. The two elastic buckles 5 facilitate fixing and buckling the upper end corners of the lower shell 2 and the upper shell 3 together, and the two rigid buckles 6 facilitate fixing and buckling the lower end corners of the lower shell 2 and the upper shell 3 together.

[0031] Further, as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the elastic buckle 5 includes a first connecting block 7 arranged on the inner wall of the lower shell 2, a second connecting block 8 arranged on the inner wall of the upper shell 3, and a double-headed elastic card 9 inserted between the first connecting block 7 and the second connecting block 8. The first connecting block 7 facilitates clamping and fixing the lower shell 2 on the double-headed elastic card 9, the second connecting block 8 facilitates clamping and fixing the shell 3 on the double-headed elastic card 9, and the double-headed elastic card 9 facilitates fixing and clamping the first connecting block 7 and the second connecting block 8 together.

[0032] Further, as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the double-headed elastic card 9 includes two convex card feet 10, a pressure spring 11 arranged between the two ends of the two convex card feet 10, and a connecting ring 12 arranged between the middle parts of the two convex card feet 10. Clamping and installation grooves 13 adapted to the two ends of the double-headed elastic card 9 are provided on both the first connecting block 7 and the second connecting block 8. The clamping and installation grooves 13 facilitate clamping and fixing one end of the double-headed elastic card 9 in the first connecting block 7 and the other end of the double-headed elastic card 9 in the second connecting block 8, so that the double-headed elastic card 9 can fix and clamp the first connecting block 7 and the second connecting block 8 together. The connecting ring 12 facilitates connecting the two convex card feet 10 together, so that there is a certain rigid resilience between the middle parts of the two convex card feet 10. The pressure spring 11 facilitates increasing the resilience at the two ends of the two convex card feet 10. The two convex card feet 10 facilitate making the double-headed elastic card 9 better fit the inner wall of the clamping and installation groove 13.

[0033] Further, as Figure 2 , Figure 5 and Figure 6As shown, the hard buckle 6 includes a fixed hook 14 symmetrically arranged on the inner wall of the upper shell 3 and a fixed hook block 15 symmetrically arranged on the inner wall of the lower shell 2. The fixed hook block 15 is embedded in the recess of the fixed hook 14. The fixed hook 14 and the fixed hook block 15 cooperate with each other so that the lower end corner of the upper shell 3 can be more firmly embedded in the lower end corner of the lower shell 2, so that the hard buckle 6 can also increase the overall connection strength between the upper shell 3 and the lower shell 2.

[0034] Further, if Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, a wiring fixing block 16 is provided at the rear end of the lower shell 2, a transparent screen protection shell 17 is provided on the upper surface of the upper shell 3, and a wiring cover 18 is hinged at the rear end of the upper shell 3. The wiring fixing block 16 is convenient for fixing the wiring terminals connected to the device, and the transparent screen protection shell 17 is convenient for protecting the display screen arranged inside the device. The wiring cover 18 can be flipped open to facilitate the connection of the wiring terminals to the wiring fixing block 16.

[0035] Further, if Figure 1 and Figure 6 As shown, the wiring cover 18 is snap-fitted onto the wiring fixing block 16 through limiting protrusions 19 symmetrically arranged on the upper shell 3. The limiting protrusions 19 facilitate fixing the wiring cover 18 to prevent the wiring cover 18 from opening by itself, ensuring that the wiring cover 18 will only be opened when manually pushed.

[0036] Further, if Figure 1 , Figure 2 as well as Figure 6 As shown, the inner wall of the wiring cover 18 is engraved with several common wiring diagrams 20, and the upper shell 3 is provided with a control contact button key 21. The several common wiring diagrams 20 are convenient for providing wiring guidance to the operating personnel, and the control contact button key 21 is convenient for connecting some necessary switch buttons on the control circuit board to the housing of the device.

[0037] like Figures 1-6As shown in the figure, the principle of the meter housing that is convenient for quick disassembly and assembly provided in this embodiment is as follows: When using this device, two double-headed elastic cards 9 should be taken out first. At this time, it should be checked whether the four pressure springs 11 in the two double-headed elastic cards 9 are intact and have good resilience. Then, the two double-headed elastic cards 9 can be inserted and installed in the two first connection blocks 7 in the lower housing 2 in sequence. At this time, one end of the double-headed elastic card 9 is inserted into the card-inserting and installing groove 13 on the first connection block 7. Under the action of the pressure spring 11, the convex card feet 10 that enter the card-inserting and installing groove 13 will tightly fit on the inner wall of the card-inserting and installing groove 13 in the first connection block 7. At this time, the convex points on the convex card feet 10 will be engaged with the inner wall of the card-inserting and installing groove 13 in the first connection block 7, so that one end of the double-headed elastic card 9 is tightly fitted and embedded in the first connection block 7 and will not loosen without manual intervention. Then, some internal working components can be installed in the lower housing 2;

[0038] After the internal working components are installed, the upper housing 3 should be taken out first. Then, the two fixed hooks 14 at the lower end corners of the upper housing 3 are tilted and hooked on the two fixed hook blocks 15 at the lower end corners of the lower housing 2. Subsequently, the upper end corners of the upper housing 3 are pressed downward against the upper end corners of the lower housing 2. At this time, the two second connection blocks 8 at the upper end corners of the upper housing 3 will approach, fit, and finally be embedded in the convex card feet 10 exposed by the two double-headed elastic cards 9. At this time, due to the action of the pressure spring 11, the slight inclination of the upper housing 3 caused by the installation of the rigid buckle 6 first will not affect the installation of the upper housing 3. Then, under the action of the pressure spring 11, the convex card feet 10 will tightly fit on the inner wall of the card-inserting and installing groove 13 in the second connection block 8. At this time, the convex points on the convex card feet 10 will be engaged with the inner wall of the card-inserting and installing groove 13 in the second connection block 8, so that the other end of the double-headed elastic card 9 is tightly fitted and embedded in the second connection block 8 and will not loosen without manual intervention. In this way, the upper housing 3 can be quickly snap-fitted and installed on the lower housing 2;

[0039] When the upper housing 3 needs to be removed from the lower housing 2, the operator needs to hold one hand at the upper end corner of the upper housing 3 and the other hand at the upper end corner of the lower housing 2, and then pull forcefully to make one end of the double-headed elastic card 9 disengage from the first connection block 7, or the other end of the double-headed elastic card 9 disengage from the second connection block 8. This makes the upper end corner of the upper housing 3 disengage from the upper end corner of the lower housing 2. Then, the upper housing 3 is tilted upward and taken, which makes the two fixed hooks 14 at the lower end corners of the upper housing 3 disengage from the two fixed hook blocks 15 at the lower end corners of the lower housing 2, so that the upper housing 3 can be removed from the lower housing 2. Before the next installation, it should be checked whether the removed double-headed elastic card 9 is damaged. If it does not affect the use, it can be used continuously. If it affects the use, a new double-headed elastic card 9 needs to be replaced.

[0040] The above description shows and describes several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in the relevant field. And any changes and alterations made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
