[0033] The data line 5 of the wired video camera meter reader 4 is passed through the first buckle 8, the second buckle 11 and the third buckle 12 in sequence, and then connected to the gateway 6. At the same time, the data line 5 can slide inside the first buckle 8 and the second buckle 11. At this time, the second buckle 11 is moved. When the second buckle 11 moves, the suspended data line 5 is straightened, so that the data line 5 forms a U shape between the first buckle 8, the second buckle 11 and the third buckle 12.

[0034] like Figure 1 and Figure 3As shown, one end surface of the box body 1 is symmetrically equipped with a box door 2 through a hinge, a positioning strip 7 is fixedly installed at the bottom end of the box body 1 and fits with the top end of the box door 2, and the positioning strip 7 is placed in pairs. The design of the box door 2 is convenient for opening and closing the box body 1, so as to facilitate the maintenance of the devices inside the box body 1. A glass 3 is fixedly installed inside the box door 2. The design of the glass 3 is convenient for observing the use of the electric meter inside the box body 1. A wired video camera meter reader 4 is bonded to one end of the glass 3. The wired video camera meter reader 4 is used to shoot and record the electric meter, which improves the convenience of data recording on the electric meter. A data line 5 is fixedly installed inside the wired video camera meter reader 4. The data line 5 is used for data transmission. A gateway 6 is installed at one end of the data line 5. The gateway 6 is used for data transmission. The data line 5 is connected to the inside of the buckle 1 8, the buckle 2 11 and the buckle 3 12. The shape formed by the buckle 1 8, the buckle 2 11 and the buckle 3 12 is a U-shape, which is used to place the data line 5. The buckle 2 A counterweight 10 is fixedly installed on the back of 11, and the counterweight 10 is used to drive the buckle 2 11 to move. An inclined groove 9 is opened at the middle of the positioning strip 7 corresponding to one end of the counterweight 10, and the inclined groove 9 is inclined downward along the horizontal plane. The inclined groove 9 is used to limit the counterweight 10, and under the factor of gravity, the counterweight 10 is inclined downward along the inclined groove 9. The buckle 1 8 and the buckle 3 12 are both provided with a matching groove. The shape of the buckle 3 12 is U-shaped, and the U-shaped buckle 3 12 is used for flipping the angle of the data cable 5, and the fitting groove opened inside the U-shaped buckle three 12 not only reduces the friction surface between the data cable 5 and the buckle three 12 but also reduces the use of materials. The buckle one 8 is clamped and installed with a card plate 21 at one end surface, and the two ends of the card plate 21 are respectively fitted with the inner walls of the fitting groove of the buckle one 8. The card plate 21 and the buckle one 8 are clamped and connected to complete the fixation of the data cable 5, and an arc groove is opened on one end surface of the card plate 21, and the arc groove is used for fitting with the data cable 5.

[0035] When the box door 2 is opened or closed, the wired video camera meter reader 4 is driven to move.

Due to the action of the card plate 21, the data line 5 and the buckle 1 8 are prevented from being separated, and the top of the data line 5 is fixed by the action of the buckle 3 12. When the data line 5 moves, the data line 5 between the buckle 1 8 and the wired video camera meter reader 4 is extended, and because the top of the data line 5 is fixed, the buckle 2 11 receives tension. The buckle 2 11 is U-shaped, so that the data line is deflected at an angle inside the buckle 2 11, and a pair of sliding grooves larger than the diameter of the data line 5 are provided inside the buckle 2 11, so that the data line 5 can be displaced inside the buckle 2 11, and the buckle 11 moves inside the inclined groove 9 through the counterweight 10, so that When the buckle 2 11 is subjected to tension, the buckle 2 11 is driven to move under the action of the tension, and the buckle 2 11 drives the counterweight 10 to move along the inside of the inclined groove 9 when it moves. When the box door 2 is closed, the counterweight 10 drives the buckle 2 11 to move due to the action of gravity, and the buckle 2 11 drives the data cable 5 to move when it moves. When the data cable 5 moves, it moves along the inside of the buckle 1 8. At this time, the distance between the bottom end of the buckle 1 8 and the wired video camera meter reader 4 becomes shorter, which changes the phenomenon that the data cable 5 needs to be arranged by personnel in the prior art. This method automatically stores the data cable 5, reduces the process required for personnel to store it, and the data cable 5 is placed in a row, which is not only more beautiful, but also prevents the suspended data cable 5 from interfering with one end of the glass 3, thereby affecting the purpose of personnel observing the devices inside the box 1 through the glass 3.

[0036] like Figure 2 and Figure 4As shown, a placement plate 16 is installed on the top of the gateway 6, and the two ends of the data line 5 are fixed on the gateway 6 and the wired video camera meter reader 4 in sequence, which are used for information transmission between the gateway 6 and the wired video camera meter reader 4.

The two ends of the placement plate 16 are symmetrically fixed with a barrier strip 18. The card strip 17 and the barrier strip 18 are curved surface structures with elastic functions. A weakening groove 19 is provided at the bottom end of the inner wall of the barrier strip 18. When the gateway 6 is fixed to the case, the card strip 17 can clamp and fix the four corners of the gateway 6, and the barrier strip 18 can clamp and fix the two ends of the gateway 6. Since the barrier strip 18 and the card strip 17 are elastic clamping structures, when the gateway 6 is clamped The operation is simple and efficient during the fixing process. A guide groove 20 is provided inside the barrier strip 18 near the top of the box body 1. The position of the guide groove 20 weakens the top of the barrier strip 18, thereby facilitating the bending of the edge of the barrier strip 18. Vertical drainage holes and horizontal guide grooves are provided inside the placement plate 16 for the flow of gas. The barrier strip 18 and the card strip 17 provided solve the problem of direct placement in the prior art that easily causes displacement of the gateway 6, and solves the method of fixing with screws in the prior art. This method is convenient for the installation of the gateway 6 and is not easy to cause the displacement of the network management. It further prevents the displacement of the gateway 6 and causes the data cable 5 to move along the outside of the box door 2, thereby indirectly improving the aesthetics of the overall placement of the data cable 5.

[0037] A cylinder 15 is symmetrically embedded and installed on the top of the placement plate 16, and a blocking and drainage plate 14 is clamped and installed on the top of the cylinder 15. The blocking and drainage plate 14 is used to drain the gas and can block rainwater. A plug-in column 13 is symmetrically fixedly installed on the bottom of the blocking and drainage plate 14.

The inclination angle is used for cooperation with the plug-in column 13 and can achieve a limiting effect on the plug-in column 13. Chamfers are symmetrically provided on the top and bottom edges of the blocking and drainage plate 14. The cross-sectional surface of the blocking and drainage plate 14 is ◇-shaped, which is convenient for blocking rainwater and draining gas.

[0038] The working principle of the utility model is that when the gateway 6 needs to be installed, the operator installs the gateway 6 at the bottom of the placement plate 16 along the card strip 17 and the barrier strip 18, and then inserts the plug-in column 13 into the card hole of the box body 1 to complete the installation of the gateway 6, and then connects the data line 5 of the wired video camera meter reader 4 to the gateway 6, and then snaps the data line 5 into the inside of the buckle 1 8, the buckle 2 11 and the buckle 3 12 in turn, and then adheres the wired video camera meter reader 4 to the glass 3, and at this time the wired video camera meter reader 4 corresponds to the electric meter.
