Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, and in particular to an electric meter box which is easy to transport. Background Art

[0002] The electric meter box is a common device in the civil power grid. The electric energy meter and other supporting electrical components are installed in the electric meter box. The electric energy meter can measure the consumption of electric energy and is an essential device for calculating electricity bills and monitoring power consumption. At present, the electric meter box, the electric energy meter and other supporting electrical components need to be packaged separately for transportation. As shown in the Chinese utility model with patent number CN202222497167.6 (authorization announcement number CN218546807U), the device includes a box body, a harmonic electric energy meter and an electric energy meter. The harmonic electric energy meter and the electric energy meter are both arranged in the box body. The box body is provided with a box cover by hinges. The box body and the box cover form a suitcase. The front of the box body is also provided with a handle and a clamp ring. Therefore, the box body can be closed by the box cover to form a suitcase, and the electric energy meter is installed in the box body for easy carrying and transportation.

[0003] Although the aforementioned suitcase can be used to transport the energy meter, the energy meter and other supporting electrical components still need to be transported separately from the meter box, which increases transportation costs. Furthermore, it is necessary to design and manufacture a specific method for fixing the energy meter and other electrical components to prevent the energy meter and electrical components from shaking and being damaged during transportation. As a result, the transportation of the existing energy meter, other supporting energy meter items, and the meter box is relatively inconvenient, and the transportation and packaging costs are high. Therefore, further improvements are needed to the meter box. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an electric meter box with a reasonable structure and convenient transportation in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the electric meter box that is easy to transport includes a box body, which is characterized in that: a first limit plate extending in the left and right directions is provided in the box body, and the first limit plate divides the space in the box body into a first space located at the upper part and a second space located at the lower part. An electric energy meter is installed in the first space, and a second limit plate extending in the up and down directions is provided in the middle of the second space. A third L-shaped limit plate is also provided on the left and right sides of the second space. The first limit plate, the second limit plate and the third limit plate form an installation area for placing power supply components. A mounting seat for installing a circuit breaker is also provided in the second space. The circuit breaker can be installed on the mounting seat and abut against the second limit plate to be fixed in the second space.

[0006] Preferably, a support member is further provided within the installation area of ​​the second space, and the third limiting plate is divided into a first connecting section and a second connecting section arranged perpendicular to each other. The first connecting section is used to support the bottom of the electrical component, and the second connecting section is used to abut the side wall of the electrical component. The height of the support member is flush with the height of the first connecting section, and the electrical component is placed on the first connecting section and the support member. The third limiting plate can both abut the side wall of the electrical component and support the bottom of the electrical component. The cooperation between the support member and the first connecting section of the third limiting plate ensures a more stable placement of the electrical component.

[0007] Furthermore, there are at least two second limit plates, and the mounting seat is installed between the upper and lower second limit plates in the left-right direction. The upper and lower ends of the mounting seat are each provided with an inverted L-shaped extension edge, and the extension edge forms a slide groove extending in the left-right direction, and the slide groove forms a sliding fit with the connection block on the back of the circuit breaker. Part of the mounting seat is located in the installation area for placing electrical components, and the rest of the mounting seat is located in the placement area for installing the circuit breaker. This allows the extension edge of the mounting seat to cooperate with the circuit breaker to form a slide groove to limit the upward and downward movement of the circuit breaker, and also to support the electrical components, thereby increasing the utilization rate of the mounting seat. In addition, the slide groove of the mounting seat slides with the connection block of the circuit breaker, allowing the circuit breaker to be adjusted accordingly in the left-right direction according to user needs.

[0008] Furthermore, the third limiting plate is divided into a first connecting section and a second connecting section, which are arranged perpendicular to each other. The first connecting section is used to support the bottom of the electrical component, and the second connecting section is used to abut the side wall of the electrical component. The height of the extended edge is flush with the height of the first connecting section, and the electrical component is placed on the first connecting section and the extended edge. The extended edge and the first connecting section of the third limiting plate jointly support the left and right sides of the electrical component, ensuring more stable placement of the electrical component.

[0009] Furthermore, two fourth limiting plates are provided within the second space. The two fourth limiting plates are disposed on one side of the second limiting plate and are respectively disposed at the upper and lower ends of the mounting base. The fourth limiting plates and the second limiting plate form a placement area for mounting the circuit breaker. The fourth limiting plates and the second limiting plate can restrict left and right movement of the circuit breaker.

[0010] Furthermore, the back of the energy meter is provided with a mounting hole for hanging or positioning, and a first support block corresponding to the mounting hole and protruding forward is provided in the first space, and a step extending forward is provided on the first support block. A screw that can be inserted into and fixed in the mounting hole is installed on the first support block, and the head of the screw can abut against the step. The upper end of the energy meter is often fixed in the box by the cooperation of the screw and the mounting hole. In the past, in order to prevent the excessive rotation of the screw from affecting the fixing effect, a certain protrusion is usually provided in the screw hole for screw installation to ensure that the screw is installed in place. The present application replaces the protrusion with a step located on one side of the screw hole. The step abuts against the head of the screw to ensure that the screw is installed in place. The step is more convenient for processing, and the operator can more intuitively observe the position of the screw installation.

[0011] Furthermore, at least two forward-projecting second support blocks are provided within the first space. The second support blocks are positioned below the first support blocks and are flush with the first support blocks. The energy meter can also be secured to the second support blocks with screws, allowing the energy meter to be secured within the first space of the box at three points.

[0012] Furthermore, the box body is provided with at least four connectors integrally formed with the box body, and the connectors are respectively arranged at the upper left, upper right, lower left and lower right of the box body. A circular groove that is concave backward is provided in the center of the connector, and reinforcing ribs are provided at intervals along the circumference of the groove on the connector. The reinforcing ribs extend radially, and the reinforcing ribs can support the portion of the connector other than the groove. The groove can be destroyed under the action of external force to form a fixing hole for fixing the box body. After the electric meter box is transported to the destination, the operator can use a tool to act on the groove of the connector, so that the groove is destroyed by external force to form a fixing hole, thereby fixing the box body of the electric meter box to the corresponding wall; and the reinforcing ribs can prevent the portion of the connector other than the groove from being damaged, thereby ensuring the use effect of the connector. In addition, the groove of the connector can prevent dust and impurities from entering the electric meter box during transportation, and the fixing hole can be opened during installation.

[0013] Furthermore, the groove is set in a waist shape. When the groove is damaged by external force, a waist-shaped hole is generated, and the waist-shaped hole can provide a certain adjustment space for the box body of the meter box when it is installed.

[0014] Furthermore, the back of the box is provided with at least two spaced-apart, forward-projecting grooves. The grooves extend left and right, with their left and right ends communicating with the outside. The grooves are also provided with baffles integrally formed with the box, with the outer surface of the baffles flush with the back of the box. The meter box can also be secured to a utility pole by passing two steel cables through the grooves.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) The body of the electric meter box is divided into a first space and a second space. During transportation, the electric energy meter can be directly installed in the first space, and the circuit breaker and other electrical components can also be directly placed or installed in the second space and transported together with the electric meter box, saving the packaging and transportation costs of the electric energy meter, the electric meter box and the electrical components. After the electric meter box is transported to the destination, the electrical components can be taken out and then installed accordingly;

[0017] (2) The first limit plate originally only restricts the electric energy meter from moving downward into the second space, thereby fixing the position of the electric energy meter in the electric energy meter box; however, the present application utilizes the first limit plate to simultaneously restrict the electrical components from moving upward into the first space, thereby making the first limit plate more functional and having a higher utilization rate;

[0018] (3) The second limit plate originally only limits the left and right movement of the circuit breaker, so that the position of the circuit breaker in the meter box is fixed; however, the present application uses the second limit plate and the third limit plate to simultaneously limit the left and right movement of the electrical components, thereby ensuring the stability of the electrical components during transportation. The utilization rate of the second limit plate is higher, making the box structure of the meter box reasonable while having multiple functions, thereby reducing the production cost of the manufacturer.
