Description

Technical Field

[0001] The invention relates to the technical field of electric meter box equipment, and in particular to an indoor electric meter box body and an electric meter box assembly. Background Art

[0002] An electric meter box is a box used to install an electric energy meter and related electrical equipment to measure and record electricity usage. It is usually installed at the entrance of the power supply to a residential, commercial building or industrial site to monitor and meter electric energy consumption.

[0003] At present, when we need to shut down the power supply to replace the traditional meter box, we need to declare the power outage plan in advance. After approval, we need to post the power outage notice in the community or village before the power outage. When the maintenance personnel arrive at the site, they must first remove the incoming and outgoing wires of the meter box, unscrew the expansion screws that fix the meter box, remove the old meter box assembly, install the new meter box, install the energy meter, tighten the screws, and then connect the incoming and outgoing wires.

[0004] In the actual process of replacing the damaged meter box, it is impossible to replace it in the original position due to various complex reasons on site. First, it is necessary to re-drill holes for fixing (usually installed on the customer's wall), but customers often disagree, which easily leads to customer disputes; secondly, if the position is changed, the original wire length is not suitable. If the wire is short, a joint will be formed, increasing the hidden danger point; thirdly, the replacement of the meter box assembly takes a long time, the replacement efficiency is low, the replacement cost is high, and the replacement process is cumbersome. According to on-site statistics, the damage of the meter box assembly is often caused by the damage of the meter box body (upper cover or side panel), and the internal circuit breaker, wires and connectors can continue to be used. Due to the design of traditional products, the overall replacement is required, resulting in a waste of manpower and financial resources. Summary of the invention

DETAILED DESCRIPTION

[0043] 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 described embodiments are 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 creative work are within the scope of protection of the present invention.

[0044] Before further describing the embodiments of the present invention in detail, the directional terms involved in the embodiments of the present invention, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the protection scope of the present invention.

[0045] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] Figure 1 FIG. 1 is an external schematic diagram of an electric meter box according to an embodiment of the present invention.

[0048] like Figure 1 As shown, one embodiment of the present invention provides an electric meter box 100 for indoor use, and the electric meter box 100 includes:

[0049] A fixed bottom plate 110 is fixedly connected to the wall;

[0050] The enclosure 120 is disposed on a side of the fixed bottom plate 110 away from the wall. The enclosure 120 is detachably connected to the fixed bottom plate 110 via a hinge 140. The enclosure 120 and the fixed bottom plate 110 form a receiving chamber, and the receiving chamber is used to receive electrical components.

[0051] The cover plate 130 is disposed on a side of the enclosure 120 away from the fixed bottom plate 110 . The cover plate 130 is used to close the accommodating chamber. The cover plate 130 is detachably connected to the enclosure 120 .

[0052] Among them, the meter box 100 used indoors includes a fixed bottom plate 110, a surrounding plate 120 and a cover plate 130, which respectively form three module parts and can be disassembled and repaired separately. The surrounding plate 120 is connected to the fixed bottom plate 110 by a hinge 140. When the meter box 100 is damaged, each part of the meter box 100 can be replaced separately, which improves the replacement efficiency and reduces the difficulty of disassembly. At the same time, on-site replacement does not require extra space, and even if there are obstacles around the meter box 100, it will not affect the on-site replacement operation.

[0053] Specifically, the fixed base plate 110 is directly fixedly connected to the wall, and then the enclosure 120 is detachably connected to the fixed base plate 110 through the hinge 140. The fixed base plate 110 and the enclosure 120 form a accommodating chamber for accommodating electrical components, and the cover 130 is used to close the accommodating chamber. That is, the entire existing meter box 100 is modularized, and the fixed base plate 110, the enclosure 120 and the cover 130 are respectively designed as separate components. The damaged parts in the meter box can be replaced without removing the fixed base plate 110. The replacement process is simple and the replacement efficiency is high, thereby reducing the work intensity of the staff. At the same time, any component can be replaced separately without overall replacement. The replacement cost is low, thereby improving customer experience.

[0054] Figure 4 FIG. 4 is a rear view of a fixed base plate according to an embodiment of the present invention.

[0055] It should be noted that if Figure 4 As shown, a heat dissipation hole 114 and a support block 115 are provided on the fixed base plate 110. The setting of the support block 115 allows a certain space to be left between the fixed base plate 110 and the front, which is convenient for heat dissipation of the heat dissipation hole 114 and prevents the heat dissipation hole 114 from being blocked by the wall, thereby affecting the heat dissipation of the meter box 100 and further affecting the service life of the meter box 100.

[0056] Figure 2 is a schematic diagram of the interior of an electric meter box according to an embodiment of the present invention;

[0057] In a possible implementation, Figure 2As shown, the enclosure 120 includes a pair of side guard plates 121 arranged in parallel, an upper clamping plate 122 and a lower clamping plate 123 for connecting the pair of side guard plates 121, and a connecting plate 124, the connecting plate 124 is connected to the pair of side guard plates 121 and the upper clamping plate 122, the connecting plate 124 is vertically arranged to the upper clamping plate 122, the connecting plate 124 faces the accommodating chamber, a plurality of notches 125 are provided on the connecting plate 124, mounting support plates 129 are provided at both ends of the notches 125, a connecting rod 126 is fixed on the mounting cardboard, the connecting rod 126 is arranged parallel to the notch 125, a hinge 140 is provided on the fixed base plate 110, one end of the hinge 140 is hinged to the fixed base plate 110, and the other end of the hinge 140 is provided with a connecting groove, and the connecting groove is engaged and connected with the connecting rod 126.

[0058] The enclosure 120 further includes a connecting plate 124, which is U-shaped. The connecting plate 124 is respectively connected to a pair of side guard plates 121 and an upper clamping plate 122, and is vertically arranged with a pair of side guard plates 121 to extend into the accommodating space. A plurality of notches 125 are provided on the connecting plate 124, and a pair of mounting support plates 129 are provided on the notches 125. A connecting rod 126 is fixed to the pair of mounting support plates 129. A hinge 140 is hinged on the fixed base plate 110, and a connecting groove is provided on one end of the hinge 140 away from the hinge point, and the connecting groove can be connected to the connecting rod 126. That is to say, when it is necessary to remove the enclosure 120 from the fixed base plate 110, the hinge 140 is separated from the connecting rod 126 through the position of the notch 125, that is, the hinge 140 is opened upwards, so that the hinge 140 is separated from the enclosure 120, and the fixed floor and the enclosure 120 can be disassembled and replaced. Then, after the new enclosure 120 is buckled on the fixed base plate 110, the hinge 140 is pressed downward to re-engage the connecting groove on the hinge 140 with the connecting rod 126 to achieve the connection between the fixed base plate 110 and the enclosure 120. The installation is convenient and the workload of the staff is reduced.

[0059] Furthermore, at least one hinge 140 is usually provided on each of the three sides of the U-shaped connecting plate 124. According to the installation space requirements of the electrical components, the present embodiment provides two connecting rods 126 on each side of the connecting plate 124, that is, each side is connected to the fixed base plate 110 through two hinges 140. Usually, the two hinges 140 on each side are provided near the two ends of each side. That is to say, the present embodiment adopts six hinges 140 to achieve the detachable connection between the fixed base plate 110 and the enclosure 120, thereby improving the connection stability and reliability between the fixed base plate 110 and the enclosure 120.

[0060] It should be noted that the height of the enclosure 120 is determined according to the electrical components contained in the meter box 100, so that the distance between the fixed bottom plate 110 and the cover plate 130 is greater than the thickness of the electrical components, ensuring a certain amount of air circulation space for easier heat dissipation. A pair of side protection plates 121, an upper clamping plate 122, and a lower clamping plate 123 are provided with multiple rows of heat dissipation holes 127 on at least one side to improve the heat dissipation function of the meter box 100.

[0061] Figure 3 for Figure 2 An enlarged schematic diagram of point A.

[0062] In a possible implementation, Figure 3 As shown, the hinge 140 includes:

[0063] The hinged support 141 is fixedly disposed on the fixed base plate 110;

[0064] The hinge plate 142 is hinged at one end to the hinge support 141, and a connecting groove is provided on the other end of the hinge plate, the connecting groove is arranged toward the fixed bottom plate 110, the connecting groove is engaged with the connecting rod 126, and a limiting groove is provided on the hinge plate 142;

[0065] The limit stopper 143 is fixedly connected to the fixed bottom plate 110 . The limit stopper 143 is disposed in the hinge support 141 . The limit stopper 143 matches the limit groove.

[0066] Among them, the hinge 140 includes a hinge support 141 and a hinge plate 142 hinged to the hinge support 141, and the other end of the hinge plate 142 is engaged with the connecting rod 126. The hinge 140 is opened by applying force upward through the slot 125 to separate the fixed base plate 110 from the enclosure 120. The hinge 140 is forced downward to connect the hinge 140 and the connecting rod 126 to connect the fixed base plate 110 with the enclosure 120. The disassembly and installation are simple and convenient. The hinge 140 does not need to be removed and can be directly placed on the fixed base plate 110, which is not easy to cause the loss of parts, thereby ensuring the reliability of the disassembly and assembly of the enclosure 120 and the fixed base plate 110.

[0067] It should be noted that a limit stopper 143 is also provided on the fixed base plate 110, and the limit stopper 143 corresponds to the position of the limit groove on the hinge plate 142, which can ensure that the position of the hinge plate 142 corresponds to the position of the connecting rod 126, thereby ensuring the reliability of the connection between the hinge 140 and the connecting rod 126.

[0068] In a possible implementation, Figure 2 As shown, the electric meter box 100 also includes:

[0069] The mounting back plate 150 is provided with an avoidance groove, which matches the position of the hinge 140 . The mounting back plate 150 is detachably connected to the fixed bottom plate 110 , and the mounting back plate 150 is used for fixing and mounting electrical components.

[0070] The fixed base plate 110 is fixed on the wall, the mounting back plate 150 is fixed on the fixed base plate 110 , and the electrical components are fixed on the mounting back plate 150 , which facilitates the replacement of the electrical components and improves the overall protection level of the meter box 100 .

[0071] It should be noted that an avoidance groove is provided on the installation back plate 150, and the position of the avoidance groove is adapted to the position of the hinge 140. The hinge support 141 of the hinge 140 has a certain thickness. Therefore, the setting of the hinge 140 and the avoidance groove can also have a certain limiting and positioning effect on the installation back plate 150, thereby improving the convenience of installation. At the same time, the installation back plate 150 and the fixed base plate 110 can be connected by fewer connecting parts (bolts), thereby improving the efficiency of disassembly and installation.

[0072] Furthermore, some small holes may be provided on the mounting back plate 150 , and the positions of the small holes correspond to the positions of the heat dissipation strip holes 114 on the fixed bottom plate 110 , so that the heat dissipation performance of the meter box 100 can be improved.

[0073] Figure 5 Schematic diagram of a cable hub according to an embodiment of the present invention.

[0074] In a possible implementation, Figure 5 As shown, a cable collection buckle 151 is provided on one end of the mounting back plate 150 close to the lower clamping plate 123, and the cable collection buckle 151 includes:

[0075] The lower buckle 1511 is fixedly connected to the mounting back plate 150, and a first mounting arc groove is provided at the center of the lower buckle 1511, and an elastic pad is provided in the first mounting arc groove;

[0076] The upper buckle 1512 is arranged corresponding to the lower buckle 1511. The upper buckle 1512 is provided with a second installation arc groove, and an elastic pad is arranged in the second installation arc groove. The first installation arc groove and the second installation arc groove form a wire collection groove;

[0077] The tension spring 1513 is disposed between the upper buckle 1512 and the lower buckle 1511 , and the tension spring 1513 is disposed away from the first installation slot and the second installation slot.

[0078] Among them, through the setting of the wire collection buckle 151, the various connecting wires of the components can be centrally organized, which effectively improves the efficiency of the staff in organizing the wires inside the meter box 100, thereby improving the efficiency of installing electrical components.

[0079] It should be noted that a wire collection groove, that is, a wire collection accommodating channel, is formed by the first mounting arc groove on the lower buckle 1511 and the second mounting arc groove on the upper buckle 1512, which facilitates the centralized placement of all electrical connection wires in the wire collection groove, improves the cleanliness inside the electric meter box 100, and can also improve the work efficiency during maintenance and replacement.

[0080] Furthermore, the upper buckle 1512 and the lower buckle 1511 are connected by a tension spring 1513, that is, one end of the tension spring 1513 is fixedly connected to the lower buckle 1511, and the other end of the tension spring 1513 is fixedly connected to the upper buckle 1512. Two tension springs 1513 are usually used to realize the connection between the upper buckle 1512 and the lower buckle 1511. The setting of the tension spring 1513 makes a compression effect between the upper buckle 1512 and the lower buckle 1511, so as to prevent the long electrical connection wires from accumulating at the bottom of the meter box 100 under the action of gravity, affecting the aesthetics. A plurality of wire collection buckles 151 can be provided as needed, which will not be described in detail here.

[0081] In a possible implementation, Figure 5 As shown, a transition plate 111 is provided on one side where the fixed base plate 110 is connected to the lower clamping plate 123. The transition plate 111 is connected to the fixed base plate 110 in an arc-shaped transition connection. The transition plate 111 is vertically arranged to the fixed base plate 110. The transition plate 111 faces one side of the lower clamping plate 123. A lower arc groove 1111 is provided on the transition plate 111. An upper arc groove is provided on the lower clamping plate 123. The lower arc groove 1111 and the upper arc groove are arranged correspondingly, and the transition plate 111 is located inside the enclosure 120.

[0082] Among them, through the arrangement of the lower arc groove 1111 on the transition plate 111 and the upper arc groove on the lower clamping plate 123, a through hole for the electrical connection line is formed, the connection between the inlet and outlet connection lines and the electrical components, and a position limiting function is provided for the inlet and outlet connection lines, which can avoid confusion of the inlet and outlet connection lines. In this embodiment, two lower arc grooves 1111 and two upper arc grooves are arranged to distinguish the inlet connection lines from the outlet connection lines, which improves the replacement and maintenance efficiency of the staff during replacement, and is more beautiful during use, thereby improving the user experience.

The movable lock tongue 1332 can rotate on the fixed lock tongue 1331 under the action of a key. The lock tongue mouth matches the fixed lock tongue 1331 and the movable lock tongue 1332. When the movable lock tongue 1332 and the fixed lock tongue 1331 are aligned, they are used to open the cover 130. When the movable lock tongue 1332 and the fixed lock tongue 1331 deviate, they are used to lock the cover 130 with the fixed base plate 110.

[0090] It should be noted that there is a movable shaft on the lock tongue 133, and a key hole 1333 is provided on the movable shaft. The key hole 1333 matches the groove of the key and can rotate in the fixed lock tongue 1331. The movable shaft is fixed to the movable lock tongue 1332, so the key drives the movable shaft and the movable lock tongue 1332 to rotate in turn, so that the lock tongue 133 and the connecting seat 113 can be connected to achieve a locked state, such as Figure 7 As shown, when it is necessary to open, the key drives the movable shaft and the movable lock tongue 1332 to rotate and overlap the fixed lock tongue 1331, as shown in FIG. Figure 6 As shown, the locking tongue 133 and the connecting seat 113 can be separated, that is, the cover plate 130 can be opened.

[0091] Furthermore, the cover 130 and the enclosure 120 need to be connected by some screws to prevent the lock tongue force from being too concentrated, causing the cover 130 to tilt up, affecting the sealing of the cover 130 to the accommodating chamber. The setting of the lock tongue 133 and the connecting seat 113 can prevent non-staff from opening the meter box 100 privately and tampering with the meter body 300, thereby improving the safety and anti-theft properties of the meter box 100.
