Technical Field

[0001] The utility model belongs to the field of electric meter boxes, and particularly relates to an electric meter box with a tool-free disassembly and assembly structure for electric meters. Background Art

[0002] An electric meter box is a device used to install electric energy meters and other electrical instruments, usually installed in residential buildings, commercial buildings, and industrial facilities. It is one of the key devices for electric power metering. Its main function is to monitor and manage electric power consumption in real time. By installing an electric meter box and an electric power meter, the electricity consumption of a building or facility can be monitored in real time, and the changes and trends of electric power consumption can be understood through the electric meter data.

[0003] Traditional electric meters and components are mostly fixed inside the electric meter box by means of screws, etc. During long-term use, regular maintenance or replacement is required. Usually, tools are needed to disassemble and assemble the electric meters and components inside. Maintenance personnel need to spend more time preparing and using tools, forming a dependence on tools. Although the electric meters and components can be taken out of the electric meter box with the cooperation of tools, in case of emergency, there may be problems such as inconvenience for maintenance personnel to carry or omission of tools, which prolongs the repair time and affects the continuity of power services. Therefore, a new structure is needed to solve the above-mentioned problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an electric meter box with a tool-free disassembly and assembly structure for electric meters to solve the problems raised in the above background art.

[0005] The utility model is realized through the following technical solutions: An electric meter box with a tool-free disassembly and assembly structure for electric meters includes: a box body, a railing, and a quick-release component. A device cavity is formed by the front surface of the box body recessing backward. A positioning boss is installed inside the device cavity, and a positioning plate located in front of the positioning boss is fixed at the rear side inside the device cavity;

[0006] The railing is attached to the surface of the positioning plate. Concave holes are formed by the left and right surfaces of the railing recessing inward. Plug rods inserted into the device cavity are movably installed inside the concave holes. A quick-release component is installed between the railing and the positioning plate;

[0007] The quick-release component includes a quick-release plate and a hand-twisting rod. Two groups of hand-twisting rods are symmetrically installed on the upper side of the front surface of the quick-release plate. External threads are formed on the rear end surface of the hand-twisting rod. A square groove is formed by the front end of the hand-twisting rod recessing backward. A square rod is assembled inside the square groove, and the front end of the square rod is connected to a turntable.

[0008] As a preferred embodiment, a threaded hole is formed by the backward depression of the front surface of the positioning boss, and a plurality of positioning bosses are evenly installed on the rear surface of the equipment cavity. A coaxial through hole corresponds to the front of each positioning boss, and a plurality of the through holes are evenly formed on the surface of the positioning plate.

[0009] As a preferred embodiment, jacks are provided on the left and right sides in front of each row of the through holes. Multiple groups of the jacks are symmetrically formed on the left and right surfaces of the equipment cavity. The axial heights of the jacks, the through holes, and the threaded holes in the same row are the same.

[0010] As a preferred embodiment, a right-angled groove is formed by the downward depression of the upper side of the rear surface of the railing. Two groups of round rods are symmetrically installed at the position below the right-angled groove on the rear surface of the railing. Concave holes are formed by the inward depression of the left and right surfaces of the railing.

[0011] A spring is fixed at the deep part of the concave hole. One end of the spring is connected to the insertion rod. Strip-shaped grooves communicating with the concave holes are formed through the upper and lower surfaces of the railing. A lever connected to the surface of the insertion rod is installed in the strip-shaped grooves. When in use, when the two levers are pushed in opposite directions, the lever can push the spring to compress. At this time, the insertion rod extends into the concave hole for hiding, which is convenient for the railing to be placed horizontally into the equipment cavity smoothly. When the two ends of the insertion rod are aligned with the two groups of jacks, the spring can reset to make the insertion rod extend into the jacks, playing a role in horizontally fixing the railing inside the equipment cavity. When the insertion rod extends into the jacks, the round rod located at the rear side of the railing can extend into the corresponding through holes, thereby improving the supporting effect of the railing.

[0012] As a preferred embodiment, two groups of round holes are symmetrically formed on the upper side of the front surface of the quick-release plate. Hand-tightening rods are installed in both groups of the round holes. The hand-tightening rods sequentially pass through the round holes and the through holes and enter the threaded holes on the surface of the positioning boss.

[0013] The rear end of the square rod is connected to the bottom of the square groove through a pull rope. An electric meter element is fixed to the center of the front surface of the quick-release plate through a screw. Multiple groups of mesh holes for ventilation are formed through the front and rear surfaces of the quick-release plate. In actual use, the diameters of the round holes and the through holes are both larger than the diameter of the hand-tightening rod, so that the hand-tightening rod can smoothly pass through the round holes and the through holes and be inserted into the positioning boss. The setting of the pull rope can prevent the square rod from being pulled out of the square groove too long and causing the separation of the two. By pre-installing the electric meter on the surface of the quick-release plate, the disassembly and assembly of the electric meter can be completed by removing the quick-release plate, which can also be quickly carried out without tools, improving the quickness of the disassembly and assembly of the electric meter. At the same time, through the ventilation mesh holes and the through holes on the surface of the positioning plate, the heat dissipation of the back of the electric meter can be realized, reducing its temperature.

[0014] As a preferred embodiment, the surface of the hand-twisting rod is wrapped with a fixing ring. The distance from the rear surface of the fixing ring to the rear end of the hand-twisting rod is the same as the distance from the quick-release plate to the bottom of the threaded hole. The installation of the fixing ring enables one end of the hand-twisting rod to extend into the threaded hole, and the quick-release plate can be clamped between the fixing ring and the positioning plate through the fixing ring.

[0015] As a preferred embodiment, a door panel is hinged to the front side of the right surface of the box body, and a plurality of ventilation holes are formed through the lower side of the front surface and the lower side of the rear surface of the door panel.

[0016] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By movably connecting inserting rods to both ends of the railing through springs, and forming inserting holes on the surface of the equipment cavity, the inserting rods can be pushed into the inserting holes by the springs, so that the railing is horizontally installed inside the equipment cavity. The right-angle grooves on the surface of the railing play a role in supporting the quick-release plate. The setting of the positioning boss and the through holes enables the installation of the quick-release plate and the electric meter on the surface of the quick-release plate when the hand-twisting rod penetrates through the quick-release plate and the through holes and inserts into the positioning boss. During use, only by twisting the hand-twisting rod by hand, the quick-release plate together with the electric meter on the surface of the quick-release plate can be quickly disassembled and assembled without carrying tools, improving the quickness of the disassembly and assembly of the electric meter. Moreover, multiple groups of through holes and positioning bosses are provided, which can install the railing at different heights inside the equipment cavity and facilitate the installation of the quick-release plate at different positions on the surface of the positioning plate.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an electric meter box with a tool - free disassembly and assembly structure for an electric meter, including: a box body 100, a railing 300 and a quick - release assembly 400. A device cavity 200 is formed by the front surface of the box body 100 recessing backward. A positioning boss 210 is installed inside the device cavity 200, and a positioning plate 220 located in front of the positioning boss 210 is fixed on the rear side inside the device cavity 200;

[0027] The railing 300 is attached to the surface of the positioning plate 220. Concave holes 310 are formed by the left and right surfaces of the railing 300 recessing inward. Inserting rods 330 inserted into the device cavity 200 are movably installed in the concave holes 310. A quick - release assembly 400 is installed between the railing 300 and the positioning plate 220;

[0028] The quick - release assembly 400 includes a quick - release plate 401 and a hand - tightening rod 410. Two groups of hand - tightening rods 410 are symmetrically installed on the upper side of the front surface of the quick - release plate 401. An external thread 420 is formed on the rear - end surface of the hand - tightening rod 410. A square groove 430 is formed by the front - end surface of the hand - tightening rod 410 recessing backward. A square rod 440 is assembled in the square groove 430, and the front end of the square rod 440 is connected to a turntable 450.

[0029] A threaded hole is formed by the front surface of the positioning boss 210 recessing backward. A plurality of positioning bosses 210 are evenly installed on the rear - side surface of the device cavity 200. A coaxial through hole 230 corresponds to each positioning boss 210 in front, and the plurality of through holes 230 are evenly opened on the surface of the positioning plate 220.

[0030] On both the left and right sides in front of each row of through holes 230, jacks 240 are provided. Multiple groups of jacks 240 are symmetrically arranged on the left and right surfaces of the equipment cavity 200. The axial center heights of the jacks 240, through holes 230, and threaded holes in the same row are the same.

[0031] On the upper side of the rear surface of the railing 300, a right-angled groove is formed by downward depression. Two sets of round rods are symmetrically installed at the position below the right-angled groove on the rear surface of the railing 300. Concave holes 310 are formed by inward depression on both the left and right surfaces of the railing 300.

[0032] A spring 320 is fixed deep in the concave hole 310. One end of the spring 320 is connected to the plug rod 330. Strip-shaped grooves 340 communicating with the concave hole 310 are formed through the upper and lower surfaces of the railing 300. A lever 350 connected to the surface of the plug rod 330 is installed in the strip-shaped groove 340. When in use, when the two levers 350 are toggled in opposite directions, the lever 350 can be made to push the spring 320 to compress. At this time, the plug rod 330 extends into the concave hole 310 for hiding, facilitating the railing 300 to be smoothly placed horizontally inside the equipment cavity 200. When the two ends of the plug rod 330 are aligned with the two sets of jacks 240, the spring 320 can reset to make the plug rod 330 extend into the jack 240, playing a role in horizontally fixing the railing 300 inside the equipment cavity 200. When the plug rod 330 extends into the jack 240, the round rod located at the rear side of the railing 300 can extend into the corresponding through hole 230, thereby improving the support effect of the railing 300.

[0033] On the upper side of the front surface of the quick-release plate 401, two sets of round holes are symmetrically opened. Hand-tightening rods 410 are installed in both sets of round holes. The hand-tightening rods 410 sequentially enter the threaded holes on the surface of the positioning boss 210 through the round holes and through holes 230.

[0034] The rear end of the square rod 440 is connected to the bottom of the square groove 430 through a pull rope. An electric meter component is fixed to the center of the front surface of the quick-release plate 401 through screws. Multiple sets of mesh holes for ventilation are formed through the front and rear surfaces of the quick-release plate 401. When actually in use, the diameters of the round holes and through holes 230 are both larger than the diameter of the hand-tightening rod 410, enabling the hand-tightening rod 410 to smoothly insert into the positioning boss 210 through the round holes and through holes 230. The setting of the pull rope can prevent the square rod 440 from being pulled out of the square groove 430 by too long a distance and causing separation between the two. By pre-installing the electric meter on the surface of the quick-release plate 401, the disassembly and assembly of the electric meter can be completed by removing the quick-release plate 401, which can also be quickly carried out without tools, improving the quickness of the disassembly and assembly of the electric meter. At the same time, through the ventilation mesh holes and the through holes 230 on the surface of the positioning plate 220, heat dissipation of the back of the electric meter can be achieved, reducing its temperature.

[0035] The surface of the hand-twisting rod 410 is wrapped with a fixing ring. The distance from the rear surface of the fixing ring to the rear end of the hand-twisting rod 410 is the same as the distance from the quick-release plate 401 to the bottom of the threaded hole. The installation of the fixing ring enables one end of the hand-twisting rod to extend into the threaded hole. When this happens, the quick-release plate 401 can be clamped between the fixing ring and the positioning plate 220 through the fixing ring.

[0036] A door panel is connected to the front side of the right surface of the box body 100 through a hinge. Multiple groups of ventilation holes are formed by penetrating the lower side of the front surface and the lower side of the rear surface of the door panel.

[0037] Example 1: During actual use, first, toggle the lever 350 to hide the insertion rods 330 at both ends of the railing 300 into the two groups of concave holes 310. When determining the installation position of the electric meter, place the railing 300 at an appropriate height below the installation position of the electric meter, and push the railing 300 so that its rear surface is in contact with the surface of the positioning plate 220. After the insertion rods 330 at both ends of the railing 300 are aligned with the corresponding insertion holes 240, the spring 320 resets and pushes the insertion rods 330 into the slots, fixing the railing 300 horizontally inside the equipment cavity 200. At this time, place the quick-release plate 401 with the electric meter installed on its surface above the railing 300. The bottom of the quick-release plate 401 can be in contact with the inner surface of the right-angle groove. The railing 300 plays a supporting role for the quick-release plate 401 and can slide the quick-release plate 401 left and right to adjust the installation position of the electric meter. Furthermore, when the through hole 230 corresponds exactly behind the round hole on the surface of the quick-release plate 401, insert the hand-twisting rod 410 through the round hole into the corresponding through hole 230. And through the cooperation of the external thread 420 on the surface of the hand-twisting rod 410 and the threaded hole on the surface of the positioning boss 210, the hand-twisting rod 410 can be inserted into the corresponding positioning boss 210 when rotating the hand-twisting rod 410, realizing the fixation of the quick-release plate 401 and the installation of the electric meter pre-fixed on the surface of the quick-release plate 401, and at the same time facilitating quick disassembly.

[0038] Moreover, because multiple groups of through holes 230 are evenly formed on the surface of the positioning plate 220, and multiple groups of insertion holes 240 are formed on the surface of the equipment cavity 200, the railing 300 and the quick-release plate 401 can be installed at multiple positions inside the equipment cavity 200, which is convenient for installation at different positions.

[0039] Embodiment 2: When it is necessary to remove the electric meter on the surface of the quick-release plate 401, operate in reverse according to the above steps. First, screw out the hand-twisting rod 410 from the positioning boss 210 and the through hole 230, so that the hand-twisting rod 410 is separated from the positioning plate 220. If the width of the electric meter exceeds the protruding length of the hand-twisting rod 410, friction between the staff's hand and the electric meter may occur when the hand-twisting rod 410 is turned. At this time, pulling the turntable 450 outwards can make the square rod 440 move in the square groove 430, which plays a role in increasing the use length of the hand-twisting rod 410, making it more convenient to screw the hand-twisting rod 410 away from the positioning plate 220. Even without tools, the quick-release plate 401 and the electric meter on its surface can be quickly disassembled and assembled, improving the quickness of the electric meter disassembly and assembly. The simplified disassembly and assembly process can greatly shorten the maintenance time, thereby reducing the system downtime and maintaining the stability of the power supply.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
