Description

Technical Field

[0001] This application relates to the technical field of electricity meters, and in particular to an installation structure for an electricity meter. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also known as a kilowatt-hour meter, energy meter, etc., and has a very wide range of applications. Currently, most electricity meter terminals and covers are assembled and fixed with bolts, and the lead seal structure usually involves radially drilling holes in the bolts, which are then sealed with lead seals in conjunction with the connecting parts on the terminal cover. This lead seal method prevents the bolts from rotating, thereby preventing the terminal cover from being disassembled.

[0003] The existing publication number CN219658175U, entitled "A Low-Fault Prepaid Electricity Meter," includes a meter housing, a current transformer, a relay, and a circuit board. The meter housing comprises a base housing and a top cover housing; a terminal twist box, detachably disposed on the left side inside the base housing, with several wiring screws respectively cooperating with corresponding wiring frames, and several wiring holes respectively connecting to corresponding wiring cavities; a pin holder disposed inside the base housing, close to the right side of the terminal twist box, and having several pin slots; the input and output pins of the relay extend through the pin slots into the corresponding wiring frames; a pin fixing block is detachably mounted on the pin holder for clamping and fixing the pins, and has several pin fixing screws. The relay pin ends of this invention are not easily deformed.

[0004] Regarding the aforementioned technologies, the inventors discovered that the end cap on the aforementioned electricity meter is mostly fixed to the electricity meter with screws. When disassembling and assembling the cable later, it is necessary to manually remove the fixing screws on the fixed end cap and then remove and install the wiring screws in order to complete the cable replacement. The multiple screw removal and installation steps are cumbersome, making it inconvenient to disassemble and assemble the electricity meter cable. Utility Model Content

[0005] To overcome the problem that existing electricity meters are mostly fixed to the end cap with screws, which requires manual removal of the fixing screws on the end cap and then removal and installation of the wiring screws to replace the cable, this application provides an installation structure for electricity meters.

[0006] The installation structure of the electricity meter provided in this application adopts the following technical solution: An installation structure for an electricity meter includes an electricity meter body, a fixing component, and a cover plate. An end cap is integrally fixed to the bottom surface of the electricity meter body, and the front end face of the end cap is open. A cover plate is assembled at the opening of the end cap. A fixing component is fixed to the rear end face of the electricity meter body. An assembly slide rail and a connecting slide rail are vertically fixed to the vertical end faces of the end cap and the cover plate, respectively. A slide groove frame is vertically fixed to the upper part of the outer vertical end face of the electricity meter body, and a guide slide rail is vertically slidably assembled on the slide groove frame. A snap-fit ​​slide frame is vertically fixed to the bottom end face of the guide slide rail, and the snap-fit ​​slide frame is slidably assembled and snapped with the assembly slide rail and the connecting slide rail on the end cap and the cover plate.

[0007] By adopting the above technical solution, when assembling or disassembling cables on the end cover of the electricity meter body during use, firstly, pull the guide slide in the slide box upwards, and pull the snap-fit ​​slide vertically upwards. The snap-fit ​​slide slides out from the assembly slide and connecting slide on the side wall of the end cover and the cover plate, and remove the cover plate from the end cover. Then, insert the cable through the wire hole on the bottom surface of the end cover into the end cover. After the end of the cable is fixed in the end cover, place the cover plate at the opening of the end cover, push the guide slide in the slide box downwards, and push the snap-fit ​​slide vertically downwards. The snap-fit ​​slide engages with the assembly slide and connecting slide on the side wall of the end cover and the cover plate, ensuring the assembly stability of the end cover and the cover plate. Thus, the snap-fit ​​end cover and the cover plate can be quickly disassembled and assembled without screws, reducing disassembly and assembly steps and improving the convenience of cable assembly and disassembly of the electricity meter body in the later stages.

[0008] Optionally, multiple pressure cylinders are horizontally arranged on the rear end face of the cover plate, and the multiple pressure cylinders are fixed on the rear end face of the cover plate.

[0009] By adopting the above technical solution, the multiple pressure cylinders on the rear end face of the cover plate are made of insulating material, and the multiple pressure cylinders are inserted into the end cap to ensure the stability of the cable end assembly in the later stage.

[0010] Optionally, a compression spring is vertically fixed to the top of the outer vertical end face of the electricity meter body, and the bottom end of the compression spring is fixed to the top surface of the guide rail.

[0011] By adopting the above technical solution, in order to ensure the stability of the snap-fit ​​sliding frame snapping onto the assembly sliding strip and connecting sliding strip on the side wall of the end cap and cover plate, the pressure spring set on the outer wall of the energy meter body is used to push the guide sliding strip to slide vertically on the sliding groove frame, so as to make the snap-fit ​​sliding frame snapping onto the assembly stability of the end cap and cover plate.

[0012] Optionally, the fastener includes a mounting bracket, which is vertically mounted on the rear side of the electricity meter body and is fixed to the installation position by fixing screws.

[0013] By adopting the above technical solution, the mounting bracket is pre-fixed to the installation position of the electricity meter using fixing screws, which is used for quick assembly and support of the electricity meter body later.

[0014] Optionally, the front end face of the fixing frame is horizontally fixed with inserts on both the upper and lower sides, and pressure rings are horizontally slidably inserted into the inserts.

[0015] By adopting the above technical solution, when assembling the supporting energy meter body on the fixed frame, the plug on the fixed frame is inserted through the energy meter body, and the pressure ring presses the energy meter body on the fixed frame to ensure installation stability.

[0016] Optionally, a downward pressure spring is horizontally sleeved on the outside of the insertion post, with one end of the downward pressure spring fixed to the end of the insertion post and the other end of the downward pressure spring pressing against the end of the pressure ring.

[0017] By adopting the above technical solution, in order to ensure the stability of the energy meter body on the fixed frame by sliding the pressure ring on the insertion post, the deformation force of the downward pressure spring is used to push the pressure ring to slide on the insertion post, thereby pushing the energy meter body on the fixed frame to ensure installation stability.

[0018] Optionally, the upper and lower sides of the outer vertical end face of the electricity meter body are fixed with a locking seat, and the locking seat is provided with a locking hole for the pressure ring to pass through.

[0019] By adopting the above technical solution, the locking holes opened on the locking seat fixed to the outer wall of the electricity meter body allow the pressure ring to pass through. During installation, after the pressure ring passes through the locking holes, the pressure ring is rotated to make the locking holes on the locking seat staggered and lock the electricity meter body on the fixing frame. At the same time, during disassembly, the pressure ring is rotated on the insertion post to make the pressure ring coincide with the locking holes on the locking seat and pull it out, thus completing the disassembly of the electricity meter body from the fixing component.

[0020] Optionally, the inside of the end cap has multiple horizontally fixed terminals, and multiple pressure cylinders are slidably fitted with the multiple terminals.

[0021] By adopting the above technical solution, multiple pressure cylinders are inserted into the end cap, and the multiple pressure cylinders and multiple terminals are slidably fitted together to ensure the stability of the cable end assembly in the later stage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When assembling or disassembling cables on the end cover of the electricity meter body, first pull the guide slide in the slide box upwards, then pull the snap-fit ​​slide frame vertically upwards. The snap-fit ​​slide frame slides out from the assembly slide and connecting slide on the side wall of the end cover and the cover plate, removing the cover plate from the end cover. Then, insert the cable through the wire hole on the bottom of the end cover into the end cover. After fixing the cable end in the end cover, place the cover plate at the opening of the end cover, push the guide slide in the slide box downwards, and push the snap-fit ​​slide frame vertically downwards. The snap-fit ​​slide frame snaps into the assembly slide and connecting slide on the side wall of the end cover and the cover plate, ensuring the assembly stability of the end cover and the cover plate. This snap-fit ​​design allows for quick assembly and disassembly without screws, reducing assembly and disassembly steps and improving the convenience of cable assembly and disassembly of the electricity meter body in the future.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses an installation structure for an electricity meter. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4An installation structure for an electricity meter includes an electricity meter body 1, a fixing component 2, and a cover plate 3. An end cap 12 is integrally fixed on the bottom surface of the electricity meter body 1, and the front end face of the end cap 12 is open. A cover plate 3 is assembled at the opening of the end cap 12. A fixing component 2 is fixed on the rear end face of the electricity meter body 1. An assembly slide 14 and a connecting slide 31 are vertically fixed on the vertical end faces of the end cap 12 and the cover plate 3, respectively. A sliding groove frame 18 is vertically fixed on the upper part of the outer vertical end face of the electricity meter body 1, and a guide slide 16 is vertically slidably assembled on the sliding groove frame 18. A snap-fit ​​slide frame 15 is vertically fixed on the bottom end face of the guide slide 16, and the snap-fit ​​slide frame 15 is slidably assembled and snapped with the assembly slide 14 and the connecting slide 31 on the end cap 12 and the cover plate 3. When installing or removing cables from the end cover 12 of the electricity meter body 1 during use, first pull the guide slide 16 in the slide frame 18 upwards, and pull the locking slide frame 15 vertically upwards. The locking slide frame 15 slides out from the assembly slide 14 and connecting slide 31 on the side wall of the end cover 12 and the cover plate 3. Remove the cover plate 3 from the end cover 12. Then, insert the cable through the wire hole on the bottom surface of the end cover 12 into the end cover 12. After the end of the cable is fixed in the end cover 12, then remove the cover plate 3. The guide slide 16 in the sliding frame 18 is pushed down at the opening of the end cover 12, which pushes the snap-fit ​​slide 15 to move vertically downward. The snap-fit ​​slide 15 snaps onto the assembly slide 14 and connecting slide 31 on the side wall of the end cover 12 and the cover plate 3, ensuring the assembly stability of the end cover 12 and the cover plate 3. The snap-fit ​​end cover 12 and the cover plate 3 can be quickly disassembled without screws, reducing disassembly and assembly steps and improving the convenience of cable disassembly and assembly of the power meter body 1 in the later stage.

[0027] Reference Figure 3 Multiple pressure cylinders 32 are horizontally arranged on the rear end face of the cover plate 3, and are fixed to the rear end face of the cover plate 3. The multiple pressure cylinders 32 on the rear end face of the cover plate 3 are made of insulating material. These multiple pressure cylinders 32 are inserted into the end cap 12 to ensure stability during subsequent cable end assembly. Multiple terminals 13 are horizontally fixed inside the end cap 12, and the multiple pressure cylinders 32 are slidably fitted onto the terminals 13. The multiple pressure cylinders 32 are inserted into the end cap 12, and are slidably fitted onto the terminals 13 to ensure stability during subsequent cable end assembly.

[0028] Reference Figure 3 and Figure 4A compression spring 17 is vertically fixed to the top of the outer vertical end face of the electricity meter body 1, and the bottom end of the compression spring 17 is fixed to the top surface of the guide slide 16. In order to ensure the stability of the snap-fit ​​slide frame 15 in the later snap-fit ​​assembly slide 14 and connecting slide 31 on the side wall of the end cover 12 and the cover plate 3, the compression spring 17 set on the outer wall of the electricity meter body 1 is used to push the guide slide 16 to slide vertically on the slide groove frame 18, so as to make the snap-fit ​​slide frame 15 snap-fit ​​assembly of the end cover 12 and the cover plate 3 stable.

[0029] Reference Figure 4 and Figure 5 The fixing component 2 includes a fixing frame 21, which is vertically mounted on the rear side of the energy meter body 1 and fixed in the installation position by fixing screws 22. The fixing frame 21 is pre-fixed to the installation position of the energy meter using fixing screws 22 for quick assembly and support of the energy meter body 1 later. Inserts 23 are horizontally fixed on both the upper and lower sides of the front end face of the fixing frame 21, and pressure rings 24 are horizontally slidably inserted into the inserts 23. When assembling the energy meter body 1 on the fixing frame 21, the inserts 23 on the fixing frame 21 penetrate and insert into the energy meter body 1, and the pressure rings 24 press the energy meter body 1 to ensure installation stability on the fixing frame 21. A downward pressure spring 25 is horizontally sleeved on the outside of the inserts 23, with one end of the downward pressure spring 25 fixed to the end of the insert 23 and the other end pressing against the end of the pressure ring 24. To ensure the stability of the meter body 1 on the fixing frame 21 by sliding the pressure ring 24 on the insertion post 23, the deformation force of the downward pressure spring 25 is used to push the pressure ring 24 to slide on the insertion post 23, thus ensuring the installation stability of the meter body 1 on the fixing frame 21. Both the upper and lower sides of the outer vertical end face of the meter body 1 are fixed with locking holes 11, and the locking holes 11 have through holes for the pressure ring 24 to pass through. The locking holes on the locking holes 11 fixed to the outer wall of the meter body 1 allow the pressure ring 24 to pass through. During installation, after the pressure ring 24 passes through the locking holes, rotating the pressure ring 24 causes the locking holes on the locking holes 11 to be staggered and engage the meter body 1 on the fixing frame 21. Simultaneously, during disassembly, rotating the pressure ring 24 on the insertion post 23 causes the pressure ring 24 to align with the locking holes on the locking holes 11 and pull it out, completing the disassembly of the meter body 1 from the fixing component 2.

[0030] The implementation principle of the installation structure of an electricity meter according to this application embodiment is as follows: When assembling or disassembling the cable on the end cover 12 of the electricity meter body 1 during use, firstly, the guide slide 16 in the slide frame 18 is pulled upward, compressing the spring 17 upward and deforming it, pulling the locking slide frame 15 vertically upward. The locking slide frame 15 slides out from the assembly slide 14 and connecting slide 31 on the side wall of the end cover 12 and the cover plate 3, and the cover plate 3 is removed from the end cover 12. Then, the cable is passed through the wire hole on the bottom surface of the end cover 12 and inserted into the end cover 12. After the end of the cable is fixed in the end cover 12, the cover plate 3 is placed at the opening of the end cover 12. The guide slide 16 is released, the deformation force of the spring 17 is used to push the guide slide 16 in the slide frame 18 downward, and push the locking slide frame 15 vertically. Moving downwards, the snap-fit ​​sliding frame 15 snaps onto the assembly sliding strip 14 and connecting sliding strip 31 on the side wall of the end cap 12 and the cover plate 3. The multiple pressure cylinders 32 on the rear end face of the cover plate 3 are made of insulating material. At the same time, the multiple pressure cylinders 32 are inserted into the end cap 12 to ensure the stability of the cable end assembly later. The assembly of the end cap 12 and the cover plate 3 is completed. The snap-fit ​​holes on the snap-fit ​​seat 11 fixed on the outer wall of the energy meter body 1 allow the pressure ring 24 to pass through. During installation, after the pressure ring 24 passes through the snap-fit ​​hole, rotate the pressure ring 24 to make the snap-fit ​​holes on the snap-fit ​​seat 11 staggered and snap the energy meter body 1 onto the fixing frame 21. At the same time, during disassembly, rotate the pressure ring 24 on the insertion post 23 to make the pressure ring 24 coincide with the snap-fit ​​hole on the snap-fit ​​seat 11 and pull it out, completing the disassembly of the energy meter body 1 from the fixing part 2.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
