Description

Technical Field

[0001] The present invention relates to the technical field of electricity meters, and particularly to an electricity meter that is easy to install. Background Art

[0002] An electricity meter is an instrument used to measure various electrical quantities. According to the circuits it uses, it can be divided into DC electricity meters and AC electricity meters. AC electricity meters can be further divided into single-phase electricity meters, three-phase three-wire electricity meters, and three-phase four-wire electricity meters according to their phase lines. Electricity meters are widely used in households, industries, and power systems, and are usually directly installed on the wall surface.

[0003] The installation method of traditional electricity meters generally relies on bolt fixation, which has the problems of cumbersome installation steps and long time consumption. Moreover, corresponding tools are needed for disassembly, resulting in high maintenance costs. After the bolts are disassembled and installed multiple times, their threads or installation holes will gradually wear due to friction, causing loosening, thus affecting the installation stability of the electricity meter. Summary of the Invention

[0004] In order to overcome the shortcoming of cumbersome installation steps of electricity meters, the present invention provides an electricity meter that is easy to install.

[0005] The technical implementation solution of the present invention is: an electricity meter that is easy to install, including a bottom plate, an electricity meter main body, a mounting plate, a support seat, a shock absorption component, a fixed seat, a rotating frame, a sliding block, a pressing frame, and a pressing block. The mounting plate is provided on the back side of the electricity meter main body. The bottom plate is provided with a support seat and two fixed seats. The support seat is provided with a shock absorption component. Two rotating frames are rotatably provided on the shock absorption component. Extrusion grooves are provided on both rotating frames. Sliding blocks are rotatably provided at the ends of the two rotating frames away from the shock absorption component. The two sliding blocks are respectively slidably connected to the two pressing frames. The pressing frames are slidably connected to the fixed seats. Pressing blocks are provided at the lower ends of both sides of the mounting plate. The shape of the extrusion groove is adapted to the pressing block.

[0006] As a further preferred solution, it further includes a connecting rod, a moving rod, a receiving member, a first elastic member, an embedding block, and a second elastic member. A receiving groove is opened inside the upper part of the mounting plate. A pulling mechanism is slidably provided in the receiving groove. Two connecting rods are rotatably provided at the lower end of the pulling mechanism. The two connecting rods are respectively rotatably connected to a moving rod. The moving rod is slidably connected to the receiving groove of the mounting plate. A receiving member is provided at the end of the moving rod away from the connecting rod. A first elastic member is sleeved outside the moving rod. The first elastic member connects the receiving member and the mounting plate. An embedding block is slidably provided in the receiving member. A second elastic member is connected between the receiving member and the embedding block. An embedding groove adapted to the embedding block is opened on the pressing frame.

[0007] As a further preferred solution, the pulling mechanism includes a pulling rod, a limiting rod, a moving sleeve and a torsion spring. The upper part of the mounting plate is slidably provided with the pulling rod, the lower part of the pulling rod is provided with the limiting rod, the upper end shape of the accommodating groove is adapted to the pulling rod and the limiting rod, the lower part of the pulling rod is rotatably provided with the moving sleeve, a torsion spring is connected between the moving sleeve and the pulling rod, and the moving sleeve is rotatably connected to the two connecting rods.

[0008] As a further preferred solution, it further includes a pressure sensor and an alarm. The pressure sensor is installed in the accommodating groove, the limiting rod contacts the pressure sensor, the alarm is installed on the mounting plate, and the pressure sensor and the alarm are electrically connected.

[0009] As a further preferred solution, the damping component includes a sliding frame and a third elastic member. The support base is slidably provided with the sliding frame, and a third elastic member is connected between the sliding frame and the support base.

[0010] As a further preferred solution, it further includes a protective shell. Two protective shells are provided on the bottom plate, and the fixing seat, the rotating frame, the sliding block and the pressing frame are all located inside the protective shell.

[0011] As a further preferred solution, positioning grooves are formed in the upper parts of the opposite sides of the two protective shells.

[0012] As a further preferred solution, fixing grooves are formed on both sides of the pressing frame, and convex blocks adapted to the fixing grooves are provided inside the protective shell. When the main body of the electric energy meter is not installed, the convex blocks are embedded into the fixing grooves.

[0013] As a further preferred solution, it further includes a dovetail block. The dovetail block is provided on the bottom plate, and the mounting plate is slidably connected to the dovetail block.

[0014] The beneficial effects of the present invention are as follows: 1.

Through the cooperation of the embedding block and the embedding groove, the present invention locks the main body of the electric energy meter on the bottom plate to ensure the stability of the installation, prevent the main body of the electric energy meter from accidentally falling off, and at the same time, no tools are required for disassembly. Just rotate the pulling rod by ninety degrees and then lift it to directly unlock the main body of the electric energy meter. The operation is simple and efficient, significantly reducing the maintenance cost and time.

[0016] 3. By setting the pressure sensor and the alarm, when the electric energy meter is illegally disassembled (lifting directly without rotating the pulling rod), the limiting rod squeezes the pressure sensor to trigger the alarm to sound, playing a role of anti-theft warning, reminding the surrounding people of illegal operation behaviors, and ensuring the safety of the equipment.

Detailed implementation manners

[0031] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] An easily installable electricity meter, as Figures 1 - 6 shown, includes a bottom plate 1, an electricity meter main body 2, a mounting plate 3, a support seat 5, a shock absorption assembly, a fixing seat 6, a rotating frame 7, a sliding block 8, a pressing frame 9 and a pressing block 10. The mounting plate 3 is provided on the back side of the electricity meter main body 2. The support seat 5 and two fixing seats 6 are provided on the bottom plate 1. The two fixing seats 6 are respectively located at both ends of the bottom plate 1. The shock absorption assembly is provided on the support seat 5. Rotating frames 7 are rotatably provided at both ends of the upper side of the shock absorption assembly. Extrusion grooves 701 are provided at the lower parts of the opposite sides of the two rotating frames 7. Sliding blocks 8 are rotatably provided at the ends of the two rotating frames 7 away from the shock absorption assembly. The two sliding blocks 8 are respectively slidably connected to the two pressing frames 9. The pressing frame 9 is slidably connected to the fixing seat 6. Pressing blocks 10 are provided at the lower ends of both sides of the mounting plate 3. The shape of the extrusion groove 701 is adapted to the pressing block 10. Arc chamfers are provided on both the upper and lower sides of the extrusion groove 701.

[0033] During installation, the electricity meter main body 2 is inserted between the two fixing seats 6 on the bottom plate 1. The pressing block 10 on the mounting plate 3 will contact the lower side of the extrusion groove 701 of the rotating frame 7. Since both the shock absorption assembly and the sliding block 8 are rotatably connected to the rotating frame 7, the rotating frame 7 will rotate under the pressure of the pressing block 10. The sliding block 8 rotates synchronously with the rotating frame 7, and the rotation center is the connection part of the shock absorption assembly and the rotating frame 7. At the same time, the pressing frame 9 will gradually approach the mounting plate 3 under the action of the sliding block 8. When the pressing block 10 is completely embedded in the extrusion groove 701, the pressing frame 9 contacts the mounting plate 3 and presses and fixes it; when it is necessary to disassemble the electricity meter main body 2, the electricity meter main body 2 is lifted upward, and the pressing block 10 will press the upper side of the extrusion groove 701 of the rotating frame 7. Similarly, the rotating frame 7, the sliding block 8 and the pressing frame 9 will be reset accordingly, and the disassembly of the electricity meter main body 2 is completed.

[0034] As Figures 7 - 10As shown in the figure, it further includes a connecting rod 15, a moving rod 16, a receiving member 17, a first elastic member 18, an embedding block 19 and a second elastic member 20. An accommodation groove 301 is formed in the inner side of the upper part of the mounting plate 3. A pulling mechanism is slidably arranged in the accommodation groove 301. Two connecting rods 15 are rotatably arranged at the lower end of the pulling mechanism. The two connecting rods 15 are respectively rotatably connected with a moving rod 16. The moving rod 16 is slidably connected with the accommodation groove 301 of the mounting plate 3. A receiving member 17 is arranged at one end of the moving rod 16 away from the connecting rod 15. A receiving groove is formed in the receiving member 17. A first elastic member 18 is sleeved outside the moving rod 16. The first elastic member 18 connects the receiving member 17 and the mounting plate 3. An embedding block 19 is slidably arranged in the receiving groove of the receiving member 17. The embedding block 19 can be completely embedded in the receiving groove of the receiving member 17. A second elastic member 20 is connected between the receiving member 17 and the embedding block 19. An embedding groove 902 adapted to the embedding block 19 is formed in the pressing frame 9. During installation, the mounting plate 3 moves downward, and the pressing frame 9 gradually approaches the mounting plate 3. The embedding block 19 will first contact the pressing frame 9 and be embedded into the receiving member 17 under the action of the pressing frame 9. When the embedding block 19 is aligned with the embedding groove 902 of the pressing frame 9, the pressing frame 9 no longer presses the embedding block 19, and the embedding block 19 is embedded into the embedding groove 902 under the action of the second elastic member 20, locking the electricity meter main body 2 on the bottom plate 1. When it is necessary to disassemble the electricity meter main body 2, lift the pulling mechanism upward. Since both the pulling mechanism and the moving rod 16 are rotatably connected with the connecting rod 15, the pulling mechanism will drive the connecting rod 15 to rotate. The connecting rod 15 will pull the moving rod 16 to approach the pulling mechanism. At this time, the first elastic member 18 contracts. The connecting rod 15 will pull the receiving member 17 and the embedding block 19 thereon to move. The embedding block 19 disengages from the embedding groove 902. At this time, the electricity meter main body 2 can be directly lifted by the pulling mechanism to complete the disassembly. Then release the pulling mechanism, and the first elastic member 18 drives the moving rod 16 to reset. The moving rod 16 drives the pulling mechanism, the connecting rod 15, the receiving member 17 and the embedding block 19 to reset.

[0035] As Figures 7 - 10As shown in the figure, the pulling mechanism includes a pulling rod 11, a limiting rod 12, a moving sleeve 13 and a torsion spring 14. The upper part of the mounting plate 3 is slidably provided with the pulling rod 11, and the lower part of the pulling rod 11 is provided with the limiting rod 12. The upper end shape of the receiving groove 301 is adapted to the pulling rod 11 and the limiting rod 12, and can slide up and down inside the receiving groove 301 after the limiting rod 12 rotates 90 degrees. The lower part of the pulling rod 11 is rotatably provided with the moving sleeve 13. The receiving groove 301 restricts the moving sleeve 13 to slide only in the up and down direction. A torsion spring 14 is connected between the moving sleeve 13 and the pulling rod 11. The moving sleeve 13 is rotatably connected to two connecting rods 15. When disassembling the electricity meter main body 2, if the pulling rod 11 is directly lifted upward, the limiting rod 12 will be restricted by the receiving groove 301 of the mounting plate 3, resulting in the pulling rod 11 being unable to be lifted, that is, directly lifting the pulling rod 11 upward cannot unlock the electricity meter main body 2. The pulling rod 11 needs to be rotated 90 degrees. The pulling rod 11 drives the limiting rod 12 to rotate, and the torsion spring 14 deforms. At this time, the receiving groove 301 no longer restricts the limiting rod 12, and the pulling rod 11 can be lifted, thereby unlocking the electricity meter main body 2. After unlocking, the pulling rod 11 is released, and the first elastic member 18 drives the moving rod 16 to reset. The moving rod 16 pulls the moving sleeve 13 and the pulling rod 11 thereon to reset through the connecting rod 15. After the pulling rod 11 resets, the torsion spring 14 drives the pulling rod 11 and the limiting rod 12 thereon to rotate 90 degrees in the reverse direction to reset.

[0036] As Figures 7 - 8 shown, it further includes a pressure sensor 21 and an alarm 22. Two pressure sensors 21 are installed in the receiving groove 301, and both ends of the limiting rod 12 are in contact with the two pressure sensors 21 respectively. After the limiting rod 12 rotates 90 degrees, the pressure sensor 21 is no longer in contact with the limiting rod 12. The alarm 22 is installed on the mounting plate 3, and the pressure sensor 21 and the alarm 22 are electrically connected. When disassembling the electricity meter main body 2, if the operator directly lifts it upward without rotating the pulling rod 11 according to the correct operation, the limiting rod 12 will squeeze the pressure sensor 21. The pressure sensor 21 transmits a signal to the alarm 22, and the alarm 22 emits an alarm, playing a role of anti-theft warning, reminding the surrounding people of illegal operation behavior. Only after rotating the pulling rod 11 according to the correct operation, the pressure sensor 21 is no longer in contact with the limiting rod 12. At this time, lifting the pulling rod 11 will not trigger the alarm.

[0037] As Figure 11 shown, the shock absorption assembly includes a sliding frame 23 and a third elastic member 24. The sliding frame 23 is slidably provided on the support seat 5, and a third elastic member 24 is connected between the sliding frame 23 and the support seat 5. The vibration generated during installation or use is absorbed by the elastically connected sliding frame 23, reducing the mechanical damage of the electricity meter main body 2 and extending the service life of the equipment.

[0038] As Figure 1As shown, it further includes a protective shell 4. There are two protective shells 4 on the bottom plate 1, and the fixing seat 6, the rotating frame 7, the sliding block 8 and the pressing frame 9 are all located inside the protective shell 4. The protective shell 4 plays a protective role, preventing these components from being affected by external collisions, dust, etc., and ensuring the normal operation and stability of the equipment.

[0039] On the upper part of the opposite sides of the two protective shells 4, positioning grooves 401 are provided. The positioning grooves 401 provide a positioning reference for installing the electricity meter main body 2, facilitating the operator to accurately place the electricity meter main body 2 at the appropriate position on the bottom plate 1, and improving the installation efficiency and accuracy.

[0040] Fixing grooves 901 are provided on both sides of the pressing frame 9, and convex blocks adapted to the fixing grooves 901 are provided inside the protective shell 4. When the electricity meter main body 2 is not installed, the convex blocks are embedded in the fixing grooves 901. It plays a fixing role for the pressing frame 9, preventing the pressing frame 9 from shaking randomly, and maintaining the stability of the equipment in the uninstalled state.

[0041] As Figure 5 shown, it further includes a dovetail block 101. The dovetail block 101 is provided on the bottom plate 1, and the mounting plate 3 is slidably connected to the dovetail block 101. The dovetail block 101 provides a guiding role for the installation and disassembly of the mounting plate 3 on the bottom plate 1, enabling the mounting plate 3 to move accurately along the dovetail block 101, and ensuring the smoothness of the installation process and the accuracy of the installation position of the electricity meter main body 2.

[0042] The above are only examples of the present invention and are not used to limit the present invention.

The content not elaborated in detail in the present invention belongs to the known prior art of those skilled in the art.
