Description

Technical Field

[0001] The invention relates to the technical field of electric energy meters, and in particular to an electric energy meter which is easy to install and disassemble. Background Art

[0002] The electric energy meter is an instrument used to measure electric energy, which is usually installed in the distribution box. The electric energy meter is a measuring instrument used to record the amount of electricity used by the user. All electricity consumption of the user should pass through the electric energy meter to facilitate the observation of the amount of electricity consumption.

[0003] When installing an existing electric energy meter, the electric energy meter is usually fixed to the bracket inside the electrical box by screws so that it is firmly fixed in the distribution box. Usually, the bracket has a long hole for convenient installation and matching position. However, since the position of the bracket inside the electrical box is fixed, the screw positions on electric energy meters of different models are also different. Therefore, when the screws on the electric energy meter do not match the position of the long holes on the bracket, the screws cannot be screwed into the mounting holes, affecting the installation of the electric energy meter. For this situation, in most cases, the screws are directly screwed through the bracket body, which requires the installer to add a professional electric screwdriver. In addition, the internal space of the electrical box is small, which is not conducive to the use of an electric screwdriver. Therefore, the existing installation method of the electric energy meter is relatively cumbersome and not conducive to the rapid installation and disassembly of the electric energy meter.

[0004] When wiring, you first need to remove the terminal box cover. In real life, the terminal box cover of the energy meter and the screws on the terminal box cover are very easy to lose, which will cause the terminals to be exposed to the air, posing a safety hazard. After inserting the wires, you need to use a screwdriver to tighten the bolts on each terminal, and then install the terminal box cover.

[0005] However, when disassembling and replacing the energy meter, it is necessary to loosen the screws of each terminal in order to remove all the wires. On the other hand, the removed wires are all exposed to the air. In order to avoid short circuits between the wires or accidental touch by the installer during maintenance, it is also necessary to wrap the wires with insulating tape for protection. The operation process is relatively cumbersome, which makes the efficiency of replacing or repairing the energy meter low.

[0006] Therefore, based on the defects of the prior art, the present invention provides an electric energy meter that is easy to install and disassemble to solve the above problems. Summary of the invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an electric energy meter that is easy to install and disassemble, so as to solve the problem in the prior art that when the positions of the screws on the electric energy meter and the long holes on the bracket do not match, the screws cannot be screwed into the screw holes, affecting the installation of the electric energy meter; the operation process is relatively cumbersome when disassembling and replacing the electric energy meter, resulting in low efficiency in replacing or repairing the electric energy meter.

[0042] The following will refer to the attached Figure 1 To Attachment Fig.13 Various embodiments of the present invention are described in detail.

[0043] Embodiment 1, as attached Figure 1-Figure 13 As shown, an electric energy meter that is easy to install and disassemble comprises an electric energy meter body 1, wherein the rear side surface of the electric energy meter body 1 is provided with two disassembly adjustment slots 2 that are symmetrical in upper and lower positions, and a disassembly plate 3 is installed in each of the disassembly adjustment slots 2 for sliding up and down, and disassembly holes 4 are penetrated front and back at both left and right ends of the disassembly plate 3, and the height of the two disassembly plates 3 is adjusted by sliding up and down, thereby adjusting the height of the disassembly holes 4 so that they can be positioned between the long holes on the bracket, thereby avoiding the situation that the screw and the mounting hole position do not correspond to each other and cannot be installed, and a disassembly plug rod 5 is installed in each of the disassembly holes 4, and each of the disassembly plug rods 5 is installed in each of the disassembly holes 4. A quick disassembly assembly 6 is installed between the rod 5 and the disassembly hole 4. The electric energy meter body 1 is quickly installed by using the disassembly rod 5 instead of screws. When in use, the disassembly rod 5 can be directly inserted into the long hole on the bracket, and the quick disassembly assembly 6 can automatically fix the electric energy meter body 1 and the bracket, eliminating the installation personnel's installation steps using a screwdriver. When disassembling, it is only necessary to twist the disassembly rod 5 90° to release the limit of the electric energy meter body 1 by the quick disassembly assembly 6, so that the electric energy meter body 1 can be quickly removed from the long hole of the bracket, making the electric energy meter body 1 easier to install and disassemble, and improving the installation efficiency;

[0044] A terminal board 7 is fixedly installed below the front side of the electric energy meter body 1, and a plurality of terminal slots 8 are provided at the bottom of the terminal board 7, and a terminal 9 is inserted inside each of the terminal slots 8. A terminal quick-release plate 10 is detachably installed on the front side of the terminal board 7, and a terminal disassembly assembly 11 is installed inside the terminal quick-release plate 10, and the terminal disassembly assembly 11 can fix each terminal 9 and clamp the wires;

[0045] Different from the existing electric energy meter, when removing the wires, it is necessary to loosen the screws of each wire terminal, the wiring terminal 9 in the present invention is fixed and limited by the terminal disassembly assembly 11, and the terminal quick-release plate 10 is the installation base of multiple terminal disassembly assembly assemblies 11. When the terminal quick-release plate 10 is directly removed, the multiple terminal disassembly assembly assemblies 11 can be directly removed. Therefore, when all the wires need to be removed, the terminal quick-release plate 10 can be directly disassembled. At this time, the multiple terminal disassembly assembly assemblies 11 are also removed at the same time, so that all the wiring terminals 9 are free from restrictions and can automatically pop out from the inside of the multiple terminal slots 8 to the outside, so as to achieve the purpose of quickly disassembling all the wiring terminals 9, avoiding the operation of the existing electric energy meter that needs to loosen the screws one by one and then pull out the wires. Moreover, the outer overall material of the wiring terminal 9 of the present invention is an insulating material, and only the inside has a conductive material. Therefore, when the wiring terminal 9 is ejected, the wire is inside the wiring terminal 9, and even if the installer touches the wiring terminal 9, there will be no danger of electric shock, and short circuit between the wires can be avoided;

[0046] When only one of the wiring terminals 9 needs to be disassembled and installed, it is only necessary to loosen the terminal disassembly assembly 11 corresponding to the wiring terminal 9 to make the wiring terminal 9 pop out. During installation, the wiring terminal 9 is inserted into the corresponding terminal slot 8, and the corresponding terminal disassembly assembly 11 is tightened to fix the wiring terminal 9. The main purpose of this embodiment is to enable all the wiring terminals 9 to be quickly disassembled at the same time.

[0047] Embodiment 2, based on embodiment 1, as shown in the attached Figure 3-Figure 5As shown, the disassembly plate 3 is composed of a disassembly plate body 12 and a disassembly telescopic plate 13. Disassembly and telescopic grooves 14 are provided at the left and right ends of the disassembly plate body 12. A disassembly and telescopic plate 13 is slidably installed in each of the disassembly and telescopic grooves 14. A disassembly and telescopic spring 15 fixedly connected to the disassembly and telescopic plate 13 is fixedly installed inside the disassembly and telescopic grooves 14. During installation, the height of the disassembly plate body 12 can be adjusted according to the position of the long hole on the bracket. If the long hole and the disassembly and telescopic rod 5 are misaligned in the left and right directions, the disassembly and telescopic plate 13 can be pulled to be correspondingly telescoped in the disassembly and telescopic groove 14 until the disassembly and telescopic rod 5 corresponds to the long hole and is inserted into the long hole. When the disassembly and telescopic plate 13 is telescoped, the disassembly and telescopic spring 15 can be stretched, and the disassembly and telescopic plate 13 can be reset after disassembly. Through the above operation, the electric energy meter body 1 can be quickly installed on different brackets.

[0048] Embodiment 3, based on embodiment 2, as shown in the attached Figure 3-Figure 5 As shown, a disassembly plate adjusting screw 16 is rotatably installed in each of the disassembly and assembly adjusting slots 2, and the disassembly and assembly plate adjusting screw 16 threadably penetrates the middle part of the disassembly and assembly plate body 12, and the disassembly and assembly plate adjusting screw 16 is connected to an adjusting knob 17. Turning the adjusting knob 17 can drive the disassembly and assembly plate adjusting screw 16 to rotate, thereby driving the disassembly and assembly plate body 12 to move up and down in the disassembly and assembly adjusting slot 2 for adjustment.

[0049] Embodiment 4, based on embodiment 2, as shown in the attached Figure 8-Figure 13 As shown, the quick disassembly assembly 6 includes a plunger wedge slot 18, a plunger wedge 19, a plunger wedge spring 20, an abutment ring 33, a plunger knob 21, and a plunger spring 22;

[0050] Two plunger wedge slots 18 symmetrical with respect to their axis are provided on the rear end outer surface of the disassembling and assembling plunger 5, and a plunger wedge 19 is slidably installed in the interior of each of the plunger wedge slots 18, and the inclined surface of the plunger wedge 19 faces rearward, and a plunger wedge spring 20 connected to the plunger wedge 19 is fixedly installed in each of the plunger wedge slots 18. When the two plunger wedges 19 are on the outer sides of the plunger wedge slots 18, the distance between the tips of the two plunger wedges 19 is less than the length of the long side of the long hole. An abutment ring 33 coaxial with the disassembling hole 4 is fixedly installed on the rear side surface of the disassembling and telescopic plate 13, and the plunger wedge 19 is on the inner side of the abutment ring 33. A plunger knob 21 is fixedly installed at the front end of the disassembling and assembling plunger 5, and a plunger spring 22 located between the disassembling plate 3 and the plunger knob 21 is sleeved and installed on the outer side of the disassembling and assembling plunger 5;

[0051] When in use, the abutment ring 33 can be abutted against the surface of the bracket (such as the attached Fig.13), and then the rod knob 21 can be held to insert the disassembly rod 5 into the long hole of the bracket (the rod spring 22 is compressed during insertion). During insertion, the long hole can squeeze the inclined surfaces of the two rod wedges 19, thereby squeezing the two rod wedges 19 into the two rod wedge grooves 18 and compressing the rod wedge spring 20. After the two rod wedges 19 pass through the long hole, they can pop out under the elastic force of the two rod wedge springs 20, thereby realizing the installation and limiting of the disassembly rod 5;

[0052] The disassembly rod 5 can also be rotated 90° so that the two rod wedges 19 are in the left and right orientation. At this time, they can be directly inserted into the long hole of the bracket, and then the disassembly rod 5 is rotated back 90° so that the two rod wedges 19 return to the upper and lower positions for limiting.

[0053] As attached Fig.13 As shown, after the disassembly and assembly plug 5 is inserted into the long hole (when the disassembly and assembly plug 5 is manually inserted, it will definitely be inserted to a certain depth), the disassembly and assembly plug 5 can be moved forward under the elastic force of the plug spring 22, so that the planes of the two plug wedges 19 abut against the inner side surface of the bracket, and similarly, the front side surface of the disassembly and assembly telescopic plate 13 will also be squeezed by the elastic force of the plug spring 22, and under this elastic force, the four abutment rings 33 abut against the bracket, thereby preliminarily realizing the rapid installation of the electric energy meter body 1.

[0054] Embodiment 5, based on embodiment 4, as shown in the attached Figure 8-Figure 13 As shown, the quick disassembly assembly 6 also includes a disassembly plate wedge block slot 23, a wedge block slot cover plate 24, a disassembly plate wedge block spring 25, a disassembly plate wedge block 26, and a disassembly plate limit wedge block 27;

[0055] A disassembly plate wedge slot 23 is penetrated between the disassembly hole 4 and the top and bottom surfaces of the disassembly and telescopic plate 13, and a wedge slot cover plate 24 located inside the disassembly plate wedge slot 23 is fixedly installed on the top and bottom surfaces of the disassembly and telescopic plate 13, and the wedge slot cover plate 24 can be fixed by screws. Each of the wedge slot cover plates 24 is fixedly installed with a disassembly plate wedge spring 25 located inside the disassembly plate wedge slot 23, and the other end of each of the disassembly plate wedge springs 25 is fixedly installed with a disassembly plate wedge 26 located inside the disassembly hole 4, and the inclined surface of the disassembly plate wedge 26 faces backward, and a plurality of disassembly plate limiting wedges 27 equidistantly distributed in the front and rear directions are fixedly installed on the upper and lower sides of the outer side surface of the disassembly and insertion rod 5, and the inclined surface of the disassembly plate limiting wedge 27 faces forward;

[0056] In combination with the fourth embodiment, when this embodiment is in use, due to the clamping connection between the disassembly plate wedge block 26 and the disassembly plate limiting wedge block 27, the disassembly rod 5 cannot be directly inserted into the long hole of the bracket. At this time, the installer can hold the rod knob 21 to rotate the disassembly rod 5 90 degrees, so that the disassembly plate limiting wedge block 27 on the outside of the disassembly rod 5 is in the left and right direction, thereby separating from the disassembly plate wedge block 26. At this time, the disassembly rod 5 can be inserted into the long hole of the bracket. After the disassembly rod 5 is inserted, the disassembly rod 5 is rotated back 90 degrees, so that the disassembly plate limiting wedge block 27 on its outside returns to the upper and lower position, and re-engages with the two disassembly plate wedge blocks 2 6 is engaged, and then the disassembling plug rod 5 moves forward under the elastic force of the plug rod spring 22, so that the planes of the two plug rod wedge blocks 19 abut against the inner side of the bracket. When the disassembling plug rod 5 moves forward, the inclined surface of the front side of the part of the disassembling plate limiting wedge block 27 can continuously squeeze the inclined surfaces of the two disassembling plate wedge blocks 26, so that the two disassembling plate wedge blocks 26 slide into the disassembling plate wedge block groove 23. When the planes of the two plug rod wedge blocks 19 abut against the inner side of the bracket, the disassembling plug rod 5 stops moving. At this time, the disassembling telescopic plate 13 can be limited in the front and rear directions by the two plug rod wedge blocks 19 and the two disassembling plate wedge blocks 26. Fig.13 As shown, at this time, the front of the installed electric energy meter body 1 (i.e., the front side of the disassembly and assembly telescopic plate 13) is blocked by two disassembly and assembly plate limiting wedges 27 on the disassembly and assembly plug rod 5, so the electric energy meter body 1 will not be able to move forward, thereby realizing the rapid installation of the electric energy meter body 1;

[0057] When the electric energy meter body 1 needs to be disassembled, the disassembly plug rod 5 can be rotated 90° to separate the disassembly plate wedge block 26 from the disassembly plate limit wedge block 27, and the two plug rod wedge blocks 19 are rotated to the left and right positions. At this time, there is no obstruction in front of the disassembly plug rod 5, and it can be popped forward under the elastic force of the plug rod spring 22, so that the two plug rod wedge blocks 19 are moved out of the long hole of the bracket, thereby realizing the rapid disassembly of the electric energy meter.

[0058] Embodiment 6, based on embodiment 5, as shown in the attached Figure 8-Figure 13 As shown, the quick disassembly assembly 6 also includes an insertion rod spring ring groove 28, an insertion rod spring swivel 29, an insertion rod spring 30, a swivel connecting rod 31, and a connecting rod sliding groove 32;

[0059] A plug rod spring ring groove 28 is provided on the inner side surface of the disassembly hole 4, a plug rod spring swivel 29 is rotatably installed inside the plug rod spring ring groove 28, a plug rod spring 30 connected to the outer side surface of the plug rod spring swivel 29 is installed inside the plug rod spring ring groove 28, two symmetrically positioned swivel connecting rods 31 are fixedly installed on the inner side surface of the plug rod spring swivel 29, and connecting rod sliding grooves 32 are provided on the left and right sides of the outer side surface of the disassembly plug rod 5, and each of the swivel connecting rods 31 is slidably installed in one of the connecting rod sliding grooves 32;

[0060] In combination with Example 5, when this embodiment is in use, when the disassembly and assembly rod 5 is rotated 90°, the disassembly and assembly rod 5 can drive the two swivel connecting rods 31 to rotate 90°, thereby driving the rod spring swivel 29 to rotate 90 degrees, and at the same time driving the rod spring 30 to rotate and store force, and then the disassembly and assembly rod 5 can be inserted into the long hole of the bracket (the connecting rod groove 32 and the swivel connecting rod 31 slide relatively with each other during insertion). After insertion, the disassembly and assembly rod 5 can be reversed 90° and reset under the elastic force of the rod spring 30, thereby realizing the installation of the electric energy meter body 1. Similarly, during disassembly, the disassembly and assembly rod 5 is rotated 90° to drive the rod spring 30 to store force. After the disassembly and assembly rod 5 is pulled out forward, the rod spring 30 drives the disassembly and assembly rod 5 to reverse 90° and reset.

[0061] Embodiment 7, based on embodiment 1, as shown in the attached Figure 1 , Figure 3 As shown, guide grooves 34 are provided on both sides of the terminal board 7, and guide plates 35 that are plugged into the guide grooves 34 are fixedly installed on both ends of the terminal quick-release plate 10, so as to provide a guiding effect when installing the terminal quick-release plate 10, so that when the terminal quick-release plate 10 is inserted into the guide groove 34 through the guide plate 35, the terminal disassembly and assembly components 11 on the terminal quick-release plate 10 can correspond to the positions of multiple terminal blocks 9.

[0062] Embodiment 8, based on embodiment 1, as shown in the attached Figure 6-Figure 7 As shown, the bottom of the terminal 9 is open for inserting the wire, and two front-to-back symmetrical wire pressing pieces 36 are fixedly installed inside the terminal 9. Tooth marks are provided on the opposite surfaces of the two wire pressing pieces 36 to increase the friction and clamping force between the two and the wire, wherein the top of the wire pressing piece 36 located on the front side is separated from the inner wall of the terminal 9. When the wire is inserted, the wire can squeeze the wire pressing piece 36 located on the front side forward, so that the wire can be smoothly inserted between the two wire pressing pieces 36.

The wire pressing bolt 45 inside the sub 9, one end of which passes through the wire pressing through hole 44 and is fixedly installed with a wire pressing insulating block 46 that abuts against the wire pressing piece 36. When the wire pressing bolt 45 is rotated, it can move back and forth inside the wire pressing screw hole 43, so that the wire pressing insulating block 46 squeezes the wire pressing piece 36 on the front side to clamp and fix the wire. When one of the terminal blocks 9 needs to be removed, the corresponding wire pressing bolt 45 can be screwed out of the wire pressing through hole 44 on the terminal block 9, and the terminal 9 can be ejected by the elastic force of the power spring 39.

[0066] Embodiment 10, based on embodiment 9, as shown in the attached Figure 6As shown, a quick-release plate screw hole 47 is provided on the front side of the terminal quick-release plate 10 facing the front side of the terminal board 7, and a quick-release plate bolt 48 is installed on the inner thread of the quick-release plate screw hole. The terminal quick-release plate 10 can be quickly fixed by the quick-release plate bolt 48, and then multiple wire-pressing bolts 45 can squeeze the wire-pressing sheet 36 to fix the wire. To remove a single terminal 9, the corresponding wire-pressing bolt 45 still needs to be loosened. However, when all of them need to be disassembled, it is only necessary to screw the quick-release plate bolt 48 out of the quick-release plate screw hole 47 on the front side of the terminal board 7. Removing the terminal quick-release plate 10 can drive multiple wire-pressing bolts 45 to be taken out from multiple wire-pressing through holes 44, thereby contacting and fixing the terminal 9. At this time, multiple terminal 9 can be ejected under the elastic force of the power connection spring 39, thereby realizing the quick disassembly of multiple terminal 9, and there is no need to loosen the screws one by one to disassemble the wires like when replacing the existing electric energy meter.
