The number of movable blocks 201 is the same as the number of first connecting rings 203. A movable sleeve 202 is rotatably arranged inside each first connecting ring 203, and a first movable straight groove 205, a movable spiral groove 206 and a second movable straight groove 207 are formed on the movable sleeve 202. The first movable straight groove 205 is connected to the movable spiral groove 206 and the second movable straight groove 207.

[0039] The moving block 201 is fixedly connected to one end of the second connecting slide bar 204, and the other end of the second connecting slide bar 204 is slidably arranged inside the corresponding first moving straight groove 205. The moving sleeve 202 is also provided with a first positioning clamping plate 210 and a second positioning clamping plate 211.

[0040] A positioning plate 218 is also provided at the bottom of several moving blocks 201, and a connecting rod is provided between the positioning plate 218 and the corresponding moving block 201. The positioning plate 218 is provided with a corresponding number of positioning slots 220 corresponding to the positions of the first positioning clamping plate 210 and the second positioning clamping plate 211, and two positioning clamping blocks 219 are provided inside each positioning slot 220.

[0041] The first positioning clamping plate 210 is fixedly connected to the inner wall of the movable sleeve 202 , and a plurality of second springs 212 are arranged between the second positioning clamping plate 211 and the inner wall of the movable sleeve 202 .

[0042] A connecting bar 112 is fixedly installed inside the movable guide rail 1 . A plurality of first tooth openings 117 are arranged at the lower end of the connecting bar 112 , and a plurality of second tooth openings 118 are arranged at the upper end of the connecting bar 112 .

[0043] A movable push plate 102 is fixedly arranged on the electric energy meter 101, a positioning block 103 is also arranged on the rear end surface of the electric energy meter 101, a plurality of first springs 109 are arranged between the positioning block 103 and the electric energy meter 101, a plurality of wiring holes 110 are also opened at the bottom of the front end of the electric energy meter 101, a plurality of connecting gears 115 are arranged on the rear end surface of the electric energy meter 101, and the number of the connecting gears 115 is the same as the number of the wiring holes 110.

[0044] The connecting gear 115 is fixedly sleeved on the first connecting slide rod 114 . One end of the first connecting slide rod 114 is slidably disposed inside a connecting slide groove 119 . The connecting slide groove 119 is provided on the movable guide rail 1 .

[0045] The other end of the first connecting slide rod 114 is movably sleeved with a fixing bolt 113, which is rotatably set inside the electric energy meter 101, and a threaded connection is formed between the fixing bolt 113 and the inner wall of the electric energy meter 101. An extrusion plate 120 is also provided at the end of the fixing bolt 113 away from the connecting gear 115, and a connecting spring 116 is provided between the extrusion plate 120 and the fixing bolt 113.

[0046] In this embodiment: See Figure 1 It can be seen that since corresponding fixing holes are provided on the movable guide rail 1, before the user installs the electric energy meter 101, he only needs to fix the movable guide rail 1 on the corresponding wall through the corresponding positioning bolts. At the same time, since a first slide groove 104 is provided on the movable guide rail 1 and a corresponding slider is also provided on the electric energy meter 101, when the user installs the electric energy meter 101, he only needs to install the electric energy meter 101 inside the first slide groove 104 and manually push the electric energy meter 101 to allow the electric energy meter 101 to perform a corresponding sliding effect on the movable guide rail 1.

[0047] See also Figure 8 and Fig. 9 It can be seen that, since a positioning block 103 is also provided on the rear end surface of the electric energy meter 101, and a plurality of first springs 109 are provided between the positioning block 103 and the electric energy meter 101, when the electric energy meter 101 slides inside the movable guide rail 1, the positioning block 103 will be squeezed by the inner wall of the first slide groove 104 and temporarily received inside the electric energy meter 101;

[0048] Since a positioning hole 105 is provided on the moving route of the first slide groove 104, the electric energy meter 101 will move to the position of the positioning hole 105 after sliding a certain distance, and since the positioning hole 105 is connected to the first slide groove 104, the positioning block 103 squeezed by the inner wall of the first slide groove 104 will slide to the position of the positioning hole 105. The positioning block 103 will be clamped in the positioning hole 105 under the action of the reset elastic force of the first spring 109, so as to effectively complete the positioning effect of the electric energy meter 101.

[0049] On the one hand, since a movable push plate 102 is also provided on the electric energy meter 101, and a wiring assembly 2 is also provided on the moving guide rail 1, and the first movable plate 208 and the second movable plate 209 in the wiring assembly 2 are respectively slidably provided inside the third slide groove 107 and the second slide groove 106, when the electric energy meter 101 moves inside the moving guide rail 1, the movable push plate 102 will move synchronously, and since the wiring assembly 2 is provided on the moving track of the movable push plate 102, when the movable push plate 102 moves to the position of the first movable plate 208 and the second movable plate 209, it will synchronously drive the first movable plate 208 and the second movable plate 209 to move accordingly.

[0050] On the other hand, since the first movable plate 208 and the second movable plate 209 slide in the third slide groove 107 and the second slide groove 106 respectively, the third slide groove 107 is divided into a first movable station, a second movable station and a third movable station, and the second slide groove 106 is also divided into a first movable station and a second movable station, and the first movable station of the second slide groove 106 and the first movable station of the third slide groove 107 are opened in parallel, and the height of the second movable station of the third slide groove 107 is further increased on the basis of the first station, which makes it possible for the first movable plate 208 and the second movable plate 209 to move a certain distance following the moving push plate 102, and the first movable plate 208 will slide from the first movable station of the third slide groove 107 into the second movable station;

[0051] When the first moving plate 208 gradually enters the second moving station of the third sliding groove 107, the first connecting rings 203 fixedly arranged on the first moving plate 208 will also drive the corresponding moving sleeves 202 to synchronously follow the first moving plate 208 to complete the corresponding upward movement effect;

[0052] Since the first moving straight groove 205, the moving spiral groove 206 and the second moving straight groove 207 are also provided on the moving sleeve 202, and the first moving straight groove 205 and the moving spiral groove 206 are connected, the moving spiral groove 206 and the second moving straight groove 207 are connected, and one end of the second connecting slide bar 204 is slidably arranged in the first moving straight groove 205, and the other end of the second connecting slide bar 204 is fixedly arranged on the corresponding moving block 201, it should be noted that even if the first moving plate 208 slides from the first moving station of the third slide groove 107 into the second moving station, the second moving plate 209 is still in the first moving station of the second slide groove 106. The movable sleeve 202 slides inside the workstation, so when several first connecting rings 203 drive the corresponding movable sleeves 202 to synchronously follow the first movable plate 208 to complete the corresponding upward movement, the second connecting slide bar 204 will gradually slide from the first movable straight groove 205 into the movable spiral groove 206, and this sliding will also cause the corresponding movable sleeve 202 to rotate accordingly. It should be noted that the movable sleeve 202 will only rotate inside the first connecting ring 203 and will not separate from the first connecting ring 203. Therefore, even if the movable sleeve 202 rotates, it will not affect the first connecting ring 203 driving the movable sleeve 202 to move upward accordingly;

[0053] It should be noted that the number of movable blocks 201, movable sleeves 202 and first connecting rings 203 is set according to the number of wiring holes 110 opened on the power meter 101. Users can also adjust the number of movable blocks 201, movable sleeves 202 and first connecting rings 203 according to their own needs and actual conditions.

[0054] Since each movable sleeve 202 is provided with a first positioning clamping plate 210 and a second positioning clamping plate 211, the first positioning clamping plate 210 is fixedly arranged on the inner wall of the movable sleeve 202, and the second positioning clamping plate 211 is softly connected to the movable sleeve 202 through a plurality of second springs 212. It should be noted that since the second positioning clamping plate 211 is squeezed by the elastic force of the second spring 212 in the initial state, the second positioning clamping plate 211 and the first positioning clamping plate 210 are in a clamping state in the initial state, so the user can During positioning and installation, it is only necessary to manually bend the second positioning clamp 211 to allow the wire to be connected to complete the corresponding positioning and installation. This arrangement allows the wire fixedly clamped by the second positioning clamp 211 and the first positioning clamp 210 to rotate accordingly with the movable sleeve 202, so that the loose wire at the front end of the wire can be gathered again under the action of this rotation, or the wire with a certain bend at the front end of the wire can become vertical again under the action of this rotation forward movement, so that when it is subsequently connected to the wiring hole 110, the connection effect can be quickly completed.

[0055] It should be noted that after the wires are fixed via the first positioning clamp 210 and the second positioning clamp 211, the ends of the several wires are still inside the several positioning slots 220 opened in the positioning plate 218. Since two positioning clamps 219 are arranged inside each positioning slot 220, and each positioning clamp 219 forms a fixed connection with the output end of the embedded cylinder arranged inside the positioning plate 218, when the wires are fixed via the first positioning clamp 210 and the second positioning clamp 211, the user can also start the corresponding embedded cylinder to allow the corresponding positioning clamp 219 to complete the fixing effect on the ends of the wires, so that when the second movable plate 209 is moved up later, the wires can be effectively driven into the corresponding wiring hole 110.

[0056] When the first moving plate 208 slides from the first moving station of the third sliding groove 107 into the second moving station, the second connecting slide rod 204 also slides from the moving spiral groove 206 into the second moving straight groove 207, and the moving sleeve 202 also stops rotating.

[0057] On the one hand, since a plurality of connecting gears 115 are provided on the rear end surface of the electric energy meter 101, and each connecting gear 115 is fixedly sleeved on the corresponding first connecting slide bar 114, and one end of the first connecting slide bar 114 is slidably arranged inside the connecting slide groove 119, and a fixing bolt 113 slidably arranged inside the electric energy meter 101 is sleeved on the other end of the first connecting slide bar 114, and a threaded connection is formed between the fixing bolt 113 and the first connecting slide bar 114;

[0058] On the other hand, since a connecting strip 112 is further provided on the first slide slot 104, and a plurality of first tooth openings 117 are provided on the lower end surface of the connecting strip 112, and a plurality of second tooth openings 118 are provided on the lower end surface of the connecting strip 112;

[0059] This means that when the energy meter 101 moves a certain distance inside the first slide slot 104, the connecting gear 115 sleeved on the first connecting slide bar 114 will mesh with the plurality of first tooth openings 117, thereby driving the first connecting slide bar 114 to rotate accordingly.

[0060] Since the first connecting slide bar 114 is also movably sleeved with a fixing bolt 113, and a threaded connection is formed between the fixing bolt 113 and the inner wall of the electric energy meter 101, when the first connecting slide bar 114 rotates, the fixing bolt 113 will perform a corresponding movement effect inside the electric energy meter 101, and perform a corresponding movement on the first connecting slide bar 114, and this movement is close to the connecting gear 115.

[0061] It should be noted that when the fixing bolt 113 is in the initial position, the extrusion plate 120 arranged at the end away from the connecting gear 115 is in contact with the surface of one side of the wiring hole 110. This arrangement, on the one hand, forms corresponding protection for the interior of the wiring hole 110 to prevent small debris from accidentally entering the interior of the wiring hole 110, thereby causing subsequent wiring difficulties. On the other hand, when the subsequent wire enters the interior of the wiring hole 110, the wiring hole 110 is already in an open state through the above movement, which also facilitates the connection between the wire and the wiring hole 110.

[0062] As the electric energy meter 101 continues to move, several connecting gears 115 will mesh with several groups of second teeth 118. Since several groups of second teeth 118 are arranged on the upper end surface of the connecting strip 112, after the connecting gear 115 meshes with the second teeth 118, the connecting gear 115 will rotate in the opposite direction. The reversal of the connecting gear 115 will not only drive the first connecting slide bar 114 to reverse synchronously, but also the fixing bolt 113 sleeved on the first connecting slide bar 114 will move closer to the wiring hole 110 again. After several connecting gears 115 have completed the meshing rotation with the second teeth 118, several fixing bolts 113 will move to the initial position again and complete the extrusion connection effect on the wire. It should be noted that the wire has completed the docking with the wiring hole 110 at this time.

[0063] It should be noted that since a connecting spring 116 is provided between the extrusion plate 120 and the fixing bolt 113, when the wire enters the wiring hole 110, the extrusion plate 120 cannot move to fit the inner wall of the wiring hole 110. The elastic force of the connecting spring 116 can also effectively allow the extrusion plate 120 to adaptively adjust the distance between it and the wire, which not only ensures the fixed connection of the wire, but also prevents the resetting of the fixing bolt 113 from getting stuck.

[0064] It should be noted that the extrusion plate 120 is an electrical connector, but the fixing bolt 113 is made of an insulating material. This setting is to prevent leakage of electricity after the extrusion plate 120 completes the extrusion and fixation of the wire. In addition, since the fixing bolt 113 is arranged inside the electric energy meter 101, it also prevents electricity theft to a certain extent.

[0065] Through the above-mentioned arrangement, not only the positioning and installation effect of the electric energy meter 101 is effectively completed, but also during the movement of the electric energy meter 101, through the arrangement of the wiring assembly 2, the electric energy meter 101 can drive the first movable plate 208 and the second movable plate 209 to move by the moving push plate 102 during the movement, and the first connecting ring 203 and the movable sleeve 202 arranged on the first movable plate 208 can also synchronously complete the corresponding movement, and then the wire to be connected arranged inside the movable sleeve 202 can synchronously follow the first movable plate 208 to complete the corresponding movement, and before the electric energy meter 101 is positioned, the electrical connection between multiple groups of wires and the electric energy meter 101 is effectively completed. Compared with the prior art, this arrangement also avoids the need for manual secondary wiring after the electric energy meter 101 is installed, thereby greatly saving the overall installation efficiency of the electric energy meter 101.

[0066] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Figure 1-Figure 2 as well as Figure 5-Figure 7 As shown, a connection groove 217 is formed on the bottom surface of each second positioning clamping plate 211 , and a second connection ring 215 is slidably disposed inside the connection groove 217 . A plurality of second connection rings 215 are connected via positioning rods 216 .

[0067] A second extrusion block 213 is fixedly disposed on the inner wall of the second positioning clamping plate 211 . A communication groove 214 is also formed on the second positioning clamping plate 211 . The communication groove 214 is formed below the second extrusion block 213 .

[0068] A fourth slide groove 111 is provided between the second slide groove 106 and the third slide groove 107 , and a first extrusion block 108 is slidably provided inside the fourth slide groove 111 . A first slide groove 104 and a positioning hole 105 are provided inside the movable guide rail 1 , and the first slide groove 104 and the positioning hole 105 are connected to each other.

[0069] In this embodiment: since a third moving station is also provided inside the third slide groove 107, and the third moving station descends on the basis of the second moving station, when the first moving plate 208 slides from the second moving station of the third slide groove 107 into the third moving station, the first moving plate 208 will drive the plurality of moving sleeves 202 and the first connecting ring 203 to move downward synchronously accordingly;

[0070] See also Figure 1 and Figure 2 It can be seen that since a fourth chute 111 is provided between the third chute 107 and the second chute 106, a first extrusion block 108 is provided inside the fourth chute 111;

[0071] See also Figure 5It can be seen that, since the second positioning clamping plate 211 is further provided with a second extrusion block 213 at the inner wall thereof, and a connecting groove 214 is further provided below the second extrusion block 213, it should be noted that: Figure 5 The moving sleeve 202 and the moving block 201 are in an unseparated state. When the moving sleeve 202 and the moving block 201 are separated, the connecting groove 214 will move out of the moving block 201.

[0072] Therefore, when the first moving plate 208 slides from the second moving station of the third sliding groove 107 to the third moving station, the first extrusion block 108 will enter between the second positioning clamping plate 211 and the first positioning clamping plate 210 through the connecting groove 214. Since a fixed connection is formed between the first positioning clamping plate 210 and the moving sleeve 202, after the first extrusion block 108 contacts the first positioning clamping plate 210, the first positioning clamping plate 210 will drive the first extrusion block 108 to move correspondingly inside the fourth sliding groove 111.

[0073] Since the length of the first extrusion block 108 is set to be longer, when the second positioning clamp plate 211 moves downward following the movable sleeve 202, the first extrusion block 108 will squeeze the extrusion slope provided on the second extrusion block 213. After the second extrusion block 213 is squeezed, since the second extrusion block 213 is fixedly set on the second positioning clamp plate 211, the second positioning clamp plate 211 will move away from the first positioning clamp plate 210 under the squeezing action of the first extrusion block 108, so that the wire set inside the movable sleeve 202 can be smoothly separated from the movable sleeve 202.

[0074] On the one hand, since the ends of the plurality of wires are fixed by the positioning clamps 219, and the positioning plates 218 are also fixedly disposed on the plurality of moving blocks 201;

[0075] On the other hand, since a second moving station is also provided inside the second slide groove 106, and the second moving station is raised on the basis of the first moving station, when the second moving plate 209 slides from the first moving station of the second slide groove 106 into the second moving station, the second moving plate 209 will drive the plurality of moving blocks 201 and the positioning plate 218 to complete the corresponding upward movement;

[0076] Since the upward movement of the second movable plate 209 and the downward movement of the first movable plate 208 are at the same time, when the wires are released from the restriction, the second movable plate 209 can be moved upward to smoothly transport several wires to the corresponding wiring holes 110. At this time, the connecting gear 115 also starts to engage with the second tooth mouth 118, so that the fixing bolt 113 can complete the squeezing and fixing effect of the wires. Therefore, in this way, the electrical connection effect between the wires and the electric energy meter 101 can be effectively completed.

[0077] It should be noted that when the first movable plate 208 is in the second movable position of the third slide groove 107, the second connecting slide bar 204 is in the second movable straight groove 207 opened by the movable sleeve 202, and when the first movable plate 208 slides from the second movable position of the third slide groove 107 into the third movable position, the second connecting slide bar 204 is still in the second movable straight groove 207 opened by the movable sleeve 202. This arrangement is to avoid the first movable plate 208 being reset. If the reset distance is too large, it is likely to cause the movable sleeve 202 to reverse. When the movable sleeve 202 reverses, if the wire has not yet separated from the second positioning clamp 211 and the first positioning clamp 210, the wire will flip over, thereby affecting the electrical connection with the electric energy meter 101.

[0078] It should be noted that, since a connecting groove 217 is provided on the bottom surface of the second positioning clamp 211, and a second connecting ring 215 is rotatably arranged inside the connecting groove 217, and the second connecting ring 215 will only rotate inside the connecting groove 217, but will not be separated from the connecting groove 217, and at the same time, several second connecting rings 215 are connected by a positioning rod 216, which makes it possible for several second positioning clamps 211 to move accordingly when one of the second positioning clamps 211 moves. Therefore, when a second positioning clamp 211 is squeezed and moved by the first squeezing block 108, thereby releasing the restriction on the wire, several second positioning clamps 211 will release the restriction on the corresponding wire, so that the wire that has been fixed can be smoothly separated from the wiring assembly 2.

[0079] Through the above-mentioned arrangement, the first movable plate 208 can be reset to a certain distance while the electric energy meter 101 continues to move. The reset of the first movable plate 208 will not only drive the second positioning clamp 211 to reset accordingly, but the second positioning clamp 211 will also release the restriction on the wire during the reset process. At the same time, due to the arrangement of the second connecting ring 215 and the positioning rod 216, one of the second positioning clamps 211 will release the restriction on the wire, and several second positioning clamps 211 will release the restriction on the corresponding wire, so that the wire that has been fixed can be smoothly separated from the wiring assembly 2.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
