The quick mounting mechanism can guide the electric meter during installation. The wire clamping mechanism can clamp the wire when the bearing seat slides, and the wire clamping rod can clamp the wire and move downward, so that the wire avoids the electric meter and prevents the wire from being bent. After the electric meter moves to the installation position, the wire clamping rod can automatically clamp the wire and lift it, so that the wire is inserted into the wiring position of the electric meter, and quick wiring is realized. When the staff manually wires, the small internal space of the electric energy metering box does not cause inconvenient wiring.

Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an electricity metering box. Background Technology

[0002] Electricity metering boxes are an important component of the power system, mainly used for accurate metering and monitoring of electrical energy. With the development of technology, the functions and performance of electricity metering boxes are constantly improving, providing strong support for power management and energy conservation.

[0003] When installing electricity meters in an electricity metering box, the narrow gap between adjacent meters makes it difficult to operate the wires and connect them. The limited space and obstructed view make it necessary to use both hands to connect the wires, further hindering the connection and making it easy to connect the phase wire and the neutral wire incorrectly. The wires are often bent and squeezed in the confined space, damaging the internal structure of the wire insulation layer, which is especially prone to cracking in low-temperature environments. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an electricity metering box.

[0005] The technical implementation of the present invention is as follows: an electricity metering box includes an electricity metering box and several fixed frames installed inside the electricity metering box. The fixed frames are provided with quick-installation mechanisms. The quick-installation mechanisms include a support seat that is elastically slidably connected to the fixed frame in the horizontal direction and a guide rail fixed to the fixed frame. A sliding frame is elastically slidably connected to the guide rail in the vertical direction. A wire clamping mechanism is provided on the sliding frame. The wire clamping mechanism includes a pair of wire clamping rods that are slidably connected to the sliding frame in the horizontal direction. A compression spring is provided between the pair of wire clamping rods. A U-shaped frame is fixed to the support seat. A pair of driving blocks are slidably connected to the U-shaped frame in the vertical direction. A wedge-shaped plate that is slidably embedded in the driving block is fixed to the wire clamping rod.

[0006] In a preferred embodiment of the present invention, the wire clamping mechanism further includes a pair of first tripods fixed to the support base, a pair of first convex shafts cooperating with the first tripods fixed to the sliding frame, a pair of guide posts fixed to the support base, and spring pieces fixed to the guide posts.

[0007] In a preferred embodiment of the present invention, the wire clamping mechanism further includes a limiting block that is slidably connected in the horizontal direction within the guide rail, and the sliding frame cooperates with the limiting block.

[0008] In a preferred embodiment of the present invention, a pair of locking plates are elastically slidably connected in the vertical direction inside the fixing frame, and the locking plates cooperate with the bearing seat.

[0009] In a preferred embodiment of the present invention, an unlocking plate is elastically slidably connected in the horizontal direction inside the guide rail, the unlocking plate is connected to the limiting block, and the unlocking plate cooperates with the first tripod.

[0010] In a preferred embodiment of the present invention, the fixing frame is provided with a quick-release mechanism, the quick-release mechanism including a rectangular frame that is slidably connected to the fixing frame in the horizontal direction, two sets of unlocking blocks are fixedly connected to the rectangular frame, and a pair of second convex shafts that cooperate with the unlocking blocks are fixedly connected to the locking plate.

[0011] In a preferred embodiment of the present invention, the quick-release mechanism further includes a handle hinged to the fixed frame, and a pair of connecting rods are hinged between the handle and the rectangular frame.

[0012] In a preferred embodiment of the present invention, a pair of damping plates that rub against the bearing seat are embedded and fixedly connected within the fixing frame.

[0013] In a preferred embodiment of the present invention, the damping plate rubs against the support seat, which enables the support seat to slowly and elastically release and slide, preventing the meter on the support seat from being quickly pushed out and falling.

[0014] In a preferred embodiment of the present invention, a second tripod that cooperates with the first convex shaft is fixedly connected to one side of the first tripod.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting up a quick-installation mechanism, can guide the electricity meter during installation. By setting up a wire clamping mechanism, when the support seat slides, the wire clamping rod can clamp the wire and move the clamping rod downward to keep the wire away from the electricity meter and prevent the wire from bending. After the electricity meter moves to the installation position, the wire clamping rod can automatically clamp the wire and lift it up, so that the wire can be inserted into the wiring position of the electricity meter, realizing quick wiring and avoiding the inconvenience of wiring due to the small internal space of the electricity metering box when the staff manually connects the wire.

[0016] 2. By setting up a quick-release mechanism, when the electricity meter is being inspected or replaced, the support seat can be elastically released and slid out of the meter by pulling the handle. By setting up a damping plate, friction can be applied to the support seat, causing the support seat to slide slowly and preventing the electricity meter from being pushed out and falling off and being damaged.

[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] Example 1: An electricity metering box, such as Figures 1-7As shown, the device includes an electricity metering box 1 and several mounting brackets 201 installed inside the electricity metering box 1. The number of mounting brackets 201 can be adjusted according to the number of electricity meters 100 installed. Each mounting bracket 201 is equipped with a quick-installation mechanism, which includes a support seat 202 that is elastically slidably connected to the mounting bracket 201 in the horizontal direction, and a guide rail 203 fixed to the lower front side of the mounting bracket 201. A sliding frame 204 is elastically slidably connected to the outer wall of the guide rail 203 in the vertical direction. The sliding frame 204 is equipped with a wire clamping mechanism. The guide rail 203 and the sliding frame 204 are connected to the support seat 202. 04 corresponds to one wire with the wire clamping mechanism, and the number of guide rail 203, sliding frame 204 and wire clamping mechanism can be adjusted according to the number of wires connected to the meter 100. The wire clamping mechanism includes a pair of wire clamping rods 205 that are slidably connected in the horizontal direction in the sliding frame 204. A compression spring is provided between the pair of wire clamping rods 205. A U-shaped frame 206 is fixedly connected to the bottom of the bearing seat 202. A pair of driving blocks 207 are slidably connected in the vertical direction in the U-shaped frame 206. A wedge plate 208 that is slidably embedded in the driving block 207 is fixedly connected to the opposite sides of the two wire clamping rods 205.

[0021] like Figure 8 and Figure 9 As shown, the clamping mechanism also includes a pair of first triangular frames 301 fixed to the bottom of the support 202. A pair of first convex shafts 302 that cooperate with the first triangular frames 301 are fixed to the left and right sides of the sliding frame 204. A pair of guide posts 303 are fixed to the support 202. A spring piece 304 is fixed to the outer wall of the guide post 303. A pair of slots for inserting the guide posts 303 are reserved on the rear side of the meter 100 (the slots are prior art and are not shown in the figure, so they will not be described in detail here).

[0022] like Figure 8 As shown, the wire clamping mechanism also includes a limiting block 401 that is slidably connected in the guide rail 203 in the horizontal direction. The sliding frame 204 cooperates with the limiting block 401, and can limit the sliding frame 204 when the limiting block 401 abuts against the top of the sliding frame 204.

[0023] like Figure 9 As shown, a pair of locking plates 501 are elastically slidably connected in the vertical direction inside the fixing frame 201. The locking plates 501 cooperate with the bearing seat 202. The locking plates 501 can limit the bearing seat 202 by fitting against the front side of the bearing seat 202.

[0024] like Figure 10 As shown, an unlocking plate 601 is elastically slidably connected in the horizontal direction inside the guide rail 203. The unlocking plate 601 is fixedly connected to the limiting block 401. The unlocking plate 601 cooperates with the first tripod 301. When the first tripod 301 presses against the unlocking plate 601, the limiting block 401 can no longer limit the sliding frame 204.

[0025] Initially, the compression spring between the two clamping rods 205 is in the released state, and the gap between the two clamping rods 205 is just enough to insert the wire. First, peel off the insulation layer of the wire and place the wire between the two clamping rods 205 with the conductor facing upwards. The two clamping rods 205 lightly clamp the wire, making it easy to adjust its position. Align the cut surface of the wire's insulation layer with the top of the two clamping rods 205, thus completing the initial fixation of the wire. Then, place the meter 100 on the support base 202 and push it backward, causing the two guide posts 303 to enter a pair of slots on the rear side of the meter 100. The spring piece 304, after being pressed by the slots of the meter 100, elastically releases and locks into the slots, limiting the meter 100 and fixing it on the support base 202. 2. Continue pushing the meter 100. The meter 100 drives the support seat 202 to elastically retract and slide backward along the fixed frame 201. The support seat 202 drives the U-shaped frame 206 and the two first triangular frames 301 to move backward. The U-shaped frame 206 drives the two driving blocks 207 inside it to move backward. The driving blocks 207 press against the inclined surface of the adjacent wedge plate 208, causing the two wire clamping rods 205 to slide closer to each other. The compression spring is compressed, and the two wire clamping rods 205 clamp the wire to prevent the wire from moving arbitrarily. At the same time, the first triangular frame 301 presses against the adjacent first convex shaft 302, causing the sliding frame 204 to elastically retract and slide downward. The sliding frame 204 drives the two wire clamping rods 205 to move downward. The two wire clamping rods 205 clamp the wire and lower it, so that the wire avoids the meter 1. 00, to prevent the wire from bending, the clamping rod 205 drives the wedge plate 208 on it to descend. The wedge plate 208 drives the corresponding driving block 207 to slide down along the U-shaped frame 206. Then the driving block 207 contacts the vertical surface of the adjacent wedge plate 208 and continues to slide along the U-shaped frame 206, so that the two clamping rods 205 keep clamping the wire. After the sliding frame 204 continues to slide, it contacts and presses against the inclined surface of the limiting block 401. The limiting block 401 is forced to slide backward and drives the unlocking plate 601 to elastically contract and slide backward until the sliding frame 204 passes the limiting block 401. The unlocking plate 601 elastically releases the sliding and drives the limiting block 401 to slide and reset. The limiting block 401 abuts against the top of the sliding frame 204 to limit the sliding frame 204, so that the sliding frame 204 04. Maintaining the elastic contraction state, the two clamping rods 205 keep the wire clamped below the meter 100. The first tripod 301 continues to move and disengage from the first convex shaft 302. Subsequently, the first tripod 301 contacts and presses against the unlocking plate 601. The unlocking plate 601 is subjected to force and elastically contracts and slides backward, driving the limiting block 401 to slide backward. After sliding, the limiting block 401 disengages from the sliding frame 204. At the same time, the bearing seat 202 contacts and presses against the inclined surfaces of the two locking plates 501. The two locking plates 501 are subjected to force and elastically contract and slide away from each other. The bearing seat 202 continues to slide past the two locking plates 501. At this time, the meter 100 moves to the installation position, and the wiring position of the meter 100 is directly above the wire. The sliding frame 204 disengages from the restriction and elastically releases its sliding motion.This causes the two clamping rods 205 to move upwards, clamping the wire and inserting it into the wiring position of the meter 100. Simultaneously, the clamping rods 205 drive the corresponding wedge plate 208 to rise and reset. The wedge plate 208 then drives the corresponding driving block 207 to slide upwards along the U-shaped frame 206 and reset. The two locking plates 501 release their restraints and slide back to their original positions, fitting against the front of the support seat 202, thus limiting the support seat 202 and fixing the meter 100 inside the energy metering box 1. This also secures the wire inside the meter 100. During meter placement, the wire automatically avoids the meter 100, preventing bending and automatically inserting into the wiring position. The wire can then be secured by tightening the bolts on the meter 100 with a screwdriver. This method allows for quick installation of the meter 100 and rapid connection of the wire to the meter, all with one hand.

[0026] Example 2: As Figure 9 As shown, the fixed frame 201 is provided with a quick-release mechanism. The quick-release mechanism includes a rectangular frame 701 that is slidably connected to the outer wall of the fixed frame 201 in the horizontal direction. Two sets of unlocking blocks 702 are fixedly connected to the front side of the rectangular frame 701, with two blocks in each set. A pair of second convex shafts 703 that cooperate with the unlocking blocks 702 are fixedly connected to the locking plate 501.

[0027] like Figure 9 As shown, the quick-release mechanism also includes a handle 801 hinged to the fixed frame 201. A pair of connecting rods 802 are hinged between the handle 801 and the rectangular frame 701. By pulling the handle 801, the two locking plates 501 can be moved away from each other, elastically contracted and slid, and no longer limit the bearing seat 202.

[0028] like Figure 11 As shown, a pair of damping plates 901 are embedded and fixed to the inner wall of the fixing frame 201, which rub against the bottom of the support seat 202. Through the friction between the damping plates 901 and the support seat 202, the support seat 202 can be slowly and elastically released and slid, preventing the meter 100 on the support seat 202 from being quickly pushed out and falling.

[0029] like Figure 12 As shown, a second tripod 1001 that cooperates with the first convex shaft 302 is fixedly connected to one side of the first tripod 301. The second tripod 1001 can cause the two wire clamping rods 205 to clamp and lower the wire by pressing the first convex shaft 302.

[0030] When meter 100 needs maintenance or replacement, the worker uses a screwdriver to loosen the bolts on meter 100, freeing the wires from being fixed to meter 100. Then, the worker pulls handle 801, causing it to rotate downwards. Handle 801, through two connecting rods 802, drives rectangular frame 701 forward. Rectangular frame 701 drives two sets of unlocking blocks 702 forward, pressing the corresponding second convex shaft 703. This causes the two locking plates 501 to move away from each other, elastically contracting and sliding. Both locking plates 501 disengage from the support seat 202, allowing the support seat 202 to move freely. At this point, damping plate 901 applies friction to the support seat 202, causing it to slowly and elastically release and slide. The support seat 202 then drives meter 100... The mechanism moves slowly forward, causing the U-shaped frame 206 and the two first triangular frames 301 to move forward as well. This releases the handle 801, causing the two locking plates 501 to elastically release and slide back to their original positions. The locking plates 501 then move and reset their respective second convex shafts 703. The second convex shafts 703 press against the adjacent unlocking blocks 702, causing the unlocking blocks 702 to slide and reset the rectangular frame 701. The rectangular frame 701, through two connecting rods 802, causes the handle 801 to rotate and reset. The U-shaped frame 206 then moves its two internal driving blocks 207 forward. The first triangular frame 301 moves its second triangular frame 1001 forward, and the second triangular frame 1001 presses against the adjacent first convex shaft 302, causing the sliding frame 204 to elastically contract and slide downwards. The sliding frame 204 then moves the two clamping wires... The clamping rod 205 moves downward, thus keeping the wire away from the meter 100 as much as possible to prevent excessive bending. Simultaneously, the clamping rod 205 causes the wedge plate 208 on it to descend. The wedge plate 208 drives the corresponding driving block 207 to slide downward along the U-shaped frame 206. Then, the sliding frame 204 contacts and presses against the inclined surface of the limiting block 401. The limiting block 401 slides backward under force, causing the unlocking plate 601 to elastically contract backward until the sliding frame 204 passes the limiting block 401. The unlocking plate 601 then elastically releases its sliding motion, causing the limiting block 401 to slide back to its original position. The limiting block 401 and the top of the sliding frame 204 abut against each other again, limiting the sliding frame 204 and keeping it in an elastically contracted state. This ensures that the two clamping rods 205 keep the wire clamped to the meter 100. Below 0, the second tripod 1001 continues to move and disengage from the first convex shaft 302, and the bearing seat 202 continues to elastically release and slide back to its original position. This causes the U-shaped frame 206, the first tripod 301, and the second tripod 1001 to move and reset. The driving block 207 passes over the corresponding wedge plate 208, and the compressed spring releases, causing the wire clamping rod 205 to elastically release and slide back to its original position. The wire clamping rod 205 causes the wedge plate 208 on it to move and reset. The wire clamping rod 205 no longer clamps the wire, making it easier to organize the wire later. At this time, the meter 100 is removed, and the worker pushes the unlocking plate 601 backward, causing the limit block 401 to slide and disengage from the sliding frame 204. The sliding frame 204 releases its restriction and elastically slides, causing the two wire clamping rods 205 to move upward and reset.The clamping rod 205, via its wedge-shaped plate 208, drives the adjacent driving block 207 to slide upwards and reset along the U-shaped frame 206. This releases the unlocking plate 601, causing it to elastically release and slide, thus resetting the limiting block 401. This completes the quick disassembly of the meter 100. Repeating these steps during subsequent installation of the meter 100 achieves the same effect.

[0031] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
