Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology and relates to an electricity meter that is easy to install and disassemble. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also called an energy meter, kilowatt-hour meter, or watt-hour meter. Because electricity meters require periodic calibration, fault repair, or upgrades, there is a need for an electricity meter that is easy to install and remove to reduce installation and removal time and significantly shorten power outage time.

[0003] A power meter that is easy to install is disclosed in Chinese patent CN222896203U. A pair of connectors are provided at the top and bottom of the power meter body. The connectors include a base that is fixedly connected to the surface of the power meter body. A telescopic rod is threaded onto the base. A circular plate is provided at the end of the telescopic rod away from the base. A connecting rod is provided at the top of the circular plate. The connecting rod is inserted into the circular groove through a socket and cooperates with the limiting cavity.

[0004] During installation, the movable end of the telescopic rod needs to be moved upwards to insert the connecting rod into the socket, and then the connecting rod needs to be rotated into the limiting cavity. Because the connecting rod is a rectangular horizontal bar, it needs to be rotated to align with the socket during disassembly. However, the circular plate obstructs the socket, making the fit between the connecting rod and the socket less precise and the operation less convenient.

[0005] To address the aforementioned problems, this utility model proposes an energy meter that is easy to install and disassemble. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an energy meter that is easy to install and disassemble.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes an installation plate and a connecting plate, with the electricity meter body fixedly connected to one side of the connecting plate, and fixed plates fixedly connected to the top and bottom of one side of the installation plate, and the connecting plate is movably disposed between the two fixed plates;

[0008] Both ends of the top and bottom surfaces of the connecting plate are fixedly connected to a fixed cylinder. Both ends of the two fixed plates that are close to each other are fixedly connected to a limit cylinder. The limit cylinder and the fixed cylinder correspond one to one. Each fixed cylinder has a sliding rod inside it through a spring. The end of the sliding rod is movably set in the corresponding limit cylinder.

[0009] Each of the slide bars is fixedly connected to a first crossbar and a second crossbar. The first crossbar is slidably connected to the corresponding fixed cylinder, and the second crossbar is slidably set on the corresponding limiting cylinder.

[0010] Furthermore, two locking blocks are symmetrically fixedly connected to one side of the mounting plate, and the two corresponding sides of the connecting plate are provided with locking slots that are adapted to the locking blocks. When the connecting plate moves between the two locking blocks, the locking slots are slidably set on the corresponding locking blocks.

[0011] Furthermore, each of the two fixing plates has a groove on one side at each limiting cylinder, and a rotating block is rotatably arranged inside each groove, and each rotating block can contact the outer surface of the corresponding limiting cylinder.

[0012] Furthermore, each groove is fixedly connected to a rotating shaft, and the end of the rotating block is rotatably sleeved on the corresponding rotating shaft. Each rotating shaft is fitted with a torsion spring at both ends. One end of the torsion spring is fixedly connected to the inner wall of the groove, and the other end of the torsion spring is fixedly connected to one side of the corresponding rotating block.

[0013] Furthermore, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the end of the corresponding slide rod.

[0014] Furthermore, each of the fixed cylinders has two fixing grooves on its side, which are arranged in a circumferential array about the fixed cylinder. The first crossbar is horizontally arranged, and the two ends of the first crossbar are slidably disposed in the two fixing grooves respectively. Both ends of the first crossbar extend to the outside of the fixed cylinder.

[0015] The fixing groove is composed of an inclined groove, a vertical groove, a first sliding groove, and a first horizontal groove from one end to the other. The inclined groove and the first sliding groove are both inclined, and the inclination directions of the inclined groove and the first sliding groove are opposite.

[0016] Each of the limiting cylinders has two limiting grooves, which are arranged in a circular array about the limiting cylinder. The two limiting grooves on the limiting cylinder correspond one-to-one with the two fixing grooves on the corresponding fixing cylinder. The second crossbar is horizontally arranged, and the two ends of the second crossbar are slidably set in the two limiting grooves respectively.

[0017] The limiting groove is composed of a second sliding groove and a second transverse groove. The second sliding groove and the corresponding first sliding groove have the same inclination direction. The second sliding groove passes through the end face of the limiting cylinder.

[0018] Furthermore, positioning plates are fixedly connected to the top and bottom of both sides of the mounting plate, and each positioning plate has a through hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The energy meter, which is easy to install and disassemble, is equipped with a sliding rod. Moving the end of the sliding rod into the corresponding limiting cylinder can fix the connecting plate to one side of the mounting plate, thereby installing the energy meter body. When disassembling, by pushing the first crossbar to slide in the fixing groove, the second crossbar can slide in the limiting groove, which can move the sliding rod out of the limiting cylinder. Then the connecting plate can be directly removed, making the operation simple.

[0021] 2. The energy meter that is easy to install and disassemble is provided with a sloping groove. By moving the first crossbar into the sloping groove, the first crossbar can be positioned on the sloping groove, and the sliding rod can be positioned in the fixed cylinder, which facilitates the disassembly of the connecting plate and achieves the purpose of easy disassembly.

[0022] 3. The energy meter, which is easy to install and disassemble, is equipped with a rotating block. When the connecting plate is moved to one side of the mounting plate, the sliding rod is squeezed by the rotating block, causing the first horizontal rod to move to the bottom of the inclined groove. Under the action of the spring torsional force and elastic force, the first horizontal rod automatically slides through the vertical groove and the first sliding groove into the first horizontal groove, and then automatically slides the second horizontal rod through the second sliding groove into the second horizontal groove. This automatically positions the end of the sliding rod in the limiting cylinder, realizing the installation of the energy meter body and achieving the purpose of facilitating installation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: An energy meter that is easy to install and disassemble includes a mounting plate 1 and a connecting plate 18. The energy meter body 4 is fixedly connected to one side of the connecting plate 18. Fixing plates 3 are fixedly connected to the top and bottom of one side of the mounting plate 1, and the fixing plates 3 are arranged horizontally. The connecting plate 18 is movably disposed between the two fixing plates 3.

[0031] Two locking blocks 2, each with a T-shaped structure, are symmetrically fixed to one side of the mounting plate 1. The connecting plate 18 has slots 19 on its two corresponding sides that mate with the locking blocks 2. When the connecting plate 18 moves between the two locking blocks 2, the slots 19 slide onto the corresponding locking blocks 2. Through the cooperation of the slots 19 and the locking blocks 2, the connecting plate 18 is positioned on one side of the mounting plate 1.

[0032] Positioning plates 21 are fixedly connected to the top and bottom of both sides of the mounting plate 1, and each positioning plate 21 has a through hole. The positioning plates 21 can be fixed to the mounting plate 1 by using bolts through the through holes.

[0033] Fixed cylinders 5 are fixedly connected to both ends of the top and bottom surfaces of the connecting plate 18. Limiting cylinders 12 are fixedly connected to both ends of the two adjacent sides of the two fixed plates 3, with each limiting cylinder 12 corresponding to a fixed cylinder 5. A sliding rod 11 is slidably installed inside each fixed cylinder 5 via a spring 7, and the end of the sliding rod 11 is movably installed in the corresponding limiting cylinder 12. The fixed cylinders 5 and limiting cylinders 12 are connected by the sliding rods 11, positioning the connecting plate 18 on one side of the mounting plate 1, thereby installing the energy meter body 4.

[0034] One end of the spring 7 is fixedly connected to the connecting plate 18, and the other end of the spring 7 is fixedly connected to the end of the corresponding slide rod 11. The spring 7 is located inside the fixed cylinder 5.

[0035] Each slide bar 11 has a first crossbar 10 and a second crossbar 15 fixedly connected through it. The first crossbar 10 is slidably connected to the corresponding fixed cylinder 5, and the second crossbar 15 is slidably mounted on the corresponding limiting cylinder 12. When the slide bar 11 moves, it can drive the first crossbar 10 to slide on the fixed cylinder 5, and at the same time drive the second crossbar 15 to slide on the limiting cylinder 12.

[0036] Each fixed cylinder 5 has two fixing slots on its side, arranged in a circular array about the cylinder 5. A first crossbar 10 is horizontally positioned, with its two ends slidably disposed within the two fixing slots. Both ends of the first crossbar 10 extend outside the fixed cylinder 5, facilitating movement by the operator.

[0037] The fixing groove consists of an inclined groove 6, a vertical groove 20, a first sliding groove 8, and a first horizontal groove 9 from one end to the other. Both the inclined groove 6 and the first sliding groove 8 are inclined, and their inclination directions are opposite. The vertical groove 20 is vertically arranged, and the vertical groove 20 and the inclined groove 6 form a hook shape. The inclined groove 6 and the first sliding groove 8 are inclined to different sides of the vertical groove 20.

[0038] Each limiting cylinder 12 has two limiting grooves, which are arranged in a circular array about the limiting cylinder 12. The two limiting grooves on the limiting cylinder 12 correspond one-to-one with the two fixing grooves on the corresponding fixing cylinder 5. The second crossbar 15 is arranged horizontally, and its two ends are slidably set in the two limiting grooves respectively.

[0039] The limiting groove consists of a second sliding groove 13 and a second transverse groove 14. Both the first transverse groove 9 and the second transverse groove 14 are horizontally arranged. The second sliding groove 13 and the corresponding first sliding groove 8 have the same inclination direction, and the second sliding groove 13 passes through the end face of the limiting cylinder 12, allowing the second transverse rod 15 to slide out of the second sliding groove 13.

[0040] Each of the two fixed plates 3 has a groove on one side at each limiting cylinder 12, and a rotating block 16 is rotatably mounted inside each groove. The rotation angle of the rotating block 16 is 180 degrees due to the limitation of the inner wall of the groove. Each rotating block 16 can contact the outer surface of the corresponding limiting cylinder 12.

[0041] Each groove has a fixedly connected rotating shaft 17 inside, and the end of the rotating block 16 is rotatably sleeved on the corresponding rotating shaft 17. Each rotating shaft 17 has a torsion spring sleeved on both ends, one end of the torsion spring is fixedly connected to the inner wall of the groove, and the other end of the torsion spring is fixedly connected to one side of the corresponding rotating block 16. In the initial state, the torsion spring drives the rotating block 16 to rotate to a vertical state, so that the rotating block 16 abuts against the outer surface of the limiting cylinder 12.

[0042] Working principle:

[0043] In the initial state, slide the slide bar 11 into the fixed cylinder 5, and lock the first crossbar 10 into the inside of the inclined groove 6 away from the vertical groove 20. At this time, the spring 7 is compressed and twisted.

[0044] Use bolts to pass through the through holes on the positioning plate 21 to fix the positioning plate 21 and the mounting plate 1 to the mounting location of the electricity meter body 4.

[0045] Move the connecting plate 18 so that it is positioned between the two locking blocks 2, with the locking slots 19 corresponding one-to-one with the locking blocks 2. Push the connecting plate 18 between the two locking blocks 2 so that the locking slots 19 slide on the corresponding locking blocks 2.

[0046] The connecting plate 18 moves between the two fixed plates 3, so that the fixed cylinder 5 corresponds one-to-one with the limiting cylinder 12. When the fixed cylinder 5 drives the sliding rod 11 to move, the end of the sliding rod 11 will abut against the rotating block 16.

[0047] Since the rotating block 16 can no longer rotate, it will press against the slide rod 11. This causes the slide rod 11 to slide into the fixed cylinder 5, continuing to press against the spring 7. Furthermore, under the torsional force of the spring 7, the first horizontal bar 10 moves towards the connection between the inclined groove 6 and the vertical groove 20, while the slide rod 11 rotates. At this point, the slide rod 11 slides past the rotating block 16.

[0048] Move the connecting plate 18 to one side of the mounting plate 1. Since the rotating block 16 no longer blocks the slide bar 11, the spring 7 will continue to push the slide bar 11 to move, and will drive the slide bar 11 to rotate under the action of torsional force, so that the first horizontal bar 10 slides through the vertical groove 20 and the first slide groove 8 in sequence.

[0049] When the first crossbar 10 slides to the middle of the first slide groove 8, the top of the slide bar 11 slides to the corresponding limiting cylinder 12. This causes the second crossbar 15 to slide into the second slide groove 13. After that, the first crossbar 10 slides into the first cross groove 9, and the second crossbar 15 slides into the second cross groove 14.

[0050] Until the first crossbar 10 is located at the end of the first cross groove 9 away from the first slide groove 8, and the second crossbar 15 is located at the end of the second cross groove 14 away from the second slide groove 13. At this time, fix the end of the slide bar 11 in the limiting cylinder 12, fix the connecting plate 18 to one side of the mounting plate 1, and install the electricity meter body 4.

[0051] When disassembling the electricity meter body 4, the first horizontal bar 10 is pushed to slide along the first slide groove 8 and the vertical groove 20 into the inclined groove 6. At the same time, the second horizontal bar 15 slides into the second slide groove 13. The first horizontal bar 10 drives the slide bar 11 to move, and at the same time, the slide bar 11 will rotate, compressing the spring 7 and driving the spring 7 to twist.

[0052] The second crossbar 15 will slide out of the second slide groove 13, causing the slide bar 11 to leave the limiting cylinder 12. Until the first crossbar 10 is locked in the inclined groove 6 at the end away from the vertical groove 20, the connecting plate 18 can be slid out between the two locking blocks 2, thereby disassembling the electricity meter body 4.

[0053] When the connecting plate 18 is removed, the slide bar 11 pushes the rotating block 16 to rotate, and the rotating block 16 does not squeeze the slide bar 11. The end of the rotating block 16 rotates on the rotating shaft 17 and drives the torsion spring on it to twist. After the slide bar 11 leaves the rotating block 16, the torsion spring drives the rotating block 16 to rotate back to its initial state.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
