Description

Technical Field

[0001] The utility model belongs to the technical field of smart meters, and more specifically, particularly relates to a wire clamping device for smart meters. Background Art

[0002] A smart meter is one of the basic devices for data collection in a smart grid (especially a smart distribution network). It undertakes the tasks of collecting, measuring, and transmitting original electrical energy data, and is the basis for realizing information integration, analysis and optimization, and information display. In addition to the basic power consumption measurement function of a traditional electricity meter, in order to adapt to the smart grid and the use of new energy, it also has intelligent functions such as two-way multi-rate measurement function, user-side control function, two-way data communication function with multiple data transmission modes, and anti-stealing electricity function.

[0003] The existing smart meter wire clamping device with the publication number CN213068971U discloses a smart meter wire clamping device. Although by moving the handle to the right, the cross bar can be driven to move to the right. At the same time, the connecting plate moves to the right accordingly, so that the clamping block moves to the right, ensuring that the wire can be located in the inner cavity of the wire slot. By rotating the second connecting rod forward, the device can be turned into a right angle to fix the wire at the corner. The device can effectively fix the wire gap, avoid short circuit caused by mutual collision between wires, and ensure the safety of people.

[0004] Based on the above, the inventor of the present invention found the following problems: However, this smart meter wire clamping device uses a single spring for fastening and limiting, resulting in that when placing wires in other inner cavities, it is easy to excessively compress the spring, causing the wires that have been limited in the previous inner cavity to fall off. At the same time, this smart meter wire clamping device uses a connecting block for connection, and a device suitable for the connecting block needs to be installed correspondingly inside the meter to fix it.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a smart meter wire clamping device is provided in order to achieve a more practical and valuable purpose. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a smart meter wire clamping device to solve the problem that when placing wires in other inner cavities, it is easy to excessively compress the spring, causing the wires that have been limited in the previous inner cavity to fall off.

[0007] The utility model provides a smart meter wire clamping device, which is achieved by the following specific technical means:

[0008] An intelligent electricity meter wire clamping device includes a threaded sleeve rod. A limiting rod is fixed at the top of the threaded sleeve rod. A placement groove is formed on one side of the limiting rod. A through hole is formed through one side of the placement groove. A fixed limiting plate is fixed on one side of the inner wall of the placement groove. A telescopic rod is movably sleeved inside the through hole. A spring is arranged on the outer wall of the telescopic rod. Moving limiting plates are fixed at both ends of the spring. Threaded rods are threadedly connected to both ends of the threaded sleeve rod. A connecting sleeve is rotatably connected to one end of the threaded rod away from the threaded sleeve rod. An extrusion block is fixed on one side of the connecting sleeve.

[0009] Furthermore, both the fixed limiting plate and the moving limiting plate are arc-shaped. A first guiding block and a second guiding block are respectively fixed on the sides of the fixed limiting plate and the moving limiting plate close to the opening of the placement groove. The first guiding block and the second guiding block are arranged in a V shape.

[0010] Furthermore, multiple placement grooves are provided. The multiple placement grooves are arranged horizontally at equal intervals. The number of through holes is half of the number of placement grooves.

[0011] Furthermore, the multiple through holes are respectively located in the middle of two adjacent placement grooves. The two adjacent moving limiting plates on both sides of the through hole are connected by a telescopic rod and a spring.

[0012] Furthermore, the length value of the extrusion block is greater than the diameter value of the threaded sleeve rod. The length value of the threaded sleeve rod is equal to the sum of the length values of the two threaded rods. Rubber pads are fixed on the opposite sides of the two extrusion blocks.

[0013] Furthermore, a protective cover is fixed at the top of the threaded sleeve rod. The protective cover is located on the side of the placement groove close to the fixed limiting plate at the top. A groove is formed through the side of the protective cover close to the opening of the placement groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. When installing or disassembling a wire in the utility model, place the wire on the side of the opening of the first guiding block and the second guiding block, and then press it into the placement groove. The wire can be squeezed into the middle of the fixed limiting plate and the moving limiting plate. When continuing to place the wire on the other side after finishing placing on one side, the spring will only continue to be squeezed and will not affect the previously placed wire. Thus, the effect that multiple springs can respectively limit different wires can be achieved, and the previously placed wire will not be affected when placing other wires.

[0016] 2. In the present utility model, by rotating the threaded rod, the two extrusion blocks can extrude both sides inside the electric meter. The rubber pads are used to increase the friction force, making the threaded sleeve rod and the limiting rod more stable. By adjusting the distance between the two extrusion blocks through the threaded rod, electric meters of various sizes can be adapted, so that the wire clamping device can be directly installed without installing connection components inside the electric meter, and at the same time, the effect of being applicable to electric meters of various sizes can be achieved.

[0017] 3. In the present utility model, through the provided protective cover, after the wire is placed in the middle of the fixed limiting plate and the movable limiting plate, the exposed position of the wire metal can enter the protective cover from the groove. The protective cover is used to protect the wire, preventing the operator from accidentally touching the exposed end of the wire during operation, so as to achieve the effect that the wire placed in the wire clamping device will not be accidentally touched and is safer to use.

[0026] Example:

[0027] As shown in the attached Figure 1 to the attached Figure 4As shown in the figure:

[0028] The utility model provides an intelligent electric meter wire clamping device, which includes a threaded sleeve rod 1. A limiting rod 2 is fixed at the top of the threaded sleeve rod 1. A placement groove 3 is formed on one side of the limiting rod 2. A through hole 8 is formed through one side of the placement groove 3. A fixed limiting plate 4 is fixed on one side of the inner wall of the placement groove 3. A telescopic rod 6 is movably sleeved inside the through hole 8. A spring 7 is arranged on the outer wall of the telescopic rod 6. Moving limiting plates 5 are fixed at both ends of the spring 7. Threaded rods 11 are threadedly connected to both ends of the threaded sleeve rod 1. One end of the threaded rod 11 away from the threaded sleeve rod 1 is rotatably connected to a connecting sleeve 12. An extrusion block 13 is fixed on one side of the connecting sleeve 12.

[0029] Among them, both the fixed limiting plate 4 and the moving limiting plate 5 are arranged in an arc shape. First guiding blocks 41 and second guiding blocks 51 are respectively fixed on the sides of the fixed limiting plate 4 and the moving limiting plate 5 close to the opening of the placement groove 3. The first guiding blocks 41 and the second guiding blocks 51 are arranged in a V shape. The arc-shaped fixed limiting plate 4 and moving limiting plate 5 can better fit the wire and clamp it more tightly. By arranging the first guiding blocks 41 and the second guiding blocks 51, when installing or disassembling the wire, the wire can be placed on the opening side of the first guiding blocks 41 and the second guiding blocks 51, and then pressed into the placement groove 3, and the wire can be squeezed into the middle of the fixed limiting plate 4 and the moving limiting plate 5.

[0030] Among them, multiple placement grooves 3 are provided. The multiple placement grooves 3 are arranged horizontally at equal intervals. The number of through holes 8 is half of the number of placement grooves 3. By arranging a spring 7 inside the through hole 8, one spring 7 connects two moving limiting plates 5. The length of the spring 8 is long enough. When no wire is placed, the two moving limiting plates 5 can touch the two fixed limiting plates 4.

[0031] Among them, the multiple through holes 8 are respectively located in the middle of two adjacent placement grooves 3. The two adjacent moving limiting plates 5 on both sides of the through hole 8 are connected by a telescopic rod 6 and a spring 7. When squeezing the wire into the middle of the fixed limiting plate 4 and the moving limiting plate 5, the second guiding block 51 will push the spring 7 and the telescopic rod 6 to shorten. When placing the wire on the other side, the spring 7 will only continue to be squeezed without affecting the previously placed wire.

[0032] Among them, the length value of the extrusion block 13 is greater than the diameter value of the threaded sleeve rod 1. The length value of the threaded sleeve rod 1 is equal to the sum of the length values of the two threaded rods 11. Rubber pads are fixed on the opposite sides of the two extrusion blocks 13. By rotating the threaded rod 11, the two extrusion blocks 13 can squeeze both sides inside the electric meter. By increasing the friction force through the rubber pads, the threaded sleeve rod 1 and the limiting rod 2 are fixed more stably. By adjusting the distance between the two extrusion blocks 13 through the threaded rod 11, electric meters of various sizes can be adapted.

[0033] Among them, a protective cover 9 is fixed to the top of the threaded sleeve rod 1. The protective cover 9 is located on the top of the placement groove 3, close to one side of the fixed limit plate 4. A groove 10 is formed through the side of the protective cover 9 close to the opening of the placement groove 3. By providing the protective cover 9, after the wire is placed in the middle of the fixed limit plate 4 and the movable limit plate 5, the exposed position of the wire metal can enter the protective cover 9 from the groove 10, and the protective cover 9 protects the wire to prevent the operator from accidentally touching the exposed end of the wire during operation.

[0034] Specific usage method and function of this embodiment:

[0035] In this utility model, first rotate the threaded rod 11 so that the two extrusion blocks 13 can extrude both sides inside the electric meter. The rubber pads increase the friction force, making the fixation of the threaded sleeve rod 1 and the limit rod 2 more stable. By adjusting the distance between the two extrusion blocks 13 through the threaded rod 11, electric meters of various sizes can be adapted. When installing or disassembling the wire, place the wire on the open side of the first guide block 41 and the second guide block 51, and then press it into the placement groove 3. The wire can be extruded into the middle of the fixed limit plate 4 and the movable limit plate 5. The arc-shaped fixed limit plate 4 and movable limit plate 5 can better fit the wire and clamp it more tightly. The length of the spring 8 is long enough. When no wire is placed, the two movable limit plates 5 can touch the two fixed limit plates 4. When the wire is extruded into the middle of the fixed limit plate 4 and the movable limit plate 5, the second guide block 51 will push the spring 7 and the telescopic rod 6 to shorten. When placing the wire on the other side, the spring 7 will only continue to be compressed and will not affect the previously placed wire. By providing the protective cover 9, after the wire is placed in the middle of the fixed limit plate 4 and the movable limit plate 5, the exposed position of the wire metal can enter the protective cover 9 from the groove 10, and the protective cover 9 protects the wire to prevent the operator from accidentally touching the exposed end of the wire during operation.
