Description

Technical Field

[0001] This utility model belongs to the field of electricity meter testing technology, specifically relating to an electricity meter calibration device with an adjustable clamping mechanism. Background Technology

[0002] In the production and maintenance of electricity meters, calibration is a crucial step in ensuring metering accuracy. The calibration device needs to stably clamp the electricity meter to ensure a fixed position and reliable contact during testing. Traditional calibration equipment often uses fixed or bolt-locking clamps, where the clamping position is not adjustable or requires tools for adjustment, making operation cumbersome and difficult to adapt to the rapid clamping requirements of different specifications of electricity meters.

[0003] In the existing technology, traditional electricity meter calibration devices are mostly installed by bolt fixing. When it is necessary to adjust its position, tools are required to disassemble or loosen the bolts, which is cumbersome, has low adjustment efficiency, and makes it difficult to achieve rapid positioning and repeated clamping, affecting the continuity and flexibility of calibration work. Utility Model Content

[0012] As a preferred embodiment of this utility model, one end of the first spring abuts against the button and the other end abuts against the slider, which is used to apply an elastic restoring force to the locking block.

[0013] As a preferred embodiment of this utility model, the buttons are symmetrically arranged on both sides of the outer surface of the slider, and the locking block is locked into the slot under the action of the spring force, thereby locking the position of the slider on the fixed frame.

[0014] As a preferred embodiment of this utility model, the threaded rod passes through the fixing block and extends to both sides, with positioning blocks at both ends, and the positioning blocks are in contact with the surface of the clamping plate.

[0027] Example

[0028] Reference Figures 1-5 This embodiment of the present invention provides an energy meter calibration device with an adjustable clamping mechanism, comprising:

[0029] The support mechanism 100 includes a fixed frame 101, slots 102 formed on both sides of the outer surface of the fixed frame 101, and a slider 103 that slides in cooperation with the outer surface of the fixed frame 101.

[0030] The locking mechanism 200 includes a button 201 that slides with the slider 103, a first spring 202 that is fixedly connected to the outer surface of the button 201, a locking block 203 that is fixedly connected to the outer surface of the button 201, and a clamping assembly 204 for fixing the meter.

[0031] The clamping assembly 204 includes a fixing block 204a fixedly mounted on the outer surface of the slider 103, a threaded rod 204b fixedly connected to the inner surface of the fixing block 204a, and a fixing nut 204c threadedly connected to the threaded rod 204b.

[0032] Specifically, the clamping assembly 204 also includes a second spring 204d sleeved on the outer surface of the threaded rod 204b, and a clamping plate 204e threadedly connected to both ends of the threaded rod 204b.

[0033] When it is necessary to fix the energy meter, the fixing nut 204c is rotated. Under the action of the threaded transmission, the fixing nut 204c moves axially along the threaded rod 204b, applying a pushing force to the clamping plate 204e. This pushing force pushes the clamping plate 204e to move inward, compressing the second spring 204d, so that the two clamping plates 204e come closer to each other, thereby clamping the energy meter. The second spring 204d provides a continuous preload under compression to prevent the clamping from loosening and ensure that the energy meter remains stable during the calibration process.

[0034] Furthermore, the slots 102 are symmetrically arranged on both sides of the fixing frame 101 and are distributed in a linear array along its length direction. The outer surface of the fixing frame 101 slides in contact with the inner surface of the slider 103.

[0035] Furthermore, one end of the first spring 202 abuts against the button 201, and the other end abuts against the slider 103, for applying an elastic restoring force to the locking block 203.

[0036] When the position of the electricity meter needs to be adjusted, the buttons 201 on both sides of the slider 103 can be pressed simultaneously. After the buttons 201 are subjected to force, they compress the first spring 202 and drive the locking block 203 fixedly connected to it to disengage from the slot 102, thus releasing the locked state. Then, the slider 103 is slid along the length of the fixing frame 101, which drives the clamping assembly 204 to move to the target position. After the adjustment is completed, the buttons 201 are released. Under the action of the elastic restoring force, the first spring 202 pushes the buttons 201 to reset, so that the locking block 203 is re-locked into the corresponding slot 102, thus realizing the automatic locking of the slider 103 in the new position.

[0037] Furthermore, the buttons 201 are symmetrically arranged on both sides of the outer surface of the slider 103, and the locking block 203 is locked into the slot 102 under the action of the spring force, thereby locking the position of the slider 103 on the fixing frame 101.

[0038] Preferably, the threaded rod 204b passes through the fixing block 204a and extends to both sides, with positioning blocks at both ends, and the positioning blocks are in contact with the surface of the clamping plate 204e.

[0039] It should be noted that one end of the second spring 204d is fixedly connected to the inner surface of the fixing block 204a, and the other end is fixedly connected to the clamping plate 204e.

[0040] In use, first place the energy meter to be calibrated between the two clamping plates 204e. Then, rotate the fixing nut 204c. Under the action of the threaded drive, the fixing nut 204c moves axially along the threaded rod 204b, applying a pushing force to the clamping plate 204e, pushing the clamping plate 204e inward, compressing the second spring 204d sleeved on the threaded rod 204b, and bringing the two clamping plates 204e closer together, thereby achieving stable clamping of the energy meter. The second spring 204d provides a continuous elastic preload under compression, effectively buffering vibration and shock, preventing loosening of the clamp, and avoiding damage to the energy meter casing from rigid contact. When adjustment is required... When the dial indicator is in a horizontal position, the buttons 201 on both sides of the slider 103 can be pressed simultaneously. After the buttons 201 are subjected to force, they compress the first spring 202 and drive the locking block 203 fixedly connected to it to disengage from the slot 102, thus releasing the locked state. Then, the slider 103 is slid along the length of the fixing frame 101, which drives the clamping assembly 204 fixed on it to move to the target position. After the adjustment is completed, the buttons 201 are released. The first spring 202 pushes the buttons 201 to reset under the action of elastic restoring force, so that the locking block 203 is re-locked into the corresponding slot 102 on the fixing frame 101, thus realizing the automatic locking of the slider 103 in the new position.

[0041] In summary, through the cooperation of the bearing mechanism 100 and the locking mechanism 200, the clamping component 204 can be quickly adjusted and automatically positioned and locked on the fixed frame 101 without tools. The user can unlock and move it by pressing the button 201. After releasing, it will automatically snap into the slot 102 under the action of the first spring 202, achieving rapid positioning. At the same time, the clamping component 204 drives the fixed nut 204c to move axially along the threaded rod 204b by rotating the fixed nut 204c, pushing the clamping plate 204e to move inward and compressing the second spring 204d, so that the two clamping plates 204e move closer to each other synchronously, applying a stable clamping force to the energy meter, thereby improving the efficiency and flexibility of the calibration operation.
