Technical Field
[0001] The utility model relates to the technical field of maintenance auxiliary equipment, and specifically, to a maintenance device for an electronic scale. Background Art
[0002] The existing electronic scale includes a weighing platform, a column and an operation panel. Most of the faults of the electronic scale occur in the battery or other electrical components in the operation panel. When performing maintenance, the operator first removes the front cover of the operation panel, and then uses a voltmeter to check the battery or other electrical components.
[0003] The above operation has the following disadvantages: Components such as a display screen are installed inside the front cover of the operation panel.

[0038] The following further describes the present utility model in conjunction with the drawings and specific embodiments:
[0039] As Figure 1 shown, the existing electronic scale includes a weighing platform 1, a column 2, and an operation panel 3. Most of the faults of the electronic scale occur in the battery or other electrical components inside the operation panel 3. During maintenance, the operator first removes the front cover of the operation panel 3, and then uses a voltmeter to check the battery or other electrical components.
[0040] The above operations have the following disadvantages: Components such as a display screen are installed inside the front cover of the operation panel 3. After removing the front cover of the operation panel 3, the front cover and the rear cover of the operation panel 3 are still connected by wires. During the inspection and maintenance process, the front cover of the operation panel 3 has no support and naturally sags under the action of gravity. The solder joints or plugs of the wires are subjected to greater stress, which is likely to cause poor contact and result in new faults.
[0041] As Figures 1 to 7As shown in the figure, an electronic scale repair device includes a placement table 4. Preferably, the shape of the placement table 4 is rectangular.

[0053] During use, one pull ring 13 controls the two ratchet shift levers 16, which is convenient to use.
[0054] The number of gears 14 on each side of the handle 6 is two. The two gears 14 are coaxially arranged, and the ratchet 15 is located between the two gears 14.
[0055] During use, the movement is stable.
[0056] The shape of the movable fixing block 10 is V-shaped, and the shape of the fixed fixing block 9 is V-shaped.
[0057] During use, the clamping effect of the column 2 is better.
[0058] The movable fixing block 10 and the fixed fixing block 9 are made of rubber.
