[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a clamp for cutting an electric meter box, including a positioning table 1, and two box limiting mechanisms are symmetrically arranged on the top surface of the positioning table 1.

[0025] The box limiting mechanism includes two fixed plates 6 symmetrically fixed to the top surface of the positioning platform 1 by bolts. Each fixed plate 6 has two support seats 10 symmetrically fixed to its top surface, and the meter box is located on the top surface of the support seat 10. A slide seat 7 is provided on the top surface of the fixed plate 6. A slide groove is opened on the top surface of the support seat 10. The slide seat 7 is inserted into the slide groove by a slider fixed to the bottom and is slidably connected to the fixed plate 6. A limiting top plate 9 is slidably connected inside the slide seat 7. A second lead screw 12 is rotatably connected inside the slide seat 7 by a bearing. The second lead screw 12 is threadedly connected to the limiting top plate 9 by a threaded cylinder.

[0026] Two limiting top plates 9 are located inside the meter box and fit against the inner wall of the meter box. Each slide 7 has a fixedly connected positioning force plate 8 on its top surface. The positioning force plate 8 and the limiting top plate 9 are on the same axis. The positioning force plate 8 and the limiting top plate 9 have the same shape, both being Y-shaped structures.

[0027] The top surface of the fixing plate 6 is provided with a positioning groove 11, which is parallel to the slide groove. A screw is threadedly connected to one side of the slide block 7. A rubber pad is fixedly connected to the bottom end of the screw, and the bottom end of the screw is inserted into the interior of the positioning groove 11 and fits against the fixing plate 6.

[0028] When it is necessary to modify and cut the meter box, place the meter box on the positioning platform 1 so that the position of the meter box is on the top surface of the support base 10. The support base 10 supports the meter box. At this time, the edge of the meter box should be between the limiting top plate 9 and the positioning force plate 8. The two positioning force plates 8 initially limit the position of the meter box.

[0029] After the meter box is placed, force is applied to the slide block 7, causing it to move above the fixing plate 6 through the sliding groove until it moves to the same axis as the positioning force plate 8 and the position to be modified. Then, force is applied to the slide block 7, causing it to rotate. The bottom end of the screw will extend into the positioning groove 11, and the rubber pad connected to the bottom end of the screw will fit against the support base 10. The friction between the rubber pad and the support base 10 limits the position of the slide block 7.

[0030] Once the position of the slide block 7 is defined, force is applied to the second lead screw 12, causing the second lead screw 12 to rotate inside the slide block 7. This allows the threaded cylinder to drive the limiting top plate 9 to move towards the inner wall of the meter box and fit against the inner wall of the meter box. Since the positioning force plate 8 has already limited the meter box, when the limiting top plate 9 is in close contact with the inner wall of the meter box, it will cooperate with the positioning force plate 8 to clamp the meter box, thus achieving initial clamping of the meter box.

[0031] After the positioning force plate 8 and the limiting top plate 9 clamp the meter box, the workers can cut the marked position using external construction tools. During the cutting process, the construction tools apply force to the meter box, and the limiting top plate 9 located on the inner wall of the meter box provides local support to the meter box, thereby preventing deformation of the cut part of the meter box. The positioning force plate 8 located on the outer side of the meter box can align the limiting top plate 9 with the cut part and also prevent the construction tools from bumping and impacting the meter box during cutting, thus avoiding squeezing and deformation of the meter box.

[0032] In this utility model, the top surface of the positioning platform 1 is symmetrically and fixedly connected to two fixed limiting frames 2. Each fixed limiting frame 2 has a slidably connected positioning pressure plate 3 inside. The two positioning pressure plates 3 are connected to each other through a linkage rod 13. The top surface of the positioning platform 1 is rotatably connected to a first lead screw 5 through a bearing seat. The first lead screw 5 is located between the two fixed limiting frames 2. The first lead screw 5 is threadedly connected to the linkage rod 13 through a threaded cylinder. Each positioning pressure plate 3 has a flexible block 4 fixedly connected to the side adjacent to the fixed limiting frame 2. Several transverse grooves are opened on the side of the two flexible blocks 4 adjacent to each other.

[0033] To prevent the meter box from shaking when adjusting the cutting position, while the meter box is placed on the top surface of the support base 10, one side of the meter box will also be in contact with the top surface of the fixed limiting frame 2. Then, force is applied to the first lead screw 5 to make it rotate. The rotation of the first lead screw 5 will move the two positioning pressure plates 3 towards the inner wall of the meter box through the linkage rod 13. The two positioning pressure plates 3 will drive the flexible blocks 4 to move. The two opposing flexible blocks 4 on the same side will be in contact with the inner and outer surfaces of the meter box. The positioning pressure plates 3 and the fixed limiting frame 2 cooperate to clamp and limit the meter box. The two flexible blocks 4 make the fixed limiting frame 2, the positioning pressure plates 3 and the meter box make flexible contact, preventing the meter box from deforming due to compression.

[0034] It should be noted that in this application, an annular groove is provided axially on the inner wall of the threaded cylinder or threaded hole, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. Through the continuous axial clamping force generated by its elastic deformation, the first lead screw 5, the second lead screw 12 and the screw surface form a helical angle interference fit of 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 according to the ASTM D1894 standard test, effectively suppressing the loosening displacement caused by thread springback.

[0035] The use of this utility model involves the following steps:

[0036] S1: When it is necessary to modify and cut the meter box, place the meter box on the top of the positioning platform 1 so that the position of the meter box is on the top surface of the support base 10. The support base 10 supports the meter box. At this time, the edge of the meter box should be between the limiting top plate 9 and the positioning force plate 8. The two positioning force plates 8 initially limit the position of the meter box.

[0037] S2: After the meter box is placed, apply force to the slide block 7 to move it above the fixed plate 6 through the slide groove until the positioning force plate 8 and the position to be modified are on the same axis. Then stop applying force to the slide block 7 and apply force to the screw to make the screw rotate. The bottom end of the screw will extend into the interior of the positioning groove 11. The rubber pad connected to the bottom end of the screw will fit against the support seat 10. The position of the slide block 7 is limited by the friction between the rubber pad and the support seat 10.

[0038] S3: After the position of the slide block 7 is defined, force is applied to the second lead screw 12, causing the second lead screw 12 to rotate inside the slide block 7. This allows the limiting top plate 9 to move towards the inner wall of the meter box via the threaded cylinder and fit against the inner wall of the meter box. Since the positioning force plate 8 has already limited the meter box, when the limiting top plate 9 is in close contact with the inner wall of the meter box, it will cooperate with the positioning force plate 8 to clamp the meter box, thus achieving the initial clamping of the meter box.

[0039] S4: After the positioning force plate 8 and the limiting top plate 9 clamp the meter box, the workers can cut the marked position with external construction tools. When cutting, the construction tools apply force to the meter box, and the limiting top plate 9 located on the inner wall of the meter box will provide local support to the meter box, thereby preventing deformation of the cut part of the meter box. The positioning force plate 8 located on the outer side of the meter box can align the limiting top plate 9 with the cut part, and also prevent the construction tools from bumping and hitting the meter box when cutting, thereby preventing the meter box from being squeezed and deformed.

[0040] S5: To prevent the meter box from shaking when adjusting the cutting position, while the meter box is placed on the top surface of the support base 10, one side of the meter box will also be in contact with the top surface of the fixed limiting frame 2. Then, force is applied to the first lead screw 5 to make it rotate. The rotation of the first lead screw 5 will move the two positioning pressure plates 3 towards the inner wall of the meter box through the linkage rod 13. The two positioning pressure plates 3 will drive the flexible blocks 4 to move. The two opposing flexible blocks 4 on the same side will be in contact with the inner and outer surfaces of the meter box. The clamping and limiting of the meter box is achieved through the cooperation of the positioning pressure plates 3 and the fixed limiting frame 2. The two flexible blocks 4 make the fixed limiting frame 2, the positioning pressure plates 3 and the meter box make flexible contact to prevent the meter box from deforming due to compression.
