DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 A flat modular dynamic vehicle scale weighing device comprises a base 1, with inclined seats 2 fixedly installed on both sides of the base 1, a weighing plate 3 is arranged above the base 1, a plurality of positioning plates 4 are fixedly installed on the lower surface of the weighing plate 3, and positioning grooves are opened on the lower surfaces of the plurality of positioning plates 4;

[0024] A plurality of mounting grooves are provided on the base 1, and a threaded rod 5 with opposite thread directions at the left and right ends is horizontally rotatably installed in the mounting groove, a trapezoidal block 6 is symmetrically threadedly sleeved on the threaded rod 5, a weighing sensor 7 is placed between the two trapezoidal blocks 6, and the output end of the weighing sensor 7 is inserted into the positioning groove, and a transmission assembly for driving the threaded rod 5 to rotate is provided in the mounting groove, and the rotating assembly includes a rotating rod 8 rotatably installed in the mounting groove through a support block, a first bevel gear 9 fixedly installed at one end of the rotating rod 8, and a second bevel gear 10 fixedly sleeved on the threaded rod 5, and the first bevel gear 9 is meshedly connected with the second bevel gear 10;

[0025] The weighing sensor 7 is placed on the two trapezoidal blocks 6, and the lower end of the weighing sensor 7 is in contact with the inclined surfaces of the two trapezoidal blocks 6. When the weighing sensor 7 is damaged, the maintenance personnel can rotate the rotating rod 8 to drive the first bevel gear 9 to rotate. Since the first bevel gear 9 is meshed and connected with the second bevel gear 10, the threaded rod 5 can be driven to rotate. Since the left and right ends of the threaded rod 5 have opposite thread directions, when the threaded rod 5 rotates, the two trapezoidal blocks 6 will be driven away from each other, and the weighing sensor 7 will move vertically downward along the inclined surfaces of the two trapezoidal blocks 6 until the output end of the weighing sensor 7 is removed from the positioning groove starting from the positioning plate 4. Then the weighing sensor 7 can be removed from the two trapezoidal blocks 6 for maintenance. The disassembly process is very convenient, saving time and effort.

[0026] The rotating rod 8 is provided with a thread, and a moving block 11 is threadedly sleeved on the rotating rod 8. A support rod 12 is rotatably mounted on the moving block 11. An L-shaped plate 13 is rotatably mounted on one end of the support rod 12 away from the moving block 11. The support rod 12 is made of elastic material.

[0027] When the automobile scale weighing device is in use, the support rod 12 is rotated to separate the L-shaped plate 13 on the support rod 12 from the positioning plate 4. When the weighing sensor 7 fails, the support rod 12 is rotated to make the L-shaped plate 13 contact one side of the positioning plate 4. When the rotating rod 8 rotates, under the action of the thread, it will drive the moving block 11 to move toward the first bevel gear 9. At this time, the support rod 12 will apply a vertical upward supporting force to the L-shaped plate 13, so that the L-shaped plate 13 supports the weighing plate 3. As the moving block 11 continues to move, the support rod 12 will undergo elastic deformation, and the weighing plate 3 is supported by the elastic force generated by the elastic deformation of the support rod 12, so as to prevent the weighing plate 3 from tilting after losing the support of the weighing sensor 7, thereby damaging the remaining weighing sensors 7.

[0028] A rectangular block 14 is installed at one end of the rotating rod 8 through a connecting assembly. A plug hole is opened on the surface of the rectangular block 14, and a rotating rod 15 is slidably inserted in the plug hole. The connecting assembly includes a hexagonal column 16 fixedly installed on the rectangular block 14 and a hexagonal slot 17 opened at one end of the rotating rod 8. The hexagonal column 16 is inserted into the hexagonal slot 17;

[0029] When it is necessary to drive the rotating rod 8 to rotate, the hexagonal column 16 on the rectangular block 14 can be inserted into the hexagonal slot 17 to complete the connection between the rectangular block 14 and the rotating rod 8, and then the rotating rod 15 can be moved to increase the torque from one end of the rotating rod 15 to the rotating rod 8, so that the rotating rod 8 can be driven to rotate through the rotating rod 15, which is more labor-saving.

[0030] A protective cover is fixedly sleeved on the surface of the rotating rod 15 . The protective cover is made of rubber. When the rotating rod 15 is rotated, the protective cover can protect the palm.

[0031] In the utility model, when the weighing sensor 7 is damaged, the maintenance personnel can drive the threaded rod 5 to rotate through the transmission assembly, and then drive the two trapezoidal blocks 6 to move away from each other. The weighing sensor 7 will move vertically downward along the inclined surfaces of the two trapezoidal blocks 6 until the output end of the weighing sensor 7 moves out of the positioning groove starting from the positioning plate 4. Then the weighing sensor 7 can be removed from the two trapezoidal blocks 6 for maintenance. The disassembly process is very convenient, saving time and effort.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
