[0014] 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.

[0015] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 As shown, this utility model is a weighing instrument accessory installation and disassembly device, comprising: The positioning groove 11, the positioning block 12, and the positioning column 13 are provided. The positioning groove 11 is located in the middle of the upper part of the weighing instrument base 21. The positioning block 12 is slidably connected in the positioning groove 11, and the upper end of the positioning block 12 is threadedly fixed to the base 21 of the weighing instrument load cell. The positioning column 13 is fixedly connected to the middle of the back of the positioning block 12, and one end of the positioning column 13 is fitted with an opening provided at one end of the positioning groove 11. A movable column 15 is fixed on one side of the lower front of the positioning block 12. The positioning groove 11 has symmetrical limiting grooves on both sides inside. The positioning block 12 has symmetrical limiting blocks 14 fixed on both sides. The outer side of the limiting block 14 extends into the limiting groove, and the two are slidably connected. The positioning groove 11 provides an installation base for the positioning block 12 and the limiting groove. The weight sensor is installed through the positioning block 12, and the sliding in the positioning groove 11 and the sliding in the limiting groove of the limiting block 14 can provide a guide for the installation and removal position. At the same time, the movement position is limited by the abutment between the limiting block 14 and the inner wall of the limiting groove. The fitting between the positioning post 13 and the opening fixes the positioning block 12 during installation, that is, fixes the weight sensor.

[0017] The movable column 15 has a perforated protrusion in the center of its front side; The perforated protrusions can be used to attach external ropes, allowing for neat storage of the structure when multiple movable columns 15 are not in use.

[0018] Working principle: When disassembling the load cell, directly disassemble the movable plate inside the disassembly opening on the front of the weighing instrument. Grasp the movable column 15 and apply force to the positioning block 12. Utilize the sliding of the positioning block 12 in the positioning groove 11 and the sliding of the limiting block 14 in the limiting groove, and under the continuous application of force, the positioning column 13 is disengaged from the hole, thus moving the load cell that is deep inside out. The disassembly and assembly can then be completed on the outside of the weighing instrument. When reinstalling the load cell inside the weighing instrument, the above reverse operation steps can be applied again.

[0019] This solution allows for easy assembly and disassembly from the outside, saving time and effort and significantly improving assembly and disassembly efficiency.

[0020] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment: It also includes an auxiliary disassembly assembly, which includes a hole block 22 and a rack 26. Two hole blocks 22 are symmetrically arranged. A winding drum 24 is provided inside the two hole blocks 22. A rotating gear 25 is sleeved on one side of the outer surface of the winding drum 24. The rack 26 is fixedly connected to the upper part of the outer surface of the movable column 15, and the rack 26 meshes with the rotating gear 25. The winding drum 24 has shafts 23 on both sides in the middle, and the shafts 23 pass through the bearings provided on the upper part of the two holes 22; The hole block 22 is fitted with the shaft seat and the shaft rod 23 is used to support and install the winding drum 24. The winding drum 24 can be used to wind up the wire when the weighing device is disassembled. The meshing between the rack 26 and the rotating gear 25 can actively drive the rotating gear 25 to rotate the winding drum 24 when the movable column 15 extends outward, so as to wind up the wire.

[0021] The bottom ends of the two holes 22 are fixed with bases 21, and the bottom ends of the bases 21 are flush with the bottom ends of the weighing instrument. The flat bottom design increases the stability of the weighing instrument by increasing the structural friction area.

[0022] The inner end of the base 21 is provided with a columnar protrusion, and the columnar protrusion fits into the groove provided at the lower end of the front of the weighing instrument. The fitting between the columnar protrusion and the groove structurally fixes the base 21.

[0023] Working principle: During the process of removing the load cell from the weighing instrument for maintenance, as the movable column 15 moves outward, the rack 26 on the movable column 15 meshes with the rotating gear 25 on the winding drum 24, causing the rotating gear 25 to rotate and the winding drum 24 to rotate, thus synchronously winding up the wire. When the load cell is subsequently reinstalled into the weighing instrument, the winding drum 24, rotating in the opposite direction, actively unwinds the wire.

[0024] This solution can proactively manage the winding and unwinding of the load cell's wires during assembly and disassembly, further improving operational efficiency.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
