Specific implementation

[0025] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be introduced further in the following with the annex.

[0026] The utility model discloses a kind of intelligent weight counting equipment internet of things mainboard.

[0027] The utility model provides a kind of intelligent weight counting equipment internet of things mainboard as Figures 1-4 As shown in the drawing, an intelligent weight counting equipment internet of things mainboard includes weight counting equipment shell 1 and the mainboard body 2 in weight counting equipment shell 1 inside, rubber support block 15 is fixedly arranged at the bottom four corners of mainboard body 2, rubber support block 15 is contacted with the inner wall bottom of weight counting equipment shell 1, installation hole 3 is arranged at the inside four corners of mainboard body 2, drive pipe 4 is rotationally arranged in installation hole 3, mounting screw 5 is screwedly arranged in drive pipe 4, the top of mounting screw 5 is provided with longitudinal limiting mechanism, longitudinal limiting mechanism is used to limit the transverse rotation of mounting screw 5, longitudinal limiting mechanism includes limiting plate 10, limiting plate 10 is inserted with the top of mounting screw 5 and is matched, the top of limiting plate 10 is fixed with elastic telescopic rod 11, the top of elastic telescopic rod 11 is fixed with mounting bracket 12, the lower end of the outer wall of mounting bracket 12 is fixed with mounting plate 13, and mounting plate 13 is connected with the top of mainboard body 2.

[0028] The outer wall of mainboard body 2 is provided with annular groove 6, annular groove 6 is communicated with a plurality of installation holes 3, and is provided with synchronous drive mechanism for driving a plurality of drive pipes 4 to rotate simultaneously in the inside, and synchronous drive mechanism includes transmission belt 7, transmission belt 7 is arranged in annular groove 6, and is in transmission contact with the outer wall of a plurality of drive pipes 4.

[0029] When installing the IoT motherboard of the smart weighing equipment, first place the motherboard body 2 inside the weighing equipment shell 1. The rubber support block 15 plays a supporting and buffering role, avoiding direct contact between the motherboard body 2 and the weighing equipment shell 1, and reducing the impact of vibration on the motherboard.

[0030] At this time, the mounting screw 5 is inside the drive tube 4, and the limiting plate 10 is inserted into the screw-in groove at the top of the mounting screw 5. Due to the plug-in connection between the limiting plate 10 and the mounting screw 5, the lateral rotation of the mounting screw 5 is restricted, so that it can only move up and down inside the drive tube 4. Therefore, when the motherboard needs to be installed, the transmission belt 7 is rotated, and the transmission belt 7 drives the drive tube 4 to rotate. Because the drive tube 4 and the mounting screw 5 are threadedly connected, and the mounting screw 5 cannot rotate laterally, the rotation of the drive tube 4 will cause the mounting screw 5 to move downward until the mounting screw 5 is connected to the corresponding threaded hole on the weighing equipment housing 1 and tightened, thereby realizing the quick installation of the motherboard body 2 and the weighing equipment housing 1. When disassembling, the transmission belt 7 is rotated in the opposite direction, and the mounting screw 5 moves upward and disengages from the threaded hole of the weighing equipment housing 1, so that the motherboard body 2 can be easily removed.

[0031] To ensure that multiple drive tubes 4 can rotate stably and synchronously when the transmission belt 6 rotates, such as Figure 4 As shown, the inner wall of the transmission belt 7 is provided with a plurality of spaced limiting grooves 8, and the outer wall of the drive tube 4 is fixed with a plurality of limiting blocks 9 arranged in a circumferential symmetrical manner. The limiting blocks 9 are inserted into the limiting grooves 8.

[0032] The limiting groove 8 on the inner wall of the transmission belt 7 is inserted into the limiting block 9 on the outer wall of the drive tube 4. When the transmission belt 7 rotates, the limiting block 9 moves along the limiting groove 8. This design ensures that the transmission belt 7 will not slip on the drive tube 4, so that multiple drive tubes 4 can rotate stably and synchronously.

[0033] To facilitate the connection of mounting screw 5 to drive tube 4, such as Figure 1 As shown, a positioning bolt 14 is threadedly connected between the mounting plate 13 and the main body 2.

[0034] The mounting plate 13 is threadedly connected to the main body 2 via positioning bolts 14. Before the mounting screw 5 is connected to the drive tube 4, this connection method facilitates the adjustment of the positions of the mounting bracket 12, the elastic telescopic rod 11, and the limiting plate 10, so that the limiting plate 10 can be accurately inserted into the screw-in groove at the top of the mounting screw 5. During installation, first loosen the positioning bolts 14, finely adjust the position of the mounting plate 13 so that the limiting plate 10 is aligned with the screw-in groove of the mounting screw 5 and inserted. Then tighten the positioning bolts 14 to fix the position of the mounting plate 13. In this way, when the transmission belt 7 drives the drive tube 4, the limiting plate 10 can stably restrict the lateral rotation of the mounting screw 5, ensuring that the mounting screw 5 can be smoothly connected or separated from the weighing equipment housing 1.

[0035] Certain exemplary embodiments of this application are described herein by way of illustration, and not limitation, and it is to be understood that the application can be carried out with various modifications within the spirit and scope of the application, which are to be understood as being limited only by the appended patent claims as interpreted in accordance with the principles of patent law.
