Description

Technical Field

[0001] This invention relates to the field of electronic scale technology, and in particular to an electronic scale weighing module box and the electronic scale thereof. Background Technology

[0002] In supermarkets and various retail stores, we can see all kinds of electronic scales used in conjunction with the POS system. These small and convenient electronic scales have brought a lot of convenience to our lives.

[0003] In the prior art, Chinese patent application CN201822054025.6 discloses an electronic scale weighing module box and an electronic scale thereof. The electronic scale weighing module box contains a weighing sensor and a wiring module connected to the weighing sensor. When in use, the weighing module box only needs to be fixed to the bottom bracket with screws, while other components such as the display unit can be movably installed within the electronic scale frame. This movable installation contrasts with traditional fixed connections such as welding; that is, if there is a problem with the internal components or other connecting devices, they can be replaced at any time by loosening the screws or plugging and unplugging them. Due to the flexibility of installation, some devices can be upgraded or expanded later.

[0004] However, when using the aforementioned electronic scale weighing module box, compared to an electronic scale directly installed in the housing, the separately set electronic scale weighing module box is less stable and prone to slight movement, which can lead to the wiring coming loose and affect the use of the electronic scale. Therefore, it is necessary to design an electronic scale weighing module box and an electronic scale thereof to solve the problem of unstable wiring when using the existing electronic scale weighing module box.

[0047] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0048] This invention provides an electronic scale weighing module box, such as... Figure 1 As shown, it includes: a box body 1, a weighing module 2 and a processor 3. The weighing module and the processor 3 are both disposed in the box body 1, and the processor 3 is electrically connected to the weighing module. A wire groove 11 is provided on the top wall of the box body 1. A main connecting wire 12 is disposed in the wire groove 11. One end of the main connecting wire 12 is electrically connected to the processor 3, and the other end is fixedly provided with a plug 13.

[0049] The working principle and beneficial technical effects of the above technical solution: When using the weighing module box, the weighing module 2 and the processor 3 are both placed inside the box 1, thereby achieving modular design and facilitating installation and application in various electronic scales. During installation, the main connecting cable 12 and the plug 13 are pulled out and then plugged into the interface of the electronic scale. Since the plug 13 is not directly fixed to the box 1 at this time, even if the box 1 shakes, the wiring will not become loose, thus solving the problem of unstable wiring in the prior art.

[0050] This invention also provides an electronic scale, such as... Figure 2 As shown, the device includes an electronic scale weighing module box, a housing 4, and a fixing component 5. The housing 4 has a weighing cavity 501 with an opening facing downwards. The top wall of the weighing cavity 501 has an insertion hole 41. The box body 1 is disposed in the weighing cavity 501, and the plug 13 is inserted into the insertion hole 41. The fixing component 5 is disposed in the weighing cavity 501 to fix the position of the box body 1.

[0051] The working principle and beneficial technical effects of the above technical solution: When using the electronic scale, first plug 13 is inserted into socket 41, then box 1 is installed in weighing chamber 501, and then box 1 is fixed by fixing component 5, which facilitates later maintenance and replacement and improves the practicality of the device.

[0052] In one embodiment, such as Figure 3 and Figure 4 As shown, the fixing component 5 includes:

[0053] Two first rotating shafts 502 are symmetrically arranged on both sides of the weighing cavity 501. The first rotating shafts 502 are horizontally arranged and rotatably connected to the housing 4. A torsion spring 503 is arranged between the first rotating shaft 502 and the housing 4. A first limiting block 504 is fixedly arranged on the first rotating shaft 502. The first limiting block 504 is set with a semi-circular structure. A first sprocket 505 is also fixedly arranged coaxially on the first rotating shaft 502.

[0054] The second rotating shaft 506 is provided on the side of the first rotating shaft 502 away from the weighing chamber 501. The second rotating shaft 506 is parallel to the first rotating shaft 502 and rotatably connected to the housing 4. A second sprocket 507 is fixedly provided on the second rotating shaft 506. The second sprocket 507 is connected to the first sprocket 505 by a chain for transmission.

[0055] A first gear 508 is fixedly mounted on the second rotating shaft 506. A drive slide groove 509 is provided below the first gear 508. The drive slide groove 509 is horizontally positioned and points towards the weighing cavity 501. The drive slide groove 509 communicates with the weighing cavity 501. A limiting rack 510 is slidably mounted inside the drive slide groove 509. The limiting rack 510 meshes with the first gear 508.

[0056] A sealing cover 511 is provided at the lower opening of the weighing chamber 501. The sealing cover 511 is horizontally arranged. A first sealing groove 512 is provided in the housing 4 on both sides of the sealing cover 511. A second sealing groove 513 is provided on the side wall of the sealing cover 511 near the first sealing groove 512. The second sealing groove 513 is set as a semi-circular structure.

[0057] The third rotating shaft 514 is provided in the first closed groove 512. The third rotating shaft 514 is vertically arranged and rotatably connected to the housing 4. The lower end of the third rotating shaft 514 extends through to the outside of the housing 4, and a drive knob 515 is fixedly provided at the lower end of the third rotating shaft 514.

[0058] A sealing rod 516 is fixedly installed on the third rotating shaft 514. An abutment block 517 is fixedly installed at the upper end of the third rotating shaft 514. The sealing rod 516 is located between the abutment block 517 and the first sealing groove 512. When the sealing rod 516 rotates, it can extend into the second sealing groove 513.

[0059] The working principle and beneficial technical effects of the above technical solution are as follows: When the fixing component 5 is in use, after the wiring is connected and the box 1 is installed in the weighing cavity 501, the torsion spring 503 is set so that the straight edge of the first limiting block 504 initially faces the opening direction of the weighing cavity 501. When the box 1 is placed in, the box 1 abuts against the straight edge of the first limiting block 504, pushing the first limiting block 504 to rotate. When the first limiting block 504 rotates, it drives the first rotating shaft 502 to rotate, thereby driving the first sprocket 505 to rotate counterclockwise. The first sprocket 505 drives the second sprocket 507 to rotate through the chain drive, thereby driving the second rotating shaft. When the second shaft 506 rotates, it drives the first gear 508 to rotate, which in turn drives the limiting rack 510 to push out through meshing transmission, so that the limiting rack 510 abuts against the box body 1 and fixes the box body 1 by friction. At the same time, when the box body 1 is placed into the weighing chamber 501, the sealing cover 511 is closed. Then, the third shaft 514 is rotated by the drive knob 515. When the third shaft 514 rotates, it drives the sealing rod 516 to rotate, so that one end of the sealing rod 516 rotates into the second sealing groove 513, completing the fixation of the sealing cover 511 and supporting the box body 1 through the sealing cover 511.

[0060] In one embodiment, a friction block 518 is fixedly provided at one end of the limiting rack 510 near the weighing cavity 501, and the friction block 518 is made of rubber.

[0061] The working principle and beneficial technical effects of the above technical solution are as follows: By setting a friction block 518 made of rubber, the friction between the limiting rack 510 and the box 1 is increased, making the fixing effect of the limiting rack 510 on the box 1 more stable, thereby improving the stability of the device.

[0062] In one embodiment, a rotating plate 519 is fixedly disposed on the lower end surface of the drive knob 515, and the rotating plate 519 is vertically disposed.

[0063] The working principle and beneficial technical effects of the above technical solution are as follows: By setting the rotating plate 519, it is more convenient to rotate the drive knob 515 during use, which in turn facilitates the rotation of the third rotating shaft 514, thereby improving the practicality of the device.

[0078] The working principle and beneficial effects of the above technical solution are as follows: Compared with traditional electronic scales, the method of setting up a weighing module box inside makes the structure wrapped around the electronic components thicker, which is prone to heat generation. Therefore, a heat dissipation component 6 is required. When the heat dissipation component 6 is in use, the heat dissipation motor 605 starts and drives the fourth rotating shaft 606 to rotate, which in turn drives the cooling fan 607 to rotate for air cooling. The first filter plate 603 and the second filter plate 604 filter the incoming and outgoing air, filtering out dust and impurities. At the same time, when the fourth rotating shaft 606 rotates, it drives the drive wheel 614 to rotate. When the drive wheel 614 rotates, the drive plate 610 and the drive frame 608 move through the meshing of the drive gear 615 and the drive column 612. The movement trajectory is approximately elliptical. At this time, the cleaning brush 613 set on the side wall of the drive plate 610 moves with the drive plate 610 and brushes off the dust remaining on the surface of the first filter plate 603. The dust falls between the two collection plates 633 below, avoiding a large amount of dust remaining on the first filter plate. The surface of filter plate 603 affects the air permeability of the first filter plate 603. At this time, the second bevel gear 616 rotates with the fourth shaft 606. The second bevel gear 616 drives the third bevel gear 619 and the fifth shaft 618 to rotate through meshing transmission. When the fifth shaft 618 rotates, it drives the first crank 621 to rotate. At this time, the fifth bevel gear 625 revolves together with the first crank 621. At the same time, the fifth bevel gear 625 meshes with the fourth bevel gear 620 and rotates on its own axis. When the fifth bevel gear 625 rotates on its own axis, it drives the sixth shaft 606 to rotate. When the sixth bevel gear 626 rotates, it drives the seventh bevel gear 628 and the first protrusion 627 to rotate through meshing, which in turn drives the second crank 629 to rotate. At this time, the movement trajectory of the end of the second crank 629 and the second protrusion 630 is a straight line. The second protrusion 630 and the guide slider 631 move along a straight line, and drive the scraper 634 to move through the third crank 635, so as to collect the dust that falls between the collection plates 633 for easy collection and cleaning.

[0079] In one embodiment, a directional groove 636 is further provided on the bottom wall of the heat dissipation cavity 601.
