Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to an electronic scale weighing pan structure. Background Art

[0002] An electronic scale is a weighing device based on electronic technology. It can accurately measure objects through sensors and display the results in digital form. When weighing objects using an electronic scale, a weighing pan is required to lift the objects.

[0003] Chinese patent CN219757506U discloses an electronic scale weighing pan structure. When encountering an object whose overall length exceeds the length of the weighing pan, the electronic scale weighing pan structure can pull out the extended weighing plates from both sides of the weighing pan to extend its overall length, thereby preventing the object from hanging on both sides of the weighing pan. At the same time, the magnetic attraction component restricts the traction of the side plates to prevent the extended weighing plate from moving during weighing. However, while solving the problem, this electronic scale weighing pan structure has the following drawbacks:

[0004] When the expansion board moves out from the inside of the weighing plate, the expansion plate is mainly limited by the magnetic component. Since the weighing plate is used on an electronic scale and the magnetic component is magnetic, this setting will affect the sensor, resulting in inaccurate weighing and affecting the battery life. When the electronic scale is used to weigh items, the setting of the magnetic component can easily lead to inaccurate weighing results. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] To this end, one purpose of the present invention is to propose an electronic scale weighing pan structure, which aims to solve the problem in the prior art that the setting of the magnetic suction component of the electronic scale weighing pan structure when the electronic scale weighs the items easily makes the weighing results of the electronic scale inaccurate.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides an electronic scale weighing pan structure, including an electronic scale, a weighing pan is provided on the top of the electronic scale, a storage slot is provided inside the weighing pan, a first expansion frame and a second expansion frame are movably connected inside the storage slot, a limiting tooth groove is provided on the front of the first expansion frame, a through groove is provided on the front of the weighing pan, a storage box is fixedly connected to one side of the through groove, a screw is rotatably connected to the front of the storage box, a fixed tooth block is rotatably connected to the bottom end of the screw, and the fixed tooth block is movably connected to the storage box.

[0008] Preferably, any of the above schemes is that the first expansion frame and the second expansion frame are fixedly connected to opposite sides with racks, a gear is engaged between the two racks, and the gear is rotatably connected to the storage slot. When the first expansion frame is pulled, the first expansion frame can drive the gear to rotate through the rack, so that the gear drives the second expansion frame to move through the rack on the other side, so that when moving the two expansion frames out from the inside of the storage slot, only one of the expansion frames needs to be pulled.

[0009] Preferably, any of the above schemes is that a limiting groove is provided at the bottom of the inner wall of the storage groove, the limiting groove is movably connected to a limiting block inside, the limiting block is fixedly connected to the rack, and when the rack moves inside the limiting groove, it can drive the limiting block to move inside the limiting groove, and the cooperation between the limiting groove and the limiting block can make it difficult for the expansion frame to detach from the weighing plate.

[0010] Preferably, any of the above schemes is that the bottom of the first expansion frame and the second expansion frame are both provided with rollers, and when the first expansion tray and the second expansion tray move inside the storage slot, the rollers can contact the inner wall of the storage slot and rotate. This setting design makes it relatively smooth when the two expansion trays are moved out of the interior of the storage slot.

[0011] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0012] 1. The fixed tooth block can be moved under the drive of the screw and meshed with the limit tooth groove, so that the expansion frame will not move arbitrarily after moving to the appropriate position. At the same time, the fixed tooth block, screw and limit tooth groove are non-magnetic, so that the data displayed by the electronic scale when weighing items is relatively accurate.

[0013] 2. By setting the rack, gear and roller, when moving the two expansion frames out of the storage slot, only one of the expansion frames needs to be pulled, and the expansion frames are moved smoothly, making the entire operation more convenient and labor-saving.

DETAILED DESCRIPTION

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] like Figure 1-6As shown, an electronic scale weighing plate structure of the present embodiment includes an electronic scale 1, a weighing plate 2 is provided on the top of the electronic scale 1, a storage slot 3 is provided inside the weighing plate 2, and a first expansion frame 4 and a second expansion frame 5 are movably connected inside the storage slot 3. When the width of the symmetrical plate 2 as a whole needs to be adjusted, the first expansion frame 4 and the second expansion frame 5 are directly pulled so that the two expansion frames can be moved inside the storage rack 3, and the overall length of the weighing plate 2 can be adjusted. A limiting tooth groove 6 is provided on the front of the first expansion frame 4, and the weighing plate 2 can be adjusted. A through slot 7 is provided on the front, and a storage box 8 is fixedly connected to one side of the through slot 7. The front of the storage box 8 is rotatably connected to a screw rod 9, and the bottom end of the screw rod 9 is rotatably connected to a fixed tooth block 10. The screw rod 9 is connected to the fixed tooth block 10 through a bearing, and the fixed tooth block 10 is movably connected to the storage box 8. When the expansion frame is moved to a suitable position, the screw rod 9 is directly rotated so that the screw rod 9 pushes the fixed tooth block 10 to move inside the storage box 8 and pass through the through slot 7, and then engages with the limiting tooth groove 6 to complete the fixation of the expansion frame.

[0026] Example 1: The first expansion frame 4 and the second expansion frame 5 are fixedly connected to the opposite side with a rack 11, and a gear 12 is engaged between the two racks 11. The gear 12 is rotatably connected to the storage slot 3. The gear 12 is connected to the storage slot 3 through a bearing. When the expansion frame is moved, the first expansion frame 4 is directly pulled so that the first expansion frame 4 drives the gear 12 to rotate through the rack 11, and the gear 12 drives the second expansion frame 5 to move through the rack 11 on the other side, so that the two expansion frames can be moved out of the inside of the storage slot 3 synchronously.

[0027] Example 2: A guide groove 13 is provided at the top of the second expansion frame 5, and the rack 11 on the first expansion frame 4 is movably connected to the guide groove 13. The guide groove 13 on the second expansion frame 5 can accommodate the rack 11 on the first expansion frame 4. When the first expansion frame 4 moves, it can drive the rack to move inside the guide groove 13. At the same time, the setting of the first expansion frame 4 is consistent with that of the second expansion frame 5.

[0028] Example 3: A limiting groove 14 is opened at the bottom of the inner wall of the storage slot 3, and the limiting block 15 is movably connected inside the limiting groove 14. The limiting block 15 is fixedly connected to the rack 11. When the expansion frame drives the rack 11 to move, the rack 11 can drive the limiting block 15 to move inside the limiting groove 14.

[0029] Example 4: A roller 16 is provided at the bottom of the first expansion frame 4 and the second expansion frame 5. The two expansion frames are in contact with the inner wall of the storage slot 3 through the roller 16. When the two expansion frames move, the roller 16 can be driven to rotate on the inner wall of the storage slot 3.

[0030] Example 5: The other end of the screw 9 is fixedly connected to a control disk 17 , and an anti-slip groove 18 is provided on the outer side of the control disk 17 , so that the screw 9 can be rotated more conveniently through the control disk 17 .

[0031] Example 6: A connecting chassis 19 is provided on the top of the electronic scale 1, a slot 20 is opened on the top of the connecting chassis 19, and an insert plate 21 is fixedly connected to the bottom of the weighing pan 2. The insert plate 21 at the bottom of the weighing pan 2 is directly inserted into the interior of the slot 20 and the weighing pan 2 is connected to the connecting chassis 19.

[0032] The working principle of the present invention is as follows: when in use, when the overall length of the symmetrical disk 2 is adjusted, the screw 9 is first rotated through the control disk 17, so that the screw 9 drives the fixed tooth block 11 to move to the inside of the storage box 8. At this time, the first expansion frame 4 is directly pulled, so that the first expansion frame 4 drives the gear 12 to rotate through the rack 11, and the gear 12 drives the second expansion frame 5 to move synchronously through another rack 11. When the two expansion frames are moved to the appropriate positions, the screw 9 is driven again through the control disk 17, so that the screw 9 pushes the fixed tooth block 10 and makes the fixed tooth block 10 engage with the limiting tooth groove 6, so that the fixed tooth block 10 cooperates with the limiting tooth groove 6 to complete the fixation of the expansion plate.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. When the first expansion frame 4 and the second expansion frame 5 are moved out from the inside of the storage slot 3, the screw 9 is directly rotated by the control disk 17, so that the screw 9 drives the fixed tooth block 10 to move to one side of the storage box 8 and the fixed tooth block 10 is no longer engaged with the limiting tooth groove 6. At this time, the two expansion frames are directly pulled. When the two expansion frames move to the appropriate positions, the screw 9 is rotated again by the control disk 17 and the screw 9 pushes the fixed tooth block 10, so that the fixed tooth block 10 is engaged with the limiting tooth groove 6 and the position of the expansion frame is limited. In summary, when the expansion frame is limited and fixed, it is mainly fixed by engaging the limiting tooth groove 6 with the fixed tooth block 10, and both are non-magnetic, so that the electronic scale 1 displays data more accurately when weighing the items through the weighing pan 2.

[0035] 2. When moving the two expansion frames out of the storage slot 3, the first expansion frame 4 is directly pulled, so that the rack 11 on the first expansion frame 4 drives the gear 12 to rotate, and the gear 12 drives the second expansion frame 5 to move synchronously through another rack 11. At the same time, the bottoms of the two expansion frames are in contact with the inner wall of the storage slot 3 through the roller 16, so that the roller 16 will rotate when the two expansion frames move. In summary, when moving the two expansion frames out of the storage slot 3, only one of the expansion frames needs to be pulled, and the expansion frames are relatively smooth when moving, and the entire operation is relatively convenient and labor-saving.
