[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0026] Example: Please refer to Figure 1-7 A supermarket electronic scale includes a scale body 1 and a printing paper outlet 18. The scale body 1 is provided with a key panel 11, a tray 12 and a display panel 13. The display panel 13 is connected to the scale body 1 through a connecting rod. The existing technology can be used. The display panel 13 can display information such as price and weight. The scale body 1 is provided with a handle 14, which is rotatably connected to both sides of the scale body 1. The handle 14 is convenient for lifting the supermarket electronic scale to move.
[0027] The scale body 1 is provided with a cover plate 15 at the printing paper outlet 18, the left end of the cover plate 15 is rotatably connected to the scale body 1, and the right end of the cover plate 15 is not connected to the scale body 1. The scale body 1 is provided with a limiting member 17 on the right side of the right end of the cover plate 15, and the limiting member 17 includes a limiting block 171, a second spring 172, a connecting column 174 and a pulling block 173. The scale body 1 is provided with a first groove and a second groove respectively matched with the limiting block 171 and the pulling block 173, the connecting column 174 passes through the part of the scale body 1 between the first groove and the second groove and is gap-matched with the part of the scale body 1, and the two ends of the connecting column 174 are respectively fixedly connected with the limiting block 171 and the pulling block 173. The two ends of the second spring 172 are respectively fixedly connected with the inner wall of the first groove and the limiting block 171. When the pulling block 173 is pulled, the limiting block 171 compresses the second spring 172 so that the limiting block 171 retracts into the first groove, which facilitates the right end of the cover plate 15 to pass through. The pull block 173 is provided with a pull ring 1731, which is convenient for fingers to hold and pull. Two connecting columns 174 are provided, and three second springs 172 are provided, making the structure more stable. The limiting block 171 and the pull block 173 are respectively provided with limit blocks, and correspondingly, the first groove and the second groove are respectively provided with limit grooves. The limit blocks and the limit grooves cooperate so that the limiting block 171 and the pull block 173 can move linearly in the first groove and the second groove respectively to prevent shaking. The cover plate 15 is provided with a third groove that cooperates with the limiting block 171. When the cover plate 15 is in a closed state, the limiting block 171 enters the third groove to limit the cover plate 15 to prevent the cover plate 15 from rotating.
[0028] The scale body 1 is provided with a pop-up member 19 at the right end facing the cover 15, which is used to pop out the cover 15. The pop-up member 19 includes a first spring 191 and a round cover 192. The scale body 1 is provided with a fourth groove for accommodating the pop-up member 19, and the two ends of the first spring 191 are fixedly connected to the inner wall of the fourth groove and the round cover 192 respectively. There are two pop-up members 19, which enhances the pop-up effect. A protrusion 193 is provided on the round cover 192, and a fifth groove cooperating with the protrusion 193 is provided in the fourth groove to prevent the round cover 192 from shaking during movement. When the limiting block 171 retracts into the first groove, the pop-up member 19 directly pops out the cover 15, making it convenient to open the cover 15; when the cover 15 is in a closed state, the first spring 191 in the pop-up member 19 is compressed to store force.
[0029] The cover 15 is provided with a magnet 151, and the scale body 1 is provided with a magnet 2 16. The magnet 2 16 is located at a position where the right end of the cover 15 contacts or is close to the scale body 1 when the cover 15 is in an open state. The cover 15 in an open state can be fixed by the magnet 151 and the magnet 2 16.
[0030] Working principle of this embodiment: This embodiment provides a supermarket electronic scale, by pulling the pull ring 1731 on the limiting member 17 to retract the limiting block 171 into the first groove, closing the cover 15, the pop-up member 19 is compressed when the cover 15 is closed, then releasing the pull ring 1731 to allow the limiting block 171 to enter the third groove on the cover 15 under the action of the second spring 172 to limit the cover 15 and prevent the cover 15 from rotating, when it is necessary to open the cover 15, pull the pull ring 1731, the cover 15 pops up under the action of the pop-up member 19, release the pull ring 1731, and then rotate the cover 15 to the extent that the magnet 1 151 and the magnet 2 16 generate suction, so as to fix the cover 15 in the open state. The supermarket electronic scale uses the cover 15 to cover the printing paper outlet 18, and limits the cover 15 to be in a closed state through the limiting member 17, so as to prevent dust in the outside air from entering the inside of the electronic scale from the printing paper outlet 18.
