[0002] Electronic price computing scales are precision measuring tools widely used in commercial transactions and industrial measurement. They utilize load cells and an eight-bit single-chip microprocessor, ensuring accurate and rapid weighing and pricing. Not only are they easy to use, but they also feature a waterproof keyboard, a good seal, and a comfortable feel, making them particularly suitable for measuring and purchasing aquatic products. Using electronic price computing scales allows businesses to efficiently weigh and calculate prices, improving transaction efficiency and accuracy while also providing consumers with a fair and transparent shopping environment.

[0003] Although electronic pricing scales play a vital role in the transaction process, there are still some problems that need to be solved in actual use. Since electronic pricing scales are often exposed to various complex environments, such as dust and water vapor, their accuracy and lifespan are often affected. In addition, the existing electronic pricing scale protective covers are usually large in size, which not only takes up space but is also inconvenient to carry and store when not in use. Utility Model Content

[0004] In order to overcome the disadvantage of being inconvenient to carry, the technical problem is: to provide a portable protective cover for protecting an electronic price computing scale.

DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Embodiment: A portable protective cover for an electronic price computing scale, such as Figures 1-4As shown, it includes a top plate 1, a rotating plate 2, a side plate 9, a connecting plate 91 and a locking assembly. The left and right sides of the top plate 1 are connected to the connecting plates 91. The lower end of the connecting plate 91 is rotatably connected to the side plates 9. The front and rear sides of the top plate 1 are rotatably connected to the rotating plate 2. The top plate 1, the rotating plate 2 and the side plates 9 form a box body, which is used to cover the electronic scale 14. The thickness of the rotating plate 2 is less than the width of the connecting plate 91 to ensure that the connecting plate 91 can complete a 90-degree rotation. The distance between the two side plates 9 is greater than the length of the rotating plate 2 to ensure that the rotating plate 2 will not get stuck on the side plates 9. Locking assemblies for stabilizing the box body are provided in the rotating plate 2 and the side plates 9.

[0020] like Figure 3 and Figure 4 As shown, the locking assembly includes a fixed hook 3, a limit block 4, an elastic member 5, a connecting rod 6 and a cross bar 7. Three fixed hooks 3 are connected to the rotating plate 2, and a cross bar 7 is slidably connected to the side plate 9, and an unlocking slot 8 is opened on the side plate 9. The cross bar 7 is exposed outside the side plate 9 through the unlocking slot 8. Connecting rods 6 are connected at both ends of the cross bar 7. The connecting rod 6 is slidably connected to the side plate 9. Three limit blocks 4 are connected to the connecting rod 6, and each limit block 4 is limited and matched with the fixed hook 3. An elastic member 5 is provided in the side plate 9. The upper end of the elastic member 5 is connected to the limit block 4, and the lower end is connected to the side plate 9. A groove is opened on the inner side of the side plate 9, and the groove corresponds to the fixed hook 3 connected to the rotating plate 2. The limit block 4 is provided with an inclined surface on the side close to the electronic scale 14. The fixed hook 3 is squeezed and matched with the inclined surface of the limit block 4. The sliding stroke of the cross bar 7 is greater than the height of the limit block 4.

[0021] When the user needs to use the electronic scale 14, he takes out the electronic scale 14, folds the protective cover, holds the horizontal bar 7 and pulls it downwards. Since the horizontal bar 7 is connected to the limit block 4 through the connecting rod 6, this action will cause the limit block 4 to slide in the side plate 9 and compress the elastic member 5 at the same time. The horizontal bar 7 is continuously pulled until the limit block 4 is completely separated from the fixed hook 3 on the rotating plate 2. Since the rotating plate 2 and the top plate 1 are rotatably connected, the rotating plates 2 at both ends can be pushed toward the middle and flipped until the rotating plate 2 and the top plate 1 are in the same plane. When rotating the rotating plate 2, the horizontal bar 7 is released, the elastic member 5 is reset, and the horizontal bar 7 is pushed. , the connecting rod 6 and the limit block 4 are reset upward, and then the side panels 9 on both sides are pushed toward the middle. During the rotation of the side panels 9, the fixed hooks 3 are aligned with the grooves on the inner sides of the side panels 9, thereby offsetting the influence of the fixed hooks 3 on the thickness of the rotating plate 2, and the thickness of the rotating plate 2 is less than the width of the connecting plate 91, so the rotating plate 2 can fit with the side panels 9 to complete the folding. After folding, it is inverted on a plane. Since the top plate 1, the rotating plate 2 and the side panels 9 fit together, they have sufficient load-bearing capacity. The electronic scale 14 can be placed on the side panels 9, thereby solving the problem that the protective cover is inconvenient to place or takes up space when idle;

[0022] When the cover needs to be used, the side panels 9 are unfolded downward until the side panels 9 stand vertically on the ground, and then the rotating plate 2 is also flipped downward to form a complete box structure. During this period, the fixed hook 3 of the rotating plate 2 is squeezed by the inclined surface of the limit block 4, and the squeezed limit block 4 slides downward, compressing the elastic member 5 while driving the cross bar 7 and the connecting rod 6 to slide downward. When the fixed hook 3 completely passes through the inclined surface of the limit block 4, the elastic member 5 rebounds, and the limit block 4, cross bar 7 and connecting rod 6 slide back to their original position, and the limit block 4 and the side panels 9 clamp the fixed hook 3, thereby limiting the rotating plate 2. The two sides of the rotating plate 2 are against the side panels 9, thereby forming a stable box structure, which is covered on the electronic scale 14 to ensure the environment of the electronic scale 14.

[0023] like Figure 1 As shown, it also includes an anti-skid pad 10, and the exposed middle part of the cross bar 7 is covered with the anti-skid pad 10.

[0024] When the horizontal bar 7 is moved, the anti-slip pad 10 can increase the friction between the hand and the horizontal bar 7 to prevent slipping.

[0025] like Figure 1 As shown, it also includes a threaded rod 11 , the rotating plate 2 is threadedly connected with the threaded rod 11 , and the electronic scale 14 is provided with a threaded hole at a position corresponding to the threaded rod 11 .

[0026] The threaded rod 11 is screwed into the threaded hole at the bottom of the electronic scale 14 to further fix the position of the electronic scale 14 in the protective cover.

[0027] like Figure 2 As shown, it also includes a handle 12. The top of the top plate 1 is rotatably connected to the handle 12, and a placement groove is opened on the top plate 1. The handle 12 can be placed in the placement groove to ensure that the top surface of the top plate 1 is flat.

[0028] The handle 12 is flipped up from the placement slot, and the entire protective cover is lifted up for carrying or storage. The electronic scale 14 can be moved together with the threaded rod 11.

[0029] like Figure 2 As shown, it also includes support legs 13, and the two ends of the top of the top plate 1 are rotatably connected to the support legs 13.

[0030] After the protective cover is folded, the support legs 13 are rotated and unfolded, and the support legs 13 are in contact with the placement surface, thereby protecting the surface quality of the top plate 1.

[0031] By gripping and operating the horizontal bar 7, the user can easily unlock and fold the rotating plate 2 and the side panels 9 by utilizing its cooperation mechanism with the limit block 4 and the elastic member 5. In the unlocked state, the rotating plate 2 can be flipped toward the center to be parallel to the top plate 1, and the side panels 9 can also be folded toward the center until the entire protective cover forms a compact flat structure that is convenient for storage and carrying. At this point, the top plate 1, the rotating plate 2, and the side panels 9 fit together to form a solid and flat load-bearing surface, on which the electronic scale 14 can be placed directly. When the protective cover is needed, the user unfolds the folded side panels 9 and the rotating plate 2 separately, so that they are reassembled into a complete box structure. During the unfolding process, the fixed hook 3 on the rotating plate 2 interacts with the inclined surface of the limit block 4 in the side panel 9, so that the limit block 4 automatically resets and clamps the fixed hook 3 under the action of the elastic member 5, thereby firmly locking the position of the rotating plate 2 and the side panel 9, ensuring the stability and protection of the box. In addition, the anti-slip pad 10 improves the stability of operation, the threaded rod 11 provides an additional fixing method for the electronic scale, the handle 12 makes it convenient for users to carry the entire protective cover, and the support feet 13 can protect the top plate from damage when the protective cover is folded.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
