Utility Model Content

[0004] The purpose of this utility model is to provide a foldable electronic platform scale to solve the problem that in the prior art, the overall height of the foldable electronic platform scale is still relatively large when the square upright is folded to the upper surface of the platform.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable electronic platform scale includes a base, a connecting arm fixedly connected to the top of the side end of the base, a first folding arm rotatably connected to the end of the connecting arm, a second folding arm rotatably connected to the end of the first folding arm, a square upright rotatably connected to the end of the second folding arm, a support base detachably connected to the side end of the base, the support base being used to support the first folding arm, the second folding arm and the square upright, and a limit stop fixedly connected to the top of the connecting arm, the limit stop being used to limit the second folding arm.

[0007] Preferably, a display is installed at the top of the square pole, and a support leg is fixedly connected to the back of the display.

[0008] Preferably, the end of the limiting block is provided with a blocking surface, which limits the second folding arm by contacting the front part of the second folding arm.

[0009] Preferably, the top surface of the support base is provided with a support surface, and the top of the support base is provided with a limiting surface. The support surface limits the first folding arm by contacting its back. The limiting surface simultaneously contacts the back of the second folding arm and the square upright, thus limiting both of them.

[0010] Preferably, a threaded rod is rotatably connected to the surface of the support base, and the threaded section of the threaded rod extends out of the side of the support base. The corresponding side of the base is provided with a threaded groove for threaded connection of the threaded rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution.

[0025] A foldable electronic platform scale includes a base 1. A connecting arm 2 is fixedly connected to the top of the side of the base 1. A first folding arm 3 is rotatably connected to the end of the connecting arm 2. A second folding arm 4 is rotatably connected to the end of the first folding arm 3. A square upright 6 is rotatably connected to the end of the second folding arm 4. By rotating the upright 6, when the square upright 6 is folded into the lower part of the base 1, the display 7 faces upward. The display 7 is mounted on the top of the square upright 6. A support foot 8 is fixedly connected to the back of the display 7. By providing the support foot 8, when the square upright 6 is folded and the display 7 faces upward, the support foot 8 supports the ground, providing support for the display 7. The support is provided by a detachable support seat 12 on the side of the base 1. The support seat 12 is used to support the first folding arm 3, the second folding arm 4 and the square upright 6. When the first folding arm 3 and the second folding arm 4 are unfolded to make the square upright 6 vertical, the support seat 12 is installed to provide rear support for the first folding arm 3, the second folding arm 4 and the square upright 6 to prevent rotation. The top of the connecting arm 2 is fixedly connected to a limit stop 10. The limit stop 10 is used to limit the second folding arm 4. When the first folding arm 3 and the second folding arm 4 are unfolded to make the square upright 6 vertical, the limit stop 10 blocks the second folding arm 4 to limit it and prevent the second folding arm 4 from tilting forward further.

[0026] Please refer to Figure 7By setting the first folding arm 3 and the second folding arm 4, the support base 12 can be disassembled, and then the first folding arm 3 and the second folding arm 4 can be flipped downwards, so that the square upright 6 can be rotated to the lower part of the base 1 for folding. The lower space of the base 1 can be reasonably utilized. The height of the support of the base 1 can be selected in the lower space of the base 1 in a conventional way to make it compatible with the square upright 6. As needed, after folding, it is optional to install the support base 12 on the base 1.

[0027] The end of the limiting block 10 is provided with a blocking surface 11, which limits the second folding arm 4 by contacting the front part of the second folding arm 4.

[0028] The top surface of the support base 12 is provided with a support surface 13, and the top of the support base 12 is provided with a limiting surface 14. The support surface 13 limits the first folding arm 3 by contacting its back. The limiting surface 14 simultaneously contacts the back of the second folding arm 4 and the square upright 6, limiting both of them. The support surface 13 can support the first folding arm 3 to prevent it from flipping downwards, and the limiting surface 14 can support the second folding arm 4 to prevent it from flipping downwards. At the same time, it can support the square upright 6 to prevent it from rotating.

[0029] A threaded rod 15 is rotatably connected to the surface of the support base 12, and the threaded section of the threaded rod 15 extends out of the side of the support base 12. The corresponding side of the base 1 is provided with a threaded groove for threaded connection of the threaded rod 15.

[0030] The bottom end of the square upright 6 is fixedly connected to a T-shaped rotating shaft 5, and the top end of the second folding arm 4 is provided with a T-shaped circular groove for the T-shaped rotating shaft 5 to rotate.

[0031] It also includes a weighing platform 9, which is mounted on top of the base 1.

[0032] The specific steps are as follows: If the equipment is in a folded state and the support base 12 is already installed, first rotate the threaded rod 15 on the surface of the support base 12 to unscrew it from the threaded groove on the side of the base 1. Remove the support base 12 and set it aside. Hold the square upright 6 and flip the first folding arm 3 and the second folding arm 4 upwards until the square upright 6 is in a vertical position. Observe that the front part of the second folding arm 4 contacts the blocking surface 11 of the limiting block 10. At this time, the first folding arm 3 and the second folding arm 4 have been unfolded to the limiting position. Then rotate the square upright 6 so that the display 7 faces forward. Align the support base 12 with the installation position on the side of the base 1, and rotate the threaded rod 15 to screw it into the threaded groove of the base 1. This completes the installation of the support base 12. Confirm that the supporting surface 13 of the support base 12 contacts the back of the first folding arm 3, and the limiting surface 14 contacts the back of the second folding arm 4 and the square upright 6. Ensure that all components are stable and do not wobble. At this time, the weighing platform 9 is located on top of the base 1, the display 7 is in a vertical position, and the equipment can be used normally.

[0033] When folding is required, rotate the threaded rod 15 on the support base 12 to disengage it from the threaded groove of the base 1, remove the support base 12, hold the square upright 6, and rotate it in the T-shaped groove of the second folding arm 4 through the T-shaped rotating shaft 5 to adjust the orientation of the monitor 7. Flip the first folding arm 3 and the second folding arm 4 downwards to gradually move the square upright 6 towards the lower part of the base 1. Continue flipping until the square upright 6 is completely retracted into the lower part of the base 1. At this time, the monitor 7 is facing upwards, and the support foot 8 is in contact with the ground and supports the monitor 7. If needed, the support base 12 can be reinstalled on the base 1 to complete the folding operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
