[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1-5 , an electronic balance storage box that can be used as a verification auxiliary platform, comprising:

[0050] A storage box 1 is an open-top structure for storing an electronic balance. A cover 2 is provided on the top of the storage box 1 to cover the open box and close the storage box 1. One end of the cover 2 is hinged to one side of the top of the storage box 1. The cover 2 is swung open and closed by one end of the cover 2. The cover 2 can be opened and rotated from a closed state to a horizontal state through a hinge to be used as a platform for placing tools.

[0051] The verification auxiliary platform structure is rotatably arranged inside the storage box 1, wherein the verification auxiliary platform structure rotates from a vertical state to a horizontal state inside the storage box 1 to serve as an auxiliary platform for electronic balance verification, wherein the vertical state inside the storage box 1 of the verification auxiliary platform structure is the state in which the verification auxiliary platform structure is stored inside the storage box 1;

[0052] A support mechanism is provided on one side of the storage box 1 to support the box cover 2 and the verification auxiliary platform structure rotated to a horizontal state and keep them in a horizontal state, that is, when the box cover 2 and the verification auxiliary platform structure are kept in a horizontal state, the box cover 2 and the bottom surface of the verification auxiliary platform structure are located on the same horizontal plane and are kept in a horizontal state by the support of the support mechanism; and

[0053] The electronic balance fixing mechanism is used to fix the electronic balance inside the storage box 1 to stably maintain the storage of the electronic balance.

[0054] Furthermore, the verification auxiliary platform structure includes:

[0055] The coverless box body 3 has one end hingedly connected to the top position of one side of the storage box body 1;

[0056] An adjustment plate 4, which is arranged inside the uncovered box body 3 and used as an auxiliary platform for electronic balance calibration; and

[0057] The leveling mechanism is arranged between the leveling plate 4 and the uncovered box body 3 to support the leveling plate 4 and adjust the leveling plate 4 to a horizontal state.

[0058] Specifically, the coverless box body 3 is used to install the adjustment plate 4 and the leveling mechanism, and the adjustment plate 4 is supported by the leveling mechanism and adjusted to a horizontal state, so that the adjustment plate 4 is used as a calibration platform to assist the electronic balance in performing calibration work. The deployment and use of the calibration auxiliary platform structure and the leveling work of the adjustment plate 4 are simple and convenient, thereby improving the efficiency of the electronic balance calibration work.

[0059] Furthermore, the hinged side of the uncovered box body 3 in the storage box body 1 is opposite to the hinged side of the box cover 2 on the storage box body 1, so that when the uncovered box body 3 and the box cover 2 are both rotated to a horizontal state, the two can be compactly located on the same horizontal plane, and the uncovered box body 3 and the box cover 2 in adjacent positions can be simultaneously supported by the support mechanism to remain in a horizontal state.

[0060] Further, the leveling mechanism comprises:

[0061] A universal shaft 5 is arranged between the center of the leveling plate 4 and the center of the inner bottom surface of the uncovered box body 3; and

[0062] The leveling movable support leg structure comprises four groups of identical structures and are respectively arranged at four corners of the leveling plate 4 and located inside the uncovered box body 3 .

[0063] Specifically, the universal joint 5 is supported at the center position of the leveling plate 4, so that the leveling plate 4 can be adjusted to a horizontal state by adjusting the height of the four corners. Specifically, the support height of the four corners of the leveling plate 4 is adjusted by the leveling movable support foot structure, so that the leveling plate 4 can be adjusted to a horizontal state.

[0064] Furthermore, the leveling movable leg structure includes:

[0065] A leveling movable plate 6 is arranged below the leveling plate 4. A threaded hole 7 is provided at the center of the leveling movable plate 6. A guide hole 8 is provided beside the threaded hole 7 on the leveling movable plate 6.

[0066] The threaded rod 9 has a lower end rotatably connected to the inner bottom surface of the coverless box body 3 through a bearing, and an upper end passes through the threaded hole 7 and is threadedly engaged with the threaded hole 7. A nut 10 is provided on the upper end surface of the threaded rod 9;

[0067] A guide rod 11, the lower end of which is vertically fixedly connected to the inner bottom surface of the uncovered box body 3, and the upper end of which passes through the guide hole 8 and slides in the guide hole 8; and

[0068] The avoidance notch 12 is provided on the leveling plate 4 to avoid the threaded rod 9 from extending upward and to support the leveling movable plate 6 below the leveling plate 4 .

[0069] Specifically, during operation, the threaded rod 9 is rotated by rotating the nut 10. Because the leveling movable plate 6 guides the guide rod 11 to slide in the guide hole 8, and the leveling movable plate 6 cannot rotate axially relative to the threaded rod 9, the threaded rod 9 and the threaded hole 7 on the leveling movable plate 6 are threadedly matched to drive the leveling movable plate 6 to move axially relative to the threaded rod 9 to adjust the height of one of the corners of the leveling movable plate 4 supported by the leveling movable plate 6. The remaining three corner positions are adjusted in this way until the leveling plate 4 is adjusted to be horizontal.

[0070] Furthermore, a level meter 13 is embedded on the upper surface of the leveling plate 4, and whether the level meter 13 is adjusted to a horizontal state is observed.

[0071] Furthermore, the supporting mechanism includes:

[0072] Two mounting holes 14 are provided on the side surface of the storage box 1 and are located at the same horizontal position; and

[0073] Two support rods 15 having the same structure and corresponding to the two mounting holes 14 one by one, and the support rods 15 are inserted into the corresponding mounting holes 14; and

[0074] The limiting plates 16 are symmetrically arranged in two groups on both sides of the storage box 1 , and each group of limiting plates 16 is connected between two support rods 15 .

[0075] Specifically, the support rod 15 is installed in the mounting hole 14. When not in use, the support rod 15 is completely inserted into the storage box 1 for storage and hiding. When in use, after the support box cover 2 and the uncovered box body 3 are rotated to a horizontal state, the support rod 15 is moved so that the two ends of the support rod 15 are respectively supported on the support box cover 2 and the uncovered box body 3. The limiting plate 16 not only connects the two support rods 15, but also prevents the support rod 15 from being separated from the mounting hole 14.

[0076] Furthermore, the mounting hole 14 is located on the side of the storage box body 1 where the box cover 2 on the storage box body 1 is hinged so as to support the box cover 2 and the uncovered box body 3 at the same time.

[0077] Further, the electronic balance fixing mechanism comprises:

[0078] The coverless storage box 17 is a coverless box structure;

[0079] A horizontal rod 18 is provided on one side of the uncovered storage box 17 and moves horizontally and axially relative to the uncovered storage box 17;

[0080] A first top plate 19, which is disposed on one end of the horizontal rod 18 and located inside the uncovered storage box 17;

[0081] A second top plate 20 disposed on one end of the horizontal rod 18 outside the uncovered storage box 17; and

[0082] The first compression spring 21 is sleeved on the horizontal rod 18 and compressed between the first top plate 19 and the inner wall of the uncovered storage box 17 .

[0083] Furthermore, a second compression spring 22 is horizontally arranged on the inner surface of the uncovered storage box 17 opposite to the side where the horizontal rod 18 is located, and the end of the second compression spring 22 is connected to the third top plate 23 .

[0084] Specifically, the uncovered storage box 17 can also be used to place weights for electronic balance calibration. After placing the weight box loaded with weights, the weight box is clamped between the first top plate 19 and the third top plate 23 under the simultaneous action of the first compression spring 21 and the second compression spring 22. When the first top plate 19 and the third top plate 23 are made of anti-slip materials, the weight box can be well prevented from separating from the uncovered storage box 17. At this time, the uncovered storage box 17 and the electronic balance are placed in the storage box 1, and the verification auxiliary platform structure is in a vertical state stored in the storage box 1. At this time, the electronic balance is clamped between the verification auxiliary platform structure and the second top plate 20 on the uncovered storage box 17. After placing the weight box, because the first compression spring 21 and the second compression spring 22 are in a compressed state at the same time, and the electronic balance is placed in, the first compression spring 21 and the second compression spring 22 are in a balanced state. The elastic compression of the first compression spring 21 will push the second top plate 20 through the horizontal rod 18, so that the second top plate 20 pushes the electronic balance, and the electronic balance is clamped between the second top plate 20 and the verification auxiliary platform structure. Realize stable storage of electronic balances.

[0085] To sum up, the device can be used to load the weights for electronic balance and electronic balance calibration work at ordinary times. When the electronic balance calibration work needs to be carried out, the calibration auxiliary platform structure can provide a horizontal surface for the electronic balance calibration work to assist the calibration work of the electronic balance, which greatly improves the flexibility of the calibration work and avoids the work troubles caused thereby.

[0086] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
