Description

Technical Field

[0001] This utility model relates to the field of electronic scales, and in particular to an electronic scale for auxiliary weighing. Background Technology

[0002] An electronic scale is a product used to weigh objects. However, it can be troublesome when weighing items with sharp bases that are difficult to place, especially on experimental containers such as test tubes and conical flasks with pointed bottoms. Therefore, when weighing items that need to be placed in these containers, it is generally necessary to weigh them first and then put them in. However, the disadvantage is that when the material is weighed and then put into the container, it is often impossible to transfer the material completely. There is often some residue that cannot be completely transferred into the container due to adhesion, which affects the accuracy. Moreover, during the weighing and transfer process, because the material is exposed outside the container for a long time, spillage often occurs. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an electronic scale that facilitates the weighing of containers that are difficult to place.

[0004] The technical solution adopted by this utility model to solve the problem is: an electronic scale for auxiliary weighing, including a scale body, a weighing plane and a connecting frame located behind the weighing plane on the scale body, and a control platform on the top of the connecting frame;

[0005] A support frame is pivotally connected to the connecting frame. The support frame can swing relative to the connecting frame to be positioned directly above the weighing plane. An auxiliary support position is provided on the support frame.

[0006] As a further improvement to the above technical solution, the support frame is plate-shaped, and the auxiliary support position is an auxiliary hole set on the support frame and extending through the top and bottom.

[0007] As a further improvement to the above technical solution, there are several auxiliary holes, and the size of each auxiliary hole is different.

[0008] As a further improvement to the above technical solution, all auxiliary holes are arranged in a ring on the support frame, and the size of the auxiliary holes gradually increases along the ring direction.

[0009] As a further improvement to the above technical solution, a through mounting hole is provided in the middle of the support frame, and an auxiliary plate is detachably arranged on the mounting hole, with all auxiliary holes arranged on the auxiliary plate.

[0010] As a further improvement to the above technical solution, a stepped surface is provided on the upper edge of the mounting hole, and an annular seat is formed by extending the top outer periphery of the auxiliary plate outward, with the annular seat receiving the stepped surface.

[0011] As a further improvement to the above technical solution, the upper surface of the support frame is provided with a slot located on the side of the stepped surface, and the edge of the annular seat is provided with a positioning protrusion extending outward and used to engage with the slot.

[0012] As a further improvement to the above technical solution, the edge of the mounting hole is connected to an extension hole, and when the auxiliary plate is installed into the mounting hole, the extension hole is located on the side of the auxiliary plate.

[0013] As a further improvement to the above technical solution, the support frame includes a main rod section pivotally connected to the connecting frame and a folding section pivotally connected to the main rod section. The folding section is formed by a number of segments pivotally connected in sequence. The included angle between two adjacent segments is between 90 and 170 degrees. When all segments are fully unfolded, they are located on the same horizontal plane and form a ring with a central angle of more than 180 degrees. The main rod section can swing and switch between horizontal and vertical states.

[0024] Reference Figures 1 to 3 An electronic scale for auxiliary weighing includes a scale body 10, on which a weighing plane is provided and a connecting frame 20 located behind the weighing plane, and a control platform is provided on the top of the connecting frame 20.

[0025] A support frame 30 is pivotally connected to the connecting frame 20. The support frame 30 can swing relative to the connecting frame 20 and is positioned directly above the weighing plane. An auxiliary support position is provided on the support frame 30.

[0026] During normal weighing, the support frame 30 is retracted, allowing for normal weighing of items. When it is necessary to weigh containers such as conical flasks or test tubes that are difficult to place at the bottom, the support frame 30 is unfolded and placed directly above the weighing plane. The auxiliary support positions on the support frame 30 support the container, making it convenient to weigh.

[0027] In this design, the support frame 30 is preferably plate-shaped, and the auxiliary support position is an auxiliary hole 31 disposed on the support frame 30 and extending through it from top to bottom. Considering the different sizes of the test tubes, it is preferable that there are several auxiliary holes 31, and each auxiliary hole 31 has a different size.

[0028] For further optimization and to ensure regularity, it is preferable that all auxiliary holes 31 are arranged in a ring on the support frame 30, and the size of the auxiliary holes 31 gradually increases along the ring direction.

[0029] Further optimization is preferred, with a through mounting hole 301 in the middle of the support frame 30. An auxiliary plate 32 is detachably arranged on the mounting hole 301, and the auxiliary holes 31 are all arranged on the auxiliary plate 32. This makes it convenient to clean the auxiliary plate 32, and the mounting hole 301 can serve as the largest auxiliary hole 31 to help fix the container.

[0030] Further optimization is preferred, with a stepped surface 33 provided on the upper edge of the mounting hole 301, and an annular seat extending outward from the top outer periphery of the auxiliary plate 32, which is supported on the stepped surface 33 to facilitate the placement of the auxiliary plate 32. In addition, the upper surface of the support frame 30 is preferably provided with a slot 34 located on the side of the stepped surface 33, and the edge of the annular seat is provided with a positioning protrusion 341 extending outward and used to engage with the slot 34 to facilitate positioning.

[0031] Further optimization is preferred, where the edge of the mounting hole 301 is connected to an extension hole 35. When the auxiliary plate 32 is installed into the mounting hole 301, the extension hole 35 is located on the side of the auxiliary plate 32, thereby facilitating the insertion of a finger from above the support frame 30 into the bottom of the auxiliary plate 32 through the extension hole 35, and thus making it easier to remove the auxiliary plate 32.

[0032] In this solution, the support frame 30 can be implemented in various ways. In a second embodiment, the support frame 30 includes a main rod section pivotally connected to the connecting frame 20 and a folding section pivotally connected to the main rod section. The folding section is formed by sequentially pivotally connecting several segments, with the included angle between two adjacent segments being between 90 and 170 degrees. When all segments are fully unfolded, they lie on the same horizontal plane and form a ring with a central angle exceeding 180 degrees. The main rod section can swing between a horizontal and a vertical state. Thus, in use, the main rod section is swung downwards to a horizontal state, and then all segments are fully unfolded to a horizontal plane, forming a ring structure with a central angle exceeding 180 degrees to facilitate the placement of containers. Preferably, the connecting frame 20 has a storage groove on its front side, the main rod section is pivotally connected to the storage groove, and the support frame 30 is located within the storage groove when fully folded.

[0033] In the third embodiment, the support frame 30 includes a movable block pivotally connected to the connecting frame 20 and capable of vertical swinging, and several collars pivotally connected to the movable block and capable of horizontal rotation. Each collar has a different size, and the corresponding collar can be screwed out according to the different size requirements during use.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
