Description

Technical Field

[0001] This solution relates to the technical field of weighing, and in particular to a weighing support. Background Technology

[0002] In electronic balance applications, some slender samples exceed the standard weighing pan dimensions. Additionally, some samples have irregular shapes, making it difficult to secure them on the weighing pan during weighing, with parts of the sample dangling off the pan. This results in long weighing stabilization times and poor repeatability. In particular, for high-precision balances, to achieve better weighing results and repeatability, the sample must be completely placed on the weighing pan, and its position and angle must be constrained to reduce errors caused by uncertainties in sample placement. Summary of the Invention

[0003] One of the technical problems this solution aims to solve is that slender samples are inconvenient to measure and the measurement results have poor repeatability.

[0004] To address the aforementioned technical problems, this embodiment provides a weighing support, which includes a connecting base and a plurality of support slots connected to the connecting base. The connecting base can be connected to an electronic balance, and the plurality of support slots are arranged at intervals in the horizontal direction to support slender samples. The plurality of support slots are symmetrically arranged about the center of gravity of the connecting base.

[0006] In some embodiments, the support slots are the same size in the arrangement direction, and the adjacent support slots on either side of the connecting base are spaced at the same interval.

[0007] In some embodiments, the spacing of the support grooves is the same as the dimension of the support grooves in the arrangement direction.

[0008] In some embodiments, the distance between the center of gravity of the connecting base and the nearest support groove is equal to the dimension of the support groove in the arrangement direction.

[0009] In some embodiments, the cross-section of the support groove is V-shaped.

[0010] In some embodiments, the connecting base includes a connecting rod with a threaded structure, which can be screwed onto the electronic balance.

[0011] In some embodiments, the connecting base further includes a support plate disposed on the top of the connecting rod, the support plate being symmetrically arranged about the center of gravity of the connecting base.

[0012] In some embodiments, the connecting base further includes an adapter that can be connected to the connecting rod.

[0028] refer to Figures 1-3 As shown, this solution provides a weighing support, which includes a connecting base 1 and a plurality of support slots 2 connected to the connecting base 1. The connecting base 1 can be connected to an electronic balance, and the plurality of support slots 2 are arranged at intervals in the horizontal direction to support slender samples. The plurality of support slots 2 are symmetrically arranged about the center of gravity of the connecting base 1.

[0029] The connecting base 1 can be connected to an electronic balance to achieve relative fixation between the weighing support and the electronic balance, ensuring the stability of the weighing support relative to the electronic balance.

[0030] Multiple support grooves 2 are arranged at intervals along a specific direction to jointly support the slender sample. The arrangement direction of the support grooves 2 corresponds to the horizontal direction, that is, when the weighing support is installed on the electronic balance, the multiple support grooves 2 extend horizontally.

[0031] In addition, the multiple support grooves 2 are symmetrical about the center of gravity of the connecting base 1, and the overall center of gravity of the multiple support grooves 2 coincides with the center of gravity of the connecting base 1, so as to avoid eccentricity and affect the measurement results.

[0032] In this design, multiple support grooves can support slender samples, ensuring their stability and thus improving measurement accuracy and ensuring the repeatability of measurement results.

[0033] In some embodiments, the weighing support further includes a support arm 4 extending along the arrangement direction of the support grooves 2, with multiple support grooves 2 disposed on the support arm 4. The support arm 4 can be connected to the connecting base 1 and connect the multiple support grooves 2. The support arm 4 can be symmetrically arranged about the center of gravity of the connecting base 1.

[0034] In some embodiments, the support grooves 2 have the same dimensions in the arrangement direction, and the spacing between adjacent support grooves 2 on either side of the connecting base 1 is the same. The identical dimensions of the support grooves 2, with a row of support grooves 2 provided on each side of the connecting base 1 and the same spacing between adjacent support grooves 2, help determine the dimensions of slender samples. Specifically, ensuring that the dimensions of the slender sample are substantially the same on both sides of the connecting base 1 ensures that the center of gravity of the slender sample is substantially aligned with the center of gravity of the connecting base 1, avoiding eccentricity that could affect the measurement results.

[0035] In some embodiments, the spacing of the support grooves 2 is the same as the dimension of the support grooves 2 in the arrangement direction. The support arms 4 between the support grooves 2 are the same size. Therefore, the support grooves 2 and the support arms 4 can be used as measurement references. By referring to the support grooves 2 and the support arms 4, the lengths of the portions on both sides of the connecting base 1 of the slender sample can be made to be substantially the same, so that the center of gravity of the slender sample is substantially coincident with the center of gravity of the connecting base 1, avoiding eccentricity that would affect the measurement results.

[0036] In some embodiments, the distance between the center of gravity of the connecting base 1 and the nearest support groove 2 is equal to the dimension of the support groove 2 in the arrangement direction. That is, the support arm 4 between the center of gravity of the connecting base 1 and the adjacent support groove 2 has the same dimension as the support groove 2, and multiple parts (support arm 4 and support groove 2) of the same size are formed in the arrangement direction of the support grooves 2 to facilitate the determination of the size of the slender sample as a reference.

[0037] In some embodiments, the cross-section of the support groove 2 is V-shaped. The support groove 2 forms a V-shaped support space, which can therefore be used to accommodate slender samples of different sizes. That is, for slender samples within a certain range of cross-sectional dimensions, they can be stably supported in the support groove 2. The support groove 2 can restrict their lateral movement and ensure the stability of the measurement.

[0038] In some embodiments, the connecting base 1 includes a threaded connecting rod 3, which can be screwed onto the electronic balance. The connecting rod 3 has external threads or threaded holes on its outer periphery for screwing onto the electronic balance, achieving a stable connection between the weighing support and the electronic balance. The connecting rod 3 is cylindrical in shape and extends vertically to connect to the electronic balance, ensuring that its central axis coincides with the center of gravity.

[0039] In some embodiments, the connecting base 1 further includes a support plate 5 disposed on the top of the connecting rod 3, the support plate 5 being symmetrically arranged about the center of gravity of the connecting base 1. The support plate 5 can be used to support calibration weights, and setting calibration weights on the support plate 5 allows for testing of the weighing support to determine whether the measuring structure of the weighing support is accurate.

[0040] In some embodiments, the connecting base 1 further includes an adapter that can be connected to the connecting rod 3. The connecting rod 3 can be connected to different types of electronic balances via the adapter. One end of the adapter can form a threaded hole or threaded rod that is screwed into the connecting rod 3, and the other end can be a structure adapted to different types of electronic balances, such as a threaded rod structure with different outer diameters.

[0041] In some embodiments, the weighing stand is made of metal. For example, it can be made of stainless steel, aluminum alloy, etc.
