Technical Field

[0001] The utility model relates to the technical field of food inspection weighing, and particularly relates to a food inspection weighing fixing device. Background Technique

[0002] In the field of food inspection, accurate weighing is one of the key steps to ensure the reliability of test results. However, in the actual operation process, there are often some containers, such as centrifuge tubes, test tubes, etc., whose bottoms are designed to be conical or circular, making it difficult for these containers to be stably placed on the tray of the balance. During the weighing process, the containers are prone to tilt or slide, which not only affects the accuracy of weighing but also poses a risk of sample spillage due to tilting. Therefore, we have proposed a food inspection weighing fixing device. Content of the Utility Model

The upper support cylinder is detachably installed at the upper end of the lower support base through the four connecting screws. Two positioning members are arranged inside the upper support cylinder, and the two positioning members are distributed vertically.

[0006] Four connecting blocks are integrally formed at the lower end of the upper support cylinder, and the four connecting blocks are arranged in a circular array.

The upper support cylinder 1 is detachably installed at the upper end of the lower support base 2 through the four connecting screws 3. Two positioning members 5 are arranged inside the upper support cylinder 1, and the two positioning members 5 are distributed vertically.

[0031] In this embodiment, four connecting blocks 11 are integrally formed at the lower end of the upper support cylinder 1, and the four connecting blocks 11 are arranged in a circular array. Two clamping strips 12 are integrally formed on the outer surface of the connecting block 11, and a positioning hole 13 is arranged in the middle of the outer surface of the connecting block 11; four connecting grooves 21 adapted to the size of the connecting blocks 11 are arranged on the outer surface of the lower support base 2. Two clamping grooves 22 adapted to cooperate with the clamping strips 12 are arranged on the inner surface of the connecting groove 21, and a screw hole 23 corresponding to the position of the positioning hole 13 is arranged in the middle of the inner surface of the connecting groove 21; the connecting block 11 is slidably installed in the connecting groove 21 through the clamping strips 12 on both sides, and the connecting screw 3 passes through the positioning hole 13 and is threadedly connected to the screw hole 23 to fixedly install the connecting block 11 and the connecting groove 21.

[0032] Through the above solution: the upper support cylinder 1 is aligned with the connecting groove 21 on the lower support base 2 through the connecting block 11 at its lower end, and the clamping strips 12 on the connecting block 11 slide into the clamping grooves 22 in the connecting groove 21 to achieve preliminary positioning.
