Description

Technical Field

[0001] The utility model belongs to the technical field of clamps for assisting the preparation of oxygen, nitrogen and hydrogen samples, and more specifically, particularly relates to a clamp for assisting the preparation of oxygen, nitrogen and hydrogen samples. Background Art

[0002] The fixture used to assist in the preparation of oxygen, nitrogen and hydrogen samples generally refers to a tool or device used to fix, support or handle samples. During the preparation of oxygen, nitrogen and hydrogen samples, the fixture can help place the sample safely in the appropriate position for subsequent experimental operations.

[0003] Before testing the samples, the staff needs to preheat the samples and then send them to the testing instrument for testing. The existing fixtures require the staff to transport the samples to the heating equipment for preheating after preparing them, and then send them to the testing instrument for testing. After the test is completed, the container will be removed. After the previous sample test is completed, the staff needs to wait for the sample to be heated before the next test can be carried out, which greatly reduces the test efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fixture for assisting the preparation of oxygen, nitrogen and hydrogen samples is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0011] Furthermore, the number of the clamping grooves is equal to the number of through grooves, and a number of the through grooves are respectively located directly below a number of the clamping grooves.

[0012] Furthermore, the active intermittent gear is meshed with the driven intermittent gear.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By using the rotating block, the screw rod, the clamping block 2 and the clamping block 1 in coordination, firstly, several containers are placed in several through slots respectively, the bottoms of the containers pass through the through slots and are flush with the bottoms of the through slots, and then the rotating block is rotated, the rotating block drives the screw rod to rotate, and the screw rod drives the clamping block 2 to move in the direction of the clamping block 1 through rotation, so that the container can be clamped, thereby achieving the purpose of clamping containers of various sizes, thereby improving the use effect of the clamp.

[0015] Through the coordinated use of control buttons, motors, active intermittent gears, driven intermittent gears and heating blocks, turn on the heating block to preheat the samples in one group of containers. After the heating is completed, the staff will take out the containers and send them to the testing instrument for testing. When taking out the containers, the staff will press the control button, and the control button will control the motor to rotate one circle. The motor drives the active intermittent gear to rotate one circle, the active intermittent gear drives the driven intermittent gear to rotate 60°, the driven intermittent gear drives the placement table to rotate 60°, and the placement table drives several containers to rotate 60°, so that another container can be moved to the top of the heating block for preheating, so that the staff can preheat the next sample at the same time when testing the sample, which reduces waiting time and improves work efficiency.
