Description
TECHNICAL FIELD
[0001] The utility model relates to sample tube automatic cap removal technical field, concretely relates to a five hole cap removal clamping arm structure. BACKGROUND
[0002] Sample tube cap removal refers to the process of automatically or manually removing the cap of a sealed sample tube (such as a vacuum blood collection tube) during an experiment or medical procedure. This process is crucial for subsequent sample processing and analysis.
[0003] Clamping the test tube during the sample tube cap removal process is an important step, which is crucial for quickly and effectively removing the cap. Therefore, the utility model designs a five hole cap removal clamping arm structure. SUMMARY
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a five hole cap removal clamping arm structure that can effectively tighten the clamping action of the test tube, ensure its clamping effect, has high stability, smooth movement, high efficiency, and strong practicality.
[0005] To achieve the above-mentioned purpose, the utility model is implemented by the following technical solutions: a five hole cap removal clamping arm structure includes a five hole cap removal clamping inclined arm and a five hole cap removal clamping PTFE shaft sleeve. The five hole cap removal clamping inclined arm is symmetrically provided with a short shaft hole at both ends, and a short shaft is installed in the short shaft hole through the five hole cap removal clamping PTFE shaft sleeve. A center hole is provided at the center of the five hole cap removal clamping inclined arm, and a five hole cap removal clamping swing shaft penetrates the center hole.
[0006] As a preferred embodiment, the five hole cap removal clamping inclined arm is provided with multiple.
[0007] As a preferred embodiment, the short shaft is fixedly connected with the five hole cap removal single tube clamping block combination single tube clamping block.
[0008] The utility model has the advantages of:
[0009] The PTFE shaft sleeve has good wear resistance, which can effectively reduce the wear between the inclined arm and the hole, prolonging the service life. The PTFE material has self-lubricating properties, which can reduce friction without external lubrication, ensuring smooth movement. It has good corrosion resistance, simple and fast installation process, reducing assembly time and cost. The PTFE shaft sleeve can absorb part of the vibration and noise, improving the stability and quietness of the system. Due to the self-lubricating properties and durability of the PTFE shaft sleeve, the daily maintenance requirement is less, reducing the maintenance cost. BRIEF DESCRIPTION OF DRAWINGS
[0010] The utility model will be described in detail below in combination with the drawings and specific embodiments;
