Problems solved by technology

[0011] The object of the present invention is to provide a device capable of reducing the size of the drive device in view of the short service life of the current reaction tube grasping device due to the excessive wear intensity between the drive device and the gripper and the inability to reliably grasp the reaction tube. Abrasion strength between the gripper and the service life is improved, and the reaction tube grabbing device that can reliably grab the reaction tube

Embodiment 1

[0070] Example 1, such as Figure 1-5 as shown,

[0071] A gripper for a reaction tube grasping device, the gripper 1 has a clamping end 11 matched with the reaction tube, and a driving part 12 matched with the driving device 2, the driving device 2 drives The driving part 12 of the gripper 1 enables the gripper 1 to realize the cooperation or separation of the clamping end 11 and the reaction tube. A device 3 , the rotating device 3 forms a rolling friction fit with the driving part 12 and / or the driving device 2 of the gripper 1 .

[0072] In the above scheme of the present application, a rotating device 3 is provided between the driving part 12 of the gripper 1 and the driving device 2, and the rotating device 3 forms a rolling friction fit with the driving part 12 of the gripper 1 and / or the driving device 2, so that , the gripper of the present application, in the process of being driven, the driving device 2 first drives the rotating device 3, and the rotating device 3...

Embodiment 2

[0074] Example 2, such as Figure 1-5 as shown,

[0075] As in the gripper 1 shown in Embodiment 1, the gripper 1 also has a mounting portion 13, and the mounting portion 13 and the clamping end 11 of the gripper 1 are respectively two of the gripper 1 along the length direction. end, the driving part 12 is arranged between the mounting part 13 and the clamping end 11, when the driving device 2 drives the driving part 12, the gripper 1 can rotate around its mounting part 13, The rotating device 3 is arranged on the driving part 12 of the gripper 1, the rotating device 3 is a bearing, the outer ring of the bearing is matched with the driving device 2, and the driving part 12 of the gripper 1 A pin shaft 15 is arranged on it, and the bearing is arranged on the driving part 12 of the gripper 1 through the pin shaft 15, and the pin shaft 15 and the driving part 12 of the gripper 1 are connected in rotation, The pin shaft 15 can rotate around its own axis, the inner ring of the b...

Embodiment 3

[0077] Example 3, such as Figure 1-5 as shown,

[0078] A reaction tube grasping device, which includes at least the gripper 1 as described in embodiment 1 or 2, at least two clamping ends 11 of the grippers 1 cooperate to form a clamp for clamping the reaction tube Holding part 4.

[0079] The reaction tube grasping device of the above scheme of this embodiment uses at least two grippers 1 to cooperate to clamp the reaction tube. Since a bearing is provided between the gripper 1 and the driving device 2, the response of the application is improved. The service life of the tube gripping device and the reliability when gripping the reaction tube.

Abstract

The invention relates to the technical field of medical instruments, in particular to tongs, a reaction tube gripping device and an analysis instrument. The tongs are provided with a clamping end matched with a reaction tube and a driving part matched with a driving device; the driving device drives the driving part of the tongs to enable the clamping end to be matched with or be separated from the reaction tube through the tongs; and a rotating device is further arranged between the driving part of the tongs and the driving device and is in rolling friction fit with the driving part of the tongs and / or the driving device. By means of the tongs, the abrasion strength between the driving device and the tongs is reduced, the service life of the reaction tube gripping device is prolonged, and the reaction tube can be reliably gripped.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gripper, a reaction tube gripping device and an analyzer. Background technique [0002] With the development of society, people pay more and more attention to the problems of physical health and disease treatment. How to accurately diagnose and evaluate the physical condition has become the decisive basis for measuring health status and diagnosis and treatment. [0003] Among the diagnostic methods, in vitro diagnosis is currently an important diagnostic method, which is aimed at the quantitative detection of disease-related trace substances in the human body, especially for the diagnosis and treatment of major infectious diseases, cancer, diabetes and other diseases. [0004] For the sample analyzer, the process of adding sample, adding reagent, mixing, cleaning and testing in the detection is realized through the spatial displacement of the reaction tube, which is one...
