Description
Technical field
The utility model relates to technical field of medical instruments, specifically a kind of mechanical type electric reaction tube grabbing device.
Background technology
Along with the development of society, the problem of people to healthy aspect and disease treatment aspect is more and more paid attention to, and how to carry out checking and appraising accurately to health and becomes the decisive foundation weighing health status and diagnoses and treatment.
In diagnostic mode, in-vitro diagnosis is diagnostic means important at present, and be the quantitative detection for disease association trace materials in human body, the diagnosis and treatment especially for diseases such as serious infectious diseases, cancer, diabetes are extremely important.
For sample analyser, it is the application of sample realized by the space displacement of reaction tube in detection, reagent adding, mixing, the processes such as cleaning and detection, it is one of effective way realizing efficient detection, and reaction tube handgrip is the critical component realizing its space movement, with regard to the reaction tube gripping structure of current structure, it normally adopts mechanical gripper components, then motor or other drive units is aided with, promote the folding of gripper components, and then the crawl of realization response pipe and release, although the crawl achieving reaction tube that the reaction tube gripper components of this structure is good and release.
But along with going deep into of design research and development, present inventor finds, current reaction tube handgrip still also exists defect, be embodied in the structure of its grippers, current grippers normally comprises multiple handgrip, drive unit is by driving each handgrip, and then the crawl work of realization response pipe, in current structure, the relation that the drive end of multiple handgrip normally cooperatively interacts, in order to realize the coordination of each handgrip, the structure that cooperative end part needs design complicated, while increasing manufacturing cost, also make troubles to follow-up maintenance, and, the situation that the as easy as rolling off a log appearance of cooperative end part is interfered mutually, when mutually interfering generation, easily there is mutually locked situation in each handgrip, also the crawl work making reaction tube is not reliably.
Based on above-mentioned, current reaction tube gripping structure is complicated, the crawl work completing reaction tube that can not be safe and reliable, so, need one at present badly and namely there is simple structure, reduce and manufacture maintenance cost, reliably can capture again the reaction tube grabbing device of reaction tube.
Summary of the invention
The purpose of this utility model is: the problems referred to above existed for prior art, provides the mechanical type electric reaction tube grabbing device that a kind of structure is simple, grasping stability, reliability are high.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of mechanical type electric reaction tube grabbing device, comprise installing rack, for capturing grippers and the drive unit of reaction tube, described grippers comprises at least two jaws, on described drive unit, be provided with corresponding with described jaw pushes away post, push away post described in corresponding one of jaw described in each, push away post described in described drive unit passes through and drive described grippers.
In the such scheme of the application, corresponding one of each jaw pushes away post, that is, between jaw, there is not the drive end cooperatively interacted, each jaw is relatively independent, is first a simplified structure, reduce manufacturing cost, and, also avoid the generation mutually interfered between each jaw, ensure the reliability of reaction tube crawl work.
As the preferred version of the application, described jaw rotates and is arranged on described installing rack, and described jaw is crawl arm along its rotating shaft side, and opposite side is pusher arm, push away post described in described drive unit passes through and promote described pusher arm, enable described jaw around each self-corresponding axis of rotation.By driving each jaw to rotate, realize the folding of grippers.
As the preferred version of the application, described drive unit comprises linear stepping motor, described in push away post and be arranged on the displacement output shaft of linear stepping motor, and be positioned at the side near each self-corresponding pusher arm.
In the such scheme of the application, be set directly on the displacement output shaft of linear stepping motor by pushing away post, first be the structure further simplifying the application's reaction tube grabbing device, simultaneously, the side of close each self-corresponding crawl arm is arranged on owing to pushing away post, that is, make it possible to arrange enough by pusher arm short, and, push away post more near the rotating shaft of jaw, so, first the distance between pusher arm is increased, avoid the generation interfered further, time even more important, owing to pushing away post more near the rotating shaft of jaw, that is the arm of force pushed away between post and rotating shaft is shortened, make when linear stepping motor provides identical displacement, the swing that crawl arm will produce by a larger margin, so, the displacement output quantity that linear stepping motor provides can be reduced, reduce the installing space of clamping device.
As another preferred version of the application, described drive unit comprises linear stepping motor, and the displacement output shaft of described linear stepping motor is provided with push rod, described in push away post and be arranged on described push rod, and be positioned at the side near each self-corresponding pusher arm.
