Embodiment 1

[0022] A telescopic test tube rack pusher device comprises a bracket cavity 5, a push handle assembly and a push plate 1, the bracket cavity is a cavity container with side openings, the push handle assembly is located in the bracket cavity, and the push plate is connected to the push handle assembly.

[0023] The push hand assembly includes a stepper motor 6, the output shaft of the stepper motor 6 is connected with a lead screw 9 through a coupling 8, and the lead screw 9 is provided with two slider nuts 7, and the thread between the lead screw 9 and the slider nut 7 connection, the rotation of the lead screw drives the slider nut to move along the lead screw, the two slider nuts rotate in the opposite direction and the pitch is equal, and the two slider nuts 7 are respectively connected to one end of an active connecting rod 4, and the two active connecting rods 4 are in the The position pin between the two ends is connected, and the other end of the active link is connected...

Embodiment 2

[0026] A telescopic test tube rack pusher device, the structure of which is as described in Embodiment 1, the difference is that two slider nuts 7 are respectively connected to one end of an active connecting rod 4, and the other ends of the two active connecting rods 4 are respectively Two passive connecting rods 13 are hinged, the active connecting rod is connected with the push plate through the passive connecting rod, and the two passive connecting rods are connected with each other through the pin 3, which can realize the 360° rotation of the connecting rod through the pin. Increasing the number of connecting rods facilitates increasing the moving distance of the push plate. The two active connecting rods are pinned at the midpoint, and the two passive connecting rods are pinned at the midpoint, so as to facilitate the control of the rotation angle and extension displacement of the connecting rods.

Embodiment 3

[0028] A telescopic test tube rack push handle device, the structure of which is as described in Embodiment 2, the difference is that the side of the push plate is provided with a boss 11, and the boss 11 is provided with a through groove 12 that runs through the upper and lower surfaces, and the through groove 12 is provided with a Sliding bolt 2 is arranged, and two passive connecting rods 13 are respectively connected with sliding bolt 2 by bolt, and the relative rotation of connecting rod can drive sliding bolt to move in the through groove, further increases the extension distance of push plate.

Abstract

The invention relates to a telescopic test-tube rack pusher device, and belongs to the technical field of medical detection devices. The device comprises a bracket cavity, a pusher assembly and a pushplate. The bracket cavity is a cavity container with a side opening; the pusher assembly is located in the bracket cavity; the push plate is connected with the pusher assembly; the pusher assembly comprises a stepping motor, an output shaft of which is connected to a lead screw through a coupling; the lead screw is provided with two slider nuts; the lead screw rotates to drive the slider nuts tomove along the lead screw; the two slider nuts have opposite directions of rotation but equal screw pitch; the two slider nuts are respectively connected to one end of an active connecting rod; and the two active connecting rods are in pin connection between the two ends, and the other ends of the active connecting rods are connected to the push plate. The stepping motor drives the lead screw to rotate, the two slider nuts move in a straight line to drive the connecting rods to rotate along with each other or rotate in the opposite directions. Thereby, the push plate is driven to move, and thetest-tube rack filled with the detected blood component can be pushed from the internal transfer track to the external return track at a time.

Description

Technical field [0001] The invention relates to a telescopic test tube rack pusher device and belongs to the technical field of medical detection devices. Background technique [0002] At present, single-machine operation of clinical medical inspections is stressful and inefficient. Therefore, fully automatic coagulation lines are widely used to solve the problem of coagulation testing in one stop. The problem is that when the blood components to be tested are completed on a sample arm of a certain instrument in the fully automatic coagulation line, and there is no need for the next test, they cannot be pushed from the inner transport track to the outer return path at the same time as the test tube rack. track. The existing test tube rack pusher can only push the test tube rack to the inner transport track. If you try to push the test tube rack to the outer track, there will be problems such as insufficient stroke and mechanism interference, which will reduce the detection ...
