Disclosure of Invention

In order to solve the technical problems, the invention provides a test tube clamping and releasing device which effectively solves the problem of space waste on the basis of ensuring the test tube inclination effect through a structure for clamping and inclining a test tube.

The invention is realized by the following technical scheme.

The ends of the two clamping rings are connected through an elastic structure.

The elastic structure is a spring, and more than two connecting ends are arranged on each connecting end.

The bottom of the operating ring is provided with a boss which protrudes transversely, and the fixing ring is arranged on the edge of the boss.

Also comprises a guy cable and a pulley block; the pull cable is sleeved in the pulley block, and two ends of the pull cable are connected to the far end of the transverse rod relative to the operating ring; one pulley in the pulley block can move.

The pulley block is characterized by further comprising an operating handle, and the operating handle is arranged on a movable pulley in the pulley block.

The invention has the beneficial effects that: by the structure of clamping and inclining the test tube, the problem of space waste is effectively solved on the basis of ensuring the inclination effect of the test tube, the operation is convenient, and the test tube can be simply pulled; simple structure and convenient maintenance.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

The test tube clamping and releasing device shown in fig. 1 comprises an operation ring 1, a clamping ring 2, a moving rod 23 and a transverse rod 3; the operating ring 1 is a vertically arranged cylindrical ring, and the edge of the bottom of the operating ring is oppositely provided with a fixing ring 11; the transverse rod 3 is horizontally arranged above the fixing ring 11; the moving rod 23 passes through the fixed ring 11 from the vertical direction; the clamping rings 2 are arc-shaped rings with an angle smaller than 180 degrees, the two clamping rings 2 are horizontally arranged oppositely, the two clamping rings 2 are respectively provided with a transverse rod 3 correspondingly, flat teeth 32 are arranged on the two transverse rods 3, and a half gear 33 meshed with the flat teeth 32 is arranged in the middle of each flat tooth 32; a pull ring 21 is arranged at the arc top of the clamping ring 2; the top end of the moving rod 23 is sleeved in a sleeve ring 31 at the end part of the transverse rod 3, and the bottom end is sleeved in the pull ring 21; the radian difference of the smooth surfaces of the half gears 33 corresponding to the two transverse rods 3 is 15-60 degrees.

The ends of the two clamping rings 2 are connected through an elastic structure.

The elastic structure is a spring 22, and more than two connecting ends are arranged.

The bottom of the operating ring 1 is provided with a lug boss 12 protruding transversely, and the fixing ring 11 is arranged at the edge of the lug boss 12.

Also comprises a guy cable 34 and a pulley block 35; the pull cable 34 is sleeved in the pulley block 35, and two ends of the pull cable are connected to the far end of the transverse rod 3 relative to the operating ring 1; one pulley in the pulley block 35 can move.

And the operating handle 36 is also included, and the operating handle 36 is arranged on a movable pulley in the pulley block 35.

When the test tube fixing device is used, only the test tube needs to be placed in the two clamping rings 2, and then the movable pulley in the pulley block 35 is pulled, the movable pulley in the pulley block 35 is pulled to enable the guy cable 34 to be tensioned, so that the transverse rod 3 is driven to move, the movable rod 23 is pulled to enable the clamping rings 2 to be tightened, and under the restriction of the half gear 33 corresponding to the transverse rod 3, one transverse rod 3 stops moving relative to the other transverse rod 3 early, so that the transverse rod 3 which moves continuously can enable the clamping rings 2 to incline, so that the test tube inclines, when the two transverse rods 3 stop moving under the restriction of the half gear 33, the movable pulley in the pulley block 35 can be fixed, and can be fixed through related equipment, and can also be fixed through the fixing operation handle 36.
