Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: test tube clamping device for physiology experiments, including mount pad 1 and anchor clamps 4, the fixed support column 3 that sets up in bottom of mount pad 1, driving shaft 2 is installed to 1 internal rotations of mount pad, the one end fixed connection of driving shaft 2 changes 14, the other end of driving shaft 2 runs through mount pad 1 and fixed connection anchor clamps 4, establish the cavity in the mount pad 1, install the locking mechanical system of restriction driving shaft 2 motion in the cavity, locking mechanical system includes hanger plate 5, ratchet 6, drive pawl 7 and pawl 8, the fixed top that sets up at mount pad 1 cavity of

hanger plate

5, 6 covers of ratchet are established on driving shaft 2, drive pawl 7 and pawl 8 just all are connected with the meshing of ratchet 6 about 2 mirror symmetry of driving shaft. Through setting up ratchet 6, drive pawl 7 and the locking claw 8 mating reaction under, can still have the function of auto-lock in driving shaft 2 can normal rotation for it can stably keep the inclination of anchor clamps 4, thereby can require according to the experiment to alternate test tube inclination, can satisfy the requirement of some special experiments.

As shown in fig. 2, a rectangular long groove is formed in the hanger plate 5, a return spring 12 and a slide block 11 are sequentially arranged in the rectangular long groove from top to bottom, one end of the return spring 12 is fixed at the top end of the inner wall of the hanger plate 5 and fixedly connected, the other end of the return spring 12 is fixedly connected with the slide block 11, the slide block 11 is in sliding fit with the rectangular long groove, the slide block 11 is integrally in an i-shaped structure, protruding blocks are fixedly connected to two sides of the slide block 11, and the driving pawl 7 and the stopping pawl 8 are hinged to a group.

As shown in fig. 2, a set of columns 9 is fixedly arranged in the middle of each of the driving pawl 7 and the stopping pawl 8, and an extension spring 10 is fixedly connected between the two sets of columns 9. By means of the tension spring 10, the drive pawl 7 and the holding pawl 8 are allowed to have a tendency to deflect inwardly, ensuring that the ratchet wheel 6 is stationary when the drive shaft 2 stops rotating.
