DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] The utility model is a kind of experimental bottle tube clamp which can prevent tipping. Figure 1 As shown, it comprises a handle 1, one end of which is connected to a telescopic rod 5 through a rotating assembly, the end of the handle 1 connected to the telescopic rod 5 is connected to a blocking unit, the end of the telescopic rod 5 away from the handle 1 is connected to a clamping mechanism, and one side of the handle 1 is connected to a pressing handle 2, which is connected to the clamping mechanism through a pull rope 8. The clamping mechanism clamps the experimental bottle tube, and by pressing the pressing handle 2, the pressing handle 2 pulls the pull rope 8, and the pull rope 8 jumps and pulls the clamping mechanism, so as to clamp the experimental bottle tubes of different sizes and models, and the blocking unit prevents the telescopic rod 5 from rotating the entire shaft, that is, to prevent the experimental bottle tube from tipping over.

[0021] Example 1

[0022] like Figure 2 As shown, the blocking unit includes an adjustment ring 3, which is sleeved on the end of the handle 1, and the side of the adjustment ring 3 away from the handle 1 is connected to an adjustable block 4, and the rotating assembly is connected to a fixed block 7. The rod body of the telescopic rod 5 is connected to a positioning block 6, and the positioning block 6 is arranged between the adjustable block 4 and the fixed block 7, and the positioning block 6 is arranged close to the handle 1. During normal use, the adjustment ring 3 is adaptively rotated according to actual needs to keep an appropriate distance between the adjustable block 4 and the fixed block 7. The telescopic rod 5 is adaptively rotated at a certain angle under the action of gravity, and the adjustable block 4 and the fixed block 7 block the positioning block 6 to prevent the telescopic rod 5 from making a complete circular rotation, that is, to prevent the experimental bottle tube from tipping over.

[0023] The rotating assembly includes a bearing 14, the bearing 14 is connected to the handle 1, the end of the telescopic rod 5 is connected to the inner ring of the bearing 14, and the fixed stopper 7 is connected to the side of the bearing 14. The fixed stopper 7 is fixed relative to the handle 1, and the telescopic rod 5 can be flexibly rotated around the handle 1 through the setting of the bearing 14.

[0024] Example 2

[0025] like Figure 3 As shown, the clamping mechanism includes a positioning claw 12, one end of which is connected to the telescopic rod 5, and the end of the telescopic rod 5 connected to the positioning claw 12 is also connected to a dynamic clamping claw 11 through a rotating shaft 15, and the side wall of the dynamic clamping claw 11 is connected to one end of the pull rope 8 through a clamping spring 10, and the dynamic clamping claw 11 matches the positioning claw 12. The pull rope passes through the clamping spring 10 and is connected to the dynamic clamping claw 11. The positioning claw 12 and the dynamic clamping claw 11 are both semicircular structures. By pulling the pull rope 8, the dynamic clamping claw 11 can be pulled to rotate along the rotating shaft 15. The dynamic clamping claw 11 compresses the clamping spring 10 during the rotation process. Experimental tubes of different models and sizes are placed between the dynamic clamping claw 11 and the positioning claw 12. After the pull rope 8 is released, the clamping spring 10 is reset under the action of elastic force, and the dynamic clamping claw 11 is pushed to rotate in the opposite direction, so that the experimental tube can be clamped.

[0026] The end of the movable clamping jaw 11 is connected with a connecting ring 16, and the rotating shaft 15 is connected to the end of the telescopic rod 5, and the shaft body of the rotating shaft 15 is connected in the connecting ring 16. The connection between the connecting ring 16 and the rotating shaft 15 ensures that the movable clamping jaw 11 can rotate along the rotating shaft 15.

[0027] Example 3

[0028] The side wall of the movable clamping jaw 11 is connected with a connecting plate 17, which is arranged at the connection point between the movable clamping jaw 11 and the connecting ring 16. The plate surface of the connecting plate 17 is connected to one end of the clamping spring 10, and the pull rope 8 passes through the clamping spring 10 and is connected to the connecting plate 17. When the pull rope 8 is pulled, the movable clamping jaw 11 rotates, and the connecting plate 17 compresses the clamping spring 10. The clamping spring 10 pushes the connecting plate 17 during the resetting process, that is, pushes the movable clamping jaw 11 to rotate in the opposite direction.

[0029] The rod body of the telescopic rod 5 is connected with a fixing buckle 9, the side wall of the fixing buckle 9 is connected with a limiting plate 18, the pull rope 8 passes through the plate surface of the limiting plate 18, and the end of the clamping spring 10 away from the connecting plate 17 is connected to the limiting plate 18. The limiting plate 18 and the fixing buckle 9 are integrally formed, the limiting plate 18 limits the clamping spring 10, and cooperates with the connecting plate 17 to compress the clamping spring 10.

[0030] The inner walls of the positioning claw 12 and the moving clamping claw 11 are respectively connected with rubber sleeves 13 along their circumferential directions. The rubber sleeves 13 are designed in a toothed shape to increase the friction on the experimental bottle tube.

[0031] The working principle of the anti-dumping experimental bottle tube clamp of the utility model is as follows:

[0032] When moving the experimental bottle tube, the pressing handle 2 is pressed, and the pressing handle 2 pulls the connecting plate 17 through the pull rope 8, so that the movable clamping jaw 11 can be pulled to rotate along the rotating shaft 15. During the rotation of the movable clamping jaw 11, the connecting plate 17 and the limit plate 18 compress the clamping spring 10, and the experimental bottle tubes of different models and sizes are placed between the movable clamping jaw 11 and the positioning claw 12. After the pull rope 8 is released, the clamping spring 10 is reset under the action of elastic force, pushing the connecting plate 17, and the clamping jaw 11 rotates in the opposite direction to clamp the experimental bottle tube. The rotating adjustment ring 3 is adaptively rotated according to actual needs to keep an appropriate distance between the adjustable stop block 4 and the fixed stop block 7. The telescopic rod 5 adaptively rotates a certain angle under the action of gravity, and the adjustable stop block 4 and the fixed stop block 7 block the positioning block 6 to prevent the telescopic rod 5 from making a complete circular rotation, thereby preventing the experimental bottle tube from tipping over.

[0033] The utility model discloses an anti-dumping experimental bottle tube clamp, which can clamp test tubes and conical flasks of different types by adjusting the size of the clamping mechanism by pressing the handle. The length of the telescopic rod can be adjusted according to actual use to adapt to use. The setting of the bearing can meet the needs of the experimental bottle tube to adaptively tilt slightly by its own weight, and the blocking unit can also prevent the experimental bottle tube from dumping.
