Description of the drawings
The clamp arm unfolding state figure of one embodiment of Fig. 1 the utility model；
The state diagram that the clamp arm of one embodiment of Fig. 2 the utility model clamps；
One embodiment overall structure schematic diagram of Fig. 3 the utility model.
Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of turnable grasping mechanism of lever connecting rod, including guide rod 1, guide sleeve 2, bottom plate 3, clamp arm 4, connecting rod 5 and holder
6, the guide rod 1 is slidably connected with fixed block 2, and the guide sleeve 2 is set on bottom plate 3, and the first notch is opened up on the bottom plate 3
31, the clamp arm 4 is L-shaped, and one end and connecting rod 5 are hinged, and the other end opens up the second notch 41,3 turns of corner and bottom plate
It is dynamic to connect, it is provided with connector 63, clamping cylinder 62 and fixed block 61 on the holder 6, the guide sleeve 2 is set to fixed block 61
In, the connector 63 is set to the rod end of clamping cylinder 62 and is connect with one end of guide rod 1.
As shown in Figure 1, the first notch 31 and the second notch 41 are used cooperatively, make the test tube 9 tested and be held in the first slot
In mouth 31 and the second notch 41, guide rod 1, guide sleeve 2, bottom plate 3, clamp arm 4 and connecting rod 5 form link mechanism, pass through clamping cylinder
The effects of 62 push-and-pulls, make guide rod 1 be slided up and down relative to guide sleeve 2, to make the rotation of clamp arm 4 opposed bottom 3 clamp test tube 9.
Clamp arm 4 is L-type, plays the effect of lever, gripping strength is prevented to reduce the pulling force from cylinder as a laborious lever
Too senior general's test tube 9 is caught broken.The stability of clamping is increased, effectively instead of manual clamping by the connecting rod lever mechanism of machinery
It prevents from scalding caused by being clamped by hand and broken danger is effectively reduced the clamping force of cylinder, prevented by laborious lever
Because of the excessive damage test tube of chucking power.
Grasping mechanism may be reversed in the lever connecting rod, and 5 each two pieces of clamp arm 4 and connecting rod is symmetrical to be set to bottom plate 3
On.
As shown in Figure 1, 2, the clamp arm 4 of the left and right sides coordinates bottom plate 3 that two test tubes 9 are clamped in the left and right sides respectively,
Two test tubes 9 can be simultaneously clamped on by the effect of a clamping cylinder 62, it is easy to use.
