DETAILED DESCRIPTION

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Example 1, as Figure 1-4 As shown, the utility model provides a technical solution for a clamp for a centrifuge: it includes two clamp bodies 1, and a limiting convex plate 16 is fixed on one side of the two clamp bodies 1 near the rear edge. The two sides of the limiting convex plates 16 are opposite to each other. A back pad 2 is provided between the rear sides of the two clamp bodies 1, a front pressure plate 5 is provided between the front sides of the two clamp bodies 1, a bottom pressure plate 10 is installed between the bottoms of the two clamp bodies 1, and a top pressure plate 11 is installed between the tops of the two clamp bodies 1.

[0027] The effect achieved by the entire embodiment 1 is that, by fixing the limiting convex plate 16 on one side of the clamp body 1 near the rear edge, it is convenient to support and guide the back pad 2 when the back pad 2 is subsequently installed. By setting the back pad 2 and the front pressure plate 5, the base plate 15 can be constrained to prevent it from falling. If the size of the base plate 15 is close to the maximum value allowed by the clamp body 1, the back pad 2 and the front pressure plate 5 can be omitted, and only the bottom pressure plate 10 and the top pressure plate 11 can meet the use requirements.

[0028] Example 2, as Figure 1-4As shown, a base plate 15 is provided between the opposite sides of the two clamp bodies 1, the rear side of the base plate 15 is in contact with the front side of the back pad 2, and the front side of the base plate 15 is in contact with the rear side of the front pressure plate 5, and the two limiting protrusions 16 are extended to one side of the back pad 2, and the front pressure plate 5 and the back pad 2 are both provided with a waist-shaped groove 12, and a limiting bolt 8 is provided between the inner walls of the two waist-shaped grooves 12, and a locking nut 9 is provided on the rear side of the back pad 2, and the limiting bolt 8 is threadedly connected to the locking nut 9, and a front slide groove 13 is provided near the front edge of the two clamp bodies 1. The two front slide grooves 13 are both extended to the front side of the clamp body 1, and the inner walls on both sides of the two front slide grooves 13 are slidably connected. Two sliding nuts 7, butterfly bolts 6 are provided on the front side of the front pressure plate 5 near the edges on both sides, one end of the two butterfly bolts 6 extends to the inside of the front slide groove 13, and is correspondingly threadedly connected to the second sliding nut 7, the interior of the two clamp bodies 1 is provided with a back slide groove 14 near the rear edge, the two back slide grooves 14 pass through the rear side of the clamp body 1, and the first sliding nuts 4 are slidably connected between the inner walls on both sides of the two back slide grooves 14, and the rear sides of the two clamp bodies 1 are provided with knob bolts 3, one end of the two knob bolts 3 extends to the inside of the back slide groove 14, and is correspondingly threadedly connected to the first sliding nut 4, and the protruding parts of the two knob bolts 3 extend to the rear side of the back pad 2.

[0029] The effect achieved by the entire embodiment 2 is that the outer dimensions of the clamp body 1 are adapted to the centrifuge fixed seat, and a limit bolt 8 and a locking nut 9 are provided in the middle of the waist-shaped groove 12, so that the middle base plate 15 can be locked and adjusted. The front and rear sides of the clamp body 1 are fixed with the back pad 2 and the front pressure plate 5 respectively, which is suitable for a relatively small base plate 15 to prevent the base plate 15 from shaking too much when the centrifuge is used. The back pad 2 and the front pressure plate 5 are fixed and can be adjusted on the clamp body 1; because the clamp body 1 is provided with a front chute 13 and a back chute 14, a second sliding nut 7 and a first sliding nut 4 are provided inside it, and the front pressure plate 5 can be set to different sizes according to the thickness of the base plate 15. Because its thickness is relatively thin, it also has a certain elasticity; the back pad 2 is provided at the bottom of the clamp body 1 to prevent the base plate 15 from falling out, and the front pressure plate 5 is provided on the top of the clamp body 1 to prevent the base plate 15 from falling out. The butterfly bolt 6 is convenient for quick disassembly and assembly, and any other fasteners can also be replaced according to actual needs.

[0030] Working principle: By arranging a limit bolt 8 and a locking nut 9 inside the waist-shaped groove 12 in the middle, the middle base plate 15 can be locked and adjusted. The first sliding nut 4 is installed in the back slide groove 14 of the clamp body 1, and cooperates with the knob screw 3 to fix the back pad 2. The second sliding nut 7 is installed in the front slide groove 13 of the clamp body 1, and cooperates with the butterfly bolt 6 to fix the front pressure plate 5. It is suitable for base plates 15 with relatively small sizes. If the size of the base plate 15 is close to the maximum value allowed by the clamp body 1, the back pad 2 and the front pressure plate 5 can be omitted, and only the bottom pressure plate 10 and the top pressure plate 11 can meet the usage requirements.
