DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-3 shown, a horizontal rotor for a centrifuge includes a rotor disc 1 and a hanging basket. Support blocks 101 are evenly arranged on the side wall of the rotor disc 1. Inclined hanging grooves 102 are provided on both side walls of the support block 101. The upper end of the hanging groove 102 faces inwards, and the bottom of the hanging groove 102 faces outwards. The hanging basket includes a tube 2. A hanging block 201 is provided on the side wall of the tube 2. The hanging block 201 is located between two support blocks 101. A rotating shaft 202 matched with the hanging groove 102 is provided on the side wall of the hanging block 201. The end of the rotating shaft 202 is close to the side wall of the hanging groove 102, which can prevent the hanging basket from shaking left and right. A tray 205 for supporting the centrifuge tube 3 is connected to the lower end of the tube 2. Positioning blocks 4 for clamping the centrifuge tube 3 are provided on the inner wall of the tube 2. The number of the positioning blocks 4 is two and they are arranged oppositely. The positioning blocks 4 are in sliding fit with the centrifuge tube 3. The positioning blocks 4 can expand and contract according to the diameter of the centrifuge tube 3, so as to realize the clamping of different centrifuge tubes 3.

[0026] As Figures 4-5 shown, a sliding hole 206 is provided on the inner wall of the tube 2. A limiting groove 207 is provided on the inner wall of the sliding hole 206. The positioning block 4 is in sliding fit with the sliding hole 206. A limiting block 402 matched with the limiting groove 207 is provided on the side wall of the positioning block 4. A spring 5 is connected between the bottom of the sliding hole 206 and the positioning block 4.

[0027] As Figure 6 shown, the upper end surface of the positioning block 4 is an inclined structure, and the end of the positioning block 4 for clamping the centrifuge tube 3 is an inner concave structure. When the centrifuge tube 3 is inserted into the tube 2, it can push the positioning block 4 away along the inclined surface of the positioning block 4. The lower end of the centrifuge tube 3 abuts against the upper end of the tray 205. Under the action of the spring 5, the positioning block 4 clamps and fixes the centrifuge tube 3.

[0028] An installation hole 401 for fixing the spring is provided on the side wall of the positioning block 4, which can increase the length of the spring 5 and improve the stability of the spring at the same time.

[0029] The wall thickness of the tube 2 is not less than the length of the positioning block 4.

[0030] In order to increase the smoothness of the insertion of the centrifuge tube 3, a fillet is provided at the upper end of the end of the positioning block 4 for clamping the centrifuge tube 3.

[0031] The upper end of the support plate 205 is connected to a pull plate 204. The pull plate 204 is inserted into the tube 2. A locking bolt 203 for fixing the pull plate 204 is provided on the side wall of the tube 2, which can adjust the distance between the support plate 205 and the tube 2 according to the length of different centrifuge tubes 3, and improve the stability of fixing the centrifuge tube 3.

[0032] The diameter of the support plate 205 is not less than the inner diameter of the tube 2, which increases the stability of the support for the tube 2.

[0033] During use, according to the length of the centrifuge tube 3, adjust the distance between the support plate 205 and the tube 2, fix the support plate 205 through the locking bolt 203, insert the centrifuge tube 3 into the tube 2, and the centrifuge tube 3 is clamped and fixed under the action of the positioning block 4. Then hang the hanging basket on the rotor disc 1 so that the rotating shaft 202 is engaged with the hanging groove 102.
