Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1-6, a test tube fixing device, including base 1, backup pad 2, support column 3, grip block 4 and grip block 5, install on base 1 support column 3 lower extreme, the upper end suit is in grip block 4, and backup pad 2 is fixed on support column 3 to be located base 1 top, a plurality of first centre gripping recesses 41 have evenly been arranged along the circumferencial direction in grip block 4 outside, have centre gripping guide bar 42 at first centre gripping recess 41 bilateral symmetry arrangement, the 5 suits of grip block are at centre gripping guide bar 42, grip block 5 is provided with the second centre gripping recess 51 symmetrical with first centre gripping recess 41, it is equipped with spring 6 to lie in 5 rear cover of grip block on the centre gripping guide bar 42, passes through lock nut 7 behind spring 6 and fixes on centre gripping guide bar 42. The clamping guide rod 42 is in threaded connection with the locking nut 7, and is convenient to mount and dismount. Adopt this technical scheme, when using, directly manual remove grip block 5 (remove grip block 5 as shown in fig. 5) along centre gripping guide bar 42 to the grip block 4 outside, put into test tube 10 between first centre gripping recess 41 and the second centre gripping recess 51, then loosen the hand, make grip block 5 draw close to first centre gripping recess 41 under the effect of spring 6, make first centre gripping recess 41 and second centre gripping recess 51 realize jointly that the centre gripping to test tube 10 is fixed, and convenient for operation, and make grip block 5 be difficult for becoming flexible under the effect of the elasticity of spring 6, ensure the centre gripping stability.

The supporting plate 2 is correspondingly provided with a supporting groove 21 below the first clamping groove 41, and the center of the supporting groove 21 and the center of the cylinder combined by the first clamping groove 41 and the second clamping groove 51 are on the same vertical line. This ensures that the test tube 10 passes between the first holding recess 41 and the second holding recess 51 and then is positioned right opposite to the inside of the holding recess 21, ensuring that the test tube 10 is not tilted. Support recess 21 and set up to hemisphere groove structure, be convenient for and test tube bottom cooperation.

The outer side wall of the clamping plate 4 is at least provided with two locking bolts 11, and the two locking bolts 11 are symmetrically arranged. The clamping plate 4 is locked on the supporting column 3 after the height position of the clamping plate 4 on the supporting column 3 is adjusted.

For the center of ensureing that support recess 21 and first centre gripping recess 41 and second centre gripping recess 51 on the backup pad 2 make up into the cylinder all the time on same vertical line, the utility model discloses it is provided with reference column 22 to be located 3 bilateral symmetry of support column at backup pad 2, and reference column 22 passes grip block 4, ensures that grip block 4 can only reciprocate along support column 3, and can not produce the rotation, and then avoids support recess 21 to produce the dislocation.

The lower end of the support column 3 is positioned below the support plate 2 and is provided with an installation section 23, and the installation section 23 is installed in the base 1 through a bearing 9. In this way, the lower end of the support column 3 is rotatably mounted on the base 1, so that the holding plate 4 can be selected to facilitate the insertion or removal of the test tube 10 in the same position.

As shown in fig. 6, the buffer layer 8 is disposed on the inner wall of each of the first and

second clamping grooves

41 and 51. Buffer layer 8 can play the cushioning effect, prevents that test tube 10 from being hindered by the clamp, can make the inner chamber of centre gripping test tube 10 slightly be less than the cylinder inner chamber that first centre gripping recess 41 and second centre gripping recess 51 are constituteed after increasing buffer layer 8 simultaneously, further increases the stability of centre gripping test tube. The buffer layer 8 can be made of sponge, cloth strip or rubber.
