Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a liquid rack for chemistry experiments, from the top includes base 1, roof 2, support column 4 and test tube body 6 in proper order, and screw and base 1 fixed connection are passed through to the one end of support column 4, and screw and 2 fixed connection of roof are passed through to the other end of support column 4, and support column 4 is provided with two altogether and fixes the both sides at base 1 respectively. A plurality of through holes 21 are formed in the top plate 2 in a penetrating manner, and a clamping device 3 is mounted in each through hole 21. Through installation clamping device 3, can carry out the centre gripping to test tube body 6 to let better the fixing on roof 2 of test tube body 6. The test tube body 6 passes through the through hole 21 to contact with the base 1 and is fixed on the top plate 2 by the clamping device 3.
As shown in fig. 1, 2 and 3, the clamping device 3 includes a clamping block 31, a push rod 32, a spring 33 and a pushing block 34, a movable cavity 22 is provided in the top plate 2 corresponding to each through hole 21, the movable cavity 22 is communicated with the through holes 21, the clamping block 31, the spring 33 and the push rod 32 are sequentially placed in the movable cavity 22 from inside to outside, one end of the push rod 32 is fixedly connected with the clamping block 31 through a screw, and the other end of the push rod 32 penetrates through the movable cavity 22 of the spring 33 and the top plate 2 respectively and is welded and fixed with the pushing block 34. The length of the push rod 32 should be smaller than the length of the movable cavity 22 so as to ensure that the clamping block 31 does not completely separate from the movable cavity 22.
As shown in fig. 1 and 4, the base 1 is provided with a plurality of placement grooves 11, the placement grooves 11 are matched with the through holes 21, and rubber pads are bonded inside the placement grooves 11. Come bearing test tube body 6 through setting up the standing groove, not only can play certain limiting displacement to test tube body 6, can also make test tube body 6 place more stably at base 1. The lower end of the base 1 is provided with a plurality of suckers. The test tube rack can be placed on the experiment table more stably through the installation of the sucker, and the test tube rack cannot be turned over easily.
As shown in fig. 1 and 4, a plurality of airing rods 5 are welded at the opposite positions of a base 1 and a placing groove 11, the airing rods can be used for fixing and cleaning test tubes, a plurality of annular grooves 12 are uniformly formed around the airing rods 5 on the base 1, each annular groove 12 is communicated with each other through a drainage groove 13, the drainage grooves 13 are linearly distributed on the base 1 and are obliquely arranged, and the drainage grooves and the horizontal plane form an included angle of 15 degrees, so that the water dripping in the test tubes can be better discharged.
As shown in fig. 1 and 3, the end of the clamping block 31 contacting the test tube body 6 is a cambered structure, and a rubber layer is adhered to the outer side wall of the end of the clamping block 31 having the cambered structure. Through setting up clamp splice 31 to cambered surface structure, it is fixed with its centre gripping to agree with test tube body 6 that can be better, through setting up the rubber layer, can avoid clamp splice 31 and the direct rigid contact of test tube body 6 to protect test tube body 6, reduced the probability of damage.
As shown in fig. 1 and 3, the push block 34 is curved, the curve is easy to hold, the outer side wall of the push block 34 is provided with anti-slip threads, a rubber buffer ring is arranged at the contact position of the push block 34 and the top plate 2, and the rubber buffer ring is sleeved outside the rubber buffer ring. By installing the rubber buffer ring, the push block 34 can be prevented from directly contacting the top plate 2 and a certain buffer effect can be achieved.
The working principle is as follows: when carrying out the chemical experiment, at first place the test-tube rack on the test bench, under the effect of sucking disc, make test tube rack fix on the test bench. Then the test tube with liquid is passed through the through hole 21 and inserted in the placing groove 11, in this process, before the test tube is passed through the through hole 21, the user needs to hold the push block 34 to pull the whole holding device 3 outwards until the clamp block 31 disappears completely in the through hole 21, then put the test tube into the through hole, and then slowly release the push block 34, because the spring 33 is deformed under the action of the pressure between the clamp block 31 and the push block 34, the connecting rod 14 moves backwards, so that the test tube is fixed on the top plate 2, and the test tube is buckled, for the cleaned test tube, the test tube is reversely buckled on the airing rod 5, at this time, the residual water drops in the test tube flow into the annular groove 12 along the side wall of the test tube, and because the drainage groove 13 is arranged in an inclined plane form, the water drops in the annular groove 12 can be easily drained into the drainage groove 13 and discharged.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
