Description

[0001] The utility model relates to the technical field of laboratory equipment, in particular to a test tube placing device for a laboratory. Background Art

[0002] Laboratory equipment is a general term for various instruments, devices and equipment necessary for scientific research and experimental activities. When conducting experiments in the laboratory, test tubes are needed to react to small amounts of reagents. After use, the test tubes need to be placed, so test tube placement equipment is needed.

[0003] According to Chinese patent publication number CN219334300U, a test tube rack for a laboratory comprises a test tube rack body, the test tube rack body comprises a fixing part and two relatively arranged telescopic parts, the two telescopic parts are relatively arranged up and down, and both ends of the two telescopic parts are fixed on both sides of the inner wall of the fixing part, the limiting column is pulled to disengage the limiting groove and the sliding plate, and the second fixing plate is moved to make the sliding rod and the fixing block move inside the slide rail, and when the fixing block moves to one side of the limiting block, the limiting block blocks the fixing block so that the sliding plate does not move out of the supporting plate, and when the sliding plate is adjusted, the limiting column is inserted into the limiting groove so that the limiting column passes through the limiting groove and both sides of the sliding plate so that the sliding plate does not move left and right due to shaking. Through the above structure, the operator does not need to prepare multiple test tube racks when doing experiments, which reduces the labor intensity of the operator during the experiment to a certain extent and saves the operator's preparation work before the experiment.

[0004] However, when the operator of the above device places the test tube in the test tube rack, he only places the test tube in the test tube rack, which causes the test tube to tilt along with the test tube rack when encountering a collision, causing the objects in the test tube to spill out, affecting the progress of the experiment. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a laboratory test tube placement device, including a bracket, a buffer pad is fixedly connected to the inner bottom wall of the bracket, a flap is rotatably connected to the outer wall of the bracket, a fixing bolt is threadedly connected to one side of the flap, a fixing mechanism is slidably connected to the inner wall of the flap, one end of the fixing mechanism slides and engages with one end of the fixing bolt, a placement rack is fixedly connected to the inner wall of the bracket, a clamping mechanism is fixedly connected to the inner wall of the placement rack, the clamping mechanism and the fixing mechanism correspond to each other, a placement plate is fixedly connected below the bracket, and a suction cup is fixedly connected below the placement plate.

[0007] Preferably, the fixing mechanism includes sliding rods which are all slidably connected to the inner wall of the flap. One end of each sliding rod is fixedly connected with a limiting plate, and the other end of each sliding rod is fixedly connected with a pressing plate. One end of each limiting plate is fixedly connected with a first spring.

[0008] Preferably, the surfaces of the first springs are all slidably sleeved on the surfaces of the limiting plates, and one end of each first spring is fixedly connected to the surface of the flap.

[0011] Preferably, sliding grooves are formed on the inner walls of the placement racks, and the clamping plates are all slidably connected in the sliding grooves.

[0012] Preferably, arc grooves for clamping test tubes are formed on the surfaces of the clamping plates.

[0013] The working principle and usage principle of the present utility model are as follows: Place the placement plate on the surface of the experimental table, so that the suction cups adsorb on the surface of the experimental table to stabilize the bracket. Place the test tube in the arc groove on the inner wall of the clamping plate. The arc groove facilitates clamping the test tube. Drive the clamping plate to slide in the inner wall of the placement rack through the second spring to fix the test tube. At the same time, the second spring can facilitate the clamping plate to fix test tubes of different specifications. Flip the flap so that the flap reaches above the test tube. Loosen the fixing bolt so that one end of the fixing bolt disengages from the fixing groove. Press the limiting plate so that the limiting plate drives the sliding rod to move downward. At the same time, the sliding rod drives the pressing plate to contact the upper part of the test tube, and at the same time compress the first spring. Then rotate the fixing bolt so that one end of the fixing bolt is clamped in the fixing groove to fix the sliding rod, so that the lower part of the test tube contacts the buffer pad to buffer the lower part of the test tube and stabilize the test tube, which is convenient for stabilizing the test tube and preventing the test tube from tilting when encountering collisions to protect the objects in the test tube.

[0014] The beneficial technical effects of the present utility model are: Place the placement plate on the surface of the experimental table, so that the suction cups adsorb on the surface of the experimental table to stabilize the bracket. Place the test tube inside the clamping mechanism so that the clamping mechanism clamps and fixes the test tube. Flip the flap so that the flap reaches above the test tube. Loosen the fixing bolt and slide the fixing mechanism so that the lower part of the fixing mechanism contacts the upper surface of the test tube, and the lower part of the test tube contacts the buffer pad to buffer the lower part of the test tube. Then fix the fixing bolt so that one end of the fixing bolt is clamped in the fixing mechanism to fix the fixing mechanism and stabilize the test tube, which is convenient for stabilizing the test tube and preventing the test tube from tilting when encountering collisions to protect the objects in the test tube.
