Description

Technical Field

[0001] The utility model relates to the technical field of test tube racks, in particular to a test tube rack for food testing. Background Art

[0002] A test tube rack is the most basic experimental instrument in a chemical laboratory for placing and drying test tubes. Test tubes are often used in the field of food testing, and the test tube rack supports the test tubes. The existing test tube rack includes a support frame, on which a socket is provided. When placing the test tube, the test tube can be supported by passing the test tube through the socket.

[0003] In the field of food testing, test tubes of different diameters are used, so the existing test tube rack will set a limiting structure in the socket to clamp and limit the test tube. The limiting structure of the existing test tube rack includes two clamping members with relative linear displacement, but the displacement direction of the clamping member is perpendicular to the displacement direction of the test tube entering the socket, resulting in greater obstruction when the test tube is directly inserted into the socket and passes between the two clamping members, making direct insertion difficult and requiring manual opening of the two clamping members, which brings trouble to food testing operations. Utility Model Content

[0004] The utility model provides a test tube rack for food testing, which can overcome the defect of the prior art that it is inconvenient to directly insert a test tube.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0008] Through the clamping assembly of the utility model, the test tube passing through the socket can be clamped and limited, and test tubes with different diameters can be limited. At the same time, through two tiltable and rotatable flaps and a clamping block rotatably connected to the flaps, the two flaps can be spread apart when the test tube is directly inserted, and the rotatable clamping block can make the direct insertion of the test tube easier.

[0009] Among them, the setting of the rotating connection of the clamp block makes it easier for the two flaps and the clamp block to open when the test tube is inserted between the two clamp blocks, and the two clamp blocks can automatically flip the angle to fit the wall of the test tube, making it easier to insert the test tube directly.

[0010] The setting of the tension spring makes the two clamping blocks always tend to be in contact, so that when clamping the test tube, there is a certain clamping force to stabilize the test tube.

[0015] Preferably, a slot is provided on one side of the flap away from the rotating rod, a rotating shaft is rotatably connected in the slot, the clamping block is connected to the circumference of the rotating shaft, and the torsion spring is sleeved on the outside of the rotating shaft, with its two ends respectively connected to the flap and the clamping block.

[0016] In the utility model, by setting the torsion spring, when the two flaps are in relative inclination, the two clamping blocks can also maintain relative inclination, so that the opening between the two clamping blocks is larger at the top and smaller at the bottom, making it easier to insert the test tube between the two clamping blocks.

[0017] Preferably, an arc-shaped clamping portion is provided on one side of the clamping block away from the rotating shaft, the curvature of the clamping portion matches the curvature of the socket, and a sponge pad is fitted and connected to the arc surface of the clamping portion.
