Example 1:

referring to FIG. 1, an embodiment of the present utility model provides an anti-volatilization integrated test tube plug, comprising

The elastic soft board 1 is generally made of plastic materials, such as TPE and soft PVC; since a plurality of test tubes for textile detection are generally arranged in an array, the elastic flexible plate 1 is generally rectangular and covers just above the test tube array;

the plurality of test tube plugs 2 are uniformly distributed on one side surface of the elastic flexible plate 1, and the arrangement rules of the plurality of test tube plugs 2 are consistent with the arrangement rules of the plurality of test tubes on the test tube rack, so that when the elastic flexible plate 1 is parallel to the test tube arrangement plane, the lower ends of the test tube plugs 2 are aligned with the test tubes one by one; and a detachable connecting piece is connected with the upper ends of the elastic flexible plate 1 and the test tube plug 2.

The elastic flexible plate 1 needs to have flexibility and elasticity at the same time, so that the test tube plugs 2 need to be inserted into the test tubes one by one; the test tube plugs 2 are aligned with the test tube array, and after the test tube plugs 2 on one side are inserted, the test tubes which are not inserted on the other side are different from the inserted test tube plugs 2 in height, so that the test tube plugs 2 are inclined in position.

The flexibility and elasticity of the flexible plate 1 is required to adjust the position of the test tube stopper 2 which has not been inserted yet, and the offset between the test tube stoppers 2 after insertion is not large.

The flexible plate 1 is a flexible plate-shaped structure (TPU only) made of transparent plastic materials, so that an operator can observe the test tube plug 2 below the flexible plate 1 through the flexible plate 1, and the usability of the device is improved.

In this embodiment, the detachable connection member is a screw 3, which has low cost and is easy to obtain materials, and is practical.

Since the test tube stopper 2 is also made of a soft elastic material to seal the test tube by self deformation, and the screw 3 is fixed to the test tube stopper 2 by the engagement of the screw thread a, the self deformation capability of the test tube stopper 2 easily causes the test tube stopper 2 to be pulled out from the engagement of the screw thread a, so that this embodiment provides another embodiment of the detachable connection member.

Example 2:

referring to fig. 2, this embodiment is different from embodiment 1 in that:

the screw 3 is replaced with a snap-in structure.

The fastening structure comprises a groove 41 arranged at the upper end of the test tube plug 2 and a pipe fitting 42 which is arranged on the elastic flexible plate 1 and used for extending into the groove 41; the movable part 43 and the piston 44 which are connected with each other are movably arranged in the pipe fitting 42, the piston 44 is abutted against the inner wall of the pipe fitting 42, and the movable part 43 axially moves by driving the piston 44 so as to form negative pressure or normal pressure between the inner cavity of the pipe fitting 42 and the groove 41, and the negative pressure or normal pressure is respectively used for adsorbing the test tube plug 2 or removing the adsorption of the test tube plug 2. The upper end of the pipe fitting 42 is provided with an upper clip 45 for clipping the elastic compliance plate 1. The lower end of the tube member 42 is provided with a lower clip 46 for forming a concave-convex surface fit with the groove 41 of the test tube stopper 2. When a negative pressure is formed between the inner cavity of the tube member 42 and the groove 41, the inner wall of the tube member 42 is connected to the movable member 43 by the screw thread 47.

Working principle: firstly, an upper clamp 45 above a pipe fitting 42 is inserted into a preset hole of an elastic flexible plate 1, the upper clamp 45 is connected with the elastic flexible plate 1 in a blocking way through the elasticity of the elastic flexible plate, then the lower end of the pipe fitting 42 is inserted into a groove 41 at the upper end of a test tube plug 2 (through manual fixing of the position of the test tube plug 2), at the moment, a movable part 43 in the pipe fitting 42 is pulled upwards until a thread 47 of the movable part 43 is contacted with the inner wall of the pipe fitting 42, then the movable part 43 is rotated to clamp the thread 47, so that the movable part 43 is fixed at the thread 47, in the process, the volume of a sealing space formed by a piston 44 and the lower end of the groove 41 is enlarged, and then the test tube plug 2 is tightly adsorbed on the pipe fitting 42 by negative pressure, and the test tube plug 2 is locked through the vacuum adsorption mode.
