FIG. 2 is an enlarged view of a portion of FIG. 1;

fig. 3 is a partially enlarged view of another embodiment.

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.

Example 1:

please refer to fig. 1 and fig. 2, which are a perspective view and a partial enlarged view of the anti-contamination device 1 for PCR reaction samples according to the present invention.

The PCR reaction sample anti-pollution device 1 comprises a box body 11, a cross beam 12, a top door 2 and a side door 3. The box body is a flat square box with 11 positions, and the top surface and one side surface of the box body are provided with openings. The top surface opening is provided with 11 beams 12 at equal intervals and at an angle parallel to the wide side of the top surface opening, so that 12 through grooves are formed, and the through grooves just correspond to 12 columns of a common sample plate (a 96-hole plate). The space inside the box body 11 also corresponds to the space, so that the sample plate can be smoothly placed, a larger gap can not be generated, and the situation that the sample plate is greatly shaken during moving is avoided.

Each the inboard that leads to the groove, be on a parallel with the angle of the broadside of box body 11, the symmetry is equipped with two sand grips 21, the both sides of overhead door 2 are equipped with the recess 22 that corresponds with it, utilize the linking of the two, will 12 overhead door 2 one-to-one inserts each it leads to the inslot (for the convenience of show, only set up half in the drawing overhead door 2). Handles 4 are respectively arranged at two ends of the top surface of the top door 2 to assist in pushing and pulling. The bottom surface of the top door 2 is also provided with a limiting head 23, so that the top door 2 is prevented from being completely drawn out, and the use is prevented from being influenced.

Two hinges 31 are provided on the bottom surface of the box body 11 near the edge of the side opening. Hinge 31 one side is fixed in the bottom surface of box body 11, the opposite side is fixed in the bottom of side door 3. A small section of the shaft of the hinge 31 is further extended and sleeved with a torsion spring 32. The same two sides of the torsion spring 32 are respectively abutted against the bottom surface of the box body 11 and the bottom end of the side door 3. The side door 3 is normally closed. Two handles 4 are also arranged at the positions, close to the top, of the outer sides of the side doors 3 to assist opening and closing.

In specific implementation, after the side door 3 is broken, the sample plate is inserted into the opening on the right side, and the side surface 3 is loosened to seal the box body 11. When the sample is needed to be added, the top door 2 at the corresponding position is pulled open, and the top door is closed after the sample addition is finished. Furthermore, can also mark the serial number on the top door 2, produce when avoiding the application of sample and obscure.

Example 2:

referring to FIG. 3, a partial enlarged view of the PCR reaction sample contamination prevention device 1 according to the present invention is shown in the present embodiment, and the enlarged position is the same as that shown in FIG. 2.

Compared with the embodiment 1, the side door 3 is connected with the box body 11 by adopting a plug-type structure. The side door 3 is close to one side of the box body 11, a circle of bulges in transition fit with the side openings are arranged, and the side door 3 is fixed through friction after being plugged in.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
