Description

Detachable joint structure

Technical field

The present invention relates to a connection structure, and particularly relates to a detachable joint structure.

Background technique

With the development of biomedical technology, biotechnology has been widely used in agriculture, food industry, medicine and other fields. Biotechnology includes genetic engineering, cell culture, and tissue culture technologies. Among them, cell culture is one of the basic implementation technologies in biomedical related research work. A common cell culture technique is to place cells in a multi-well microplate, and the porous microplate is covered with an outer cover, so that it can be cultured in a sterile environment without external interference (static). culture). After about a week, each cell will grow into a colony to achieve the purpose of reproduction.

However, since the most traditional joining method of the known porous microdisk and the outer cover is to directly use several screw fixing elements for screwing, and in the process of disassembly, the operator must use a tool to loosen the screwing element before it can be taken out. The cultivated samples have the problems of cumbersome, time-consuming, and difficult to disassemble, which is not an ideal design.

Summary of the invention

Therefore, the main purpose of the present invention is to provide a detachable joint structure, which can easily and quickly release the bonding state between the first and second bodies, so as to overcome the screw fixation between the known porous microdisk and the outer cover. The method has the problems of cumbersome, time-consuming and difficult to disassemble, which achieves the better benefit of disassembly.

The reason is that, in order to achieve the above-mentioned object, the detachable joint structure provided by the present invention includes: a first body having a first body, a first joint provided on the first body; and a The second body detachably connected with the first body has a second body part corresponding to the second joint part provided on the second body part corresponding to the position where the first joint part is located, and is used for connecting with The first joint part is combined to fix the first body and the second body to each other; wherein, when the first body and the second body are connected, the first body and the second body are There is a predetermined space between the facing end faces and communicates with the outside.

Wherein, the first joint portion has a recess that is concavely provided on the first body; the second joint portion has a protrusion that is protrudingly provided on the second body, and at least a part of the protrusion is combined with The concave surface of the concave, and the convex is embedded in the concave, and does not fill the concave, so that the space is located in the part of the concave not filled by the convex.

Wherein, the cross-sectional area of the protruding free end is smaller than the area of the concave concave surface.

In an embodiment of the present invention, it further includes a third body interposed between the first body and the second body, which has a flat structure.

Composed of the above-mentioned components, the space between the first body and the second body is used for the penetration of external tools for prying, so as to easily and quickly release the first body and the second body. The utility of the combined state between the second subject.

The beneficial effects of the present invention are:

The present invention provides a detachable joint structure, which can easily and quickly release the combined state between the first and second bodies, so as to overcome the cumbersome and time-consuming method of screw fixing between the known porous microdisk and the outer cover. The problem of not easy to disassemble, to achieve the better benefit of disassembly.

Detailed ways

First of all, please refer to Figures 1 to 4, the detachable joint structure provided in the first embodiment of the present invention mainly includes a first body 10 and a detachable joint structure with the first body 10 With the second body 20 connected in a manner, the first body 10 and the second body 20 are both approximately in the shape of a long sheet, and an accommodating space 30 is formed between the first body 10 and the second body 20. Wherein, the first body 10 and the second body 20 are made of hard plastic material, and are made by injection molding, and then further micro-engraving is used to cut the required line contour. Of course, it can also be used. Adopt precise one-piece molding without the need for secondary engraving processing.

The first body 10 has a first body 11 and a first joint 12 provided on the first body 11. Wherein, the first joining portion 12 has a recess 13 recessed on the first body 11, and the recess 13 is located on the peripheral side of the first body 11.

The second body 20 has a second body 21 corresponding to the second joint 22 provided on the second body 21 corresponding to the position where the first joint 12 is located, for connecting with the first joint 12 In combination, there is a predetermined space 40 between the facing end surfaces of the first body portion 11 and the second body portion 21 to communicate with the outside. Wherein, the second joint portion 22 has a protrusion 23 protruding on the second body 21. Since the cross-sectional area of the free end of the protrusion 23 is smaller than the area of the concave surface of the recess 13, the protrusion 23 It is embedded in the recess 13 without filling the recess 13 so that the space 40 is located at the portion of the recess 13 not filled by the protrusion 23. In the specific example of this case, the protrusion 23 and the recess 13 are connected by point-to-point ultrasonic welding, and at least a part of the protrusion 23 is combined with the concave surface of the recess 13, which means that the first The main body 10 and the second main body 20 are fixed to each other.

Through the composition of the above-mentioned components, the detachable joint structure can release the coupling state between the first body 10 and the second body 20, and use a tool (for example: tweezers) to extend into the first body 11 and the In the space 40 between the second body 21, the concave surface of the recess 13 is used as a fulcrum, and the end surface of the second body 21 is used as the focus point. With the welding relationship between the outlet 23 and the recess 13, the detachable joint structure can be easily pried open, achieving the effect of quick and easy disassembly.

Referring to FIGS. 5 to 8, in the second embodiment of the present invention, the main difference from the first embodiment is that a third body 50 is further provided between the first body 10 and the second body 20 , It is a flexible body made of silicone material.
