Detailed Description

The following detailed description of the present application is given for the purpose of enabling those skilled in the art to better understand the technical solutions of the present application, and the description in this section is only exemplary and explanatory, and should not be taken as limiting the scope of the present application in any way.

Example 1:

referring to fig. 1 to 3, the embodiment provides a foaming structure of a bracket, including a bracket and a foaming layer 2 injection-molded on the bracket, where the foaming layer 2 is made of EVA (ethylene vinyl acetate), the bracket is made of PA66 (polyhexamethylene adipamide, commonly called nylon-66), the bracket includes a bracket main body 1 and an outer edge 3 disposed around the bracket main body 1, a connection portion 4 is vertically disposed on the outer edge 3, the connection portion 4 includes a first protrusion 5 and a second protrusion 6 disposed at a free end of the first protrusion 5, the first protrusion 5 is a columnar protrusion, the second protrusion 6 is disposed at one side of the first protrusion 5 and perpendicular to the first protrusion 5, and a first through hole 7 for embedding the foaming layer 2 is disposed at a position on the outer edge 3 corresponding to the second protrusion 6. The bracket and the foaming layer 2 are mutually hooked through the second bulge 6 and are not easy to fall off; through setting up first through-hole 7, make foaming layer 2 pass through first through-hole 7, further block foaming layer 2 and break away from the support.

Preferably, the support main body 1 is provided with liquid passing holes 8 for allowing electrophoresis liquid to flow through, in this embodiment, two liquid passing holes 8 are provided, in other embodiments of the present application, other numbers of liquid passing holes 8 can be further provided according to actual requirements, each liquid passing hole 8 is provided with a circle of inner edge 9, the inner edge 9 is provided with a connecting portion 4 which is consistent with the structure of the outer edge 3, the inner edge 9 is provided with a second through hole 10 corresponding to the second protrusion 6 for embedding the foaming layer 2, and the support main body 1 is provided with a connecting groove 11 for communicating the outer edge 3 with the inner edge 9. By providing the connection portion 4 and the second through hole 10 around the liquid passing hole 8, the bracket can be better attached to the foaming layer 2, and the foaming layer 2 can be effectively prevented from being detached from the bracket.
