Four through-holes four of arrangement.
The U-shaped rubber weather strip includes U-shaped rubber matrix and metal clips, and U-shaped rubber matrix wraps up metal clips；
Each through-hole two runs through U-shaped rubber matrix and metal clips；The global shape of U-shaped rubber matrix and metal clips is and center
The shape in hole one is consistent.The both ends in U-shaped rubber matrix section are U-shaped.The both ends in metal clips section are also U-shaped.
The utility model has the advantages that
1, due to there is the U-shaped structure of U-shaped rubber weather strip, Double-protection is played, and it is close by compressing member to compress U-shaped rubber
Strip of paper used for sealing, sealing effect greatly promote.
2, due to there is the use of compressing member, screw during the fastening process, can be to avoid existing cabinet due to welding bring
Deformation influences, to promote cabinet sealing performance, efficiently solves the substances such as water or dust as screw thread gap enters
The problem of cabinet.
3, due to the Double-protection of U-shaped rubber weather strip U-shaped structure, and U-shaped rubber weather strip can be with elastic component
Buffer function is played to a certain extent, is suitable under vibration environment, and panel and cabinet or cabinet and briquetting are this when avoiding vibrating
Collision between rigid member influences product structure.
4, since the U-shaped structure of U-shaped rubber weather strip can wrap up the frame that cabinet needs to seal, so that reducing cabinet needs
The hidden danger such as body incised wound or material incised wound in the brought operating process of the defects of wanting the burr on sealed frame.
