door cover structure with hidden screws includes a glass panel, an inner door cover, a computer board and a sealing strip, an adhesive bracket is adhered to the back of the glass panel, the inner door cover is fixedly connected with the adhesive bracket through screws, and the computer board is arranged on the glass panel. In the cavity formed by the panel and the inner door cover, the inner door cover is provided with a sealing slot, the sealing strip is embedded in the sealing slot, and the bottom of the sealing slot is provided with a mounting hole for the screw to pass through, and the glue The bracket is provided with a fixing hole matched with a screw thread, and the screw passes through the installation hole of the inner door cover and is threadedly connected with the fixing hole of the adhesive bracket, so as to fixedly connect the inner door cover and the glass panel. The screw is hidden in the sealing groove of the door cover, and is sealed with water through the sealing strip. The appearance is beautiful, easy to disassemble and assemble, and it can effectively protect the screw from rust.
The traditional gasket is a single-piece gasket that works independently. This gasket mainly relies on friction to achieve the anti-loosening effect. The new washer is composed of two pieces. Its unique embedded structure changes the way that the traditional washer mainly achieves anti-loosening through friction. Instead, it adopts the most advanced anti-loosening technology in the world and uses the tension between the two gaskets to achieve. The dual effect of anti-loosening and tightening.
At present, in the era of industrialization, rivets used in specific occasions, automobiles, and aviation industries can only rely on professional tools and equipment to complete the riveting method.
The circlip is a common limiting element in the mechanical field, which is mainly used to limit the axial limit of mechanical parts. At present, the common circlips on the market are all circular rings with an opening. The circular ring has a certain elastic deformation capacity. When in use, the circlip can be detachably assembled to the mechanical on the part. However, the defect of the circlip adopting the one-piece ring is that the circlip is easily broken when frequently disassembled and used, and the service life is short.
