Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment provides an integrated slider dust cover, which comprises a metal scraper 1 and a plastic scraper 2, wherein mounting lips 3 with the same shape and size are arranged on the metal scraper 1 and the plastic scraper 2; the plastic wiper blade 2 is die-cast and adhered to one side of the metal wiper blade 1, so that the inner side surfaces of the two mounting lips 3 are positioned on the same plane. When processing, place the metal doctor-bar 1 that the punching process is good in the mould earlier for the installation lip 3 of metal doctor-bar 1 closely laminates the mould, then forms plastic doctor-bar 2 in metal doctor-bar 1 top die-casting shaping, because the limiting displacement of mould makes the installation lip 3 of plastic doctor-bar 2 also closely laminate the mould, thereby guarantees that two installation lips 3 are in the coplanar. Because the metal scraping blade 1 and the plastic scraping blade 2 are adhered together, only one part needs to be installed during installation, and the installation precision is easier to guarantee. The mounting lips 3 of the metal wiper blade 1 and the plastic wiper blade 2 do not need to be adjusted in position during locking, so that the mounting is more convenient.

In order to enable the metal scraping blade 1 and the plastic scraping blade 2 to be adhered more firmly after die casting, a concave part 12 is arranged on one side of the metal scraping blade 1, which is adhered to the plastic scraping blade 2, and a corresponding convex part 13 is formed on the other side of the metal scraping blade 1; one side of the plastic scraper 2 is provided with a reinforcing convex part 22 matched with the concave part 12, and the outer side wall of the reinforcing convex part 22 is tightly attached to the inner side wall of the concave part 12. The adhesive area between the metal scraping blade 1 and the plastic scraping blade 2 can be increased through the inner side wall of the concave part 12, and meanwhile, the stress direction is changed, so that the metal scraping blade 1 and the plastic scraping blade 2 are firmly connected.

Preferably, the inner side surface of the mounting lip 3 of the plastic wiper blade 2 is provided with a dustproof bulge 23, and the cross section of the dustproof bulge 23 is triangular. When the dustproof bulge part 23 is installed, the dustproof bulge part is in interference fit with the guide rail by 0.05mm-0.1 mm. A gap of 0.1mm-0.2mm is reserved between the inner side surface of the mounting lip 3 and the guide rail. Preferably, the distance between the highest point of the dustproof convex part 23 and the inner side surface of the installation lip 3 is 0.15mm-0.3 mm. Therefore, the metal scraper 1 can well remove large-particle impurities, and meanwhile, the guide rail cannot be damaged; meanwhile, the dustproof convex part 23 is in close contact with the guide rail, so that tiny impurities can be well removed.

Preferably, the other side of the plastic wiper blade 2 is provided with an installation chamfer 24, the installation chamfer 24 is located on one side of the dustproof protruding portion 23, and the inclined plane of the installation chamfer 24 coincides with one side of the dustproof protruding portion 23. Can make the slider easy to assemble on the guide rail, make simultaneously the resistance between dustproof bellying 23 and the guide rail reduce, can buckle towards dustproof bellying 23 both sides when the resistance is great to avoid the card dead.

Preferably, three sides of the metal scraper 1 are provided with positioning and mounting holes 11, the plastic scraper 2 is provided with U-shaped openings 21 at the positions of the positioning and mounting holes 11, and the positioning and mounting holes 11 are located in the U-shaped openings 21. When die casting is performed by using a die, the positioning mounting hole 11 and the U-shaped opening 21 can play a good positioning role, so that the die casting precision is ensured, and the mounting lip 3 precision is ensured.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
