CN-224227270-U - Anti-deformation structure for shielding chromium plating product

Abstract

The utility model relates to the technical field of shielding chromeplated products and discloses an anti-deformation structure for shielding chromeplated products, which comprises a base and an opening strip, wherein the base and the opening strip are integrally formed, a connecting block is fixedly arranged at one end of the opening strip far away from the base, a rib is fixedly arranged at the inner edge of the connecting block, both ends of the rib are connected with the connecting block, a groove I is formed at one end of the opening strip far away from the base, a clamping frame is arranged at one end of the opening strip close to the groove I, and a limiting frame is fixedly arranged at both ends of the clamping frame far away from a central line. This shelter from deformation structure of chromeplate product, rib regard as interim support at chromeplate in-process, can effectively offset the deformation force that the opening contracts, because the rib both ends are all connected with the connecting block, when the injection molding opening received inwards extrusion force, the rib can be with stress dispersion to connecting block and opening strip, wait to electroplate the back, can follow the junction shearing of rib and connecting block, get rid of interim bearing structure, does not remain unnecessary material.

Description

Anti-deformation structure for shielding chromium plating product Technical Field The utility model relates to the technical field of shielding chromium plating products, in particular to an anti-deformation structure for shielding chromium plating products. Background When shielding chromium plating production, when needing to carry out local chromium plating to shielding piece, because of shielding piece is heated inhomogeneous because of the heat conduction difference with chromium plating region, the material molecular chain in opening position produces the shrink because of thermal stress effect, leads to the opening position to produce the shrink deformation, influences product precision and function to often use the shape structure of preapring for an unfavorable turn of events, thereby avoid its opening position to produce the shrink deformation. In the prior art, the shielding piece is often not provided with a deformation prevention structure, so that the material of the injection molding piece is heated unevenly easily, the opening of the shielding piece is deformed, or the shielding piece is prevented from being deformed by adopting simple means such as adhesive tapes, clamps and the like, the production cost is high, and the shielding piece is easy to damage a product, so that the follow-up normal use is influenced. Disclosure of Invention The utility model aims to solve the technical problem of providing the deformation preventing structure for shielding the chromeplated product, which can effectively solve the problems that in the prior art, the deformation preventing structure is not designed frequently, and the material of an injection molding part is heated unevenly easily, so that the opening of the injection molding part is deformed, or the deformation of the injection molding part is prevented by adopting simple means such as adhesive tapes, clamps and the like, so that the production cost is high, the product is damaged easily, and the subsequent normal use is influenced. The technical scheme includes that the deformation-preventing structure for shielding a chromed product comprises a base and an opening strip, wherein the base and the opening strip are integrally formed, a connecting block is fixedly arranged at one end, far away from the base, of the opening strip, ribs are fixedly arranged at the inner edge of the connecting block, two ends of the ribs are connected with the connecting block, a groove I is formed at one end, far away from the base, of the opening strip, a clamping frame is arranged at one end, close to the groove I, of the opening strip, two ends, far away from a central line, of the clamping frame are fixedly provided with limiting frames, and the diameter of each limiting frame is larger than that of each clamping frame. Preferably, the first buckle and the second buckle are fixedly arranged on the extending part of the base, which is close to the opening strip, and the first buckle and the second buckle are provided with the same plurality of buckles and are annularly distributed relative to the base.
