Description

Technical Field

[0001] This utility model relates to the field of bolt cover plate technology, and more specifically to a movable snap-on bolt cover plate. Background Technology

[0002] Screws are very common connecting components, widely used in the assembly of various mechanical structures. After screws are tightened, screw covers are used to enclose them, serving both an aesthetic purpose and a protective function, preventing them from being exposed and susceptible to rust or impact damage. Existing screw covers typically involve directly slipping the cover onto the screw base, a simple and quick installation method. However, this method also has drawbacks: the screw cover can easily detach from the base, exposing the screw and making it prone to rust, affecting its lifespan and even disrupting the normal operation of the equipment. Therefore, a screw cover that can securely hold the base in place is needed to cover the screw and prevent it from being exposed. To address this, the inventor proposes a movable snap-on screw cover. A movable snap-on device is used between the screw cover and the base, allowing the screw cover to be securely fastened to the base. When disassembly is needed, the snap can be easily released to remove the screw cover, preventing it from detaching during use and facilitating disassembly and maintenance.

[0003] To ensure precise and secure installation of screw base plates and screw covers, preventing them from easily falling off, Chinese Patent (Authorization Announcement No.: CN208364582U) discloses an aluminum screw cover. This utility model includes a base post with a first circular hole on its upper surface. A threaded post is threaded into the inner wall of the first circular hole, and a top cover is fixedly installed on the top of the threaded post. A plate is movably installed above the base post. Placement grooves are formed at both ends of the upper surface of the base post. A first spring is fixedly installed on the bottom wall of the placement groove. A movable rod connected to the plate is movably installed at the end of the first spring away from the bottom wall of the placement groove. A second circular hole connected to the threaded post is formed in the middle section of the upper surface of the plate. This utility model, through the placement grooves on the upper surface of the base post, the installed first spring, and the installed movable rod, prevents the plate from moving during installation, making it very convenient to use. The soft pad further enhances the secure connection of the screw.

[0004] The solution still has some shortcomings in application. In some scenarios, the screw cover plate needs to be disassembled periodically after installation to unscrew the screws for equipment maintenance. If it is a fixed structure with snap-fit, it is inconvenient to disassemble, which is troublesome and cannot be reused, resulting in wear and tear on the screw cover plate. Therefore, the structure of the screw cover plate needs to be improved to overcome the above-mentioned limitations, make it more in line with the needs, enable quick installation and removal, extend its service life, and effectively improve its practical performance.
