Description

Sliding locking device

Technical Field

The invention belongs to the technical field of locking mechanisms, and particularly relates to a sliding locking device.

Background

Along with the continuous improvement of living standard and technology level in recent years, the demand and dependence of people on electronic products are increased; for electronic products, on the premise of meeting the use performance of the electronic products, higher requirements are provided for the appearance, the portability and the disassembly convenience of the electronic products; in particular, the connection mode of the components in the digital product is particularly concerned by the developers of the product.

Currently, detachable connection means of digital product housings include bolted connections and snap connections. For example: the patent document with the application number of 201210113721.4 discloses an outer shell of an electronic product, which comprises a main shell, wherein an opening is formed in the main shell, a cover plate is arranged outside the opening of the main shell, a bolt is arranged between the cover plate and the main shell, an annular sealing ring installation groove surrounding the opening in the main shell is formed in the main shell, an annular elastic sealing ring is arranged in the sealing ring installation groove, an annular sealing ring pressing bulge is arranged on the cover plate, the cross section of the sealing ring pressing bulge is a wedge-shaped surface, and the inclined side surface of the sealing ring pressing bulge is pressed on the sealing ring; wherein, the bolt connection structure is firm, but the installation takes time and the disassembly is inconvenient; therefore, it is often used with or directly with a snap connection to reduce the amount of bolt connections used.

The buckle provides a convenient, fast, economical and practical product assembling method, and is mainly characterized in that the buckle is directly formed with a finished product in the product manufacturing process, independent locking accessories such as screws, mesons and the like do not need to be matched during assembling, and only a pair of male and female buckles to be combined need to be matched and buckled with each other during assembling. For example, patent document No. 201410493902.3 discloses a liquid crystal television, which includes a front casing, a rear casing, and a liquid crystal display module disposed between the front casing and the rear casing; the front shell comprises a front shell side wall, a first buckling part and a first convex part, and the first buckling part and the first convex part are arranged on the end face of the front shell side wall; the rear shell comprises a rear shell side wall and a second buckling part arranged on the inner wall surface of the rear shell side wall; the first buckling part is in buckling fit with the second buckling part, the first convex part is in interference fit with the inner wall surface of the side wall of the rear shell, the end surface of the side wall of the front shell is in interference fit with the end surface of the side wall of the rear shell, and the outer wall surface of the side wall of the front shell is aligned and spliced with the outer wall surface of the side wall of the rear shell. Although the design of the buckle has various geometric shapes, the operation principle is the same, namely when two parts are buckled, the hook-shaped extension part of one part is pushed away by the flange part of the connected part until the flange part is finished; then, by virtue of the elasticity of the plastic, the hook-shaped extending part is reset in real time, the groove behind the hook-shaped extending part is embedded by the flange part of the connected part in real time, and the inverted buckle forms a mutually buckled state when being placed. However, the design of the locking slot and the hook is usually easy to install but difficult to disassemble; even if the buckle is detached, the buckle is also easy to be damaged, so that the inconvenience of installation, detachment and use is further caused, and the cyclic use is not facilitated.

Therefore, how to develop a locking device which is convenient to disassemble becomes a research hotspot.
