Description

Hand-detachable case structure

technical field

The utility model relates to a hand-detachable case structure, in particular to a hand-detachable case structure suitable for desktop computers.

Background technique

The function of the computer case is to protect the precise electronic components inside the computer, to isolate the interference from the external environment, and to avoid damage to the electronic components due to improper external forces.

With the increase of computer popularization rate and the orientation of user segmentation, the electronic components inside the computer can be replaced or adjusted according to the needs of users; therefore, the computer case needs to be opened frequently, and the number of disassembly is very frequent.

However, looking at the known computer casings, it is not a split structure, that is, a door-shaped structure. These structures are embedded in the frame of the computer body in one direction with the snap-fitting piece inside, and the rear end is locked on the frame of the computer body with screws. If the computer case is to be disassembled, the locking screw at the rear end of the computer case must be removed with a tool, and then the computer case is separated from the computer body frame in a sliding manner.

These known computer casing structures, whether it is a split-type computer casing structure or a door-shaped computer casing structure, are not only difficult to disassemble, but also except that the rear end is locked by screws, the rest of the computer casing Only the one-way locking piece is used to fit the computer body frame. The overall structure of the computer case is not strong enough, and the structural appearance is even more uninspiring. In addition, before the system is assembled and leaves the factory, the assemblers need to spend a lot of time installing the computer case. Looking at the above, it is not very ideal.

Utility model content

The purpose of the utility model is to provide a hand-detachable case structure, the user can easily open the computer case without additional tools, and replace or adjust the internal electronic components. In addition, the computer casing is an integral one-piece top cover, and the top cover and the machine base can be opened without being completely separated, which improves the strength and stability of the casing structure. Furthermore, before the system is assembled and leaves the factory, the assembler does not need to spend a lot of time installing the computer case, and can just close the top cover to complete the case assembly, greatly improving work efficiency.

The utility model relates to a hand-detachable computer casing structure, which includes a base and an upper cover. The base has two side walls, two sets of engaging parts, and two lugs. At appropriate positions on both sides of the two side walls, engaging parts are assembled respectively. On both sides of the rear ends of the two side walls, upwardly protruding lugs are respectively fixed. Each lug has a longitudinal slot and a guide slot. The guide groove then has a straight section parallel to the longitudinal slot. The upper cover has two side plates, and the inner sides of the two side plates respectively have a hand-operated engaging element, a rotating shaft, and a guide pin.
