Description

Technical Field

[0001] The utility model relates to a controller shell structure, in particular to a hanging type controller protection shell. Background Art

[0002] In order to facilitate storage and retrieval and avoid mutual squeezing, the existing controller structure often hangs the external protective shells side by side on the corresponding hanging frames in a hanging manner. The inner side of the hanging frame is against the wall and is set horizontally as a whole. The upper and lower parts of the hanging frame are both provided with card slots in the horizontal direction, wherein the upper card slot opens upward and the lower card slot opens downward. The back of the protective shell is provided with a hook for snapping into the upper card slot of the hanging frame and sliding along the upper card slot of the hanging frame. After sliding into place, the lower part of the protective shell is clamped to the lower card slot of the hanging frame by a clamping mechanism to prevent the protective shell from slipping forward and damaging the product.

[0003] However, in order to ensure the clamping force, the existing clamping mechanism generally adopts a more complex elastic locking mechanism, which not only has a high cost, but the unlocking device of the elastic locking mechanism is located relatively inward, and the inner side is a wall, which makes it easy to lock upwards but difficult to unlock and disassemble downwards. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a hanging controller protection shell which has a simple locking structure and is convenient to take and put.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a hanging controller protection shell, including a shell, the back of the shell is fixedly provided with at least two hooks for downwardly snapping into the upper slots of the suspension frame and sliding along the upper slots, and a limit block corresponding to the number of the hooks, the limit block is located at the lower part of the hook and supported by the bottom of the suspension frame, the back of the shell is rotatably provided with a locking block through a rotating assembly, and a rotation limit mechanism is provided between the locking block and the back of the shell, the The bottom of the locking block extends downward from the bottom of the shell to form a toggle portion. When the toggle portion is rotated to rotate the locking block to the locking position, the upper end of the locking block is clamped on the lower slot of the suspension bracket and is kept in a fixed position by the limiting action of the rotation limiting mechanism. At this time, the bottom of the toggle portion is located below the bottom of the suspension bracket. When the toggle portion is rotated to turn the locking block away from the locking position, the upper end of the locking block overcomes the limiting action of the rotation limiting mechanism and rotates downward to disengage from the lower slot of the suspension bracket.

[0006] Compared with the prior art, the advantage of the utility model is that after the shell is placed in the suspension frame, it is only necessary to rotate the locking block so that the upper end of the locking block is clamped on the lower groove of the suspension frame, and the position is fixed by the limiting action of the rotation limit mechanism, and it can cooperate with the hook to realize the clamping of the shell in the front and rear directions, preventing the shell from falling out and fixing the position of the shell, thereby effectively protecting the shell after hanging; when the shell needs to be taken out, it is only necessary to rotate the toggle part to turn the locking block away from the locking position, and the upper end of the locking block overcomes the limiting action of the rotation limit mechanism and rotates downward to disengage from the lower groove of the suspension frame, at this time, the shell can be easily moved outward along the suspension frame and taken out, and since the toggle part extends downward from the bottom of the locking block, the operator can easily rotate this part to realize the rotation of the locking block; the entire locking structure is relatively simple, easy to process and install, saving costs, and has a good fixing effect, and is convenient and labor-saving to operate.

[0007] The rotating assembly includes a screw, an inner gasket and an outer gasket, the screw is fixedly screwed into a screw hole opened at the back of the housing, the inner gasket and the outer gasket are sequentially sleeved on the screw from front to back and are located at the rear side of the housing, the locking block is provided with a rotating hole, the locking block is rotatably sleeved on the screw through the rotating hole and is rotatably pressed between the inner gasket and the outer gasket. The structure is simple and easy to install.

[0008] The outer gasket is an elastic rubber sheet with a middle portion protruding forward, and the inner gasket is a damping sheet, so that the pressing force of the locking block on the lower card slot of the suspension frame can be adjusted conveniently.

[0009] The rotation limiting mechanism includes a limiting rivet riveted on the back of the housing and a limiting hole opened on the locking block, and the limiting rivet extends into the limiting hole to limit the locking block. The design of the limiting rivet and the limiting hole greatly simplifies the required limiting structure, and both insertion and removal are very convenient.

[0010] The two sides of the locking block are bent backwards to respectively provide a first sliding guide plate and a second sliding guide plate. When the housing is pushed from one end of the hanging frame to the other end, the hanging frame drives the locking block to rotate so that the first sliding guide plate is pressed against the bottom of the hanging frame; when the housing is pulled out from the inside of the hanging frame to one end, the hanging frame drives the locking block to rotate so that the second sliding guide plate is pressed against the bottom of the hanging frame. The first sliding guide plate and the second sliding guide plate slide along the bottom of the hanging frame to prevent the locking block from getting stuck with the hanging frame during sliding and affecting the continued sliding.

[0011] One side of the toggle part is bent forward to be provided with a toggle piece, and the toggle piece is located below the shell, so that the toggle piece can be rotated by hand or tool from the front of the shell to rotate the locking block to lock or unlock.
