Detailed Description
The invention will be further described with reference to the accompanying drawings in which: as shown in the figure, a locking piece 4 and an unlocking piece 5 are arranged in the shell, and the locking piece comprises a locking position and an unlocking position, wherein the locking position is used for being in limit fit with a containing groove 11 of the installation cabinet to prevent the shell from being taken out of the containing groove, and the unlocking position is used for enabling the shell to be taken out of the containing groove after being pushed by the unlocking piece. The locking piece is movably connected with the shell, specifically can be in rotating or sliding connection, when the locking piece is located at a locking position, the locking piece is in limit fit with the cabinet body, so that the shell cannot be taken out of the containing groove, and when the locking piece is located at an unlocking position, the shell can be taken out of the containing groove.
In this embodiment, the locking member is rotatably disposed within the housing as shown. The shaft hole may be provided in the locking member by providing a rotating shaft in the housing.
In this embodiment, as shown in fig. 1 to 4, the outer wall of the housing is provided with a through groove 21, the accommodating groove is provided with a communicated groove 12, and when the locking member is in the locking position, the bottom of the locking member passes through the through groove and is disposed in the groove. The bottom of the locking piece is arranged in the groove, and at the moment, if the shell is pulled outwards, the locking piece can be abutted against the inner wall of the groove to enable the locking piece not to be pulled out, so that locking is realized.
In this embodiment, as shown in the figure, the locking device further includes an elastic resetting member 41 for applying a force to place the locking member in the locking position. For resetting, the elastic resetting piece can be a torsion spring or a spring, and the force is applied to the back of the upper end of the locking piece, namely, the force is applied in the counterclockwise direction in fig. 4.
In this embodiment, as shown, the unlocking member is slidably engaged with the housing, and the unlocking member includes a first position and a second position for pushing the locking member to rotate so that the bottom of the locking member is away from the groove. The unlocking piece adopts a linear sliding structure, can also use modes such as rotation and the like, and has a simple sliding structure.
In this embodiment, as shown in fig. 8, a sliding groove 22 is formed on the housing, and the unlocking member is slidably engaged with the sliding groove, and the unlocking member is partially disposed outside the housing. The part is arranged outside the shell and used for pushing unlocking. The bottom of the unlocking member has a stopper plate 51 which cooperates with the stopper 18 in the housing to prevent it from falling out of the housing.
In this embodiment, as shown, the outer wall of the housing is provided with a hinge-engaging pull ring 13, which includes a push rod 131 for pushing the unlocking member to the second position when the pull ring is rotated. Further, the pull ring rotates to the position of leaving the casing, and its push rod promotes the deblocking piece in order to realize the unblock, puts down the pull ring after target in place, leaves the deblocking piece, and the effect of locking piece elastic component is got back to first latched position again to the locking piece backstep the deblocking piece and get back to first position.
In this embodiment, as shown in fig. 6, a handle 6 is further disposed on the housing, the handle includes a switching-on position and a switching-off position, a boss 43 is disposed on the locking member, and when the handle is at the switching-on position and the locking member is at the locking position, the boss and the handle are in blocking fit to make the locking member non-rotatable. When the handle was closed a floodgate, this boss can support and press in the outer wall of this handle, at this moment, even promote the also unable unblock of unblock piece, when the handle was closed a floodgate promptly, can't install the cabinet internal with the casing, and it is safer to use.
In this embodiment, as shown in fig. 5, a notch 61 is formed on the handle, when the handle is in the brake separating position, the boss corresponds to the notch, and the locking member is rotatable. When only the handle is in the opening position, the opening can leave a space for the rotation of the boss, and the locking piece can rotate to unlock at the moment, so that the use is safe.
In this embodiment, as shown in fig. 1, the installation cabinet comprises a cabinet body 1, in which a receiving groove 11 for installing the switch device as described above is provided.
