Handle device for a modularized casing
A handle device for a modularized casing is composed of a rectangular inner casing; a handle; a shaft pin which is flexibly connected to the pivoting hole of casing and the pivoting hole of handle being rotated against the shaft pin; and an outer casing, the front sliding wall/rear sliding wall can be frictionally sliding and be exerting a force on a circumferential surface of the pillar. The handle can be moved into or out of an emplacing space, so as to prevent the inner casing from being dropped on a ground surface due to an excessive exertion of force upon pulling out the inner casing from the emplacement sink. In addition, a large vibration force will not be created, such that the handle can be tightly locked and positioned on the inner casing, after inserting the inner casing into the emplacement sink.
1. A handle device for a modularized casing comprising a rectangular, modularized inner casing, a surface of which is provided with a pivoting hole; a handle, a front end of which is formed with a groove having a pivoting hole on a surface at its rear side, and having a front sliding wall and a rear sliding wall; a projection piece in an extended shape which is located at a side of an outer end of the handle; a projection body of a smaller outer diameter which is formed at an outer end of the projection piece and a longitudinal projection part which is formed at an inner side of the projection piece; an outer sleeve, an interior of which is provided with a plate-shape groove and a cylindrical groove, both of which are interconnected, and a side edge of the outer sleeve being extended into a hollow through-slot and a hook with the through-slot providing for a transfixing of the projection part; a spring which is inserted into the cylindrical groove and a connection end of which is sheathed to the projection body with the projection piece being transfixed into the plate-shape groove; a hook which can be emplaced in the positioning hole and can be locked to an inner wall of positioning hole; a shaft pin which is flexibly to the pivoting hole of inner casing and the pivoting hole of handle with the handle being rotated against the shaft pin; an outer casing which is provided with at least more than one emplacement sink, with a pillar being located on a wall of the emplacement sink and an emplacing space located between the emplacement sink and the inner casing; when the inner casing is inserted into or pulled out from the emplacement sink, the front sliding wall and rear sliding wall of the groove are able to be frictionally sliding and exerts a force on a circumferential surface of the pillar which can be located inside or outside the groove; the handle is able to be moved into or out of the emplacing space.
2. The handle device for a modularized casing according to claim 1 , wherein a first projection body is located on a surface of inner casing and on a side surface of tail end of handle, and a side wall of tail end of handle can be abutted at a side edge of first projection body, so as to form an interface of force exertion.
3. The handle device for a modularized casing according to claim 1 , wherein a second projection body is located on a surface of inner casing and on a side surface close to a front end of handle, a notch is located on a side wall of handle, and an inner wall of notch can be abutted at a side wall of second projection body.
