The present invention relates to the technical field of cabinets, in particular to a steel cable steering device, a steel cable steering system, and a lifting cabinet.
With the development of urbanization, many houses are small-sized. In order to ensure enough storage space, a hanging, automatically lifting cabinet is mounted indoors, wherein a cabinet body of the cabinet is equipped with a lifting shelf which may be lifted or lowered relative to the cabinet body and lower out from the bottom of the cabinet body.
However, in the existing lifting cabinet, a motor is used to drive the steel cable, and then the steel cable drives the lifting shelf to move. In order to save space occupied by the power mechanisms such as a motor, the power mechanism in the cabinet body is generally horizontally arranged in the middle of the cabinet body. As the power mechanism is horizontally arranged and it has a certain length, a steel cable which extends out from an outlet of the power mechanism and connects to a lifting shelf is unable to be connected to the middle part of either side edge of the lifting shelf, thereby the lifting shelf bears an unbalanced force.
Therefore, it is an objective of the present invention to provide a steel cable steering device of a lifting cabinet, which may guide the steel cable horizontal and vertical movement, and the vertical segment of the steel cable is connected to a middle of a side edge of a lifting shelf.
It is provided a steel cable steering device used for a lifting cabinet comprising a first transmission wheel and a second transmission wheel; wherein the first transmission wheel is used for horizontally turning a steel cable, the second transmission wheel is used for vertically turning the steel cable which extends out from the first transmission wheel. The steel cable extending downwardly from the second transmission wheel is connected to a middle part of a side edge of a lifting shelf.
In the steel cable steering device of the present invention, the steel cable firstly extends horizontally to the midperpendicular of a side edge of the cabinet body through the first transmission wheel, and then the steel cable extending out from the first transmission wheel is further vertically turned through the second transmission wheel, thereby the steel cable is connected to the middle part of a side edge of the lifting shelf, and the lifting shelf bears a balanced force.
Further, the steel cable between the first transmission wheel and the second transmission wheel remains horizontal.
In the steel cable steering device of the present invention, when the steel cable is sliding on the first transmission wheel or the second transmission wheel, it slides in the same direction with a groove in the first transmission wheel or second transmission wheel respectively by keeping the steel cable between the first transmission wheel and the second transmission wheel horizontal, thereby avoiding a situation that the steel cable is disengaged from the first or second transmission wheel.
Specifically, the steel cable steering device further comprises a housing, and a first slot for mounting the first transmission wheel, a second slot for mounting the second transmission wheel, and a first channel for communicating with the first slot and second slot are configured in the housing.
In the steel cable steering device of the present invention, the first slot and the steel cable outlet of the power mechanism of the lifting cabinet are located in a same plane, so that the steel cable between the first transmission wheel and the power mechanism keeps horizontal or nearly horizontal, thereby avoiding that a component force in another direction is generated to reduce the pull force on the lifting shelf due to the sideling configuration of the steel cable.
In the steel cable steering device of the present invention, a guide plate is configured in both the first slot and the second slot in the housing, wherein at least one guide block is configured on the guide plate, so that at least two guide grooves are formed between the first transmission wheel, the guide plate, and the guide block, and at least two guide grooves are formed between the second transmission wheel, the guide plate and the guide block. These guide grooves guide the two steel cables extending from the first transmission wheel or the second transmission wheel, to prevent the steel cables from shifting after the steel cable is turned, thereby ensuring that the steel cables will not be entangled.
It is another objective of the present embodiment to disclose a lifting cabinet, comprising a cabinet body, a lifting shelf movable in the cabinet body, a power mechanism for driving the lifting shelf and a steel cable steering device as above mentioned.
It is a further objective of the present embodiment to disclose a steel cable steering system of the lifting cabinet, comprising two groups of the steel cable steering device as above mentioned.
The two groups of the steel cable steering device are respectively disposed on both sides of the inside of the lifting cabinet body.
Further, the two groups of the steel cable steering devices are coupled to the two groups of steel cables extending out from the power mechanism of the lifting cabinet, and the two groups of steel cables are in the same plane.
In one group of the steel cable steering device, a first angle is formed in a horizontal direction between the steel cable extending into the first transmission wheel and the steel cable extending out from the first transmission wheel.
In another group of the steel cable steering device, a second angle is formed in a horizontal direction between the steel cable extending into the first transmission wheel and the steel cable extending out from the first transmission wheel.
The first angle is unequal to the second angle.
As the cabinet body has a tight space for mounting the power mechanism, the two groups of steel cables extending out from the power mechanism are disposed in a same horizontal plane, that is the two groups of steel cables are separated horizontally in a certain distance.
The steel cable steering system of the present invention comprises two groups of the steel cable steering device, wherein in one group of the steel cable steering device, a first angle is formed in a horizontal direction between the steel cable extending into the first transmission wheel and the steel cable extending out from the first transmission wheel; and in another group of the steel cable steering device, a second angle is formed. One of the groups of steel cables has a larger turning angle by making the first angle unequal to the second angle, thereby both the two groups of steel cables separated horizontally from each other in a distance are able to be connected to the middle part of a side edge of the lifting shelf.
It is a further objective of the present embodiment to disclose a lifting cabinet, comprising a cabinet body, a lifting shelf movable in the cabinet body, a power mechanism for driving the lifting shelf and a steel cable steering system as above mentioned.
For a better understanding and practice, the present invention will be described in detail with reference to accompanying figures.
