Referring to Figures 1 to 10, the present invention provides a safety lock device for a cabinet. As shown in FIGS. 1, 2, 3, and 4, the safety lock device for the cabinet provided by the present invention basically includes a cabinet body 10, a sliding door 20, and a safety lock device 30. Among them, the cabinet body 10 may be, for example, a cooker storage cabinet or a cabinet-type dish dryer, but it is not limited to this. The safety lock device 30 of this embodiment is installed between the sliding sliding door 20 and the cabinet body 10 to prevent children from pulling the sliding sliding door 20 due to curiosity, causing the sliding sliding door 20 to slide open and easily escape suddenly The risk of getting hot from the heat.

The following will further introduce the structure of each component of the safety lock device of the cabinet of this embodiment, and explain the connection relationship between the various components of the safety lock device of the cabinet of this embodiment in due course.

As shown in FIGS. 3 and 4, the sliding door 20 of this embodiment is slidably installed on the cabinet body 10 to open or close the working space in the cabinet body 10. The sliding door 20 can be slidably installed on the cabinet body 10 through the sliding cooperation of existing sliding rails, sliding grooves, or pulleys. The sliding door 20 of this embodiment is provided with a handle 21 to facilitate the pulling of the sliding door 20 so that the sliding door 20 can slide along a sliding direction A.

The safety lock device 30 of this embodiment basically includes a hidden actuator 31, a rotating fastener 32, and a fixed fastener 33.

Furthermore, the hidden actuator 31 of this embodiment is located in a space G formed between the handle 21 and the front side of the sliding door 20, as shown in FIG. In the space 21, the hidden actuator 31 is hidden in the space G. Furthermore, the handle 21 of the present embodiment has a U-shaped structure, and the space G is formed between the U-shaped handle 21 and the sliding door 20. Furthermore, the hidden actuator 31 of this embodiment can be hidden in the space G in the shape of a horizontal rod, and has a short size, at least less than a quarter of the length of the handle 21, and is close to the far left of the handle 21 Or the rightmost end, so that when the child directly pulls the handle 21, the hidden actuator 31 will not be touched or found.

The rotating fastener 32 of this embodiment is connected to the hidden actuator 31, and the hidden actuator 31 and the rotating fastener 32 are respectively located on the front and rear sides of the sliding door 20 as shown in FIG. 3. In addition, when the hidden actuator 31 is driven by an external force to rotate relative to the sliding door 20, it can drive the rotating fastener 32 to rotate. Furthermore, the rotating fastener 32 can be connected to the hidden actuator 31 through a shaft 34 passing through the sliding door 20. The shaft 34 can be an integral part with the rotating fastener 32, and the shaft 34 can also be an integral part with the hidden actuator 31, without limitation.

Furthermore, in order to make the hidden actuator 31 and the rotating fastener 32 automatically reset at the same time after the external force driving the hidden actuator 31 disappears, a return spring 35 is further sheathed on the shaft 34 of this embodiment. , Used to store an elastic potential energy when the hidden actuator 31 is driven by an external force to rotate relative to the sliding door 20, so that after the external force disappears, the hidden actuator 31 and the rotating fastener 32 can pass through the elastic potential energy of the return spring 35 The release and automatic reset at the same time. The return spring 35 of this embodiment can be realized by a torsion spring.

The fixing fastener 33 of this embodiment is arranged in the cabinet body 10 as shown in FIG. 4. Furthermore, as shown in FIG. 6, the fixing fastener 33 of this embodiment has a fixing portion 331 fixed in the cabinet body 10 and an elastic fastener portion 332 extending from the fixing portion 331. The rotating fastener 32 can be pressed against the rear side of the elastic fastener 332, so that the elastic fastener 332 is positioned between the front side of the rotating fastener 32 and the rear side of the sliding door 20 to resist the rotating fastener 32, thereby The sliding door 20 cannot be slid and opened to close the working space in the cabinet body 10. When the hidden actuator 31 rotates relative to the sliding door 20 to drive the rotating fastener 32 to rotate by an angle, the elastic fastener 332 is rotated out (As shown in FIG. 7), so that the sliding door 20 can slide in the sliding direction A (as shown in FIG. 4) to open the working space in the cabinet body 10.

Furthermore, the front side of the elastic buckle portion 332 of this embodiment is formed with a guiding inclined surface. When the sliding sliding door 20 is opened, the sliding sliding door 20 can be slid in the sliding direction B by gently pushing the sliding door 20 ( 4), the rotating fastener 32 is pushed against the guiding inclined surface 3321 of the elastic buckle portion 332 (as shown in Figs. The movable fastener 32 is pressed against the rear side of the elastic fastener 332 (as shown in FIG. 10), so that the elastic fastener 332 is located between the front side of the rotating fastener 32 and the rear side of the sliding door 20, and the elastic fastener The 332 resists the rotating fastener 32, so that the sliding door 20 cannot be slid and opened, which can prevent children from pulling the handle 21 arbitrarily and causing the sliding door 20 to slide open and causing accidents.

In addition, when the sliding door 20 is to be slid and opened, the hidden actuator 31 can be pressed down when the finger reaches into the space G to pull the handle 21, so that the hidden actuator 31 rotates relative to the sliding door 20 to pass through the shaft The rod 34 drives the rotating fastener 32 to rotate by an angle to rotate out of the rear side of the elastic fastener 332, so that the sliding door 20 can be slid and opened. Therefore, the sliding door 20 can be conveniently pulled by pressing the hidden actuator 31 when the handle 21 is pulled.

Furthermore, after the sliding door 20 is slid and opened, the hidden actuator 31 and the rotating fastener 32 can be automatically reset at the same time through the release of the elastic potential energy of the return spring 35, and in order to make the rotating fastener 32 rotate and reset Without excessive rotation, the safety lock device 30 of this embodiment further includes a stop mechanism 36.

Furthermore, the stop mechanism 36 of this embodiment includes a stop member 361 fixed to the rotating fastener and a stop protrusion 362 fixed to the rear side of the sliding door 20. The stopper 361 can abut against the stop protrusion 362 as the rotating fastener 32 rotates, which can effectively ensure that the rotating fastener 32 does not rotate excessively when the rotating fastener 32 is automatically reset.

Furthermore, the stopper 361 of this embodiment can be integrally formed by a piece of metal sheet, a locking piece 3611 locked to the rotating fastener 32 and a stopper piece formed by bending and extending the locking piece 3611 3612. In addition, the stop protrusion 362 can be realized by a stop screw that is locked into the rear side of the sliding door 20.

In summary, the safety lock device of the cabinet provided by the present invention adopts the hidden design of the hidden actuator 31 in the space G formed between the handle 21 and the front side of the sliding door 20, so that children can When the handle 21 is pulled directly, the hidden actuator 31 will not be touched or found. In addition, when the rotating fastener 32 is pressed against the rear side of the elastic fastener 332, the elastic fastener 332 is positioned between the front side of the rotating fastener 32 and the rear side of the sliding door 20 to resist the rotating fastener. 32, so that the sliding sliding door 20 cannot be slid and opened, which can prevent children from pulling the handle 21 arbitrarily and causing the sliding sliding door 20 to slide open and causing accidents. Moreover, when the hidden actuator 31 rotates relative to the sliding door 20 to drive the rotating fastener 32 to rotate by an angle and turn out the rear side of the elastic buckle 332, the sliding door 20 can be easily and conveniently pulled to make the sliding The door 20 slides to open the working space in the cabinet body 10.
