The following describes in detail the procedure of locking and unlocking the door panel by the anti-separation device of the present invention.
First, as shown in fig. 1, the retaining plate 324 is fixed to the door panel 2, and the retaining device 3 is fixed to the cabinet 1 by the fixing base 31.
Force along the axial direction of the stopper 321 is applied to the two blocking sheets 325, so that the stopper 321 approaches the cabinet 1 along the axial direction, and the stopper 323 is separated from the long groove 328, so that the stopper 321 can rotate.
The stopper 321 is rotated to extend the two blocking pieces 325 in a direction parallel to the length direction of the insertion hole 326, and at this time, the extending direction of the blocking pieces 325 is the X-axis direction shown in fig. 2, and since the length of the insertion hole 326 is greater than the distance between the end portions of the two blocking pieces 325, the blocking pieces 325 can pass through the insertion hole 326, i.e., the anti-separation plate 324 can be matched with the stopper 321.
At this time, the anti-falling stopper 32 is at the second position, as shown in fig. 2, at this time, the door panel 2 and the cabinet 1 are in an unlocked state.
Next, the stopper 321 is rotated to move from the second position to the first position.
Specifically, the stopper 321 is rotated by 90 °, so that the extending direction of the two stoppers 325 becomes perpendicular to the longitudinal direction of the insertion hole 326, the extending direction of the stoppers 325 being the Y-axis direction shown in fig. 4, and the two stoppers 325 cross the width direction of the insertion hole 326, engage with the insertion hole 326, and do not fall out of the insertion hole 326.
When the stopper 321 rotates 90 °, the orientation of the long groove 328 is changed, that is, the length direction of the long groove 328 is changed from the Y-axis direction shown in fig. 2 to the X-axis direction shown in fig. 4, at this time, the stopper 321 moves in a direction away from the cabinet 1 under the action of the elastic member 322, so that the stopper 323 is engaged in the long groove 328 to limit the rotation of the stopper 321.
In the first position, as shown in fig. 4, the two blocking pieces 325 cross the width direction of the insertion hole 326 and engage with the insertion hole 326, so that the separation preventing plate 324 cannot be separated from the cabinet 1, and further, the stopper 323 engages with the long groove 328, so that the stopper 321 cannot rotate, thereby maintaining the locked state of the door panel 2 and the cabinet 1.
According to the utility model discloses a second aspect, the utility model provides an electric appliance cabinet, it includes foretell anticreep device 3 and the cabinet body 1 and the door plant 2 that link to each other with anticreep device 3 respectively.
Further, as shown in fig. 1, the electric appliance cabinet further includes a door lock 5, the door panel 2 is connected with the cabinet body 1 through the door lock 5 to realize primary anti-falling, and secondary anti-falling can be realized through the anti-falling device, so that the connection between the door panel 2 of the electric appliance cabinet and the cabinet body 1 is more stable.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
