Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

One aspect of the present application provides a flipping positioning mechanism for flipping and supporting the panel 62 of the cabinet. Referring to fig. 1, fig. 1 shows a schematic structural diagram of an overturning positioning mechanism in an embodiment of the present invention. Specifically, the roll positioning mechanism of an embodiment includes a track member 10, a link 30, a guide member 20, and an elastic member 40.

The track member 10 is fixedly disposed in the cabinet body 61, and the track member is provided with a track groove 11 extending in a direction close to the panel 62 of the cabinet. The first end of the link 30 is slidably engaged with the track groove 11, and the second end of the link 30 is rotatably connected with the panel 62, so that the panel 62 is driven to open or close by sliding the link 30 in the track groove 11.

Further, the guide member 20 is rotatably coupled to the track member 10, and the guide member 20 has a stop position in which at least a part of a projection of the guide member 20 on the track member 10 overlaps the track groove 11, and an escape position in which the link 30 is engaged with the guide member 20 when the panel 62 is opened to a predetermined angle. In the retracted position, the projection of the guide 20 on the trajectory part 10 does not overlap or slightly overlaps the trajectory groove 11, so that the guide 20 retracts the connecting rod 30. Further, in the initial state, the guide 20 is in the stop position, so that when the panel 62 is opened to a predetermined angle, the guide 20 can abut against the link 30. During closing of the panel 62, the panel 62 is pushed by an external force, and then the link 30 transmits the pushing force to the guide 20, thereby rotating the guide 20 to the escape position.

Further, one end of the elastic member 40 is connected to the guide member 20, and the other end of the elastic member 40 is connected to the track member 10, and the elastic member 40 acts to resist the gravity of the panel 62 to maintain the guide member 20 at the stop position. Preferably, the elastic member 40 is a tension spring.

Specifically, referring to fig. 2, in the process of opening the panel 62, the panel 62 rotates around the cabinet body 61 under the action of an external force, so as to drive the first end of the connecting rod 30 to move from one end of the track groove 11 far from the panel 62 to one end of the track groove 11 close to the panel 62, at this time, the guide 20 is located at the stop position, when the panel 62 is opened to a preset angle, the guide 20 can abut against the connecting rod 30, at this time, the pushing force of the connecting rod 30 on the guide 20 is slightly greater than the supporting force of the elastic member 40, but is insufficient to overcome the pulling force of the elastic member 40, so as to stop the panel 62 at the preset angle, and avoid the panel 62 from automatically closing under the action of its own gravity. Note that, the angle of the panel 62 being locked is related to the position of the guide member 20, and the closer the guide member 20 is to the panel 62, the larger the angle of the panel 62 being locked is, and the farther the guide member 20 is from the panel 62, the smaller the angle of the panel 62 being locked is. Further, the relationship between the locking angle of the panel 62 and the position of the guide 20 can be obtained through a limited number of tests and calculations, which are not described herein. The skilled person can set the above-mentioned preset angle according to actual requirements, and the position of the guide 20 is designed according to the required preset angle.

Further, referring to fig. 3, in the process of closing the panel 62, the panel 62 is pushed by an external force to rotate toward the direction close to the cabinet body 61, and then the link 30 can transmit the pushing force to the guide 20, so that the guide 20 rotates to the escape position against the elastic force of the elastic member 40. At this time, the guide 20 can not stop the link 30 any more, and the link 30 can move along the track groove 11 to the end of the track groove 11 far away from the panel 62 under the action of external force, and finally the panel 62 is closed.

The turning positioning mechanism is characterized in that the guide member 20 is rotatably arranged on the track member 10, the guide member 20 is provided with a blocking position and an avoiding position, at least part of projection of the guide member 20 on the track member 10 is overlapped with the track groove 11 at the blocking position, so that when the panel 62 is opened to a preset angle, the guide member 20 can be abutted against the connecting rod 30 to block and stop the panel 62 at the preset angle, and the panel 62 is prevented from being automatically closed under the action of self gravity. And during closing the panel 62, the link 30 can transmit the pushing force to the guide 20 by pushing the panel 62 with one hand, thereby rotating the guide 20 to the escape position against the elastic force of the elastic member 40. At this time, the guide 20 can not stop the link 30 any more, and the link 30 can move along the track groove 11 to the end of the track groove 11 far away from the panel 62 under the action of external force, and finally the panel 62 is closed. The turnover positioning mechanism can be operated by a single hand, so that the panel 62 can be easily opened or closed, the panel 62 can be temporarily stopped at a preset angle after being opened, and subsequent maintenance of parts in the cabinet is facilitated.
