DETAILED DESCRIPTION

[0019] The embodiment of the present application discloses a folding cabinet door, in which a support assembly 4 is arranged at the bottom end of multiple door panels 1, and the support assembly 4 includes a support rod 41 and a driving member 43 that drives the support rod 41 to move back and forth vertically. A vertical installation groove is opened on the bottom surface of the door panel 1, and the support rod 41 is slidably connected along the long side direction of the installation groove. A ball 42 is rotatably arranged at the bottom end of the support rod 41, and the ball 42 is in contact with the ground to reduce the friction force when the door panel 1 moves, and at the same time cooperates with the support rod 41 to support the door panel 1, so that the door panel 1 is not easy to fall to a certain extent.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1 , Figure 2 A folding cabinet door includes multiple door panels 1, and the adjacent sides of the multiple door panels 1 are hinged. A hanging rail 2 is installed on the top of the door panel 1, and multiple rollers 3 are slidably connected in the hanging rail 2. The multiple rollers 3 are fixedly connected to the corresponding positions of the top ends of the door panels 1, and a supporting assembly 4 is arranged at the bottom ends of the multiple door panels 1. The supporting assembly 4 includes a supporting rod 41 and a driving member 43 that drives the supporting rod 41 to reciprocate vertically. A vertical mounting groove is opened on the bottom surface of the door panel 1, and the supporting rod 41 is slidably connected along the long side direction of the mounting groove. A ball 42 is rotatably arranged at the bottom end of the supporting rod 41, and the ball 42 is in contact with the ground to reduce the friction force when the door panel 1 moves, and at the same time cooperates with the support rod 41 to support the door panel 1, so that the door panel 1 is not easy to fall to a certain extent. At the same time, the driving member 43 can make the ball 42 stored in the door panel 1, which is convenient for handling the hygiene of the bottom of the door panel 1.

[0022] Reference Figure 2 , Figure 3 The driving member 43 includes a gear 431. A chamber 11 is provided in the door panel 1. The mounting groove is connected to the chamber 11. The gear 431 is rotatably arranged in the chamber 11. A tooth groove 411 is provided on the side of the support rod 41 close to the gear 431. The gear 431 meshes with the tooth groove 411. A handle 44 is provided on the door panel 1 to drive the gear 431 to rotate. The gear 431 is manually driven to rotate by the handle 44, so that the support rod 41 can move back and forth vertically.

[0023] Reference Figure 2-Figure 5 The handle 44 includes a rotating column 441 and a grip 442 for manually driving the gear 431 to rotate. The rotating column 441 is coaxially arranged with the gear 431, and the rotating column 441 is fixedly connected with the gear 431. The rotating column 441 is rotatably connected with the corresponding position of the door panel 1. A prismatic slide groove 4411 is provided at the end of the rotating column 441 away from the gear 431, and a slider 443 is slidably connected in the slide groove 4411. The grip 442 is fixedly connected to the end of the slider 443 away from the gear 431. A groove 12 matching the shape of the grip 442 is provided on the door panel 1, and the grip 442 and the groove 12 are movable. When the handle 442 is inserted into the groove 12, the side of the handle 442 away from the slider 443 can be in the same horizontal plane with the side of the door panel 1 close to the handle 442, so that the handle 442 can be stored in the door panel 1, so that the two adjacent door panels 1 can fit together and be more beautiful. A pit 4421 is provided on the side of the handle 442 away from the rotating column 441, and a pull rod 444 is fixedly installed at the opening position of the pit 4421. When pulling out the handle 442 stored in the door panel 1, put your fingers into the pit 4421, pull out the pull rod 444, and pull out the handle 442.

[0024] Reference Figure 4 , Figure 5 The handle 442 is cylindrical, and a plurality of arc-shaped protrusions 445 are fixedly connected on the circumferential surface of the handle 442. The edges of two adjacent arc-shaped protrusions 445 are connected. The groove 12 is also cylindrical, and a limit ring 446 is fixedly installed in the groove 12. A plurality of embedded grooves matching the shapes of the plurality of arc-shaped protrusions 445 are provided on the inner side of the limit ring 446. The height of the support rod 41 is adjusted by rotating the handle 442 so that the ball 42 fits the ground, and then the position of the limit ring 446 is adjusted. , so that the arc-shaped protrusion 445 corresponds to the embedded groove position on the limiting ring 446, and then the limiting ring 446 is fixedly installed in the groove 12. At this time, the side of the handle 442 away from the slider 443 can be in the same horizontal plane with the side of the door panel 1 close to the handle 442. The handle 442 is inserted into the limiting ring 446 to prevent the handle 442 from rotating in the groove 12, resulting in the support rod 41 having no supporting force. At the same time, the arc-shaped protrusion 445 increases the friction between the hand and the handle 442, and it is not easy to scratch the hand.

[0025] The working principle of the embodiment of the present application is: after hanging the door panel 1 on the hanging rail 2, put your finger into the pit 4421 to locate the pull rod 444, pull the pull rod 444 outward, pull out the handle 442, manually rotate the handle 442 to move the support rod 41 toward the ground until the ball 42 is in contact with the ground, and then adjust the position of the limiting ring 446 so that the arc-shaped protrusion 445 corresponds to the position of the embedded groove on the limiting ring 446, and then fix the limiting ring 446 in the groove 12, and then insert the handle 442 into the limiting ring 446, so that the support rod 41 supports the door panel 1 from the bottom, which makes the door panel 1 not easy to fall to a certain extent.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0027] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
