Description of the embodiments

Referring to fig. 1, the folding bracket comprises a bracket body 1, wherein the middle part of the bracket body 1 is movably connected with one end of a swing arm 2 through a first rotating shaft, one end of the bracket body 1 is a constraint end 3, the constraint end is connected to a sliding block 5 through a second rotating shaft, the other end of the bracket body 1 is a free end 4, and the sliding block 5 is arranged on a sliding rail 6. The expansion or folding of the bracket body 1 is realized by taking the swing arm 2 as a fulcrum completely and by the swing of the swing arm 2 and the rotation between the bracket body 1. The folding bracket can be unfolded by applying an outward pulling force to the free end 4 or by the sliding block 5. The restraint end 3 of the bracket body 1 moves towards the direction of the swing arm 2, and the free end 4 of the bracket body 1 swings outwards, so that the included angle between the bracket body 1 and the sliding rail 6 is gradually increased until the bracket body is vertical. The free end 4 is pushed or driven by the sliding block 5 by folding, so that the constraint end 3 moves reversely, and the free end 4 of the bracket body 1 swings inwards until the bracket body 1 is parallel to the sliding rail 6. In order to increase the safety of the opening or folding operation of the bracket body 1, the output torque of the motor can be adjusted to prevent the bracket body 1 from falling instantly when the stress is lost. Only the free end 4 swings to a smaller extent during the operation of the folding stand, so that it requires less space for its operation than a living hinge, thereby being more suitable for use in a narrow space. Meanwhile, the driving device can be used for realizing automatic unfolding and folding, the driving device is easy to realize hidden design, the driving device cannot be exposed outside the folding bracket, and the folding bracket is more attractive and saves space.

In order to realize the automatic operation of the folding bracket, the sliding block 5 can be connected with the driving mechanism 7, and the driving mechanism 7 drives the sliding block 5 to slide along the sliding rail 6. The driving mechanism 7 may be implemented in various manners, such as a manner of matching a screw rod with a nut, a manner of expanding and contracting a cylinder, and the like. The preferable scheme of the utility model is that a synchronous belt is adopted, the synchronous belt is designed along a slide rail 6, two ends of the synchronous belt are respectively connected to two ends of a slide block 5, then the synchronous belt is meshed with a synchronous belt wheel, and the synchronous belt wheel is arranged on a driving motor. The driving motor drives the synchronous belt to roll, thereby pulling the sliding block 5 to slide along the sliding rail 6. Compared with other driving modes, the mechanism is more compact and reliable and is more suitable for being used in narrow spaces.

The folding bracket can be applied to various folding furniture. The present utility model provides an example of applying the present folding stand to a folding table, referring to fig. 2 and 3. The folding table is mounted on the wall surface through a sliding rail 6. The table top 8 is arranged on the bracket body 1, so that the folded table after being unfolded is more stable and reliable when being used, and the free end 4 of the bracket body 1 is provided with the supporting leg 9. Under the folded state, the folding table is parallel to the wall surface and is attached to reduce the occupied area of the folding table. In the unfolded state, the folding table is vertical to the wall surface, and then is unfolded through the supporting legs 9 to be abutted against the ground to support the free end 4, so that the table top 8 for use is formed. The support leg 9 is movably connected with the free end 4 of the support body 1 through a third rotating shaft, and an electric telescopic unfolding device 11 is arranged between the support leg 9 and the support body 1 for realizing automatic unfolding and folding of the support frame.

In order to enable the folding table to be hidden in the wall surface, mounting holes can be dug in the wall body, but the operation is relatively troublesome. The cabinet body 12 can also be arranged on the wall surface, the folding table is embedded in the cabinet body 12, the purpose of hiding is achieved, and the whole cabinet is more attractive. At the same time, the table top 8 can also form a cabinet door of the cabinet body 12, and the cabinet can be seen as a decorative cabinet after being folded. To fully utilize the space in the cabinet 12, shelves 10 for holding objects are provided on both sides of the folding table in the cabinet 12.
