In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in fig. 1-4, the utility model provides a folding support, include: the linkage mechanism 1 comprises two linkage rods 11, wherein the two linkage rods 11 are mutually crossed and hinged through a first hinge shaft; the two linkage rods 11 are intersected at the middle points of the two linkage rods, the two support mechanisms 2 are arranged on the two sides of the linkage mechanism 1 in a mirror image mode, and each support mechanism 2 comprises an upright rod 21, a sliding sleeve 22, a connecting head 23 and two inclined support mechanisms 24; the sliding sleeve 22 is slidably sleeved on the vertical rod 21, the upper end of one linkage rod 11 is hinged with the sliding sleeve 22 through a second hinge shaft, and the lower end of the other linkage rod 11 is hinged with the lower end of the vertical rod 21 through a third hinge shaft; the inclined strut mechanism 24 comprises an inclined strut 241 and an underframe rod 242, the upper end of the inclined strut 241 is hinged to the sliding sleeve 22 through a fourth hinge shaft, the lower end of the inclined strut 241 is hinged to one end of the underframe rod 242 through a sixth hinge shaft, the other end of the underframe rod 242 is hinged to the connector 23 through a fifth hinge shaft, and the lower end of a linkage rod 11 is hinged to the connector 23 through a seventh hinge shaft.

The two diagonal bracing mechanisms 24 in each support mechanism 2 are plane-symmetric about a first plane, which is perpendicular to the seventh hinge axis.

The folding support further comprises a leg rest mechanism, the leg rest mechanism comprises two straight rods 121, and the middle parts of the two straight rods 121 are hinged through an eighth hinge shaft.

The first end portions of the two straight rods 121 are respectively connected with the diagonal braces 241 of the two diagonal brace mechanisms 24 in a universal manner to a first point, and the two first points are located on the same side of the first plane, and the first point is close to the lower end of the diagonal brace 241. The straight rod 121 can rotate in any direction around the first point.

The specific mode of universal connection of the straight rod 121 and the diagonal bar 241 is as follows: a first point of the diagonal lever 241 is hinged to the connecting member 123 through a ninth hinge shaft. The first end of the straight rod 121 is provided with a spherical head, a cavity suitable for containing the spherical head is arranged inside the connecting piece 123, a circular through hole communicated with the cavity and an external space is further formed in the connecting piece 123, and the diameter of the circular through hole is smaller than that of the spherical head. The spherical head is rotatably arranged in the cavity, and the straight rod 121 is positioned outside the cavity. Therefore, the first end of the straight rod 121 and the connecting piece 123 form a ball-and-socket connection, multi-directional rotation of the straight rod 121 relative to the connecting piece 123 is achieved, meanwhile, the connecting piece 123 is hinged to the inclined supporting rod 241, and the rotation range of the straight rod 121 is further increased.

It should be noted that the positions of the two first points are not limited to the two diagonal braces 241, but may be on the two bottom bracket rods 242, and accordingly, the connecting member 123 is hinged at the first point on the bottom bracket rod 242 through the ninth hinge shaft.

Among these, the axes of the first hinge shaft, the second hinge shaft, the third hinge shaft and the seventh hinge shaft are parallel to each other; the axes of the fourth articulated shaft, the fifth articulated shaft, the sixth articulated shaft and the ninth articulated shaft are parallel to each other; the eighth hinged shaft and the first hinged shaft are positioned on the same plane; and the included angle between the second hinge shaft and the fourth hinge shaft is not 0. The lower end of the diagonal brace 241 is also provided with a leg for bracing the ground.

The folding bracket also comprises at least one locking mechanism, and each locking mechanism corresponds to one sliding sleeve 22;

when the linkage 1 and the two support mechanisms 2 are fully deployed, the locking mechanism can prevent the sliding sleeve 22 corresponding thereto from sliding up along the upright rod 21. The complete opening here means that the link mechanism 1 is in the maximum state and cannot be opened any more, and the support mechanism 2 is in the same state as the link mechanism 1.

The locking mechanism comprises a locking pin 6, and a through pin hole 61 is formed in the upright rod 21; the through pin hole 61 is defined as a through hole penetrating the upright rod 21, and the locking effect is relatively good.

When the linkage mechanism 1 and the two support mechanisms 2 are completely unfolded, the through pin hole 61 is located at the upper part of the sliding sleeve 22, and the locking pin 6 is inserted into the through pin hole 61. It is noted that the through-pin hole 61 is located at the upper part of the sliding sleeve 22, which means that when the locking pin 6 is inserted into the through-pin hole 61, the sliding sleeve 22 cannot slide up along the upright rod 21 because of the body of the locking pin 6, i.e. the integral linkage mechanism 1 and the support mechanism 2 cannot be folded. Certainly, in order to facilitate the insertion of the locking pin 6, when the locking pin 6 is inserted into the through pin hole 61, a certain gap may still exist between the body of the locking pin 6 and the upper surface of the sliding sleeve 22, and the existence of the gap only enables the sliding sleeve 22 to move up slightly.

One end of the locking pin 6 is fixed with a circular buckle 7. The arrangement of the ring buckle 7 is convenient for the pulling and inserting of the locking pin 6, and can prevent the locking pin 6 from being inserted too deeply to cause one head part of the locking pin to fall into the inner cavity of the upright rod 21, thereby causing the whole locking pin to fall into the inner cavity. Here, the locking pin 6 is in a close fit with the through-pin hole 61.

Of course, the locking pin 6 can be connected to the sliding sleeve 22 via a connecting line for easy carrying, and thus, the locking pin is prevented from being lost. Of course, the connection form is not exclusive, and it can be inserted into the sliding sleeve 22, and the connection can also be realized by a soft connection line. The locking pin 6 can also be movably suspended on the sliding sleeve 22 by a ring, so that the locking pin cannot be lost.

The end of the bottom frame rod 242 is hinged with the connector 23 through a fifth hinge shaft; in the same supporting mechanism 2, the axis of one fifth hinging shaft and the axis of the other fifth hinging shaft are intersected at an intersection point; the intersection point in one support mechanism 2 and the intersection point in the other support mechanism 2 are located on both sides of the linkage mechanism 1. Here, it is pointed out that: the fifth hinge shaft is positioned so that the two diagonal bracing mechanisms 24 can form a triangular pyramid shape in cooperation with the upright rod 21, thereby further enhancing the supporting strength.

According to a further embodiment, the connecting member 123 comprises a first portion 1231 and a second portion 1232 connected by a thread, the first portion 1231 and the second portion 1232 together forming a cavity therebetween. A circular through hole is opened at the first portion 1231, and the second portion 1232 and the diagonal brace 241 are hinged at a first point through a ninth hinge shaft.

It should be noted that the second portion 1232 is not limited to be hinged to the diagonal brace 241, and can be hinged to the bottom frame rod 242.

In this embodiment, the connecting member 123 is formed as the first and

second portions

1231 and 1232 which are detachably attached, and when the first and

second portions

1231 and 1232 are separated by unscrewing, the leg rest mechanism can be detached from the diagonal brace 241 and separately housed, thereby enabling switching between the two forms of the folding stand with and without the leg rest mechanism.

The utility model also provides a take folding chair of bracket:
