The present utility model will be described in detail with reference to fig. 1 to 3.

Examples

The utility model provides a folding seat mechanism of upset of flexible stand, includes at least one seat subassembly, the seat subassembly includes base 1, articulated on the base 1 have first support piece 2 and second support piece 3, the one end that base 1 was kept away from to first support piece 2 and second support piece 3 articulates there is seat 4, be provided with the locking mechanical system that is used for keeping first support piece 2 and second support piece 3 in vertical state on the base 1.

The lengths of the first supporting piece 2 and the second supporting piece 3 are the same, when the first supporting piece 2 and the second supporting piece 3 are in a vertical state, the locking mechanism enables the first supporting piece 2 and the second supporting piece 3 to keep in the vertical state, and at the moment, the stool 4 is used for sitting by people; when folding is needed, the locking mechanism is unlocked, the first supporting piece 2 and the second supporting piece 3 are turned to one side, the supporting leg parts of the seat are folded to reduce the height, and the number of steps of the stand can be increased under the condition that the whole height of the stand is the same, so that the number of seats is increased, and more people can be accommodated for use.

The locking mechanism comprises a self-locking piece 5 hinged on the base 1, a clamping groove 9 is formed in the self-locking piece 5, a clamping rod 8 is fixedly connected to the first supporting piece 2, and the self-locking piece 5 is connected with a first elastic piece 6 used for keeping the clamping groove 9 and the clamping rod 8 in clamping.

When the first support piece 2 and the second support piece 3 are unfolded from the folded state, the clamping rod 8 on the first support piece 2 rotates into the clamping groove 9, so that the swing of the first support piece 2 is limited, the vertical state of the first support piece 2 is kept, the clamping rod 8 is kept clamped into the clamping groove 9 by the first elastic piece 6, and the first support piece 2 is prevented from swinging and folding due to the fact that the clamping rod 8 is separated from the clamping groove 9. When the locking is needed to be released, the self-locking piece 5 is controlled to rotate, so that the clamping groove 9 is separated from the clamping rod 8. The first elastic member 6 may be provided as a torsion spring, and is mounted at the hinge of the self-locking member 5, with one end of the torsion spring being connected to the self-locking member 5 and the other end being connected to the base 1.

In order to prevent the seat from being folded backwards, the base 1 is provided with the stop piece 7, and the stop piece 7 limits the first support piece 2 to move in the direction opposite to the folding direction, so that the use safety of the seat is ensured.

The end face of the self-locking element 5, which is close to the second support element 3, is provided with a guiding bevel 10.

In the folding process of the seat, due to the action of gravity, downward impact force is generated, and the second elastic piece 11 on the first supporting piece 2 buffers the impact force of the seat, so that the seat is prevented from being damaged due to impact. The second elastic member 11 is also a torsion spring, which is disposed at the hinge of the first supporting member 2, and has one end connected to the first supporting member 2 and the other end connected to the base 1.

The seat assembly is provided with at least two, the self-locking piece 5 in all seat assemblies is connected with the same first connecting rod 12, and all the stools 4 are connected with the same second connecting rod 14. By connecting the first connecting rod 12 and the second connecting rod 14, all the seat assemblies on the same straight line are unfolded or folded simultaneously, and the work intensity of unfolding or folding the seat assemblies is reduced. Wherein the first connecting rod 12 controls all the self-locking members 5 to rotate simultaneously, so that all the connected seat assemblies are locked and unlocked simultaneously.

The second support 3 is provided with a recess 13 for receiving the second connecting rod 14 when the second support 3 is folded. After the seat is folded, the second connecting rod 14 is clamped into the groove 13, so that the height of the folded seat is further reduced.

The first connecting rod 12 is arranged into a square rod, so that tools such as a wrench and the like can be conveniently used for rotating the first connecting rod 12, and the self-locking piece 5 is driven to rotate to unlock the first supporting piece 2.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
