Description

Technical Field

[0001] The utility model relates to the technical field of energy storage conversion, in particular to a structural component for stepped chairs. Background Art

[0002] Step chairs are generally used in occasions such as stepped classrooms. Since the chairs are foldable, they can be folded by rotating the reset parts when users do not need to use them, providing users with a certain space to walk. When users need to sit down, the chairs are pressed down by the users sitting down, so that the chairs remain in the unfolded state. The use of this product saves a certain amount of space while increasing the number of people that can be accommodated in the stepped classroom.

[0003] However, the products currently on the market are not tightly connected between the load-bearing rod and the fixed rod. When the force on the load-bearing rod increases, abnormal noises are likely to occur, which reduces the user experience.

[0004] Therefore, how to improve the connection tightness between the load-bearing rod and the fixed rod and reduce the occurrence of abnormal noise is a problem that technicians currently need to solve. Utility Model Content

Since the two ends of the load-bearing rod are adapted to the clamping blocks and the two ends of the load-bearing rod are clamped onto the clamping blocks, when the force on the load-bearing rod increases, the connection between the load-bearing rod and the fixed rod is tight, thereby reducing the occurrence of abnormal noise.

[0006] The utility model provides a structural member for a stepped row of chairs, comprising:

[0007] foldable chairs, load-bearing and fixed poles;

[0008] The foldable chair is located on the load-bearing rod, and the foldable chair is connected to the load-bearing rod;

[0010] The connecting piece is provided with a clamping block, and the clamping block is clamped to the connecting piece;

[0011] Both ends of the load-bearing rod are respectively welded to the corresponding clamping blocks.

[0012] Furthermore, the load-bearing rod is connected to the fixing rod based on the clamping block.

[0013] Furthermore, the foldable chair includes a fixing member, a rotation reset member and a chair body;

[0014] One end of the fixing member is connected to the rotation reset member;

[0015] The rotation restoration member is connected to the chair body.

[0016] Furthermore, the other end of the fixing member is connected to the load-bearing rod by bolts.

[0017] Furthermore, the chair body is rotatably connected to the load-bearing rod based on the rotational reset member.

[0018] The utility model provides a structural member for a stepped row of chairs, which is welded to one side of a fixed rod through a connecting member, a clamping block is clamped onto the connecting member, and two ends of a load-bearing rod are respectively welded to corresponding clamping blocks, so that the two ends of the load-bearing rod are connected to the fixed rod. Since the two ends of the load-bearing rod are adapted to the clamping blocks and the two ends of the load-bearing rod are clamped onto the clamping blocks, when the force applied to the load-bearing rod increases, the connection between the load-bearing rod and the fixed rod is tightly connected, thereby reducing the occurrence of abnormal noise.
