Example one

The embodiment of the utility model provides a back structure mainly is applied to the scene that the user need support when keeping the position of sitting, also can be applied to the scene that the user needs to support alone, and it has certain fine setting effect, can improve user's comfort level.

As shown in fig. 1, 3 and 4, the backrest structure includes a back frame 1 for supporting a back, and support portions 11 respectively extending along a pressing direction of both sides of the back frame 1. Wherein the pressing direction refers to the pressing direction of the back frame 1 when the user backs on the back frame 1, and the direction is perpendicular to the surface of the back frame 1.

The support parts 11 on both sides are provided with deformation holes 12.

Specifically, when the user keeps the position of sitting, support user's back through back frame 1, deformation hole 12 that sets up through supporting part 11 makes back frame 11 can slightly adjust certain angle backward when the atress, makes the user feel comfortable, satisfies the pursuit of user to the comfort level, has improved product competitiveness. It is to be added that when the user leans the back against the back frame 1, the back frame 1 receives the force applied from the back, the force is transmitted to the supporting portion 11, the supporting portion 11 is provided with the shape changing hole 12, the cross section area of the periphery of the supporting portion provided with the shape changing hole 12 is small, the rigidity of the supporting portion is small, and the supporting portion can be slightly deformed under the action of the force, so that the supporting portion can be displaced along the direction of leaning against the back of the user, and the effect of better fitting the back of the user is achieved.

Further, the bottom of each of the two support portions 11 is provided with a back link 2 for fixedly connecting the back frame 1 to the seat, and the back link 2 is fixedly connected to the support portions 11. Through the arrangement of the back connecting piece 2, the back frame 11 is supported, and meanwhile, the back frame 11 is convenient to be connected to a seat, wherein the application range of the backrest structure is widened due to the structures such as a cushion, a mattress and the like provided by furniture such as a seat of a seat finger.

Further, as shown in fig. 1 and 2, a back connection block 21 is convexly provided on a side of the back connection member 2 facing the support portion 11; the supporting portion 11 is provided with a receiving groove corresponding to the back connecting block 21.

The back connecting block 21 is detachably sleeved in the accommodating groove and is fixedly connected with the supporting part 11 through a fastener. Specifically, through establishing supporting part 11 cover on back even connecting block 21, the location is effectual, plays good fixed action, connects supporting part 11 and back even connecting block 21 through the fastener simultaneously, non-deformable, stable in structure.

In a specific implementation mode, the back frame 1 is provided with a plurality of mesh holes arranged at intervals, so that the backrest structure is more integrated and more stable.

In another specific implementation manner, the back frame 1 is provided with a mesh surface groove, a mesh surface layer is arranged in the mesh surface groove, and the mesh surface layer is a flexible mesh cloth with meshes; the back frame 1 is less in material consumption, and the effect of flexible support is achieved through the net surface layer, so that the comfort level of a user is higher.

Further, as shown in fig. 1, a support 13 is disposed in the deformation hole 12 along the compression direction; both ends of the supporting member 13 are integrally formed with the hole walls of both sides of the deformation hole 12, respectively. The situation that the supporting part 11 is broken due to overlarge local deformation of the deformation hole 12 can be avoided through the arrangement of the supporting part 13, and the stability of the backrest structure is improved.

Further, the back frame is the nylon framework, and it has good pliability, satisfies the demand of user to the comfort level of back structure.

Further, the deformed hole 12 is an oblong deformed hole. The supporting part 11 is made of an oblong hole-changing arrangement
