Detailed Description

Example 1:

referring to fig. 1 to 7, a chair with a lumbar pillow includes a main body including a backrest 1; the structures of other positions on the chair are not described in detail, and only the structure on the backrest 1 is described.

Be equipped with waist pillow 2 and adjustment mechanism 3 on the back 1, waist pillow 2 includes connecting piece 4 and a plurality of blade 5, and the quantity of connecting piece 4 here is two, and two connecting pieces 4 are the symmetry setting, and the one end of connecting piece 4 is fixed with the top of back 1, and the concrete fixed prevention of here can be for the bolt-up, perhaps the round pin axle is fixed etc.. The other end of the connecting member 4 is connected and fixed by a connecting portion 41, where the connecting portion 41 may be a cylindrical shaft connected and fixed with the connecting member 4. The connecting portion 41 is provided with two fixing protrusions 42 adapted to the link member 6. The connecting piece 4 is also provided with a plurality of swelling parts 43 corresponding to the vanes 5, the swelling parts 43 are internally provided with grooves 431, and one side surface of the swelling parts 43 facing the outer side of the backrest 1 is closed.

Blade 5's quantity can be equipped according to actual demand, and blade 5 is the array and fixes on connecting piece 4, specifically is equipped with fixed column 51 and fixed slot 52 on the blade 5, and fixed column 51 specifically is located fixed slot 52, and fixed column 51 stretches into to recess 431 internal fixation, fixed slot 52's width and connecting piece 4 adaptation for connecting piece 4 forms dual fixed with blade 5. It should be noted here that, since the number of the connecting pieces 4 is two, the number of the fixing slots 52 and the fixing posts 51 on the blade 5 is two. The specific structure of the blade 5 is convex, which is more fit for the waist of human body.

The adjusting mechanism 3 comprises a screw 7, a linkage member 6 and a transmission member 8, wherein a spiral convex rib 71 is arranged on the screw 7, a blocking part 72 is arranged in the middle of the screw 7, and the blocking part 72 is used for separating and blocking. The screw 7 is further provided with rotating portions 73 at both ends thereof, and a user rotates the screw 7 by rotating the rotating portions 73. Here, the number of the linkage members 6 and the transmission members 8 is two, and the two linkage members and the transmission members are symmetrically arranged relative to the blocking portion 72, so that only one of the structures is described here, and the other structure is the same, which is not described in detail.

The transmission member 8 is sleeved on the screw rod 7, and a spiral groove 81 matched with the spiral convex rib 71 is arranged in the transmission member 8, so that the transmission member 8 can better move on the screw rod 7. Two symmetrical bulges 82 are arranged on the transmission piece 8, and the bulges 82 are used for being connected and fixed with the linkage piece 6.

The link member 6 is formed in an X-shaped structure, that is, fixing grooves 61 are formed at both ends of the link member 6, the fixing groove 61 at one end of the link member 6 allows the connecting portion 41 to be located in the fixing groove 61, and the fixing groove 61 at the other end of the link member 6 allows the screw 7 to be located in the fixing groove 61. The two side walls of the fixing groove 61 are provided with notches 62, and the notches 62 are matched with the protrusions 82 and the fixing protrusions 42, that is, when the linkage member 6 is matched with the connecting portion 41, the notches 62 are also matched and fixed with the fixing protrusions 42. Similarly, when the linkage member 6 is matched with the transmission member 8 on the screw 7, the notch 62 is also matched and fixed with the protrusion 82.

Waist pillow 2 one end is fixed with the top of back 1, and the other end of waist pillow 2 is through rotating screw rod 7 for driving medium 8 slides on screw rod 7, and driving medium 8 drives the linkage of linkage 6, drives connecting piece 4 rebound, because the other end of connecting piece 4 is fixed with back 1, the power that produces this moment makes connecting piece 4 take place deformation bending, thereby makes blade 5 more with the waist laminating of human body, plays the effect of supporting the waist. The waist pillow 2 can adapt to crowds of different body types by the aid of the structure, and the deformation angles of the blades 5 are different by the aid of the adjusting screw 7, so that the waist pillow can adapt to requirements of different crowds.
