Description

Micro-elastic cushion disc for connecting seat bottom plate and supporting column

Technical Field

The utility model relates to a spare and accessory part of a combined seat, in particular to a micro-elastic connecting part pad disc for connecting a seat cushion and a support frame of the combined seat.

Background

The seats in the places such as dining halls, fast restaurants and the like are simple combined seats with one supporting column below one seat plate, and the seat plate of the combined seat and a connecting part cushion disc for connecting the supporting frame are all in steel structures and steel connecting modes, so that people feel hard and uncomfortable on the seat.

Disclosure of Invention

The utility model aims to provide a connecting component for connecting a seat board and a supporting frame of a combined seat, which is a pad disc with a micro-elastic structure and a micro-elastic connecting mode.

The utility model has the structure that:

firstly, only establish little elastic construction on the saucer body: the elastic limit is limited by the structure of the elliptical connecting hole 4 and the positioning notch 5, namely the cushion disk for limiting the elastic connection displacement limit of the cushion disk and the seat plate: little elastic cushion dish that seat bottom plate and support column are connected, including the disk body of middle protruding cambered surface 1 and marginal narrow limit plane 2, be slope 6 between middle protruding cambered surface 1 and marginal narrow limit plane 2, be equipped with many shallow protruding 3, its characterized in that on domatic 6 between middle protruding cambered surface 1 to marginal narrow limit plane 2: the edge narrow side plane 2 is provided with a plurality of elliptical connecting holes 4, and the outer edge of the edge narrow side plane 2 is provided with a plurality of positioning notches 5.

The long axis of the elliptic connecting hole 4 is the same as the direction of the radius line from the center of the pad disc to the periphery; the seat plate at the position of each positioning notch 5 is provided with a positioning stud 12, and each positioning notch 5 has a slight clearance with the positioning stud 12 clamped therein. When a person sits on the seat board downwards, the slope 6 deforms, the gradient of the slope 6 is reduced, the height difference between the middle convex arc surface 1 and the edge narrow side plane 2 is reduced, the edge of the pad expands outwards, and a gap is reserved between each positioning notch 5 and the positioning short column 12 clamped in the positioning notch 5 because of the clearance between the oval connecting hole 4 and the middle connecting stud; therefore, the cushion disc can generate slight elastic deformation, and people can sit on the cushion disc with certain elasticity and comfort. In a small elastic deformation range, the pad plate is easy to restore to the original shape, and provides elasticity for the next sitting of a person. So that the two structures of the elliptical connecting hole 4 and the positioning notch 5 are connected with the seat board of the seat with a micro gap or the like, thereby realizing restorable elastic deformation of the cushion disc.

The shallow protrusions 3 serve to improve the slope 6 into a structure with more stress elasticity.

The second type adds the return elastic component: set up the part that can increase the resilience force on the saucer body, it is more powerful effective to make the saucer return former shape, the elastic life of extension saucer, the structure is, on the basis of a structure, be equipped with two on domatic 6 of protruding cambered surface 1 in the middle of and marginal narrow limit plane 2 to perforation 7, these two are located two relative sides of protruding cambered surface 1 in the middle of to perforation 7 respectively, these two are to penetrating a both ends screwed center pillar 8 between perforation 7, the end that stretches out the disk body in these center pillar 8 both ends is equipped with nut 9, the cover has external spring 10 on the center pillar 8 between disk body and the nut 9.

Preferably, the center post 8 between two pairs of through holes 7 in the disc body is sleeved with an inner spring 11, and two ends of the inner spring 11 are respectively welded and fixed with the two pairs of through holes 7.

When the people sits down on the seat board, the slope 6 deforms, the slope of the slope 6 becomes smaller, the distance between the two opposite through holes 7 on the slope 6 increases, the outer spring 10 is compressed, and the inner spring 11 is elongated. After the people do not sit on this bedplate, the resilience force of reseing of outer spring 10 and inner spring 11 promotes the structural elasticity of saucer and resumes the shape, enables the utility model discloses a saucer has little elastic construction and can keep longer time, and the little elasticity durability that the saucer has increases promptly.

The utility model has the advantages that: the utility model discloses a rim plate not only makes the combination formula seat have little elasticity, and has its little elasticity durable, has the combination formula seat that has this kind of rim plate, and the people has little elasticity and is very comfortable on the seat with oval connecting hole and location notch structure limited rim plate elasticity limit to and have outer spring and interior spring reinforcing rim plate little elasticity durability.
