Description of the drawings
Fig. 1 is the structural schematic diagram of backrest elastics wing device；
Fig. 2 is the front view of spring steel plate；
Fig. 3 is the left view of spring steel plate.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment 1：
A kind of backrest elastics wing device is provided with as shown in Figure 1, including the chair back 5 and tripod 12 in the chair back 5
Backer board 11, the rear portion of backer board 11 are additionally provided with the spring steel plate 1 for making the chair back swing, and the lower section of backer board 11 is provided with limit
Part 3, the locating part 3 are fixedly mounted on by screw 4 on spring steel plate 1.In the present embodiment, the lower section of backer board 11 is provided with short
Axis 11.1, locating part 3 are provided with circular hole 3.1, and short axle 11.1 moves in circular hole 3.1.When leaning on the chair back 5, in the chair back 5
Backer board 11 is under pressure, and makes to move in circular hole 3.1 of the short axle 11.1 in backer board 11 in limiting plate 3.When pressure is larger
When, the resistance of the circular hole 3.1 in by limiting plate 3 of short axle 11.1, to make backer board 11 realize limit.Upper spring steel plate 1 includes the
One elastic plate 1.1, the second elastic plate 1.2 and the bending for connecting the first elastic plate 1.1 and the second elastic plate 1.2
Plate 1.3, and the first elastic plate 1.1, the second elastic plate 1.2 connect and compose Z-type structure with bending plate 1.3.In spring steel plate 1
The first elastic plate 1.1 be fixed on backer board 11 by screw 2.A holder 6 is provided on tripod 12, it is parallel with holder 6
Endface be provided with a pressing plate 7, the second elastic plate 1.2 in spring steel plate 1 be mounted between pressing plate 7 and holder 6, and
Itself and pressing plate 7 and holder 6 are fixed with nut 8 by bolt 9, flat shim 10.
It should be noted that backrest elastics wing device described in the utility model, structure design is simple, passes through
The spring steel plate of a compression moulding, may be implemented the elastics wing of the chair back after installation quenches onto the backing plate.With existing elasticity
Structure in swing seat is compared, and the spring steel plate of the utility model can deform caused by avoid being heat-treated after processing,
The intensity and toughness that spring steel plate can be further increased, to improve the performance and used life of product；And this practicality is new
Type relies solely on screw, bolt, flat shim, nut just part combinations such as spring steel plate, locating part, holder, pressing plate, backer boards
Together, quick and easy for installation；Secondly, which is the steel plate of Z-type structure, and the bending plate in spring steel plate may be implemented
The swing of the chair back, and swing amplitude range in the deformation range of bending plate, can be excessive to avoid chair back amplitude of fluctuation and lead
Cause the chair back that can not reply.
Locating part 3 is arranged in the lower section of backer board 11, which can further limit the amplitude of chair back swing, avoid
5 amplitude of fluctuation of the chair back is excessive and causes the chair back 5 that can not reply, and shortens the service life of backrest elastic device.
Second elastic plate 1.2 is arranged between pressing plate 7 and holder 6 in spring steel plate 1, and passes through nut 8, bolt 9, flat
Gasket 10 is fixed, and this design can improve the fastening force of spring steel plate 1 and tripod 12, avoids spring steel plate 1 long-term
It loosens and is detached from tripod 12 in swing process, can not achieve oscillating function；Can also reduce simultaneously spring steel plate 1 and bolt 9 it
Between the degree of wear, prolong the service life.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
