[utility model content]

The utility model provides a kind of chair back display unit, can not adjust the technical matters that user's viewing angle is restricted to solve above-mentioned chair back display unit read-out angle.

In order to solve the problems of the technologies described above, the utility model provides a kind of chair back display unit, comprises the base and the read-out that are installed on the chair back back seat, and described read-out is connected with described base by the torsional moment hinge device.

Described torsional moment hinge device is Damping rotation shaft.

Described torsional moment hinge device is arranged on position, top edge, described centre.

Described base midway location is groove structure, and described groove is slightly larger than the size of described read-out, is used for placing described read-out.

Described torsional moment hinge device is two, lays respectively at described read-out edge and described base connection location.

Be provided with the bayonet unit that is complementary with described read-out at relative edge, described floor installation torsional moment hinge position, be used for described read-out is fixed on described base.

Described torsional moment hinge device allows the approximately rotation of 200 degree of described read-out.

Because it is device that the chair back that the utility model provides shows, read-out is connected with base by the torsional moment hinge device.Read-out just can be rotated by the torsional moment hinge device like this, and can the foundation actual needs of watching of user are adjusted the angle of read-out, make the user reach optimum experience.

In addition, because the torsional moment hinge device is Damping rotation shaft, Damping rotation shaft has good reliability, and service life is longer.

In addition, because the base midway location is groove structure, groove is slightly larger than the size of read-out, be used for placing read-out, when read-out is closed, read-out will with the base one, structure is very attractive in appearance.

In addition, because the torsional moment hinge device is two, lay respectively at read-out edge and base connection location, two torsional moment hinge devices are so that read-out is connected very reliable with base.

In addition; because relative edge, floor installation torsional moment hinge position is provided with the bayonet unit that is complementary with read-out; be used for read-out is fixed on described base; when the user does not need to use read-out; can be with read-out rotating closed and by bayonet apparatus read-out is fixed on the base; so that whole read out instrument is an integral body, and can protect well read-out.

decorative ends

41 and 42 at the two ends of base 1; Be provided with the bayonet unit 5 that is complementary with read-out 2 at base 1 mounting torque hinge means 31, relative edge, 32 positions; At close bayonet unit 5 places of the groove floor of base 1, lay respectively at two jiaos of base 1 grooves and be provided with two

rubber pads

11,12.

Because the chair back display unit that this implementation column provides, read-out 2 is connected with base 1 by torsional

moment hinge device

31,32, read-out 2 just can be rotated by torsional

moment hinge device

31,32 like this, and can the foundation actual needs of watching of user are adjusted the angle of read-out; In addition, because torsional

moment hinge device

31,32 is Damping rotation shaft, Damping rotation shaft has good reliability, and, because torsional

moment hinge device

31,32 is two, lay respectively at read-out 2 edges and base 1 connection location, two torsional

moment hinge devices

31,32 are so that the connection that read-out 2 is connected with base is very reliable, and service life is longer; In addition, because base 1 midway location is groove structure, groove is slightly larger than the size of read-out 2, be used for placing read-out 2, when read-out 2 is closed, read-out 2 will with base 1 one, structure is very attractive in appearance.
