Description
Technical Field
The utility model relates to an angle-adjustable chair headrest, in particular to a connecting structure between a finger headrest frame and a supporting component thereof.
Background
The headrest frame and support connection structure that uses at present roughly has two kinds:
1. in a fixed type, the headrest support and the headrest frame are integrated. This approach has the following disadvantages: no regulating function: the headrest support and the headrest frame are made as one fitting, and since there is no adjustment function, the angle of the headrest cannot be adjusted according to the needs of the individual's body when the seat is used, thereby reducing the comfort.
2. A movable joint is arranged between the headrest support and the headrest frame: the mode has the advantages of complex structure, more accessories, fussy assembly process and high production cost.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is directed to the defects in the prior art, and the main object of the present invention is to provide a headrest with simple structure, low cost and angle adjustment function, so as to meet the needs of people.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides an angle-adjustable chair headrest, includes headrest frame, headrest support, headrest locating piece, screw and fabric, the locating piece is established two altogether, two locating pieces link together headrest frame and headrest support through the screw.
Preferably, the bottom of the positioning block is provided with a semicircular groove, and the middle of the positioning block is provided with a small hole for locking a screw.
Preferably, one side (back) of the headrest frame connected with the headrest support is provided with an arc-shaped groove, one side (front) of the headrest frame 2 facing the fabric 5 is provided with two semi-cylindrical salient points, and the distance and the radian of the semi-cylindrical salient points are matched with the grooves at the bottom of the positioning blocks.
Preferably, one end of the headrest support, which is connected with the headrest frame, is provided with an arc-shaped end, a square limiting tenon is arranged in the middle of the end, and a small hole for locking a screw is formed in the middle of the limiting tenon.
Preferably, the headrest frame is rotatable 16-48 °.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 4, an embodiment of the present invention: a chair headrest with an adjustable angle,
comprises a headrest support 1, a headrest frame 2, a headrest positioning block 3, a screw 4 and a fabric 5.
This embodiment the locating piece 3 establishes two altogether, and its bottom is provided with semicircle type recess, and the centre is provided with the aperture that is used for the screw lock to go into. The positioning block 3 connects the headrest frame 2 and the headrest support 1 together through a screw 4. Two semi-cylindrical salient points are respectively arranged on the frames on two sides of one surface (front surface) of the headrest frame 2 facing the fabric 5, and the space and the radian size of the semi-cylindrical salient points are matched with those of the grooves at the bottom of the positioning block 3. When headrest frame 2 rotates, the mutual interlock effect of semicircle type recess on the locating piece 3 and the semicircle column shape epirelief point on the headrest frame 2 when the dynamics reaches a definite value, through the deformation of material itself, headrest frame 2 breaks through and can rotate to next screens behind the resistance to realize the regulation and the location of different angles.
This embodiment one side (the back) that headrest frame 2 and headrest support 1 are connected is provided with two circular-arc grooves, the one end that headrest support 1 and headrest frame 2 are connected sets up two circular-arc ends, and the recess radian phase-match at its radian and the back of headrest frame 2, and when headrest frame 2 rotated, circular-arc groove on the headrest frame 2 and the circular-arc end interlock on the headrest support 1 provided the space for relative motion. A square limiting tenon is arranged in the middle of the arc-shaped end of the headrest support 1, and a small hole for locking a screw is formed in the middle of the limiting tenon. The square positioning tenon limits the rotation angle of the headrest frame within a certain range so as to meet the requirements of people on comfort and supporting force when the headrest is used. The headrest frame can rotate by 0-60 degrees, and the headrest of the embodiment can rotate by 16-48 degrees.
The fabric 5 on the headrest frame 2 may be made of different materials, and in this embodiment, a mesh fabric is used.
