Abstract
The utility model discloses an improved swivel chair headrest structure which comprises a headrest body and a headrest bracket, wherein a bending part is arranged at the upper end of the headrest bracket, and is connected with the back of the headrest body; a support leg is arranged at the back of the headrest body; the headrest body and the headrest bracket are hinged through a pin; the pin is a sexangular screw stud which is preferably selected, and the tail end of the pin is screwed by a knob; during adjustment, the bolt connection can be loose or tight, and when the head of a user is leaned against the headrest, the user selectively enables the headrest to rotate freely or to be fixed in the position with a comfortable angle, so that the comfortable sensation is stronger when the headrest is in use.
Description
Technical field
The utility model relates to a kind of swivel chair head rest and a syndeton of the back of the body.
Background technology
At present, the top of the present back of the body of a lot of office revolving chairs can install a head rest additional, rely on and use for clerical workforce's head, commonly used directly is fixed as one head rest and the seat back of the body, also have through architecture advances, increased the oscilaltion function of head rest, as authorized the Chinese utility model of disclosed CN202234106 on May 23rd, 2012, in this mechanism, the head rest support inserts in the chute of seat behind section, establish retaining mechanism in chute, but so just oscilaltion of head rest, and can be fixed on a certain position by locking device, thereby meet the people of different height bodies, but this head rest can not rotate adjusting, sometimes the clerical workforce the unlucky head of seat can be to layback backward, if now head rest can be stressed and with head rotation or adjust to a comfortable angle, can increase clerical workforce's head comfort.
The utility model content
The utility model technical issues that need to address are, a kind of improvement structure of swivel chair head rest is provided, and the head rest that has solved swivel chair can not rotate to be regulated and causes the not good problem of comfort.
The technical solution of the utility model is: a kind of improvement structure of swivel chair head rest, comprise head rest body and head rest support, head rest support upper end is provided with bending part, this bending part connector is by the back of body, it is characterized in that: there is a leg at described head rest body back, leg has a lateral direction penetrating pin-and-hole, and the head of head rest support bending is provided with the perforation of lateral direction penetrating, and pin is hinged by head rest support and leg through perforation and pin-and-hole.
Preferably, described pin is hexagonal double-ended bolt, and tail end is tightened with knob, and bolt connects stretch, is convenient to regulate.
Preferably, there is through slot longitudinally at described head rest support and leg link position place, and leg is located in through slot, and convenient the installation connects.
Preferably, there is the regular hexagon cavity that holds the hex screw head described head rest support side, and hexagonal cavities can allow the head of hexagonal double-ended bolt embed in the head rest support, and hexagonal double-ended bolt rotates while adopting hexagon can prevent the knob rotation.
Preferably, be added with the damping friction plate between the installation contact-making surface of described head rest support and leg, when the head rest body rotates, the damping friction plate can provide certain frictional force, improve the comfort while rotating, and, when user's head leaves the head rest body, frictional force can prevent that the head rest ontological idea of freedom from falling.
Preferably, described knob inside center is marked with nut because single nut while regulating hand be not easy operation, so nut can be injection molded into to one when knob is manufactured moulding.
Preferably, described knob outer surface is surrounded with anti-slip tank, and anti-slip tank can allow the user increase frictional force when regulating.
After adopting technique scheme, the utlity model has following advantage: the head rest body is articulated and connected by leg and head rest support, articulated manner is preferentially with bolts, and regulate with knob, when knob unclamps, head rest is free to rotate, during knob locking, head rest can need to be adjusted to a comfortable angle according to the user, when so user's head leans against on head rest, can select to allow it freely rotate or be fixed on an angle of oneself feeling comfortable, and while using like this, comfort is stronger.
The accompanying drawing explanation
Accompanying drawing 1 is overall schematic of the present utility model;
Accompanying drawing 2 is schematic side view of the present utility model;
Accompanying drawing 3 is schematic top plan view of the present utility model;
The structural representation that accompanying drawing 4 is knob.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
As shown in Figures 1 to 4, the utility model mainly comprises head rest body 2, there is a leg 21 at the back of head rest body 2, leg 21 laterally is provided with the pin-and-hole 22 of perforation, corresponding with pin-and-hole 22, also be provided with the perforation 11 of lateral direction penetrating on head rest support 1 bending part, pin can be hinged to realize head rest support 1 and leg 21 through perforation 11 and pin-and-hole 22 successively, in this example, pin is hexagonal double-ended bolt 5, hexagonal double-ended bolt 5 ends are rotary with knob 6, the face axially contacted with hexagonal double-ended bolt 5 heads in perforation 12 is provided with hexagon cylindrical cavity 12, so that the head of hexagonal double-ended bolt 5 can embed in cylindrical cavity 12, be chosen as hexagonal cross-section, in the time of can preventing knob 6 adjusting, hexagonal double-ended bolt 5 rotates, knob 6 inside are injected with nut 61, nut 61 coordinates with hexagonal double-ended bolt 5, skid when preventing adjusting knob 6, all be provided with anti-slip tank 62 around knob 6 outer surfaces, during adjusting, loosening knob 6, head rest body 2 just can freely rotate, can follow user's head to any angle, when tightening knob 6, the user can be fixed on the angle of oneself thinking comfortable to head rest body 2, increase comfort, and in this example, as shown in Figure 3, when knob 6 unclamps, comfort while rotating in order to increase the head rest body, also prevent that head rest can be because the problem of whereabouts be rotated in the deadweight meeting voluntarily when user's head leaves head rest body 2, so accompany frictional damping sheet 7 between leg 21 and head rest support 1 contact-making surface, certain frictional force is provided when rotating between the two.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims, its concrete structure allows to change, as pin adopts the form of self-tapping screw hinged, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
