Abstract

The invention discloses an improved structure of a head rest of a swivel chair. The improved structure comprises a head rest body and a head rest bracket, wherein the upper end of the head rest bracket is provided with a bent part; the bent part is connected with a back part of the head rest body; the back part of the head rest body is provided with a supporting leg; the head rest body is hinged to the head rest bracket through a pin; the pin is preferably a hexagonal bolt; the tail end of the pin is screwed up by using a knob and can be loosened and tightened during adjustment; when a user leans the head on the head rest, the head rest can freely rotate or be fixed at an angle the user feels comfortable optionally, so that the comfortable sensation is stronger when the improved structure is in use.

Description

A kind of improvement structure of swivel chair head rest

Technical field

The present invention 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 usefulness 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 authorizing the Chinese invention of disclosed CN202234106 on May 23rd, 2012, the head rest support inserts in the chute of seat behind portion in this mechanism, in chute, establish retaining mechanism, but so just oscilaltion of head rest, and can be fixed on a certain position by locking device, thus satisfy 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 this moment, head rest can be stressed and with head rotation or adjust to a comfortable angle, can increase clerical workforce's head comfort.

Summary of the invention

The technical issues that need to address of the present invention 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 cause the not good problem of comfort.

Technical scheme of the present invention 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, pin pass the perforation and pin-and-hole head rest support and leg is hinged.

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 the 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 when 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, the damping friction plate can provide certain frictional force when the head rest body rotates, improve the comfort when rotating, and when user's head left 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 when regulating hand be not easy operation, so when knob is made moulding, nut can be injection molded into one.

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 present invention has following advantage: the head rest body is articulated and connected by leg and head rest support, articulated manner preferentially adopts bolt to connect, and regulate with knob, head rest was free to rotate when knob unclamped, head rest can be adjusted to a comfortable angle according to user's needs during knob locking, can select to allow it freely rotate or be fixed on an angle of oneself feeling comfortable when so user's head leans against on the head rest, and comfort is stronger when using like this.

Description of drawings

Accompanying drawing 1 is overall schematic of the present invention;

Accompanying drawing 2 is schematic side view of the present invention;

Accompanying drawing 3 is schematic top plan view of the present invention;

Accompanying drawing 4 is the structural representation of knob.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:

As shown in Figures 1 to 4, the present invention 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 pass perforation 11 successively and pin-and-hole 22 is hinged to realize head rest support 1 and leg 21, pin is hexagonal double-ended bolt 5 in this example, hexagonal double-ended bolt 5 ends are rotary with knob 6, the face that axially contacts 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 the cylindrical cavity 12, be chosen as hexagonal cross-section, hexagonal double-ended bolt 5 rotates in the time of can preventing knob 6 adjustings, knob 6 inside are injected with nut 61, nut 61 cooperates 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, increases comfort, and in this example, as shown in Figure 3, when knob 6 unclamped, the comfort when rotating in order to increase the head rest body prevented that also 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 between leg 21 and head rest support 1 contact-making surface, accompany frictional damping sheet 7, certain frictional force be provided when rotating between the two.

Below only be described with regard to the preferable example of the present invention, but can not be interpreted as it is limitations on claims, its concrete structure allows to change, adopt the form of self-tapping screw hinged as pin, those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
