Description
Technical field
The utility model relates to a kind of head rest adjusting device, relates in particular to a kind of chair head rest adjusting device.
Background technology
In daily life, office and amusement, chair has become a kind of indispensable staple, in order to strengthen comfort, has all added headrest on most of chair.Yet; The current chairs headrest all is to adopt the design standard that is suitable for popular use to produce in batches on the market, and its headrest is fixedly connected on the chair unadjustable, finds so in actual use; When in the face of different users or different user demand; Existing headrest is because unadjustable position, can not be always support user's head well, thereby reduced comfort.Therefore, be necessary for the chair head rest adjusting device that people provide a kind of headrest positions of flexible as required and can manufacture.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of chair head rest adjusting device, and it is flexible headrest positions and can manufacture as required, strengthens comfort.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of chair head rest adjusting device; Comprise headrest, support member, first damping block, second damping block and control piece; The back side of said headrest is provided with adjusting rod, and the upper end of support member is provided with first baffle plate respect to one another and second baffle, has a through hole on first baffle plate; Have a screw on the second baffle, have cavity between two baffle plates; First damping block, second damping block are installed in the cavity relative to one another; Wherein, The outer face of first damping block is provided with the joint pin of an insertion through hole, and the outer face of second damping block is provided with the recess superimposed with screw, and the inner face of two damping blocks is respectively equipped with the notch of an opposed openings; Control piece has a control screw rod, and this control screw rod is threaded with screw on the second baffle and stretches into recess second damping block is withstood, and adjusting rod passes the notch of two damping blocks, by the notch of two damping blocks it is fixedly clamped.
As a kind of preferred version, said first damping block, second damping block are cylindrical.
As a kind of preferred version, said control piece also comprises a circular bottom plate, and the control screw rod is fixed on this base plate.
A kind of chair head rest adjusting device that the utility model is set forth, its beneficial effect is: the control screw rod of this product utilization control piece withstands second damping block and realizes the spacing of adjusting rod of resting the head on, because the control screw rod is threaded with the screw of second baffle; When needing; Rotatable control screw rod is removed its spacing to second damping block, thereby unclamps the clamping to adjusting rod, realizes the adjusting to headrest positions; Strengthen comfort; This product structure is simple, can manufacture, and has the extremely strong market competitiveness.

The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please referring to figs. 1 through shown in Figure 7, it has demonstrated the concrete structure of the utility model preferred embodiment, and a kind of chair head rest adjusting device comprises headrest 10, support member 20, first damping block 30, second damping block 40 and control piece 50, wherein:
The back side of said headrest 10 is provided with adjusting rod 11.
The upper end of said support member 20 is provided with first baffle plate 21 and second baffle 22 respect to one another, has a through hole 211 on this first baffle plate 21, has on the second baffle 22 between a screw 221, two baffle plates and has cavity 23.
Said first damping block 30, second damping block 40 is cylindrical and be installed on relative to one another in the cavity 23; Wherein, The outer face of first damping block 30 is provided with the joint pin 31 of an insertion through hole 211; The outer face of second damping block 40 is provided with the recess 41 superimposed with screw 221, and the inner face of two damping blocks is respectively equipped with the notch 32,42 of an opposed openings.
Said control piece 50 has a circular bottom plate 51 and a control screw rod 52; This control screw rod 52 is fixed on the base plate 51; And control screw rod 52 is threaded with screw 221 on the second baffle 22 and stretches into recess 41 second damping block 40 is withstood; Headrest 10 adjusting rod 11 passes the notch 32,42 of two damping blocks, by the notch of two damping blocks 32,42 it is fixedly clamped.
