Description

A kind of thing to sit on head rest lowering or hoisting gear

Technical field

The utility model relates to a kind of thing to sit on head rest lowering or hoisting gear, belongs to furniture and makes the field.

Background technology

Raising along with living standards of the people, requirement to thing to sit on is also more and more higher, for meeting the needs of, the thing to sit on kind of manufacturer's exploitation is also more and more, wherein the use of chair is extensive especially, people at home, office etc. all be unable to do without chair, the personage of office particularly, be sitting on the chair for a long time, requirement to chair is very high, more comfortable in order to use, head rest is generally all arranged on chair, but traditional head rest is generally fixed, and the people's who uses height and different, it is also uncomfortable when most people use, height adjustable head rest is also arranged, but existing head rest adjusting device or too complicated, damage easily, perhaps regulate inconvenient, a kind of head rest adjusting device that provides as Chinese utility model patent seat chair with adjustable head rest structure (2005200354784), regulate height with swivel head by the way that makes the bolt that is fixed together with head rest screw in the screw thread of fixing with the chair back, use inconvenience and stability also bad, develop a kind of simple in structure, easy to use and safe and reliable head rest lowering or hoisting gear is the task of top priority of thing to sit on industry.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, develops a kind of head rest lowering or hoisting gear, requires to have simple in structure, handling ease, advantage economical and practical, easy to use.

The purpose of this utility model is realized by following technical scheme.A kind of thing to sit on head rest lowering or hoisting gear, by outside plate, inner panel and slide block are formed, the centre of described inner panel offers a rectangle window, be provided with a posting in the outside of described window, two vertical limits of posting become concavo-convex, described slide block comprises head and afterbody, the both sides of its head are outstanding, outstanding both sides are provided with cantilever, one end of cantilever is fixed on the head body, one location salient point is arranged on the other end, offer chute on the end face of head, described slider head stretches into the inner panel window, its ledge is pressed on two vertical limits of window, positioning convex point on the cantilever is placed on the recess of posting, described outside plate is provided with two slide rails, outside plate covers inner panel outside and is fixed together and slide rail is placed in the chute, also can on two vertical limits of window, limit guide rail be set, on four angles of afterbody, locating piece is set at the slider head ledge, slider head stretches into the inner panel window, its ledge is pressed on two vertical limits of window, and locating piece is stuck in the outside of limit guide rail.As preferably, 6 cylinders that have draw-in groove are set on inner panel, on the correspondence position of outside plate, offer 6 locating holes that built-in spring is arranged, outside plate covers on the inner panel, and cylinder inserts in the hole, and spring snaps in draw-in groove is fixed together outside plate and inner panel.

During use, on outside plate, coat sponge and thing to sit on lining, after slide block stretched into window, outside plate and inner panel are fixed together, the afterbody and the chair back rack of slide block are fixed together, head rest is moved up or down, because the cantilever on the slide block has elasticity, positioning convex point on the cantilever slides on the rabbet of posting, and the concave point that the positioning convex point on the cantilever is absorbed on the posting when not applying power makes head rest rest on selected position, reach the effect of regulating the head rest position,, have corresponding chute on the slider head owing to have slide rail on the outside plate, make the slip of slide block have directionality accurately, if the reverse side at slider head is provided with several locating pieces, on two limits of window, limit guide rail is set again, its slip is more reliable.

In the utility model, adopt slide block on guide rail, to slide, rely on the concavo-convex position of cantilever salient point on posting to make and be skillfully constructed the head rest location, adopt outside plate, inner panel and slide block package assembly, easy to process, assembling is simple, each parts is hot pressing injection moulding one-shot forming all, technology is simple, with low cost, and it is easy to adjust when using, safe and reliable, therefore, the utlity model has simple in structure, handling ease, advantage economical and practical, easy to use.
