Description
Technical field
The utility model relates to a kind of armrests, and in particular, it relates to a kind of bi-directional adjustable armrests.
Background technology
In life, most of armrest be all be fixed on seat support unadjustable, but the people of different height, to handrail height need all be not quite similar.
At present, some seat on market, be provided with self-locking handrail lowering or hoisting gear, although the up-down adjustment of handrail height can be realized, meet the Man's Demands of differing heights, increase comfortableness, but self-locking handrail lowering or hoisting gear needs first handrail to be lifted to highest point, moving down from pinning, some inconvenience of regulative mode, complex structure, assembling difficulty is large.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bi-directional adjustable armrests, the height of adjustable handrail that can be convenient, meets the people of different height to the demand of armrest height, and structure is simple, and assembling is quick.
For achieving the above object, the utility model provides following technical scheme: a kind of bi-directional adjustable armrests, comprise armrest body, described armrest body bottom is connected with the base for being fixedly connected with seat support, described armrest body to be embedded in described base and can to slide up and down along described base inner wall, cavity is provided with in described armrest body, described armrest body outer wall offers the rectangle gathering sill with the through setting of described cavity along its length, described gathering sill both sides are provided with some spacing holes along described gathering sill setting direction gap, and all mutual with the described gathering sill UNICOM of each spacing hole, in described cavity, described gathering sill setting direction is provided with annular resilient collar, described elastic ring extends to form the limited block cooperatively interacted with described spacing hole to both sides, described elastic ring stretches formation button portion in described gathering sill epitaxial lateral overgrowth, described armrest body extenal fixation is connected with sleeve, and described sleeve outer surface is provided with the through hole for passing for described button portion.
By adopting technique scheme, when needs adjustable handrail height, press the button portion, annular elastomeric spring coil is under pressure and compresses in cavity, limited block is compressed in cavity from spacing hole, and then along sleeve lining upward sliding armrest body, when sliding into required height, put down button portion, annular elastomeric spring coil is subject to spring return, limited block and spacing hole get back to original position, and button portion and through hole are conflicted mutually, play fixation.This technical scheme can realize the adjustment of handrail height, meets the people of different height to the demand of armrest height, more convenient to operate, and structure is simple, and assembling is quick.
The utility model is set to further: described base comprises base plate and is embedded at the connecting portion in described base plate, described connecting portion side is provided with lug boss, on described base plate, correspondence position offers the groove be slidably matched with described lug boss, and described groove length is greater than described lug boss length.
By adopting technique scheme, connecting portion can slide in base plate along the groove cooperatively interacted and lug boss, thus changes the distance between handrail and the chair back, under meeting different sitting posture, people are to the demand of handrail, comfortableness is stronger, and flexibility is higher, and versatility is stronger.
The utility model is set to further: described connecting portion offers the first screwed hole for being fixedly connected with described base plate, and described base plate is provided with some second screwed holes in described first screwed hole correspondence position along described lug boss setting direction gap.
By adopting technique scheme, slide contact part to required position, and then realizes detachably fixing of the first screwed hole and the second screwed hole by securing member, and this structure can avoid relative sliding between connecting portion and base plate.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of bi-directional adjustable armrests of the utility model embodiment is described further.
A kind of bi-directional adjustable armrests, comprise armrest body 1, described armrest body 1 bottom is connected with the base 3 for being fixedly connected with seat support, described armrest body 1 to be embedded in described base 3 and can to slide up and down along described base 3 inwall, cavity is provided with in described armrest body 1, described armrest body 1 outer wall offers the rectangle gathering sill 11 with the through setting of described cavity along its length, described gathering sill 11 both sides are provided with some spacing holes 12 along described gathering sill 11 setting direction gap, and each spacing hole 12 all mutual UNICOMs with described gathering sill 11, in described cavity, described gathering sill 11 setting direction is provided with annular resilient collar, described elastic ring extends to form the limited block 21 cooperatively interacted with described spacing hole 12 to both sides, described elastic ring is stretched in described gathering sill 11 epitaxial lateral overgrowth and is formed button portion 22, described armrest body 1 extenal fixation is connected with sleeve 4, and described sleeve 4 outer surface is provided with the through hole for passing for described button portion 22.
By adopting technique scheme, when needs adjustable handrail height, press the button portion 22, annular elastomeric spring coil 2 is under pressure and compresses in cavity, limited block 21 is compressed in cavity from spacing hole 12, and then along sleeve 4 inwall upward sliding armrest body 1, when sliding into required height, put down button portion 22, annular elastomeric spring coil 2 is subject to spring return, limited block 21 and spacing hole 12 get back to original position, and button portion 22 and through hole are conflicted mutually, play fixation.This technical scheme can realize the adjustment of handrail height, meets the people of different height to the demand of armrest height, more convenient to operate, and structure is simple, and assembling is quick.
