Description

The handrail lifting structure

Technical field

The utility model relates to the matching component of seat, exactly is adjustable for height seat lifting handrail.

Background technology

The conventional seat adjustable armrest is various informative, as Chinese patent CN03210768.4 disclosed " a kind of handrail of regulating lifting ", it is mainly by armrest support, shell, regulate spanner, spring, fork, interior patch, parts such as cover plate are formed, one end of its armrest support is fixedlyed connected with seat support by screw, whole handrail is installed on the seat support, the other end activity of armrest support is engaged in the interior patch, interior patch plug is in shell, fix with cover plate above, one end of interior patch has the fork hook, one end activity of fork is engaged on this hook, there is locating shaft the fork other end one side, and the lifting tooth that locating shaft passes on interior patch and the armrest support cooperates, there is movable axis the another side, movable axis is inserted in the waist hole of regulating spanner, regulates the opposite side that the spanner activity is engaged in shell, by pulling the adjusting spanner, make handrail be in the height of comfortable, regulate the back height that finishes and to pin automatically.But its structure is comparatively complicated, cost of manufacture is higher, also breaks down easily, inconvenient maintenance.

The utility model content

At the deficiency that prior art exists, the utility model aim to provide a kind of simple in structure, be convenient to assemble and the handrail lifting structure of stable performance.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of handrail lifting structure, comprise handrail shell and handrail steel pipe, the inside of described handrail steel pipe is provided with garment bag, the inside of handrail shell is provided with garment bag and slides up and down the T type frame that cooperates, be provided with plastic cement pull bar moving up and down in the slideway of T type frame, be provided with spring between the briquetting of the upper end of plastic cement pull bar and plastic cement pull bar and be connected with button on the handrail shell, the lower end takes the form of inclined plane, be set with fixture block on it, T type frame is provided with fixture block perforation and corresponding position limiting structure, and garment bag is provided with one and arranges the kerve that tightens mutually with fixture block.

Described briquetting is riveted mutually and is covered on the plastic cement pull bar with T type frame, offers on the plastic cement pull bar and the corresponding slotted hole of briquetting rivet.

Described briquetting has two, and the compartment of terrain is riveted on the T type frame.

One side of described garment bag has the logical opening that outwards slits.

The position limiting structure of described fixture block is made up of the projection of fixture block perforation both sides.

Match by the inclined-plane of skewed slot with plastic cement pull bar lower end in described fixture block inside.

The width of described plastic cement pull bar lower end dwindles in the middle of two side direction.

The slideway upper end of described T type frame is provided with rivet, and the upper end of plastic cement pull bar offers corresponding slotted hole.

The utility model is compared with the existing handrail of regulating, loaded down with trivial details parts such as interior patch have been saved, handrail shell and handrail steel pipe garment bag and the T type frame by inside slides up and down and cooperates, tighten mutually with kerve by plastic tie control fixture block, greatly simplified structure, slide up and down more steadily, be difficult for breaking down, it is more stable not only to be convenient to assembling and performance.

Fig. 2 is the internal structure schematic diagram of the utility model after removing handrail shell and handrail steel pipe;

Fig. 3 is a decomposition texture schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1--handrail shell 2--handrail steel pipe

3--garment bag 4--T type frame

5--plastic cement pull bar 6--briquetting

7--spring 8--button

9--slotted hole 10--fixture block

11--fixture block perforation 12--projection

The 13--kerve

Shown in Fig. 1～3, this handrail lifting structure mainly is made up of handrail shell 1 and handrail steel pipe 2, wherein the inside of handrail steel pipe 2 is provided with garment bag 3, one side of this garment bag has the logical opening that outwards slits, so that other parts are installed, the inside of handrail shell 1 is provided with garment bag and slides up and down the T type frame 4 that cooperates, be provided with plastic cement pull bar 5 moving up and down in the slideway of T type frame 4, be provided with spring 7 between the briquetting 6 of the upper end of plastic cement pull bar 5 and plastic cement pull bar and be connected with button 8 on the handrail shell, briquetting 6 has two, the compartment of terrain is riveted on the T type frame 4, and cover on plastic cement pull bar 5, offer two and the corresponding slotted hole 9 of briquetting rivet on the plastic cement pull bar 5, under the restriction of briquetting 6, can control plastic tie 5 by button 8 moves up and down reposefully, the outside perk in the lower end of plastic cement pull bar 5 takes the form of inclined plane, width dwindles in the middle of two side direction, be set with fixture block 10 on it, match by the inclined-plane of skewed slot with plastic cement pull bar lower end in fixture block inside, the position limiting structure that T type frame 4 is provided with fixture block perforation 11 and is made up of the projection 12 of fixture block perforation both sides, guaranteeing 10 of fixture blocks sidesway and can not deviating from the fixture block perforation, garment bag 3 is provided with the kerve 13 that a row and fixture block 10 tighten mutually.

Operation principle of the present utility model is: fixture block is enclosed within on the inclined-plane of plastic cement pull bar lower end, when plastic cement pull bar during at lowest order, fixture block is in the least significant end on pull bar inclined-plane, at this moment fixture block is stuck in the kerve the inside of garment bag, handrail is elevated to any one section can block support, when the plastic cement pull bar is up carried, the inclined-plane of pull bar along with on move the kerve that makes the fixture block sidesway go out garment bag, so just can flexible modulation, behind the release button, pull bar resets again under the effect of spring and armrest lock is fixed on desired height.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.For example after the slideway upper end of T type frame was provided with rivet, the upper end of plastic cement pull bar set out corresponding slotted hole, to guarantee stationarity that it moves up and down or the like.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
