The specific embodiment
In conjunction with Figure 1 and Figure 2, the lift armrest that present embodiment provides comprises: holder 1, movable shell 2, handrail holder 3 and lift adjustment assembly.
Holder 1 has department of assembly 11 and oblique straight-bar 12 (oblique straight-bar 12 is blocked by movable shell 2 among Fig. 1, asks for an interview perspective part and Fig. 5 of Fig. 2), and whole one-tenth is " 7 " font.Assembling stand 11 is provided with the screw hole 111 that is used to assemble, and fixes by screw, can be with whole armrest system fixing (in conjunction with Fig. 5) on the seat.Oblique straight-bar 12 is arranged on 11 tops, department of assembly, forms slanted angle with 11 planes, department of assembly, and oblique straight-bar 12 has a cavity 121, and differing heights is offered some draw-in grooves 122 (in conjunction with Fig. 3) on its sidewall, and oblique straight-bar 12 tops are provided with spacer pin 54.Oblique straight-bar 12 peripheries have two guide channel, are embedded with guide 123,124 in it respectively, are used for portable propelling shell 2 and slide, and play stabilization.
Movable shell 2 hollows are set in oblique straight-bar 12 outsides with being slidingly matched, and movable shell 2 upper ends are provided with supporting seat 21.Handrail holder 3 is fixedly installed on the supporting seat 21 by buckle and screw, forms " 7 " word shape with movable shell 2.
Described lift adjustment assembly comprises direction switch spare 51, elastic component 55 and snap device, direction switch spare 51 has the finger pressing section 511 and the actuating arm 512 of formation " 7 " font, its junction is arranged in the movable shell by rotating shaft 52 rotationally, it is outside for operation that movable shell 2 is stretched out in finger pressing section 511, specifically be that fluting by supporting seat 21 lower ends stretches out, actuating arm 512 stretches in the cavity 121 of oblique straight-bar 12.Described snap device comprises on the actuating arm 512 the described draw-in groove of offering on the fixture block 56 that is provided with and oblique straight-bar 12 sidewalls 122, separates to cooperate under the effect of manual piece and elastic component.In the present embodiment, the one-body molded rotating shaft 52 in the junction of finger pressing section 511 and actuating arm 512, rotating shaft 52 embeds in the rotary axis groove that provides on the movable shell 2, and the top is provided with briquetting 53, and briquetting 53 is compressed downwards by handrail holder 3.Elastic component 55 in the present embodiment is irregular shape shell fragment, is arranged on actuating arm 512 lower ends, replaces with oblique straight-bar 12 inwalls to cooperate.Fixture block 56 is arranged on actuating arm 512 bottom sides, fixture block 56 under direction switch spare 51 and elastic component 55 drives with oblique straight-bar 12 on draw-in groove 122 chuckings or separate, thereby locking or unclamp between control moving sleeve 2 and the oblique straight-bar 12.
As shown in Figure 3, when pushing finger pressing section 511, actuating arm 512 serves as axially to turn left to move elastic component 55 pressurizeds with rotating shaft 52, make the draw-in groove of offering on fixture block 56 and oblique straight-bar 12 sidewalls 122 separate, can regulate the height of the oblique relatively straight-bar 12 of moving sleeve 2 this moment; As shown in Figure 4, when loosening finger pressing section 511, elastic component 55 resets, and actuating arm 512 turns right, and fixture block 56 cooperates at the draw-in groove offered 122 under the elastic force effect and on oblique straight-bar 12 sidewalls, thereby realizes the location after the highly adjusting.
The spacer pin 54 that oblique straight-bar 12 tops are provided be used to limit the lift adjustment assembly relative to oblique straight-bar 12 upwards transition move.Handrail holder 3 makes handrail holder 3, moving sleeve 2 and lift adjustment assembly link into an integrated entity by briquetting 53 downward clamping shafts 52, can move up and down synchronously, referring to Fig. 5.
Below,, should not take off exposure scope of the present utility model based on simple replacement of the present utility model for those of ordinary skills only for the unrestricted the technical solution of the utility model of explanation.For example, the lift adjustment assembly can be other form, and the shape of direction switch spare 51 is not limited to " 7 " font, and 512 of its finger pressing section 511 and actuating arms form a suitable angle and get final product; Fixture block 56 can exchange with draw-in groove 22 positions; Rotating shaft 52 can be separate piece, cooperates with direction switch spare 51 versatilely; In addition, movable shell 2 upper ends can not be provided with special-purpose supporting seat 21, directly fixedly connected with handrail holder 3 or one-body molded.Oblique straight-bar 12 also can be one-body molded or fixedly connected ground mode is arranged on 11 tops, described department of assembly; In addition, be understandable that elastic component 55 can also adopt other form, as coil spring or torsion spring, certainly, elastic component also can be arranged on finger pressing section 511 or rotating shaft 52 places.
