Abstract

The utility model relates to a seat telescopic armrest, comprising an armrest body, an armrest outer shell as well as an armrest plate. Wherein the armrest body is sheathed in the armrest outer shell, the armrest plate is arranged at the top of the armrest outer shell. Positioning holes in complex number which are longitudinally arranged are arranged on the armrest body, a rotating rod is inserted into the armrest outer shell, an eccentric spring plate is arranged on the rotating rod, the eccentric spring plate is contacted against an inner wall of the armrest outer shell, an inversed hook which is adapted with the positioning holes is arranged at the lower edge of the rotating rod. A push switch which controls the rotating of the rotating rod is arranged on the armrest outer shell. Thereby, the combination between the inversed hook at the lower edge of the rotating rod and the positioning holes on the armrest body is adjusted through the push switch, so that the armrest outer shell can be flexed freely opposite to the armrest body, thereby the efficacy that the height of the armrest can be adjusted is achieved. Meanwhile, the inversed hook of the rotating rod can be impelled to clamp with the corresponded positioning hole tightly by utilizing the eccentric spring plate, thereby the stable using of the armrest is ensured effectively. In addition, the overall assembly is convenient, and the structure is compact, the practicality is strong.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.

See also Fig. 1 to shown in Figure 7, a kind of seat extension/retraction handrail comprises armrest body 10, handrail shell 20 and balustrade panel 30, wherein:

10 times ora terminalis of this armrest body are installed with connecting plate 40, and this connecting plate 40 is to provide affixed with seat; This armrest body 10 is provided with the locating hole 11 of a plurality of vertical arrangements, when adjusting to predetermined altitude, forms location structure for following overhead kick engaging.Ora terminalis is installed with the buckle 12 of restriction handrail shell 20 slippages on this armrest body 10.

This handrail shell 20 is placed in outside the armrest body 10, make armrest body 10 be positioned at handrail shell 20, and this handrail shell 20 can go to upper and lower along this armrest body 10 mobile, undertaken simultaneously by the buckle 12 of ora terminalis on the armrest body 10 spacing, in case handrail shell 20 complete slippage armrest bodies 10; Be fitted with a dwang 50 in this handrail shell 20, described dwang 50 upper ends are provided with a turning cylinder 51, this turning cylinder 51 is installed in handrail shell 20 tops, and these turning cylinder 51 tops are being pressed by a sheet metal 60, this sheet metal 60 is to be locked on the handrail shell 20, to guarantee that turning cylinder 51 can outwards not move, dwang 50 is fixed.These dwang 50 rear side one are extended an eccentric shell fragment 52 (certainly should off-centre shell fragment can also be to assemble on the dwang separately); This off-centre shell fragment 52 is and handrail shell 20 inwalls are conflicted, these dwang 50 front side lower edges be provided with one with armrest body on the adaptive overhead kick 53 of locating hole 11; Be positioned at handrail shell 20 and be provided with the push switch 70 that a control dwang 50 rotates, push switch 70 is to be made of button 71 and spring 72, the medial extremity of this button 71 convexes with reference column 711, this spring 72 is to be set on this reference column 711, described handrail shell 20 is provided with a containing hole 21, this button 71 is to be flush-mounted in this containing hole 21, the outboard end of button 71 is exposed to outside the handrail shell 20, and the reference column 711 of button 71 medial extremitys is installed in the slotted eye 54 on the dwang 50, and described spring 72 1 ends are tight against and are against on the dwang 50.

This balustrade panel 30 is installed in handrail shell 20 tops; This balustrade panel 30 comprises a handrail panel 31 and a sliding panel 32, this sliding panel 32 is locked on the handrail shell 20 by bolt 33, this handrail panel 31 is provided with a chute 311, and this chute 311 is flush-mounted in sliding panel 32 both sides, handrail panel 31 is along sliding panel 32 horizontally slips.Described sliding panel 32 both sides are provided with wave-like protrusions 321, offer a plurality of and protruding 321 recessed 312 of cooperating on 311 liang of inwalls of the chute of described handrail panel 31, so handrail panel 31 can reach position-limiting action in sliding process, strengthens preferable feel also for the user when operation.

During assembling, described handrail shell 20 is set in outside the armrest body 10, and buckle 12 is installed on armrest body 10 upper ends with the 20 complete slippages of restriction handrail shell; Then dwang 50 is inserted along handrail shell 20, make turning cylinder 51 be installed in handrail shell 20 tops, assemble push switch 70 then, the overhead kick 53 of dwang 50 is to be stuck in the locating hole 12 (to see shown in Figure 3) under the normality, to form location situation; Again sheet metal 60 is pressed in turning cylinder 51 tops, simultaneously with the sliding panel 32 of balustrade panel 30 in the lump by bolt 33 lockings, so this sheet metal 60 can limit turning cylinder 51 and up deviates from; Handrail panel 31 with balustrade panel 30 is buckled on the sliding panel 32 at last, and handrail panel 31 can be horizontally slipped along sliding panel 32.

When needs are regulated height, press push switch 70 along the F1 direction in advance, causing dwang 50 after the actuation button 71 is that fulcrum is swung with its turning cylinder 51, this moment, the eccentric shell fragment 52 of dwang 50 was in compressive state, and the overhead kick 53 of dwang 50 lower edges can break away from former locating hole 12 (seeing shown in Figure 4), handrail shell 20 can be made progress or lower slider along armrest body 10, when being adjusted to predetermined altitude, unclamp push switch 70, this dwang 50 be the fulcrum backswing with turning cylinder 51 under 52 effects of eccentric shell fragment, and overhead kick 53 at this moment snaps in accordingly again and promptly forms positioning action (seeing shown in Figure 5) in another locating hole 12; When needs were regulated balustrade panel 30 positions, moving hand-rail panel 31 can make handrail panel 31 horizontally slip along sliding panel 32 directions and get final product (seeing Fig. 6, shown in Figure 7).

Cooperate between the locating hole on the overhead kick that the utility model design focal point is to adjust the dwang lower edge by push switch and the armrest body, make on the relative armrest body of handrail shell and carry out freely stretching, thereby reach the effect of handrail adjustable-height, to be fit to different personage's needs; Wherein the overhead kick of dwang cooperates system to impel the two closely engaging by the elastic force of eccentric shell fragment set on the dwang with corresponding locating hole, guarantee the stable use of handrail effectively, and because this off-centre shell fragment system defaults on the dwang, so during assembling dwang is inserted the arrangement of finishing eccentric shell fragment in the handrail shell, make whole assembly convenient, and compact conformation, practical.

The above, it only is the preferred embodiment of the utility model structure, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
