Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of stair railing, referring to Fig.1 shown in, including the handrail 3 that is fixedly connected at the top of column 2, column 2 with
And the cross bar 4 that the bottom of column 2 passes through, the part for being pierced by cross bar 4 are fixedly connected with pedestal 1, pedestal 1 is fixed on stair.
Referring to shown in Fig. 2 and Fig. 3, column 2 includes telescopic rod 1, the bottom fixed on the bottom of telescopic rod 1 and stair
Seat 1 is fixedly connected on one, offers opening 211, inside of the telescopic rod 1 lower than opening 211 at the top of telescopic rod 1
Bar shaped sliding slot 23 is offered, the width of bar shaped sliding slot 23 is less than the width of opening 211, slidably connects and stretch in bar shaped sliding slot 23
Contracting bar 2 22, be open 211 size be equal to telescopic rod 2 22 thickness, have limited section 221 in the bottom protrusion of telescopic rod 2 22,
When telescopic rod 2 22 slides into the top of telescopic rod 1, contradicted at limited section 221 and opening 211, so that telescopic rod two
22 bottom is limited to the top of bar shaped sliding slot 23, to prevent telescopic rod 2 22 from skidding off out of telescopic rod 1.
Shown in referring to Fig.1, the top of telescopic rod 2 22 is fixedly connected with handrail 3, and the upper surface of handrail 3 is smooth, reduces hand
The frictional force of handrail 3.In the corner of handrail 3, arc transition is set by handrail 3, can prevent user from not having because of handrail 3
Transition or other transition cause the hand of user to empty above column 2, reduce the balance of user.
Referring to shown in Fig. 4 and Fig. 5, it is fixed with driving assembly 5 in the bottom at the both ends of handrail 3, driving assembly 5 includes cylinder
513 and cover on the shell 51 on cylinder 513 (see Fig. 1).The top of shell 51 offers outlet 514, opens up inside shell 51
There is width to be less than the slideway 511 of outlet 514, push rod 512 is slidably connected in slideway 511, the width of push rod 512 is equal to outlet
514 width, push rod 512 can slide at outlet 514, and the two sides protrusion in 512 bottom of push rod has sliding part 5121, slides
The inner wall of portion 5121 and slideway 511, which slides, to be contradicted, can anti-throw-out lever 512 slipped from the outlet of shell 51 514.
The piston rod of cylinder 513 is fixedly connected on the bottom of push rod 512 along the centerline direction of shell 51, cylinder 513
The inside of pedestal 1 is fixed in bottom, and pedestal 1 is fixed on stair, and then improves the stability of cylinder 513.
The lower surface that is on one side fixed in handrail 3 of the push rod 512 far from cylinder 513 is pushed away when cylinder 513 moves reciprocatingly
Bar 512 pushes handrail 3 to move upwards along centerline direction, interior at the top of the sliding part 5121 of the bottom of push rod 512 and slideway 511
Surface fitting, and then the position of fixed push rod 512, make push rod 512 that handrail 3 be driven to raise, to facilitate the higher user of height
It can get a grip on the rail 3, keep stability when stair activity.
The course of work: starting cylinder 513 makes cylinder 513 drive push rod 512 that handrail 3 is pushed to move upwards, when push rod 512
The inner surface at 511 top of sliding part 5121 and slideway of bottom when being bonded, the position of push rod 512 is fixed；It is pushed away in push rod 512
When dynamic handrail 3 moves upwards, the telescopic rod 2 22 being fixedly connected with handrail 3 slides into limited section 221 and item along bar shaped sliding slot 23
The inner wall of shape sliding slot 23 is bonded, and then is lifted up handrail 3 integrally, increases the height of handrail 3.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
