Abstract
The utility model relates to the technical field of seat, especially a kind of armrest with damping, comprise the handrail body being fixedly mounted on seat support, in handrail body, offer handrail mounting hole, one side of handrail body is provided with through handrail mounting hole and is fixedly mounted on the handrail axle on seat support, and the opposite side of handrail body is provided with and relatively with handrail axle distributes and be fixedly mounted on the mount pad on seat support; Between handrail body and mount pad, be provided with disk spring, disk spring is coated on handrail axle.This is with the armrest of damping, and dumping force size is adjustable, and process and assemble is less demanding, is convenient to batch manufacturing.
Description
Technical field
The utility model relates to the technical field of seat, especially a kind of armrest with damping.
Background technology
Development along with Chinese Railway, it is great convenient that the train of high-speed cruising has brought to passenger's trip, passenger also has higher requirement to the traveling comfort of seat simultaneously, the handrail of existing seat is generally divided into fixed type handrail and turnup type handrail, turnup type handrail damping wherein adopts plastic sleeve more, rely on the interference fit between plastic sleeve and rotating shaft, when being rotated, handrail produces damping, processing, assembly precision are had relatively high expectations, and plastic sleeve is easy to wear, after long-time use, dumping force can decline.
And dumping force is non-adjustable, if the magnitude of interference of the rear rotating shaft of assembling and axle sleeve is excessive, can cause dumping force excessive, during passenger's rotary handle, operating effort is excessive, if the magnitude of interference of rotating shaft and axle sleeve is too small, can cause dumping force too small.Because the existence of Mismachining tolerance also can make the armrest of same batch, dumping force is variant simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, of the present utility modelly provide a kind of armrest with damping, tolerance on fit are little, and dumping force is adjustable.
The utility model solves the technical scheme that its technical matters adopts: a kind of armrest with damping, comprise the handrail body being fixedly mounted on seat support, in handrail body, offer handrail mounting hole, one side of handrail body is provided with through handrail mounting hole and is fixedly mounted on the handrail axle on seat support, and the opposite side of handrail body is provided with and relatively with handrail axle distributes and be fixedly mounted on the mount pad on seat support; Between handrail body and mount pad, be provided with disk spring, disk spring is coated on handrail axle.
The part causing for the dry friction of avoiding between handrail body and handrail axle weares and teares in advance, therefore be provided with self lubrication bearing between handrail axle and handrail body.
After making handrail axle be installed to mount pad, can not rotate, therefore be provided with flat of the first spline on handrail axle, the corresponding position of mount pad is provided with flat of the second spline.
In order to limit the angle of digging of handrail, therefore be provided with locating dowel pin on mount pad, on the correspondence position of handrail body, be provided with upper limit platform and lower limit platform.
For the ease of the installation or removal of handrail, therefore handrail body has detachable handrail lid.
The beneficial effects of the utility model are: by disk spring, provide dumping force, can reduce the tolerance on fit of axle and axle sleeve, thereby reduction processing charges, simultaneously can be by regulating the predetermincd tension of disk spring or to disk spring again type selecting, the dumping force of armrest can being regulated.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of mount pad;
Fig. 3 is use constitution diagram of the present utility model.
In figure: 1, handrail body, 1-1, detachable handrail lid, 1-2, handrail mounting hole, 1-3, upper limit platform, 1-4, lower limit platform, 2, handrail axle, flat of 2-1, the first spline, 3, mount pad, 3-1, locating dowel pin, flat of 3-2, the second spline, 4, self lubrication bearing, 5, disk spring, 6, seat support.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of armrest with damping as depicted in figs. 1 and 2, comprise the handrail body 1 being fixedly mounted on seat support 6, in handrail body 1, offer handrail mounting hole 1-2, one side of handrail body 1 is provided with through handrail mounting hole 1-2 and is fixedly mounted on the handrail axle 2 on seat support 6, and the opposite side of handrail body 1 is provided with and relatively with handrail axle 2 distributes and be fixedly mounted on the mount pad 3 on seat support 6; Between handrail body 1 and mount pad 3, be provided with disk spring 5, disk spring 5 is coated on handrail axle 2.The compressed generation spring force of disk spring 5, thus when handrail body 1 is rotated, there is dumping force, dumping force can be by regulating the predetermincd tension of disk spring 5 to regulate herein, or by disk spring 5 from new type selecting, also can damping adjusting power size.
Wherein, between handrail axle 2 and handrail body 1, be provided with self lubrication bearing 4, the part of avoiding the dry friction between handrail body 1 and handrail axle 2 to cause weares and teares in advance, has improved the service life of handrail.
On handrail axle 2, be provided with flat 2-1 of the first spline, the corresponding position of mount pad 3 is provided with flat 3-2 of the second spline, can not rotate after making handrail axle 2 be installed to mount pad 3.
On mount pad 3, be provided with locating dowel pin 3-1, on the correspondence position of handrail body 1, be provided with upper limit platform 1-3 and lower limit platform 1-4, after handrail installation, locating dowel pin 3-1 will stretch in the cavity of handrail body 1, by upper limit platform 1-3 and lower limit platform 1-4, can limit the rotational angle of locating dowel pin 3-1, thereby limit the angle of digging of handrail.
Handrail body 1 has detachable handrail lid 1-1, is convenient to the Assembly &Disassembly of handrail.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
