Abstract

The utility model relates to a damping bicycle seat which belongs to the technical filed of a bicycle saddle. The damping bicycle seat aims at solving the problem that a damping bicycle seat with simple structure and long service life is provided. The damping bicycle seat adopts the proposal that a seat face, a rigid supporting body, a connecting frame and vertical columns connected with a bicycle stand are included; buffer retaining pieces are fixed at the middle parts of the vertical columns; buffer springs are all installed on the vertical columns on both sides of each retaining piece; a spring is installed in a sleeve with a flanging at the upper end and a guide piece with a rotatable limiting retaining tongue and nuts connected with the threads of the vertical columns of the bicycle are installed on the vertical columns at the upper end of the sleeve. The utility model has the advantages of simple and compact structure and good damping effect.

Description

The damping bicycle seat

Technical field

The utility model relates to a kind of damping bicycle seat, belongs to the bicycle saddle technical field.

Background technology

Existing bike saddle generally by seat surface, rigid support, steel wire link span, be located at upright spring of two damping spirals between steel wire link span rear end and the rigid support and the component set-ups such as insertion pipe that are connected with seat tube.Comfortable in order to drive, the rigid support of the vehicle seat that has is designed to framed structure, sets up a plurality of cylindroid helical-coil extension springs in framework.Its weak point is that above-mentioned bike saddle structure is complicated, and parts are fragile, and particularly damping performance is poor, drives the person's of riding fatiguability.When especially under the bad situation of road conditions, growing distance travel, can make and drive the person of riding and quicken to increase sense of fatigue.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of damping bicycle seat of simple in structure, long service life.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of damping bicycle seat, it comprise seat surface, rigid support, link span and with bicycle rack bonded assembly column, said column middle part is fixed with the buffering catch, on the column of both sides recoil spring is housed all about the catch, spring is loaded in the sleeve of upper end band flanging, and the guide piece of band rotary spacing retaining tongue and the locknut that is threaded with the bicycle rack standpipe are housed on the column of sleeve upper end.

Above-mentioned damping bicycle seat, said link span lower end and column are fixed, the link span upper end is hinged with rigid support, and the axis of hinge is arranged along the y direction of rigid support, each fixes one or two curved plate spring along fore-and-aft direction in the link span both sides, and the upper end of spring contacts with the lower surface of rigid support.

The upright spring that damping bicycle seat provided by the utility model is arranged side by side former two of being located between rigid support and the link span is cast out need not, but on the column of vehicle seat, set up parts such as buffering catch, recoil spring and sleeve, and by means of with the damping that connects and composes of bicycle rack standpipe, like this, make the structure of this vehicle seat become simpler, compact, good damping effect, and help prolonging service life of each parts of vehicle seat.In addition, adopt the pivotally attached mode between rigid support of this vehicle seat and link span, and, can obviously improve the comfort of driver in the process of riding, and can obviously alleviate the sense of fatigue of long-time driving in conjunction with the support of steel spring.

Description of drawings

Fig. 1 is that scheme drawing is looked on the right side of Fig. 2 of a kind of embodiment of the utility model;

Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1.

Number in the figure is: 1, bicycle rack standpipe, 2, sleeve, 3, rotary spacing retaining tongue, 4, guide piece, 5, locknut, 6, column, 7, link span, 8, steel spring, 9, rigid support, 10, seat surface, 11, hinge, 12, the buffering catch, 13, recoil spring, 14, recoil spring, 15, flanging

The specific embodiment

Below in conjunction with the embodiment accompanying drawing the utility model is done further auspicious stating.

See accompanying drawing, damping bicycle seat provided by the utility model is the improvement on former bike saddle basis, comprise seat surface 10, rigid support 9, link span 7 during it constitutes and be welded with buffering catch 12 with bicycle rack standpipe 1 bonded assembly column 6, column 6 middle parts, one cylindrical screw compression recoil spring 14,13 all is housed on the column 6 of catch both sides about in the of 12, spring 13,14 is loaded on the upper end and is provided with in the sleeve 2 of flanging 15, and the guide piece 4 of band rotary spacing retaining tongue 3 and the locknut 5 that is threaded with bicycle rack standpipe 1 are housed on the column 6 of sleeve 2 upper ends.Link span 7 changes the steel plate link span into by former steel wire link span.The lower end of link span 7 adopts screw, nut to captive joint with 6 on column.Link span 7 upper ends adopt hinge to be connected with 9 of rigid supports, the axis of the hinge 11 of hinge is arranged along the y direction of rigid support 9, and each fixes one or two curved plate spring 8 with screw, nut along fore-and-aft direction in the link span both sides, the upper end of spring 8 contacts with the lower surface of rigid support 9, plays the effect of rigidity of support supporter 9 and seat surface 10.

For prevent vehicle seat in use the relative proper motion vehicle frame rotate, can be square at its buffering catch 12 with the Cross-section Design on top with column 6, and with guide piece 4 on square pilot hole bearing fit.When installing and using, after passing breach set on the flanging of sleeve 2, the rotary spacing retaining tongue 3 on the guide piece 4 is embedded in the set groove in bicycle rack standpipe 1 upper end.In addition, 4 versions that also can adopt key and keyway of column 6 and guide piece are used for realizing the purpose that prevents that vehicle seat relative proper motion vehicle frame from rotating.

During installation, the flanging 15 of sleeve 2 is overlapped on the upper end of bicycle rack standpipe 1, and pushes down by guide piece 4, is locked with locknut 5.
