Abstract

The utility model discloses an alternative swing bicycle saddle with gears, which comprises a vertical tube, a crossbar swing part and two cushion components, wherein the crossbar swing part is connected with the vertical tube, and the two cushion components are arranged on the crossbar swing part for connecting the two cushion components. The alternative swing bicycle saddle with gears adopting the technical scheme has the advantage that the left cushion component and the right cushion component can rotate reversely and alternatively centering on a cross shaft by the aid of a unique transmission structure formed by bevel teeth. When the technical scheme is compared with the scheme mentioned in the background art, cushions well fit to bearing points of the hip of a user, namely two bone point areas on the lower side of the pelvis of the user, so that the alternative swing bicycle saddle with the gears is accordant with the human engineering theory when being ridden on, causes no harm to reproductive systems for both males and females and is capable of greatly improving reproductive quality. In addition, by the aid of pressure springs sleeved outside adjusting screws arranged on the cushion components, adjusting nuts and stop screw caps, amplitude, angle and bearing strength of saddling boards can be adjusted, so that the alternative swing bicycle saddle with the gears is capable of meeting riding preference of more people.

Description

Gear alternative expression swing bicycle saddle

Technical field:

The utility model relates to bicycle manufacturing technology field, is specially a kind of gear alternative expression swing bicycle saddle.

Background technology:

Existing bicycle is the single fixedly vehicle seat of design usually; The main simple function that supports the people's buttocks of riding that rises, its structure is simple relatively, but its vehicle seat in the process of riding contacts the contact condition that can not be in the best with the buttocks of human body; Vehicle seat and human body thigh root produce friction in riding for a long time; Cause sense of discomfort, particularly in long-distance riding, very easily cause wound.Form owing to vehicle seat is a stationary state in addition, the pedaling of people in riding, and the vehicle seat that is is in discordant cycle status to the reaction pressure of human body, makes the automobile people feel very uncomfortable, also causes fatigue easily.For addressing the above problem, Chinese patent CN86202623U discloses a kind of alternatively swinging formula vehicle seat, its two-seater design to the effect that; And two-seater with T shape bar fixing with vehicle frame on; Seat is arranged at T shape bar two ends respectively, and the pendulum hinge is set on the T shape bar, and fork is hinged by bearing pin and pendulum; Two front ends connect drive link separately respectively, and drive link is connected to the fork two ends.Through the design of such drive mechanism, realize left and right sides vehicle seat alternating movement, and then alleviate cyclist's sense of discomfort.But still having following shortcoming, this drive mechanism also needs to improve; That is: 1, the anglec of rotation before and after the vehicle seat receives very big restriction; 2, vehicle seat is in the rotation of front and back; Receive fork and pin down, generation swings, but the mode of this swing can make the cyclist produce new sense of discomfort.

The utility model content:

The technical matters that the utility model solves provides a kind of gear alternative expression swing bicycle saddle; The drive mechanism that its design is new; Realize that the anglec of rotation before and after the vehicle seat is unrestricted, and the vehicle seat effect that can not swing, satisfy different cyclists' the custom that scrunches; It is more comfortable to ride, and degree can lessen fatigue.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

Gear alternative expression swing bicycle saddle; Comprise standpipe and with standpipe bonded assembly cross bar goods of furniture for display rather than for use be arranged at two groups of cushion assemblies on the bonded assembly cross bar goods of furniture for display rather than for use, said cross bar goods of furniture for display rather than for use comprises transverse axis, is sheathed on two groups of single armed axles on the transverse axis, the abutting end of two groups of single armed axles is connected with the power transmission bevel gear through key respectively; The transverse axis center wears straight pin, and the straight pin two ends are provided with umbrella tooth idle wheel, and umbrella tooth idle wheel is mutually meshing with the power transmission bevel gear; On the transverse axis between two power transmission bevel gears center is set, center is arranged with support sleeve outward; The outer square tube assembly that is used for umbrella tooth idle wheel and power transmission bevel gear that is provided with of umbrella tooth idle wheel, the two ends of square tube assembly respectively be movably set in transverse axis on single armed overlap and captive joint; The transverse axis two ends are provided with the circlip for shaft that compresses the single armed axle.

Said cushion assembly comprises that seat board and front end prop up board component through axle sleeve hinge pivotally attached; Seat board free end bottom is provided with the hinged set screw that is provided with; Set screw is arranged with pressure spring outward; Setting nut is arranged at the set screw top of a board component upper part, and a board component and terminal the setting by nut are passed through in the set screw lower end, and the cushion assembly is through captiveing joint with the single armed axle with bolt connection piece with a board component bonded assembly clamp.

Captive joint with the square tube assembly through the fastening connection piece with loam cake and lower cover in said standpipe upper end, on cover and be provided for the screw that is fastenedly connected with the square tube assembly.

The good effect of the utility model technical scheme is the drive mechanism that unique umbrella tooth makes up; Two cushion assemblies can alternately replace backward rotation around transverse axis about realization; Scheme corner with respect to mentioning in the background technology is bigger, makes that cushion and people's the stress point of buttocks is the regional fine applying of two place's bones points of people's pelvis downside, and ergonomic is theoretical when riding; Men and women's reproductive system is not had any injury, the fertility quality is had great raising.The set screw of cushion assembly setting is arranged with pressure spring outward in addition, and setting nut and by nut, can regulate amplitude, the angle of seat board and receive force intensity, can satisfy more people's the preference of riding.
