Abstract

Disclosed is a bicycle shock-proof seat, which is composed of a shock absorber, a back seat bracket, a back seat fixer, a back seat pad, armrests and a back backrest. Wherein, the shock absorber is provided with a shock-proof manifold branch screwed with an external thread; a shock-proof spring is sleeved on the exterior of the shock-proof spring; a shock-proof spring lower bracket with an internal thread is arranged at the lower end of the shock-proof spring; a shock-proof spring upper bracket with an internal thread is arranged at the upper end of the shock-proof spring; a shock-proof pole support is thread- arranged in the upper bracket; the lower part of the shock-proof pole support is extended into the shock-proof manifold branch; the lower end of the shock-proof manifold branch is fixedly connected with the bicycle frame, and the upper end of the shock-proof pole support is connected with the lower end of the back seat bracket; the shock absorber is arranged in the lower parts of the two sides of the back seat bracket; the armrests are respectively arranged in the front part of the back seat bracket; the back backrest is arranged in the back part of the back seat bracket; and the back seat pad is also added. Thus, the bicycle shock-proof seat is more applicable to the children for seating, and not only safety is ensured but also buttocks pain caused by the jounce is avoided, extremely applicable to riding on uneven road surface. The utility model has the advantages of simple structure, convenient operation, safety and reliability and obvious shock-proof effect.

Description

Shock-absorbing rear seat of bicycle

Technical field

The utility model relates to the technical field of bicycle, belongs to a kind of shock-absorbing rear seat of bicycle.

Background technology

At present, existing bicycle and man, its back seat generally all is rigidly connected, and does not have shock absorption device, when children ride on the back seat, travels down in injustice, can feel the pain of buttock of jolting, very uncomfortable, though there is the people that sponge is installed on back seat, play certain cushioning effect, but then can not tackle the problem at its root for potholed road.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to use, significant shock-absorbing rear seat of bicycle of damping effect.

For achieving the above object, the utility model is taked following design plan: a kind of shock-absorbing rear seat of bicycle, it is by bumper, back mounting, back mounting fixer, back seat cushion, handrail, back backrest constitutes, it is characterized in that: described bumper is provided with one and is with the outer vibration damping tubes of detaining, this shock-absorbing shake arm outside is with vibration damping spring, the vibration damping spring lower end be provided be with in the button the holder of vibration damping spring lower bracket, on vibration damping spring, be provided with the vibration damping spring upper bracket holder of button in being with, in the holder of vibration damping spring upper bracket, placed shock-absorbing pole, the bottom of this shock-absorbing pole puts in the vibration damping tubes, captive joint with vehicle frame in the lower end of this vibration damping tubes, the upper end of this shock-absorbing pole is connected with the rear sitting rack lower end.

Button outside on vibration damping tubes, being with, with the vibration damping spring lower bracket holder of button in being with and vibration damping spring lower bracket holder captive nut be screwed to tighten on the vibration damping tubes appropriate location fixing, the top of shock-absorbing pole, bottom all are with screw thread, the vibration damping spring upper bracket holder of buckleing is screwed into shock-absorbing pole top with upper bracket holder captive nut and in being with, bottom shock-absorbing pole is socketed with inner ring sleeve, be provided with the upper and lower back-up ring of inner ring sleeve in the upper and lower part of inner ring sleeve, one locknut be housed in the lower end of following back-up ring.

In order to take safety, in the front portion of back mounting handrail is installed, at the rear portion of back mounting the back backrest is installed.

In order to improve the damping, buffering effect, on the mounting of back, seat cushion is installed.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of shock-absorbing rear seat of bicycle, it is by bumper 1, back mounting 2, back mounting fixer 13, back seat cushion 20, handrail 3, back backrest 4 constitutes, its described bumper 1 is provided with a vibration damping tubes 9, these vibration damping tubes 9 outsides are with vibration damping spring 10, be provided with vibration damping spring lower bracket holder 11 in vibration damping spring 10 lower ends, be provided with vibration damping spring upper bracket holder 6 in vibration damping spring 10 upper ends, in vibration damping spring upper bracket holder 6, placed a shock-absorbing pole 8, the bottom of this shock-absorbing pole 8 puts in the vibration damping tubes 9, captive joint with vehicle frame 21 in the lower end of this vibration damping tubes 9, the upper end of this shock-absorbing pole 8 is connected with mounting 2 lower ends, back.

The outer wall of vibration damping tubes 9 is with outer button (see figure 2), in being with, buckle vibration damping spring lower bracket holder 11 inwalls (see figure 5), tighten the appropriate location that vibration damping spring lower bracket holder captive nut 12 and vibration damping spring lower bracket holder 11 are screwed to vibration damping tubes 9 fixing, in also being with, buckles the inwall of vibration damping spring upper bracket holder 6 (see figure 6), the appropriate location that vibration damping spring upper bracket holder captive nut 5 and vibration damping spring upper bracket holder 6 is screwed to shock-absorbing pole 8 tops is tightened fixing, adjusting the upper and lower support restitope of vibration damping spring puts, can compress or loosen vibration damping spring 10, thereby play the effect of increase and decrease vibration damping spring elastic force.

The upper and lower of shock-absorbing pole 8 is with screw thread, be with inner ring sleeve 17 in the bottom of shock-absorbing pole 8, be socketed with back-up ring 19 in the upper end of inner ring sleeve 17, be socketed with back-up ring 16 down in the lower end of inner ring sleeve 17, on the lower end shock-absorbing pole of following back-up ring 16, a locknut 14 is housed.

In order to take safety, in the front portion of back mounting 2 handrail 3 is installed, back backrest 4 is installed at its rear portion.

In order to improve the damping, buffering effect, on the mounting 2 of back, seat cushion 20 is installed.

Vibration damping tubes 9 usefulness seamless tubes are made, outer wall is with outer button, upper end open, the lower end is flattened and is sealed, and vibration damping spring lower bracket holder captive nut 12 and vibration damping spring lower bracket holder 11 is screwed on the vibration damping tubes 9, according to different automobile types such as bicycle 24 vehicles, 26 vehicles, turn and adjust the locknut 14 under the back-up ring 16 under vibration damping spring lower bracket holder captive nut 12 and vibration damping spring lower bracket holder 11 and shock-absorbing pole 8 lower ends, after making mounting inclination angle, back suitable, tighten fixingly, install with the bicycle that adapts to different size.

Vibration damping spring upper bracket holder 6 can be played the effect of supporting vibration damping spring 10, turn simultaneously the upper bracket holder downwards, upwards turn the lower bracket holder and can play compression vibration damping spring 10, increase the effect of vibration damping spring elastic force, otherwise then can reduce vibration damping spring elastic force, take more comfortablely with the people who adapts to different weight, and needn't change vibration damping spring.Inner ring sleeve 17 upper and lower back-up rings can play the effect of stablizing shock-absorbing pole and accepting inner ring sleeve, after back-up ring 19 is fixed with jackscrew 18 with shock-absorbing pole on the inner ring sleeve, can play the effect that prevents that back-up ring from gliding and shock-absorbing pole is deviate from from vibration damping tubes.

At bottom, mounting both sides, back mounting shock absorber, at the anterior handrail of installing of back mounting, the back backrest is installed at the rear portion, adds seat cushion, is more suitable for children's ride-on, and both safety had waist, the pain of buttock that can eliminate jolts causes, and use on the road surface that is fit to very much the road injustice.
