Description

The multifunction bicycle auxiliary frame

Technical field

The utility model belongs to field of mechanical technique, is specifically related to a kind of multi-functional auxiliary frame that is installed on the bicycle.It can be adjusted to cyclist's backrest, may also be adjusted to the fluffy of sun-shading rain-proof.

Background technology

The structure that bicycle saddle cushion does not in the market have sunshade, keeps off the rain.If bicycle parking in the open, seat cushion suffers Exposure to Sunlight, drenches with rain, and people's buttocks is heated, is wet in the time of by bike, and is very uncomfortable; Long-distance cyclist or old cyclist do not have backrest reliable tired easily.

Summary of the invention

The purpose of this utility model is to propose a kind of multifunction bicycle auxiliary frame, when bicycle is not ridden, can sun-shading rain-proof to the vehicle seat pad, and can alleviate the long-time sensation of having a pain in the back after by bike of cyclist simultaneously again to a certain extent.

The utility model design-calculated multifunction bicycle auxiliary frame is made up of tressel 1 and control mechanism 2, and its structure as shown in Figure 1.Wherein, tressel 1 is made of corner frame 6 and baffle plate 8, corner frame 6 is connected to form by shelf 19 and pivoted arm rigidity, shelf 19 is that basic right angle is connected with pivoted arm 20 lower ends, pivoted arm 20 middle parts are fixed by the steel plate under the seat cushion 3 of turning cylinder 5 and bicycle, the upper part of pivoted arm 20 is a fulcrum with rotating shaft 5, is divided into 135 ° ± 5 ° (being generally 135 °) angles with its bottom, and pivoted arm 20 upper ends are connected with control telescopic shaft 4; Baffle plate 8 is connected with the latter half of shelf 19 by removable pin 7.Control mechanism 2 is used to control the schoolbag frame after tressel lies against bicycle, or holds up as backrest.

In the utility model, control mechanism 2 is by holding up pull bar 15, control telescopic shaft pull bar 14, pull-rod spring 12, telescopic shaft steel wire 9, holding up steel wire 10 and form, telescopic shaft steel wire 9, the leading section of holding up steel wire 10 are captiveed joint with pivoted arm 20 upper ends of tressel, the leading section of holding up pull bar 15 with hold up steel wire and be connected, the front end of control telescopic shaft pull bar 14 passes to be holded up pull bar and captives joint with telescopic shaft steel wire 9, and pull-rod spring 12 is arranged between the outside front end and shell 3 bottoms of holding up pull bar 15; Steel plate place at the bicycle saddle cushion downside has telescopic shaft fixed orifice 18, this hole 18 and end portion (vertical rod part) symmetry of pivoted arm upper extreme point about pivoted arm 20.Whole bicycle saddle cushion and auxiliary frame are fixing with the strut 17 of bicycle rack by check screw 16.

Auxiliary frame is under peacetime state, and baffle plate 8 is fitted with the shelf 19 of tressel.And put on the back pack support of bicycle.

When the cyclist feels fatigue, to hold up pull bar 15 and draw forward, and hold up steel wire 10 and make corner frame 6 begin upwards to hold up from the schoolbag frame position, control telescopic shaft 4 is moved position, B place to by position, A place, and it is interior locked to enter fixed orifice 18, thereby after being holded up, auxiliary frame 6 is fixed.When pull bar 15 drew forward, control telescopic shaft 14 pull bars also were drawn forward simultaneously, and the hold-doun nut 11 of rod end is with pull-rod spring 12 compressions.The shelf 19 of corner frame 6 has just become cyclist's backrest like this.

As cyclist during without backrest, one draw gently forward as long as will control telescopic lever 14, telescopic shaft 14 just is drawn out from fixed orifice 18, at this moment, pull-rod spring 12 will be holded up pull bar 15 to pusher, control telescopic shaft 14 so and just push back position, A place from the B position by spring 12.Corner frame 6 has been got back to former schoolbag frame place again at this moment.

When the cyclist in the open the time, holds up its bicycle parking with corner frame 6, its method of operation is the same, at this moment the plate washer on the shelf 19 8 is turned down again, and plate washer 8 has been protected seat cushion 13 like this, can remove from exposing to the sun and rain.

When cyclist's use is parked in open-air bicycle, as long as plate washer 8 is rolled up, because of sticking corner frame top on the plate washer 8.Telescopic shaft pull bar 14 is drawn forward gently, then corner frame 6 will fall down to schoolbag frame again, has recovered former state again.

The utility model is at the deficiency of existing bicycle saddle cushion and a kind of multifunction bicycle auxiliary frame that is installed on the seat cushion below that customized design is made, this also is applicable to motor bike, mini-motorcycle, battery-driven car, three-wheel vehicle, with the difference of bicycle auxiliary frame is the different of size and external form, and belongings are more convenient safer, also can make exploitation behind at it simultaneously.
