Abstract
The utility model provides a bicycle, the height of a saddle seat of which can be optionally regulated in the process of running, and the saddle seat is composed of a seat cushion, an inner seat tube and an outer seat tube. The outer seat tube which is provided with a key groove is inserted in a back straight pipe of a frame of the bicycle, a lifting spring is arranged below the seat tube, and a tight clamping device and a clutch device of the seat tube are arranged at the upper end of the back straight pipe. When the utility model is operated, a pull wire is pulled, a clamp is opened by the push of a cam, at this time, a gap is generated between the tight clamping device and the outer seat tube, and the saddle seat can move from top to bottom under the action of the lifting spring and the weight of a human body; the pull wire is loosened, the saddle seat is fixed at any height. The utility model has the advantages of simple structure and flexible and convenient operation.
Description
The utility model relates to the bicycle that can regulate height in a kind of the travelling arbitrarily.
Because the saddle of existing bicycle is changeless when riding, safety when guaranteeing to ride, though saddle can be turned down, be convenient to biped and land, but unusual effort all when riding, and extremely uncomfortable, if saddle is heightened, though comfortable when riding, light, laborsaving, be absolutely unsafe but under situation about running into more than emergency situation or, the car many, ride, sometimes even can cause the generation of casualty accident the people.
When being a kind of riding is provided, the purpose of this utility model can regulate the jacking system of saddle height arbitrarily, with the safety of guaranteeing the cyclist and comfortable, laborsaving in riding.
The purpose of this utility model is achieved in that the saddle of being made up of seat cushion and inside and outside seat pipe is housed in the back straight tube of vehicle frame, the outer seat pipe that has a keyway is used for that fixed saddle makes it can not left-right rotation and limit the adjustable height of saddle, an interior seat pipe is used to regulate standing height makes it to be fit to the differing heights human needs, under the present pipe lifting spring is housed; The upper end of straight tube is welded and is useful on the fixed base plate that split or integral type fixing device are installed behind vehicle frame, the fixing device of elevating bracket pipe is installed between fixed base plate and the drop front, in riding, when the needs saddle raises, the pulling backguy, cam backs down fixing device and makes between outer seat pipe and the fixing device and produce the gap, saddle just can move up and down under the effect of lifting spring and human body weight, unclamp backguy, the clamped device of outer seat pipe is clamped, and saddle just is fixed on desired height.Brake synchronizer before and after on the straight tube of handle-bar, being equipped with, brake is changed into only with a brake lever before and after making each pipe of original left and right sides brake lever, another brake lever is used to handle the fixing device of saddle lifting, when brake, the pulling backguy, because the regulating action of pulley, the front and back brake is promptly worked simultaneously, and it is comparatively steady to brake.
The utility model compared with prior art has following advantage:
Saddle raises when riding, and makes the cyclist comfortable, light, laborsaving, when meeting red light or emergency situation, can reduce saddle rapidly, biped lands, and guarantees cyclist's safety, firmly stops, because of fixing by rubbing, saddle can stepless lifting and is operated steadily up and down between fixing device and the outer seat pipe.Since brake synchronizer before and after being equipped with, steady more, safety when making brake.The utility model is simple in structure, and is stable and reliable for performance, is suitable for uses such as person in middle and old age, student and women.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a sectional structural map of the present utility model.
Fig. 2 is used for the hoop that clamps between the inside and outside seat of the saddle pipe.
Fig. 3 is the drop front above the fixing device.
Fig. 4 is the fixed base plate on the straight tube behind vehicle frame that is welded.
Fig. 5 is the split fixing device.
Fig. 6 is the integral type fixing device.
Fig. 7 is the front and back brake synchronizers.
Among the figure: 1. straight tube 10. spring base 11. lifting springs, 12. bolts and hole 13. push rod bolts and hole 14. clamping devices, 15. bolts and hole 16. carrying rack of bicycle 17. bicycle racks, 18. bolts and hole 19. cam members, 20. return springs, 21. backguys 22. pressing plates 23. handle-bar straight tubes 24. brake synchronizer base plates 25. pulley yokes 26. pulleys 27. front brake backguys 28. rear braking backguys 29. brake control backguys 30. bolts 31. circular holes behind hoop 3. drop fronts 4. cushion rubber bumpers 5. fixed base plates 6. bolts 7. inner seat pipes 8. outer seat pipe 9. cycle frames that clamp between the seat cushion 2. inside and outside pipe.
In Fig. 1, saddle is by seat cushion 1, interior seat pipe 7 and outer pipe 8 constitute, the standing height of interior seat pipe 7 is regulated by the hoop 2 that clamps and is fixed, between fixing hoop 2 and drop front 3, cushion rubber bumper 4 is housed, fixing device 14 is installed in by between the fixing drop front 3 and fixed base plate 5 of 4 screws 18, the be welded upper end of behind vehicle frame straight tube 9 of fixed base plate 5, and lifting spring 11 is installed in the bottom of straight tube 9 behind the vehicle frame.
In Fig. 3, embodiment shown in Figure 4, the key of protrusion is arranged on the endoporus of drop front 3, insert during assembling in the keyway of outer seat pipe 8, being used for fixing saddle can not left-right rotation in making.4 screws 18 are used for fixing the fixing of base plate and drop front 3, and 2 screws 6 are used for the location of split (Fig. 5) fixing device 14, and circular hole 31 is used for cam 19 fixing of integral type (Fig. 6) fixing device 14.
In Fig. 5, embodiment shown in Figure 6, split (Fig. 5) fixing device 14 is made up of the spring of two band semicircles, opening device by cam 19 and push rod bolt 13, operate backguy 21 and pull back spring 20 is formed; Integral type (Fig. 6) fixing device 14 is to be processed by the monoblock spring leaf, opening device is that a cam 19 is installed between two spring leafs, during use, pulling backguy 21, cam 19 backs down shell fragment, at this moment produces the gap between outer seat pipe 8 of saddle and the fixing device 14, but saddle just up-and-down movement under lifting spring 11 and human body action of gravity, unclamp backguy 21, cam 19 is return under the effect of pull back spring 20, and fixing device 14 clamps seat pipe 8 outside the saddle automatically under the effect of spring leaf.
