Abstract
The utility model relates to a light -duty bicycle frame structure, related frame include preceding riser, crossbeam, sloping, back riser and pitch the roof beam to one side, adorns crossbeam and sloping respectively admittedly with the plane between riser and the back riser in the front, adorns oblique fork roof beam admittedly at back riser rear side, adorns the line fixed establishment that brakes admittedly in the outside position of sloping, the lower part rear side system of back riser has bellied segmental arc forward, both ends the sheath line of brake line, the inside coaxial wire rope who wears dress brake line clamp. The riser passes through the design of segmental arc after this structure, effectually shortens wheel base preceding, the rear wheel, rides nimbly and freely. The location of not only having realized the brake line through brake line fixed establishment is fixed, and through adjusting the purpose that adjusting bolt realized adjusting the brake line, the regulative mode is simple, swift moreover, and the accuracy is high.
Description
Technical field
The utility model belongs to technical field of bicycles, especially a kind of light bike body frame structure for automotive.
Background technology
Bicycle also known as bicycle or bicycle, the normally two small-sized land-going machines of taking turns.After people rides car, being power with foot pedal, is the vehicle of environmental protection.
Finding through using, there are following two shortcomings in cycle frame:
1, very flexible, the wheelbase due to forward and backward wheel is subject to the restriction of Vehicle Frame Design, and wheelbase is fixed, stunt and very flexible.
2, the brake cable of bicycle is fixed on the cant beam of vehicle frame by traditional deck, plays the effect of fixing brake cable.After brake cable uses a period of time, due to frequent stretching, make brake cable elongated, tradition regulates the method for brake cable to be the brake cable that tension is positioned at front-wheel or rear frame portion, then by screw lock, realizes the object regulating brake cable.The regulative mode of above-mentioned brake cable is loaded down with trivial details, and adjustment poor accuracy, directly affects braking quality.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, ride flexibly, regulate brake cable conveniently light bike body frame structure for automotive.
Scheme of the present utility model is achieved in that
A kind of light bike body frame structure for automotive, involved vehicle frame comprises front standpipe, crossbeam, cant beam, rear profile tube and tiltedly pitches beam, between front standpipe and rear profile tube, isoplanar is fixedly mounted with crossbeam and cant beam respectively, be fixedly mounted with at the opposite side of rear profile tube and tiltedly pitch beam, be fixedly mounted with brake cable fixed mechanism in the outer fix of cant beam, the lower rearward side of described rear profile tube is shaped with segmental arc protruding forward;
The both ends of described brake cable fixed mechanism clamp the RVV of brake cable, the inner steel rope coaxially installing brake cable, concrete structure comprises permanent seat, locking is female and adjust bolt, one end of described adjustment bolt is connected with permanent seat coaxial threaded, and by locking is female, lock bolt and permanent seat are firmly linked together, coaxially clamp the wire bushing of brake cable in the outer end of this adjustment bolt, wire bushing is coaxially installed in this permanent seat outer end.
And described permanent seat upper end is integrally shaped with the arc fixed part be connected with cant beam.
Advantage of the present utility model and good effect are:
1, this structure rear profile tube is by the design of arc-shaped recess, and actv. shortens the wheelbase of front and rear wheel, rides nimbly and freely.
2, the location that this structure not only achieves brake cable by brake cable fixed mechanism is fixed, and the object by regulating adjustment bolt to realize regulating brake cable, and regulative mode is simple, quick, and accuracy rate is high.Utility model structure is simple, design science rationally, be skillfully constructed, brake cable regulates simple, has the value of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the structure cutaway view of the middle brake cable fixed mechanism of Fig. 1;
Fig. 3 is the structural representation of permanent seat in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of light bike body frame structure for automotive, as shown in Figure 1, involved vehicle frame comprises front standpipe 1, crossbeam 2, cant beam 4, rear profile tube 5 and tiltedly pitches beam 6, between front standpipe and rear profile tube, isoplanar is fixedly mounted with crossbeam and cant beam respectively, be fixedly mounted with at the opposite side of rear profile tube and tiltedly pitch beam, be fixedly mounted with brake cable fixed mechanism 3 in the outer fix of cant beam.
Innovative point of the present utility model is:
1, the lower rearward side of described rear profile tube is shaped with segmental arc 5A protruding forward, is effectively shortened the wheelbase of front and rear wheel, ride nimbly and freely by the design of segmental arc.
2, described brake cable fixed mechanism as shown in Figure 2, the both ends of this brake cable fixed mechanism clamp the RVV 7 of brake cable, the inner steel rope 8 coaxially installing brake cable, concrete structure comprises permanent seat 3C, locks female 3B and adjustment bolt 3A, one end of described adjustment bolt is connected with permanent seat coaxial threaded, and by locking is female, lock bolt and permanent seat are firmly linked together, coaxially clamp the wire bushing 7 of brake cable in the outer end of this adjustment bolt, wire bushing is coaxially installed in this permanent seat outer end.
As shown in Figure 3, its upper end is integrally shaped with the arc fixed part 3C-1 be connected with cant beam to the structure of described permanent seat.
Using method of the present utility model is:
When brake cable needs to regulate, first unscrew locking mother, then rotation adjustment bolt, in Fig. 2, the direction of arrow is the moving direction of adjustment bolt, will adjust bolt-locking after adjustment by locking mother.
Principle of work of the present utility model is:
By the length of mobile adjustment stud extender protecting sleeve in this structure, thus realize the object shortening steel rope, by steel rope tension, realize the object regulating brake cable.
The utility model has the advantages of for:
1, this structure rear profile tube bottom is by the design of segmental arc, and actv. shortens the wheelbase of front and rear wheel, rides nimbly and freely.
2, the location that this structure not only achieves brake cable by brake cable fixed mechanism is fixed, and the object by regulating adjustment bolt to realize regulating brake cable, and regulative mode is simple, quick, and accuracy rate is high.Utility model structure is simple, design science rationally, be skillfully constructed, brake cable regulates simple, has the value of wide popularization and application.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
