Description
Technical field
The utility model relates to bicycle accessories technical field, is specifically related to a kind of adjustable cycle frame.
Background technology
Due to the many upper ends upper pipe of bicycle being welded in head tube and standpipe in the market, in process by bike, be confined to the distance of bicycle handle bar and vehicle seat, human body needs that whole forward lean is carried out hand-held handlebar and controls direction, ride for a long time and make waist feel to ache, people many often directly body alleviate waist stress, but due to the arm limited length of people, straight body is just not easy to hold handle, easily because controlling party causes potential safety hazard to improper.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of adjustable cycle frame, and head tube can be moved forward and backward along upper pipe axis direction, thus drives the adjustment of handlebar position, meets people's comfort level by bike of different height.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of adjustable cycle frame, comprise head tube, standpipe, upper pipe, lower pipe, it is characterized in that: described upper pipe is divided into pipe leading portion and upper pipe back segment, described upper pipe leading portion external diameter is less than described upper pipe back segment external diameter, circular hole is provided with along described upper pipe axis direction in the middle of described head tube, described upper pipe leading portion is socketed in described circular hole, described head tube pipe leading portion can be slided on described, along being provided with multiple first screw perpendicular to described upper pipe leading portion axis direction on described upper pipe leading portion, upper and lower fastening structure is provided with above described head tube, described head tube is fixed on described upper pipe leading portion through described first screw by described upper and lower fastening structure, be socketed with one in described lower pipe and move sleeve pipe, the described mobile sleeve pipe other end is welded in described head tube.
Wherein, described upper and lower fastening structure comprises set collar, the upper and lower auricle be fixed on described set collar, L-type bolt, and described head tube is fixed on described upper pipe leading portion through described auricle and described first screw by described L-type bolt.
Further, the L-type bolt upper ring cap in the middle of described two auricles has multiple spring washer.
Wherein, the outer wall of described head tube is provided with multiple second screw, is fixed in described circular hole by the upper pipe leading portion of binding bolt by described upper pipe.
Wherein, described lower pipe outer wall is provided with multiple second screw, is fixed in described lower pipe by described mobile sleeve pipe by binding bolt.
The advantage that the utility model has and beneficial effect are: head tube can surpass standpipe direction and move forward and backward, thus adjusts handlebar front and back position, the people that can meet different height convenience by bike and comfort level.Multi-faceted reinforcing is carried out to movable members, has ensured stable property and the durability of vehicle frame.
Accompanying drawing explanation
Fig. 1 is the lateral plan of structure of the present utility model;
Fig. 2 is the birds-eye view of structure of the present utility model.
In figure: 1. head tube, 2. standpipe, 3. go up pipe back segment, 4. go up pipe leading portion, 5. set collar, 6. time pipe, 7. move sleeve pipe, 8. binding bolt, 9. auricle, 10. spring washer, 11.L type bolt, 12. first screws.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As Fig. 1, shown in Fig. 2, the utility model provides a kind of adjustable cycle frame, comprise head tube 1, standpipe 2, upper pipe, lower pipe 6, it is characterized in that: described upper pipe is divided into pipe leading portion 4 and upper pipe back segment 3, described upper pipe leading portion 4 external diameter is less than described upper pipe back segment 3 external diameter, circular hole is provided with along described upper pipe axis direction in the middle of described head tube 1, described upper pipe leading portion 4 is socketed in described circular hole, described head tube 1 pipe leading portion 4 can be slided on described, along being provided with multiple first screw 12 perpendicular to described upper pipe leading portion 4 axis direction on described upper pipe leading portion 4, upper and lower fastening structure is provided with above described head tube 1, described head tube 1 is fixed on described upper pipe leading portion 4 through described first screw 12 by described upper and lower fastening structure, be socketed with one in described lower pipe 6 and move sleeve pipe 7, described mobile sleeve pipe 7 other end is welded in described head tube 1.
Wherein, described upper and lower fastening structure comprises set collar 5, upper and lower auricle 9, the L-type bolt 11 be fixed on described set collar 5, and described head tube 1 is fixed on described upper pipe leading portion 4 with described first screw 12 through described auricle 9 by described L-type bolt 11.
