Description
Technical field
The utility model relates to technical field of bicycles, particularly relates to a kind of Split type bicycle frame.
Background technology
Bicycle is the vehicle that people commonly use.In existing cycle frame, bottom bracket axle is contained in Five-way tube, front pipe, saddle pipe, after get off fork be all fixedly connected with Five-way tube.Produce this vehicle frame and have two kinds of methods, a kind of is produce the various piece forming vehicle frame respectively, is welded on Five-way tube afterwards by modes such as solderings by other parts; Another kind is by realizing the one-body molded generation vehicle frame of mould constructed.This vehicle frame becomes to produce complex steps, high to the requirement of strength of Five-way tube, and the space that transport takies is comparatively large, and cost is higher.In addition, after this vehicle frame position is damaged, can not change, whole vehicle frame all can not reuse, and improves the use cost of bicycle.
Summary of the invention
Problem to be solved in the utility model is existing Integral frame, and production stage is loaded down with trivial details, takes up space large, is unfavorable for using.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of Split type bicycle frame.Described Split type bicycle frame, comprise saddle pipe and after to get off fork, also comprise sleeve pipe.The lower end of described saddle pipe is fixedly connected with a fixed block towards the side of rear wheel, described fixed block has the mounting hole holding sleeve pipe.Described casing pipe sleeve is contained in mounting hole, and the overall diameter of sleeve pipe matches with the interior diameter of mounting hole.Fork of getting off after described removably connects with sleeve pipe.
Further, fork of getting off after described is provided with set collar near one end of fixed block, the fixed orifice that the Kong Weiyu sleeve pipe of described set collar matches, and Fixing shrink ring is contained on sleeve pipe.
Preferably, the sidewall of described fixed orifice has the hold down groove that some axis uniform circular along fixed orifice distribute, the lateral wall of described sleeve pipe is provided with the fixing rib matched with described hold down groove.
Preferably, the sidewall of described mounting hole has the mounting groove matched with described fixing rib.
Further, the two ends of described mounting hole have annular groove, and the axis of described annular groove and the axis of mounting hole coincide, and the diameter of annular groove is greater than the diameter of mounting hole.
Preferably, described set collar has the flange of the ring-type matched with described annular groove on the side of fixed block.
Preferably, also comprise the pad be arranged in annular groove, the side of described pad and annular groove are fitted, opposite side and lip fits.
The advantage that the utility model has and good effect are: the Split type bicycle frame that (1) the utility model provides, saddle pipe and after get off fork split arrange, the two removably connects.Take up space little, be beneficial to transport, and the position of damage can be convenient for changing, reduce the use cost of bicycle.Saddle pipe with after fork of getting off can independently become to produce, by restriction each other, improve into product efficiency.(2), in the utility model, the lower end of saddle pipe is provided with a fixed block, after get off one end of fork be provided with set collar, sleeve pipe through the mounting hole on fixed block and set collar by saddle pipe and after fork of getting off fixing.During use, can install at the point-of-sale terminal of bicycle, storage space is little, quick and easy for installation.(3) in the utility model, the region that sleeve pipe is positioned at set collar and mounting hole is provided with fixing rib, matches with the mounting groove of the hold down groove in set collar and mounting hole, further firm connection.

Detailed description of the invention
In order to better understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is conducted further description.
As shown in figs 1 to 6, a kind of Split type bicycle frame, comprise saddle pipe 1, after to get off fork 3 and sleeve pipe 4.
The lower end of saddle pipe 1 is fixedly connected with a fixed block 2 towards the side of rear wheel, fixed block 2 has the mounting hole 201 holding sleeve pipe 4.Sleeve pipe 4 is sleeved in mounting hole 201, and the overall diameter of sleeve pipe 4 matches with the interior diameter of mounting hole 201.
After fork 3 of getting off be provided with set collar 301 near one end of fixed block 2, the fixed orifice 302 that the Kong Weiyu sleeve pipe 4 of set collar 301 matches, set collar 301 is sleeved on sleeve pipe, after fork 3 of getting off removably connected by set collar 301 and sleeve pipe 4.
As a kind of embodiment, the sidewall of fixed orifice 302 has the hold down groove 303 that some axis uniform circular along fixed orifice 302 distribute.The length of hold down groove 303 is identical with the degree of depth of fixed orifice 302, and the side from set collar 301 towards fixed block 2 extends to another side corresponding thereto.Hold down groove 303 is at least 2.The lateral wall of sleeve pipe 4 is provided with the fixing rib 401 matched with hold down groove 303.The sidewall of the mounting hole 201 of fixed block 2 has the mounting groove 202 matched with fixing rib 401.Sleeve pipe 4 plugs together in mounting hole 201 and fixed orifice 302, by fixing rib 401 and mounting groove 202 and hold down groove 303 coordinate fixing after to get off fork 3 and saddle pipe 1.The length of fixing rib 401 is less than the length of sleeve pipe 4.After installing, set collar is stretched out at the two ends of sleeve pipe 4, and the two ends of fixing rib 401 end at the side of set collar 301 away from fixed block 2.
As preferably, the two ends of mounting hole 201 have annular groove 203, and the axis of annular groove 203 and the axis of mounting hole 201 coincide, and the diameter of annular groove 203 is greater than the diameter of mounting hole 201.Pad 5 is provided with in annular groove 203.Set collar 301 has the flange 304 of the ring-type matched with annular groove 203 on the side of fixed block 2.Side and the annular groove 203 of pad 5 are fitted, and opposite side and flange 304 are fitted.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
