Description
Technical field
The utility model relates to bicycle arts, particularly relate to a kind of cycle frame.
Background technique
Bicycle is a kind of vehicles common in daily life, can be used to go on a journey to ride instead of walk, environmentally protective.Bicycle
It can also be used as the tool of exercise and contest, bicycle race has become popular sports campaign.In sports,
Very high requirement is proposed to bicycle overall structure.Lighter, the existing cycle frame one for pursuit bicycle body
As be made of composite material, there is high-intensitive, low weight characteristic, vehicle frame is that integrated molding or pipe fitting are spliced.
Therefore, in the market when producing above-mentioned bicycle frame made of composite materials, there are two types of production methods: first is that taking one
Formula molding directly produces entire vehicle frame；Second is that first producing pipe fitting, then formed after pipe fitting is assembled with other accessories.Both methods
These require to wear air hose in advance, are formed by way of wind pressure, lead to that there are many defects: operating to operator horizontal
Height is sought advice, and product quality is largely dependent on the experience and operation technique of operator, misoperation will lead to interior
Portion generates folding line when wind pressure, influences product strength, fraction defective is higher；The requirement of pressure and air blowing to wind pressure is stringent, life
It is longer to produce working hour, it is difficult to meet requirements of mass production.Therefore, the bicycle frame made of composite materials of existing structure forms difficulty
Greatly, it is difficult to meet the requirement of market mass production.
In view of this, the designer, which is directed in said structure design not attain, improves caused many missings and inconvenience, and
Deeply design, and actively research improvement has a fling at and develops and design the utility model.
Utility model content
The purpose of this utility model is to provide a kind of structures simple, easy molding, cycle frame easy to produce.
In order to achieve the above objectives, the solution of the utility model is:
A kind of cycle frame, the vehicle frame is made of two symmetrical accessories, including left accessory and right accessory, left accessory
It is in mirror symmetry with right accessory.
The accessory is spliced by more semicanals, and the semicanal includes front fork semicanal, upper tube half, lower tube half, seat semicanal
With left back chainstay；One end of the upper tube half is connected to the outside of front fork semicanal, and the other end of upper tube half is connected to a semicanal
Upper outside；One end of the lower tube half is connected to the outside of front fork semicanal, and the other end of lower tube half is connected by five logical semicanals
It is connected to the lower end of a semicanal；The left back chainstay is connected to the lower end of a semicanal by five logical semicanals.
The front fork tube is equipped with the handle through slot cooperated for hundle-bar.
The upper end of the seat semicanal is formed with the mounting groove to install bicycle saddle.
The five logical semicanal is equipped with the foot-operated mounting hole installed for bicycle pedals.
After adopting the above structure, the utility model structure is simple, left accessory and right accessory can directly by mold at
Type is easy production molding, and the inside creasing that can be generated to avoid existing wind pressure technique, accessory stay in grade, intensity are high；On
Stating structure cycle frame can simplify production technology, can be improved production efficiency, be suitable for batch production.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the left accessory front view of the utility model；
Fig. 4 is the right accessory front view of the utility model.
Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
For sake of convenience, hereinafter "upper" "lower" " left side " " right side " is consistent with the direction up and down of attached drawing itself but not right
The utility model structure plays restriction effect.
As shown in Figures 1 to 4, a kind of cycle frame is made of comprising left accessory 1 and the right side two symmetrical accessories
Accessory 2, left accessory 1, which is sticked together with right accessory 2 in mirror symmetry and gluing, is combined into complete vehicle frame.Due to left accessory 1, right accessory
2 is symmetrical, now illustrates detailed structure by taking left accessory 1 as an example.Left accessory 1 is spliced by more semicanals, before above-mentioned semicanal includes
Pitch semicanal 11, upper tube half 12, lower tube half 13, seat semicanal 14 and left back chainstay 15.
As shown in figure 3, above-mentioned front fork semicanal 11 and the setting of 14 side by side parallel of seat semicanal, front fork semicanal 11 are equipped with for bicycle
The handle through slot 110 of handle cooperation.Upper tube half 12, lower tube half 13 are arranged between front fork semicanal 11 and seat semicanal 14.Upper half
One end of pipe 12 is connected to the outside of front fork semicanal 11, and the other end of upper tube half 12 is connected to the upper outside of a semicanal 14.Under
One end of semicanal 13 is connected to the outside of front fork semicanal 11, and positioned at the lower section of upper tube half 12, the other end of lower tube half 13 passes through five
