Description
Technical field
The utility model relates to bicycle cast technical fields, and in particular to a kind of novel three chambers bicycle tube.
Background technique
Presently commercially available lithium electricity bicycle or cycle frame mostly use greatly typical round pipe, this design uses time mistake
Long, pipe intensity not enough will lead to middle pipe and buckling phenomenon occurs because in after vehicle frame finished product, and vehicle frame is caused to have security risk, while seat beam
(Fixture for tube of seat) be all be assemblied in above middle pipe, it is exposed above, aesthetic feeling is insufficient.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of novel three chambers bicycle tubes, to reach reinforcement vehicle
Frame self-strength, anti-stopping seat beam glide, and improve the safety of driving and the purpose of aesthetics.
In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of novel three chambers bicycle tube, it is described voluntarily
Vehicle pipe includes: round tube, and the round tube is connected with curved pipe by tube wall, is formed between the round tube and the curved pipe
Closed arc-shaped cavity, the round tube, arc-shaped cavity and curved pipe are integrally formed, round tube and arc at the top of the bicycle tube
A beam slot is provided between shape pipe.
It further, is trapezoidal chamber inside the curved pipe, the bottom of the trapezoidal chamber is indent circular arc type, the circle
The diameter of shape pipe is greater than the length of trapezoidal chamber bottom vertex line, the bicycle tube of the round tube and curved pipe composition
Cross section be three cavity structure of drops.
It further, is crescent chamber inside the curved pipe, the concave surface of the crescent chamber is close to round tube, the circle
The diameter of shape pipe is equal to the length of crescent chamber two end point connecting line, the bicycle tube that the round tube and the curved pipe form
Cross section is three cavity structure of strip, and the both ends of the strip are the arc of protrusion.
Further, which is characterized in that be provided with cap liner, the area and arc of the cap liner at the top of the curved pipe
The area of pipe cross section is identical.
The utility model has the advantages that
(1) the utility model by by three cavity structure of bicycle tube enhancing cycle frame entirety support strength.
(2) the utility model is on arc-shaped cavity by being arranged seat beam slot, by seat beam be partly hidden in round tube and curved pipe it
Between, anti-stopping seat beam slides, and enhances safety and the aesthetics of driving.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.
Fig. 1 is novel three chambers bicycle tube structural schematic diagram disclosed in the utility model embodiment；
Fig. 2 is water-drop-shaped vehicle tube section figure disclosed in the utility model embodiment；
Fig. 3 is strip vehicle tube section figure disclosed in the utility model embodiment；
Number and corresponding component title represented by letter in figure:
1, round tube；2, curved pipe；3, arc-shaped cavity；4, trapezoidal chamber；5, crescent chamber；6, seat beam slot.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The utility model provides a kind of novel three chambers bicycle tube, its working principle is that by by three type chamber of bicycle tube
The support strength of the enhancing cycle frame entirety of structure, then by the way that seat beam slot is arranged on arc-shaped cavity, seat beam is partly hidden in
Between round tube and curved pipe, reinforces vehicle frame self-strength to reach, improve the safety of driving and the purpose of aesthetics.
The utility model is described in further detail below with reference to embodiment and specific embodiment.
As shown in Figure 1-Figure 3, a kind of novel three chambers bicycle tube, the bicycle tube includes: round tube 1, the circle
Pipe 1 is connected with curved pipe 2 by tube wall, and closed arc-shaped cavity 3, the circle are formed between the round tube 1 and the curved pipe 2
Shape pipe 1, arc-shaped cavity 3 and curved pipe 2 are integrally formed, and are provided between the round tube 1 at the top of the bicycle tube and curved pipe 2
Seat beam slot 6.
It wherein, is trapezoidal chamber 4 inside the curved pipe 2, the bottom of the trapezoidal chamber 4 is indent circular arc type, the circle
The diameter of shape pipe 1 is greater than the length of trapezoidal 4 bottom vertex line of chamber, and the round tube 1 forms voluntarily with the curved pipe 2
The cross section of vehicle pipe is three cavity structure of drops.
It wherein, is crescent chamber 5 inside the curved pipe 2, the concave surface of the crescent chamber 5 is close to round tube 1, the circle
The diameter of shape pipe 1 is equal to the length of 5 two end point connecting line of crescent chamber, the bicycle of the round tube 1 and the curved pipe 2 composition
The cross section of pipe is three cavity structure of strip, and the both ends of the strip are the arc of protrusion.
Wherein, which is characterized in that cap liner, the area and curved pipe 2 of the cap liner are provided at the top of the curved pipe 2
The area of cross section is identical.
Wherein, Fig. 2 is the bicycle tube that cross section is drops.
Wherein, Fig. 3 is the bicycle tube that cross section is strip.
Three type chamber bicycle tubes are finished by turning after being integrally formed and output a beam slot 6 at the top of bicycle tube, are cooperated
Cap liner allows seat timing of getting one's things ready to sink, is partly hidden between round tube 1 and curved pipe 2, and seat beam is not fallen off,
Safety and aesthetics, the three lumen type bicycle tubes for increasing driving are more stronger than the support strength of typical round vehicle pipe, enhance certainly
It drives a vehicle the integral strength of itself vehicle frame.
It is worth noting that, the bicycle tube of the application can be applied to standard bicycle and lithium electricity bicycle.
Above-described is only the preferred embodiment of the novel three chambers bicycle of one kind disclosed in the utility model, should
It points out, for those of ordinary skill in the art, without departing from the concept of the present invention, can also do
Several modifications and improvements out, these are all within the protection scope of the present invention.
