Fig. 2 is structural schematic diagram of the utility model for the connecting tube of the connection structure of bicycle saddle tube.
Fig. 3 is bottom view figure of the utility model for the connecting tube of the connection structure of bicycle saddle tube.
Fig. 4 is structural schematic diagram of the utility model for the holding piece of the connection structure of bicycle saddle tube.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Referring to FIG. 1, a kind of connection structure for bicycle saddle tube, including seat pipe 10, standpipe 20 and connecting tube 30.
10 one end of seat pipe is removably arranged in connecting tube 30, and 30 one end of connecting tube is fixed on 20 upper end of standpipe.The upper tube 40 of bicycle
Connecting tube 30 is connected on Seat stay 50.
Fig. 2 and Fig. 4 are please referred to, threaded hole 31 and accommodating hole are offered in connecting tube 30, threaded hole 31 and accommodating hole connect
It is logical.Threaded regulating part is equipped in threaded hole 31, regulating part end is connected on the holding piece 32 being located in accommodating hole, and can
Holding piece 32 is pushed tightly to be connected to 10 outer wall of seat pipe.Specifically, regulating part is threaded bolt.
32 distal end faces 321 of holding piece and 10 outer wall of seat pipe are profile-followed, meanwhile, the cross-sectional area of holding piece 32, which is greater than, to be adjusted
The cross-sectional area of part.To improve the contact area of holding piece 32 Yu 10 outer wall of seat pipe.
32 distal end faces 321 of holding piece gradually protrude from top to bottom, form an inclined cambered surface.The inclined arc surfaced
32 end face of holding piece when so that holding piece 32 being tightly connected to 10 outer wall of seat pipe, needs to bear more pressures close to lower section side
Power, the pressure born close to upper side is relatively light, and the meeting pressure downward to seat pipe 10 after people is seated at vehicle seat, seat pipe 10 can
Energy meeting slide downward a small distance, holding piece 32 can deflect therewith under frictional force at this time, so that 32 top of holding piece
It is close with lower section stress, to improve the reliability of the positioning of seat pipe 10.
Threaded hole 31 is harmonious with 32 size of holding piece, meanwhile, threaded hole 31 is overlapped with accommodating centerline hole.So that regulating part
It is connected to 32 center of holding piece.To improve the stress under 32 working condition of holding piece.
Fig. 2 and Fig. 3 are please referred to, the upper tube 40 of tube wall towards the bicycle of 30 side of connecting tube is prominent to form the first protrusion
33,33 end of the first protrusion is protruded into upper tube 40 and is fixed.Connecting tube 30 with respect to the other side tube wall towards bicycle it is rear on
Fork 50 is prominent to form the second protrusion 34, offers weight loss groove 35 below the second protrusion 34.Second protrusion, 34 end furcations
Two branch portions arranged at predetermined angle are formed, branch portion protrudes into Seat stay 50 and fixes.First protrusion 33 and second convex
The top surface in portion 34 is a smooth curved surface out.
Threaded hole 31 is opened in the second protrusion 34, and the open at one end of threaded hole 31 is located between two branch portions.
A kind of bicycle, including upper tube and Seat stay, further include the connection structure for bicycle saddle tube, and connection structure is set
Between upper tube and Seat stay.
Connection structure disclosed by the utility model for bicycle saddle tube 10, seat pipe 10 are protruded into connecting tube 30, are tightened
Holding piece 32 is pressed on 10 outer wall of seat pipe by regulating part, and under frictional force effect, seat pipe 10 is highly fixed, and due to holding piece
The end face of 32 ends and seat pipe 10 are profile-followed, increase the contact area with seat pipe 10, fixed high reliablity.When being climbed,
Regulating part is unclamped, seat pipe 10 is removed from connecting tube 30, since seat pipe 10 is fixed in such a way that top is held, connecting tube 30 is not necessarily to
Upper tube 40 and 50 link position of Seat stay are stretched out, security risk is effectively eliminated.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
