Abstract
The invention relates to a connection structure for a saddle pipe and a front fork vertical pipe. The connection structure comprises a saddle pipe, a frame vehicle pipe and a quick-detaching locking sleeve, wherein the saddle pipe is inserted into the vehicle vertical pipe; and the quick-detaching locking sleeve is installed on the upper end part of a saddle vertical pipe. The connection structure is characterized by further comprising an upper pin rod, a lower pin rod and a connection plate, wherein the upper pin rod is installed on the inner side of the lower part of the saddle pipe; an axis of the upper pin rod is perpendicular to an axis of the saddle pipe; the lower pin rod is installed on the lower part of the inner side of the frame vehicle pipe; an axis of the lower pin rod is perpendicular to an axis of the frame vertical pipe; a puncture hole is formed in the lower end of the connection plate; the lower pin rod passes through the puncture hole; the upper part of the connection plate is provided with a long groove; and the upper pin rod passes through the long groove. The connection structure for the saddle pipe and the front fork vertical pipe can be conveniently adjusted; and the saddle can be prevented from being lost.
Description
Technical field
The invention belongs to technical field of bicycles, particularly relate to a kind of saddle pipe and vertical tube of front fork connection structure.
Background technology
Bicycle is the walking-replacing tool that in life, people commonly use, and has environmental protection, conveniently advantage.At present, along with people are to the continuous reinforcement of improving constantly of requiring of quality of the life and environmental consciousness, bicycle obtains the favor of increasing people.
In prior art, bicycle saddle pipe mounting structure comprises saddle pipe, seat tube and inserts lock sleeve soon, saddle pipe inserts seat tube from the upper end of seat tube, quick-detachment locking cover is arranged on the upper end of seat tube, for locking the relative position of saddle pipe and seat tube, thus height and position is carried out to the saddle being arranged on saddle pipe upper end fix.
The drawback of said structure is: open in the process that quick-detachment locking cover regulates saddle height, saddle pipe easily deflects, and saddle is produced cheap, after saddle height has regulated, must adjust, so make adjustment difficulty increase to saddle direction.In prior art, there is saddle pipe and seat tube and coordinate structure to limit saddle circumferential offset by the form of slot and inserted block, although this structure can avoid saddle to deflect in the process highly regulated, complex structure, processing and manufacturing difficulty.
Loosen quick-detachment locking cover, existing saddle pipe can directly be extracted out from seat tube, and saddle is easily lost.Some bicycles utilize bolt assembly to replace quick-detachment locking cover, and bolt assembly must use special tool dismantle, although so saddle can be avoided to lose, saddle inconvenience adjustment, antitheft be convenient to both adjustments and cannot take into account.
Summary of the invention
The present invention provides one to be convenient to regulate for solving in known technology the technical matters that exists, the saddle pipe that saddle can be avoided to lose and vertical tube of front fork connection structure.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is: a kind of saddle pipe and vertical tube of front fork connection structure, comprise saddle pipe, seat tube and quick-detachment locking cover, described saddle pipe plug-in mounting enters in described seat tube, described quick-detachment locking cover is arranged on the upper end of described saddle stand pipe, it is characterized in that: also comprise pin rod, lower pin rod and connecting plate, described upper pin rod is arranged on the lower inside of described saddle pipe, the axis of described upper pin rod and the axes normal of described saddle pipe, described lower pin rod is arranged on the lower inside of described seat tube, the axis of described lower pin rod and the axes normal of described seat tube, the lower end of described connecting plate is provided with perforation, described lower pin rod runs through described perforation, the top of described connecting plate is provided with elongated slot, described upper pin rod runs through described elongated slot.
The present invention can also adopt following technical measures:
Described lower pin rod is the bolt be arranged on by screw thread on described seat tube.
The advantage that the present invention has and good effect are:
The connecting plate cooperatively interacted in the present invention and upper pin rod can ensure that, in the process that saddle pipe is twitched up and down in seat tube, the saddle being arranged on saddle pipe upper end can not produce deflection, and saddle can be facilitated to regulate height.
While ensureing that saddle height is convenient to regulate, saddle pipe must utilize special tool can extract out from seat tube, saddle good anti-theft effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, saddle pipe; 2, seat tube; 3, quick-detachment locking cover; 4, upper pin rod; 5, lower pin rod; 6, connecting plate; 6-1, elongated slot.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of saddle pipe and vertical tube of front fork connection structure, comprise saddle pipe 1, seat tube 2, quick-detachment locking cover 3, upper pin rod 4, lower pin rod 5 and connecting plate 6, seat tube 2 is parts of cycle frame, and saddle is installed in the upper end of saddle pipe 1.The lower end of saddle pipe 1 is inserted seat tube 2 from the upper end of seat tube 2.Described quick-detachment locking cover 7 is arranged on the upper end of described seat tube 2.Quick-detachment locking cover 7 is prior art, for quick locking saddle pipe 1.
Described upper pin rod 4 is arranged on the lower inside of described saddle pipe 1, the described axis of upper pin rod 4 and the axes normal of described saddle pipe 1.Namely the bottom of saddle pipe 1 is provided with two jacks, and the two ends of upper pin rod 4 are inserted in two jacks, to realize the installation of upper pin rod 4.
Described lower pin rod 5 is arranged on the lower inside of described seat tube 2, the described axis of lower pin rod 5 and the axes normal of described seat tube 2.In the present embodiment, described lower pin rod 5 is the bolts be arranged on by screw thread on described seat tube 2, and namely the bottom of seat tube 2 is provided with two threaded holes, and bolt is fitted in holes by screw thread.
The lower end of described connecting plate 6 is provided with perforation, and described lower pin rod 5 runs through described perforation, realizes connecting of connecting plate 6 lower end and seat tube 2 with this.The top of described connecting plate 6 is provided with elongated slot 6-1, described upper pin rod 4 runs through described elongated slot 6-1, connecting of saddle pipe 1 and connecting plate 6 is realized with this, and ensure that saddle pipe 1 can be twitched up and down in seat tube 2, saddle pipe 1 is not by under the condition of instrument, can not extract out from seat tube 2 easily, there is anti-theft effect.
