Description
Technical field
Bicycle accessories field is the utility model is related to, specifically a kind of bike saddle lever fixing apparatus.
Background technology
Bicycle seat pole is a kind of important accessory of bicycle, and its upper end is fixed with bicycle saddle cushion, lower end position can on
Under be adjustably fixed on cycle frame.Cycle frame is provided with seat pipe, and seat bar is inserted in seat pipe, utilizes clip, bolt, spiral shell
Mother fixes seat bar and seat pipe.In general, when user wants regulating seat cushion height, often first unscrew nut, then will
Seat bar is extracted out or is pressed into a bit of from seat pipe, finally tightens nut again.But unscrew and tighten nut and may result in nut
With the thread damage of bolt, clip is given the pressure of a bar and seat pipe contact surface and reduce, and then influence consolidating for seat bar and seat pipe
Determine effect.Meanwhile for some heavier people, seat bar is fixed with seat pipe only frictionally, consolidating between seat bar and seat pipe
Surely seem less firm.
Utility model content
In order to overcome the problem of reliability is not high, the utility model are fixed existing for existing bike saddle lever fixing apparatus
A kind of new bike saddle lever fixing apparatus is provided.
Technical scheme is used by the utility model solves its technical problem：A kind of bike saddle lever fixing apparatus, bag
Clip is included, seat cushion is connected by seat bar with seat pipe, it is characterized in that：Seat bar is fixed with seat pipe by clip and clamp button of the spring device；
Clamp button of the spring device is made up of the circle hole shape buckle in seat bar solid section, spring, through hole, buckle head and seat pipe；Seat bar is real
Center portion point is affixed to a solid cylinder on the inside of a bar, or seat bar core is solid, both ends are emptied；
There is a through hole along the radial direction of seat bar solid section and a spring is accommodated in the both sides of seat bar, through hole, the both ends point of spring
A buckle head is not fixed with；Each buckle head is protruding outside in the circular hole buckle circular hole in seat pipe.
Seat bar solid section is high（Length）For 2-5cm.The outside termination of buckle head is cone or rounding.Buckle head is
Double diameters, i.e., combined by two different cylinders in a manner of concentrically axis, the diameter in outside is less than circle hole shape buckle
Circularhole diameter, the diameter of inner side are more than the Circularhole diameter of circle hole shape buckle.Through hole and the diameter of buckle head are 3-7mm；Or
The internal diameter of through hole is bigger 0.02-0.10mm than the external diameter of buckle head.The center of spring is fixed on the center of through hole.
The technical program is on the basis of former fixing device, increases clamp button of the spring device to ensure the reliable of fixing device
Property.Seat bar main body can still use hollow-core construction, but the seat pipe of about 2 centimeter lengths will use solid construction, and in seat pipe
Solid-section, seat bar will be processed a through hole.The middle part of a piece spring will be fixed in the middle part of through hole, both ends of the spring point
The buckle head that a main body is cylinder is not fixed with.A series of symmetrical matched with buckle head can be processed in seat pipe
Circle hole shape buckle.When buckle head and circle hole shape are clasped, except clip is fixed between seat bar and seat pipe, also clamp button of the spring
The fixation of device, the utilization of two kinds of fixing devices will greatly improve the reliability of a lever fixing apparatus.
The beneficial effects of the utility model are can to greatly improve the reliability of bike saddle lever fixing apparatus, Er Qiejie
Structure is simple, cost is cheap, easy to operate.
Brief description of the drawings
Fig. 1 is the installation drawing of the present apparatus；
Fig. 2 is the enlarged drawing of the clamp button of the spring device of the present apparatus；
Wherein 1. seat cushions, 2. bars, 3. clips, 4. seat pipes, 5. clamp button of the spring devices, 6. bar solid sections, 7. springs,
8. through hole, 9. circle hole shape buckles, 10. buckle heads.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
A kind of novel seat lever fixing apparatus, adds clamp button of the spring device 5 in prior art basis.Seat cushion 1 passes through seat
Bar 2 is connected with seat pipe 4, and seat bar 2 is new by 5 two kinds of fixed forms of clip 3 and clamp button of the spring device, i.e. this practicality with seat pipe 4
The bicycle of type has two kinds of fasteners simultaneously.Clip 3 is fastener common on bicycle, no longer describes its work herein
Make principle.Clamp button of the spring device 5, mainly by the circle hole shape buckle 9 in seat bar solid section 6, spring 7, through hole 8, seat pipe and
Buckle head 10 is formed, and the radius of through hole 8 and buckle head 10 is 3-7mm（This is the design for meeting mathematical principle, is connect to reduce
Contacting surface is accumulated, and so as to reduce friction, needs to leave gap between through hole 8 and buckle head 10, it is proposed that the internal diameter of through hole 8 is than buckle head 10
The big 0.02-0.10mm of external diameter）.The solid cylinder that seat bar solid section 6 is an a height of 2-5cm, along the radial direction of cylinder
There is a through hole 8, the center of spring 7 is fixed on the center of through hole 8（Main purpose is to avoid buckle head 10 from being taken from through hole 8
Go out, influence fixed effect；It is not essential, i.e., the center of spring 7 can not be fixed, and it is double straight to be then improved to buckle head 10
Footpath, i.e., combined by two different cylinders in a manner of concentrically axis, the diameter in outside is less than the circular hole of circle hole shape buckle 9
Diameter, the diameter of inner side are more than the Circularhole diameter of circle hole shape buckle 9）, the both ends of spring 7 are respectively fixed with a buckle head 10.
There are a series of symmetrical circle hole shape buckles 9 matched with buckle head 10 in seat pipe 4, when buckle head 10 and circle hole shape buckle 9
During mutual cooperation, seat bar 2 will be more securely fixed in seat pipe 4.
The outside termination of buckle head 10 is cone, or the outside termination rounding of buckle head 10, and this is a kind of common
Processing mode, be advantageous in the presence of spring strength, be oriented to buckle head 10, so that the column part of buckle head 10 is easy
In the circular hole for stretching out circle hole shape buckle 9.
