Abstract
The utility model relates to a kind of fixedly ball-type vibration-damping bicycle saddle pipe, comprise outer tube, inner tube and spring, it is characterized in that: the inwall of described outer tube is provided with at least two slideways with described outer axial tube line parallel, described slideway circumference uniform distribution is on the inwall of described outer tube, on the bottom outer wall of described inner tube, corresponding described each slideway is provided with elongated slot, in described each elongated slot, be provided with ball and maintain frame, described ball maintains some described elongated slot balls that are positioned at is installed on frame, the lower end that described ball maintains frame is connected with described inner tube by screw, the upper end of described outer tube is provided with spacing end cap by screw thread, described ball is positioned at the below of described spacing end cap.Therefore the utility model can guarantee that in saddle stability and vibrations process, noise is little.
Description
Technical field
The utility model belongs to technical field of bicycles, particularly relates to a kind of fixedly ball-type bicycle saddle pipe.
Background technology
Bicycle is the most traditional vehicle, and it has features convenient and swift, energy-conserving and environment-protective.At present, along with improving constantly of people's quality of the life, and the continuous reinforcement of the consciousness of people's environmental protection, bicycle is more and more used in people's life, especially the functional stronger bicycle such as mountain bike and highway car, becomes one way of life culture more and more welcomed by the people especially gradually.
Saddle pipe be on bicycle for the body of saddle is installed, saddle pipe is arranged on the middle pipe of cycle frame, saddle pipe is for supporting saddle, in conventional art, saddle pipe is to be inserted into the body on pipe in support body.Tradition saddle pipe does not have shock-absorbing function.My company has designed a kind of bicycle saddle pipe with shock-absorbing function, the patent No. is CN201320620692.0, this saddle pipe comprises inner and outer tubes and the spring of mutual plug-in mounting, inner tube can be carried out elastic telescopic by spring within the outer tube, outer tube is arranged on the vehicle frame of bicycle, and inner tube is used for supporting installation saddle, with this, realizes the shock-absorbing function of saddle pipe, there is simple in structure, good looking appearance, make the better comfortable advantage of cycling.But, in the process of manufacturing and finds disadvantage by user feedback: because will realize inner tube within the outer tube along axis activity, when assembling, between outer tube and inner tube, must there be gap, the existence in gap makes inner tube can produce slight rocking within the outer tube, cause saddle unstable, affect the overall performance of ride impression and bicycle.
Summary of the invention
The utility model provides a kind of fixedly ball-type vibration-damping bicycle saddle pipe that can guarantee that in saddle stability and vibrations process, noise is little for solving the circumferential unsettled technical matters of damping saddle pipe existing in known technology.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of fixedly ball-type vibration-damping bicycle saddle pipe, comprise outer tube, inner tube and spring, it is characterized in that: the inwall of described outer tube is provided with at least two slideways with described outer axial tube line parallel, described slideway circumference uniform distribution is on the inwall of described outer tube, on the bottom outer wall of described inner tube, corresponding described each slideway is provided with elongated slot, in described each elongated slot, be provided with ball and maintain frame, described ball maintains some described elongated slot balls that are positioned at is installed on frame, the lower end that described ball maintains frame is connected with described inner tube by screw, the upper end of described outer tube is provided with spacing end cap by screw thread, described ball is positioned at the below of described spacing end cap.
The utility model can also adopt following technical measures:
On the inwall of described outer tube, even circumferential is distributed with four slideways.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, between inner and outer tubes, add ball, several balls limit the circumferential and radial position of inner tube, thereby make installation saddle pipe on inner pipe more stable, and guarantee inner tube smooth and easy slip within the outer tube, make to ride more comfortable, improve the overall performance of bicycle.In addition, the position of ball maintains frame by ball and limits, and can avoid ball collision mutually in the process of rolling, and abates the noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, outer tube; 2, middle pipe; 3, quick detach; 4, inner tube; 5, spring; 6, upper head plate; 7, bottom plate; 8, slideway; 9, elongated slot; 10, ball; 11, spacing end cap; 12, ball maintains frame.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of free ball formula vibration-damping bicycle saddle pipe, comprises the outer tube 1 being arranged on middle tube of bicycle frame 2, and outer tube 1 is inserted in the middle pipe 2 of cycle frame, is provided with for locking the quick detach 3 of outer tube on middle pipe 2.In outer tube 1, be fitted with inner tube 4, the upper end of inner tube 4 is provided with for the saddle install portion of saddle is installed, and the inside of outer tube 1 is provided with spring 5, and spring 5 is located between outer tube 1 and inner tube 4, and the effect of spring 5 is to make the inner tube 2 can be at the interior elastic telescopic of outer tube 1.In the present embodiment, the upper end of spring 5 is connected with inner tube 4 by upper head plate 6, and the lower end of spring 5 is connected with outer tube 1 by bottom plate 7, and upper head plate 6 is welded on the inwall of inner tube 4, and bottom plate 7 is welded on the inwall of outer tube 1.
The inwall of outer tube 1 is provided with at least two slideways 8 with outer axial tube line parallel, slideway 8 circumference uniform distributions are on the inwall of outer tube 1, on the bottom outer wall of inner tube 4, corresponding each slideway 8 is provided with elongated slot 9, in each elongated slot 9, be provided with ball and maintain frame 12, ball maintains some elongated slot 9 balls 10 that are positioned at is installed on frame 12.The effect that ball maintains frame 12 is the position of spacing each ball 10, and to prevent between ball 10 collision mutually, to reduce the noise of inner tube 4 when axially movable in outer tube 1, the structure of the interior ball of its structure and ball bearing of main shaft is similar.The lower end that ball maintains frame 12 is connected with inner tube 4 bottoms by screw, and the upper end of outer tube 1 is provided with spacing end cap 11 by screw thread, and described ball 10 is positioned at the below of described spacing end cap 11.
