Abstract
A foot pipe fixing device of a dynamic bicycle comprises foot pipes and a bottom bar. Each foot pipe is internally provided with a sleeve which is provided longitudinally. The sleeve is provided with internal screw threads. An end of the bottom bar is provided with a cover plate which is provided with screw holes. The cover plate is in threaded connection with the sleeves. The sleeves and the foot pipes are welded for forming. The cover plate and the bottom bar are formed integrally. According to the foot pipe fixing device of the dynamic bicycle, a longitudinally equipped sleeve is welded in each foot pipe, and screws are matched with the sleeves thereby effectively preventing a deformation problem of the foot pipe in screw fastening. The sleeves effectively improve strength of the foot pipes. Hexagon socket head cap screws can be adopted for connecting the sleeves with the cover plate thereby reducing the use cost, improving foot pipe stability, and obtaining higher safety and higher reliability in use. Furthermore the foot pipe fixing device of the dynamic bicycle has the following advantages: simple structure, low fabrication cost and good use effect.
Description
(1) technical field
The utility model relates to a kind of gymnasium body-building apparatus, specifically is a kind of pin pipe fixing device of Spinning.
(2) background technology
Existing Spinning, include vehicle frame, vehicle seat, pedal plate, wheel, bottom bar and pin pipe, the pin pipe directly is installed in the two ends of bottom bar by screw, normal screws is tightened the conference of exerting oneself with the distortion of pin pipe lock, and then there is the high problem of use cost in CARRIAGE BOLTS.
(3) summary of the invention
In order to solve the shortcoming that existing Spinning exists, the utility model provides a kind of pin pipe fixing device of Spinning, and the pin pipe is not yielding, and good stability.
For this reason, the utility model is taked following technical scheme:
A kind of pin pipe fixing device of Spinning includes pin pipe and bottom bar, is provided with the sleeve pipe of vertical layout in the described pin pipe, described sleeve pipe is provided with internal thread, the end of described bottom bar is provided with cover plate, and described cover plate is provided with screwed hole, and described cover plate is connected with casing threads.
Described sleeve pipe and pin pipe welding fabrication.
Described cover plate and bottom bar are one-body molded.
Employing the utlity model has following advantage: 1, the sleeve pipe of vertically arranging in pin pipe interior welds one, and screw cooperates with sleeve pipe, the problem on deformation that has produced when effectively having avoided pin Guan Zaisuo screw; 2, sleeve pipe has effectively strengthened the intensity of pin pipe, and the flat cheese head screw of hexagonal is connected sleeve pipe in can adopting with cover plate, has reduced use cost; 3, increased pin pipe stability, used safer, reliable; 4, simple in structure, cost of manufacture is low, result of use good.
