Abstract

The utility model discloses a tyre pump placed on a bicycle saddle tube. The tyre pump placed on a bicycle saddle tube is also suitable for a man-powered tricycle and a power-assisted bicycle with a saddle tube. A piston rod with a piston is arranged in the saddle tube. A pumping handle is a link mechanism. An air outlet at the bottom of the saddle tube is connected with an air hose. A valve inside clamp is fixed on the saddle tube by a spring clamp. When in use, only a telescopic handle is pulled out to the maximum of the saddle tube, and then the handle is winged up and down to pump; when riding, the telescopic handle is put down, which is convenient. The utility model has the advantages of simple structure and easy fabrication.

Description

A kind of pump-up device of being located on the bicycle saddle pipe

The utility model relates to a kind of pump-up device, relates in particular to a kind of pump-up device of being located on the bicycle saddle pipe.Also be applicable to manual tricycle and the morpet of saddle pipe is arranged.

Existing bicycle does not generally have pump-up device, can't inflate at any time during the tire unsaturated vapor in the way by bike, does not locate for rider's one big inconvenience in fact, for this reason some producer's customized design portable inflator, but it is little also to exist the air-capacitor amount, wastes time and energy when inflating, and easily loses.

The purpose of this utility model is to overcome above-mentioned weak point, and designs a kind of pump-up device of being located on the bicycle saddle pipe, only need pull out telescopic handle during use to this pipe when the longest, swing up and down handle, can inflate, put down getting final product in the time of by bike, very convenient, can not lose.

The technical solution of the utility model is: the piston rod that has piston is housed in the saddle pipe, piston rod is made up of the steel pipe of large and small two screw thread sockets, vehicle seat is installed in the big steel pipe upper end, little steel pipe lower end connects piston, the bottom of saddle pipe offers an air gate, it links to each other with high pressure tank, and air hose links to each other with high pressure tank, and the valve inside clip of air hose can be fixed on the saddle pipe by spring clip; Inflating bat-handle is a connecting rod mechanism, wherein side link one end and telescopic handle bar are rotatably connected, the other end is fixed in the spline joint piece, the spline joint piece is fixed on the saddle pipe, and connecting rod one end and telescopic handle bar are rotatably connected, the other end is fixed on the spline card of joint piece, and joint piece links to each other with saddle pipe.

The piston rod that the utility model has the advantages that the band piston is loaded in the saddle pipe of bicycle, and the double air cylinder body of doing of saddle pipe only need be pulled out telescopic handle during use, can inflate, and in the time of by bike it is put down, and neither influence can not lost by bike yet.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 is a structural representation of the present utility model.

An aperture is opened in the lower end of bicycle saddle pipe 1, the induction opening of high pressure tank 7 is docked with it, the loam cake mouth of high pressure tank 7 connects air hose 8, the valve inside clip of air hose 8 is fixed on the saddle pipe with spring clip, in 1 li insertion of saddle pipe by greatly, the piston rod 2 that the steel pipe of little two screw thread sockets is formed, vehicle seat is installed in the big steel pipe upper end, little steel pipe lower end links to each other with piston 3, saddle pipe 1 upper end is with a joint piece 10, joint piece 10 1 ends be provided with outstanding spline card 10 ', be fixed with a spline joint piece 9 on the saddle pipe 1 of its below, with the spline card 10 ' correspondence position of top joint piece 10 offer a spline bayonet socket 9 ', spline card 10 ' under the inflator off working state, snap in when vehicle seat sets back spline bayonet socket 9 ', thereby realize making the purpose of piston rod 2 splines.On spline joint piece 9, be fixed with side link 5, side link 5 other ends and telescopic handle bar 4 are rotatably connected, joint piece 10 links to each other with saddle pipe 1, its spline card 10 ' on be fixed with connecting rod 6, connecting rod 6 other ends contract 4 rotatable linking to each other of formula handle bar with individual, only need during work under spring clip, to take off air hose 8, after bicycle valve core docks.Pull out telescopic handle to the longest, then swing up and down handle, move up and down in saddle pipe 1 by connecting rod mechanism drive piston rod 2 and piston 3, thereby reach the inflation purpose.
