Abstract
The utility model relates to a portable bicycle air pump. The portable bicycle air pump is characterized in that both ends of a cylinder body are sealed; a fixing plug with an air inlet one-way valve and an air outlet one-way valve is arranged in a cylinder; an air inlet and an exhaust port are both arranged on the upper part of a side wall of the cylinder body; an air inlet pipeline is communicated with an air way of the air inlet one-way valve built in the fixing plug; a traction fiber with a handle is arranged in the air inlet pipeline and is connected with a piston; the cylinder body is arranged in a standing pipe of a bicycle; a saddle is fixed on the cylinder body. The utility model has the advantages that the portable bicycle air pump can be used for replacing an ampere pipe, the saddle does not need to be moved away when inflating tyres, the extreme higher position of the handle is under the saddle, the portable bicycle air pump is convenient to operate and carry, etc.
Description
A kind of portable bicycle pump belongs to automobile-used instrument.
Existing a kind ofly be loaded in the standpipe of bicycle with car portable type pump, its structure be still for to promote piston downwards by handle, the gas of piston base is pressed into tire realizes inflating.The deficiency of the pump of this structure is, need move the peace seat when using inflator, and the position of handle is too high, makes troubles to use.
The purpose of this utility model is to provide in a kind of standpipe that is loaded on bicycle, and the peace seat is fixed on the air cylinder, uses and carry all portable bicycle pump easily.
The purpose of this utility model is realized by following technological scheme: a kind of portable bicycle pump, in the standpipe (19) of bicycle, be equipped with by air cylinder (1), piston (11) is set in air cylinder (1), outlet pipe (7) is set on the sidewall of air cylinder (1), its special way is, the closed at both ends of air cylinder (1), in air cylinder (1), settle and have air inlet and exhaust check valve (9,17) fixedly plug (8), on air cylinder (1), be fixed with suction tude (2), the front end of suction tude (2) is contained in the fixing plug (8), and traction fiber (4) is loaded in the suction tude (2), and connect to form with piston (11).
Air inlet that fixing plug (8) is built-in and exhaust check valve (9,17) are provided with valve seat (15) by valve body (16) in valve body (16), valve seat (15) contacts with steel ball (18), and the front end of steel ball (18) is provided with banking stop (14) and forms.
One end of traction fiber (4) is connected with handle (15).
Portable bicycle pump of the present utility model is compared with car portable type pump with existing, because the traction fiber of pump of the present utility model pulling piston is to draw the suction tude on being fixed on the air cylinder sidewall; Pump places standpipe, and air cylinder replaces the peace pipe to fix the peace seat, needn't move the peace seat when inflating, and the extreme higher position of handle has and uses and carry advantages such as all convenient under the peace seat.
The utility model is described in further detail to utilize an embodiment shown in the drawings below.
Fig. 1 is a portable bicycle inflator structure cross-sectional schematic.
Fig. 2 is the schematic representation that the utility model is connected with bicycle.
With reference to Fig. 1, air cylinder (1) is two joint steel cylinders, is integral with being threaded, and suction tude (2) is welded on the sidewall of going up joint of air cylinder (1), the head end of last solar term cylindrical shell (1) is a closed shape, and the outlet pipe (7) that has relief opening (6) is threaded with the joint of going up of air cylinder (1).
Fixing plug (8) is made of rubber, in fixing plug (8), settle respectively by valve body (16), be provided with valve seat (15) in valve body (16), valve seat (15) contacts with steel ball (18), and the front end of steel ball (18) is provided with breather check valve (9) and the exhaust check valve (17) that banking stop (14) is formed.Valve body (16) is made of metallic material.Valve seat (15) is made of rubber.Banking stop (14) is made of metallic material.The fixedly plug (8) that air inlet and exhaust check valve (9,17) will be set is contained in two joint junctions of air cylinder (1), and the front end of suction tude (2) is contained in the fixing plug (8), and suction tude (2) is communicated with breather check valve (9) gas circuit.
Piston (11) is made of rubber.Leather cup (10) and bearing ring (12) are respectively put in the two ends of piston (11), one end of traction fiber (4) is threaded with handle (5), the other end penetrates the suction tude (2) from the suction port (3) of suction tude (2), make traction fiber (4) and piston (11) with nut, leather cup (10) and bearing ring (12) are connected and fixed.Following joint with air cylinder (1) is threaded with last joint again.Stop up the head that (13) are pressed into joint under the air cylinder (1).
During use, outlet pipe (7) is connected with tyre valve, with pulling handle (5), traction fiber (4) pulling piston (11) moves upward, and the gas of piston (11) epicoele is opened exhaust check valve (17) makes the gas of piston (11) epicoele and the gas of fixing plug (8) epicoele be pressed into tyre inflation by relief opening (6), outlet pipe (7) together.Negative pressure by piston (11) cavity of resorption moves downward piston, and air is opened breather check valve (9) from suction port (3), suction tude (2), makes gas enter into the epicoele of piston (11), thereby makes piston (8) to-and-fro motion realize tyre inflation.
Inflation finishes, and outlet pipe (7) is coiled in the space that places below the peace seat, and handle (5) is stuck in and gets final product below the peace seat.
Claims (3)
1, a kind of portable bicycle pump, in the standpipe (19) of bicycle, be equipped with by air cylinder (1), piston (11) is set in air cylinder (1), outlet pipe (7) is set on air cylinder (1), it is characterized in that: the closed at both ends of air cylinder (1), in air cylinder (1), settle fixedly plug (8) with air inlet and exhaust check valve (9,17), on the sidewall of air cylinder (1), be fixed with suction tude (2), the front end of suction tude (2) is contained in the fixing plug (8), and traction fiber (4) is loaded in the suction tude (2) and with piston (11) and connects to form.
