Abstract
The utility model discloses a portable double tube inflator used for tyre inflation, in particular to bicycle tyre, comprising an outer air pipe and an inner air pipe matched through a sealing ring. The outer air pipe is connected with the inflator head. The inner air pipe is sheathed on the central tube through a movable piston, and an air inlet is arranged on the inner air pipe. One end of the central tube is connected with the inflator head, and the other end is connected to a fixed piston in the inner air pipe provided with a guiding rod and a conducting hole. The distances between the left cavity of the outer air pipe and the movable piston, and the right cavity of the inner air pipe and the fixed piston are reduced; simultaneously, two-way compressed air is produced, and the air flow in the suction nozzle increases by two times; in this way, the inflating effect of increasing aeration quantity and timesaving is realized. The utility model has the advantages of light weight, small volume, simple structure, convenient operation, safety and reliability.
Description
One, technical field
The utility model relates to a kind of tyre inflation instrument, particularly a kind of portable double-barreled pump.
Two, technical background
Miniature or small-sized pump aeration quantity is less in the prior art, and common pump volume is bigger, is not easy to carry.
Three, model utility content
The purpose of this utility model is to provide a kind of portable double-barreled pump, it be easy to carry and aeration quantity bigger.
The purpose of this utility model is achieved in that outer tracheae (3) cooperates by seal ring (11) with interior tracheae (2), and outer tracheae (3) is connected with inflator head (7); Interior tracheae (2) is socketed on the center tube (6) by moving piston (4); Interior tracheae (2) is provided with inlet hole (20); One end of center tube (6) is connected with inflator head (7), and the other end of center tube (6) is connected with fixed piston (8), and places interior tracheae (2), is provided with air-guide rod (13) in the center tube (6), and air-guide rod (13) is provided with air pipe (24); Center tube (6) is provided with via (21) and is communicated with air pipe (24) and chamber (12), an outer tracheae left side.
The utility model is owing to adopt moving piston and fixed piston and center tube conducting structure, realized the two-tube while pressurized air of compression stroke and gives tyre inflation, improved charging efficiency and saved inflationtime; In addition,, also just correspondingly reduced the volume of inflator itself, be easy to carry because efficient improves.The utility model also has advantages such as simple in structure, easy to operate and safe and reliable.
Four, description of drawings
Concrete structure of the present utility model is illustrated by following drawings and Examples.
Fig. 1 is a structural representation of the present utility model, Fig. 1 double as Figure of abstract;
Fig. 2 is a center tube N-N cutaway view Amplified image.
Among the figure: 1, handle; 2, interior tracheae; 3, outer tracheae; 4, moving piston; 5, small sealing ring; 6, center tube; 7, inflator head; 8, fixed piston; 9, middle seal ring; 10, the right chamber of interior tracheae; 11, seal ring; 12, chamber, an outer tracheae left side; 13, air-guide rod; 14, air-guide pore; 15, chamber, an interior tracheae left side; 16, annular air scoop; 17, the right chamber of outer tracheae; 18, charging air inlet; 19, spacer; 20, inlet hole; 21, via; 22, fixed piston inlet hole; 23, moving piston intake hole; 24, air pipe.
Five, specific operation process
In the using process, with pulling active handle (1), moving piston (4) is just near fixed piston (8).The annular air scoop (16) that air is formed by outer tracheae (3) and interior tracheae (2) gap enters the right chamber (17) of outer tracheae, and the moving piston intake hole (23) of a route enters chamber (12), an outer tracheae left side, and another road enters chamber (15), an interior tracheae left side through inlet hole (20); Enter the right chamber (10) of interior tracheae by fixed piston inlet hole (22), finish intake process.When with hand propulsion handle (1), the air in the outer tracheae chamber, a left side (12) is compressed, and pressurized air enters tire through charging air inlet (18).Meanwhile, the air compression in the right chamber of interior tracheae (10) after air-guide pore (14) through air pipe (24) the left chamber (12) of tracheae through via (21) enters outside again, enter in the tire through charging air inlet (18) then.Because chamber (12), an outer tracheae left side, the right chamber of interior tracheae (10) produce two-way pressurized air simultaneously, to making the gas flow in the air inlet nozzle (18) increase about one times, thereby realize increase aeration quantity and timesaving effect.
Claims (1)
1, a kind of portable double-barreled pump, it is made up of outer tracheae (3) and interior tracheae (2), it is characterized in that: outer tracheae (3) cooperates by seal ring (11) with interior tracheae (2), and outer tracheae (3) is connected with inflator head (7); Interior tracheae (2) is socketed on the center tube (6) by moving piston (4), and interior tracheae (2) is provided with inlet hole (20); One end of center tube (6) is connected with inflator head (7), the other end of center tube (6) is connected with fixed piston (8), and place interior tracheae (2), be provided with air-guide rod (13) in the center tube (6), air-guide rod (13) is provided with air pipe (24), and center tube (6) is provided with via (21) and is communicated with air pipe (24) and chamber (12), an outer tracheae left side.
