Abstract
The utility model relates to an automatic inflating device for tyre used for bicycles, carts, tricycles and motorcycles. The device is mainly composed of a cover, an air filter, a tube, a valve spool, a spring, an adjustable nut, steel balls, a piston and a conical spring and other parts, the device is installed on the tyre in place of the valve inside, once inflated manually, the device can be inflated automatically for a long term and keep the normal pressure within the tyre during driving rotation. The utility model has the advantages of simple device, convenient installation, high reliability, good tightness, long service life, besides, the inflation pressure of the device can be adjusted according to different requirements, and dirt can be kept from dropping inside the product.
Description
The utility model relates to a kind of automatic tyre air inflation device that is used for bicycle, hand barrow, three-wheel vehicle, motor bike etc.
The tire of present various bicycle, hand barrow, three-wheel vehicle, motor bike etc., air pump generally commonly used or Floor Pump inflation have enough air pressure to guarantee tire, improve the service life of tire.But because existing tire tube valve all adopts the rubber valve core, often because of this valve inside is aging, breakage is followed the string, cause the air pressure in the tire to leak, so often manually tonifying Qi, make people feel very inconvenient, especially old man, women feel painstaking.The CN88210101 patent disclosure a kind of " the automatic tonifying Qi valve gear of tire ", can make tire keep normal pressure in the process of moving to the tire automatic supplementary air in the vehicle ' process.But this apparatus structure more complicated, sealing property is relatively poor, and does not have air-filtering arrangement, and dust can directly enter product inside and make motive position accelerated wear test, shortens the service life of product.
The purpose of this utility model is to overcome said apparatus and has defective, and a kind of simple in structure, good seal performance is provided, long service life, and pressure can be regulated as required, can guarantee that vehicle has the automatic tyre air inflation device of normal pressure in the process of moving in the tire.
Task of the present utility model is finished in the following manner: automatic tyre air inflation device is made up of parts such as end cap, cylindrical shell, spring, setting nut, pistons, the cylindrical shell top is provided with the air filtration plug, cylinder chamber top in the cylindrical shell is provided with spring perch, spring and spool, piston is equipped with in the cylindrical shell below, piston head is equipped with valve seat, steel ball and spring, be fixed with cone-shaped spring between the lower end of cylindrical shell and the lower end of piston, insert in the tire inner tube lower end of cylindrical shell, and compress by nut.
When the utility model during as the gas filled device of bicycle, three-wheel vehicle and hand barrow etc., piston bottom end is processed into circular arc.
When the utility model during as the gas filled device of motor cycle tire, the piston lower end installs a cylindrical spring additional and the bottom is the push rod of circular arc.
Spool in the utility model is made by elastomeric material.
After automatic tyre air inflation device of the present utility model replaces tire tube valve to be installed on the tire, only need the manual inflation once after, just can inflate automatically for a long time, make tire keep normal pressure in the process of moving; This apparatus structure is simple, and is easy for installation, uses reliably good seal performance; In addition, the inflation pressure of this device can be regulated as required, and owing to increased air-filtering arrangement, dust can not enter product inside, the long service life of product.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the local structure figure of the utility model embodiment 2.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment 1:
With reference to Fig. 1, the automatic tyre air inflation device that is used for bicycle, hand barrow and three-wheel vehicle mainly is made up of parts such as end cap 1, cylindrical shell 3, spool 4, setting nut 7 and pistons 14.Air filtration plug 2 is equipped with in the top of cylindrical shell 3, spool 4, spring 5 and spring perch 6 are equipped with in the top in cylindrical shell 3 inside cylinder chambeies 10, the piston 14 that the lower end is a circular arc is equipped with in the below of cylinder chamber 10, valve seat 12, steel ball 13 and spring 21 are equipped with in the top of piston 14, be fixed with spring shelves ring 15 and cone-shaped spring 16 between the lower end of the bottom of piston 14 and cylindrical shell 3, the lower end of cylindrical shell 3 is injected in the steel ring 11 and the inner tube of a tyre 17, and compresses with nut 8 and packing ring 9, in addition, setting nut 7 is equipped with in the stage casing of cylindrical shell 3.
Bicycle in the process of moving, when the position that automatic tyre air inflation device is housed contacts with ground, the inner tube of a tyre 17 is crushed out of shape, promote piston 14 to the motion of the top of cylindrical shell 3, the volume of cylinder chamber 10 is reduced, thereby produce pressurized air, this pressurized air is pushed steel ball 13 open and is entered in the inner tube through passage, when in the cylinder chamber 10 with the inner tube of a tyre 17 in air pressure when in a basic balance, owing to the effect of spring resets steel ball 13.When the position built on stilts of automatic tyre air inflation device is housed, because the effect of cone-shaped spring 16 resets piston 14.Piston 14 makes when resetting and produces negative pressure in the cylinder chamber 10, make the outer air of device through hole and air filtration plug 2 on the end cap 1 and push spool 4 open and enter in the cylinder chamber 10, when air pressure in the cylinder chamber 10 and the air pressure outside the device are in a basic balance, because the effect of spring 5 resets spool 4.
The height that automatic tyre air inflation device is pressed from inflation can be regulated as required voluntarily.Control method is: rotation setting nut 7, it is many more that cylindrical shell 3 is stretched out outside steel ring 11, then low more from the inflation pressure, otherwise then press high more from inflation.
Embodiment 2:
With reference to Fig. 1, Fig. 2, the keystone configuration of automatic tyre air inflation device that is used for motor bike is identical with embodiment 1, and its difference is, by straight pin 18 cylindrical spring 19 is housed in the lower end of piston 14 and the bottom is the push rod 20 of circular arc, to increase buffering effect.
Claims (4)
1, a kind of automatic tyre air inflation device, comprise end cap 1, cylindrical shell 3, spring 5, spring perch 6, setting nut 7, cylinder chamber 10, piston 14, it is characterized in that: the top of cylindrical shell 3 is provided with air filtration plug 2, spool 4 is housed on the spring 5, piston 14 is equipped with in the below of cylindrical shell 3, and valve seat 12, steel ball 13 and spring 21 are equipped with in piston 14 tops, is fixed with cone-shaped spring 16 between the lower end of the lower end of cylindrical shell 3 and piston 14, insert in steel ring 11 and the tire inner tube 17 lower end of cylindrical shell 3, and compress by nut 8.
