Abstract
The utility model relates to an automatic inflator for a bicycle tyre, comprising a pinion automatic clutch, a pump cavity sensor, a bent shaft pump core pinion mechanism, etc. The pinion drive the inflator to inflate through a rotating shaft, a sensor capsule controls the engagement or the separation of the pinion and a gearwheel through a clutch lever, an adjustment eccentric ring is arranged in a bearing liner, the reliable engagement of the gearwheel and the pinion can be guaranteed when the utility model is installed, and the gearwheel adopts binary separation composite structure to fix the gearwheel at an axle conveniently. The inflation apparatus has the advantages of automatic inflation, automatic pressure limitation, automatic gas stop, convenient installation, convenient use, etc. The utility model can be widely used in various bicycle tyres to have automatic inflation by installing on the bicycle.
Description
The utility model relates to bike tire and inflates technical field automatically.
At present, people are generally adopting traditional manual pump to come to put on the air to bike tire, this common Floor Pump exist volume big, carry shortcoming such as inconvenience, for this reason, someone has developed a kind of automatic inflation air pump, is installed in the axletree place, along with the rotation of wheel, to the bicycle inflation, this inflation pump exists shortcomings such as operation is inconvenient, charge air is less, easy to wear.
Bike tire's snifter that the purpose of this utility model provides a kind of easy to install, inflation automatically, automatically pressure limiting, stops the supple of gas or steam automatically.
The utility model is achieved in that miniature gears self-acting clutch, pump chamber sensor, crank pump core pinion gear mechanism is housed in this snifter, the pump chamber sensor is made up of sensor capsule, sensing lever etc., this sensing lever and clutch lever fork touch, and the clutch lever fork drives clutch fork; In the rotating shaft of crank pump core pinion gear mechanism, be socketed with clutch spindle, drive the power-transfer clutch generation by clutch fork and axially move back and forth, miniature gears is installed, this miniature gears and the big gear wheel engagement that is fixed on the axletree in the end of clutch spindle; During actual the use, wheel, rotate by the large gear turn the small gear, miniature gears makes the air pump pressurized air by crank pump core pinion gear mechanism, tire is put on the air, when bike tire's sufficient gas reaches certain air pressure, sensor capsule expands, and reaching the air pressure of tire equally, the capsule of expansion promotes sensor lever, drives the clutch lever fork, making clutch fork stir the clutch spindle generation moves axially, move axially thereby drive miniature gears, automatic and big gear wheel jump out of mesh stops inflation, when tolerance in the tire is not enough, sensor capsule shrinks, and passes through sensor lever, the clutch lever fork, clutch fork produces axially miniature gears and oppositely moves, mesh with big gear wheel, tire is put on the air, so repeatedly, can be automatically to Tyre inflating or stop inflation automatically.For when this aerator is installed, big gear wheel is contacted with pinion, reliable operation, the adjustment eccentric ring is housed in the aerator bearing shell, rotate eccentric ring during installation, i.e. engagement between scalable big gear wheel and the miniature gears is for ease of installing big gear wheel, big gear wheel is divided into two body unitized constructions, with screw both is connected and fixed at the axletree place during installation.
That compared with the prior art the utility model has is simple in structure, easy for installation, automatic inflatable, advantage such as stop the supple of gas or steam automatically.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 installs and uses the situation scheme drawing for the utility model
Fig. 3 is a pump chamber sensor scheme drawing
Fig. 4 is the self-acting clutch scheme drawing
Fig. 5 is a crank pump core pinion gear mechanism scheme drawing
Referring to accompanying drawing: this snifter by miniature gears self-acting clutch 1 crank pump core pinion gear mechanism 2, sensor lever 3, pump chamber sensor capsule 4, inflated hose 5, adjust eccentric ring 6, bearing shell 7 etc. and form (see figure 1); This snifter 8 is installed on the axletree, and split big gear wheel 9 is installed in a side of axletree, miniature gears 10 and big gear wheel 9 engagement (see figure 2)s; The pump chamber sensor is formed (see figure 3) by sensor capsule 4, sensing lever 3 etc.; The miniature gears self-acting clutch is by clutch lever 11, and clutch is pitched 12 grades and formed (see figure 4); Crank pump core pinion gear mechanism is by crank pump core 13, rotating shaft 14, clutch spindle 15, formations such as anti-rotating pin 16, miniature gears 10, and clutch spindle 15 is socketed in (see figure 5) in the rotating shaft 14; Stir clutch spindle 15 by clutch fork, make miniature gears 10 automatically with big gear wheel 9 engagement or separate, thus the inflation of automatic guidance tire or stop the supple of gas or steam.
Claims (3)
1, a kind of bike tire snifter, big gear wheel, miniature gears, inflated hose etc. are arranged, it is characterized in that, miniature gears self-acting clutch, pump chamber sensor, crank pump core pinion gear mechanism are housed in aerator, the sensing lever of pump chamber sensor and clutch lever fork touch, and are socketed with clutch spindle in the rotating shaft of crank pump core pinion gear mechanism.
