Abstract
The utility model discloses a gas pump, more specifically, an automatic gas pump of a bicycle. The utility model is characterized in that the gas pump comprises a gas cylinder, a piston, a crank connecting bar mechanism, a clutch and a driving gear wheel pair; wherein, the gas cylinder is matched with the gas inflating valve of the bicycle tyre and then are jointly arranged on the bicycle tire; the driving gear wheel pair is arranged on the wheel axle of the bicycle tire. The gas pump has reasonable design and simple structure. When in use, the bicycle structure need not to be changed, and thus the installation and maintenance as well as application are convenient. The gas is filled into the bicycle tyre when the bicycle is running, realizing the automation of the gas filling operation of the bicycle.
Description
The utility model relates to a kind of Floor Pump, exactly is the bicycle automatical air pump.
When bike tire's air pressure is not enough, has to stop and inflate, the hand of both having made dirty has delayed the time again.Woman and juvenile student by bike is in the majority now, and strength was not enough when these people inflated; These unfavorable factors are given and are brought a lot of inconvenience by bike.Another kind of situation is, can not in time inflate to bicycle, and bike tire is moved under the situation of air pressure deficiency for a long time, causes the improper damage of tire.
The purpose of this utility model is: a kind of novel Floor Pump that can inflate to bike tyre automatically is provided.
Its goal of the invention is to realize like this.
The bicycle automatical air pump, comprise inflator, piston and crank connecting link, it is characterized in that: inflator is set up on the bicycle spoke floral disc by propping up, piston is positioned at inflator, what link to each other with piston is connecting rod and crank, and crank is located at support top by axle and axle sleeve, and the other end of crank shaft is provided with power-transfer clutch, the power-transfer clutch outside is provided with epicyclic wheel by axle, is located on the bicycle shaft with epicyclic wheel ingear idle pulley.
The utility model is reasonable in design, simple in structure; Do not need to change the structure of bicycle during use, can be installed in easily on the bicycle, in the time of need inflating, the rotation of wheel drives the inflation of piston crank mechanism work realization to tire, its use, easy to maintenance; Realized the gas filed automation of bike tire.
Fig. 1 is the utility model structural representation.
The utility model is further described below by embodiment.
As seen from Figure 1, this device comprises inflator, piston, piston crank mechanism, power-transfer clutch and gear pair.Inflator 9 and axle sleeve 5 are installed on the bicycle spoke floral disc 11 by support 10, and the air extractor duct of inflator 9 cooperates with the tire tube valve of tire.Piston 8 is positioned at inflator 9, and constitute piston crank mechanism by connecting rod 7 and crank connecting link, crank shaft is installed in the axle sleeve 5, and power-transfer clutch 4 is installed on the other end of crank shaft, power-transfer clutch 4 outsides epicyclic wheel 3 by axle mounting, are installed on the bicycle shaft 1 with epicyclic wheel 3 ingear idle pulleys 2.
When bike tire need inflate, power-transfer clutch 4 is engaged, whole Floor Pump assembly rotates with the rotation of cycle wheel, and because of idle pulley 2 is fixedly mounted on the wheel shaft 1, this just forces epicyclic wheel 3 around idle pulley 2 revolution, and simultaneously, epicyclic wheel 3 is also carried out rotation; At this moment, crank shaft drives piston crank mechanism and makes piston 8 up-and-down movement inflator 9 in, when piston 8 is descending, the gases in the inflator 9 is pressed into tire by the tire tube valve on the tire, and realization is to the inflation of tire.
After tire pumps enough air in, power-transfer clutch 4 is pushed aside, at this moment crank connects mechanism and epicyclic wheel 3 disengages, epicyclic wheel 3 idle running, the piston crank mechanism stop motion, piston also stops to Tyre inflating.
