Description
The utility model relates to a kind of inflation pump of vehicle tyre, the miniature inflation pump of especially a kind of bicycle automatic voltage regulation.
At present, relevant inflating tyres of vehicles pump is bike tire's inflation pump of a great variety especially, the main design philosophy of all kinds of inflation pumps and embodiment mostly are to be based upon to exempt on the artificial manual gas filed basis, have reached joint power time-saving effect in practice preferably.But, because the structural design scheme of most of inflation pumps is to occur with split type form, cause poor sealing performance, air pressure low thus easily, and structure was both complicated, installing/dismounting is problem such as inconvenience again.
The purpose of this utility model is to provide a kind of bicycle automatic voltage regulation miniature inflation pump, and it is not only simple in structure, good airproof performance, easy accessibility, and inflation presses highly, improves on the basis that does not change existing car wheel structure and the perfect function of general inflation pump.
The purpose of this utility model is achieved in that the miniature inflation pump of a kind of bicycle automatic voltage regulation, and it comprises the camhousing (1) that has oil hole on it, big piston (2), cylinder has 4 tightening screw lower covers (3), taper valve piston (4), orienting sleeve (5), gland (6), turriform spring (7), air gate (8), reverse needle (9), the circular pump housing (10), gas-tpe fitting (11), hollow tubular (12), regulator hole (13), air extractor vent (14), pressure regulating valve (15), pressure regulation cap (16), locknut (17), hollow guiding bar (18), O-ring seal (19), dowel hole (20), steel ball (21), ball hole (22), axle (23), cam (24), pressure spring (25), retracing spring (26) and circular lower cover (27); It is characterized in that the described pump housing (10) by 4 tightening screws on the lower cover of air cylinder (3) and have the lower cover (27) of orienting sleeve (5) in it, the camhousing (1) that has oil hole on it is fixedly attached is an integral body, its unidirectional needle of Inner Front End place screw thread attaching (9) of the described pump housing (10); The front end place screw thread attaching gas-tpe fitting (11) of its interior unidirectional needle of attaching (9) of the described pump housing (10); Its preceding upper end of the described pump housing (10) has the pressure regulation cap (16) of O-ring seal, pressure regulating valve (15), pressure spring (25) successively by locknut (17) attaching; The equipped end of its interior side pressure along horizon direction and close pressure regulating valve (15) of the described pump housing (10) has the hollow guiding bar (18) of air extractor vent (14); Its interior side screw thread attaching gland (6) of described big piston (2) along horizon direction and close hollow guiding bar (18); One end of described gland (6) is attaching retracing spring (26), taper valve piston (4), steel ball (21) successively, and the conehead of taper valve piston (4) points to steel ball (21).When the pressure in the bike tyre is lower than 0.28 to 0.42Mpa, because camhousing has replaced the axle skin of the front axle of car or rear axle and has been fixed together with floral disc on the bicycle, the interior axle of camhousing this moment is gone up a fixing cam motion relative with big piston makes gas compression, when big piston and cam are in that the dead point is subjected to the pressure of turriform spring and this moment gas after compression of resetting enters gas-tpe fitting through air gate by reverse needle and forms air chamber, the interior pressure of the pressure that makes it its air chamber and tire equates.When the pressure of bike tyre is higher than 0.28-0.42Mpa, air-flow enters regulator hole and pressure regulating valve is pushed to an end of pressure regulation cap through gas-tpe fitting in the tire, air-flow entered the hollow guiding bar and again the taper valve piston was pushed simultaneously to direction towards steel ball along air extractor vent this moment, and continue to promote steel ball again and be in non-contacting state up to big piston and cam, when if the pressure in the bike tyre continues decline and is lower than 0.42Mpa, pressure regulating valve is subjected to the pressure of pressure spring and resets, valve piston is also resetted by the pressure of retracing spring, steel ball can be got back in the big piston again, big piston is promptly worked, and so circulation can guarantee that tire remains between the 70%-100% of settling pressure.
Owing to adopted the scheme that the pump housing and lower cover, camhousing is fixedly connected with screw, thereby make integral structure of the present utility model very simple, and can be voluntarily to the gas that charges and discharge of tire, thereby keep the wheel pressure of bicycle to be in best running condition.
