Abstract
The utility model relates to a pressure-regulating inflator which is the improvement of the existing inflator. The lower part of an inflator body is provided with a pressure-regulating valve, a valve core used for opening and closing an air passage is arranged in the regulating valve, and the upper end of the valve core is provided with a spring and regulating screws, wherein, the spring is used for regulating the valve core to bear the maximal air pressure. When the inflation in a tire achieves the needed maximal air pressure, the regulating valve automatically deflates, stops inflating towards the tire, and sends out an alarm sound. The pressure used for inflating towards the tire can be regulated according to the needs. The pressure-regulating inflator has the advantages of simple structure and convenient operation, and relieves the problems that the inflation quantity is judged by that the tire is pressed by hands and the hands are dirtied when the tire is inflated.
Description
The utility model relates to a kind of pump, the pump of particularly a kind of energy pressure regulation.
At present, when people use manual inflator to inflate for tires such as bicycle, tricycle, whether the gas that fills in the tire is into met the requirements of pressure, unsure in the heart, therefore need the tire of delaying unloading that press...withes one's finger frequently, judge the pressure size that charges into gas, not only bother but also easy dirty hand, if beaten many accidentally, riding, it is uncomfortable to jolt, experienced tyre is easy " blowing out " also, lacked if beat, and tire weares and teares easily.
The purpose of this utility model provides a kind of when giving Tyre inflating, when reaching the inflation pressure of giving provisioning request, can the automatic cut-off inflation and send the pressure regulating type pump of alarm sound, and tire is inflated become convenient, and avoided the hand of making dirty.
The purpose of this utility model reaches by following technical measures: on the basis of existing inflator structure, increase a vent hole that is communicated with piston cylinder cylindrical shell bottom, pressure regulator valve is housed on it, it has the valve body of a band through hole, the spool that opens and closes gas circuit is housed in the through hole of valve body, spring is equipped with on the top of spool, and the top of valve hole is by the adjusting screw of scyewed joint band vent, and adjusting screw is withstood spring.By the rotation adjusting screw, can change the pressure of spring to spool, thus can regulate and definite pump in pressure limit, this pressure limit should equate with the pressure of required inflation in the tire.Like this, when Tyre inflating reaches desired pressure, because gas circuit is communicated with, pressure balance, the gas pressure in the pump reaches and gives when deciding the limit, gas jack-up spool, the venting path is opened, and ends to the Tyre inflating process.Finish for user's Tyre inflating of accusing, buzzer is housed, send alarm sound during venting in the upper end of pressure regulator valve.
Advantage of the present utility model: simple in structure, easy to use, when inflating a tire, stop inflation when meeting the requirements of gas pressure, and can send alarm sound, can adjust for the pressure of Tyre inflating, exempted the problem that hand is made dirty.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the buzzer structural representation;
Fig. 3 is the pressure regulator valve structural representation;
See Fig. 1～3, structure of the present utility model is to have done improvement on existing pump basis, bottom at piston cylinder cylindrical shell 1, the vent hole 3 and the inflated hose 4 that are communicated with it are arranged, be screwed pressure regulator valve 2 on the vent hole 3, it is by the valve body 7 of band through hole, metal or nonmetallic garden pearl or pyramidal spool 9, and spring 8 and adjusting screw 6 formed.Valve body 7 through holes have a throat, and spool 9 gets lodged in the throat; Adjusting screw 6 has vent, and it is screwedly mounted on the top of valve body 7 by screw thread, and withstands spring 8, makes spring 8 act on spool 9.Adjust the pressure of 8 pairs of spools 9 of spring by turning adjusting screw 6 up and down.Its pressure size should with inflate the pressure that requires that reaches to tire and equate, could guarantee that like this inflation surpasses when requiring pressure in the tire, the valve 9 of closing gas circuit is backed down by air pressure, realizes that inflation ends.Be fixed with buzzer 5 in the upper end of pressure regulator valve 2, be fixed with reed 10 on it, buzzer 5 can be made with metal or nonmetallic material with reed 10.When pressure regulator valve 2 venting, air-flow blows reed and sends alarm sound.
Claims (3)
1, a kind of pressure regulation pump comprises handle, piston, cylindrical shell, inflated hose, it is characterized in that:
A, be communicated with vent hole in the bottom of cylindrical shell, pressure regulator valve is housed on it, the spool that opens and closes gas circuit is housed in the valve hole of modulating valve, spring is equipped with on the top of spool, the adjusting screw of the top attachment band vent of valve hole, and adjusting screw is withstood spring;
B, buzzer is housed in the upper end of pressure regulator valve.
