Abstract
The utility model relates to an auxiliary tool for inflating a tyre, which is particularly suitable for inflating large scale motor vehicle tyres, such as automobile tyres, tractor tyres, etc. The utility model comprises an inflation tube (1), an operating lever (2), and an air inlet tube (3), wherein, one end of the air inlet tube is connected with the inflation tube, and the inner cavity of the air inlet tube is communicated with the inner cavity of the inflation tube; the inner wall of the inflation tube is provided with an air blocking opening (6); the connecting point of the air inlet tube and the inflation tube is positioned between the air blocking opening (6) and an inflation joint (5); one end of the operating lever is provided with a valve core key. The utility model has the advantages of high inflation efficiency, accuracy metering, and convenient and safe operation.
Description
The utility model relates to the accessory appliances that a kind of inflation of tire is used, and is specially adapted to the inflation of a truck conspicuity marking tire such as automobile, trac..
In the prior art, the inflation of truck conspicuity markings such as automobile, a trac. tire, the accessory appliances that is adopted mainly is that inflation is chewed, the inflation that particularly has eave tile is chewed.Utilize inflation to chew the spool in the tire valve is backed down, make gas charge into inside tires from spool.There is following shortcoming in this inflation accessory appliances: one, charge efficiency is low: the air inlet cross section only is 1/4th of spool cross section during inflation, therefore intake air restriction is big, speed is slow, is that 9 00 centimetres inflation of tire reaches 8 air pressure with a diameter, and the motor of 5.5KW needs 10 fens clock times; Two, inconvenient operation, working strength is bigger: in gas replenishment process, need manual operation, the operator must pin inflation with hand and chew, and can not leave all the time, for double rear wheel tire arranged side by side, operation during inflation is more difficult, because the slit is little, inflation is inconvenience very, the operator must squat down on the ground visiting body with hand pin the inflation chew, it is very tired to work; Three, because the operator can not leave, so it can not get safely guaranteeing that this is because in gas replenishment process always, tire has burst apart dangerous and may; Four, the metering of the air pressure in the tire is inaccurate, owing to there is spool to exist between inflation air pump and the inside tires, so actual pressure has error in the shown air pressure size of gas pump meter and the tire, and the tire pressure size can only be leaned on estimation during inflation.
The purpose of this utility model provides a kind of easy to operate inflation of tire accessory appliances, utilizes this accessory appliances can improve charge efficiency effectively.
The purpose of utility model realizes in the following manner.
The inflation of tire accessory appliances, an appendix is arranged, diameter of section is less than control lever and an air inlet pipe of appendix internal diameter, and an end of air inlet pipe is connected with appendix, and the other end is an inlet suction port, the air inlet pipe inner chamber communicates with the appendix inner chamber, one end of appendix is a gas-charging connection, and the appendix inwall is provided with the gas shutoff mouth, and the point of connection of air inlet pipe and appendix is between gas shutoff mouth and gas-charging connection, one end of control lever is provided with the spool key, and the other end is a handle.
The using method of accessory appliances is as follows:
Using method when one, in the tire residual air being arranged.Earlier inlet suction port is connected with the air pump joint before the inflation, gas-charging connection is connected on the valve of tire; Then control lever is inserted from the other end of appendix, and the spool key that makes the control lever end blocks the spool of valve, the rotating operation bar drives valve core rotation, spool is withdrawed from valve, this moment is because the pressure effect of residual air in the tire, make spool be pulled to the position of the gas shutoff mouth in the appendix, the rotating operation bar is fixed on spool in the gas shutoff mouth again; Can start air pump and put on the air this moment, gas enters appendix by air inlet pipe and enters tire by tire valve again, when reaching institute, tire pressure takes, make spool leave the gas shutoff mouth by control lever, and move in the tire valve, utilize control lever that spool is tightened again, at this moment, the gas that comes from air pump passes through the gas shutoff mouth, releases from the other end of appendix; After closing air pump, inlet suction port, gas-charging connection are taken off from air pump and valve.
Two, the using method during no residual air in the tire.Earlier the spool in the tire valve is withdrawed from before the inflation, then spool is put into from the other end of appendix, and utilize control lever that spool is fixed in the gas shutoff mouth in the appendix.Method of operation when other method of operation has residual air with tire is identical.
The inflation of tire that the utility model provides has following advantage with accessory appliances: one, charge efficiency height: because the spool in the valve is removed, increased the air inlet cross section, the air inlet cross section is 100% of spool cross section, therefore it is little to inflate resistance, intake velocity is fast, with a diameter is inflation of tire to 8 air pressure of 900 centimetres, and the motor of 5.5KW only needed get final product in 2.5 minutes; Two, accurate measurement:, make the air pressure of inside tires and the pressure on the compression indicator on the air pump show in full accord owing to removed spool; Three, easy to operate, working strength is low: gas-charging connection need only be connected with tire valve during inflation and get final product, the operator must not push with hand, the manipulation strength when greatly reducing inflation; Four, safe and reliable: after gas-charging connection and tire valve be connected firmly, promptly do not need people's back work, so the people can leave near the tire, personal safety has reliable guarantee.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is a structural representation (mode of operation) of using accessory appliances according to the inflation of tire that the utility model provides, and accompanying drawing 2 is structural representations of control lever in the accompanying drawing 1.
Inflation of tire accessory appliances as shown in drawings, an appendix (1), a diameter of section control lever (2) and the air inlet pipe (3) less than the appendix internal diameter arranged, one end of air inlet pipe is connected with appendix, the other end is inlet suction port (4), the air inlet pipe inner chamber communicates with the appendix inner chamber, one end of appendix is gas-charging connection (5), the appendix inwall is provided with gas shutoff mouth (6), the point of connection of air inlet pipe and appendix is positioned between gas shutoff mouth (6) and the gas-charging connection (5), one end of control lever is provided with spool key (7), and the other end is handle (8).
As shown in Figure 1, the internal diameter of gas shutoff mouth (6) is less than the internal diameter of appendix, the screw thread that has the screw thread with tire valve spool (11) to be complementary on its inwall.In gas replenishment process, spool is fixed in the gas shutoff mouth by screw thread, plays the effect of gas shutoff simultaneously.As shown in Figure 1, gas-charging connection (5) is a sleeve, have on its inwall with tire valve (10) outer wall on the screw thread that is complementary of screw thread.In gas replenishment process, gas-charging connection by screw collar on valve.
As shown in Figure 2, the spool key (7) on the control lever is forked or pincerlike.In when operation, block the end of spool (11) with forked or pincers type key, the rotating operation bar can drive valve core rotation.As shown in Figure 1, set up a supporter (9) between appendix and the air inlet pipe, to improve bonded assembly fastness between appendix and the air inlet pipe.
