Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model anti-gas-leak tire pressure gun embodiment is described further.
See Fig. 1 to 4, a kind of anti-gas-leak tire pressure gun, comprise rifle body and tire pressure table, air inlet pipe 3 and freeing pipe 1 is provided with in described rifle body, control chamber 2 is provided with between described air inlet pipe 3 and freeing pipe 1, described air inlet pipe 3 is communicated to freeing pipe 1 by control chamber 2, closing plate 24 is provided with between described control chamber 2 and air inlet pipe 3, described closing plate 24 is provided with through hole 23, leakproof bar 4 is provided with in described air inlet pipe 3, described leakproof bar 4 one end is provided with the leakage-proof cover 42 matched with described closing plate 24, described leakage-proof cover 42 is provided with the air extractor vent 43 matched with described through hole 23, described leakage-proof cover 42 abuts with described closing plate 24, it is external that the other end of described leakproof bar 4 extends to rifle, the inwall of described air inlet pipe 3 is provided with fixing seal portion, described leakproof bar 4 is fixed in described fixing seal portion, seal described air inlet pipe 3 simultaneously.
When leak air in the control chamber 2 in rifle body phenomenon time, rotate leakproof bar 4, leakage-proof cover 42 on leakproof bar 4 rotates with leakproof bar 4, air extractor vent 43 on leakage-proof cover 42 stops operating when not being communicated with the through hole 23 on closing plate 24 leakproof bar 4, now control chamber 2 is not communicated with air inlet pipe 3, gas in air inlet pipe 3 cannot enter control chamber 2, now can by seeing that the reading of tire pressure table continues to test pressure of tire, inflation is needed then to rotate leakproof bar 4, needs venting, then exitted by aie escape valve 12, it is detachable lower tire pressure gun after tire pressure is normal, again maintain and replace is carried out to tire pressure gun, can not only prevent tire pressure chamber from leaking gas and damage is caused to tire pressure table, tire pressure test can have been continued simultaneously, structure is simple, novel in design, meanwhile, rotate leakproof bar 4 and can also regulate intake velocity, speed is adjustable.
See Fig. 1, tire pressure gun needs when inflating tire to pull trigger 11, pull in the process of trigger 11, rubber ring 22 in control chamber 2 and the inwall generation cliding friction of rifle body, through friction for a long time, rubber ring 22 abrasion deformation, now control chamber 2 can not well completely cut off air inlet pipe 3 and freeing pipe 1, tire pressure gun is caused to leak air phenomenon, make tire pressure gun can not carry out tire pressure test job normally, even may damage tire pressure table, closing plate 24 is provided with between control chamber 2 and air inlet pipe 3, closing plate 24 offers multiple through hole 23, leakproof bar 4 is provided with in air inlet pipe 3, described leakproof bar 4 is provided with leakage-proof cover 42 near closing plate 24 one end, leakage-proof cover 42 is provided with the air extractor vent 43 of quantity corresponding with closing plate 24 and same position, projection 44 is provided with in air inlet pipe 3, projection 44 is fixedly connected with spring 21, the other end of spring 21 is fixedly connected with leakage-proof cover 42, the inwall of air inlet pipe 3 is provided with position-limited trough 5, the inwall of position-limited trough 5 is fixedly connected with spring 21, leakproof bar 4 is provided with limiting stopper 41, the other end of spring 21 is fixedly connected with limiting stopper 41, limiting stopper 41 and position-limited trough 5 clamping.When tire pressure gun does not leak gas, rotate leakproof bar 4 and make the air extractor vent 43 on leakage-proof cover 42 and through hole 23 UNICOM on closing plate 24, when pressing trigger 11, air inlet pipe 3 and freeing pipe 1 conducting, operator can by rotating leakproof bar 4, air extractor vent 43 is changed with the area that is communicated with of through hole 23, thus carrys out intake velocity.
See Fig. 2, when the rubber ring 22 in control chamber 2 because friction causes abrasion deformation repeatedly, lose sealing function originally, air inlet pipe 3 and freeing pipe 1 directly conducting, tire pressure gun leak air phenomenon time, operator only gently need draw leakproof bar 4 to rotate and decontrol, make the air extractor vent 43 of leakage-proof cover 42 and the through hole 23 not conducting of closing plate 24, make air inlet pipe 3 and freeing pipe 1 not conducting, tire pressure meter reading more, determine that tire needs inflation or venting, need inflation, gently turn leakproof bar 4 to inflate, need venting, by aie escape valve 12, gas is released, simple to operate, fast.Limiting stopper 41 and leakage-proof cover 42 are all arranged with rubber ring 22, improve the leak tightness of air inlet pipe 3.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
