Description

Digital display tire pressure inflatable gun

The present invention relates to a tire inflation gun, especially an index tube showing a tire pressure inflation gun

According to the tire, the tire is an important part of the vehicle's travel, and the tire pressure value is often inseparable from the driving safety. Generally, if the tire pressure value is too high, the middle part of the tread will protrude and it will not be in full contact with the ground. Although the engine load on the vehicle is light, it may be dangerous because of the high load of the tire itself and the possibility of a flat tire;

If the tire pressure value is too low, the running resistance will become larger, and the engine will have a relatively large load. When the contact area with the ground becomes larger, the durability and the tread life of the tire will be shortened, and when the tire rolls, the tire will be worn. The wall also tends to increase the internal temperature due to the large deflection, and there is a risk of puncture when subjected to relatively large impact or high-speed driving;

Therefore, the manufacturer has developed a variety of tire pressure air guns, as shown in Figure 7, the tire pressure air gun 9, in order to be inflated while the tire tire pressure measurement, and then adjusted The tire pressure is most suitable for driving safety; that is, the user presses the trigger 92 and the handle 91 against the tire while holding the tire with one hand, while watching the pressure displayed by the air pressure gauge 93, the tire is usually inflated to an overpressure state, and then A pressure relief valve 94 provided in the tire pressure air gun 9 is depressurized to an appropriate tire pressure state. The pressure relief valve 94 operates the pressure relief valve 93 in a pressing manner, as shown in Fig. 8.

Therefore, the main purpose of the present invention is to provide a digital display tire pressure inflation gun which is easy to handle pressure relief with one hand; the second objective of the present invention is to provide a digital display tire pressure inflation which is easy to handle with one hand and is not easy to slip. gun.

The gun body of the present invention is provided with a grip rubber sleeve provided by the user, which is convenient for the user to hold the hand with one hand, and it is not easy to slide the new air gun down, and the operation is enhanced.

First, referring to Figures 1 to 4, the present invention relates to a digital display tire pressure inflatable gun A, which includes:

A gun body 1 , as shown in FIG. 1 and FIG. 2 , is also provided with a first-class road 11 , and the flow channel 11 forms an inlet 12 and an outlet 13 outside the gun body 1 , and is also in the middle of the flow channel 11 . A relay flow path 14 is disposed, and a primary flow path 15 is extended from the rear end of the flow path 11; further, the flow path 11 further includes an upper flow path 111 and a lower flow path 112, and the relay flow path is further included. 14 is vertically connected between the upper flow path 111 and the lower flow path 112. Further, the gun body 1 is provided with a grip rubber sleeve 6 corresponding to the grip of the user.

A digital pressure gauge 2, as shown in FIG. 1 and FIG. 2, is mounted on the gun body 1 and communicates with the secondary flow passage 15, and the outside of the digital pressure gauge 2 is sleeved with a cast outer casing 21.

As shown in FIG. 2 and FIG. 4, a plurality of valve bodies 3 are installed in the relay passage 14 to control the opening and closing or deflation of the flow passage 11, and the multi-stage valve body 3 is further The utility model comprises an elastic body 32, a class rod 31 and a first leakage preventing washer 33, a second leakage preventing washer 34, and one end of the class rod 31 is exposed to the gun body 1, and the class rod 31 and the foregoing A flow passage 16 is formed in the flow passage 14; further, the first leak stop washer 33 and the second leak stop washer 34 are disposed on both sides of the middle portion of the class rod 31, and the first leak stop washer 33 is adjacent to The relay flow path 14 of the upper flow path 111 moves, and the second leakage preventing washer 34 moves adjacent to the relay flow path 14 of the lower flow path 112; and the class rod 31 is provided with at least one pressure relief groove 311. In the present embodiment, two opposing pressure relief grooves 311 are provided, and when the pressure relief groove 311 is located in the relay flow path 14, the air leakage passage 16 is formed (as shown in FIG. 6).

a trigger lever 4, as shown in FIG. 1 and FIG. 2, is pivotally disposed on the gun body 1, and the inner side of the trigger lever 4 abuts against one end of the class lever 31 for providing control of the class lever 31 relative to the middle Following the position of the flow channel 14.

A barrel 5 is shown in FIGS. 1 and 2, and the barrel 5 is connected to the outlet 13 of the gun body 1.

The above-mentioned components constitute the digital display tire pressure inflation gun A. As shown in FIG. 4, the present invention must first connect its inlet 12 to the air pressure source, and the high pressure air enters the flow passage 11 upward. The track 111, however, the multi-stage valve body 3 of the relay flow path 14 has the elastic force of the elastic body 32 pushing against the class rod 31 to stop the high-pressure gas with the first leak-proof gasket 33 and the second leak-proof gasket 34. In the upper flow channel 111.

When the tire is to be inflated, the front end of the barrel 5 is disposed on the air nozzle of the tire, and then the one hand is held by the gripping rubber sleeve 6 of the gun body 1 and the trigger rod 4 is gripped. Bottom, that is, the trigger lever 4 is close to the grip rubber sleeve 6, the trigger lever 4 will interlock the sliding of the multi-stage valve body 3 with respect to the relay flow passage 14, as shown in FIG. The flow path 14 is opened, and the upper flow path 111 and the lower flow path 112 are electrically connected between the upper flow path 111 and the lower flow path 112, and the high-pressure gas located in the upper flow path 111 flows through the relay flow path 14 and the lower flow path 112. Guided by the tube 5, the high pressure gas will eventually flow into the tire.

When the tire pressure inflator A of the present invention is used, the user can inflate the tire while viewing the digital pressure gauge 2, so when the tire is overcharged with high pressure gas, the tire is overpressured. The trigger lever 4 can be slightly relaxed, as shown in FIG. 6, but the trigger lever 4 is not completely relaxed. In other words, the multi-stage valve body 3 will slightly slide downward, so that the overpressure gas of the tire will pass through the lower flow passage 112 and relay. The flow passage 14 flows out through the air discharge passage 16 formed by the air venting groove 311 until the tire tire pressure is appropriate, and the trigger lever 4 is completely relaxed. At this time, the original state is restored, that is, the multi-stage valve body 3 is closed in degree. The relay flow path 14 is as shown in FIG. In particular, the high pressure gas of the upper flow path 111 also flows out through the relay flow path 14 and the pressure relief flow path 14.

In summary, the present invention relates to a digital display tire pressure inflation gun, which can move the multi-stage valve body relative to the inside of the relay flow channel by one-hand operation of the trigger lever, thereby opening and closing the flow in a multi-stage manner. The road and the pressure relief, and the digital pressure gauge, in order to facilitate the inflation and overpressure of the tire, the operability is good; the structure of each embodiment has not been seen in the publications or public use, in line with the patent application requirements, please 钧Bureau Mingjian, granting patents as soon as possible, and praying for it;
