Description
Technical field
The utility model relates to a kind of device of giving automobile tyre inflation, especially a kind of automobile tyre inflation device that can show air pressure numerical value in gas replenishment process.
Background technology
When the interior pressure of motor tire is not enough, cause the automobile sideslip easily; And when interior pressure is excessive, causes easily again and blow out.The generation of many traffic accidents is all owing to pressing not enough in the tire or blowing out and cause.So, what it is suitable to fill when giving automobile tyre inflation? generally be sensation and the experience with the people, this just makes the interior pressure deficiency or the interior pressure of motor tire excessive unavoidably.Although give the device kind of automobile tyre inflation a lot of in the prior art, also do not have a kind ofly can in gas replenishment process, demonstrate the automobile tyre inflation device of pressing numerical value in the motor tire and can control suction quantity in the numeric display mode.
The utility model content
The purpose of this utility model is to propose a kind of automobile tire inflation gun, and when giving automobile tyre inflation, it not only can demonstrate inner pressure of tire numerical value, and can be according to pressing in the device interior pressure numerical value adjusting tire that upward telltale shows.
The technical scheme that realizes above-mentioned purpose is: automobile tire inflation gun comprises the rifle body 3 that is shaped as pistol, as the trigger 18 of air flue switch with as the gun barrel of gas-adding pipe 1 and the charging connector of gas-adding pipe termination.Main airway 4 is arranged on rifle body inside, and intake interface 16 has a branch airway dypass 41 in the lower end of gun stock at main airway 4 leading portions, is connected with a cover air pressure numerical value sensing display apparatus on this branch airway dypass; In the stage casing of air flue a branch airway dypass 42 is arranged, an aie escape valve 12 has been installed on this branch airway dypass; Gas-filled switch device is arranged on the back segment of main airway 4.
Because the utility model automobile tire inflation gun has a cover air pressure numerical value sensing display apparatus and an aie escape valve on air flue, when giving automobile tyre inflation, inner pressure of tire size just can digitalisation show, and can regulate in the tire easily according to the interior pressure numerical value that telltale shows and press.

Fig. 2 is that main airway and branch airway dypass and corresponding component are provided with scheme drawing among Fig. 1.
Among the figure: 1. gas-adding pipe, 2. tie bolt, 3. rifle body, 4. main airway, 41,42 branch airway dypass, 5. piston, 6. seal ring, 7. liquid crystal digital display window, 8. hold the grid chi, 9. respond to vernier, 10 spacer shells, 11. pressure regulating screws, 12. aie escape valve, 13. moving valves, 14. recover spring, 15. screw, 16. inlet suction ports, 17. push rods, 18. trigger, 19. displacement bars, 20. pressure measurement springs.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and embodiment.
As depicted in figs. 1 and 2, the utility model automobile tire inflation gun is by the air flue in the rifle body 3 that is shaped as pistol, the rifle body and air pressure numerical value sensing display apparatus, gas-filled switch device on the air flue and have parts such as charging connector gas-adding pipe 1, intake interface 16 and form.At main airway 4 leading portions a branch airway dypass 41 is arranged, be connected with a cover air pressure numerical value sensing display apparatus on this branch airway dypass; In the stage casing of air flue a branch airway dypass 42 is arranged, an aie escape valve 12 has been installed on this branch airway dypass; Gas-filled switch device is arranged on the back segment of main airway 4; Pressure regulating screw 11 is connected with the end of numerical value sensing display apparatus, is positioned at the rear end of rifle body 3.
Air pressure numerical value sensing display apparatus is to be made of piston 5, seal ring 6, liquid crystal digital display window 7, appearance grid chi 8, induction vernier 9, circuit card, displacement bar 19, pressure measurement spring 20 part.Piston 5 is positioned at the inlet end of air flue dypass 41, seal ring 6 is enclosed within on the seal groove of outer wall of piston 5, displacement bar 19 is connected the back side of piston 5, pressure measurement spring 20 is enclosed within on the displacement bar 19, the one end withstands on the back side of piston 5, and the other end withstands on the spacer shell 10, and induction vernier 9 is vertically connected on the back segment of displacement bar 19, liquid crystal digital display window 7 and appearance grid chi 8 are arranged side by side in the upper end of rifle body 3, and the end of induction vernier 9 is close to and holds on the grid chi 8.
Gas-filled switch device is by trigger 18, push rod 17, moving valve 13, recovers spring 14, screw 15, connects and composes successively.Moving valve 13 is positioned on the main airway 4.
During inflation, inlet suction port 16 is linked to each other with air pump by air inlet pipe, the charging connector of gas-adding pipe 1 termination is connected with tire, cocking 18, trigger 18 just drives push rod 17 promotion moving valves 13 and moves right, and admission port is opened, and pressurized air enters tire by the main airway in the rifle body 4.After the operator unclamped trigger 18, moving valve 13 was moved to the left under the effect that recovers spring 14, and main airway is cut off by moving valve 13, stopped inflation.In gas replenishment process, pressurized air in the gun barrel moves right by the piston 5 that branch airway dypass 41 promotes in the air pressure numerical value sensing display apparatus, the pressure measurement spring 20 of piston 5 right-hand members is subjected to force compresses, the displacement bar 19 that is connected as a single entity with piston drives the slip on appearance grid chi 8 of induction vernier 9, and produce corresponding signal current, this signal current finally shows the size of inflation pressure this moment through conversion, amplification, demarcation on liquid crystal digital display window 7.And after unclamping trigger 18, what show on the liquid crystal digital display window 7 is the interior pressure of tire, if the pressure in the tire is not enough, but cocking continues inflation; If the pressure in the tire surpasses required value, can unclamp trigger, press the aie escape valve 12 on the branch airway dypass 42, unnecessary gas can be bled off, till the tire internal pressure meets the requirements.
