Abstract
The utility model relates to the technical field of automobile maintenance in particular to a tire inflation device whose inner is hidden with a barometer, the tire inflation device is convenient to use and has a good seal performance. The utility model is realized as the following technical scheme: the pressure spring, the spring supporting frame and the calibration meter are sealed in one casing, the end face of one side of the casing is provided with an air inlet, the center of the casing is provided with a reading window, when the air with a certain pressure gets into the casing from the air inlet of the casing, the air pushes the calibration meter to overcome the elastic resistance of the pressure spring and move, according to the compression length of the pressure spring, that is the moving distance of the calibration meter, the air pressure can be knew.
Description
The utility model relates to the instrument of vehicle maintenance and repair field, refers in particular to a kind of easy to use and robust Tire Inflation System.
Current, along with expanding economy, automobile has been inseparable with people's life, for M R automobile better, people wish to have some convenient, easy-to-use instrument of vehicle maintenance and repair, as the air-pressure gauge on the gas filled device, as the common tool of automobile maintenance industry, in vehicle maintenance and repair,, brought into play bigger effect for people's detection wheel tire internal gas pressure size provides a lot of convenience.But in use, people also find its some shortcomings part gradually.Existing compression indicator mostly is arranged on the outside of gas filled device, is easy to be subjected to the damage of artificial or external force.What the air-pressure gauge that has again adopted is such mode: graduation apparatus is made shapes such as triangular prism or quadrangular, its not calibrated end is inserted in of pressure spring, and the other end of pressure spring is set on the piston rod, piston end face links to each other with induction opening, but graduation apparatus, pressure spring, piston is in the general body that is placed on gas filled device, the outside end face of body does not seal, when the admission port feeding has the gas of certain pressure, the pressure of gas promotes the elastic resistance motion that piston overcomes pressure spring, the graduation apparatus that is fastened on pressure spring stretches out outside the body of gas filled device, expose to the outer length of body according to graduation apparatus like this, promptly know the pressure of gas.But this air-pressure gauge device also has its tangible weak point, one: graduation apparatus, pressure spring, piston not with the body sealing of gas filled device, be unfavorable for preventing dust, protection against the tide.Two: this air-pressure gauge device is to promote the external indication air pressure of the body size that graduation apparatus stretches out gas filled device by air pressure, and this both little safety also damages graduation apparatus easily.Also damage graduation apparatus easily.
The purpose of this utility model just is to provide a kind of easy to use and robust built-in air pressure tabular form Tire Inflation System.
The utility model is achieved by the following technical solution: gas filled device, pressure spring, end cap, spring supporting frame, graduation apparatus, sleeve pipe.One of pressure spring is arranged in the blind hole of graduation apparatus, one headgear is located on the spring supporting frame, pressure spring, spring supporting frame, graduation apparatus all is encapsulated in the columniform sleeve pipe, end cap is plugged in an end of sleeve pipe, one induction opening is arranged on the other end of sleeve pipe, sleeve pipe is encapsulated in again in the body of gas filled device, upside end face at the sleeve pipe middle part, offer a reading window, on the periphery at sleeve pipe middle part,, a groove that goes in ring is arranged corresponding to the position of reading window, hoop is provided with a pointer ring in the groove, in addition, in the position of the body of gas filled device middle part, a display window is arranged corresponding to the reading window of sleeve pipe.
The utility model is simple in structure, easy to use, good airproof performance, not fragile.
Below in conjunction with accompanying drawing the utility model is described further
Accompanying drawing 1 is the utility model front view
Accompanying drawing 2 is the utility model sleeve portion front view
Accompanying drawing 3 is the utility model sleeve portion cutaway view
See accompanying drawing 1,2,3, the utility model comprises: gas filled device 1, pressure spring 2, end cap 3, spring supporting frame 4, graduation apparatus 5, sleeve pipe 6, one of pressure spring 2 is arranged in the blind hole 51 of graduation apparatus 5, one headgear is located on the spring supporting frame 4, pressure spring 2, spring supporting frame 4, graduation apparatus 5 all is encapsulated in the columniform sleeve pipe 6, end cap 3 is plugged in an end of sleeve pipe 6, one induction opening 61 is arranged on the other end of sleeve pipe 6, sleeve pipe 6 is encapsulated in again in the body 11 of gas filled device 1, upside end face at sleeve pipe 6 middle parts, offer a groove 63 that goes in ring, hoop is provided with a pointer ring 64 in the groove 63, in addition, corresponding to the position of the reading window 62 of sleeve pipe 6, a display window 12 is arranged at body 11 middle parts of gas filled device 1; The pointer ring 64 at sleeve pipe 6 middle parts also can adopt at sleeve pipe 6 middle parts a glass or other transparency material are installed, and the mode that carves a cursor line then thereon replaces.
When using the utility model, at first make the blind hole 51 of graduation apparatus 5 outwards graduation apparatus be filled in the sleeve pipe 6, afterwards, spring supporting frame 4 and sheathed thereon pressure spring 2 are filled in sleeve pipe 6, and the free end of pressure spring 2 is withstood on the inner side end of blind hole 51 of graduation apparatus 5.After using 1 pair of tire of gas filled device or other thing to be charged to a certain degree, as wonder the atmospheric pressure value that is inflated in the object, only need the air inlet switch of gas filled device 1 cuts out, reason owing to draught head, the air that is inflated in the object must pour in down a chimney in gas filled device, after the air that pours in down a chimney enters the admission port 61 of sleeve pipe 6 from the appendix 13 of gas filled device 1 through body 11, the elastic resistance that promotion graduation apparatus 5 overcomes pressure spring 2 travels forward, and the reduction length of pressure spring 2 and air pressure size have definite relation, so miles of relative movement according to graduation apparatus 4, just the reduction length of pressure spring 2 can be read the numerical value that is inflated the object internal gas pressure from the pointer ring.
