Abstract
The utility model relates to an alarming device for tyre leakage, which comprises an inflating valve seat whose the lower end is provided with a connecting structure. A pressure regulating member with an alarming whistle is arranged out of the inflating valve seat, and the inflating valve seat and the pressure regulating member are all hollow structures. The inflating valve seat is provided with an air valve by an air valve seat, and the air valve extends into the pressure regulating member, and a spring is arranged between the air valve and the pressure regulating member. The utility model overcomes the defects that the existing alarming device has complicated structure and inconvenient installation. The utility model has the advantages of high sensitivity and low failure rate, and is suitable for motor vehicles to use.
Description
The utility model relates to tire air-leaking alarming device.
Existing tyre flat alarm device is many reports to the police by the deformation that takes place behind the tire flat.Its structure is relatively complicated, and inconvenience is installed, and sensitivity is low, and fault rate is higher.
The purpose of this utility model is to provide a kind of simple in structure, easy for installation, highly sensitive tyre flat alarm device.
A kind of tyre flat alarm device, comprise a valve spud, the valve spud lower end is provided with connection structure, the pressure regulation part at the valve spud peripheral hardware one band warning whistle, above-mentioned valve spud and pressure regulation part are hollow structure, above-mentioned valve spud is established a valve valve by valve seat insert, and above-mentioned valve valve upper end is stretched between the hollow structure of above-mentioned pressure regulation part and the two and is provided with spring.
Above-mentioned leak alarm, valve spud, pressure regulation part are circular tube structure, and the connection structure of valve spud lower end is the silk mouth.
Above-mentioned leak alarm, valve seat insert are a disk or an end osed top pipe, establish a column valve valve in the air extractor vent of above-mentioned valve seat insert, and above-mentioned air extractor vent place is provided with seal ring.
Above-mentioned leak alarm, their end diameters of valve spud and pressure regulation part be less than the other end, and the two is by the bigger end phase limit of diameter, and be that silk mouthful connects.
Above-mentioned leak alarm, valve spud, the vertical section of pressure regulation part is
Shape.
Above-mentioned leak alarm, valve seat insert are located at the bigger end of valve spud diameter, and the less end of diameter is provided with outside thread and seal ring.
Above-mentioned leak alarm, the warning whistle are located at the diameter of pressure regulation part than small end.
The utility model is made up of the pressure regulation part at valve spud, valve seat insert, valve valve, seal ring, spring and the band warning whistle.Its used parts are few, simple in structure, and cost is low, and fault is few.During use, tyre valve core is pulled out, then this annunciator is screwed into tire tube valve, regulate the pressure regulation part and make air pressure balance.The whole operation process is very easy.When tire lost heart to certain air pressure, the valve valve was opened, and the warning whistle pipes, and is highly sensitive.Being suitable for power actuated vehicle uses.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the cutaway view of present embodiment.
With reference to Fig. 1, present embodiment comprises that the vertical section shows
The valve spud 6 of shape and pressure regulation part 2, the two links to each other by the bigger end of diameter, and is silk mouthful connection; The less end of pressure regulation part diameter is provided with the warning whistle 1, be provided with an end osed top tubulose valve seat insert 5 in the bigger end of valve spud diameter, establish a column valve valve 4 in the air extractor vent on the valve seat insert, the air extractor vent place is provided with seal ring, valve valve upper end is stretched in the pressure regulation part and between the two and is provided with spring 3, and the valve spud diameter is provided with seal ring 7 and outside thread than small end.
