Abstract
The utility model relates to a mechanical device, particularly a tire leakage alarm sensor which is composed of a body portion, a regulating portion, a dust-proof cover, etc. The utility model which is a cylinder is screwed on the valve of an automobile tire. When the air pressure in the tire is over low, the sensor accurately and reliably sends out signals which are transmitted onto an alarm device to remind a driver to pay attention to. The utility model has the advantages of simple structure, convenient installation and operation, reliable performance, low cost, etc.
Description
The utility model relates to a kind of mechanical device, specifically a kind of tire flat warning sensor.
In the prior art, disclose a kind of automobile tyre in the Chinese patent 93224265 and owed the superpressure annunciator, it is characterized in that it has a housing, the housing inner chamber is separated into mutual leak free two parts by rubber gasket, in the movement chamber of upper half-shell, the projector that can launch the superhigh frequency radiowave is housed and owes the superpressure switch, lower part of frame is provided with the supporting piecing devices of tire tube valve, its weak point is that this device is by by radio transmitting apparatus with owe the superpressure switch and carry out sensing, it is big to be affected by the external environment, job insecurity is prone to and fails to report wrong report.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of new technical solution is provided, and it can carry out tire flat warning sensing accurately and reliably.
The technical solution that realizes the utility model purpose is: described tire flat warning sensor is by main body, regulate three parts compositions such as partial sum cover of dust, base portion is by main body, push rod, stage clip, insulated ring, compositions such as circle and conductor wire conduct electricity, the profile of main body is a cylinder, the perforate vertically of its inside, the front end annular distance has negative thread, the terminal outer outside thread that has, negative thread can form to be threaded and cooperate with the outside thread of tyre valve core, the front end of push rod is equipped with the valve top, end is the cone of amplifying gradually, stage clip makes top, valve top to the body front end direction, the conical section of push rod places in the insulated ring of main body, cone is outward the elasticity circle that conducts electricity, and the axial motion of conical section can make the circle that conducts electricity actuate; Adjusting portion is placed in the main body end, by adjusting circle, adjust screw mandrel, adjust spring, adjusting nut and positioning screw cap forms, the top of adjusting screw mandrel is corresponding with the conical section of push rod, adjust between circle and the main body and form detachable the cooperation, adjustment is enclosed the adjustment spring that will adjust the top of screw mandrel and be enclosed within on the bar and is stuck in the main body, on the screw thread of adjusting screw mandrel, be provided with the adjustment nut, and be provided with positioning screw cap, have the gap peep hole that is used to observe push rod and adjusts gap between the screw mandrel on the end of main body, cover of dust has negative thread, can be tightened on the outside thread of main body.
Owing to adopted said structure, make the utlity model has simple in structure, easy to install, dependable performance, low cost and other advantages.
Accompanying drawing is embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model.
1---main body, 2---push rod, 3---stage clip, 4---insulated ring, 5---circle conducts electricity, 6---conductor wire, 7---adjust circle, 8---adjust screw mandrel, 9---adjust spring, 10-gap peep hole, 11---adjusting nut, 12---positioning screw cap, 13---cover of dust, 14---the valve top
Below in conjunction with drawings and Examples essentiality content of the present utility model is described in further detail.
As shown in the figure, the utility model tire flat warning sensor is made up of three parts such as base portion, adjusting partial sum cover of dusts, base portion comprises main body (1), push rod (2), stage clip (3), insulated ring (4), circle (5) and conductor wire (6) composition conduct electricity, main body (1) is a cylindrical shape, perforate vertically in it, the front end of main body (1) has interior spiral shell mosquito, and the outside thread of the size in aperture and the valve inside of tire adapts, and forms the cooperation that is threaded.The front end of push rod (2) is equipped with valve top (14), end is the cone of amplifying gradually, stage clip (3) makes the direction of top, valve top (14) to main body (1) negative thread, the conical section of push rod (2) places in the insulated ring (4) of main body (1), the conical section skin is surrounded by the rubber-like circle (5) that conducts electricity, conical section is when carrying out axial crank motion, and the circle (5) that conducts electricity will actuate thereupon.Adjusting portion is placed in and has in externally threaded main body (1) end, it is by adjusting circle (7), adjust screw mandrel (8), adjust spring (9), adjusting nut (11) and positioning screw cap (12) forms, the top of adjusting screw mandrel (8) is corresponding with the conical section of push rod (2), adjust detachable cooperation of formation between circle (7) and the main body (1), the screw thread that adjustment circle (7) will be adjusted screw mandrel (8) is provided with adjustment nut (11), and be provided with positioning screw cap (12), have the gap peep hole (10) that is used to observe push rod (2) and adjusts gap between the screw mandrel (8) on the end of main body (1), cover of dust (13) has negative thread, can be tightened on the outside thread of main body (1), whole device is inner for being tightly connected.During use, with the valve inside on the normal tire of front end aligning air pressure of main body (1), and screw in gradually, valve top (14) contacts with the valve core bar, and the tension force of stage clip this moment (3) and the air pressure in the tire make valve push up (14) and conflicts mutually with the valve core bar.Observe by gap peep hole (10), and adjust the adjustment nut (11) of regulating part, the end that adjustment screw mandrel (8) is just bumped at push rod (2) gets final product, and screws positioning screw cap (12).When tire flat or air pressure are crossed when low, valve core bar retraction, valve top (14) is to sinciput, thereby make whole push rod (2) top to the valve inside direction, the tapered distal end that push rod (2) amplifies is gradually amplified circle (5) expansion that conducts electricity, the circle (5) that conducts electricity after the expansion makes conductor wire (6) bonding, produces induction, connects warning device and reports to the police.Simultaneously, the warning sensor of hermetically-sealed construction also can stop the gas leakage of valve inside.
