Abstract
The utility model provides a trigging signal generator used in tyre pressure warning device, which belongs to a signal generator. A by-pass cylinder(2) is communicated with an upper joint cylinder(3) which is provided with a lower joint cylinder(4); the upper part and the lower part of the upper joint cylinder are respectively provided with a valve core(11) and another valve core(12), and the lower cylinder is provided with a third valve core(15); wherein, the core rods of the another valve core(12) and the third valve core(15) are opposite. Moreover, a mounting plate(7) is arranged between a spring(8) and a core rod(14) on the third valve core, and the mounting plate is provided with a button type switch(6). The trigging signal generator can be used for the assembled single-wheel tire or double-wheel tire, having extensive application range; when the air pressure of the tire is lower than the normal value, the utility model sends out alarm signal, which has high trigging reliability and promises no error alarm as well as preventing the problem that the former triggering signal generator alarms when the air pressure is excessively low and thus damages the tire.
Description
Technical field
The utility model provides a kind of energizing signal generating means, the energizing signal generating means on the annunciator.
Background technology
The annunciator that a kind of tire pressure is arranged now, it is to be used on the tire of single-wheel installation, and its energizing signal generating means is a pair of blade tereminal, and when tire pressure was low, two blade tereminals contacted, and connected warning circuit and sent alerting signal.The problem that this energizing signal generating means exists is can not be used on one group of tire of installing of two-wheel; When on unmade way, travelling, easily produce wrong report; Too big from normal barometric pressure to the pressure reduction the warning air pressure, often when air pressure is very low, just report to the police, easily cause tire failure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energizing signal generating means that is used on the tire pressure remote annunciator, to improve the reliability of signal triggering.
The utility model is to realize like this, be used in the energizing signal generating means on the air pressure remote annunciator, it has the upper connecting barrel body, other extend neck body and upper connecting barrel body are connected together, on the other extend neck body valve connector is arranged, upper connecting barrel body and lower connecting barrel body are installed together, on in the upper connecting barrel body, the bottom is separately installed with valve inside and another valve inside, the third valve heart is installed in the lower connecting barrel body, another valve inside, third valve core bar in the heart is relative, in the spring installation sleeve of lower connecting barrel body bottom spring is installed, between spring and the third valve core bar in the heart adapter plate is arranged, push-button switch is installed on the adapter plate, and the push-button switch top has baffle plate to be fixed on lower connecting barrel body bottom.
Adopt the energizing signal generating means on the tire pressure remote annunciator of being used in of said structure, can be used on the tire that single-wheel or two-wheel install in groups, range of use is wide, when being lower than normal value, sends tire pressure alerting signal, the reliable trigger height, can not report phenomenon by mistake, and just report to the police when having avoided original energizing signal generating means air pressure very low, so that damage the problem of tire.
Description of drawings
Fig. 1 is that the master of the utility model structure looks scheme drawing.Fig. 2 is its cutaway view.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and principle of work.
As shown in drawings, the utility model be used in energizing signal generating means on the tire pressure remote annunciator, it has upper connecting barrel body (3), bypass cylindrical shell (2) is connected together with the upper connecting barrel body, on the other extend neck body valve connector (1) is arranged, upper connecting barrel body and lower connecting barrel body (4) are installed together, on in the upper connecting barrel body, the bottom is separately installed with valve inside (11) and another valve inside (12), the third valve heart (15) is installed in the lower connecting barrel body, another valve inside (12), core bar (13) on the third valve heart (15), core bar (14) is relative, in the spring installation sleeve (10) of lower connecting barrel body bottom spring (8) is installed, between spring and the third valve core bar (14) in the heart adapter plate (7) is arranged, push-button switch (6) is installed on the adapter plate, and the push-button switch top has baffle plate (5) to be fixed on lower connecting barrel body bottom.
During use, this device is installed on the valve of tire, the bypass cylindrical shell is communicated with inside tires by valve connector (1).Push-button switch is connected on the power circuit on the remote annunciator projector.Air pressure in tire just often, core bar (13) on another valve inside (12) presses down third valve core bar (14) in the heart, its downforce is greater than the elastic force of spring (8), push-button switch (6) breaks away from baffle plate (5), be in off state, the power circuit of annunciator projector disconnects, and can not get electric work.When the pressure in the tire is lower than normal value, when being the downforce of core bar (13) less than the elastic force (the big I of this elastic force is determined according to the downforce of core bar under the normal barometric pressure (13)) of spring (8), spring promotes to move on the adapter plate (7), push-button switch with on move, button above it is depressed by baffle plate, make it to be in on-state, the circuit of annunciator projector is switched on, get electric work, send signal, after being installed in annunciator receptor in the operator's compartment and receiving this signal, carry out sound, light is reported to the police.
Push-button switch adopts common form as the push-button switch as the mobile phone button.The valve inside that uses on the structure of valve inside and the present tire is identical.The projector of remote annunciator, the structure of receptor, circuit etc. are the same with projector, receptor on the automobile burglar remote annunciator now commonly used, and only its projector is installed on the tire with this energizing signal generating means.Being installed in a receptor in the operator's compartment can receive and be installed in the alerting signal that a plurality of projectors on a plurality of tires send.
At the external shell of establishing of lower connecting barrel.During inflation, appendix can be connected on the valve inside (11) and finish.
In described spring installation sleeve (10) bottom plus-minus screw (9) is arranged.Turn plus-minus screw and can adjust spring force, the big I of elastic force is determined according to the downforce of core bar under the normal barometric pressure (13).
Rubber cradle (16) is arranged, the leak tightness when using in the valve connector (1) to improve it.
Claims (2)
1, be used in the energizing signal generating means on the tire pressure remote annunciator, it is characterized in that, it has upper connecting barrel body (3), bypass cylindrical shell (2) is connected together with the upper connecting barrel body, on the other extend neck body valve connector (1) is arranged, upper connecting barrel body and lower connecting barrel body (4) are installed together, on in the upper connecting barrel body, the bottom is separately installed with valve inside (11) and another valve inside (12), the third valve heart (15) is installed in the lower connecting barrel body, another valve inside (12), core bar (13) on the third valve heart (15), core bar (14) is relative, in the spring installation sleeve (10) of lower connecting barrel body bottom spring (8) is installed, between spring and the third valve core bar (14) in the heart adapter plate (7) is arranged, push-button switch (6) is installed on the adapter plate, and the push-button switch top has baffle plate (5) to be fixed on lower connecting barrel body bottom.
