Abstract
The utility model discloses an alarm annunciator for monitoring air pressure of the tires. An aeration channel (9) is composed of a valve cover (2) and a valve seat (7) which is connected with the valve cover; an alarm whistle (1) is arranged at the export of the valve cover (2). A positioning pad (8) is arranged in the aeration channel (9) and between the valve cover (2) and the valve seat (7). A T-shaped gas pressure pad (6) with a sealing gasket (5) is arranged on the one side of the positioning pad (8) near the valve seat (7), the straight rod of the T-shaped pressure pad (6) crosses the positioning pad (8) and inserts into the aeration channel (9) of the valve cover (2). The positioning pad (8) is sealed by the sealing gasket (5) arranged on the T-shaped gas pressure pad (6). A guide pad (4) is arranged in the aeration channel (9) of the valve cover (2), which is contacting with the T-shaped gas pressure pad (6) directly. A spring (3) is installed between the guide pad (4) and the valve cover (2). The device is capable of alarming when the air pressure of the pneumatic tire is insufficient, which is simple in structure and low in cost.
Description
Technical field: the utility model relates to a kind of annunciator, particularly relates to a kind of tire pressure alarm.
Background technology: along with the development of society, the increasing vehicle enter in the middle of people's work and the life, and these vehicle mostly adopt air-inflation tyre to travel.These air-inflation tyres have been brought into play important effect at aspects such as walking, vibration damping, protection road surfaces.But, these air-inflation tyres are when bringing convenience to people's life, and also there are some shortcomings in itself, are exactly gas leakage easily, gas leakage back low tyre people generally can not aware, and have in use brought the potential safety hazard that can not be ignored to safety traffic.
Technology contents: technical problem to be solved in the utility model provides a kind of device that can report to the police when air-inflation tyre air pressure is not enough.
The technical solution adopted in the utility model is: a tire pressure alarm is installed on airtyred tire tube valve.The structure of this tire pressure alarm is such: valve gap and valve seat connect to form a filling channel, and the filling channel inlet in the valve seat can be communicated with airtyred tire tube valve, and the filling channel outlet correspondence in the valve gap is equipped with alarm hooter; In filling channel, between valve gap and the valve seat, locating pad is housed, the T type air pressure pad of band packing seal is housed by valve seat one side at locating pad, the straight-bar of T type air pressure pad passes in the filling channel that locating pad stretches into valve gap, and the packing seal that is contained on the T type air pressure pad can seal locating pad; The guiding pad is housed in the filling channel of valve gap, between guiding pad and the valve gap spring is housed, the guiding pad contacts with the straight-bar of T type air pressure pad.
When the air pressure in the air-inflation tyre met the inflation standard pressure, the gas in the air-inflation tyre was pushed down T type air pressure pad, made packing seal push down the locating pad sealing, did not have gas to spill, and alarm hooter can not ring, and air-inflation tyre can normally use.
When air-inflation tyre internal gas pressure deficiency, when being lower than the inflation standard pressure, the pressure of spring is greater than the air-inflation tyre internal gas pressure, spring retreats by guiding pad compression T type air pressure rim strip dynamic seal pad, and gas is overflowed from air-inflation tyre, through filling channel, blow alarm hooter, realize reporting to the police.
Take off annunciator, just can in air-inflation tyre, inflate.
Owing to adopted technique scheme, packing seal and spring are housed in filling channel, in the filling channel outlet alarm hooter is housed, like this, when air-inflation tyre internal gas pressure air pressure not up to standard, under action of the spring, guiding pad compression T type air pressure rim strip dynamic seal pad retreats, and gas evolution are blowed alarm hooter, thereby reaches the purpose that air-inflation tyre air pressure can be reported to the police when not enough, and this apparatus structure is simple, and is cheap.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment: valve gap 2 connects to form a filling channel 9 with valve seat 7, and filling channel 9 inlets in the valve seat 7 can be communicated with airtyred tire tube valve, and the outlet correspondence of the filling channel 9 in the valve gap 2 is equipped with alarm hooter 1; In filling channel 9, between valve gap 2 and the valve seat 7, locating pad 8 is housed, the T type air pressure pad 6 of band packing seal 5 is housed by valve seat 7 one sides at locating pad 8, the straight-bar of T type air pressure pad 6 passes in the filling channel 9 that locating pad 8 stretches into valve gap 2, and the packing seal 5 that is contained on the T type air pressure pad 6 can seal locating pad 8; Guiding pad 4 being housed in the filling channel 9 of valve gap 2, between guiding pad 4 and the valve gap 2 spring 3 being housed, guiding pad 4 contacts with the straight-bar of T type air pressure pad 6.
When the air pressure in the air-inflation tyre met the inflation standard pressure, the gas in the air-inflation tyre was pushed down T type air pressure pad 6, made packing seal 5 push down locating pad 8 sealings, did not have gas to spill, and alarm hooter 1 can not ring, and air-inflation tyre can normally use.
When air-inflation tyre internal gas pressure deficiency, when being lower than the inflation standard pressure, the pressure of spring 3 is greater than the air-inflation tyre internal gas pressure, spring 3 drives packing seal 5 by guiding pad 4 compression T type air pressure pads 6 and retreats, and gas is overflowed from air-inflation tyre, through filling channel 9, blow alarm hooter 1, realize reporting to the police.
Claims (2)
1, a kind of tire pressure alarm, it is characterized in that: valve gap (2) connects to form a filling channel (9) with valve seat (7), filling channel (9) inlet in the valve seat (7) can be communicated with airtyred tire tube valve, and filling channel (9) the outlet correspondence in the valve gap (2) is equipped with alarm hooter (1); In filling channel (9), between valve gap (2) and the valve seat (7), locating pad (8) is housed, the T type air pressure pad (6) of band packing seal (5) is housed by valve seat (7) one sides at locating pad (8), the straight-bar of T type air pressure pad (6) passes in the filling channel (9) that locating pad (8) stretches into valve gap (2), and the packing seal (5) that is contained on the T type air pressure pad (6) can seal locating pad (8); Guiding pad (4) is housed in the filling channel (9) of valve gap (2), between guiding pad (4) and the valve gap (2) spring (3) is housed, guiding pad (4) contacts with the straight-bar of T type air pressure pad (6).
