Abstract
The utility model provides a kind of tire abrasion alarm device, and it is installed in doughnut groove groove; And described tire abrasion alarm device comprises connecting element and movable part, described connecting element is fixed in tread groove; Described movable part is fixed in tread groove, and one end of described movable part is fixed in tire arm, and the other end of movable part is unsettled, when wear on tyres does not reach police circles' line, in tire rolling process, on movable part, between unsettled end and connecting element, remains separated; And when wear on tyres arrives police circles' line, in tire rolling process, rotate towards connecting element because touching ground end unsettled on movable part, and send the sound after movable part touching connecting element.The touching sound prompting user wear on tyres that the utility model sends in tire rolling process by movable part and connecting element has arrived police circles' line, tire rolling one weekly assembly sends the sound one time, tire in the process of moving, can produce the periodic sound, more easily by user, is discovered.
Description
Technical field
The utility model relates to a kind of tire abrasion alarm device, particularly a kind of tire abrasion alarm device of being convenient to discover.
Background technology
When tire travels on the ground, its tread rubber strip form contacts with ground and is worn by rubbing.For the obvious reason of safety, importantly in the wearing and tearing of tire protector adhesive tape, become excessive and in wet road, (particularly in the darker place of hydrostatic, (at these, locally can have the danger of skidding)) and exist earth-grasping force tire to be replaced before can showing the danger of lowering.For the ease of checking, wear and tear and be convenient to detect especially significantly wearing and tearing, tire is equipped with tread wear indicator conventionally.An example of normally used tread wear indicator is the rib generating in the channel bottom of tire tread pattern, and the height of rib is corresponding to the least depth of the required sipe of the correct reliability service of tire.Therefore, when tire protector adhesive tape is worn, and the top of rib and the outer surface of tread rubber strip form are when concordant, just mean and have reached the least depth that has even surpassed gash depth tolerance.Therefore, for security reasons, in the urgent need to tire is replaced.Utilize a shortcoming of such tread wear indicator to be, need the chaufeur of power actuated vehicle to maintain vigilance to this part, and need to regularly carry out visual inspection to the state of its tire.At present, many chaufeurs can be ignored and carry out such inspection, and excessively late change its tire, for example, while being checked through the wear state of tire when forcing vehicle testing at repair plant, just can change its tire.
Summary of the invention
Main purpose of the present utility model is to provide a kind of tire abrasion alarm device of being convenient to discover.
The utility model provides a kind of tire abrasion alarm device, and it is installed in doughnut groove groove; And described tire abrasion alarm device comprises:
Connecting element, it is fixed in tread groove;
Movable part, it is fixed in tread groove, and one end of described movable part is fixed in tire arm, and the other end of movable part is unsettled, when wear on tyres does not reach police circles' line, in tire rolling process, on movable part, between unsettled end and connecting element, remains separated; And when wear on tyres arrives police circles' line, in tire rolling process, rotate towards connecting element because touching ground end unsettled on movable part, and send the sound after movable part touching connecting element.
Especially, described movable part comprises rod body part, the first jut, the second jut, and the first jut and ground touching, the second jut and connecting element touching.
Compared with prior art, the touching sound prompting user wear on tyres that the utility model sends in tire rolling process by movable part and connecting element has arrived police circles' line, tire rolling one weekly assembly sends the sound one time, tire in the process of moving, can produce the periodic sound, more easily by user, be discovered.
[accompanying drawing explanation]
Fig. 1 is the use view of the utility model tire abrasion alarm device when wear on tyres does not reach police circles' line.
Fig. 2 is the use view of the utility model tire abrasion alarm device when wear on tyres arrives police circles' line.
[specific embodiment]
Refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of tire abrasion alarm device, and it is installed in doughnut groove groove 101; And described tire abrasion alarm device comprises:
Connecting element 20, it is fixed in tread groove 101; Wherein, the two ends of described connecting element 20 are fixed in tire arm 100 by nail pin, and the direction that wears of nail pin is basically parallel to tread surface.
Movable part 30, it is fixed in tread groove 101, and one end of described movable part 30 is fixed in tire arm 100, in the present embodiment, end fixing on described movable part 30 is fixed in tire arm 100 by nail pin, and the direction that wears of nail pin is basically parallel to tread surface.And the other end of movable part 30 is unsettled, when wear on tyres does not reach police circles' line, in tire rolling process, on movable part 30, between unsettled end and connecting element 20, remain separated, movable part 30 and touching mutually of connecting element 20, just can not send the sound yet; And when wear on tyres arrives police circles' line, in tire rolling process, rotate towards connecting element 20 because touching ground end unsettled on movable part 30, and send the sound after movable part 30 touching connecting elements 20.
In the present embodiment, described movable part 30 comprises rod body part 31, the first jut 32, the second jut 33, and the first jut 32 and ground touching, the second jut 33 and connecting element 20 touchings.
Before tire weares and teares, the arm at tread surface place is thick is D0, wear on tyres is during to police circles' line, the arm at tread surface place is thick is D1, according to police circles' line of wear on tyres, determine that connecting element 20 and the setting position of movable part 30 also meet: when wear on tyres does not reach police circles' line, movable part 30 and not touching mutually of connecting element 20, just can not send the sound yet; When wear on tyres arrives police circles' line, movable part 30 is touched mutually with connecting element 20, and sends the sound.
The touching sound prompting user wear on tyres that the utility model sends in tire rolling process by movable part 30 and connecting element 20 has arrived police circles' line, tire rolling one weekly assembly sends the sound one time, tire in the process of moving, can produce the periodic sound, more easily by user, is discovered.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
