Abstract
The invention discloses an external tire pressure sensor which comprises a sensor body and a shell, wherein the sensor body is arranged inside the shell; an air guide hole is formed in a side wall of the shell; the external tire pressure sensor also comprises a fixing lug ring and an air guide tube; the fixing lug ring comprises a fixing shaft and two fixing rings arranged on two sides of the fixing shaft; the fixing shaft is fixedly connected with the bottom surface of the shell; the air guide tube is connected with the air guide hole in the shell through a three-way air guide valve; and an another port of the three-way air guide valve is empty. According to the external tire pressure sensor disclosed by the invention, the sensor body is fixed on an automobile rim through the fixing lug ring and is fixed by using a large screw, and if the sensor is needed to be detached, the screw is unscrewed by using a pneumatic hammer, and the sensor is prevented from being dropped or stolen. Meanwhile, a tire valve and the sensor of the automobile are communicated through the three-way air guide valve, only the empty end of the three-way air guide valve is needed to be inflated during inflation, and the pressure sensor is convenient and rapid.
Description
Technical field
The present invention relates to a kind of tire pressure sensor, in particular, relate to a kind of external tire pressure sensor, belong to TPMS technical field.
Background technology
Monitoring tire pressure is also known as TPMS, that Real-Time Monitoring is carried out to the air pressure of motor tire and temperature, display of tyre pressure and temperature numerical value, car owner is allowed to grasp tire pressure temperature conditions at any time, Timeliness coverage tire flat, air pressure are not enough, air pressure crosses high situation, avoid blowing out and the traffic accident that causes.Current TPMS sensor is all carry out real-time automatic monitoring to tire pressure and temperature in vehicle stationary or driving process, and carries out and alarm tire high pressure, low pressure, high temperature, avoids the traffic accident because tire fault causes, to guarantee traffic safety.Now, on market, monitoring tire pressure product is easy for installation, without the need to tearing tire open, as long as be screwed in by sensor on tire tube valve just passable.But after sensor installation, tyre inflating inconvenience, need unload sensor during inflation, be loaded on after having inflated, waste a large amount of human costs, bring puzzlement to user, meanwhile, owing to dismantling easily, automobile be also easily cause in driving process come off lose or by people for stealing.
Summary of the invention
Goal of the invention: the object of the invention is for the deficiencies in the prior art, provide a kind of easy disassembly, anti-lost antitheft, be conducive to inside tire inflation external tire pressure sensor.
Technical scheme: a kind of external tire pressure sensor of the present invention, comprise sensor body and housing, described sensor body is arranged at described enclosure interior, the side-walls of described housing arranges gas port, also comprise fixed lug and ventilation flue, described fixed lug comprises anchor shaft and is arranged at two set collars of described anchor shaft both sides, and described anchor shaft is fixedly connected with the bottom surface of described housing; Described ventilation flue is connected with the gas port on described housing by threeway guide valve, and another port of described threeway guide valve puts sky.
Being further defined to of technical solution of the present invention, the distance between described two set collars is identical with the distance between adjacent two screws on the wheel rim of automobile to be installed.
Further, the bottom surface of described housing arranges draw-in groove, and described anchor shaft is fixedly installed on described draw-in groove.
Further, described anchor shaft and two set collars one-body molded.
Beneficial effect: a kind of external tire pressure sensor provided by the invention, is fixed on automobile rim by fixed lug by sensor body, fixes with king bolt, if need dismounting, needs to be laid by screw with wind big gun, prevents from dropping or being stolen; Meanwhile, the tire tube valve of automobile is communicated with sensor by threeway guide valve by the present invention, only needs to be undertaken inflating by the dead end of putting of threeway guide valve when inflating, when especially having a twin tire for cart, more convenient to the inflation of inside tire; Structure of the present invention is simple, and cost of manufacture is low, and installation method is easy to operate, easy to utilize.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of external tire pressure sensor provided by the invention;
Fig. 2 is the structural representation of the fixed lug of a kind of external tire pressure sensor provided by the invention.
Detailed description of the invention
Below by accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
embodiment 1:a kind of external tire pressure sensor that the present embodiment provides, its structural representation as shown in Figure 1, comprises sensor body and housing 1, it is inner that sensor body is arranged at housing 1, the side-walls of housing 1 arranges gas port, and gas port is communicated with inside tires, detects the pressure of inside tires.
Present embodiments provide special sensor housing fixed form, comprise fixed lug 2 and ventilation flue 3.
The structural representation of fixed lug 2 as shown in Figure 2, comprises anchor shaft 4 and is arranged at two set collars 5 of anchor shaft both sides, anchor shaft 1 and two set collars 5 one-body molded, stabilized structure.Distance between two set collars 5 is identical with the distance between adjacent two screws on the wheel rim of automobile to be installed, convenient fixed installation.The bottom surface of housing 1 arranges draw-in groove, and anchor shaft 4 is fixedly installed on described draw-in groove, is fixedly connected with the bottom surface of housing 1.In the present embodiment, fixed lug 2 is steel, and the width of anchor shaft 4 is 15 ~ 20cm, and fixed sturcture is firm, difficult drop-off.
Ventilation flue 3 is connected with the gas port on housing 1 by threeway guide valve 6, and another port of threeway guide valve 6 puts sky, and after entrucking, the other end of ventilation flue 3 is communicated with the valve port of automobile.
A kind of external tire pressure sensor that the present embodiment provides, is assemblied on automobile rim by two set collars 5 by the housing 1 of sensor, fixes with king bolt, if will dismantle, needs to be laid by screw with wind big gun, has therefore possessed anti-theft feature.The tire tube valve of automobile is communicated with sensor by threeway guide valve by the present embodiment, sensor can be real-time monitoring tire in air pressure, the design of unique threeway guide valve, making it can when not removal sensor, inflation pump and threeway guide valve are put empty one end to be connected, can inflate tire, convenient and swift.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
