The utility model provides a kind of wagon detector, please refers to Fig.1 and Fig. 2, the wagon detector are included for vehicle
Fixing device 100, vehicle detection chip 200 and the battery of detection chip；Vehicle detection chip 200 is mounted on installation cavity 11
Interior, battery is mounted in installation cavity 11, and battery is electrically connected with vehicle detection chip 200.
It please refers to Fig.1 and Fig. 2, the fixing device 100 for being used for vehicle detection chip includes housing 1, cover 2 and sealing
Circle 3；Housing 1 has the annular step 12 of opening up installation cavity 11 and the side wall for being arranged on 1 upper end of housing, ring-shaped step
Portion 12 has the annular step surface 121 set upward and the annular electrolysis 122 being disposed adjacent with annular step surface 121；Lid
The lid of body 2 closes installation cavity 11 and sets, and the outer peripheral edge of cover 2 is downwardly extending the stopping for annular abutted with annular step surface 121 and supports
Portion 21；Sealing ring 3 is socketed on annular step 12, between sealing-in annular electrolysis 122 and the medial surface of retaining part 21
Gap；Wherein, annular step surface 121 and retaining part 21 are fixed by circumferential limiting structure 4, annular step surface 121 and retaining part
Sealed set (is also not shown) by fluid sealant between 21.
For wagon detector for being detected to vehicle, operating environment is typically machine oil, has corruption to vehicle detection chip 200
Erosion acts on, however 100 sealing performance of fixing device of vehicle detection chip is bad or easily by the corruption of machine oil in the prior art
It loses and leads to seal failure.In the prior art also have cover 2 be directly crimped on what is sealed on sealing ring 3, it is this over time,
Sealing ring 3 is loosened and even seal failure of easily spinning by corrosion.It needs to wear in cover 2 by vehicle detection chip 200
Go out cable, testing result is transferred out by cable, cable is easily damaged if cover 2 is spinned or is rotated.
The utility model is sleeved on by sealing ring 3 on annular step 12, and retaining part 21 is socketed on annular step 12
And pass through the gap between 3 sealing-in annular electrolysis 122 of sealing ring and the medial surface of retaining part 21, in 121 He of annular step surface
Retaining part 21 is fixed by circumferential limiting structure 4, can be rotated to avoid cover 2 relative to housing 1, at circumferential limiting structure 4 also
It is sealed by fluid sealant, enhances circumferential 4 fixed stability of limiting structure, by improving the stability of sealing, solve
The problem of sealing ring 3 is loosened by corrosion and is spinned.
Circumferentially fixed structure can be buckle structure, and annular step surface 121 prevents circumferential fortune with retaining part 21 by buckle
It is dynamic.Such as shackle member is set in annular step surface 121, the fastener of setting and shackle member cooperation on retaining part 21.It is circumferential
Fixed structure can also be other structures that can prevent 1 relative rotation of opposite housing of cover 2.Provided by the utility model
In one embodiment, referring to Fig. 3, circumferential limiting structure 4 is included in annular step surface 121 and upwardly extends the convex extension part 41 to be formed,
And the mating groove 42 for coordinating with convex extension part 41 and setting downward set in retaining part 21；Fluid sealant coats convex extension part 41 and matches
Close the junction of slot 42.Convex extension part 41 is inserted into mating groove 42 during installation, then coats fluid sealant in junction, can be further steady
Gu the stability of circumferentially fixed structure.In this way, even if having part fluid sealant or sealing ring 3 to be corroded, cover 2 will not be with respect to shell
Body 1 spins.
In another embodiment provided by the utility model, referring to Fig. 4, circumferential limiting structure 4 can also include difference
The first groove, the second groove being arranged in annular step surface 121 and retaining part 21, the first groove is opposite with the second groove to be set
It puts, fluid sealant coats the first groove and the second groove, in this way, can increase the area of fluid sealant, prevents cover 2 with respect to housing 1
It spins.
After the lid of cover 2 closes installation cavity 11, for cover 2 is avoided easily to deviate from, annular 122 inwardly downward setting of electrolysis
And angle of inclination is A, in this way, annular electrolysis 122 is wide at the top and narrow at the bottom, after retaining part 21 is socketed on annular electrolysis 122 because
Backstop for upper end avoids.A is excessive, and cover 2 covers when on annular electrolysis 122 that resistance is excessive, it is not easy to cover；
A is too small, and resistance is too small, does not have the effect for preventing cover 2 from deviating from.It is 15 °≤A≤18 °, better.
Gap between annular electrolysis 122 and the medial surface of retaining part 21 is h, is difficult the effect for playing sealing when h is excessive
Fruit, h are too small, it is difficult to the setting sealing ring 3 between annular electrolysis 122 and the medial surface of retaining part 21,0.1mm≤h≤
0.2mm。
For the ease of installing vehicle detection chip 200, the bottom wall of installation cavity 11, which upwardly extends, to be formed two and sets side by side relatively
The clamping portion 13 put, the upper end of two clamping portions 13 are correspondingly provided with hook part 131 relatively side by side, and hook part 131 is bottom-up in gradually
Contracting setting.In this way, vehicle detection chip 200 above clamping portion 13 is pressed and the resistance of hook part 131 is overcome to enter two cards
Between socket part 13, installed with this and limit vehicle detection chip 200, in this way, vehicle detection chip 200 install it is simple, conveniently.
Preferably, hook part 131 is plastic material, in this way, hook part 131 has elasticity when vehicle detection chip 200 is caught in,
And avoid damage vehicle detection chip 200 and clamping portion 13.
It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every
Under the utility model design of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes or directly/is used in other related technical areas indirectly and is included in the scope of patent protection of the utility model.
