Description
Technical field
The utility model relates to mobile unit technical field, is specifically a kind of water proof type vehicle-mounted detection apparatus.
Background technology
There is a kind of vehicle-mounted detection apparatus at present, it comprises housing, the ultrasonic probe being arranged on the testing circuit in housing and being arranged on outside housing, described ultrasonic probe is connected with described testing circuit by signal wire, also comprise warning horn, the signal output part of described testing circuit is connected with central processing unit, the output terminal of described central processing unit is connected with warning horn, described housing is provided with installation groove, described installation groove has been provided with fixed support, described fixed support is removably connected by two symmetrical supports and forms, described fixed support is provided with resilient feet, although mount and dismount all very convenient on car body, decrease the spoilage of vehicle-mounted detection apparatus in disassembly process, but feet is separate, globality is poor, feet contacts with car body and is close to as point cantact, lifting surface area is little, poor stability, easily loosen, after loosening, extraneous rainwater very easily infiltrates in car from the binding face of ultrasonic probe and car body, non-watertight, simultaneously fixed support is removably connected by two symmetrical supports and forms, structural strength is lower, and fixed support is installed on installation groove, and the distance of installing between groove and ultrasonic probe is fixing, therefore the distance between fixed support and ultrasonic probe is fixing, the environment for use of the distance changed between fixed support and ultrasonic probe cannot be met the needs of, adaptability is poor.
Utility model content
Technical problem to be solved in the utility model is, overcomes the defect of prior art, provide a kind of waterproof, globality and stability better, higher, the good water proof type vehicle-mounted detection apparatus of adaptability of structural strength.
For solving the problems of the technologies described above, the utility model proposes a kind of water proof type vehicle-mounted detection apparatus, it comprises housing, the ultrasonic probe being arranged on the testing circuit in housing and being arranged on outside housing, ultrasonic probe is electrically connected with testing circuit, the face offseted that contacts with car body of ultrasonic probe is provided with ring groove, ring groove is provided with O-ring seal, housing slip cap is connected to fixed support, housing has been threaded for the support bracket fastened nut of axial limiting, housing is arranged with the packing ring between fixed support and ultrasonic probe, be provided with between packing ring and fixed support sequentially arrange along fixed support circumference multiple there is flexible feet, one end of feet is all connected with packing ring, the other end of feet is all connected with fixed support.
After adopting said structure, compared with prior art, the utility model has the following advantages: during installation, O-ring seal realizes water-tight, extraneous rainwater is stoped to infiltrate in car from the binding face of ultrasonic probe and car body, and packing ring contacts with car body and utilizes feet elasticity to offset, each feet connects and forms entirety by packing ring, globality is better, and packing ring and car body are face contacts, stability is better, not easily loosen, simultaneously to be not that two parts are removable like prior art be formed by connecting fixed support, but it is overall, therefore structural strength is higher, and support bracket fastened axial location is adjusted by nut, make the distance between fixed support and ultrasonic probe adjustable, therefore adaptability is better.
As improvement, multiple feet is uniformly distributed along fixed support circumference, and like this, the strength of applying is even, more reliable and more stable after the utility model is installed.
As improvement, nut is self-locking nut, like this, prevents reversion from getting loose, is applicable to the vibration environments such as vehicle, and structure is simple simultaneously.
As improvement, fixed support is the circular slab that through hole is established at middle part, and like this, processing is simple, and production cost is low, and intensity is high simultaneously.
As improvement, the diameter of circular slab is greater than the diameter of nut, and like this, nut and circular slab offset completely, fixing more reliable and more stable to circular slab.
