Description
Technical field
The utility model relates to mobile unit technical field, is specifically the vehicle-mounted waterproof detection device of a kind of high strength detachable.
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 (SW), also comprise siren horn, the signal output part of described testing circuit is connected with central process unit, the mouth of described central process unit is connected with siren 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 Assembly &Disassembly is all very convenient on car body, decrease the damage rate of vehicle-mounted detection apparatus in disassembly process, but feet is very thin weakness after all, in vehicle Long-Time Service, easily there is fatigue failure, and then cause getting loose, break down, and get loose the situation that extraneous rainwater infiltrates from the binding face of ultrasonic probe and car body in car easily occurs, 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, comformability is poor.
Utility model content
Technical problem to be solved in the utility model is, overcomes the defect of prior art, provides one not easily to get loose, waterproof, structural strength are higher, the vehicle-mounted waterproof detection device of comformability good high strength detachable.
For solving the problems of the technologies described above, the utility model proposes the vehicle-mounted waterproof detection device of a kind of high strength detachable, 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 circular groove, circular groove is provided with seal ring, 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 first elastic sequentially distributed from inside to outside along housing radial direction between fixed support and ultrasonic probe, spring, second elastic, spring and by the circular cylindrical hole bearing fit formed between the first elastic and the second elastic.
After adopting said structure, compared with prior art, the utility model has the following advantages: before not installing, its length is longer than the first elastic and the second elastic, after installation, then spring, first elastic and the second elastic are all compressed into intimate isometric, the utility model is arranged on after on car body, seal ring realizes water-tight, extraneous rainwater is stoped to infiltrate in car from the binding face of ultrasonic probe and car body, originate as the elasticity that the utility model is fixing with spring, and provide strength support by the first elastic and the second elastic, require less to spring force, circular cylindrical hole forms guiding and protective effect to spring, spring is made to have increased durability and stability, therefore not easily get loose, be beneficial to seal ring to play a role, realize waterproof object, 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 comformability is better, the length of the first elastic and the second elastic is adjusted to be suitable for installing according to this distance.
As improvement, spring is cylinder stage clip, and like this, after the utility model is mounted, what spring presented is compressive state, adopts cylinder stage clip pointed, and more reliable and more stable after the utility model is installed, durability is better.
As improvement, nut is self lock 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 productive costs 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.
