Pit is coaxial with the second threaded hole and specification is in the same size.Second threaded hole and third threaded hole are used for multi-functional range limiter
Installation.
Working principle of the utility model is: upper casing counterbore is covered on lower casing lateral surface, upper and lower shell is locked with installation bolt
Tightly, the annular rib on lower casing flattens the first O-ring seal, and the first O-ring seal fills up ring packing groove, has reached
Hermetically sealed effect；The effect that second O-ring seal on bolt also functions to sealing waterproof is installed simultaneously；Under round boss reduces
Rainy day installs ponding at bolt, also functions to the effect of waterproof；Limiter installation is to be screwed into lower casing second from the bottom up by bolt
It in threaded hole among mounting platform and stabilizer blade and locks, bolt is installed and limiter installation is not exposed with bolt lateral surface
In air, it is not easy to get rusty；Reduce the cost of the long metal screw of original structure simultaneously.
Compared with prior art, the utility model has the beneficial effects that structure is simple, easy for installation, the setting of counterbore makes
Upper casing covers in outside lower casing, and the first O-ring seal is set to inside and does not allow easy to aging, guarantees that upper and lower shell is fully sealed, round boss
And second O-ring seal setting, guarantee installation bolt at sealing, substantially increase waterproof performance, extend limiter
Service life；Upper and lower shell installation bolt and limiter installation are not exposed in air with bolt lateral surface, it is not easy to raw
Rust, while saving the cost of long metal screw.
