Sealing bottom surface seat is cylindrical, hollow tubular structure, its outer wall is provided with annular boss, boss is corresponding with third level step terrace, boss is evenly provided with at least four counter sinks, threaded hole one_to_one corresponding on counter sink and third level step, sealing bottom surface seat is arranged on the small end face of adapter shoe by counter sink and threaded hole by screw, the cylinder of boss side is arranged in the hollow of adapter shoe, the cylinder outward flange of boss opposite side is provided with chamfering, chamfering place is provided with O type circle, the side that small end face is close to by boss is provided with at least four helical spring locating slots, location hole of the spring one_to_one corresponding on spring locating slot and third level step, mounting spring between spring locating slot and location hole of the spring.
The technical scheme that the utility model limits further is:
Aforementioned large end face is provided with annular groove, arranges sealing strip in annular groove.
The beneficial effects of the utility model are:
The utility model arranges spring in the junction of sealing bottom surface seat and adapter shoe, when the end face of sealing bottom surface seat and adapter shoe is fitted, in order to prevent centre from having excessive space, uses spring device to compensate; In addition, chamfering is provided with in the outer face of sealing bottom surface seat, and be provided with O type circle at chamfering place, when connecting sample axle or tested tubular shaft, pop one's head in clamping stagnation when forward-reverse or pause can be prevented, make to connect transient process round and smooth smooth and easy, and this product is easy for installation, operation is succinct, facilitates the maintenance of hole-bored axle from end to end, not only increase work efficiency in use procedure, and extend the serviceable life of product.
