Description
Technical field
The utility model relates to a kind of elastic connecting device.
Background technology
Stirred vessel has charging and discharging mouth usually, some stirred vessel discharging openings are not suitable for installing conventional valve opening and closing discharging opening, usually need to adopt drive unit to drive the seal cover opening and closing stirred vessel discharging opening, and the sealing effectiveness after seal cover closedown discharging opening need be guaranteed.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of elastic connecting device for connecting drive device and seal cover.
The utility model solves the technical scheme that its technical problem adopts: a kind of elastic connecting device, for the seal cover of connecting drive device and stirred vessel discharge outlet, comprise shaft coupling, adapter sleeve, adapter sleeve two ends are respectively equipped with left end cap and right end cap, right end cap center is provided with tapped through hole, left end cap center is provided with pilot hole, the connecting axle that can move back and forth vertically is provided with in pilot hole, oil immersion graphite packing is provided with between connecting axle and pilot hole, connecting axle is connected with left end cap key, the connecting axle right-hand member stretched in adapter sleeve endoporus has the retaining shaft shoulder, the left end that connecting axle stretches out pilot hole is connected with shaft coupling, Compress Spring is provided with in adapter sleeve endoporus, Compress Spring two ends offset with right end cap and the retaining shaft shoulder respectively.
The beneficial effects of the utility model are: the utility model one end is connected with the output shaft of drive unit by shaft coupling, the other end is connected with seal cover by extension bar, the tapped through hole that extension bar one end screws in right end cap is threaded with right end cap, during work, drive unit drives the utility model to drive seal cover to cut out by stirred vessel discharging opening, then drive unit continuation driving connecting axle stretches in adapter sleeve endoporus and is compressed by Compress Spring, Compress Spring is compressed to a certain degree, drive unit quits work, can guarantee that the sealing of seal cover to stirred vessel discharging opening reaches stable effect like this.The utility model structure is simple, reliable, long service life.
