Sheath can expand jam-packed nut alveolus outward.Then it is screwed into screw rod and carries out up and down adjustment.Screw rod is passing through filter adjusting screw rod
When the recoil inserts of locking device, with by regular screw threads hole compared to torque will increasing, so that it is more stable to be allowed to up and down adjustment,
And the height after adjusting can be fixed.Play the effect locking to screw rod again simultaneously.
Further, the screw thread of the recoil inserts is polygonal coil.When adjusting screw rod enters in the coil, spiral shell
The straightway of line sheath can press and lock adjusting screw rod.Reach locking, increases the effect of effective torque.
Further, the polygonal coil quantity is a circle or multi-turn.Convenient for enhancing its tightness, tie down screw,
Prevent adjusting screw rod from loosening.And the dynamics that screw rod can be locked according to product needs, regulation locking device, it may be assumed that Ke Yishi
The changeability of existing torque.
Further, the top, lower part or middle part of the recoil inserts is arranged in the polygonal coil.Polygon line
The upper, middle and lower any position that recoil inserts is arranged in circle can realize pressure and lock adjusting rod, play locking effect.
Further, the filter cover board and the embedded connection of the retention mechanism.
Further, the retention mechanism includes adapter sleeve ontology and retainer plate, the adapter sleeve ontology and retainer plate one
Body formed, the retainer plate surrounding is evenly arranged with plurality of bump, the circular hole inner sidewall be uniformly provided with it is a plurality of convex
The compatible groove of block.
The advantage of the utility model is: compared with the prior art, in the utility model, by by retention mechanism pressure
On the circular hole of filter lid plate surface, retention mechanism is fixed.In addition, recoil inserts is screwed into the threaded hole of retention mechanism
After fixation, recoil inserts can expand jam-packed nut alveolus outward.It may be implemented in the case of any high/low temperature, locking device does not have
Fall off loose situation.Installation has the recoil inserts of self-tightening screw thread inside retention mechanism.Then screw rod is screwed into carry out up and down
It adjusts.Screw rod can become torque increasing, so that it is more steady to be allowed to up and down adjustment in the recoil inserts by having self-tightening screw thread
It is fixed, and the height after adjusting can be fixed.Play the effect locking to screw rod again simultaneously.By screw rod in recoil inserts
On up and down adjustment, also may be implemented the adjusting to filter signal, and after height adjustment is stablized, on recoil inserts from
Tight screw thread can be used for stablizing the height of screw rod, promote overall structure by the ability of external interference.This structure locks the same of screw rod
When, screw flight will not be damaged.Compared to self-locking structure, the height of the screw rod up and down adjustment of the utility model are arranged on screw rod
It spends unrestricted, and utmostly screw thread can be protected not to be damaged.Finally, the installation of this structure is simple, without manually installed,
Full-automatic installation can be realized easily.
