Rasp bar 21 is moved up and horizontal, the drive expansion wall 24 maximization expansion.
In certain embodiments, the position limiting structure 23 can also be fixed on the lower surface of protection cap 20 with for outer spiral shell
Rasp bar 21 is arranged in cylindrical positive stop lug boss therein, and the cylindrical positive stop lug boss is concentric with external thread rod 21, external diameter with
Floor drain lower end bore matches.The position limiting structure 23 can according to demand make in various embodiments corresponding change,
As long as can limit when supporting hinges are the level of state being moved in the expansion continuation of wall 24.
In the present embodiment, protective case 28 is cased with the locking nut 22 of floor drain protection cap 20, external screw thread during preventing
Bar 21 gets rusty, pollutes and bad dismounting.In the case of without instrument, it is impossible to open the draining of floor drain protection cap 20, impurities removal thing with handss.
This utility model embodiment, when mounted, by the upper end of external thread rod 21 protection cap 20 is passed, then by locking nut
22 twist in the upper end exposed, and then by the lower end of external thread rod 21 by from floor drain 1 is penetrated, protection cap 20 is placed in the upper port of floor drain 1
Place, now expands wall 24 and is located in drain pipe 3, and due to not tightening locking nut 22, the upper end of position limiting structure 23 is not butted on
The lower surface of protection cap 20, the second end of each supporting hinges is in state upwardly and outwardly；Locking nut 22 is finally tightened,
The gradually upper shifting of external thread rod 21 is made, is driven and moved on each group of supporting hinges component and expansion wall 24, until the upper end of position limiting structure 23
In the lower surface of protection cap 20, lower end withstands expansion wall 24 and continues to move up, so that the second of each supporting hinges at bottom
End keeps, and now external thread rod 21 continues to upper shifting with tightening for locking nut 22, continues to drive each group of bloster hinge
Chain is moved on continuing, so that the first end of each supporting hinges is continued to move up, pivoted arm is gradually horizontal, expands wall 24
It is expanded to maximum（In different instances, corresponding tonicity is varied from, and is determined according to example）, external diameter and draining bore phase
Matching, produces maximal friction（Determined according to different instances）, tightening retaining nuts 22, by with the frictional force of inside pipe wall with lock
The cooperation of tight nut 22 reaches and protection cap 20 is lock onto at the upper port of floor drain 1.
Compared with prior art, floor drain protection device of the present utility model has the advantage that：
1st, effective protection floor drain and bottom drain pipe 3 are destroyed and block.
2nd, replacing, dredging floor drain and drain pipe 3 are omitted, a large amount of artificial and Master Costs are saved.
