Locking flap with housing between two flanges - has through bore, and elastically deformable struts for two facing flange screws

摘要

The locking flap has a housing (1) wedged between two flanges so that is through-flow hole is flush with the through-flow holes in the flanges. At least one end of the locking-flaps housing (1) has elastically deformable struts (8) for at least two facing flange-screws (9,10). The struts (8) are formed on the lining (4) of the locking flap and are joined to the lining (4) by means of bridge pieces (14) which lead via holes (13) in the metal end (7) of the locking flap's housing (1). USE/ADVANTAGE - The locking flap is automatically centred by struts covering holes varying between a max. and min. dia.
