Title:

DISCHARGE OUTLET FIXING CLAMP FOR MEDIUM-SIZED BULK CONTAINERS

Document Type and Number:

WIPO Patent Application WO/2016/023469

Kind Code:

A1

Abstract:

A discharge outlet fixing clamp (2) for medium-sized bulk containers. The discharge outlet (1) comprises a flange edge (3), a discharge connecting port (5) and a discharge outlet clamping position (4). The discharge outlet clamping position (4) is a polygonal structure. The fixing clamp (2) comprises a fixing clamp body, a clamping part (8), elastic leading-in ribs (7) and non-return parts (9). A passage for accommodating the discharge outlet clamping position (4) is formed in the middle part of the fixing clamp body. The clamping part (8) is used for clamping the side edge of the discharge outlet clamping position (4) after the fixing clamp (2) and the discharge outlet (1) have been assembled. When the leading-in surfaces of the elastic leading-in ribs (7) contact with the side edge of the discharge outlet clamping position (4), the elastic leading-in ribs (7) are squeezed by the side edge of the discharge outlet clamping position (4) to deform. After the fixing clamp (2) and the discharge outlet (1) have been assembled, the elastic leading-ribs (7) return elastically, and the non-return parts (9) are matched with the side edge of the discharge outlet clamping position (4) to prevent the fixing clamp (2) from being separated from the discharge outlet (1). The fixing clamp (2) can be transversely pushed in to be assembled with the discharge outlet (1). The fixing clamp has low requirements for assembly accuracy, and is favorable for saving cost and increasing efficiency.
