Abstract

A fixing clamp ( 2 ) for discharge outlet of intermediate bulk containers is disclosed. The discharge outlet ( 1 ) comprises a flange edge ( 3 ), a discharge connecting port ( 5 ) and a discharge outlet clamping part ( 4 ). The discharge outlet clamping part ( 4 ) is a polygonal structure. The fixing clamp ( 2 ) comprises a fixing clamp body, a clamping portion ( 8 ), elastic guiding ribs ( 7 ) and anti-release portion ( 9 ). A passage for accommodating the discharge outlet clamping part ( 4 ) is formed in the middle part of the fixing clamp body. The clamping portion ( 8 ) is used for clamping the side surface of the discharge outlet clamping part ( 4 ) when the fixing clamp ( 2 ) and the discharge outlet ( 1 ) have been assembled. The elastic guiding ribs ( 7 ) will be squeezed by the side surface of the discharge outlet clamping part ( 4 ) to deform When the leading-in surfaces of the elastic guiding ribs ( 7 ) contact with the side surface of the discharge outlet clamping part ( 4 ). The elastic guiding ribs ( 7 ) restore elastically and the anti-release portion ( 9 ) are engaged with the side surface of the discharge outlet clamping part ( 4 ) to prevent the fixing clamp ( 2 ) from being separated front the discharge outlet ( 1 ) after the fixing clamp ( 2 ) and the discharge outlet ( 1 ) have been assembled. 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.

First claim

What is claimed is:

1. A fixing clamp for a discharge outlet of an intermediate bulk container, wherein the intermediate bulk container is provided with a discharge passage, and the fixing clamp is used to fix the discharge outlet in the discharge passage, wherein the discharge outlet comprises a flange edge, a discharge connecting port and a discharge outlet clamping part, wherein the discharge outlet clamping part is a polygonal structure, and the fixing clamp comprises:
a fixing clamp body, wherein an opening is provided at one end of the fixing clamp body, and a passage for accommodating the discharge outlet clamping part is formed in the middle part of the fixing clamp body;
a clamping portion, wherein the clamping portion has a profile forming said passage, and the clamping portion is used for clamping the side surfaces of the discharge outlet clamping part when the fixing clamp and the discharge outlet have been assembled;
elastic guiding ribs, wherein the elastic guiding ribs are provided at the opening end of the fixing clamp body and are connected fixedly to the fixing clamp body with their proximal end, wherein leading-in surfaces are provided on the elastic guiding ribs, and the leading-in surfaces contact with the side surfaces of the discharge outlet clamping part when the fixing clamp is pushed in laterally with respect to the discharge outlet, such that the elastic guiding ribs are deformed due to being squeezed by the discharge outlet clamping part, and the elastic guiding ribs return elastically when the fixing clamp and the discharge outlet have been assembled; and
anti-release portions, wherein the anti-release portions are extended integrally from the distal ends of the elastic guiding ribs respectively and are provided such that when the fixing clamp and the discharge outlet have been assembled, the anti-release portions are engaged with the side surfaces of the discharge outlet clamping part to prevent the fixing clamp from being separated from the discharge outlet.

2. The fixing clamp according to claim 1 , wherein the anti-release portions are provided with anti-release surfaces, wherein when the assembled, the anti-release surfaces abut against the side surfaces of the discharge outlet clamping part to prevent the fixing clamp from being detached from the discharge outlet.

3. The fixing clamp according to claim 2 , wherein the distal end of the anti-release portion is provided with a position-limiting rib, and the opening end of the clamping portion is provided with a position-limiting step, and the position-limiting step being capable of preventing movement of the anti-release portion in a direction away from said discharge outlet when the position-limiting rib is engaged with the position-limiting step.

4. The fixing clamp according to claim 1 , wherein the discharge passage of the intermediate bulk container is square in cross-section, and the shape and size of the fixing clamp body are matched to the shape and size of the interior perimeter of the discharge passage.

5. The fixing clamp according to claim 1 , wherein the anti-release portion is an anti-return hook provided at the distal end of the elastic guiding rib, and an anti-return part is provided on the discharge outlet clamping part correspondingly, wherein when the fixing clamp and the discharge outlet are assembled, the anti-return hook is engaged with the anti-return part so that the fixing clamp can be prevented from being released from the discharge outlet.

6. The fixing clamp according to claim 1 , wherein the clamp body is further provided with an elastic connecting buckle for engaging with the discharge passage of the intermediate bulk container when the fixing clamp is assembled to the discharge outlet, thereby fix the discharge outlet with respect to the discharge passage of the intermediate bulk container.

7. The fixing clamp according to claim 1 , wherein the passage of the fixing clamp is shaped and sized to mate with the discharge outlet clamping part such that the clamping portion engages with the side surfaces of the discharge outlet clamping part tightly.

8. The fixing clamp according to claim 1 , wherein the fixing clamp is made of elastic plastic.

9. The fixing clamp according to claim 1 , wherein the cross-sectional shape of the discharge outlet clamping part of the fixing clamp is quadrilateral or hexagonal.
