FIXING CLAMPING DEVICE Russian patent published in 2018 - IPC F16B1/00 F16B21/08 

FIELD: machine building.

SUBSTANCE: invention relates to the field of the structural elements assembly and is aimed at increase in the rigidity and increase in the mechanical tear resistance. Fastening device consists of mounting bracket including head and deformable gripping element, which extends under the head in the axial direction and defines separated from the head in the axial direction clamping surface; gripping element is pushed through the part and the support element so, that their fastening occurred by means of the part and the support element clamping between the bracket head and the clamping surface; gripping element is made so, that the clamping surface is elastically retracted into the bracket perpendicular to the axial direction, while the gripping element is pushed through the part and the support element until the clamp completely passes through the support element. Clamping surface resiliently returns to position on the clamp outer side to take the clamping position for pressing against the support element, when the gripping element is in the fully pressed position. Fastening device further includes the correct assembly indicator, which has the form of a pin, which is axially pressed into the bracket. Indicator and bracket are made so, that when the gripping element is pushed through the support element, the indicator can not be axially pushed into the bracket with support to the gripping element; at the same time, it is necessary, that the indicator was elastically retracted perpendicular to the axial direction to the clamp inner side under the clamping surface action, which retreats to the clamp inner side, which allows the indicator complete pressing into the clamp, only when the gripping element clamping side is completely in the clamping position for the support element clamping from behind.

EFFECT: disclosed is the clamping device.
