REINFORCED FASTENER Russian patent published in 2018 - IPC F16B21/00 F16B39/00 H05K7/02 

FIELD: machine building.

SUBSTANCE: invention relates to a fastener used for fixing electronic equipment, and can be used in instrumentation to ensure the attachment of devices to a supporting wall. Technical result is achieved by the fact that the fastener includes: a catcher link with a blind axial threaded hole at one end having two sections: the first from the entrance to the hole is smooth, the second threaded, from the other end there is an axial threaded rod on the bushing fastening the bushing-catcher to the wall, and in the place of attachment to the wall, the catcher-link has an enlarged diameter, as well as eyelets with holes located near the axial threaded rod. Catcher link has areas with a diameter increasing from the side of a blind axial threaded hole: the first cone, cylindrical, the second cone - with a stepless transition of one into another. Fastener also includes a housing element of the device with a protrusion in which a cylindrical cavity corresponding to the diameter of the cylindrical portion of the catcher-link is formed, along the axis of the cylindrical cavity a through threaded hole corresponding to the blind axial threaded hole in the catching sleeve is formed, and a captive screw with a conical end that has a thread corresponding to the through-threaded hole in the cylindrical protrusion cavity in the body element of the device and the blind axial threaded hole in the bushing, spring-loaded by the spring onto the captive screw. In this case, the safety catch and the captive screw are located in the cylindrical cavity of the protrusion of the housing element.

EFFECT: technical result is to provide simultaneous convenience of mounting / dismantling of the device, reliability of its attachment, ability to withstand large static and dynamic loads and save space in the installation.
