The invention discloses a tensile anti-rotation sealing riveting stud for holes. The tensile anti-rotation sealing riveting stud mainly consists of a stud rod, a stud cap and an anti-rotation pin; the front end of the stud rod is arranged to be a frustum; the stud cap is arranged at the frustum on the stud rod in a sleeved way; the outer side of the stud cap is provided with tensile teeth; a pin hole is formed in the side wall of the stud cap; the anti-rotation pin is arranged in the pin hole; a pin slot corresponding to the pin hole is formed in the frustum; the rear end of the anti-rotation pin is located in the pin slot; and the front end face of the anti-rotation pin is provided with anti-rotation teeth. The tensile anti-rotation sealing riveting stud disclosed by the invention has the advantages the tensile anti-rotation sealing riveting stud for the holes is fixedly installed in manner of pull riveting, and is very rapid and convenient to install; not only can the riveting stud be effectively prevented from separating from an installing hole but also the riveting stud can be effectively prevented from rotating in the installing hole.
Description
technical field [0001] The present invention relates to the technical field of connectors, more specifically to the technical field of connecting studs. Background technique [0002] In people's daily production and life, it is often necessary to use connectors with studs to fix various parts or devices on electrical equipment, mechanical equipment or walls and floors. At present, the commonly used connectors are mostly expansion bolts or rivets. Bolts, etc., when using this type of connecting piece for installation and fixing, first open a mounting hole on the base, place the rear end of the connecting piece in the mounting hole, use a riveting gun and other instruments to permanently fix the rear end of the connecting piece on the In the installation hole, then install the parts or devices to be installed on the studs at the front end of the connector. This method of fixing with expansion bolts or rivet bolts is not very reliable. If the load is large or there is a large ...
