Abstract

The invention discloses a rear fastener mechanism, and belongs to the technical field of mechanical parts. The rear fastener mechanism comprises a fastener body, wherein a threaded hole is formed inside the fastener body, a sealing piece accommodating cavity is formed in the bottom of the threaded hole, a threaded telescopic rod is in threaded connection with the interior of the threaded hole, anda sealing piece sleeve rod is fixedly connected to one end of the threaded telescopic rod. According to the rear fastener mechanism, the fastener body, a sealing gasket, the threaded telescopic rod and an gas injection hole are matched for use, after a worker places the fastener body behind a container, the sealing gasket can be pushed from the fastener body by screwing the threaded telescopic rod, then air pressure is supplied to the sealing gasket through the gas injection hole, the fastener body is inflated after gas enters the sealing gasket, then the fastener body is affixed to the innerwall of a hole of the container, the rear fastener mechanism not only improves the overall sealing performance, but also improves the firmness of a fastener, and the loosening phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a rear fastener mechanism. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide range of varieties and specifications, different performances and uses, and the degree of standardization, serialization, and generalization is also extremely high. [0003] In the prior art, the fastener does not permanently seal the container, and the user can still open the container without destroying the fastener, but after the fastener is placed on the container, the liquid in the container is very It will flow out along the connection gap between the container and the fastener, thereby reducing the airtightness ...
