Abstract

The invention discloses a unidirectionally-installed bolt assembly which comprises a member where an installation hole is previously arranged, a bolt, an irregular nut and a swinging part. The irregular nut is matched with the bolt in a screw fit mode and can penetrate through the installation hole, the swinging part can penetrate through the installation hole and abuts against the lower side of the installation hole, the swinging part is installed on the irregular nut in a rotating mode, the irregular nut is in screw fit on the bolt, the bolt penetrates through the installation hole to enable the swinging part and the irregular nut to penetrate through the installation hole to be arranged on the lower side of the installation hole, the bolt is pulled to enable the swinging part to abut against the lower side of the installation hole, and the bolt is rotated until the bolt and the irregular nut are screwed tightly. The bolt assembly is simple in structure, a few in parts, low in cost, suitable for arbitrary members of closestools and the like which can be installed unidirectionally and convenient to use and install.

Description

technical field [0001] The present invention relates to unidirectional mounting bolt assemblies. Background technique [0002] The bolt assemblies currently on the market, such as the bolt assemblies used on toilets, mainly include bolts and nuts. During installation, the nuts or nuts need to be clamped on one side, and the nuts or nuts should be tightened from the other side with a wrench. In general, the installer has access to both sides of the object being fastened. However, for special applications, such as a structure with one end closed or a structure that is not easily accessible, the use of ordinary bolts is greatly restricted. [0003] Or, if the China Invention Patent Authorization Announcement No. is CN100482959C, and the patent title is "a kind of one-way bolt fastener and its assembly method", its nut is made up of two half-rings connected with a short shaft between the half-rings. Although the bolt fastener is one-way, it needs to rely on installation tools,...
