Abstract

The invention relates to an integrative fastener which can be used as an own flat cushion, a spring cushion screw rod and a screw nut, satisfy the requirement on the screw rod and the screw nut in an installation site, avoid influencing installation and firm operation by various conditions or leaking to add the flat cushion and the spring cushion for various conditions, in particular to a situation which is not beneficial to operating, the addition of the flat cushion and the spring cushion wastes time and labor and is dangerous, the flat cushion and the spring cushion are arranged on the screw rod, and a set of combined screw rod parts is formed by matching sizes, the flat cushion and the spring cushion are arranged on the screw nut, an integrative combined screw nut part is formed by the micro-connection of switchable combined points, consequently, the operation difficulty is greatly reduced, and the operation efficiency can be greatly increased.

Description

Technical field [0001] The invention relates to a fastening part - a screw rod and a nut. Background technique [0002] At present, known screw rods and nuts are all separated from flat washers and spring washers. When in use, the installation and fastening operations are often affected by various conditions, or flat pads and spring pads are omitted due to various conditions. Especially, in the occasion of unfavorable operation, it is extremely time-consuming, laborious and dangerous to install flat pads and spring pads. Many on-site operators always hope to be able to attach flat pads and spring pads to the screw rods and nuts, which can not only greatly reduce the difficulty of operation, but also greatly improve the operating efficiency. Therefore, need badly to make a kind of screw rod, nut that carry flat pad, spring pad. Contents of the invention [0003] In order to meet the requirements of the installation site for the screw and the nut, avoid the influence of v...
