Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures, in particular to a fixture structure for locking with double external thread bolts. Background Art

[0002] Double external thread bolt is a common fastener, mainly used to connect or fix two parts. Its characteristic is that there are threads on both ends of the bolt, so it can be tightened in two directions at the same time, thus providing better stability and support. This kind of bolt is usually used in occasions that need to withstand large tensile forces, such as bridge construction, heavy machinery, etc.

[0003] The locking method of some existing double external thread bolts is to machine a flat surface on the round rod section of the bolt and clamp and lock it with a wrench. This is very inconvenient when the space is small, and the material removal of the machined surface will reduce the strength of the bolt. Another method is to use two nuts to tighten the threads. When rotating the nuts, in most cases, only an ordinary internal clamping wrench can be used for operation, and disassembly and assembly are very time-consuming.

[0004] Therefore, a fixture structure for locking with double external bolts is proposed. Utility Model Content
