Abstract
The invention discloses a kind of tensioning latch fitting, including tensioning lock, steel pole and locking nut, the left and right ends of the tensioning lock open up U-shaped mounting groove, limited block is fixedly installed in one end of the steel pole, the steel pole is to set locking nut on screw thread steel pole, the steel pole, and the steel pole is placed in mounting groove, and limited block is located on the inside of tensioning lock, the locking nut is located at the outside of tensioning lock.It the advantage is that：The tensioning latch fitting that the present invention is obtained, steel pole need to only be prevented in mounting groove, be fixed by the limited block and locking nut of both sides, from installing for structure, install very convenient, simultaneously for being used in parallel conveniently for track, save substantial amounts of labour.
Description
Technical field
The present invention relates to tensioning equipment technical field, more particularly to a kind of tensioning latch fitting.
Background technology
For the high speed development of present railway so that need to put into largely on railway production with building, the construction of track
It is to need the hair plenty of time to go to build for a long time, wherein parallel track is a very important link, for the tensioning lock used
Part is complicated, in-convenience in use, considerably increase labour.
The content of the invention
It is an object of the invention to provide a kind of tensioning latch fitting simple in construction, easy to use.
The technical solution adopted by the present invention is：
A kind of tensioning latch fitting, including tensioning lock, steel pole and locking nut, its innovative point are：The left and right ends of the tensioning lock
U-shaped mounting groove is opened up, limited block is fixedly installed in one end of the steel pole, and the steel pole is to be set on screw thread steel pole, the steel pole
Locking nut is put, the steel pole is placed in mounting groove, and limited block is located on the inside of tensioning lock, the locking nut is located at tensioning
The outside of lock.
Further, the limited block is that fixation is set inside square structure, the tensioning lock of the both sides up and down of the limited block
Put fixture block.
Beneficial effects of the present invention are as follows：
The tensioning latch fitting that the present invention is obtained, steel pole need to only be prevented in mounting groove, pass through the limited block and locking nut of both sides
It is fixed, from installing for structure, installs very convenient, simultaneously for being used in parallel conveniently for track, saves big
The labour of amount.
