Description
Technical field
The utility model belongs to equipment technique for fixing field, and particularly, the utility model relates to a kind of anticreep threaded fastening device.
Background technique
Existing screw threads for fastening mode many employings screw directly connects, and in the process of dismounting, screw is easily lost, and wastes time and energy during refitting.
Model utility content
The purpose of this utility model is, provide a kind of anticreep threaded fastening device, this device is by rational structural design, fastening piece is installed to after on fixed block, fastening piece can not Automatic-falling, then by fastening piece by fastening for different fixed blocks, dismounting and install all very convenient again.
For achieving the above object, the utility model have employed following technological scheme:
A kind of anticreep threaded fastening device, described device comprises fastening piece 1, first fixed block 2, and described fastening piece 1 comprises part cap 11, intermediate bar 12 and end 13, and described end 13 arranges outside thread, and the diameter of described intermediate bar 12 is less than the diameter of end; In the middle of described first fixed block 2, through hole 21 is set, in described through hole 21, establishes the internal thread matched with outside thread.
Further, described device also comprises the second fixed block 3, and described second fixed block 3 arranges mounting hole 31, establishes the internal thread matched with outside thread in described mounting hole 31.
Preferably, described through hole 21 is step hole.
Diameter due to intermediate bar 12 is less than the diameter of end, and the end outside thread of fastening piece 1 described in the utility model is screwed into the through hole internal thread of the first fixed block 2, and when outside thread is screwed into completely, intermediate bar 12 is in through hole in free movement state.
The end of fastening piece 1 of the present utility model, through after the first fixed block 2, is continued the mounting hole 31 being screwed into the second fixed block 3, the first fixed block and the second fixed block can be fixed together.
The utility model structure is simple, easy for installation.
During the utility model dismounting, fastening piece and the second fixed block are turned on, and such fastening piece can not throw off the first fixed block, prevents fastening piece from losing.
