Abstract
The utility model is the technical field of locks, and discloses a theft-proof lock. The main feature of the theft-proof lock is that a fixed block is arranged on the inner ring of the top part of a U shape lock ring. Two inclined surfaces are arranged on the end surface of the fixed block, and the end surface is provided with a clamping slot special purpose nut. A special purpose nut is arranged on the thread of the ring pole of the U shape lock ring. A clamping slot is arranged on a lock body, and is used for fixing a distaff and the anti-sawing device of the distaff on the lock body. The lock body, the lock ring, etc. Of the theft-proof lock are specially treated, and can not be sawed off by a hacksaw. The two inclined surfaces on the end surface of the special purpose nut can control the special purpose nut to rotate only according to a thread tightening direction, and the special purpose nut can not be backed out. The theft-proof lock has stable and reliable tightening, and convenient use.
Description
Technical field:
The utility model belongs to lock technology field, is specifically related to a kind of lock.
Background technique:
Existing distaff and the distaff Sawing-resistant theft-proof device that is used for the supporting electric wire bar need tighten together, and do not stolen by saw thereby protect distaff, can prevent to cause the generation of the accident of falling the rod disconnection.Existing distaff and the fastening of backguy Cou Sawing-resistant theft-proof device are that the two is welded together, owing to should be fastening be execute-in-place in the open air, need to carry equipment such as electric welding machine, complicated operation, take a lot of work, time-consuming.
Summary of the invention:
The purpose of this utility model is that design is a kind of easy to use, is fit to the fastening lock of field condition.
For achieving the above object, the technological scheme that the utility model adopted is existing U type to be worn the bar lockset improved, and has additional fixed block, special-purpose nut, the fixed block outside is provided with draw-in groove, is installed on to encircle in the lock ring top, the inside of fixed block is provided with draw-in groove, is used to clamp the distaff Sawing-resistant theft-proof device.Special-purpose nut is contained on the screw thread of lock ring annulated column, and special-purpose nut exterior edge face is provided with the inclined-plane, the direction rotation that this inclined-plane control specialized nut can only tighten along the screw thread of lock ring post.And on lock body, be provided with draw-in groove, be used to clamp the line-transect rod.Thereby constitute a kind of lock.
The lock that adopts such scheme to make, its lock body, lock ring etc. are to reach higher numerical value through its intensity hardness of special processing, and the use hacksaw can't be sawed-off.And special-purpose nut can only tighten direction rotation according to screw thread, and can not reverse, and when using this lock that distaff and distaff Sawing-resistant theft-proof device are locked together, can't dismantle again.Compared with prior art, have fastening reliable and stable, easy to use, saving of work and time, advantage such as cheap.
The utility model is described in further detail to reach example in conjunction with the accompanying drawings.
