In order to solve the problems of the technologies described above, the utility model provides a kind of without the tight wall-through pull rod of screw thread self-locking, of the present utility modelly can realize substituting screw rod with plain bars without the tight wall-through pull rod of screw thread self-locking, thus it is convenient and through walls without the need to using the object of PVC sleeve pipe to realize drawing materials, and structure simple, remove convenient, the number of turnover is large.
The utility model in order to the technical scheme solving its technical problem and adopt is:
A kind of without the tight wall-through pull rod of screw thread self-locking, by to pull bar, L shape fixture, fixed leg, hold-down nut, cored screw and to drawing nut to form, described L shape fixture has the horizontal stator and longitudinal stator that intersect vertically, described longitudinal stator offers the first perforation, described horizontal stator offers fixed leg perforation, the upper semisection of described fixed leg offers the second perforation and lower semisection has screw thread, described cored screw has external screw thread, described one end to pull bar is fixed with limited block, described to drawing nut to twist in described cored screw, described cored screw is placed on described one end to pull bar and stops by described limited block, described fixed leg is through in the fixed leg perforation of L shape stator, hold-down nut is twisted in fixed leg lower end, described to first perforation of the pull bar other end through L shape stator and the second perforation of fixed leg, tighten hold-down nut to make to fix the other end of pull bar, rotate drawing nut with tension to pull bar to the other end of pull bar.
The utility model in order to the further technical scheme solving its technical problem and adopt is:
Say further, described to drawing nut to be plateau nut.
It is preferred that described limited block is one section of reinforcing bar of the one end be welded in pull bar, make to form T connector to one end of pull bar.
It is preferred that described to drawing nut to be hex nut.
It is preferred that described hold-down nut is hex nut.
Say further, described is plain bars to pull bar.
The beneficial effects of the utility model are: of the present utility model without the tight wall-through pull rod of screw thread self-locking by pull bar, L shape fixture, fixed leg, hold-down nut, cored screw and to drawing nut to form, during use, first will twist on cored screw to drawing nut, then cored screw is placed on to pull bar one end, hold-down nut is twisted in fixed leg lower end, fixed leg is through in the fixed leg perforation of L shape fixture, make L shape fixture by wall, insert in the first perforation of L shape fixture and the second perforation of fixed leg successively after through walls to pull bar again, and cored screw is slid into be subject to the stop of the limited block to tie rod end, then hold-down nut is tightened to make to fix the other end of pull bar, finally by drawing nut to reach the object of tension to pull bar towards rotating the other end of pull bar.Of the present utility modelly can realize substituting screw rod with plain bars without the tight wall-through pull rod of screw thread self-locking, thus it is convenient and through walls without the need to using the object of PVC sleeve pipe to realize drawing materials, and structure simple, remove convenient, the number of turnover is large.
