Abstract
The utility model discloses a kind of circular groove type bolt-couple against loss, comprise bolt and plain nut, bolt is connected with plain nut internal and external threads, is provided with tightening nut outside described plain nut, intermittently to coordinate in described tightening nut without screw thread with bolt; The screw section of bolt has outer annular groove, and in tightening nut, radial direction has interior circular groove, and interior circular groove is identical with outer annular groove size; Have the inclined hole that connect round and smooth with interior circular groove outside described tightening nut, inclined hole is provided with steel wire; The utility model structure is simple, easy to install, and steel wire clamping is also looped around in inside-and-outside ring groove and blocks moving up and down of tightening nut, reaches good anti-theft effect.
Description
Technical field
The utility model relates to a kind of fastening piece, especially relates to a kind of circular groove type bolt-couple against loss.
Background technique
Bolt is a kind of conventional part, can be widely used in the occasion that various needs are fixing.The bolt of prior art by having the screw rod of screw head, nut forms, this bolt spanner is very easy to dismounting, in some machinery, as the fields such as electric power facility, track traffic, automobile making, steel building facility all need to be bolted fixing, if adopt bolt to install, easily be disassembled so be easy to stolen because of bolt, cause economic loss.
Model utility content
In order to overcome above-mentioned existing technological deficiency, it is simple, easy for installation that the purpose of this utility model is to provide a kind of structure, the circular groove type bolt pair of good anti-theft effect.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of circular groove type bolt-couple against loss, comprises bolt and plain nut, and bolt is connected with plain nut internal and external threads, is provided with tightening nut outside described plain nut, intermittently to coordinate in described tightening nut without screw thread with bolt; The screw section of bolt has outer annular groove, and in tightening nut, radial direction has interior circular groove, and interior circular groove is identical with outer annular groove size; Have the inclined hole that connect round and smooth with interior circular groove outside described tightening nut, inclined hole is provided with steel wire.Plain nut plays fixation when installing and using; Outside plain nut, tightening nut is installed, interior circular groove on tightening nut and the outer annular groove on bolt coordinate and are in same position, steel wire enters interior circular groove and outer annular groove through inclined hole, steel wire clamping is also looped around between interior circular groove and outer annular groove and prevents moving up and down of tightening nut, is formed antitheft.
As optimization, described interior circular groove and outer annular groove are all semicircle or square, and interior circular groove and outer annular groove are all semicircle, the convenient processing of semi-circular groove, and what be beneficial to when steel wire inserts is smooth and easy simultaneously.
As optimization, described interior circular groove and the width of outer annular groove and the degree of depth are all less than thread pitch, while ensureing anti-theft effect, guarantee the firm of bolt pair.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, easy to install, and steel wire clamping is also looped around in inside-and-outside ring groove and blocks moving up and down of tightening nut, reaches good anti-theft effect.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is plan view of the present utility model;
Fig. 2 is the structural representation of the utility model bolt;
Fig. 3 is partial structurtes schematic diagram of the present utility model.
Mark in figure: bolt 1, plain nut 2, tightening nut 3, inclined hole 4, interior circular groove 5 and outer annular groove 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in Figure 1, Figure 2 with shown in Fig. 3, the utility model is a kind of circular groove type bolt-couple against loss, comprise bolt 1 and plain nut 2, bolt 1 is connected with plain nut 2 internal and external threads, outside described plain nut 2, tightening nut 3 is installed, intermittently coordinates with bolt 1 without screw thread in described tightening nut 3; The screw section of bolt 1 has outer annular groove 6, and in tightening nut 3, radial direction has interior circular groove 5, and interior circular groove 5 is identical with outer annular groove 6 size; Have the inclined hole 4 that connect round and smooth with interior circular groove 5 outside described tightening nut 3, inclined hole 4 is provided with steel wire.Plain nut 2 plays fixation when installing and using; Tightening nut 3 is installed outside plain nut 2, interior circular groove 5 on tightening nut 3 and the outer annular groove 6 on bolt 1 coordinate and are in same position, steel wire enters interior circular groove 5 and outer annular groove 6 through inclined hole 4, steel wire clamping is also looped around between interior circular groove 5 and outer annular groove 6 and prevents moving up and down of tightening nut 3, is formed antitheft.
Embodiment 2, and on the basis of embodiment 1, internal circular groove 5 and outer annular groove 6 make optimal design, and described interior circular groove 5 and outer annular groove 6 are all semicircle or square, the convenient processing of semi-circular groove, and what be beneficial to when steel wire inserts is smooth and easy simultaneously.
Embodiment 3, and on the basis of embodiment 1, internal circular groove 5 and outer annular groove 6 make optimal design, and described interior circular groove 5 and the width of outer annular groove 6 and the degree of depth are all less than thread pitch, while ensureing anti-theft effect, guarantee the firm of bolt pair.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
