Abstract
The invention discloses a debris storage self-tapping self-locking dual-thread sleeve. The sleeve mainly comprises a cylindrical body. A through hole is formed in the body along the axis, threads are arranged on the inside and the outside of the through hole of the body respectively, debris storage grooves are formed in the outside surface of the body and are in the ends of the body. The sleeve has the advantages that all adverse effects and results produced by falling of wires are prevented completely, the workload of cleaning of fallen wires during working is omitted, and accordingly, the mounting working efficiency is improved effectively; a certain anti-loosening self-locking function is provided, so that the fastening performance during mounting is improved greatly.
Description
Technical field
The present invention relates to the technical field of fastening piece, more particularly relate to the technical field of two thread bush.
Background technique
Two thread bush is mainly used for needing to play certain reinforing function when fixing other component on the parts that material is softer.It is widely used on Aeronautics and Astronautics and train high speed motor car, at present, particularly use especially extensive on the high speed motor car of train, due in design in order at utmost alleviate the weight of motor-car itself, the housing of locomotive adopts aluminum material to be made usually, but because the material of aluminum material own is partially soft, if desired thereon other component fastening time, its fastening strength will be difficult to ensure.Current solution is first holed on aluminum material, again two thread bush is embedded in by screw thread in the hole of having bored in advance, by embedding two thread bush in it and other component are effectively fastenedly connected, still have the following disadvantages in current using process, one is that existing pair of thread bush rear latch-up-free device in advances through hole easily loosens backed off after random, causes potential safety hazard; Two be existing pair of thread bush in advances through hole time can be attended by wire produce, after the wire of this generation drops out in through hole, must clean out separately, if the wire produced cannot drop out in hole, bring inconvenience also can to follow-up work, even can have influence on the normal mounting of follow-up component.
Summary of the invention
Object of the present invention is exactly provide a kind of structural design very reasonable to solve above-mentioned deficiency, lockingly can have auto-lock function, and can not be attended by the storage bits formula self-tapping self-locking pair thread bush that wire drops out.
The technical solution that the present invention adopts to solve the problems of the technologies described above is as follows:
The two thread bush of storage bits formula self-tapping self-locking, it is formed primarily of cylindrical main body, and this main body offers through hole along its axis, and in the through hole of main body, outside is respectively arranged with screw thread, the described outer surface being positioned at main body offers nail collection slot, and this nail collection slot is positioned at the end of main body.
The cross section of described nail collection slot is L-shaped, and nail collection slot one end that this cross section is L-shaped is provided with cutting edge.
Described nail collection slot forms by 2 to 5, and is uniformly distributed the end be positioned at outside main body by same direction.
The described body end being positioned at nail collection slot one end is provided with directional post.
The length of described directional post is 1 to 3 millimeter.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: by offering nail collection slot in the outboard end of two thread bush, in use, the wire supervened can directly enter in this nail collection slot, and can not outwards spill, all adverse effects of producing because wire drops out and consequence will be avoided so completely, cleaning is needed to drop out workload wiry when also eliminating work, effectively improve the working efficiency of installation, in addition, through well-designed nail collection slot structure after storage wire, under the effect of wire and nail collection slot, also be provided with certain locking auto-lock function, substantially increase fastening performance during installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A sectional structure schematic diagram of Fig. 1;
Fig. 3 is the complete section structural representation of Fig. 1.
Embodiment
By Fig. 1, shown in Fig. 2 and Fig. 3, the two thread bush of storage bits formula self-tapping self-locking, it is formed primarily of cylindrical main body 1, this main body 1 offers through hole 2 along its axis, in the through hole 2 of main body 1, outside is respectively arranged with screw thread 3, screw thread 3 direction in this interior outside is consistent, the described outer surface end opens being positioned at main body 1 has nail collection slot 4, the cross section entirety of this nail collection slot 4 is L-shaped is advisable, overall L-shaped nail collection slot 4 one end of this cross section is provided with cutting edge 5, to reduce turn resistance when two thread bush uses, this nail collection slot 4 forms by 2 to 5, and the end be positioned at outside main body 1 is uniformly distributed by same direction, conveniently in use, two thread bush can screw in tram and direction, main body 1 end being positioned at nail collection slot 4 one end is provided with directional post 6, the length of this directional post 6 is 1 to 3 millimeter and is advisable.
Claims (5)
1. store up the two thread bush of bits formula self-tapping self-locking, it is characterized in that: it is formed primarily of cylindrical main body, this main body offers through hole along its axis, in the through hole of main body, outside is respectively arranged with screw thread, the described outer surface being positioned at main body offers nail collection slot, and this nail collection slot is positioned at an end of main body.
2. the two thread bush of storage bits formula self-tapping self-locking according to claim 1, is characterized in that: the cross section of described nail collection slot is L-shaped, nail collection slot one end that this cross section is L-shaped is provided with cutting edge.
