Description
Technical field
The utility model relates to a kind of link, is specifically related to a kind of heterotypic bolt that has internal and external threads.
Background technique
Bolt is a kind of one type of fastening piece that is used to be fastenedly connected two component; This traditional bolt need punch respectively on two component when being used for fixing two component, and the screw portion with bolt passes two holes on the component again; Bolt is stretched out the partial fixing in hole with nut; This traditional bolt method is inconvenience very, and the form that installs and fixes is single, can not be suitable for various situation.
Summary of the invention
The purpose of the utility model is: in order to overcome the deficiency of existing technology, the utility model provides a kind of locking to have the heterotypic bolt of internal and external threads easily.
To achieve these goals; Technological scheme below the utility model has adopted: a kind of heterotypic bolt that has internal and external threads, comprise double-screw bolt, described double-screw bolt comprises first double-screw bolt; One end of first double-screw bolt is provided with second double-screw bolt; The side of described second double-screw bolt is provided with outside thread, and described first double-screw bolt is provided with bolt hole away from an end of itself and the second double-screw bolt cooperation place, and the inwall of bolt hole is provided with internal thread.
As preferably, described second double-screw bolt and the coaxial setting of first double-screw bolt.After adopting above-mentioned preferred version, help coaxial being locked at together of fixed block that needs are fixedly connected.
As preferably, the cross-section area of described second double-screw bolt is less than the cross-section area of first double-screw bolt.Adopt above-mentioned select scheme after, more convenient installation.
As preferably, described bolt hole openings place is provided with the nut bore that is connected with bolt hole.Adopt above-mentioned preferred version is arranged after, after the double-screw bolt of the heterotypic bolt that has internal and external threads of the utility model and other parts installed, fix fastening better effects if again with nut.
The heterotypic bolt that has internal and external threads of the utility model comprises first double-screw bolt and second double-screw bolt; Bolt hole in the outside thread on first double-screw bolt and second double-screw bolt can be fixed with part respectively; Thereby it is, simple in structure, convenient and practical with two parts lockings that separate.
