Therefore, a self-contained extension type rust-proof bolt is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a from taking rust-resistant bolt of extension type to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a self-contained elongated rust-proof bolt comprises a first bolt rod, a second bolt rod and a third bolt rod, the upper end surface of the first bolt rod is integrally connected with a bolt head, the upper end surface of the third bolt rod is integrally connected with a connecting bolt rod, the lower end surface of the first bolt rod is provided with a connecting threaded hole for connecting the connecting bolt rod in a threaded manner, a circular through hole for the connecting bolt rod to pass through is formed in the middle of the second bolt rod, a positioning column is fixedly connected to the upper end face of the second bolt rod and is positioned on the outer ring of the circular through hole, a positioning hole for inserting the positioning column is formed in the lower end face of the first bolt rod and is positioned on the outer ring of the connecting threaded hole, the lower end of the outer side of the connecting bolt rod is fixedly connected with a screw cap, and the surfaces of the first bolt rod, the second bolt rod, the third bolt rod, the bolt head and the connecting bolt rod are all provided with wear-resistant and rust-proof layers.
As a further optimization of the present technical solution, the first bolt bar, the second bolt bar and the third bolt bar have the same diameter.
As the further optimization of the technical scheme, the positioning columns and the positioning holes are all provided with three groups, and the positioning columns and the positioning holes are circumferentially distributed at equal intervals.
As a further optimization of the present technical solution, the length of the connecting bolt rod is longer than the length of the second bolt rod.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can adjust the length of bolt for three kinds of length, convenient to use can be adjusted according to the demand to the bolt. Inserting the positioning column into the positioning hole, then enabling the connecting bolt rod to penetrate through the circular through hole and be in threaded connection with the connecting threaded hole, and further enabling the first bolt rod, the second bolt rod and the third bolt rod to be connected, so that the bolt reaches the maximum length; directly connecting the connecting bolt rod with the connecting threaded hole in a threaded manner, so that the first bolt rod and the third bolt rod can be fixedly connected, and the bolt can reach a medium length; the first bolt shank is used directly alone so that the bolt reaches the shortest length.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a self-contained elongated rust-proof bolt comprises a first bolt rod 1, a second bolt rod 2 and a third bolt rod 3, wherein the diameters of the first bolt rod 1, the second bolt rod 2 and the third bolt rod 3 are the same, threads among the first bolt rod 1, the second bolt rod 2 and the third bolt rod 3 are continuous, and threads among the first bolt rod 1, the second bolt rod 2 and the third bolt rod 3 are also continuous. The integrated into one piece of 1 up end of first shank of bolt is connected with bolt head 4, 3 up end integrated into one piece of third shank of bolt is connected with connecting shank of bolt 5, connecting threaded hole 6 that is used for threaded connection connecting shank of bolt 5 is offered to 1 lower terminal surface of first shank of bolt, circular through-hole 7 that supplies connecting shank of bolt 5 to pass is offered at 2 middle parts of second shank of bolt, and is concrete, the length of connecting shank of bolt 5 is longer than the length of second shank of bolt 2, make install second shank of bolt 2 between first shank of bolt 1 and third shank of bolt 3 after, connecting shank of bolt 5 still can with connecting threaded hole 6 threaded connection. 2 up end of second bolt pole and being located 7 outer lane fixedly connected with reference column 8 of circular through-hole, 1 lower terminal surface of first bolt pole and being located 6 outer lanes of connecting thread hole and offering the locating hole 9 that is used for pegging graft reference column 8, reference column 8 and locating hole 9 all set up three groups, three equal circumference equidistance distributions of reference column 8 and locating hole 9 of group, 5 outside lower extreme fixedly connected with screw caps 10 of connecting bolt pole, screw caps 10 play the fastening effect for third bolt pole 3 follows first bolt pole 1 and 2 synchronous rotations of second bolt pole.
