The utility model discloses in, can splice extension length with two jib main parts 1, concrete concatenation method is: one end of a first function ring 11 of one boom body 1 (hereinafter, referred to as a first boom body 1) is connected to one end of a third function ring 13 of another boom body 1 (hereinafter, referred to as a second boom body 1), an extension post 14 of the second boom body 1 is inserted into an inner side of a second function ring 12 of the first boom body 1, a third function ring 13 of the second boom body 1 is inserted between the first function ring 11 and the second function ring 12 of the first boom body 1, the insertion post 15 is inserted from an outer side of the first boom body 1, and the insertion post 15 is inserted into a third insertion hole 131 of the third function ring 13 through a first insertion hole 111 of the first function ring 11, thereby completing the splicing of the two boom bodies 1.

Here, the inner diameter of the first functional ring 11 is equal to the outer diameter of the third functional ring 13, the inner diameter of the third functional ring 13 is equal to the outer diameter of the second functional ring 12, the outer diameter of the second functional ring 12 is equal to the outer diameter of the protruding column 14, which is equivalent to that the third functional ring 13 is just inserted into the annular groove formed between the first functional ring 11 and the second functional ring 12, the outer side wall of the third functional ring 13 just abuts against the inner side wall of the first functional ring 11, and the inner side wall of the third functional ring 13 just abuts against the outer side wall of the second functional ring 12; and the outer side wall of the insertion column 15 just props against the inner side wall of the second functional ring 12, so that the connection of the two suspender bodies 1 after splicing is completed cannot shake and is not easy to break and wear.

Of course, the outer diameter of the first function ring 11 is equal to the outer diameter of the boom body 1, and the boom body 1 is a cylindrical member, and the first function ring 11, the second function ring 12, the third function ring 13 and the extending column 14 are all coaxially arranged with the boom body 1, so that the two boom bodies 1 after splicing are still a cylindrical member, and have good bearing capacity in the directions of tension and torsion, and higher stage safety.

Preferably, the suspender body 1 is made of steel integrally formed, so that the suspender body 1 has better capability of bearing stage instruments, can be directly spliced during installation, and has high installation efficiency.

Finally, the length of the projecting studs 14 is greater than the length of the third functional ring 13. That is, the boom body 1 is close to one end of the projecting post 14, and the projecting post 14 is longer than the boom body 1, and similarly, the boom body 1 is close to one end of the first function ring 11, and the recess inside the second function ring 12 is deeper than the recess between the first function ring 11 and the second function ring 12, so that the projecting post 14 of the second boom body 1 is inserted into the second function ring 12 of the first boom body 1 first to complete the alignment of the two boom bodies 1, and then the projecting post 14 of the second boom body 1 is inserted into the second function ring 12 of the first boom body 1 until the third function ring 13 of the second boom body 1 is inserted between the first function ring 11 and the second function ring 12 of the first boom body 1, and finally the second boom body 1 is rotated to align the third insertion hole 131 with the first insertion hole 111, and finally the insertion post 15 is inserted.

The utility model relates to a stage jib structure that can splice's simple structure, two stage jibs can splice extension length, and aim at the convenience when splicing, and the concatenation is efficient, and can guarantee that the stage jib of concatenation after aiming bears stability good, and the security is high.

Embodiment two, still as shown in fig. 1 to 3, only be one of the embodiments of the present invention, on the basis of embodiment one, in the stage suspension rod structure that can be spliced of the present invention, the extending column 14 is provided with the connecting hole 141 for connecting the stage machinery, since the extending length of the extending column 14 is longer, the extending space of the extending column 14 can be used to fix the stage equipment (such as a rope, a protruding rod, etc.), and only the stage equipment and the connecting hole 141 penetrating through the whole extending column 14 need to be connected.

Then, the second function ring 12 is provided with a second insertion hole 121 for facilitating the insertion of the insertion post 15, and the second insertion hole 121 is aligned with the first insertion hole 111, and when the third insertion hole 131 is aligned with the first insertion hole 111, the second insertion hole 121 is located just on the side of the third insertion hole 131 away from the first insertion hole 111 and is aligned with the third insertion hole 131, so that the insertion post 15 can be inserted into the second insertion hole 121 through the first insertion hole 111 and the third insertion hole 131 in sequence.

In addition, the outer side of the insertion column 15 is provided with an external thread 151, and the inner side of the second insertion hole 121 is provided with an internal thread matched with the external thread 151, so that the insertion column 15 can be screwed with the second insertion hole 121, the insertion column 15 is not easy to fall off, and the connection stability is better.

Preferably, the first insertion hole 111 and the third insertion hole 131 are smooth holes, that is, the insertion post 15 is screwed and unscrewed, only the section of the second insertion hole 121 needs to be screwed, and the insertion post 15 can easily pass through the first insertion hole 111 and the third insertion hole 131.

And the depth of the second insertion hole 121 is smaller than the thickness of the second functional ring 12, and the second insertion hole 121 is disposed outside the second functional ring 12, that is, the insertion post 15 does not pass through the second functional ring 12 to reach the inner side of the second functional ring 12, so as to reduce the screwing range of the insertion post 15, and prevent the insertion post 15 from abutting against the outer side wall of the protruding post 14 to cause the wearing of the protruding post 14.

Of course, the number of the first insertion holes 111, the second insertion holes 121, and the third insertion holes 131 may be plural, and the number of the same insertion columns 15 may also be plural, and the two boom bodies 1 are spliced and fixed by the insertion columns 15, as shown in fig. 3, so that the stabilization effect is better.

Finally, the end of the insertion column 15 away from the hanger rod body 1 is provided with a screwing head 152, and the end of the screwing head 152 away from the insertion column 15 is provided with a screwing groove, which can be a straight groove or a cross-shaped groove, etc., so that the insertion column 15 can be screwed by a screwdriver conveniently.

The utility model relates to a stage jib structure that can splice simple structure, extension length can be spliced to two stage jibs, and aim at the convenience during concatenation, and the concatenation is efficient, and can guarantee that the stage jib of splicing after aiming at bears stability good, and the security is high.
