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 all belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1, the deformed steel bar connecting sleeve convenient to mount in this embodiment includes a connecting column 1, and two ends of the connecting column 1 are respectively provided with a connecting structure in threaded connection with end portions of two deformed steel bars 10; the two connecting structures both comprise a limiting bolt 3 and a connecting sleeve 2 with one closed end; the closed end of the connecting sleeve 2 is provided with a through hole 21, and a ring body 22 is formed at the closed end; the end part of the connecting column 1 is provided with a threaded hole 11, the end part of the connecting column 1 is inserted into the through hole 21, a screw rod of the limiting bolt 3 is connected with the threaded hole, and the ring body 22 is limited by a bolt head of the limiting bolt 3 and can still rotate on the limiting bolt; the side wall of the inner hole of the connecting sleeve 2 is provided with an internal thread, and the end part of the threaded steel bar 10 is inserted into the inner hole of the connecting sleeve 2 and then is in threaded connection with the internal thread. The length of the connecting column can be designed into the length that the closed ends of the two connecting sleeves can be tightly attached together, or the length that a space exists between the closed ends of the two connecting sleeves. Wherein can be with the length design of spliced pole for making the blind end of two adapter sleeves can hug closely the length together, and after adapter sleeve and twisted steel threaded connection, weld between adapter sleeve and the twisted steel, also weld after the blind end laminating of two adapter sleeves. In the process that the connecting sleeve rotates, the internal thread of the connecting sleeve is utilized to enable the thread of the threaded steel bar to gradually displace and be in threaded connection with the threaded hole of the connecting sleeve for fixing.
In this embodiment, when the screw of the limiting bolt 3 is screwed with the threaded hole 11 and then is located inside the connecting sleeve 2, only the limiting bolt of the hexagon socket limiting bolt or the cross-grooved bolt head can be adopted, so that the hexagon socket screwdriver or the cross-grooved bolt can conveniently perform threaded connection for screwing the limiting bolt.
