Problems solved by technology
However, this solution needs to assemble the intermediate nut, elastic member, and snap ring at one time during assembly, and the assembly of the snap ring needs to be careful, otherwise it will easily cause the snap ring to fall and fail to achieve docking, so the connection is not fast and convenient.
[0004] In summary, the above-mentioned solution is not convenient enough to use the elastic plug-in connection method, especially when connecting two objects with threaded structures, the connection of the connecting piece is relatively inconvenient

Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 As shown, a double-ended screw connection structure includes a double-ended nut 1, and the double-ended nut 1 includes a reinforcing rod 2 and a nut body 3 coaxially arranged. The nut in the prior art does not have a reinforcing rod 2, When the two ends are respectively connected to an object, if misalignment occurs, the nut will easily crack and cause the connection to fail. When the object connected by the stud nut 1 moves, the reinforcing rod 2 can absorb the bending force and prevent the stud nut 1 from cracking , so the reinforcing rod 2 plays the role of anti-bending and improving the firmness of the stud nut 1, and is suitable for buildings with high requirements for earthquake resistance.
[0025] Such as image 3 As shown, there are two nut bodies 3 and they are respectively fixed at both ends of the...

The invention belongs to the technical field of buildings, and relates to a double-end screwing type connecting structure. The structure comprises a double-end nut, wherein the double-end nut comprises a reinforcing rod and nut bodies coaxially arranged; two nut bodies are provided, and are respectively fixed at the two ends of the reinforcing rod; when two objects to be connected are put at the two sides of the double-end nut, one nut body of the double-end nut is screwed with one object to be connected; and the double-end nut rotates to enable the other nut body to be screwed with the other object to be connected, so that the two nut bodies are respectively screwed and fixed with the two objects to be connected. The double-end screwing type connecting structure can be applied to the connection between two objects, is adjustable in connecting distance of the two objects, is convenient for assembly and connection, and is firm and reliable without loosening after connection.
Description
technical field [0001] The invention belongs to the technical field of construction and relates to a double-ended screw connection structure, which is suitable for the connection between two objects. Background technique [0002] The applicant’s previous application for a patented strong tension connection connector [Application No.: 201510314380.0] includes a first tension nut and a second tension nut respectively fixed at both ends of the prefabricated part. The first tension nut can be The insertion rod is disassembled and connected, and the middle nut is detachably connected to the second tension nut. The second tension nut is provided with an elastic member, and a snap ring is arranged between the intermediate nut and the elastic member. When the insertion rod is inserted When entering the middle nut, the snap ring can hold the insertion rod, the middle nut includes a nut body, the outer wall of the nut body has external threads, and the inside of the nut body is provid...
