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...

Abstract

The invention belongs to the technical field of construction and relates to a double-ended screw connection structure. It includes a double-ended nut, and the double-ended nut includes a reinforcing rod and a nut body arranged coaxially. There are two nut bodies and they are respectively fixed at both ends of the reinforcing rod. When the nut is on both sides, one of the nut bodies of the double-ended nut is screwed with one of the objects to be connected, and the double-ended nut is turned to make the other nut body screw with the other object to be connected so that the two nut bodies are respectively It is screwed and fixed with two objects to be connected. The invention can be used for the connection between two objects, the connection distance between the two objects is adjustable, the assembly is convenient, the connection is convenient, and the connection is firm and reliable without loosening.

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...
