[0003] The hydraulic nuts currently used can only be used for a single lock ring. To lock different lock rings, different types of hydraulic nuts need to be replaced. The scope of application is small, and corresponding screw sleeves are also required to lock the screw that needs to be stretched. Fix the screw, and the existing hydraulic nut can only fix the corresponding screw. When encountering screws of different sizes, the hydraulic nut also needs to be replaced. The work efficiency is low. There is no protective measure for the bottom of the hydraulic nut. During the pressing process, it may cause crushing damage to the surface of the object to be fastened

Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-Figure 4 As shown, a hydraulic nut according to the present invention includes a nut body 1, a circular groove 2 is opened at the lower end of the nut body 1, a through groove 3 is opened at the upper end of the nut body 1, and the round groove 2 is connected with the through groove 2. The groove 3 is connected, and the inner wall of the circular groove 2 is connected with a locking block 4 through ball rotation, the side wall of the locking block 4 is provided with a locking hole 5, and the right side of the lower end of the nut body 1 is provided with a lock. To tighten the window 6, the inside of the locking block 4 is provided with a movable groove 7, and the inside of the movable groove 7 is slidably connected with an en...

The invention relates to the field of nuts, in particular to a hydraulic nut. The hydraulic nut comprises a nut body, the lower end of the nut body is provided with a circular groove, the upper end ofthe nut body is provided with a through groove, the circular groove communicates with the through groove, the inner wall of the circular groove is rotationally connected with a locking block througha ball, the side wall of the locking block is provided with a locking hole, the right side of the lower end of the nut body is provided with a locking window, the inside of the locking block is provided with a movable groove, a clamping block is in sliding connection with the interior of the movable groove, a first locking groove is formed in the lower end of the interior of the clamping block, asecond locking groove is formed in the upper end of the first locking groove, and a third locking groove is formed in the upper end of the second locking groove. By providing the first locking groove,the second locking groove and the third locking groove, locking rings in three different sizes can be locked by using the first locking groove, the second locking groove and the third locking groove,the application range of the hydraulic nut is increased when the hydraulic nut is used by people, and use by the people is facilitated.
Description
technical field [0001] The invention relates to the field of hydraulic nuts, in particular to a hydraulic nut. Background technique [0002] The hydraulic nut is an advanced bolt assembly method, especially suitable for tight spaces and heavy-duty vibrating mechanical fastening. The working principle of the hydraulic nut is to use the hydraulic cylinder to directly apply an external force to the bolt, so that the applied bolt is elongated in its elastic deformation zone, and after the bolt is elongated, tighten the lock ring on the hydraulic nut, so that the bolt will be locked. The ring locks in the elongated position. [0003] The hydraulic nuts currently used can only be used for a single lock ring. To lock different lock rings, different types of hydraulic nuts need to be replaced. The scope of application is small, and corresponding screw sleeves are also required to lock the screw that needs to be stretched. Fix the screw, and the existing hydraulic nut can only fix ...
