fig. 4 is a schematic structural diagram at B in fig. 3.

In the figure: 1. the handle comprises a nut 2, an internal thread 3, a retaining assembly 3a1, an end plate 3a2, a spring 3a3, a clamping block 3a4, a ratchet 3a5, a handle groove 3a6, a pin shaft 3a7, a clamping groove 4 and a nylon ring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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 without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a sealed locking rust-resistant stopping nut, includes nut 1 and internal thread 2, and the inner wall top internally mounted of nut 1 has nylon ring 4, and the below of nylon ring 4 is provided with stopping subassembly 3.

Referring to fig. 1-4, the present invention provides a retaining assembly 3, which includes an end plate 3a1, a spring 3a2, a latch 3a3, a ratchet 3a4, a handle slot 3a5, a pin shaft 3a6 and a latch 3a7, wherein the end plate 3a1 is respectively located at two upper sides inside the nut 1, one side of the end plate 3a1 is rotatably connected to the nut 1 through the pin shaft 3a6, the other side of the end plate 3a1 is respectively processed with a handle slot 3a5, the elastic coefficient of the spring 3a2 is determined according to specific use conditions, the spring 3a2 is a spiral spring, the latch 3a7 is processed inside the end plate 3a1, the latch 3a3 is stored inside the latch 3a7, the inner side of the latch 3a3 is fixedly connected to the inner side of the inner wall of the latch 3a4, the outer wall of the latch 3a6 is provided with the spring 3a2, two sides of the end plate 3a2 are respectively connected to the nut 3a1 and the nut 3a 364, and the nylon ring are respectively attached to the upper and the lower sides of the nut 364, the end plate 3a1, the pin shaft 3a6 and the handle groove 3a5 are distributed in the nut 1 in a central symmetry manner, and the inner wall of the nut 1 is provided with an internal thread 2;

through the cooperation between ratchet 3a4, end plate 3a1, draw-in groove 3a7, fixture block 3a3 and spring 3a2, along with long-term use back, ratchet 3a4 can wear and tear constantly and lead to appearing the direction rotation that can't block the inserted bar that has corresponding ratchet structure easily, consequently user's accessible handle groove 3a5 drives end plate 3a1 and rotates, make end plate 3a1 drive fixture block 3a3 and rotate out from the inner wall department of nylon ring 4 and nut 1, take out fixture block 3a3 and ratchet 3a4 from draw-in groove 3a7 and change, loosen end plate 3a1 after the completion and can drive it through spring 3a2 and reset, make end plate 3a1 retract the inside of nut 1 again, can't carry out when the stopping ratchet is impaired to be located and can't change the problem that only overall structure can's change.

Principle of operation

When the sealed anti-loose antirust anti-back nut is required to be used, firstly, a user can complete assembly according to the figure, so that an inserted rod with a corresponding ratchet structure is inserted into the nut 1 for corresponding use, the ratchet structure corresponds to the ratchet 3a4 structure, then the nut 1 can be driven to rotate under the clamping action of the ratchet 3a4, the nut 1 is installed at a corresponding position, the sealing of a joint is realized through the nylon ring 4, after the installation is completed, the inserted rod with the corresponding ratchet structure can only be pulled out linearly, the problem that the nut 1 cannot be loosened due to the reverse rotation of the nut 1 in the pulling-out process due to the existence of the ratchet 3a4 is solved, after the long-term use, the ratchet 3a4 can be worn continuously to cause the rotation in the direction that the inserted rod with the corresponding ratchet structure cannot be clamped, and therefore, the user can drive the end plate 3a1 to rotate through the hand groove 3a5, make end plate 3a1 drive fixture block 3a3 and rotate out from the inner wall department of nylon ring 4 and nut 1, take out fixture block 3a3 and ratchet 3a4 from draw-in groove 3a7 and change again, loosen end plate 3a1 and can drive it through spring 3a2 and reset after the change is accomplished, make end plate 3a1 retract the inside of nut 1 again, can't change the problem that only can change overall structure when the stopping ratchet department of having avoided the stopping nut is impaired.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
