SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Not enough to prior art, the utility model provides an integral type self-locking nut has solved the easy not hard up problem of current nut.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an integral type self-locking nut, includes the main part, the upper end fixed mounting of main part has the shell fragment, the middle part of main part sets up threaded hole, the middle part of screw hole is provided with the dead slot, the connecting hole has been seted up at the middle part of dead slot, the inside of connecting hole is rotated through the gear interlock and is connected with fixing bolt, fixing bolt's the outside is placed in the mounting hole.

Preferably, the number of the elastic sheets is six, and the elastic sheets are symmetrically distributed on the upper end face of the main body.

Preferably, the thread pitch of the upper end and the lower end of the threaded hole is equal.

Preferably, the connecting holes are provided in two numbers and are opened inside the main body.

Preferably, the mounting holes are formed in the inner walls of the middle parts of the two sides of the main body.

(III) advantageous effects

The utility model provides an integral type auto-lock nut. The method has the following beneficial effects:

(1) this integral type self-locking nut through setting up the shell fragment, when main part and fixed body link together, will lead to the fact certain pressure to the shell fragment by fixed object, and then can give main part one thrust to the outside to can prevent that the main part is not hard up.

(2) This integral type self-locking nut through setting up fixing bolt, extrudees it to the inboard of screw hole simultaneously, and then can be with the bolt fastening, and the device has adopted triple fixed, can prevent effectively that the nut is not hard up, and the device simple structure, convenient operation can prevent effectively that the nut is not hard up, is worth using widely.

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 without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an integral type self-locking nut, main part 1, the upper end fixed mounting of main part 1 has shell fragment 2, and threaded hole 3 is seted up at the middle part of main part 1, and threaded hole 3's middle part is provided with dead slot 4, and connecting hole 5 has been seted up at the middle part of dead slot 4, and the inside of connecting hole 5 is rotated through the gear interlock and is connected with fixing bolt 7, and the outside of fixing bolt 7 is placed in mounting hole 6.

Specifically, the elastic sheet 2 is provided with six elastic sheets, and the elastic sheets are symmetrically distributed on the upper end face of the main body 1.

In this embodiment: when main part 1 and bolt fastening, shell fragment 2 will be in the same place with the solid fixed body coupling, then can cause certain extrusion to shell fragment 2, and then can give 1 thrust to the outside of main part to can prevent that it is not hard up.

Specifically, the thread pitch of the upper end and the lower end of the threaded hole 3 is equal.

In this embodiment: the installation of the bolt is convenient.

Specifically, two connection holes 5 are provided, and are opened in the inside of the main body 1.

In this embodiment: the inner part is used and placed with a fixing bolt 7, which in turn fixes the bolt of subject 1 inside its threaded hole 3.

Specifically, the mounting holes 6 are formed in the inner walls of the middle portions of the two sides of the main body 1.

In this embodiment: the outer end of the fixing bolt 7 can be placed.

During the use, it is relative with the object that will fix with the up end of main part 1, then screw hole 3 is twisted on the bolt, when shell fragment 2 links together with the fixed body, the object that is fixed will lead to the fact certain pressure to shell fragment 2, and then can give 1 thrust to the outside of main part, thereby can prevent that main part 1 is not hard up, after main part 1 has been installed, unscrew fixing bolt 7 on right side, then add the curing agent from connecting hole 5 to dead slot 4, and then with the bolt fastening in main part 1's inside, and can extrude to the inboard of screw hole 3 simultaneously through fixing bolt 7, and then can be with the bolt fastening, the device has adopted threefold fixed, can prevent effectively that the nut from becoming flexible.
