Preferably, the internal thread is arranged at the end part of the connecting groove, the connecting stud is screwed into the connecting sleeve, the inner wall of the connecting sleeve is damaged, the thread is generated, and the connecting sleeve and the connecting stud are tightly connected together.

Preferably, the center of the fixed disk is provided with a through hole communicated with the connecting groove, the through hole is internally provided with a positioning bolt, the center of the connecting end of the connecting stud is provided with a bolt connecting groove, and the positioning bolt penetrates through the connecting groove of the fixed disk and the bolt connecting groove.

Preferably, one end of the connecting stud, which is opposite to the connecting end, is provided with a sealing washer, and the diameter of the sealing washer is larger than that of an opening at the end part of the connecting groove.

Preferably, the connecting stud is sleeved with a gasket, and the outer wall of the gasket is of an inclined structure.

Preferably, the side wall of the fixed disk is provided with a hexagonal groove.

The invention has the advantages that: the connecting groove has been seted up inside the adapter sleeve, the connecting groove is slope round platform shape structure, and only set up the internal thread at the tip of connecting groove, the screw thread is not seted up at other positions, make connecting stud when closing soon and being connected to the adapter sleeve inside, destroy the adapter sleeve inner wall, produce the screw thread at the screw in-process, can make the adapter sleeve inseparabler with being connected between the connecting stud, the screw thread can not produce the damage phenomenon, fixed effect to the hinge is better, the tip that connects the groove sets up the internal thread, can be to connecting stud at screw in adapter sleeve in-process, play the guide effect, thereby make things convenient for the screw in, the result of use is better.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-4, this embodiment the hinge fastening bolt that antiskid falls, its characterized in that: including connecting stud 10 and adapter sleeve 20, be equipped with external screw thread 11 on connecting stud 10's the outer wall, connecting groove 22 of depositing connecting stud 10 is seted up to the inside center department of adapter sleeve 20, connecting groove 22 is round platform shape structure, the great opening of connecting groove 22 is located the adapter sleeve 20 tip, the tip opening diameter of connecting groove 22 is greater than connecting stud 10 diameter, be equipped with internal thread 23 in connecting groove 22's the tip inner wall, it is equipped with fixed disk 21 to lie in connecting groove 22 open end opposite side on the adapter sleeve 20, formula structure as an organic whole between fixed disk 21 and the adapter sleeve 20.

At the inside connecting groove 22 of having seted up of adapter sleeve 20, connecting groove is slope round platform shape structure, and only set up the internal thread at the tip of connecting groove 22, the screw thread is not seted up at other positions, make connecting stud 10 close soon be connected to adapter sleeve 20 inside, destroy adapter sleeve 20 inner wall, produce the screw thread at the screw in-process, can make the connection between adapter sleeve 20 and the connecting stud 10 inseparabler, the screw thread can not produce the damage phenomenon, fixed effect to the hinge is better, set up the internal thread at the tip that connects groove 22, can be to connecting stud 10 at screw in-process, play the guide effect, thereby make things convenient for the screw in, the result of use is better.

The center of the fixed disc 21 is provided with a through hole 211 communicated with the connecting groove 22, a positioning bolt 30 is arranged in the through hole 211, the center of the connecting end of the connecting stud 10 is provided with a bolt connecting groove 13, and the positioning bolt 30 penetrates through the fixed disc 21 and the bolt connecting groove 13.

The positioning bolt 30 penetrates through the fixed disc to be connected into the bolt fixing groove 13, so that the position between the connecting sleeve 20 and the connecting screw post 10 can be further limited, the position between the connecting sleeve 20 and the connecting screw post 10 is more stable, and the using effect is better.

The connecting stud 10 is provided with a sealing washer 12 at the end opposite to the connecting end, and the diameter of the sealing washer 12 is larger than that of the opening of the end of the connecting groove 22.

Through the setting of seal ring 12 for the seam crossing of adapter sleeve 20 and connection screw post 10 junction is sealed, avoids steam to enter into the seam between adapter sleeve 20 and the connection screw post 10 and produces the corrosion phenomenon, makes the life increase of adapter sleeve 20 and connection screw post 10.

The connecting stud 10 is sleeved with a washer 40, and the outer wall of the washer 40 is of an inclined structure.

Through the arrangement of the gasket 40, the end position of the connecting groove 22 can be filled more fully, the connection between the connecting sleeve 20 and the connecting screw post 10 is tighter, and the stability of the connecting sleeve is further improved.

The side wall of the fixed disk 21 is provided with a hexagonal groove 212.

Through the arrangement of the hexagonal groove 212, a user can conveniently use the hexagonal screwdriver to screw the fixed disk 21, and the operation is convenient for the user.

In this embodiment, during the use, the connecting sleeve 20 is first inserted into the hinge, and then the connecting stud 10 is screwed into the connecting sleeve 20, and the connecting stud 10 is screwed, so that the external thread 11 on the connecting stud 10 damages the inner wall of the connecting sleeve 20, and the inner wall of the connecting sleeve 20 gradually forms an internal thread and is connected with the external thread 11 on the connecting stud 10, so that the connecting sleeve 20 is connected with the connecting stud 10, and then the positioning bolt 30 passes through the through hole 211 formed on the fixed disk 21 and is connected to the bolt connecting groove 13 formed on the connecting stud 10, so as to further limit the positions of the connecting sleeve 20 and the connecting stud 10.
