TECHNICAL FIELD

[0001] The present application relates to the field of parts, in particular to a ring groove rivet assembly with combined structure. BACKGROUND

[0002] The ring groove rivet assembly is composed of a ring groove rivet and a sleeve, and is installed by passing the ring groove rivet through the through hole of the part to be fixed, then installing the sleeve on the other side, and then locking by a rivet gun.

[0003] The ring groove rivet refers to a special rivet made of high-quality carbon steel, which has high riveting strength and is firm and reliable. Its biggest feature is good vibration resistance, wide application and convenient construction.

[0004] The existing ring groove rivet is broken when the clamping section is pulled backward by the rivet gun during installation, and the sleeve is deformed by the rivet gun, tightly wrapping the riveting section, and the partially deformed sleeve is stuck in the ring groove on the locking section of the riveting section. The ring groove rivet and the sleeve are used only once in the whole process, which makes the utilization rate of the material not high. SUMMARY

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present application are described in detail below with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the protection scope of the present application can be more clearly and definitely defined.

[0019] Please refer to Figs. 1 to 3 , the embodiments of the present application include:

[0020] The annular groove rivet assembly with the combined structure includes a rivet 1 and a rivet sleeve 2, the rivet sleeve 2 is matched with the rivet 1, the rivet 1 includes a rivet cap 3, a riveting section 4 and a clamping section 5, and a combined structure is arranged between the riveting section 4 and the clamping section 5, so that the riveting section 4 and the clamping section 5 can be recycled, thereby increasing the utilization rate of the annular groove rivet 1.

[0021] The combined structure is threadedly connected between two round holes on the riveting section 4 and the clamping section 5 through the connecting shafts 10 arranged at both ends, and the connecting shafts 10 are preliminarily connected with the round holes, and the threaded connection can make the connection between the riveting section 4, the combined structure and the clamping section 5 firm.

[0022] The combination structure includes riveting extension section 6 and clamping extension section 7, which are connected with riveting section 4 and clamping section 5 respectively, and the riveting extension section 6 and the clamping extension section 7 play a transition role, avoiding the riveting section 4 and the clamping section 5 being directly connected with the neck breaking groove 8, thereby affecting the stress when being pulled off.

[0023] The riveting extension section 6 and the clamping extension section 7 are provided with a neck breaking groove 8, which is circular arc-shaped, and the neck breaking groove 8 is used for installing the pull-off of the clamping section 5, thereby separating the riveting extension section 6 and the clamping extension section 7.

[0024] The circular arc-shaped middle is provided with an auxiliary groove 9, which is triangular, used for auxiliary pull-off, because the riveting section 4 and the clamping section 5 are connected by the combination structure, the firmness is lower than that of the integral structure, so the pull force of the rivet gun needs to be relatively reduced, thereby avoiding the connection shaft 10 from being separated from the round hole, so the auxiliary groove 9 can facilitate the rivet gun to pull off the clamping section 5.

[0025] The connection between the riveting extension section 6 and the riveting section 4 and the connection between the clamping extension section 7 and the clamping section 5 are provided with a connecting ring 11, and the two connecting rings 11 are respectively provided with a locking nut 12, and the two connecting rings 11 are provided with a ring of locking threads, which are matched with the internal threads of the locking nut 12, and the connecting ring 11 is used for connecting with the locking nut 12, thereby connecting the riveting section 4 and the combination structure and the combination structure and the clamping section 5 more firmly, avoiding the riveting section 4 and the combination structure or the combination structure and the clamping section 5 from being separated due to the excessive pull force of the rivet gun.

[0026] In use, the riveting section 4, the combination structure and the clamping section 5 are connected in sequence, at this time the rivet 1 is passed through the object to be connected and the nail sleeve 2 is sleeved, and the rivet gun is used for installation, first the rivet gun clamps the clamping section 5 through the ring groove on the clamping section 5 and pulls to the right, until the neck breaking groove 8 breaks and the clamping section 5 is separated, thereby playing a weight-reducing role, at the same time the nail sleeve 2 is deformed under the extrusion of the rivet gun, thereby tightly wrapping the riveting section 4, and part of the deformed nail sleeve 2 is locked with the ring groove on the locking section 13 of the riveting section 4, and the riveting extension section 6 is unscrewed, thereby completing the installation.

[0027] In the cycle use, the nail sleeve 2 is damaged by tools, the riveting section 4 is removed, and the new combination structure and the clamping structure after the last separation are connected, and the installation operation is repeated.

[0028] Different from the prior art, the annular groove rivet assembly with the combined structure can increase the utilization rate of the annular groove rivet.

[0029] In the description of the present application, it should be noted that the components are all general standard components or components known to those skilled in the art, the structure and principle of which can be known by the technical personnel through the technical manual or obtained through the conventional test method, the terms "up", "down", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
