AI Technical Summary
When rotating the bolt, the existing riveted nuts are difficult to fix because there are few exposed parts on the outside, which causes the bolt to drive the nut to rotate and cannot be fixed internally.
A rivet nut for sheet metal parts is designed. By setting multiple sets of bumps on the side wall of the press-up nut and setting corresponding grooves on the sheet metal part plate, the bumps are stuck in the grooves to limit the rotation of the nut and avoid following rotation.
It effectively avoids the nut being driven to rotate when the bolt is rotated, ensuring that the bolt can be fixed internally, and improving the fixing stability of the nut.

Description
Technical Field
[0001] The utility model relates to the technical field of nuts, in particular to a riveted nut for sheet metal parts which can prevent rotation. Background Art
[0002] Riveted nuts, also known as pull rivet nuts, are mainly used in the fastening of various metal plates, pipes and other manufacturing industries. They are widely used in the assembly of electromechanical and light industrial products such as automobiles, railways, refrigeration, and elevators. They are mainly used to solve the shortcomings of easy melting of welding nuts on metal sheets and thin tubes, easy welding deformation of base materials, and easy slipping of internal threads. They have the advantages of strong riveting, high efficiency and easy use.
[0003] At present, when the bolt is rotated in the riveted nut, it is not easy to fix the riveted nut because the riveted nut has a small exposed part outside. The rotating bolt may drive the riveted nut to rotate, resulting in the problem that the bolt cannot be screwed into the riveted nut for fixing;
[0004] The reason for this problem is that, currently, the rivet nut is first inserted into the mounting hole on the sheet metal, and then the thread is locked by rotating the bolt. Since the bolt and the rivet nut are threadedly connected, and after the rivet nut is inserted into the sheet metal, there is less exposed part outside. When the bolt is rotated, it is not easy to manually fix the rivet nut, and the rotating bolt can easily drive the rivet nut to rotate, resulting in the bolt being unable to be screwed into the rivet nut for fixing. In view of the shortcomings of the existing technology, we propose a rivet nut with anti-rotation for sheet metal to solve the above problems. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a riveted nut with an anti-rotation function for sheet metal parts, which solves the problem that when the bolt is rotated in the riveted nut, the riveted nut is not easy to be fixed due to the small part of the riveted nut exposed to the outside, which easily causes the rotating bolt to drive the riveted nut to rotate along, resulting in the bolt being unable to be screwed into the riveted nut and fixed.
[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a rivet nut for sheet metal parts with anti-rotation, including a rivet assembly, wherein the rivet assembly includes a pressure rivet nut and a pull rivet stud;
[0007] The rivet nut and the rivet stud are threadedly connected, the end of the rivet nut passes through a sheet metal plate, and a plurality of groups of protrusions are fixedly connected to the end of the rivet nut. A plurality of groups of grooves are provided on the top of the sheet metal plate, and the grooves correspond to the positions of the protrusions, and the protrusions are clamped inside the grooves.
[0008] Preferably, the end of the rivet nut is fixedly connected to a first limiting plate, and the protrusion is fixedly connected to the top of the first limiting plate.
[0009] Preferably, the outer diameter of the pull rivet stud is the same as the inner diameter of the self-clinching nut, and the pull rivet stud is threadedly connected to the inside of the self-clinching nut.
[0010] Preferably, a handle is fixedly connected to the end of the rivet stud, and the end of the handle is rounded.
[0011] Preferably, a plurality of groups of drawing grooves are fixedly connected to the outer peripheral wall of the handle.
[0012] Preferably, a second limiting plate is fixedly connected between the handle and the rivet stud, and the position of the second limiting plate corresponds to that of the first limiting plate.
[0013] Preferably, the outer peripheral wall of the rivet nut is fixedly connected with a plurality of groups of vertical lines.
[0014] The utility model discloses a rivet nut with an anti-rotation function for sheet metal parts, which has the following beneficial effects: the rivet nut with an anti-rotation function for sheet metal parts is provided with multiple groups of protrusions on the side wall of the rivet nut, and multiple groups of grooves are opened on the sheet metal plate. The rivet nut can be clamped and limited by clamping the protrusions in the grooves, which is convenient for assembling and fixing the rivet nut and the rivet stud, and avoids the situation that the rivet nut is easily driven to rotate synchronously when the rivet stud is rotated, resulting in failure of thread locking between the rivet stud and the rivet nut.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The embodiment of the present application provides a rivet nut with an anti-rotation function for sheet metal parts, thereby solving the problem that when the bolt is currently rotated in the rivet nut, the rivet nut is not easy to fix due to the small part of the rivet nut exposed to the outside, which easily causes the rotating bolt to drive the rivet nut to rotate along with it, resulting in the bolt being unable to be screwed into the rivet nut and fixed.
[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] The utility model embodiment discloses a riveted nut for sheet metal parts which can prevent heel rotation.
[0025] According to the attached Figure 1-4 As shown, a rivet nut for sheet metal parts with anti-rotation, including a rivet assembly 2, the rivet assembly 2 includes a pressure rivet nut 201 and a pull rivet stud 202;
[0026] The rivet nut 201 and the rivet stud 202 are threadedly connected, and the end of the rivet nut 201 passes through the sheet metal plate 1. The end of the rivet nut 201 is fixedly connected with multiple groups of protrusions 2011. The top of the sheet metal plate 1 is provided with multiple groups of grooves 101. The positions of the grooves 101 and the protrusions 2011 correspond to each other. The protrusions 2011 are clamped in the inside of the grooves 101. When the rivet nut 201 is inserted into the mounting hole on the sheet metal plate 1, the protrusions 2011 on the side walls of the rivet nut 201 will be inserted into the grooves 101 on the sheet metal plate 1 for clamping and limiting, thereby avoiding the rivet nut 201 from being driven to rotate synchronously when the rivet stud 202 is rotated, resulting in failure of thread locking between the rivet stud 202 and the rivet nut 201.
[0027] The end of the rivet nut 201 is fixedly connected to a first limiting plate 2013, and the protrusion 2011 is fixedly connected to the top of the first limiting plate 2013. The rivet nut 201 can be limited by the first limiting plate 2013 to avoid slipping off the sheet metal plate 1.
[0028] The outer diameter of the pull rivet stud 202 is the same as the inner diameter of the rivet nut 201. The pull rivet stud 202 is threadedly connected to the inside of the rivet nut 201. By rotating the pull rivet stud 202 into the inside of the rivet nut 201, the sheet metal plate 1 can be fixed at the installation position.
[0029] The end of the rivet stud 202 is fixedly connected to a handle 2022 , and the end of the handle 2022 is rounded.
[0030] The outer peripheral wall of the handle 2022 is fixedly connected with a plurality of groups of drawing grooves 2023, and the drawing grooves 2023 facilitate hand-held rotation of the handle 2022.
[0031] A second limiting plate 2021 is fixedly connected between the handle 2022 and the rivet stud 202. The positions of the second limiting plate 2021 and the first limiting plate 2013 correspond to each other. The rivet stud 202 can be limited by the second limiting plate 2021, thereby preventing the rivet stud 202 from abutting against the plate when screwing in, which may cause indentations on the plate.
[0032] The outer peripheral wall of the rivet nut 201 is fixedly connected with multiple groups of vertical grooves 2012, and the vertical grooves 2012 can further increase the friction with the sheet metal plate 1 and perform further limitation.
[0033] When the utility model is in use, the rivet nut 201 is first inserted into the mounting hole on the sheet metal plate 1. At this time, the protrusion 2011 on the side wall of the rivet nut 201 will be inserted into the groove 101 on the sheet metal plate 1 for clamping and restriction. Then, the rivet stud 202 is rotated to pass its thread through the interior of the rivet nut 201 and inserted into the wall or other installation location to fix the sheet metal plate 1.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
