Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a novel supporting rivet structure. Background Art

[0002] Rivets are mechanical fasteners commonly used to connect two or more components. Typically made of metal, they offer high strength and durability. Support rivet structures utilize rivets as supporting elements, positioned appropriately to enhance the stability and load-bearing capacity of the structure.

[0003] After searching, a Chinese patent discloses a blind rivet (publication number CN217519029U), which includes a rivet sleeve and a core assembly; an end cap is provided at one end of the rivet sleeve, and the rivet sleeve is provided with a mounting hole that matches the core assembly, and the core assembly is arranged in the rivet sleeve through the mounting hole; the core assembly includes a detachably connected clamping rod and a riveting rod, the clamping rod is located at the end of the rivet sleeve close to the end cap, and the clamping rod is provided with an external thread at the end away from the riveting rod.

[0004] This patented technology enables the clamping rod to be used multiple times, improves the utilization rate of the clamping rod, and reduces production costs and usage costs. However, the patented technology only uses the clamping rod to pull the rivet rod to deformation, and uses the deformed rivet rod to fix and rivet two objects. However, this riveting is completed by the deformed rivet rod. If the hole is too large, or the hole continues to wear and become larger in subsequent use, simply using the deformed rivet rod as a supporting structure becomes insufficient and may even cause the rivet to fall off, resulting in an accident. Therefore, those skilled in the art provide a new supporting rivet structure to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to make up for the above shortcomings, the present invention provides a new supporting rivet structure, which aims to improve the existing technology of using riveting rods as supporting structures. When the holes for installing rivets are too large or the holes are worn and enlarged after long-term use, the rivets may fall off, causing unexpected problems.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A novel support rivet structure includes a hexagonal nail cap and a pull head. The bottom of the hexagonal nail cap is fixedly connected to a disassembly structure. The bottom of the disassembly structure is fixedly connected to a plurality of support bars. The bottoms of the plurality of support bars are fixedly connected to the top of the pull head. A blocking column is fixedly connected to the middle of the top of the pull head. The top of the blocking column is fixedly connected to a pull rod. A pre-bent groove is provided on the side of the support bar close to the pull rod.

[0008] Through the above technical solution, it is achieved that the pull head can be driven to move upward under the action of the rivet gun, and then the support bar is squeezed to deform the support bar. Moreover, since a pre-bent groove is opened on the back side of the outward inclined part of the pre-bent groove, the support bar is relatively weak at the opening of the pre-bent groove, so it will bend at the pre-bent groove and unfold into a regular unfolding shape, and can unfold to the maximum area, thereby expanding the support area and making the rivet less likely to fall off.

[0009] Furthermore, the easily disassembled structure includes a connecting inner rod, the top of the connecting inner rod is fixedly connected to the middle of the bottom end of the hexagonal nail cap, the external thread of the connecting inner rod is connected to the connecting outer ring, and the tops of the plurality of support bars are fixedly connected to the bottom of the connecting outer ring;

[0010] Through the above technical solution, the connecting outer ring can be screwed onto the outside of the connecting inner rod, so the support bar can be installed on the connecting inner rod. Similarly, the connecting outer ring can be quickly removed from the connecting inner rod, and then the support bar can be quickly removed from the connecting outer ring.

[0011] Furthermore, a plurality of anti-stripping marks are provided on the outside of the pull rod, and a sealing sleeve is provided on the outside of the blocking column;

[0012] Through the above technical solution, the function of the sealing sleeve is to increase the sealing performance, thereby preventing liquid from entering through the middle hole of the rivet, thereby preventing the rivet from rusting.

[0013] Furthermore, the shape of the pre-bent groove is a triangle;

[0014] Through the above technical solution, the pre-bent groove becomes larger from the inside to the outside, so it is more convenient to bend outward.

[0015] Furthermore, the interior of the hexagonal nail cap is provided with an inner hexagonal groove, and the interior of the hexagonal nail cap is provided with a transverse groove;

[0016] Through the above technical solution, the design of the hexagonal slot enables the hexagonal nail cap to be removed with an Allen wrench, and the design of the horizontal slot enables the hexagonal nail cap to be removed with a flat-blade screwdriver or a relatively hard iron sheet.

[0017] Furthermore, the tops of the plurality of support bars are evenly distributed on the bottoms of the plurality of connecting outer rings;

[0018] Through the above technical solution, the uniform distribution can enable the support bars to unfold regularly when bending, thereby making the object more firmly riveted.

[0019] Furthermore, the pull rod passes through the connecting inner rod and the top of the hexagonal nail cap;

[0020] Through the above technical solution, the pull rod can be conveniently pulled using a rivet gun only after it passes through the inner rod and the hexagonal nail cap.

[0021] Furthermore, the support bar is inclined toward a side away from the pull rod;

[0022] Through the above technical solution, the side of the support bar away from the pull rod is tilted outward, which makes it easier for the support bar to bend outward.

[0023] The utility model has the following beneficial effects:

[0024] 1. In the utility model, through the composition of the hexagonal nail cap, support bar, blocking column, pull head, pre-bent groove and pull rod, it is achieved that when the pull rod is pulled, due to the outward inclination of the support bar and the setting of the pre-bent groove, the support bar can be expanded outward and deformed regularly, thereby making the support area larger and the support more stable, thereby avoiding the rivet falling off due to the hole being too large or long-term wear causing the hole to become larger, increasing the stability during riveting, and avoiding accidents.

[0025] 2. In the utility model, by connecting the inner rod, connecting the outer ring, the hexagonal nail cap and the inner hexagonal slot, the hexagonal nail cap can be easily removed after the rivet is riveted, and then the riveted objects can be easily separated, so that after the riveting is wrong, it can be quickly disassembled, saving time and labor and improving practicality.

The top of the blocking column 4 is fixedly connected to a pull rod 7, and the pull rod 7 can drive the pull head 5 to move upward, thereby driving the support bar 3 to deform, and then can It can be supported between two objects, so as to provide stable support and complete riveting. A pre-bent groove 6 is provided on the side of the support bar 3 close to the pull rod 7. During the deformation of the support bar 3, the pre-bent groove 6 causes the area with the pre-bent groove 6 to be relatively weak, so it can be deformed, and cooperate with the hexagonal nail cap 1 to complete the riveting fixation between the two objects. A plurality of anti-slip marks 8 are provided on the outside of the pull rod 7. The anti-slip marks 8 can increase the friction force, thereby preventing the pull rod 7 from slipping. A sealing sleeve is provided on the outside of the blocking column 4, which can improve the sealing performance. The pre-bent groove 6 is in the shape of a triangle. The pre-bent groove 6 is triangular, which makes the support bar 3 bend more regularly. The support bar 3 tilts toward the side away from the pull rod 7. The tilt of the support bar 3 can make the support bar 3 deform outward when deformed.

[0034] Reference Attachment Figure 1-Figure 3The disassembly structure 2 includes a connecting inner rod 201, which can provide conditions for installation and disassembly.
