Description

Technical Field

[0001] The utility model belongs to the technical field of rivets, and more specifically relates to a rivet assembly. Background Art

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with a through hole and a cap at one end. In riveting, the parts are connected by deformation or interference fit. Rivets come in many different types and styles.

[0003] For example, our patent publication number CN116172382A discloses a hook, which discloses a rivet having a rivet cap and a rivet column. The rivet column is fixedly mounted on the upper end of the rivet cap, with a first step formed between the rivet column and the rivet cap. The rivet column includes a rivet rod and a rivet seat. The rivet rod and the rivet seat are cylindrical, with the cylindrical diameter of the rivet seat being larger than the cylindrical diameter of the rivet rod. A second step is formed between the rivet rod and the rivet seat. As shown in the figure, the left and right sides of the rivet rod are respectively provided with a first section and a second section. With this arrangement, the first and second sections increase the area of ​​the second step. A rivet hole is provided through the cylindrical portion of the rivet rod, and the rivet hole is provided with a thread. The rivet column of the rivet is set through the positioning hole; the diameter of the rivet column is greater than the distance from the first section to the second section, and the first section and the second section of the rivet are in contact with the inner wall of the positioning hole. With this arrangement, the rivet column will not rotate in the positioning hole; when the fixing bolt is fixed to the rivet, it directly operates on the fixing bolt, and there is no need to perform additional actions to fix the rivet, making the fixation of the hook more convenient.

[0004] However, this rivet has some drawbacks. The contact area around the first step of the rivet is uniform across all sides. This arrangement allows the rivet to be stuck in the positioning hole. However, the upper end of the first step's contact surface abuts the steel plate's abutment surface, but the upper end is idle and has no practical use. Furthermore, the contact area of ​​the lower end surface is insufficient, potentially leading to instability when abutting against the fixed plate. Finally, the distance from the edge of the original rivet's second step surface to the outermost edge of the rivet is equal. Applying excessive force when removing the rivet outward can cause the protruding surface of the rivet to become stuck on the upper side of the steel plate, preventing quick removal and slowing down the removal process. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a rivet assembly, which can realize eccentric setting, increase the contact area of ​​abutment, and is suitable for installation of steel plates with different thicknesses.

[0006] The utility model provides a rivet assembly, comprising a first column, a second column and a third column arranged axially in sequence; the second column is eccentrically arranged with the first column, and the end face of the second column on the far side of the first column is a load-bearing part; at least one limiting cutting edge is provided on the side of the third column; the end face of the second column and the third column form a limiting step at least where the limiting cutting edge is located; a mounting plate is provided outside the third column, and a stop hole matching the contour of the third column is provided on the surface of the mounting plate; the stop hole has a stop edge matching the limiting cutting edge; the mounting plate is nested in the outer periphery of the third column and abuts against the limiting step; a threaded through hole is provided in the center of the third column to be connected with a screw of an external device; the end face of the screw abuts against the surface of the mounting plate; a plug-in cavity is formed between the mounting plate and the first column; the plug-in cavity is nested outside the fixing plate of the external device, and the end face of the fixing plate abuts against the load-bearing part.

[0007] As a further improvement of the present invention, a hook is provided on the surface of the mounting plate, and the hook is fixedly connected to the mounting plate.

[0008] As a further improvement of the present invention, the end surface of the load-bearing part is arranged inclined.

[0009] As a further improvement of the present invention, the edge of one end of the second pillar is flush with the edge of one end of the first pillar.

[0010] As a further improvement of the present invention, a plurality of fixing points are provided on the front side of the mounting plate, and the fixing points are dome-shaped and arranged in an arc shape on the front side of the mounting plate.

[0011] As a further improvement of the present invention, the hook is further provided with a double hook; the double hook is in a curved hook shape, and the curved hook portion of the double hook is further provided with a protective cover, and the protective cover is made of elastic material.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Compared to existing technologies, the eccentric arrangement of the second column in this embodiment effectively increases the contact surface of the force-applying portion, ensuring more uniform force applied to the rivet. Furthermore, the varying thicknesses of the force-applying portion of the first column effectively increase the versatility of contact with steel plates of varying thicknesses. Finally, the eccentric arrangement of the second column also effectively improves subsequent disassembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The first column 1 , the load-bearing part 11 , the second column 2 , the limiting step 21 , the third column 3 , the limiting cutting edge 31 , the thread 4 , the mounting plate 5 , the anti-rotation hole 51 , the hook 52 , and the screw 6 . DETAILED DESCRIPTION

[0027] Specific embodiment 1: Please refer to Figure 1-9 A rivet assembly includes a first column 1, a second column 2 and a third column 3. The first column 1, the second column 2 and the third column 3 are arranged in sequence in a vertical direction and are fixedly connected to each other and are made into one piece.

[0028] The first column 1 is the bottom layer of rivets and is cylindrical in shape. The thickness of the first column 1 increases from one side to the other to form an inclined surface. A load-bearing portion 11 is formed from the edge of the smallest end of the first column 1 to the edge of the second column 2.

[0029] The second column 2 is eccentrically positioned at the thickest end of the first column 1. The connection surface between the second column 2 and the first column 1 increases in size from the end away from the load-bearing portion 11 to the other end, so that the second column 2 is fixedly connected to the increasing surface of the first column 1 and the upper surface of the second column 2 is horizontal. The diameter of the second column 2 is smaller than that of the first column 1, forming a protruding stop step 21.

[0030] The third pillar 3 is located in the middle of the second pillar 2 and is fixedly connected to the second pillar 2. The diameter of the third pillar 3 is smaller than that of the second pillar 2. The third pillar 3 has symmetrical limiting edges 31 along the center line of the rivet, and the limiting edges 31 on both sides are cross-sectional views.

[0031] A thread 4 is provided along the middle of the third column 3 and passes through the entire rivet to connect with a screw 6 of an external device.

[0032] A mounting plate 5 is provided on the outer side of the third pillar 3, and a stop hole 51 matching the contour of the third pillar 3 is provided on the surface of the mounting plate 5. The stop hole 51 has a stop edge matching the limiting edge 31. The mounting plate 5 is nested in the outer periphery of the third pillar 3 and abuts against the limiting step 21. The abutting end face of the screw 6 presses against the surface of the mounting plate 5. A hook 52 is also provided on the lower end surface of the mounting plate 5, and the hook 52 is fixedly connected to the mounting plate 5. The hook 52 is also provided with a double hook, and the double hook is in a curved hook shape. The curved hook part of the double hook is also provided with a protective cover, and the protective cover is made of elastic material. A plurality of fixing points are provided on the front side of the mounting plate 5, and the fixing points are dome-shaped and arranged in a circular arc shape on the front side of the mounting plate 5.

[0033] A plug-in cavity is formed between the mounting plate 5 and the first column 1, and the plug-in cavity is nested outside the peripheral fixing plate, and the end surface of the fixing plate abuts against the load-bearing part 11. The fixing plate is an L-shaped plate so that the fixing plate can be embedded in the plug-in cavity.

[0034] Working principle:

[0035] During use, the third post is embedded in the surface of the fixed plate. Simultaneously, the additional abutment portion of the second post abuts against the edge of the fixed plate. The eccentric arrangement of the second post effectively increases the contact surface of the force-applying portion, ensuring a more uniform force distribution on the rivet. Furthermore, the varying thickness of the force-applying portion of the first post effectively increases the versatility of abutment with fixed plates of varying thicknesses. Finally, the eccentric arrangement of the second post also effectively improves subsequent disassembly efficiency.

[0036] Specific embodiment 2: Please refer to Figure 10A rivet assembly is provided, differing from the first embodiment in that the fixing plate is a plate with a gourd-shaped through hole. The fixing plate includes a plurality of evenly spaced fixing holes on its surface. The fixing holes are gourd-shaped, and the largest hole diameter of the fixing hole matches the diameter of the first column 1, so that the first column 1 can pass through the fixing hole. The smallest hole diameter of the fixing hole matches the diameter of the second column 2, so that the second column 2 can slide up and down along the fixing hole.

[0037] Working principle:

[0038] When the present invention is in use, the third column is embedded in the fixing hole of the fixing plate, and the clamping portions on both sides are used to abut and slide against the inner wall of the fixing hole of the fixing plate. When the third column slides to the lower end or the abutting end of the fixing hole of the fixing plate, the extra force-applying portion abuts against the rear side wall of the fixing hole of the fixing plate. Simultaneously, the extra abutting portion of the second column abuts against the edge side wall of the fixing hole of the fixing plate.
