These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items.

[0036] Please refer to Figures 1-2 , the assembly of the present embodiment, wherein the fastener 1 has a first end and a second end arranged opposite along the axial direction, the first end of the fastener 1 is provided with a flange portion 11, and the second end of the fastener 1 is provided with a rivet portion 12;

[0037] The base plate 3 is used for riveting with the rivet portion 12 of the fastener 1;

[0038] The mounting assembly 4 is used to be clamped between the first end and the second end of the fastener 1;

[0039] The combination further comprises a fastener gap compensation device 2, which is used to be clamped between the first end and the second end of the fastener 1, so that the gap between the first end and the second end of the fastener 1 in the axial direction is filled, and the fastener gap compensation device 2 is made of elastic material.

[0040] Specifically, in the fastener gap compensation device 2 of the embodiment, the fastener gap compensation device 2 has an internally hollow mounting groove 21 connected with an open opening 22, the diameter of the mounting groove 21 matches the diameter of the fastener 1, and the mounting groove 21 is used to be sleeved and surrounded between the first end and the second end of the fastener 1, and the fastener gap compensation device 2 is made of elastic material.

[0041] Through the above structure, in use, the operator only needs to sleeve the fastener gap compensation device 2 between the first end and the second end of the fastener 1 during installation, specifically, the opening 22 of the fastener gap compensation device 2 is sleeved towards the column direction of the middle part of the fastener 1, which can be sleeved near the flange part 11 side of the fastener 1, that is, in use, the flange part 11 and the mounting assembly 4 which should originally contact the flange part are separated by the fastener gap compensation device 2 in the utility model, the upper side of the fastener gap compensation device 2 abuts against the bottom surface of the flange part 11, and the lower side of the fastener gap compensation device 2 abuts against the top surface of the mounting assembly 4, and then the whole structure is placed on the bottom plate 3 to be riveted, and the riveting mechanism is used to rivet the fastener 1. Specifically, in the riveting process, the fastener gap compensation device 2 may be extruded in the axial direction and elastically deformed under the joint extrusion of the bottom surface of the flange part 11 and the top surface of the mounting assembly 4.

[0042] In the above use process, due to the existence of the fastener gap compensation device 2 between the bottom surface of the flange part 11 and the top surface of the mounting assembly 4, the problem of the gap between the fastener 1 and the top surface of the mounting assembly 4 caused by the deviation of the welding size of the fastener 1 is compensated, the fastener gap compensation device 2 itself is equivalent to a kind of elastic filler, the stress between the fastener 1 and the mounting assembly 4 is relieved by the elasticity of the fastener gap compensation device 2, and the stability between the fastener 1 and the mounting assembly 4 after riveting and installation is further enhanced due to the fact that the elastic fastener gap compensation device 2 can completely fill the original gap after deformation.

[0043] It is worth noting that, on the basis of the structure of the utility model, the axial thickness size of the fastener gap compensation device 2 meets the condition that it can still be padded between the flange part 11 of the fastener 1 and the top surface of the mounting assembly 4 when it completes the maximum deformation. That is to say, there is necessarily a certain gap in the axial direction between the flange part 11 of the original fastener 1 and the top surface of the mounting assembly 4 for placing the fastener gap compensation device 2.

[0044] The following are several embodiments provided by the utility model, and the purpose is to realize better or more functional fastener 1 installation effect:

[0045] Embodiment 1

[0046] Please refer to Figure 6 , the size of the opening 22 gradually expands from the position of the mounting groove 21. The size of the opening 22 is at least larger than the diameter of the fastener 1 in this embodiment, and the opening 22 is sleeved to the position of the fastener 1 during installation. The gradually open opening 22 actually plays a certain installation guiding role, which promotes the fastener gap compensation device 2 to slide in the direction of the mounting groove 21.

[0047] Embodiment 2

[0048] Please refer to Figure 6 , the size of the smallest opening 22 is smaller than the diameter of the fastener 1 and the diameter of the mounting groove 21. That is to say, in this embodiment, the elastic material properties of the fastener gap compensation device 2 itself are actually used to make the installation of the fastener gap compensation device 2 itself in the form of snap installation. During the complete sleeving of the fastener gap compensation device 2 on the fastener 1, the fastener gap compensation device 2 with the smallest opening 2 size position will rub with the outer wall of the fastener 1, and on the basis of a certain elastic deformation of the fastener gap compensation device 2, the fastener gap compensation device 2 slides into and clamps, and finally the fastener 1 is sleeved with the fastener gap compensation device 2. On the basis of this embodiment, the sleeving of the fastener gap compensation device 2 can be more stable.

[0049] Embodiment 3

[0050] Please refer to Figure 1 , Figure 6, the fastener gap compensation device 2 is provided with a groove 23 bent in the axial direction, and the groove 23 is arranged in the circumferential direction around the fastener gap compensation device 2. Specifically, through the arrangement of the groove 23, in the process of riveting and other cooperation of the fastener 1 with the mounting assembly 4, the groove 23 and the connection position of the fastener gap compensation device 2 are elastically deformed by bending, so that the fastener gap compensation device 2 itself is more easily bent, the resistance of elastic deformation is smaller, and from the material point of view, the fastener gap compensation device 2 itself has lower material cost. Specifically, the bottom surface of the groove 23 faces the top surface of the mounting assembly 4, and in fact, the recessed space at the top of the groove 23 is used to form a space for the flange part 11 of the fastener 1, that is, the actual radial size of the fastener gap compensation device 2 in the embodiment is slightly larger than the radial size of the flange part 11.

[0051] Embodiment 4

[0052] Please refer to Figure 3 In the embodiment, the fastener gap compensation device 2 is arranged in a C shape, and the radial edge of the fastener gap compensation device 2 is provided with a positioning part 24 which is truncated in a direction perpendicular to the radial direction, and the number of the positioning part 24 is multiple. Specifically, the number of the positioning part 24 can be arranged as two on both sides of the opening 22, and when the horizontal pushing force of the fastener gap compensation device 2 is very large, the positioning part 24 can play a role of angle positioning to avoid the deviation of the fastener gap compensation device 2.

[0053] Embodiment 5

[0054] Please refer to Figure 1 and Figure 3 The position of the fastener 1 near the flange part 11 is provided with a mounting section 13 which is reduced in diameter in the radial direction, and the mounting section 13 is used to set the fastener gap compensation device 2, and the diameter size of the mounting section 13 matches the diameter size of the mounting groove 21. Through the arrangement of the mounting section 13, the axial limiting function of the fastener gap compensation device 2 itself can be played after the fastener gap compensation device 2 is set, that is, the mounting section 13 itself is actually the accommodation space of the fastener gap compensation device 2, and the existence of the mounting section 13 also indirectly increases the size of the fastener gap compensation device 2, so that the fastener gap compensation device 2 has more possibilities in terms of elastic performance.

[0055] Embodiment 6

[0056] Please refer to Figure 1 The riveting part 12 of the fastener 1 can be arranged as a positive direction riveting structure, which is used to be riveted with the bottom plate 3 in the first direction. In the installation process of the embodiment, the riveting part 12 of the fastener 1 is riveted and installed on the bottom plate 3 in the first direction from top to bottom.

[0057] Embodiment 7

[0058] Referring to Figure 4 The riveting portion 12 of the fastener 1 can be provided as a reverse direction riveting structure for riveting with the base plate 3 in a direction opposite to the first direction. In this embodiment, the riveting portion 12 of the fastener 1 is installed on the base plate 3 in a reverse direction from the bottom to the top in the first direction. The reverse direction riveting of the fastener 1 from the back can improve the tensile and lateral thrust resistance of the fastener 1.

[0059] Embodiment 8

[0060] Referring to Figure 5 The side of the riveting portion 12 of the fastener 1 opposite to the riveting direction has a flower tooth 14. The flower tooth 14 is used to assist the riveting of the fastener 1, in which part of the metal material in the base plate 3 is clamped into the flower tooth 14 of the fastener 1, and the flower tooth 14 is used as a substitute for the original material containing portion to achieve greater torsional resistance.

[0061] Specifically, in the above embodiments, the position between the flange portion 11 and the riveting portion 12 of the fastener 1 is used for being provided in the installation assembly 4, and the axial size between the flange portion 11 and the riveting portion 12 of the fastener is greater than the axial size of the installation assembly 4, so that the placement of the fastener gap compensation device 2 itself can be accommodated.

[0062] Further, the radial size of the fastener gap compensation device 2 is greater than the radial size of the flange portion 11 of the fastener 1, so that the groove 23 of the fastener gap compensation device 2 can actually have sufficient space for accommodating the edge position of the flange portion 11 after deformation, avoiding mutual extrusion, causing additional wear or stress.

[0063] The above disclosure is only a preferred and feasible embodiment of the utility model, and does not limit the patent application range of the utility model, so that any equivalent technical changes made by referring to the contents of the utility model specification and drawings are included in the patent application range of the utility model.

[0064] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0065] Although the present application is described by embodiments, those skilled in the art know that there are many modifications and changes of the present application without departing from the spirit of the present application, and it is hoped that the attached embodiments include these modifications and changes without departing from the present application.
