[0033] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments.

[0034] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.
[0035] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. 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 depending on the actual situation.
[0036] See also Figure 1-2 , is a combination of the present embodiment, wherein the fastener 1 has a first end and a second end disposed opposite to each other in 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] A bottom plate 3, the bottom plate 3 is used to be riveted to the riveting portion 12 of the fastener 1;
[0038] An installation component 4, the installation component 4 is used to be clamped at a position between the first end and the second end of the fastener 1;
[0039] Among them, the assembly also includes 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 axial gap between the first end and the second end of the fastener 1 is filled, and the fastener gap compensation device 2 is set to an elastic material.
[0040] Specifically, in the fastener gap compensation device 2 of the present embodiment, the fastener gap compensation device 2 has a hollow mounting groove 21, the mounting groove 21 is connected to an open opening 22, the diameter size of the mounting groove 21 matches the diameter size of the fastener 1, the mounting groove 21 is used to be sleeved and surrounded at a position between the first end and the second end of the fastener 1, and the fastener gap compensation device 2 is set to an elastic material.
[0041] Through the above structure, when 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 the installation process. Specifically, the opening 22 of the fastener gap compensation device 2 is sleeved toward the column direction of the middle part of the fastener 1, and can be sleeved near the flange 11 side of the fastener 1. That is to say, during use, the flange 11 and the installation component 4 that should originally be in contact with the flange are separated from each other by the fastener gap compensation device 2 of the present invention, and the upper side of the fastener gap compensation device 2 abuts against the bottom surface of the flange 11, and the lower side of the fastener gap compensation device 2 abuts against the top surface of the installation component 4. Then, after the overall structure is placed on the base plate 3 to be riveted, the fastener 1 is riveted with the help of the riveting mechanism. Specifically, during the riveting process, the fastener gap compensation device 2 may be extruded along the axial dimension, and elastically deformed under the joint abutment and extrusion of the bottom surface of the flange 11 and the top surface of the installation component 4.
[0042] During the above-mentioned use, due to the presence of the fastener gap compensation device 2 between the bottom surface of the flange portion 11 and the top surface of the mounting component 4, the problem of the axial dimension of the fastener 1 being too long and the gap between the top surface of the mounting component 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 the presence of an elastic filling item. With the help of its own elasticity, the stress between the fastener 1 and the mounting component 4 is relieved and eliminated. Since the elastic fastener gap compensation device 2 can completely fill the original gap position after deformation, it can also further enhance the stability between the fastener 1 and the mounting component 4 after riveting installation.
[0043] It is worth noting that, based on the structure of the present invention, the axial thickness dimension of the fastener gap compensation device 2 satisfies that it can still be placed between the flange portion 11 of the fastener 1 and the top surface of the mounting assembly 4 when it completes the maximum deformation. In other words, there must be a certain axial gap between the flange portion 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 present invention, the purpose of which is to achieve a better or more functional fastener 1 installation effect:
[0045] Example 1
[0046] See also Figure 6 The size of the opening 22 gradually increases from the position of the installation groove 21. The size of the opening 22 is at least larger than the diameter of the fastener 1 in this embodiment. During the installation process, the opening 22 is set toward the position of the fastener 1. The gradually opening opening 22 actually plays a certain installation guide role, prompting the fastener gap compensation device 2 to slide toward the installation groove 21.
[0047] Example 2
[0048] See also Figure 6 , the size of the smallest opening 22 is smaller than the diameter of the fastener 1 and the diameter of the installation slot 21. That is to say, in this embodiment, the elastic material properties of the fastener gap compensation device 2 are actually used to make the installation of the fastener gap compensation device 2 itself a snap-on installation. When the fastener gap compensation device 2 is completely sleeved on the fastener 1, the fastener gap compensation device 2 with the smallest opening 2 size position will rub against 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 in and clamps, and the fastener 1 is finally sleeved together with the fastener gap compensation device 2. On the basis of this embodiment, a more stable sleeve of the fastener gap compensation device 2 can be achieved.
[0049] Example 3
[0050] See also Figure 1 , Figure 6The fastener gap compensation device 2 has a groove 23 bent out along the axial direction, and the groove 23 is arranged circumferentially around the fastener gap compensation device 2. Specifically, through the arrangement of the groove 23, during the riveting process, during the cooperation process between the fastener 1 and the installation component 4, the connection position of the groove 23 and the fastener gap compensation device 2 can be elastically deformed by bending, so that the fastener gap compensation device 2 itself is easier to bend, the resistance to elastic deformation is smaller, and from the material point of view, the fastener gap compensation device 2 itself has a lower material cost. Specifically, the bottom surface of the groove 23 faces the top surface of the installation component 4. In fact, during the elastic bending process of the groove 23, the concave space at the top is used to form a concession for the flange portion 11 of the fastener 1. That is to say, the actual radial dimension of the fastener gap compensation device 2 in this embodiment is slightly larger than the radial dimension of the flange portion 11.
[0051] Example 4
[0052] See also Figure 3 In this embodiment, the fastener gap compensation device 2 is set to be C-shaped, and the radial edge of the fastener gap compensation device 2 has a positioning portion 24 flattened along a direction perpendicular to the radial direction, and the number of the positioning portions 24 is multiple. Specifically, the number of the positioning portions 24 can be set to two on both sides of the opening 22. When the horizontal push force on the fastener gap compensation device 2 is very large, the positioning portion 24 can play a role in fixing the angle to avoid the deviation of the fastener gap compensation device 2.
[0053] Example 5
[0054] See also Figure 1 and Figure 3 The fastener 1 has a mounting section 13 with a reduced radial diameter at a position adjacent to the flange portion 11. The mounting section 13 is used for the fastener gap compensation device 2 to be mounted, and the diameter of the mounting section 13 matches the diameter of the mounting groove 21. The mounting section 13 can limit the position of the fastener gap compensation device 2 in the axial direction after the fastener gap compensation device 2 is installed. In other words, the mounting section 13 itself is actually a space for accommodating the fastener gap compensation device 2, and the existence of the mounting section 13 itself 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] Example 6
[0056] See also Figure 1 The riveted portion 12 of the fastener 1 can be set as a positive direction riveted structure, which is used to rivet with the bottom plate 3 along the first direction. During the installation process of this embodiment, the riveted portion 12 of the fastener 1 is riveted from top to bottom along the first direction on the bottom plate 3.
[0057] Example 7
[0058] See also Figure 4 The riveted portion 12 of the fastener 1 can be set as a reverse riveted structure, and the reverse riveted structure is used to be riveted to the bottom plate 3 in a direction away from the first direction. In this embodiment, the riveted portion 12 of the fastener 1 is riveted from bottom to top on the bottom plate 3 in a direction away from the first direction. The reverse riveting installed on the back can improve the tensile strength and lateral thrust of the fastener 1.
[0059] Example 8
[0060] See also Figure 5 The riveting portion 12 of the fastener 1 has a tooth 14 on one side away from the riveting direction. The tooth 14 is used to assist the riveting of the fastener 1. During the riveting, part of the metal material in the base plate 3 is inserted into the tooth 14 of the fastener 1. The tooth 14 serves as a replacement for the original material storage part to achieve greater torsion resistance.
[0061] Specifically, in the above-mentioned embodiment, the position between the flange portion 11 and the rivet portion 12 of the fastener 1 is used to be inserted into the installation component 4, and the axial dimension between the flange portion 11 and the rivet portion 12 of the fastener is larger than the axial dimension of the installation component 4, thereby accommodating the placement of the fastener gap compensation device 2 itself.
[0062] Furthermore, the radial dimension of the fastener gap compensation device 2 is larger than the radial dimension of the flange portion 11 of the fastener 1. Therefore, the groove 23 of the fastener gap compensation device 2 can actually have enough space to accommodate the edge position of the flange portion 11 after deformation, avoiding mutual squeezing and generating additional wear or stress.
[0063] The contents disclosed above are only preferred feasible embodiments of the present invention, and are not intended to limit the scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention's specification and drawings are included in the scope of the present invention.
