Description

Technical Field

[0001] The present disclosure relates to the technical field of connection structures, and in particular to a fastener mounting seat and a fastening structure. Background Art

[0002] Screws are the most common way to connect two parts (components), and the premise is that matching mounting holes and threaded holes are processed on the parts (components). There are usually multiple mounting holes or threaded holes on the parts (components), but due to errors in the processing of mounting holes or threaded holes, there will be certain errors in the relative positions of mounting holes and threaded holes during installation. As a result, the screws cannot be installed due to hole position deviation during installation.

[0003] To solve the above problems, the method of enlarging the through hole diameter or processing special-shaped holes is often used to ensure installation. However, the enlarged through hole or special-shaped hole provides a movement gap for the relative displacement of the parts in the connection interface, so that when subjected to vibration along the in-plane direction of the connection interface, the high-precision positional relationship between the two will no longer exist, which is intolerable for reference parts, optical component supports, etc. Or the method of filling the above movement gap with structural glue, but this will make the structure no longer adjustable, affecting the reuse and disassembly processability of the parts.

In addition, the use of words such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, when referring to the drawings in the following description, the same symbols in different drawings represent the same elements. It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0032] According to an exemplary embodiment of the present disclosure, referring to Figures 1 to 7 As shown, a fastener mounting seat is provided, which is used to install a fastener 30 connecting a first connecting member 10 and a second connecting member 20 in a fastening hole 101 on at least one of the first connecting member 10 and the second connecting member 20. The fastener mounting seat includes a mounting seat body 1, and the mounting seat body 1 has a columnar mounting portion 11 for inserting into the fastening hole 101, and is constructed to be adjustable along the circumferential position of the fastening hole 101. An adjustment long hole 2 is opened on the mounting seat body 1, and the adjustment long hole 2 passes through the mounting seat body 1 along the axial direction of the fastening hole 101 for the fastener 30 to pass through, and the adjustment long hole 2 extends along the radial direction of the fastening hole 101.

[0033] Through the above technical solution, in the fastener mounting seat provided by the present disclosure, the projection of the fastening hole 101 of one of the first connector 10 and the second connector 20 is placed within the projection range of the fastening hole 101 of the other. When it is necessary to install the fastener 30 on at least one of the first connector 10 and the second connector 20 through the fastener mounting seat, the columnar mounting portion 11 can be first inserted into the fastening hole 101 of one of the first connector 10 and the second connector 20, and when the fastening hole 101 of the other corresponds to the adjustment long hole 2, the fastener 30 can be inserted into the fastening hole 101 through the adjustment long hole 2 to connect the first connector 10 with the second connector 20. In this way, by setting the adjustment long hole 2, when the fastening hole 101 is within the long diameter range of the adjustment long hole 2, the connection of the fastener 30 can be achieved. When the fastening hole 101 on the other of the first connecting member 10 and the second connecting member 20 deviates from the adjusting long hole 2, so that the fastener 30 cannot be inserted into the fastening hole 101 through the adjusting long hole 2, the mounting seat body 1 can be rotated circumferentially so that the adjusting long hole 2 can correspond to the position of the fastening hole 101, that is, when the projection of the fastening hole 101 is re-placed within the range of the adjusting long hole 2, the mounting seat body 1 is fixed at this time, and the fastener 30 is connected to the fastening hole 101 through the adjusting long hole 2. In this way, by providing a columnar mounting portion 11 that is adjustable along the circumference of the fastening hole 101, the fastener 30 can be connected through the fastener mounting seat for deviations of the fastening hole 101 in different directions. The problem of affecting the installation effect of the fastener 30 due to the hole position deviation is solved.

[0034] In some embodiments of the present disclosure, the fastening hole 101 may be a threaded hole, and the fastener 30 may be configured as a screw, so that the fastener 30 is threadedly connected to the fastening hole 101 , thereby connecting the first connector 10 and the second connector 20 .

[0035] In some embodiments of the present disclosure, Figures 1 to 5 As shown, a flange portion 12 is provided at one end of the columnar mounting portion 11 away from the fastening hole 101, so as to support the mounting seat body 1 in the circumferential direction of the fastening hole 101. In this way, on the one hand, the columnar mounting portion 11 can be installed in the fastening hole 101 or removed from the fastening hole 101 through the flange portion 12, thereby improving the convenience of disassembly and assembly of the fastener mounting seat. On the other hand, the fastener mounting seat can be supported by the flange portion 12 to prevent the columnar mounting portion 11 from sinking into the fastening hole 101.

[0036] In some embodiments of the present disclosure, Figure 4 and Figure 5As shown, the adjustment slot 2 is a countersunk hole structure, which includes a main hole section 21 and a countersunk section 22. The countersunk section 22 is connected to the main hole section 21 and is used to accommodate the head 301 of the fastener 30. When the rod 302 of the fastener 30 extends into the main hole section 21 to be connected to the fastening hole 101, the head 301 of the fastener 30 can be placed in the countersunk section 22. While ensuring the flatness of the connection surface of the fastener 30, the fastener 30 is limited by the hole wall of the countersunk section 22 to prevent it from moving or deflecting under the action of external force, thereby further ensuring the stability of the connection structure.

[0037] In some embodiments of the present disclosure, Figure 2 As shown, the hole wall of the countersunk section 22 is formed as a tapered guide wall extending toward the main hole section 21. By setting the hole wall of the countersunk section 22 as a tapered guide wall, the head 301 of the fastener 30 can be better embedded in the countersunk section 22, and provide additional support during the fastening process. At the same time, the countersunk section 22 can adapt to the heads 301 of fasteners 30 of different sizes, thereby increasing the applicable range of the fastener mounting seat to the fastener 30.

[0038] In some embodiments of the present disclosure, Figure 4 and Figure 5 As shown, the fastening hole 101 of the fastener mounting seat is a round hole, and the major diameter of the adjusting slot 2 is not less than the aperture of the fastening hole 101. In this way, the fastener 30 can pass through the adjusting slot 2 to connect all fastening holes 101 that fall within the range of the fastening hole 101 of the fastener mounting seat.

[0039] In some embodiments of the present disclosure, Figure 4 and Figure 5 As shown, the columnar mounting portion 11 is a cylindrical structure, and the length of the columnar mounting portion 11 is not greater than the length of the fastening hole 101 in which the columnar mounting portion 11 is installed. The columnar structure is set to match the fastening hole 101 of the round hole, so that the columnar mounting portion 11 of the fastening hole 101 can be directly rotated in the fastening hole 101, avoiding the need to take out the fastening hole 101 and then adjust the angle, thereby improving the installation efficiency. And because the length of the columnar mounting portion 11 is not greater than the length of the fastening hole 101 in which it is installed, it is easy to take out the columnar mounting portion 11.

[0040] In some embodiments of the present disclosure, Figure 6 As shown, the adjusting slot 2 is a waist-shaped hole, and the short diameter of the waist-shaped hole matches the rod 302 of the fastener 30. In this way, on the one hand, it is convenient for the fastener 30 to extend into the adjusting slot 2, and on the other hand, it is convenient for the head 301 of the fastener 30 to abut against the hole circumference of the adjusting slot 2 to achieve the fixation of the fastener 30. The reliability of the connection between the first connecting member 10 and the second connecting member 20 is ensured.

[0041] Below, reference Figures 1 to 5As shown, the present disclosure will make a detailed introduction to the specific use process of the fastener mounting seat in combination with the above-mentioned specific implementation methods. The first connecting member 10 corresponds to the second connecting member 20, and the projection of the fastening hole 101 in the second connecting member 20 is placed within the projection range of the fastening hole 101 of the first connecting member 10. In this way, the fastener mounting seat is rotated to adjust the direction of the adjustment long hole 2 on the columnar mounting portion 11, so that the fastening hole 101 on the second connecting member 20 corresponds to the adjustment long hole 2 and is placed within the projection range of the adjustment long hole 2. At this time, the columnar mounting portion 11 is extended from the fastening hole 101 of the first connecting member 10 until the flange portion 12 abuts against the first connecting member 10 to realize the installation of the fastener mounting seat, and the fastener 30 is inserted into the fastener mounting seat, and passes through the adjustment long hole 2 and the fastening hole 101 on the second connecting member 20 in turn to realize the connection and fixation of the first connecting member 10 and the second connecting member 20. If the fastener 30 cannot pass through the adjustment slot 2 and be installed in the fastening hole 101, the cylindrical mounting portion 11 of the cylindrical structure is rotated so that the adjustment slot 2 can completely correspond to the fastening hole 101 on the second connecting member 20, and the fastener 30 can pass through the adjustment slot 2 and be installed in the fastening hole 101 on the second connecting member 20. Therefore, when the hole positions of the first connecting member 10 and the second connecting member 20 deviate, the hole position deviation in any direction can be corrected by the fastener mounting seat to achieve direct connection between the first connecting member 10 and the second connecting member 20.

[0042] According to the second aspect of the present disclosure, Figures 1 to 6 As shown, a fastening structure is provided, comprising a first connecting member 10 and a second connecting member 20, wherein the first connecting member 10 and the second connecting member 20 are respectively provided with fastening holes 101, and the fastening structure further comprises a fastener 30 and at least one fastener mounting seat as described above.

[0043] In some embodiments of the present disclosure, reference Figure 7 As shown, two fastener mounting seats are provided in the same fastening hole 101, and the two fastener mounting seats are respectively inserted from both ends of the fastening hole 101. The two fastener mounting seats are installed at both ends of the same fastening hole 101, and one fastener 30 is placed between the first connecting member 10 and the second connecting member 20, so that the first connecting member 10 and the second connecting member 20 can be leveled by the flange portion 12 of the fastener mounting seat, so as to avoid wear and other conditions caused by unevenness between the first connecting member 10 and the second connecting member 20, and improve the fault tolerance rate when the first connecting member 10 and the second connecting member 20 are connected.

[0044] In some embodiments of the present disclosure, reference Figure 7As shown, the first connector 10 and the second connector 20 are both plate-like structures, each of which is provided with a plurality of fastening holes 101, and a fastener mounting seat is installed in each fastening hole 101. The fastener mounting seat is used to mount a plurality of fasteners 30 to connect the first connector 10 and the second connector 20.

[0045] In some embodiments of the present disclosure, the plane of the flange portion 12 of the fastener mounting seat placed between the first connecting member 10 and the second connecting member 20 can cooperate with the uneven plane on the plate-like structure to improve the flatness between the first connecting member 10 and the second connecting member 20.
