[0025] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined purposes, the present application is described in detail as follows in combination with the accompanying drawings and preferred embodiments.

[0026] The present application provides a non-releasable fastening assembly 10, which comprises a bolt 110 and an adjusting seat 120 matched with the bolt 110. The bolt 110 comprises a bolt head and a bolt rod, and the adjusting seat 120 comprises an adjusting seat upper section and an adjusting seat bottom section. The adjusting seat upper section is provided with a long-slot through hole 121, and the width of the long-slot through hole 121 is less than the diameter of the bolt head, so that the bolt rod can pass through the long-slot through hole 121, while the bolt head is outside the long-slot through hole 121.

[0027] The adjusting seat bottom section is a hollow circular ring body, and the inner diameter of the hollow circular ring body is greater than or equal to the length of the long-slot through hole 121, so that the bolt rod can slide in the long-slot through hole 121 of the adjusting seat 120; and the outer diameter of the hollow circular ring body is less than the width of the adjusting seat upper section.

[0028] When the fastening assembly 10 is used to connect the first component and the second component, the adjusting seat 120 is installed on the first component, the bolt 110 is inserted into the adjusting seat 120, the adjusting seat 120 is rotated and the bolt 110 is slid, so that the bolt 110 is fastened to connect the second component. The first component is provided with a mounting hole matched with the hollow annular body, the hollow annular body is completely embedded and mounted in the mounting hole, and the upper segment of the adjusting seat is located above the mounting hole because the width of the upper segment of the adjusting seat is greater than the outer diameter of the hollow annular body. Therefore, the hollow annular body can rotate in the mounting hole, and the adjusting seat 120 is rotated relative to the first component without radial and axial displacement. When the adjusting seat 120 is rotated, the direction of the long slot through hole 121 is also changed, and the bolt 110 slides in the long slot through hole 121. That is, because the adjusting seat 120 can be rotated, the movable range of the bolt 110 is within the maximum circumferential range formed by the rotation of the long slot through hole 121, which greatly increases the adjustment amount during the installation of the assembly.

[0029] According to some embodiments of the present application, an outer thread is arranged on the end of the bolt rod part away from the bolt head part; the middle part of the long slot through hole 121 is a circular arc outwardly protruding to form a first inner thread matched with the outer thread, and the bolt 110 is non-fixedly connected with the adjusting seat 120 after being screwed into the adjusting seat 120 through the first inner thread. At this time, the part of the bolt rod part close to the bolt head part is not provided with an outer thread, and the bolt 110 is actually in a non-fixedly connected state with the adjusting seat 120 after being screwed into the adjusting seat 120 through the first inner thread. The bolt 110 can slide in the long slot through hole 121 and will not easily fall off. That is, when the fastening assembly 10 is used to install the first component and the second component, the bolt 110 in the fastening assembly 10 will not easily fall off due to placement problems during installation after being installed in the bottom segment of the adjusting seat.

[0030] According to some embodiments of the present application, a protrusion 122 is arranged on the outside of the bottom segment of the adjusting seat, so that the adjusting seat 120 can be fixedly clamped in the first component to be connected and is more difficult to loosen. At this time, in order to enable the bottom segment of the adjusting seat to rotate in the mounting hole, a circular groove corresponding to the protrusion 122 needs to be arranged in the mounting hole.

[0031] According to some embodiments of the present application, the upper segment of the adjusting seat is a cylinder or a regular polygon, and the bottom segment of the adjusting seat is coaxial with the upper segment of the adjusting seat. The adjusting seat 120 with axial symmetry is more stable.

[0032] The present application provides an optoelectronic system including the non-loose fastening assembly 10, the first component and the second component. The first component can be a sensor 20 or an optical device, and the second component can be a system base 30. As shown in Figure 3 The sensor 20 is installed on the system base 30 through a plurality of fastening assemblies 10.

[0033] According to some embodiments of the present invention, the first component is provided with a mounting hole that matches the bottom section of the adjusting seat. The mounting hole is a cylindrical hole, and the bottom section of the adjusting seat can rotate relative to the mounting hole, thereby causing the adjusting seat 120 to rotate relative to the first component without radial or axial displacement.

[0034] According to some embodiments of the present invention, a circular groove corresponding to the protrusion 122 is provided in the mounting hole so that the bottom section of the adjusting seat can rotate within the mounting hole.

[0035] According to some embodiments of the present invention, the second component is provided with a second mounting hole that matches the bolt 110. The bolt 110 is installed into the second mounting hole to fasten the first component and the second component. When the shank of the bolt 110 is provided with an external thread, the second mounting hole is provided with a second internal thread that matches the external thread. The bolt 110 is screwed into the second internal thread to fasten the first component and the second component.

[0036] The present invention provides a fastening method for an optoelectronic system, which uses multiple fastening components 10 to fasten a first component and a second component, including: installing multiple adjusting seats 120 into the first component respectively, inserting multiple bolts 110 into the multiple adjusting seats 120, rotating the multiple adjusting seats 120, and sliding the multiple bolts 110 to fasten the bolts 110 to the second component.

[0037] Based on the above implementation methods, a specific embodiment is described below. Figure 3 As shown, the sensor 20 is mounted onto the system base 30 using four non-loosening fastening components 10. Each of the four non-loosening fastening components 10 includes four bolts 110 and four adjusting seats 120. The four bolts 110 are respectively inserted into the four adjusting seats 120, allowing them to slide within the elongated slots of the adjusting seats 120. The four adjusting seats 120 are then respectively inserted into the four first mounting holes of the sensor 20. During the installation and adjustment process, the corresponding positions of the sensor 20 and the system base 30 are determined. Based on the actual situation, the angle of the corresponding adjusting seats 120 is rotated, and the position of the bolts 110 is adjusted so that the bolts 110 are aligned with the second mounting holes of the system base 30. The bolts 110 are then screwed into the system base 30 and tightened.

[0038] Since the fastening assembly 10 of the present application increases the adjustment allowance between the sensor 20 and the system base 30, the photoelectric system using the fastening assembly 10 of the present application can also realize the fine adjustment of the direction. For example, when the direction of the sensor 20 needs to be adjusted, the installed bolt 110 can be rotated out of the second mounting hole but retained in the adjusting seat 120, the direction of the sensor 20 is fine adjusted and determined, the relative position between the sensor 20 and the system base 30 is kept, the directions of the four adjusting seats 120 are rotated respectively and the bolt 110 is adjusted correspondingly, so that the bolt 110 can be aligned with the second mounting hole of the system base 30 and the relative position with the system base 30, the directions of the four adjusting seats 120 are rotated at a certain angle, the bolt 110 is rotated into the system base 30 and the bolt 110 is locked. After the adjustment is completed, the sensor 20 will not appear to be offset and loose in various working environments.

[0039] Through the description of the specific embodiments, the technical means and effects taken by the present application to achieve the predetermined purposes can be understood more deeply and specifically. However, the accompanying drawings are only provided for reference and illustration, and are not used to limit the present application.
