[0008] In some embodiments of this application, the base includes a cylindrical body and an outward flange. The cylindrical body has a clearance groove on its wall to avoid protruding structures on the outer surfaces of the target camera and the camera to be adjusted. The guide portion is detachably connected to the outward flange. And / or, the guide portion includes an arc-shaped bent plate, the arc-shaped bent plate being provided with a guide hole.

[0009] In some embodiments of this application, a positioning block is provided on the inner surface of the cylindrical wall of the cylinder.

The positioning part is then fixed to the guide part by a fixing part. Next, the guide part and positioning part are removed from the base, the target camera is taken out, and the camera to be adjusted (i.e., the camera whose angle needs adjustment) is placed into the receiving cavity of the base. The operator simply rotates the camera around the damping pivot to align its positioning mating part with the positioning part in the target position, thus completing the precise pre-adjustment of the camera angle. The entire adjustment process is convenient and does not require climbing. The adjusted camera is directly installed in the corresponding position on the boarding bridge, improving both installation efficiency and operational safety. Attached Figure Description

[0021] See Figures 1 to 3As shown, this application provides a camera positioning pre-installation device for a boarding bridge, including a base 10, a guide 20, and an adjustment mechanism 30. The base 10 has a receiving cavity 11 for accommodating a camera 100, which can accommodate a target camera or a camera to be adjusted. Both the target camera and the camera to be adjusted have a damping pivot 102 and a positioning mating part 103. The guide 20 is detachably connected to the base 10. The adjustment mechanism 30 includes a positioning part 31, an adjustment part 32, and a fixing part 33. The positioning part 31 is connected to the adjustment part 32, and the adjustment part 32 is slidably connected to the guide 20 so that the positioning part 31 can be aligned with the positioning mating part 103 of the target camera placed in the receiving cavity 11. The fixing part 33 is used to fix the adjustment part 32 to the guide 20 so that the positioning part 31 is in the target position. The camera to be adjusted can rotate around the damping pivot 102 so that the positioning mating part 103 of the camera to be adjusted placed in the receiving cavity 11 is aligned with the positioning part 31 in the target position.

[0022] The camera positioning pre-installation device for boarding bridges provided in this application embodiment allows for precise pre-adjustment of the camera angle. First, the target camera (i.e., the pre-adjusted camera 100) is placed in the receiving cavity 11 of the base 10. Using the sliding adjustment mechanism 30, the positioning part 31 is aligned with the positioning mating part 103 of the target camera, thus placing the positioning part 31 in the target position. At this point, the fixing part 33 secures the positioning part 31 in the target position to the guide part 20. Then, the guide part 20, along with the positioning part 31, is removed from the base. The target camera is taken out, and the camera to be adjusted (i.e., the camera 100 whose angle needs adjustment) is placed in the receiving cavity 11 of the base 10. The operator only needs to rotate the camera to be adjusted around the damping pivot 102 to align its positioning mating part 103 with the positioning part 31 in the target position, thus completing the precise pre-adjustment of the camera angle. The entire adjustment process is convenient and does not require climbing. The pre-adjusted camera 100 is directly installed in the corresponding position on the boarding bridge, which not only improves installation efficiency but also enhances the safety of the operation.

[0023] It should be understood that the target camera and the camera to be adjusted are usually the same model, camera 100, see [link / reference]. Figure 4As shown, the camera 100 includes a main body 101, a damping pivot 102, a positioning mating part 103, and a mounting base 104. The main body 101 is generally hemispherical and is hinged to the mounting base 104 via the damping pivot 102, allowing manual adjustment of the angle of the main body 101. Under the action of the damping pivot 102, the main body 101 can maintain the adjusted angle. The positioning mating part 103 is connected to the main body 101; for example, the positioning mating part 103 can be an annular shape. The mounting base 104 is generally cylindrical, and the outer surface of the circumferential sidewall of the mounting base 104 can be provided with a protruding structure 105, and the bottom edge of the circumferential sidewall of the mounting base 104 can be provided with a groove. The camera 100 also includes a transparent cover, which is detachably mounted to the main body 101. The transparent cover can be a transparent glass cover. Before placing the target camera and the camera to be adjusted into the receiving cavity 11, the transparent cover needs to be removed to expose the positioning mating part 103.

[0024] Since the target camera and the camera to be adjusted are the same model, their external dimensions, spatial position and shape of the positioning and fitting part 103, and the specifications of the slot (if any) and protrusion structure 105 (if any) of the mounting base 104 are all the same. This allows the positioning part 31, which is located at the target position determined by the target camera, to be accurately fitted to the camera to be adjusted that is subsequently placed in the receiving cavity 11, avoiding mechanical interference and other problems caused by model differences, and improving the mechanical alignment accuracy of the camera 100 of the boarding bridge when it leaves the factory.

[0025] Furthermore, cameras 100 of the same model have the same focal length, field of view, and internal sensor layout. When the camera to be adjusted is aligned with the positioning part 31 at the target position within the base 10, its physical angle is not only completely consistent with the target camera, but also equivalently replicates the optimal monitoring field of view of the target camera that has been verified in the early stage. This ensures that the pre-adjusted camera 100 can achieve the expected monitoring coverage effect after subsequent high-altitude wall-mounted installation, further shortening the on-site debugging cycle.

[0026] In some embodiments, see Figure 1 and Figure 3 As shown, the positioning part 31 includes a positioning cover 311 and a rod 312. The positioning cover 311 is connected to the rod 312. The positioning cover 311 can be aligned with the positioning mating part 103 of the camera 100 located in the receiving cavity 11 and cover the positioning mating part 103. One end of the rod 312 is connected to the positioning cover 311. The rod 312 can reciprocate relative to the adjustment part 32 along its own axis.

[0027] In some embodiments, see Figures 7 to 9As shown, the positioning cover 311 includes a circular top plate 3111 and an annular sidewall 3112. The axis of the circular top plate 3111 coincides with the axis of the rod 312. The annular sidewall 3112 is fixedly connected to the circular top plate 3111 to form a positioning cavity 313. The inner diameter of the positioning cavity 313 is slightly larger than the outer diameter of the positioning mating part 103. When determining the target position of the positioning part 31, the adjusting part 32 is slid along the guide part 20 so that the positioning cover 311 is approximately above the positioning mating part 103. Then, the positioning cover 311 and the rod 312 are moved together relative to the adjusting part 32 along their own axis toward the positioning mating part 103 until the positioning cover 311 is aligned with the positioning mating part 103 of the target camera located in the receiving cavity 11 and covers the positioning mating part 103. The positioning part 31 is then fixed to the guide part 20 by the fixing part 33.

[0028] Then, the guide part 20, which has fixed the positioning part 31, is removed from the base 10 as a whole, the target camera is taken out, and the camera to be adjusted is placed in the receiving cavity 11. In order to prevent the annular sidewall 3112 of the positioning cover 311 from interfering with the positioning mating part 103 of the camera to be adjusted, before installing the guide part 20 on the base 10, the positioning part 31 is moved a certain distance away from the base 10 along the axis of the rod 312. This distance is usually greater than the axial dimension of the annular sidewall 3112. Then, the guide part 20 is installed on the base 10. Since the positioning part 31 on the guide part 20 is already in the target position, the angle of the camera to be adjusted can be manually adjusted so that the positioning mating part 103 of the camera to be adjusted is initially aligned with the positioning cover 311. Then, the positioning cover 311 and the rod 312 move together relative to the adjustment part 32 along their own axis toward the positioning mating part 103. As the positioning cover 311 and the positioning mating part 103 of the camera to be adjusted gradually approach each other, it is possible to better observe whether they are aligned. If necessary, the angle of the camera to be adjusted can be finely adjusted to ensure that the positioning mating part 103 of the camera to be adjusted is aligned with the positioning cover 311. Since the inner diameter of the positioning cavity 313 is slightly larger than the outer diameter of the positioning mating part 103, as long as at least a portion of the positioning mating part 103 along its axial direction is located within the positioning cavity 313, the two can be considered aligned.

[0029] In some embodiments, the positioning cover 311 may also be a circular plate, the diameter of which may be the same as or slightly smaller than the outer diameter of the positioning mating part 103. Therefore, when the positioning cover 311 approaches the positioning mating part 103 of the target camera, or when the positioning mating part 103 of the camera to be adjusted approaches the positioning cover 311 at the target position, the operator can directly observe from a top-down perspective whether the positioning cover 311 and the positioning mating part 103 are aligned, facilitating fine-tuning at any time and further improving work efficiency.

[0030] In a scheme where the diameter of the circular plate is the same as the outer diameter of the positioning and fitting part 103, the circumferential edge of the circular plate and the circumferential edge of the positioning and fitting part 103 basically coincide, which means that the two are considered to be aligned.

[0031] In a scheme where the diameter of the circular plate is slightly smaller than the outer diameter of the positioning and fitting part 103, it is necessary to observe and determine that the circumferential edge of the circular plate and the circumferential edge of the positioning and fitting part 103 form concentric circles, which can be considered as alignment between the two.

[0032] It should be understood that in the scheme where the positioning cover 311 is a circular plate, since the annular sidewall 3112 is omitted, the guide part 20 with the fixed positioning part 31 can be directly installed on the base 10 where the camera to be adjusted is placed. At this time, the circular plate and the positioning mating part 103 of the camera to be adjusted will not interfere with each other, thereby eliminating the step of repeatedly adjusting the positioning part 31 along the axis of the rod 312, and further improving work efficiency.

[0033] Of course, to improve safety and prevent the camera 100 from being damaged by accidental bumps, the positioning part 31 can be moved a certain distance away from the base 10 along the axis of the rod 312 before the guide part 20 is installed on the base 10. Even so, the moving distance of the positioning part 31 will be relatively small, which can still improve work efficiency.

[0034] In some embodiments, see Figure 1 As shown, the base 10 includes a cylindrical body 12 and an outwardly flanged edge 13. At least a portion of the inner cavity of the cylindrical body 12 forms a receiving cavity 11. The cylindrical wall of the cylindrical body 12 is provided with a clearance groove 121 to avoid protruding structures 105 on the outer surface of the target camera and the camera to be adjusted. The guide portion 20 is detachably connected to the outwardly flanged edge 13. The base 10 also includes an annular base plate 14, which is provided with an annular support portion 141. The annular base plate 14 is fixedly connected to the bottom of the cylindrical body 12, and the annular support portion 141 is located inside the cylindrical body 12 to support the mounting base 104 of the camera 100. For example, the annular support portion 141 is interference-fitted with the cylindrical body 12 or welded.

[0035] The number of clearance slots 121 can be one or more, and the number and location of clearance slots 121 are selected according to the specific external structure of different camera models 100. In some embodiments of this application, the number of clearance slots 121 is two. It should be understood that in order to accommodate different models of cameras 100, various sizes of bases 10 can be provided to enhance the applicability of the positioning pre-installation device.

[0036] It should be noted that the protruding structure 105 is generally located on the circumferential outer surface of the mounting base 104 of the camera 100. If there is no protruding structure 105 on the outer surface of the camera 100, the cylindrical wall of the cylinder 12 may not have an clearance groove 121.

[0037] In some embodiments, see Figure 2 As shown, a positioning block 122 is provided on the inner surface of the cylinder wall of the cylinder 12. The positioning block 122 is used to cooperate with the slot of the mounting seat 104 of the camera 100 located in the receiving cavity 11 so that the mounting seat 104 is fixed relative to the base 10.

[0038] The number of positioning blocks 122 is the same as the number of slots (not shown in the figure). For example, there is one slot and one positioning block 122. When the camera 100 is placed into the receiving cavity 11, the slot and the positioning block 122 are aligned and engaged to ensure that the mounting base 104 is fixed relative to the base 10, thereby preventing the camera 100 inside the receiving cavity 11 from rotating or shaking.

[0039] In some embodiments, see Figures 1 to 3 As shown, the guide part 20 includes a bent plate, which can be, but is not limited to, an arc-shaped bent plate 21, and the arc-shaped bent plate 21 is provided with a guide hole 211; the adjustment part 32 includes a sleeve 321, the inner wall of the sleeve 321 is provided with an internal thread, and the outer wall of the sleeve 321 is provided with an external thread; the fixing part 33 includes a first fixing plate 331, a second fixing plate 332, and a locking nut 333, the first fixing plate 331 being located on the side of the arc-shaped bent plate 21 away from the base 10, see [reference]. Figure 10 As shown, the first fixing plate 331 is provided with a first through hole 3311, the diameter of which is preferably slightly larger than the outer diameter of the sleeve 321; the second fixing plate 332 is located on the side of the arc-shaped bent plate 21 near the base 10, see [reference]. Figures 11 to 13As shown, the second fixing plate 332 is provided with a second through hole 3321, which includes a first hole portion 3322 and a second hole portion 3323. The diameter of the first hole portion 3322 is larger than the diameter of the second hole portion 3323, so as to form a stepped surface 3324 between the first hole portion 3322 and the second hole portion 3323. The first hole portion 3322 is located on the side of the second hole portion 3323 closer to the first fixing plate 331, and the first hole portion 3322 is a threaded hole. The locking nut 333 is located on the side of the first fixing plate 331 away from the second fixing plate 332. The sleeve 321 passes through... The first through hole 3311 has an external thread that connects to the first hole 3322, and the sleeve 321 abuts against the stepped surface 3324. The rod 312 has an external thread and passes through the second through hole 3321, the guide hole 211, and the first through hole 3311. The internal thread of the sleeve 321 engages with the external thread of the rod 312, allowing the rod 312 to reciprocate along its own axis. The locking nut 333 is connected to the external thread of the sleeve 321 to clamp and fix the first fixing plate 331 and the second fixing plate 332 to both sides of the arc-shaped bent plate 21. (See also...) Figure 10 and Figure 11 As shown, the surfaces of the first fixing plate 331 and the second fixing plate 332 facing the arc-shaped bending plate 21 are respectively curved surfaces adapted to the arc-shaped bending plate 21.

[0040] See Figure 6 As shown, the guide hole 211 is a strip-shaped hole extending along the arc-shaped bent plate 21. The guide part 20 also includes two mounting plates 22, which are fixedly connected to both ends of the arc-shaped bent plate 21 respectively. For example, the mounting plates 22 and the arc-shaped bent plate 21 are integrally formed. The mounting plates 22 are detachably connected to the outer flange 13. When the rod 312 moves along the guide hole 211, the axis of the rod 312 has a first motion trajectory. When the camera 100 in the receiving cavity 11 rotates around the damping shaft 102, the axis of the positioning mating part 103 has a second motion trajectory. The installation position of the mounting plate 22 on the outer flange 13 should satisfy the following: the first motion trajectory and the second motion trajectory are in the same plane. This ensures that after adjustment, the positioning part 31 and the positioning mating part 103 are coaxially aligned.

[0041] The target camera is placed into the receiving cavity 11, with the protruding structure 105 corresponding to the clearance groove 121 and the positioning block 122 corresponding to the slot. The locking nut 333 is loosened, so that the first fixing plate 331 and the second fixing plate 332 are not clamped to the arc-shaped bending plate 21, allowing the adjustment mechanism 30, including the rod 312, to move along the guide hole 211. This positions the positioning cover 311 above the positioning mating part 103 of the target camera. Then, the locking nut 333 is tightened, clamping the first fixing plate 331 and the second fixing plate 332 to both sides of the arc-shaped bending plate 21, thus fixing the position of the sleeve 321. At this point, the rod 312 is rotated. Because the external thread of the rod 312 engages with the internal thread of the sleeve 321, the rod 312 and the positioning cover 311 move together along their own axis towards the positioning mating part 103 until the positioning cover 311 aligns with the positioning mating part 103 of the target camera. At this point, the positioning cover 311 is in the target position.

[0042] It should be understood that during the process of positioning the positioning cover 311 above the positioning mating part 103 of the target camera, the operator usually observes directly, which may result in deviation. As the positioning cover 311 gradually moves closer to the positioning mating part 103, if it is found that the positioning cover 311 is deviating from the positioning mating part 103, the locking nut 333 can be loosened again to make a fine adjustment to the position of the positioning cover 311, so as to ensure that the positioning cover 311 is aligned with the positioning mating part 103 of the target camera. In the scheme where the positioning cover 311 has a positioning cavity 313, the positioning cover 311 is moved until the positioning mating part 103 is accommodated in the positioning cavity 313.

[0043] To prevent the positioning cover 311 from interfering with the positioning mating part 103 of the target camera, the rod 312 can be rotated in the opposite direction to move the positioning cover 311 away from the positioning mating part 103. Then, the guide part 20, which fixes the positioning part 31, can be removed from the base 10 as a whole, and the target camera can be taken out.

[0044] Then, place the camera to be adjusted into the receiving cavity 11, ensuring that the protruding structure 105 corresponds to the clearance groove 121 and the positioning block 122 corresponds to the slot. Next, fix the mounting plate 22 to the outward-facing flange 13. Manually adjust the angle of the camera to be adjusted so that the positioning mating part 103 of the camera is initially aligned with the positioning cover 311 at the target position. Then, rotate the rod 312 so that the rod 312 and the positioning cover 311 move together along their own axis towards the positioning mating part 103. As the positioning cover 311 and the positioning mating part 103 of the camera to be adjusted gradually approach each other, it is easier to observe whether they are aligned. If necessary, the angle of the camera to be adjusted can be finely adjusted to ensure that the positioning mating part 103 of the camera to be adjusted is aligned with the positioning cover 311. At this point, the angle adjustment of the camera to be adjusted is complete.

[0045] Then, rotate the rod 312 in the opposite direction so that the positioning cover 311 is away from the camera 100 with the angle adjusted, separate the mounting plate 22 from the outer flange 13, take out the camera 100 with the angle adjusted, and install the transparent cover. This completes the pre-installation work of adjusting the position of the camera 100, so that when the camera 100 is installed on the boarding bridge at the airport, it can be installed in place in one go without further adjustment, effectively reducing labor costs, improving work efficiency and the safety of the installation process.

[0046] The camera positioning pre-installation device for boarding bridges provided in this application embodiment is simple to operate, reusable, and helps to reduce production costs.

[0047] It should be noted that the structure of the adjusting part 32 is not limited to the above one. Any adjusting part 32 that can enable the positioning part 31 to slide along the guide hole 211 and reciprocate along its own axis falls within the protection scope of this application. The structure of the fixing part 33 is not limited to the above one. Any fixing part 33 that can fix the positioning part 31 falls within the protection scope of this application.

[0048] In some embodiments, see Figure 1 As shown, the fixing part 33 also includes an auxiliary locking nut 334, which is located at the end of the sleeve 321 away from the positioning cover 311, and is threadedly connected to the rod body 312.

[0049] To facilitate the rotation of the rod 312, when the sleeve 321 rotates to abut against the stepped surface 3324, the end of the rod 312 away from the positioning cover 311 will extend and protrude outside the sleeve 321. To prevent accidental operation of the rod 312, an auxiliary locking nut 334 is screwed onto the protruding part of the rod 312. For example, there are two auxiliary locking nuts 334. When the rod 312 does not need to be rotated, the auxiliary locking nuts 334 are tightened to abut against the sleeve 321; when the rod 312 needs to be rotated for adjustment, the auxiliary locking nuts 334 are loosened to a certain distance from the sleeve 321 or removed.

[0050] In some embodiments, see Figures 1 to 3 As shown, the camera positioning pre-installation device for the boarding bridge also includes a bolt 40 and a nut 50; the outer flange 13 is provided with a first mounting hole 131, and the guide portion 20 is provided with a second mounting hole 221. Specifically, the second mounting hole 221 is located on the mounting plate 22; the bolt 40 passes through the first mounting hole 131 and the second mounting hole 221, and the nut 50 is threadedly connected to the bolt 40 to fix the mounting plate 22 to the outer flange 13. When it is necessary to disassemble the guide portion 20, the nut 50 can be separated from the screw.

[0051] When the position of the slot or protrusion structure of different models of camera 100 changes, camera 100 needs to rotate a certain angle around the axis of cylinder 12 to be installed in receiving cavity 11. After camera 100 rotates, the position of its damping shaft 102 also changes, and the second movement trajectory of the positioning mating part 103 axis also changes. At this time, it is necessary to change the position of guide part 20 so that when rod 312 moves along guide hole 211, the first movement trajectory of rod 312 axis and the second movement trajectory of positioning mating part 103 axis are coplanar. (See also...) Figure 5 As shown, there are multiple first mounting holes 131, which are spaced apart circumferentially along the outer flange 13. This allows the guide portion 20 to be connected to the first mounting holes 131 at different positions, thereby changing the mounting position of the guide portion 20.

[0052] In some embodiments, the first mounting hole 131 is an arc-shaped hole, and for example, the number of arc-shaped holes is four. The second mounting hole 221 is a round hole.

[0053] In other embodiments, the first mounting hole 131 may also be a circular hole, with multiple circular holes spaced apart circumferentially along the outer flange 13.

[0054] In other embodiments, the number of first mounting holes 131 may also be one.

[0055] In some embodiments, see Figure 1 and Figure 3 As shown, the camera positioning pre-installation device for the boarding bridge also includes a pad 60, which is connected to the outer flange 13. The pad 60 is provided with a threaded through hole 61, and the bolt 40 passes through the first mounting hole 131 and the second mounting hole 221 and is connected to the threaded through hole 61.

[0056] By connecting the pad 60 to the outer flange 13, the bolt 40 passes through the mounting hole and connects with the threaded through hole 61 of the pad 60, thus achieving the pre-positioning of the bolt 40 on the outer flange 13. When it is necessary to disassemble the guide part 20, there is no need to remove the bolt 40 from the outer flange 13. Simply separate the nut 50 from the bolt 40 to directly remove the guide part 20, while the bolt 40 remains in its original position, further simplifying the disassembly and assembly process and improving work efficiency.

[0057] In some embodiments, the pad 60 is welded to the outer flange 13. The pad 60 can be welded to the upper surface of the outer flange 13 or to the lower surface of the outer flange 13.

[0058] In some embodiments, the pad 60 is detachably connected to the outer flange 13, and the threaded through hole 61 can correspond to the first mounting hole 131 at different positions so that the relative position of the guide portion 20 and the clearance groove 121 is adjustable.

[0059] As previously mentioned, when the position of the slot or protrusion structure of different models of camera 100 changes, the camera 100 needs to be rotated a certain angle around the axis of the cylinder 12 to be installed in the receiving cavity 11. At this time, the position of the guide part 20 also needs to be changed accordingly. Since the pad 60 and the outer flange 13 are detachably connected, the pad 60 can be installed in the position corresponding to the mounting plate 22. Thus, even if the position of the guide part 20 changes, the threaded through hole 61 on the pad 60 can still play a pre-positioning role for the bolt 40, thereby taking into account both the flexibility and convenience of the operation process.

[0060] In some embodiments, the positioning block 122 is detachably connected to the inner wall of the cylinder 12, so that the position of the positioning block 122 can be changed to adapt to the slots of different models of cameras 100. In some embodiments, by adjusting the position of the positioning block 122, the position of the guide portion 20 can be kept constant.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
