[0038] See also Figures 1 to 3 , a sliding adjustment module, including: a guide rail 1 and a sliding adjustment component 2.

[0039] The sliding adjustment assembly 2 is slidably mounted on the guide rail 1 and can be fixed to the guide rail 1. The sliding adjustment assembly 2 includes an upper guide plate 21 and a lower guide plate 22, which are connected by a plurality of bolts 23. The bottom surface of the upper guide plate 21 abuts the outer side of the top surface of the guide rail 1, and the top surface of the lower guide plate 22 abuts the inner side of the top surface of the guide rail 1. The bolts 23 adjust the distance between the upper guide plate 21 and the lower guide plate 22 to adjust the sliding adjustment assembly 2 to loosen or clamp the switch guide rail 1. Specifically, the guide rail 1 includes a mounting base 15 and an end cap 16. Several mounting bases 15 are spaced along the length of the guide rail 1 and are fixedly mounted on a workbench or the ground. The end cap 16 is fixed to the end of the guide rail 1 with screws to protect objects placed in the guide rail 1 and prevent foreign objects from entering the guide rail 1.

[0040] The utility model relates to a sliding adjustment module. When in use, the sliding adjustment component 2 is inserted into the end of the guide rail 1, and the sliding adjustment component 2 is moved and slid to a predetermined position along the guide rail 1. After reaching the ideal position, the bolt 23 is tightened so that the upper guide plate 21 and the lower guide plate 22 are in close contact with the surface of the guide rail 1, limiting the movement of the sliding adjustment component 2 in the vertical direction. The upper guide plate 21 and the lower guide plate 22 are both installed in the guide rail 1, and the inner wall of the guide rail 1 limits the horizontal movement of the sliding adjustment component 2. By rotating the bolt 23, the upper guide plate 21 and the lower guide plate 22 generate friction with the surface of the guide rail 1. The friction limits the movement of the sliding adjustment component 2 along the length direction of the guide rail 1 and other directions. The sliding adjustment component 2 is firmly installed on the guide rail 1, and the sliding adjustment component 2 cannot slide at this time. After the sliding adjustment component 2 is fixedly installed, the end cover 16 is fixedly installed at the end of the guide rail 1. When it is necessary to fine-tune the position of the sliding adjustment assembly 2, loosen the bolts 23. At this time, the upper guide plate 21 and the lower guide plate 22 are out of close contact with the surface of the guide rail 1, and the sliding adjustment assembly 2 can slide on the guide rail 1. Preferably, there are four groups of bolts 23, which are respectively arranged at the four corners of the sliding adjustment assembly 2.

[0041] See also Figures 1 to 3 Furthermore, the guide rail 1 includes an outer guide rail 11 and an inner guide rail 12. The inner guide rail 12 is mounted within the outer guide rail 11, with the upper surface of the inner guide rail 12 lower than the upper surface of the outer guide rail 11. The upper guide plate 21 includes a first guide plate 211 and a second guide plate 212. The bottom surface of the first guide plate 211 abuts against the surface of the outer guide rail 11, while the bottom surface of the second guide plate 212 abuts against the surface of the inner guide rail 12. Specifically, the distance from the upper surface of the inner guide rail 12 to the upper surface of the outer guide rail 11 is the same as the thickness of the second guide plate 212, and the width of the second guide plate 212 is the same as the width of the inner guide rail 12. A first guide plate 211 is mounted on the outer guide rail 11, while a second guide plate 212 is mounted on the inner guide rail 12. When an object 5 is placed on the slide adjustment assembly 2, the stress experienced by the slide adjustment assembly 2 is dispersed across both the outer and inner guide rails 11, 12. Failure of either the outer or inner guide rails 11, 12 will not affect the movement of the slide adjustment assembly 2 on the guide rail 1. Several weight-reducing grooves are provided along the length of the inner guide rail 12 to reduce its weight.

[0042] See also Figures 1 to 3 Furthermore, a gap 13 is defined between the inner guide rail 12 and the outer guide rail 11. First slides 213 are provided on both sides of the second guide plate 212 to engage with the gap 13. The first slides 213 slide along the gap 13. Specifically, the distance between the inner walls of the two first slides 213 is slightly greater than the width of the inner guide rail 12. The sliding adjustment assembly 2 slides directionally within the guide rail 1. The first slides 213 and the gap 13 restrict the movement of the sliding adjustment assembly 2 along the width direction of the inner guide rail 12.

[0043] See also Figures 1 to 3Furthermore, the top of the inner guide rail 12 is bent inward to form a slide groove 121, and the lower guide plate 22 is bent upward to form a second slide 221. The second slide 221 moves along the slide groove 121. Specifically, the combination of the slide 221 and the slide groove 121, together with the gap 13 and the first slide 213, restricts the movement of the sliding adjustment assembly 2 along the width direction of the inner guide rail 12, further ensuring that the sliding adjustment assembly 2 will not detach from the guide rail 1.

[0044] See also Figure 3 Furthermore, in the first embodiment, the lower guide plate 22 is provided with a threaded through-hole that engages with a bolt 23. This threaded engagement adjusts the spacing between the upper and lower guide plates 21, 22. Restricted by the inner guide rail 12 and the guide slot 121, the lower guide plate 22 does not rotate with the bolt 23 when the bolt 23 is turned, thereby adjusting the spacing between the upper and lower guide plates 21, 22 and the degree of contact between the upper and lower guide plates 21, 22 and the guide rail 1. When the bolt 23 is turned upward, the distance between the upper and lower guide plates 21, 22 increases, allowing the sliding adjustment assembly 2 to move freely. When the bolt 23 is turned downward, the distance between the upper and lower guide plates 21, 22 decreases, and the sliding adjustment assembly 2 is now securely fixed to the guide rail 1.

[0045] See also Figure 2 In the second embodiment, the lower guide plate 22 is further provided with a through hole 222. A nut 24 is provided in the through hole 222, which is coaxial with the through hole 222 and engages with the bolt 23. The bolt 23 is threadedly engaged with the nut 24 to adjust the distance between the upper guide plate 21 and the lower guide plate 22. The difference from the first embodiment is that the bolt 23 is threadedly engaged with the nut 24 to adjust the distance between the upper guide plate 21 and the lower guide plate 22.

[0046] See also Figures 1 to 3 Furthermore, the guide rail 1 further includes a guide rail cover 14, which covers the guide rail 1. Preferably, the guide rail cover 14 covers between adjacent first guide plates 21, and the length of the first guide plates 21 is sufficient to adjust the position of the camera mounting bracket along the guide rail 1. That is, one end of the guide rail cover 14 overlaps with the first guide plate 21 to a certain extent. After adjustment, there is no need to replace the guide rail cover 14 due to the length of the guide rail cover 14.

[0047] See also Figures 1 to 3Furthermore, the guide rail cover 14 is provided with reinforcing ribs 141 at intervals along its axial direction, and the reinforcing ribs 141 are provided with spring sheets 142, which abut against the inner wall of the guide rail 1. Preferably, a guide rail cover 14 is installed between the edges of adjacent camera mounting brackets, and the reinforcing ribs 141 are U-shaped and fixed to the inner wall of the top surface of the guide rail cover 14 by welding. When in use, the guide rail cover 14 covers the opening of the guide rail 1, and the spring sheets 142 are elastically pressed against the inner wall of the inner guide rail 13. If there is no external force, the guide rail cover 14 is fixed to the guide rail 1. If the guide rail cover 14 needs to be removed, the guide rail cover 14 is opened with force from one end of the guide rail cover 1, and the friction between the spring sheets 142 and the inner wall of the inner guide rail 12 is overcome to remove the guide rail cover 14.

[0048] See also Figure 4 and Figure 5 A mounting bracket includes a sliding adjustment module and a lifting component 3, wherein the lifting component 3 is installed on the sliding adjustment module.

[0049] See also Figure 4 and Figure 5 Furthermore, the lifting assembly 3 includes a fixed tube 31, a sliding tube 32, and a positioning pin 33. The sliding tube 32 extends and retracts along the fixed tube 31. A first positioning hole 311 is defined at the upper end of the fixed tube 31. The sliding tube 32 is provided with a plurality of first matching holes 321 along its length that mate with the first positioning hole 311. The positioning pin 33 is inserted into the first positioning hole 311 and the first matching holes 321. Specifically, the fixed tube 31 and the sliding tube 32 are square tubes, and the angle adjustment assembly 4 is mounted on the top of the sliding tube 32. The diameter of the first positioning hole 311 is larger than that of the first matching holes 321. Preferably, the first positioning hole 311 is a slot extending along the length of the fixed tube 31. The sliding tube 32 is provided with a groove 322, with the first matching holes 321 evenly spaced along the length of the groove 322. When the desired height is reached, the positioning pin 33 is inserted through the first positioning hole 311, the groove 322, and the first matching holes 321. At this point, the sliding tube 32 is fixed relative to the groove. When the height needs to be adjusted, the positioning pin 33 can be removed for adjustment. Preferably, the first positioning hole 311 is provided with two groups, thereby expanding the adjustment height. Preferably, the lifting assembly 3 is vertically mounted on the sliding adjustment module.

Mounting plate 41 is rotatably mounted within mounting box 42, and object 5 is rotatably mounted on mounting plate 41. Specifically, mounting box 42 is mounted to the end of lifting assembly 3. Mounting box 42 rotates horizontally around lifting assembly 3, while object 5 rotates horizontally around mounting plate 41. Mounting plate 41 rotates vertically around mounting box 42, allowing object 5 to be positioned horizontally and at different elevations to suit specific application scenarios.

[0052] See also Figure 6 The angle adjustment assembly 4 also includes a fixing plate 43. The bottom of the mounting box 42 is provided with a plurality of first arcuate grooves 421 arranged on the same circumference. The fixing plate 43 is provided with second positioning holes 431 that mate with the first arcuate grooves 421. Specifically, the fixing plate 43 is fixed to the top of the sliding tube 32 by welding. The plurality of second positioning holes 431 are also arranged on the same circumference. This ensures that when the mounting box 42 is rotated, the second positioning holes 431 always coincide with the first arcuate grooves 421. After achieving the horizontal rotation angle, the mounting box 42 is secured to the lifting assembly 3 using a first screw. To adjust the angle of the mounting box 42, the first screw is loosened and tightened. Preferably, there are four second positioning holes.

[0053] See also Figure 7 The mounting plate 41 is provided with a third positioning hole 411 and a second arc groove 412. The bottom of the object 5 is provided with a second matching hole 51 that cooperates with the third positioning hole 411, and the bottom of the object 5 is provided with a third matching hole 52 that cooperates with the second arc groove 412. Specifically, the distance from the second matching hole 51 to the third matching hole 52 is equal to the distance from the third positioning hole 411 to the second arc groove 412. During use, the object 5 is first initially mounted on the mounting plate 41 by inserting a second screw through the third positioning hole 41 and the third matching hole 52. The angle of the object 5 is adjusted horizontally according to actual needs. The object 5 is then secured by inserting a third screw through the second arc groove 412 and the second matching hole 51. Finally, the third screw is tightened to secure the object 5 to the mounting plate 41.

[0054] See also Figure 6 and Figure 7The side surface of the mounting box 42 is provided with a fourth positioning hole 423 and a third arc groove 422, and the mounting plate 41 is provided with a first mounting hole 413 that matches the fourth positioning hole 423, and a second mounting hole 414 that matches the third arc groove 422. Specifically, plate ears 415 are provided on both sides of the mounting plate 41, and the first mounting hole 413 and the second mounting hole 414 are provided on the plate ears 415. During use, the mounting plate 41 is first initially mounted on the mounting box 42 with a fourth screw passing through the fourth positioning hole 423 and the first mounting hole 413. According to actual needs, the angle of the mounting plate 41 is adjusted vertically, and then the fifth screw is passed through the third arc groove 422 and the second mounting hole 414 to fix the mounting plate 41. Finally, the fifth screw is tightened to fix the mounting plate 41 to the mounting box 42, thereby determining the pitch angle of the placed object 5.

[0055] The sliding adjustment module and mounting bracket of the present invention have a sliding adjustment assembly 2 that is mounted within the guide rail 1. When the sliding adjustment assembly 2 reaches a preset position, the sliding adjustment assembly 2 is fixed within the guide rail 1.
