[0038] See also Figures 1 to 8 The embodiment of the present application provides an adjustment frame, including: a support part 1, a pitch adjustment part 36, a pitch control screw 31 and a connecting rod 34. The support part 1 is used to be fixed to a wall. The pitch adjustment part 36 is installed on the upper surface of the support part 1 and is used to fix the product to be installed. The rear surface of the pitch adjustment part 36 is provided with a pulling shaft, which is connected to one end of the connecting rod 34, and the other end of the connecting rod 34 is connected to the pitch control screw 31. The pitch control screw 31 is installed above the support part 1. The installation position of the pitch control screw 31 on the support part 1 is adjustable. The embodiment of the present application provides an adjustment frame, which solves the technical defect in the prior art that the installation adjustment frame of the spotlight antenna cannot be flexibly adjusted.

[0039] In the technical solution provided in the embodiment of the present application, the support part 1 is fixedly installed on the wall, providing a stable installation reference for the installation of the installation part. In the actual installation process, the support part 1 can also be fixedly installed on the roof or the ground, and the selection can be made according to the actual installation requirements. The fixed position of the support part 1 here does not constitute a limitation on the protection scope of the present application. By adjusting the installation position of the pitch control screw 31 on the support part, the connecting rod 34 is driven to move, thereby further driving the pitch adjustment part 36 connected to the other end of the connecting rod 34 to move, and the pitch angle of the pitch adjustment part 36 is adjusted.

[0040] To further optimize the technical solution, the present application provides an adjustment frame further comprising: a rotation adjustment portion 21, which is disposed on the upper surface of the support portion 1 and rotates on the upper surface of the support portion 1; the rotation adjustment portion 21 is provided with a slot, and the pulling shaft passes through the slot and is connected to the connecting rod 34. The rotation adjustment portion 21 rotates on the upper surface of the support portion 1 to adjust the rotation angle.

[0041] See further here Figure 7 , Figure 7 The structure of 35 is Figure 6 A partial enlarged schematic diagram of the structure at the dotted frame of the rotation adjustment part 21; the rotation angle and pitch angle of the product to be installed (such as a spotlight antenna) installed on the pitch adjustment part 36 are adjusted respectively through the rotation adjustment part 21 and the pitch adjustment part 36 to meet more diversified practical usage needs. In the actual installation structure, the surface of the pitch adjustment part 36 is provided with a plurality of holes, and the product to be installed is fixed to the product to be installed by bolts passing through the holes of the pitch adjustment part 36.

[0042] The rotation adjustment part 21 rotates on the upper surface of the support part 1, and the rotation of the rotation adjustment part 21 drives the pitch adjustment part 36 to rotate synchronously, so that the rotation angle of the product to be installed on the pitch adjustment part 36 can be adjusted. At the same time, the pulling shaft of the pitch adjustment part 36 passes through the slot of the rotation adjustment part 21 and is connected to one end of the connecting rod 34, and the other end of the connecting rod 34 is connected to the pitch control screw 31 installed on the rotation adjustment part 21. In the actual application process, in order to facilitate the position adjustment of the pitch control screw 31, an outwardly extending hole structure can be provided on the surface of the rotation adjustment part 21, and the pitch control screw 31 passes through the hole structure and is fixed with a fastening nut 32. When the pitch angle needs to be adjusted, the fastening nut 32 is loosened and the pitch control screw 31 is rotated to adjust. After adjusting to the preset pitch angle, the fastening nut 32 is locked. The entire pitch angle adjustment process only needs to loosen the fastening nut 32 and rotate the pitch control screw 31 to complete, and the pitch angle adjustment is more convenient.

[0043] To further optimize the technical solution, in order to facilitate the connection between the pulling shaft and the connecting rod 34, in an adjustment frame provided in an embodiment of the present application, the deflection part further includes: a sleeve 37, which is a hollow cylindrical structure, the pulling shaft is inserted into the sleeve 37, the sleeve 37 is provided with a slot, and the connecting rod 34 is inserted into the slot. The pulling shaft is inserted into the sleeve 37 and fixed with the sleeve 37, and one end of the connecting rod 34 is inserted into the slot of the sleeve 37, so that the connection and fixation of the pulling shaft and the connecting rod 34 are realized.

[0044] In the actual installation structure, in order to further improve the stability of the connection structure between the sleeve 37 and the pulling shaft, holes are provided on the sleeve 37 and the pulling shaft, and pins are inserted into the holes to further enhance the stability of the connection structure between the sleeve 37 and the pulling shaft.

[0045] Similarly, in order to improve the stability of the connection structure between the connecting rod 34 and the pitch control screw 31 while taking into account the convenience of installation of the connecting rod 34 and the pitch control screw 31, in the technical solution provided in the embodiment of the present application, the pitch adjustment part also includes: a sleeve 33, the sleeve 33 is sleeved on the outer ring of the pitch control screw 31, and the other end of the connecting rod 34 is connected to the pitch control screw 31 through the sleeve 33. When the pitch control screw 31 rotates, the stability of the connection structure between the connecting rod 34 and the pitch control screw 31 will not be affected.

[0046] In order to achieve accurate adjustment of the pitch angle, in an adjustment frame provided in an embodiment of the present application, a scale is provided on the surface of the slot. During the rotation of the pitch control screw 31, the pulling shaft is driven to shift in the slot, and the pitch angle can be adjusted correspondingly through the scale indication of the pulling shaft in the slot, thereby achieving accurate control of the pitch angle adjustment.

[0047] See further here Figure 6 In the technical solution provided by the embodiment of the present application, in order to facilitate the installation and fixation of the rotation adjustment part 21 and the adjustment of the rotation angle, the deflection part also includes: a bearing seat 24 and a bearing 23. The bearing 23 seat is installed on the upper surface of the support part 1. The rotation adjustment part 21 is installed on the bearing 23 seat through the bearing 23. The bearing 23, the rotation adjustment part 21 and the bearing 23 seat are all interference fit. The rotation of the bearing 23 drives the rotation of the rotation adjustment part 21. At the same time, the bearing 23 seat provides a stable installation foundation for the bearing 23 to prevent loosening during the rotation angle. The interference fit of the bearing 23, the rotation adjustment part 21 and the bearing 23 seat ensures smooth adjustment of the angle rotation.

[0048] In the process of actual application, in order to ensure that the rotation adjustment part 21 can be better rotated after the rotation angle adjustment is completed to prevent the rotation adjustment part 21 from rotating unpredictably; at the same time, taking into account that the rotation adjustment part 21 can be adjusted more quickly and conveniently during the angle adjustment, in an adjustment frame provided in an embodiment of the present application, a hole position is preset in the rotation adjustment part 21 and the bearing 23 seat, and the fastening bolt 22 passes through the hole position and cooperates with the fastening nut 25 to achieve the locking of the rotation adjustment part 21 and the bearing 23 seat; when the rotation angle needs to be adjusted, it is only necessary to loosen the fastening bolt 22 and the fastening nut 25 to rotate the rotation adjustment part 21, and after rotating to the preset angle, the fastening bolt 22 and the fastening nut 25 can be locked.

[0049] Similarly, in order to facilitate the precise adjustment of the rotation angle, in the technical solution provided in the embodiment of the present application, a scale indicator dial is provided on the surface of the bearing 23 seat.

[0050] See further here Figure 5 In an adjustment rack provided in an embodiment of the present application, the support part 1 includes: a base 14, a mounting platform 11 and a support rod 13; the base 14 is installed on a wall, the support part 1 is installed on the upper surface of the mounting platform 11, and the base 14 and the mounting platform 11 are connected through the support rod 13. The coordinated structure of the base 14, the mounting platform 11 and the support rod 13 has the advantages of convenient installation and stable structure; the support rod 13 can effectively support the mounting platform 11, ensuring the stability and reliability of the overall structure of the support part 1.

[0051] In actual application, in order to further enhance the load-bearing strength of the support portion 1 , a reinforcing rib structure is provided on the lower surface of the mounting platform 11 .

[0052] In actual application, in order to further enhance the supporting performance of the support rod 13 for the mounting platform 11, the number of support rods 13 is two, and the contact surfaces of the two support rods 13 with the mounting platform 11 are close to or overlapped, and the contact surfaces of the two support rods 13 with the base 14 are far away. In this way, a triangular stable structure is formed between the support rod 13 and the base 14, and the position of the support rod 13 can remain stable, thereby effectively improving the supporting performance of the support rod 13 for the mounting platform 11.

[0053] To facilitate the adjustment of the installation height, in an adjustment frame provided in an embodiment of the present application, the support portion 1 further includes: a limit screw 15, which passes through the base 14 and the mounting platform 11 respectively, and is fixed to the base 14 and the mounting platform 11. When height adjustment is required, the limit screw 15 is rotated, and the mounting platform 11 is adjusted to the position of the limit screw 15 to complete the height of the mounting platform 11, thereby realizing the adjustment of the height, rotation angle and pitch angle of the adjustment frame, and more meeting the diversified installation requirements.

[0054] In actual application, in order to lock the limit screw 15 and the mounting platform 11 to prevent displacement when no height adjustment is required, the limit screw 15 and the mounting platform 11 can be locked by the locking nut 12; similarly, when position adjustment is required, the limit screw 15 can be rotated by loosening the locking nut 12.

[0055] In actual application, in order to ensure that the mounting platform 11 can be adjusted in height smoothly and steadily, there are two limit screws 15, and the two limit screws 15 are respectively arranged on both sides of the mounting platform 11, so that the entire mounting platform 11 is evenly stressed when the position is adjusted, and there will be no deviation on one side.

[0056] In order to facilitate the installation of the support rod 13 and take into account the relative structural stability of the base 14, the mounting platform 11 and the support rod 13 during the height adjustment process, in the technical solution provided by the embodiment of the present application, the base 14 is provided with a slot, one end of the support rod 13 is connected to the slot, and the other end of the support rod 13 is connected to the lower surface of the mounting platform 11 through a rotating shaft. The support rod 13 is fixed by the slot provided in the base 14; at the same time, when the height is adjusted, due to the existence of the rotating shaft structure, the rotating shaft drives the other end of the support rod 13 to rotate with the adjustment of the height, so as to better cooperate with the smooth progress of the height adjustment.

[0057] See further here Figure 8 In order to better protect the structure to be installed on the adjustment frame and prevent the structure to be installed from falling and causing accidents in bad weather such as strong winds, an adjustment frame provided in an embodiment of the present application also includes: an anti-falling part 4, and the anti-falling part 4 includes: a chain 42, a D buckle 41 and a fixing plate 43. One end of the chain 42 is connected to the pulling shaft through the D buckle 41, and the other end of the chain 42 is fixed to the external wall through the fixing plate 43. After being fixed by the fixing plate 43, the other end of the chain 42 is connected and fixed to the pulling shaft through the D buckle 41. In this way, even if the connection structure of the support part 1 is loose in extreme weather, double protection can still be performed through the fixing plate 43 and the chain 42. When replacement or maintenance is required, only the D buckle 41 needs to be opened to replace and maintain, and the operation is simple and convenient.

[0058] In summary, the present application provides an adjustment frame, which includes: a support part, a pitch adjustment part, a pitch control screw and a connecting rod, wherein the support part is used to be fixed to a wall, and the pitch adjustment part is installed on the upper surface of the support part for fixing the product to be installed; a pulling shaft is provided on the rear surface of the pitch adjustment part, and the pulling shaft is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the pitch control screw, and the pitch control screw is installed above the support part; the installation position of the pitch control screw on the support part is adjustable. In the technical solution provided by the present application, the pitch angle is adjusted by adjusting the connection position between the connecting rod and the pitch control screw, so that the pitch angle of the product to be installed installed on the deflection part can be flexibly adjusted to meet the diverse installation requirements of different installation environments.
