[0002] A photovoltaic panel is a power generation device that generates direct current when exposed to sunlight. It mainly generates electricity by absorbing solar energy through solar photovoltaic modules. It is almost entirely composed of thin solid photovoltaic cells made of semiconductor materials. During the installation process, photovoltaic panels usually need to be installed using lifting hooks.

[0003] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

[0004] Most of the existing lifting hooks are composed of an iron frame and a hoop fixed with bolts, which makes it inconvenient to rotate the tilt angle of the photovoltaic panel by rotation. In addition, in the existing technology, the installation iron frame is mostly designed with two hoops fixedly connected by the installation iron frame, which makes it inconvenient to adjust the distance between the two hoops. When the installed photovoltaic panel is heavy, the hoop is subjected to greater stress, which easily leads to a decrease in the service life of the hoop.

[0005] Therefore, those skilled in the art provide a lifting hook with adjustable angle to solve the problems raised in the above background technology. Utility Model Content

[0012] Furthermore, the two double-headed screws are respectively threaded through the centers of both sides of the upper end surfaces of the two hoop rings, and the two transverse bevel gears are respectively meshed with the two longitudinal bevel gears.

[0013] Furthermore, a positioning hole is opened through the front end of one side of the two rotating arms, and a through groove is opened through the center of both sides of the outer wall of the two sleeves.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model proposes an angle-adjustable lifting hook, which rotates the No. 1 bevel gear to drive the two No. 2 bevel gears to rotate in opposite directions at the same time, thereby driving the two threaded rods to rotate in opposite directions at the same time, and then driving the two slides to move in opposite or opposite directions at the same time, so that the two embedded blocks can respectively penetrate or escape from the two through grooves and one of the multiple positioning holes on the sleeve block and the rotating arm on the same side, so as to achieve the effect of fixing the positions of the two sleeve blocks, thereby limiting the rotation of the support arm, so that the support arm can support the rotated rotating arm, and thereby the inclination angle of the installed photovoltaic panel can be adjusted and fixed.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 4 , an embodiment provided by the utility model:

[0027] An angle-adjustable lifting hook comprises two fixed plates 1 and two hoops 4. The outer walls of the two hoops 4 are slidably disposed on both sides within the two fixed plates 1. A double-headed screw 3 is rotatably disposed at the center of the lower end surfaces of the inner walls of the two fixed plates 1. An adjustment box 2 is fixedly disposed on the upper end surfaces of the outer walls of the two fixed plates 1. An adjustment mechanism 11 is disposed within the adjustment box 2. A rotating arm 5 is rotatably disposed at the center of the outer walls of the two fixed plates 1 on one side thereof.

[0028] The outer walls of the two rotating arms 5 are movably sleeved with sleeve blocks 8, and a connecting block 7 is fixedly provided at the center of the opposite side of the outer walls of the two sleeve blocks 8. A fixing mechanism 15 is provided inside the connecting block 7, and a fixing box 6 is fixedly provided at the center of the upper end surface of the outer wall of the connecting block 7. The outer walls of the two fixed plates 1 are rotatably provided with support arms 10 at the center of the separated side, and one end of the two support arms 10 is rotatably provided at the center of the separated side of the outer walls of the two sleeve blocks 8.

[0029] Specifically, the device can be fixed to the outer wall of the mounting column through the hoop 4, and the distance between the two hoop rings 4 can be adjusted by the adjustment mechanism 11, so that when installing photovoltaic panels with larger mass, the stress on the hoop ring 4 caused by the load-bearing of the rotating arm 5 can be evenly shared by increasing the distance between the two hoop rings 4, so as to extend the service life of the hoop 4, and the rotating arm 5 can be rotated at the same time. At the same time, since the length of the support arm 10 is fixed, the support arm 10 drives the sleeve block 8 to slide on the surface of the rotating arm 5. When the rotating arm 5 is rotated to the appropriate position, the fixing mechanism 15 in the connecting block 7 can be used to fix the positions of the two sleeve blocks 8, thereby limiting the rotation of the support arm 10 and the rotating arm 5, and achieving the effect of supporting the rotating arm 5 through the support arm 10.

[0030] Reference Figure 1 、 Figure 2 The rotating shaft 1102 is rotatably set at the center of both sides of the inner wall of the adjusting box 2, the two longitudinal bevel gears 1103 are fixedly sleeved on both sides of the outer wall of the rotating shaft 1102, and the two transverse bevel gears 1101 are fixedly set on the upper end surfaces of the two double-headed screws 3.

[0031] Specifically, the rotating shaft 1102 drives the two transverse bevel gears 1101 to rotate respectively through the two longitudinal bevel gears 1103 on both sides of the outer wall thereof, thereby realizing the synchronous rotation of the two double-headed screws 3 .

[0032] Reference Figure 1 、 Figure 4 The two slides 1502 are slidably arranged inside the connecting block 7, the two embedded blocks 1501 are respectively fixedly arranged at the lower end of the center of the side away from the two slides 1502, and the two threaded rods 1503 are respectively rotatably arranged at the center of the upper end of the opposite side of the outer wall of the two sleeve blocks 8 and are rotatably connected to the fixed box 6.

[0033] Specifically, rotating the two threaded rods 1503 in opposite directions can drive the two slides 1502 to move closer or farther away, thereby achieving a fixing effect on the position of the insert 1501, so that the two inserts 1501 can fix the positions of the two sleeve blocks 8 respectively.

[0034] Reference Figure 1 、 Figure 2 The two double-headed screws 3 are respectively threaded through the centers of both sides of the upper end surfaces of the two hoop rings 4, and the two transverse bevel gears 1101 are respectively engaged with the two longitudinal bevel gears 1103.

[0035] Specifically, the two double-headed screws 3 can rotate synchronously with the two longitudinal bevel gears 1103 through the two transverse bevel gears 1101, so that the two double-headed screws 3 drive the two hoops 4 to move closer or farther away through rotation, thereby achieving the effect of adjusting the distance between the two hoops 4.

[0036] Reference Figure 1 、 Figure 3 、 Figure 4 A positioning hole 9 is formed through the front end of each side of the two rotating arms 5, and a through groove 12 is formed through the center of both sides of the outer wall of the two sleeve blocks 8. The two inserts 1501 are respectively slidably embedded in the two through grooves 12 and one of the multiple positioning holes 9 on the sleeve blocks 8 and the rotating arm 5 on the same side.

[0037] Specifically, the insert 1501 is embedded in the through slot 12 on the sleeve block 8 on the same side, and is also embedded in the positioning holes 9 arranged in the plurality of positioning holes 9 and located on the same horizontal line as the two through slots 12, thereby achieving the fixing effect of the sleeve block 8.

[0038] Reference Figure 4 The two threaded rods 1503 are respectively threaded through the two slides 1502 and rotate through the centers of both sides of the outer wall of the fixed box 6.

[0039] Specifically, it is convenient to fix the position of the threaded rod 1503 so that when the threaded rod 1503 is rotated, the two slides 1502 can move in opposite directions or towards each other.

[0040] Reference Figure 1 、 Figure 4 The two threaded rods 1503 are fixed with a second bevel gear 14 at one end relative to each other, and a first bevel gear 13 is rotatably provided at the center of the upper end surface of the inner wall of the fixed box 6 and is meshed with the two second bevel gears 14.

[0041] Specifically, by rotating the number one bevel gear 13 , the two number two bevel gears 14 can respectively drive the two threaded rods 1503 to rotate in opposite directions.

[0042] Working principle: During installation, the device is sleeved on the outer wall of the mounting column through two hoops 4, and the position of the device is fixed by the two hoops 4. When a photovoltaic panel with a larger mass needs to be installed, the rotating shaft 1102 can be rotated and the two transverse bevel gears 1101 and the two double-headed screws 3 can be driven to rotate synchronously through the two longitudinal bevel gears 1103, so that the distance between the two hoops 4 can be adjusted within a certain range, so that the stress on the hoop 4 caused by the gravity of the photovoltaic panel with a larger mass can be evenly distributed to the two hoops 4, thereby extending the service life of the hoop 4 to a certain extent;

[0043] When the installation is completed and the tilt angle of the photovoltaic panel needs to be adjusted, the No. 1 bevel gear 13 is rotated to drive the two threaded rods 1503 to rotate in opposite directions through the two No. 2 bevel gears 14 meshing therewith, so that the two slides 1502 respectively drive the two blocks 1501 to move to the opposite side, so that the two blocks 1501 are respectively disengaged from the two through grooves 12 on the same side sleeve 8 and the rotating arm 5 and the positioning holes 9 on the same horizontal line, thereby unlocking the position of the sleeve 8, and then rotating the rotating arm 5. Since the length of the support arm 10 is fixed, the support arm 10 pulls the sleeve 8 to slide on the outer wall of the rotating arm 5 while rotating during the rotation process. When the rotating arm 5 rotates to the appropriate position, the No. 1 bevel gear 13 is rotated in the opposite direction, so that the two blocks 1501 re-fix the positions of the two sleeves 8, thereby achieving the fixation of the angles of the support arm 10 and the rotating arm 5 to achieve the adjustment effect of the tilt angle of the photovoltaic panel.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
