[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 7 The present invention provides a synchronous pulley fixed installation shaft side seat, comprising a side seat frame 1 and a synchronous pulley 2, the synchronous pulley 2 is provided with an output shaft 4 on its surface, the side seat frame 1 is provided with a placement groove for placing the output shaft 4 on its surface, an arc-shaped limit plate 1 3 is fixedly installed on the inner wall of the placement groove, a plurality of rolling columns 1 are connected to the arc-shaped limit plate 1 3 for fixed axis rotation, and an arc-shaped limit plate 2 9 is provided above the arc-shaped limit plate 3 13; The fixed shaft side seat also includes: The limiting component, the locking component and the auxiliary component are arranged in the side seat frame 1.

[0020] The limiting component includes two fixed blocks 23 fixedly mounted on the upper surface of the arc-shaped limiting plate 3 13, the surface of the fixed block 23 is connected to a rotating rod 1 25 in a fixed axis rotation, the surface of the rotating rod 1 25 is fixedly connected to a connecting block 1 24, the arc-shaped limiting plate 2 9 is fixedly connected to the connecting block 1 24, and the arc-shaped limiting plate 2 9 is connected to a plurality of rolling columns 2 10 in a fixed axis rotation; A rectangular slot 1 is provided on the inner wall of the side seat frame 1, a moving block 15 is slidably connected to the inner wall of the rectangular slot 1, a threaded rod 16 is also rotatably connected to the inner wall of the rectangular slot 1, the threaded rod 16 penetrates the moving block 15 and is threadedly connected thereto, two hinge blocks 18 are symmetrically provided on the surface of the moving block 15, and the moving block 15 is hinged to two symmetrically provided hinge plates 19 through the two hinge blocks 18.

[0021] A rectangular slot 2 is provided on the inner wall of the side seat frame 1, a slider 1 41 is slidably connected to the inner wall of the rectangular slot 2, the end of the slider 1 41 extending out of the rectangular slot 2 is fixedly connected to a rack row 28, a connecting rod 1 27 is fixedly connected to the lower surface of the rack row 28, an arc-shaped limit plate 3 13 is fixedly installed on the end of the connecting rod 1 27, a connecting block 21 is fixedly connected to the surface of the arc-shaped limit plate 3 13, a hinge block 20 is fixedly connected to the lower surface of the connecting block 21, and an end of the hinge plate 19 is hinged to the hinge block 20; The surface of the placement groove is fixedly connected to a support block, the surface of the support block is fixedly connected to a rotating shaft 30, the surface of the rotating shaft 30 is fixedly connected to a gear 29 meshing with the rack row 28, and the surface of the rotating rod 25 is fixedly connected to a gear 26 meshing with the gear 29.

[0022] The surface of the side seat frame 1 is rotatably connected to a rotating rod 2 7 , one end of which is fixedly connected to a rotating shaft 22 , a bevel gear transmission mechanism 17 is provided between the rotating shaft 22 and the threaded rod 16 , and a turntable 8 is provided at the other end of the rotating rod 27 .

[0023] In this embodiment, Figure 1 and Figure 2 As shown, the synchronous pulley 2 is placed in the side seat frame 1, and the output shafts 4 at both ends thereof are placed in the placement grooves of the side seat frame 1.

[0024] like Figure 4 As shown, rotating the turntable 8 drives the rotating rod 2 7 and the rotating shaft 22 to rotate synchronously. With the rotation of the rotating shaft 22, the threaded rod 16 will rotate synchronously under the transmission action of the bevel gear transmission mechanism 17. With the rotation of the threaded rod 16, the moving block 15 will start to descend.

[0025] like Figure 3 As shown, since the two arc-shaped limit plates 3 13 are limited and can only move in the horizontal direction, as the moving block 15 descends, the two arc-shaped limit plates 3 13 will be driven to move towards the direction close to the output shaft 4 under the hinged action of the two hinged plates 19.

[0026] like Figure 5As shown, with the movement of the arc-shaped limit plate 3 13 on the left side toward the output shaft 4, the connecting rod 1 27 and the rack row 28 will be driven to move synchronously, and under the meshing action of the gear 1 29 and the rack row 28, with the movement of the rack row 28, the gear 1 29 will start to rotate, and under the meshing action of the gear 1 29 and the gear 2 26, the gear 2 26 will drive the rotating rod 1 25 to rotate, and with the rotation of the rotating rod 1 25, the arc-shaped limit plate 29 and the connecting block 1 24 will rotate 90 degrees in a circle with the axis of the rotating rod 1 25 as the axis. When the arc-shaped limit plate 29 completes the rotation of 90 degrees, it will rotate to the top of the output shaft 4, and the multiple rolling columns 1 on its surface that are fixedly rotatably connected will also be in a position abutting against the output shaft 4, that is, the arc-shaped limit plate 29 will be placed on the output shaft 4 at this time.

[0027] It is worth noting that when the arc-shaped limit plate 29 rotates 90 degrees and rests on the output shaft 4, the two arc-shaped limit plates 3 13 will not move to the position abutting the output shaft 4, that is, the output shaft 4 will only be affected by the gravity of the arc-shaped limit plate 29. In this state, the output shaft 4 on one side of the synchronous pulley 2 can be pushed to move the synchronous pulley 2 to the other side inside the side seat frame 1, thereby changing the position of the synchronous pulley 2 inside the side seat frame 1, so that multiple sets of synchronous pulleys 2 can be adjusted and aligned according to the use needs in the intelligent assembly line of photovoltaic modules.

[0028] It is worth noting that while debugging the position of the synchronous pulley 2 in the side seat frame 1, the arc-shaped limit plate 9 resting on the output shaft 4 can limit the moving output shaft 4, thereby preventing the output shaft 4 from slipping out of the placement groove due to excessive thrust, thereby being able to more stably adjust the position of the synchronous pulley 2 in the side seat frame 1.

[0029] Embodiment 2, based on the above embodiment: Furthermore, the locking component includes a plurality of rolling columns 14 rotatably connected to the arc-shaped limit plate 13 via a fixed axis, a mounting plate 38 is fixedly connected to the surface of the placement groove, a limit frame 37 is fixedly installed on the end of the mounting plate 38, an abutment block 39 is slidably connected to the inner wall of the limit frame 37, a connecting rod 36 is fixedly connected to the surface of the abutment block 39, an end of the connecting rod 36 is fixedly connected to the hinge block 20, and a sliding groove 35 is provided on the surface of the limit frame 37 for the connecting rod 36 to extend and slide.

[0030] The auxiliary components include a locking frame 31 fixedly mounted on the upper surface of the arc-shaped limit plate 1 3, an insert block 11 is fixedly mounted on the end of the arc-shaped limit plate 2 9 away from the arc-shaped limit plate 3, a circular notch 12 is provided on the surface of the insert block 11, an insert rod 32 is slidably connected to the surface of the locking frame 31, an end of the insert rod 32 is fixedly connected to a hinge block 3 33, and a hinge plate 2 34 is hingedly connected to the surface of the hinge block 33.

[0031] The inner wall of the limiting frame 37 is slidably connected with a second slider 40 , the end of the second hinge plate 34 is hinged to the second slider 40 , and a spring 42 is provided between the second slider 40 and the inner wall of the limiting frame 37 .

[0032] In this embodiment, after the position debugging of the synchronous pulley 2 in the side seat frame 1 is completed, the turntable 8 is rotated again to drive the two arc-shaped limit plates 3 13 to move again in the direction close to the output shaft 4 until the two arc-shaped limit plates 3 13 abut against the output shaft 4. At this time, under the abutment of the two arc-shaped limit plates 3 13, the output shaft 4 can be locked in the axial direction, that is, the synchronous pulley 2 can be locked in the side seat frame 1, thereby ensuring the stability of the subsequent synchronous pulley 2 during transmission work.

[0033] It is worth noting that Figure 6 and Figure 7 As shown, when the turntable 8 is rotated for the first time and the arc limit plate 3 13 is driven to move toward the output shaft 4, under the connection action of the hinge block 20 and the connecting rod 2 36, the movement of the arc limit plate 3 13 will also drive the abutment block 39 to move in the limit frame 37. As the arc limit plate 3 13 moves, when the arc limit plate 2 9 is rotated to a position resting on the output shaft 4, the insert block 11 at its end will also rotate into the locking frame 31. At this time, the abutment block 39 will move to a position abutting against the slider 2 40 and will not push the slider 2 40 to move. After the position debugging of the synchronous pulley 2 in the side seat frame 1 is completed, the turntable 8 is rotated again. As the arc limit plate 3 13 continues to move, the abutment block 39 will push the slider 2 40 to move synchronously.

[0034] As the slider 40 moves, the hinged action of the hinged plate 34 will cause the insertion rod 32 to move toward the inside of the locking frame 31. Since the insertion block 11 at the end of the arc-shaped limit plate 29 has entered the locking frame 31 at this time, as the insertion rod 32 moves, the insertion rod 32 will be inserted into the circular groove 12 on the surface of the insertion block 11. Under the cooperation of the insertion rod 32 and the insertion block 11, the arc-shaped limit plate 29 can be fixed above the output shaft 4, so that the synchronous pulley 2 and the output shaft 4 can be re-positioned after the debugging is completed.

[0035] Since the surfaces of the arc limit plate 1 3, the arc limit plate 2 9 and the arc limit plate 3 13 are respectively connected to the rolling column 1, the rolling column 2 10 and the rolling column 3 14 in a fixed-axis rotation manner, the arc limit plate 1 3, the arc limit plate 2 9 and the arc limit plate 3 13 will only limit the synchronous pulley 2 and the output shaft 4 from moving in the side seat frame 1, but when the synchronous pulley 2 is performing transmission work, it will not affect the rotation of the output shaft 4, and under the limiting action of the arc limit plate 1 3, the arc limit plate 2 9 and the arc limit plate 3 13, the jitter of the output shaft 4 during rotation can be reduced, thereby improving the stability of the synchronous pulley 2 during transmission use, and is worthy of promotion and use.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
