The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0017] Example 1 like Figure 1-5As shown, this utility model provides an angle adjustment limiter, including a rotating column 1. A mounting circular plate 5 is rotatably connected to the surface of the rotating column 1 via a bearing. An annular anti-slip pad 11 is fixedly connected to the top surface of the mounting circular plate 5. A fixing baffle 12 is fixedly connected to the top surface of the mounting circular plate 5. A rotating ring 10 is provided at the upper end of the mounting circular plate 5. The rotating ring 10 is rotatably sleeved on the surface of the rotating column 1 via a bearing. A rotating baffle 8 is fixedly connected to the side of the rotating ring 10. A positioning component 9 is provided at the top of the rotating baffle 8. A second mounting through hole 13 is opened on the side of both the rotating baffle 8 and the fixing baffle 12. A buffer component 7 is provided inside the second mounting through hole 13. A mounting ring 4 is fixedly sleeved on the side of the mounting circular plate 5. A curved baffle 3 is fixedly connected to the side of the rotating column 1. Mounting discs 2 are fixedly connected to both the upper and lower end faces of the rotating column 1. An angle line 6 is opened on the top surface of the mounting circular plate 5.
[0018] Specifically, in use, the mounting plate 2 at the top of the rotating column 1 aligns with the rotating rod, and the mounting plate 2 at the bottom of the rotating column 1 aligns with the output shaft of the drive device. The mounting ring 4 on the side of the mounting plate 5 is fixedly installed to the equipment housing, and then it can be used. During use, the rotating ring 10 allows the rotating baffle 8 to rotate. The angle of rotation of the rotating baffle 8 can be controlled by the angle line 6. After adjusting to a suitable angle, the rotating baffle 8 is limited in position by the positioning component 9 and the annular anti-slip pad 11. When the rotating column 1 rotates, it drives the bending baffle 3 to rotate. The bending baffle 3 is limited in position by the rotating baffle 8 and the fixed baffle 12, thus limiting the rotation angle of the rotating column 1. The buffer component 7 acts as a buffer, preventing the bending baffle 3 from being damaged by excessive impact when it directly contacts the fixed block and the rotating baffle 8.
[0019] In this embodiment, the positioning component 9 includes a mounting through hole 94 opened on the top of the rotating baffle 8. A trapezoidal nut 93 is fixedly connected inside the mounting through hole 94. A trapezoidal screw 92 is threaded inside the trapezoidal nut 93. A rotating cap 91 is fixedly connected to the top surface of the trapezoidal screw 92. The bottom of the trapezoidal screw 92 abuts against the top surface of the annular anti-slip pad 11.
[0020] Specifically, the trapezoidal screw 92 can be rotated upwards or downwards by rotating the cap 91 under the action of the trapezoidal nut 93. When rotating upwards, the limit on the rotating baffle 8 is released, and the rotating baffle 8 can be rotated under the action of the rotating ring 10; while when rotating downwards, the trapezoidal screw 92 can abut against the annular anti-slip pad 11, so that the rotating baffle 8 is used for limit.
[0021] In this embodiment, the buffer assembly 7 includes a slide cylinder 73 that is fixedly connected to the interior of the mounting through hole 13. A compression plate 74 is slidably connected to the inner wall of the slide cylinder 73. A spring 75 is fixedly connected to one side of the compression plate 74, and a slide rod 72 is fixedly connected to the other side of the compression plate 74. The slide rod 72 passes through one end of the slide cylinder 73 and is slidably connected to the through portion. A rubber block 71 is fixedly connected to one end face of the slide rod 72. Mounting holes that are evenly distributed in a circular pattern are opened on the surfaces of the mounting plate 2 and the mounting ring 4.
[0022] Specifically, the rubber block 71 can initially buffer the impact force of the bending baffle 3. When the rubber block 71 is subjected to the impact force, the slide rod 72 will drive the compression plate 74 to slide inside the slide cylinder 73, causing the spring 75 to be compressed, thereby buffering the impact force again.
[0023] The specific working principle and usage method of this utility model are as follows: This utility model provides an angle adjustment limiter, such as Figure 1-5 As shown, in use, the top mounting plate 2 is connected and fixed to the rotating rod to be limited through the mounting holes on the surfaces of the mounting plates 2 at both ends of the rotating column 1, and the bottom mounting plate 2 is connected and fixed to the output shaft of the drive equipment. Then, the mounting ring 4 is fixed to the equipment housing through the mounting holes on the side of the mounting plate 5, ensuring that the mounting plate 5 and the fixed baffle 12 are stable and do not move. Next, adjust the angle of the rotating baffle 8 according to the limiting requirements. By holding the rotating cap 91 and rotating it clockwise, the trapezoidal screw 92 is driven to rotate upward along the trapezoidal nut 93, so that the bottom of the trapezoidal screw 92 is disengaged from the annular anti-slip pad 11, thus releasing the limiting effect on the rotating baffle 8. Then, hold the rotating baffle 8 and rotate it around the rotating column 1 via the rotating ring 10. Observe the rotation angle by combining it with the angle line 6 on the top surface of the mounting circular plate 5. When the included angle between the rotating baffle 8 and the fixed baffle 12 reaches the preset limiting angle, rotate the rotating cap 91 counterclockwise, so that the trapezoidal screw 92 rotates downward and tightly abuts against the annular anti-slip pad 11. Utilize the self-locking property of the trapezoidal screw 92 and the trapezoidal nut 93 and the friction of the annular anti-slip pad 11 to stably limit the rotation of the baffle 8. When the device is put into use, the drive unit rotates the rotating column 1, which in turn rotates the side bending baffle 3 synchronously. When the bending baffle 3 rotates to contact the buffer assembly 7 on the side of the fixed baffle 12 or the rotating baffle 8, the rubber block 71 first collides with the bending baffle 3, providing initial cushioning. The impact force pushes the rubber block 71, causing the slide rod 72 to slide into the slide cylinder 73. The slide rod 72 pushes the compression plate 74 to compress the spring 75. The elasticity of the spring 75 further cushions the impact force, preventing damage to components from hard collisions. At the same time, the bending baffle 3 is blocked, and the rotating column 1 stops rotating, achieving angle limiting. If the limiting angle needs to be adjusted, repeat the above operation of rotating cap 91 to release the limit, adjust the angle of the rotating baffle 8, and then relock.

However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
