[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0027] Example 1:

[0028] An automatic clutch for a roller shutter door opening and closing machine includes a mounting frame 1, a drive motor 2 and an automatic clutch 3. The automatic clutch 3 is fixedly installed at the output end of the drive motor 2, the drive motor 2 is fixedly installed on the top of the mounting frame 1, an air pipe 4 is fixedly connected to one side of the automatic clutch 3, a support rod 5 is fixedly connected to the top of the mounting frame 1, a support plate 6 is provided on the top of the support rod 5, and a support mechanism is provided on the top of the support plate 6.

[0029] The support mechanism includes a T-shaped groove 7 opened on the top of the support plate 6. Two T-shaped sliders 8 are slidably connected inside the T-shaped groove 7. A sleeve 9 is fixedly connected to the top of the T-shaped sliders 8. A telescopic block 10 is inserted into the sleeve 9. A positioning frame 11 is fixedly connected to the top of the telescopic block 10. A screwing block 12 is provided on the top of the positioning frame 11. A threaded rod 13 is fixedly connected to the bottom of the screwing block 12. A bearing 14 is provided at the bottom of the threaded rod 13, and a pressure plate 15 is rotatably connected through the bearing 14. A threaded hole 27 is opened on the top of the positioning frame 11 to cooperate with the threaded rod 13. An adjustment mechanism is provided on one side of the sleeve 9.

[0030] In this embodiment, considering that vibrations occur during the operation of the roller shutter door opening and closing mechanism, and that the air pipe 4 used for charging gas often lacks a supporting function and will swing with the movement, leading to easy damage to the air pipe 4 and thus affecting the normal operation of the automatic clutch 3, a support mechanism is provided to ensure that after the air pipe 4 is connected to the automatic clutch 3, the air pipe 4 can be supported. Figure 1 , Figure 3 and Figure 4 Place the air tube 4 in the positioning frame 11, then rotate the screwing block 12 to drive the threaded rod 13 to rotate inside the threaded hole 27. The threaded rod 13 gradually moves downward, while driving the bearing 14 and the pressure plate 15 to move downward along the trajectory of the sliding block 21 and the sliding groove 22 until the pressure plate 15 contacts the air tube 4, limiting the position of the air tube 4. This completes the support and limitation of the air tube 4, preventing the air tube 4 from shaking and extending its service life.

[0031] This solves the problem that the air pipe 4 used for filling gas often lacks a supporting function and will swing during the operation of the roller shutter door opening and closing machine, which is prone to damage.

[0032] Two sliding blocks 21 are fixedly connected to one side of the pressure plate 15, and a sliding groove 22 that cooperates with the sliding blocks 21 is provided on one side of the positioning frame 11.

[0033] In this embodiment, by setting the sliding block 21 and the sliding groove 22, when the threaded rod 13 rotates and drives the pressure plate 15 to move downward, the movement trajectory of the pressure plate 15 is restricted, so that it can only move downward along the trajectory of the sliding block 21 and the sliding groove 22, thereby limiting the movement trajectory.

[0034] The pressure plate 15 is arc-shaped and has an anti-slip pad 23 fixedly connected to its bottom.

[0035] In this embodiment, by setting an anti-slip pad 23, the friction of the contact between the pressure plate 15 and the air pipe 4 can be increased, thereby achieving the anti-slip effect.

[0036] A spring 24 is fixedly connected to the bottom of the telescopic block 10, and the bottom of the spring 24 is fixedly connected to the inner wall of the sleeve 9.

[0037] In this embodiment, by setting a spring 24, when the airway 4 vibrates, the reaction force generated by the spring 24 can achieve a buffering effect, further protecting the airway 4.

[0038] A guide rod 25 is fixedly connected to the inner wall of the sleeve 9, and a guide hole 26 is provided at the bottom of the telescopic block 10 to cooperate with the guide rod 25.

[0039] In this embodiment, by setting guide rod 25 and guide hole 26, when air tube 4 vibrates, the telescopic block 10 can only move downward to compress spring 24, thereby limiting the movement trajectory.

[0040] Example 2:

[0041] Based on Embodiment 1, the support mechanism in this embodiment can support and restrict the airway 4 to prevent the airway 4 from swinging and being damaged. However, considering that the length of the airway 4 is different, if the support position cannot be reasonably adjusted according to the length of the airway 4, the support effect will also be affected. In this application, the adjustment mechanism includes a support frame 16 fixedly connected to one side of the sleeve 9. A pulling block 17 is provided on one side of the support frame 16. A pin 18 is fixedly connected to one side of the pulling block 17. One end of the pin 18 passes through to one side of the support frame 16. A pin hole 19 is opened on one side of the support plate 6 to cooperate with the pin 18. A tension spring 20 is fixedly connected to one side of the pulling block 17. One end of the tension spring 20 is fixedly connected to one side of the support frame 16.

[0042] In this embodiment, considering the varying lengths of the trachea 4, if the support position cannot be adjusted appropriately according to the length of the trachea 4, the support effect will be affected. Therefore, by setting an adjustment mechanism, the pull block 17 can be moved forward, as referenced. Figure 2 , Figure 3 and Figure 4Pulling block 17 will drive pin 18 forward, causing pin 18 to leave the inside of pin hole 19, thus releasing the restriction on the position of support frame 16 and sleeve 9. Then, the position of support frame 16 and sleeve 9 can be adjusted along the trajectory of T-shaped slider 8 and T-shaped groove 7. After reaching the appropriate position, pull block 17 is released, and the tension generated by tension spring 20 will drive pin 18 into the corresponding pin hole 19, completing the adjustment of the position of support frame 16 and sleeve 9, thereby achieving the adjustment of the support position of the support mechanism.

[0043] The number of pin holes 19 is several, and they are evenly distributed on one side of the support plate 6.

[0044] In this embodiment, by setting a number of pin holes 19, after the positions of the support frame 16 and the sleeve 9 are adjusted, the pin rod 18 can be inserted into the corresponding pin hole 19 to complete the quick fixation.

[0045] Working principle: After the air pipe 4 is connected to the automatic clutch 3, refer to... Figure 1 , Figure 3 and Figure 4 Place the air tube 4 in the positioning frame 11, then rotate the screwing block 12 to drive the threaded rod 13 to rotate inside the threaded hole 27. The threaded rod 13 gradually moves downward, while driving the bearing 14 and the pressure plate 15 to move downward along the trajectory of the sliding block 21 and the sliding groove 22 until the pressure plate 15 contacts the air tube 4, limiting the position of the air tube 4. This completes the support and limitation of the air tube 4, preventing the air tube 4 from shaking and extending its service life.

[0046] Alternatively, you can move block 17 forward, see reference. Figure 2 , Figure 3 and Figure 4 Pulling block 17 will drive pin 18 forward, causing pin 18 to leave the inside of pin hole 19, thus releasing the restriction on the position of support frame 16 and sleeve 9. Then, the position of support frame 16 and sleeve 9 can be adjusted along the trajectory of T-shaped slider 8 and T-shaped groove 7. After reaching the appropriate position, pull block 17 is released, and the tension generated by tension spring 20 will drive pin 18 into the corresponding pin hole 19, completing the adjustment of the position of support frame 16 and sleeve 9, thereby achieving the adjustment of the support position of the support mechanism.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
