[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0030] like Figure 1 As shown, an electric cage rolling door, wherein:

[0031] The tank cage 10 includes a plurality of curtain posts 11 provided on the front side wall of the tank cage 10;

[0032] The anti-stuck device can prevent the multiple curtain posts 11 from getting stuck. The anti-stuck device includes multiple blocking rods 15. The multiple blocking rods 15 are respectively arranged at the upper positions of the front and rear sides of the multiple curtain posts 11.

[0033] The protective device can protect the uppermost and lowermost curtain posts 11. The protective device includes two soft pads 13. The two soft pads 13 are respectively arranged at one end of the uppermost and lowermost curtain posts 11 away from each other.

[0034] It is worth noting that the cage 10 and the curtain column 11 have been disclosed in an electric cage rolling shutter door (202320703543.4), and are not described in detail here.

[0035] Shock absorbers are used to dampen the rebound oscillations caused by springs absorbing shock and to reduce road impact. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations, improving ride comfort. While shock-absorbing springs can filter out road vibrations when driving over uneven surfaces, the springs themselves still experience reciprocating motion, and shock absorbers are designed to dampen this spring bounce. Shock absorbers 19 are state-of-the-art and will not be described in detail here.

[0036] During specific use, the anti-stuck device can effectively prevent foreign objects from being inserted between the multiple curtain posts 11 through the multiple blocking rods 15, resulting in the inability to retract. The protective device can reduce the vibration of the top and bottom curtain posts 11 when they move, and can effectively protect the top and bottom curtain posts 11 and increase their service life.

[0037] In summary, by providing the anti-jamming device and the protective device, the anti-jamming device can prevent foreign objects from being inserted between the multiple curtain posts 11, causing them to become unable to operate. The protective device can protect the topmost and bottommost curtain posts 11, effectively reducing their vibration and thus increasing their service life. Compared with the prior art, the present invention is easy to use and has a simple structure.

[0038] like Figure 2 、 Figure 3 and Figure 5 As shown, two fixing blocks 16 are fixedly installed on the front side walls of the plurality of curtain posts 11 , and the bottom walls of the plurality of blocking rods 15 are fixedly connected to the corresponding two fixing blocks 16 .

[0039] A through slot 17 is provided on the top wall of each of the plurality of baffles 15 at a position corresponding to the position of the fixing block 16 , and the upper fixing block 16 can be inserted into the cavity of the lower fixing block 16 . No fixing block 16 is fixedly installed on the front side wall of the lowest curtain column 11 .

[0040] A first limiting hole 22 is provided on both left and right ends of the front wall of the cage 10 , and a second limiting hole 23 is provided on both left and right side walls of the cavity of the cage 10 .

[0041] An L-shaped block 14 is fixedly installed at the rear positions of the left and right sides of the plurality of curtain posts 11 , and the L-shaped block 14 is movably connected to the first limiting hole 22 and the second limiting hole 23 .

[0042] In actual use, when the multiple curtain posts 11 are deployed, the barrier rod 15 located above the multiple curtain posts 11 can provide a certain degree of blocking effect above the curtain posts 11, preventing foreign objects from getting stuck between the multiple curtain posts 11 and causing them to become unable to operate. The fixing block 16 can also serve as a limiter for the barrier rod 15, and the through groove 17 can cooperate with the operation of the fixing block 16. When two curtain posts 11 are close to each other, the fixing block 16 is accommodated in the cavity of the through groove 17. The L-shaped block 14 can limit the curtain posts 11 through the first limiting hole 22 and the second limiting hole 23.

[0043] In summary, by providing the L-shaped block 14, the stopper 15, the fixing block 16, the through slot 17, the curtain post 11, the cage 10, the first limiting hole 22, and the second limiting hole 23, the curtain post 11 can be limited by the connection between the L-shaped block 14 and the first limiting hole 22 and the second limiting hole 23. The multiple stopper bars 15 can block the upper part of the curtain post 11, effectively preventing foreign objects from being inserted between the multiple curtain posts 11 and affecting the operation.

[0044] like Figure 4 As shown, a shock absorbing plate 21 is fixedly mounted on the side wall of the uppermost and lowermost curtain posts 11 away from each other, and a shock absorber 19 is fixedly mounted on both left and right ends of the side wall of the two shock absorbing plates 21 away from each other.

[0045] A through hole 18 is provided on the wall surface of each of the two cushions 13 that are close to each other, and one end of each of the two corresponding shock absorbers 19 away from the corresponding shock absorbing plate 21 is fixedly connected to the wall surface of the two cushions 13 that are away from each other.

[0046] During actual use, when the lower curtain post 11 is descending, a certain impact force is generated. The soft pad 13 can buffer the impact force generated, and the shock absorber 19 can also play a certain shock-absorbing role. When multiple curtain posts 11 move upward, they will also vibrate due to the movement of multiple curtain posts 11. The shock absorber 19 and the soft pad 13 can eliminate the impact force, thereby improving the service life of the uppermost and lowermost curtain posts 11.

[0047] In summary, by providing the curtain post 11, the cushion 13, the perforation 18, the shock absorber 19 and the shock absorbing plate 21, the cushion 13 and the shock absorber 19 can eliminate the vibration and impact force generated by the movement of the curtain post 11, thereby improving the service life of the uppermost and lowermost curtain posts 11. The curtain post 11 is easy to use and has a simple structure.
