[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1: like Figures 1-8 As shown, a high-speed rolling shutter door post with grooves includes a post body; One side of the column body is provided with a mating groove 1 for the curtain assembly to extend into, and the side of the column body facing away from the curtain assembly is provided with a vertically extending groove 2, the cross-section of which is U-shaped. The U-shaped opening end of the wire groove 2 is provided with a cover plate 3, and a wire routing channel 4 extending in the vertical direction is formed between the wire groove 2 and the cover plate 3. The cover plate 3 and the groove 2 are connected by a snap-fit ​​connection.

[0031] Preferably, the two parallel sidewalls of the wire groove 2 are symmetrically provided with slots 21, and the end of the cover plate 3 facing the wire groove 2 is provided with a cover plate buckle that is snapped into the slots 21.

[0032] Preferably, the cover plate buckle includes two symmetrically arranged buckle blocks 31, and a buckle protrusion 32 is provided at the end of the two buckle blocks 31 on opposite sides away from the cover plate 3; The slot 21 has end stops 211 on both sides facing each other to prevent the cover plate buckle from coming out of the slot 21.

[0033] Preferably, two positioning blocks 34 are vertically arranged at one end of the cover plate 3 facing the wire groove 2; During the process of the cover plate buckle being inserted into the slot 21, when the end face of the positioning block 34 away from the cover plate 3 abuts against the corresponding end stop 211, the cover plate 3 is installed in place.

[0034] In this application, the installation depth of the cover plate 3 in the slot 21 is limited by the setting of the positioning block 34, which ensures the consistency of the assembly position of the cover plate 3.

[0035] Preferably, the two positioning blocks 34 are located outside the two cover plate buckles, and the two ends of the cover plate 3 are vertically bent to form the positioning blocks 34.

[0036] Preferably, in its natural state, the cover plate buckle forms a gradually expanding slope groove 33 between the two buckle blocks 31. The width of the gradually expanding slope groove 33 is smaller as it gets closer to the cover plate 3, so that the two buckle blocks 31 of the cover plate buckle form an outward-opening structure. After the cover plate buckle is inserted into the buckle groove 21 and naturally unfolds, it will automatically lock due to its outward-opening structure and will not loosen.

[0037] Preferably, in the cover plate buckle, the ends of the two opposite sides of the buckle protrusions 32 that are away from the cover plate 3 are provided with chamfers 321 to facilitate the cover plate buckle entering the buckle groove 21.

[0038] In Embodiment 1, a wire groove 2 is provided on the side of the column body facing away from the door curtain assembly. A cover plate 3 is snapped to the groove opening of the wire groove 2, forming a wiring channel 4 between the cover plate 3 and the wire groove 2 for the corresponding cables to run. The cover plate 3 seals the wire groove 2, thereby preventing the cables from being exposed and improving the appearance of the high-speed rolling shutter door. At the same time, the cover plate 3 is snapped to the wire groove 2, making it easy to install and remove.

[0039] Example 2: Based on Embodiment 1, the cross-section of the mating groove 1 is U-shaped, and dustproof mechanisms 5 are symmetrically arranged on the two parallel sidewalls of the mating groove 1.

[0040] Preferably, the inner side of the groove of the mating groove 1 is symmetrically provided with connecting parts 11, and the two connecting parts 11 are symmetrically provided with dustproof slots 111 extending through in the vertical direction on the opposite side; The dustproof mechanism 5 includes a dustproof insertion part 51 for vertically inserting into the dustproof slot 111, and a plurality of brushes 52 are arranged on one side of the dustproof insertion part 51 in the vertical direction. The brushes 52 on the two dustproof connectors 51 extend out of the corresponding dustproof slots 111 and are positioned facing each other.

[0041] Specifically, the dustproof slot 111 has a rectangular cross-section and a through connection 11 for the brush 52 to extend outwards.

[0042] Preferably, in each dustproof mechanism 5, when the brushes 52 are in their natural state, the central axes of all the brushes 52 form a vertical plane 6, and the two vertical planes 6 in the two dustproof mechanisms 5 intersect to form a V-shaped structure, with the intersection line of the two vertical planes 6 far from the groove opening of the mating groove 1. This arrangement can reduce the friction between the curtain assembly and the brushes 52 during the up-and-down movement of the curtain assembly.

[0043] During the use of the high-speed rolling shutter door, dust can enter the mating groove 1, and over time, this accumulation can affect the up-and-down movement performance of the door curtain assembly. In Embodiment 2, the dustproof mechanism 5 filters the dust, reducing the likelihood of dust entering the inner side of the mating groove 1.

[0044] Example 3: Based on Embodiment 1 or Embodiment 2, a limiting buffer part 7 is symmetrically provided on one side of the two connecting parts 11 facing each other. The limiting buffer part 7 is located between the groove opening of the mating groove 1 and the dustproof mechanism 5. The connecting part 11 is provided with a limiting slot 112 that extends through in the vertical direction; The limiting buffer part 7 includes a limiting plug part 72 that is vertically plugged into the limiting slot 112. A limiting post 71 extending vertically is fixedly provided on one side of the two limiting plug parts 72 facing each other. The limiting post 71 has a hollow structure. Specifically, the cross-section of the limiting slot 112 is arc-shaped.

[0045] The limiting buffer part 7 is made of rubber, specifically, it is made of EPDM rubber.

[0046] The width L1 of the vertical guide space formed between the two limiting posts 71 is greater than the maximum thickness L2 of the curtain assembly, thus providing space for the curtain assembly to move up and down and preventing jamming. At the same time, the limiting posts 71 limit the swaying of the curtain assembly.

[0047] In embodiment 3, a vertical guide space is formed between the two limiting buffer parts 7 in the mating groove 1 for the curtain assembly to move up and down. The two limiting posts 71 limit the swaying of the curtain assembly during the up and down movement. The limiting buffer parts 7 also prevent the curtain assembly from hitting the groove opening of the mating groove 1 during the up and down movement and causing wear.

[0048] Example 4: A type of high-speed rolling shutter door, such as Figures 9-10 As shown, the curtain assembly includes a curtain assembly comprising several curtains 01 arranged vertically, adjacent curtains 01 being connected by ribs 02, and a bottom support beam 03 being fixedly installed at the bottom end of the lowest curtain 01 in the curtain assembly. The upper end of the curtain assembly is fixed on the roller 04, and the two ends of the roller 04 are rotatably fitted on the corresponding brackets 06. One end of the roller 04 is equipped with a motor 05; wherein the motor 05 is fixedly mounted on a column on one side. Each bracket 06 is fixedly mounted on a row of high-speed rolling shutter door columns with grooves, as shown in Embodiment 1, Embodiment 2, or Embodiment 3. The mating grooves 1 of the two column bodies are arranged facing each other, and the two ends of the unrolled part of the curtain assembly extend into the mating grooves 1, wherein the brush 52 presses against the curtain assembly.

[0049] In Example 4, motor 05 drives roller 04 to rotate, rolling up the curtain assembly to open the door; motor 05 drives roller 04 to rotate in the opposite direction, and the curtain assembly releases under its own weight, closing the door. During the up-and-down movement of the curtain assembly along the vertical guide channel between the two limiting posts 71, the two limiting posts 71 limit its swaying.

[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
