Description

Technical Field

[0001] The present application relates to the field of rolling door equipment, and in particular to a rolling door with a protective function. Background Art

[0002] Rolling shutter door is a door that is connected in series with multiple joints and rotates up and down on a fixed slide with the scroll above the door as the center. It is widely used in shops, home garages, warehouses and other places due to its easy installation, convenient opening and closing, and low cost.

[0003] In the prior art, the structure of rolling shutter doors is simple, and thin iron sheets are usually used as door panels. In the event of a theft in a store, thieves can easily damage the rolling shutter doors, thereby stealing the money in the store and causing losses. During the manufacturing process of the rolling shutter doors, harder metals are usually added to increase the hardness. Even so, they cannot be avoided from being damaged, and the anti-theft effect is poor, posing a safety hazard. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a rolling shutter door with a protective function.

[0005] The present application provides a rolling shutter door with protective function adopts the following technical solution:

[0006] A rolling shutter door with a protective function comprises a protective box, a reel arranged in the protective box, a guide rail arranged below the protective box and a protective net arranged on the reel, the protective net comprises a plurality of net chains, the net chains are hingedly connected via hinge shafts, the upper and lower ends of the plurality of hinge shafts form a plug-in fixing structure with curtain plates via the net chains, and a plurality of curtain plates are arranged parallel to the reel.

[0007] A further technical solution is that the curtain plate comprises a front panel and a rear panel, and the front panel is connected to the rear panel by bolts.

[0008] A further technical solution is that the opposite end surfaces of the front panel and the rear panel are provided with embedding grooves for embedding the network chain, and the front panel and the rear panel are slidably arranged in the guide rail.

[0009] This application has the following beneficial technical effects:

[0010] By setting up multiple hinged protective nets to increase the protection layer of the rolling door, the nets can be rolled up on the reel. When the curtain plate is damaged, the protective nets can still be used to prevent outsiders from entering. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0016] The present application embodiment discloses a rolling door with a protective function. Figure 1 and Figure 2 A rolling shutter door with a protective function includes a protective box 1, a reel 2 arranged in the protective box 1, a guide rail 3 arranged below the protective box 1 and a protective net 4 arranged on the reel 2, wherein the protective net 4 includes a plurality of net chains 41, and the net chains 41 are hingedly connected through a hinge shaft 42. The upper and lower ends of the plurality of hinge shafts 42 form a plug-in fixing structure with a curtain plate 5 through the net chains 41, and a plurality of curtain plates 5 are arranged parallel to the reel 2.

[0017] The curtain plate 5 and the hinge shaft 42 are both slidably arranged in the guide rail 3, and a motor 21 is arranged at the end of the reel 2 to drive the reel 2 to drive the protective net 4 to rise or fall. The protective net 4 is a metal chain net, which is used to increase the protective layer of the rolling door. When the curtain plate 5 is damaged, the protective net 4 can still be used to prevent outsiders from entering.

[0018] Furthermore, the curtain plate 5 includes a front panel 51 and a rear panel 52, and the front panel 51 is bolted to the rear panel 52. The opposite end surfaces of the front panel 51 and the rear panel 52 are provided with an embedding groove 53 for embedding the network chain 41, and the two ends of the front panel 51 and the rear panel 52 are slidably arranged in the guide rail 3.

[0019] Reference Figure 3 The mesh chain 41 and the embedding groove 53 are both diamond-shaped structures, which are embedded in the embedding groove 53 of the front panel 51 and the rear panel 52, so that the curtain plate 5 can be reliably fixed on the mesh chain 41 to reduce the shaking phenomenon; the front panel 51 and the rear panel 52 are connected at both ends and the middle position by bolts, which have high firmness and can be easily disassembled and replaced after being damaged, and have a high protection effect.

[0020] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
