Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of roller shutter door accessories, especially to a flexible roller shutter. BACKGROUND

[0002] The flexible roller shutter is usually a soft roller shutter with a flexible smoke-retaining vertical wall, which is generally applied to large places such as shopping malls and supermarkets, and blocks the spread of smoke during a fire through the flexible smoke-retaining vertical wall to achieve the effect of controlling the fire.

[0003] However, the existing flexible roller shutter generally only connects a clamping seat to the lower end of the flexible smoke-retaining vertical wall to increase the weight of the flexible smoke-retaining vertical wall, so as to ensure that the flexible smoke-retaining vertical wall can maintain a vertical state during lowering and use. However, in summer or winter, when the temperature difference between indoor and outdoor is large, the air conditioning in the shopping mall is usually turned on at a large air volume. If the flexible roller shutter is set close to the air outlet of the air conditioner, the flexible smoke-retaining vertical wall is easily blown, which reduces the smoke-retaining effect. SUMMARY

[0004] The utility model discloses a flexible roller shutter to solve the problems in the prior art.

[0005] To achieve the above object, the utility model adopts the following technical scheme: a rotating shaft, a flexible smoke-retaining vertical wall and at least two chains are included.

[0006] The rotating shaft is arranged at a wall hole of a wall.

[0007] One end of the flexible smoke-retaining vertical wall is fixedly connected with the rotating shaft.

[0008] The chains are distributed on the surface of the flexible smoke-retaining vertical wall.

[0009] The other end of the flexible smoke-retaining vertical wall and the other end of the chain are connected with a clamping strip.

[0010] As a further description of the above technical scheme: one end of the rotating shaft is connected with a tubular motor, and the tubular motor is fixedly arranged on the wall.

[0011] As a further description of the above technical scheme: at least two guide rails are arranged on the wall, and the guide rails are vertically arranged.

[0012] As a further description of the above technical scheme: the guide rails are located on both sides of the flexible smoke-retaining vertical wall.

[0013] As a further description of the above technical scheme: a blocking strip is arranged on one end of the flexible smoke-retaining vertical wall close to the rotating shaft, and the blocking strip is located in the guide rail.

[0014] As the further description of the above technical solutions: the blocking strip is penetrated through the flexible smoke blocking curtain wall by a bolt.

[0015] As the further description of the above technical solutions: the flexible smoke blocking curtain wall adopts silica gel fireproof cloth.

[0016] As the further description of the above technical solutions: one end of the chain close to the rotating shaft is fixedly connected with the flexible smoke blocking curtain wall.

[0017] As the further description of the above technical solutions: the chains are distributed on the same side of the flexible smoke blocking curtain wall.

[0018] As the further description of the above technical solutions: the chains are distributed on different sides of the flexible smoke blocking curtain wall.

[0019] The utility model has the advantages of the following beneficial effects:

[0020] The chain arranged on the surface of the flexible smoke blocking curtain wall can better ensure that the flexible smoke blocking curtain wall can be kept in the vertical position during recycling or lowering, so that the situation that the flexible smoke blocking curtain wall is blown up due to strong wind during fire and the smoke blocking effect is reduced can be avoided.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0028] With reference to Figures 1-3 An embodiment provided by the present application comprises a rotating shaft 1, a flexible smoke blocking vertical wall 2 and at least two chains 3. The rotating shaft 1 is arranged at a wall hole of a wall 5. One end of the flexible smoke blocking vertical wall 2 is fixedly connected with the rotating shaft 1. The chains 3 are distributed on the surface of the flexible smoke blocking vertical wall 2. The other end of the flexible smoke blocking vertical wall 2 and the other end of the chains 3 are connected with a clamping strip 4. The chains 3 arranged on the surface of the flexible smoke blocking vertical wall 2 increase the weight of the flexible smoke blocking vertical wall 2, enhance the wind resistance of the flexible smoke blocking vertical wall 2, improve the smoke blocking effect in the case of large wind force, and better ensure the recycling and lowering of the flexible smoke blocking vertical wall 2, so as to effectively avoid the situation that the flexible smoke blocking vertical wall 2 is stuck during recycling or lowering.

[0029] The chains 3 are distributed on the same side of the flexible smoke blocking vertical wall 2. The at least two chains 2 are respectively located at different positions of the same side. The end of the chain 3 close to the rotating shaft 1 is fixedly connected with the flexible smoke blocking vertical wall 2, so that the chain 3 and the flexible smoke blocking vertical wall 2 can better adhere to each other, and the mechanical properties of the chain 3 to the flexible smoke blocking vertical wall 2 in the vertical direction are better ensured.

[0030] At least two guide rails 7 are arranged on the wall 5. The guide rails 7 are vertically arranged. The guide rails 7 are respectively located at the two sides of the flexible smoke blocking vertical wall 2. The middle part of the guide rail 7 is provided with a groove, which is used for arranging the side edge of the flexible smoke blocking vertical wall 2 and the two end faces of the clamping strip 4, so as to better ensure that the flexible smoke blocking vertical wall 2 can move along the fixed path during recycling or lowering. The end of the flexible smoke blocking vertical wall 2 close to the rotating shaft 1 is provided with a blocking strip 8. The blocking strip 8 is located in the guide rail 7. The blocking strip 8 penetrates the flexible smoke blocking vertical wall 2 through bolts. The flexible smoke blocking vertical wall 2 is made of silica gel fireproof cloth. After the two blocking strips 8 are connected through bolts, the two blocking strips 8 are located at two different surfaces of the flexible smoke blocking vertical wall 2. The blocking strip 8 is clamped with the guide rail 7, so as to better ensure the moving path of the flexible smoke blocking vertical wall 2.

[0031] One end of the rotating shaft 1 is connected with a tubular motor 6. The tubular motor 6 is fixedly arranged on the wall 5. The output shaft of the tubular motor 6 is connected with one end of the rotating shaft 1. The rotation of the rotating shaft 1 is driven by the tubular motor 6, so as to complete the recycling and lowering of the flexible smoke blocking vertical wall 2. It should be noted that the specific structure and working principle of the control, connection mode and installation mode of the tubular motor 6 and the rotating shaft 1 are the existing technology, and thus will not be described herein.

[0032] Embodiment two:

[0033] With reference to Figure 4 Unlike the above embodiment, the chain 3 is distributed on different sides of the flexible smoke-retarding curtain 2, so that both surfaces of the flexible smoke-retarding curtain 2 are provided with the chain 2, which can ensure that in both forward and reverse directions, the wind resistance of the flexible smoke-retarding curtain 2 can be improved.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
