Structural improvement of smoke-proof roller blinds

The present invention relates to a structural improvement of a smoke-proof roller blind, comprising a door frame, two guide rails disposed on two sides of the door frame, a roller blind cylinder disposed at an upper end of the door frame, and a driving unit disposed on an upper end side of the door frame and a lifting safety sensing device, the driving unit is controlled by a control unit connected to the smoke sensor or the fire protection system, and the driving unit is rotated by the chain transmission rolling cloth drum so that the rolling fabric wound on the rolling cloth drum The end portion can be lowered or raised by the two guide rails. On the rolling fabric, at least one emergency exit is provided according to the size of the area, and the inner and outer sides or one side of the emergency exit are respectively provided with the same as the rolling fabric. a woven layer made of fireproof material, so that when the fire smoke occurs, the driving unit drives the rolling fabric cylinder to rotate by the chain, so that the rolling fabric is lowered to close the door frame, and when the smoke is blocked, the person in the dangerous area can still Open the drapes from the emergency exit to the safe place, and enable the rescuers to smoothly enter and exit the fire for rescue.

According to the current technology, the population of the metropolitan area is increasing, and the homes and high-rise buildings are built. In order to achieve the safety of living, the fire-fighting equipment is constantly innovated, such as fire-fighting equipment, fire-fighting equipment and smoke-proof equipment, etc., which are most commonly used to isolate smoke. Most of the smoke prevention equipment adopts the anti-smoke roller blind made of fireproof cloth, and most of the conventional anti-smoke roller blinds are used to block the smoke when the fire causes smoke. It is used by 窜, but the design of the anti-smoke roller blind can be put down in the required time during the fire to prevent the spread of heat-insulating gas, smoke and fire, but once it is put down, it is still stuck in the fire. The escape of people on the field and the rescue work of rescuers, therefore, there are shortcomings in the conventional smoke prevention curtains that should be improved.

In view of the practical difficulties of the above-mentioned conventional anti-smoke roller blinds and the lack of improvement, the creator hopes to provide a breakthrough design to enhance the practical effect, which is devoted to research and design, and has been engaged in related research for many years. The professional technical knowledge and practical experience of product design and sales, as well as the results obtained from the research and design, finally developed a structural improvement of the smoke-proof roller blind to provide users.

The present invention relates to a structural improvement of a smoke-proof roller blind, comprising a door frame, two guide rails disposed on two sides of the door frame, a roller blind cylinder disposed at an upper end of the door frame, and a driving unit disposed on an upper end side of the door frame and a lifting safety sensing device, the driving unit is controlled by a control unit connected to the smoke sensor or the fire protection system, and the driving unit is rotated by the chain transmission rolling cloth drum so that the rolling fabric wound on the rolling cloth drum The end portion can be lowered or raised by the two guide rails, and a weight bottom rod is arranged at the end of the roller blind fabric, and a pressure touch sensing element is arranged at the bottom of the weight bottom rod, and the lifting safety sensing device is used when touching an object such as a human body. The control drive unit is stopped for safety purposes. On the rolling fabric, at least one emergency exit is provided according to the size of the area. In order to prevent the smoke from passing through the emergency exit when the fire occurs, the inner and outer sides of the emergency exit are Or one of the sides, each having the same appearance as the roller blind a woven layer made of fireproof material, so that when the fire smoke occurs, the driving unit drives the rolling fabric cylinder to rotate by the chain, so that the rolling fabric is lowered to close the door frame, and when the smoke is blocked, the person in the dangerous area can still Open the drapes from the emergency exit to the safe place, and enable the rescuers to smoothly enter and exit the fire for rescue.

The main purpose of this creation is on the roller blind fabric. According to the size of the area, at least one emergency exit is provided. In order to prevent the smoke from passing through the emergency exit when the fire occurs, on the inner and outer sides or one side of the emergency exit, Each of them is provided with a fabric layer made of the same fireproof material as the roller blind fabric, so that the fire smoke generates the drive unit to drive the roller blind cylinder to rotate by the chain, so that the roller blind fabric is lowered to close the door frame, and the smoke is blocked. People in the danger zone can still open the visor from the emergency exit to the safe place, and enable the rescuers to enter and exit the fire site for rescuers.

The second purpose of this creation is mainly at the bottom edge of the set of fabrics at the emergency exit. They are also provided with a bottom bar which can be matched with the weighted bottom bar provided at the end of the roller blind fabric. A bottom rod corresponding to the same side end is pivotally connected to one end of the weight of the weight bottom rod by a pivoting member, which can be a hinge or an elastic connecting piece, and the hinge can use a single hinge or two hinges To form two or more bendable joints to enhance the flexibility of the operation of the set of drapes.

A further object of the present invention is that the drive unit is controlled by a control unit connected to the smoke sensor or the fire protection system, and the fire sensor directly transmits the signal to the control unit when the fire occurs, and the control unit The instant start drive unit causes the roller blind to lower and close the door frame.

Another purpose of the present invention is to provide a weighted bottom rod at the end of the roller blind fabric, a pressure sensing element is arranged at the bottom of the weight bottom rod, and the pressure sensing element is connected to the lifting safety sensing device disposed on the door frame, and When the rolling contact fabric is lowered, when the pressure sensing element touches an object such as a human body, the lifting safety sensing device controls the driving unit to stop for safety purposes.

The other two purposes of this creation are in the guide rail of the creation, which is arranged in the gate groove of the guide rail, and is provided with a set of rails, in addition to increasing the smoothness of the upper and lower movement of the roller blind fabric, and can also be added as needed. Rails of appropriate thickness reduce the gap to a minimum, and it is not necessary to produce guide rails of gate brackets of different widths when manufacturing the guide rails, which can greatly reduce the production cost.

In order to make your review board more aware of the structural features and efficacy of this creation, we will cooperate with the schema and elaborate on it later.
