Description

Electric roller door anti-fall safety mechanism

The present invention relates to a safety mechanism for an iron roll door, in particular to a stop mechanism which is arranged on the side of the roll door rail and can control the power supply, and can avoid the creation of an electric roller shutter safety mechanism for a sudden falling of a rolling door in a static state. .

The electric iron roll door is a kind of equipment installed in the factory, shop or main entrance and exit of the house. As shown in Fig. 1, the main structure of the common iron roll door includes the roll door (10), the roll door shaft (11) and the transmission mechanism. (12) and an electric motor (13), which drives the chain (14) to drive the rolling door shaft (11) through the transmission mechanism (12), so that the rolling door (10) is along the guide rails on both sides (15) ) Swipe up or down to form the purpose of opening and closing the entrance and exit.

The construction of the electric iron roller door is not complicated, but there is still an accident that the roller door (10) suddenly and quickly falls during the operation or at rest, the reason is nothing more than the gear collapse in the transmission mechanism (12), the chain (14) Fracture, or brake failure, causing the heavy iron roll door to lose its clamping force and suddenly fall quickly, which is very likely to cause personal injury or property damage.

Although it is dangerous to fall accidents in the operation of electric iron shutter doors, after all, when the iron shutter door is opened and closed, the personnel will not stand under the iron gate, but the iron roller door will suddenly fall when it is at rest, and it is easy to make it not known below. The staff did not respond well and caused serious personal accidents. Therefore, how to provide a mechanism that can protect the personal safety with the simplest structure and the most accurate operation, effectively avoiding the crisis of the static iron roll door without warning, and thus becomes the subject of this creation.

In view of this, the main purpose of this creation is to provide an electric roller shutter safety mechanism that can be easily and effectively prevented from falling down.

In order to achieve the above object, the present invention provides an electric roller shutter safety mechanism including at least one safety switch and at least one stop structure disposed at a suitable height near the roller door guide rail; the safety switch is connected in series to the electric coil The power circuit of the door; the stop structure has strength, the movable position to the roll door path, and is pressed to the safety switch to cause the power circuit to form an open circuit.

The electric rolling door anti-falling safety mechanism, wherein the stopping structure is composed of a resisting arm, a stopping portion, a shaft portion and a shaft seat, the shaft portion is formed on the fixed end of the anti-force arm, and the stopping portion is vertically protruded from the The movable arm movable end is mounted on a vertical surface near the rolling door guide rail, and the shaft portion is axially coupled to the shaft seat.

The advantage of the electric roller shutter safety mechanism is that the safety switch controls the power circuit through the stop structure to prevent the operator from operating the electric roller door incorrectly. When the rolling door failure suddenly falls, the rolling door will be blocked by the blocking portion, interrupting the situation of the rolling door falling, and achieving the effect of protecting personnel and property, which is quite progressive.

In order to provide a complete description of the structural features, technical contents, functions, and other features of the present invention, the following is a detailed description of the preferred embodiments.

Please refer to FIG. 2 , which is a schematic diagram of a preferred embodiment of the present invention. The safety mechanism includes a safety switch (20) and a stop structure (30), wherein the safety switch (20) is a normally open switch that is connected in series with the power circuit (21) of the electric rolling door; the blocking structure (30) is a member body having strength and is made of a resistance arm (31) The stopping portion (32), the shaft portion (33) and the shaft seat (34) are formed. The shaft portion (33) is formed on the fixed end of the resistance arm (31), and the stopping portion (32) is vertically protruded. At the movable end of the resistance arm (31), the shaft seat (34) is mounted at an elevation of a suitable height near the roll door guide (41), and the resistance arm (31) is axially coupled to the shaft by a shaft portion (33) Seat (34) and can move horizontally.

As shown in Fig. 2, the state when the electric roller shutter can be opened and closed is simultaneously displayed. Wherein, the angle of the anti-force arm (31) is moved away from the guide rail (41) to move the blocking portion (32) away from at least the rolling door (40). In this state, the anti-force arm (31) does not press the safety switch. (20) The electric rolling door power circuit (21) is closed, so that the relevant person can naturally operate the electric rolling door to open and close without being standing under the electric rolling door.

Please refer to the third figure as shown in the figure to reveal the implementation of the electric roller door safety mechanism. The figure shows that the electric roller door is in the static state of opening, wherein the resistance arm ( The angle of 31) is close to the guide rail (41), so that the stop portion (32) corresponds to the guide rail path, and the resistance arm (31) is pressed to the safety switch (20) to make the power circuit (21) form an open circuit. At this time, in the state where the electric power circuit is disconnected, the electric rolling door has a problem of preventing other persons from operating the electric rolling door by manual or remote control.

Finally, please refer to Figure 4, which is a schematic diagram showing the action of the electric roller shutter safety mechanism. As mentioned before, this creation is mainly applied to the static state after the electric rolling door is opened. At this time, in the state where the electric winding door is disconnected in the power circuit (21), no other personnel mistakenly open and close the rolling door. When unfortunately, the sudden failure of the electric rolling door failure occurs, as shown in the figure, the rolling door (40) that is descending soon will be blocked by the stopping portion (32), completely stopping the movement of the rolling door (40) falling. According to this, the purpose of protecting personnel safety and property damage is achieved.

Through the implementation of the above structure, it can be found that the present electric roller shutter safety mechanism has at least the following advantages: 1. The safety switch controls the power circuit to be shut off through the blocking structure to prevent the operator from operating the electric rolling door by mistake. 2. When the roll door failure suddenly falls, the roll door will be blocked by the stop part, interrupting the situation of the roll door falling, and achieving the effect of protecting personnel and property.

In summary, the creation of the electric roller shutter safety mechanism has indeed achieved the preset purpose, which has met the needs of the industry, and has filed a patent application according to law. However, the present invention has been disclosed in the preferred embodiment described above. However, the size, shape, or quantity of the drawings are not intended to limit the present invention, and any person skilled in the art may modify or modify it without departing from the spirit and scope of the present invention. It is subject to the definition of the scope of the patent application attached.
