Description

Rolling door support device

The invention relates to a rolling door supporting device, in particular to a supporting device capable of improving the comprehensive compressive strength of the rolling door, thereby strengthening the disaster prevention and external force impact supporting capability of the inner and outer sides of the rolling door, thereby ensuring the safety of the rolling door access control. By.

As shown in the first figure, a schematic plan view of the conventional rolling door 1 in which the supporting device 2 is in the closed state is installed, wherein the rolling door 1 is composed of a plurality of rolling shutters 10, and the top of the rolling door 1 is provided with a rotating shaft. The chassis 11 utilizes the rotation of the motor shaft (which is a conventional structure, which is not shown in the drawings) in the shaft housing 11 to wind the roller door 1 to open the door or release the door, and the roll door 1 A door rail 12 is disposed on each side of the door, so that the roll door 1 can slide up and down along the door rail 12; when the roll door 1 is lowered and closed, the bottom of the roll door 1 will abut against the ground, such a roll door 1 structure, When the outer side is hit by a strong wind, or when an external force is applied (for example, the tool is opened from the bottom), it is easily broken and opened, and the anti-theft and windproof functions are lost. Therefore, in order to reinforce the support strength of the roll door 1 It is a support device 2 that can increase the strength of the roller door 1.

The supporting device 2 is mounted adjacent to the inner side of the rolling door 1 and is mainly composed of a pivoting seat 20, a plurality of telescopic links 21 and a transverse link 23, and when the supporting device 2 is deployed (ie When the rolling door 1 is in the closed state, the pivoting seat 20 is located at a central position, and the plurality of telescopic links 21 are centered on the pivoting base 20 and radially distributed from the inside to the outside. One end of the telescopic link 21 The pivoting seat 20 is pivotally connected to the pivoting end of the rod end 22 of the telescopic link 21 at the other end. 221, the pivoting end 221 is pivotally connected to the two sides of the lower crossbar 24 and the upper crossbar 25, and the transverse connecting rod 23 is laterally fixed to the pivoting seat 20, and the two ends of the transverse connecting rod 23 A guide wheel 231 is disposed. The guide wheel 231 is disposed in a guide rail 121. The support device 2 composed of the above is attached to the inner side of the roll door 1 so that the outer side of the roll door 1 is attacked by an external force (such as strong wind). Or acting, the support device 2 can be supported by the support device 2 to increase its compressive strength, thereby ensuring that the roll door 1 is not damaged or deformed; when the roll door 1 is opened (as shown in the second figure), The support device 2 will synchronously cooperate with the roll door for upward movement. At this time, the lower cross bar 24 and the transverse link 23 move upward, and the rod body 22 of the telescopic link 21 will be inwardly retracted with the upward movement until The roll door 1 receives the uppermost door opening position, and the upper cross bar 25, the lower cross bar 24 and the transverse link 23 of the support device 2 are paralleled together; the structure of the support device 2 can indeed achieve the auxiliary roll door 1 resisting the external force from the outer side, but in terms of the actual use of the example, there are still some shortcomings, as Said below:

1. The source of the external force applied to the rolling door 1 is not limited to the outer side of the rolling door 1. For example, when a fire occurs, a rolling door having a fireproof function installed inside the building, in order to block the spread of the fire, the rolling door 1 also faces a strong airflow attack on the inner side. This conventional support device 2 does not easily exert the effect of resisting and supporting the external force from the inner side of the roll door 1.

2. The telescopic link 21 used in the conventional support device 2 has a high material cost, and the cylinder resistance of the telescopic link 21 itself is large at the time of folding, which affects the smoothness of the folding operation.

In view of this, the inventor of the present invention has finally completed the roll door supporting device of the present invention after numerous research and improvement, that is, the object of the present invention is to provide a supporting device capable of improving the comprehensive compressive strength of the rolling door, thereby strengthening the roll. The disaster prevention and external force impact support capability of the inner and outer sides of the door ensures the security of the door.
