Abstract

The utility model discloses a wind-resistant device for a rolling shutter door. The utility model is mainly composed of a hook body and a lock catch rail which are respectively arranged on the edge of the rolling shutter door and a door frame. The device is used for the rolling shutter door or the improvement of a traditional rolling shutter door and provides a wind-resistant effect of the rolling shutter door; the condition that the rolling shutter door can be still used as usual when subjected to wind is ensured.

Description

The wind-proof device of rolling door

Technical field

The utility model relates to the wind-proof device of rolling door.

Background technology

Traditional rolling door does not have wind-proof device, the edge 1 of rolling door and the matching relationship of doorframe 2, and as shown in Figure 3, promptly the edge 1 of rolling door directly is plugged in the doorframe 2; When wind-engaging, rolling door occurs bending and deformation under the effect of wind-force, and simultaneously, edge 1 desire that gives rolling door is thrown off the pulling force of doorframe 2, as shown in Figure 4; When increasing along with wind-force, pulling force also increases gradually, and when wind-force reached certain limit (high wind), powerful pulling force was about to the edge 1 of rolling door and pulls out from doorframe 2, as shown in Figure 5, causes in rolling door integral body and the doorframe 2 and throws off, and can't use.

The utility model content

The purpose of this utility model is to provide a kind of wind-proof device of rolling door, so that rolling door windproof effect to be provided, guarantees that rolling door still can use as usual when wind-engaging.

For reaching above-mentioned purpose, solution of the present utility model is:

The wind-proof device of rolling door mainly is made up of coupler body that cooperatively interacts and snap close track, and coupler body and snap close track are separately positioned on the edge and doorframe of rolling door.

Wherein, above-mentioned snap close track can be one-body molded in doorframe, also can with doorframe divide body formed, and by being bolted in the doorframe.

The edge of above-mentioned rolling door is provided with slide block, and this slide block just is between the edge and doorframe of rolling door.

After adopting said structure, the utility model is applied to improve in the rolling door or to traditional rolling door, cooperate with the snap close track, just the edge of rolling door can be latched in the doorframe by coupler body, when wind-engaging, no matter wind-force is much, how rolling door occurs bending and deformation, and coupler body all cooperates with the snap close track all the time, make the edge of rolling door latch in the doorframe all the time, can't throw off, thereby rolling door windproof effect is provided, guarantee that rolling door still can use as usual when wind-engaging.

In addition, the utility model is owing to be provided with slide block between the edge of rolling door and doorframe, so, can make coupler body location, thereby guarantee to have spacing between coupler body and the snap close track when calm, make the edge and the frictional force between the doorframe of rolling door little, make things convenient for the unlatching of rolling door.

The specific embodiment

See also shown in Figure 1ly, the wind-proof device of the rolling door that the utility model discloses mainly is made up of coupler body 3 that cooperatively interacts and snap close track 4.

Wherein, coupler body 3 and snap close track 4 are separately positioned on the edge 1 and doorframe 2 of rolling door.Specifically, coupler body 3 can be one-body molded on the edge 1 of rolling door (this paper does not give diagram), also moulding separately, and be fixed on by bolt 5 on the edge 1 of rolling door, as shown in Figure 1.And in like manner, snap close track 4 can be one-body molded in doorframe 2 (this paper does not give diagram), also can be body formed with doorframe 4 minutes, and be fixed in the doorframe 2 by bolt 5.

Like this, the utility model applies to improve in the rolling door or to traditional rolling door, cooperates with snap close track 4 by coupler body 3, when wind-engaging, as shown in Figure 2, no matter wind-force is much, how flexural deformation of rolling door, coupler body 3 all cooperates with snap close track 4 all the time, make the edge 1 of rolling door latch in all the time in the doorframe 2, can't throw off, thereby rolling door windproof effect is provided, guarantee that rolling door still can use as usual when wind-engaging.

And the concrete shape of coupler body 3 and snap close track 4 is not subjected to the restriction of this paper and figure in the utility model, so long as make the edge 1 of rolling door latch in all the time in the doorframe 2 and the structure that can't throw off by the mode of mutual hook, all should fall into the category of this case.

In addition, cooperate shown in Figure 1 again, also be provided with slide block 5 on the edge 1 of rolling door, this slide block 5 just is between the edge 1 and doorframe 2 of rolling door, can play the effect of location coupler body 1, when calm, have spacing between coupler body 3 and the snap close track 4, make the edge 1 and the frictional force between the doorframe 2 of rolling door little, thereby make things convenient for the unlatching of rolling door.

Claims
