DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] Reference Figure 1 and Figure 2 , is a double-curtain rolling door anti-slip protection device 1 disclosed in the present invention, comprising a fixing unit 10 and a blocking plate 20; one end of the fixing unit 10 is connected to the door column 2, and the other end of the fixing unit 10 passes through the gap between the outer rolling door slide rail 3 and the inner rolling door slide rail 4 and is connected to one end of the blocking plate 20, and the blocking plate 20 can rotate relative to the fixing unit 10; when the blocking plate 20 is in a non-protective state, the blocking plate 20 is located on the side of the fixing unit 10 away from the outer rolling door slide rail 3, and the end of the blocking plate 20 away from the fixing unit 10 is along the height direction of the door column 2 Extend downward; when the blocking plate 20 is in the protective state, rotate the blocking plate 20 so that the blocking plate 20 is placed on the top surface of the fixed unit 10, and the end of the blocking plate 20 away from the fixed unit 10 extends along the height direction perpendicular to the door column 2 to the outer rolling door slide rail 3 to prevent the outer rolling door from sliding out of control; such an arrangement can prevent the safety hazard of personal injury and property loss caused by the uncontrolled sliding of the outer rolling door; at the same time, the outer rolling door of the double-curtain rolling door is always open and plays a role of anti-slip safety protection, and the inner soft curtain is always closed to meet the use requirements of windproof and heat preservation functions.

[0020] When the blocking plate 20 is in a non-protective state, the blocking plate 20 is perpendicular to the ground under the action of its own gravity; when the blocking plate 20 is in a protective state, the blocking plate 20 is arranged parallel to the horizontal plane, and the extension direction of the blocking plate 20 is perpendicular to the extension direction of the outer rolling door sliding rail 3.

[0021] The blocking plate 20 may be made of a steel plate; of course, the blocking plate 20 may also be made of an iron plate or other metal plates.

[0022] Specifically, the height range between the bottom surface of the fixing unit 10 and the ground is 2m-2.1m; that is, the installation height of the anti-slip protection device 1 for the double-curtain rolling door is between 2m-2.1m.

[0023] It should be noted that, during the installation process, the anti-slip protection device 1 is installed at the same height of the doorposts 2 on the left and right sides of the rolling door, and the welding position with the doorpost 2 is repainted with structural paint after installation.

[0024] The use process of the anti-slip protection device 1 for the double-curtain rolling door provided in this embodiment is as follows: Figure 2 Taking the shown orientation as an example, when the blocking plate 20 is in the protective state, the blocking plate 20 is manually rotated 270 degrees clockwise so that the blocking plate 20 is placed on the top surface of the fixed unit 10, and the end of the blocking plate 20 away from the fixed unit 10 extends along the height direction perpendicular to the door column 2 to the outer rolling door slide rail 3, that is, it is blocked at the outer rolling door slide rail 3 to effectively prevent the safety hazard of the outer rolling door causing injuries to people and property losses due to uncontrolled sliding.

[0025] When the outer rolling door needs to be completely closed, the blocking plate is manually rotated 270 degrees counterclockwise to rotate the blocking plate 20 to the side of the fixing unit 10 away from the outer rolling door slide rail 3. At this time, the blocking plate 20 is vertical to the ground under the action of gravity.

[0026] It should be noted that the anti-slip protection device 1 for the double-curtain rolling door is arranged in the gap between the outer rolling door sliding rail 3 and the inner rolling door sliding rail 4. The anti-slip protection device 1 has no effect on the normal opening and closing of the inner rolling door, and can achieve the safety requirements of the outer rolling door of the double-curtain rolling door (outer hard curtain, inner soft curtain) being normally open, and the inner rolling door being normally closed for windproof and heat preservation.

[0027] Furthermore, in this embodiment, the fixing unit 10 includes an L-shaped support frame 11 and a connecting frame 12, one end of the L-shaped support frame 11 is connected to the door column 2, the other end of the L-shaped support frame 11 is connected to one end of the connecting frame 12, the other end of the connecting frame 12 passes through the gap between the outer rolling door slide rail 3 and the inner rolling door slide rail 4 and is connected to one end of the blocking plate 20, and the blocking plate 20 can rotate relative to the connecting frame 12.

[0028] Among them, the L-shaped support frame 11 includes a horizontal rod and a vertical rod, one end of the horizontal rod is connected to one end of the vertical rod to form an L shape, the vertical rod is connected to the door post 2, and the end of the horizontal rod away from the vertical rod extends along a direction perpendicular to the height of the door post 2 and is connected to one end of the connecting frame 12.

[0029] Specifically, the extension direction of the vertical rod is arranged parallel to the height direction of the door post 2 .

[0030] Wherein, the L-shaped support frame 11 is made of channel steel.

[0031] Taking a plane parallel to the extending direction of the horizontal rod as a cross section, the cross section of the connecting frame 12 is L-shaped.

[0032] The connecting frame 12 includes a horizontal plate 121 and a vertical plate 122 . The top of the vertical plate 122 is connected to the bottom surface of one end close to the horizontal plate 121 , and the end of the horizontal rod away from the vertical rod is connected to the vertical plate 122 .

[0033] It should be noted that the welding point between the horizontal rod and the vertical plate 122 must be able to withstand a force greater than the impact force of the outer rolling door sliding out of control.

[0034] Exemplarily, the connecting frame 12 can be made of angle steel. Of course, the connecting frame 12 can also be welded from steel plates.

[0035] Furthermore, in the present embodiment, two rotating sleeves 123 are provided on the outer side wall of the end of the connecting frame 12 away from the L-shaped supporting frame 11, and the two rotating sleeves 123 are both provided on the side of the connecting frame 12 away from the outer rolling door slide rail 3, and the two rotating sleeves 123 are spaced apart along the extension direction of the connecting frame 12, and the center lines of the two rotating sleeves 123 are both provided parallel to the extension direction of the connecting frame 12.

[0036] Specifically, the two rotating sleeves 123 are both disposed on a side of the horizontal plate 121 away from the vertical plate 122 .

[0037] It should be noted that the welding point between the rotating sleeve 123 and the horizontal plate 121 must be able to withstand a force greater than the impact force of the outer rolling door sliding out of control.

[0038] Among them, a rotating rod adapted to the rotating sleeve 123 is provided at one end of the blocking plate 20, and the end of the blocking plate 20 is connected to the outer peripheral wall of the middle position of the rotating rod extending along the center line direction of the rotating rod, and the two ends of the rotating rod are respectively inserted into the two rotating sleeves 123, and the rotating rod can rotate relative to the rotating sleeve 123; the blocking plate 20 is rotated so that the blocking plate 20 drives the rotating rod to rotate in the rotating sleeve 123.

[0039] Specifically, the extending direction of the blocking plate 20 is perpendicular to the center line of the rotating rod.

[0040] During use, the two opposite ends of the rotating rod are respectively inserted into the two rotating sleeves 123 , and the rotating rod can rotate relative to the rotating sleeves 123 .

[0041] Exemplarily, the rotating rod can be made of round steel. Of course, the rotating rod can also be made of a round iron pipe made of iron.

[0042] It should be noted that the welding point between the blocking plate 20 and the rotating rod must be able to withstand a force greater than the impact force of the outer rolling door sliding out of control.

[0043] When the blocking plate 20 is in the protection state, the blocking plate 20 is placed on the top surface of the horizontal plate 121. At this time, the extending direction of the blocking plate 20 is parallel to the extending direction of the horizontal rod. When the blocking plate 20 is in the non-protection state, the blocking plate 20 is located on the side of the horizontal plate 121 away from the vertical plate 122. At this time, the blocking plate 20 is parallel to the vertical plate 122.

[0044] The use process of the anti-slip protection device 1 for the double-curtain rolling door provided in this embodiment is as follows: Figure 2 Taking the position shown as an example, when the blocking plate 20 is in the protection state, the blocking plate 20 is manually rotated, and the blocking plate 20 is rotated 270 degrees clockwise with the center line of the rotating rod as the axis, so that the blocking plate 20 is placed on the top surface of the horizontal plate 121, and the end of the blocking plate 20 away from the rotating rod extends along the length direction of the horizontal rod to the outer rolling door slide rail 3, that is, it is blocked at the outer rolling door slide rail 3 to effectively prevent the outer rolling door from sliding out of control and causing safety hazards such as injuries to personnel and property losses. When the outer rolling door needs to be completely closed, the blocking plate is manually rotated, and the blocking plate 20 is rotated 270 degrees counterclockwise with the center line of the rotating rod as the axis, so that the blocking plate 20 is rotated to the side of the horizontal plate 121 away from the vertical plate 122. At this time, the blocking plate 20 is vertical to the ground under the action of gravity.
