[0039] like Figures 1 to 3 As shown, a rolling shutter door anti-falling structure of this embodiment includes a limit assembly 100 and a control assembly. The limit assembly 100 is arranged on one side of the rolling shutter door. The limit assembly 100 includes a rotating block 110 and a limit seat 120. The rotating block 110 is provided with a limit rod 130 on the side of the lifting slide rail 11 of the rolling shutter door. The lifting slide rail 11 is provided with a limit hole 12 for the limit rod 130 to pass through. When the limit rod 130 rotates with the rotating block 110 to abut against the limit seat 120, the limit rod 130 is located in the limit hole 12 and the limit rod 130 is located on the lifting path of the rolling shutter door; the control assembly is connected to the driving component 13 of the rolling shutter door to control the switch of the driving component 13. The control assembly includes a switch component 210 arranged on one side of the limit assembly 100. When the limit rod 130 abuts against the limit seat 120, the limit rod 130 triggers the switch component 210 to control the driving component 13 to close.
[0040] In this embodiment, a limit assembly 100 is provided on one side of the rolling shutter door, specifically, the limit assembly 100 includes a rotating block 110, and a limit rod 130 is provided on the side of the rotating block 110 facing the lifting slide rail 11 of the rolling shutter door, and the limit rod 130 can be rotated with the rotating block 110 to pass through the limit hole 12 of the lifting slide rail 11, and abut against the limit seat 120 for limit fixing. At this time, the limit rod 130 is located on the lifting path of the rolling shutter door, so that the rolling shutter door can be limited and blocked when it falls due to a malfunction, preventing the rolling shutter door from falling directly and causing damage to people or objects, thereby effectively improving the reliability and safety of the rolling shutter door.
[0041] Furthermore, the rolling shutter door lowering structure also includes a control assembly, which is connected to the rolling shutter door's drive member 13 to control the opening and closing of the drive member 13, thereby controlling the raising and lowering of the rolling shutter door. Specifically, the control assembly includes a switch assembly 210 disposed on one side of the stop assembly 100. During the opening process of the rolling shutter door, the drive member 13 drives the rolling shutter door upward, and then operates the stop rod 130 to rotate into the stop hole 12 and abut against the stop seat 120 to achieve a fixed position. In this embodiment, the switch assembly 210 is mounted on the stop seat 120. When the stop rod 130 abuts the stop seat 120, the stop rod 130 simultaneously triggers the switch assembly 210 mounted on the stop seat 120 to control the closing of the drive member 13, thereby forcibly disconnecting the drive member 13 from driving the rolling shutter door. This effectively avoids the risk of the rolling shutter door closing or rising beyond the limit due to malfunction of the drive member 13 or malfunction of the drive member 13, thereby further improving the reliability and safety of the rolling shutter door.
[0042] In actual operation, the limit assembly 100 is installed on the wall on one side of the lifting slide rail 11, and the limit rod 130 and the rotating block 110 rotate along the wall, that is, the limit rod 130 and the rotating block 110 rotate in a plane parallel to the wall, so that during the rotation of the limit rod 130 and the rotating block 110, interference or collision with external equipment, objects or personnel is minimized, the interference of the rotation of the limit rod 130 and the rotating block 110 is reduced, and the smoothness of the rotation of the limit rod 130 and the rotating block 110 is improved.
[0043] In one embodiment, a control handle 140 is further provided on the rotating block 110. The control handle 140 is fixedly connected to the rotating block 110. The operator can control the rotation of the rotating block 110 through the control handle 140 to control the rotation of the limit rod 130. The operation is simple and convenient.
[0044] Furthermore, the rolling door anti-falling structure also includes a control rod 150, which is hingedly connected to the control handle 140. In actual operation, the stop assembly 100 is located on one side adjacent to the top of the rolling door, that is, the stop assembly 100 is at a certain height above the ground. This allows the stop assembly 100 to stop the rolling door at a higher position if it fails and falls, preventing the risk of damage to people or property caused by the falling rolling door. Thus, the control rod 150 increases the operator's distance from the control handle 140, facilitating operational control.
[0045] In one embodiment, the control rod 150 is provided with a connecting portion 151, and the connecting portion 151 is hinged to the control handle 140. Specifically, the control handle 140 is provided with a first hinge hole, and the connecting portion 151 is provided with a second hinge hole corresponding to the first hinge hole. The control handle 140 and the connecting portion 151 are hinged through a rotating shaft 160, and the rotating shaft 160 is respectively provided through the first hinge hole and the second hinge hole.
[0046] In one embodiment, fixing holes 161 are provided at both ends of the rotating shaft 160 in the axial direction. Fixing members 170 are inserted into the fixing holes 161. The fixing members 170 at both ends restrict the movement of the connecting portion 151 along the axial direction of the rotating shaft 160. In this embodiment, the fixing members 170 are twisted wires. By inserting the twisted wires into the fixing holes 161, the connecting portion 151 is restricted from both ends in the axial direction of the rotating shaft 160, thereby restricting the connection portion 151 to the rotating shaft 160. By using twisted wires, so-called fixing members 170, the wires are easy to obtain, easy to operate, and can be removed and replaced at any time, making it convenient for operators to operate. Of course, in other embodiments, other fixing members 170, such as pins, nails, rods, etc., can also be used. As long as they can achieve the purpose of restricting the movement of the connecting portion 151 along the axial direction of the rotating shaft 160, such designs are within the scope of protection of the present invention.
[0047] In one embodiment, the rolling door anti-falling structure further includes a locking seat 300, which includes a first locking seat and a second locking seat. The operating lever 150 is further provided with a locking member that is detachably connected to the first and second locking seats, respectively. The operating lever 150 is connected to the first and second locking seats to lock and secure the operating lever 150. When the operating lever 150 is connected to the first locking seat, the limiting rod 130 rotates to be located in the lifting path of the rolling door. When the operating lever 150 is connected to the second locking seat, the limiting rod 130 rotates out of the lifting path of the rolling door.
[0048] Specifically, when the rolling door is closed, the operating lever 150 is connected to the second locking seat. At this time, the limiting rod 130 is located outside the lifting path of the rolling door, and the rolling door can be raised normally to open. When the rolling door is opened, the operator releases the connection between the operating lever 150 and the second locking seat, controls the rotating block 110 via the operating lever 150 to rotate the limiting rod 130 to the lifting path of the rolling door, and locks the operating lever 150 to the first locking seat to keep the limiting rod 130 fixed in the lifting path of the rolling door. Conversely, when the rolling door needs to be closed, the operating lever 150 is released from the first locking seat, controls the rotating block 110 via the operating lever 150 to rotate the limiting rod 130 to the lifting path of the rolling door, and locks the operating lever 150 to the second locking seat to keep the limiting rod 130 fixed outside the lifting path of the rolling door. At this time, the rolling door can be lowered normally to close.
[0049] In actual operation, the first locking seat includes a first locking block 310, and the second locking seat includes a second locking block 320. The control rod 150 is provided with a locking ring 152 for being respectively sleeved on the first locking block 310 and the second locking block 320. The locking ring 152 is respectively sleeved on the first locking block 310 and the second locking block 320 to realize the control rod 150 being respectively clamped and fixed with the first locking block 310 and the second locking block 320.
[0050] In one embodiment, the switch member 210 is a proximity switch or solenoid valve 210a, which is installed on the limit seat 120. When the limit rod 130 rotates to abut against the limit seat 120, the limit rod 130 triggers the proximity switch or solenoid valve 210a, so as to control the closing of the driving member 13 through the proximity switch and the solenoid valve 210a, thereby cutting off the driving of the rolling door. Figure 4 and Figure 5 As shown, in this embodiment, the specific switch component 210 is configured as a solenoid valve 210a, and the limit seat 120 includes a mounting plate 121, and the mounting plate 121 is provided with an L-shaped limit frame 122, and the horizontal rod 1221 of the limit frame 122 is in contact with the limit rod 130 to limit and fix the limit rod 130, and a limit groove 123 for placing the limit rod 130 is formed between the horizontal rod 1221 and the vertical rod 1222 of the limit frame 122 and the mounting plate 121, and the limit groove 123 can provide a certain protection for the limit rod 130. The solenoid valve 210a includes a shell 211 installed on the mounting plate 121, and a contact switch 212 is provided on the top of the shell 211. The horizontal height of the contact switch 212 is equal to or slightly higher than the horizontal height of the abutment point between the limit rod 130 and the horizontal rod 1221, so that when the limit rod 130 rotates to abut against the limit seat 120, the limit rod 130 simultaneously abuts against the contact switch 212 to trigger the solenoid valve 210a.
[0051] Of course, in addition to this embodiment, other switch components 210 such as automatic reset button switches can also be used, as long as they can be automatically triggered when the limit rod 130 is rotated to the lifting path of the rolling door, so as to further improve the overall anti-falling effect and improve the reliability and safety of the overall structure.
[0052] In one embodiment, Figure 6 and Figure 7 As shown, the rolling door lowering structure also includes a sensing operation component, which includes a sensing switch 410 and an operating driver. The sensing switch 410 is set on a side adjacent to the top of the lifting slide 11 to sense the position information of the rolling door and feed the position information of the rolling door to the operating driver. The operating driver is connected to the rotating block 110 to drive the rotating block 110 to rotate. During the operation of opening the rolling door, when the rolling door rises to a certain height and triggers the sensing switch 410, the sensing switch 410 feeds the position information of the rolling door to the operating driver. The operating driver drives the rotating block 110 to rotate and drives the limit rod 130 to the lifting position of the rolling door, achieving an automatic anti-falling effect and avoiding the risk of the operator forgetting to operate.
[0053] Specifically, if Figures 6 to 8 As shown, the rolling shutter door lowering structure also includes a support assembly 500, which includes a support frame 510 for supporting the position-limiting assembly 100 and the sensing operation assembly. The operating drive is a motor 420, the base 421 of which is mounted on the support frame 510. The output shaft of the motor 420 is in transmission connection with the rotating block 110. The support frame 510 also includes a rotating base 520, which is provided with a rotating groove 521 for the rotating block 110 to rotate, ensuring the stability of the rotating block 110. Furthermore, in actual operation, a lubricant such as lubricating oil can be placed in the rotating groove 521 to improve the smoothness of the rotating block 110. Furthermore, the support frame 510 also includes support reinforcement ribs 530, which enhance the support stability of the support frame 510, thereby ensuring the stability of the position-limiting assembly 100 and the sensing operation assembly.
[0054] On the other hand, Figure 9 and Figure 10 As shown, a rolling door is provided, including a rolling door assembly 1 and the above-mentioned rolling door anti-falling structure 2. The rolling door assembly 1 includes a rolling door body 10, a driving member 13 and a lifting rail 11. The rolling door body 10 includes a door curtain portion 10a and a reeling portion 10b. The driving member 13 is connected to the rolling door body 10 in a transmission manner to reel the door curtain portion 10a into the reeling portion 10b. Among them, there are two lifting rails 11, and the rolling door anti-falling structure 2 is respectively arranged on one side of the two lifting rails. The opening and closing states of the rolling door body 10 are respectively as shown in FIG. Figure 9 and Figure 10 shown.
[0055] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
