DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1-14 As shown, the utility model provides a technical solution: a rolling shutter door with anti-pry sensing, comprising a door frame 1, a rolling shutter door 2 installed in the door frame 1, a lock body 3 installed on the rolling shutter door 2, and a curtain foot 4 arranged at the end of the rolling shutter door 2, an anti-pry mechanism 5 is arranged in the rolling shutter door 2, and sensing mechanisms 6 are arranged on the left and right sides of the rolling shutter door 2;

[0040] The anti-pry mechanism 5 includes a housing 51, a handle 55, a U-shaped block 56, and a rotating block 52, a rotating rod 53, and a round rod 57 respectively arranged in the housing 51. One end of the round rod 57 is connected to the lock body 3, and the other end is fixedly connected to the outer wall of the rotating block 52. The two ends of the rotating block 52 are rotatably connected to one end of the rotating rod 53 through a pin shaft 1. The other end of the rotating rod 53 is rotatably connected to a bolt rod 54 through a pin shaft 2. The other end of the bolt rod 54 passes through the housing 51 and the U-shaped block 56 in sequence, and the outer wall of the bolt rod 54 is slidably connected to the inner wall of the U-shaped block 56. The U-shaped block 56 is fixedly connected to the outer wall of the rolling door 2. The handle 55 passes through the housing 51 and extends to the outer wall of the rotating block 52 for fixed connection.

[0041] The key can be inserted into the lock body 3 from the outside to rotate it, thereby driving the round rod 57 to rotate, and the round rod 57 will drive the rotating block 52 to rotate. The rotation of the rotating block 52 will drive the rotating rod 53 to deflect, thereby driving the bolt rod 54 to move left and right, and then the bolt rod 54 is inserted into or pulled out of the through opening 614 to lock or unlock the rolling door 2. When the bolt rod 54 is inserted into the through opening 614, the through opening 614 will strongly hinder the bolt rod 54 from moving upward, thereby preventing the rolling door 2 from moving upward, so that the rolling door 2 cannot be pried by human power, thereby achieving the purpose of anti-prying.

[0042] The sensing mechanism 6 includes a guide piece 1 62, a strong magnet 1 63, and a guide piece 2 64. The left and right sides of the door frame 1 are provided with a cavity 61 and a through hole 614. The size of the through hole 614 provided on the door frame 1 matches the cross section of the bolt rod 54, so that the bolt rod 54 can enter the through hole 614 conveniently, which can not only play an anti-pry role, but also enable the sensing mechanism 6 to perform an induction alarm when pried by an external force, thereby achieving a better anti-pry effect. The guide piece 1 62 is fixedly embedded in the far side of the bolt rod 54. At the bottom of one end of the rotating rod 53, a guide piece 62 is embedded in the bottom of the bolt rod 54 to facilitate the bolt rod 54 to be inserted into the through opening 614. The guide piece 62 connects the positive electrode sheet 612 with the negative electrode sheet 613. The inner wall of the cavity 61 is respectively fixedly connected with a battery pack 610, an alarm 611, a positive electrode sheet 612, and a negative electrode sheet 613. The positive electrode sheet 612 and the negative electrode sheet 613 are located on the inner walls on the left and right sides of the cavity 61. A limiting groove 65 is provided at the bottom of the inner cavity of the cavity 61. The inner wall of the cavity 61 is fixedly connected with a spring 66, and the other end of the spring 66 is fixedly connected with a moving block 67. The bottom end of the moving block 67 is slidably connected to the inner wall of the cavity 61 through a limit groove 65. The moving block 67 is fixedly embedded with an iron block 68 and a strong magnetic second 69 on the side away from the spring 66. The strong magnetic first 63 is fixedly embedded on the outer walls of the left and right ends of the curtain foot 4. By embedding the strong magnetic first 63 at the two ends of the curtain foot 4, the strong magnetic first 63 and the strong magnetic second 69 are moved only when the curtain foot 4 is in contact with the ground. The two guide pieces 64 are repelled, so that the repulsive magnetic force squeezes the moving block 67, thereby driving the spring 66 to compress, and the iron block 68 will be away from the second guide piece 64. The second guide piece 64 is fixedly embedded on the outer wall of the door frame 1, and the back of the second guide piece 64 is located in the cavity 61. The bottom end of the second guide piece 64 is flush with the bottom of the cavity 61. The bottom end of the second guide piece 64 is flush with the bottom of the cavity 61, so that the moving block 67, without the action of the repulsive magnetic force and under the action of the elastic force of the spring 66, drives the iron block 68 to contact with the second guide piece 64;

[0043] The positive electrode 612, the alarm 611, the battery pack 610, and the iron block 68 are connected in sequence through lines, and the negative electrode 613 is connected to the guide piece 2 64 through lines. By connecting the positive electrode 612, the alarm 611, the battery pack 610, and the iron block 68 in series, and the negative electrode 613 is connected to the guide piece 2 64 in series, and then combined with the guide piece 1 62 and the repulsive effect of the strong magnet 1 63 on the strong magnet 2 69, under the elastic force of the spring 66, the moving block 67 is pushed to move toward the guide piece 2 64, so that the iron block 68 contacts the guide piece 2 64, so that the entire circuit forms a path, and the alarm sounds, thereby achieving the effect of anti-pry sensing, and giving an early warning of prying, with higher safety.

[0044] Working principle: The key is inserted into the lock body 3 and rotated, thereby driving the round rod 57 to rotate, and the round rod 57 will drive the rotating block 52 to rotate, or the rotating block 52 is driven to rotate by rotating the handle 55, and the rotation of the rotating block 52 will drive the rotating rod 53 to deflect, thereby driving the bolt rod 54 to move left and right, and then the bolt rod 54 is inserted into or pulled out of the through-port 614 to lock or unlock the rolling door 2. When the bolt rod 54 is inserted into the through-port 614, the through-port 614 will strongly hinder the bolt rod 54 from moving upward, thereby preventing the rolling door 2 from moving upward, so that the rolling door 2 cannot be pried by human power, and the purpose of anti-prying is achieved;

[0045] When the rolling door is closed, the bolt rod 54 is inserted into the opening 614, and the guide piece 1 62 connects the positive electrode piece 612 with the negative electrode piece 613. Through the strong magnet 1 63 embedded at both ends of the curtain foot 4, only when the curtain foot 4 contacts the ground, the strong magnet 1 63 and the strong magnet 2 69 repel each other, so that the repulsive magnetic force squeezes the moving block 67, thereby driving the spring 66 to compress, and the iron block 68 will move away from the guide piece 2 64. When the rolling door 2 is pried, the curtain foot 4 moves upward, and the strong magnet 2 69, without being affected by the strong magnet 1 63, drives the iron block 68 to contact the guide piece 2 64 under the elastic force of the spring 66, so that the entire circuit in the sensing mechanism 6 forms a path, and the alarm sounds, thereby achieving the effect of anti-pry sensing, and giving an early warning of prying, with higher safety.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
