[0002] With the increasing improvement of people's living standards and the accelerating pace of life, people's awareness of prevention has also been increasingly strengthened. Therefore, there are various anti-theft doors sold on the market, each with different design concepts, striving to meet the anti-theft requirements of different users.

[0003] Publication No. CN220267536U discloses a structure of an anti-theft door leaf, which can buffer when closing the door to prevent damage to the door leaf due to excessive vibration during the door closing action, improve the service life of the door leaf, and still be able to remain closed after the right-side lock cylinder is damaged, improving the overall safety level. However, during the use process, although the anti-buffering mechanism reduces the wear caused by vibration to a certain extent, in fact, due to the anti-buffering mechanism, it takes a certain amount of time to automatically close when closing the door, and a greater force is required to close the door leaf manually, making it more laborious and time-consuming to close the door. For this reason, we propose a structure of an anti-theft door leaf. Content of the Utility Model

[0011] By adopting the above technical solution, an electrical connection is established with the control box by inserting the electrical connection plug into the electrical through-hole interface on the side wall of the control box.

[0012] Specifically, insulating protective layers and protective coatings are provided on the surfaces of the door leaf frame and the door leaf body.

[0013] By adopting the above technical solution, the insulating protective layer and the protective coating are used to prevent the occurrence of electric shock accidents to users during use.

[0014] Specifically, through-holes for connection that are aligned with and have the same position as the connection plate are provided on the side wall of the positioning plate.

[0025] An electromagnetic layer 8 is fixedly installed on the inner wall of the door frame of the door leaf frame 1, an electrical connection plug 9 is penetrated and fixedly connected to the middle of the connecting plate 4 of the door leaf frame 1, the electrical connection plug 9 is penetrated and inserted into the inside of an electrical through interface 10, and the electrical through interface 10 is opened on the side wall of the control box 7.

[0026] When in use, first, the control box 7 controls the electromagnetic layer 8 on the inner wall of the door leaf frame 1 through an electrical connection method to control it to generate or eliminate magnetic force, so as to ensure that during the closing process, the door leaf body 2 does not directly impact the door leaf frame 1, resulting in damage to the security door and affecting the anti-theft protection effect, and avoiding the influence of the buffering force generated by the traditional buffer mechanism on the closing time, reducing the time required for the user to wait and confirm the closing.

[0027] As shown in the figure, a signal connection panel 11 for conveniently connecting external control devices and power sources is arranged on the top surface of the control box 7.

[0028] When in use, the external control panel and the external power supply are connected through the signal connection panel 11, which is convenient for adjusting the device after installation.

[0029] As shown in the figure, the electromagnetic layer 8 is electrically connected to the control box 7 through the electrical connection plug 9.

[0030] When in use, an electrical connection is established with the control box 7 by inserting the electrical connection plug 9 into the electrical through interface 10 on the side wall of the control box 7.

[0031] As shown in the figure, insulating protective layers and protective coatings are provided on the surfaces of the door leaf frame 1 and the door leaf body 2.

[0032] During use, the insulating protective layer and the protective coating are used to prevent accidental electric shock to users during the use process.

[0033] As shown in the figure, a through connection hole 5 that matches and has the same position as the connection plate 4 is provided on the side wall of the positioning plate 6.

[0034] During use, the control box 7 is connected and fixed to the door leaf frame 1 through the matching through connection hole 5.

[0035] The working principle and usage process of the present utility model: First, pass the fixing member through the through connection hole 5 provided on the surface of the positioning plate 6 and screw it into the positioning gasket, and then install it in the door frame groove pre-opened in the wall. Connect the signal wire and the power wire to the signal connection panel 11 together.
