DETAILED DESCRIPTION
[0020] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4 The utility model provides a technical solution: a double-leaf embedded metal anti-theft door, including a door frame 1, a door panel 2 is attached to the inside of the door frame 1, a shell 3 and a smart door lock 5 are respectively installed on one side of the door panel 2 by screws, and a slide groove 4 is installed on one side of the door frame 1 by screws.
[0022] The outer shell 3 includes a folding plate 302, which is connected to a fixed block 308 through a pin. A rotating shaft 305 is inserted into the inside of the folding plate 302. The lower part of the rotating shaft 305 passes through a gear 304. A rack 303 is meshed on one side of the gear 304. A piston 301 and a moving plate 306 are welded on both sides of the rack 303 respectively. A spring 307 is welded on one side of the moving plate 306.
[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the slide 4 includes a pulley 401, a connecting plate 402 is inserted on one side of the pulley 401, a hydraulic air pump 403 is inserted under the connecting plate 402, and the connecting plate 402 forms a rotating structure through the hydraulic air pump 403, and the external structural dimensions of the pulley 401 are consistent with the internal structural dimensions of the slide 4; when the double-leaf embedded metal anti-theft door is closed, the door frame 1 is easily squeezed and deformed due to excessive closing, thereby damaging the door frame 1. Now, the hydraulic air pump 403 connected to the door panel 2 is improved to rotate the connecting plate 402, and the connecting plate 402 is connected to the pulley 401. The pulley 401 rotates and slides into the inside of the slide 4 for fixation, so as to avoid excessive closing, which may cause damage to the door and play a buffering role, so that the pulley 401 is fixedly stuck in the inside of the slide 4.
[0024] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the rotating shaft 305 forms a rotating structure through the folding plate 302, and the gear 304 forms a rotating structure through the rotating shaft 305; because of the double-leaf embedded metal anti-theft door, forgetting to close the door makes the double-leaf anti-theft door main body unable to prevent theft, now the improved fixed block 308 is fixed above the slide groove 4, the door panel 2 is fixedly connected to the shell 3, the door panel 2 connected to the fixed block 308 through the shell 3 and the door frame 1 connects the folding plate 302, the folding plate 302 rotates the rotating shaft 305, the rotating shaft 305 drives the gear 304 to rotate, the fixed block 308 contains a small motor inside, which can automatically close in place, thereby achieving the effect of rotating the gear 304.
[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the piston 301 forms a sliding structure through the rack 303 and the gear 304; because the door panel 2 of the double-leaf embedded metal anti-theft door is closed quickly, the fitting door frame 1 will be damaged and deformed. Now the improved gear 304 enables the rack 303 to drive the piston 301 to move, achieving a buffering effect, achieving closing and slowing down the closing sound, thereby achieving the effect of the rack 303 driving the piston 301 to move.
[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the movable plate 306 forms an elastic structure through the spring 307; because a loud noise will be generated when the door panel 2 of the double-leaf embedded metal anti-theft door is closed, the movable plate 306 is connected to the spring 307 for buffering to reduce the excessive noise when closing, thereby achieving the effect of moving the movable plate 306 and the piston 301.
[0027] In this embodiment, Figure 1 and Figure 2 As shown, the external structural dimensions of the door panel 2 are consistent with the internal structural dimensions of the door frame 1; because the dimensions of the door panel 2 and the door frame 1 are consistent, it is easy for the door frame 1 to be deformed due to incorrect closing. Now the improved door panel 2 is connected to the outer shell 3 and the slide groove 4 for movement, and the door panel 2 fits with the door frame 1, can be closed tightly, and with the addition of buffering, damage is reduced, thereby achieving the effect of the door panel 2 and the door frame 1 fitting together.
[0028] The use method and advantages of the utility model: When the double-leaf embedded metal anti-theft door is used, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the smart door lock 5 is equipped with password, face and fingerprint unlocking, and the door panel 2 opens and closes on one side of the door frame 1. When closed, the door panel 2 is connected to the hydraulic air pump 403 to make the connecting plate 402 drive the pulley 401 to rotate clockwise, so that the pulley 401 slides into the slide groove 4, and the folding plate 302 makes the rotating shaft 305 inside the shell 3 rotate, and the rotating shaft 305 drives the gear 304 to rotate clockwise, and the gear 304 is meshed with the rack 303, and the rack 303 drives the piston 301, the moving plate 306 and the spring 307 to move to one side in turn.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments.
