[0021] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.
[0022] See also Figure 1 and Figure 2 The utility model provides a double-leaf embedded metal anti-theft door, including a door frame 1, a door panel 2 is arranged in the door frame 1, the door panel 2 is rotatably connected to the door frame 1, the door panel 2 and the door frame 1 are both made of metal materials and adopt an anti-theft door structure, and a reinforcement structure 3 is arranged inside the door frame 1.
[0023] See also Figure 1 、 Figure 3 and Figure 4 The present invention provides a double-leaf embedded metal anti-theft door, including a reinforcement structure 3 including a fixing groove 31. The interior of the front and rear ends of the door frame 1 are both provided with fixing grooves 31. The fixing grooves 31 at the front and rear ends have the same structure. The left and right ends of the inner wall of the fixing groove 31 are both engaged with positioning plates 301. A transverse plate 32 is installed between the positioning plates 301. The transverse plate 32 is located inside the fixing groove 31 and slides along the surface of the positioning plate 301. The positioning plate 301 can position the transverse plate 32 to prevent the transverse plate 32 from shaking left and right. A positioning piece 302 is engaged with the inner wall of 31. The positioning piece 302 is located between the cross plate 32 and the fixing groove 31. The positioning piece 302 is used to position the cross plate 32 to prevent the cross plate 32 from shaking and making abnormal noises during transportation. A pressure pad 33 is assembled inside the fixing groove 31. The pressure pad 33 is in contact with the surface of the cross plate 32. The cross plate 32 is integrally formed with an anti-skid protrusion 34. The top of the anti-skid protrusion 34 is provided with a bevel angle to facilitate the anti-skid protrusion 34 to dock more conveniently. There are six anti-skid protrusions 34, which are evenly laid on the surface of the cross plate 32.
[0024] A locking frame 321 is integrally formed on the surface of the horizontal plate 32. A locking plate 322 is fixed to the inner wall of the fixing groove 31. The inner wall of the locking frame 321 slides along the surface of the locking plate 322. A pressing pad 323 is fixed to the surface of the locking plate 322. The total thickness of the pressing pad 323 and the locking plate 322 is greater than the thickness of the inner width of the locking frame 321. When the locking plate 322 is inserted into the locking frame 321, the pressing pad 323 is squeezed, making the locking frame 321 and the locking plate 322 more stable after insertion.
[0025] When the door frame 1 is fitted on the door opening, the inner wall of the door frame 1 will fit with the surface of the door opening. At this time, the anti-slip protrusion 34 will slide along the surface of the door opening, and the anti-slip protrusion 34 will be pressed to push the cross plate 32. The cross plate 32 will slide along the inner wall of the fixing groove 31 and push the pressure pad 33. The pressure pad 33 is then compressed to produce elastic force, and then pushes the cross plate 32, so that the anti-slip protrusion 34 is tightly stuck on the surface of the door opening. When the anti-slip protrusion 34 is stuck on the surface of the door opening, the friction force will be increased, thereby reinforcing the door. When the door frame 1 is fitted on the surface of the door opening, the door 1 is reinforced and fixed, thereby improving the stability of the fitting.
