[0029] The present invention is further described in detail below in conjunction with the embodiments.

[0030] Specific embodiment 1 of the anti-theft door with visual function provided by the utility model:

[0031] See also Figure 1-7 The anti-theft door with visual function includes a door body 1; corresponding mounting holes 2 for installing visual components are arranged on the inner and outer walls of the upper part of the door body 1; in this embodiment, the mounting holes 2 on the inner and outer walls of the door body 1 are both circular holes.

[0032] In this embodiment, the visible component is a door mirror 11, which includes an outer cylinder 111 and an inner cylinder 112. The inner cylinder 112 is connected to the outer cylinder 111 by threads and passes through the mounting hole 2. The outer end of the outer cylinder 111 and the inner end of the inner cylinder 112 are both provided with tempered glass mirrors, and the outer side of the outer end of the outer cylinder 111 and the outer side of the inner end of the inner cylinder 112 are both provided with annular limiting flanges. After the outer cylinder 111 and the inner cylinder 112 are threadedly connected, the limiting flanges can be stuck on the inner and outer sides of the door body 1.

[0033] A baffle 3 is provided in the door body 1 for vertical sliding. Specifically, two vertical slide rails 9 are symmetrically provided in the door body 1, and the baffle 3 slides vertically between the two slide rails 9. In this embodiment, the slide rail 9 is connected to the inner side of the inner wall of the door body 1, and the transverse cross-section of the slide rail 9 is L-shaped, so that the slide rail 9 can slide vertically on the inner side of the inner wall of the door body 1. Figure 4 As shown, the lower end of the slide rail 9 is connected to a bottom plate, and the bottom plate forms a lower limit position for the baffle 3 to slide downward.

[0034] The upper part of the baffle 3 is provided with a through hole 4 for the visual component to pass through; in this embodiment, the through hole 4 is a circular hole for the door mirror 11 to pass through. When the door mirror 11 passes through the mounting hole 2 and the through hole 4, the door mirror 11 positions the baffle 3, and the baffle 3 will not fall along the slide rail 9. When the door mirror 11 is removed or damaged, the door mirror 11 will not limit the baffle 3, and the baffle 3 will fall under the action of its own gravity.

[0035] A lock tongue 6 is installed in the middle part of the door body 1, and a lock hole 5 cooperating with the lock tongue 6 is provided at the lower end of the baffle 3; a support plate 10 is provided in the door body 1, and the support plate 10 is connected to the outer side of the lower end of the slide rail 9, and the lock tongue 6 is horizontally slidably penetrated on the support plate 10, and the support plate 10 has a square hole cooperating with the lock tongue 6, and the lock tongue 6 is connected to the side facing away from the baffle 3. The end of the spring 7 abuts against the inner wall of the door body 1. In this embodiment, the spring 7 abuts against the inner side of the outer wall of the door body 1.

[0036] Since the support plate 10 has a certain thickness, the square hole on it can support and guide the sliding of the lock tongue 6. When the door mirror 11 positions the baffle 3, the lock tongue 6 is located at the lower side of the baffle 3. Figure 4 and Figure 5 As shown, an arc surface is provided on the upper side of one end of the lock tongue 6. When the door mirror 11 is removed or damaged by illegal personnel, the baffle 3 falls by its own weight and contacts the arc surface of the lock tongue 6, causing the lock tongue 6 to move horizontally and compress the spring 7, so that the lock tongue 6 is retracted and the baffle 3 continues to fall. When the baffle 3 falls on the upper side of the bottom plate, the lock hole 5 corresponds to the lock tongue 6, and the spring 7 makes the lock tongue 6 extend and extend into the lock hole 5, so as to realize the positioning of the baffle 3 in the lower position. At this time, the perforation 4 does not correspond to the mounting hole 2, and the baffle 3 blocks the mounting holes 2 on the inner and outer walls of the door body 1, so as to avoid using the mounting holes 2 and tools to manipulate the inner handle of the door body 1 to open the door from the outside of the door.

[0037] In this embodiment, a flange is provided on the outer side of one end of the locking tongue 6 close to the spring 7, and the area of ​​the flange is larger than the square hole on the support plate 10, so that the spring 7 cannot make the locking tongue 6 pass through the square hole.

[0038] In order to facilitate the resetting of the baffle 3, a resetting hole 8 is provided on the inner wall of the door body 1, and the lock tongue 6 corresponds to the center of the resetting hole 8; after the baffle 3 is locked in the lower position, the lock tongue 6 can be manually compressed on the inner side of the door body 1 to withdraw from the lock hole 5, and then the baffle 3 can be moved up and the new door mirror 11 can be reinstalled.

[0039] In some embodiments, the outer side of the reset hole 8 can be connected to a sealing plate by bolts to prevent the internal structure of the door body 1 from being exposed, thereby ensuring that the appearance of the door body 1 is beautiful and neat.

[0040] Specific embodiment 2 of the anti-theft door with visual function provided by the utility model:

[0041] The difference between this embodiment and the first embodiment is that in the first embodiment, the door mirror 11 is used as a visual component. In this embodiment, the visual component is an electronic cat's eye 12, see Figure 8 and Fig. 9 The electronic cat's eye 12 includes a display terminal 121 and a camera 123. The display terminal 121 is connected to a plug 122, and the camera 123 is connected to a plug post 124. The display terminal 121 and the camera 123 are respectively connected to the inner wall and the outer wall of the door body 1 by bolts. The mounting hole 2 provided on the inner wall of the door body 1 is a square hole that cooperates with the display terminal 121, rather than a circular hole; the mounting hole 2 on the outer wall of the door body 1 is still a circular hole. The plug post 124 cooperates with the plug 122 to realize the electrical connection between the camera 123 and the display terminal 121. A controller is provided in the display terminal 121 to receive the video picture information collected by the camera 123 and display it through the display screen of the display terminal 121. The video picture display of the electronic cat's eye 12 is a prior art and will not be repeated in this embodiment. In some other embodiments, the electronic cat's eye 12 has an intercom function.
