Specific embodiments

[0028] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0030] As Figures 1-4 shown, this application provides a sealing mechanism for an anti-theft door, including a door frame 1, a door body 2 is rotatably connected to the door frame 1, and a cat's eye 3 is fixedly installed on the door body 2, through which the outside can be observed.

[0031] As Figures 2-4As shown in the figure, a splicing mechanism 4 is provided on the door body 2 and the door frame 1. The splicing mechanism 4 includes rectangular grooves 41 respectively opened on the door frame 1 and the door body 2. Two cross bars 42 and a longitudinal bar 43 are placed inside the rectangular groove 41. Limiting grooves 44 are symmetrically opened at both ends of the cross bar 42. A clamping block 45 is movably clamped inside the limiting groove 44. The clamping block 45 is fixedly connected to the longitudinal bar 43. When installing the cross bar 42 and the longitudinal bar 43, they can be assembled through the limiting groove 44 on the cross bar 42 and the clamping block 45 on the longitudinal bar 43. This setting can facilitate the individual replacement of the cross bar 42 and the longitudinal bar 43 and is convenient for personnel to carry.

[0032] A plurality of screw holes 47 are opened on the surfaces of the cross bar 42 and the longitudinal bar 43. The cross bar 42 and the longitudinal bar 43 are fixed on the rectangular groove 41 of the door frame 1 through fastening bolts 46 arranged in the screw holes 47. The two cross bars 42 and the two longitudinal bars 43 together form a square, and the specification is adapted to the rectangular groove 41. When placing the cross bar 42 and the longitudinal bar 43 inside the rectangular groove 41, the cross bar 42 and the longitudinal bar 43 can be installed on the door body 2 through the fastening bolts 46.

[0033] As Figure 4 shown in the figure, a sealing structure 5 is provided on the splicing mechanism 4. The sealing structure 5 includes a plurality of springs 52 fixedly connected to the cross bar 42 and the longitudinal bar 43. The other ends of the springs 52 are fixedly connected to a sealing rubber strip 51. One side of the sealing rubber strip 51 is fixedly connected to an extension rubber strip 53. The sealing rubber strip 51 can fill the gap between the door frame 1 and the door body 2. At the same time, the extension rubber strip 53 extends from the rectangular groove 41. When the door frame 1 and the door body 2 are closed, the sealing between the door body 2 and the door frame 1 can be realized. Through the cooperation of the sealing rubber strip 51 and the extension rubber strip 53, it can better prevent external factors such as temperature, humidity, and sand and dust from invading the room.

[0034] It should be supplemented and explained that the extension rubber strip 53 is rectangular, and the overall cross section of the extension rubber strip 53 and the sealing rubber strip 51 is in a "cross" shape. The inside of the sealing rubber strip 51 and the extension rubber strip 53 is hollow. At the same time, the cooperation of the spring 52 and the hollow structure can improve the buffering performance when the door body 2 and the door frame 1 collide. The longitudinal length of the sealing rubber strip 51 is equal to the longitudinal length of the rectangular groove 41.

[0035] Furthermore, as Figure 4 shown in the figure, two sound insulation cottons 54 are glued to the inner wall of the sealing rubber strip 51. A plurality of through holes 55 are opened on the sealing rubber strip 51, and the positions of the through holes 55 correspond to the positions of the fastening bolts 46 one by one. The setting of the sound insulation cottons 54 can increase the sound insulation performance of the door body 2. At the same time, the through holes 55 on the sealing rubber strip 51 can facilitate personnel to install the fastening bolts 46 on the cross bar 42 and the longitudinal bar 43.

[0036] Working principle: During actual use, the horizontal bar 42 and the vertical bar 43 are spliced together. Through the through hole 55 on the sealing strip 51, fastening bolts 46 can be screwed into the horizontal bar 42 and the vertical bar 43, thereby realizing the installation of the horizontal bar 42 and the vertical bar 43 on the door body 2, and indirectly realizing the overall installation of the sealing strip 51. The splicing arrangement of the horizontal bar 42 and the vertical bar 43 facilitates the independent replacement of the sealing strip 51 on one side. The fastening bolts 46 can make the sealing strip 51 more firmly fixed on the door body 2, preventing the sealing strip 51 from falling off.

[0037] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
