In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.
[0024] like Figure 1-6 It is a structural schematic diagram of a connection structure of the front and rear panels of a door body in a preferred embodiment of the utility model. In this embodiment, a connection structure of the front and rear panels of a door body includes a front panel 1 and a rear panel 2. A fixed plate 3 is fixedly connected at the upper and lower ends of one end surface of the front panel 1, and a first limit plate 4 is fixedly connected between the two fixed plates 3 at one end surface of the front panel 1, a connecting plate 5 is fixedly connected at a position of the rear panel 2 relative to the fixed plate 3, and a second limit plate 6 is fixedly connected at a position of the rear panel 2 relative to the first limit plate 4. The connecting plate 5 is movably connected to the inner side of the fixed plate 3, and the second limit plate 6 is movably connected to the inner side of the first limit plate 4, so that the distance between the front panel 1 and the rear panel 2 has an adjustable function, which effectively solves the problems raised in the background technology.
[0025] In this embodiment, a connecting groove 31 is provided inside the fixing plate 3 , a connecting plate 5 is movably connected in the connecting groove 31 , a rotating hole 32 is provided in the connecting groove 31 , and an adjusting mechanism 9 is connected by rotating in the rotating hole 32 .
[0026] In this embodiment, the adjustment mechanism 9 includes an adjustment block 91 and an adjustment torsion spring 92. The adjustment torsion spring 92 is fixedly connected to one end of the adjustment block 91. The adjustment torsion spring 92 is rotatably connected to the outer wall of the fixed plate 3, and the adjustment block 91 is rotatably connected to the inner wall surface of the connecting groove 31. This structural design has the function of driving the adjustment block 91 to rotate by rotating the adjustment torsion spring 92 on the outer wall of the fixed plate 3.
[0027] In this embodiment, a plurality of serrated blocks 8 are provided on the top surface of the connecting plate 5, and the surface of the serrated block 8 is in contact with the surface of the adjustment block 91. The design of this structure can realize the locking and fixing function of the distance between the front plate 1 and the rear plate 2 after adjustment, and effectively prevent the distance between the front plate 1 and the rear plate 2 from changing.
[0028] In this embodiment, the inner wall of the first limiting plate 4 is fixedly connected to the limiting block 41 , and the surface of the second limiting plate 6 is provided with a limiting groove 7 .
[0029] In this embodiment, the limiting block 41 is movably connected in the limiting groove 7 to play a limiting role, thereby effectively preventing the problem of position deviation during the process of adjusting the distance between the front plate 1 and the rear plate 2.
[0030] How it works
[0031] During specific use, it is necessary to adjust the distance between the front plate 1 and the rear plate 2. Use a tool to rotate the adjusting torsion spring 92 so that the adjusting block 91 contacts and separates from the serrated block 8. Pull one of the front plate 1 or the rear plate 2 until the appropriate distance is adjusted. Use a tool to rotate the adjusting torsion spring 92 so that the adjusting block 91 contacts and separates from the serrated block 8 to achieve a locked state, thereby completing the distance adjustment work between the front plate 1 and the rear plate 2.
