detailed description

The technical solution proposed by the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description and claims, the advantages and features of the utility model will be more clear. It should be noted that all the drawings are in very simplified form and use imprecise ratios, which are only used for the purpose of conveniently and clearly assisting in describing the embodiment of the present utility model.

Example 1

The utility model innovatively fixes the LCD screen and the LCD screen fixing assembly on the car wall as a whole without changing the original LCD screen, see the front schematic diagram of the utility model installed on the elevator car wall in Figure 1, After the utility model is installed, the liquid crystal display screen is arranged facing the car, and can be disassembled and assembled conveniently.

The convenient disassembly and assembly of the liquid crystal screen fixing structure is realized by the connection structure between the liquid crystal screen fixing assembly 1 and the car 2 . The connection structure of the two will now be described in detail with reference to FIGS. 2 to 4 .

The liquid crystal screen fixing assembly 1 includes a panel 4, which is a frame structure matching the shape of the liquid crystal display 3, the liquid crystal display 3 is fixed on the front of the panel 4, and the liquid crystal display 3 can be fixed on the panel 4 by screws 9. Certainly, other fixing forms may also be adopted, which are not specifically limited here.

A first elastic connector 5 is arranged on the back of the panel 4, and the first elastic connector 5 is elastically engaged with the second elastic connector 2 on the back of the car wall 2, so that the front of the panel 4 faces the car, that is, the liquid crystal display 3 Facing the car, it is detachably fixed on the car wall 2. The first elastic connector 4 is usually respectively arranged on the upper and lower ends of the back of the panel 4, and can be fixed on the back of the panel 4 by screws 9; The spacing between the parts 5 is set on the back side of the car wall 2, and the second elastic connecting part 6 can also be fixed on the back side of the car wall 2 by screws. Preferably, the first elastic connecting member 5 and the second elastic connecting member 6 may use reinforcing ribs.

A groove 7 is provided on the clamping surface of the first elastic connector 5 and the second elastic connector 6, and correspondingly, a convex engaging portion 8 is provided on the second elastic connector 6, and the second elastic connector The convex engaging part 8 on the first elastic connecting part 5 cooperates with the groove 7 on the first elastic connecting part 5 , so as to realize the elastic locking between the first elastic connecting part 5 and the second elastic connecting part 6 .
