An embodiment of the present application provides a display screen, as shown in FIG. 1 and FIG. 2 , the display screen includes a display unit and a box body 2 . There are several display units. The box body 2 is provided with several installation areas. Several display units are installed in several installation areas of the box body 2 in a one-to-one correspondence. As shown in FIG. 3 and FIG. 4 , the display unit includes a unit body 1 and a handle 3 . The unit body 1 includes a display surface and a mounting surface. A handle 3 is rotatably connected to the mounting surface of the unit body 1 . The handle 3 includes a grip end 31 and a top end 32 . Each installation area of the box body 2 is provided with a gear lever 4 that matches the position of the handle 3 . After the display unit is installed on the box body 2, when the display unit needs to be disassembled, the grip end 31 of the handle 3 installed on the unit body 1 can be held to rotate the handle 3, and the gear lever on the installation area of the box body 2 4 can block the handle 3 so as to provide a fulcrum for the handle 3, so that the top end 32 of the handle 3 pushes the unit body 1 away from the installation area of the box body 2, that is, the unit body 1 is separated from the installation area of the box body 2. In the display screen of this embodiment, the disassembly of the display unit is assisted by the cooperation between the handle 3 on the unit body 1 and the lever 4 on the installation area of the box body 2, and the handle 3 can be used like a lever when it is rotated. , the lever 4 can be used as a fulcrum of the handle 3 , which can greatly save the force required to hold the handle 3 to release the unit body 1 from the installation area of the box body 2 . In this way, when the unit body 1 is detached from the installation area of the box body 2, the unit body can be detached from the box body 2 more easily and with less effort. In this embodiment, a plurality of first magnetic elements 5 are provided on the installation surface of the unit body 1 . Each installation area of the box body 2 is provided with a plurality of second magnetic attraction parts which are respectively mutually magnetically attracted with a plurality of the first magnetic attraction parts 5 . The display unit is installed and fixed on the box body 2 through the mutual attraction between the first magnetic element 5 and the second magnetic element.

In this embodiment, as shown in FIG. 3 and FIG. 4 , the handle 3 is rotatably connected to the mounting surface of the unit body 1 through the rotating shaft 6 . The rotating shaft 6 is arranged at the top end 32 . Since the rotating shaft 6 is disposed at the top holding end 32 , the power arm between the holding end 31 and the rotating shaft 6 is larger than the resistance arm between the top holding end 32 and the rotating shaft 6 , so that the handle 3 can be held relatively more effortlessly. In this embodiment, the top holding end 32 is an eccentric wheel structure. During the process of turning the handle 3 to push the unit body 1 away from the installation area of the box body 2 , the distance from the outside of the top holding end 32 away from the rotation center gradually increases , the handle 3 is blocked by the lever 4 , and the lower end of the jacking end 32 pushes the unit body 1 away from the installation area of the box body 2 .

In this embodiment, the top holding end 32 is provided with a groove 321 . After the display unit is installed in the box body 2 , as shown in FIG. 2 , one end of the gear lever 4 extends into the groove 321 . When the handle 3 is rotated, the lever 4 blocks the top end 32 . Since the gear lever 4 is located in the groove 321, the groove 321 has a certain limiting effect on the up and down movement of the gear lever 4 along the surface perpendicular to the installation area of the box body 2, which can effectively avoid the wind blowing the display unit up and down Move away from box 2. In this embodiment, as shown in FIGS. 2 to 4 , the top holding end 32 is further provided with a limiting block 322 , and the limiting block 322 is located above the groove 321 . A bump 41 is provided at one end of the gear lever 4 extending into the groove 321 . After the display unit is installed in the installation area of the box body 2, the installation surface of the unit body 1 faces the installation area of the box body 2, and the protruding block 41 can be blocked in front of the limit block 322 away from the box body 2, that is, the protrusion The block 41 is located between the limiting block 322 and the unit body 1 . The protruding block 41 and the limiting block 322 form a limit for each other, so as to further firmly install the unit body 1 in the installation area of the box body 2 . in this way. The limiting block 322 and the bump 41 cooperate to prevent the display unit from detaching from the cabinet 2 , which can limit the wind blowing so that the display unit moves forward in a direction away from the installation area of the cabinet 2 and detaches from the cabinet 2 . When the handle 3 is turned to push the unit body 1 away from the installation area of the box body 2 , the limiting block 322 and the protruding block 41 are spatially staggered for avoidance, so that the protruding block 41 and the limiting block 322 do not restrict each other's movement. , so that the handle 3 can be separated from the box body 2 . In this way, the unit body 1 can be detached from the case 2 . In this embodiment, two bases 7 spaced apart are mounted on the mounting surface of the unit body 1 . The handle 3 is rotatably connected between the two bases 7 through the rotating shaft 6 . In this embodiment, a torsion spring is sleeved on the rotating shaft 6 . When the handle 3 is turned to push the unit body 1 away from the installation area of the box body 2 , the torsion spring is elastically deformed. After the unit body 1 is separated from the installation area of the box body 2, the elastic force of the torsion spring can drive the handle 3 to rotate and reset.

In this embodiment, the holding end 31 is T-shaped, which is convenient for holding. In this embodiment, two handles 3 are symmetrically arranged on the display body 1 of each display unit, and two levers 4 are symmetrically arranged in each installation area. The setting position of the handle 3 corresponds to the setting of the lever 4 .

In this embodiment, a positioning block 8 is further provided on the installation surface of the unit body 1 . The box body 2 is provided with a positioning groove matching with the positioning block 8. The matching of the positioning block 8 with the positioning groove facilitates the alignment of the first magnetic element 5 and the second magnetic element. In other embodiments, the positioning block 8 can also be set on the box body 2 , and the positioning groove can be set on the installation surface of the unit body 1 .

The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features It is considered to be the range described in this specification.

The above-mentioned embodiments only represent several embodiments of the present application, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the appended claims.
