Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] See also Figure 1-6 A lifting waterproof box includes a box body 1 and a mounting frame 2 located inside the box body 1.

[0025] The bottom of the box body 1 is open, and the box body 1 includes an outer shell 101 and an inner support frame 102 located inside the outer shell 101.

[0026] The inner support frame 102 is rectangular in shape as a whole, and includes a top frame 103, a bottom frame 104, and a plurality of support columns 105 connected between the top frame 103 and the bottom frame 104. The top frame 103 and the bottom frame 104 are both rectangular frames welded by four angle steels, and the support columns 105 are connected at the four corners of the top frame 103 and the bottom frame 104.

[0027] At the same time, a plurality of connecting columns 106 are connected between the rear sides of the top frame 103 and the bottom frame 104. The connecting columns 106 are provided with a plurality of through holes. The connecting columns 106 are mainly used to install the box body 1 on the wall through expansion screws. The connecting columns 106 pass through the outer shell 101 and are sealed at the connection with the outer shell 101.

[0028] Two mounting plates 107 are also horizontally arranged on the inner sides of the top frame 103 and the bottom frame 104, and an optical axis 108 is fixedly connected between the mounting plates 107 of the top frame 103 and the mounting plates 107 of the bottom frame 104; a linear bearing 109 is slidably connected to the optical axis 108; at the same time, a set of trapezoidal screw mechanisms 4 are also arranged on the right side inside the inner support frame 102; the trapezoidal screw mechanism 4 includes a trapezoidal screw rod 401 and a screw rod nut 402, and the upper and lower ends of the trapezoidal screw rod 401 are rotatably connected to the mounting plate 107 through a bearing seat, and the top of the trapezoidal screw rod 401 passes through the mounting plate 107 and is transmission-connected to the output shaft of the stepper motor 403, and the stepper motor 403 is fixedly mounted on the top of the mounting plate 107;

[0029] At the same time, a space for installing a stepper motor 403 is provided on the top right side of the housing 101;

[0030] A window 3 is installed at the front end of the housing 101. The window 3 is made of transparent glass. The window 3 corresponds to the position of the mounting frame 2 when it is raised, and is used to protect the LED display screen installed in the mounting frame 2 and enable people to see the LED display screen.

[0031] The installation frame 2 is a vertically arranged rectangular frame, and a cross-shaped reinforcing rib plate 201 is fixedly connected to the inner side of the installation frame 2. The reinforcing rib plate 201 divides the installation frame 2 into four installation slots 202 for installing the LED display screen. The installation slots 201 are 2*2, and there are 4 in total, that is, 4 display screens are to be installed;

[0032] At the same time, the left and right sides of the top of the installation frame 2 are also connected upwardly with transition connecting plates 203, and the outer side of the transition connecting plate 203 is connected to at least two bearing mounting plates 204, and each bearing mounting plate 204 is installed with a linear bearing 109;

[0033] At the same time, the outer side of the bearing mounting plate 204 at the lower right side of the mounting frame 2 is extended outward, and the lead screw nut 402 of the trapezoidal lead screw mechanism 4 is fixedly mounted on the extended part;

[0034] At the same time, the bottom of the installation frame 2 is also fixedly connected with a lower end cover 205. When the lower end cover 206 is raised, the lower end cover 206 can be completely located in the bottom frame 104 composed of angle steels;

[0035] When the utility model is used, the stepper motor 403 drives the trapezoidal lead screw 401 of the trapezoidal lead screw mechanism 4 to rotate, and the trapezoidal lead screw 401 drives the installation frame 2 to rise along the optical axis through the lead screw nut, and then the installation frame 2 is raised. When it rises to the right position, the lower end cover 206 of the installation frame 2 can completely close the box body 1; when maintenance is needed, the stepper motor 403 is reversed, which can drive the installation frame 2 to descend, and the LED display screen installed on the installation frame 2 can be repaired;

[0036] The trapezoidal lead screw itself can realize self-locking, that is, when the stepper motor 403 is powered off, the installation frame 2 can remain in a high position and will not fall. When the installation frame 2 needs to be lowered for maintenance, the stepper motor 403 can be started to drive the installation frame 2 to fall;

[0037] Of course, if the installation frame 2 drops during actual use, an electromagnetic brake (existing technology, not shown in the figure) can be installed on the output shaft of the stepper motor 403;

[0038] This solution uses a box 1 with a closed top and sides to prevent rainwater from entering the interior of the box 1; the sides and top of the box 1 are in a state that they will not be opened after installation, and the only opening is located at the bottom of the box 1, so rainwater cannot overcome gravity and enter the interior of the box.
