DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] like Figures 1 to 6 As shown, this embodiment proposes a display device, including a bottom shell 1, a display component 2, a control component 3, a limiting mechanism 4, a driving component 5, a lifting plate 6, a protection box 7, a support column 8 and a protection ceiling 9 installed on the upper end of the support column 8 to protect the display component 2.

[0039] Among them, the square bottom shell 1 with a hollow interior and an open bottom serves as the installation basis, and the bottom end of the bottom shell 1 has a closing opening. The lifting plate 6 moves up and down inside the bottom shell 1 and can only move back and forth between the upper side of the bottom shell 1 and the closing opening. Four evenly distributed first hinge supports 301 are fixedly connected to the top of the bottom shell 1, and four evenly distributed second hinge supports 302 are fixedly connected to the upper side of the lifting plate 6. The first hinge supports 301 and the second hinge supports 302 are distributed obliquely and crosswise. An L-shaped driving bent rod 303 is hinged on the four first hinge supports 301, and a straight connecting rod 304 is hinged on the shorter side of the driving bent rod 303. The second hinge support 302 and the driving bent rod 303 are connected together through the connecting rod 304. As the driving bent rod 303 rotates around the first hinge support 301, the lifting plate 6 can be driven by the connecting rod 304 to move up and down inside the bottom shell 1, thereby realizing the lifting function of the lifting plate 6.

[0040] The longer side of the driving bent rod 303 is connected to the first hinge support 301, and a worm gear 502 is fixedly connected to the inside of the first hinge support 301. The worm gear 502 and the first hinge support 301 are connected to each other in rotation, and the driving bent rod 303 is driven to rotate by the worm gear 502. The middle position of the top of the bottom shell 1 is connected to a worm 501 in rotation. The four worm gears 502 connected to the driving bent rod 303 rotate inside the first hinge support 301, and the worm gears 502 connected to the driving bent rod 303 are meshed with the worm 501. The worm 501 can drive the worm 501. The wheel 502 rotates, and conversely the unidirectional driving characteristic of the worm wheel 502 cannot drive the worm 501 to rotate, so that the driving bent rod 303 can self-lockingly rotate around the first hinge support 301, and perform a self-positioning lifting operation on the lifting plate 6. The worm 501 is controlled and rotated by the servo motor 503 installed on the lower side of the protection box 7. The protection box 7 is fixedly connected to the upper side of the outside of the bottom shell 1, and the battery 10 installed at the front end of the lower side of the protection box 7 is used to power the entire display device.

[0041] When the lifting plate 6 moves upward, the universal wheels 11 installed on the lower side of the lifting plate 6 are retracted into the bottom shell 1, and the outer lower side of the bottom shell 1 contacts the ground, thereby ensuring the contact area between the display device and the ground, increasing the stability of the display device, and ensuring that the display assembly 2 can be displayed stably. When the display device needs to be moved, the lifting plate 6 is moved downward, the universal wheels 11 contact the ground, and the bottom shell 1 is lifted up for easy movement, thereby ensuring stability during use and being convenient and fast when moving.

[0042] In order to ensure that the lifting plate 6 can move up and down smoothly inside the bottom shell 1, limit bars 401 are fixedly connected to the four side walls of the bottom shell 1, and limit grooves 402 used in conjunction with the limit bars 401 are provided around the lifting plate 6. The lifting plate 6 is clamped on the limit bars 401 through the limit grooves 402 to ensure the stability of the lifting plate 6.

[0043] Embodiment 2:

[0044] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0045] In order to increase the display effect of new media influence, the utility model adopts a triangular mounting plate 201, and the mounting plate 201 is fixed on the support column 8 installed on the upper side of the outside of the protective box 7. A display screen is fixedly connected to the upper edge of the mounting plate 201 to increase the display direction so that people from all directions can observe the displayed content and increase the display and publicity effect of new media marketing. A protective ceiling 9 of an umbrella surface is fixedly connected to the upper end of the support column 8 to protect the display screen 202.

[0046] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
