Description

Technical Field

[0001] The utility model relates to the technical field of display screen installation, in particular to a mobile splicing screen integral supporting device. Background Art

[0002] A spliced ​​display screen is formed by splicing multiple display screens together to form a large display screen. When splicing display screens, a supporting device is required to fix and support the multiple display screens. Most of the existing spliced ​​display screen brackets have a fixed structure and a single function. After the display screen is installed on the bracket, the display screen cannot be adjusted up and down, resulting in the spliced ​​display screen being unable to meet a variety of different viewing needs, resulting in poor practicality.

[0003] The utility model with publication number CN220851351U proposes a splicing support device for splicing screens. Its technical solution records that "according to the width of the display screen, the spacing of a set of mounting mechanisms is first adjusted by moving the limit column upwards and removing the limit column from the limit hole, and then sliding the slide plate on the base. After the slide plate is moved to a suitable position, the limit column is released. Under the action of the spring, the limit column moves into the limit hole at the corresponding position, thereby fixing the slide plate; then, multiple display screens are installed on the screen mounting seat in sequence." In this way, the spacing between multiple slide plates can be adjusted.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. For the spliced ​​display screen, the number of matching slides is relatively large. When adjusting the distance between adjacent slides according to the spliced ​​display screens of different widths, the limit columns need to be operated one by one, which has the defect of time-consuming and labor-intensive spacing adjustment; 2. The above-mentioned prior art does not have a mobile function, which limits the scope of use of the entire spliced ​​screen and has the defect of a small scope of application.

[0005] To this end, the utility model provides a mobile splicing screen integral supporting device. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a mobile splicing screen integral support device, including a support beam 1 and a plurality of vertical poles 2, one side of the vertical pole 2 is provided with a screen mounting plate 3 arranged up and down, the function of the screen mounting plate 3 is to install a single display screen for splicing, the specific installation method is the prior art, and the application will not describe it in detail, after the screen mounting plates 3 on each vertical pole 2 are installed with the display screen, the vertical poles 2 are controlled to be close to each other, so that the plurality of display screens are spliced ​​into a complete screen.

[0023] In the present technical solution, a traveling frame 4 is provided on the outside of the support beam 1. The function of the traveling frame 4 is to enable the device to be easily transferred to another position. The traveling frame 4 and the support beam 1 slide up and down and a lifting drive assembly 5 is provided between the two. The function of the lifting drive assembly 5 is to adjust the height of the support beam 1.

[0024] Specifically, a rectangular frame 41 and a support leg 42 located at the bottom corner of the rectangular frame 41 are fixedly provided on the walking frame 4, a moving wheel 421 is provided at the bottom of the support leg 42, and the moving wheel 421 adopts a guide wheel with a braking function, and a guide column 411 is welded on the top of the rectangular frame 41 near both ends, and the guide column 411 is in a vertical state, and a suspension plate 13 is welded at both ends of the support beam 1, and the suspension plate 13 is Z-shaped, and one end of the suspension plate 13 is welded with a sliding sleeve 131 mounted on the guide column 411, and the support beam 1 can move up and down stably under the guidance of the guide column 411.

[0025] Furthermore, the lifting drive assembly 5 includes an adjusting motor 51 and a transmission screw 52. The bottom of the transmission screw 52 is rotatably connected to the rectangular frame 41 and is screwed through the suspension plate 13. During specific implementation, a thread sleeve mounted on the transmission screw 52 can be welded on the suspension plate 13. When the transmission screw 52 rotates, it can drive the suspension plate 13 to move up and down; wherein, the adjusting motor 51 is fixedly arranged at the bottom of the rectangular frame 41 and its output shaft is fixedly connected to the bottom of the transmission screw 52. The adjusting motor 51 provides driving force for the rotation of the transmission screw 52.

[0026] In this embodiment, the bottom of the vertical pole 2 is fixedly connected with a guide sleeve 21 sleeved on the outside of the support beam 1, and the guide sleeve 21 and the support beam 1 are rollingly matched. In the specific implementation, it is preferred that the upper and lower sides of the support beam 1 are provided with rolling grooves 11, and the upper and lower sides of the guide sleeve 21 are provided with rollers 211 opposite to the rolling grooves 11, and the rollers 211 roll along the rolling grooves 11. This arrangement can improve the smoothness of the horizontal movement of the vertical pole 2 along the support beam 1, and has the advantage of more labor-saving in pushing the vertical pole 2. One side of the support beam 1 is rotatably connected with an eccentric shaft 6, which is parallel to the support beam 1 and located on one side of the guide sleeve 21. The eccentric shaft 6 can squeeze the guide sleeve 21 by using its eccentric characteristics. When the guide sleeve 21 is squeezed, the corresponding vertical pole 2 is locked. When the eccentric shaft 6 no longer squeezes the guide sleeve 21, the vertical plate can be easily moved. This arrangement greatly improves the convenience of adjusting the spacing between all vertical poles 2, thereby improving the efficiency of installing display screens of different widths.

[0027] Specifically, ear plates 12 are welded on one side of the support beam 1 near both ends, and transmission shafts 61 rotatably connected to the ear plates 12 are welded on both ends of the eccentric shaft 6. A control motor 8 is fixedly connected to one side of the support beam 1 and an output shaft is fixedly connected to one end of the transmission shaft 61. The control motor 8 provides driving force for the rotation of the eccentric shaft 6.

[0028] In this embodiment, a resistance-enhancing rubber belt 7 is bonded to the bottom of the rolling groove 11, and the outer wall of the roller 211 is fixedly connected with circumferentially evenly distributed spacers 2111. The purpose of this arrangement is to prevent the roller 211 from rolling freely, that is, the resistance-enhancing rubber belt 7 and the spacers 2111 can enable the roller 211 to stay stably when subjected to a smaller thrust. This arrangement can improve the safety of adjusting the spacing between the vertical poles 2 and avoid collision damage to the horizontally adjacent screen mounting plates 3.

[0029] In this embodiment, a rubber sleeve 9 is provided on the fixed sleeve of the eccentric shaft 6, and a resistance-increasing protrusion 212 is welded on the side of the guide sleeve 21 opposite to the eccentric shaft 6. The purpose of this arrangement is to increase the friction between the guide sleeve 21 and the eccentric shaft 6 and to improve the reliability of the eccentric shaft 6 squeezing and locking the guide sleeve 21.

[0030] When in use, the control motor 8 is started to drive the eccentric shaft 6 to rotate, the guide sleeve 21 and the eccentric shaft 6 are separated, and then each upright pole 2 is pushed to increase the spacing between adjacent upright poles 2, and then each display screen is installed on the screen mounting plate 3. At this time, all the display screens are in a horizontally separated state. At this time, the upright pole 2 is manually pushed, and the roller 211 rolls in the rolling groove 11. The adjacent display screens are in a close and fitting state. Finally, the eccentric shaft 6 is controlled to rotate, and the outer peripheral wall of the eccentric shaft 6 squeezes all the guide sleeves 21 at the same time. At this time, all the upright poles 2 are in a fixed state, and the splicing of the display screen is completed. When the height of the entire screen needs to be adjusted, the adjustment motor 51 is started, and the transmission screw 52 rotates to lift the entire support beam 1, thereby raising the entire screen.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
