Description

Technical Field

[0001] This utility model relates to the field of display screen support and fixing technology, and in particular to a support and fixing structure for multi-screen displays. Background Art

[0002] A display screen is a computer's I / O device, or input / output device. It is a tool for displaying electronic documents through specific transmission equipment onto a screen and then reflecting them to the human eye. When multiple displays are installed, a supporting and fixing structure is required.

[0003] A search revealed that patent CN117570328A discloses a multi-screen display support and fixing structure, belonging to the field of display screen brackets. It includes a base, with a lifting platform slidably connected to the upper side of the base. A secondary screen (sub-screen 1), a secondary screen (sub-screen 2), and a main screen are mounted on the upper side of the lifting platform. The primary screen is positioned to the left of the main screen, and the secondary screen (sub-screen 2) to the right. A height adjustment mechanism and a secondary screen adjustment mechanism are provided between the base and the lifting platform. The height adjustment mechanism is located above the secondary screen adjustment mechanism. Fixing mechanisms are provided on the rear sides of the primary screen, the secondary screen (sub-screen 1), and the main screen, with universal joint mechanisms inside. This solution utilizes a unidirectional drive mechanism and a secondary screen adjustment mechanism. The output shaft of a single-axis motor drives a rotating shaft to rotate in reverse, and under the action of the unidirectional drive mechanism, it transmits power to the secondary screen adjustment mechanism, synchronously adjusting the primary and secondary screens. This allows for synchronized and coordinated adjustment of the secondary and secondary screens, eliminating the need for manual adjustment by the user and improving the user experience.

[0004] The technical solution has the following problems:

[0005] Although the angles of the secondary screens 1 and 2 can be adjusted to synchronously and coordinately tilt towards the main screen, the vertical angles of the main screen, secondary screens 1 and 2 cannot be adjusted during use, making it inconvenient for users to view the screen from a suitable angle. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, which, although the angles of the secondary screens (one and two) can be adjusted synchronously and in coordination towards the main screen, cannot be adjusted when the vertical angles of the main screen, secondary screens one and two need to be adjusted during use, making it inconvenient for users to view the screen from a suitable angle. Therefore, this invention proposes a support and fixing structure for multi-screen displays.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-screen display support and fixing structure includes multiple display screens for display, a base, and a lifting platform. The base is concave, and the outer side of the lifting platform is slidably connected to the inner wall of the base. Three connecting plates are fixedly installed on the top of the lifting platform, and mounting plates are fixedly installed on one side of each of the three display screens. A motor is fixedly installed on the bottom inner wall of the base, and a lead screw is fixedly installed on the output shaft of the motor. A circular hole is opened at the bottom of the lifting platform, and the other end of the lead screw is located in the circular hole. A frame is installed on the lead screw, and both ends of the frame are fixedly connected to the bottom of the lifting platform. A lead screw nut is embedded in one side of the frame, and the lead screw nut is threadedly connected to the lead screw.

[0009] An adjustment mechanism, mounted on the connecting plate, is used to adjust the vertical angle of the display screen.

[0010] The fixing mechanism is installed on the adjustment mechanism to fix the display screen.

[0011] In one possible design, the adjusting mechanism includes a hinge seat, a large rotating rod, a first short plate, a second short plate, a worm, a worm wheel, and a fixed plate. One side of the hinge seat is fixedly connected to one side of the connecting plate. Both ends of the large rotating rod are rotatably connected to the inner walls of both sides of the hinge seat. A bearing is embedded in one side of the hinge seat, and a small rotating rod is fixedly installed on the inner wall of the inner ring of the bearing. One end of the small rotating rod is fixedly connected to one end of the large rotating rod. One side of the first short plate and one side of the second short plate are both fixedly connected to one side of the hinge seat. One end of the worm is rotatably connected to one side of the second short plate, and the other end of the worm passes through one side of the first short plate. A knob for facilitating the rotation of the worm is fixedly installed at the other end of the worm. The worm wheel is fixedly sleeved on the small rotating rod, and the worm meshes with the worm wheel. One side of the fixed plate is fixedly connected to one side of the large rotating rod.

[0012] In one possible design, the fixing mechanism includes a mounting bracket and a bolt. One side of the mounting bracket is fixedly connected to one side of the fixing plate. The mounting bracket has a slot, and the mounting plate is inserted into the slot. The bolt is threadedly connected to the mounting bracket. One side of the mounting plate has a round hole, and one end of the bolt is inserted into the round hole.

[0013] In one possible design, a groove is provided on one side of the lifting platform, and two first sliding grooves are provided on the bottom inner wall of the groove. Sliding strips are slidably connected to the inner wall of the first sliding grooves. The same drawer for storage is fixedly installed on the top of the two sliding strips. An iron sheet is fixedly installed on one side of the drawer, and a magnet is fixedly installed on the inner wall of one side of the groove.

[0014] In one possible design, a ventilation hole is provided on one side of the base to facilitate ventilation for the motor.

[0015] In one possible design, the inner walls on both sides of the base are provided with sliding grooves, and the two sides of the lifting platform are fixedly provided with sliders, one side of which is slidably connected to the inner wall of the sliding groove.

[0016] In this application, during use, the mounting plates on the back of the three displays are sequentially inserted into the three mounting brackets. Then, the bolts are rotated so that one end of the bolt is inserted into the mounting hole of the mounting plate, thus securing the displays. To begin use, the knob is turned by hand. The rotation of the knob drives the worm gear, which in turn drives the worm wheel. The worm wheel, in turn, drives the small rotating rod, which in turn drives the large rotating rod. The large rotating rod, in turn, drives the fixing plate, the mounting bracket, and the displays on the mounting plate to rotate, thereby adjusting the vertical angle of the displays for optimal viewing. The system utilizes the self-locking principle of the worm gear and worm wheel to prevent the large rotating rod from rotating. Starting the motor causes the output of the motor to rotate the lead screw, which in turn moves the frame. This movement of the frame then moves the lifting platform, which in turn moves the display screen on the connecting plate for height adjustment. Drawers are included for storage and organization. The drawers are magnetically secured by magnets and iron plates to prevent them from slipping out of their recesses. The display screen is existing technology; its working principle will not be elaborated here, but can be purchased according to actual needs.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the multi-screen display support and fixing structure uses an adjustment mechanism. The rotation of the knob drives the rotation of the worm gear, which in turn drives the rotation of the worm wheel. The rotation of the worm wheel drives the rotation of the small rotating rod, which in turn drives the rotation of the large rotating rod. The rotation of the large rotating rod drives the rotation of the fixing plate, the mounting bracket, and the display screen on the mounting plate. This allows the vertical angle of the display screen to be adjusted for viewing at a suitable angle.

[0019] In this utility model, the multi-screen display support and fixing structure uses a fixing mechanism to insert the mounting plates on the rear sides of the three displays into the three mounting brackets respectively. Then, the bolts are rotated so that one end of the bolt is inserted into the mounting hole of the mounting plate, thereby fixing the displays.

[0020] In this invention, the vertical angle of the display screen can be adjusted by the adjustment mechanism to facilitate viewing at a suitable angle, and the display screen can be installed and fixed by the fixing mechanism. Attached Figure Description
