Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The embodiments of this application are described below with reference to the accompanying drawings: refer to Figures 1 to 6 According to an embodiment of this application, a display bracket includes: a column 130; a connecting arm, one end of which is connected to the column 130, and the other end of which is used for connecting to industrial equipment; a sleeve 210, which is rotatably fitted onto the column 130, and the sleeve 210 is connected to a base plate 140, which is used to mount a display 2; a first washer 220 is provided between the sleeve 210 and the column 130, the first washer 220 being made of an elastic material and having an opening in the circumferential direction; a first tension adjusting member 230 is provided on the sleeve 210, which can press and release the first washer 220; when the first tension adjusting member 230 presses the first washer 220, the opening of the first washer 220 will shrink, thus fixing the sleeve 210 and the first washer 220 onto the column 130.

[0025] like Figure 1 As shown, the connecting arm includes a first horizontal plate 110 and a second horizontal plate 120. The first horizontal plate 110 is connected to the base plate 1 fixed on the equipment. One end of the second horizontal plate 120 is hinged to the first horizontal plate 110, and the column 130 is vertically inserted at the end of the second horizontal plate 120 away from the first horizontal plate 110.

[0026] like Figure 1 , Figure 3 and Figure 6 As shown, the rear end of the first horizontal plate 110 is connected to the substrate 1, and is fixedly mounted to the processing equipment in the industrial environment via the substrate 1. A second horizontal plate 120 is hinged to the front end of the first horizontal plate 110, and the second horizontal plate 120 can swing relative to the first horizontal plate 110. A column 130 is vertically positioned at the front end of the second horizontal plate 120. The column 130 is cylindrical, and a sleeve 210 is fitted onto the column 130. The sleeve 210 is approximately hollow and can move up and down along the column 130 and rotate around the column 130. A base plate 140 is connected to the front end of the column 130, and the base plate 140 is used to mate with the back of the display 2 to complete the installation and fixation of the display 2. By swinging the second horizontal plate 120 relative to the first horizontal plate 110, and by moving the sleeve 210 up and down and rotating it relative to the column 130, the position of the display 2 relative to the processing equipment can be adjusted. A first washer 220 is provided in the annular gap between the inner wall of the sleeve 210 and the outer wall of the column 130. The first washer 220 has an opening in the circumferential direction, which is set to provide a margin for the contraction of the first washer 220. First tensioning members are provided at the left and right ends of the sleeve 210. When the position of the display 2 is adjusted and it is necessary to fix the display 2, the first tensioning member moves towards the column 130. The first tensioning member presses the first washer 220, causing the opening of the first washer 220 to contract. The first washer 220 is tightly attached to the surface of the column 130, thereby fixing both the sleeve 210 and the first washer 220 to the column 130. At this time, the sleeve 210 can no longer slide up and down or rotate relative to the column 130. When the position of the display 2 needs to be adjusted again, the first tensioning member moves away from the column 130, and the first tensioning member no longer presses the first washer 220. After the first washer 220 is released, the opening expands and it is no longer tightly attached to the surface of the column 130. At this time, the sleeve 210 can move up and down and rotate relative to the column 130, which makes it easier for the operator to adjust the position and orientation of the display 2.

[0027] By fastening the sleeve 210 to the column 130 with the first tension adjustment component 230 and the first washer 220, this monitor bracket can withstand high-intensity vibrations on high-speed moving equipment without loosening. While enabling the monitor bracket to adjust the position of the monitor 2, it also prevents the monitor bracket from loosening during high-speed operation, reducing the risk of the monitor 2 falling. Furthermore, the first washer 220 effectively reduces frictional damage to the column 130 caused by rotating the sleeve 210 when adjusting the position of the monitor 2.

[0028] Thus, the display bracket is connected to the equipment base plate 1 via the first horizontal plate 110, the second horizontal plate 120 is hinged to the first horizontal plate 110, the column 130 passes through the end of the second horizontal plate 120, and the sleeve 210 is fitted onto the column 130 and connected to the base plate 140, realizing multi-degree-of-freedom adjustment of the display 2 in height, angle, and direction. An elastic first washer 220 with an opening is provided between the sleeve 210 and the column 130, and its tightening or loosening is controlled by the first tension adjustment member 230. When the first tension adjustment member 230 tightens the first washer 220, the washer opening contracts, tightly gripping the column 130, thereby firmly fixing the sleeve 210 and effectively preventing the sleeve 210 from loosening or sliding under high-speed movement or high-intensity vibration environments. This structure not only improves the stability and load-bearing capacity of the bracket but also simplifies the adjustment operation, enabling the display 2 to maintain a stable position in industrial vibration environments and reducing the risk of the display 2 falling off due to vibration. Meanwhile, the elastic design of the first washer 220 reduces direct friction between metal parts during adjustment, extends the service life of the bracket, and is suitable for heavy-duty industrial scenarios.

[0029] like Figures 4 to 6 As shown, the monitor bracket also includes a first fixing ring 310, which is sleeved on the column 130 and located below the sleeve 210. A second washer 320 is provided between the first fixing ring 310 and the column 130. The second washer 320 is made of elastic material and has an opening in the circumferential direction. A second tension adjusting member 330 is provided on the first fixing ring 310. The second tension adjusting member 330 can tighten and release the second washer 320. When the second tension adjusting member 330 tightens the second washer 320, the opening of the second washer 320 will shrink, thus fixing the first fixing ring 310 and the second washer 320 to the column 130.

[0030] When adjusting the orientation angle of the monitor 2, the pressure of the first tension adjustment component 230 on the first washer 220 needs to be loosened. However, the loosening of the first washer 220 will cause the sleeve 210 to lose its constraint along the axis of the column 130. Under the weight of the monitor 2 and the sleeve 210 itself, the sleeve 210 may easily slide down the column 130, causing inconvenience in adjusting the monitor 2's angle. Improper operation may even damage the monitor stand and the monitor 2. Therefore, an independent first fixing ring 310 is separately installed below the sleeve 210 and fixed to the column 130. When the first fixing ring 310 is installed, when adjusting the display angle, while maintaining the pressure of the second tension adjusting member 330 on the second washer 320, the pressure of the first tension adjusting member 330 on the first washer 220 is released. At this time, although the sleeve 210 loses its fixation to the column 130, the first fixing ring 310 below it remains fixed on the column 130. Therefore, the first fixing ring 310 can support the sleeve 210, preventing the sleeve 210 from sliding down, allowing the sleeve 210 to easily rotate around the column 130 to adjust the angle of the display 2. When it is necessary to adjust the vertical position of the display 2, the pressure of the second tension adjusting member 330 on the second washer 320 can be released, allowing the first fixing ring 310 to move up and down. After the first fixing ring 310 moves to the desired position, the second tension adjusting member 330 is used to tighten the second washer 320 again to complete the fixation of the first fixing ring 310. Therefore, by setting the first fixing ring 310, on the one hand, the fixing of the sleeve 210 along the vertical direction of the column 130 can be further strengthened, and on the other hand, the sleeve 210 can be provided with vertical support when adjusting the rotation angle of the display 2, which simplifies the operation of adjusting the display 2 and improves the convenience and safety of adjusting the angle of the display 2.

[0031] The first fixing ring 310 is located below the sleeve 210. The second tension adjustment element 330 controls the contraction and release of the second washer 320, achieving independent fixation of the first fixing ring 310 on the column 130. When the first washer 220 of the sleeve 210 is loosened to adjust the angle, the first fixing ring 310 still provides vertical support, preventing the sleeve 210 from sliding down due to the weight of the display 2, thus avoiding loss of control of the bracket or collision of the display 2 with the equipment during adjustment. Furthermore, the first fixing ring 310 also serves as a lower limit device for the sleeve 210, further enhancing the bracket's vertical vibration resistance, making the display 2 more stable and safer during height and angle adjustments, and improving operational convenience and reliability.

[0032] like Figures 4 to 6As shown, it also includes a second fixing ring 410, which is sleeved on the column 130 and located above the sleeve 210. A third washer 420 is provided between the second fixing ring 410 and the column 130. The third washer 420 is made of elastic material and has an opening in the circumferential direction. A third tension adjusting member 430 is provided on the second fixing ring 410. The third tension adjusting member 430 can tighten and release the third washer 420. When the third tension adjusting member 430 tightens the third washer 420, it will cause the opening of the third washer 420 to shrink, thus fixing the second fixing ring 410 and the third washer 420 to the column 130.

[0033] In this embodiment, the sleeve 210 is clamped between the first fixing ring 310 and the second fixing ring 410. The first tension adjusting member 230, in conjunction with the first washer 220, controls the movement and fixation of the display 2 in the rotational direction around the column 130. The second tension adjusting member 330, the second washer 320, the third tension adjusting member 430, and the third washer 420 control the movement and fixation of the display 2 in the axial direction along the column 130. When it is necessary to adjust the rotation angle of the display 2, the second washer 320 and the third washer 420 are kept locked, and the first washer 220 is released. At this time, the sleeve 210 cannot move up and down under the limitation of the first fixing ring 310 and the second fixing ring 410, but it can rotate around the column 130 to adjust the angle of the display 2. When the vertical position of the display 2 needs to be adjusted, the locking of the first washer 220, the second washer 320, and the third washer 420 is released. The sleeve 210, the first fixing ring 310, and the second fixing ring 410 are then moved up and down synchronously to the desired position before the first washer 220, the second washer 320, and the third washer 420 are tightened again. By setting the first fixing ring 310 and the second fixing ring 410 to clamp the sleeve 210, the fixation of the sleeve 210 along the vertical direction of the column 130 can be further strengthened, preventing the vibrating display bracket from loosening during the operation of the processing equipment.

[0034] A second fixing ring 410, a third washer 420, and a third tension adjusting component 430 are added to form a structure in which the sleeve 210 is held between the upper and lower fixing rings. The second fixing ring 410 is located above the sleeve 210 and is fixed by the third washer 420 and the third tension adjusting component 430. This double fixing ring design makes the axial positioning of the sleeve 210 on the column 130 more secure, especially when the equipment generates continuous vibration during operation, it can effectively suppress the vertical movement of the sleeve 210. When it is necessary to adjust the height of the display 2, the position of the sleeve 210 and the two fixing rings can be adjusted simultaneously and then re-locked to ensure the stability of the overall structure. This structure not only enhances the vibration resistance of the bracket but also improves the accuracy of adjustment and the reliability of repeatability, making it suitable for industrial environments with extremely high stability requirements.

[0035] like Figures 4 to 6 As shown, the first tension adjustment element 230 is a threaded knob, which passes radially through the sleeve 210. By turning the threaded knob, it moves towards and away from the first washer 220, thereby tightening and releasing the first washer 220. The sleeve 210 has a threaded hole, and the threaded knob is disposed in the threaded hole. Turning the threaded knob allows its end to move closer to and away from the column 130, thereby tightening and releasing the first washer 220. When the threaded knob is turned so that it is close to the column 130, its end presses against the first washer 220, fixing the sleeve 210 and the first washer 220 to the column 130. When the threaded knob is turned in the opposite direction so that it is away from the column 130, its end moves away from the first washer 220, allowing the sleeve 210 and the first washer 220 to move freely relative to the column 130. The second tension adjustment component 330 and the third tension adjustment component 430 can also be set as threaded knobs. The principle of pressing and releasing the second washer 320 and the third washer 420 is the same as the principle of pressing and releasing the first washer 220 by the first tension adjustment component 230, and will not be described again.

[0036] Radial movement is achieved through a threaded engagement, thereby tightening or releasing the first washer 220. The threaded knob has a simple structure and intuitive operation; users can quickly tighten or loosen it by simply turning the knob, without the need for special tools, thus improving the convenience of on-site operation. The threaded drive has a self-locking characteristic, maintaining a locked state even under vibration, preventing loosening due to equipment operation. Furthermore, the threaded knob's manufacturing process is mature and inexpensive, facilitating mass production and maintenance, enhancing the economic efficiency and practicality of the monitor bracket.

[0037] like Figure 4 and Figure 6 As shown, the lower end of the first washer 220 extends radially outward along the column 130 to form a first convex ring 221. The outer diameter of the first convex ring 221 is larger than the inner diameter of the sleeve 210, and the first convex ring 221 is located below the bottom surface of the sleeve 210. During the assembly of this monitor bracket, when assembling the sleeve 210, the upper end face of the first convex ring 221 abuts against the lower end face of the sleeve 210, ensuring that the first washer 220 is aligned with the sleeve 210, thus improving the ease of assembly of the monitor bracket. Ensuring that the first washer 220 is correctly installed inside the sleeve 210 prevents misalignment or detachment of the washer, improving production efficiency and assembly accuracy. The first convex ring 221 also increases the contact area with the sleeve 210 when the washer is under pressure, improving stress distribution, reducing local stress concentration, and extending the service life of the washer and the sleeve 210. Simultaneously, the convex ring structure helps maintain the stability of the washer under vibration, further improving locking reliability.

[0038] like Figure 4 and Figure 6As shown, the upper end of the second washer 320 extends radially outward along the column 130 to form a second convex ring 321, which is located between the sleeve 210 and the first fixing ring 310. The lower end of the third washer 420 extends radially outward along the column 130 to form a third convex ring 421, which is located between the sleeve 210 and the second fixing ring 410. When the sleeve 210 rotates relative to the first fixing ring 310 and the second fixing ring 410, the second convex ring 321 and the third convex ring 421 can respectively prevent the sleeve 210 from rubbing against the support between the first fixing ring 310 and the second fixing ring 410, thus preventing frictional wear on the display support when adjusting the rotation of the display 2.

[0039] The second washer 320 and the third washer 420 are respectively provided with a second convex ring 321 and a third convex ring 421, located between the sleeve 210 and the fixed ring. These convex rings play a role in isolation and buffering when the sleeve 210 rotates, preventing the sleeve 210 from directly contacting the fixed ring, reducing friction and wear between metals, and protecting the surface of the bracket from scratches. The convex ring structure can also absorb some impact energy in a vibration environment, enhancing the overall vibration resistance and extending the service life of the bracket. In addition, the presence of the convex rings allows the washers to transmit force more evenly when compressed, improving the stability and consistency of locking.

[0040] like Figure 1 and Figure 2As shown, a keyboard tray structure 150 is connected to the lower end of the base plate 140 via a connecting plate 141. The keyboard tray structure 150 is horizontally oriented, with side reinforcing ribs 142 on both sides of the connecting plate 141. The keyboard tray structure 150 has upward-facing keyboard tray flanges 151 on its periphery and a front reinforcing rib 152 at its front end. The keyboard tray structure 150, connected to the lower end of the base plate 140 via the connecting plate 141, expands the functionality of the support. The keyboard tray structure 150 provides an area for industrial operators to place their keyboards or control panels, allowing for centralized arrangement of human-machine interface devices and optimizing workstation layout. The integrated design of the keyboard tray and monitor 2 reduces the complexity of on-site installation and improves space utilization. This structure is suitable for various industrial scenarios, such as control consoles and workbenches, enhancing the overall integrity and aesthetics of the equipment while increasing practicality. The side reinforcing ribs 142 on both sides of the connecting plate 141 significantly strengthen the connection between the keyboard tray structure 150 and the base plate 140. The side reinforcing ribs 142 effectively resist the bending moments and vibration loads generated during keyboard tray use, preventing deformation or breakage of the connecting plate 141 and improving the rigidity and durability of the overall structure. This design is particularly suitable for heavy-duty or high-frequency industrial environments, ensuring the stability of the keyboard tray under long-term loads and extending the service life of the bracket. Upward-facing keyboard tray flanges 151 are provided around the perimeter of the keyboard tray structure 150, forming a protective structure to prevent keyboards or other items from slipping off the tray. The flange design also enhances the structural rigidity of the keyboard tray, preventing deformation of the tray edges due to load. In vibration environments, the flanges effectively limit item displacement, improving operational safety. Furthermore, the flange structure facilitates cleaning and maintenance, meeting the durability and ease-maintainability requirements of industrial equipment. A front reinforcing rib 152 is provided at the front end of the keyboard tray structure 150, further enhancing the keyboard tray's load-bearing capacity and resistance to deformation. The front reinforcing rib 152 effectively resists sagging or bending at the front end, especially when placing heavy keyboards or equipment, maintaining the tray's horizontal stability. This structure improves the reliability and safety of the keyboard tray, making it suitable for various industrial applications and ensuring structural integrity during long-term use.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
