Abstract
Description
Technical Field
[0001] This utility model relates to the field of support arm technology, and in particular to a display support arm. Background Technology
[0002] A monitor support arm is a device specifically designed to support and position a monitor. It typically consists of multiple joints, rods, gas springs, or electric motors, allowing users to flexibly adjust the position and angle of the monitor. Modern monitors are usually designed to be adjustable, including tilting, rotating, lifting, and panning, allowing users to adjust the screen angle and height according to their needs. However, in certain environments, monitors may become unstable or loose due to external factors, such as in factory workshops or next to machines, where continuous vibration may gradually cause the monitor to loosen.
[0003] Existing monitors use built-in damping systems and friction locking mechanisms to allow users to easily adjust the height and angle of the monitor manually. However, these methods can become ineffective or fail due to long-term use, vibration, or environmental factors, making these monitors inconvenient to use in certain environments. Therefore, we propose a monitor support arm to solve this problem. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a display support arm.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A monitor support arm includes a base with a rotating hole at the top. A rotating platform is rotatably mounted on the bottom inner wall of the rotating hole. A stand is fixedly mounted on the top of the rotating platform. A sliding groove is formed at the top of the stand, and a fixed frame is slidably mounted within the sliding groove. An internal groove is formed on one side of the fixed frame, and a rack is fixedly mounted on the inner wall of one side of the internal groove. A square groove is formed on the inner wall of one side of the sliding groove. A common rotating rod is rotatably mounted between the front and rear inner walls of the square groove. A gear and a worm gear are fixedly sleeved on the outer side of the rotating rod, and the gear meshes with the rack. A worm is rotatably mounted on the inner wall of one side of the square groove, and the worm meshes with the worm gear. One end of the worm extends to the outer side of the stand and is fixedly mounted with a knob. A rotating frame is rotatably mounted on the outer side of the fixed frame, and a mounting plate is fixedly connected to one side of the rotating frame.
[0007] Preferably, the outer side of the rotating platform is provided with multiple slots, which are arranged at equal intervals around the circumference. An observation slot is provided on the inner wall of the rotating hole, and the top of the observation slot is open. A transverse slot is provided on one side of the inner wall of the observation slot. An insert plate is horizontally slidably installed in the transverse slot. The insert plate is movably engaged in the corresponding slot. A limiting spring is fixedly connected between one side of the inner wall of the transverse slot and the insert plate.
[0008] Preferably, the top of the transverse groove is provided with a transverse hole, a connecting plate is fixedly installed on the top of the insert plate, a sealing plate is fixedly installed on the top of the connecting plate, and a lever is fixedly installed on one side of the sealing plate.
[0009] Preferably, a rubber ring is fixedly connected to the top of the base, and the rubber ring is slidably and sealingly connected to the top of the rotating platform.
[0010] Preferably, the bottom of the base is provided with multiple arc-shaped grooves, and a counterweight is fixedly installed in the arc-shaped grooves.
[0011] Preferably, the bottom of the base has multiple circular grooves, and shock-absorbing pads are provided in the circular grooves.
[0012] The beneficial effects of this utility model are as follows:
[0013] The worm gear and worm wheel work together to drive the gear to rotate, thereby causing the fixed frame to move vertically. The self-locking performance of the worm gear and worm wheel prevents the fixed frame from loosening due to vibration and avoids the monitor from shaking. The rotating stage is limited by the cooperation of the insert plate and the slot. While adjusting the orientation of the monitor, it ensures that the rotating stage will not swing due to vibration, which is highly reliable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A monitor support arm includes a base 1. A rotating hole is formed at the top of the base 1. A rotating platform 2 is rotatably mounted on the inner wall of the bottom of the rotating hole. A stand 3 is fixedly mounted on the top of the rotating platform 2. A sliding groove is formed at the top of the stand 3. A fixed frame 4 is slidably mounted in the sliding groove. An internal groove is formed on one side of the fixed frame 4. A rack 5 is fixedly mounted on the inner wall of one side of the internal groove. A square groove is formed on the inner wall of one side of the sliding groove. A rotating rod 6 is rotatably mounted between the inner walls of the front and rear sides of the square groove. A gear 8 and a worm gear 7 are fixedly sleeved on the outer side of the rotating rod 6. The gear 8 meshes with the rack 5. A worm 9 is rotatably mounted on the inner wall of one side of the square groove. The worm 9 meshes with the worm gear 7. One end of the worm 9 extends to the outer side of the stand 3 and is fixedly mounted with a knob 10. A rotating frame 11 is rotatably mounted on the outer side of the fixed frame 4. A mounting plate 12 is fixedly connected to one side of the rotating frame 11.
[0023] It should be noted that the rotating frame 11 is equipped with a screw fastening mechanism, meaning that the pitch angle of the rotating frame 11 can only be adjusted by turning the screws to meet the vibration resistance requirements.
[0024] like Figure 2 and Figure 3 As shown, the outer side of the rotating platform 2 is provided with multiple slots 13, which are arranged in a circumferentially at equal intervals. An observation slot 14 is provided on the inner wall of the rotating hole. The top of the observation slot 14 is open. A transverse slot is provided on one side of the inner wall of the observation slot 14. An insert plate 15 is horizontally slidably installed in the transverse slot. The insert plate 15 is movably engaged in the corresponding slot 13. The same limiting spring 16 is fixedly connected between the inner wall of one side of the transverse slot and the insert plate 15.
[0025] A transverse hole is provided at the top of the transverse groove. A connecting plate is fixedly installed on the top of the insert plate 15. A sealing plate 17 is fixedly installed on the top of the connecting plate. A lever plate 18 is fixedly installed on one side of the sealing plate 17. The insert plate 15 is moved to one side by the cooperation of the lever plate 18 and the sealing plate 17.
[0026] like Figure 1 and Figure 1 As shown, a rubber ring 19 is fixedly connected to the top of the base 1. The rubber ring 19 is slidably sealed to the top of the rotating table 2. In industrial production and other environments that are easily contaminated by water vapor, dust or particulate matter, the sealing ring can effectively prevent these substances from entering the rotating hole and causing the rotating table 2 to jam.
[0027] like Figure 5 As shown, the bottom of the base 1 has multiple arc-shaped grooves, and a counterweight 20 is fixedly installed in the arc-shaped grooves. The counterweight ring increases the weight of the entire device, lowers the center of gravity, and prevents the monitor from being knocked over or tilted.
[0028] The bottom of the base 1 has multiple circular grooves, and shock-absorbing pads 21 are installed in the grooves. Factory environments are usually accompanied by the operation of mechanical equipment, which will generate vibrations of varying degrees. The shock-absorbing pads 21 can help absorb these vibrations and prevent them from being transmitted to the display through the device. The work surface is not completely flat, and the shock-absorbing pads 21 can better adapt to these surfaces and keep the support base in a horizontal state.
[0029] The working principle of this utility model is as follows: by rotating the knob 10, the worm gear 9 is driven to rotate. The worm gear 9 drives the gear 8 to rotate through the cooperation of the worm wheel 7 and the rotating rod 6. The gear 8 drives the fixed frame 4 to move vertically through the meshing with the rack 5, thereby adjusting the height of the display body. By pushing the lever to one side, the connecting plate and the insert plate 15 are driven to move to one side, so that the insert plate 15 is disengaged from the slot 13, releasing the limit on the rotating platform 2. The rotating platform 2 is rotated to a suitable angle, and the position of the slot 13 is observed through the observation slot 14, so that the insert plate 15 is re-inserted into the slot 13.
[0030] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described.
