Description

Technical Field

[0001] This utility model relates to the technical field of monitor brackets, and more particularly to a support rotation structure with multiple adjustable angle ranges. Background Technology

[0002] Monitor stand technology has continuously evolved with the increasing demands for office automation and ergonomics. Early monitors typically used fixed bases, offering only limited tilt adjustment, which could not meet users' diverse needs for viewing angles and space utilization. With the popularization of flat panel displays, universal stands have gradually become mainstream, achieving multi-degree-of-freedom adjustment of the monitor's height, rotation, and tilt through robotic arm structures and multi-joint designs.

[0003] Currently, there are three existing technologies for adjusting the angle of a display: 1) Fixed physical stops: These use non-adjustable bosses or limiting screws inside the rotating joint to physically limit the rotation angle. 2) Friction damping hinges: These use adjusting screws to tighten friction plates, generating damping force to allow for suspension at any angle. 3) Spring-loaded limiting mechanisms: These use spring-loaded pins that engage with slots to achieve segmented limiting.

[0004] The existing technology has the following technical problems:

[0005] 1. Insufficient adaptability to multiple scenarios: Traditional fixed limit solutions cannot simultaneously meet the differentiated rotation angle requirements of different scenarios such as office, design, and presentation.

[0006] 2. Unfriendly human-computer interaction: Most limit adjustments require tools or complex operations, which does not meet the pursuit of a simple operating experience in modern products.

[0007] 3. Space layout limitations: Complex limiting mechanisms often occupy too much space, affecting the overall aesthetics and flexibility of the bracket. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a support rotation structure with multiple adjustable angle ranges.

[0009] The objective of this utility model is achieved through the following technical solution: A support rotation structure with multiple adjustable angle ranges includes an angle adjustment shell, an angle adjustment base, a metal spring, a sliding rod, a push button, an adjustment base limiting ring, a rotation angle guide groove, a groove support shaft, and a bushing. The angle adjustment base is installed on the angle adjustment shell through the adjustment base limiting ring. The angle adjustment base and the angle adjustment shell form a guide groove. The push button is slidably connected to the guide groove. One end of the push button passes through the angle adjustment shell and protrudes outward. The metal spring is installed on the angle adjustment base and resets the sliding rod. The other end of the push button can press one end of the sliding rod, which passes through the angle adjustment base. Under the action of the push button, the other end of the sliding rod is embedded in the rotation angle guide groove. The rotation angle guide groove is rotatably connected to the groove support shaft through the rotation shaft. The groove support shaft is slidably connected to the angle adjustment shell through the bushing.

[0010] Preferably, it also includes an angle adjustment component, which is fixedly connected to the angle adjustment housing via a fixed shaft and screws.

[0011] Preferably, the rotation angle guide groove is provided with a wide angle adjustment groove and a narrow angle adjustment groove, and the sliding rod can be embedded in the wide angle adjustment groove or the narrow angle adjustment groove.

[0012] Preferably, the rotation angle guide groove is further provided with an adjustment shaft hole, through which the rotation shaft passes.

[0013] Preferably, the push button includes a sliding push member, a snap fastener, and a button cap. One end of the sliding push member passes through the angle adjustment housing. The button cap is connected to one end of the sliding push member through the snap fastener. The other end of the sliding push member pushes the sliding rod.

[0014] Preferably, the sliding pusher includes a push rod portion, a guide portion, and an arc-shaped pusher portion. The two ends of the guide portion are fixedly connected to the push rod portion and the arc-shaped pusher portion, respectively. The push rod portion is connected to the button cap through the buckle. The arc-shaped pusher portion is used to push the sliding insert.

[0015] Preferably, the angle adjustment housing is provided with an adjustment cylinder groove, the adjustment cylinder groove is provided with a rotation limiting part and a pusher guide groove, the top of the angle adjustment base is limitedly connected to the rotation limiting part, and the pusher guide groove and the angle adjustment base form a guide groove.

[0016] Preferably, the top of the angle adjustment base is provided with a rotation limiting ring, which is embedded in the angle adjustment housing. The side wall of the angle adjustment base is provided with a push guide, which forms a guide groove with the angle adjustment housing. The push guide is provided with a column hole, and the sliding rod is slidably connected to the column hole. One side of the push guide is provided with a spring limiting groove, and the metal spring is installed in the spring limiting groove.

[0017] This utility model has the following advantages and beneficial effects compared to the prior art:

[0018] This invention simplifies the structure of a support rotation structure with multiple adjustable angle ranges by using an angle adjustment shell, an angle adjustment base, a metal spring, a sliding rod, a push button, an adjustment base limiting ring, a rotation angle guide groove, a groove support shaft, and a bushing. Adjusting the monitor angle requires no additional tools, is simple to operate, and is compact. Furthermore, it enables three different angle ranges of monitor rotation. When the sliding rod is completely disengaged from the adjustment groove, the monitor can rotate freely 360°, meeting the needs of multi-user sharing or large-range adjustments. When the sliding rod is embedded in the narrow angle adjustment groove, the rotation angle is limited to approximately 80°, suitable for fine angle adjustments in personal office work. When the sliding rod is embedded in the wide angle adjustment groove, it provides a large range of rotation of nearly 350°, suitable for scenarios requiring large-angle rotation, such as presentations and demonstrations.

Detailed Implementation

[0031] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0032] like Figures 1-5As shown, the support rotation structure with multiple adjustable angle ranges includes an angle adjusting component 1, an angle adjusting housing 3, an angle adjusting base 4, a metal spring 5, two sliding rods 6, a push button, an adjusting base limiting ring 10, a rotation angle guide groove component 11, a groove support shaft 13, and a bushing 14; the push button includes a sliding push component 7, a snap-fit ​​component 8, and a button cap 9. The upper end of the angle adjusting base 4 is embedded in the bottom of the angle adjusting housing 3, and the angle adjusting housing 3 limits the rotation of the angle adjusting base 4. The lower end of the angle adjusting base 4 is limited by the adjusting base limiting ring 10, which is installed at the bottom of the angle adjusting housing 3. The middle part of the angle adjusting component 1 is rotatably connected to the top of the angle adjusting housing 3 via a fixed shaft 2, and the bottom of the angle adjusting component 1 is fixedly connected to the second fixing screw hole 304 on the top of the angle adjusting housing 3 via screws. The angle adjusting base 4 and the angle adjusting housing 3 form a guide groove, and the sliding push component 7 is slidably connected to the guide groove. The outer end of the sliding pusher 7 passes through the rod adjustment hole 306 of the angle adjustment housing 3 and protrudes outward. A snap fastener 8 is fixed to the bottom of the button cap 9, and the snap fastener 8 is snapped into the outer end of the sliding pusher 7. One end of the metal spring 5 is fixedly installed on the outer wall of the angle adjustment base 4. The outer ends of the two sliding rods 6 are snapped into the other end of the metal spring 5. The sliding pusher 7 slides up and down in the guide groove and can push the outer end of one of the two sliding rods 6. The two sliding rods 6 can slide inward and outward through the angle adjustment base 4. Under the action of the sliding pusher 7, the inner end of the sliding rod 6 is embedded in the rotation angle guide groove 11. Both ends of the rotating shaft 12 are fixed to the groove support shaft 13. The lower end of the rotation angle guide groove 11 is embedded in the top of the groove support shaft 13 and can be horizontally rotatably connected to the middle of the rotating shaft 12. The rotation angle guide groove 11 is located at the top of the groove support shaft 13. The bushing 14 is sleeved on the outer wall of the groove support shaft 13 and is embedded in the angle adjustment base 4. The groove support shaft 13 can rotate relative to the bushing 14.

[0033] Angle adjustment component 1 is used to connect the monitor's support frame. Fixed shaft 2 enhances the support capacity of angle adjustment component 1. Angle adjustment housing 3 precisely nests the angle adjustment base 4 and prevents it from falling off, ensuring concentricity and guiding the sliding of the push button, limiting the range of motion. Angle adjustment base 4 forms the sliding path of the push button and fixes the metal spring 5, allowing the sliding rod 6 to slide in a specific direction. The metal spring 5, made of stainless steel, automatically disengages the sliding rod 6 from the rotation angle guide groove 11 when not pushed, thus resetting the sliding rod 6. The sliding rod 6, also made of stainless steel, features a symmetrical double-rod design, controlling different ranges to improve reliability. The wear-resistant metal material ensures that the limiting accuracy does not diminish after long-term use. The push button pushes the sliding rod 6 into the rotation angle guide groove 11. Adjustment base limiting ring 10 fixes the angle adjustment base 4 from the bottom, preventing axial movement. The rotation angle guide groove 11 defines the rotation limit range of the monitor through the wide angle adjustment groove 1101 and the narrow angle adjustment groove 1102. The groove support shaft 13 supports the rotation angle guide groove 11. The bushing 14 reduces friction between the groove support shaft 13 and the angle adjustment base 4, making rotation smoother. The sliding pusher 7, including the arc-shaped pusher part 703, precisely pushes the sliding rod 6, and the guide part 702 ensures that the sliding is not stuck. The snap fastener 8 is used to quickly connect the button cap 9 to the sliding pusher 7, facilitating disassembly and maintenance. The button cap 9 improves the operator's comfort.

[0034] like Figure 6 As shown, the bottom of the angle adjustment housing 3 is provided with an adjustment cylinder groove 301. The angle adjustment base 4 is embedded in the adjustment cylinder groove 301. The inner top wall of the adjustment cylinder groove 301 is provided with a rotation limiting part 302. The rotation limiting part 302 is provided with two first fixing screw holes 303 and one second fixing screw hole 304. The rotation limiting ring 401 of the angle adjustment base 4 is embedded in the rotation limiting part 302 and connected to the two first fixing screw holes 303 by two screws. The bottom of the angle adjustment component 1 is fixedly connected to the second fixing screw hole 304 by screws. The inner side wall of the adjustment cylinder groove 301 is provided with a pusher guide groove 305. The pusher guide groove 305 and the pusher guide platform 403 of the angle adjustment base 4 form a guide groove. The sliding pusher 7 is slidably connected to the guide groove.

[0035] like Figure 7As shown, the top of the angle adjustment base 4 is provided with a rotation limit ring 401, which is embedded in the rotation limit part 302 of the angle adjustment housing 3. The outer wall of the angle adjustment base 4 is provided with a push guide 403, which, together with the push guide groove 305 of the angle adjustment housing 3, forms a guide groove. The sliding push member 7 of the push button slides in the guide groove. The side wall of the push guide 403 is provided with two through-holes 404, and two sliding rods 6 slide in and out of the two through-holes 404. One side of the push guide 403 is provided with a spring plate limiting groove 402, and one end of the metal spring plate 5 is installed in the spring plate limiting groove 402 by screws.

[0036] like Figure 8 and 9 As shown, the sliding pusher 7 includes a push rod portion 701, a guide portion 702, and an arc-shaped pusher portion 703. The inner surface of the guide portion 702 is fixedly connected to the arc-shaped pusher portion 703, and the outer surface of the guide portion 702 is fixedly connected to the push rod portion 701. The push rod portion 701, the arc-shaped pusher portion 703, and the guide portion 702 are integrally formed. The guide portion 702 slides relative to the guide groove. The arc-shaped pusher portion 703 can push one of the sliding insert rods 6. The push rod portion 701 passes through the rod adjustment hole 306 on the side wall of the angle adjustment housing 3 and engages with the buckle 8.

[0037] like Figure 10 and 11 As shown, the rotation angle guide groove 11 is provided with a wide angle adjustment groove 1101, a narrow angle adjustment groove 1102, and an adjustment shaft hole 1103 from top to bottom. The adjustment shaft hole 1103, the wide angle adjustment groove 1101, and the narrow angle adjustment groove 1102 are parallel to each other and perpendicular to the axial direction of the rotation angle guide groove 11. When the sliding rod 6 is pushed, the sliding rod 6 can be inserted into the wide angle adjustment groove 1101 or the narrow angle adjustment groove 1102 for limitation. The sliding rod 6 can slide along the wide angle adjustment groove 1101 or the narrow angle adjustment groove 1102. The rotation shaft 12 passes through the adjustment shaft hole 1103 and can slide along the adjustment shaft hole 1103.

[0038] Instructions for using the multi-adjustable-angle-range support rotation structure: The push-button guide groove 305 of the angle adjustment housing 3 has three positions, from bottom to top: neutral, first position, and second position. When the push button is in neutral, it is located at the lower end of the push-button guide groove 305, and the push button does not push the two sliding rods 6. Manually rotating the monitor sequentially rotates the angle adjustment component 1 and the angle adjustment housing 3. The angle adjustment housing 3 then rotates the angle adjustment base 4 via the push button, and the angle adjustment base 4 rotates relative to the rotation angle guide groove 11. When the push button is in first position, it is located in the middle of the push-button guide groove 305, i.e., the inner end of the sliding rod 6 is embedded in the narrow angle adjustment groove 1102 of the rotation angle guide groove 11. Manually rotating the monitor sequentially rotates the angle adjustment component 1 and the angle adjustment housing 3. The sliding rod 6 slides relative to the narrow angle adjustment groove 1102 and is restricted by the narrow angle adjustment groove 1102. The rotation angle of the monitor is approximately 80°. When the push button is in the second position, the push button is located at the upper end of the push part guide groove 305, that is, the inner end of the sliding rod 6 is embedded in the wide angle adjustment groove 1101. Manually rotate the display to drive the sliding rod 6 to slide relative to the wide angle adjustment groove 1101. The rotation angle of the display is about 350°.
