Description

Technical Field

[0001] This utility model relates to the field of display support technology, and more specifically, to a spring-loaded adjustable bracket. Background Technology

[0002] Currently, TV stands with gas spring adjustable arms shift the center of gravity forward significantly after a TV is mounted, affecting operational stability and testing the strength of the rear structure. Furthermore, the adjustment mechanism is prone to jamming and becomes difficult to adjust. After prolonged use, the wear and tear is severe, resulting in a short overall lifespan and poor performance. Utility Model Content

[0003] The problem solved by this invention is that existing support structures have short lifespans and poor performance.

[0004] To address the aforementioned problems, this utility model provides a spring-loaded adjustable bracket, comprising a base for connecting to a desktop or wall; a mounting bracket for mounting a display screen; a support arm assembly for connecting the base and the mounting bracket; one of the base and the mounting bracket having a rotating seat; one end of the support arm assembly being rotatably connected to the rotating seat, and the other end being rotatably connected to the mounting bracket or the base; the support arm assembly comprising at least one set of first arms, with an elastic element between the first arms; an adjusting assembly comprising an adjusting block and at least one rolling element, one end of the adjusting block being connected to the elastic element, and adjusting the position of the adjusting block to change different tilt angles of the elastic element corresponding to different loads on the first arms; the rotating seat having a receiving cavity for accommodating the adjusting block and the rolling element, and the other end of the adjusting block having a rolling element in contact with the inner wall of the receiving cavity.

[0005] Compared to existing technologies, this technical solution achieves the following advantages: the base is used to install the entire bracket, the adjustment component is used to adjust the extension length of the bracket, and the mounting bracket is used to install the display screen. When the user adjusts the bracket, the adjustment block moves relative to the rotating base. At this time, the rolling element follows the movement direction of the adjustment block and rolls against the cavity wall of the receiving cavity. Compared to the sliding friction generated between the adjustment block and the base in existing technologies, the rolling friction generated by the movement of the rolling element can better protect the adjustment block, making it less prone to wear, and making the user's adjustment less strenuous, thus extending the overall service life of the bracket.

[0006] Furthermore, the adjusting block is provided with a first connecting shaft; the rolling element is engaged with the first connecting shaft.

[0007] Compared with the prior art, the technical effect achieved by this technical solution is that, based on the engagement of the rolling element with the first connecting shaft, the inner wall of the receiving cavity of the rotating seat can just abut against the rolling element, which can limit the displacement of the rolling element along the axial direction of the first connecting shaft and prevent the rolling element from falling out.

[0008] Furthermore, the adjustment assembly also includes an adjustment shaft. The adjustment block has a first mounting position; the adjustment shaft is threaded into the first mounting position.

[0009] Compared with existing technologies, the technical effect achieved by this technical solution is that users can adjust the position of the adjusting block by turning the adjusting shaft.

[0010] Furthermore, the support arm assembly provided by this utility model also includes a second arm and a second connecting shaft. The first arm is disposed close to the adjustment assembly and is movably connected to the adjustment block; one end of the second arm is connected to the first arm via the second connecting shaft, and the other end is connected to the mounting bracket or rotating seat.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are: the first and second arms further extend the support, increasing the support's degree of freedom, making the support adjustment more flexible, and adapting to more usage scenarios.

[0012] Furthermore, the elastic element is a gas spring or spring, with its other end connected to the second connecting shaft.

[0013] Compared to existing technologies, the technical effects achieved by this solution are as follows: The gas spring can effectively adjust the tilt angle of the first arm. Combined with the adjusting block, the tilt angle of the gas spring is changed; the greater the tilt angle, the greater the load-bearing capacity of the first arm. The gas spring is positioned in the first arm, shifting the overall center of gravity of the bracket rearward. Even after the display screen is installed, the overall center of gravity of the bracket will not shift significantly forward, resulting in stronger overall structural stability, further extending the bracket's lifespan, and optimizing the user experience.

[0014] Furthermore, the first arm is a set of parallel linkages. The other end is connected to the second connecting shaft.

[0015] Compared with existing technologies, the technical effect achieved by this technical solution is that the parallel linkage mechanism can strengthen the first arm and protect the gas spring.

[0016] Furthermore, the second arm is provided with a tilt adjustment part at one end near the mounting frame; the mounting frame is provided with a tilt fitting part; the tilt adjustment part is movably connected to the tilt fitting part by adjusting bolts.

[0017] Compared with existing technologies, the technical effect achieved by this technical solution is to further realize the adjustment of the tilt angle of the mounting bracket.

[0018] Furthermore, the inclined fitting part is provided with at least one adjusting hole; the adjusting bolt is movably fitted with the adjusting hole.

[0019] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: after loosening the adjusting bolt, the bolt can be moved within the adjusting hole, and the tilt angle of the mounting bracket will change accordingly. Tightening the adjusting bolt will fix the mounting bracket at the required angle.

[0020] Furthermore, the rotating base is equipped with an adjustment opening, which makes it convenient for the user to adjust the adjustment shaft.

[0021] Furthermore, the rotating base is also equipped with an observation window for observing the position of the adjustment block.

[0022] In summary, the spring arm adjustment bracket provided by this utility model reduces frictional wear of the adjustment component through rolling elements, and the first arm, which is located close to the adjustment component and has a gas spring, can stabilize the center of gravity of the bracket and extend its service life.

Detailed Implementation

[0030] The purpose of this utility model is to provide a spring-loaded adjustable bracket to extend the life of the bracket structure and optimize the user experience.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] See Figures 1 to 5 This utility model provides a spring-loaded adjustable bracket. The base is used to connect to a desktop or wall; the mounting bracket 4 is used to install a display screen; the support arm assembly 3 is used to connect the base and the mounting bracket; one of the base 1 and the mounting bracket 4 is provided with a rotating seat 10, one end of the support arm assembly 3 is rotatably connected to the rotating seat 10, and the other end is rotatably connected to the mounting bracket 4 or the base 1; the support arm assembly 3 includes at least one set of first arms 30, and an elastic element 301 is provided between the first arms 30; the rotating seat 10 is provided with an adjusting assembly 3, which includes an adjusting block 20 and at least one rolling element 203. One end of the adjusting block 20 is connected to the elastic element 301. Adjusting the position of the adjusting block 20 changes the tilt angle of the elastic element 301, which corresponds to different loads on the first arms 30; the rotating seat 10 is provided with a receiving cavity for accommodating the adjusting block 20 and the rolling element 203, and the other end of the adjusting block 20 is provided with a rolling element 203 that abuts against the inner wall of the receiving cavity.

[0033] The base 1 is used to install the entire bracket, the adjustment component is used to adjust the extension length of the bracket, and the mounting bracket 4 is used to install the display screen. When the user adjusts the bracket, the adjustment block 20 moves relative to the rotating base 10. At this time, the rolling element 203 follows the movement direction of the adjustment block 20 and rolls against the cavity wall of the receiving cavity. Compared with the sliding friction generated by the movement between the adjustment block 20 and the base 1 in the prior art, the rolling friction generated by the movement of the rolling element 203 can better protect the adjustment block 20, making it less prone to wear. It also transforms sliding friction into rolling friction, making it easier for the user to adjust the bracket and extending the overall service life of the bracket.

[0034] like Figure 5 As shown, the adjusting block 20 is provided with a first connecting shaft 201; the rolling element 203 is engaged with the first connecting shaft 201.

[0035] With the rolling element 203 engaged with the first connecting shaft 201, the inner wall of the receiving cavity of the rotating seat 10 can abut against the rolling element 203, which can limit the displacement of the rolling element 203 along the axial direction of the first connecting shaft 201 and prevent the rolling element 203 from coming off.

[0036] The adjustment assembly also includes an adjustment shaft 204. The adjustment block 20 has a first mounting position 202; the adjustment shaft 204 is threadedly engaged with the first mounting position 202.

[0037] Users can adjust the position of the adjusting block 20 by turning the adjusting shaft 204.

[0038] like Figure 1As shown, the spring-loaded adjustable bracket provided by this utility model also includes a support arm assembly 3. The support arm assembly 3 includes a first arm 30, a second arm 31, and a second connecting shaft 32. The first arm 30 is disposed close to the adjusting assembly and is movably connected to the adjusting block 20; one end of the second arm 31 is rotatably connected to the first arm 30 through the second connecting shaft 32, and the other end is connected to the mounting bracket 4.

[0039] In other embodiments, such as Figure 6 As shown, one end of the second arm 31 in the support arm assembly 3 is rotatably connected to the first arm 30 via the second connecting shaft 32, and the other end is connected to the base 1. The first arm 30 is connected to the mounting bracket 4 via the rotating seat 10. Due to the distance and angle between the first arm 30 and the mounting bracket 4, when a display is mounted on one end of the mounting bracket 4, the torque on the first arm 30 and the second connecting shaft 32 is relatively small. During long-term use, it is less likely that an angle will form at the connection between the first arm 30 and the second arm 31, causing the entire machine to be unable to rotate freely and stop.

[0040] The first arm 30 and the second arm 31 further extend the support, increasing its degree of freedom and making it more flexible to adjust, thus enabling it to adapt to more usage scenarios.

[0041] like Figure 3 As shown, the first support arm 30 is a set of parallel connecting rods 302, which consists of an upper support arm and a lower support arm.

[0042] The elastic element 301 is a gas spring or spring. It effectively adjusts the length of the first support arm 30. Combined with the adjusting block 20, the tilt angle of the elastic element 301 is changed, allowing for a wider range of height adjustment for the entire bracket. The elastic element 301 is located on the first support arm 30, shifting the bracket's center of gravity rearward. Even after installing a display screen, the center of gravity will not shift significantly forward, resulting in stronger overall structural stability, extended bracket lifespan, and optimized user experience.

[0043] The first arm 30 also includes at least one set of parallel links 302. The parallel links 302 can accommodate the elastic element 301; one end of the parallel links 302 is connected to the rotating seat 10, and the other end is connected to the second connecting shaft 32.

[0044] Preferably, a set of parallel connecting rods 302 are provided on the first support arm 30, and the parallel connecting rods 302 are provided with an interlocking structure, so that the movement of the parallel connecting rods 302 is smoother during adjustment, and the support points and structural stability are increased.

[0045] The parallel link 302 can strengthen the first arm 30 and protect the elastic element 301.

[0046] like Figure 2As shown, the second support arm 31 is provided with a tilt adjustment part 311 at one end near the mounting frame 4; the mounting frame 4 is provided with a tilt fitting part 411; the tilt adjustment part 311 is movably connected to the tilt fitting part 411 by adjusting bolts.

[0047] The tilt adjustment part 311 and the tilt mating part 411 can further adjust the tilt angle of the mounting bracket 4.

[0048] Continue to refer to Figure 2 The inclined fitting part 411 is provided with at least one adjusting waist hole 412; the adjusting bolt is movably fitted with the adjusting waist hole 412.

[0049] A rotating shaft is also provided between the tilt angle fitting part 411 and the tilt angle adjustment part 311, and the tilt angle fitting part 411 can rotate relative to the tilt angle adjustment part 311 with the rotating shaft as a fixed point.

[0050] After the user loosens the adjusting bolt, the bolt can move relative to the adjusting hole 412, and the tilt angle of the mounting bracket 4 will change accordingly. Tightening the adjusting bolt will fix the mounting bracket 4 at the required angle, thereby realizing the adjustment of the mounting bracket angle.

[0051] Refer again Figure 4 The rotating base 10 is provided with an adjustment opening 102, which makes it convenient for the user to adjust the adjustment shaft 204.

[0052] Preferably, the adjustment opening 102 is provided with an adjustment mark on its periphery, which indicates the trend of change in the length or angle of the entire bracket when the adjustment shaft 204 is adjusted in a certain direction.

[0053] The rotating base 10 is also provided with an observation window 103 for observing the position of the adjusting block 20.

[0054] Overall, by turning the adjusting shaft 204, the user adjusts the position of the adjusting block 20. When the adjusting block 20 moves upward, the overall length of the elastic element 301 shortens, and the tilt angle of the elastic element 301 decreases; when the adjusting block 20 moves downward, the overall length of the elastic element 301 lengthens, and the tilt angle of the elastic element 301 increases. The larger the tilt angle of the elastic element 301, the greater the load-bearing force on the first support arm 30. The user, in conjunction with the rotating base 10 and the second support arm 31, can adjust the horizontal orientation of the bracket and its extension length from the desktop or wall. At the same time, the rearward positioning of the first support arm 30 can effectively stabilize the overall center of gravity of the bracket. When adjusting the tilt angle of the mounting bracket 4, the tilt angle adjusting part 311 remains stationary. The user rotates the mounting bracket 4, causing the tilt angle mating part 411 to rotate. After reaching the desired angle, tightening the adjusting bolt clamps the adjusting mating part 411, thus limiting the mounting bracket 4 to the desired angle.

[0055] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
