Description

Technical Field

[0001] This utility model relates to the field of screen bracket technology, and in particular to a highly stable connector. Background Technology

[0002] During the installation of displays, advertising screens, and other similar equipment, it is usually necessary to connect the screen mounting bracket to an external fixed structure. Existing connectors are prone to relative rotation under prolonged use or external force, causing the screen angle to shift and affecting the viewing experience. Furthermore, existing connection structures are often inconvenient to assemble and disassemble, lack adjustment flexibility, and fail to meet diverse installation needs.

[0003] Screen stands, such as those used for monitors and televisions, are typically composed of multiple arm segments hinged together by connectors to allow for flexible adjustment of the screen's height, angle, and orientation. The limiting connectors linking the various arm segments are key components enabling multi-degree-of-freedom adjustment.

[0004] Existing limiting connectors typically use screws or bolts to lock the internal clamping structure, fixing the angle between the two connecting parts. However, in practical use, traditional locking structures are prone to slight loosening under the long-term influence of screen weight and vibration, causing relative rotation between the connecting parts and resulting in unexpected screen angle shifts, affecting the viewing experience. Users need to frequently readjust the screen angle, which is very inconvenient. Furthermore, existing connectors are often complex to assemble and repair, and difficult to disassemble.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a highly stable connector to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention discloses a highly stable connector for use in screen brackets, which can effectively prevent unexpected relative rotation between the screen mounting bracket and the external fixing structure or between bracket arm segments.

[0008] This utility model discloses a highly stable connector, including a connecting seat and a guide ring. The connecting seat is connected to an external fixing structure, and the guide ring is connected to a screen mounting bracket.

[0009] The connector includes a clamping assembly, a housing fitted over the clamping assembly, and a circular end cap covering the end of the housing;

[0010] The clamping assembly includes a left clamping block and a right clamping block that can be opened and closed relative to each other. Guide grooves are provided on the opposite side walls of the left clamping block and the guide grooves on both sides together form a guide hole for clamping the guide ring.

[0011] The housing includes a separable left housing and a right housing, which together form a cavity for accommodating the clamping assembly. The side walls of the left housing and the right housing are provided with threaded holes facing each other, and a flathead screw is screwed into the threaded holes. By tightening the screw, the left clamping block and the right clamping block can be driven to close together to clamp the guide ring, thereby fixing the position of the guide ring and realizing the adjustment and locking of the screen angle.

[0012] Both the left and right housings have annular mounting grooves on the outer periphery of the ends with threaded holes, and at least four limiting slots are evenly provided in the circumferential direction of the mounting grooves.

[0013] The circular end cap is provided with an annular flange that fits into the mounting groove. The circular end cap is connected to the outer shell by snapping into the mounting groove through the annular flange. Two buckles are symmetrically arranged on the outer edge of the circular end cap, and the buckles selectively engage with the limiting groove. A slotted boss is provided at the center of the inner end face of the circular end cap. When the circular end cap is installed on the outer shell, the slotted boss is embedded in the slot of the slotted flathead screw head, thereby preventing the screw from rotating.

[0014] The preferred technical solution is that the left clamping block and the right clamping block are connected by a guide pair set along the opening and closing direction to ensure that the two move smoothly during the opening and closing process and do not misalign.

[0015] Preferred technical solution: A limiting pin is provided between the left clamping block and the right clamping block. The limiting pin limits the minimum distance between the left clamping block and the right clamping block to prevent excessive clamping from damaging the guide ring or the clamping block itself.

[0016] Preferred technical solution: The left and right clamping blocks are provided with positioning grooves on their outer sides corresponding to the threaded holes. These positioning grooves are used to accommodate the end of the slotted flathead screw and provide a force application plane.

[0017] Preferred technical solution: A buffer pad is movably connected in the positioning groove to provide buffering between the screw end and the clamping block, reducing direct friction and impact between metals.

[0018] Preferred technical solution: The outer surfaces of the left and right clamping blocks are curved to accommodate installation requirements in different directions.

[0019] Preferred technical solution: The circular end cap has a screw mechanism on the outside, which makes it easy for the user to manually rotate the end cap.

[0020] Preferred technical solution: The cavity enclosed by the left and right shells is a spherical structure.

[0021] Preferred technical solution: The left and right housings are fixedly connected by knurled pins.

[0022] Preferred technical solution: The outer shell is also provided with a pin, one end of which is knurled, and the knurled end of the pin is connected to the left or right shell.

[0023] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0024] This invention fundamentally eliminates the possibility of the screw loosening due to vibration by interlocking the slotted protrusion on the circular end cap with the slotted groove of the locking screw. This ensures a stable and consistent locking force of the clamping assembly on the guide ring, effectively preventing accidental screen angle shifts. The circular end cap uses a snap-fit ​​and limit slot design, allowing for quick assembly and disassembly without tools, greatly facilitating screen bracket installation, initial adjustment, and subsequent maintenance. The clamping assembly and spherical shell function as a universal joint, allowing for adjustments to the screen in multiple directions. Furthermore, all anti-rotation and locking structures are integrated into a compact connector, resulting in a clean appearance that does not affect the overall aesthetics of the screen bracket. The guide pair and limiting pin ensure the stability and precision of the clamping assembly; the buffer pad reduces wear between components; and the arc-shaped contact design ensures more even stress distribution, improving the overall lifespan of the connector.

[0038] Example:

[0039] like Figures 1 to 5 As shown, this utility model discloses a high-stability connector, including a connecting seat 1 and a guide ring 2. The connecting seat 1 is connected to a wall mounting plate or desktop clamp bolt via a pin 114 on its outer shell, and the guide ring 2 is fixedly connected to a support arm or mounting bracket for suspending a screen. The main components of this utility model will be described in detail below:

[0040] The connecting seat 1 has a clamping assembly inside, which consists of a left clamping block 101 and a right clamping block 102. Arc-shaped guide grooves 118 are formed on the opposing surfaces of the left and right clamping blocks 101 and 102. When the left and right clamping blocks 101 and 102 are closed, they form a guide hole for engaging with the outer circumference of the guide ring 2. Precise alignment and smooth opening and closing are achieved between the left and right clamping blocks 101 and 102 through a guide pair 109 consisting of a guide post and a guide hole. A limiting pin 110 spans between the left and right clamping blocks 101 and 102 to ensure a certain gap remains between them in the closed state, maintaining a minimum distance.

[0041] The clamping assembly is enclosed within a housing consisting of a left housing 103 and a right housing 104. The inner cavity of this housing is spherical, fitting the outer spherical surface of the clamping assembly, allowing the clamping assembly to swing within a certain angle. The left housing 103 and the right housing 104 are securely connected together by a knurled pin 113. Threaded holes are symmetrically machined on both side walls of the housing, and two flathead screws 105 are screwed into these holes respectively. When the flathead screws 105 are tightened using tools such as an Allen wrench, the tips of the flathead screws 105 press against the positioning grooves 115 on the outer sides of the left clamping block 101 and the right clamping block 102, pushing them towards the center and ultimately clamping the guide ring 2, achieving locking. A buffer pad 111 is placed inside the positioning groove 115 to prevent direct metal-to-metal contact and distribute pressure. The pin 114 is fixedly connected to the left housing 103 or the right housing 104 by knurling at one end.

[0042] At the end of the outer casing, where the flathead screw 105 is installed, an annular mounting groove 116 is designed, with eight circumferentially distributed limiting slots 117 within the mounting groove 116. A circular end cap 106 is engaged in this mounting groove 116 via its annular flange, allowing the circular end cap 106 to rotate relative to the outer casing. The outer edge of the circular end cap 106 has two symmetrical latches 107. When the circular end cap 106 is rotated to a specific position, the latches 107 engage with the corresponding limiting slots 117, preventing the circular end cap 106 from rotating on its own. At the center of the inner side of the circular end cap 106, a flathead boss 108 is raised. When the end cap is installed in place, this flathead boss 108 precisely inserts into the flathead slot of the corresponding flathead screw 105 head. Thus, once the circular end cap 106 is secured by the latches 107, the flathead screw 105 is completely locked and cannot rotate. The outer side of the circular end cap 106 is also designed with a screw mechanism 112 for easy screwing by the user.

[0043] The working process of this utility model is as follows:

[0044] Insert the guide ring 2 into the guide hole of the clamping assembly, which is not yet locked. At this point, the screen support arm can rotate freely to adjust the screen to the ideal angle.

[0045] After the screen angle is adjusted, use a tool to tighten the two flathead screws 105 to initially clamp the guide ring 2 with the clamping assembly.

[0046] The annular flange of the circular end cap 106 is aligned with the mounting groove 116 of the housing and pushed in. The slotted boss 108 on the inner side of the circular end cap 106 is inserted into the slot of the slotted flathead screw 105. Then the end cap is rotated so that the buckle 107 on it is engaged in a pair of suitable limiting slots 117. During this process, the slotted flathead screw 105 is further tightened to fully lock the guide ring 2.

[0047] When readjustment or disassembly is required, simply rotate the circular end cap 106 in the opposite direction to disengage the buckle 107 from the limiting groove 117, and the circular end cap 106 can be removed. At this time, the flathead screw 105 can be loosened.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
