Description

Technical Field

[0001] This utility model belongs to the field of computer-aided tools, and specifically relates to a multi-screen connection device for computers. Background Technology

[0002] In the current rapid development of the software industry, computer multi-screen connection devices have become an indispensable and important device in software-related scenarios due to their stable support performance and sufficient load-bearing capacity. Their application scenarios are wide and the demand is urgent.

[0003] In software product demonstrations to customers, whether a sales team is introducing the multifunctional modules of office software, the creation process of design software, or demonstrating the exclusive features of customized software to enterprise clients, a large amount of information needs to be presented simultaneously. For example, when demonstrating office software, one screen needs to display the software interface and demonstrate basic functions such as document editing and data statistics; another screen needs to show the software's collaborative application with other office tools; and a third screen needs to present user cases and after-sales service support plans. In this context, a multi-screen display system built with a multi-screen connection device can clearly separate and present information from different dimensions, avoiding the interruption of the presentation rhythm caused by switching windows on a single screen. This allows customers to intuitively understand the software's advantages, helps the sales team efficiently complete product presentations, and increases customer purchase intent.

[0004] At computer software development demonstration conferences, the scenarios and requirements are more complex and diverse. Development teams need to comprehensively showcase their software development results to industry experts, representatives from partner companies, and internal decision-makers. This might involve demonstrating the core functional operation flow of the software on one screen, such as order processing and payment settlement in e-commerce software; displaying the software's backend code architecture, data processing logic, and security protection mechanisms on another screen; and simultaneously presenting the software's performance test reports on other screens, including data on response speed and concurrent processing capabilities, as well as user feedback statistics and future feature iteration plans. Multi-screen connection devices can stably support multiple displays, providing ample space for the simultaneous display of this information. This allows attendees to systematically understand the entire software development process, facilitating technical exchanges, obtaining improvement suggestions, and promoting software optimization and practical application.

[0005] For software developers, multi-screen collaboration is crucial for improving efficiency in daily development work. When writing code, developers often need to open a code editor on one screen to write and modify code in real time; another screen displays software development documentation to review interface definitions, development specifications, and other content; and a third screen runs a test version of the software to view the code's performance and error messages in real time, allowing for timely troubleshooting. Multi-screen connectivity devices can meet developers' needs for multi-screen use, reducing the time wasted by frequent window switching, helping developers focus more on their work, and improving development efficiency and code quality.

[0006] However, existing computer multi-screen connection stands on the market have significant shortcomings in terms of screen arrangement flexibility, making it difficult to adapt to the diverse usage needs of the software industry. These stands are designed with a fixed screen arrangement, supporting only a single, fixed configuration: some stands can only achieve horizontal side-by-side arrangement of two or more screens, suitable only for display or office scenarios with sufficient horizontal width; some stands only support vertical arrangement of two screens, unable to meet the display needs of wide code, long documents, and other content; and a few stands can achieve tilted array arrangement at a specific angle, but this arrangement angle and method are fixed and cannot be adjusted according to actual usage scenarios and needs.

[0007] In practical applications of software, users often need to flexibly change screen layouts due to changes in scenarios or adjustments in requirements. For example, when demonstrating software products to clients in a small conference room, the horizontal width of the space limits the size of the multi-screen setup, which can make the space feel cramped. Switching the screens to a vertical arrangement can effectively save horizontal space, making the presentation environment more comfortable and allowing clients to focus on the content. In large software development demonstration conferences, to ensure that all attendees can clearly see the wide content of the software interface and the complete details of the code architecture diagram, the multi-screen setup needs to be adjusted to a horizontal layout. If the meeting requires the presentation of long document-style test reports or feature iteration plans, the screens need to be switched to a vertical layout to reduce document scrolling and allow attendees to quickly access key information.

[0008] However, the fixed layout design of existing multi-screen connection stands prevents users from freely switching the screen arrangement according to their actual needs. To adapt to different layout requirements, users can only purchase stands with the corresponding layout, which not only significantly increases the equipment procurement and inventory management costs for software companies and software development teams, but also leads to interruptions in software product demonstration processes, reduced efficiency of software development demonstration meetings, and obstacles to developers' daily work due to the time spent on stand replacement. This makes it difficult to meet the core needs of the software industry for flexible information display and high work efficiency. Utility Model Content

[0009] The present invention aims to provide a multi-screen connection device for computers, which is mainly used to solve the technical problem of poor versatility caused by the inability of existing multi-screen connection devices to freely adjust the screen arrangement.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0011] A multi-screen connection device for computers includes a bottom bracket with at least one support column slidably connected to it. A connecting joint is installed at the upper end of the support column, and a crossbar is installed on the connecting joint. The support column and the crossbar can be rotated relative to each other and positioned at a certain relative position through the connecting joint. Mounting components for fixing computer screens are installed at both ends of the crossbar.

[0012] Preferably, the support column includes a first support column and a second support column; the bottom bracket includes a pad, on which a fixing block is fixed, and the fixing block has an inverted T-shaped mounting groove along its length; the bottom of the first support column is configured as a T-shaped slider that matches the mounting groove; the top of the slider extends out of the mounting groove and has a T-shaped vertical sliding groove; the second support column is inserted into the vertical sliding groove and slidably connected to the vertical sliding groove.

[0013] Preferably, the vertical slide groove is provided with a threaded hole, and the second support column is provided with a plurality of through holes that can be coaxially matched with the threaded hole. A screw is threaded into the threaded hole, and one end of the screw is inserted into the through hole to limit the height of the second support column.

[0014] Preferably, the connecting joint includes a fixed plate fixed to the support column, a movable plate provided on the side of the fixed plate away from the support column, and the side of the movable plate away from the fixed plate fixed to the crossbar. The support column, the fixed plate, the movable plate, and the second crossbar are connected by a second screw through and slidably connected in the middle. A clamping block is fixed to the end of the second screw near the movable plate, and a nut is threadedly connected to the end of the second screw near the fixed plate. A second handle for hand rotation is fixed to the end of the nut away from the fixed plate.

[0015] Preferably, the fixed disk has a first toothed groove on the side facing the movable disk, and the movable disk has a second toothed groove on the side facing the fixed disk, and the first toothed groove and the second toothed groove can be interlocked.

[0016] Preferably, the mounting component is a damping ball joint fixed to the end of the crossbar, and the connecting end of the damping ball joint is fixed with a mounting plate for fixing to the back of the computer display screen.

[0017] Preferably, the crossbar has equidistantly arranged mounting holes, and the damping ball joint includes a ball joint support, which is fixed to the crossbar by bolts passing through the mounting holes.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. In this solution, two computer monitors can be connected to one horizontal bar. The number of connected computer monitors can be increased by increasing the number of support columns and horizontal bars. The horizontal bar can rotate on the support columns to adjust the relative position of the two computer monitors. They can be arranged vertically or horizontally. The arrangement of the screens can be adjusted according to the site environment (such as the limitation of horizontal width or vertical height) or the usage requirements (such as the need for the screens to be arranged in a specific horizontal or array manner at the display site).

[0020] 2. By tightening the nut, the clamping block on the second screw can be pressed against the crossbar, which in turn causes the movable disc to press against the fixed disc. After the first tooth groove and the second tooth groove mesh, the relative positions of the fixed disc and the movable disc are locked, thus locking the positions of the two screens.

[0021] 3. The damped ball joint allows the screen to have three degrees of freedom relative to the crossbar, which can be finely adjusted to change the screen's tilt and position according to user needs, making it easier for users to view.

[0022] 4. This device can be designed as a desktop or floor-standing model by adjusting the size of the entire device, making it suitable for use in scenarios such as software development and large-scale product demonstration meetings. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0034] like Figure 1-3 As shown, this computer development multi-screen connection device first includes a bottom support, which serves as the foundation for the entire device, supporting the weight of all subsequent components and the computer display screen 9. This bottom support includes a pad 11 and a fixing block. The pad 11 is made of 8-12mm thick metal sheet or high-strength engineering plastic to ensure sufficient load-bearing strength and stability. The fixing block has a rectangular structure, and its bottom is fixed to the upper surface of the pad 11 by welding or bolting. The length of the fixing block is aligned with the length of the pad 11. An inverted T-shaped mounting groove is formed on the upper surface of the fixing block along its length. The groove opening width is smaller than the bottom width, and the groove depth is 2 / 3 of the fixing block height. Its function is to provide a sliding track for the subsequent installation of the support column and to prevent the support column from detaching from the fixing block during sliding. Protective plates 121 are detachably connected to both ends of the mounting groove, allowing for cleaning of the mounting groove by removing the protective plates 121.

[0035] The support column is used in conjunction with the bottom bracket. The support column can be added according to the on-site usage. Each support column includes a first support column 21 and a second support column 41. The first support column 21 is a rectangular rod structure with a T-shaped slider integrally formed at its bottom. The shape and size of the slider are completely matched with the inverted T-shaped mounting groove on the fixing block. The slider can slide freely along the length of the mounting groove. Through the sliding cooperation between the slider and the mounting groove, the first support column 21 can drive the subsequent connected components to adjust their position in the horizontal direction to adapt to different installation environments and screen spacing requirements. During installation, the protective plates 121 on both sides of the mounting groove are removed, the slider is slid into the mounting groove, and then the protective plates 121 are sealed.

[0036] like Figure 2 As shown, the top of the slider extends a considerable distance beyond the mounting groove. A T-shaped vertical groove 22 is provided on the extended part of the slider. The width of the groove opening is smaller than the width of the groove bottom. The opening of the vertical groove 22 faces the vertical plane, and its function is to provide a vertical sliding channel for the installation of the second support column 41.

[0037] The second support column 41 is also a cuboid rod-shaped structure, slightly longer than the first support column 21. The lower end of the second support column 41 is inserted into the vertical groove 22 extending downwards from the top of the slider of the first support column 21, and the outer wall of the second support column 41 is tightly fitted to the inner wall of the vertical groove 22, allowing the second support column 41 to slide up and down along the length of the vertical groove 22, thereby adjusting the overall height of the support column. The opening of the mounting groove limits the second support column 41, preventing it from coming out. To fix the height of the second support column 41, two threaded holes 23 are provided on the side wall of the vertical groove 22. One threaded hole 23 is specifically located near the groove opening, with its axis perpendicular to the length of the vertical groove 22. The other threaded hole is located below the threaded hole 23. Meanwhile, several through holes 42 are formed along the length of the side wall of the second support column 41. The diameter of these through holes 42 is the same as the diameter of the threaded holes 23, and the distance between two adjacent through holes 42 is 2-3 cm. When the second support column 41 slides to a suitable height, one of the through holes 42 can be coaxially aligned with the threaded hole 23 on the vertical slide groove 22. At this time, a screw 3 is threaded into the threaded hole 23. Its length is greater than the sum of the depth of the threaded hole 23 and the wall thickness of the second support column 41. One end of the screw 3 passes through the threaded hole 23 and then into the corresponding through hole 42. Through the threaded engagement between the screw 3 and the threaded hole 23 and the clamping action of the screw 3 on the second support column 41, the sliding of the second support column 41 in the vertical slide groove 22 is restricted, thereby fixing the overall height of the support column. In order to facilitate the rotation of the screw 3, a first handle is also fixed to the head of the screw 3, which makes it easy for the operator to manually rotate the screw 3.

[0038] At the upper end of the support column, specifically the upper end of the second support column 41, a connecting joint is installed. This connecting joint is used to connect the support column and the crossbar 61, and to realize the relative rotation and positioning between the support column and the crossbar 61. The connecting joint includes a fixed plate, a movable plate 52, a second screw 53, a clamping block 54, a nut 55, and a second handle. The fixed plate has a circular flat plate structure. One side surface of the fixed plate is fixed to the front of the second support column 41 near the upper end by welding or bolting. The side surface of the fixed plate away from the support column has a first toothed groove. The first toothed groove is evenly distributed in a ring on the surface of the fixed plate. The cross-sectional shape of the toothed groove is triangular, and the distance between two adjacent toothed grooves is equal to the width of the toothed groove.

[0039] The movable plate 52 also has a circular flat plate structure. The movable plate 52 is located on the side of the fixed plate away from the support column. On the side surface of the movable plate 52 away from the fixed plate, a crossbar 61 is fixed to the middle of the crossbar 61 by welding or bolt connection. On the side surface of the movable plate 52 facing the fixed plate, a second tooth groove is opened at the position of the first tooth groove on the fixed plate. The cross-sectional shape, tooth height, tooth width and distribution of the second tooth groove are completely consistent with the first tooth groove, so that the first tooth groove and the second tooth groove can be interlocked. When the two are interlocked, the relative rotation between the fixed plate and the movable plate 52 can be restricted, thereby locking the relative position between the crossbar 61 and the support column.

[0040] The second screw 53 is made of high-strength metal and its length is greater than the sum of the thicknesses of the support column, the fixed plate, the movable plate 52 and the crossbar 61. The second screw 53 passes through the support column (specifically the middle part of the second support column 41), the center of the fixed plate, the center of the movable plate 52 and the middle part of the crossbar 61 in sequence. The second screw 53 is slidably connected to the support column, the fixed plate, the movable plate 52 and the crossbar 61. That is, each component has a through hole 42 that matches the diameter of the second screw 53 at the position where the second screw 53 passes through, so that the second screw 53 can slide freely in these through holes 42.

[0041] At one end of the second screw 53 near the movable disc 52, a clamping block 54 is fixed by welding. The clamping block 54 is circular, and its diameter is larger than the diameter of the through hole 42 on the crossbar 61. The function of the clamping block 54 is to clamp the crossbar 61 under the action of the second screw 53, thereby pressing the movable disc 52 onto the fixed disc so that the two cannot rotate relative to each other. A nut 55 is connected to one end of the second screw 53 that extends out of the second support column 41. The outer diameter of the nut 55 is larger than the diameter of the through hole 42 on the support column. A second handle for hand rotation is fixed to the outer circumference of the nut 55 by welding. By rotating the second handle, the nut 55 can be moved along the axis of the second screw 53, thereby moving the second screw 53 and causing the clamping block 54 to clamp or loosen the crossbar 61.

[0042] The crossbar 61 has a rectangular rod-like structure, and its length is determined by the number and size of the computer displays 9 to be connected. The middle part of the crossbar 61 is fixed to the surface of the movable disk 52 in the connecting joint away from the fixed disk. Through the action of the connecting joint, the crossbar 61 can rotate around the axis of the support column, thereby adjusting the relative position of the computer displays 9 connected to both ends of the crossbar 61. On the upper or lower surface of the crossbar 61, there are equidistant mounting holes 62 along the length of the crossbar 61. These mounting holes 62 are circular through holes 42.

[0043] At both ends of the crossbar 61, mounting components for fixing the computer display screen 9 are installed. These mounting components include a damped ball joint 7 and a mounting plate. The structure of the damped ball joint 7 can refer to a conventional damped ball joint 7 structure, including a ball joint support and a connecting end. The direction of ball joint deflection can be selected by adjusting the tightness of the bolts at the bottom of the ball joint support.

[0044] The ball joint support has a cylindrical or square structure, and its bottom has a threaded hole that matches the diameter of the mounting hole 62 on the crossbar 61. A bolt passes through the corresponding mounting hole 62 on the crossbar 61 and is threaded into the threaded hole at the bottom of the ball joint support to fix the ball joint support to the crossbar 61. The user can select different positions of the mounting holes 62 on the crossbar 61 according to the size of the computer display screen 9 to fix the ball joint support and adjust the distance between the two mounting components. At the same time, a slot 63 is provided on the crossbar 61, which allows the user to use a hex wrench to adjust the tightness of the bolt at the bottom of the ball joint support.

[0045] One end of the connecting end of the damping ball joint 7 is fixed to the ball inside the ball joint support, and the other end extends out of the ball joint support. The connecting end can rotate at three angles with the ball inside the ball joint support, namely, flipping up and down, deflecting left and right, and tilting forward and backward. At the same time, the damping ball joint 7 is equipped with a damping structure inside, so that the connecting end has a certain resistance during rotation. When it is rotated to a suitable angle, the connecting end can remain stable in that position and will not rotate on its own.

[0046] A mounting plate is fixed to one end of the damping ball joint 7 that extends out of the ball joint support by welding or threaded connection. The other side of the mounting plate away from the ball joint connection is in contact with the back of the computer display screen 9. Four fixing holes are provided on the mounting plate corresponding to the mounting holes on the back of the computer display screen 9. Screws 3 pass through these fixing holes and are threaded to the mounting holes on the back of the computer display screen 9 to fix the mounting plate to the computer display screen 9, thereby fixing the computer display screen 9 to the crossbar 61.

[0047] In practical use, if two computer monitors 9 need to be connected, one computer monitor 9 can be fixed to each end of a crossbar 61 using mounting components. If the number of computer monitors 9 needs to be increased, multiple support columns can be slidably connected to the fixing block of the bottom bracket. The upper end of each support column is connected to a crossbar 61 via a connecting joint, and the two ends of each crossbar 61 are then fixed to computer monitors 9 using mounting components, thus achieving multi-screen connection. When it is necessary to adjust the arrangement of the computer monitors 9, the nut 55 in the connecting joint can be loosened, causing the clamping block 54 on the second screw 53 to loosen the crossbar 61. At this time, the movable plate 52 separates from the fixed plate, the first tooth groove and the second tooth groove disengage, and the crossbar 61 can rotate around the support column. After adjusting the two computer monitors 9 to a vertical or horizontal arrangement, the nut 55 is tightened again, causing the clamping block 54 to press the crossbar 61 and drive the movable plate 52 to press the fixed plate. The first tooth groove and the second tooth groove engage, locking the relative position of the crossbar 61 and the support column, thus completing the adjustment of the screen arrangement. Meanwhile, the deflection direction of the computer display screen 9 can be finely adjusted by rotating the connecting end of the damping ball joint 7, so that the screen faces an angle that is more conducive to the user's viewing, and the damping structure is used to keep the screen position stable.
