Technical Field
[0001] This utility model relates to the field of display device installation technology, and specifically to a display screen installation device. Background Technology
[0002] In ship navigation operations, the realization of core functions such as navigation monitoring, cabin entertainment, and command and dispatch relies heavily on the stable installation and flexible adjustment of dedicated display screens. These shipboard displays must adapt to the dynamic environment of ship turbulence and swaying, meet the installation requirements of different cabin spaces, and withstand continuous vibration loads and impacts during navigation. However, existing general-purpose display screen installation equipment has significant drawbacks when applied to shipboard scenarios: First, the support stability and vibration resistance are insufficient. Ordinary equipment is mostly a simple support form with one or two pillars, lacking reinforced design for the dynamic environment of ships. Under the multi-directional dynamic loads generated by the ship's roll, pitch, and heave movements, the display screen is prone to violent shaking, displacement, and even loosening of connecting parts and structural deformation, posing safety hazards and affecting the observation of the displayed image, making it difficult to meet the needs of critical scenarios such as navigation monitoring; Second, the adaptability of height and angle adjustment is poor. Different cabins on the ship have large differences in the requirements for display screen installation parameters, and some scenarios require frequent adjustments. The existing equipment relies on manual knobs or gas springs for adjustment, which is inaccurate, difficult to operate in turbulent environments, and has low safety, making it unable to quickly and accurately meet the needs. Thirdly, the reliability and environmental tolerance of the rotary lock are lacking. Ship command and dispatch require the display screen to be rotated to a specific angle or locked in turbulent conditions, but ordinary turntable bearings are prone to wear and jamming in vibration, salt spray, and humid environments, and the existing locking structure is prone to failure under shaking and impact, which cannot guarantee the accuracy of information display. In addition, most ordinary equipment is an integrated, non-removable structure, which restricts the maintenance and operation of the compartment, and lacks protection against salt spray and humidity, making it prone to component corrosion, short circuits, and shortening its service life.
[0003] The aforementioned deficiencies of existing equipment make it difficult to adapt to the dynamic navigation environment and special usage requirements of ships. It cannot meet the stringent requirements of core scenarios such as ship navigation monitoring, command and dispatch for the stability, adjustment accuracy, locking reliability and environmental tolerance of display screen installation equipment. There is an urgent need for a professionally designed ship display screen installation device to solve the above problems. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a display screen installation device with excellent load-bearing performance, smooth lifting and lowering, smooth rotation and a safety protection mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A display screen installation device is characterized by comprising a support base, an installation platform, a lifting support column assembly, and a display screen rotating connection bracket; the support base is equipped with a drive unit; the lifting support column assembly includes at least four lifting supports, each lifting support column being a cylindrical sliding rod structure, with its lower end connected to the drive unit and its upper end connected to the installation platform via bolts, together forming a rigid support frame; the display screen rotating connection bracket is fixed to the upper surface of the installation platform via bolts, and the display screen is rotatably connected to the rotating connection frame via a hinge structure, the rotating connection mechanism enabling the display screen to complete a 360° circumferential rotation around an axis parallel to the plane of the installation platform; The drive unit provides precise power output for adjusting the length of the lifting column. Specifically, it converts electrical or mechanical energy into a force that drives the lifting adjustment components through a built-in motor, causing the lifting column to extend or retract along the outer cylinder axis, thereby achieving height adjustment of the installation platform and display screen. In addition, the overload protection module integrated in the drive unit can automatically cut off the power output when the equipment load exceeds the rated value, preventing component damage caused by overload from the power source level, and comprehensively ensuring the accuracy of equipment adjustment, the stability of the overall structure, and operational safety.
[0006] Furthermore, the drive unit includes a sheath, a transmission screw, a driven gear, a drive gear, and a motor; the sheath and the bearing base form a closed accommodating cavity, the transmission screw is vertically assembled inside the sheath, the driven gear is fixed to the bottom of the transmission screw in a coaxial rigid connection, the drive gear is correspondingly arranged on one side of the driven gear and meshes with the driven gear, and the output shaft of the motor is coaxially fixedly connected to the drive gear, together forming an integrated drive system of "motor power input - gear meshing transmission - screw motion conversion".
[0007] In this embodiment, the drive unit corresponds one-to-one with each set of lifting columns, and the sheath is sealed to the bearing base to form a closed accommodating cavity. During operation, the motor output torque is transmitted to the driven gear through the drive gear, which drives the transmission screw to rotate. Under the action of threaded engagement, the lifting column only moves axially along the axis, thereby adjusting the height of the installation platform. The four sets of lifting columns move synchronously, and through the multi-support structure symmetrically distributed at the four corners, the load of the installation platform and the display screen is stably transmitted to the bearing base along the column axis, ensuring the stability and adjustment accuracy of the overall structure.
[0008] Furthermore, each of the lifting supports is arranged vertically or nearly vertically in the four corner areas between the installation platform and the bearing base, forming a multi-point support structure symmetrically distributed around the geometric center of the installation platform, thereby achieving an indirect connection between the installation platform and the bearing base through directional force transmission.
[0009] Furthermore, the inner wall of the lifting support is provided with an internal thread structure that is compatible with the external thread of the transmission screw. The lifting support is sleeved on the outside of the transmission screw through this thread structure and forms a precision helical fit. Under the action of axial force, the two can generate relative helical motion, and under the radial constraint of the outer cylindrical structure, the rotational motion is converted into linear displacement along the axial direction, together forming an axial telescopic transmission system limited by the outer cylinder.
[0010] The inherent characteristics of the screw drive determine the adjustment accuracy. The pitch of the transmission screw is a fixed parameter. By controlling the number of rotations and the rotation speed of the screw driven by the drive unit, the moving distance and speed of the lifting column can be accurately calculated and controlled, avoiding any slippage or deviation during the movement of the lifting column. Furthermore, the tight engagement of the screw threads can effectively eliminate transmission gaps, further ensuring the stability and positional accuracy of the vertical linear movement of the lifting column. Ultimately, this achieves precise control of the overall length of the lifting column, meeting the accuracy requirements for adjusting the height of the installation platform and display screen.
[0011] Furthermore, the rotating connection bracket for the display screen includes a rotating shaft and an angle positioning component; the rotating shaft is coaxially mounted in the preset rotation center area of the installation platform, and the angle positioning component mechanically locks the rotating shaft after the display screen rotates to the target angle.
[0012] The rotating shaft is fixed to the preset rotation center area of the mounting platform using a coaxial assembly method. It is used to provide centering support for the display screen to rotate around the vertical axis. The precise fit between the shaft and the bearing ensures that the rotation center remains parallel to the plane of the mounting platform. The angle positioning unit acts as a locking execution unit. After the display screen rotates to the target angle, it applies a constraint to the rotating shaft by pressing it with friction plates, restricting its continued rotation, thereby stably locking the display screen at the preset angle position. Furthermore, the rotating connection bracket of the display screen is provided with several angle adjustment holes on both sides. The angle adjustment holes are evenly distributed along the circumference of the rotating shaft. The display screen is detachably fixed at a preset angle by the fastener cooperating with the angle adjustment holes at the corresponding positions. The frame of the display screen is provided with positioning holes that are adapted to the fastener.
[0013] Furthermore, the installation platform includes a frame-type load-bearing structure. This frame structure is rigidly connected by crossbeams located at the bottom of the installation platform to form a load-bearing framework. The crossbeams are pre-set with connection nodes adapted to the liftable support columns. The top of the liftable support column is fixedly connected to the connection nodes one by one. The two are constructed into an integrated load-bearing system through the coordinated transmission of force. This integrated load-bearing system relies on the load distribution characteristics of the frame structure and the axial load-bearing capacity of the support columns to achieve a static load bearing capacity of not less than 100KG, which can form a stable support for the entire area of the large-size display screen and effectively avoid the risk of local stress concentration.
[0014] Furthermore, the bearing base is a detachable cavity structure. The cavity is formed by the base body and the detachable cover plate through a snap-fit assembly to form a sealed assembly. The cavity is planned with a preset accommodating space for the installation of electrical components, and the inner wall of the accommodating space is reserved with installation reference and fixing holes for component positioning. The top of the bearing base is preset with a through wiring hole along the edge or central area of the cavity, and the inner wall of the wiring hole is provided with a scratch-resistant arc structure.
[0015] The advantages and beneficial effects of this utility model are as follows: 1. High stability and high load-bearing capacity: A high-strength overall load-bearing system is constructed by connecting at least four cylindrical sliding rod supports to the frame-type load-bearing structure of the installation platform. The force transmission path is clear and reasonable, effectively distributing the weight of the display screen to each support, avoiding stress concentration, improving static load bearing capacity, and ensuring absolute stability when supporting large-size display screens. 2. High adjustment precision and flexibility: The lifting support column achieves precise length control through the meshing of the transmission screw and gear. The lifting process is smooth, accurate and low noise, solving the problems of laborious and asynchronous manual adjustment. 3. Smooth Rotation and Reliable Locking: The dedicated display screen rotating connection bracket integrates a large-size turntable bearing, ensuring smooth 360° rotation even under heavy loads. Combined with a mechanical angle positioning and locking assembly, it can be quickly locked at any angle to meet multi-view display needs.
[0016] 4. Easy maintenance: The support base has a detachable cavity structure. The cover can be removed by snap-fit components, which facilitates the inspection and replacement of internal electrical components without disassembling the entire equipment. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0019] A display screen installation device includes a support base, an installation platform, a lifting support column assembly, and a display screen rotating connection bracket. The support base is equipped with a drive unit. The lifting support column assembly includes at least four lifting supports, each of which is a cylindrical sliding rod structure. Its lower end is connected to the drive unit, and its upper end is connected to the installation platform by bolts, together forming a rigid support frame. The display screen rotating connection bracket is fixed to the upper surface of the installation platform by bolts, and the display screen is rotatably connected to the rotating connection frame by a hinge structure.
[0020] In this embodiment, the rotating connection bracket of the display screen enables the display screen to complete a 360° circumferential rotation around an axis parallel to the plane of the mounting platform; Preferably, the drive unit includes a sheath, a transmission screw, a driven gear, a drive gear, and a motor; the sheath and the bearing base form a closed accommodating cavity, the transmission screw is vertically assembled inside the sheath, the driven gear is fixed to the bottom of the transmission screw in a coaxial rigid connection, the drive gear is correspondingly arranged on one side of the driven gear and meshes with the driven gear, and the output shaft of the motor is coaxially fixedly connected to the drive gear, together forming an integrated drive system of "motor power input - gear meshing transmission - screw motion conversion".
[0021] In this embodiment, each lifting support column is vertically arranged in the four corner areas between the installation platform and the bearing base, forming a multi-point support structure symmetrically distributed around the geometric center of the installation platform. The indirect connection between the installation platform and the bearing base is achieved through directional force transmission.
[0022] Preferably, the inner wall of the lifting support is provided with an internal thread structure that is compatible with the external thread of the transmission screw. The lifting support is sleeved on the outside of the transmission screw through the thread structure to form a precise helical fit. Under the action of axial force, the two can generate relative helical motion. Under the radial constraint of the external cylindrical structure, the rotational motion is converted into linear displacement along the axial direction, which together constitutes an axial telescopic transmission system limited by the outer cylinder, so as to achieve precise length control.
[0023] In this embodiment, the rotating connection bracket for the display screen includes a rotating shaft and an angle positioning component; the rotating shaft is coaxially mounted in the preset rotation center area of the installation platform, and the angle positioning unit mechanically locks the rotating shaft after the display screen rotates to the target angle.
[0024] Preferably, the rotating connection bracket of the display screen is provided with a plurality of angle adjustment holes on both sides, and the angle adjustment holes are evenly distributed along the circumference of the rotating shaft. The display screen is detachably fixed at a preset angle by the fastener cooperating with the angle adjustment holes at the corresponding positions. The frame of the display screen is provided with positioning holes that are adapted to the fastener.
[0025] The bezel of the display screen to be installed corresponds to the adjustment holes on both sides of the rotating connecting bracket. Two sets of positioning holes are pre-set to match the fixing components. When it is necessary to fix the angle of the display screen, first loosen the positioning pin of the angle positioning component, push the display screen to drive the rotating connecting bracket and the rotating shaft to rotate synchronously. After rotating to the target angle, pass the two fixing components through the positioning holes on the bezel of the display screen and the corresponding angle adjustment holes on both sides of the bracket, and then tighten the nuts to lock them, so that the display screen can be detachably fixed at the preset angle. If the angle needs to be adjusted, simply loosen the nuts and fixing components and repeat the above operation.
[0026] Preferably, in this embodiment, the installation platform adopts a frame-type load-bearing structure. The main body of the frame is composed of multiple crossbeams connected by a rigid connection. The bottom of the frame has a pre-set connection node adapted to the lifting support. Each connection node is provided with a positioning reference surface and a fixing hole. The parallelism error between the positioning reference surface and the upper surface of the installation platform does not exceed 0.03mm. The hole diameter and hole position distribution of the fixing hole are matched with the connection structure at the top of the lifting support, so as to achieve precise alignment and fixed connection between the lifting support and the installation platform.
[0027] Through the above connection method, the installation platform and the lifting support assembly form an integrated load-bearing system. The force transmission path of this system is clear: the load of the display screen is sequentially transferred through the rotating connecting frame, the installation platform, and the lifting support assembly to the load-bearing base, and finally from the load-bearing base to the equipment's installation foundation. Testing shows that the static load-bearing capacity of this integrated load-bearing system is no less than 100KG. Under rated load, the maximum deformation of the installation platform does not exceed 0.5mm, and the stress distribution is uniform with no localized stress concentration.
[0028] Preferably, in this embodiment, the supporting base is a detachable cavity structure. The cavity is assembled in a sealed manner by a base body and a detachable cover plate through a snap-fit assembly. The connection strength of the snap-fit assembly ensures that the cover plate will not loosen or shift under the overall load of the equipment. The cavity interior is divided into a preset accommodating space for the installation of electrical components. The size and layout design of the accommodating space are compatible with mainstream specifications of drive units, control modules, and auxiliary electrical components on the market. The inner wall of the accommodating space is preset with mounting reference surfaces and fixing holes for component positioning, and the outer surface of the cavity is provided with a matrix of heat dissipation holes.
[0029] The top of the support base has symmetrical through-holes along the central area (edge) of its upper surface. The edges of these holes have scratch-resistant arc-shaped structures. The drive unit is housed within the support base's accommodating space, and its power output is connected to the transmission screw of the lifting column via a transmission mechanism, providing power for adjusting the length of the lifting column. The drive unit can be driven by a motor. In this embodiment, the drive unit integrates an overload protection module. This module monitors the drive unit's operating parameters in real time and compares them with preset rated thresholds. When the equipment load exceeds the rated value, the drive unit's operating parameters exceed the threshold, and the overload protection module immediately triggers a protection action, cutting off the drive unit's power output to prevent damage due to overload. Simultaneously, it avoids structural deformation or failure of the lifting column due to excessive force.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
