Description

Technical Field

[0001] This utility model relates to the field of television accessories technology, specifically a high-strength television center stand. Background Technology

[0002] With technological advancements, current televisions are generally characterized by their thinness, large screens, and high-definition picture quality, leading to the development of corresponding accessories such as wall mounts and TV stands to support the bottom of the television. Existing TV stands are generally divided into split stands and center-mounted stands; center-mounted stands are singular, directly supporting the center of the television. Traditional center-mounted stands have a relatively simple structure, with the connection between the mounting bracket and the base typically secured only by bolts, lacking effective reinforcement. This design results in lower bracket strength, making it prone to loosening over long-term use and affecting the stability of the television. This is especially true when used with large-screen televisions, where the weight of the television makes this simple fixing method more susceptible to structural deformation and loosening. Furthermore, existing stand structures lack effective cushioning and positioning mechanisms when subjected to external impacts, further reducing the reliability and lifespan of the stand. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a high-strength centrally mounted TV stand, which has the advantages of improving the structural strength of the stand, enhancing installation stability, preventing loosening and deformation after long-term use, and extending service life.

[0004] This application provides a high-strength center-mounted TV stand, the technical solution of which is as follows:

[0005] The base has a mounting seat on top, and a reinforcing component on the mounting seat. The reinforcing component includes a reinforcing plate. The bottom of the reinforcing plate has a slot, and the inner cavity of the slot is in close contact with the reinforcing plate. Both ends of the reinforcing plate are fitted with positioning covers. A pull rod is provided on the outside of the positioning cover. A movable plate is movably fitted on the surface of the pull rod, and the bottom of the movable plate is fixedly connected to the base. A spring is fitted at the connection between the inner side of the movable plate and the positioning cover. A pull plate is provided on the outside of the pull rod. A slider is provided at the bottom of the positioning cover. Both sides of the top of the base have grooves that match the slider.

[0006] Furthermore, this application also proposes that the surface of the pull plate is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0007] Furthermore, this application also proposes that the bottom of the positioning cover and the slider are fixedly connected by welding, and the surface of the slider is in close contact with the groove.

[0008] Furthermore, this application also proposes that the inner side of the pull rod is fixedly connected to the positioning cover by a connecting block, and the pull rod is located at the center of the outer side of the positioning cover.

[0009] Furthermore, this application also proposes that the top of the mounting base has four mounting holes, and the four mounting holes are arranged symmetrically in pairs.

[0010] Furthermore, this application also proposes that fixing bolts are fitted at both ends of the inner cavity of the mounting base, and the bottom of the fixing bolts is threadedly connected to the base.

[0011] Furthermore, this application also proposes that fixing holes are provided at the four corners of the base cavity, and the four fixing holes are of the same size.

[0012] As can be seen from the above, the high-strength TV center base and its reinforcing components provided in this application, through the cooperative structure of reinforcing plate, positioning cover, slider and groove, combined with the buffer positioning mechanism of spring and pull rod, effectively disperse the force and suppress structural deformation, thereby improving the overall strength and impact resistance of the base, and has the advantages of improving structural stability, preventing loosening and deformation and extending service life.

[0019] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0020] Please see Figure 1-4 In existing technologies, as televisions become thinner and larger, the center-mounted base 1, as a supporting structure, needs to withstand greater loads. Traditionally, the center-mounted base 1 only connects the mounting bracket 2 and the base 1 via fixing bolts 6, lacking an effective stress-distribution mechanism. When the television is subjected to external forces, stress concentration easily occurs at the connection between the mounting bracket 2 and the base 1, potentially leading to structural deformation or loosening of the connection after prolonged use.

[0021] To address the aforementioned issues, researchers noted that relying solely on bolt fixation was insufficient to withstand dynamic load impacts. Analysis of the force distribution pattern on base 1 revealed the need for a multi-dimensional stress transmission path between mounting base 2 and base 1. Based on this, an adjustable reinforcing component 7 was proposed to be installed below mounting base 2, constructing a self-adjusting composite support structure through a combination of elastic support and sliding positioning.

[0022] Therefore, this application proposes to provide a mounting base 2 with a reinforcing component 7 on the top of the base 1. The reinforcing component 7 includes a reinforcing plate 701 with a slot 709 at the bottom, and positioning covers 702 with sliders 708 fitted at both ends of the reinforcing plate 701. A pull rod 707 connecting a movable plate 705 is provided on the outside of the positioning cover 702. A spring 704 is provided between the movable plate 705 and the positioning cover 702. A pull plate 706 is provided on the outside of the pull rod 707. A groove 5 that cooperates with the slider 708 is provided on the top of the base 1.

[0023] Among them, the reinforcing plate 701 refers to a plate-shaped component that bears lateral stress, and can be made of stamped metal sheet, with its bottom groove 709 forming an embedded connection with the base 1. The positioning cover 702 refers to a guide device that covers the end of the reinforcing plate 701, and can be made of injection-molded engineering plastic shell, constraining the displacement direction of the reinforcing plate 701 through its internal cavity. The slider 708 and the groove 5 refer to a mating structure that forms a sliding pair, and can be made of aluminum alloy guide rail with a trapezoidal cross section, ensuring that the positioning cover 702 moves along a predetermined trajectory. The spring 704 refers to an energy storage element that provides elastic preload, and can be made of helical compression spring 704, adjusting the support stiffness through preload deformation.

[0024] Specifically, during installation, pulling the pull plate 706 drives the positioning cover 702 to move along the slide groove 5, causing the reinforcing plate 701 to engage with the corresponding position on the base 1. The spring 704 provides elastic support between the movable plate 705 and the positioning cover 702. When the television vibrates, the spring 704 absorbs energy and pushes the positioning cover 702 back to its original position. The slider 708 maintains a linear motion trajectory as it slides within the slide groove 5, preventing the positioning cover 702 from deflecting. The reinforcing plate 701 forms surface contact with the base 1 through the slot 709, distributing the load borne by the mounting base 2 to the entire base 1.

[0025] Compared to existing technologies, traditional solutions rely solely on bolts for rigid connections. This solution adds a dual mechanism of elastic support and sliding positioning to the bolt fixing. In existing technologies, the mounting base 2 and the base 1 form a single point of stress concentration. This solution uses a combination of reinforcing plate 701 and slider 708 to create a distributed load transfer path. Traditional structures cannot adapt to dynamic load changes; this solution utilizes the elastic deformation characteristics of spring 704 to achieve dynamic stiffness adjustment.

[0026] Through the above technical solutions, this application effectively disperses the concentrated stress at the connection between the mounting base 2 and the base 1, reducing the risk of fatigue damage to the bolted connection. The elastic support structure can buffer the vibration energy during television operation, preventing the connection structure from loosening due to long-term vibration. The sliding positioning mechanism ensures that the reinforcing component 7 maintains stable displacement under stress, avoiding structural deformation caused by unexpected displacement. The multi-dimensional load transfer path significantly improves the overall structural rigidity of the base 1, extending the service life of the centrally located base 1.

[0027] This application further proposes that the surface of the pull plate 706 is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0028] Among them, the anti-slip threads refer to the concave and convex textures that are continuously distributed along the circumference of the surface of the pull plate 706. Specifically, they can be achieved by roll forming or cutting processes, and are used to increase the coefficient of friction between the operator's hand and the contact surface of the pull plate 706.

[0029] The requirement that there are no fewer than fifteen anti-slip threads means that the distribution density of the threads must cover the effective operating area of ​​the 706 surface of the pull plate. This can be achieved by equidistant arrangement to ensure that sufficient anti-slip effect can be obtained in any direction of force application.

[0030] Specifically, when the operator holds the pull plate 706 to adjust the displacement of the positioning cover 702, the anti-slip threads create a mechanical engagement effect by increasing the roughness of the contact surface. The number of threads is set to no less than fifteen, so that the thread spacing is compressed to completely cover the palm contact area, avoiding slippage due to areas without threads. The continuous distribution of the threads allows the pull plate 706 to evenly distribute the load among the threaded sections when subjected to axial tensile force, preventing stress concentration and surface wear.

[0031] Compared to existing technologies, the adjustment components of traditional center-mounted base 1 typically employ smooth surfaces or sparse anti-slip textures, which can easily lead to slippage when the palm sweats or the angle of force application shifts. This solution, by increasing the distribution density of the anti-slip threads, ensures that the operator obtains a stable fulcrum for force application under different gripping postures. Especially during the assembly of base 1, when the position of the positioning cover 702 needs to be repeatedly adjusted, it can effectively avoid installation errors caused by hand slippage.

[0032] Through the above technical solution, this application solves the problem of poor installation stability caused by insufficient anti-slip structure of the traditional base 1 adjustment component. By increasing the density of the thread distribution, the reliability of force transmission between the operator and the adjustment component is enhanced, ensuring that the movement of the positioning cover 702 in the slide groove 5 is precise and controllable, thereby improving the assembly accuracy of the overall structure of the base 1.

[0033] This application further proposes that the bottom of the positioning cover 702 and the slider 708 are fixedly connected by welding, and the surface of the slider 708 is in close contact with the groove 5.

[0034] Among them, the fixed connection by welding refers to the permanent connection between the bottom of the positioning cover 702 and the slider 708 by filling the joint with molten metal. Specifically, it can be achieved by arc welding or laser welding, which improves the overall structure by eliminating the connection gap.

[0035] The close contact between the surface of the slider 708 and the groove 5 means that the outer contour of the slider 708 and the inner wall of the groove 5 form an interference fit or clearance fit. This can be achieved by precision machining, which enhances sliding stability by limiting the swaying amplitude of the slider 708 in the groove 5.

[0036] Specifically, during the assembly process of the top slide groove 5 of the base 1 and the slider 708, the welding process makes the positioning cover 702 and the slider 708 form an integral structure that cannot be disassembled, avoiding stress concentration that may occur with bolt connection; after the surface of the slider 708 is polished, it forms a uniform contact surface with the inner wall of the slide groove 5, and maintains the straightness of the sliding trajectory under the action of the spring 704, thereby ensuring the accurate positioning of the reinforcing component 7 on the base 1.

[0037] Compared with the existing technology, the connection between the positioning cover 702 and the slider 708 in the existing base 1 is mostly fastened with bolts or snap-fit, which poses a risk of loosening due to vibration. However, this solution eliminates the connection gap by welding, and with the precise contact between the slider 708 and the slide groove 5, the positioning cover 702 can effectively distribute stress when bearing the load of the TV, and avoid the mounting base 2 from loosening due to local deformation.

[0038] Through the above technical solution, this application achieves a rigid connection between the positioning cover 702 and the slider 708, ensuring the stable sliding trajectory of the reinforcing component 7 on the base 1, while reducing the risk of structural failure of the mounting base 2 due to loosening of the connecting parts, thereby improving the overall load-bearing capacity of the central base 1 of the TV.

[0039] This application further proposes that the inner side of the pull rod 707 is fixedly connected to the positioning cover 702 by a connecting block 703, and the pull rod 707 is located at the center of the outer side of the positioning cover 702.

[0040] The connecting block 703 is a component used to rigidly connect the pull rod 707 and the positioning cover 702. It can be made of metal or high-strength plastic. Its function is to enhance the connection strength between the pull rod 707 and the positioning cover 702 and avoid structural deformation due to uneven force.

[0041] The position of the pull rod 707 at the center of the outer side of the positioning cover 702 means that the axis of the pull rod 707 coincides with the axis of symmetry of the positioning cover 702. This can be achieved by setting symmetrically distributed fixed points on the outer side of the positioning cover 702. Its function is to ensure that the direction of force applied by the pull rod 707 is consistent with the movement trajectory of the positioning cover 702, thereby avoiding jamming caused by offset.

[0042] Specifically, the pull rod 707 is fixedly connected to the positioning cover 702 via the connecting block 703, allowing the pull rod 707 to evenly distribute the load to the positioning cover 702 when subjected to external force. Simultaneously, the central position of the pull rod 707 ensures its balance during horizontal movement, preventing frictional resistance between the positioning cover 702 and the slide groove 5 due to unilateral force application. When the position of the positioning cover 702 needs adjustment, the symmetrical force applied by the pull rod 707 drives the slider 708 to slide smoothly along the slide groove 5, while the rigid connection of the connecting block 703 effectively prevents relative displacement between the pull rod 707 and the positioning cover 702.

[0043] Compared to existing technologies, traditional solutions typically use direct welding or bolts to connect the pull rod 707 and the positioning cover 702, which is prone to fatigue fracture due to long-term stress. Furthermore, the off-center position of the pull rod 707 may cause the positioning cover 702 to tilt during sliding. This solution, through the load-sharing function of the connecting block 703 and the central positioning design, improves connection reliability and optimizes the stability of the motion trajectory.

[0044] Through the above technical solution, this application solves the problem of loosening caused by insufficient strength of the connection structure of the mounting base 2. Through rigid connection and symmetrical force application design, the structural stability of the base 1 when supporting the TV is significantly improved, while reducing the risk of component wear caused by force offset and extending the service life of the base 1.

[0045] This application further proposes that the top of the mounting base 2 has four mounting holes 3, which are arranged symmetrically in pairs.

[0046] Among them, mounting hole 3 refers to a through hole or threaded hole used to fix the television set. Specifically, it can be achieved by drilling or stamping. Its function is to provide a through channel for the bolt to achieve the mechanical connection between the mounting base 2 and the television set.

[0047] The symmetrical arrangement refers to the four mounting holes 3 being distributed in a mirror symmetrical manner along the central axis of the mounting base 2. Specifically, this can be achieved by using two sets of holes with equal spacing and overlapping axes, such as forming a rectangular array on the top of the mounting base 2. Its function is to balance the load distribution through a symmetrical structure.

[0048] Specifically, the four mounting holes 3 on the top of the mounting base 2 are arranged symmetrically in pairs to form a geometrically symmetrical structure. When installing the television, it can be fixed by passing four sets of bolts through these symmetrical holes. Because the support points formed by the symmetrical holes are evenly distributed on the mounting surface, the load is distributed to four contact areas, avoiding deformation of the mounting base 2 caused by concentrated force on one side. For example, the mounting holes 3 can be symmetrically distributed in two sets along the longitudinal centerline of the mounting base 2, and the lateral spacing of each set of holes can be adjusted according to the position of the screw holes on the bottom of the television.

[0049] Compared to existing technologies, traditional mounting bases 2 typically have only two asymmetrically distributed mounting holes 3, causing the force to concentrate on one side when the television is fixed, which can easily lead to local deformation of the mounting base 2. In contrast, this solution uses four symmetrically distributed mounting holes 3 to form a multi-support point structure, which allows the load to be evenly distributed to the entire base 1.

[0050] Through the above technical solution, this application solves the problem of insufficient strength of the mounting base 2 due to uneven force distribution. By using four symmetrically distributed mounting holes 3 to form a stable support structure, the local stress of the mounting base 2 when bearing the television is effectively reduced, thereby improving the connection reliability and preventing loosening.

[0051] This application further proposes that both ends of the inner cavity of the mounting base 2 are fitted with fixing bolts 6, and the bottom of the fixing bolts 6 is threadedly connected to the base 1.

[0052] Among them, the fixing bolt 6 refers to the threaded fastener used to achieve mechanical fastening. Specifically, it can be a hexagonal head bolt or a flange bolt. It passes through both sides of the mounting base 2 and forms a rigid connection with the base 1 through threads. The threaded connection refers to a detachable fastening structure formed by the meshing of internal and external threads. Specifically, it can be achieved by using metric coarse threads or fine threads. The axial preload generated by the thread meshing can suppress the relative displacement between the mounting base 2 and the base 1.

[0053] Specifically, the fixing bolts 6 at both ends of the inner cavity of the mounting base 2 penetrate its sidewalls and are screwed into the pre-set threaded holes of the base 1 through threaded engagement. When the bolt head contacts the outer wall of the mounting base 2, the axial tensile force generated by the bolt shank creates a clamping force between the mounting base 2 and the base 1, thereby eliminating the gap between their contact surfaces. The symmetrically distributed bolts at both ends form a two-point constraint, which can balance the torsional moment of the mounting base 2 under lateral loads and avoid stress concentration caused by single-point fixing.

[0054] Compared to existing technologies, traditional mounting bases 2 use only a single bolt for fixing or an asymmetrical connection method, which is prone to local deformation when bearing the weight of the television. This solution uses a threaded connection structure with symmetrical arrangement at both ends to evenly distribute the load to the base 1, effectively reducing the risk of deformation at the connection points.

[0055] Through the above technical solution, this application solves the problem of loosening caused by insufficient connection strength between the mounting base 2 and the base 1. The rigid constraint formed by the symmetrical fixation of the double bolts significantly improves the structural stability, while the detachable nature of the threaded connection facilitates installation and maintenance.

[0056] This application further proposes that the four corners of the inner cavity of the base 1 are provided with fixing holes 4, and the four fixing holes 4 are of the same size.

[0057] The fixing holes 4 refer to the through holes located at the four corners of the base 1. These holes can be circular or square, and their diameter can be adjusted according to installation requirements, for example, ranging from 5mm to 10mm. This feature creates a uniformly supported structure through a symmetrical layout at the four corners.

[0058] The consistent size refers to the fact that the diameter and depth of the four fixing holes 4 are exactly the same. This can be achieved by using standardized mold processing, such as simultaneously machining the four holes using a CNC machine tool. This feature ensures that the fasteners are subjected to balanced forces during installation.

[0059] Specifically, the fixing holes 4 at the four corners of the base 1 form a symmetrical support system through a standardized hole layout. When the base 1 is fixed to the ground or a bearing surface, the four fixing holes 4 can be simultaneously connected to fasteners to form multi-directional constraints. Since the holes are distributed at the four corners of the base 1 and have the same diameter, the preload generated by the fasteners during installation can be evenly distributed within the plane of the base 1, avoiding local stress concentration caused by hole offset or diameter differences. During installation, bolts or expansion screws of uniform specifications, such as M6 or M8 standard parts, can be used, and a stable support surface can be formed by synchronous tightening at the four corners.

[0060] Compared with existing technologies, traditional bases 1 typically only have a single row of fixing holes 4 on both sides, resulting in a lack of constraint in the central area of ​​the base 1 after installation. This solution uses symmetrically distributed equal-diameter fixing holes 4 at the four corners to expand the contact area between the base 1 and the bearing surface from linear support to area support. When bearing the weight of the television, the load can be evenly transferred to the bearing surface, effectively suppressing deformation or displacement of the base 1 caused by uneven force.

[0061] Through the above technical solution, this application solves the problem of insufficient installation stability of traditional TV stand 1. The symmetrical layout of the four corner fixing holes 4 forms a stable quadrilateral support structure, which can offset the lateral force generated by screen vibration during TV operation and prevent relative sliding between the stand 1 and the bearing surface. At the same time, the standardized hole design eliminates the need to adjust the fastener specifications during installation, reducing assembly complexity and the probability of operational errors.

[0062] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
