Description

Technical Field

[0001] This utility model relates to the field of television bracket technology, and in particular to a television trolley bracket. Background Technology

[0002] In scenarios such as audio-visual equipment, conference presentations, and home entertainment, television sets, as an important device for modern home entertainment, come in various types, specifications, and functions. Television sets support network connectivity, allowing users to install applications, watch online videos, play games, and more. As a core component that enables flexible movement and stable support of television sets, the demand for television set trolley stands continues to grow.

[0003] To ensure the overall structural strength, traditional TV trolley stands generally adopt an H-shaped keel design at the bottom of the stand. The H-shaped keel connects the various support components at the bottom of the stand into one unit, distributing the pressure of the TV's weight on the horizontal frame and support rods, and avoiding problems such as horizontal frame deformation and stand tilting during long-term use.

[0004] However, the application of H-shaped keels has certain shortcomings. First, H-shaped keels require a separately designed molding mold, and the processing also involves multiple steps such as cutting, welding, and surface treatment, which significantly increases the manufacturing cost of the bracket and extends the production cycle. Second, H-shaped keels themselves have a certain volume and weight, which will increase the overall weight of the trolley bracket, not only increasing the difficulty of transportation and assembly, but also increasing the load on the moving wheels, affecting the flexibility of the bracket's movement.

[0005] Therefore, it is necessary to provide a TV trolley bracket to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a TV trolley bracket, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a TV trolley bracket, including: two upright supports and two angle supports, and the two upright supports are respectively fixedly connected to the two angle supports. Two sets of fixed vertical support rods and angle support rods are fixedly connected by a horizontal frame one and a horizontal frame two, which are used to connect the vertical support rods and angle support rods laterally to distribute the load. The front and rear sides of the first horizontal frame are each provided with a flange beam. The flange beam is formed by flanging the front and rear sides of the first horizontal frame and abuts between the two corner supports. The front and rear sides of the second horizontal frame are each provided with a flange beam. The flange beam is formed by flanging the front and rear sides of the second horizontal frame and abuts between the two corner supports. The flange beams are used to increase the moment of inertia of the cross sections of the first and second horizontal frames.

[0008] Preferably, the lower part of the angled support rod and the upright support rod form a triangular support frame to enhance the overall stability of the support.

[0009] Preferably, the bottom of the angled support rod is provided with four movable wheels, which are fixed in pairs to the bottom of the two angled support rods to realize the movement of the support.

[0010] Preferably, the top ends of the two support rods are fixedly connected to a fixing plate for mounting the television.

[0011] Preferably, two sliding rods are slidably connected to the fixing plate, and fixing screws are provided on the sliding rods.

[0012] Preferably, the connection node between the upright support and the angled support adopts a rigid connection structure, which can be welded or bolted.

[0013] Compared with related technologies, the TV trolley bracket provided by this utility model has the following beneficial effects: I. This utility model eliminates the need for dedicated processing of H-shaped keel by using a combination structure of upright support rod, angled support rod, and horizontal frame one and horizontal frame two. Each component can adopt standardized production process, reducing mold development costs and process complexity. This not only reduces the overall manufacturing cost but also greatly simplifies the production process, effectively shortens the production cycle, and better adapts to the needs of large-scale and efficient production.

[0014] II. In this utility model, the first flange beam is formed by folding the front and rear sides of the first horizontal frame, and the second flange beam is formed by folding the front and rear sides of the second horizontal frame. The wing-shaped structure formed by folding is equivalent to adding extra support to the first and second horizontal frames, significantly improving the moment of inertia of the cross sections of the first and second horizontal frames. Even under long-term load, the deformation of the horizontal frame can be avoided, ensuring the integrity of the bracket structure and providing a stable lateral support foundation for the television.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1 to 4 A television trolley bracket includes: a vertical support rod 10, a corner support rod 11, a first horizontal frame 20, a second horizontal frame 21, a fixing plate 30, and casters 40. Two vertical support rods 10 and two corner support rods 11 are respectively provided and fixedly connected. The first horizontal frame 20 and the second horizontal frame 21 are both located between the two sets of fixed vertical support rods 10 and corner support rods 11. The fixing plate 30 is fixedly connected to the top of the two vertical support rods 10. Four casters 40 are provided, fixed in pairs to the bottom of the two corner support rods 11. The vertical support rod 10, the corner support rod 11, the first horizontal frame 20, and the second horizontal frame 21 form a stable bracket. The television is mounted on the fixing plate 30, and the bracket can be moved by the casters 40.

[0019] The upper part of the upright support rod 10 is fixedly connected to the fixed plate 30, the middle part is fixedly connected to the upper part of the angled support rod 11 and the first horizontal frame 20, and the bottom part is fixedly connected to the bottom of the angled support rod 11 and the second horizontal frame 21. The angled support rod 11 and the lower part of the upright support rod 10 can form a triangular support frame to provide stable support, ensure the stability of the support, and avoid structural deformation or collapse due to insufficient load-bearing capacity.

[0020] The angled support rod 11 bears the weight transmitted by the upright support rod 10 (including the total load of components such as the TV and the fixed plate 30), and the weight is evenly distributed to the four moving wheels 40 installed at the bottom, so as to avoid overload of a single wheel. At the same time, through cooperation with the first horizontal frame 20 and the second horizontal frame 21, it ensures that the bracket will not tip over or deform when it is stationary or moving.

[0021] Both the front and rear sides of the first horizontal frame 20 are provided with flanged beams 201, which are formed by flanging the front and rear sides of the first horizontal frame 20. The flanged beams 201 abut between the two corner support rods 11. The second horizontal frame 21 is located below the first horizontal frame 20, and its area is larger than that of the first horizontal frame 20. Both the front and rear sides of the second horizontal frame 21 are provided with flanged beams 211, which are formed by flanging the front and rear sides of the second horizontal frame 21. The flanged beams 211 abut between the two corner support rods 11. Frame 1 20 and Horizontal Frame 2 21 are laterally connected to the upright supports 10 and the corner supports 11 on both sides. The presence of flange beam 1 201 and flange beam 2 211 makes the connection points of horizontal frame 1 20, horizontal frame 2 21 with the upright supports 10 and the corner supports 11 more secure. The flanged part can provide additional support and reduce loosening of the connection points, thereby strengthening the anti-swaying ability of the overall frame of longitudinal upright supports 10, horizontal frame and diagonal corner supports 11. Especially when pushing the support to move, it can prevent the structure on both sides from being misaligned due to lateral force.

[0022] Two sliding rods 31 are slidably connected to the mounting plate 30. The sliding rods 31 are equipped with fixing screws. The two sliding rods 31 can be spaced at different intervals according to the TV model. They can be fixed to the mounting plate with fixing screws. The TV can then be installed on the sliding rods 31.

[0023] The working principle of the TV trolley bracket provided by this utility model is as follows: The bracket has two vertical support rods 10 and two angle support rods 11 as its core load-bearing components. The vertical support rods 10 are set vertically to bear the vertical load, and the angle support rods 11 are fixed to the vertical support rods 10 at an inclined angle, forming two sets of symmetrical "L-shaped" support units. The two sets of units are connected laterally by horizontal frame 1 20 and horizontal frame 2 21 to form a rectangular frame structure, which distributes the weight of the TV to the entire bracket and avoids local stress concentration. The flange beam 201 of the first horizontal frame 20 and the flange beam 211 of the second horizontal frame 21 increase the moment of inertia of the cross section of the horizontal frame through the flange design, thereby improving the lateral bending resistance. The fixed connection nodes of the angle support rod 11 and the vertical support rod 10 adopt rigid connection (such as welding or bolt fastening), which further enhances the overall stability of the frame and prevents the support from deforming when it is under load or moved. The fixing plate 30 at the top of the two support rods 10 provides the main mounting surface for the TV. The sliding hanging rod 31 on the fixing plate 30 can slide laterally along the preset track of the mounting plate. The position can be adjusted according to the mounting hole spacing of different TV sizes to adapt to the fixing needs of various TV models. Then, the sliding hanging rod 31 is fixed to the mounting plate with fixing screws to prevent it from slipping and ensure the stability of the TV after installation. Four movable wheels 40 are symmetrically installed in pairs at the bottom of the two angled support rods 11, forming a rectangular distribution of support points. This ensures that the overall weight of the bracket (including the TV) is evenly distributed to each movable wheel 40, preventing overload damage to a single movable wheel 40. The wheels contact the ground via rolling friction, which significantly reduces movement resistance compared to sliding friction. Operators only need to apply a small pushing force to move the bracket.
