Description

Technical Field

[0001] This utility model relates to the technical field of light sign body support, specifically to a fixing device for street light decorative light signs. Background Technology

[0002] Streetlight decorative signs are an important part of the urban nightscape, fulfilling functional lighting needs while enhancing the quality of the urban landscape through creative design and intelligent technology.

[0003] The fixing brackets of the decorative light sign body of streetlights directly affect the safety and service life of the light sign body. In the existing technology, the decorative light sign body of streetlights mostly adopts clamp type, welding type, etc., to fix the light sign body to the middle or top of the light pole. Because of its simple structure and convenient construction, it is widely used in decoration.

[0004] However, for irregularly shaped landscape light signs or decorative light signs with a large windward area, existing fixing brackets generally only fix the top or middle of the light sign body, lacking a supporting and restraining structure for the bottom of the light sign body. In the event of strong winds or other severe weather, the bottom of the light sign body will be suspended in the air due to the lack of a supporting structure, causing the entire light sign body to sway violently in the wind. This causes the connection between the bracket and the light pole to bear a large force, making it easy for the light sign body to flip over in the wind (leading to loose bolts, bracket deformation, etc.). In severe cases, it may cause the light sign body to fall off, affecting the decorative effect and posing a significant safety hazard. Utility Model Content

[0005] In view of this, the present invention provides a fixing device for decorative street light signs, which can cooperate with the top support frame of the pole and the bottom fixing mechanism to form a double fixing structure, solve the problem of the bottom of the sign body being suspended and swaying, reduce the stress on the connection between the bracket and the pole, avoid bolt loosening, bracket deformation and the sign body falling off, and significantly improve the safety and service life of the sign body in strong wind environments.

[0006] To solve the above-mentioned technical problems, this utility model provides a fixing device for decorative street light signs, including a pole body and a support frame on the pole body. The support frame is used to support the top of the sign body so that the sign body is suspended on the pole body.

[0007] A fixing mechanism is provided at the bottom of the sign body and on the outer wall of the pole body. The fixing mechanism is used to connect the bottom of the sign body to limit the bottom of the sign body from swaying in the wind.

[0008] The fixing mechanism includes a clamp installed on the pole body. A rubber layer is provided between the inner wall of the clamp and the outer wall of the pole body to increase friction and prevent the clamp from sliding vertically down the pole body due to gravity. The rubber layer is sleeved on the outer wall of the pole body and is designed as an open structure (i.e., the two ends of the rubber sleeve are not connected). A mounting plate is provided on the vertical outer wall of the clamp (the mounting plate can be fixedly connected to the vertical outer wall of the clamp).

[0009] An installation block is fixedly connected to the vertical outer wall of the clamp. A snap-fit ​​groove is provided on the upper part of the installation block. The snap-fit ​​groove is set as a blind groove (i.e., it does not completely penetrate the installation block). A snap-fit ​​block is vertically slidably connected in the snap-fit ​​groove. The cross-section of the snap-fit ​​block and the snap-fit ​​groove is set as a convex structure. The snap-fit ​​block is connected to the snap-fit ​​groove by interference fit. The mounting plate is fixedly connected to one vertical surface of the snap-fit ​​block for quick assembly and disassembly of the mounting plate.

[0010] A connecting plate is provided at the bottom of the light sign body. The connecting plate is connected to the bottom of the light sign body through a bearing, so that the light sign body can rotate around the axis of the bearing when strong wind blows, preventing the light sign body from breaking due to strong wind pulling. A fixing rod is provided between the connecting plate and the mounting plate to limit the bottom of the light sign body.

[0011] Nuts are threadedly connected to one end of the fixing rod and to both sides of the connecting plate, and nuts are also threadedly connected to the other end of the fixing rod and to both sides of the mounting plate, in order to improve the speed of disassembly and assembly.

[0012] The support frame includes a mounting component installed on the pole body, with a support rod inserted horizontally along the mounting component, and the sign body is installed on the support rod by a locking pin.

[0013] The mounting component includes a base plate with symmetrically welded wing plates on the upper part. The wing plates are designed in an L-shape, with one side of the wing plate fitting the outer wall of the pole body. The wing plates are used to fix the pole body to support the support rod. A threaded rod is provided on the base plate, and a positioning bolt is connected to the threaded hole through a threaded engagement. The positioning bolt passes through the support rod to fix the support rod to the mounting component.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. Dual limiting structure enhances stability: The top of the sign body is supported by the support frame on the pole body, and the fixed mechanism at the bottom of the sign body restricts swaying. This effectively solves the problem of severe swaying caused by the bottom of the sign body being suspended in the air in the existing technology, reduces the stress on the connection between the bracket and the pole body, avoids loose bolts, bracket deformation and detachment of the sign body, and significantly improves the safety and service life of the sign body in harsh environments such as strong winds.

[0016] 2. Quick assembly and disassembly and convenient maintenance: In the fixing mechanism, the mounting block on the vertical outer wall of the clamp slides with the mounting block through the U-shaped locking groove, which enables quick assembly and disassembly of the mounting plate; the two ends of the fixing rod are connected to the connecting plate and the mounting plate by nuts and threads, which can be assembled and disassembled without tools, greatly improving construction efficiency, and at the same time facilitating the disassembly of parts during transportation and subsequent maintenance and replacement.

[0017] 3. Wind-resistant rotation design enhances environmental adaptability: The connecting plate at the bottom of the light sign body is connected to the light sign body through a bearing, allowing the light sign body to rotate around the bearing axis when strong winds blow, so that the light sign body can adjust its posture with the wind direction and avoid the connection breaking due to strong winds pulling directly; together with the locking pin and conductive slip ring design on the support frame support rod, it ensures that the top of the light sign body rotates synchronously to avoid jamming, taking into account both functionality and wind resistance performance.

[0018] 4. Anti-slip and stable connection structure: The open rubber layer on the inner wall of the clamp increases the friction with the pole body, preventing the clamp from sliding vertically due to gravity or wind, and improving the vertical stability of the fixing mechanism; the open structure of the rubber layer eliminates the need to slip it on from the top of the pole, simplifying the installation process; at the same time, the wing plate of the mounting piece is compatible with the outer wall of the pole, and the support rod is fixed by positioning bolts to prevent the support rod from sliding laterally, enhancing the reliability of the top support.

[0019] 5. Enhanced versatility: The convex cross-section design of the locking block and locking groove effectively resists the risk of detachment caused by lateral wind force; the double nuts on both sides of the fixing rod, in conjunction with the locking washers, improve the vibration resistance of the connection parts and prevent the nuts from loosening during long-term use; the overall modular design makes it suitable for poles and light sign bodies of different specifications. By adjusting parameters such as clamp size and support rod length, it can be widely used for irregularly shaped landscape light sign bodies or decorative light sign bodies with large windward areas, demonstrating strong versatility and market adaptability.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0031] A fixing device for decorative street light signs, such as Figure 1 , 2 As shown: It includes a pole body 101, on which a support frame is provided. The support frame is used to support the top of the light sign body 102, so that the light sign body 102 is suspended on the pole body 101, thereby achieving the purpose of decoration and lighting.

[0032] A fixing mechanism is provided at the bottom of the light sign body 102 and on the outer wall of the pole body 101. The fixing mechanism is used to connect the bottom of the light sign body 102 to limit the bottom of the light sign body 102 from swaying in the wind, and to prevent the light sign body 102 from flipping in the wind, which would cause the bolts to loosen, the bracket to deform, etc., thereby preventing the light sign body 102 from falling off or breaking due to continuous vertical flipping caused by strong wind.

[0033] like Figure 2 , 4 As shown: The fixing mechanism includes a clamp 103 set on the pole body 101. A rubber layer 301 is provided between the inner side wall of the clamp 103 and the outer side wall of the pole body 101 to increase the friction and prevent the clamp 103 from sliding vertically down the pole body 101 due to gravity. A rubber sleeve is fitted on the outer side wall of the pole body 101. In this embodiment, the rubber sleeve is set as a cylindrical structure and is adapted to the pole body 101. The rubber sleeve is set as an open structure (that is, the two ends of the rubber sleeve are not connected), which makes it convenient to install the rubber sleeve without having to put it on from the top of the pole body 101, thus improving the convenience of installation.

[0034] like Figure 2 ,4 As shown: A mounting plate 104 is provided on the vertical outer wall of the clamp 103 (the mounting plate 104 can be fixedly connected to the vertical outer wall of the clamp 103, and can be customized directly during the production of the clamp 103 when purchasing or manufacturing).

[0035] Furthermore, an installation block 201 is fixedly connected to the vertical outer wall of the clamp 103. The upper part of the installation block 201 is provided with a snap-fit ​​groove. The snap-fit ​​groove is set as a blind groove (i.e. it does not completely penetrate the installation block 201). A snap-fit ​​block is vertically slidably connected in the snap-fit ​​groove. The cross-section of the snap-fit ​​block and the snap-fit ​​groove is set as a convex structure, which can prevent the snap-fit ​​block from falling off in the lateral direction (when strong wind blows from the side, it can prevent the snap-fit ​​block from falling out of the snap-fit ​​groove).

[0036] The snap-fit ​​block is connected to the snap-fit ​​groove by interference fit, which allows the snap-fit ​​block to resist upward force and prevent the snap-fit ​​block from coming out of the top of the snap-fit ​​groove, thereby improving the stability of the snap-fit ​​block connection. The mounting plate 104 is fixedly connected to the vertical surface of one side of the snap-fit ​​block and is snapped into the snap-fit ​​groove by the snap-fit ​​block, which is used to quickly install and remove the mounting plate 104. This can improve efficiency during both installation and disassembly, and it is also easy to carry during transportation.

[0037] like Figure 1 , 2 As shown in Figure 3: A connecting plate 105 is provided at the bottom of the light sign body 102 (the connecting plate 105 can be fixedly connected to the bottom end of the light sign body 102). Furthermore, the connecting plate 105 is connected to the bottom end of the light sign body 102 through a bearing, so that the light sign body 102 can rotate around the axis of the bearing when strong wind blows, preventing the light sign body 102 from breaking at the connection point due to strong wind pulling. That is, the light sign body 102 can avoid damage caused by strong wind by rotating, and the aesthetics can be improved by rotating the light sign body 102.

[0038] When using this product, it is important to note that it needs to be installed at the top and bottom of the light sign body 102 using conductive slip rings. The wires should be inserted from the stator end of the slip ring to connect to the power supply, and led out from the rotor end to connect to the internal circuit of the light sign body 102. This is to prevent the wires from breaking due to pulling or tangling during rotation. Alternatively, a universal joint can be used in conjunction with a highly flexible cable.

[0039] like Figure 2 , 3 As shown: A fixing rod 106 is provided between the connecting plate 105 and the mounting plate 104 to limit the bottom end of the light sign body 102. That is, the rigid structure of the fixing rod 106, together with the rigid structure of the clamp 103 and the mounting plate 104, pulls the bottom end of the light sign body 102 to achieve the effect of limiting the bottom end of the light sign body 102.

[0040] Furthermore, one end of the fixing rod 106 and both sides of the connecting plate 105 are connected to nuts 501 by thread engagement. That is, the two nuts 501 are rotated toward both sides of the connecting plate 105 to install the fixing rod 106 on the connecting plate 105, thereby fixing one end of the fixing rod 106. The other end of the fixing rod 106 and both sides of the mounting plate 104 are also connected to nuts 501 by thread engagement. That is, the two nuts 501 are rotated toward both sides of the mounting plate 104 to install the other end of the fixing rod 106 on the mounting plate 104, which is used to improve the disassembly and assembly speed and facilitate storage during transportation.

[0041] Multiple nuts 501 can be fitted with locking washers between the connecting plate 105 and the mounting plate 104 to further improve stability and prevent the nuts 501 from loosening and falling off after long-term use.

[0042] like Figure 1 , 2 As shown in Figure 5: The support frame includes a mounting component installed on the pole body 101. A support rod is inserted horizontally along the mounting component. The light sign body 102 is installed on the support rod by a locking pin. The top of the light sign body 102 can also rotate to prevent the bottom from rotating while the top is fixed and jammed. A conductive slip ring is also required on the locking pin.

[0043] The mounting components include a base plate 402, on which symmetrical wing plates 401 are welded. The wing plates 401 are configured in an L-shape. One side of the wing plate 401 is adapted to the outer wall of the pole body 101, so that the wing plate 401 can be connected to the outer wall of the pole body 101 by bolts or other connectors. The wing plates 401 are used to fix to the pole body 101 to support the support rod. The other side of the two wing plates 401 is used to support and fix the support rod.

[0044] The base plate 402 has a threaded hole, and a positioning bolt is connected to the threaded hole through the threaded engagement. The positioning bolt passes through the support rod and fixes the support rod to the mounting part through the thread engagement, thereby preventing the support rod from sliding laterally on the mounting part and further improving the stability of the support rod when supporting the light sign body 102.

[0045] During installation, the mounting component is fixed to the pole body 101 with bolts, and the support rod is inserted horizontally into the hole opened on the mounting component. Then, the light sign body 102 is installed at both ends of the lower part of the support rod with locking pins.

[0046] After installation, the rubber layer 301 is wrapped around the outer wall of the pole body 101. Simultaneously, the clamp 103 is installed on the rubber layer 301 and locked. After the worker shakes the clamp 103 to ensure a stable connection, the fixing rod 106 is passed sequentially through the mounting plate 104 and the connecting plate 105, and then secured with four nuts 501. Once secured, the installation process is complete. Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
