Description

Technical Field

[0001] This invention relates to the field of display screen mounting bracket technology, and in particular to a wind resistance bracket. Background Technology

[0002] Currently, most outdoor multi-screen display wind resistance frames adopt a fixed linear structure. The assembly process requires manual fine-tuning of each display screen in the horizontal direction. When constructing curved or wavy multi-screen displays, installers must repeatedly disassemble and reposition the screens to match the design curves. This not only prolongs installation time (requiring multiple angle calibrations and interface re-fixing) but also easily leads to loose screen interfaces and increased splicing errors between modules due to frequent operations. Furthermore, multi-layer wind resistance frame assembly relies on layer-by-layer bolt connections and repeated corrections. After each layer is installed, a level must be used to repeatedly adjust verticality and angle, which is inefficient and prone to structural misalignment due to operational errors. Summary of the Invention

[0003] The main objective of this invention is to provide a wind resistance frame that aims to solve at least one of the aforementioned problems.

[0004] To achieve the above objectives, the present invention proposes a wind resistance frame, comprising:

[0005] The frame includes a first frame and a second frame that rotate about a first axis. The first frame and the second frame are used to mount different displays. The first frame and the second frame are connected in the horizontal direction by an arc-shaped adjustment mechanism that extends along a first arc with the center of the first arc located at the first axis. At least one of the first frame and the second frame is movable relative to the arc-shaped adjustment mechanism. The support frame includes a main support rod and at least two secondary support rods. The at least two secondary support rods are respectively connected to two side frames of the first frame and the second frame that are far apart from each other in the horizontal direction. The top end of the main support rod is provided with a first quick-release piece, and the bottom end of the main support rod is provided with a second quick-release piece. The second quick-release piece of the wind resistance frame can be connected to the first quick-release piece of the wind resistance frame on the lower side.

[0006] In one embodiment, one of the first quick-release member and the second quick-release member includes a rotary snap-fit ​​member that can rotate along the axis of the main support rod, and the other includes a snap-fit ​​groove that extends circumferentially along the main support rod. The rotary snap-fit ​​member can be inserted into the snap-fit ​​groove and move within the snap-fit ​​groove.

[0007] In one embodiment, the main support rod further includes an elastic element and an abutment element. One end of the elastic element is connected to the abutment element, and the other end is connected to the rotating snap-fit ​​element. The elastic element has elastic potential energy that causes the rotating snap-fit ​​element to abut against the groove wall of the snap-fit ​​groove.

[0008] In one embodiment, the main support rod has a receiving groove at one end where the rotating snap-fit ​​member is located. The rotating snap-fit ​​member is also movable along the axial direction of the main support rod. The receiving groove includes a first groove segment and a second groove segment. The first groove segment extends along the axial direction of the main support rod and communicates with the snap-fit ​​groove. The second groove segment extends circumferentially along the main support rod and is located at one end of the first groove segment near the middle of the main support rod. A limiting groove is provided at the end of the second groove segment away from the first groove segment. The rotating snap-fit ​​member is movable within the receiving groove.

[0009] In one embodiment, the rotating snap-fit ​​component includes a movable column disposed on the main support rod, a snap-fit ​​protrusion protruding from the periphery of the movable column, and a movable handle. The snap-fit ​​protrusion is disposed near the end face of the main support rod and is movable within the snap-fit ​​groove and the receiving groove. The movable handle is disposed near the middle of the main support rod, and the movable column abuts against the elastic element.

[0010] In one embodiment, the main support rod is provided with an operating slide groove corresponding to the movable handle. The operating slide groove includes a connected snap-fit ​​slide groove section and a receiving slide groove section. The snap-fit ​​slide groove section includes all the structures of the snap-fit ​​slide groove, and the receiving slide groove section includes all the structures of the receiving slide groove.

[0011] In one embodiment, the arc-shaped adjustment mechanism includes an adjustment member extending along the first arc, one end of which is fixedly connected to one of the first frame and the second frame, and the other end is slidably connected to the other of the first frame and the second frame.

[0012] In one embodiment, the adjusting member is provided with an elongated hole extending along the first arc. In the first frame and the second frame, one of the frames slidably connected to the adjusting member has a first fastener and a first fixing hole. The first fastener passes through the elongated hole and the first fixing hole to connect the adjusting member.

[0013] In one embodiment, the first frame and the second frame, which are fixedly connected to the adjusting member, have a second fastener and a second fixing hole, the second fastener passing through the elongated hole and the second fixing hole.

[0014] In one embodiment, the adjusting member includes a fixing block disposed at the end of the adjusting member, and the side frame of the one of the first frame and the second frame that is fixedly connected to the adjusting member is connected to the fixing block by bolts.

[0015] In one embodiment, both the first frame and the second frame have a fixing protrusion on the side near the adjusting member, and the first fixing hole and the second fixing hole are provided on the fixing protrusion.

[0016] In the technical solution of this invention, the first and second frames of the frame rotate around a first axis, and the arc-shaped adjustment mechanism extends along a first arc centered on the first axis. At least one frame can move relative to the adjustment mechanism. This means that during installation, there is no need to repeatedly disassemble the screen; the relative angle of the two frames can be precisely adjusted simply by guiding the frames along a preset arc trajectory through the arc-shaped adjustment mechanism. This fundamentally avoids interface loosening and splicing errors caused by manual fine-tuning. The secondary support rod connects the horizontally separated side frames of the two frames, dispersing the stress points of the double-sided support structure and effectively resisting the lateral thrust from outdoor wind resistance, reducing the risk of frame deformation. The first and second quick-release components at both ends of the main support rod enable rapid docking of the upper and lower wind resistance frames, replacing the traditional layer-by-layer bolt connection. This eliminates the need to use a level to correct verticality after each layer is installed, significantly improving the efficiency of multi-layer assembly and avoiding structural displacement caused by operational errors in bolt connections. In summary, the arc-shaped adjustment mechanism solves the problem of repeated disassembly and splicing errors in multi-screen installation on curved surfaces; the double-sided auxiliary support rods enhance the structural wind resistance stability; and the quick-release components enable efficient assembly of multi-layer wind resistance frames.

[0017] It should be noted that the wind resistance frame can be disassembled into modular components, including the frame (including the arc-shaped adjustment mechanism), main support rod, and secondary support rod, using quick-release parts. This minimizes space requirements during transportation and storage and prevents parts from being lost. During on-site deployment, multiple layers can be stacked using quick-release parts, and the screen position can be directly adjusted using the arc-shaped adjustment mechanism. No additional adjustment parts need to be assembled, achieving efficient connection of the entire process from unpacking, stacking, adjustment, to use. Attached Figure Description

[0025] This invention proposes a wind resistance frame.

[0026] Please see Figures 1 to 9 In one embodiment of the present invention, the wind resistance frame includes: The frame 100 includes a first frame 11 and a second frame 12 that rotate about a first axis. The first frame 11 and the second frame 12 are used to mount different displays. The first frame 11 and the second frame 12 are connected in the horizontal direction by an arc-shaped adjustment mechanism 14. The arc-shaped adjustment mechanism 14 extends along a first arc, the center of which is located at the first axis. At least one of the first frame 11 and the second frame 12 is movable relative to the arc-shaped adjustment mechanism 14. The support frame 200 includes a main support rod 21 and at least two secondary support rods 22. The at least two secondary support rods 22 are respectively connected to two side frames of the first frame 11 and the second frame 12 that are far apart from each other in the horizontal direction. The top end of the main support rod 21 is provided with a first quick-release piece 23, and the bottom end of the main support rod 21 is provided with a second quick-release piece 24. The second quick-release piece 24 of the wind resistance frame can be connected to the first quick-release piece 23 of the wind resistance frame below.

[0027] In the technical solution of this invention, the first frame 11 and the second frame 12 of the frame 100 rotate around the first axis, and the arc-shaped adjustment mechanism 14 extends along the first arc centered on the first axis. At least one frame can move relative to the adjustment mechanism. That is, during installation, there is no need to repeatedly disassemble the screen. The relative angle of the two frames can be precisely adjusted by guiding the frame along the preset arc trajectory through the arc-shaped adjustment mechanism 14, thus avoiding the loosening of the interface and splicing errors caused by manual fine-tuning. The secondary support rod 22 connects the side frames of the two frames that are far apart in the horizontal direction. The stress points of the double-sided support structure are more dispersed, which can effectively resist the lateral thrust brought by outdoor wind resistance and reduce the risk of frame deformation. The first quick-release piece 23 and the second quick-release piece 24 at both ends of the main support rod 21 can realize the quick docking of the upper and lower wind resistance frames, replacing the traditional layer-by-layer bolt connection. This eliminates the step of correcting the verticality with a level after each layer is installed, greatly improving the efficiency of multi-layer assembly, and avoiding structural displacement caused by bolt connection errors. In summary, the arc-shaped adjustment mechanism 14 solves the problem of repeated disassembly and splicing errors in multi-screen installation on curved surfaces; the double-sided auxiliary support rods 22 enhance the structural wind resistance stability; and the quick-release components enable efficient assembly of multi-layer wind resistance frames.

[0028] It should be noted that the wind resistance frame can be disassembled into modular components, namely the frame 100 (including the arc-shaped adjustment mechanism 14), the main support rod 21, and the secondary support rod 22, through quick-release parts. This results in a small space occupation during transportation and storage, and the components are not easily lost. During on-site deployment, multiple layers can be stacked through quick-release parts, and the position of the screen can be directly adjusted through the arc-shaped adjustment mechanism 14. No additional adjustment components need to be assembled, achieving efficient connection of the entire process of unpacking, stacking, adjustment, and use.

[0029] Please see Figures 1 to 7 In one embodiment, one of the first quick-release member 23 and the second quick-release member 24 includes a rotatable locking member 241 rotatable along the axis of the main support rod 21, and the other includes a locking groove 231 extending circumferentially along the main support rod 21. The rotatable locking member 241 can be inserted into the locking groove 231 and move within it. Compared to the rigid fixation of bolted connections, the rotatable locking member 241 only needs to be rotated after being inserted into the locking groove 231 to complete the locking, without the need for tools such as wrenches, effectively reducing installation time and solving the problem of low efficiency in multi-layer assembly. Furthermore, the locking groove 231 has a clearance notch 232 communicating with the end face of the main support rod 21 to allow the rotatable locking member 241 to move into the locking groove 231. In other embodiments, the clearance notch 232 may not be provided, and the rotatable locking member 241 may be inserted into the locking groove 231 from the outside of the main support rod 21.

[0030] In one embodiment, the main support rod 21 also includes an elastic element 245 and an abutment. One end of the elastic element 245 is connected to the abutment, and the other end is connected to the rotating snap-fit ​​element 241. The elastic element 245 has elastic potential energy to cause the rotating snap-fit ​​element 241 to abut against the groove wall of the snap-fit ​​groove 231, thereby eliminating snap-fit ​​gaps and maintaining tightness of the connection even after multiple disassemblies or long-term wind vibration. Furthermore, the elastic abutment structure has a buffering effect; when outdoor wind resistance acts on the wind resistance frame, the elastic element 245 can absorb some vibration energy, reducing the transmission of vibration to the screen module and preventing the screen interface from loosening due to vibration, further improving the stability of multi-screen splicing. In other embodiments, the elastic element 245 and the abutment may be omitted. When the rotating snap-fit ​​element 241 moves along the snap-fit ​​groove 231 to the end of the snap-fit ​​groove 231 away from the avoidance notch 232, the rotating snap-fit ​​element 241 is welded to the snap-fit ​​groove 231.

[0031] In one embodiment, the main support rod 21 has a receiving groove 246 at one end where a rotating snap-fit ​​member 241 is provided. The rotating snap-fit ​​member 241 is also movable along the axial direction of the main support rod 21. The receiving groove 246 includes a first groove segment 247 and a second groove segment 248. The first groove segment 247 extends along the axial direction of the main support rod 21 and communicates with the snap-fit ​​groove 231. The second groove segment 248 extends circumferentially along the main support rod 21 and is located at one end of the first groove segment 247 near the middle of the main support rod 21. A limiting groove 249 is provided at the end of the second groove segment 248 away from the first groove segment 247. The rotating snap-fit ​​member 241 can move within the receiving groove 246. The receiving groove 246 allows the rotating snap-fit ​​member 241 to be received within the main support rod 21 during the separate storage and handling of the support frame 200. Furthermore, when installing the wind resistance frame adjacent to the main support rod 21 in the axial direction, the first groove segment 247 extends along the axial direction of the main support rod 21 and communicates with the snap-fit ​​groove 231, providing a precise vertical insertion guide for the rotating snap-fit ​​component 241. During installation, the rotating snap-fit ​​component 241 can simply slide down along the first groove segment 247 to enter the snap-fit ​​groove 231. The setting of the limiting groove 249 provides the final limiting fixation for the rotating snap-fit ​​component 241. After the snap-fit ​​component enters the limiting groove 249, the elastic potential energy of the elastic element 245 presses it tightly into the groove, forming a double lock, avoiding the risk of the snap-fit ​​component falling off due to vibration or external force during the storage and handling of the support frame 200. In other embodiments, the receiving groove 246 may not be provided, that is, during the separate storage and handling of the support frame 200, the rotating snap-fit ​​component 241 and the main support rod 21 are placed separately.

[0032] In one embodiment, the rotating locking member 241 includes a movable post 242 disposed on the main support rod 21, a locking protrusion 243 protruding from the peripheral side of the movable post 242, and a movable handle 244. The locking protrusion 243 is disposed near the end face of the main support rod 21 and can move within the locking groove 231 and the receiving groove 246. The movable handle 244 is disposed near the middle of the main support rod 21. The movable post 242 abuts against the elastic member 245. Specifically, the elastic member 245 is configured as a compression spring so that the locking protrusion 243 tends to move towards the locking groove 231. The locking protrusion 243 is disposed near the end face of the main support rod 21, and the design of the movable post 242 abutting against the elastic member 245 can realize the automatic reset function of the locking state, ensuring the stability and reliability of the connection state. The limited movement trajectory of the snap-fit ​​protrusion 243 within the snap-fit ​​groove 231 and the receiving groove 246 effectively avoids the risk of misalignment and ensures precise and controllable snap-fit ​​and release actions. The rational layout of all components integrated into the main support rod 21 effectively reduces the overall structural volume and improves space utilization while achieving functionality. In other embodiments, the rotating snap-fit ​​component 241 may not have the movable column 242, and the snap-fit ​​protrusion 243 and the movable handle 244 may be configured with the same structure, allowing the snap-fit ​​protrusion 243 to extend into the main support rod 21 through the receiving groove 246 and the snap-fit ​​groove 231.

[0033] In one embodiment, the main support rod 21 is provided with an operating slide groove 250 corresponding to the movable handle 244. The operating slide groove 250 includes a connected engaging slide groove section 251 and a receiving slide groove section 252. The engaging slide groove section 251 includes all the structures of the engaging slide groove 231, and the receiving slide groove section 252 includes all the structures of the receiving slide groove 246. The operating slide groove 250 provides a clear movement trajectory for the movable handle 244 and limits the movement range of the movable handle 244. The segmented design of the operating slide groove 250 corresponds to the engaging slide groove 231 and the receiving slide groove 246. The engaging state can be intuitively judged by the position of the movable handle 244 in the operating slide groove 250. That is, when the movable handle 244 is located in the engaging slide groove section 251, the engaging protrusion 243 engages with the adjacent wind resistance frame; when the movable handle 244 is located in the receiving slide groove section 252, the engaging protrusion 243 does not contact the other main support rod 21. Furthermore, the guiding effect of the operating slide 250 makes the movement of the movable handle 244 smoother, avoiding jamming and further improving installation efficiency. In other embodiments, the operating slide 250 may not be provided, and the main support rod 21 may have a clearance opening corresponding to the movable handle 244. The movable handle 244 moves in the clearance opening to adjust the position of the locking protrusion 243 in the locking slide 231 or the receiving slide 246.

[0034] It should be noted that, in this embodiment, the first quick-release component 23 includes a snap-fit ​​groove 231, and the second quick-release component 24 includes a receiving groove 246, an operating groove 250, and a rotating snap-fit ​​component 241. The upper main support rod 21 is connected to the first quick-release component 23 of the lower main support rod 21 through a rotating connector, wherein the snap-fit ​​groove 231 of the first quick-release component 23 and the receiving groove 246 of the second quick-release component 24 form a mating channel. During operation, first grasp the movable handle 244, lift the movable handle 244 upward from the receiving groove in the receiving slide section 252, and slide it from the second groove section 248 of the receiving slide section 252 to the first groove section 247. At this time, the engaging protrusion 243 is lifted upward from the receiving groove in the receiving slide section 246, and slides from the second groove section 248 of the receiving slide section 246 to the first groove section 247. Subsequently, under the elastic force of the elastic element 245, the movable handle 244 slides from the first groove section 247 of the receiving slide section 252 to the clearance notch 232 of the engaging slide section 251, so as to fall into the engaging slide section 251. At this time, the snap-fit ​​protrusion 243 slides from the first groove segment 247 of the receiving slide 246 to the clearance notch 232 of the snap-fit ​​slide 231, so as to fall into the snap-fit ​​slide 231; finally, the movable handle 244 slides towards the end of the snap-fit ​​slide segment 251 away from the clearance notch 232 and abuts against the end of the snap-fit ​​slide segment 251 away from the clearance notch 232. At this time, the snap-fit ​​protrusion 243 slides towards the end of the snap-fit ​​slide 231 away from the clearance notch 232 and abuts against the end of the snap-fit ​​slide 231 away from the clearance notch 232, so as to complete the quick-release connection of the first quick-release piece 23 and the second quick-release piece 24.

[0035] Please see Figures 8 to 9 In one embodiment, the arc-shaped adjustment mechanism 14 includes an adjustment member 141 extending along a first arc. One end of the adjustment member 141 is fixedly connected to one of the first frame 11 and the second frame 12, and the other end is slidably connected to the other of the first frame 11 and the second frame 12. The center of the first arc is coaxial with a first axis, ensuring that the slidably connected frame always rotates around the first axis when moving. The slidable connection allows the relative angle between the two frames to be infinitely adjustable, adapting to different multi-screen splicing requirements. In other embodiments, the two ends of the adjustment member 141 may be movably connected to the first frame 11 and the second frame 12, respectively.

[0036] In one embodiment, the adjusting member 141 is provided with an elongated hole 142 extending along a first arc. One of the first frame 11 and the second frame 12, slidably connected to the adjusting member 141, has a first fastener 144 and a first fixing hole. The first fastener 144 passes through the elongated hole 142 and the first fixing hole to connect to the adjusting member 141. Both the elongated hole 142 and the adjusting member 141 extend along the first arc, ensuring that the frame always moves along a preset arc during adjustment, avoiding offset of the first frame 11 and the second frame 12 during movement. The connection method of the first fastener 144 is simple and reliable; after adjustment to the target angle, only tightening the first fastener 144 is needed to fix the first frame 11 or the second frame 12 to the adjusting member 141. In other embodiments, the one slidably connected to the adjusting member 141 may have a slider sleeved on the adjusting member 141, with a first connecting member passing through the slider and connecting to the adjusting member 141 to complete the fixation.

[0037] In one embodiment, the first frame 11 and the second frame 12, which is fixedly connected to the adjusting member 141, has a second fastener 145 and a second fixing hole, with the second fastener 145 passing through the elongated hole 142 and the second fixing hole. The cooperation between the first fastener 144 and the second fastener 145 enhances the connection strength between the adjusting member 141 and the first frame 11 and the second frame 12, thereby better resisting the torque caused by outdoor wind resistance and preventing frame deformation. In other embodiments, the second fastener 145 may not be provided.

[0038] In one embodiment, the adjusting member 141 includes a fixing block 143 disposed at the end of the adjusting member 141. The side frame of the first frame 11 and the second frame 12, which is fixedly connected to the adjusting member 141, is connected to the fixing block 143 by bolts. The fixing block 143 can significantly increase the contact area between the adjusting member 141 and the side frame of the frame, distributing the preload force generated by bolt tightening and the lateral force during arc adjustment to the contact surface between the fixing block 143 and the frame, preventing frame deformation or wear of bolt holes. When the first frame 11 or the second frame 12, or the adjusting member 141, is damaged, the damaged component can be disassembled and replaced individually without replacing the entire wind resistance frame, significantly reducing subsequent maintenance costs. In other embodiments, the fixing block 143 can also be welded to the side frame.

[0039] In one embodiment, both the first frame 11 and the second frame 12 have a fixing protrusion 13 on the side near the adjusting member 141, and the first fixing hole and the second fixing hole are located on the fixing protrusion 13. Since the main body thickness of the side frame is limited, the fixing protrusion 13 effectively thickens and strengthens the area around the holes, distributing the bolt tightening force and the lateral force during arc adjustment to the entire three-dimensional structure of the protrusion, thus preventing the frame from cracking or deforming due to stress concentration. In other embodiments, the fixing protrusion 13 may not be provided.
