[0006] To achieve this purpose, the utility model adopts the following technical scheme:

[0007] In a first aspect, the utility model provides a support unit, which comprises:

[0008] A support rod is fixedly connected with a display device and has opposite first and second ends.

[0009] A first connector is provided on the first end, and the first connector has a clamping piece that can be inserted into the second end of an adjacent support rod.

[0010] A second connector is rotatably connected to the second end and has an insertion state and a locking state. In the insertion state, the clamping piece can be inserted into the second connector. In the locking state, the second connector is clamped and fixed with the clamping piece.

[0011] Optionally, the second end of the support rod has a mounting hole, and the second connector comprises:

[0012] A connecting cylinder is rotatably connected to the mounting hole and partially extends out of the mounting hole, and a side wall of the connecting cylinder is provided with an insertion hole for inserting the clamping piece, and a hole wall of the insertion hole is provided with a sliding channel, and the clamping piece slides into the sliding channel when the connecting cylinder rotates and is clamped and fixed with the connecting cylinder.

[0013] Optionally, the connecting cylinder is provided with a locking hole, and the second connector is provided with a locking portion, and in the plug-in state and the locking state, the locking portion can be plugged into the locking hole.

[0014] Optionally, the locking hole corresponds to the hole wall of the mounting hole, and the locking portion is elastically connected to the hole wall of the mounting hole.

[0015] Optionally, the outer side wall of the connecting cylinder has a limiting groove extending in the circumferential direction and corresponding to the hole wall of the mounting hole, and both ends of the limiting groove are provided with a locking hole.

[0016] Optionally, the clamping piece comprises:

[0017] A clamping block is fixedly connected to the first connector, and the clamping block has a clamping head that can be plugged into the second connector and clamped and fixed with the second connector.

[0018] Optionally, the support unit further comprises:

[0020] Optionally, the support unit further comprises:

[0021] A fixing portion is plugged into the lifting cylinder and at least partially inserted into the first connector to fix the lifting cylinder.

[0022] Optionally, the support unit further comprises:

[0023] A connecting rod has one end connected to the support rod and the other end hinged with a first fixing block fixedly connected to the display device.

[0024] A telescopic rod has one end connected to the support rod and the other end capable of telescoping relative to the support rod and hinged with a second fixing block fixedly connected to the display device.

[0025] In a second aspect, the utility model also provides an anti-wind frame which is used for fixing and installing a display device and comprises:

[0026] A plurality of support units according to any one of the first aspects are in abutment in sequence and are all fixedly connected to the display device.

[0027] The beneficial effects of this utility model are:

[0028] Firstly, when assembling the two support units, simply insert the snap-fit ​​piece on the first connector into the second end of the adjacent support rod and then into the second connector. Rotating the second connector switches it from the plugged-in state to the locked state, securing the snap-fit ​​piece with the second connector. This locks the first connector to the second connector of the adjacent support rod, enabling rapid assembly of the two support units. Similarly, during disassembly, simply rotating the second connector switches it from the locked state to the plugged-in state, releasing the snap-fit ​​piece and facilitating quick disassembly of the two support units. Therefore, when assembling the support unit outdoors, the first and second connectors at both ends of the support rods allow for rapid installation and disassembly between adjacent support rods, eliminating the need to tighten multiple high-strength bolts. This effectively reduces assembly and disassembly difficulty and improves efficiency. Furthermore, the snap-fit ​​piece and second connector can be manufactured along with the support rods, resulting in lower manufacturing costs. Each support rod only requires one snap-fit ​​piece and one second connector, further reducing overall assembly and disassembly costs. Meanwhile, since the snap-fit ​​component is directly inserted into the second end of the support rod and into the second connector, on the one hand, the snap-fit ​​force generated during snap-fit ​​is close to or even coincides with the axis of the support rod. This helps to ensure that the force on the connection point of the two adjacent support rods is uniform after assembly, effectively ensuring that the axes of the two adjacent support rods remain collinear, thereby improving the overall stability and connection strength after assembly. On the other hand, it also allows the snap-fit ​​structure to be fully contained inside the support rod, reducing exposed structures and improving the overall neatness.

[0029] Secondly, by quickly splicing and fixing multiple support units, the overall assembly and fixing of the windproof frame can be completed quickly, which facilitates the rapid installation and disassembly of the display device, thereby effectively reducing the overall assembly and disassembly difficulty and improving the assembly and disassembly efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This utility model discloses a support unit and a wind-resistant frame.

[0047] Reference Figures 1 to 6 The support unit includes a support rod 1, a first connector 2, and a second connector 3. The support rod 1 is fixedly connected to the display device and has a first end and a second end opposite to each other; the first connector 2 is disposed at the first end and has a snap-fit ​​member 21, which can be inserted into the second end of the adjacent support rod 1; the second connector 3 is rotatably connected to the second end and has an insertion state and a locking state. In the insertion state, the snap-fit ​​member 21 can be inserted into the second connector 3, and in the locking state, the second connector 3 is snapped and fixed with the snap-fit ​​member 21.

[0048] Specifically, the support rod 1 extends vertically, with its upper end serving as the first end and its lower end as the second end. The first connector 2 is cylindrical, and its axis coincides with the axis of the support rod 1. The lower end of the first connector 2 is inserted into the first end, and the two can be fixedly connected by means of bonding, welding, snap-fitting, or bolting. A snap-fitting element 21 is provided at the end of the first connector 2 away from the support rod 1. A slot or other structure is formed on the side wall of the second end of the support rod 1. The second connector 3 is rotatably connected in the slot, so that the second connector 3 can switch between the inserted state and the locked state. A hole for inserting the snap-fitting element 21 is formed on the end face of the second end, and this hole communicates with the second connector 3. The second connector 3 has a snap-fitting structure such as a slot or a hook. In the inserted state of the second connector 3, the snap-fitting element 21 and the snap-fitting structure are inserted and engaged with each other. In the locked state, the snap-fitting element 21 and the snap-fitting structure are snapped and fixed.

[0049] When assembling the two support units, simply insert the snap-fit ​​piece 21 on the first connector 2 into the second end of the adjacent support rod 1 and into the second connector 3, then rotate the second connector 3 to switch it from the plugged-in state to the locked state, so that the snap-fit ​​piece 21 and the second connector 3 form a snap-fit ​​fixation, which can lock the first connector 2 and the second connector 3 of the adjacent support rod 1, thus completing the quick assembly between the two support units. When disassembling, simply rotate the second connector 3 to switch it from the locked state to the plugged-in state to release the lock on the snap-fit ​​piece 21, so as to quickly complete the disassembly between the two support units. When this support unit is assembled outdoors, the first connector 2 and the second connector 3 located at both ends of the support rod 1 can quickly install and disassemble adjacent support rods 1 without the need to tighten multiple high-strength bolts, effectively reducing the difficulty of assembly and disassembly and improving the efficiency. Moreover, the snap-fit ​​part 21 and the second connector 3 can be manufactured together with the support rod 1, resulting in lower manufacturing costs. Each support rod 1 only needs to be equipped with one snap-fit ​​part 21 and one second connector 3, which can effectively reduce the overall assembly and disassembly costs. At the same time, since the snap-fit ​​part 21 is directly inserted into the second end of the support rod 1 and inserted into the second connector 3, on the one hand, the direction of the snap-fit ​​force generated during snap-fit ​​is close to or even coincides with the axis of the support rod 1, which is conducive to maintaining a uniform force at the connection point of adjacent support rods 1 after assembly, effectively ensuring that the axes of adjacent support rods 1 remain collinear, thereby improving the overall stability and connection strength after assembly. On the other hand, it also allows the snap-fit ​​structure to be completely contained inside the support rod 1, reducing exposed structures and improving the overall neatness.

[0050] Optionally, the second end of the support rod 1 has a mounting hole, and the second connector 3 includes a connecting cylinder 31. The connecting cylinder 31 is rotatably connected to the mounting hole and partially extends out of the mounting hole, and the side wall of the connecting cylinder 31 is provided with an insertion hole 311 for inserting the snap-fit ​​member 21. The wall of the insertion hole 311 is provided with a slide rail 312, and the snap-fit ​​member 21 slides into the slide rail 312 and snaps into and fixes itself to the connecting cylinder 31 when the connecting cylinder 31 rotates.

[0051] Specifically, a through hole is made in the side wall of the second end of the support rod 1 as a mounting hole, and the connecting cylinder 31 is inserted into the mounting hole. The length of the connecting cylinder 31 is greater than the diameter of the support rod 1, so that at least one end of the connecting cylinder 31 extends out of the mounting hole. A knob 32 or other structure can be provided at the end of the connecting cylinder 31 to facilitate the rotation of the connecting cylinder 31.

[0052] The connecting cylinder 31 has an insertion hole 311 at the mounting hole. A slide 312 is formed on the side wall of the insertion hole 311. The slide 312 extends circumferentially along the connecting cylinder 31. The diameter of the insertion hole 311 can be equal to or greater than the width of the slide 312. The width of the slide 312 can decrease from the side closer to the insertion hole 311 to the side farther away from the insertion hole 311, so that the snap-fit ​​21 can gradually abut against the side wall of the slide 312 when it is inserted into the slide 312, thereby forming an interference fit. The side wall of the slide 312 can also be set to be inclined towards the inside of the connecting cylinder 31 to better fit the snap-fit ​​21.

[0053] To further improve the locking effect, an elastic locking structure can be provided inside the connecting cylinder 31, such as an elastic locking rod extending along the axis of the connecting cylinder 31. When the locking member 21 slides into the slide rail 312, the elastic locking rod can be disengaged. After the locking member 21 slides to the designated position, the locking member 21 and the elastic locking structure are offset and can be pressed against the side of the locking member 21 near the insertion hole 311. The specific pressing method of the locking member 21 in the slide rail 312 can be designed according to the actual production and processing difficulty, and this utility model does not limit it in this way.

[0054] By opening mounting holes on the support rod 1, the connecting cylinder 31 can be pre-installed on the support rod 1 in advance, reducing on-site installation steps. By screwing the connecting cylinder 31 so that the insertion hole 311 faces the end face of the second end, the snap-fit ​​21 can be inserted into the insertion hole 311. Then, by rotating the connecting cylinder 31, the snap-fit ​​21 can slide into the slide rail 312 to form a snap-fit ​​fixation, thereby quickly fixing the snap-fit ​​21 and completing the assembly fixation quickly.

[0055] Optionally, the connecting cylinder 31 is provided with a locking hole 313, and the second connector 3 is provided with a locking part (not shown in the figure). In both the plugged-in state and the locked state, the locking part can be plugged into the locking hole 313.

[0056] Specifically, a locking hole 313 is provided on the outer wall of the connecting cylinder 31. Only one locking hole 313 can be provided, in which case two locking parts are provided. In the insertion and locking states, the locking hole 313 can correspond to one of the locking parts, allowing the locking part to be inserted into the locking hole 313 to lock the rotation of the connecting cylinder 31. Alternatively, two locking holes 313 can be provided, in which case only one locking part is needed. In the insertion and locking states, one of the two locking holes 313 corresponds to the locking part. The locking part can be located on the outside of the support rod 1 or on the wall of the mounting hole. The specific design depends on the location of the locking hole 313.

[0057] The locking part can be a structure with a certain elasticity and telescopic function, such as a glass bead or a spring pin, which can abut against the outer wall of the connecting cylinder 31. When the locking part corresponds to the locking hole 313, the elastic part returns to its original state and locks into the locking hole 313. The locking part can also be a structure with high rigidity, such as a plug rod. In this case, the plug rod is slidably connected to the support rod 1, and its head is pointed so that it can be inserted into the locking hole 313 when it corresponds to the locking hole 313. It can also lock the rotation of the connecting cylinder 31, and its tail can extend out of the second connector 3 to facilitate the removal of the plug rod from the locking hole 313.

[0058] By setting a locking part and a locking hole 313, after the connecting cylinder 31 switches states and rotates to the correct position, the locking part can form an insertion fit with the locking hole 313, thereby locking the connecting cylinder 31 and ensuring that the connecting cylinder 31 will not rotate due to accidental contact.

[0059] Optionally, the locking hole 313 corresponds to the wall of the mounting hole, and the locking part is elastically connected to the wall of the mounting hole.

[0060] Specifically, to facilitate the rotation of the connecting cylinder 31, the locking part preferably adopts an elastic structure such as a glass bead. It is fixed to the wall of the mounting hole and can abut against the outer wall of the connecting cylinder 31, causing compression deformation. When it aligns with the locking hole 313, the locking part at least has the ability to recover its deformation and insert into the locking groove. Thus, the connecting cylinder 31 only needs to overcome a certain amount of resistance during rotation, without requiring the operation of other structures, further simplifying the operation process.

[0061] Optionally, the outer wall of the connecting cylinder 31 has a limiting groove 314 extending circumferentially and corresponding to the wall of the mounting hole, and locking holes 313 are provided at both ends of the limiting groove 314.

[0062] Specifically, the locking part is at least partially located within the limiting groove 314, and the locking part slides and fits against the groove wall of the limiting groove 314. The side wall of the limiting groove 314 cooperates with the locking part to restrict the axial movement of the connecting cylinder 31, while the bottom wall of the limiting groove 314 can compress the locking part to cause it to undergo compressive deformation. A locking hole 313 is formed on the bottom wall of the limiting groove 314, and locking holes 313 are formed at both ends of the limiting groove 314. Therefore, only one locking part is needed. When the locking hole 313 corresponds to the locking part, the locking part will deform and insert into the locking hole 313 to form a snap-fit ​​fixation.

[0063] Reference Figures 7 to 9 Optionally, the snap-fit ​​component 21 includes a snap-fit ​​block 22. The snap-fit ​​block 22 is fixedly connected to the first connector 2, and the snap-fit ​​block 22 has a snap-fit ​​connector 23, which can be inserted into the second connector 3 and snap-fitted to the second connector 3.

[0064] Specifically, the snap-fit ​​block 22 can be fixedly connected to the first connector 2 by means of bonding, welding, bolting, or snap-fitting. A snap-fit ​​connector 23 protrudes from the side of the snap-fit ​​block 22 away from the support rod 1. The snap-fit ​​connector 23 can be spherical, cylindrical, or block-shaped, and can be inserted into the insertion hole 311 and slid into the slide rail 312 to form a snap-fit ​​fixation. In this embodiment, the snap-fit ​​connector 23 is cylindrical, and an annular groove 231 is provided in the middle of the snap-fit ​​connector 23. The annular groove 231 can be adapted to the slide rail 312 of the second connector 3, so that the head end of the snap-fit ​​connector 23 can snap onto the inner side of the connecting cylinder 31. The snap-fit ​​connector 23 can also abut against the side wall of the slide rail 312 and the inner wall of the connecting cylinder 31. The connection points can enter a locking state as the connecting cylinder 31 rotates, forming an interference fit, thereby achieving a stable snap-fit ​​of the snap-fit ​​connector 23.

[0065] Optionally, the support unit also includes a lifting cylinder 4. The lifting cylinder 4 is sleeved on and slidably connected to the first connector 2, and a snap-fit ​​member 21 is provided on the lifting cylinder 4.

[0066] Specifically, a lifting cylinder 4 is sleeved on the outside of the first connector 2. The lifting cylinder 4 can extend in a direction away from the support rod 1. The snap-fit ​​part 21 is inserted into the lifting cylinder 4 and fixedly connected to the lifting cylinder 4 by bolts, so as to facilitate disassembly for inspection and replacement.

[0067] By setting the lifting cylinder 4, the distance between the snap-fit ​​component 21 and the first connector 2 can be adjusted, thereby flexibly adjusting the distance between two adjacent support rods 1 to accommodate display devices of different sizes. To facilitate locking the lifting cylinder 4, a plug-in structure can be directly set to fix the lifting cylinder 4 to the first connector 2, or screws can be set on the lifting cylinder 4 and used to lock the lifting cylinder 4 by abutting against the first connector 2.

[0068] Optionally, the support unit further includes a fixing part 41. The fixing part 41 is inserted into the lifting cylinder 4 and at least partially inserted into the first connector 2 to fix the lifting cylinder 4.

[0069] Specifically, a connecting groove 24 is provided on the outer wall of the first connector 2, extending vertically. A countersunk hole is provided on the side of the lifting cylinder 4 near the support rod 1, and a fixing part 41 is inserted into the countersunk hole. The fixing part 41 can be a bolt, with the end of the bolt away from the head threaded into the fixing hole and extending into the connecting groove 24, and able to abut against the bottom wall of the connecting groove 24 to achieve locking. To improve the locking effect, multiple locking grooves 241 can be provided at intervals on the bottom wall of the connecting groove 24, allowing the end of the bolt away from the head to be inserted to form a snap-fit. At the same time, multiple fixing parts 41 can be distributed at intervals around the circumference of the lifting cylinder 4. The specific number of fixing parts 41 can be designed according to the actual size of the lifting cylinder 4, and this utility model does not limit it.

[0070] To ensure that the lifting cylinder 4 does not shift during sliding, a guide rod 42 is inserted through the side of the lifting cylinder 4 near the support rod 1, and the extension direction of the guide rod 42 is perpendicular to the axis of the lifting cylinder 4. A guide slide 25 is provided on the first connector 2, extending vertically, and the guide rod 42 is slidably connected within the guide slide 25. In this way, the lifting cylinder 4 can drive the guide rod 42 to slide within the guide slide 25 during sliding, effectively limiting the sliding direction of the lifting cylinder 4 and ensuring that the lifting cylinder 4 does not tilt.

[0071] Reference Figure 1 Optionally, the support unit further includes a connecting rod 5 and a telescopic rod 6. One end of the connecting rod 5 is connected to the support rod 1, and the other end is hinged to a first fixing block 51 that is fixedly connected to the display device; one end of the telescopic rod 6 is connected to the support rod 1, and the other end is telescopic relative to the support rod 1 and is hinged to a second fixing block 61 that is fixedly connected to the display device.

[0072] Specifically, the connecting rod 5 and the telescopic rod 6 form a set of connecting components. Multiple connecting components can be spaced apart along the axial direction of the support rod 1 to improve the connection strength with the display device. One end of the connecting rod 5 can be welded to the support rod 1, and the other end is connected to the first fixing block 51 through a hinge or pivot. One end of the telescopic rod 6 can be rotatably connected to the support rod 1 through a hinge or pivot, and the telescopic rod 6 can extend and retract away from the connecting rod 5. A second fixing block 61 can be connected to the telescopic end of the telescopic rod 6 through a hinge or pivot. Both the first fixing block 51 and the second fixing block 61 can be fixedly connected to the display device by means of screws or snap-fit.

[0073] By setting up connecting rod 5 and telescopic rod 6, when it is necessary to connect with the display device, the telescopic rod 6 can be rotated and its length adjusted according to the type and size of the display device, thereby changing the relative position between the first fixing block 51 and the second fixing block 61, so that each support unit can form a fixed connection with different types of display devices.

[0074] Reference Figure 10 The windproof frame is used to fix the display device. It includes multiple support units, which are spliced ​​and fixedly connected to the display device in sequence.

[0075] By quickly splicing and fixing multiple support units, the entire windproof frame can be assembled and fixed quickly, facilitating the rapid installation and disassembly of the display device, thereby effectively reducing the overall assembly and disassembly difficulty and improving assembly and disassembly efficiency.
