Technical Field
[0001] This utility model relates to the field of billboard frame technology, specifically a quick-installation outdoor billboard frame structure. Background Technology
[0002] As a crucial structure for displaying advertising content, billboard frames play a vital role in the advertising industry. They not only convey advertising information but also directly impact brand image and marketing effectiveness. Generally, outdoor billboard frames consist of steel columns, beams, and skeletons, which are connected by welding or bolts to form a stable structural system.
[0003] Traditional outdoor billboard frames are mostly assembled using bolt fastening. Each bolt needs to be tightened individually, which takes a long time to install and makes disassembly difficult during later maintenance or replacement. This is especially true for high-altitude operations, which not only increases construction costs but also poses safety hazards.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a quick-installation outdoor billboard frame structure. Utility Model Content
[0005] The purpose of this utility model is to provide a quick-installation outdoor billboard frame structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation outdoor billboard frame structure, including a supporting crossbar and a limiting component. Dovetail blocks are fixed to both sides of the bottom of the supporting crossbar. Supporting vertical rods 1 and 2 are respectively connected to the outside of the two dovetail blocks. Dovetail grooves are provided at the top and bottom of both supporting vertical rods 1 and 2. Additional crossbars are provided on the right side of supporting vertical rod 1 and the left side of supporting vertical rod 2. Grooves are provided on both supporting crossbar 1 and the additional crossbars. Mounting holes are provided on the surfaces of both supporting vertical rods 1 and 2. The limiting component penetrates the mounting hole. The limiting assembly includes a limiting cylinder, a sliding groove, a fixed seat, a limiting clamping rod, a base block, a sliding seat, a return spring, a first support arm, a second support arm, and a locking block. The outer surface of the limiting cylinder has a sliding groove, and a fixed seat is fixedly fixed through the middle of the limiting cylinder. A limiting clamping rod is inserted through the through hole in the middle of the fixed seat, and the two ends of the limiting clamping rod are respectively connected to the base block and the sliding seat. A return spring is provided at the other end of the sliding seat, and the two ends of the sliding seat are hinged to the second support arm by a pin. The two ends of the fixed seat are hinged to the first support arm by a pin, and the other end of the first support arm is hinged to the locking block by a pin.
[0007] Furthermore, the first and second supporting vertical rods are parallel to each other, and the first supporting horizontal rod and the first supporting vertical rod are perpendicular to each other.
[0008] Furthermore, dovetail blocks are connected to the dovetail grooves at the bottom of both the first and second support rods, and a second support crossbar is fixed to the bottom of the dovetail blocks.
[0009] Furthermore, the ratio of the number of dovetail block one, dovetail groove and dovetail block two is 2:4:2, and the dovetail groove is adapted to dovetail block one and dovetail block two.
[0010] Furthermore, grooves are also provided on both sides of the top of the second support crossbar, and the number of grooves and the number of locking blocks are the same.
[0011] Furthermore, the limiting component is provided in four sets, and the number of mounting holes is the same as the number of limiting components. The diameter of the mounting holes is adapted to the outer diameter of the limiting cylinder.
[0012] Furthermore, the limiting clamping rod, the base block, and the sliding seat are integrated into one structure, and the sliding seat is elastically connected to the limiting cylinder through a return spring.
[0013] This utility model provides a quick-installation outdoor billboard frame structure, which has the following advantages:
[0014] 1. In this utility model, the dovetail blocks on both sides of the bottom of the first support crossbar are inserted into the dovetail grooves at the top of the first and second support vertical bars, respectively. Similarly, the dovetail blocks on both sides of the top of the second support crossbar are inserted into the dovetail grooves at the bottom of the first and second support vertical bars, respectively. This allows the first, second, and third support crossbars to collectively form a rectangular frame body. Through the guiding connection of the dovetail blocks and the dovetail grooves, the traditional bolt connection's step-by-step tightening is eliminated, effectively improving installation efficiency and enhancing connection stability. Furthermore, the frame can be disassembled into independent components, allowing for layered stacking during transportation and saving logistics space.
[0015] 2. After the main frame of this utility model is assembled, the limiting cylinder is inserted through the mounting hole, and then the base block is pressed to move the limiting clamping rod and the sliding seat into the limiting cylinder, compressing the return spring. At this time, support arm one and support arm two are folded, and the locking block is retracted. After aligning the locking block with the groove, the base block is released, and the return spring rebounds to reset the sliding seat. The support arm one is pushed to rotate around the fixed seat by the support arm two at both ends of the sliding seat, so that the locking block extends along the slide groove and accurately locks into the groove of support crossbar one, support crossbar two and additional crossbar, realizing the rigid connection between the vertical bar and the horizontal bar, preventing the frame from loosening, improving the overall stability, enhancing the wind resistance, and allowing for quick fixing and unlocking without tools, greatly improving the efficiency of installation and disassembly.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figure 1 and Figure 4 As shown, a quick-installation outdoor billboard frame structure includes a support crossbar 1 and a limiting component 11. Dovetail blocks 2 are fixed on both sides of the bottom of the support crossbar 1. Supporting vertical rods 3 and 4 are respectively connected to the outside of the two dovetail blocks 2. Dovetail grooves 5 are opened at the top and bottom of the supporting vertical rods 3 and 4. The supporting vertical rods 3 and 4 are parallel to each other, and the support crossbar 1 and 3 are perpendicular to each other. Dovetail blocks 6 are connected in the dovetail grooves 5 at the bottom of the supporting vertical rods 3 and 4. Supporting crossbars 7 are fixed at the bottom of the dovetail blocks 6. The ratio of the number of dovetail blocks 12, dovetail grooves 5 and dovetail blocks 26 is 2:4:2, and the dovetail grooves 5 are all adapted to the dovetail blocks 12 and 26.
[0023] The specific operation is as follows: insert the dovetail blocks 2 on both sides of the bottom of the support crossbar 1 into the dovetail grooves 5 at the top of the support vertical bar 3 and the support vertical bar 4, respectively. Insert the dovetail blocks 6 on both sides of the top of the support crossbar 7 into the dovetail grooves 5 at the bottom of the support vertical bar 3 and the support vertical bar 4, respectively. This makes the support crossbar 1, support vertical bar 3, support vertical bar 4 and support crossbar 7 together form the main body of the rectangular frame. Through the guide connection of the dovetail blocks 2, dovetail blocks 6 and dovetail grooves 5, the traditional bolt connection of tightening each one is eliminated, which effectively improves the installation efficiency and enhances the connection stability. Moreover, the frame can be disassembled into independent parts and can be stacked in layers during transportation, saving logistics space.
[0024] like Figures 1 to 4 As shown, additional crossbars 8 are provided on the right side of support vertical rod 1 3 and the left side of support vertical rod 2 4. Grooves 9 are provided on both support crossbar 1 1 and additional crossbars 8. Mounting holes 10 are provided on the surfaces of support vertical rod 1 3 and support vertical rod 2 4. A limiting component 11 passes through the mounting hole 10. The limiting component 11 includes a limiting cylinder 1101, a sliding groove 1102, a fixed seat 1103, a limiting clamping rod 1104, a base block 1105, a sliding seat 1106, a return spring 1107, a support arm 1108, a support arm 2 1109, and a locking block 1110. A sliding groove 1102 is provided on the outer surface of the limiting cylinder 1101, and a fixed seat 1103 is fixedly inserted through the middle of the limiting cylinder 1101. A limiting clamping rod 1104 passes through the through hole in the middle of the fixed seat 1103, and both ends of the limiting clamping rod 1104 are connected to the base block 1105. The base block 1105 and the sliding seat 1106 are provided. The other end of the sliding seat 1106 is provided with a return spring 1107. Both ends of the sliding seat 1106 are hinged to the second support arm 1109 by a pin. Both ends of the fixed seat 1103 are hinged to the first support arm 1108 by a pin. The other end of the first support arm 1108 is hinged to the locking block 1110 by a pin. The top two sides of the second support rod 7 are also provided with grooves 9. The number of grooves 9 and locking blocks 1110 is the same. The limiting component 11 is provided with four sets. The number of mounting holes 10 and limiting components 11 is the same. The diameter of the mounting holes 10 is adapted to the outer diameter of the limiting cylinder 1101. The limiting clamping rod 1104, the base block 1105 and the sliding seat 1106 are integrated. The sliding seat 1106 is elastically connected to the limiting cylinder 1101 by the return spring 1107.
[0025] The specific operation is as follows: After the main frame is assembled, the limiting cylinder 1101 is inserted through the mounting hole 10, and then the base block 1105 is pressed, causing the limiting clamping rod 1104 and the sliding seat 1106 to move into the limiting cylinder 1101, compressing the return spring 1107. At this time, the first support arm 1108 and the second support arm 1109 are folded, and the locking block 1110 is retracted. After aligning the locking block 1110 with the groove 9, the base block 1105 is released, and the return spring 1107 rebounds, causing the sliding seat 1106 to retract. 106 Reset: The support arm 1108 is pushed to rotate around the fixed seat 1103 by the support arm 2 1109 at both ends of the sliding seat 1106, so that the locking block 1110 extends along the slide groove 1102 and is precisely locked into the groove 9 of the support crossbar 1, support crossbar 2 7 and the additional crossbar 8, so as to realize the rigid connection between the vertical bar and the horizontal bar, avoid the frame from loosening, improve the overall stability, enhance the wind resistance, and can quickly complete the fixing and unlocking without tools, greatly improving the installation and disassembly efficiency.
[0026] In summary, when using this quick-assembly outdoor billboard frame structure, the first step is to assemble it by aligning the dovetail blocks 2 on both sides of the bottom of the support crossbar 1 with the dovetail grooves 5 at the top of the support vertical bar 3 and the support vertical bar 4, so that the support crossbar 1 is perpendicularly connected to the support vertical bar 3 and the support vertical bar 4. Then, the dovetail blocks 26 at the top of the support crossbar 7 are inserted into the dovetail grooves 5 at the bottom of the support vertical bar 3 and the support vertical bar 4, forming a rectangular frame body. At this point, the support vertical bar 3 and the support vertical bar 4 are tightly engaged with the support crossbar 1 and the support crossbar 7 through the dovetail structure, thus initially achieving positioning.
[0027] After the main frame is assembled, the limiting cylinders 1101 of the four sets of limiting components 11 pass through the mounting holes 10 on the surfaces of the first support rod 3 and the second support rod 4 respectively. Then, press the base block 1105, which will drive the limiting clamping rod 1104 and the sliding seat 1106 to move into the limiting cylinder 1101, so that the return spring 1107 is compressed, the first support arm 1108 and the second support arm 1109 are folded, and the locking block 1110 moves towards each other.
[0028] Subsequently, after adjusting the locking blocks 1110 to correspond one-to-one with the grooves 9, the base block 1105 is released. The return spring 1107 rebounds, driving the limit clamping rod 1104 and the sliding seat 1106 to reset. This causes the support arms 1109 at both ends of the sliding seat 1106 to push the support arm 1108 to rotate around the fixed seat 1103, causing the locking blocks 1110 to move in opposite directions. Finally, they are locked into the grooves 9 of the support crossbar 1, support crossbar 2, and additional crossbar 8, completing the rigid locking of the vertical and horizontal bars. This ensures the connection strength of the billboard frame. Moreover, the tool-free design allows for single-person operation. During disassembly, only pressing the base block 1105 is needed to unlock the frame, greatly improving the efficiency of frame disassembly. This is suitable for outdoor high-altitude operations and reduces construction time and safety risks.
