[0002] Dome tents are widely used in various temporary buildings, outdoor activities, exhibitions, storage and other occasions due to their stable structure, strong wind resistance and convenient use. During the assembly and disassembly of the tent, the connection and flipping functions of the beams are crucial.

[0003] In the existing dome tent designs, the beams are generally connected by fixing methods such as pins and buckles. However, when it is necessary to quickly set up and disassemble the tent in windy and rainy weather, it is necessary to manually fix and unlock each connection point, and the operation process is cumbersome and complex, which is not conducive to personnel use. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an adaptive locking device for a beam flipping connection assembly of a dome tent.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An adaptive locking device for a beam flipping connection assembly of a dome tent, including a tent support. At the top of the tent support, two beams are symmetrically and fixedly installed. Between the two beams, a plurality of arc-shaped top rods are equidistantly arranged. On the outer surfaces of the two beams, multiple groups of C-shaped card seats are arranged in pairs. One group of two C-shaped card seats is symmetrically arranged on the outer surfaces of the two beams. The C-shaped card seats are sleeved on the outer surfaces of the beams and slidably installed thereon. At the mutually remote ends of one group of two C-shaped card seats, support plates are fixedly installed. On the outer surface of one side of the support plate, a rotating sleeve is rotatably installed. At one end of the rotating sleeve, a U-shaped block is fixedly installed. On the outer surface of the U-shaped block, a U-shaped groove is formed. The end of the arc-shaped top rod is arranged inside the U-shaped groove. On the inner walls of the opposite sides of the U-shaped groove, two slots are symmetrically opened. On the outer surfaces of the opposite sides of the end of the arc-shaped top rod, two insertion blocks are symmetrically and fixedly installed. The two insertion blocks are respectively slidably installed on the inner walls of the two slots.

[0007] As a further solution of the present invention, a clamping plate is slidably installed on the inner wall of the U-shaped groove. At the top of the clamping plate, an inclined clamping strip is provided. The inclined clamping strip protrudes from the outer surface of the clamping plate. The lower surface of the inclined clamping strip abuts against the outer surface of the end of the arc-shaped top rod. The outer surface of the clamping plate on the side close to the arc-shaped top rod is higher than the inner wall of one side of the slot.

[0008] As a further solution of the present invention, a third hexagonal column is fixedly installed on the outer surface of the other side of the card board. A second spring is sleeved on the outer surface of the third hexagonal column. One end of the second spring is fixedly connected to the outer surface of the other side of the card board, and the other end of the second spring is fixedly connected to the inner wall of one end of the U-shaped groove.

[0009] As a further solution of the present invention, the other end of the third hexagonal column penetrates through the end face of the rotating sleeve and is fixedly installed with a positioning rod. A groove matching the positioning rod is opened on the outer surface of the rotating sleeve where the other end penetrates through the support plate. A groove of the same kind is opened on the outer surface of the support plate close to the positioning rod. The positioning rod is arranged inside the groove. A crescent plate is rotatably installed on the outer surface of the support plate close to the positioning rod. A positioning notch matching the positioning rod is opened on the outer surface of the crescent plate.

[0010] As a further solution of the present invention, a first hexagonal column is slidably inserted into the inner wall of the C-shaped card seat away from the support plate. A limiting clamping plate is fixedly installed at one end of the first hexagonal column. A V-shaped opening is opened on the outer surface of the limiting clamping plate opposite to the first hexagonal column. The other end of the first hexagonal column penetrates through the outer surface of the C-shaped card seat and is fixedly installed with a first sliding plate. A sliding cylinder is fixedly installed on the outer surface of the C-shaped card seat close to the first sliding plate. The first sliding plate is slidably installed with the inner wall of the sliding cylinder.

[0011] As a further solution of the present invention, a second sliding plate is also slidably installed in the inner wall of the sliding cylinder. A first spring is arranged between the second sliding plate and the first sliding plate. One end of the first spring is fixedly connected to the outer surface of the second sliding plate, and the other end of the first spring is fixedly connected to the outer surface of the first sliding plate. A second hexagonal column is fixedly installed on the outer surface of the other side of the second sliding plate. The other end of the second hexagonal column penetrates through the outer surface of the sliding cylinder and is fixedly installed with a connecting plate.

[0012] As a further solution of the present invention, an extrusion block is fixedly installed at the other end of the connecting plate. The extrusion block is arranged perpendicular to the connecting plate. An inclined surface is arranged on the outer surface of the extrusion block. An arc block is fixedly installed on the end face of the U-shaped block close to the connecting plate. An arc inclined groove is opened on the outer surface of the arc block. The inclined surface abuts against the inner wall of the arc inclined groove. An inclined surface matching the inclined surface is arranged on the inner wall of the arc inclined groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The U-shaped block drives the positioning rod to rotate through the rotating sleeve and the third hexagonal column. The positioning rod abuts against the inner arc surface of the crescent plate through its top end. When the positioning rod rotates, it lifts the crescent plate. When the positioning rod rotates to the position of the positioning notch, the crescent plate will rotate downward under the action of gravity. At this time, the positioning notch is clamped with the positioning rod. After the arc-shaped ejector rod rotates upward by 90° through this device, its position is limited, making the position of the arc-shaped ejector rod easy to fix. The fixing process is simple and easy to operate, facilitating the operation of the user;

[0015] 2. The extrusion block drives the second hexagonal column to move closer to the C-shaped card seat through the connecting plate. The second hexagonal column drives the first slide plate to move closer to the C-shaped card seat through the second slide plate and the first spring. The first slide plate drives the limit clamping plate to abut against the outer surface of the cross beam through the first hexagonal column. The surface of the limit clamping plate is provided with anti-slip protrusions. When the limit clamping plate abuts against the outer surface of the cross beam, it can prevent the C-shaped card seat from sliding along the outer surface of the cross beam. Through this device, it is convenient to limit the position of the arc-shaped ejector rod on the cross beam and prevent it from sliding randomly during use, affecting the erection of the tent.

[0029] Refer to Figures 1 - 9, an adaptive locking device for the flipping connection assembly of the crossbeam of a dome tent, comprising a tent bracket 1. Two crossbeams 2 are symmetrically and fixedly installed at the top of the tent bracket 1. A plurality of arc-shaped top rods 3 are equidistantly arranged between the two crossbeams 2. A plurality of groups of C-shaped card seats 4 are arranged in pairs on the outer surfaces of the two crossbeams 2. Two C-shaped card seats 4 in a group are symmetrically arranged on the outer surfaces of the two crossbeams 2. The C-shaped card seats 4 are sleeved on the outer surfaces of the crossbeams 2 and are slidably installed thereon. Support plates 401 are fixedly installed at the mutually remote ends of two C-shaped card seats 4 in a group. A rotating sleeve 15 is rotatably installed on the outer surface of one side of the support plate 401. A U-shaped block 11 is fixedly installed at one end of the rotating sleeve 15. A U-shaped groove 1101 is formed on the outer surface of the U-shaped block 11. The end of the arc-shaped top rod 3 is arranged inside the U-shaped groove 1101. Two slots 1102 are symmetrically formed on the inner walls of the two opposite sides of the U-shaped groove 1101. Two insertion blocks 301 are symmetrically and fixedly installed on the outer surfaces of the two opposite sides of the end of the arc-shaped top rod 3. The two insertion blocks 301 are respectively slidably installed on the inner walls of the two slots 1102. The other end of the third hexagonal column 1201 penetrates through the end face of the rotating sleeve 15 and is fixedly installed with a positioning rod 14. A groove matching the positioning rod 14 is formed on the outer surface of the other end of the rotating sleeve 15 through which the positioning rod 14 penetrates. A groove identical to that is formed on the outer surface of the support plate 401 close to the positioning rod 14. The positioning rod 14 is arranged inside the groove. A crescent plate 16 is rotatably installed on the outer surface of the support plate 401 close to the positioning rod 14. A positioning notch 1601 matching the positioning rod 14 is formed on the outer surface of the crescent plate 16.

[0030] The U-shaped block 11 drives the positioning rod 14 to rotate through the rotating sleeve 15 and the third hexagonal column 1201. The top end of the positioning rod 14 abuts against the arc surface of the inner ring of the crescent plate 16. When the positioning rod 14 rotates, the crescent plate 16 is lifted up. When the positioning rod 14 rotates to the position of the positioning notch 1601, the crescent plate 16 will rotate downward under the action of gravity. At this time, the positioning notch 1601 is clamped with the positioning rod 14. Through this device, after the arc-shaped top rod 3 rotates upward by 90°, its position is limited, so that the position of the arc-shaped top rod 3 is convenient to fix. The fixing process is simple and easy to operate, which is convenient for the user to operate.

[0031] In this embodiment, a clamping plate 12 is slidably installed on the inner wall of the U-shaped groove 1101. An inclined clamping strip 1202 is arranged at the top end of the clamping plate 12. The inclined clamping strip 1202 protrudes from the outer surface of the clamping plate 12. The lower surface of the inclined clamping strip 1202 abuts against the outer surface of the end of the arc-shaped top rod 3. The outer surface of the clamping plate 12 close to the arc-shaped top rod 3 is higher than the inner wall of one side of the slot 1102. A third hexagonal column 1201 is fixedly installed on the outer surface of the other side of the clamping plate 12. A second spring 13 is sleeved on the outer surface of the third hexagonal column 1201. One end of the second spring 13 is fixedly connected to the outer surface of the other side of the clamping plate 12, and the other end of the second spring 13 is fixedly connected to the inner wall of one end of the U-shaped groove 1101.

[0032] The user then inserts the two ends of the arc ejector rod 3 into the U-shaped grooves 1101 inside the U-shaped block 11 respectively, so that the insertion block 301 is inserted into the slot 1102. When the end face of the arc ejector rod 3 just inserts into the U-shaped groove 1101, it will abut against the inclined card strip 1202 on the clamping plate 12. When the arc ejector rod 3 completely slides into the U-shaped groove 1101, the lower surface of the inclined card strip 1202 abuts against the outer surface of the arc ejector rod 3. Through this device, it is convenient to quickly fix the U-shaped block 11 to the end of the arc ejector rod 3, facilitating subsequent rapid assembly.

[0033] In this embodiment, a first hexagonal column 502 is slidably inserted into the inner wall on the side of the C-shaped card seat 4 away from the support plate 401. One end of the first hexagonal column 502 is fixedly installed with a limit clamping plate 5. A V-shaped opening 501 is formed on the outer surface of the limit clamping plate 5 on the side opposite to the first hexagonal column 502. The other end of the first hexagonal column 502 penetrates through the outer surface of the C-shaped card seat 4 and is fixedly installed with a first sliding plate 503. A sliding cylinder 6 is fixedly installed on the outer surface of the C-shaped card seat 4 close to the first sliding plate 503. The first sliding plate 503 is slidably installed with the inner wall of the sliding cylinder 6. A second sliding plate 701 is also slidably installed on the inner wall of the sliding cylinder 6. A first spring 504 is arranged between the second sliding plate 701 and the first sliding plate 503. One end of the first spring 504 is fixedly connected to the outer surface of the second sliding plate 701, and the other end of the first spring 504 is fixedly connected to the outer surface of the first sliding plate 503. A second hexagonal column 7 is fixedly installed on the outer surface of the other side of the second sliding plate 701. The other end of the second hexagonal column 7 penetrates through the outer surface of the sliding cylinder 6 and is fixedly installed with a connecting plate 8. The other end of the connecting plate 8 is fixedly installed with an extrusion block 9. The extrusion block 9 is arranged perpendicular to the connecting plate 8. An inclined surface 901 is arranged on the outer surface of the extrusion block 9. An arc block 10 is fixedly installed on the end face of the U-shaped block 11 close to the connecting plate 8. An arc inclined groove 101 is formed on the outer surface of the arc block 10. The inclined surface 901 abuts against the inner wall of the arc inclined groove 101, and an inclined surface matching the inclined surface 901 is arranged on the inner wall of the arc inclined groove 101.

[0034] When the U-shaped block 11 rotates 90°, the arc inclined groove 101 on the arc block 10 will abut against the extrusion block 9, so that the inclined surface on the arc inclined groove 101 abuts against the inclined surface 901. Through the continuous rotation of the arc block 10, the extrusion block 9 drives the second hexagonal column 7 to move close to the C-shaped card seat 4 through the connecting plate 8. The second hexagonal column 7 drives the first sliding plate 503 to move close to the C-shaped card seat 4 through the second sliding plate 701 and the first spring 504. The first sliding plate 503 drives the limit clamping plate 5 to abut against the outer surface of the cross beam 2 through the first hexagonal column 502. Anti-slip protrusions are arranged on the surface of the limit clamping plate 5. When the limit clamping plate 5 abuts against the outer surface of the cross beam 2, it can prevent the C-shaped card seat 4 from sliding along the outer surface of the cross beam 2. Through this device, it is convenient to limit the position of the arc ejector rod 3 on the cross beam 2, preventing it from sliding randomly during use and affecting the erection of the tent.

[0035] It should be noted that when the present invention is in use, the user first manually fixes the cross beam 2 to the tent bracket 1 through the fixing bolts;

[0036] Then, the user inserts the two ends of the arc top rod 3 into the U-shaped grooves 1101 inside the U-shaped blocks 11 respectively, so that the insertion blocks 301 are inserted into the slots 1102. When the end face of the arc top rod 3 just inserts into the U-shaped groove 1101, it will abut against the inclined clamping strips 1202 on the clamping plate 12. When the arc top rod 3 completely slides into the U-shaped groove 1101, the lower surface of the inclined clamping strip 1202 abuts against the outer surface of the arc top rod 3. Through this device, it is convenient to quickly fix the U-shaped block 11 to the end of the arc top rod 3, facilitating subsequent rapid assembly;

[0037] As the arc top rod 3 continues to slide in, the clamping plate 12 will be pushed out. The clamping plate 12 drives the positioning rod 14 to slide out of the groove through the third hexagonal column 1201. At this time, the U-shaped block 11 is released from the limit and can rotate. By pushing the arc top rod 3 to rotate upward by 90°, the arc top rod 3 drives the U-shaped block 11 to rotate by 90°. At this time, the U-shaped block 11 drives the positioning rod 14 to rotate through the rotating sleeve 15 and the third hexagonal column 1201. The positioning rod 14 abuts against the arc surface of the inner ring of the crescent plate 16 through the top end. When the positioning rod 14 rotates, the crescent plate 16 is pushed up. When the positioning rod 14 rotates to the position of the positioning notch 1601, the crescent plate 16 will rotate downward under the action of gravity. At this time, the positioning notch 1601 is clamped with the positioning rod 14. Through this device, after the arc top rod 3 rotates upward by 90°, its position is limited, making the position of the arc top rod 3 easy to fix. The fixing process is simple and easy to operate, facilitating the operation of the user;

[0038] When the U-shaped block 11 rotates by 90°, the arc-shaped inclined groove 101 on the arc block 10 will abut against the extrusion block 9, so that the inclined surface on the arc-shaped inclined groove 101 abuts against the inclined surface 901. Through the continuous rotation of the arc block 10, the extrusion block 9 drives the second hexagonal column 7 to move closer to the C-shaped card seat 4 through the connecting plate 8. The second hexagonal column 7 drives the first sliding plate 503 to move closer to the C-shaped card seat 4 through the second sliding plate 701 and the first spring 504. The first sliding plate 503 drives the limiting clamping plate 5 to abut against the outer surface of the cross beam 2 through the first hexagonal column 502. The surface of the limiting clamping plate 5 is provided with anti-slip protrusions. When the limiting clamping plate 5 abuts against the outer surface of the cross beam 2, it can prevent the C-shaped card seat 4 from sliding along the outer surface of the cross beam 2. Through this device, it is convenient to limit the position of the arc top rod 3 on the cross beam 2 and prevent it from sliding randomly during use, affecting the erection of the tent;

[0039] Through the setting of the first spring 504, the C-type card holder 4 can be used under crossbeams 2 of different sizes. And through the setting of the V-shaped opening 501, it can also be used when the outer surface of the crossbeam 2 is an arc surface. With this device, it can adapt to crossbeams 2 of various sizes and shapes, improving the applicability of the device.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
