DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The utility model provides a technical solution: Figure 1-4 The utility model discloses a parade colored flag suitable for folk activities, comprising a flag 1 and a flagpole 2. A support rod 6 is provided at the top of the flag 1, and the support rod 6 is connected to the flagpole 2 through a connecting piece 3. A winding mechanism 4 is provided inside the support rod 6, and the winding mechanism 4 includes a rotating shaft 43. A storage groove 41 is provided at the middle position inside the support rod 6. A through hole 42 is provided on the bottom side of the support rod 6, and the interior of the through hole 42 is communicated with the interior of the storage groove 41. The rotating shaft 43 is rotatably installed in the storage groove 41. The top of the flag 1 passes through the through hole 42 and is fixedly connected to the outer peripheral wall of the rotating shaft 43. A driving member 44 is provided at both ends of the support rod 6, and an exhaust mechanism 5 is provided at both ends of the support rod 6.

[0021] In this embodiment, after use, the improved folk activity parade flag can be driven by the driving member 44 to rotate the rotating shaft 43, so that the flag 1 is gradually rolled up on the outer bearing of the rotating shaft 43, and finally the flag 1 is rolled up into the storage tank 41, and the through hole 42 is automatically closed. Subsequently, the driving member 44 cooperates with the exhaust mechanism 5 to extract part of the gas in the storage tank 41, so that the flag 1 is stored in a relatively closed and vacuum-like environment, and the parade flag can be split into two rod-shaped components through the connecting member 3.

[0022] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the connecting member 3 includes a collar 31, which is fixedly sleeved on the outer peripheral side of the flagpole 2 by bolts, and the collar 31 is fixedly connected to the support rod 6, so that the collar can be adjusted to a suitable position on the flagpole as needed;

[0023] In this embodiment, when assembling the flagpole 2 and the flag 1, the operator inserts the flagpole 2 into the collar 31. Due to the mutual interference between the inner ring wall of the collar 31 and the flagpole 2, the support rod 6 and the flagpole 2 are in a cross state and move along a linear trajectory along the flagpole 2. Then the operator screws the bolt into the flagpole 2, thereby locking the position of the collar 31 and the flagpole 2 and keeping the position of the support rod 6 on the flagpole 2 unchanged.

[0024] In a further preferred embodiment of the present invention, Figure 3 As shown, two limit strips 32 are arranged between the collar 31 and the support rod 6, and both ends of each limit strip 32 are respectively fixedly connected to the support rod 6 and the collar 31, and the limit strip 32 is arranged obliquely;

[0025] In this embodiment, after the flagpole 2 and the support rod 6 are assembled, the limit strip 32, the support rod 6 and the ring 31 cooperate with each other to form two triangular support structures between the support rod 6 and the flagpole 2, thereby enhancing the connection strength between the flagpole 2 and the support rod 6.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, a soft strip 45 is fixedly mounted on the bottom side of the flag 1, and the cross-sectional shape of the soft strip 45 is the same as the cross-sectional shape of the through hole 42;

[0027] In this embodiment, after the flag 1 is rolled into the storage slot 41 , the soft strip 45 can be pulled together to be inserted into the through hole 42 , and at the same time, the soft strip 45 fits tightly against the inner wall of the through hole 42 , thereby automatically blocking the opening of the through hole 42 , so that a closed space is formed in the storage slot 41 .

[0028] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the exhaust mechanism 5 includes two piston plates 52, and circular grooves 51 with a T-shaped cross-section are provided at both ends of the support rod 6. The piston plates 52 are arranged in the corresponding circular grooves 51, and the outer peripheral wall of the piston plate 52 contacts the inner wall of the corresponding circular groove 51. A plurality of first one-way valves 53 are relatively fixedly installed in the support rod 6, and the two ends of each first one-way valve 53 are respectively inserted into the storage groove 41 and the corresponding circular groove 51, and a plurality of second one-way valves 54 are relatively fixedly penetrated on the piston plate 52;

[0029] In this embodiment, after the flag 1 is rolled up, the operator pulls the piston plate 52 to move back and forth in the circular groove 51 through the driving member 44. When the piston plate 52 moves toward the opening of the circular groove 51, the gas in the circular groove 51 can be pushed out from the gap between the round rod 442 and the circular groove 51. At the same time, the space between the piston plate 52 and the inner bottom wall of the circular groove 51 is gradually expanded, and a negative pressure cavity is formed between the piston plate 52 and the first one-way valve 53, and a sufficient pressure difference is generated at both ends of the first one-way valve 53, so that part of the gas in the storage tank 41 gradually flows into the circular groove 51. When the piston plate 52 moves in the direction away from the opening of the circular groove 51, the gas in the circular groove 51 will not flow back into the storage groove 41 due to the obstruction of the first one-way valve 53, and the movement of the piston plate 52 causes the space between the piston plate 52 and the first one-way valve 53 to gradually shrink, and the gas between the piston plate 52 and the first one-way valve 53 is pressed into the second one-way valve 53, and the second one-way valve 53 passes through the piston plate 52. According to the above repetition, most of the gas in the storage groove 41 can be gradually extracted, and the strength of the negative pressure in the storage groove 41 can be judged according to the resistance when the piston plate 52 is pulled.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, the driving member 44 includes two caps 441, which are threadedly sleeved on the two ends of the support rod 6, and a round rod 442 is fixedly penetrated at the center position of the piston plate 52, and the outer peripheral wall of the round rod 442 is gap-matched with the inner wall of the corresponding circular groove 51, one end of the round rod 442 is fixedly connected to the corresponding cap 441, and the other end of the round rod 442 is in contact with the inner wall of the corresponding circular groove 51, and a hexagonal rod 443 is slidably installed in the two round rods 442, and the opposite ends of the two hexagonal rods 443 extend to the outside of the corresponding round rod 442 and are respectively fixedly connected to the two ends of the rotating shaft 43;

[0031] In this embodiment, the distance between the sleeve and the hexagonal rod 443 can be adjusted by sliding the hexagonal rod 443 inside the round rod 442, so that the sleeve can be unscrewed from the support rod 6, and due to the mutual interference between the hexagonal rod 443 and the round rod 442, the operator can rotate the sleeve to drive the rotating shaft 43 to rotate together, and at the same time, the operator can pull the round rod 442 back and forth through the sleeve, thereby pulling the piston plate 52 inside the circular hole to move back and forth.

[0032] Working principle: When the improved folk parade colored flag is used, the operator passes the bottom of the flagpole 2 through the collar 31. Due to the mutual interference between the inner ring wall of the collar 31 and the flagpole 2, the support rod 6 and the flagpole 2 are in a cross-shaped state and move along the flagpole 2 in a linear track. After adjusting the collar 31 to a suitable position on the flagpole 2, the operator screws the bolt into the flagpole 2, thereby locking the collar 31 and the flagpole 2, and keeping the support rod 6 on the flagpole 2 unchanged;

[0033] After the support rod 6 and the flagpole 2 are assembled, the operator rotates the sleeve in the opposite direction to unscrew the sleeve from the support rod 6, and then the operator buckles the soft strip 45 out of the through hole 42. Due to the bending deformation of the soft strip 45, a gap is generated between the soft strip 45 and the inner wall of the through hole 42. At this time, the external gas flows into the storage tank 41 through the gap, thereby relieving the negative pressure state in the storage tank 41. Then, the operator pulls the flag 1 through the soft strip 45. As the rotating shaft 43 rotates, the flag 1 is gradually pulled out of the storage tank 41. Due to the support of the rotating shaft 43 and the soft strip 45 on the flag 1, the flag 1 remains in a relatively stable straight state. Finally, the operator screws the sleeve onto the support rod 6 again, and the assembly of the parade flag is completed.

[0034] After the improved folk parade colored flag is used, the operator unscrews the bolt in the flagpole 2 to release the locking state between the collar 31 and the flagpole 2, then pulls the flagpole 2 out of the collar 31, and the flagpole 2 and the support rod 6 are disassembled. Then the sleeve is unscrewed from the flagpole 2, and then the rotating shaft 43 is rotated by the sleeve. The rotating rotating shaft 43 rolls up the flag 1 on the outer peripheral side of the rotating shaft 43, so that the flag 1 is pulled into the storage groove 41 for storage. As the flag 1 is gradually stored in the storage groove 41, the flag 1 is pulled into the storage groove 41. The soft strip 45 is gradually pulled into the through hole 42, and then the operator pulls the piston plate 52 to move back and forth in the circular groove 51 through the sleeve and the round rod 442, so that the gas in the storage groove 41 is gradually extracted, so that a negative pressure cavity is gradually formed in the storage groove 41, and the negative pressure cavity in the storage groove 41 exerts a pulling force on the soft strip 45 in the direction of the storage groove 41, so that the soft strip 45 is closely fitted with the inner wall of the through hole 42, thereby enhancing the blocking strength of the soft strip 45 on the through hole 42;

[0035] When the piston plate 52 moves toward the opening of the circular groove 51, the gas in the circular groove 51 can be pushed out from the gap between the round rod 442 and the circular groove 51, and at the same time, the space between the piston plate 52 and the inner bottom wall of the circular groove 51 is gradually expanded, so that a negative pressure cavity is formed between the piston plate 52 and the first one-way valve 53, and a sufficient pressure difference is generated at both ends of the first one-way valve 53, so that part of the gas in the storage tank 41 gradually flows into the circular groove 51. When the piston plate 52 moves away from the opening of the circular groove 51, the gas in the circular groove 51 is pushed out from the gap between the round rod 442 and the circular groove 51. Due to the obstruction of the first one-way valve 53, the gas in the circular groove 51 will not flow back into the storage tank 41, and the movement of the piston plate 52 makes the space between the piston plate 52 and the first one-way valve 53 gradually shrink, and the gas between the piston plate 52 and the first one-way valve 53 is pressed into the second one-way valve 53, and the second one-way valve 53 passes through the piston plate 52. According to the above repetition, most of the gas in the storage tank 41 can be gradually extracted, and the negative pressure strength in the storage tank 41 can be judged according to the resistance when the piston plate 52 is pulled;

[0036] After the gas in the storage tank 41 is discharged, the operator screws the sleeve onto the support rod 6 again. At this time, the flag 1 is stored in a relatively closed and vacuum-like environment, and the parade flags are split into two rod-shaped components, thereby reducing the volume of the parade flags when stacked.
