[0033] Reference Figures 1 to 4The utility model provides a double circulation downward hand pull flag raising structure for raising and lowering a flag 100. The double circulation downward hand pull flag raising structure comprises a flagpole 1, a pulley assembly, a rope loop 5 and a balancer 7. The pulley assembly comprises an upper pulley set 2, a middle pulley set 3 and a lower pulley set 4 arranged on the flagpole 1 and having their axes perpendicular to the axis of the flagpole 1. The rope loop 5 is wound around the upper pulley set 2, the middle pulley set 3 and the lower pulley set 4 and can move around the upper pulley set 2, the middle pulley set 3 and the lower pulley set 4. The upper pulley set 2 and the lower pulley set 4 divide the rope loop 5 into a first section 51 and a second section 52. The balancer 7 is arranged on the first section 51, and the flag 100 is arranged on the second section 52. The balancer 7 is used to balance the weight of the flag 100. At this time, the first section 51 and the second section 52 of the rope loop 5 can be operated to control the raising and lowering of the flag 100, bidirectional operation is realized, and high convenience is achieved.

[0034] The rope loop 5 in the embodiment can be a steel wire rope with a certain hardness, which can not only transmit a pulling force but also transmit a pushing force. For example, when the flag 100 needs to be raised, a worker is placed on one side of the flagpole 1 close to the first section 51 of the rope loop 5, the first section 51 of the rope loop 5 is pulled downward, the flag 100 on the second section 52 is raised until the upper limit position, and when the flag 100 needs to be lowered, the worker is placed on one side of the flagpole 1 close to the first section 51 of the rope loop 5, the first section 51 of the rope loop 5 is pushed upward, a pushing force is transmitted upward, the flag 100 on the second section 52 is lowered until the lower limit position. Alternatively, when the flag 100 needs to be raised, a worker is placed on one side of the flagpole 1 close to the second section 52 of the rope loop 5, the second section 52 of the rope loop 5 is pushed upward, the second section 52 transmits a pushing force upward, the balancer 7 of the first section 51 receives a downward pushing force, and the balancer 7 on the first section 51 can provide a downward force due to its own gravity. At this time, the pushing force of the worker and the gravity of the balancer 7 jointly act on the flag 100 to raise the flag 100 until the upper limit position, and when the flag 100 needs to be lowered, the worker is placed on one side of the flagpole 1 close to the second section 52 of the rope loop 5, the second section 52 of the rope loop 5 is pulled downward, and the flag 100 is lowered until the lower limit position.

[0035] It can be understood that before the flag 100 is raised and when the worker is placed on one side of the flagpole 1 close to the first section 51 of the rope ring 5, the first section 51 of the rope ring 5 is pulled down, so that the flag 100 on the second section 52 is raised, at this time the balancer 7 on the first section 51 can play the role of saving labor, the worker only needs small force to operate the raising process of the flag 100, reducing the operation difficulty; before the flag 100 is lowered, the balancer 7 can be disassembled from the first section 51 of the rope ring 5, facilitating the lowering of the flag 100 on the second section 52. Similarly, before the flag 100 is raised and the worker is placed on one side of the flagpole 1 close to the second section 52 of the rope ring 5, the flag 100 is raised by pushing the second section 52 of the rope ring 5 and the action of the balancer 7; before the flag 100 is lowered, the balancer 7 can be disassembled from the first section 51 of the rope ring 5, facilitating the lowering of the flag 100 on the second section 52. That is, the balancer 7 is only installed and used when the flag 100 needs to be raised, and can be disassembled when the flag 100 needs to be lowered, avoiding the worker's labor.

[0036] With reference to Figure 3 The middle pulley block 3 includes a first pulley 31 and a second pulley 32, the second pulley 32 is arranged on one side of the first pulley 31 close to the second section 52, the rope ring 5 is Z-shaped and sequentially passes through the first pulley 31 and the second pulley 32, so that the first section 51 and the second section 52 are horizontal in the axis direction of the flagpole 1, the distance between the first section 51 and the second section 52 below the middle pulley block 3 is greater than the distance between the first section 51 and the second section 52 above the middle pulley block 3, this setting can reserve more operation space for the worker in the horizontal direction, at the same time prevent the first section 51 and the second section 52 of the rope ring 5 from being entangled, and the first section 51 and the second section 52 are horizontal in the axis direction of the flagpole 1, which can avoid the flag 100 from tilting or rotating during the lifting process, thereby ensuring that the flag 100 can be lifted smoothly and smoothly.

[0037] Further, the upper edge of the first pulley 31 is not lower than the lower edge of the second pulley 32, this setting makes the contact area between the rope ring 5 and the first pulley 31 and the second pulley 32 increase when the rope ring 5 is Z-shaped and sequentially passes through the first pulley 31 and the second pulley 32, reduces the contact pressure, prolongs the service life of the rope ring 5, and at the same time improves the movement stability of the rope ring 5.

[0038] Specifically, the middle pulley set 3 is arranged close to the lower pulley set 4, and the distance between the middle pulley set 3 and the lower pulley set 4 is not less than the first preset distance and not more than the second preset distance, and the balancer 7 is arranged above the middle pulley set 3. When the staff is arranged at one side of the flagpole 1 close to the first section 51 of the rope ring 5, the rope ring 5 is operated between the middle pulley set 3 and the lower pulley set 4 to operate the flag 100 to rise and fall, the distance between the middle pulley set 3 and the lower pulley set 4 is not less than the first preset distance, which can reserve sufficient operation space for the staff on the first section 51, and the distance between the middle pulley set 3 and the lower pulley set 4 is not more than the second preset distance, so that the upper pulley set 2 and the middle pulley set 3 can have sufficient distance, and sufficient space is reserved for the movement of the balancer 7 relative to the flagpole 1.

[0039] Referring to Figure 2 In the embodiment, the upper pulley set 2 includes three third pulleys 21 arranged in a regular triangle, and the diameters of each third pulley 21 are the same, and the rope ring 5 is wound from the side away from each other of the three third pulleys 21 to form a triangular wrapping path. Alternatively, the upper pulley set 2 includes small pulleys and large pulleys arranged in an up-down arrangement, and the rope ring 5 is wound from the two sides of the small pulleys and the large pulleys to form a triangular wrapping path. The triangular wrapping path forms a triangular supporting surface between the rope ring 5 and the upper pulley set 2, which has three supporting ends, so as to realize stress distribution on the rope ring 5 and avoid excessive stress concentration on the rope ring 5 to cause wear or even breakage.

[0040] Referring to Figure 4 The lower pulley set 4 includes two fourth pulleys 41 arranged in a horizontal direction and spaced apart, and the rope ring 5 is wound from the side away from each other of the two fourth pulleys 41 to form a rectangular wrapping path, which is used to adapt to the greater distance between the first section 51 and the second section 52 after the middle pulley set 3 is arranged. The stability of the movement of the rope ring 5 on the fourth pulley 41 is improved. Preferably, the axes of the fourth pulleys 41 are in the same horizontal plane.

[0041] In order to adjust the tension of the rope ring 5 during work and ensure the stable operation of the flag 100 during lifting, the double-circulation downward hand-pulling flag raising structure further includes a tensioner 6 arranged on the rope ring 5, which can adjust the tension of the rope ring 5 in real time. Specifically, during the lifting of the flag 100, the rope ring 5 may be relaxed due to the material ductility, which affects the smooth lifting of the flag 100. The tensioner 6 can apply continuous pressure to the rope ring 5 through a spring or a hydraulic structure to ensure that the rope ring 5 is always in a tight state. Alternatively, during the lifting of the flag 100, the rope ring 5 may be too instantaneously tight due to strong wind and rapid lifting, and the tensioner 6 can absorb the instantaneous impact energy through the elastic deformation of the spring or the hydraulic structure to reduce the risk of breakage of the rope ring 5.

[0042] The double circulation downward hand-pulled flag raising structure further comprises a flag hanging piece 8 fixedly arranged on the second section 52 and used for mounting a flag 100.

[0043] Further, in order to improve the appearance of the whole double circulation downward hand-pulled flag raising structure, the expander 6 is arranged inside the flag hanging piece 8, specifically inside the main piece, so that the expander 6 is not exposed and the safety of the expander 6 is ensured.

[0044] The flagpole 1 device further comprises a ball head 11 arranged at the top of the flagpole 1, which improves the appearance of the whole double circulation downward hand-pulled flag raising structure. The double circulation downward hand-pulled flag raising structure further comprises a locking piece used for locking the rope ring 5, so as to ensure the fixation of the flag 100 at any position and avoid the unnecessary rising and falling of the flag 100.

[0045] With reference to Figure 1 and Figure 5 , the double circulation downward hand-pulled flag raising structure further comprises a mounting flange 9, the bottom of the flagpole 1 is provided with a mounting seat 12, the mounting flange 9 comprises a bottom disc 91 and a sleeve 92 extending axially from the flagpole 1, and the mounting seat 12 is arranged in the sleeve 92. The mounting of the flagpole 1 in the vertical direction is completed through the cooperation of the mounting seat 12 and the mounting flange 9.

[0046] Further, the mounting flange 9 is further provided with a reinforcing rib 93 arranged between the bottom disc 91 and the sleeve 92, which strengthens the supporting strength of the mounting flange 9 and ensures the stability of the installation of the flagpole 1.

[0047] The embodiment further provides an exhibition flag platform, which comprises a base platform 10 and the double circulation downward hand-pulled flag raising structure. The flagpole 1 of the double circulation downward hand-pulled flag raising structure is arranged on the base platform 10. Further, the mounting flange 9 of the double circulation downward hand-pulled flag raising structure can be connected with the base platform 10, so as to install the flagpole 1 on the base platform 10. The bottom disc 91 of the mounting flange 9 is provided with a threaded hole, and a screw can be used to pass through the threaded hole to fix the mounting flange 9 on the base platform 10, so as to fix and install the flagpole 1 on the base platform 10.
