As a result, the gas in the air injection cylinder is compressed and introduced into the telescopic airbag through a conduit. The telescopic end of the telescopic airbag can abut between the first mounting shaft and the second mounting shaft, thereby buffering the bottom of the protective net. In this way, the impact hazard to the top of the protective net is reduced, and the protection of the protective net is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1: This embodiment introduces a mobile building decoration protective net installation component, as Figure 3 - Figure 8 shown. A mobile building decoration protective net installation component includes a fixed plate 1 and a protective net 34. Mounting rods 11 are respectively and fixedly installed on both sides of the front surface of the fixed plate 1. A lifting mechanism 2 is installed on the top of the fixed plate 1. The lifting mechanism 2 is used for hoisting and installing the protective net 34. A mounting component 3 is installed on the front surface of the fixed plate 1. The mounting component 3 is used for installing and fixing the protective net 34. The mounting component 3 includes an assembling plate 31 slidably installed on the mounting rod 11. A first mounting shaft 32 and a second mounting shaft 33 are respectively rotatably installed between two groups of assembling plates 31 through rotating shafts. The protective net 34 is respectively wound around the first mounting shaft 32 and the second mounting shaft 33. A rack 38 is fixedly installed at one end of the top of the assembling plate 31 close to the fixed plate 1. The protective net 34 is arranged on the front surface of the fixed plate 1. In this embodiment, the servo motor 21 in the lifting mechanism 2 drives the rotating rod 22 and the external wire reel 23 to rotate, so that the lifting rope 25 wound around the wire reel 23 hoists the assembly plate 31 through the lifting ring 26. The protective net 34 is wound around the first mounting shaft 32 and the second mounting shaft 33. By fixing the fixing plate 1 at the installation position of the building protective net 34, the stop blocks 35 on the outer side of the assembly plate 31 respectively engage and lock the second locking gears 36 at the ends of the first mounting shaft 32 and the second mounting shaft 33. Thus, the first mounting shaft 32 and the second mounting shaft 33 can be locked and positioned between the two assembly plates 31 by the fastening bolts 37 outside the stop blocks 35. In this way, the protective net 34 wound around the outer sides of the first mounting shaft 32 and the second mounting shaft 33 can be positioned outside the building after being obliquely unfolded, playing a protective role against falling objects outside the building; In this embodiment, the wire reel 23 on the rotating rod 22 hoists and positions the assembly plate 31 at a specified position outside the building through the lifting rope 25. The two ball screws 42 are driven by the synchronization mechanism 6, so that the rack 38 at the bottom of the assembly plate 31 can engage with the corresponding stable gear 45 below. The stable gear 45 drives the second bevel gear 54 through the first bevel gear 46 at the end of the through rod 44. The spline shaft 53 at the top of the second bevel gear 54 synchronously drives the spline sleeve 52 to drive the threaded sleeve 55. The carriage 56 and the top arc-shaped tooth block 58 externally threaded to the threaded sleeve 55 bite and position the first locking gear 222 on the same side, realizing the locking and positioning of the rotating rod 22 around which the lifting rope 25 is wound. In this way, after the protective net 34 between the assembly plates 31 is hoisted to the specified position on the front of the fixing plate 1, it can be locked by the arc-shaped tooth block 58, thus improving the stability of the protective net 34 after being slidably installed on the mounting rods 11 on both sides of the front of the fixing plate 1; Among them, the lifting mechanism 2 includes a servo motor 21 fixedly installed on the top of the fixed plate 1. The output end of the servo motor 21 is fixedly connected to a rotating rod 22. The middle parts of both ends of the rotating rod 22 are respectively fixedly sleeved with wire winding rollers 23. On the top of the fixed plate 1, wire guiding wheels 24 are respectively fixedly installed near the edge on one side of the protective net 34. A lifting rope 25 is wound around the outside of the wire winding roller 23. The bottom end of the lifting rope 25 is fixedly connected to a hanging ring 26. The lifting rope 25 extends to the wire guiding wheel 24 on the same side, and the bottom end of the lifting rope 25 extends to the assembly plate 31 on the same side. At both ends of the top of the fixed plate 1, mounting seats 221 are respectively fixedly installed. The rotating rod 22 is rotatably installed on the mounting seat 221 on the same side. A first locking gear 222 is fixedly sleeved at one end of the rotating rod 22 away from the mounting seat 221. In this embodiment, the wire winding roller 23 on the rotating rod 22 hoists and positions the assembly plate 31 at a specified position on the outer side of the building through the lifting rope 25. By adjusting the two sets of ball screws 42, the rack 38 at the bottom of the assembly plate 31 can be engaged with the corresponding stable gear 45 below. The stable gear 45 can engage and position the arc-shaped tooth block 58 on the carriage 56 with the first locking gear 222 on the same side under the cooperation of the first bevel gear 46, the second bevel gear 54, the spline shaft 53, the spline sleeve 52 and the threaded sleeve 55 on the outside of the through rod 44, so as to lock and position the rotating rod 22 that winds the lifting rope 25 on the protective net 34. In this way, after the protective net 34 between the assembly plates 31 is hoisted to the specified position on the front of the fixed plate 1, it can be locked by the arc-shaped tooth block 58.

[0021] Among them, the installation component 3 further includes a second locking gear 36 fixedly sleeved on the rotating shafts at both ends of the first installation shaft 32 and the second installation shaft 33. A stop block 35 is externally engaged with each group of second locking gears 36. A fastening bolt 37 is threadedly installed between the ear plates on the outer circumference of the stop block 35 and the assembly plate 31 on the same side. At the middle part on one side of the two assembly plates 31 close to the protective net 34, hanging rings 26 are also fixedly installed. The hanging rings 26 on the assembly plate 31 and the hanging rings 26 connected to the bottom ends of the lifting ropes 25 on the same side are fixedly staggered with each other. In this embodiment, the arc-shaped tooth block 58 and the first locking gear 222 at the end of the rotating rod 22 on the same side are located on the same straight line. The servo motor 21 in the lifting mechanism 2 drives the rotating rod 22 and the external wire winding roller 23 to rotate, so that the lifting rope 25 wound around the wire winding roller 23 hoists the assembly plate 31 through the hanging ring 26.

[0022] Among them, first mounting blocks 51 are fixedly installed on the sides of the two groups of first mounting plates 41 away from the protective net 34. A spline sleeve 52 is rotatably installed on the top of the first mounting block 51. A spline shaft 53 is slidably connected inside the spline sleeve 52. The bottom end of the spline shaft 53 is fixedly connected with a second bevel gear 54. The outer edge of the second bevel gear 54 meshes with the outer edge of the first bevel gear 46 on the same side. A threaded sleeve 55 is fixedly sleeved on the spline sleeve 52 located on the top of the first mounting block 51. The transmission assembly 5 further includes second mounting plates 57 fixedly installed on the top of both sides of the fixing plate 1. A second guiding groove 571 is penetrated and opened in the middle of the outer side of the second mounting plate 57. Chute grooves 12 are respectively opened at the top of both sides of the fixing plate 1 close to the second mounting plate 57. A sliding frame 56 is slidably connected in the chute groove 12 on the same side and the second guiding groove 571 on the same side. The sliding frame 56 is threadedly connected with the threaded sleeve 55 on the same side. An arc-shaped tooth block 58 is fixedly installed on the top of the sliding frame 56. A synchronization mechanism 6 is arranged on the top of the front surface of the fixing plate 1. The synchronization mechanism 6 is fixedly installed on the second mounting block 62 on the top of the front surface of the fixing plate 1. The synchronization mechanism 6 further includes three synchronous belt pulleys 63. Two of the synchronous belt pulleys 63 are fixedly sleeved on the tops of the corresponding ball screw rods 42. The other synchronous belt pulley 63 is rotatably installed on the top of the second mounting block 62. A synchronous belt 61 meshes with the outside of the three synchronous belt pulleys 63. A flange plate 64 is fixedly installed on the synchronous belt pulley 63 located on the top of the second mounting block 62. In this embodiment, by driving one of the synchronous belt pulleys 63 to rotate through the flange plate 64, the synchronous belt pulley 63 drives the synchronous belt pulleys 63 at the tops of the two ball screw rods 42 through the synchronous belt 61, so that the two ball screw rods 42 can drive the guide blocks 43 in the first guiding groove 411 to adjust their positions up and down. The first bevel gear 46 on the outside of the guide block 43 and the second bevel gear 54 at the bottom end of the spline shaft 53 can synchronously slide and adjust their positions in the spline sleeve 52. In this way, after the protective net 34 between the assembly plates 31 is hoisted onto the mounting rods 11 on the front surface of the fixing plate 1 by the lifting ropes 25 and slides to the designated position of the building, the adjusting assembly 4 and the transmission assembly 5 can make synchronous adjustments. When the protective net 34 is installed at different height positions, it can be synchronously adjusted by the structural members and then locked and positioned.

[0023] Among them, the outer edge of the rack 38 meshes with the outer edge of the stabilizing gear 45 on the same side. The arc-shaped tooth block 58 meshes with the first locking gear 222 on the same side. In this embodiment, after the protective net 34 between the assembly plates 31 is hoisted to the designated position on the front surface of the fixing plate 1, it can be locked by the arc-shaped tooth block 58, which improves the stability of the protective net 34 after being slidably installed on the mounting rods 11 on both sides of the front surface of the fixing plate 1.

[0024] Embodiment 2: Based on Embodiment 1, this embodiment introduces a mobile building decoration protective net installation component, such as Figure 6 - Figure 11As shown, adjustment components 4 and transmission components 5 are respectively arranged on both sides of the front surface of the fixed plate 1. The adjustment component 4 and the transmission component 5 are respectively used for strengthening and stabilizing the protective net 34. In this embodiment, one set of synchronous belt pulleys 63 is driven to rotate by the flange 64. The synchronous belt pulleys 63 drive the synchronous belt pulleys 63 at the tops of the two ball screws 42 through the synchronous belt 61, so that the two ball screws 42 can drive the guide blocks 43 in the first guide groove 411 to adjust their positions up and down. The first bevel gear 46 on the outside of the guide block 43 and the second bevel gear 54 at the bottom of the spline shaft 53 can slide synchronously in the spline sleeve 52 to adjust their positions. In this way, when the protective net 34 between the assembly plates 31 is hoisted onto the mounting rod 11 by the lifting rope 25 and slides to the designated protective position of the building, the adjustment component 4 and the transmission component 5 can make synchronous adjustments. When the protective net 34 is installed at different height positions, it can be synchronously adjusted by the structural members and then locked and positioned. Therefore, after the protective net 34 is adjusted to different height positions, it can still be stably positioned on the building structure, improving the stability of the adjustable installation position of the protective net 34. Among them, the adjustment component 4 includes first mounting plates 41 fixedly installed on both sides of the front surface of the fixed plate 1. First guide grooves 411 are respectively formed through the left sides of the two first mounting plates 41. The adjustment component 4 further includes ball screws 42 rotatably installed on the inner walls of the first guide grooves 411. A guide block 43 is threadedly connected to the outside of the ball screw 42, and the guide block 43 slides on the inner wall of the first guide groove 411. A through rod 44 is rotatably installed between the two guide blocks 43. A stabilizing gear 45 is fixedly sleeved on the outside of the through rod 44 near the two racks 38. A first bevel gear 46 is fixedly installed on the outside of the guide block 43. The winding roller 23 on the rotating rod 22. In this embodiment, the assembly plate 31 is hoisted and positioned at a designated position outside the building through the lifting rope 25. The rack 38 at the bottom of the assembly plate 31 can be engaged with the corresponding stabilizing gear 45 below. The stabilizing gear 45 drives the second bevel gear 54 through the first bevel gear 46 at the end of the through rod 44. The spline shaft 53 at the top of the second bevel gear 54 and the spline sleeve 52 synchronously drive the threaded sleeve 55. The carriage 56 threadedly connected to the outside of the threaded sleeve 55 and the top arc-shaped tooth block 58 engage and position the first locking gear 222 on the same side.

[0025] Embodiment 3: Based on Embodiment 1, this embodiment introduces a mobile building decoration protective net installation component, such as Figure 1 、 Figure 6 and Figure 11As shown, in this embodiment, injection cylinders 47 are installed on both sides of the bottom of the fixing plate 1 through brackets. The piston end at the top of the injection cylinder 47 abuts against the same-side rack 38. When the assembly plate 31 and the protective net 34 are subjected to a huge impact, causing relative displacement between the rack 38 and the stable gear 45 and between the arc-shaped tooth block 58 and the first locking gear 222, the rack 38 moves downward by a certain distance, squeezing the piston end at the top of the injection cylinder 47 to form a buffer. As a result, the gas in the injection cylinder 47 is compressed and introduced into the telescopic airbag 49 through the air duct 48. The telescopic end of the telescopic airbag 49 can abut between the first mounting shaft 32 and the second mounting shaft 33, thereby buffering the bottom of the protective net 34. In this way, the impact hazard on the top of the protective net 34 is reduced, and the protection of the protective net 34 is realized.

[0026] Among them, a telescopic airbag 49 is fixedly installed at the bottom of the protective net 34 between the first mounting shaft 32 and the second mounting shaft 33. The injection cylinder 47 is connected to the telescopic airbag 49 through the air duct 48. The piston end of the injection cylinder 47 is fixedly connected to the bottom of the same-side rack 38. In this embodiment, when there is displacement between the rack 38 and the stable gear 45 and between the arc-shaped tooth block 58 and the first locking gear 222, the rack 38 moves downward by a certain distance, squeezing the piston end at the top of the injection cylinder 47 to form a buffer. The telescopic airbag 49 can abut between the first mounting shaft 32 and the second mounting shaft 33 through inflation and expansion, thereby buffering the bottom of the protective net 34.

[0027] Among them, an injection cylinder 47 is provided on the front of the fixing plate 1 and at the bottom of the protective net 34. An air duct 48 is fixedly installed at the air outlet of the injection cylinder 47. In this embodiment, the base of the injection cylinder 47 slides in the same-side first guide groove 411, and one side of the base is also connected to the ball screw 42 in the first guide groove 411 through a threaded fit. When the ball screw 42 drives the stable structure of the bottom of the protective net 34 in the synchronous mechanism 6, the injection cylinder 47 can adjust the height synchronously with the protective net 34.

[0028] Working principle: When in use, first, after the protective net 34 on the first mounting shaft 32 and the second mounting shaft 33 between the two sets of assembly plates 31 is unfolded and tightened, it is engaged and locked by the second locking gear 36 at the end. As a result, the first mounting shaft 32 and the second mounting shaft 33 can be locked and positioned between the two sets of assembly plates 31 through the fastening bolts 37 outside the stop block 35. In this way, the protective net 34 wound around the outside of the first mounting shaft 32 and the second mounting shaft 33 can be positioned outside the building after being obliquely unfolded, playing a protective role against falling objects outside the building; Then, the two sets of assembly plates 31 are respectively slidably installed on the two sets of mounting rods 11; Then, the wire winding roller 23 on the rotating rod 22 hoists and positions the assembly plate 31 at a specified position outside the building through the suspension rope 25. Then, by driving one group of synchronous belt pulleys 63 through the flange 64, the synchronous belt pulleys 63 drive the synchronous belt pulleys 63 at the tops of the two ball screws 42 through the synchronous belt 61, so that the two ball screws 42 can drive the guide blocks 43 in the first guide groove 411 to adjust their positions up and down. The first bevel gear 46 on the outside of the guide block 43 and the second bevel gear 54 at the bottom end of the spline shaft 53 can slide and adjust their positions synchronously in the spline sleeve 52. In this way, when the protective net 34 between the assembly plates 31 slides while being hoisted on the mounting rod 11, the adjustment assembly 4 and the transmission assembly 5 can make synchronous adjustments. When the protective net 34 is installed at different height positions, it can be synchronously adjusted by the structural members and then locked and positioned. Finally, when the protective net 34 is in use, the wire winding roller 23 on the rotating rod 22 hoists and positions the assembly plate 31 at a specified position outside the building through the suspension rope 25. The two ball screws 42 are driven by the synchronous mechanism 6, so that the rack 38 at the bottom of the assembly plate 31 can mesh with the corresponding stable gear 45 below. The stable gear 45 drives the second bevel gear 54 through the first bevel gear 46 at the end of the through rod 44. The spline shaft 53 at the top of the second bevel gear 54 and the spline sleeve 52 synchronously drive the threaded sleeve 55. The carriage 56 externally threaded to the threaded sleeve 55 and the top arc-shaped tooth block 58 bite and position the first locking gear 222 on the same side. In this way, after the protective net 34 between the assembly plates 31 is hoisted to the specified position on the front of the fixed plate 1, it can be locked by the arc-shaped tooth block 58, which improves the stability of the protective net 34 after it is slidably installed on the mounting rods 11 on both sides of the front of the fixed plate 1.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
