[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the bracket device is not in use, the four second suction cups are fixed inside the grooves on the side of the mounting block, so that the bracket device can be conveniently driven for transfer and installation, thereby improving the convenience of using the entire bracket device. When a billboard needs to be installed, the position where the billboard needs to be installed is first measured. According to the shape of different billboards, the second suction cup is pulled to fix the second suction cup at the position where it needs to be installed. The second suction cup fixed at multiple points can achieve a better stabilizing effect and reduce the occurrence of swinging.

[0020] There are two installation methods: the first is to fix the installation components. During installation, the installation part of the billboard is fixed on multiple installation components to complete the fixation of the billboard position. It is suitable for the installation of low-altitude billboards. The second is to separate the installation components. First, fix the edge of the billboard on multiple installation components, and then pull the multiple installation components by the winch to the position of the second suction cup to complete the fixation. It is suitable for the installation of high-altitude billboards.

[0021] When the wind is strong, the wind will enter from the bottom of the wind hood and move to the top of the wind hood. During the movement, the wind will cause impact and compression on the wind hood, thereby driving the wind hood to move upward. During the upward movement of the wind hood, the sealing plug will move upward. The upwardly moving sealing plug will draw the gas inside the suction cup upward, thereby increasing the negative pressure inside the suction cup, increasing the pressure between the suction cup and the glass curtain wall, and thus strengthening the connection between the fixing frame and the glass curtain wall.

[0022] When the elastic block is not squeezed, the bottom surface of the sealing ring capsule is located below the bottom surface of the second suction cup. During the installation of the second suction cup, the elastic block will be squeezed, so that the sealing ring capsule and the glass curtain wall are in sealed contact, which prevents the second suction cup from being infiltrated by rainwater in rainy weather, thereby ensuring that the second suction cup will not loosen after the adsorption and fixation is completed, and ensuring the fixation of the billboard position;

[0023] In windy and rainy weather, in order to ensure the sealing effect, the wind entering the wind cover will squeeze the extrusion bag, squeezing the liquid inside the extrusion bag into the sealing ring bag, thereby strengthening the sealing contact between the sealing ring bag and the glass curtain wall in windy weather and preventing the entry of water vapor;

[0024] In order to facilitate the folding of the bracket device when not in use, the fixing plate on the second suction cup is inserted into the fixing groove, so that multiple second suction cups are fixed to the side of the mounting block, so that the entire bracket device becomes a gathered whole, which facilitates the transfer of the bracket device. At the same time, the setting of the fixing plate and the fixing bolt facilitates the rapid fixing and installation of the second suction cup, thereby improving the convenience of the bracket device.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0038] Reference Figure 1-Figure 10 A bracket device for outdoor curtain wall billboards, comprising: a mounting block 1 and a first suction cup 2 fixed to the bottom of the mounting block 1, the mounting block 1 having four grooves annularly arranged on the side thereof, four second suction cups 3 respectively arranged inside the four grooves, a mounting assembly 4 being arranged above each of the four second suction cups 3, and the four mounting assemblies 4 being used to fix the billboard from four corners;

[0039] A cable assembly 5 is arranged between the mounting assembly 4 and the mounting block 1, and the cable assembly 5 includes a winch 51 and a rope 52. A plurality of mounting grooves are provided on the mounting block 1, and the winch 51 is fixedly installed inside the mounting groove. An arc-shaped channel is provided on the side of the mounting groove, and one end of the arc-shaped channel is provided in the middle of the groove. One end of the rope 52 is fixedly installed on the winch 51, and the other end passes through the arc-shaped channel and is fixedly connected to the mounting assembly 4.

[0040] In the embodiment of the above technical solution, when the bracket device is not used, by fixing the four second suction cups 3 inside the groove on the side of the mounting block 1, it is convenient to drive the bracket device to transfer and install, thereby improving the convenience of the entire bracket device. When it is necessary to install a billboard, first measure the position where the billboard needs to be installed. According to the shape of different billboards, by pulling the second suction cup 3, the second suction cup 3 is fixed at the position where it needs to be installed. The multi-point fixed second suction cup 3 can play a better stabilizing effect and reduce the occurrence of swinging. There are two installation methods during installation. The first method is to fix the mounting component 4. During installation, the mounting part of the billboard is fixed on multiple mounting components 4, thereby completing the fixation of the billboard position, which is suitable for the installation of low-altitude billboards; the second method is to separate the mounting component 4, first fix the edge of the billboard on multiple mounting components 4, and then pull the multiple mounting components 4 through the winch 51 to pull the mounting component 4 to the position of the second suction cup 3, thereby completing the fixation, which is suitable for the installation of high-altitude billboards. The present invention can reduce the swing of the billboard and can fix and install billboards of various shapes.

[0041] The preferred technical solution in this embodiment is:

[0042] Reference Figure 4-5 The mounting assembly 4 includes a limiting frame 41, a fixing ring 42, a threaded seat 43 and a fixing frame 44. The limiting frame 41 is fixedly connected to the upper end of the second suction cup 3, the fixing ring 42 is rotatably mounted on the upper side of the limiting frame 41, the threaded seat 43 is threadedly connected to the upper side of the fixing ring 42, and the fixing frame 44 is fixedly connected to the upper end of the threaded seat 43 for fixing the billboard;

[0043] The limiting frame 41 is provided with a limiting groove 9 inside. The limiting groove 9 has an inlet at one side close to the mounting block 1 and an outlet at the upper end. One end of the rope 52 passes through the limiting groove 9 and is rotatably connected to the bottom end of the threaded seat 43 .

[0044] The shape of the fixing frame 44 is selected according to the shape of the billboard to be installed, and is threadedly connected to the fixing ring 42 through the threaded seat 43, thereby fixing the position of the limiting frame 41, facilitating the rapid installation and removal of the fixing frame 44, and facilitating the replacement of fixing frames 44 of different shapes.

[0045] The limiting groove 9 is used to limit the position of the rope 52, and can ensure the normal movement of the rope 52 during the process of releasing and retracting the rope 52.

[0046] Since the bracket device has multiple ways to install the billboard, after the second suction cup 3 is fixed, the second suction cup 3 and the fixing frame 44 can be separated, the length of the rope 52 can be extended, the fixing frame 44 can be moved down, and multiple fixing frames 44 can be installed at the four corners of the billboard. Then, the fixing frame 44 can be quickly moved up by pulling the rope 52 to fix the position of the fixing frame 44 and the limit frame 41. This method is safer during high-altitude installation and avoids the billboard from falling during the installation process.

[0047] Reference Figure 5-6 The second suction cup 3 includes a control tube 31, a suction cup sheet 32 ​​and a sealing plug 33. An air valve is provided on the side of the control tube 31. The suction cup sheet 32 ​​is fixedly connected to the bottom end of the control tube 31. A sliding cavity is provided inside the control tube 31. The sealing plug 33 is sealingly and slidingly provided inside the sliding cavity.

[0048] When using the second suction cup 3, the suction cup piece 32 is first limited on the surface of the glass curtain wall. At this time, the air inside the suction cup piece 32 is extracted through the air valve through the external suction device. The sealing plug 33 has a one-way valve inside to ensure the normal extraction of the gas inside the suction cup piece 32, so that negative pressure is formed between the suction cup piece 32 and the glass curtain wall to fix the position of the second suction cup 3.

[0049] Reference Figure 7-9 The sliding cavity has two sliding grooves 10 symmetrically formed on its side, the length of the sealing plug 33 is greater than the length of the two sliding grooves 10, and the sealing plug 33 is provided with an air guide component 6, which is used to drive the sealing plug 33 to slide upward inside the sliding cavity;

[0050] The air guide assembly 6 includes two side frames 61 and an air cover 62. The two side frames 61 are symmetrically fixedly connected to the two sides of the sealing plug 33 and are slidably arranged inside the sliding groove 10. The air cover 62 is a truncated cone-shaped cover, and the inner side of the upper end is fixedly connected to the ends of the two side frames 61. The distance between the lower side of the air cover 62 and the suction cup sheet 32 ​​is greater than the distance between the upper side of the air cover 62 and the suction cup sheet 32.

[0051] Since the billboard is set outdoors, after installation, if there is a strong wind outdoors, the billboard will swing under the action of the wind. After multiple swings, the position of the second suction cup 3 may shift, causing the installation position of the billboard to loosen, which may easily cause the billboard to shift and fall, posing a certain safety hazard.

[0052] When the wind is strong, the wind will enter from the bottom of the wind hood 62 and move toward the top of the wind hood 62. During the movement, the wind will cause impact and compression on the wind hood 62, thereby driving the wind hood 62 to move upward. During the upward movement of the wind hood 62, it will drive the sealing plug 33 to move upward. The upwardly moved sealing plug 33 will draw the gas inside the suction cup sheet 32 ​​upward, thereby causing the negative pressure inside the suction cup sheet 32 ​​to increase, thereby increasing the pressure between the suction cup sheet 32 ​​and the glass curtain wall, thereby strengthening the connection between the fixing frame 44 and the glass curtain wall.

[0053] Reference Figure 7-9 A waterproof component 7 is provided inside the wind shield 62, and the waterproof component 7 is used to seal and waterproof the bottom side of the second suction cup 3;

[0054] The waterproof assembly 7 includes two elastic blocks 71, a mounting ring 72, a sealing ring capsule 73 and an extrusion capsule 74. The two elastic blocks 71 are symmetrically fixedly connected to the inner side of the wind shield 62. The mounting ring 72 is fixedly connected to the bottom ends of the two elastic blocks 71. The sealing ring capsule 73 is fixedly connected to the bottom of the mounting ring 72. The extrusion capsule is arranged in the middle of the mounting ring 72. A connecting channel connecting the extrusion capsule 74 and the sealing ring capsule 73 is opened inside the mounting ring 72.

[0055] An air guide ring groove 11 is formed in the middle of the mounting ring 72 . The air guide ring groove 11 is concave inwardly in an arc shape for guiding air upward. The extrusion bag 74 is installed at the bottom of the air guide ring groove 11 .

[0056] Since the billboard is set outdoors, in windy and rainy weather, rainwater will penetrate to the edge of the suction cup sheet 32. When there is a gap between the suction cup sheet 32 ​​and the glass curtain wall, rainwater will easily penetrate and affect the fixation of the suction cup sheet 32. Therefore, the side of the suction cup sheet 32 ​​needs to be waterproofed.

[0057] When the elastic block 71 is not squeezed, the bottom surface of the sealing ring capsule 73 is located below the bottom surface of the second suction cup 3. During the installation of the second suction cup 3, the elastic block 71 will be squeezed, so that the sealing ring capsule 73 and the glass curtain wall are in sealed contact, avoiding the infiltration of rainwater into the second suction cup 3 in rainy weather, thereby ensuring that the second suction cup 3 will not loosen after completion of adsorption and fixation, thereby ensuring the fixation of the billboard position.

[0058] In windy and rainy weather, in order to ensure the sealing effect, the wind entering the wind cover 62 will squeeze the extrusion bag 74, squeezing the liquid inside the extrusion bag 74 into the sealing ring bag 73, thereby strengthening the sealing contact between the sealing ring bag 73 and the glass curtain wall in windy weather and preventing the entry of water vapor.

[0059] Reference Fig.10A fixing component 8 is arranged between the second suction cup 3 and the mounting block 1, and the fixing component 8 includes a fixing groove 81, a fixing bolt 82 and a fixing plate 83. The fixing groove 81 is opened in the middle of the bottom side of the groove, and the fixing plate 83 is fixedly connected to the side of the second suction cup 3. The fixing bolt 82 is arranged at the bottom of the fixing groove 81 to limit the position of the fixing plate 83 inside the fixing groove 81.

[0060] In order to facilitate the folding of the bracket device when not in use, the fixing plate 83 on the second suction cup 3 is inserted into the fixing groove 81, so that multiple second suction cups 3 are fixed to the side of the mounting block 1, so that the entire bracket device becomes a gathered whole, which facilitates the transfer of the bracket device. At the same time, the setting of the fixing plate 83 and the fixing bolt 82 facilitates the rapid fixing and installation of the second suction cup 3, thereby improving the convenience of the bracket device.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
