[0001] The invention relates to the technical field of blinds, in particular to a blind silent adjustment buffer component. Background Art

[0002] Urban noise refers to all kinds of noise generated by construction, transportation, industrial production and daily life in the city. The interference and harm of urban noise to residents are becoming increasingly serious. It has become a part of the urban environment. Urban noise interferes with residents' work, study, rest and sleep. In severe cases, it will endanger human health and cause diseases and noise-induced deafness. Therefore, the sound insulation performance of building doors and windows directly affects people's quality of life.

[0003] With their special design and materials, Venetian blinds can effectively absorb and block some noise, especially when the blinds blades are closed, the noise blocking ability will be improved. However, due to the large number of blades and complex structure of Venetian blinds during use, maintenance may be relatively difficult.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 8 The present invention provides a technical solution: a shutter silent adjustment buffer component, comprising:

[0035] Fixed frame 1;

[0036] A drive box 2 is arranged on the top of the fixing frame 1. The drive box 2 is used to adjust the blade position of the blinds and can be switched and adjusted according to different noises;

[0037] The rotating storage component 3 has transmission grooves on both sides of the fixed frame 1, and the rotating storage component 3 is movably arranged inside the transmission groove. The rotating storage component 3 can be movably operated under the control of the driving box 2;

[0038] The noise reduction and silencing components 4 are evenly arranged inside the fixing frame 1, and are clamped between the rotating storage components 3. The noise reduction and silencing components 4 can cooperate with each other to play a role of sealing and noise reduction. When it is necessary to isolate external noise, the control motor 21 inside the driving box 2 can be used to drive the rotating storage component 3 to move, thereby controlling the angular position of the noise reduction and silencing components 4, which can play a role of sealing and isolation, and can effectively isolate part of the noise. The noise reduction and silencing components 4 are easy to clean and maintain, can reduce dust accumulation that affects its noise reduction function, and are convenient for subsequent maintenance and cleaning.

[0039] like Figure 2 As shown, in order to adjust the position of the noise reduction and silencing component according to different environments, a control motor 21 is provided inside the driving box 2, and the control motor 21 is installed in the middle section of the driving box 2. A transmission rod 1 22 and a transmission rod 23 are provided at both ends of the control motor 21. The transmission rod 1 22 is tubular, and the transmission rod 1 22 is located outside the transmission rod 23, and the transmission rod 1 22 and the transmission rod 23 are concentrically arranged. A winding ring is provided on the surface of the transmission rod 1 22, and one end of the recovery belt 341 is clamped on the winding ring. As the transmission rod 1 22 rotates, the rotating storage assembly 3 can be stacked and stored, which is convenient for ventilation of the room and can be adjusted according to the usage situation.

[0040] A winding reel 24 is installed on the transmission rod 23, an annular groove is provided on the outer wall of the winding reel 24, and a compression ring is provided on the inner wall of the annular groove. The transmission belt 32 can be clamped inside the annular groove on the surface of the winding reel 24, and is used to adjust the angle of the noise reduction and silencing component 4, which can play a role in noise reduction and silencing.

[0041] like Figure 3 As shown, since the transmission belt 32 will expand during use, in order to reduce its detachment and affect the operation of the equipment, a pair of fixed bridge frames 25 are installed inside the drive box 2, and the position of the fixed bridge frame 25 corresponds to the winding disk 24. A straight groove is opened on the fixed bridge frame 25, and a buffer pressure plate 26 is installed inside the straight groove. The buffer pressure plate 26 is arc-shaped and its position corresponds to the annular groove. The buffer pressure plate 26 is used to ensure auxiliary limiting to prevent unexpected detachment during the transmission control process. The buffer pressure plate 26 can play a limiting role and can play a dust cleaning role during the transmission process. The dust attached to the surface of the transmission belt 32 during long-term use can be cleaned and adsorbed, which can make subsequent maintenance more convenient. There is no need to disassemble the transmission belt 32, and only the buffer pressure plate 26 needs to be disassembled for cleaning and maintenance, thereby reducing the maintenance cost of the blinds.

[0042] like Figure 4 and Figure 5 As shown, in order to isolate various outdoor noises, the rotating storage assembly 3 includes a sliding seat 31, a clamping ring 33 and a limiting plate 34. The sliding seat 31 is movably arranged inside the transmission groove, the clamping ring 33 is installed on one side of the sliding seat 31, a sliding groove is provided on the inner wall of the fixed frame 1, the clamping ring 33 is movably clamped inside the sliding groove, the limiting plate 34 is installed on one side of the clamping ring 33, a through groove is provided on the sliding seat 31, and a transmission belt 32 is movably clamped inside the through groove, the transmission belt 32 is elastic, one end of the transmission belt 32 is arranged inside the drive box 2, the transmission belt 32 is movably arranged inside the winding disk 24, and the sliding seat 31 is provided with a through groove. A docking shaft 35 is rotatably provided inside the movable seat 31, and the outer wall of the docking shaft 35 is against the inner wall of the transmission belt 32. The docking shaft 35 can rotate along with the transmission belt 32. The transmission belt 32 can rotate the docking shaft 35 with the help of friction during the transmission process, and can rotate the noise reduction and sound insulation components 4 between the docking shafts 35, thereby isolating the noise. The connection positions of the noise reduction and sound insulation components 4 between the docking shafts 35 can be adjusted and rotated, so that the positions of the noise reduction and sound insulation components 4 can be consistent, avoiding deviation and tilting due to external force, collision and impact, and ensuring the sealing and sound insulation functions of the blinds.

[0043] like Figure 7As shown, in order to ensure the indoor ventilation efficiency, a circular groove is opened on the limit plate 34, and the docking shaft 35 passes through the circular groove and is clamped at both ends of the noise reduction and silencing component 4. A reset plate is installed between the limit plates 34, and the reset plate is elastic. A straight hole is opened on the limit plate 34, and a recovery belt 341 is provided inside the straight hole. A connecting ball is provided at the bottom of the recovery belt 341, and the top of the recovery belt 341 is clamped on the surface of the winding ring. The control motor 21 can make the winding ring rotate, and the recovery belt 341 can be evenly wound on its surface, which can reduce the gap of the sliding seat 31, so that the rotating storage component 3 and the noise reduction and silencing component 4 are stacked together, which can facilitate indoor ventilation and can be adjusted according to specific circumstances.

[0044] like Figure 8 As shown, in order to ensure the sound insulation effect of the blinds, the noise reduction and mute component 4 includes a pair of connecting plates 41 and sound insulation blades 42. The connecting plate 41 is installed on one side of the rotating storage component 3. A pair of slots are opened on the connecting plate 41, and the slots are staggered. The sound insulation blades 42 are installed between the connecting plates 41. The sound insulation blades 42 are arc-shaped and have arc-shaped extension pieces at both ends. The two ends of the sound insulation blades 42 are made of elastic material. The two sides of the sound insulation blades 42 can be pressed together to block noise reduction. A plurality of grid pieces 43 are provided on the sound insulation blades 42. The grid pieces 43 are rectangular and the two ends pass through the inner side of the extension pieces of the sound insulation blades 42. A sound-absorbing cotton board is provided inside the grid pieces 43. After the sound insulation blades 42 are rotated, the arc-shaped extension pieces on both sides can be pressed and contacted, which can play a sealing role, can be used to isolate noise, and reduce the situation where sound is transmitted through the gap. The sound insulation cotton arranged inside the grid pieces 43 can also play a noise reduction role, which can effectively reduce the noise transmitted into the room and create a quiet rest environment.

[0045] When maintenance is needed later, the side of the sound insulation blade 42 with the mesh piece 43 can be directed toward the room, and it can be tilted at 10 to 15 degrees, so that the edge of the sound insulation blade 42 is in contact but not squeezed, and the water flow can wash away larger debris. At the same time, the mesh piece 43 swings under the action of the water flow, which can promote the edge of the sound insulation blade 42 to move and rub slightly, and can clean small particles of dust attached to its surface. While ensuring the sound insulation effect, it can also reduce the wear and scratches of the sound insulation blade 42 caused by friction such as stones and debris during the cleaning process, and can extend the service life of the equipment.

[0046] In order to reduce the situation where the blinds are subjected to external forces and gaps appear in rainstorms and typhoons, a pair of arc plates 44 are installed at the bottom of the sound insulation blades 42, and a buffer block is installed at the bottom of the arc plate 44, and a shock-absorbing block 45 is provided at the bottom of the buffer block. The shock-absorbing block 45 is hemispherical, and an adjusting rod 46 is inserted inside the shock-absorbing block 45. A pair of blocking strips 461 are installed on the adjusting rods 46 on both sides. The blocking strips 461 are located at both ends of the adjusting rods 46 and have a plurality of snap-in balls on the surface. The snap-in balls on the blocking strips 461 on both sides are staggered. When the edges of the sound insulation blades 42 abut against each other, the snap-in balls on the blocking strips 461 can be staggered with each other, which can play a limiting role and an auxiliary support role. The speed bump can also reduce the situation where rainwater and the like enter the room through the gaps when the sound insulation blades 42 are offset in angle due to strong winds or heavy rains.

[0047] In order to ensure the stability of the installation of the blinds, a fixed pad 11 is installed at the bottom of the fixed frame 1, and clamping plates 12 are provided at both ends of the top of the fixed pad 11. The clamping plates 12 are buckled in the transmission groove, and multiple mounting seats 13 are installed on the outer wall of the clamping plate 12. The mounting seats 13 are "L" shaped, and a pair of buffer rings 14 are provided on the mounting seats 13. The buffer rings 14 can reduce the damage to the installation wall and play a buffering role. When the installation position of the wall is inconsistent, multiple buffer rings 14 can be used for auxiliary installation.

[0048] Working principle: first, when it is necessary to isolate the external noise, the control motor 21 inside the drive box 2 can be used to operate, which can drive the rotating storage component 3 to move, thereby controlling the angular position of the noise reduction and silencing component 4, which can play a role of sealing and isolation, and can effectively isolate some noises. The noise reduction and silencing component 4 is easy to clean and maintain, and can reduce the dust accumulation that affects its noise reduction function. As the control motor 21 runs, the transmission rod 23 can be rotated, and the transmission belt 32 can be pulled to rotate. During the activity of the transmission belt 32, it can be pressed against the bottom of the buffer pressure plate 26, which can play a role of auxiliary positioning, ensuring stability during the transmission process and avoiding detachment cleaning. In the subsequent maintenance process, the buffer pressure plate 26 can be directly disassembled and cleaned to avoid the situation where internal dust accumulation causes the equipment to run jammed or the adjustment angle is inconsistent during the transmission process.

[0049] Then, during the movement of the conveyor belt 32, the friction force can be used to drive the docking shaft 35 to rotate, thereby driving the noise reduction and silencing component 4 to rotate, so that the two ends of the sound insulation blades 42 can be squeezed against each other, which can play a role in sealing and noise reduction. In addition, when encountering strong winds or heavy rain, the sound insulation blades 42 rotate and abut against each other, so that the blocking strips 461 can be staggered with each other, which plays a role in auxiliary limiting, and can further ensure stability, reduce the impact of abnormal weather, ensure the sound insulation efficiency of the blinds, and at the same time reduce the cleaning of water entering the room through the gap;

[0050] Finally, when the blinds need to be cleaned, the side with the mesh sheet 43 can be rotated inward to facilitate rinsing with clean water, so that the sound insulation blades 42 can be cleaned and maintained, and the mesh sheet 43 swings during the impact of clean water, which can squeeze the arc extension sheets on both sides of the sound insulation blades 42 to reduce dust residue, and when ventilation is needed, the sound insulation blades 42 can be arranged in parallel, and at the same time, the recovery belt 341 is driven to be rolled up under the action of the transmission rod 22, so that the sound insulation blades 42 can be stacked together for ventilation.
