Description

Technical Field

[0001] This utility model relates to the field of ventilation louver technology, specifically to a hidden frame sound-absorbing louver. Background Technology

[0002] To control noise transmission through wall ventilation louvers, noise reduction functions are added to the louvers, creating sound-absorbing ventilation louvers. Their structure typically consists of multiple louvered sound-absorbing panels, and the ventilation volume and noise reduction effect are controlled by adjusting the spacing and angle of the louvers.

[0003] For example, the decorative ventilation and sound-absorbing louver disclosed in Chinese Patent Publication No. CN220869259U is as follows: From top to bottom, the upper sound-absorbing louver 3 and the main sound-absorbing louver 4 are inserted between the support bracket 2 and into the first U-shaped clamp 7 and the second U-shaped clamp 8. At this time, by turning the screw head to rotate the threaded rod 17, the threaded rod 17 drives the insert block 15 to extend out of the rectangular barrel 14 and insert into the fixing hole 16 to form a fixation. Then, the second decorative strip 6 is placed on the front side of the support bracket 2, and the T-shaped cylindrical clip 9 passes through the insertion hole 11 through the long groove 10. The second decorative strip 6 is pressed down, causing the T-shaped cylindrical clip 9 to move to the bottom of the long groove 10. The T-shaped cylindrical clip 9 is limited by the clip protrusion 12, completing the assembly. During ventilation, the sound can be absorbed through the holes on the upper sound-absorbing louver 3 and the main sound-absorbing louver 4 and the internal filling material, thereby reducing noise. Simultaneously, the upper sound-absorbing louver 3 and the main sound-absorbing louver 4 can be disassembled by reversing the operation. However, it also has the following technical problems: After a period of use, dust easily accumulates on the sound-absorbing louvers, making them difficult to wipe clean. The long-term accumulation of dust reduces the gap between the louvers, thus reducing the sound-absorbing effect and also reducing the ventilation efficiency. Furthermore, the aforementioned structure requires rotating multiple threaded rods to disassemble the sound-absorbing louvers, making the disassembly process rather cumbersome. Utility Model Content

[0004] To address this issue, the present invention provides a frameless sound-absorbing louver to solve the problem of cumbersome disassembly steps for sound-absorbing louvers in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A frameless sound-absorbing louver, comprising a sound-absorbing louver body.

[0006] The sound-absorbing louver body is externally fitted with a limiting frame.

[0007] The limiting frame includes an outer frame, and limiting components one for limiting multiple sound-absorbing louver bodies are symmetrically installed on the left and right sides of the outer frame. A limiting component two is installed on one side of the limiting component one.

[0008] The limiting component includes a long rod, and the middle of the long rod is provided with multiple slots for placing the sound-absorbing louver body.

[0009] Furthermore, limit blocks are installed on both the left and right sides of one end of the sound-absorbing louver body.

[0010] Furthermore, the first slot is an inclined slot, and the first slot has a second slot for sliding of the limiting block, and the second slot has the same inclination angle as the first slot. The second slot has a third slot on both sides of the second slot.

[0011] Furthermore, a plurality of bolts for fixing the long rod to the outer frame are installed in the middle of the long rod.

[0012] Furthermore, the limiting member two includes a long rod two, and a wedge one is installed on the side of the long rod two facing the long rod one, and the wedge one is inserted into the slot one.

[0013] Furthermore, a second inclined block is installed on one side of the first inclined block, and the second inclined block is inserted into the second slot. A groove is provided on one side of the second inclined block to facilitate the deformation of the second inclined block. Both sides of the end of the second inclined block facing the first long rod are equipped with locking blocks that engage with the third slot.

[0014] This utility model has the following advantages: This utility model allows for regular dust cleaning during use. When cleaning dust, the second long rod can be pried out from one side of the first long rod, and then multiple sound-absorbing louvers can be pulled out from the first slot for cleaning. The disassembly of the sound-absorbing louvers is simple and convenient. The sound-absorbing louvers provided by this utility model are detachable, which facilitates cleaning the dust on the sound-absorbing louvers and avoids affecting the air circulation effect. After cleaning the sound-absorbing louvers, dust can be prevented from entering the room when the air is circulating. Attached Figure Description

[0021] Please see Figures 1-7 This utility model provides a hidden frame type sound-absorbing louver, including a sound-absorbing louver body 10. Limiting blocks 11 are fixedly installed on both the left and right sides of one end of the sound-absorbing louver body 10. A limiting frame 100 is installed on the outside of the sound-absorbing louver body 10. The limiting frame 100 includes an outer frame 110, and multiple sound-absorbing louver bodies 10 can be installed vertically and equidistantly inside the outer frame 110. The setting of multiple sound-absorbing louver bodies 10 facilitates noise reduction. In addition, the sound-absorbing louver body 10 provided by this utility model is detachable, which facilitates cleaning of dust on the sound-absorbing louver body 10 and avoids affecting the air circulation effect. After cleaning, the sound-absorbing louver body 10 can prevent dust from entering the room when the air is circulating.

[0022] The outer frame 110 is symmetrically equipped with limiting members 120 for limiting the multiple sound-absorbing louver bodies 10. The limiting member 120 includes a long rod 121. The long rod 121 has multiple slots 122 for placing the sound-absorbing louver bodies 10 at equal intervals in the middle. The slots 122 are inclined slots, so that the sound-absorbing louver bodies 10 placed in the slots 122 maintain a fixed angle and will not shake when blown by the wind, thus preventing abnormal noise.

[0023] The slot 122 has a slot 2 123 for sliding the limiting block 11, and the slot 2 123 has the same inclination angle as the slot 122. The slot 3 124 is provided on both sides of the slot 2 123. The long rod 121 has multiple bolts 125 installed in the middle for fixing the long rod 121 to the outer frame 110. The outer frame 110 has threaded holes. When fixing the long rod 121, the bolts 125 are screwed into the threaded holes on the inner wall of the outer frame 110, thereby fixing the long rod 121 to the outer frame 110, so that the multiple sound-absorbing louver bodies 10 can remain stable on the long rod 121.

[0024] One side of the limiting component 120 is fitted with a limiting component 2 130. The limiting component 2 130 includes a long rod 2 131. A wedge block 132 is fixedly installed on the side of the long rod 2 131 facing the long rod 121, and the wedge block 132 is inserted into the slot 122. A wedge block 2 133 is installed on one side of the wedge block 132, and the wedge block 2 133 is inserted into the slot 2 123. The wedge block 2 133 is fixed on one side of the long rod 2 131. Multiple wedge blocks 132 and wedge blocks 2 133 are vertically and equidistantly arranged on the side of the limiting component 2 130 facing the long rod 121.

[0025] One side of the inclined block 2 133 has a groove 135 to facilitate the deformation of the inclined block 2 133. Both sides of the end of the inclined block 2 133 facing the long rod 1 121 are fixedly installed with locking blocks 134 that engage with the locking slot 3 124. After the multiple sound-absorbing louver bodies 10 are placed in the locking slot 1 122, the long rod 2 131 can be installed on one side of the long rod 121, and the inclined block 1 132 is inserted into the locking slot 1 122, and the inclined block 2 133 is inserted into the locking slot 3 124. When the long rod 2 131 abuts against the long rod 1 121 in slot 2 123, the locking block 134 engages in slot 3 124, thereby locking the position of the long rod 2 131. When the long rod 2 131 is fixed, one side of the inclined block 1 132 abuts against one side of the sound-absorbing louver body 10, and one side of the inclined block 2 133 abuts against the limiting block 11, so that when the wind blows towards the sound-absorbing louver body 10, the sound-absorbing louver body 10 can remain stable.

[0026] This utility model allows for regular dust cleaning during use. When cleaning dust, the second long rod 131 can be pried out from one side of the first long rod 121, and then multiple sound-absorbing louver bodies 10 can be pulled out from the slots 122 for cleaning. The operation is relatively simple and convenient.

[0027] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
