Description

Technical Field

[0001] This utility model relates to the field of noise reduction equipment technology, specifically to a noise reduction cabinet. Background Technology

[0002] Soundproof cabinets, as devices that effectively block equipment operating noise, are widely used in various places requiring a quiet environment. Most existing soundproof cabinets employ multi-layered composite structures for their cabinet bodies and doors, with the sound-absorbing cotton layer being a key component for achieving the soundproofing effect. However, the sound-absorbing cotton's sound absorption performance deteriorates after prolonged use, requiring periodic replacement.

[0003] Currently, the sound-absorbing cotton in traditional soundproof cabinets is usually fixed to the cabinet body, cabinet door or partition by means of pasting, welding or riveting. When replacing it, the outer or inner layer of the board needs to be removed. The operation is cumbersome and time-consuming, and it is easy to damage the cabinet structure, which increases the maintenance cost and difficulty. Summary of the Invention

[0004] The technical problem to be solved by this utility model is how to solve the problems of difficulty in replacing sound insulation cotton, cumbersome operation, and easy damage to the cabinet structure in existing soundproof cabinets.

[0005] The technical solution adopted by this utility model is as follows: a silent cabinet, including a cabinet body and a cabinet door rotatably connected to the cabinet body. The cabinet body is provided with at least one sound insulation part. The sound insulation part includes a sound insulation cavity, a slide rail and a mounting frame. The slide rail is disposed inside the sound insulation cavity. The mounting frame is slidably connected to the slide rail. The inner wall of the sound insulation cavity is provided with a groove. A limiting member is rotatably connected in the groove. Multiple circular grooves are provided on both the groove and the limiting member. A first elastic member is installed in the circular groove. A fixing plate connected to the cabinet body is provided at the opening of the sound insulation cavity.

[0006] The above structure has the following beneficial effects:

[0007] (1) The cabinet has at least one sound insulation section inside. The number of sound insulation sections can be flexibly adjusted according to actual needs to adapt to different sizes and different noise levels of the usage scenarios. At the same time, the sound insulation cavity serves as an independent space for the sound insulation cotton, which can separate the sound insulation cotton from the equipment installation area inside the cabinet, prevent the sound insulation cotton from shifting and falling into the equipment area to affect the operation of the equipment, and also facilitate the maintenance of the sound insulation cotton in the later stage.

[0008] (2) The slide rail in the sound insulation cavity and the sliding connection of the installation frame form a "pull-out" structure. The sound insulation cotton can be accessed simply by pulling out the installation frame along the slide rail. This solves the problem that traditional sound insulation cabinets require disassembling the cabinet panel and damaging the integrity of the cabinet to replace the sound insulation cotton. Moreover, the sliding connection method has low resistance, and a single person can complete the picking and putting of the installation frame.

[0009] (3) The fixing plate at the opening of the sound insulation board can realize the quick opening and closing of the sound insulation cavity. When the sound insulation cotton needs to be replaced, the fixing plate can be opened to expose the installation frame. During daily use, the fixing plate can close the opening of the sound insulation cavity to reduce dust, water vapor and foreign objects from entering the sound insulation cavity and prevent dust from adhering to the surface of the sound insulation cotton and reducing the sound absorption effect.

[0010] (4) By setting a groove in the inner wall of the sound insulation cavity and rotating the limiting member in the groove, and setting multiple circular grooves on the groove and the limiting member, and installing the first elastic member in the circular groove, the first elastic member provides elastic force to the limiting member, so that the limiting member can limit the position of the mounting frame, preventing the mounting frame from sliding off the slide rail when the cabinet is moved or the equipment is running and vibrating, ensuring that the sound insulation cotton is in contact with the inner wall of the sound insulation cavity, and avoiding the decrease in sound insulation effect due to the displacement of the mounting frame; in addition, when it is necessary to remove the mounting frame, it is only necessary to press the limiting member to compress the elastic member, so that the limiting member can rotate and thus release the obstruction to the mounting frame. There is no need to remove the limiting structure, which is convenient to operate and will not damage the limiting member or the groove.

[0011] Preferably, a cover plate is fixed to the opening of the mounting frame by locking bolts.

[0012] By installing a cover plate at the opening of the mounting frame, the sound-absorbing cotton can be stably fixed inside the mounting frame, preventing the sound-absorbing cotton from shifting during cabinet use and ensuring good sound insulation. The locking bolts are easy to disassemble, which, compared with welding, can ensure reliable fixing and quick replacement of the sound-absorbing cotton, simplifying the operation process and avoiding damage to the mounting frame during disassembly.

[0013] Preferably, the sound insulation part is arranged on the top and bottom surfaces, left and right sides, and inside the cabinet away from the cabinet door.

[0014] By placing sound insulation components in different locations inside the cabinet, the cabinet achieves all-around sound insulation, significantly improving the sound insulation effect and solving the problem of incomplete sound insulation areas in traditional silent cabinets.

[0015] Preferably, the fixing plate is provided with a handle.

[0016] By installing handles on the fixed plate, it is easy to remove the fixed plate without having to pry the edge of the sound insulation cavity opening to remove the fixed plate, thus avoiding damage to the connection structure between the fixed plate and the cabinet, such as the magnetic surface, due to external forces.

[0017] Preferably, the mounting frame is connected to the slide rail via a horizontal slider and a vertical slider. The mounting frame has rotating shafts on both sides, which are rotatably connected to the vertical slider, and the vertical slider is slidably connected to the horizontal slider.

[0018] The multi-directional sliding connection between the horizontal and vertical sliders allows the mounting frame to move bidirectionally along the slide rail and perpendicular to the slide rail, facilitating the adjustment of the distance between the mounting frame and the inner wall of the sound insulation cavity. At the same time, the mounting frame and the vertical slider are rotatably connected, so the mounting frame can also be angled.

[0019] Preferably, the slide rail has a boss at the end away from the cabinet door, the boss is rotatably connected to a rotating member, and a second elastic member is provided at the connection between the rotating member and the boss.

[0020] The rotating component is rotatably connected to the boss, and a second elastic element is set at the connection between the two. This allows the rotating component to continuously push the mounting frame towards the inner wall of the sound insulation cavity as the mounting frame is pushed forward, until the mounting frame fits against the inner wall of the sound insulation cavity. When the mounting frame is removed, the rotating component will automatically reset under the action of the second elastic element, eliminating the need for manual repositioning of the rotating component, reducing operation steps, improving replacement efficiency, and preventing the rotating component from interfering with the mounting frame during the next installation due to failure to reset, thus ensuring the reliability of the structure.

[0021] Preferably, a first limiting rod is provided on one side of the boss.

[0022] A first limiting rod is set on one side of the boss to limit the maximum rotation angle of the rotating part under the action of the second elastic element. This prevents the rotating part from rotating excessively due to the excessive elastic force of the second elastic element, which would prevent the subsequent installation frame from properly contacting the rotating part. At the same time, it ensures that the rotating part stays in the preset position after resetting.

[0023] Preferably, a second limiting rod is provided on the side wall of the groove.

[0024] The second limiting rod on the side wall of the groove can limit the rotation range of the limiting member, preventing the limiting member from rotating excessively under the action of the elastic force of the first elastic member, which would result in the inability to effectively limit the mounting frame. At the same time, it ensures that the limiting member is always kept within a reasonable rotation range that can be quickly contacted by pressing, thus ensuring the reliability of the limiting and unlocking operations.

[0025] Preferably, the slide rail is connected to a frame limiting component at one end near the cabinet door. The frame limiting component includes a screw, a knob, and an abutment block. One end of the screw is threaded, the knob is fixedly connected to the screw, and the abutment block is rotatably connected to the other end of the screw.

[0026] The frame limiting component can be rotated by turning the knob. When the frame limiting component is tightened, the abutment block abuts against the top surface of the mounting frame. The mounting frame can be fixed without tools. The rotational connection between the abutment block and the screw can prevent the abutment block from rotating along with the knob.

[0027] Preferably, the contact area between the transverse slider and the rotating component is provided with rounded corners.

[0028] By setting rounded corners at the contact points between the horizontal slider and the rotating component, frictional resistance and jamming during their relative movement can be reduced, making the installation frame move more smoothly and avoiding jamming and wear caused by sharp contact points. At the same time, the rounded corners can also prevent deformation and breakage of the contact points of the slider or rotating component, further extending the service life of the components.

Detailed Implementation

[0040] The following will be combined with the appendix Figure 1-9 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Example

[0043] The following description, in conjunction with specific embodiments, provides further details. Figure 1-9 As shown, this embodiment is a soundproof cabinet, including a cabinet body 1 and a cabinet door 2 rotatably connected to the cabinet body 1. At least one soundproofing section is provided inside the cabinet body 1. In this embodiment, multiple soundproofing sections are provided, respectively located on the top surface, bottom surface, left and right sides, and at a position away from the cabinet door 2 inside the cabinet body 1. Each soundproofing section includes a soundproofing cavity 101, a slide rail 1011, and a mounting frame 1014. The opening of the soundproofing cavity 101 is provided with a fixing plate 102 fixed by magnetic attraction. The slide rail 1011 is located inside the soundproofing cavity 101, and the mounting frame 1014... It is also slidably connected to the slide rail 1011. A groove 1012 is provided on the inner wall of the sound insulation cavity 101. A limiting member 1013 is rotatably connected in the groove 1012. Multiple circular grooves 9 are provided on both the groove 1012 and the limiting member 1013. A first elastic member 10 is installed in the circular groove 9. The first elastic member 10 is a compression spring, which is used to provide elastic force for the limiting member 1013 to limit the mounting frame 1014 that is slidably installed to the designated position. In addition, a cover plate 1015 is installed at the opening of the mounting frame 1014 by locking bolts 12.

[0044] The mounting frame 1014 and the slide rail 1011 are connected by a horizontal slider 3 and a vertical slider 4. Rotating shafts are provided on both sides of the mounting frame 1014, and the rotating shafts are rotatably connected to the vertical slider 4. The horizontal slider 3 is connected to the slide rail 1011, and the vertical slider 4 is connected to the horizontal slider 3, thereby realizing the angle adjustment of the mounting frame 1014 during installation and the positional movement perpendicular to the inner wall of the sound insulation cavity 101.

[0045] A boss 5 is provided at the end of the slide rail 1011 away from the cabinet door 2. A rotating member 6 is rotatably connected to the boss 5, and a second elastic member is provided at the connection between the rotating member 6 and the boss 5. The second elastic member is installed on the rotating shaft of the rotating member 6 and is a torsion spring for resetting the rotating member 6. When the mounting frame 1014 abuts against the rotating member 6 and drives the rotating member 6 to rotate, the other end of the rotating member 6 will gradually abut against the top surface of the mounting frame 1014, causing the position of the mounting frame 1014 to move, thereby abutting the mounting frame 1014 against the inner wall of the sound insulation cavity 101. At the same time, due to the second elastic member... The design of the mounting components facilitates the automatic reset of the rotating component 6 after the mounting frame 1014 is removed. To prevent the rotating component 6 from rotating too much under the action of the torsion spring after the mounting frame 1014 is removed, a first limiting rod 7 is provided on one side of the boss 5. When the rotating component 6 rotates to a certain position under the action of the torsion spring, it will be blocked by the first limiting rod 7, ensuring that the rotating component 6 can rotate to the preset position. In addition, the part where the horizontal slider 3 contacts the rotating component 6 is rounded. A limiting plate 13 is also provided on the side of the slide rail 1011 away from the cabinet door 2 to prevent the mounting frame 1014 from being pushed too far during installation.

[0046] To prevent the rotation range of the limiting component 1013 from being too large, a second limiting rod 8 is provided on the side wall of the groove 1012. In addition, a frame limiting component 11 is threadedly connected to the end of the slide rail 1011 near the cabinet door 2. The frame limiting component 11 is mainly composed of a screw, with a threaded end and a knob for rotation in the middle. The knob is fixed to the screw by welding, while the other end of the screw is an abutment block. The abutment block is rotatably connected to the screw. When the mounting frame 1014 is adjusted to a suitable position, the frame limiting component 11 can be installed. As the knob is continuously rotated, the frame limiting component 11 is fixed. At the same time, the abutment block on the frame limiting component 11 will also abut against the top surface of the mounting frame 1014, thereby limiting the mounting frame 1014.

[0047] Working principle:

[0048] When it is necessary to replace the sound insulation cotton in the sound insulation cavity 101, open the cabinet door 2, then remove the fixing plate 102 on the sound insulation cavity 101, then remove the frame limiting component 11 set on the slide rail 1011 in the sound insulation cavity 101, and then press the limiting member 1013 set in the sound insulation cavity 101 so that the top surface of the limiting member 1013 is flush with the inner wall of the sound insulation cavity 101. At this time, the mounting frame 1014 can be pulled outward. After the mounting frame 1014 is removed, remove the cover plate 1015 installed on the mounting frame 1014, and then replace the sound insulation cotton in the mounting frame. At this time, since the mounting frame 1014 has been removed, the rotating part 6 rotatably connected to the boss 5 will return to the preset position under the action of the torsion spring.

[0049] If you do not want to remove the mounting frame 1014, you can directly remove the cover plate 1015 on the mounting frame 1014 and then remove the sound insulation cotton. However, doing so may cause dust and other debris to fall into the sound insulation cavity 101.

[0050] After replacing the sound-absorbing cotton, insert the end of the mounting frame 1014 with the vertical slider 4 into the groove of the horizontal slider 3. Then, try to make the mounting frame 1014 parallel to the inner wall of the sound insulation cavity 101. Push the mounting frame 1014 until one end of the mounting frame 1014 abuts against the rotating member 6. At this time, as the mounting frame 1014 moves continuously, the other end of the rotating member 6 abuts against the top surface of the mounting frame 1014, thereby causing the mounting frame 1014 to move in a direction perpendicular to the inner wall of the sound insulation cavity 101 until the two abut against each other. At this time, the limiting member 1013 located in the groove 1012 will rotate under the action of the first elastic member 10 until it abuts against the bottom edge of the mounting frame 1014. Then, the frame limiting component 11 on the slide rail 1011 can be installed to further limit the mounting frame 1014.
