Description

Technical Field

[0001] The utility model relates to the technical field of reading sound insulation boards, in particular to a assembled reading sound insulation board. Background Art

[0002] A library is an institution that collects, collates and stores books and materials for people to read and refer to. At the same time, a library is also a special place provided for readers to use documents in the library. It is necessary for users to keep the indoor quiet, and sound insulation boards are often used. The sound insulation board has the advantages of sound absorption, environmental protection, flame retardancy, heat insulation, heat preservation, moisture prevention, mildew prevention, easy dust removal, good stability, good impact resistance and so on.

[0003] At present, in order to install the sound insulation board in the library, it is necessary to first measure the size of the installation position of the sound insulation board, then customize the sound insulation board according to the size of the installation position, then place the customized sound insulation board at the installation position, and then connect two adjacent sound insulation boards, so as to complete the assembly and fixation of the sound insulation board. However, the existing sound insulation boards are all connected by screws. When splicing two adjacent sound insulation boards, it is necessary to install the screws through tools in the reserved holes opened on the outer wall of the sound insulation board, and then continuously rotate the screws until the outer wall of the screw fits with the outer wall of the sound insulation board. Although the splicing of two adjacent sound insulation boards can be realized, the splicing process is relatively cumbersome, increasing the time and energy required for splicing the sound insulation board. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an assembled reading sound insulation board, aiming to solve the problems in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an assembled reading sound insulation board, comprising:

[0006] A plurality of sound insulation boards;

[0007] A plurality of plug-in blocks, one end of which is fixedly connected to one end of the sound insulation board. A plurality of accommodation grooves adapted to the plug-in blocks are opened at the end of the sound insulation board far from the plug-in blocks. A limiting gear is rotatably installed in the inner cavity of the accommodation groove, and a plurality of teeth engaging with the limiting gear are fixedly installed at the top of the plug-in block;

[0008] A plurality of ratchets are rotatably installed on one side of the sound insulation board. A through hole communicating with the inner cavity of the accommodation groove is opened on the side of the sound insulation board close to the ratchet. One end of the ratchet is fixedly installed with a rotating shaft, and the end of the rotating shaft far from the ratchet penetrates through the through hole and is fixedly connected to one end of the limiting gear. A limiting member for positioning itself is arranged outside the ratchet. The rotated ratchet can be positioned by the limiting member, and the plug-in block inserted into the inner part of the accommodation groove can be positioned.

[0009] As a further description of the above technical solution:

[0010] The length of the plug-in block is not greater than the depth at which the accommodation groove is opened.

[0011] As a further description of the above technical solution:

[0012] A groove communicating with the inner cavity of the through hole is opened on one side of the sound insulation board, and the ratchet wheel is located in the inner cavity of the groove.

[0013] As a further description of the above technical solution:

[0014] The limiting member includes a clamping plate and a sliding rod. A sliding groove is opened on the inner wall of the groove away from its opening end. A sliding rod is slidably installed in the inner cavity of the sliding groove. One end of the sliding rod close to the opening end of the sliding groove penetrates through the sliding groove and extends into the inner cavity of the groove, and a clamping plate that is rotationally installed through a torsion spring on the outer wall of the sliding rod and engages with the ratchet wheel.

[0015] As a further description of the above technical solution:

[0016] A plurality of guide blocks are fixedly installed on the outer wall of the sliding rod in an annular distribution, and a plurality of guide grooves adapted to the guide blocks are opened on the inner wall of the sliding groove in an annular distribution.

[0017] As a further description of the above technical solution:

[0018] A magnet for adsorbing the sliding rod is fixedly installed on the inner wall of the sliding groove away from its opening end.

[0019] As a further description of the above technical solution:

[0020] A sealing cap is detachably installed in the inner cavity of the groove.

[0021] The utility model has the following beneficial effects:

[0022] In the utility model, after the plug-in block is inserted into the accommodation groove, the limiting gear rotates along its own axis under the action of the teeth, and the ratchet wheel rotates along the same direction as the limiting gear. After the limiting gear stops rotating, the limiting member engages with the outer wall of the ratchet wheel. At this time, the ratchet wheel cannot rotate in the reverse direction under the action of the limiting member. Therefore, when one of the sound insulation boards after splicing is stressed, due to the inability of the limiting gear to rotate, the plug-in block cannot be detached from the inside of the accommodation groove, and the fixed connection of the spliced sound insulation boards can be realized, reducing the complexity, as well as the time and energy required for assembling the sound insulation boards.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1-6 , an embodiment provided by the present utility model: a prefabricated reading sound insulation board, comprising:

[0033] Multiple sound insulation boards 1. By splicing multiple sound insulation boards 1 with each other, a barrier can be formed for the propagation of sound, thereby blocking the propagation of sound and absorbing sound waves, so as to achieve the purpose of reducing noise inside the library.

[0034] Multiple plug-in blocks 3, one end of which is fixedly connected to one end of the sound insulation board 1. A plurality of accommodating grooves 7 adapted to the plug-in blocks 3 are formed at the end of the sound insulation board 1 away from the plug-in blocks 3. When two sound insulation boards 1 need to be spliced together, the plug-in block 3 at one end of one of the sound insulation boards 1 is inserted into the inner cavity of the accommodating groove 7 until the inserted end of the plug-in block 3 fits against the inner wall of the accommodating groove 7 away from its own opening end, and the preliminary connection of the two sound insulation boards 1 can be achieved.

[0035] A limiting gear 6 is rotatably installed in the inner cavity of the accommodation groove 7. A plurality of teeth 4 that are engaged with the limiting gear 6 are fixedly installed at the top of the insertion block 3. When one end of the insertion block 3 is inserted into the interior of the accommodation groove 7, the teeth 4 come into contact with the limiting gear 6 and cause the limiting gear 6 to rotate until the limiting gear 6 and the teeth 4 are engaged with each other.

[0036] A plurality of ratchets 5 are rotatably installed on one side of the sound insulation board 1. Through holes communicating with the inner cavity of the accommodation groove 7 are provided on the side of the sound insulation board 1 close to the ratchet 5. One end of the ratchet 5 is fixedly installed with a rotating shaft. The end of the rotating shaft away from the ratchet 5 penetrates through the through hole and is fixedly connected with one end of the limiting gear 6. A limiting member for positioning itself is arranged outside the ratchet 5. The rotated ratchet 5 can be positioned through the limiting member, and the insertion block 3 inserted into the interior of the accommodation groove 7 can be positioned. When the limiting gear 6 rotates along its own axis under the action of the teeth 4, the ratchet 5 rotates along the same direction with the limiting gear 6. After the limiting gear 6 stops rotating, the limiting member is engaged with the outer wall of the ratchet 5. At this time, the ratchet 5 cannot rotate in the reverse direction under the action of the limiting member. Thus, when one of the spliced sound insulation boards 1 is stressed, due to the inability of the limiting gear 6 to rotate, the insertion block 3 cannot be separated from the interior of the accommodation groove 7, and the fixed connection of the spliced sound insulation boards 1 can be realized, reducing the complexity of assembling the sound insulation board 1, as well as the time and energy required.

[0037] Since there is a large flow of people in the library, it is easy to cause abrasion to the sound insulation board 1 when people move in the library, resulting in the sound insulation board 1 being extremely prone to damage. The damaged sound insulation board 1 is neither beautiful nor has a reduced noise reduction effect, so the sound insulation board 1 needs to be regularly inspected and replaced.

[0038] When the damaged sound insulation board 1 needs to be replaced, the limiting member is separated from the ratchet 5, and then one of the sound insulation boards 1 is pulled until the insertion block 3 is withdrawn from the interior of the accommodation groove 7, and the separation of two adjacent sound insulation boards 1 can be realized, improving the replacement rate of the damaged sound insulation board 1.

[0039] The length of the insertion block 3 is less than the depth of the accommodation groove 7. After the insertion block 3 is completely inserted into the inner cavity of the accommodation groove 7, two adjacent sound insulation boards 1 are in close contact with each other, reducing the distance between two adjacent sound insulation boards 1, thereby increasing the sound absorption and noise reduction effects of the sound insulation board 1.

[0040] A groove communicating with the inner cavity of the through hole is provided on one side of the sound insulation board 1. The ratchet 5 is located in the inner cavity of the groove. The diameter of the groove is greater than the outer diameter of the ratchet 5, allowing the ratchet 5 to rotate completely in the inner cavity of the groove, preventing the ratchet 5 from being exposed and damaged.

[0041] A sliding groove 11 is provided in the inner wall of the groove away from its own opening end. A sliding rod 8 is slidably installed in the inner cavity of the sliding groove 11. One end of the sliding rod 8 close to the opening end of the sliding groove 11 penetrates through the sliding groove 11 and extends into the inner cavity of the groove. When the sliding rod 8 slides along its own axis direction, it can play a role in limiting the sliding trajectory of the sliding rod 8, preventing the sliding rod 8 from shifting when moving back and forth along its own axis direction.

[0042] A clamping plate 12 that engages with a ratchet wheel 5 is rotatably installed on the outer wall of the sliding rod 8 through a torsion spring. A through hole communicating with the other side of the clamping plate 12 is provided on one side of the clamping plate 12. The clamping plate 12 is sleeved outside the sliding rod 8 through the through hole. At the same time, a torsion spring is sleeved on the outer wall of the sliding rod 8. One end of the torsion spring is fixedly connected to the inner wall of the through hole. When the plug-in block 3 is inserted into the inner part of the accommodating groove 7 and causes the limiting gear 6 to rotate, the ratchet teeth on the outer wall of the ratchet wheel 5 contact the outer wall of the clamping plate 12 and apply an external force to the clamping plate 12, causing the clamping plate 12 to rotate away from the ratchet wheel 5 with the axis direction of the sliding rod 8 as the rotation center. At this time, the end of the torsion spring connected to the inner wall of the through hole rotates accordingly, causing the torsion spring to be compressed. When the clamping plate 12 is located between two ratchet teeth, one end of the clamping plate 12 and the ratchet teeth are disengaged and the torsion spring is reset. When the ratchet wheel 5 rotates in the reverse direction, the end of the clamping plate 12 fits against the outer wall of the ratchet teeth, so that the ratchet wheel 5 can be limited, and the rotation direction of the limiting gear 6 can be restricted, preventing the limiting gear 6 from resetting, thereby fixing the plug-in block 3 in the inner part of the accommodating groove 7.

[0043] When it is necessary to separate the plug-in block 3 from the inner part of the accommodating groove 7, the sliding rod 8 is pulled along the axis direction of the sliding rod 8 until the clamping plate 12 is disengaged from between two adjacent ratchet teeth, so that the limit on the ratchet wheel 5 can be released, allowing the ratchet wheel 5 to rotate in the reverse direction, thereby enabling the plug-in block 3 to be separated from the inner part of the accommodating groove 7, which is beneficial to realizing the separation of two adjacent sound insulation boards 1.

[0044] A plurality of guide blocks 10 are fixedly installed on the outer wall of the sliding rod 8 in a circular distribution. A plurality of guide grooves adapted to the guide blocks 10 are provided on the inner wall of the sliding groove 11 in a circular distribution, enabling the sliding rod 8 to only move back and forth along its own axis direction through the sliding groove 11, preventing the sliding rod 8 from rotating when the clamping plate 12 rotates, so as to facilitate the repeated rotation of the clamping plate 12.

[0045] A magnet 9 for adsorbing the sliding rod 8 is fixedly installed on the inner wall of the sliding groove 11 away from its own opening end. When the clamping plate 12 is located between two ratchet teeth, one end of the sliding rod 8 fits against one end of the magnet 9, so that the sliding rod 8 can be adsorbed, improving the stability when the clamping plate 12 engages with the ratchet wheel 5.

[0046] A sealing cap 2 is detachably installed in the inner cavity of the groove. After the sound insulation board 1 is connected, one end of the sealing cap 2 is inserted into the groove. At this time, the outer wall of the sealing cap 2 is in close contact with the inner wall of the groove until one end of the sealing cap 2 is in contact with the inner wall of the groove far from its own opening end. At this time, the sliding rod 8 and the ratchet wheel 5 are inserted into the sealing cap 2, thereby improving the aesthetics of the sound insulation board 1.

[0047] The sealing cap 2 is made of rubber material, which improves the friction between the sealing cap 2 and the inner wall of the groove and improves the stability of the sealing cap 2 inside the groove.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
