[0002] Audio is very common in modern daily life and production. Different audio systems are used for different usage scenarios. For example, ships are generally equipped with specific audio equipment to warn the surroundings, thereby assisting the driver to complete the normal driving task of the ship.
[0003] When existing marine audio systems are in use, many of them are installed on matching columns. However, during the application process, there is often no corresponding buffering and shock-absorbing part during the installation process or only traditional gaskets are used to achieve the buffering and shock-absorbing function, which results in insufficient buffering and shock-absorbing effect and easily shortens the service life due to long-term bumps and vibrations. Utility Model Content
[0004] The utility model aims to provide a buffer mechanism for installing a marine audio system, which solves one of the above-mentioned problems by adding an elastic part with a specific shape and filled with compressed air.
[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The outer side of the external threaded barrel is uniformly penetrated by movable rods, and an elastic member is installed on the side of the movable rod close to the mounting column, and an extrusion block is installed on the side of the movable rod away from the mounting column, and a first spring is connected between the extrusion block and the external threaded barrel;
[0009] The external threaded barrel is provided with an operating mechanism for extruding the extrusion block.
[0010] As a further solution of the utility model: the movable rod and the extrusion block are made in one piece, and the movable rod and the external threaded cylinder form a sliding structure.
[0011] As a further solution of the utility model: the side cross-section shape of the elastic member is trapezoidal, and the cross-section shape of the elastic member is arc-shaped, the elastic member is hollow, and the interior of the elastic member is filled with compressed air.
[0012] As a further solution of the utility model: the operating mechanism includes an internal thread ring, the internal thread ring is sleeved on the outside of the external thread barrel, and an extrusion ring is installed at the bottom of the internal thread ring.
[0013] As a further solution of the utility model: the operating mechanism includes a threaded rod, the central axis of the internal threaded ring coincides with the central axis of the external threaded barrel, and the internal threaded ring and the external threaded barrel are threadedly connected.
[0014] As a further solution of the utility model: the operating mechanism also includes multiple groups of operating columns, and the multiple groups of operating columns are evenly installed on the top of the internal threaded ring, the outer side of the operating column is provided with a limit plate, and the limit plate extends to the inside of the limit groove, a second spring is connected between the limit plate and the operating column, and a connecting ring is installed on the top of the limit plate.
[0015] As a further solution of the utility model: the side cross-section of the limit plate is in an "L" shape, and the limit plate is slidably connected to the operating column.
[0016] Beneficial effects of the utility model:
[0017] (1) The side cross-section of the elastic member and the trapezoidal groove are both trapezoidal, so that there is a multi-directional small elastic space between the mounting column and the external threaded tube, rather than being limited to a buffering effect in one direction. At the same time, the elastic member is filled with compressed air, which can further reduce the conduction of vibration, thereby greatly increasing the buffering and shock absorption effect;
[0018] (2) Through the threaded connection between the internal thread ring and the external thread barrel, during installation, the worker can drive the extrusion ring to squeeze multiple groups of elastic members into the corresponding trapezoidal grooves by rotating a group of internal thread rings, which is convenient and quick to operate;
[0019] (3) The operating column, the limiting plate and the second spring are arranged on the internal thread ring, so that after the installation is completed, the limiting plate can be inserted into the corresponding limiting groove, thereby limiting the rotation of the internal thread ring and the external thread barrel, thereby fully ensuring the stability of the installation;
[0020] (4) The side cross-section of the elastic member and the trapezoidal groove is trapezoidal, and after installation, there is still a certain distance between the elastic member and the side wall near the middle of the trapezoidal groove. Therefore, when the elastic member is worn out after a period of use, the elastic member can be further extended into the trapezoidal groove to stabilize the external threaded tube by continuing to rotate the internal thread ring without the need for complete disassembly or maintenance. This makes the structure more suitable for situations where it is inconvenient to repair or purchase spare parts when the ship is not docked. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1-Figure 4As shown, the utility model is a buffer mechanism for installing a marine audio system, comprising a mounting column 1, a trapezoidal groove 2 is evenly provided on the outer side of the mounting column 1, and an external threaded tube 3 is provided on the outer side of the mounting column 1, a sound body 4 is installed on one side of the outer wall of the external threaded tube 3, and a limiting groove 5 is evenly provided on the top of the external threaded tube 3, and the sound body 4 is the same as the existing marine audio system, which will not be described in detail here;
[0032] like Figure 2 and Figure 3 As shown, the outer side of the external threaded barrel 3 is uniformly penetrated by a movable rod 6, and an elastic member 7 is installed on the side of the movable rod 6 close to the mounting column 1, and an extrusion block 8 is installed on the side of the movable rod 6 away from the mounting column 1, and a first spring 9 is connected between the extrusion block 8 and the external threaded barrel 3, the movable rod 6 and the extrusion block 8 are made in one piece, and the movable rod 6 and the external threaded barrel 3 form a sliding structure, so that when the hypotenuse of the extrusion block 8 is squeezed from above, the movable rod 6 and the elastic member 7 can be driven to squeeze into the inside of the trapezoidal groove 2, so that after the installation is completed, the elastic member 7 and the movable rod 6 can The external threaded tube 3 is fixed on the mounting column 1 in cooperation with the trapezoidal groove 2. At the same time, the elastic member 7 can be slightly deformed during use to reduce the conduction of vibration, thereby playing the role of buffering and shock absorption. After the elastic member 7 is completely squeezed into the interior of the trapezoidal groove 2, there is still a certain distance between the end of the elastic member 7 close to the mounting column 1 and the side close to the middle position of the interior of the trapezoidal groove 2. As a result, when the elastic member 7 is worn out after being used for a period of time, the elastic member 7 can continue to penetrate deeper into the interior of the trapezoidal groove 2 by continuing to squeeze the extrusion block 8 to ensure the stability of the installation of the external threaded tube 3.
[0033] Optionally, the elastic member is a rubber elastic member.
[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the side cross-sectional shape of the elastic member 7 is a trapezoid, and the cross-sectional shape of the elastic member 7 is an arc. The elastic member 7 is hollow inside, and the interior of the elastic member 7 is filled with compressed air, so that during the vibration conduction process, in addition to the elastic member 7 itself slightly deforming to reduce the vibration conduction, the compressed air inside the elastic member 7 can also be further compressed to cooperate in completing the task of reducing the vibration conduction.
[0035] like Figure 1As shown, an operating mechanism for extruding the extrusion block 8 is provided on the externally threaded barrel 3, and the operating mechanism includes an internally threaded ring 10, which is sleeved on the outside of the externally threaded barrel 3, and an extrusion ring 11 is installed at the bottom of the internally threaded ring 10, the central axis of the internally threaded ring 10 coincides with the central axis of the externally threaded barrel 3, and the internally threaded ring 10 and the externally threaded barrel 3 are threadedly connected, so that during installation, the staff can release the rotation restriction of the internally threaded ring 10 and rotate the internally threaded ring 10 to make the extrusion ring 11 move downward to extrude multiple groups of extrusion blocks 8, and the operation is convenient and quick.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the operating mechanism also includes multiple groups of operating columns 12, and the multiple groups of operating columns 12 are evenly installed on the top of the internal thread ring 10. The outer side of the operating column 12 is sleeved with a limit plate 13, and the limit plate 13 extends to the inside of the limit groove 5. A second spring 14 is connected between the limit plate 13 and the operating column 12, and a connecting ring 15 is installed on the top of the limit plate 13. The side cross-section shape of the limit plate 13 is "L" shaped, and the limit plate 13 and the operating column 12 are slidably connected, so that during the operation, the staff only needs to hold any The two groups of operating columns 12 are close to the outer side of the bottom end and push the limit plate 13 upwards, so that multiple groups of limit plates 13 can leave the corresponding limit grooves 5 at the same time to release the rotation restriction of the internal threaded ring 10 and the external threaded tube 3. Maintaining the above state can complete the rotation task of the internal threaded ring 10 without affecting the convenience of operation. At the same time, after the installation is completed, the limit plate 13 can be inserted into the corresponding limit groove 5, thereby limiting the rotation of the internal threaded ring 10 and the external threaded tube 3, thereby ensuring the stability of the installation and avoiding loosening.
[0037] The bottom of the mounting column 1 is fixed to the hull by welding or the like, and the sound body 4 is fixed to the external threaded tube 3 by welding or the like. During installation, the external threaded tube 3 is slightly screwed onto the external threaded tube 3. At this time, the limiting plate 13 is still at a certain distance from the limiting groove 5 to keep the external threaded tube 3 on the outside of the mounting column 1, and ensure that the elastic member 7 is basically aligned with the corresponding trapezoidal groove 2. Then, the internal threaded ring 10 continues to be screwed onto the external threaded tube 3, and the extrusion ring 11 begins to squeeze the extrusion block 8. Through the sliding and connection of the movable rod 6 and the external threaded tube 3, and the elasticity of the first spring 9, the movable rod 6 can drive the elastic member 7 to gradually insert into the interior of the trapezoidal groove 2 until the bottom of the limiting plate 13 begins to contact the external threaded tube 3. At this time, the elastic member 7 has been partially inserted into the trapezoidal groove 2, so that the external threaded tube 3 can be basically restricted on the installation column 1. Then, hold any two sets of operating columns 12 and squeeze the limit plates 13 on them upward. The connection between the multiple sets of limit plates 13 is provided with a connecting ring 15, so that the multiple sets of limit plates 13 can move upward at the same time. Maintaining this state, continue to rotate the internal threaded ring 10 onto the external threaded tube 3, and the extrusion ring 11 continues to squeeze the extrusion block 8 until the hypotenuse of the elastic member 7 is fully squeezed with the hypotenuse inside the trapezoidal groove 2. Then, release the operating column 12 and the limit plate 13, and the second spring 14 drives the limit plate 13 to be inserted into the corresponding limit groove 5, so as to limit the rotation of the internal threaded ring 10 and the external threaded tube 3, thereby ensuring the stability after installation.
[0038] In the subsequent use process, due to the elasticity of the elastic member 7 itself and the compressed air filled in the elastic member 7, when the vibration is transmitted, the elastic member 7 and the compressed air can be deformed accordingly, thereby reducing the transmission amplitude of the vibration, thereby achieving a buffering and shock absorbing effect;
[0039] When the elastic member 7 becomes loose due to wear due to long-term use, the staff can continue to rotate the internal threaded ring 10 downward according to the above operation method, so that the elastic member 7 is further squeezed and inserted into the trapezoidal groove 2 to offset the worn part, thereby continuing to achieve a stable installation.
[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
