[0002] A sofa is a type of furniture that is usually placed in living rooms, lounges, and other areas for people to sit or lie down and rest. Sofas typically consist of a seat cushion, shock-absorbing springs, backrests, and armrests. When a user sits on a sofa to rest, the shock-absorbing springs provide a soft sitting or lying experience.

[0003] In the present technology, common sofas usually provide users with a comfortable service experience through soft cushions and internal elastic devices. The elastic devices inside the sofa are usually provided by springs. When using a sofa, some people will choose a firm sofa or a soft sofa according to their different preferences. However, existing sofas cannot adjust the firmness when sitting according to the user's preferences, which is not conducive to other groups. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a vibration-damping sofa.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-damping sofa, comprising a base, two sets of armrests fixedly connected to both sides of the base, a backrest fixedly connected to one side of the base, a round rod rotatably connected to one side of the inner wall of the base, the round rod passing through the base and the armrests, a first bevel gear fixedly connected to one end of the round rod, a second bevel gear meshing with the bottom of the first bevel gear, a second gear fixedly connected to the bottom of the second bevel gear, the second gear rotatably connected to the bottom of the inner wall of the base, a first gear meshing with one side of the second gear, a threaded hole formed in the inner wall of the first gear, a first threaded rod fixedly connected to the center of the inner wall of the base, the first gear being threadedly connected to the outer wall of the first threaded rod through the threaded hole, a mounting plate fixedly connected to the inner wall of the base, a spring fixedly connected to the top of the mounting plate, a top plate fixedly connected to the top of the spring, a seat cushion fixedly connected to the top of the top plate, a second threaded rod fixedly connected to the center of the bottom of the top plate, the second threaded rod being disposed at the top of the first threaded rod, a round hole formed in the center of the mounting plate, and the second threaded rod being disposed within the round hole.

[0010] The technical effects and advantages of this vibration-damping sofa:

[0011] By incorporating a seat cushion, users can comfortably sit or lie on the sofa. When a user sits on the cushion, it creates downward pressure. As the cushion and top panel move downwards, they compress the springs. Since there are multiple sets of springs, the compression also generates an upward restoring force, providing a soft and comfortable experience. When a firmer sofa is desired, the round rod can be rotated to drive the first bevel gear, the second bevel gear, the second gear, and the first gear. Because the inner wall of the first gear has a threaded groove, the first gear gradually moves upwards on the first threaded rod as it rotates, until the top of the threaded groove of the first gear gradually slides into the bottom of the second threaded rod. At this point, the top and bottom of the first gear are connected to the second threaded rod and the first threaded rod, respectively, thus fixing the positions of the second threaded rod, the top panel, and the seat cushion. This provides users with a firmer sofa experience, solving the problem that sofas are not easy to adjust to user preferences. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Reference Figure 1-5 A vibration-damping sofa includes a base 1, with two sets of armrests 2 fixedly connected to both sides of the base 1, and a backrest 3 fixedly connected to one side of the base 1. A round rod 10 is rotatably connected to one side of the inner wall of the base 1, passing through the base 1 and the armrests 2. A first bevel gear 11 is fixedly connected to one end of the round rod 10, and a second bevel gear 12 meshes with the bottom of the first bevel gear 11. A second gear 13 is fixedly connected to the bottom of the second bevel gear 12, and the second gear 13 is rotatably connected to the bottom of the inner wall of the base 1. A first gear 5 meshes with one side of the second gear 13. The inner wall of the base 1 has a threaded hole. A first threaded rod 4 is fixedly connected to the center of the inner wall of the base 1. The first gear 5 is threadedly connected to the outer wall of the first threaded rod 4 through the threaded hole. A mounting plate 6 is fixedly connected to the inner wall of the base 1. A spring 7 is fixedly connected to the top of the mounting plate 6. A top plate 8 is fixedly connected to the top of the spring 7. A cushion 14 is fixedly connected to the top of the top plate 8. A second threaded rod 9 is fixedly connected to the center of the bottom of the top plate 8. The second threaded rod 9 is located at the top of the first threaded rod 4. A circular hole is opened at the center of the mounting plate 6. The second threaded rod 9 is located in the circular hole.

[0022] To address the issue of sofas not being easily adjustable in terms of firmness, when a user needs a softer sofa, the user sitting or lying on the top of the seat cushion 14 creates downward pressure. As the seat cushion 14 and top plate 8 move downwards, they compress the springs 7. Since multiple sets of springs 7 are installed, the compression force also generates an upward restoring force, providing a soft user experience. When a firmer sofa is needed, the round rod 10 can be rotated. When the round rod 10 is rotated, it drives the first bevel gear 11 on one side to rotate. The rotation of the first bevel gear 11 drives the second bevel gear 12 meshing at the bottom to rotate. The rotation of the second bevel gear 12 then drives the first bevel gear 12 meshing at the bottom to rotate. When the second gear 13 rotates, it drives the first gear 5 to rotate. When the first gear 5 rotates, its inner wall is threaded to the outer wall of the first threaded rod 4 through a threaded groove. Therefore, the first gear 5 will gradually move upwards towards the first threaded rod 4. Since the second threaded rod 9 is located at the top of the first threaded rod 4, the top of the threaded groove of the first gear 5 can be gradually slid into the bottom of the second threaded rod 9. At this time, the top and bottom of the first gear 5 are respectively connected to the second threaded rod 9 and the first threaded rod 4, thereby fixing the position of the second threaded rod 9. After the position of the second threaded rod 9 is fixed, the positions of the top plate 8 and the seat cushion 14 can be fixed at the same time, thus providing the user with the experience of a hard sofa.

[0023] Reference Figure 1 The top of the armrest 2 is fixed with a side pad 15. There are two sets of side pads 15, which are symmetrically distributed on the top of the two sets of armrests 2. A backrest 16 is fixed to one side of the backrest 3. Both the side pad 15 and the backrest 16 are filled with cotton.

[0024] By setting a side pad 15 at the top of the armrest 2, a comfortable experience can be provided for the user's armpit, and by setting a backrest 16, a comfortable experience can be provided for the user's back.

[0025] Reference Figure 4 A rotating block 17 is fixedly connected to one end of the round rod 10 away from the first bevel gear 11. The rotating block 17 is located on one side of the handrail 2, and multiple anti-slip grooves are formed on the outer wall of the rotating block 17.

[0026] By setting a rotating block 17 on one side of the round rod 10, the user can easily rotate the round rod 10 by rotating the rotating block 17 when it is necessary to rotate the round rod 10. By setting multiple anti-slip grooves on the outer wall of the rotating block 17, the outer wall of the rotating block 17 can be provided with an anti-slip effect.

[0027] Reference Figure 1The base 1 has a support leg 18 fixedly connected to its bottom. The outer wall of the support leg 18 is covered with a rubber sleeve. There are four sets of support legs 18, which are symmetrically distributed at the bottom of the base 1.

[0028] By setting four sets of support legs 18 at the bottom of the base 1, stable support can be provided for the bottom of the base 1, while the four sets of rubber sleeves on the outer wall of the support legs 18 can provide a cushioning effect for the bottom of the base 1.

[0029] Reference Figure 5 An L-shaped plate 19 is fixed to the inner wall of the base 1. The L-shaped plate 19 is sleeved on the corner of the top plate 8. There are four sets of L-shaped plates 19, which are symmetrically distributed on the inner wall of the base 1.

[0030] By setting four sets of L-shaped plates 19 on the inner wall of the base 1, when the seat cushion 14 and the top plate 8 move up and down, the four sets of L-shaped plates 19 can provide a limit for the movement trajectory of the seat cushion 14 and the top plate 8, and prevent the top plate 8 and the seat cushion 14 from deviating when they move.

[0031] Working Principle: To address the issue of sofas being inconvenient to adjust firmness according to user preferences, when a softer sofa is desired, the user's position on the top of the seat cushion 14 creates downward pressure. As the seat cushion 14 and top plate 8 move downwards, they compress the springs 7. Since multiple sets of springs 7 are present, the compression force generates an upward restoring force, providing a soft user experience. When the seat cushion 14 and top plate 8 move up and down, four sets of L-shaped plates 19 limit their movement, preventing deviation. For a firmer sofa, the rotating block 17 is rotated, causing the round rod 10 to rotate. The round rod 10 then rotates the first bevel gear 11, which in turn rotates the second bevel gear 12 at the bottom. The second bevel gear 12 then rotates the second gear 13 at the bottom. When 13 rotates, it will drive the first gear 5 to rotate. When the first gear 5 rotates, since the inner wall of the first gear 5 is threaded to the outer wall of the first threaded rod 4 through the threaded groove, the first gear 5 will gradually move upward to the first threaded rod 4. Since the second threaded rod 9 is set at the top of the first threaded rod 4, the top of the threaded groove of the first gear 5 can gradually slide into the bottom of the second threaded rod 9. At this time, the top and bottom of the first gear 5 are respectively connected to the second threaded rod 9 and the first threaded rod 4, thereby fixing the position of the second threaded rod 9. After the position of the second threaded rod 9 is fixed, the positions of the top plate 8 and the seat cushion 14 can be fixed at the same time, thereby providing the user with the experience of a hard sofa. By setting the side cushions 15 and the back cushions 16, a comfortable experience can be provided for the user's arms and back. By setting four sets of support legs 18 at the bottom of the base 1, a stable support can be provided for the bottom of the base 1, and the four sets of rubber sleeves set on the outer wall of the support legs 18 can provide a cushioning effect for the bottom of the base 1.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
