Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically a highly reliable modular sofa. Background Technology

[0002] As an indispensable piece of furniture in modern home life, the comfort, aesthetics and durability of sofas have always been the focus of consumers. Traditional sofa designs often emphasize the overall shape and material selection to meet the user's sitting and lying needs.

[0003] In existing designs, the modular structure allows sofas to be freely combined according to actual needs, thereby meeting users' diverse needs for space utilization. This design not only improves the flexibility of sofas but also makes home layout more convenient and personalized.

[0004] Because of the independence between the individual sofa panels, users often tend to sit in a specific area, which reduces the elasticity of the springs inside that area, causing the sofa surface to dent and affecting the visual appeal and user experience.

[0005] The dent problem that occurs when using a high-reliability modular sofa can be solved in two main ways: one is to disassemble the sofa and replace the internal springs. Although this method can solve the problem, it is complicated and costly. The other is to directly replace the individual sofa units. However, sofas produced in different batches are prone to color differences, which can affect the overall aesthetics of the home.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] The purpose of this invention is to provide a highly reliable modular sofa to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a high-reliability modular sofa, including a support plate, wherein an elastic adjustment mechanism is fixedly installed on the inner side wall of the support plate;

[0009] The elastic adjustment mechanism includes a fixed plate fixedly installed on the inner side wall of the support plate. A reciprocating plate is slidably installed on the inner wall of the fixed plate. A locking block is fixedly installed on the side wall of the reciprocating plate. A gear plate is engaged with the outer wall of the locking block. A spiral strip is fixedly installed on the side wall of the gear plate. A toothed column is engaged with the outer wall of the spiral strip. A lifting plate is fixedly installed on the top of the toothed column. Another elastic adjustment mechanism is fixedly installed on the outer wall of the end of the connecting rod away from the telescopic rod. A lifting plate is fixedly installed on the top of both elastic adjustment mechanisms. Multiple springs are fixedly connected to the top of the lifting plate. A fixed frame is fixedly connected to the top of the springs.

[0010] Furthermore, a turntable is rotatably mounted on the side of the reciprocating plate away from the locking block. A connecting rod is fixedly mounted on the inner wall of the turntable. A telescopic rod is fixedly mounted on the end of the connecting rod. A connecting plate is rotatably mounted on the outer wall of the telescopic rod. A rotating handle is rotatably mounted on the bottom end of the inner wall of the connecting plate. A slot is opened on the side wall of the support plate. The inner wall of the slot is equal in size to the outer wall of the connecting plate.

[0011] Furthermore, a sliding plate is fixedly installed at the bottom of the fixed frame, and the bottom of the sliding plate is fixedly connected to the top of the support plate.

[0012] Furthermore, a flexible fabric is fixedly connected to the inner wall of the fixed frame, and a covering sleeve is fitted onto the outer wall of the fixed frame.

[0013] Furthermore, a support leg is fixedly installed at the bottom of the outer wall of the support plate, a backrest is fixedly installed at the top of the outer wall of the support plate, a cushion is pasted on the side wall of the backrest, and a sliding groove is opened on the surface of the lifting plate, with the inner wall of the sliding groove slidably connected to the outer wall of the sliding plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by rotating the toothed disc to drive the toothed column to rise, the elasticity of the sofa springs can be adjusted, which improves the comfort and support of the sofa, and also effectively extends the service life of the sofa. It avoids the problem of reduced spring elasticity and surface depression of traditional sofas due to long-term use. There is no need to disassemble the sofa to replace the springs or replace the entire sofa, which saves maintenance costs and maintains the aesthetics of the home. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a high-reliability modular sofa, including a spring adjustment mechanism fixedly installed on the inner side wall of the support plate 1. The spring adjustment mechanism includes a fixed plate 6 fixedly installed on the inner side wall of the support plate 1, a reciprocating plate 9 slidably installed on the inner wall of the fixed plate 6, a locking block 17 fixedly installed on the side wall of the reciprocating plate 9, and the outer wall of the locking block 17 engaging with the toothed disc 10. Through the sliding of the reciprocating plate 9 on the inner wall of the fixed plate 6 and the engagement of the locking block 17 with the toothed disc 10, the user can adjust the spring of the sofa according to actual needs.

[0023] It should be noted that there are two locking blocks 17, which ensure that they are always engaged with the gear plate 10, preventing the spring 14 from accidentally pushing the lifting plate 13 back to its original position. The side wall of the gear plate 10 is fixedly installed with a spiral strip 18, the outer wall of the spiral strip 18 is engaged with the gear column 11, and the top of the gear column 11 is fixedly installed with the lifting plate 13. The upward movement of the lifting plate 13 is achieved by the lifting of the gear column 11.

[0024] Please see Figure 5 This utility model provides a technical solution: a highly reliable modular sofa, including a handle 21 installed at the bottom of the inner wall of the connecting plate 20. The handle 21 can directly pull the connecting plate 20 to drive the telescopic rod 7 to extend and retract. A connecting rod 12 is fixedly installed at the end of the telescopic rod 7, and the connecting rod 12 is fixedly connected to the inner wall of the turntable 8. The turntable 8 is installed on the side of the reciprocating plate 9 away from the locking block 17. With the rotation of the handle 21, the turntable 8 drives the reciprocating plate 9 to slide smoothly on the inner wall of the fixed plate 6 through the transmission of the connecting rod 12, ensuring that the user can flexibly adjust the elasticity of the sofa by simply rotating the handle 21.

[0025] Please see Figure 2This utility model provides a technical solution: a highly reliable modular sofa, which includes a second elastic adjustment mechanism fixedly installed at the end of the connecting rod 12 away from the telescopic rod 7, realizing the coordinated operation of the two mechanisms, enhancing the stability and reliability of the entire elastic adjustment system, and also connecting the tops of both elastic adjustment mechanisms to the lifting plate 13, thereby fixing multiple springs 14 to the top of the lifting plate 13, and connecting the tops of the springs 14 to the fixed frame 15, optimizing the flexibility of elastic adjustment, and providing a wider elastic adjustment range to meet the diverse needs of different users for sofa elasticity.

[0026] Please see Figure 3 , Figure 4 This utility model provides a technical solution: a highly reliable modular sofa, including a sliding plate 16 as a connector between the fixed frame 15 and the support plate 1. Its bottom is fixedly connected to the top of the support plate 1, while its top is installed at the bottom of the fixed frame 15, ensuring the stability between the entire elastic adjustment mechanism and the sofa frame, preventing possible shaking or instability during use, and providing solid support for the sofa.

[0027] Please see Figure 2 , Figure 4 This utility model provides a technical solution: a highly reliable modular sofa, including a lifting plate 13 with a groove 19 on its surface, the inner wall of which is slidably connected to the outer wall of the sliding plate 16, ensuring that the lifting plate 13 can move along a predetermined trajectory without deviation during the adjustment process, thereby improving the stability and adjustment accuracy of the entire mechanism.

[0028] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a highly reliable modular sofa, including a flexible fabric fixedly connected to the inner wall of a fixed frame 15, and a covering sleeve 2 fitted on the outer wall. The flexible fabric and the covering sleeve 2 together protect the fixed frame 15 and the spring 14, effectively preventing dust, dirt and other impurities from entering the interior of the fixed frame 15, thereby extending the service life of the spring 14 and ensuring the long-term durability of the sofa.

[0029] Please see Figure 5 This utility model provides a technical solution: a highly reliable modular sofa, including a slot 22 opened on the side wall of the support plate 1. The inner wall size of the slot 22 is equal to the outer wall size of the connecting plate 20, which prevents possible shaking or displacement during use and ensures the stability and reliability of the entire structure.

[0030] Please see Figure 1This utility model provides a technical solution: a highly reliable modular sofa, including a support plate 1 with legs 5 fixedly installed at the bottom of the outer wall to provide a solid support foundation for the sofa, ensuring the stability of the sofa during placement and use; a backrest 3 fixedly installed at the top of the outer wall of the support plate 1 to support the user's back, reducing fatigue that may be caused by prolonged sitting; and a cushion 4 pasted on the side wall of the backrest 3 to provide the user with soft and comfortable back support.

[0031] Furthermore, multiple support panels 1 can be placed together to form a sofa set, giving the sofa a high degree of flexibility in layout and combination. This allows users to freely choose different numbers of support panels 1 to combine sofas of different sizes and shapes according to their needs and preferences, thereby meeting different usage scenarios and space requirements.

[0032] Working Principle: When the sofa is in normal use, the various components inside the elastic adjustment mechanism remain in relatively fixed positions. Spring 14 provides basic elasticity within the fixed frame 15, ensuring the comfort and support of the sofa cushion. As the sofa is used over time, the spring 14 inside gradually loses its elasticity, resulting in insufficient support for the sofa cushion. At this time, the user needs to adjust the elasticity by unhooking the handle 21 on the connecting plate 20 and then pulling the connecting plate 20 outward, causing the telescopic rod 7 to extend. At this time, the connecting plate 20 leaves the slot 22 on the side wall of the support plate 1. With the telescopic rod 7 as the axis, first rotate the handle 21 clockwise half a turn, then rotate it counterclockwise half a turn, repeating this operation. The rotation of the telescopic rod 7 drives the connecting rod 12 to rotate, which in turn drives the turntable 8 to rotate back and forth. The back and forth rotation of the turntable 8 then drives the reciprocating plate 9 to rotate on the left side of the inner wall of the fixed plate 6. Moving to the right, the locking block 17 on the side wall of the reciprocating plate 9 engages with the tooth peaks on the surface of the gear plate 10. As the reciprocating plate 9 moves left and right, the locking block 17 drives the gear plate 10 to rotate clockwise. The spiral strip 18 on the side wall of the gear plate 10 rotates with the rotation of the gear plate 10. The rotation of the spiral strip 18 causes the tooth column 11 that it meshes with to rise. The rise of the tooth column 11 lifts the lifting plate 13, thereby simultaneously adjusting the elasticity of multiple springs 14. Users can adjust the elasticity of the springs 14 according to their own needs by adjusting the height of the lifting plate 13. After adjusting to the user's satisfactory elasticity, the user aligns the connecting plate 20 with the slot 22 and then presses it into the slot 22. Then, the rotating handle 21 is retracted into the connecting plate 20. At this time, the entire device is locked, and the elasticity of the springs 14 remains stable, ensuring that the sofa always maintains good support and comfort, and extending the service life of the sofa.
