DETAILED DESCRIPTION

[0018] The technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application provides a sofa with a reinforced support combination spring, comprising a sofa seat 1 and a backrest 2, a cushion 4 and two armrests 3 detachably fixedly connected to the top of the sofa seat 1, wherein:

[0020] The sofa seat 1 includes a base 5, multiple cushions 6, a Chinese-shaped support frame 7, a combined spring mechanism 1 8, multiple combined spring mechanisms 2 9 and a fabric cloth 10. The multiple cushions 6 are fixedly installed at the bottom of the base 5 and are symmetrically distributed in pairs. The base 5 can be raised to a certain height from the ground by using multiple cushions 6. The Chinese-shaped support frame 7 is fixedly installed on the top of the base 5. The combined spring mechanism 1 8 is arranged on the top of the Chinese-shaped support frame 7. The Chinese-shaped support frame 7 is used to carry and support the combined spring mechanism 1 8. The combined spring mechanism 1 8 is used to support the cushion 4 and the person sitting on the cushion 4. The multiple combined spring mechanisms 2 9 are arranged on the base 5 and The combination spring mechanism 1 8 is arranged between the combination spring mechanisms 2 and 9, and the multiple combination spring mechanisms 2 9 are all located in the U-shaped support frame 7. The multiple combination spring mechanisms 2 9 can provide a stable supporting force to the combination spring mechanism 8, improve the bearing strength of the combination spring mechanism 8, make the combination spring mechanism 8 rebound smoothly and not easily deformed, increase the force range of the combination spring mechanism 8, and thus more stably support the person sitting on the cushion 4. In addition, the multiple combination spring mechanisms 2 9 also have a good shock-absorbing effect, which improves the comfort of people sitting on the sofa. The fabric cloth 10 is wrapped around the outer surface of the base 5, the U-shaped support frame 7 and the combination spring mechanism 8.

[0021] In this embodiment, the above-mentioned combined spring mechanism 8 includes a plurality of serpentine tension springs 81, and the plurality of serpentine tension springs 81 are evenly spaced and distributed on the top of the U-shaped support frame 7. The two ends of the serpentine tension spring 81 are respectively fixedly connected to the two sides of the top of the U-shaped support frame 7. By utilizing the elastic deformable properties of the plurality of serpentine tension springs 81 themselves, people sitting on the sofa can be made more comfortable.

[0022] In this embodiment, the above-mentioned combined spring mechanism 2 9 includes an upper connecting plate 91, a lower connecting plate 92, a first spring 93, a second spring 94 and a telescopic rod 95. The upper connecting plate 91 is fixedly connected to the bottom of the serpentine tension spring 81, and the lower connecting plate 92 is fixedly connected to the top of the base 5. The two ends of the first spring 93 are respectively fixedly connected to the side where the upper connecting plate 91 and the lower connecting plate 92 are close to each other, and the two ends of the second spring 94 are respectively fixedly connected to the side where the upper connecting plate 91 and the lower connecting plate 92 are close to each other, and the first spring 93 is located in the second spring 94, and the spiral directions of the first spring 93 and the second spring 94 are oppositely arranged, and the telescopic rod 95 is arranged to be telescopic. The rod 95 is arranged between the upper connecting plate 91 and the lower connecting plate 92, and the first spring 93 is sleeved on the telescopic rod 95. The telescopic rod 95 can be used to guide the movement direction of the upper connecting plate 91, so that the upper connecting plate 91 can maintain vertical movement when subjected to force, thereby making it difficult for the first spring 93 and the second spring 94 to be twisted when subjected to force and compressing, thereby extending the service life of the first spring 93 and the second spring 94. By utilizing the joint cooperation of the first spring 93 and the second spring 94 with opposite spiral directions, the stability of the support of the combined spring mechanism 8 can be improved, the load-bearing strength can be enhanced, and a good shock-absorbing effect can be achieved.

[0023] In this embodiment, a plurality of elastic metal rods 11 are fixedly connected to the bottom of the plurality of serpentine tension springs 81. The plurality of elastic metal rods 11 are distributed at equal intervals and are used to enhance the stability of the plurality of serpentine tension springs 81 and improve the elastic force of the combined spring mechanism 8. It should be noted that the elastic metal rods 11 are made of spring steel.

[0024] In this embodiment, the telescopic rod 95 includes a hollow sleeve and a sliding rod. The bottom end of the hollow sleeve is fixedly connected to the top of the lower connecting plate 92, and the bottom end of the sliding rod is slidably installed in the hollow sleeve. The top end of the sliding rod is fixedly connected to the bottom of the upper connecting plate 91. The sliding connection of the sliding rod in the hollow sleeve can guide the movement direction of the upper connecting plate 91, so that the upper connecting plate 91 can move in the vertical direction.

[0025] Through the above structure, when the sofa with enhanced support combination spring provided by the present application is in use, when people sit on the sofa, a downward force will be applied to the multiple serpentine tension springs 81, and the multiple serpentine tension springs 81 will be deformed by the force, so that the parts where the multiple serpentine tension springs 81 are stressed are concave. By utilizing the combination spring mechanism 29 composed of the upper connecting plate 91, the lower connecting plate 92, the first spring 93, the second spring 94 and the telescopic rod 95, under the joint cooperation of the multiple combination spring mechanisms 29, a stable supporting force can be provided to the multiple serpentine tension springs 81, the bearing strength of the multiple serpentine tension springs 81 can be enhanced, and the force range of the multiple serpentine tension springs 81 can be increased, so that people sitting on the seat cushion 4 can be supported more stably, and the comfort of people sitting on the sofa can be improved. When people leave the sofa, the combination spring mechanism 18 can rebound smoothly and is not easy to deform. In addition, by utilizing the joint cooperation of the first spring 93 and the second spring 94 with opposite spiral directions, it also has a good shock absorption effect, further improving the comfort of people sitting on the sofa.
