[0030] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] See also Figure 1 and Figure 2 As shown, the utility model designs an anti-collapse sofa, which includes:

[0033] The seat cushion assembly 10 includes a seat cushion body 11 and an intermediate cushion core 15 detachably connected to the seat cushion body 11;

[0034] The sofa frame 20, the cushion body 11 is fixedly mounted on the sofa frame 20, and the sofa frame 20 is provided with an inspection window at a position corresponding to the middle cushion core 15;

[0035] The supporting assembly 30 is detachably mounted at the inspection window and is used to support the cushion assembly 10 upward.

[0036] Specifically, a cavity 14 with an opening facing downward is provided in the middle of the bottom surface of the cushion body 11 , and the middle cushion core 15 is located in the cavity 14 .

[0037] It should be noted that the seat cushion body 11 of the utility model is fixed on the sofa frame 20. When the user sits on the seat cushion body 11, the seat cushion body 11 is not easy to shift. When the middle cushion core 15 is damaged, the connection between the supporting assembly 30 and the sofa frame 20 is cancelled, and the middle cushion core 15 can be separated from the cavity 14. Then, the new middle cushion core 15 is replaced in the cavity 14, and the supporting assembly 30 is connected to the sofa frame 20. It is very simple and the user can repair it by himself without returning to the factory. The maintenance time is greatly shortened and the efficiency is greatly improved.

[0038] Specifically, the cushion body 11 includes a frame pad 12 with a cavity 14 in the middle, and a fabric pad 13 laid on the frame pad 12. The frame pad 12 of the utility model can be integrally formed with the fabric pad 13, or can be connected together by sewing, which is not limited in the utility model.

[0039] Specifically, the sofa frame 20 includes a seating frame 21 with an inspection window, and a backrest frame 22 located at the rear end of the seating frame 21;

[0040] The lower ends of the seat frame 21 and the backrest frame 22 are provided with bottom windows, and a bottom plate 40 is detachably installed at the bottom window;

[0041] The seating frame 21 , the supporting assembly 30 , the backrest frame 22 , and the bottom plate 40 surround and form an inner frame space 23 .

[0042] Specifically, the space 23 within the frame is provided with a spare cushion core 44 having the same shape and size as the middle cushion core 15 .

[0043] When the middle cushion core 15 of the utility model is damaged, it is necessary to cancel the connection between the bottom plate 40 and the sofa frame 20 in order to enter the space 23 in the frame. After entering the space 23 in the frame, cancel the connection between the supporting assembly 30 and the sofa frame 20. The middle cushion core 15 will separate from the cavity 14 under the action of gravity. At this time, place the spare cushion core 44 in the cavity 14, and then connect the supporting assembly 30 to the sofa frame 20, and connect the bottom plate 40 to the sofa frame 20. The user does not need to find an additional middle cushion core 15, which brings great convenience to the user. Of course, it should be noted that the utility model realizes the connection between the bottom plate 40 and the sofa frame 20 and the connection between the supporting assembly 30 and the sofa frame 20 through bolts. In actual applications, users can also choose other methods, and the utility model does not limit this.

[0044] Specifically, in order to prevent the spare cushion core 44 from being damaged or soiled, the anti-collapse sofa further includes an air bubble bag 45 , in which the spare cushion core 44 is housed.

[0045] Specifically, the supporting assembly 30 includes a supporting frame 31 , a spring buckle 33 and a supporting member 32 . The spring buckle 33 is connected to the supporting frame 31 , and the supporting member 32 is detachably connected to the spring buckle 33 .

[0046] Specifically, the supporting member 32 includes one or more of a flat spring, an elastic band or an arch spring.

[0047] The supporting frame 31 of the present invention is an iron frame, which provides a solid framework to ensure the stability of the sofa. The spring buckle is arranged between the iron frame and the cushion body 11. The supporting member 32 corresponds to the spring buckle one by one, providing excellent elasticity and supporting force to ensure the comfort of the sofa. The supporting member 32 is detachably connected to the spring buckle. When any supporting member 32 is damaged, it is only necessary to remove the supporting member 32 for replacement, which is very simple. Of course, it should be noted that the supporting member 32 of the present invention includes one or more of a flat spring, an elastic band or an arch spring. In actual applications, other types of supporting members 32 can also be selected, and the present invention does not limit this.

[0048] Specifically, the anti-collapse sofa further includes a sofa leg 41 , the sofa leg 41 is provided with a threaded rod 42 , the bottom plate 40 is provided with a threaded hole, and the threaded rod 42 is threadedly connected to the bottom plate 40 .

[0049] The sofa legs 41 of the present invention can create a certain space between the base plate 40 and the ground, which is convenient for cleaning. The threaded rod 42 of the sofa legs 41 is threadedly connected to the threaded hole of the base plate 40. The user can adjust the height of the base plate 40 from the ground according to their own needs. Of course, in actual applications, the height of the base plate 40 from the ground can also be adjusted by other methods, and the present invention does not limit this.

[0050] Specifically, the anti-collapse sofa also includes a pillow 43, which is detachably connected to the backrest frame 22. The pillow 43 of the utility model can provide additional back support and enhance the comfort of the sofa. The pillow 43 is detachably connected to the backrest frame 22.
