[0010] The cover is fixedly connected to the end of the support rod, and the space between the cover and the sofa is filled with gas.

[0011] Wherein, the locking part includes a partition, which is fixedly connected to the inside of the accommodating cavity, a hole is opened on the outer surface of the upper end of the partition, a plug is provided at a position corresponding to the hole inside the accommodating cavity, and a push rod is fixedly connected to the upper end of the plug.

[0012] Among them, a sliding block with an L-shaped structure design is fixedly connected to the annular outer surface of the push rod, and a sliding groove is provided at a position corresponding to the sliding block on the inner surface of the accommodating cavity.

[0013] A slot is provided on the inner surface of the opening of the accommodating cavity, and a plug plate with an L-shaped structure is slidably connected inside the slot.

[0014] The utility model has at least the following beneficial effects:

[0015] By providing the support part, when the user's waist leans against the outer surface of the skin, the support rod will naturally slide along the telescopic groove to fit the curvature of the user's waist, and then the overall telescopic amount of the support rod will be limited by the locking part, so that the user's waist is always supported by the support rod when sitting on the sofa. Compared with traditional support plates with curvature, it has higher flexibility and also has adaptive capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0023] See also Figure 1-5, the utility model provides a technical solution: a lumbar support structure of a sofa seat, comprising a sofa 1;

[0024] The support part 2 is located on the outer surface of the sofa 1 close to the inner side, and can quickly imprint the curvature of the user's waist. The locking part 3 arranged at the top of the sofa 1 limits the extension and contraction amount of the support part 2, thereby meeting the curvature of the waist of different users and meeting the needs of more users for waist support.

[0025] The support portion 2 includes a skin 20, and the skin 20 is more connected to the inner outer surface of the sofa 1. The inner outer surface of the sofa 1 is provided with a plurality of telescopic grooves 21, and the telescopic grooves 21 are telescopically connected with support rods 22. When a user leans on the inner surface of the sofa 1, the user's waist will contact the skin 20 and squeeze the support rod 22, so that it can be telescoped inside the telescopic groove 21, and the curvature of the user's waist is imprinted. The locking portion 3 is used to limit the overall telescopic amount of the support rod 22. After the support rod 22 reaches the maximum telescopic amount, the user's waist can be effectively supported. No matter which part of the support rod 22 the user contacts, as long as the overall telescopic amount of the support rod 22 reaches the maximum, the user's waist can be effectively supported.

[0026] An accommodating chamber 32 is provided at one end of the telescopic slot 21 away from the support rod 22, and an elastic rope 23 is fixedly connected to the corresponding position of the support rod 22 inside the accommodating chamber 32. Liquid water is injected into the accommodating chamber 32. When the support rod 22 moves along the telescopic slot 21 into the accommodating chamber 32, the water inside the telescopic slot 21 and the accommodating chamber 32 will be compressed. The elastic rope 23 will increase the fit between the support rod 22 and the liquid water, thereby increasing the stability of the support rod 22.

[0027] The cover 20 is fixedly connected to the end of the support rod 22 , and gas is filled between the cover 20 and the sofa 1 . The cover 20 itself is elastic, and the connection with the support rod 22 facilitates the subsequent resetting of the support rod 22 .

[0028] The locking portion 3 includes a partition 37, which is fixedly connected to the inside of the accommodating cavity 32. A hole 38 is provided on the outer surface of the upper end of the partition 37. A plug 36 is provided at a position corresponding to the hole 38 in the accommodating cavity 32. A push rod 34 is fixedly connected to the upper end of the plug 36. When the support rod 22 moves inside the telescopic groove 21, liquid water is squeezed and overflows from the hole 38 and impacts the plug 36. The excess liquid water is separated by the partition 37.

[0029] The annular outer surface of the push rod 34 is fixedly connected with a slider 35 of L-shaped structure design, and the inner surface of the accommodating cavity 32 is provided with a slide groove 33 at a position corresponding to the slider 35. The push rod 34 moves up and down along the slide groove 33 through the slider 35 to guide the plug 36 and the push rod 34.

[0030] A slot 30 is provided on the inner surface of the opening of the accommodating cavity 32, and an insert plate 31 with an L-shaped structure is slidably connected inside the slot 30. When the user pulls the insert plate 31 out of the slot 30 to seal the opening of the accommodating cavity 32, the push rod 34 will be resisted by the insert plate 31. At this time, the plug 36 is completely blocked in the hole 38. At this time, the entire support rod 22 is supported by the water pressure, and the overall expansion and contraction amount becomes a fixed expansion and contraction amount. The elastic rope 23 will increase the pressure between the support rod 22 and the liquid water.

[0031] Directions:

[0032] The user first inserts the plug plate 31 into the slot 30 to expose the opening of the accommodating chamber 32, and then leans against the surface of the sofa 1. The support rod 22 expands and contracts inside the expansion slot 21, squeezing excess liquid water through the hole 38 to the top of the partition 37. Then the user closes the opening of the accommodating chamber 32 again with the plug plate 31. At this time, the plug plate 31 resists the push rod 34, and the hole 38 is completely blocked to limit the overall expansion and contraction of the support rod 22. Through the mutual cooperation of the above structures, the support effect on the user's waist can be increased, making the ride more comfortable.
