Description

Technical Field

[0001] The present application relates to the field of massage sofas. Specifically, it relates to a sofa frame for a massage sofa that is convenient for adjusting the height. Background Art

[0002] At present, a massage sofa is a multi-seat chair with cushions, a backrest chair equipped with springs or thick foam plastics, and armrests on both sides. It is a kind of soft furniture.

[0003] Publication (Announcement) No. CN221105333U discloses a multifunctional massage sofa, including a sofa body that is detachably arranged; a first massage part is telescopically arranged on the sofa body; a second massage part is arranged below the first massage part and can reciprocate back and forth; a third massage part is arranged on the seat cushion of the sofa body; a fourth massage part that can approach and pound each other is arranged between the adjacent second massage part and the third massage part; wherein: during work, the driving part on the sofa body drives the second massage part to descend and drives the third massage part to ascend, so that the whole sofa is in a reclined state for massage. The utility model has the advantage of convenient use, and solves the problems that the existing sofa only has the function of allowing people to lean on, does not have the massage function, and is not convenient to move, resulting in a single function and unable to meet the use requirements;

[0004] The above-mentioned existing technical solutions have the following defects: the height of the depression of the cushion is fixed and cannot be adjusted. During use, it cannot be adjusted according to the use requirements. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the present application provides a sofa frame for a massage sofa that is convenient for adjusting the height, aiming to improve the problem that the height of the depression of the cushion is fixed and cannot be adjusted.

[0006] The embodiment of the present application provides a sofa frame for a massage sofa that is convenient for adjusting the height, including a massage sofa frame and a cushion height adjustment component; the massage sofa frame includes a base and a seat cushion, and a column is fixed between the bottom of the seat cushion and the base;

[0007] The cushion height adjustment component includes a support plate and a limit rod. The support plate is slidably connected to the column. A side plate is fixed to the end of the support plate. A profiling plate is fixed to the upper end of the side plate. The profiling plate is arranged directly below the seat cushion. The limit rod is slidably connected to the side plate. The lower end of the column is fixed to the base. A limit hole is opened on the side wall of the column. A plurality of the limit holes are arranged at equal intervals along the length direction of the column. One end of the limit rod is cooperatively inserted into the limit hole.

[0008] In a preferred embodiment of the present utility model, a backrest is installed on one side of the seat cushion, an elastic load-bearing net is woven on the surface of the seat cushion, and the upper surface of the profiling plate is recessed to be contoured according to ergonomics.

[0009] One side of the seat cushion is closely connected with a backrest, providing stable support for the user. The surface of the seat cushion is carefully woven with an elastic load-bearing net, which not only provides excellent buffering performance but also can deform according to the user's body shape and weight to ensure comfort during long-term use. The seat cushion is supported by a profiling plate below. The upper surface of the profiling plate is concave, and the height and shape of the concavity are contoured according to ergonomics, aiming to provide the user with an extremely fitting feeling and support force, thus greatly improving the user experience.

[0010] In a preferred embodiment of the present utility model, a sliding sleeve is fixed at the center position of the support plate, the sliding sleeve is sleeved on the surface of the column, side plates are respectively arranged at both ends of the support plate, and the profiling plate is fixed at the upper ends of the two side plates.

[0011] The support plate is closely sleeved on the outer surface of the column through the fixed sliding sleeve at its center position, ensuring the stability of the support plate sliding in the vertical direction. Side plates are respectively arranged at both ends of the support plate, and the upper ends of the side plates are further fixed to the profiling plate. Such a design not only enhances the strength and integrity of the structure but also enables the entire device to better adapt to workpieces of different shapes, improving the processing efficiency.

[0012] In a preferred embodiment of the present utility model, a communication groove is arranged between adjacent limiting holes, a support rod is fixed at one end of the limiting rod, the diameter of the support rod is smaller than the outer diameter of the limiting rod, and the support rod can slide through the communication groove.

[0013] A communication groove is arranged between adjacent limiting holes, providing a channel for the sliding of the support rod. The diameter of the support rod is smaller than the outer diameter of the limiting rod, so that it can slide stably between the limiting holes. The diameter design of the support rod also ensures that it cannot pass through the communication groove when it is clamped with the limiting hole. The sliding of the support rod through the communication groove provides flexibility for the displacement of the limiting rod, enabling the overall structure to be adjusted as needed and enhancing the stability and reliability of the structure.

[0014] In a preferred embodiment of the present utility model, one end of the limiting rod slides through a through hole opened on the surface of any one of the side plates, and one end of the support rod slides through the surface of the corresponding side plate at the corresponding position.

[0015] One end of the limiting rod slides in any one of the side plates. At the same time, one end of the support rod also slides in the corresponding side plate through the through hole opened on its surface, cooperating with the limiting rod to achieve axial sliding and ensuring the stability of the structure.

[0016] In a preferred embodiment of the present utility model, a pull ring is fixed at one end of the limiting rod, the pull ring is arranged on the outer surface of the side plate, and a first compression spring is connected between the limiting rod and any one of the side plates.

[0017] The pull ring is arranged on the outer surface of the side plate. It can provide a certain reverse force during mechanical movement. After the external force is removed, it can push the limiting rod to slide back to its original position, so that the movement of the limiting rod is inserted into the limiting hole.

[0018] In a preferred embodiment of the present utility model, a second compression spring is arranged between the support plate and the base, and the second compression spring is sleeved on the surface of the upright post.

[0019] The support plate is arranged above the base, and the two are elastically connected through the second compression spring. This design not only enables the support plate to be adjusted in height according to actual needs, but also ensures the stability of the device during use. The second compression spring is sleeved on the surface of the upright post, providing an additional upward thrust for the support plate, effectively performing elevation adjustment. When lowering, by pressing down the support plate, it is convenient to adjust the height of the seat cushion of the sofa frame and improves the comfort of use.

[0020] Beneficial effects: The present application provides a sofa frame for a massage sofa that is convenient for height adjustment. The profiling plate is fixedly installed directly below the seat cushion to simulate the human curve and provide a conforming support. The limiting rod is connected to the side plate to ensure that its position is flexibly adjustable. The lower end of the upright post is firmly fixed to the base, providing a stable support for the entire device. A plurality of limiting holes are formed in the side wall of the upright post, and these limiting holes are arranged at equal intervals along the length direction of the upright post, so that the limiting rod can be inserted into these limiting holes as needed to adjust the height of the profiling plate, realizing the adjustment of the depression height of the seat cushion. The depression height of the soft cushion can be adjusted, and during use, it can be adjusted according to the use requirements for personalized adaptation and improved use experience.
