The seat plate connection component 1 includes a seat plate frame 101, a support plate 102, a bottom connection plate 103, a clamping block 104, a connecting seat plate 105, and a first card slot 106, which facilitates the connection and installation of the seat plate frame 101 and the connecting seat plate 105. The installation method is simple and convenient. The seat plate frame 101, the support plate 102, and the bottom connection plate 103 form a right triangle with the seat plate frame 101 and the bottom connection plate 103 as the right-angled sides, and the seat plate frame 101 forms a snap-fitting structure with the connecting seat plate 105 through the clamping block 104 and the first card slot 106. By sliding the clamping block 104 into the first card slot 106, the seat plate frame 101 and the connecting seat plate 105 can be connected and installed. The installation method is simple and convenient, and the operation is simple. In addition, a support plate 102 is inclined inside the seat plate frame 101, so that a triangle is formed among the seat plate frame 101, the support plate 102, and the bottom connection plate 103. Since a triangle has stability, the device can be made more stable and reliable during use. On the other hand, welding is performed using the P-shaped pipe 2, making the welded interface more stable and increasing the practicality of the device.

[0027] Please refer to Figure 1 and Figure 4 As shown in the figure, a combined sofa connection component, the backrest armrest connection component 3, includes a backrest frame 301, a second card slot 302, a clamping block 303, an armrest frame 304, and a third card slot 305, which can achieve the rapid installation among the connecting seat plate 105, the backrest frame 301, and the armrest frame 304. The operation is simple. The backrest frame 301 forms a snap-fitting structure with the seat plate connection component 1 through the second card slot 302, the backrest frame 301 forms a snap-fitting structure with the armrest frame 304 through the clamping block 303, and the armrest frame 304 forms a snap-fitting structure with the seat plate connection component 1 through the third card slot 305.

At the same time, the armrest frame 304 is connected and fixed to the connecting seat plate 105 through the third card slot 305. At this time, the backrest frame 301 and the armrest frame 304 can be connected through the clamping block 303, and at this time, the backrest frame 301 and the armrest frame 304 will be fixed together, so as to achieve the rapid installation among the connecting seat plate 105, the backrest frame 301, and the armrest frame 304. The operation is simple and convenient, and it is easy to use.

[0028] Please refer to Figure 1 and Figure 5As shown in the figure, a combined sofa connection component, a mobile fixing component 4, includes a fixing plate 401, an inclined plate 402, a mobile wheel 403, a threaded rod 404, a control handle 405, and a fixing block 406, which facilitates moving the device through the mobile wheel 403 and fixing the position through the fixing block 406. The fixing block 406 and the mobile wheel 403 form a lifting structure through the threaded rod 404, and the threaded rod 404 and the fixing plate 401 form a lifting structure. Moreover, the fixing plate 401, the inclined plate 402, and the backrest armrest connection component 3 form a right triangle with the fixing plate 401 and the backrest armrest connection component 3 as the right-angled sides. By providing the mobile wheel 403 on the side of the armrest frame 304, the device can be moved to the position where it needs to be used through the mobile wheel 403, and the moving method is convenient. When the device needs to be fixed, the threaded rod 404 can be rotated. At this time, the threaded rod 404 will drive the fixing block 406 to slide downward and press against the ground, thereby supporting and fixing the device.

[0029] Working principle: First, use the P-shaped pipe 2 for support welding, which can make the welding interface more stable and the welding more convenient. Subsequently, slide the block 104 on the side of the seat plate frame 101 into the first card slot 106 opened on the side of the connecting seat plate 105, thereby connecting and fixing the seat plate frame 101 and the connecting seat plate 105. Since the support plate 102 is inclined at the bottom of the seat plate frame 101, a triangle will be formed between the seat plate frame 101, the support plate 102, and the bottom connecting plate 103. Due to the stability of the triangle, the device will be more stable and reliable when in use.

[0030] Next, connect the backrest frame 301 to the connecting seat plate 105 through the second card slot 302, and then connect and fix the armrest frame 304 to the connecting seat plate 105 through the third card slot 305. At this time, the armrest frame 304 will be attached to the side of the backrest frame 301, and then connect and fix the armrest frame 304 and the backrest frame 301 through the engaging block 303. Finally, since the mobile wheel 403 is provided on the side of the armrest frame 304, the device can be moved to the position where it needs to be placed. When the position is determined, the control handle 405 can be rotated at this time. At this time, the control handle 405 will drive the threaded rod 404 to rotate accordingly, and at the same time, the threaded rod 404 will drive the fixing block 406 to slide downward and press against the ground, thereby supporting and fixing the device. In addition, an inclined plate 402 is provided, and the inclined plate 402 will make a triangle between the fixing plate 401, the inclined plate 402, and the armrest frame 304. The stability property can be utilized to make the device more firmly supported and fixed.
