[0027] like Figure 1-9 As shown, a sofa chair that is easy to disassemble and clean includes a base plate 1, a support seat 2, an armrest structure 4, and a fastening mechanism 3. The support seat 2 is fixed to the upper end of the base plate 1. The armrest structure 4 is U-shaped and is vertically inserted into the base plate 1 and attached to the outer wall of the support seat 2. The fastening mechanism 3 is used to fix the support seat 2 and the armrest structure 4.

[0028] As shown in 2, 3, 5, 7, and 9, the latching mechanism 3 includes a rack 301, a spring 305, and insert plates 311. The rack 301 slides into the support base 2 from the front end of the support base 2. The spring 305 is located in the rack 301 and drives the rack 301 to move horizontally. The two insert plates 311 are symmetrically arranged on both sides of the rack 301 and are driven by the rack 301 to slide into the inner wall of the support structure 4. The front end of the support base 2 has an adjustment groove 201. The front end of the adjustment groove 201 is fastened with an interference fit connecting cover 203 for closing the adjustment groove 201. The upper end of the adjustment groove 201 is provided with... The groove 202 facilitates the fastening of the connecting cover 203 from the adjusting groove 201. The support base 2 has a first sliding groove 204 horizontally and longitudinally distributed and connected to the adjusting groove 201. The rack 301 slidably engages within the first sliding groove 204, limiting the rack 301 to slide horizontally and longitudinally within it. One end of the rack 301 is fixedly connected to a connecting plate 306 located within the adjusting groove 201. A handle 307 is fixedly connected to the connecting plate 306. A baffle 206 is vertically fixed to the first sliding groove 204. A second sliding groove 303 is provided vertically through and slidably engaged with a baffle 206. A horizontally distributed sliding rod 304 is fixedly connected in the second sliding groove 303. The sliding rod 304 slides through the baffle 206. A spring 305 is sleeved on the sliding rod 304. The two ends of the spring 305 are respectively fixed to the inner wall of the second sliding groove 303 and the baffle 206. A first tooth groove 302 is symmetrically distributed on both sides of the rack 301. A first gear 308 is meshed on both sides of the rack 301 through the first tooth groove 302. A second gear 310 is fixedly connected to the lower end of the first gear 308 through a connecting shaft 309. The insert plate 311 The front end is provided with a second tooth groove 312, and the second gear 310 meshes with the second tooth groove 312. The inner wall of the support structure 4 is provided with slots 401 on the left and right sides. The insert plate 311 is inserted into the slot 401. One end of the insert plate 311 inserted into the slot 401 is set as an inclined surface 313. When the support structure 4 is installed vertically downward on the support base 2, the support structure 4 compresses the inclined surface 313 to cause the insert plate 311 to contract and compress the spring 305. When the support structure 4 abuts against the base plate 1, under the rebound action of the spring 305, the insert plate 311 is inserted into the slot 401, thereby realizing the limiting and fixing of the support structure 4 and the support base 2.

[0029] like Figure 7-8As shown, the first slide groove 204 has symmetrical first mounting grooves 205 on both sides. The two first gears 308 are rotatably mounted in the first mounting grooves 205. The lower vertical end of the first mounting groove 205 has a second mounting groove 207. The connecting shaft 309 extends rotatably from the first mounting groove 205 into the second mounting groove 207. The second gear 310 is rotatably mounted in the second mounting groove 207. The rotation limit of the connecting shaft 309 in the support 2 makes the first gear 308 and the second gear 310 rotate stably in the first mounting groove 205 and the second mounting groove 207, thereby meshing with the insert plate 31. 1. The second mounting groove 207 is provided with a third sliding groove 208 that is horizontally distributed and penetrates the outside of the support base 2 at its rear end. The insert plate 311 is slidably engaged in the third sliding groove 208. The stability of the movement of the insert plate 311 is improved by limiting the third sliding groove 208. Under the action of the spring 305, the insert plate 311 extends out of the third sliding groove 208 in its natural state and is inserted into the slot 401, so that the support structure 4 and the support base 2 are fixedly installed. When disassembly is required, the handle 307 can be pulled to drive the insert plate 311 out of the slot 401, so as to realize the disassembly and separation of the support structure 4 and the support base 2.

[0030] like Figure 2 , 3 As shown, the base plate 1 is provided with a plurality of limiting rods 101, and the lower end of the support structure 4 is provided with a plurality of limiting grooves 402 that are interlocked with the limiting rods 101, thereby improving the stability of the connection between the support structure 4 and the support base 2.

[0031] like Figure 2 , 4 As shown, the upper end of the support base 2 is provided with Velcro 6, and the soft cushion 5 is attached to the support base 2 through Velcro 6.

[0032] When using and installing this utility model, the support structure 4 is vertically lowered along the support base 2. The inner wall of the support structure 4 is pressed against the inclined surface 313 of the insert plate 311 at both ends of the support base 2, causing the insert plate 311 to retract into the third sliding groove 208. At this time, the spring 305 retracts until the limiting rod 101 is inserted into the limiting groove 402 of the support structure 4. Under the rebound of the spring 305, the insert plate 311 is inserted into the slot 401, thus realizing the installation of the support structure 4 and the support base 2.

[0033] When disassembly is required, the connecting cover 203 is snapped off from the regulating groove 201 via the groove 202. Pulling the handle 307 moves the connecting plate 306, which in turn causes the rack 301 to slide outward in the first sliding groove 204. This causes the second sliding groove 303 on the rack 301 to slide on the baffle 206, compressing the spring 305. The rack 301 engages with the first tooth grooves 302 on both sides, causing the first gear 308 to rotate in the first mounting groove 205. This, in turn, drives the second gear 310 to rotate in the second mounting groove 207 via the connecting shaft 309. The second tooth groove 312 engages with the second tooth groove 312 at the front end of the insert plate 311, causing the insert plate 311 to slide inward in the third sliding groove 208. That is, the two insert plates 311 slide inward toward each other, causing the insert plate 311 to disengage from the slot 401 in the support structure 4. At this point, the support structure 4 can be pulled upward to disassemble, making it easier to clean.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
