They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] like Figures 1 to 3 A preferred embodiment of a rotation locking mechanism for a seat assembly is shown. The seat assembly includes a seat 21 and a seat support mechanism 22. The seat 21 is mounted on the seat support mechanism 22 and is rotatable relative to the seat support mechanism 22. The rotation locking mechanism 23 is fitted at the connection between the seat 21 and the seat support mechanism 22. The rotation locking mechanism 23 includes a locking switch lever 231 and a resilient locking component. The locking switch lever 231 drives the resilient locking component to lock and unlock the rotation of the seat 21.

[0033] Specifically, the seat 21 has a tray 211 at its bottom; the seat support mechanism 22 has a support plate 221 at its top, the tray 211 being rotatably connected to the support plate 221, so that the entire seat assembly 2 can rotate relative to the seat support mechanism 22.

[0034] A mounting housing 212 is installed on a tray 211 at the bottom of the seat, and the locking switch 231 is rotatably mounted on the mounting housing 212. Specifically, the locking switch 231 has a lever portion 2311 and a rotating actuating portion 2312. The lever portion 2311 extends out of the mounting housing 212, and the rotating actuating portion 2312 is rotatably connected to the front of the mounting housing 212 via a pivot. The rotating actuating portion 2312 has a shallow notch 2314 and a deep notch 2313 that mate with the elastic locking assembly. A connecting protrusion is formed between the deep notch 2313 and the shallow notch 2314.

[0035] The assembly housing 212 has an assembly sliding cavity, and the elastic locking assembly is assembled in the assembly sliding cavity of the assembly housing 212. The elastic locking assembly includes a slider 232 and a locking block 233. The slider 232 has a moving cavity inside, and the locking block 233 is assembled in the moving cavity, with the locking head 2331 of the locking block 233 extending out of the assembly housing 212. The slider 232 also has a guide groove 2321, and the locking block 233 has a guide shaft 2332 that cooperates with the guide groove 2321. The locking block 233 and the slider 232 can move relative to each other. A return spring 234 is assembled between the side of the slider 232 away from the locking switch and the assembly housing 212, and a cooperating spring 235 is installed between the locking block 233 and the slider 232. The return spring 234 is used to reset the slider 232, and the cooperating spring 235 is used to achieve elastic sliding of the locking block 233 relative to the slider 232. One side of the slider 232, near the locking switch wrench, has a triangular structure, which cooperates with the rotating part 2312 of the locking switch wrench 231.

[0036] A locking mechanism is provided at the connection between the seat 21 and the seat support mechanism 22, and the locking block 233 engages with this locking mechanism. Specifically, the tray 211 at the bottom of the seat is provided with a first latch 2111, and the support plate 221 of the seat support mechanism 22 is provided with a plurality of second latches 2211 distributed circumferentially along the support plate. The first latches 2111 and the second latches 2211 engage to form a locking mechanism, and the locking head 2331 of the locking block 233 engages with this locking mechanism.

[0037] The deep notch 2313 allows the elastic locking component to unlock the horizontal circumferential rotation of the seat 21 through elastic extension and retraction, while the shallow notch 2314 allows the elastic locking component to lock the horizontal circumferential rotation of the seat 21 through elastic extension and retraction.

[0038] For aesthetic purposes, the bottom of the seat 21 is provided with a cover plate 213, which covers the tray 211 and the support plate 221.

[0039] In the unlocked state of the rotating locking mechanism 23, the user can rotate the seat 21. When rotated to a certain position, the user can operate the locking switch wrench 231 to rotate it. The triangular structure of the slider 232 disengages from the deep recess 2313 of the locking switch wrench 231. During the disengagement process, the slider 232 moves toward the locking engagement structure. The locking block 233 also moves with the slider 232. The locking head of the locking block 233 engages in the aligned first slot 2111 and second slot 2211. At this time, as the locking switch 231 continues to rotate, the slider 232 continues to move. Since the locking block 233 has been engaged in the locking engagement structure and cannot move further, the locking block 233 moves relative to the slider 232 under the action of the engagement spring 235. When the locking switch 231 rotates to the point where the triangular structure of the slider contacts the connecting protrusion between the deep and shallow recesses, the slider 232 is completely pushed out of the deep recess 2313 of the locking switch 231. The locking switch 231 continues to rotate, and the triangular structure of the slider 232 enters the shallow recess 2314 of the locking switch 231. The slider 232 then moves away from the locking engagement structure, while the locking block 233 remains engaged in the locking engagement structure. At this point, the locking action is completed. When unlocking is required, the locking switch lever 231 is rotated in the opposite direction. The slider 232 disengages from the shallow notch 2314 of the locking switch lever 231 and enters the deep notch 2313. Under the action of the return spring 234, the slider 232 returns to its original position away from the locking engagement structure. The locking block 233 moves with the slider 232, disengaging from the locking engagement structure, thus unlocking the seat. At this time, the user can rotate the seat.

[0040] like Figures 1 to 7 As shown, this utility model also provides an integrated table and chair, which includes a movable base assembly 1, a seat assembly 2 and a table assembly 3 disposed on the base assembly 1.

[0041] The seat assembly 2 includes a seat 21, a seat support mechanism 22, and the aforementioned rotation locking mechanism 23. The seat 21 is mounted on the seat support mechanism 22, which is mounted on the base assembly 1. The seat 21 is rotatable relative to the seat support mechanism 22. The rotation locking mechanism 23 is used to lock the horizontal circumferential rotation of the seat 21.

[0042] In this preferred embodiment, the seat support mechanism 22 is a gas spring structure, and its upper end (the upper end of the gas rod) passes through the support plate 221 and is connected to a height adjustment wrench 222. By operating the height adjustment wrench 222, the gas spring structure can be activated to adjust the seat height.

[0043] The seat 21 is equipped with a backrest 214, which is slidably mounted on the back panel of the seat 21. The structure enabling the backrest to slide up and down can be as follows: two symmetrical strip-shaped sliders 217 are provided on the backrest 214; two symmetrical strip-shaped sliding holes that cooperate with the sliders are provided on the back panel of the seat 21; multiple adjustment holes 216 are provided along the height direction on the backrest 214; and a backrest adjustment knob 215 is installed on the back panel of the seat 21. With the cooperation of the sliders and the sliding holes, the backrest 214 can slide up and down to adjust its height. The backrest adjustment knob 215 locks onto one of the adjustment holes 216 on the backrest 214 to adjust and lock the height of the backrest 214.

[0044] The table assembly 3 includes a tabletop 31 and a tabletop support mechanism 32. The tabletop 31 is mounted on the base assembly 1 via the tabletop support mechanism 31. In this preferred embodiment, the tabletop support mechanism 32 is a telescopic sleeve lifting structure with a tabletop height adjustment knob 321 installed on it. This telescopic sleeve structure is an existing structure, including an inner leg tube 322 and an outer leg tube 323. The inner leg tube 322 is installed in the outer leg tube 323. The upper end of the inner leg tube 322 is connected to the tabletop 31, and the lower part of the outer leg tube 323 is connected to the base assembly 1. A screw lifting device is provided in the inner leg tube 322. By using the tabletop height adjustment knob 321, the screw lifting device drives the inner leg tube 322 and the tabletop 31 on it to move up and down, thereby adjusting the tabletop height.

[0045] The bottom of the tabletop 31 is provided with a tabletop front-to-back adjustment mechanism 33. This mechanism includes a slide rail 331, a fixed plate 332, and a tabletop adjustment lever 333. The fixed plate 332 is fixed to the tabletop support mechanism 32. Two slide rails 331 are symmetrically fixed on the left and right sides of the bottom of the tabletop 31, and the two sides of the fixed plate 332 slide in contact with these two slide rails 331 respectively. By pulling the tabletop 31, it can move back and forth relative to the fixed plate 332 via the slide rails 331, thereby adjusting the distance between the tabletop 31 and the seat 21. One side of the fixed plate 332 has multiple slots 3321 arranged front-to-back. The tabletop adjustment lever 333 is rotatably mounted on the slide rail 331 near the fixed plate on the side with the slots, and a torsion spring is also provided at the rotatable connection of the tabletop adjustment lever 333. The end of the tabletop adjusting lever 333 facing the fixed plate 332 has a locking block 3331, which engages with the locking groove 3321 to lock the tabletop position. In use, pressing the tabletop adjusting lever 333 overcomes the force of the torsion spring, causing one end of the lever to move closer to the tabletop 31, while the locking block 3331 at the other end disengages from the locking groove 3321 of the fixed plate 332. At this point, the tabletop 31 can be moved back and forth. Once in the desired position, releasing the tabletop adjusting lever 333 causes the locking block 3331 to engage with the locking groove 3321 of the fixed plate 332, achieving locking. Both ends of the slide rail 331 have slide rail limiting structures to prevent slippage.

[0046] The bottom of the tabletop is provided with a plastic outer panel 34, which covers the fixed plate 332 and the slide rail 331.
