Description

Technical Field

[0001] This utility model relates to an integrated table and chair, specifically an adjustable integrated table and chair, belonging to the field of table and chair technology. Background Technology

[0002] Tables and chairs are commonly used tools in offices. Workers use them to work, but the current inability to adjust the angle of the tables and chairs can affect their spines. Different workers have different heights, and it is impossible to adjust the height of the tables and chairs according to their own needs. At the same time, prolonged sitting can easily harm the health of workers, and they need to exercise after sitting for a period of time. Tables and chairs are very common tools with a wide range of uses. In terms of teaching tables and chairs, most tables and chairs are separate, which is inconvenient to use and does not have an adjustment function. Therefore, integrated adjustable tables and chairs have emerged.

[0003] A search revealed a Chinese patent with publication number CN220327112U, which discloses an integrated adjustable table and chair, including a table opening and a base plate. A support plate is connected between the lower left side of the table opening and the upper left side of the base plate. Side plates are respectively connected between the lower parts of the front and rear side walls of the table opening and the front and rear parts of the upper side of the base plate. A sliding groove is provided on the right side of the base plate, and a connecting plate is slidably mounted inside the sliding groove. Limiting grooves are provided on the front and rear sides of the connecting plate. Limiting blocks are respectively threaded through the right sides of the front and rear side walls of the base plate, with one end of the limiting block inserted into the limiting groove. Connecting components are respectively hinged to the front and rear parts of the right side wall of the connecting plate. A support leg is connected to the other end of the connecting component. A seat plate is connected between the other ends of the two sets of support legs. Support legs are respectively connected to the two corners of the lower right side of the seat plate.

[0004] While the aforementioned device forms a chair with support leg one, seat board, support leg two, and backrest, and the distance between the chair and the table opening and tabletop can be adjusted by pulling out a connecting plate from the slide, making it convenient to use, the backrest can be folded onto the seat board, and the entire chair can rotate 90° towards the table opening. The connecting plate can be retracted into the slide, allowing the chair to be stored under the table opening, reducing space occupation. The chair's movement via the connecting plate will not cause tripping hazards to people behind it. However, the height of the table in this integrated adjustable table and chair is adjusted via multiple manual telescopic rods. Operation requires simultaneously releasing the limiting devices of multiple manual telescopic rods before adjusting the tabletop height, a time-consuming and laborious process, inconvenient for a single person. Therefore, we provide an adjustable integrated table and chair to solve these problems. Utility Model Content

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The system includes a table lifting mechanism 1, which includes a storage rack 101. The storage rack 101 has two symmetrical storage slots 102, a square slide 103, and two sets of symmetrical circular slides 104. Both sets of circular slides 104 are slidably connected to circular slide rods 105. The circular slide rods 105 are fixedly connected to a tabletop 106. The tabletop 106 is fixedly connected to a square slide rod 107. The square slide rod 107 has a first threaded hole 108. The first threaded hole 108 is threadedly connected to a threaded post 109. The threaded post 109 is fixedly connected to a first rotating disk 110. The first rotating disk 110 is rotatably connected to the lower surface of the storage rack 101.

[0025] The upper surface of the first rotating disk 110 can cover the lower surface of the square sliding rod 107. The rotating connection between the first rotating disk 110 and the storage rack 101 is reinforced with high-strength material. By rotating the first rotating disk 110 left and right, the square sliding rod 107 is driven to slide up and down inside the square sliding groove 103. At the same time, the two sets of symmetrical circular sliding rods 105 are driven to slide up and down inside the circular sliding groove 104, thereby driving the tabletop 106 to rise and fall vertically. The table height can be easily adjusted by raising and lowering the tabletop 106, thus achieving the purpose of convenient table height adjustment of this device. This solves the problem that the height adjustment of the table in the above-mentioned integrated adjustable table and chair is achieved by using multiple manual telescopic rods. During operation, it is necessary to release the limiting devices of multiple manual telescopic rods at the same time before adjusting the height of the tabletop. This process is time-consuming and laborious, and it is inconvenient for a single person to operate, which brings inconvenience to the user. This device achieves the convenience of use.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The table lifting mechanism 1 is equipped with a table and chair connecting mechanism 2. The table and chair connecting mechanism 2 includes a support frame 201, which is fixedly connected to the storage rack 101. The support frame 201 is fixedly connected to two mutually symmetrical arc-shaped slide rails 202. Both arc-shaped slide rails 202 are provided with arc-shaped slide grooves 203. The arc-shaped slide grooves 203 are slidably connected to sliders 204. The sliders 204 are rotatably connected to connecting plates 205. The connecting plates 205 are rotatably connected to support seats 206. The support seats 206 are equipped with rollers 207. The support seats 206 are fixedly connected to support rods 208. The support rods 208 are fixedly connected to support blocks 209.

[0027] Here, the support base 206 and the roller 207 form a roller assembly. When the roller 207 and the support block 209 are supported on the ground, the support rod 208 can be kept in a horizontal state. By lifting the chair backward and then pushing and pulling the chair along the sliding direction of the arc-shaped slide rail 202, the two mutually symmetrical sliders 204 are driven to slide in the arc-shaped slide groove 203 in the same direction as the chair. At the same time, the two mutually symmetrical connecting plates 205 move in the same direction as the sliders 204, and the two mutually symmetrical rollers 207 roll in the same direction as the sliders 204. Thus, most of the chair can be stored inside the support frame 201 or moved out of the support frame 201, realizing the purpose of this device to conveniently pull out and store the chair.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The table and chair connecting mechanism 2 is equipped with a lifting chair mechanism 3. The lifting chair mechanism 3 includes a connecting frame 301, which has a second threaded hole 302. The connecting frame 301 is fixedly connected to two sets of mutually symmetrical sliding tubes 303. Both sets of sliding tubes 303 are fixedly connected to the support rod 208. Both sets of sliding tubes 303 have sliding cavities 304. The sliding cavities 304 are slidably connected to the lifting rod 305. The lifting rod 305 is fixedly connected to the seat plate 306. The seat plate 306 is fixedly connected to the backrest 307. The seat plate 306 has a rotating groove 308. The rotating groove 308 has a through hole 309. The rotating groove 308 is rotatably connected to a second rotating disk 310. The second rotating disk 310 is fixedly connected to a rotating block 311, which is located inside the rotating groove 308. The second rotating disk 310 is fixedly connected to a threaded rod 312, which passes through the through hole 309 and is threadedly connected to the second threaded hole 302.

[0029] The connection between the second rotating disk 310 and the rotating groove 308 is reinforced with a high-strength material. When the chair height is not adjusted, the rotating groove 308 is sealed with a matching plug. By rotating the rotating block 311 left and right, the second rotating disk 310 is driven to rotate left and right inside the rotating groove 308, and the threaded rod 312 is driven to rotate left and right, thereby driving the connecting frame 301 to move up and down. At the same time, the two sets of mutually symmetrical lifting rods 305 slide up and down inside the sliding cavity 304, and the seat plate 306 moves vertically up and down. By moving the seat plate 306 vertically up and down, the height of the chair can be adjusted, thus achieving the purpose of convenient chair height adjustment of this device.

[0030] In use, this invention works as follows: Rotating the first rotating disk 110 left and right causes the square sliding rod 107 to slide up and down inside the square sliding groove 103, simultaneously causing two sets of symmetrical circular sliding rods 105 to slide up and down inside the circular sliding groove 104. This causes the tabletop 106 to rise and fall vertically, allowing for convenient height adjustment of the table, thus achieving the purpose of convenient table height adjustment. Rotating the rotating block 311 left and right causes the second rotating disk 310 to rotate left and right inside the rotating groove 308, simultaneously causing the threaded rod 312 to rotate left and right, thereby causing the connecting frame 301 to move up and down. Simultaneously, this causes the two sets of symmetrical lifting rods 305 to move up and down inside the sliding cavity 304. The chair slides down, simultaneously causing the seat plate 306 to move vertically up and down. This vertical movement of the seat plate 306 allows for height adjustment, achieving the purpose of convenient chair height adjustment. By lifting the chair backward and then pushing and pulling it along the sliding direction of the arc-shaped slide rail 202, two symmetrical sliders 204 slide in the arc-shaped slide groove 203 in the direction of chair movement. Simultaneously, two symmetrical connecting plates 205 move in the same direction as the sliders 204, and two symmetrical rollers 207 roll in the same direction as the sliders 204. This allows most of the chair to be stored inside the support frame 201 or moved outside the support frame 201, achieving the purpose of conveniently pulling out and storing the chair.
