[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.
[0021] Please refer to the attached Figure 1-Figure 3As shown, the utility model provides a technical solution: an extendable cabinet for whole-house customization, comprising a cabinet body 10 and an extension cabinet 20, the lower ends of the cabinet body 10 and the extension cabinet 20 away from each other are provided with wheels 11, the extension cabinet 20 is slidably connected to the inner wall of the cabinet body 10, and the side of the extension cabinet 20 close to the cabinet body 10 is fixedly connected with two L-shaped fixing blocks 203, a telescopic mechanism that can pull the extension cabinet 20 to retract inside the cabinet body 10 is provided between the cabinet body 10 and the extension cabinet 20, the telescopic mechanism includes four circular pulleys 14 symmetrically arranged at the four corners of the upper end of the inner wall of the cabinet body 10, and L-shaped sliding grooves 101 are opened on both sides of the inner wall of the cabinet body 10 along the side of the cabinet body 10. The four circular pulleys 14 are respectively slidably installed in the two L-shaped slide grooves 101. The four circular pulleys 14 are fixedly connected to a circular shaft 15 on one side away from the inner wall of the two L-shaped slide grooves 101. A first transmission rod 17 is provided between two circular shafts 15 located on the same side of the four circular shafts 15. The two circular shafts 15 near one end of the extension cabinet 20 among the four circular shafts 15 respectively pass through the two L-shaped fixed blocks 203 and are rotatably connected to the two L-shaped fixed blocks 203. The horizontal length of the cabinet body 10 is greater than the horizontal length of the extension cabinet 20. In the process of the extension cabinet 20 being retracted into the cabinet body 10, the extension cabinet 20 cannot be completely retracted into the cabinet body 10 to avoid being affected by the first transmission rod 17.
[0022] Specifically, through the telescopic mechanism, when the circular pulley 14 at the corner of the L-shaped slide 101 is adjusted to move vertically downward in the L-shaped slide 101, the circular pulley 14 on the side close to the extension cabinet 20 will be pulled to move horizontally in the L-shaped slide 101 through the transmission of the two circular shafts 15 and the first transmission rod 17, and the first transmission rod 17 is converted from a horizontal state to an inclined state. During the continuous movement of the two circular pulleys 14 in the L-shaped slide 101, the angle between the first transmission rod 17 and the horizontal direction gradually increases, further making the horizontal distance between the two circular pulleys 14 gradually smaller, so that the L-shaped fixing block 203 pulls the extension cabinet 20 to retract into the cabinet body 10, which is used to store the extension cabinet 20 in the cabinet body 10. Conversely, the extension cabinet 20 can be extended out of the cabinet body 10.
[0023] In one embodiment of the present invention, Figure 2 As shown, the L-shaped slide 101 consists of a horizontal groove and a vertical groove. The two circular pulleys 14 are both arranged in the horizontal groove of the L-shaped slide 101. Both ends of the first transmission rod 17 are rotatably connected to the circular shaft 15. When the circular pulley 14 at the corner of the L-shaped slide 101 is adjusted to move in the vertical groove of the L-shaped slide 101, the first transmission rod 17 will pull or push the circular pulley 14 on the side close to the extension cabinet 20 to move.
[0024] In one embodiment of the present invention, Figure 2As shown, multi-stage cylinders 13 are fixedly installed on one side of the vertical grooves near the two L-shaped slides 101 on both sides of the inner wall of the cabinet 10, and a connecting block 16 is fixedly installed on the output end of the multi-stage cylinder 13. The end of the connecting block 16 away from the output end of the multi-stage cylinder 13 is fixedly connected to the circular pulley 14 near the vertical groove. By starting the multi-stage cylinder 13, the telescopic end of the multi-stage cylinder 13 drives the connecting block 16 to move along the side of the vertical groove of the L-shaped slide 101, and further drives the circular pulley 14 at the corner of the L-shaped slide 101 to move vertically downward in the L-shaped slide 101.
[0025] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, an elongated slot 201 is provided at the upper end of the extension cabinet 20, in which a support plate 21 is slidably installed. The upper end of the support plate 21 is flush with the upper surface of the cabinet body 10, and first springs 22 are fixedly installed at both ends of the support plate 21 and the inner wall of the elongated slot 201.
[0026] Specifically, by pressing the support plate 21, the support plate 21 squeezes the two first springs 22 and is stored in the elongated groove 201, and then the multi-stage cylinder 13 is adjusted to store the extension cabinet 20 in the cabinet body 10. Conversely, when the extension cabinet 20 is fully extended from the cabinet body 10, under the elastic force of the two first springs 22, the support plate 21 can be pushed to slide upward in the elongated groove 201 and be level with the upper end of the cabinet body 10, thereby increasing the area of the cabinet countertop.
[0027] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, both sides of the support plate 21 are provided with a limiting groove 211, and an extension plate 25 is slidably installed in the two limiting grooves 211. The connection between the upper end of the support plate 21 and the extension plate 25 is set in an inclined triangular shape, so that the connection between the support plate 21 and the extension plate 25 has no sharp corners to prevent the sharp corners from scratching the operator. The inner walls of the limiting grooves 211 are fixedly connected with fixing rods 23 at both ends. The two fixing rods 23 pass through the extension plate 25 and are slidably connected to the extension plate 25. The extension plate 25 and the inner wall of the limiting grooves 211 are fixedly connected. Two second springs 24 are fixedly installed between the walls. The two second springs 24 are respectively slidably sleeved on the outer surfaces of the two fixed rods 23. When the extension cabinet 20 is retracted into the cabinet body 10, the two extension plates 25 respectively squeeze the two second springs 24 and retract into the two limiting grooves 211. When the support plate 21 extends out of the elongated groove 201, the elastic force of the two second springs 24 can make the two extension plates 25 extend out of the two elongated grooves 201 respectively, thereby increasing the countertop area of the cabinet.
[0028] In one embodiment of the present invention, Figure 1As shown, a first cabinet door 12 and a second cabinet door 26 are respectively provided on one side of the cabinet body 10 and the extension cabinet 20. A vertical side of the first cabinet door 12 is hinged to the cabinet body 10, and a lower end of the second cabinet door 26 is hinged to the extension cabinet 20. A pull-out assembly is provided between the second cabinet door 26 and the extension cabinet 20. By setting the first cabinet door 12 and the second cabinet door 26, it is convenient to take and put items inside the cabinet.
[0029] In one embodiment of the present invention, Figure 3 As shown, the pull-out assembly includes four support blocks 262 fixedly mounted on the side of the second cabinet door 26 close to the interior of the extension cabinet 20, two slide rods 263 are fixedly mounted between the four support blocks 262, and round blocks 202 are fixedly connected on both sides of the inner wall of the extension cabinet 20. Second transmission rods 27 are rotatably mounted on the two round blocks 202, and the ends of the two second transmission rods 27 away from the two round blocks 202 are fixedly connected to the sliders 28. The two slide rods 263 respectively penetrate the two sliders 28 and are slidably connected to the two sliders 28 respectively. The second cabinet door 26 is away from the four A groove 261 is provided at the upper end of one side of the support block 262. When the extension cabinet 20 is stored in the cabinet body 10 and the cabinet needs to be opened, the handle on the first cabinet door 12 is first pulled to open the first cabinet door 12, and then the groove 261 on the second cabinet door 26 is manually pulled to rotate the lower end of the second cabinet door 26, driving the slider 28 to slide on the slide rod 263 between the two support blocks 262, and further driving the second transmission rod 27 to rotate on the round block 202 away from the slider 28, so that the second cabinet door 26 can be opened, making it convenient to store items in the cabinet.
