Description

Technical Field

[0001] This utility model relates to the field of lifting baskets, and in particular to a simple door panel linkage lifting basket. Background Technology

[0002] Currently, most mainstream electric pull-out basket products adopt an integrated design, where the basket, drive motor, and transmission components are integrated into a single unit housed within the wall cabinet. During operation, the basket moves downwards until it fully extends out of the cabinet, while the cabinet itself remains stationary. Because wall cabinets must balance user convenience with the overall aesthetics of the kitchen during installation, their installation height is typically set low. This results in limited vertical space between the bottom of the basket and the kitchen countertop when it reaches its lowest position. This makes it difficult for users to temporarily place tall kitchen appliances such as rice cookers and kettles on the countertop below the basket, severely limiting the countertop's functionality and creating a risk of collision and interference between the basket and items, thus reducing the flexibility of kitchen space layout. Furthermore, to achieve smooth lifting and lowering of the basket, these products usually require multiple guide rails for traction and guidance, leading to a more complex overall structure, an increased number of parts, and consequently, higher manufacturing costs.

[0003] Based on the above, the existing electric lifting baskets need further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a simple door panel linkage lifting basket. By using a reverse traction component to pull the movable door panel to produce synchronous lifting and lowering opposite to the basket, the basket is fully extended while the descent height is significantly reduced, thereby reducing the restrictions on the use of the countertop and improving the practicality of the basket.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a simple door panel linkage lifting basket, including a drive device, a linkage lifting mechanism, a basket lifting bracket, a storage basket, and a base plate. The drive device is located on the upper side of the basket lifting bracket and connected to the base plate through the basket lifting bracket. The basket lifting brackets are symmetrically arranged and are connected to the drive device for transmission. The storage basket is arranged between the basket lifting brackets. The linkage lifting mechanism includes a reverse traction component, a movable side plate, and a guide base plate. One end of the reverse traction component is connected to the basket lifting bracket, and the other end is hinged to the movable side plate. The movable side plate is provided with a first sliding point and a second sliding point. The first sliding point and the second sliding point are slidably located on the guide base plate. When the basket is lifted, the reverse traction component pulls the movable side plate to lift in the opposite direction. The movable side plate is connected to a movable door panel.

[0006] Compared with existing technologies, this utility model converts the lifting driving force of the pull-out basket into a reverse force through a reverse traction component, driving the movable side plate to lift and lower synchronously with the pull-out basket. While ensuring the pull-out basket is fully extended, it significantly reduces its descent height, allowing sufficient space between the bottom of the pull-out basket and the kitchen countertop, thereby reducing restrictions on countertop use and improving product practicality. At the same time, double sliding points are set on the movable side plate, allowing the movable side plate and the guide base plate to be guided by a double pulley groove guide mechanism. While ensuring stable and reliable sliding, it achieves component simplification and structural simplification, effectively reducing production and manufacturing costs.

[0007] Preferably, the traction assembly includes a fixed pulley, a connecting rope, a traction wheel, and a rocker arm. The connecting rope is wound around the fixed pulley, with one end connected to the pull-out basket lifting bracket and the other end connected to the traction wheel. The traction wheel is slidably mounted on the guide base plate. One end of the rocker arm is hinged to the traction wheel, and the other end is hinged to the movable side plate. The combination of the fixed pulley and the connecting rope can convert the lifting of the pull-out basket lifting bracket into a reverse lifting driving force, driving the traction wheel to lift in the opposite direction. The rocker arm swings to drive the movable side plate and the movable door plate connected to it to lift in the opposite direction.

[0008] Preferably, a first guide groove is provided on the guide base plate, and a first guide wheel is provided at the first sliding point. The first guide wheel is slidably disposed on the first guide groove. The first guide groove includes a first inclined groove section and a first vertical section. When the traction wheel slides, the first guide wheel enters the first vertical section through the first inclined groove section, or enters the first inclined groove section through the first vertical section. When the basket is in the rising state, the first guide wheel is at the end of the first inclined groove section away from the first vertical section. As the basket descends, the first guide wheel begins to move in the first inclined groove section. Therefore, the movement of the first guide wheel and the movable side plate are completely synchronized.

[0009] Preferably, the guide base plate is provided with a traction groove, and the second sliding point is provided with a second guide wheel. The second guide wheel is slidably mounted on the traction groove. The traction groove includes a locking position, a second inclined groove section, and a second vertical section. The second vertical section is connected to the locking position through the second inclined groove section. The traction wheel slides on the second vertical section. When the basket is in the rising state, the second guide wheel is located in the locking position. When the basket changes from the rising state to the falling state, the second guide wheel moves from the locking position through the second inclined groove section into the second vertical section. When the basket falls, the rocker arm swings at a certain angle. The second guide wheel is initially stationary in the locking position. As the basket continues to fall, the rocker arm pulls the movable side plate to rise as a whole. At this time, the second guide wheel begins to enter the second inclined groove section and slides upward along the second inclined groove section and the second vertical section. Therefore, the movement of the second guide wheel starts slightly later than that of the movable side plate, thus forming a movement trajectory in which the upper part of the movable side plate first tilts outward, then the lower part also tilts outward, and finally rises vertically, thus avoiding the upper fixed door panel and completing the rise.

[0010] Preferably, the movable side plate is provided with a horizontal guide groove, and a sliding shaft is slidably provided on the horizontal guide groove. A third hook is sleeved on the sliding shaft. A transition wheel and a fourth hook are provided on the side of the movable side plate near the third hook. A second tension spring is hooked between the third hook and the fourth hook, and the second tension spring is arranged around the transition wheel.

[0011] Preferably, the guide base plate is provided with a second guide groove, and a third guide wheel is slidably provided on the second guide groove. The sliding shaft passes through the third hook, the horizontal guide groove and the third guide wheel in sequence. When the movable side plate moves horizontally, the horizontal guide groove moves accordingly, so that the sliding shaft changes from being located at one end of the horizontal guide groove to being located at the other end. When the movable side plate slides vertically, the horizontal guide groove pushes the sliding shaft to slide vertically.

[0012] Preferably, the rocker arm is provided with a first hook, and the movable side plate is provided with a second hook on the side near the second guide wheel. A first tension spring is connected between the first hook and the second hook.

[0013] When the movable door panel is closed, its own weight causes its top to tilt outward, making it impossible for the outer surface of the movable door panel to be flush with the upper fixed door panel. Therefore, a first tension spring and a second tension spring are installed. The auxiliary tension of the tension springs overcomes the tilting force of the movable door panel, making the upper and lower door panels flush.

[0014] Preferably, the movable side panel is provided with an adjustment connector, which includes a door panel hanger and an adjustment plate. The door panel hanger is used to connect the movable door panel, and the door panel hanger is hung on the adjustment plate and connected to the movable side panel through the adjustment plate. Through the adjustment plate connected to the movable side panel and the door panel hanger connected to the movable door panel, modular assembly of the movable door panel can be realized, making transportation and installation more convenient.

[0015] Preferably, the door panel hanger has a downward hook and fold, and the upper end of the adjustment plate has an extension. The hook and fold is hung on the extension. The extension can increase the contact area between the hook and fold and the adjustment plate, making the hanging more stable.

[0016] Preferably, the adjusting connector is provided with an adjusting assembly, which includes a first adjusting pin, a second adjusting pin, and a third adjusting pin. The hook-and-fold portion has a strip-shaped hole, and the extension portion has a through hole. The third adjusting pin passes through the adjusting plate and abuts against the door panel hanger to adjust the relative depth distance between the movable door panel and the pull-out basket. The second adjusting pin passes through the hook-and-fold portion and abuts against the extension portion to adjust the relative vertical distance between the movable door panel and the pull-out basket. The first adjusting pin passes through the strip-shaped hole and the through hole to adjust the relative horizontal distance between the movable door panel and the pull-out basket.

Detailed Implementation

[0037] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does 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, it should not be construed as a limitation of this utility model.

[0038] See Figures 1 to 9 ,as well as Figures 16 to 22This embodiment discloses a simple door panel linkage lifting basket 1, including a drive device 2, a linkage lifting mechanism 3, a basket lifting bracket 4, a storage basket 5, and a base plate 6. The drive device 2 is located on the upper side of the basket lifting bracket 4 and is connected to the base plate 6 through the basket lifting bracket 4. The basket lifting bracket 4 is symmetrically arranged and is connected to the drive device 2 for transmission. The storage basket 5 is arranged between the basket lifting brackets 4. The linkage lifting mechanism 3 includes a reverse traction component 8, a movable side plate 9, and a guide base plate 7. One end of the reverse traction component 8 is connected to the basket lifting bracket 4, and the other end is hinged to the movable side plate 9. The movable side plate 9 is provided with a first sliding point 91 and a second sliding point 92. The first sliding point 91 and the second sliding point 92 are slidably arranged on the guide base plate 7. When the basket is lifted, the reverse traction component 8 pulls the movable side plate 9 to lift in the opposite direction. The movable side plate 9 is connected to a movable door panel 13.

[0039] The reverse traction assembly 8 includes a fixed pulley 83, a connecting rope 84, a traction wheel 81, and a rocker arm 82. The connecting rope 84 is wound around the fixed pulley 83, with one end connected to the pull-out basket lifting bracket 4 and the other end connected to the traction wheel 81. The traction wheel 81 is slidably mounted on the guide base plate 7. One end of the rocker arm 82 is hinged to the traction wheel 81, and the other end is hinged to the movable side plate 9. The combination of the fixed pulley 83 and the connecting rope 84 converts the lifting driving force of the pull-out basket lifting bracket 4 into a reverse lifting driving force, driving the traction wheel 81 to lift and lower in the opposite direction. The rocker arm 82 swings, driving the movable side plate 9 and the movable door plate 13 connected to it to lift and lower in the opposite direction.

[0040] Specifically, there are two fixed pulleys 83, so that the lifting driving force can be distributed on the two fixed pulleys 83, preventing one fixed pulley 83 from falling off due to excessive pressure.

[0041] It also includes an installation part 85 extending to the opposite side linkage lifting mechanism 3. The installation part 85 is fixedly installed on the upper wall of the hanging cabinet and has a bent fixing member 86 on its lower side. The fixed pulley 83 is installed on the fixing member 86, and two fixing members 86 are provided accordingly.

[0042] The pull-out basket lifting bracket 4 is equipped with a connecting plate 41, which is perpendicular to the pull-out basket lifting bracket 4. One end of the pull-out basket lifting bracket 4 is connected to the connecting plate 41, and the other end of the connecting rope 84 is connected to the connecting plate 41. The connecting plate 41 is used to prevent the connecting rope 84 from being lifted by the driving device 2, so that the side of the connecting rope 84 connected to the pull-out basket lifting bracket 4 remains perpendicular. This conforms to the direction of the lifting driving force, ensuring that the driving force can be fully transmitted to the other side of the connecting rope 84. Furthermore, it minimizes the length of the connecting rope 84, saving materials.

[0043] The connecting rope 84 has screws 841 pressed at both ends. By adjusting the vertical height of the screws 841, the distance from both ends of the connecting rope 841 to the fixed pulley 83 can be adjusted to flexibly adapt to hanging cabinets of different heights.

[0044] See Figures 4 to 10 A first guide groove 72 is provided on the guide base plate 7, and a first guide wheel 911 is provided on the first sliding point 91. The first guide wheel 911 is slidably disposed on the first guide groove 72. The first guide groove 72 includes a first inclined groove section 721 and a first vertical section 722. When the traction wheel 81 slides, the first guide wheel 911 enters the first vertical section 722 through the first inclined groove section 721, or enters the first inclined groove section 721 through the first vertical section 722. The first inclined groove section 721 is disposed on the lower side of the first vertical section 722. When the basket 1 is in the rising state, the first guide wheel 911 is located at the lower end of the first inclined groove section 721. When the basket 1 begins to descend, the traction wheel 81 begins to rise synchronously. At this time, the first guide wheel 911 begins to slide in the first inclined groove section 721. Therefore, the movement of the upper end of the movable side plate 9 driven by the first guide wheel 911 is synchronous with the traction wheel 81. As the traction wheel 81 continues to rise, the first guide wheel 911 enters the first vertical section 722 from the first inclined groove section 721 to perform vertical movement.

[0045] The guide base plate 7 has a traction groove 71, and the second sliding point 92 is provided with a second guide wheel 921. The second guide wheel 921 is slidably mounted on the traction groove 71. The traction groove 71 includes a locking position 711, a second inclined groove section 712, and a second vertical section 713. The second vertical section 713 is connected to the locking position 711 through the second inclined groove section 712. The traction wheel 81 slides on the second vertical section 713. When the basket is in the rising state, the second guide wheel 921 is located at the locking position 711. When the basket changes from the rising state to the falling state, the second guide wheel 921 moves from the locking position 711 through the second inclined groove section 712 into the second vertical section 713. The locking position 711 is located at the lower end of the traction groove 71. When the pull-out basket 1 begins to descend, the traction wheel 81 begins to rise synchronously. At this time, the second guide wheel 921 is still in the locking position 711. After the traction wheel 81 rises a little more, the second guide wheel 921 enters the second inclined groove section 712 from the locking position 711. Therefore, the movement of the lower end of the movable side plate 9 driven by the second guide wheel 921 is not synchronized with the traction wheel 81, forming the effect that the upper end of the movable side plate 9 tilts outward first, the lower end tilts outward later, and then the outer angle returns to normal. This prevents the movable side plate 9 from colliding with the fixed door panel on the upper side when it rises, thus achieving the effect of avoiding air gaps.

[0046] The rocker arm 82 is hinged to the traction wheel 81 at one end, which is designated as the first hinge point 821. The rocker arm 82 is hinged to the movable side plate 9 at the other end, which is designated as the second hinge point 822. The second hinge point 822 is located between the first guide wheel 911 and the second guide wheel 921. The second hinge point 822, the first guide wheel 911, and the second guide wheel 921 are not on a straight line. Since the second hinge point 822, the first guide wheel 911, and the second guide wheel 921 are all located on the movable side plate 9 and can slide on the guide base plate 7, they form a rocker arm structure. When the traction assembly 8 pulls the second hinge point 822, the first guide wheel 911 slides upward first. Under the structural action of the rocker arm structure, the movable side plate 9 rotates around the second hinge point 822, and the second guide wheel 921 is subjected to downward pressure and remains stationary. The movable side plate 9 forms an inclined angle, thus allowing the movable door panel 13 to avoid the fixed door panel above it when it rises.

[0047] The length of the traction groove 71 is greater than the length of the first guide groove 72. Since the traction wheel 81 and the second guide wheel 921 both slide in the traction groove 71, the length of the traction groove 71 needs to take into account the distance between the traction wheel 81 and the second guide wheel 921. Therefore, the traction groove 71 is set to be longer than the first guide groove 72.

[0048] The movable side plate 9 is designed in a "Z" shape, and the height of the first guide wheel 911 is greater than the height of the second guide wheel 921, so that the first guide wheel 911 and the second guide wheel 921 form a diagonal positioning of the movable side plate 9, making the movable side plate 9 more stable when sliding.

[0049] Specifically, the traction groove 71 extends along the height direction of the basket 1.

[0050] The rocker arm 82 has a first hook 823, and the movable side plate 9 has a second hook 93 on the side near the second guide wheel 921. A first tension spring 931 is connected between the first hook 823 and the second hook 93. The movable side plate 9 has a horizontal guide groove 94, and a sliding shaft 941 is slidably provided on the horizontal guide groove 94. A third hook 942 is sleeved on the sliding shaft 941. A transition wheel 95 and a fourth hook 96 are provided on the side of the movable side plate 9 near the third hook 942. A second tension spring 961 is connected between the third hook 942 and the fourth hook 96, and the second tension spring 961 is arranged around the transition wheel 95. When the movable door panel 13 is in the closed state, the top of the movable door panel 13 will tilt outward due to its own weight, causing the outer surface of the movable door panel 13 to be unable to be flush with the upper fixed door panel. Therefore, the first tension spring 931 and the second tension spring 961 are provided. The auxiliary pulling force of the tension springs overcomes the tilting force of the movable door panel 13, making the upper and lower door panels flush.

[0051] The guide base plate 7 is provided with a second guide groove 73, and a third guide wheel 74 is slidably provided on the second guide groove 73. The sliding shaft 941 passes through the third hook 942, the horizontal guide groove 94, and the third guide wheel 74 in sequence. When the movable side plate 9 slides horizontally, it is guided by the cooperation of the sliding shaft 941 and the horizontal guide groove 94. After the horizontal sliding is completed, it is guided by the cooperation of the sliding shaft 941 and the second guide groove 73. On the one hand, since the sliding shaft 941 is set in the horizontal guide groove 94, its relative height on the movable side plate 9 is fixed. Therefore, when the movable side plate 9 moves vertically, the limiting effect of the second guide groove 73 on the sliding shaft 941 is also the limiting effect on the movable side plate 9, causing the point to move along the second guide groove 73. On the other hand... The second guide groove 73 limits the horizontal direction of the sliding shaft 941, which is equivalent to limiting the height of the movable side plate 9 when it moves horizontally, ensuring that the moving direction of the movable side plate 9 is accurate. After the horizontal movement is completed, since the sliding shaft 941 passes through the movable side plate 9 and the guide base plate 7, the second guide groove 73 must be opened on the guide base plate 7 to allow the movable side plate 9 to move smoothly up and down at that position. Therefore, the second guide groove 73, the horizontal guide groove 94 and the sliding shaft 941 are mutually coordinated and indispensable.

[0052] Specifically, the second hook 76 and the fourth hook 96 are both rotatably mounted on the movable side plate 9, and the third hook 942 can rotate relative to the sliding shaft 941. When the movable side plate 9 is raised and lowered, the lengths of the first tension spring 931 and the second tension spring 961 change continuously due to their elasticity, and the rotatable arrangement of the hooks can flexibly adapt to the relative positional changes of the two ends of the tension springs.

[0053] The cross-sections of the traction wheel 81, the first guide wheel 911, the second guide wheel 921, the third guide wheel 74, and the transition wheel 95 are U-shaped, forming a locking position on the outer periphery of the wheel body. This allows the traction wheel 81 and the second guide wheel 921 to be positioned in the traction groove 71, the first guide wheel 911 to be positioned in the first guide groove 72, and the third guide wheel 74 to be positioned in the second guide groove 73 without falling off. The transition wheel 95 uses this locking position to fix the second tension spring 961, preventing the second tension spring 961 from falling off the transition wheel 95.

[0054] See Figures 1 to 3 The linkage lifting mechanism 3 also includes a cover plate 31, which is disposed on the opposite side of the guide base plate 7 and surrounds the guide base plate 7 to form a movable cavity 32. The traction wheel 81, rocker arm 82 and movable side plate 9 are disposed in the movable cavity 32.

[0055] The cover plate 31 has a notch 311 on its upper side, and the connecting rope 84 passes through the notch 311 and connects to the traction wheel 81.

[0056] See Figure 5 The guide base plate 7 extends along the opposite side of the linkage lifting mechanism 3 with a flange 75. The width of the flange 75 is greater than the thickness of the traction wheel 81, the first guide wheel 91, the second guide wheel 92 and the third guide wheel 74 protruding from the back of the guide base plate 7, providing corresponding back side space for their sliding and ensuring smooth sliding.

[0057] See Figure 4 , Figures 11 to 12 The movable side panel 9 is equipped with an adjusting connector 97, which includes a door panel hanger 971 and an adjusting plate 972. The door panel hanger 971 is used to connect the movable door panel 13, and the door panel hanger 971 is hung on the adjusting plate 972 and connected to the movable side panel 9 through the adjusting plate 972. The movable door panel 13 is fixed to the linkage lifting mechanism 3 through the adjusting connector 97, realizing modular installation and low maintenance and replacement costs.

[0058] The door panel hanger 971 has a downward-facing hook 9711, and the upper end of the adjusting plate 972 has an extension 9721. The hook 9711 is hung on the extension 9721. The extension 9721 is used to increase the contact area between the hook 9711 and the adjusting plate 972, making the hanging more stable.

[0059] The adjustment plate 972 is L-shaped and includes a first contact surface 9723 and a second contact surface 9724. The first contact surface 9723 is connected to the door panel hanger 971, and the second contact surface 9724 is connected to the movable side plate 9 by fastening screws.

[0060] The adjusting connector 97 is equipped with an adjusting component 98, which includes a first adjusting pin 981, a second adjusting pin 982, and a third adjusting pin 983. The hook-and-fold portion 9711 has a strip-shaped hole 9712, and the extension portion 9721 has a through hole 9722. The third adjusting pin 983 passes through the adjusting plate 972 and abuts against the door panel hanger 971, used to adjust the relative depth distance between the movable door panel 13 and the pull-out basket 1. The second adjusting pin 982 passes through the hook-and-fold portion 9711 and abuts against the extension portion 9721, used to adjust the relative vertical distance between the movable door panel 13 and the pull-out basket 1. The first adjusting pin 981 passes through the strip-shaped hole 9712 and the through hole 9722, used to adjust the relative horizontal distance between the movable door panel 13 and the pull-out basket 1. By adjusting the three-dimensional direction of the movable door panel 13, the installation position of the movable door panel 13 can be made more precise.

[0061] See Figure 15 To enable the detachable connection of the storage basket 5, a connecting bracket 42 is provided on the opposite side of the pull-out basket lifting bracket 4, and mounting grooves 51 extend from both sides of the storage basket 5. The storage basket 5 is inserted into the connecting bracket 42 through the mounting grooves 51.

[0062] See Figure 2 The bottom plate 6 is provided with a control panel 11 for users to control the lifting and lowering of the basket 1.

[0063] See Figures 13 to 14 To facilitate installation, a positioning plate 12 is also included. The positioning plate 12 has a second hook 121 and an adjustment hole 122. The drive device 2 has a positioning hole 21, and the positioning plate 12 has two. During installation, the positioning plate 12 is first fixedly installed on the side wall of the cabinet. Then, the drive device 2 is hooked onto the hook 121 through the positioning hole 21. Finally, the installation height of the drive device 2 is finely adjusted by passing a set screw or screw through the adjustment hole 122 until it presses against the lower wall of the drive device 2.

[0064] See Figures 1 to 3 The pull-out basket lifting bracket 4 is provided with a "Z"-shaped curved plate 43. There are at least two curved plates 43, which are used to fix the pull-out basket 1 on the side wall of the hanging cabinet. Together with the positioning plate 12, they form a positioning of the pull-out basket 1 in three directions: the upper side, the left side, and the right side, so that the pull-out basket 1 is installed more stably.

[0065] The screw 841 is connected to a buffer component. The buffer component is made of materials including but not limited to high-performance polyurethane and rubber blocks. It is used to buffer the movement through deformation during lifting and lowering. It can effectively absorb the instantaneous impact force and vibration generated by the system during start-up, stop and movement, reduce structural fatigue and wear, avoid component damage or accidents caused by sudden jamming or impact at extreme positions, and make the movement more stable, quiet and smooth, thus improving the user experience.

[0066] The movable door panel 13 is connected to the connecting rope 84 via a traction wheel 81, a rocker arm 82, a movable side plate 9, a first tension spring 931, a second tension spring 961, and an adjusting connector 97. On one hand, the traction wheel 81, rocker arm 82, movable side plate 9, first tension spring 931, second tension spring 961, and adjusting connector 97 can distribute the weight of the movable door panel 13 and the resulting stress through multi-node hinges, slidable connections, or elastic tension springs, preventing the connecting rope 84 from breaking due to bearing the entire weight of the movable door panel 13, thus extending the service life of the connecting rope 84. On the other hand, there are four combinations of sliding points and grooves between the rocker arm 82 and the guide base plate 7, between the rocker arm 82 and the movable side plate 9, and between the movable side plate 9 and the guide base plate 7, as well as a combination of hooks and tension springs, so that the movable door panel 13 remains vertical or moves along a predetermined inclined path during the motion transmission process. The adjusting connector 97 makes precise adjustments to the installation position of the movable door panel 13 through fine adjustment. The six components work together to maintain precise control over the direction and position of the movable door panel 13 throughout the process, ensuring that the movable door panel 13 does not tilt or shake.

[0067] Compared with the prior art, this utility model converts the lifting driving force of the pull-out basket 1 into a reverse force through the reverse traction component 8, driving the movable side plate 9 to achieve synchronous reverse lifting and lowering with the pull-out basket 1. While ensuring that the pull-out basket 1 is fully extended, its lowering height is significantly reduced, allowing sufficient space to be maintained between the bottom of the pull-out basket 1 and the kitchen countertop, thereby reducing restrictions on the use of the countertop and improving the practicality of the product. At the same time, double sliding points are set on the movable side plate 9, so that the movable side plate 9 and the guide base plate 7 can be guided by the guide mechanism of double pulley grooves. While ensuring stable and reliable sliding, it realizes the simplification of components and structure, effectively reducing the production and manufacturing costs.

[0068] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
