Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchenware technology, and in particular to a wall cabinet lift mechanism. Background Technology
[0002] Tall cabinets (or wall cabinets) in the kitchen are often inconvenient to access items due to their height. To address this issue, traditional lift-up cabinets, consisting of a liftable gas spring structure and a cabinet basket, have been developed. The basket can be pulled down to retrieve items from the tall cabinet, thus alleviating the inconvenience to some extent.
[0003] However, the aforementioned traditional lifting cabinets still have the following drawbacks in practical applications:
[0004] 1) The support and cushioning are only achieved by gas struts. When the load exceeds the gas strut's capacity, the cabinet basket will have difficulty rebounding and returning to its original position. If a gas strut with a larger load capacity is replaced, the cabinet basket will be difficult to pull down and will be hard to control, making it inconvenient to retrieve items.
[0005] 2) The product lacks a load-bearing component. The load-bearing capacity of the gas spring is fixed, which determines that the load-bearing capacity of the cabinet basket is also fixed. The load-bearing capacity of the cabinet basket cannot be dynamically adjusted, resulting in a lack of product functionality and an inability to meet the market's demand for product functionality diversity. Utility Model Content
[0006] In view of the shortcomings of the prior art, this utility model provides a hanging cabinet lift to overcome the deficiencies in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A wall-mounted cabinet lift includes lifting components that support cabinet baskets from both sides, and a steering shaft connecting the lifting components.
[0009] The lifting assembly includes a double-hinge oscillating linkage strut structure mounted on the lifting box, and a gas spring mounted inside the lifting box.

[0035] Furthermore, if terms such as "first" or "second" are used for descriptive purposes only, they are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, components or parts, and should not be construed as indicating or implying relative importance.
[0036] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0037] Please also refer to Figure 1-8 This utility model provides a hanging cabinet lift, including two sets of lifting components 2 that support the cabinet basket 1 from both sides. The two sets of lifting components 2 have the same structure and are symmetrically arranged, and a steering shaft 3 connects the two sets of lifting components 2.
[0038] The lifting assembly 2 includes a double-hinge oscillating linkage strut structure mounted on the lifting box 21, and a gas spring 22 and a force-adding assembly mounted inside the lifting box 21.
[0039] The lifting box 21 has an arc-shaped guide and limiting groove 211 on its side plate. The arc-shaped guide and limiting groove 211 is provided with a limit. The arc-shaped guide and limiting groove 211 is used to guide and limit the force-adding guide wheel group 52 in the force-adding assembly.
[0040] The double-hinge sway linkage support structure includes a first support rod 41 and a second support rod 42 arranged in parallel. The high ends of the first support rod 41 and the second support rod 42 are respectively hinged to the first and second points on the side panel of the cabinet basket 1, and the low end of the first support rod 41 is hinged to the third point on the side panel of the lifting box 21. The low end of the second support rod 42 is hinged to the steering shaft 3. When the highest position of the cabinet basket 1 is manually pulled out, under the joint support of the two high ends and the two low ends of the double-hinge sway linkage support structure, the cabinet basket 1 smoothly descends to the lowest position in an arc-shaped trajectory, making it convenient to retrieve items inside the cabinet basket 1. When the lowest position of the cabinet basket 1 is manually pushed up, under the joint support of the two high ends and the two low ends of the double-hinge sway linkage support structure, the cabinet basket 1 smoothly rises to the highest position in an arc-shaped trajectory, thereby returning the cabinet basket 1 to its original position inside the cabinet.
[0041] The gas spring 22 has one end hinged inside the lifting box 21 and the other end connected to the steering shaft 3 via the crank 221. Since the second support rod 42 is connected to the steering shaft 3, and the gas spring 22 is also connected to the steering shaft 3 via the crank 221, when the cabinet basket 1 is raised or lowered, the steering shaft 3 drives the gas spring 22 to extend or retract via the crank 221, thereby giving the gas spring 22 a supporting and buffering function.
[0042] The force-adding assembly includes a force-adding cylinder 51, a force-adding guide wheel assembly 52, a force-adding pin 53, a force-adding spring 54, a force-adding hook 55, a conversion fork 56, and a pin button 57;
[0043] The high end of the booster cylinder 51 is rotatably mounted in the lifting box 21 via the booster hinge shaft 59, and the low end of the booster cylinder 51 points toward the booster guide wheel assembly 52.
[0044] The force-adding guide wheel assembly 52 is slidably installed in the arc-shaped guide limiting groove 211 on the side plate of the lifting box 21, and the force-adding guide wheel assembly 52 is connected to the first support rod 41 through the force-adding pin 53;
[0045] The force-adding spring 54 is installed inside the force-adding cylinder 51. The lower end of the force-adding spring 54 is connected to the force-adding guide wheel assembly 52, and the higher end of the force-adding spring 54 points towards and approaches the force-adding hook 55.
[0046] One end of the force-adding hook 55 is hinged to the force-adding hinge shaft 59, and the other end is connected to the high end of the conversion fork 56;
[0047] The high end of the shift fork 56 is connected to the force-applying hook 55, and the low end of the shift fork 56 is connected to the latch button 57.
[0048] The latch button 57 is located on the housing of the lifting box 21.
[0049] The basic working principle of the force-adding component is as follows: When the pin button 57 is pressed, the pin button 57 drives the conversion fork 56, the conversion fork 56 drives the force-adding hook 55, so that the force-adding hook 55 hooks the force-adding spring 54, so that the lower end of the force-adding spring 54 is connected to the force-adding guide wheel assembly 52, and the higher end of the force-adding spring 54 is connected to the force-adding hinge shaft 59. At the same time, since the force-adding guide wheel assembly 52 is connected to the first support rod 41 through the force-adding pin 53, the force of the force-adding spring 54 can be indirectly applied to the first support rod 41, thereby playing the role of adding force to the cabinet basket 1.
[0050] When the cabinet basket 1 is raised or lowered by external force, the force-applying cylinder 51 and the force-applying spring 54 rotate around the axis of the force-applying hinge shaft 59. At the same time, under the action of the arc-shaped guide limit groove 211 on the side plate of the lifting box 21, the extension and contraction of the force-applying spring 54 during the raising and lowering of the cabinet basket 1 changes with the deflection angle of the force-applying cylinder 51. Finally, the force of the force-applying spring 54 applies a force-applying effect to the cabinet basket 1.
[0051] The advanced working principle of the force-adding components is as follows: The two sets of lifting components 2 on both sides of the cabinet basket 1 use two different types of force-adding springs with different elastic forces. Different force-adding levels can be obtained by pressing the left and right latch buttons in combination, such as:
[0052] With the left and right latches in neutral, both latches can be pulled out to provide 0-2kg load-bearing force from the force-adding component.
[0053] In first gear, press the left pin button in and pull the right pin button out; the force-adding component provides a load-bearing force of 2-4 kg.
[0054] Second position: pull out the left pin button and press in the right pin button; the force-adding component provides a load-bearing force of 3-6kg.
[0055] Three speed settings; press both left and right latch buttons to engage, and the booster assembly provides a 5-10kg load-bearing boost.
[0056] Compared to existing technologies, the wall cabinet lift in this case, by setting up a force-reinforcing component inside the lift box, ensures that the cabinet basket can automatically spring back to its original position from the low position and return to the high position of the cabinet, eliminating the need to manually push the cabinet basket back into place. It has a high degree of automation and is easy to use.
[0057] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
