[0034] Embodiment one

[0035] As shown in the accompanying drawings Figure 1 and the accompanying drawings Figure 2 The present embodiment provides a concealed lifting device, which comprises a storage bin 1, a lifting part 2 and a pull rod 3, wherein:

[0036] The storage bin 1 is a box-shaped structure with an open top, and both sides are provided with wing plates 1.1 for mounting. When the lifting device is installed, the two side wing plates can be fixed by fixing bolts 5, which is simple and convenient to install.

[0037] The lifting component 2 consists of a cover plate 2.1, a lifting ring 2.2 located at one end of the bottom surface of the cover plate, and a hook 2.3 located at the other end of the bottom surface of the cover plate. The size of the cover plate 2.1 matches the opening of the receiving chamber 1 and is used to cover the opening. A rib plate 2.4 is provided on the bottom surface of the cover plate 2.1 between the hook 2.3 and the lifting ring 2.2. The rib plate 2.4 has a waist-shaped groove 2.4.1. The waist-shaped groove 2.4.1 of the cover plate 2.1 is rotatably mounted on a pin 4, and the pin 4 is fixedly installed inside the receiving chamber 1. Preferably, the counterweight at the lifting ring 2.2 end of the lifting component 2 is greater than the counterweight at the hook 2.3 end.

[0038] The two ends of the pull rod 3 are fixedly installed inside the receiving compartment 1 and are used to be hooked by the hook 2.3, serving as the main load-bearing component. In this embodiment, the pull rod 3 is preferably fixed by welding (i.e., the two ends of the pull rod are welded to the wall of the receiving compartment). Furthermore, screw holes 3.1 are drilled at both ends of the pull rod 3 to facilitate the fixing of the lifting device to the mounting beam 7 using high-strength bolts 6. This distributes the force on the pull rod to the mounting beam, improving the reliability of the connection between the lifting device and the cabinet. Preferably, in this embodiment, the installation position of the pull rod 3 satisfies the following condition: when the lifting component 2 is in a vertical state, the center of the lifting ring 2.2 and the central axis of the pull rod 3 are on the same plane.

[0039] In practical use, the initial loading of the lifting device is as shown in the attached figure. Figure 1 As shown in the attached diagram, when lifting is required, Figure 5 As shown, first press down the end of the cover plate near the hook. At this time, one end of the lifting ring will lift up to expose the receiving chamber. Then, slightly lift the lifting ring upwards to make the lifting component vertical. Hook the crane hook onto the lifting ring. During the lifting process, the lifting component moves upwards to hook onto the tie rod. After the lifting is completed, return it to its original position.

[0040] Example 2

[0041] Based on Example 1, as shown in the appendix Figure 1 As shown, in this embodiment, the waist-shaped groove 2.4.1 is set as an inclined groove that slopes from the hook 2.3 toward the lifting ring 2.2. This structure is beneficial for adjusting the position of the lifting component by its own weight when it is unfolded, and for forming a displacement guide by the self-weight of the lifting ring when it is closed.

[0042] Example 3

[0043] As attached Figure 3 As shown, this embodiment provides an installation structure for a lifting device, including a mounting beam 7 and a concealed lifting device as described in Embodiment 1 or Embodiment 2. The top of the mounting beam 7 has a mounting hole, and the receiving compartment 1 of the concealed lifting device is installed in the mounting hole using fixing bolts 5. This embedded installation method for the lifting device results in a simple, convenient, and quick installation structure.

[0044] Example 4

[0045] Based on Example 3, as shown in the appendix Figure 4 As shown, in this embodiment, connection holes are provided on both sides of the mounting beam 7 opposite to the tie rod 3, and high-strength bolts 6 pass through the connection holes and are threadedly connected to the tie rod 3. This design allows the lifting device to distribute the force points to the mounting beam through the tie rod, effectively avoiding the problem that the lifting device is easily detached from the mounting beam when only the top is fixed, thus improving the quality of the cabinet.

[0046] Example 5

[0047] Based on Example 4, as shown in the appendix Figure 3 and attached Figure 4 As shown, in this embodiment, a reinforcing bracket 8 is also provided inside the mounting beam 7, and the fixing bolts 5 and high-strength bolts 6 used to fix the receiving chamber 1 are threaded through the reinforcing bracket 8. This design increases the structural strength of the mounting beam at the lifting device.

[0048] Example 6

[0049] Based on Embodiment 4 or Embodiment 5, this embodiment further includes a washer 9 fitted on the high-strength bolt 6 between the receiving chamber 1 and the mounting beam 7 or reinforcing bracket 8 to increase the structural stability of the receiving chamber.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
