Detailed Implementation

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This embodiment provides a storage cabinet, which is a specific application of a suspended structure. The storage cabinet can be a refrigerator. Figure 1 As shown, the storage cabinet includes a suspension structure, a cabinet body 100, and a cabinet door 200. The suspension structure includes a lower base 300 and a lifting member 400 that can move up and down relative to the lower base 300. The lower base 300 is provided with a support platform 311 and a limiting groove 312. The lifting member 400 has a limiting part 411. The lifting member 400 is rotatably arranged relative to the lower base 300 so that the limiting part 411 abuts against the upper end of the support platform 311 or is embedded in the limiting groove 312. A return drive member 500 is provided between the lower base 300 and the lifting member 400. The return drive member 500 is a steel wire. In other optional embodiments, the return drive member 500 can also be a torsion spring or a reset device.

[0027] When the cabinet door 200 is closed, the limiting part 411 abuts against the support platform 311, and the lifting component 400 is in a high position. When the cabinet door 200 is opened to the first angle, for example, to 90 degrees, the limiting part 411 and the support platform 311 are misaligned, and the lifting component 400 descends under the action of gravity, causing the limiting part 411 to fall into the limiting groove 312. The force required for the lifting component 400 to rise is greater than the torque of the return drive component 500, so the cabinet door 200 can be suspended at the first angle.

[0028] In this embodiment, the lower seat 300 is fixed to the housing 100, and the lifting component 400 is fixed to the cabinet door 200. Figure 1As shown, the hovering structure is installed at the lower right corner of the storage cabinet. The lifting piece 400 is fixed on the cabinet door 200, and in this embodiment, it is completely fixed, that is, the lifting piece 400 cannot move or rotate relative to the cabinet door 200 in various directions, so that the lifting piece 400 needs to overcome the gravity of the cabinet door 200 when it is lifted, thereby improving the stability of the hovering of the cabinet door 200. In other alternative embodiments, the lifting piece 400 can be fixed on the cabinet door 200, and can only be circumferentially fixed, so that the cabinet door 200 can drive the lifting piece 400 to rotate, but the lifting piece 400 can be lifted relative to the cabinet door 200. In other alternative embodiments, the lower seat 300 can also be fixed on the cabinet door 200, and the lifting piece 400 is fixed on the box body 100. At this time, the hovering structure can be installed at the upper end of the storage cabinet, for example, at the upper right corner.

[0029] As shown in Figure 3 , 4 , 6, 7, the support table 311 and the limiting part 411 have a guide structure thereon. When the lifting piece 400 rotates relative to the lower seat 300 in a first direction, the guide structure moves the lifting piece 400 upward relative to the lower seat 300, and the limiting part 411 moves from the limiting groove 312 to the upper end of the support table 311. The guide structure is a guide slope 313. The guide structure ensures that the limiting part 411 can be smoothly moved from the limiting groove 312 to the upper end of the support table 311. In this way, whether the cabinet door 200 is opened or closed, it can be achieved by pushing the cabinet door 200 with one hand, which is relatively convenient to operate, and is not prone to cause the cabinet door 200 to be not smooth to open and close due to bending of components, which is conducive to the cabinet door 200 to be kept smooth to open and close for a long time. In other alternative embodiments, the guide structure can be provided only on the support table 311 or the limiting part 411. In other alternative embodiments, the support table 311 and the limiting part 411 can also not have a guide structure, and the lifting piece 400 is circumferentially fixed relative to the cabinet door 200, and the lifting piece 400 can move up and down relative to the cabinet door 200, and the hovering limiting is released by manually rotating the lifting piece 400.

[0030] As shown in Figure 3 , 4 , 6, 7, a limiting structure is arranged between the lifting piece 400 and the lower seat 300 to limit the rotation angle of the lifting piece 400 relative to the lower seat 300. The function of the limiting structure is to limit the rotation angle of the lifting piece 400 relative to the lower seat 300, to prevent the cabinet door 200 from being opened too much, for example, to limit the maximum opening angle of the cabinet door 200 to 120 degrees, to ensure the stability of the cabinet door 200 within a certain angle, and to prevent accidental damage.

[0031] Further, the limiting structure comprises a first limiting wall 314 located at one end of the support table 311 and a second limiting wall 412 located at one end of the limiting part 411, the first limiting wall 314 and the second limiting part 411 abut to prevent the lifting piece 400 from rotating to the second direction relative to the lower seat 300. The first limiting wall 314 and the guide structure on the support table 311 are respectively located at both ends of the support table 311, and the second limiting wall 412 and the guide structure on the limiting part 411 are respectively located at both ends of the limiting part 411. In other alternative embodiments, the first limiting wall 314 can also be arranged separately from the support table 311, and the second limiting part 411 can also be arranged separately from the limiting part 411.

[0032] As shown in Figures 6-7 , the first limiting wall 314 and the second limiting wall 412 are vertical walls. An angle less than or equal to 5 degrees with a vertical plane can be regarded as a vertical wall, and such limiting effect is better. Of course, in other alternative embodiments, the angle of the first limiting wall 314 and the second limiting wall 412 relative to the vertical plane can also be greater than 5 degrees, as long as it can prevent the cabinet door 200 from being opened further.

[0033] As shown in Figures 5-7 , the lower seat 300 is provided with a mounting groove 315, the support table 311 is located in the mounting groove 315, the lifting piece 400 has a mounting column 413, the limiting part 411 is located on the mounting column 413, and the mounting column 413 is embedded in the mounting groove 315. The groove wall of the mounting groove 315 can form a transverse constraint on the lifting piece 400, so that the relative position of the lower seat 300 and the lifting piece 400 is more stable, and the lifting of the lifting piece 400 is also more stable.

[0034] As shown in Figure 2 , 3 , the lower seat 300 comprises a lower seat body 310 and a screw rod 320, a gear 330 and a torsion adjusting seat 340 mounted on the lower seat body 310, the support table 311 is located on the lower seat body 310, the gear 330 is fixedly connected in the circumferential direction relative to the torsion adjusting seat 340, the lower end of the steel wire is fixed on the torsion adjusting seat 340, the screw rod 320 and the gear 330 are engaged, rotating the screw rod 320 drives the gear 330, further drives the torsion adjusting seat 340, so that the steel wire is twisted, and the size of the torsion of the steel wire can be adjusted. The screw rod 320 and the torsion adjusting seat 340 are assembled on the lower seat body 310 through a fixed shell 350. The torsion adjusting seat 340 has a square hole 342, and the cross section of the steel wire is square, the steel wire is inserted into the square hole 342 to form a circumferential fixation.

[0035] As shown in Figure 8As shown, the torsion adjusting seat 340 has a polygonal prism 341, the gear 330 is sleeved on the polygonal prism 341, and the outer diameter of the polygonal prism 341 gradually increases from top to bottom. In this way, the installation of the gear 330 is facilitated. The lower seat 300 of the present embodiment is a component structure including multiple independent components, and in other alternative embodiments, the lower seat 300 can also be a one-piece.

[0036] Further, as shown in Figure 3 The lifting member 400 includes a reinforcing plate 420, an upper seat body 410 fixed on the reinforcing plate 420, and a sleeve 430 fixed on the upper seat body 410. The upper end of the steel wire is fixed on the sleeve 430, and the reinforcing plate 420 is fixed on the cabinet door 200. The lifting member 400 of the present embodiment is also a component structure including multiple components. In other alternative embodiments, the lifting member 400 can also be a one-piece. The upper seat body and the lower seat body are made of POM wear-resistant plastic, which can effectively reduce the noise of opening and closing the door, slow down the wear, and prolong the service life of the storage cabinet. In other alternative embodiments, the upper seat body and the lower seat body can also be made of metal materials such as stainless steel.
