Detailed Description

The utility model is further illustrated by the following specific figures and examples.

The structure of the variable width large space elevator of the present embodiment is shown in fig. 1. The lifter is arranged in the hanging cabinet and is used for lifting a hanging basket 2 in the hanging cabinet. The cabinet comprises a cabinet basket 2 and a mounting housing 4, the mounting housing 4 being bolted at a first bolt hole 8 and a second bolt hole 9. Rear swing rods 1 and front swing rods 3 are mounted on two sides of a cabinet basket 2, the rear swing rods 1 and the front swing rods 3 are arranged in parallel, one ends of the rear swing rods 1 are hinged to the cabinet basket 2, the other ends of the rear swing rods 1 are hinged to an installation shell 4, one ends of the front swing rods 3 are hinged to the cabinet basket 2, and the other ends of the front swing rods 3 are hinged to the installation shell 4. The rear swing rod 1 and the front swing rod 3 can rotate along with the lifting of the cabinet basket 2. As shown in fig. 2, a hinge point B1 between the rear swing link 1 and the cabinet basket 2, a hinge point B between the rear swing link 1 and the installation casing 4, a hinge point C1 between the front swing link 3 and the cabinet basket 2, and a hinge point C between the front swing link 3 and the installation casing 4 together form a parallelogram mechanism. When the cabinet basket 2 is in the retracted state, the rear swing link 1 and the front swing link 3 are both inclined backwards.

In the present embodiment, as shown in fig. 2, a torsion bar 6 is installed between the hinge points of the rear swing link 1 and the installation case 4 on both sides of the cabinet basket 2, i.e., between the hinge points B on both sides, and both ends of the torsion bar 6 are installed at the hinge points B through torsion links 5. Specifically, at the hinge point of the rear swing link 1 and the mounting case 4 on both sides, the rear swing link 1 is synchronously hinged to the torsion-proof rod 6 through the torsion-proof connector 5, the torsion-proof connector 5 is fixedly mounted on the hinge point of the rear swing link 1 and the mounting case 4, and further preferably, the torsion-proof connector 5 is fixed on the hinge point of the rear swing link 1 and the mounting case 4 through a screw. The torsion-proof rod 6 is fixedly connected with the torsion-proof connecting piece 5 through an inserting structure. The torsion-proof bar 6 is tightly attached to the lower part of the cabinet basket 2, thereby increasing the lower space of the lower cabinet basket 2. When the cabinet basket 2 is in the withdrawing state, the torsion-proof rod 6 is positioned below the cabinet basket 2, and when the cabinet basket 2 is in the pulling-out state, the torsion-proof rod 6 is positioned behind the cabinet basket 2. At present cabinet basket bottom, the handle rear is prevented turning round the pole and is blockked, can't place the storage article, has wasted the valuable cabinet in and has received the space. After the width-variable large-space elevator is adopted, the anti-torsion bar can be effectively prevented from colliding with other components (such as a handle) in the cabinet basket, an article containing space below the anti-torsion bar of the cabinet basket is formed, namely, a layer of storage space is added, and meanwhile, the anti-torsion bar does not occupy the original containing space, so that the extremely-sensitive application of the space in the cabinet can be realized.

One preferable structure of the insertion structure in this embodiment is as shown in fig. 4 and 5, the torsion-proof bar 6 is configured to have a hollow structure with a polygonal cross section (specifically, a regular hexagonal structure in this embodiment), the regular hexagonal convex column 5-1 matched with the regular hexagonal hollow structure of the torsion-proof bar 6 is disposed on the torsion-proof connector 5, and the regular hexagonal convex column 5-1 of the torsion-proof connector 5 can be inserted into the regular hexagonal hollow structure of the torsion-proof bar 6, so that the torsion-proof bar 6 is fixed on the torsion-proof connector 5. The regular hexagon convex column 5-1 of the torsion-proof connecting piece 5 can be inserted into the regular hexagon hollow structure of the torsion-proof bar 6 to form the insertion structure. The anti-twist connecting piece 5 is arranged at the hinged rotating point of the rear swing rod 1, so that the rear swing rods on two sides synchronously rotate in the lifting process of the cabinet basket 2.

In order to prevent the mutual play of the plugging structures, the embodiment also leaves first pin holes 6-1 at both ends of the torsion-proof bar 6, as shown in fig. 5. Meanwhile, a second pin hole 5-2 is formed in the outer edge of the regular hexagonal boss 5-1, as shown in fig. 4. After the torsion-proof bar 6 is arranged on the regular hexagon convex column 5-1, the positions of the first pin hole 6-1 and the second pin hole 5-2 correspond, so that the torsion-proof bar 6 can be fixedly connected with the torsion-proof connecting piece 5 into a whole through a pin or a screw.

As shown in fig. 7, the front swing rods 3 on both sides are mounted on the mounting case 4 via the front swing link mechanism 7. In this embodiment, a specific preferred structure of the pendulum connection mechanism 7 is shown in fig. 7, and includes a nut sleeve 3-1, a rotating sleeve 3-2, a gasket 3-3, and a fastening nail 3-4. The nut sleeve 3-1 is fixed in a hinge hole between the front swing rod 3 and the mounting shell 4, the rotating sleeve 3-2 is embedded in the mounting shell 4, the gasket 3-3 is mounted between the fastening nail 3-4 and the rotating sleeve 3-2, and the gasket 3-3 is not attached to the mounting shell 4. When the fastening nail 3-4 is locked and installed in the nut sleeve 3-1, the front swing rod 3 can be hinged on the installation shell 4.

In this embodiment, the cabinet basket 2 has a structure as shown in fig. 3, and includes side plates 2-1, a section bar 2-3 clamped between the side plates 2-1, a handle 2-2, and a bottom plate 2-4. The side plates 2-1, the section bars 2-3, the handles 2-2 and the bottom plates 2-4 are mutually locked to form an integral frame structure comprising a plurality of layers of containing spaces (the cabinet basket in the implementation comprises two layers of containing spaces). In the embodiment, the lengths of the side plates 2-1, the section bars 2-3, the handles 2-2, the bottom plates 2-4 and the torsion-proof rods 6 can be changed along with the change of the width of the cabinet basket, so that the cabinet basket is changed along with the change of the width of the cabinet body.

When the device is applied specifically, a user deduces the installation width of the large-space elevator with the customized width and the required widths of the section bars 2-3, the handles 2-2 and the bottom plates 2-4 in the cabinet basket 2 according to the width of the cabinet, and the customized production of the width can be completed on the premise that other production processes are the same.

When the large-space elevator is used specifically, the installation shell 4 is installed close to the bottom, as shown in fig. 6, when the cabinet basket 2 returns to the cabinet, an article storage space below the cabinet basket torsion-proof rod 6, a storage space on the lower layer of the cabinet basket 2 and a storage space on the upper layer of the cabinet basket 2 are formed, and the cabinet basket can form two layers or multiple layers of storage spaces according to requirements, so that the large-space elevator disclosed by the utility model has more storage spaces below the cabinet basket torsion-proof rod 6 than the existing elevator, and the article storage space in the cabinet is increased.

When the multifunctional electric cabinet is used specifically, a user pulls the handle 2-2 in the cabinet body basket 2 to pull out the cabinet body basket 2 from a high position and automatically and stably descend to a height which can be touched by a hand, so that articles can be taken conveniently, and the force adjusting buttons of the two side mounting shells 4 can be inserted and pulled out according to the weight of the articles, so that the weight of the pushing force is increased when the articles are stored, and the user use experience is enhanced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
