Description
Technical Field
The invention relates to a mechanical attic, in particular to a mechanical attic device with a folding and opening cover plate.
Background
At present, most of attics of buildings are integral attics structures fixed together with the buildings, and the attics structures need to occupy larger space and are generally only arranged on the top layer; and under the condition that the living space is small, the attic cannot be arranged.
With the rise of house prices, the rational application of building space has become a consideration for many households and businesses. Therefore, many folding furniture and the like are also introduced in the market, and the products generally adopt hidden moving modes such as hanging, folding and the like to obtain local space, but the high space of the house is difficult to be fully utilized. For the current common high small-area shops, the area of the shop is small, so that the method of separating the space in the height direction by the sectional material is high in cost, and the window is easily shielded after the interlayer, so that the daylighting rate is reduced, and the lower-layer shop is dark. Due to the reasons, the interlayer is not usually arranged in the conventional high-small-area shops, so that the high-high space is wasted.
Research and development find that the idea of reasonably utilizing the height space of the high small-area shops of the merchants exists, and only no reasonable solution is provided for the merchants to select at present. Merchants are mostly in the contradiction of wanting to maintain the openness of shops and having rest space after being idle. The mechanical attic is a feasible scheme capable of effectively utilizing the height space of a house, an upper attic is added by adding an interlayer in a floor, the upper attic can be used as a horizontal type and the like, the actual use area of the house is increased, and the mechanical attic can also be used in a small-area raising shop. However, most of the existing mechanical attics adopt a lifting structure, and when the attics on the upper floor are not used, the attics on the lower floor are lifted upwards so as to ensure the height of the space on the lower floor and the daylighting property. For example, the name disclosed in chinese patent No. ZL201620280986.7 is "an intelligent mobile attic", the name disclosed in chinese patent application No. 201910426981.9 is "a lifting attic using two lifting columns", and the name disclosed in chinese patent application No. 202010285166.8 is "a household lifting attic", and the like, these lifting attic structures can expand the use space of houses and shops, but for high small-area shops, the lifting attic needs to be lifted by a large stroke to give a window a daylighting property, which has high requirements for the manufacturing and assembling precision of the lifting attic, and the complicated lifting transmission structure also brings more failure rates, and the manufacturing cost is relatively high, so that the elevating attic is difficult to be favored by merchants.
Based on the above problems existing in the practical application process of the existing lifting attic, a novel mechanical attic needs to be designed.
