Description
Technical Field
The invention relates to the technical field of indoor storage devices, in particular to a wall-mounted lifting storage rack.
Background
Garage, storeroom, family or office space generally need the supporter to place article, and the tradition is the console mode, for practicing thrift the interior space, and the back changes wall-hanging supporter or suspension type supporter into more, and both respectively have advantages, like wall-hanging lift supporter for suspension type supporter, it is relatively convenient to install, and the fastness of support will be better.
At present, wall-hanging lift supporter is of a great variety, and the structure is different, but prior art's wall-hanging lift supporter still has following not enoughly: some adopt single-upright-column support to put the lift of thing seat, put the bearing capacity of thing seat and receive the restriction, its equilibrium receives the influence when going up and down. Some adopt two stands to support the lift of putting the thing seat, but need two upper and lower connection diaphragm fixed, because the upper and lower both ends of every stand are all died by fixed the limit, have size and structural error in the actual motion a little, the noise appears very easily. And under the drive of the lifting drive mechanism, the outer pipe is sleeved on the inner pipe to be lifted by mutual friction, the bearing capacity and the mechanical property of the lifting drive mechanism are still not ideal, and the smoothness and the working stability and the reliability of the lifting process are not enough.
Disclosure of Invention
The invention aims to provide a wall-mounted lifting commodity shelf which is low in noise, good in mechanical property, smooth in lifting, stable and reliable.
The technical scheme of the invention is that the invention provides a wall-mounted lifting storage rack, which comprises a transverse fixing plate used for being fixed with a wall surface, wherein at least two guide rails which are also used as fixing upright posts are fixed on the transverse fixing plate; the lifting upright is positioned outside the guide rail, and a lifting part of the lifting upright is provided with a supporting rod for the object carrying plate.
After adopting the structure, the wall-mounted lifting shelf has the following advantages: because adopt two piece at least lift stand to drive and shelve the article lift on carrying the thing board bracing piece through carrying the thing board, the portion that goes up and down along the guide rail through supporting the rolling subassembly, carries the bearing capacity that the thing board or called cargo platform strong, and the equilibrium is good during the lift. Because the portion lower extreme that goes up and down does not have the transverse fixing plate fixed, goes up and down the portion lower extreme promptly for the free end and not died by fixed limit for the holistic installation of lift supporter is comparatively convenient, in the operation of actually going up and down, even size and structure slightly have the error, the noise also can not appear. Especially, the lifting part of the lifting upright post slides relative to the fixing part of the lifting part, and the lifting part also rolls along the guide rail by virtue of the supporting rolling component, so that the lifting upright post can offset some installation errors and manufacturing errors during operation, the noise is reduced, the bearing capacity is good, the mechanical property is strong, the area of the carrying platform can be greatly increased under the upright post structure with the same size, namely, objects with the same weight and volume are carried, and the material cost of the wall-mounted storage rack is relatively saved. In addition, after the structure is adopted, the lifting process of the wall-mounted storage rack is smooth, stable, reliable and efficient.
Furthermore, the guide rail is a first rectangular steel pipe, an opening which is communicated with the whole length of the guide rail is arranged in the middle of a front side plate of the first rectangular steel pipe, a connecting block for supporting the rolling assembly is fixed on a lifting part of the lifting upright post, such as an outer pipe described below, a shaft is arranged at the front end of the connecting block, which extends into the opening of the guide rail, and two first rolling bearings which are matched with a rear side plate of the first rectangular steel pipe in a rolling mode are arranged on the shaft.
