Description

Double-layer iron frame bed based on lifting bed curtain and using method thereof

Technical Field

The invention relates to the technical field of iron frame beds, in particular to a double-layer iron frame bed based on a lifting bed curtain and a using method thereof.

Background

The iron frame bed is also called as a bunk bed or an apartment bed or a bunk bed, is derived from a bunk bed of a wood frame, and is characterized in that: the iron frame bed is convenient to detach and install, high in stability, capable of effectively utilizing vertical space and greatly increasing space capacity, and can be widely applied to dormitories of various groups.

Nowadays, the privacy concept of people is gradually deepened, the number of people is more when the people are in a dormitory, the private space is less, and a bed curtain is needed to manufacture some private spaces for individuals. Most of the existing iron frame bed curtains adopt a single form of opening or rolling towards two sides, so that the bed curtains can not be freely selected and changed and can not meet the use habits of different users. Based on this, this scheme provides one kind and can enough roll-up can stir the iron stand bed of bed curtain again.

Disclosure of Invention

In view of the disadvantages of the prior art, a first object of the present invention is to provide a double-layer iron frame bed based on a lifting bed curtain, which has the advantage that the opening and closing modes of the bed curtain can be switched by pulling different driving chains.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a double-deck iron stand bed based on lift bed curtain, the bed body, the inside fixedly connected with elevating gear of the bed body, elevating gear is including installation casing, roll-up portion, dials curtain portion and sticking department, installation casing level sets up the inside at the bed body, roll-up portion rotates with one side of installation casing inside to be connected, dial curtain portion and the inside lower extreme sliding connection of installation casing, the sticking department sets up in roll-up portion and one side of dialling curtain portion, roll-up portion includes roll-up axle and first drive chain, roll-up axle and the inside sliding connection of installation casing, first drive chain meshes with the one end of roll-up axle mutually, the fixed surface of roll-up axle installs the bed curtain.

By adopting the technical scheme, the bed curtain is in a shielding state in an initial state, and when the first driving chain is pulled, the furling shaft rotates to furl the bed curtain, so that the lifting control of the bed curtain is realized; simultaneously when the bed curtain is in shielding state, the pulling is dialled curtain portion and can is extrudeed the upper portion of bed curtain, make the bed curtain pull open to both sides, thereby realize opening and closing the bed curtain, the design of locking part makes the bed curtain just can select to go up and down or open when shielding state, will lock another function after selecting one of them, in order to avoid the bed curtain when dialling curtain portion open mode, the roll-up axle rolls up the bed curtain, the roll-up axle is drawn into too much bed curtain and is caused local too much, local frictional force is great, be unfavorable for the normal decline of bed curtain when releasing, up to this moment can realize the roll-up to the bed curtain, open and close.

The invention is further configured to: the curtain poking part comprises a driving shaft, a second driving chain and a rotating set, the driving shaft is rotatably connected with one side of the inside of the mounting shell, the second driving chain is in sliding connection with the inside of one side of the driving shaft, one end of the driving shaft is meshed with the second driving chain, and the upper part of the rotating set is meshed with the other side of the driving shaft.

Through adopting above-mentioned technical scheme, accessible pulling second drive chain drive driving shaft rotates, through engagement structure with power transmission to the rotating group, accomplishes power transmission.

The double-layer iron frame bed based on the lifting bed curtain as claimed in claim 5, characterized in that: one end of the first clamping block (502) facing the second clamping block (503) is integrally formed with a limiting column, and one end of the second clamping block (503) facing the first clamping block (502) is provided with a butt joint groove corresponding to the limiting column.

8. The double-layer hob bed based on the lifting bed curtain as claimed in claim 5, characterized in that: the top ends of the first locking block (505) and the second locking block (506) are both fixed with an elastic reset piece (7), and the elastic reset piece (7) is fixedly connected with the inside of the mounting shell (201).

9. The double-layer iron frame bed based on the lifting bed curtain as claimed in claim 5, characterized in that: the equal integrated into one piece in bottom of first locking piece (505) and second locking piece (506) has the locking post, the locking groove with locking post matched with has all been seted up on the top of first screens piece (502) and second screens piece (503).

10. A use method of a double-layer iron stand bed based on a lifting bed curtain is applied to the double-layer iron stand bed based on the lifting bed curtain, which is disclosed by any one of claims 1-9, and is characterized in that: the method comprises the following steps:

step 1: in the initial state, the bed curtain (6) is in a closed state;

and 2, step: the bed curtain (6) is furled, the first driving chain (302) is pulled downwards, meanwhile, the locking part (5) moves downwards and locks the second driving chain (402), and meanwhile, the furling shaft (301) is driven to rotate, so that the bed curtain (6) is furled;

and step 3: when the furled bed curtain (6) is released, the first driving chain (302) is pulled to jack up the locking part (5) upwards, the locking of the second driving chain (402) is released, and the release of the bed curtain (6) is completed;

and 4, step 4: the bed curtain (6) is opened, the second driving chain (402) is pulled downwards, meanwhile, the locking part (5) moves downwards and locks the first driving chain (302), and the curtain poking part (4) is driven to move, so that the operation of opening the bed curtain (6) is realized;

and 5: the bed curtain (6) is closed, the second driving chain (402) is pulled, the locking part (5) is jacked upwards to release the limitation on the first driving chain (302), and the curtain poking part (4) is driven to move reversely, so that the bed curtain (6) is gradually closed.
