The present invention relates to the field of bed frame, and more particularly to a bed frame convenient for changing bed sheets.
In hotels, guesthouses and other accommodations, when changing the bed sheet, pull the bed out of the wall first, and then move the mattress to replace the bed sheet. Due to the large mass of the bed and the mattress, the pulling process is more laborious.
At present, the Chinese Patent Publication No. CN203815016U discloses a hotel bed with a slidable bed liner. It includes a bed frame with a backrest and a support liner arranged on the bed frame, wherein a sliding device is located between the support liner and the bed frame, and the sliding device is a drawer-type sliding device. The drawer-type sliding device includes a sliding track and a sliding unit that cooperates with the sliding track. The sliding track and the sliding unit, which are located above the bed frame and below the support liner, are fixedly connected with the bed frame and the support liner, respectively.
The bed liner of the above-mentioned hotel bed is able to be easily pulled out for facilitating changing the bed sheet, and however, while changing the bed sheet, the staff needs to walk around the bed liner to completely insert the bed sheet between the bed liner and the mattress, which makes the staff time-consuming and labor-intensive.
An object of the present invention is to provide a bed frame convenient for changing bed sheets, which has an advantage of changing the bed sheets easily.
To achieve the above object, the present invention provides technical solutions as follows.
A bed frame convenient for changing bed sheets comprises:
a base;
a rotation module for accommodating a mattress located above the base;
a sliding module located between the rotation module and the base;
a sliding device located between the sliding module and the base, wherein the sliding module is able to slide along a length of the base through the sliding device; and
a rotation device located between the sliding module and the rotation module, wherein the rotation module is able to rotate around a central axis of the sliding module through the rotation device.
Through the above technical solution, when a bed sheet needs to be changed, the sliding module and other elements above the sliding module are drawn out through the sliding device, and then the rotation module is driven to rotate through the rotation device, so that a staff is able to insert the bed sheet between the rotation module and the mattress without walking around the bed frame, which saves time and effort, is convenient and fast.
Preferably, the sliding device comprises a slide rail set on the base, a bottom surface of the sliding module is provided with a sliding block matched with the slide rail, the slide rail is arranged along the length of the base; there are at least two slide rails.
Through the above technical solution, the slide rail and the sliding block are matched not only with low friction resistance, but also the slide rail limits a sliding path of the sliding module, which prevent the sliding module from shifting the sliding path.
Preferably, the sliding device has a slide slot provided on the base, the bottom surface of the sliding module is provided with a sliding part which is able to be embedded and roll in the slide slot; the sliding part is a pulley or a universal ball; the slide slot is arranged along the length of the base; there are at least two slide slots.
Through the above technical solution, the sliding part rolls in the slide slot to drive the rotation module to slide, which is easy and convenient.
Preferably, the rotation device comprises a rotation assembly located between the sliding module and the rotation module, wherein the rotation module rotates through the rotation assembly.
Through the above technical solution, the rotation module rotates relatively to the sliding module through the rotation assembly, which is convenient for changing the bed sheets.
Preferably, the rotation assembly comprises a bearing seat located on the sliding module, the rotation module is provided with a rotation shaft rotatably connected with the bearing seat.
Through the above technical solution, the rotation shaft matches with the bearing seat, so that the rotation module is able to rotate relatively to the sliding module, which facilitates changing the bed sheets.
Preferably, the rotation assembly comprises a big rotation disk, wherein a top surface of the big rotation disk is fixedly connected with rotation module, a bottom surface of the big rotation disk is fixedly connected with the sliding module.
Through the above technical solution, the rotation module is able to rotate relatively to the sliding module through the big rotation disk, which facilitates changing the bed sheets.
Preferably, the rotation assembly comprises a small rotation disk, a top surface of the small rotation disk is fixedly connected with the rotation module, a bottom surface of the small rotation disk is fixedly connected with the sliding module, the sliding module is provided with multiple rotating parts evenly arranged around the small rotation disk, the rotating parts are universal balls or universal wheels.
Through the above technical solution, the rotating parts are able to expand a rotating area and reduce a size of the small rotation disk, thereby saving materials.
Preferably, the base is provided with two limiting parts, the two limiting parts are located at an initial position and an end position of the sliding module, respectively.
Through the above technical solution, when the sliding module is located at the initial position, the rotation module is avoided sliding; when the sliding module is located at the end position, it is convenient for the staff to rotate the rotation module.
Preferably, the sliding module is provided with two positioning parts symmetrically arranged with respect to the small rotation disk, a bottom surface of the rotation module is provided with positioning slots respectively matched with the positioning parts, and a connection line of the two positioning parts is perpendicular to a sliding direction of the sliding module.
Through the above technical solution, when the rotation module rotates by 180 degrees, the rotation module and the sliding module are relatively fixed to prevent the rotation module from shaking.
In summary, the present invention has some beneficial effects as follows.
(1) Through the cooperation of the sliding device and the rotation device, the staff is able to change the bed sheet only by standing in one position, which greatly saves energy and time of the staff.
(2) After changing the bed sheet every time, the mattress is rotated exactly 180 degrees, which is able to extend the life of the mattress.
