Description

Multifunctional Lathe Frame Structure

This creation is about a multi-functional lathe frame structure, especially a multi-functional lathe frame structure that can be folded and assembled according to requirements.

Press, when doing outdoor activities, it is usually necessary to design the bed into a foldable state for easy portability. However, on the one hand, the volume of the existing folding bed is still large after being folded, and on the other hand, the adjustable range of its size after unfolding is very small. Therefore need to design a kind of folding bed that volume is small and exquisite after folding, length, width and height all can be adjusted flexibly after unfolding.

Therefore promptly have as Chinese patent CN216256356U number a kind of portable folding bed frame, it is characterized in that: comprise left frame and right frame, the integral structure of described left frame and right frame is rectangle, the outer side of left frame and right frame passes two groups of hinges Rotation connection, the rotation angle of the hinge is 0~180 degrees, the structures of the left frame and the right frame are symmetrically arranged, and the four corners of the left frame and the right frame are equipped with bed leg connecting seats, and the opening is corresponding to the inside when folded and stored. , the left frame and the right frame can be stretched along the length and width of the bed frame. The disadvantage is that the bed legs cannot be inserted in the storage state, and the mobile kitchen and the table with large and small desktops cannot be assembled in the storage state, that is, it cannot be assembled and constructed. Tables, beach beds, mobile medical beds, etc. change the use status.

Or Chinese patent CN210095212U No., a kind of foldable bed that can be used for lying down and sleeping, comprises a bed frame, and this bed frame is provided with a first bed frame and a second bed frame, and the front end of the first bed frame is provided with a retractable The head and face support can be adjusted to suit the user's face shape, so that the user's eyes, nose, and mouth can be suspended in the air without being oppressed, and the airway can be kept unobstructed. Foldable movable table top for reading; the frame of the first bed is also equipped with two parallel poles supporting both sides of the chest and abdomen, which can be adjusted according to the user's body shape, and can be suspended in front of the chest and abdomen to prevent it from being oppressed. The folding bed can be used as an operating bed for back surgery in the hospital, a hospital bed and a general household bed. Its accessories, the hollow sleeping pillow and the bending frame, can also be used separately for household beds and tabletops, making the folding bed multifunctional. The disadvantage is that only the first and second bed frames can be used as single beds when they are opened. In the storage state, mobile kitchens and tables with large and small desktops cannot be assembled, that is, tables, chairs, beach beds, and mobile medical cannot be assembled. Beds, etc. change usage status.

Although the above-mentioned folding bed structure can provide the convenience of being foldable and shrinking in size, the scope of use is limited to the range of beds that can be used by a single person. However, in addition to considering the problem of sleeping at night, outdoor camping activities also need to prepare equipment such as rest rides, viewing scenery or cooking, but so many equipment cannot be accommodated in vehicles of different types and specifications. Therefore, research and development have little It has become one of the most important issues to have a foldable bed with multiple functions at the same time.
