The two main frame bodies can be folded into a compact state for convenient placement and storage inside vehicles of various specifications, and can be used for various purposes and occasions depending on actually demands of users, e.g. a dining table, a chair or a bed for outdoor traveling, excursion, camping, or other leisure activities. Accordingly, the present invention can be selectively used on the ground or inside a vehicle in different time, occasions and locations to show its multiple functions and practical efficiency.

Description

Multifunctional lathe frame structure

The present invention relates to a multifunctional lathe frame structure, and in particular, to a multifunctional lathe frame structure that can be folded and assembled according to needs, and is its inventor and application.

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 existing folding bed still has a large volume after folding, and on the other hand, the adjustable range of its expanded size is very small. Therefore, it is necessary to design a folding bed that is small in size after folding and can be flexibly adjusted in length, width and height after unfolding.

Therefore, there is a portable folding bed frame like Chinese Patent No. CN216256356U, which is characterized in that it includes a left frame and a right frame. The overall structures of the left frame and the right frame are both rectangular, and the outer sides of the left frame and the right frame are connected by two sets of hinges. Rotation connection, the rotation angle of the hinge is 0~180 degrees, the structure of the left frame and the right frame are symmetrically arranged, there are bed leg connection seats at the four corners of the left frame and the right frame, the openings face the inside when folded and stored. , both the left frame and the right frame can be retracted along the length and width of the bed frame. The disadvantage is that the bed legs cannot be inserted in the stored state. In the stored state, it is impossible to assemble a mobile kitchen or a table with large or small table tops, that is, it cannot be assembled and constructed. Tables, beach beds, mobile medical beds, etc. change usage status.

Or Chinese Patent No. CN210095212U, a folding bed for sleeping on the stomach, which includes a bed frame. The bed frame is provided with a first bed frame and a second bed frame. The front end of the first bed frame is provided with a telescopic The head and face support can be adjusted to suit the user's face shape, so that when the user is lying prone, the eyes, nose, and mouth can be suspended in the air without being compressed, keeping the respiratory tract open. There is also a can be placed directly below the two horizontal bars. The foldable movable tabletop can be used for reading; the frame of the first bed is also equipped with two parallel vertical poles that support both sides of the chest and abdomen, which can be adjusted according to the user's body shape and can suspend the front of the chest and abdomen so that they are not compressed. In addition to being used as a hospital operating bed for back surgery, a hospital bed, and a general household bed, the folding bed can also be used separately as a household bed and table top, 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 stored state, it is impossible to assemble mobile kitchens and tables with large and small desktops, that is, it cannot assemble tables, chairs, beach beds, and mobile medical treatments. Changes in usage of beds, etc.

Although the above-mentioned folding bed structure can provide the convenience of being foldable and reducing the size, its range of use is limited to a bed set that can be used by a single person. However, in addition to sleeping at night, outdoor camping activities also need to prepare equipment such as resting, enjoying the scenery, or cooking. However, such a large number of equipment cannot be accommodated in vehicles of different types and specifications. Therefore, R&D has a small A folding bed that is both compact and multi-functional has become one of the most important issues.
