Description

Technical Field

[0001] This utility model relates to the field of folding bed technology, and in particular to a two-fold four-wheeled bed that is easy to fold. Background Technology

[0002] Four-wheeled beds have applications in many fields such as medical care, elderly care, home care, and outdoor recreation. Their advantages are reflected in their ease of movement, flexible use, improved care efficiency, and increased comfort and convenience. The design of the two-fold four-wheeled bed, which is easy to fold, is based on considerations such as saving space, enhancing the flexibility of use, and facilitating cleaning and maintenance.

[0003] A convenient folding two-fold four-wheeled bed generally consists of a bed frame, a bed surface, folding structural components, wheels, and wheel frames. The convenient folding two-fold four-wheeled bed achieves folding through specific folding structural components, relies on the wheels and wheel frames for movement, and is supported by the bed frame, bed board, and other components working together. Under these principles, the various components cooperate with each other to ensure its normal use.

[0004] Existing two-fold four-wheeled beds that are designed for easy folding cannot prevent the bed from automatically folding due to the weight of the user. When a user lies on the bed, the bed folds automatically due to the weight, which disrupts the bed's original stable support structure and causes a sharp shift in the center of gravity. This can easily lead to the bed tilting to one side, causing the user to fall off and suffer abrasions, falls, or even more serious injuries. This risk is particularly high for the elderly, the disabled, and those with injuries or illnesses. After such automatic folding occurs, users will be hesitant to use the four-wheeled bed again, always worried that the bed will fold unexpectedly again. This greatly reduces user trust in the product and affects their willingness to use it normally. Therefore, we propose a two-fold four-wheeled bed that is easy to fold to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a convenient two-fold four-wheeled bed, which aims to improve the problem that existing four-wheeled beds cannot avoid automatic folding due to human weight.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A convenient folding two-fold four-wheeled bed includes two bed frames, each of which is rotatably connected to a rotating bracket at its distal end. A connecting plate is rotatably connected to the outer side of the rotating bracket, and a rotating plate is rotatably connected to the inner side of the bed frame. An anti-folding component is rotatably connected to the inside of the bed frame.

[0008] Furthermore, the convenient folding two-fold four-wheel bed has a clever structural design, which includes two opposing bed frames. The far end of the bed frame is rotatably connected to the rotating bracket. The outer side of the rotating bracket is connected to the connecting plate through the rotating connection point, and the inner side of the bed frame is connected to the rotating plate. Inside the bed frame, there is also a prevention component consisting of a limiting rod, a limiting plate, and an elastic reset device, which can limit the rotation of related parts, ensuring stability when unfolded and convenience when folded, and meeting the needs of portability, practicality and multiple uses.

[0009] The prevention component includes a limiting plate, one side of which is rotatably connected to the inside of the bed frame, and a slot is provided on the side of the limiting plate away from the bed frame;

[0010] Furthermore, the limiting plate in the prevention component is crucial to the structural stability of the two-fold four-wheel bed that is easy to fold. One side is connected to the inside of the bed frame through a finely crafted rotating connection structure, which is flexible and reliable. The slot design on the other side is ingenious, with shape, size and depth adapted to the relevant components. The edges are polished and the inside is treated to enhance the stability of the fit, which helps the bed to operate in an orderly manner as expected, ensuring stability and convenience.

[0011] A limiting rod is rotatably connected inside the connecting plate, and the outer side of the limiting rod is rotatably connected inside the rotating plate.

[0012] Furthermore, the limiting rod plays an important role in the foldable two-fold four-wheel bed structure system. It is connected to the inside of the connecting plate through a carefully designed and high-precision rotating connection method, which can rotate stably and flexibly. The outer side and the inside of the rotating plate also have a matching connection structure. The two form a linkage relationship and jointly control the folding and unfolding of the bed, ensuring that it is stable when unfolded and smooth when folded, reflecting the scientific and practical nature of the structural design.

[0013] The outer side of the limiting rod is connected to the inside of the slot, and the outer side of the limiting plate is slidably connected to the outer side of the connecting plate;

[0014] Furthermore, the connection between the outer side of the limiting rod and the inside of the slot is a key and ingenious feature of the two-fold four-wheel bed structure that facilitates folding. The slot is customized according to the limiting rod, with fine machining of the inner wall and auxiliary structures to enhance stability and ensure the stability of the bed. The sliding connection between the outer side of the limiting plate and the outer side of the connecting plate is carefully planned, with high precision and special treatment of the contact surface. During operation, it slides according to the matching mechanism, which helps the bed to fold and unfold in an orderly manner, improving the structural flexibility and practicality.

[0015] As a further description of the above technical solution:

[0016] A mattress is slidably connected to the top of the bed frame, and a connecting bracket is rotatably connected to the adjacent ends of the two bed frames.

[0017] Furthermore, the sliding connection between the top of the bed frame and the mattress takes into account many factors, with finely machined tracks or grooves and optimized measures to ensure smooth mattress sliding and good positioning. The mattress is also designed to fit the design to ensure performance. The connecting bracket at the end of the two bed frames plays a key role. The rotating connection structure is flexible and stable. Its shape and size are determined according to the state of the bed frame. When unfolded, it fixes the bed frame to maintain stability. When folded, it works in coordination, reflecting the scientific and rational design of the structure and meeting various usage needs.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, a limiting plate works in conjunction with a limiting rod, which in turn works in conjunction with a connecting plate and a rotating plate. The connecting plate then works in conjunction with a rotating bracket. This prevents the connecting plate and rotating plate from folding when the four-wheeled bed is in use. When the bed bears the weight of a person, the force is transmitted and distributed reasonably along each component. When the connecting plate and rotating plate are restricted from folding, they can work in conjunction with the rotating bracket and other components at a pre-designed angle and position to evenly distribute the force to the bed frame and other related structures. This prevents excessive local stress, avoids damage to components due to unreasonable stress, and extends the overall service life of the bed. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a convenient folding two-fold four-wheeled bed, including two bed frames 1. The two bed frames 1 form the basic frame of the bed, which cooperate with each other to bear weight and connect forces, ensuring the stability and reliability of the bed and providing support for the user. Each of the two bed frames 1 has a connecting bracket 2 rotatably connected to one end of each other. The connecting bracket 2 is rotatably connected to the bed frame 1, which can tightly connect the two bed frames 1 when unfolded, prevent displacement, maintain the integrity and stability of the bed, and ensure safe use.

[0028] A mattress 8 is slidably connected to the top of the bed frame 1. The top of the bed frame 1 has a reasonable track that is adapted to the sliding of the mattress 8, which can limit the movement and ensure smooth sliding. The mattress 8 fits in with the track, and the user can push the mattress 8 to adjust its position with a little force, which is convenient for daily use and cleaning. The two bed frames 1 are rotatably connected to the far end of each other with a rotating bracket 3. After the rotating bracket 3 is connected to the bed frame 1, it can rotate flexibly. The angle range is suitable for folding and unfolding needs. It plays a connecting role in the changes of the bed structure and ensures that all parts move in an orderly manner.

[0029] The outer side of the rotating bracket 3 is rotatably connected to the connecting plate 4. The connecting plate 4 and the rotating bracket 3 are rotatably connected smoothly and tightly. When the bed is folded and unfolded, it transmits force and adjusts the position, and coordinates with each component to complete the shape transformation. The inner side of the connecting plate 4 is rotatably connected to the limiting rod 5. The limiting rod 5 rotates flexibly and has stable performance within the connecting plate 4. It is the key link connecting each component and controls the structural changes when the bed is folded and unfolded.

[0030] The inner side of the bed frame 1 is rotatably connected to a rotating plate 6. The rotating plate 6 is reasonably connected to the bed frame 1 and can rotate. Its size and other factors are determined by multiple factors. It can reliably bear force and cooperate with other components to complete the folding and unfolding of the bed. The outer side of the limiting rod 5 is rotatably connected to the inside of the rotating plate 6. The two form a linkage relationship, cooperate and restrict each other, and accurately control the folding and unfolding of the bed, ensuring that the movement of the components is orderly and accurate.

[0031] Reference Figures 2 to 4 The bed frame 1 has an internal rotating connection with a folding prevention component. The folding prevention component is crucial for maintaining stability in the unfolded state and preventing accidental folding. The folding prevention component includes a limiting plate 7. The outer side of the limiting plate 7 is slidably connected to the outer side of the connecting plate 4. The contact surfaces of the two are carefully designed to ensure smooth sliding and to coordinate the relative movement of the components, ensuring orderly operation.

[0032] One side of the limiting plate 7 is rotatably connected to the inside of the bed frame 1. The connection is firm and the rotation is flexible. It participates in controlling the folding state of the bed to ensure that it meets the usage requirements. The side of the limiting plate 7 away from the bed frame 1 has a slot. The slot is designed to adapt to the relevant components. The size and depth are reasonable and the engagement is firm, maintaining the stability of the bed when unfolded and ensuring reliable support for the user. The outer side of the limiting rod 5 is connected to the inside of the slot. The slot and the limiting rod 5 are adapted to each other and the connection is tight and firm. There are also auxiliary structures to enhance reliability and ensure the stability of the bed structure.

[0033] Working principle: When the operator needs to move the four-wheeled bed, they can rotate the limiting plate 7, causing it to move away from the outside of the limiting rod 5. The outside of the limiting rod 5 is connected to the connecting plate 4 and the rotating plate 6. After the limiting plate 7 moves away from the outside of the limiting rod 5, the connecting plate 4 and the rotating plate 6 can be folded. The other side of the connecting plate 4 is connected to the outside of the rotating bracket 3, and the other side of the rotating plate 6 is connected to the inside of the bed frame 1. Under normal circumstances, the connecting plate 4 and the rotating plate 6 are restricted by the limiting plate 7 through the limiting rod 5, ensuring an inclined straight line, thereby fixing the rotating bracket 3. When the limiting plate 7 moves away from the outside of the limiting rod 5, the connecting plate 4 and the rotating plate 6 can be folded. Once the restrictions are lifted, the connecting plate 4 and the rotating plate 6 can be folded. After the connecting plate 4 and the rotating plate 6 are folded, the rotating plate 3 will be driven by one end of the connecting plate 4 connected to the outside of the rotating bracket 3, so that the rotating bracket 3 is stored inside the bed frame 1. After processing all four corners in this way, the two bed frames 1 can be folded in half. The two bed frames 1 are connected to the adjacent ends of the two bed frames 1. The two bed frames 1 are connected together after being folded by the connecting bracket 2. The two bed frames 1 are connected to one side of each bed frame 1. The folded bed frame 1 can then be moved by the wheels.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
