Description

Technical Field

[0001] This utility model relates to a bed, specifically a modular trolley bed. Background Technology

[0002] Beds are an essential piece of furniture in people's daily lives. Existing beds have complex and poorly designed structures, employing a fixed, one-piece design that cannot be modified to meet the user's specific needs. Some users desire to expand their usable space in certain situations and fold away to reduce floor space when not in use, a feature that current bed structures cannot provide. Furthermore, existing bed frames utilize a wide variety of materials, requiring the processing of numerous types of boards in the factory before assembly, which reduces on-site assembly efficiency, increases costs, and hinders large-scale production. Therefore, the inventor has improved the bed frame structure. Utility Model Content

[0003] The purpose of this utility model is to provide a modular trolley bed, which has the advantages of simple structure, reasonable design, fewer types of boards, low processing cost, modular design of both the bed frame and the movable frame, which facilitates assembly, reduces costs, improves on-site assembly efficiency, can meet the needs of large-scale production, and its form can be changed according to user needs to adapt to different usage scenarios, thus solving the problems mentioned in the above technical background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular trolley bed, comprising a bed frame and a movable frame mounted on the bed frame. The bed frame includes two parallel side supports, and multiple vertically arranged rear side panels are disposed between the two side supports. Each rear side panel is fixed at both ends to the two side supports. Adjacent rear side panels are connected by connecting beams. A horizontally arranged main platform is fixed to one of the rear side panels. Therefore, the overall structure of the bed frame consists of two side supports, multiple rear side panels, and a main platform. With fewer types, the processing cost is lower. The movable frame includes horizontally arranged platform beams, multiple platform beams are stacked vertically and can slide horizontally. The top platform beam is fixedly connected to the main platform, and the remaining platform beams are all located below the top platform beam and can slide horizontally to achieve an unfolding or retracting effect, so that the remaining platform beams are all retracted below the first platform beam. The principle of the retraction or unfolding of multiple platform beams is the same as the principle of drawer movement in the prior art. The bottom platform beam has a pull-out plate fixed at the end away from the main platform.

[0005] Preferably, a first strip-shaped positioning groove is provided at both ends of the connecting beam, and the rear side plates at both ends of the connecting beam are respectively inserted into the two first strip-shaped positioning grooves and fixed to both ends of the connecting beam.

[0006] Preferably, two second strip-shaped positioning grooves are provided at one end of the main platform near the rear side plate. The two second strip-shaped positioning grooves are distributed on the upper and lower end faces of the main platform. Rear side plates are provided at both ends of the main platform. The two rear side plates are respectively inserted into the two second strip-shaped positioning grooves and fixed to the main platform. In this way, the main platform and the two rear side plates are more tightly connected, ensuring the stability of the main platform.

[0007] Preferably, a fixed cover plate is also fixed between the two side supports. The fixed cover plate is located above multiple rear side plates, and a movable cover plate is connected to the fixed cover plate by a hinge. The movable cover plate can be flipped along the hinge and stacked on the fixed cover plate to make the top of the bed frame more open. Alternatively, the movable cover plate can be flipped to the same height as the fixed cover plate and pressed on the two side supports to make the top of the bed frame more sealed, so as to meet the needs of different users.

[0008] Preferably, a reinforcing plate is fixed at the end of each of the two side supports that are close to each other, and a sealing plate is fixed at the end of each of the two reinforcing plates that is close to the pull-out plate.

[0009] Preferably, the length of the multiple platform beams gradually decreases from left to right, and each platform beam has side baffles fixed at both ends, so that the multiple platform beams can be stored together by pulling them out.

[0010] Preferably, a bottom cover is fixed at the end of the pull-out plate away from the platform beam plate, and two top covers are provided above the bottom cover. The two top covers are fixed as one piece, and an inner connecting plate is fixed at the end of each top cover near the main platform plate. The two inner connecting plates are respectively fixed between the two side supports.

[0011] Preferably, it also includes two sets of rollers, which are respectively located at the bottom of the bed frame and the movable frame, and are respectively installed at the bottom of the two side supports and the bottom of multiple side baffles, with multiple rollers in each set.

[0013] 1. This utility model provides a modular trolley bed, which includes a bed frame and a movable frame mounted on the bed frame. The overall structure is simple and reasonably designed. The bed frame includes two parallel side supports, and multiple vertically placed rear side panels are arranged between the two side supports. Both ends of each rear side panel are fixed to the two side supports. Adjacent rear side panels are connected by connecting beams. A horizontally arranged main platform is fixed on one of the rear side panels. Therefore, the overall structure of the bed frame consists of two side supports, multiple rear side panels, and a main platform. The types of materials are relatively few, so the processing cost is low. Both the bed frame and the movable frame adopt a modular design, which facilitates assembly, reduces costs, improves on-site assembly efficiency, and can meet the needs of large-scale production. It is suitable for widespread use.

[0014] 2. The movable frame in this utility model includes horizontally arranged platform beams. Multiple platform beams are stacked vertically and can slide horizontally. The top platform beam is fixedly connected to the main platform. The remaining platform beams are all located below the top platform beam and can slide horizontally to achieve an unfolding or retracting effect, so that the remaining platform beams are all retracted below the first platform beam. The bottom platform beam has a pull-out plate fixed to the end away from the main platform. When in use, the movable frame can be pulled out from the inside of the bed frame to extend the overall length and obtain more usable space. When not in use, it can be retracted into the inside of the bed frame to reduce the footprint. The shape can be changed according to user needs to adapt to different usage scenarios and meet various needs, making it highly practical. Attached Figure Description
