Abstract
Description
Technical Field
[0001] This utility model relates to the field of companion bed technology, and in particular to a portable folding companion bed. Background Technology
[0002] The companion bed is a foldable and portable bed designed specifically for hospital, nursing home and home care scenarios. Its main function is to provide temporary rest facilities for caregivers, while also taking into account practical needs such as saving space, easy movement and quick storage.
[0003] In hospitals, nursing homes, and home care settings, folding companion beds are widely used due to their space-saving and easy-to-store characteristics. Currently, most folding companion beds on the market use a simple hinge structure to achieve folding and storage, and are fixed by external components such as pins or buckles. However, in actual use, the locking of these companion beds after folding often relies on manual operation, which can easily lead to accidental unfolding during transportation due to forgetting or insecure locking. Furthermore, during unfolding, the bed lacks an effective buffer or segmented control mechanism, and often falls rapidly due to gravity, which not only generates noise but also easily injures the user. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a portable folding companion bed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable folding companion bed, including a modular bed, a rotating rod on one side of the modular bed, a combined bed on the surface of the rotating rod, a fixing component between the modular bed and the combined bed, the fixing component including a fixing groove and a fixing block, the fixing groove being opened on the side of the modular bed near the combined bed, the fixing block being fixedly connected to the side of the combined bed near the modular bed, a device groove being opened on the surface of the fixing block, a spring being fixedly connected inside the device groove, a limiting block cooperating with the fixing groove being fixedly connected to the end of the spring away from the device groove, and a pressing component being provided inside the fixing groove.
[0006] As a preferred technical solution of this utility model, the pressing component includes a first slide groove, which is opened on both sides of the inner cavity of the fixed groove. A first slider is slidably connected inside the first slide groove, and a pressing block that cooperates with the limiting block is fixedly connected between the two first sliders.
[0007] As a preferred technical solution of this utility model, a blocking component is provided on the outside of the rotating rod. The blocking component includes a second sliding groove and a blocking block. The second sliding groove is opened on both sides of the rotating rod, and a second slider is slidably connected inside the second sliding groove.
[0008] As a preferred technical solution of this utility model, a limiting sleeve is fixedly connected to the opposite side of each of the two second sliders. The end of the limiting sleeve away from the rotating rod is rotatably connected to a rotating sleeve that cooperates with the rotating rod. The rotating sleeve is externally threaded to the rotating rod. The blocking block is fixedly connected to one side of the splicing bed. A snap-fit block that cooperates with the blocking block is provided on the outside of the limiting sleeve.
[0009] As a preferred embodiment of this utility model, the bottom of each combination bed is provided with a pushing assembly, which includes a pushing rod and a fixing rod. The pushing rod is fixedly connected to one side of the combination bed, and the two fixing rods are fixedly connected to one side of the combination bed. The bottom of each fixing rod is fixedly connected with a pushing wheel.
[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are: This utility model achieves automatic and reliable locking in the folded state through the setting of the fixing component. When the splicing bed and the combination bed are fully folded and closed, the preload of the spring can automatically drive the limit block to pop out and insert into the fixing groove. Locking can be completed without manual operation, effectively preventing safety hazards and inconvenience caused by accidental unfolding during carrying or moving, and greatly improving the safety and portability of the product.
[0011] This invention achieves controllability and safety during the unfolding process through the setting of the blocking component. When the combined bed unfolds to a specific angle, the mechanical interference between the snap-fit block and the blocking block achieves temporary obstruction, effectively preventing it from falling due to gravity. Subsequently, the rotating sleeve drives the limiting sleeve to move axially, causing the second slider to disengage from the second slide groove, thereby accurately releasing the obstruction. This segmented unfolding mechanism fundamentally avoids the risk of the bed instantly unfolding and crashing to the ground, ensuring the safety of the user. Attached Figure Description

[0014] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0015] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a portable folding companion bed includes a modular bed 1. A rotating rod 11 is provided on one side of the modular bed 1, and a combined bed 12 is mounted on the surface of the rotating rod 11. A fixing assembly is provided between the modular bed 1 and the combined bed 12. The fixing assembly includes a fixing groove 20 and a fixing block 21. The fixing groove 20 is located on the side of the modular bed 1 near the combined bed 12. The fixing block 21 is fixedly connected to the side of the combined bed 12 near the modular bed 1. A device groove 22 is provided on the surface of the fixing block 21. The interior of the device groove 22... A spring 23 is fixedly connected. The end of the spring 23 away from the device groove 22 is fixedly connected to a limiting block 24 that cooperates with the fixed groove 20. A pressing component is provided inside the fixed groove 20. The pressing component includes a first slide groove 30. The first slide groove 30 is opened on both sides of the inner cavity of the fixed groove 20. A first slider 31 is slidably connected inside the first slide groove 30. A pressing block 32 that cooperates with the limiting block 24 is fixedly connected between the two first sliders. The combination bed 12 and the splicing bed 1 need to be used with corresponding support legs.
[0016] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the companion bed is in a fully folded state, the splicing bed 1 and the combination bed 12 are folded together by rotating the rod 11. At this time, the spring 23 in the fixing block 21 is in a naturally extended state, pushing the limiting block 24 outward to make it stably inserted into the fixing groove 20 on the splicing bed 1, realizing mechanical locking in the folded state and preventing accidental unfolding during transportation. When unfolding the companion bed, first press the pressing block 32 in the fixing groove 20 with your finger, so that it moves smoothly downward along the first sliding groove 30 through the first slider 31, and press down the limiting block 24 to compress the spring 23 and completely withdraw it from the fixing groove 20, thus releasing the folding lock.
[0017] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a blocking assembly is provided on the outside of the rotating rod 11. The blocking assembly includes a second slide groove 40 and a blocking block 41. The second slide groove 40 is opened on both sides of the rotating rod 11. A second slider 42 is slidably connected inside the second slide groove 40. A limit sleeve 43 is fixedly connected to the opposite side of the two second sliders 42. A rotating sleeve 44 that cooperates with the rotating rod 11 is rotatably connected to the end of the limit sleeve 43 away from the rotating rod 11. The rotating sleeve 44 is threadedly connected to the outside of the rotating rod 11. The blocking block 41 is fixedly connected to one side of the splicing bed 1. A snap-fit block 45 that cooperates with the blocking block 41 is provided on the outside of the limit sleeve 43. A pushing assembly is provided at the bottom of the combination bed 12.
[0018] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, lift the combined bed 12 upwards, allowing it to rotate and unfold around the rotating rod 11. When it unfolds to approximately a 45-degree angle, the blocking assembly begins to function. At this point, the user needs to manually rotate the rotating sleeve 44. Since the rotating sleeve 44 is threadedly connected to the rotating rod 11, the rotation will drive the rotating sleeve 44, along with the limiting sleeve 43, to move axially along the rotating rod 11. Guided by the second slider 42 and the second slide groove 40, the limiting sleeve 43 smoothly advances forward until the locking block 45 on it mechanically interferes with the blocking block 41 fixed on the combined bed 1, thereby preventing the combination. As the bed 12 continues to unfold rapidly downwards due to gravity, it acts as a safety barrier. When it is necessary to fully unfold the bed, the rotating sleeve 44 is rotated in the opposite direction. The rotation of the rotating sleeve 44 is converted into the axial movement of the limiting sleeve 43 through its threaded engagement with the rotating rod 11. This movement eventually causes the second slider 42 to disengage from the second slide groove 40. Once disengaged, the limiting sleeve 43 and its locking block 45 are decoupled from the entire rotating system, thereby completely separating from the blocking block 41 and removing the obstruction. At this point, the combined bed 12 can be smoothly unfolded to a horizontal use state.
[0019] refer to Figure 1 and Figure 2 As shown, the pushing assembly includes a pushing rod 50 and two fixed rods 51. The pushing rod 50 is fixedly connected to one side of the combination bed 12, and the two fixed rods 51 are fixedly connected to one side of the combination bed 12. A pushing wheel 52 is fixedly connected to the bottom of the fixed rod 51.
[0020] refer to Figure 1 and Figure 2 As shown, by holding the push rod 50, the entire folding bed can be easily moved to the storage position using the rolling action of the bottom push wheel 52 and the support structure of the fixed rod 51.
[0021] Working principle: Before use: Refer to Figure 1 and Figure 2 As shown, when the companion bed is in a fully folded state, the splicing bed 1 and the combination bed 12 are folded together by rotating the rod 11. At this time, the spring 23 in the fixing block 21 is in a naturally extended state, pushing the limiting block 24 outward to make it stably inserted into the fixing groove 20 on the splicing bed 1, realizing mechanical locking in the folded state and preventing accidental unfolding during transportation. At the same time, through the cooperation of the second slider 42 and the second sliding groove 40 on the rotating rod 11, the limiting sleeve 43 is assembled on the rotating rod 11, and the rotating sleeve 44 is rotated to make it in a non-interference position.
[0022] When using: Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when unfolding the companion bed, first press the pressing block 32 in the fixing groove 20 with your finger, so that it moves smoothly downward along the first slide groove 30 via the first slider 31. Press down the limiting block 24 to compress the spring 23 and completely disengage it from the fixing groove 20, releasing the folding lock. Then lift the combination bed 12 upward, so that it rotates and unfolds around the rotating rod 11. When it unfolds to about 45 degrees, the blocking component begins to function. At this time, the user needs to manually rotate the rotating sleeve 44. Since the rotating sleeve 44 is threadedly connected to the rotating rod 11, the rotation will drive the rotating sleeve 44 and the limiting sleeve 43 to move together along the axial direction of the rotating rod 11. The limiting sleeve 43 is guided by the second slider 42 and the second slide groove 40, smoothly... The mechanism moves forward until the locking block 45 on it mechanically interferes with the blocking block 41 fixed on the bed 1, thereby preventing the bed 12 from continuing to unfold rapidly downwards due to gravity, thus providing a safety barrier. When the bed needs to be fully unfolded, the rotating sleeve 44 is rotated in the opposite direction. The rotation of the rotating sleeve 44 is converted into the axial movement of the limiting sleeve 43 through its threaded engagement with the rotating rod 11. This movement eventually causes the second slider 42 to disengage from the second slide groove 40. Once disengaged, the limiting sleeve 43 and its locking block 45 are decoupled from the entire rotating system, thus completely separating from the blocking block 41 and removing the obstruction. At this point, the bed 12 can continue to unfold smoothly to a horizontal use state.
[0023] After use: Reference Figure 1 and Figure 2 As shown, when folding and storing, first lift the combination bed 12 upwards. When it is lifted to about a 45-degree angle, rotate the rotating sleeve 44 to put the blocking component in the blocking position to prevent accidents. Then continue folding. When the splicing bed 1 and the combination bed 12 are completely closed, the spring 23 in the device slot 22 pushes the limit block 24 to automatically pop out and lock into the fixing slot 20. A click sound indicates that the locking is complete. Finally, hold the push rod 50 and use the rolling action of the bottom push wheel 52 and the support structure of the fixing rod 51 to easily push the entire folding bed to the storage position.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
