Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to an emergency bed with a small table. Background Technology
[0002] In emergency medical scenarios, emergency beds must simultaneously meet three core requirements: efficient space utilization, optimized operational efficiency, and equipment stability. Current traditional emergency bed table designs present significant contradictions: fixed structures occupy space around the bed, hindering equipment movement or patient transfer; simple folding tables, while foldable, pose a risk of collision due to protruding edges; existing height adjustment and fixing mechanisms rely on complex mechanical structures such as multi-level buckles and bolts, requiring two-handed operation and being time-consuming, making it difficult to meet the rapid response needs of emergency scenarios; furthermore, the singular functional zoning, such as a single flat table, leads to the mixing of medicines, instruments, and beverages, posing a risk of slippage or contamination, and lacks expandability.
[0003] In the prior art, the rigid structure of the fixed tabletop occupies the operating space around the bed, hindering the rapid movement of emergency equipment such as transport ventilators and defibrillators, and is prone to collision with medical carts / walls during patient transport; simple folding tabletops tend to retain protruding edges after folding, posing a high risk of collision with transport stretchers / mobile CT equipment in emergency passages, and the folding hinges are prone to breakage after frequent opening and closing, and the height of the fixed tabletop cannot be adjusted, making it difficult to adapt to the height of different patients and resulting in poor practicality. Therefore, this utility model discloses an emergency bed with a small tabletop to solve the problems of space occupation, collision safety hazards, and lack of height adjustment in traditional emergency bed tabletop designs. Utility Model Content

[0007] Preferably, the adjustment component includes multiple sets of mounting grooves, each set of mounting grooves is installed at the four corners of the lower end face of the table, and a rotating rod is installed on the inner wall of both ends of each set of table. A threaded rod is installed on the rotating rod, and an internally threaded tube is threaded onto the other end of the threaded rod. A sliding block is rotatably installed on the other end of the internally threaded tube. A sliding groove is provided on the bed frame corresponding to the position of the sliding block, and a second mounting groove is provided on one side of the sliding block. A limiting cylinder is slidably installed in the second mounting groove. One end of the limiting cylinder protrudes from the side wall of the sliding block, and the protruding end of the limiting cylinder is circular. A limiting ring is fixedly installed on the arc wall of the limiting cylinder located in the second mounting groove. A second spring is sleeved on the limiting cylinder, and a set of elastic limiting buckles is installed on the lower end face of the table corresponding to the position of the internally threaded tube.
[0008] Preferably, each set of threaded rods has a circular hole with the same diameter as the rotating rod at the position corresponding to the rotating rod, and the threaded rod fits into the internal threaded tube, the internal threaded tube fits into the elastic limiting buckle, and the sidewall of the sliding groove has a uniform array of circular grooves that fit into the limiting cylinder, and the sliding block has a cylindrical groove with the same diameter as the internal threaded tube at the position corresponding to the internal threaded tube, and the internal threaded tube and the sliding block are engaged and rotated together.
[0009] Preferably, the diameter of the second spring is the same as the maximum diameter of the limiting ring, and one end of the second spring is installed on the side wall of the limiting ring, while the other end of the second spring is installed on the inner wall of the second mounting groove.
[0010] Preferably, the fixing component includes a first mounting groove, which is formed on the lower side wall of the storage box. An L-shaped locking block is installed in the first mounting groove. The short side of the L-shaped locking block protrudes from the inner wall of the storage box, and the end of the short side of the storage groove is beveled. A sliding guide rod is installed at the bottom of the long outer wall of the L-shaped locking block. The other end of the sliding guide rod is fixedly installed on the side wall of the first mounting groove, and a first spring is sleeved on the sliding guide rod.

[0012] The beneficial effects of this utility model are:
[0013] This solution utilizes a retractable tabletop design, combining a storage box with securing components to alleviate the space encroachment of traditional fixed tabletops around the emergency bed. The tabletop, once stowed, is embedded in the bottom of the bed frame, ensuring unobstructed and rapid movement of emergency equipment such as ventilators and defibrillators, while also preventing collisions with medical carts, walls, or mobile CT scanners during patient transport. Compared to the protruding edges of simple folding tabletops, this solution employs a dual securing mechanism of L-shaped locking blocks and electromagnets, ensuring no exposed parts when the tabletop is fully retracted.
[0014] This solution achieves table height adjustment through the coordinated action of a threaded rod-internal threaded tube transmission mechanism and a sliding block limiting system. Medical personnel only need to achieve precise height positioning by engaging the threaded rod with the internal threaded tube. The automatic engagement of the sliding block's side-wall limiting cylinder with the sliding groove ensures the equipment's stability meets the needs of emergency scenarios.
[0015] The tabletop surface features a combination of storage slots, cup holders, and anti-slip textures to physically separate medicines, instruments, and beverages. The depth of the storage slots prevents tipping. Inside the storage box, a combination of a copper enameled wire coil electromagnet and a neodymium iron boron permanent magnet on the tabletop automatically secures the tabletop in its stored state. When the controller energizes the copper enameled wire coil electromagnet, it generates a magnetic force, increasing the bonding strength between the tabletop and the storage box and preventing loosening due to vibrations during transportation.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0026] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0027] This utility model provides, for example Figures 1 to 6The emergency bed with a small table shown includes: a bed frame 1, with a set of support frames 2 installed at both ends of the bottom of the bed frame 1, and guardrails 3 installed on both sides of the upper end of the bed frame 1. Multiple sets of bed boards 4 are evenly arranged on the upper surface of the bed frame 1. A table 6 is installed directly above the bed frame 1. A lifting strap 25 is installed in the middle of the lower surface of the table 6. One end of the upper surface of the table 6 is provided with anti-slip texture 9. The other end of the upper surface of the table 6 is provided with a storage slot 7. A cup slot 8 is provided on one side of the storage slot 7. An adjustment component is provided below the table 6 to adjust the height of the table 6. A storage box 5 is installed on the lower surface of the bed frame 1. The storage box 5 is provided with a fixing component to fix the table 6. This solution alleviates the problem of traditional fixed table 6 occupying the space around the emergency bed by designing a retractable table 6, combined with the functions of the storage box 5 and the fixing component. After being folded up, the tabletop 6 is embedded in the bottom of the bed frame 1, ensuring unobstructed and rapid movement of emergency equipment such as ventilators and defibrillators, while avoiding the risk of collisions with medical carts, walls, or mobile CT equipment during patient transport. Compared to the protruding edge hazards of simple folding tabletops 6, this solution uses a dual fixing mechanism of L-shaped locking block 17 and electromagnet to ensure that there are no exposed parts when the tabletop 6 is fully folded up. This solution achieves height adjustment of the tabletop 6 through the coordinated action of the threaded rod 10-internal threaded tube 11 transmission mechanism and the sliding block 14 limiting system. Medical staff only need to use the threaded engagement of the threaded rod 10 and the internal threaded tube 11 to achieve precise height positioning. With the automatic engagement of the limiting cylinder 21 on the side wall of the sliding block 14 and the circular groove of the sliding groove 24, the stability of the tabletop 6 is ensured, thus ensuring the stability of the equipment meets the needs of emergency scenarios. The surface of the tabletop 6 uses a combination design of storage slots 7, cup slots 8, and anti-slip textures 9 to achieve physical isolation of medicines, instruments, and beverages. The depth of the storage slot 7 prevents tipping; the combination of the copper enameled wire coil winding electromagnet 15 inside the storage box 5 and the neodymium iron boron permanent magnet of the tabletop 6 automatically fixes the tabletop 6 in its stored state. When the controller energizes the copper enameled wire coil winding electromagnet 15, the energized electromagnet 15 generates a magnetic attraction force, which increases the bonding strength between the tabletop 6 and the storage box 5, preventing loosening caused by transportation vibrations.
[0028] Furthermore, in this example, such as Figure 2 and Figure 6As shown, the adjustment assembly includes multiple sets of mounting grooves 13. Each set of mounting grooves 13 is installed at the four corners of the lower end face of the table 6. A rotating rod is installed on the inner wall of both ends of each set of table 6. A threaded rod 10 is installed on the rotating rod. An internally threaded tube 11 is threaded onto the other end of the threaded rod 10. A sliding block 14 is rotatably installed on the other end of the internally threaded tube 11. A sliding groove 24 is provided on the bed frame 1 at the position corresponding to the sliding block 14. A second mounting groove 20 is provided on one side of the sliding block 14. A limiting cylinder 21 is slidably installed in the second mounting groove 20. One end of the limiting cylinder 21 protrudes from the side wall of the sliding block 14, and the protruding end of the limiting cylinder 21 is circular. A limiting ring 22 is fixedly installed on the arc wall of the limiting cylinder 21 in the second mounting groove 20. A second spring 23 is sleeved on the limiting cylinder 21. A set of elastic springs is installed on the lower end face of the table 6 at the position corresponding to the internally threaded tube 11. The limiting buckle 12 has a circular hole with the same diameter as the rotating rod at the position of each threaded rod 10. The threaded rod 10 fits into the internal threaded tube 11, and the internal threaded tube 11 fits into the elastic limiting buckle 12. The side wall of the sliding groove 24 has a uniform array of circular grooves that fit into the limiting cylinder 21. The sliding block 14 has a cylindrical groove with the same diameter as the internal threaded tube 11 at the position of the internal threaded tube 11. The internal threaded tube 11 and the sliding block 14 are installed in a locking and rotating manner. The diameter of the second spring 23 is the same as the maximum diameter of the limiting ring 22. One end of the second spring 23 is installed on the side wall of the limiting ring 22, and the other end of the second spring 23 is installed on the inner wall of the second mounting groove 20. When the height of the table 6 needs to be adjusted, the threaded rod 10 is rotated. At this time, the table 6 moves the threaded rod 10 upward synchronously through the four corner mounting grooves 13. When the tabletop 6 is lifted to the target height, and the distance of the tabletop 6 needs to be adjusted, the tabletop 6 is pushed. At this time, the limiting ring 22 on the limiting cylinder 21 inside the sliding block 14 will squeeze the second spring 23. When the limiting cylinder 21 retracts and separates from the circular groove on the side wall of the sliding groove 24, the sliding block 14 can move back and forth. When it reaches the predetermined position, the potential energy stored in the second spring 23 will push the limiting ring 22, and the limiting ring 22 will drive the limiting cylinder 21 to re-enter the new circular groove, completing the positioning.
[0029] Furthermore, in this example, such as Figure 3 , Figure 4 and Figure 5As shown, the fixing assembly includes a first mounting groove 16, which is formed on the lower side wall of the storage box 5. An L-shaped locking block 17 is installed in the first mounting groove 16. The short side of the L-shaped locking block 17 protrudes from the inner wall of the storage box 5, and the short side of the storage slot 7 is beveled. A sliding guide rod 18 is installed at the bottom of the long side outer wall of the L-shaped locking block 17. The other end of the sliding guide rod 18 is fixedly installed on the side wall of the first mounting groove 16, and a first spring 19 is sleeved on the sliding guide rod 18. A positioning groove is formed on the side wall of the storage box 5 corresponding to the position of the L-shaped locking block 17. A copper enameled wire coil winding electromagnet 15 is installed in the middle of the bottom wall of the storage box 5. A controller is installed on the outer wall of the storage box 5, and a neodymium iron boron permanent magnet is installed on the table 6 at the position corresponding to the copper enameled wire coil winding electromagnet 15. One end of the first spring 19 is installed on the side wall of the first mounting groove 16, and the other end of the first spring 19 is installed on the long side wall of the L-shaped locking block 17. The L-shaped locking block 17 has a circular hole with the same diameter as the sliding guide rod 18 at the position corresponding to the sliding guide rod 18. The sliding guide rod 18 is slidably inserted into the circular hole. When the table 6 is pressed down into the storage box 5, the edge of the table 6 first contacts the short side of the inclined surface of the L-shaped locking block 17, pushing the L-shaped locking block 17 to retract along the sliding guide rod 18 and compress the first spring 19. After the table 6 is fully inserted into the storage box 5, the L-shaped locking block 17 is reset under the action of the rebound force of the first spring 19, and its short side is locked into the positioning groove on the edge of the table 6, forming the first mechanical lock. Simultaneously, after the controller detects the arrival signal of the tabletop 6, it energizes the copper enameled wire coil winding electromagnet 15. The electromagnet generates a magnetic force that attracts the neodymium iron boron permanent magnet on the lower end of the tabletop 6, forming a second electromagnetic lock. The superposition of magnetic force and mechanical engagement significantly increases the bonding strength between the tabletop 6 and the storage box 5, resisting impacts during transportation. Furthermore, if the tabletop 6 experiences slight displacement due to vibration, the change in the magnetic gap between the electromagnet and the permanent magnet will cause a nonlinear enhancement of the magnetic force, automatically compensating for the displacement and achieving dynamic stability. When the tabletop 6 needs to be removed, the medical staff presses the release button on the controller, de-energizing the electromagnet and eliminating the magnetic force. When manually lifting the tabletop 6, pressure is applied by flicking the inclined surface of the L-shaped locking block 17 with a finger, compressing the first spring 19 and causing the L-shaped locking block 17 to retract, releasing the mechanical engagement. If the electromagnet loses power due to a malfunction, it can be forcibly unlocked by connecting an external backup power supply or by manually pressing the end of the L-shaped locking block 17. The guiding design of the sliding guide rod 18 ensures that the L-shaped locking block 17 moves only in the horizontal direction, avoiding jamming.
