Description
Technical Field
[0001] This utility model relates to the field of hospital bed technology, specifically to a vertical X-frame sliding lifting device with a four-fold load-bearing capacity. Background Technology
[0002] In conventional hospital beds, adjusting the overall height of the bed and enabling patients to sit up or raise their legs are mostly achieved using a manual rotating wheel and worm gear structure. This operation is very cumbersome, costly, and impractical.
[0003] Utility model patent CN208541496U discloses a liftable hospital bed, including a bed frame, a first connecting member, a second connecting member, a base, a constraint rod, a first power device that can extend and retract, and a second power device that can extend and retract. One end of the first connecting member is hinged to the bed frame, and the other end is slidably engaged with the base. One end of the first power device is hinged to the bed frame, and the other end is hinged to the first connecting member. One end of the second connecting member is hinged to the bed frame, and the other end is slidably engaged with the base. One end of the second power device is hinged to the bed frame, and the other end is hinged to the second connecting member.
[0004] The existing lift-type hospital beds use dual-power devices to control the bed's ascent, descent, and overall tilting processes. The triangular support structure, combined with the sliding mechanism, ensures that the distance between the bed frame and the base remains constant during ascent and descent. The bed's transitions are smooth and fluid, and the sliding mechanism effectively reduces noise, thus ensuring the patient's rest.
[0005] However, existing lifting hospital beds use a dual-power unit in conjunction with a first connecting piece, a second connecting piece, and a constraint rod to achieve lifting and tilting. This design requires coordination of multiple transmission components, resulting in a complex overall structure. During frequent movement, the hinge points and sliding parts are prone to loosening due to wear, requiring regular maintenance and replacement of parts, which increases maintenance costs and workload. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a vertical X-frame sliding lifting device with a four-fold load-bearing capacity, thus solving the problems of existing technologies.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a vertical X-frame sliding lifting device with a four-fold load-bearing capacity, comprising a bed base frame, a vertical X-frame sliding lifting device, a bed frame, and a bed panel; the vertical X-frame sliding lifting device is disposed between the bed base frame and the bed frame, and is used to realize the lifting and tilting movements of the bed frame and the bed panel.
[0008] Preferably, the bed frame includes four frame steel pipes, a lifting pulley track, and four medical casters; the medical casters are short-axle silent casters installed at the bottom of the bed frame; the medical casters also include brake brackets and brake linkages for braking the casters; the lifting pulley track is located inside the frame steel pipes of the bed frame.
[0009] Preferably, the vertical X-frame sliding lifting device includes two base frame lifting square tubes, a base frame roller connecting shaft, a lifting and lowering linkage, and base frame pulleys; the base frame pulleys are installed at both ends of the base frame roller connecting shaft and are slidably disposed within the lifting pulley track; base frame pulley stops are provided at both ends of the lifting pulley track to limit the movement of the base frame pulleys.
[0010] Preferably, the base frame lifting square tube is fixedly connected to the base frame roller connecting shaft, and the base frame lifting square tube is connected to the bed frame through the bed frame lifting bracket; a lifting motor bracket is welded to the upper end of the base frame roller connecting shaft for mounting the drive motor, and the drive motor is used to control the movement of the vertical X-frame sliding lifting device.
[0011] Preferably, the vertical X-frame sliding lifting device connects two base frame lifting square tubes and the base frame roller connecting shaft through the lifting and lowering linkage to form an X-frame structure. The X-frame structure can evenly distribute the load to each support point, achieving a load-bearing capacity four times that of ordinary lifting devices.
[0012] Preferably, the bed frame is equipped with a headboard, a footboard, a small guardrail, a large guardrail, and anti-collision wheels; the bed panel is installed above the bed frame and is vertically raised and lowered by the vertical X-frame sliding lifting device, and will not shift during the raising and lowering process. Beneficial effects
[0013] This invention provides a vertical X-frame sliding lifting device with a load-bearing capacity of four times. Compared with the prior art, it has the following advantages: 1. This vertical X-frame sliding lifting device, with a load-bearing capacity four times greater, utilizes a vertical X-frame sliding lifting mechanism. It connects two base frame lifting square tubes and base frame roller connecting shafts via lifting and lowering linkages to form an X-frame structure. This structure can evenly distribute the load to each support point. Compared to traditional I-frame or dual-powered triangular structures, its load-bearing capacity is increased to four times that of a standard hospital bed. This not only ensures the safety of heavier patients but also meets the heavy-load requirements for placing medical equipment and rehabilitation training, thus broadening its application scenarios.
[0014] 2. This vertical X-frame sliding lifting device with a four-fold load-bearing capacity has geometric stability in its structure. Combined with the limiting design of the base frame pulleys and lifting pulley tracks, it ensures that the bed moves only in the vertical direction during lifting and lowering, without horizontal translation or swaying. Through the rigid X-frame and precise guiding device, the risk of bed tilting or vibration is effectively reduced, improving patient comfort and safety. It is especially suitable for medical scenarios with high requirements for lifting and lowering stability. Attached Figure Description

[0017] 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.
[0018] like Figure 1-4 As shown, this utility model provides two technical solutions: The first embodiment is a vertical X-frame sliding lifting device with a four-fold load-bearing capacity, including a bed base frame 4, a vertical X-frame sliding lifting device 3, a bed frame 2, and a bed panel 1; the vertical X-frame sliding lifting device 3 is disposed between the bed base frame 4 and the bed frame 2, and is used to realize the lifting and tilting movements of the bed frame 2 and the bed panel 1.
[0019] The bed frame 4 includes four frame steel pipes 5, lifting pulley rails 6, and four medical casters 7. The medical casters 7 are short-axle silent casters, installed at the bottom of the bed frame 4, which lowers the minimum height of the bed, expands the range of forward and backward tilt angles, and improves flexibility. The medical casters 7 also include brake brackets 15 and brake linkages 16. The brake brackets 15 are fixed to the caster brackets, and one end of the brake linkage 16 is hinged to the brake brackets 15, while the other end is controlled by a foot pedal mechanism. When the brake linkage 16 is pressed, the rotation of the caster can be locked to achieve the braking function. The lifting pulley rails 6 are located inside the frame steel pipes 5 of the bed frame 4.
[0020] The vertical X-frame sliding lifting device 3 includes two base frame lifting square tubes 8, a base frame roller connecting shaft 9, a lifting linkage 10, and base frame pulleys 11. The base frame pulleys 11 are installed at both ends of the base frame roller connecting shaft 9 and are slidably set in the lifting pulley track 6. Pulley stops 12 are provided at both ends of the lifting pulley track 6 to limit the base frame pulleys 11. The base frame lifting square tubes 8 are fixedly connected to the base frame roller connecting shaft 9. The base frame lifting square tubes 8 are connected to the bed frame 2 through the bed frame lifting bracket 13 to ensure reliable transmission of lifting power and realize the overall forward and backward tilt adjustment of the bed. The upper end of the base frame roller connecting shaft 9 is welded with a lifting motor bracket for mounting the drive motor. The drive motor controls the movement of the vertical X-frame sliding lifting device 3. The vertical X-frame sliding lifting device 3 connects two base frame lifting square tubes 8 and the base frame roller connecting shaft 9 through the lifting linkage 10 to form an X-frame structure. When the pulleys slide, geometric deformation occurs, converting horizontal sliding into vertical lifting motion. The rigid structure of the X-frame itself reduces swaying and offset during the lifting process. The X-frame structure can evenly distribute the load to each support point, achieving a load-bearing capacity four times that of ordinary lifting devices.
[0021] When the base frame pulley 11 slides outward along the track, the X-frame structure unfolds, pushing the bed frame lifting bracket 13 upward, causing the bed frame 2 and bed panel 1 to rise. When the pulley slides inward, the X-frame structure retracts, and the bed frame 2 and bed panel 1 descend.
[0022] The second implementation method differs from the first implementation method in that: the bed frame 2 is equipped with a headboard and footboard 14, a small guardrail 17, a large guardrail 18, and bed frame anti-collision wheels 19; the bed panel 1 is installed above the bed frame 2 and is vertically lifted and lowered by a vertical X-frame sliding lifting device 3, and will not shift during the lifting and lowering process.
[0023] When the device is in operation, the motor is started, and the motor drives the base frame roller connecting shaft 9 through the lifting motor bracket, which in turn drives the base frame pulley 11 to slide within the track. The X-frame structure evenly distributes the load, ensuring load-bearing capacity and stability. The track limit and guide device ensures precise lifting trajectory, and the bed panel 1 completes vertical lifting to meet the needs of patient position adjustment, medical equipment placement, etc. When it is necessary to fix the hospital bed, the foot brake linkage 16 is used to lock the casters using the brake bracket 15 to achieve bed positioning. When the brake is released, the caster movement function can be restored by operating the brake linkage 16 again.
