Description

Technical Field

[0001] This utility model relates to the field of examination bed technology, and in particular to an examination bed with an automatic changeable liner. Background Technology

[0002] During medical examinations, disposable sheets are typically laid on the examination bed to ensure hygiene and safety. Traditional examination beds use a structure with unwinding and rewinding rollers at both ends, achieving automatic sheet replacement through unidirectional transmission. While this structure enables automatic sheet replacement, it has significant drawbacks in practical use. First, when the unwinding roller rotates to release the sheet, the sheet exerts a continuous pulling force on it. This force can easily cause the connection between the unwinding roller and the bed frame to loosen or even completely detach, affecting normal equipment operation and potentially creating safety hazards. Second, when changing the sheet roll, operators must disassemble multiple connecting parts to remove the unwinding or rewinding roller from the bed frame. This cumbersome disassembly and assembly process significantly reduces the work efficiency of medical staff, especially in examination scenarios requiring frequent sheet changes. Furthermore, the current technology lacks an effective anti-detachment mechanism to ensure the stable positioning of the rotating roller in the longitudinal direction, further exacerbating safety hazards during equipment use.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] Reference Figures 1 to 4 This utility model provides an inspection bed with an automatically changeable sheet, including a bed body 100 connected to a liftable bed frame 200. The bed frame 200 can adjust the vertical position of the bed body 100. Rotating rollers 400 are provided at both ends of the bed frame 200. A sheet 300 is laid on the bed body 100, with one end of the sheet 300 wound around one of the rotating rollers 400 and the other end wound around the other rotating roller 400. One of the two rotating rollers 400 is used to reel in unused sheets. 300, the other of the two rotating rollers 400 is used to rewind the used pad sheet 300; anti-detachment mechanism 500 includes a first limiting part disposed on the bed frame 200 and a second limiting part disposed on the rotating roller 400, the rotating roller 400 can drive the second limiting part to connect with the first limiting part; wherein, when the second limiting part is connected with the first limiting part, the rotating roller 400 can rotate relative to the second limiting part, and the second limiting part and the first limiting part can prevent the rotating roller 400 from being displaced in the longitudinal direction.

[0038] Understandably, after the patient completes the examination, the lifting mechanism 210 drives the bed 100 to descend to its lowest position, at which point the rotating roller 400 initiates its winding action. Unused sheets 300 are unrolled from one rotating roller 400, while the used portion is wound up by another rotating roller 400. During this process, the first and second limiting parts of the anti-detachment mechanism 500 remain engaged, completely restricting the longitudinal displacement of the rotating roller 400 and preventing it from detaching from the bed frame 200 due to the tension of the sheets 300. When it is necessary to replace the sheet roll, the operator pushes the rotating roller 400 to disengage the second limiting part from the first limiting part, allowing the rotating roller 400 to be removed from the bed frame 200. After replacing with a new roll, the rotating roller 400 is reinstalled on the bed frame 200. This effectively prevents axial displacement of the rotating roller 400 due to the tension of the sheets 300 during unwinding and winding, avoiding potential safety hazards during equipment operation.

[0039] According to some embodiments of this application, the bed frame 200 is provided with a columnar limiting member 510, which is a first limiting part. One end of the rotating roller 400 is provided with a slot 531, which is a second limiting part. The limiting member 510 can engage with the slot 531. Specifically, as shown in the figure, the rotating roller 400 includes a roller body and a mounting assembly. The mounting assembly includes a connecting shaft 520 and a first mounting plate 530. The connecting shaft 520 is detachably connected to the bed frame 200. The first mounting plate is connected to one end of the connecting shaft 520, and the other end of the connecting shaft 520 is connected to the roller body. The slot 531 is provided on the first mounting plate 530.

[0040] As can be understood, as shown in the figure, when the rotating roller 400 is installed with the bed frame 200 and the pad 300 is replaced, the pad 300 pulls the rotating roller 400 to rotate. At this time, the rotating roller 400 can drive the first mounting plate 530 to rotate at the same time, so that the slot 531 and the limiting member 510 are engaged. After the slot 531 engages with the limiting member 510, the first mounting plate 530 is fixed and constrained by the slot 531 and the limiting member 510. The first mounting plate 530 cannot continue to rotate with the rotating roller 400. The rotating roller 400 continues to rotate under the continuous pulling force of the pad 300, causing the rotating roller 400 and the first mounting plate 530 to rotate relative to each other. The first mounting plate 530 also maintains a tendency to rotate in the same direction as the rotating roller 400, so that the slot 531 and the limiting member 510 maintain a stable engagement. Under the cooperation of the slot 531 and the limiting member 510, the rotating roller 400 can remain stable in the longitudinal direction. The pulling force generated by the pad 300 on the rotating roller 400 cannot pull the rotating roller 400 away from the mounting position on the bed frame 200, avoiding the risk of equipment detachment due to pulling force, while ensuring the free rotation function of the rotating roller 400.

[0041] Specifically, the limiting component 510 is a screw.

[0042] According to some embodiments of this application, the bed frame 200 is provided with a second mounting plate 230, a limiting member 510 is connected to the second mounting plate 230, the second mounting plate 230 is provided with a mounting groove 240, and a connecting shaft 520 is connected to the mounting groove 240.

[0043] Understandably, when it is necessary to replace the 300 roll of padding sheet, the operator first disengages the limiting member 510 from the slot 531, and then lifts the rotating roller 400 to disengage the connecting shaft 520 from the mounting groove 240. Conversely, when the operator installs the rotating roller 400, the connecting shaft 520 is pushed into the predetermined position along the mounting groove 240. This achieves quick disassembly and reliable fixation of the rotating roller 400. The operator can quickly complete the roller replacement without special tools. Furthermore, the constraint relationship between the limiting member 510 and the slot 531 can also eliminate the risk of longitudinal displacement during the winding process of the 300 padding sheet.

[0044] Specifically, as shown in the figure, the mounting groove 240 includes a first groove 241 and a second groove 242 that are inclined. The first groove 241 and the second groove 242 are designed at an angle. The first groove 241 has an opening that faces upward. The connecting shaft 520 passes through the first groove 241 and connects to the second groove 242.

[0045] Understandably, during the installation of the rotating roller 400, the connecting shaft 520 slides into the first groove 241 from the opening along the inclined direction and naturally slides down to the end of the second groove 242 under gravity. Specifically, during installation, the connecting shaft 520 first slides along the inclined direction of the first groove 241. The inclined structure guides the connecting shaft 520 downward. When the connecting shaft 520 reaches the end of the first groove 241, it is constrained by the included angle design and turns into the second groove 242. At this time, the lateral extension direction of the second groove 242 restricts the longitudinal displacement of the connecting shaft 520. During disassembly, the connecting shaft 520 slides in the opposite direction along the second groove 242 to the junction of the first groove 241. Due to the bending obstruction formed by the included angle design, a specific angle of external force is required to detach it, thereby preventing accidental detachment. Compared with the traditional mounting groove 240, which adopts a straight structure in one direction, the connecting shaft 520 is fixed only by friction, making it prone to displacement under dynamic loads. This application achieves self-locking of the connecting shaft 520 during sliding by using both tilting guidance and bending limit, which can achieve stable fixation without additional fasteners and simplifies the disassembly and assembly steps.

[0046] According to some embodiments of this application, a lifting member 532 is provided on the first mounting plate 530, and one end of the lifting member 532 is hinged to the first mounting plate 530. It is understood that when it is necessary to disassemble the rotating roller 400, the operator can lift the rotating roller 400 using the lifting member 532, thereby disengaging the connecting shaft 520 from the mounting groove 240. After disassembly, the lifting member 532 can be folded back to its original position around the hinge axis, avoiding the occupation of additional space.

[0047] According to some embodiments of this application, the bed frame 200 includes a lifting mechanism 210 and a base frame 220. The lifting mechanism 210 is disposed on the base frame 220, and the bed body 100 is connected to the lifting mechanism 210. The lifting mechanism 210 may be a hydraulic cylinder or an electric push rod, etc.
