Description

Technical Field

[0001] The utility model relates to a connecting rod type guardrail structure used for a rehabilitation bed, belonging to the technical field of medical equipment. Background Art

[0002] Rehabilitation beds are essential medical devices for rehabilitation treatment. They are used for patient diagnosis, rest, injections, and postoperative rehabilitation. In order to adapt to the needs of patients and prevent them from rolling off the bed to improve their safety, guardrails are often required. Although the existing guardrail structure can realize the storage function, most of them are one-piece structures that are shipped together with the rehabilitation bed. The entire guardrail cannot be flexibly disassembled. When medical institutions need to install guardrails in batches, they also need to purchase new rehabilitation beds, which are expensive, and the old beds can only be transported in batches for recycling and idle treatment, wasting basic costs.

[0003] Therefore, it is urgent to propose a novel link type guardrail structure to solve the above technical problems. Utility Model Content

[0023] Specific implementation method 1: Combination Figure 1-Figure 7 The present embodiment is described. The linkage guardrail structure of the present embodiment comprises a quick-install mounting seat 1, a guardrail bottom beam 2, a guardrail top beam 3, a middle connecting rod 4, a positioning connecting rod 5, an L-shaped fixing seat 6, a limiting seat 7, a limiting slider 8, a clamping column 9 and a limiting spring 10. The guardrail bottom beam 2 is mounted on both sides of the rehabilitation bed 0 through the quick-install mounting seat 1. The two ends of the middle connecting rod 4 are respectively hinged to the guardrail bottom beam 2 and the guardrail top beam 3 through hinge seats. One end of the positioning connecting rod 5 is hinged to the guardrail bottom beam 2, and the other end is hinged to the limiting seat 7 through the L-shaped fixing seat 6. The limiting seat 7 is fixedly mounted on the guardrail top beam 3. The limiting slider 8 is slidably mounted in the limiting seat 7. The limiting spring 10 is mounted on the top of the limiting slider 8. The clamping column 9 is mounted on the bottom of the limiting spring 10. When in use, the bottom of the clamping column 9 passes through the limiting seat 7 and is placed in the limiting hole 61 on the L-shaped fixing seat 6.

[0024] The quick-release mounting seat 1 includes a fixing plate 11, a support plate 12, a quick-release support 13, a quick-release support shaft 14, a sliding column 15, a baffle 16, a tightening spring 17 and a pull rod 18. A waist-shaped hole 111 is processed on the fixing plate 11. The fixing plate 11 is fixedly connected to both sides of the rehabilitation bed 0 by bolts installed in the waist-shaped hole 111. At least two support plates 12 are installed at the bottom of the front side of the fixing plate 11. A quick-release support is installed on the front side of the fixing plate 11 above the support plate 12. 13. A quick-release support shaft 14 is horizontally installed on the bottom beam 2 of the guardrail, and the quick-release support shaft 14 is inserted in the quick-release support 13. A sliding column 15 is vertically slidably installed on the support plate 12. The bottom of the sliding column 15 is fixedly connected to the pull rod 18, and a baffle 16 is installed in the middle of the sliding column 15. A tightening spring 17 is sleeved on the outer side of the sliding column 15 between the baffle 16 and the support plate 12. The top of the sliding column 15 passes through the quick-release support 13 and the quick-release support shaft 14 in turn, and establishes a sliding connection with them.

[0025] During installation, as shown in the figure, the fixing plate 11 is fixedly installed on one side of the rehabilitation bed 0 by bolts or welding. When installing the guardrail, it is only necessary to manually pull the pull rod 18, as shown in the figure, to move the sliding column 15 downward, compress the tightening spring 17, and then insert the guardrail bottom beam 2 with the quick-release support shaft 14 into the quick-release support 13, loosen the pull rod 18, and reset the tightening spring 17. After the sliding column 15 passes through the quick-release support 13, it is inserted into the quick-release support shaft 14 to achieve quick installation and fixation;

[0026] When disassembling, just manually pull the pull rod 18, as shown in the figure, to move the sliding column 15 downward, compress the tension spring 17, and then pull the guardrail bottom beam 2 with the quick-release support shaft 14 out of the quick-release support 13, loosen the pull rod 18, and reset the sliding column 15 and the tension spring 17 to achieve quick disassembly;

[0027] In the usage state, as shown in the figure, hold the guardrail top beam 3 with one hand, press the limit slider 8, so that the limit slider 8 compresses the limit spring 10, and the clamping column 9 is retracted. At the same time, lift the guardrail top beam 3, and the middle connecting rod 4 and the positioning connecting rod 5 swing accordingly until the clamping column 9 is aligned with the limit hole 61 on the L-shaped fixing seat 6. Release your hand, release the limit slider 8, and the limit spring 10 is reset, so that the clamping column 9 pops out and is clamped into the limit hole 61, thereby realizing the limit fixation of the middle connecting rod 4, and the deployment and fixation of the entire link type guardrail structure is completed.

[0028] In the storage state, as shown in the figure, hold the guardrail top beam 3 with one hand, press the limit slider 8, so that the limit slider 8 compresses the limit spring 10, and the clamping column 9 is retracted. At the same time, the guardrail top beam 3 is pressed down, and the middle connecting rod 4 and the positioning connecting rod 5 swing accordingly, until the clamping column 9 is disengaged from the limit hole 61 on the L-shaped fixing seat 6, and the guardrail bottom beam 2 and the guardrail top beam 3 are stored as close as possible in space. Release your hand, release the limit slider 8, and the limit spring 10 is reset to make the clamping column 9 pop out, thereby completing the storage of the entire connecting rod guardrail structure.
