Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a quick-connect guardrail mechanism and an operating table transfer cart. Background Technology

[0002] Hospital beds are generally equipped with guardrails, primarily to prevent patients from falling, assist in patient movement, and restrain patient behavior. Different guardrails may need to be replaced depending on the patient to ensure they truly serve their safety purpose. Guardrails also need cleaning when not in use, and guardrails used for a long time may show wear or damage. Traditional hospital bed guardrails mainly rely on bolt fixing or pin structures for connection. While this ensures stability, it is cumbersome in actual use, requiring tools for installation or disassembly, and is time-consuming, especially inefficient when adjusting patient position urgently. Bolts may loosen during use, requiring frequent inspection and maintenance. Dirt can easily accumulate in the bolt gaps, increasing the difficulty of cleaning and disinfection. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the existing technology and propose a quick-connect mechanism for guardrails, which can facilitate the disassembly and replacement of guardrails.

[0006] The guardrail ear is provided with a shaft insertion hole and a through hole, and the central axes of the shaft insertion hole and the through hole are cross-shaped.

[0007] The wrench holder is provided with a insert shaft, a telescopic post, a telescopic post hole, a wrench groove, and a wrench; the insert shaft is connected to the insert shaft hole; a telescopic post is provided in the telescopic post hole, and a spring is provided between the telescopic post and the bottom of the telescopic post hole; a wrench groove is opened in the middle of the telescopic post hole on the wrench holder, and a wrench is fixedly connected to the telescopic post; the wrench extends out of the wrench groove and can slide along the wrench groove to drive the telescopic post to insert into the through hole or retract from the through hole.

[0008] Preferably, the wrench groove is L-shaped, and an inwardly recessed locking groove is provided at the end of the wrench groove.

[0009] Preferably, the mounting surface of the insert hole and the mounting surface of the through hole intersect perpendicularly.

[0010] Preferably, the guardrail ear is provided with a guardrail ear mounting hole, which is used to fix the guardrail ear to the operating table transfer cart; the wrench seat is provided with a wrench seat mounting hole, which is used to fix the wrench seat to the guardrail mounting frame.

[0011] This utility model also provides an operating table transfer cart, wherein the operating table transfer cart is connected to the guardrail mounting frame by several quick-connect guardrail mechanisms.

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1-2 As shown, a quick-connect mechanism for guardrails includes a guardrail lug 1 and a wrench base 6.

[0027] The guardrail ear 1 is provided with a shaft insertion hole 3 and a through hole 2, and the central axes of the shaft insertion hole 3 and the through hole 2 are cross-shaped.

[0028] The wrench holder 6 is provided with a shaft 9, a telescopic post 8, a telescopic post hole, a wrench groove, and a wrench 7; the shaft 9 is connected to the shaft hole 3; the telescopic post 8 is provided in the telescopic post hole, and a spring 10 is provided between the telescopic post 8 and the bottom of the telescopic post hole; a wrench groove is opened in the middle of the telescopic post hole on the wrench holder 6, and the wrench 7 is fixedly connected to the telescopic post 8. The wrench 7 extends out of the wrench groove and can slide along the wrench groove to drive the telescopic post 8 to be inserted into the through hole 2 or retracted from the through hole 2.

[0029] The wrench groove is L-shaped, and an inwardly recessed latch is provided at the end of the wrench groove. This latch can lock the wrench 7 when the wrench is located at the end of the wrench groove, preventing the wrench 7 from sliding automatically.

[0030] The mounting surface of the insert hole 3 and the mounting surface of the through hole 2 intersect perpendicularly.

[0031] like Figure 2 As shown, the wrench 7 is connected to the telescopic column 8, and a spring 10 is provided between the telescopic column 8 and the wrench seat 6. The bottom of the wrench seat 6 is connected to the insert shaft 9.

[0032] The guardrail ear 1 is provided with a guardrail ear mounting hole 4, which is used to fix the guardrail ear 1 to the operating table transfer cart (the connection can be made by fixing screws); the wrench seat 6 is provided with a wrench seat mounting hole, which is used to fix the wrench seat 6 to the guardrail mounting frame 5.

[0033] The guardrail ears 1 or wrench seats 6 of this utility model can be a pair of mirror images of each other or the same structure. When the structures are arranged symmetrically, a pair of guardrail ears 1 are respectively set on both sides of the transfer vehicle, or a pair of wrench seats 6 are respectively set on the left and right sides of the guardrail mounting frame 5.

[0034] Example 2

[0036] The operating table described above uses several quick-connect guardrail mechanisms to connect the transfer cart and the guardrail mounting frame 5.

[0037] The top frame 14 of the operating table transfer cart has two rows of guardrail ears 1 facing each other, and there are two guardrail ears 1 in each row; there are two guardrail mounting frames 5, and wrench seats 6 are connected to both sides of each guardrail mounting frame 5. The guardrail ears 1 and wrench seats 6 are connected one-to-one, and guardrails 11 are connected to the guardrail mounting frame 5.

[0038] Installation and use of this utility model: Align the wrench seat 6 with the guardrail ear 1, turn the wrench 7 into the groove on the side, compress the spring 10 to retract the telescopic column 8 into the wrench seat 6, insert the two insert shafts 9 on the left and right sides of the guardrail mounting bracket 5 into the insert shaft holes 3 of the guardrail ear 1, turn the wrench 7, and the spring force of the spring 10 will push the telescopic column 8 into the through hole 2 of the guardrail ear 1, thus completing the guardrail installation; when the guardrail 11 needs to be replaced, the wrench 7 can be turned to remove the guardrail mounting bracket 5 as a whole, which is convenient for disassembly and assembly and quick for replacement.

[0039] Alternatively, the fixing screws between the guardrail mounting bracket 5 and the guardrail 11 can be removed to detach the guardrail 11 from the guardrail mounting bracket 5.

[0040] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.
