Description

Technical Field

[0001] The invention relates to the field of medical devices, and more particularly to a toggle-type limitless guardrail switch structure. Background Art

[0002] At present, medical beds are all equipped with guardrails, which are mainly composed of a guardrail frame 1 and a railing 4 arranged in the middle of the guardrail frame. In the commonly used installation method, multiple guardrails are required to be sequentially enclosed around the medical bed, which requires that the guardrails can be installed sequentially and continuously, and at the same time, two adjacent guardrails can be opened to form a switch door, that is, a certain guardrail can rotate around the installation rod 2. In this structure, a hollow installation rod 2 is generally fixed vertically on the side of the guardrail, and one side of the guardrail frame 1 is set to be disconnected, that is, the upper and lower ends of the guardrail frame 1 on this side can be rotated and installed to the upper and lower ends of the installation rod 2, thereby realizing that the entire guardrail frame can rotate around the installation rod 2.

[0003] However, with the improvement of high-end medical care standards and requirements, the current medical beds require that the guardrails can be locked as needed to ensure that they can be rotated only when needed and at a fixed angle as needed. Figure 1-3 The structure shown is that a mounting rod 2 is arranged between the upper and lower ends of the opening on one side of the guardrail frame, the upper connection portion of the guardrail frame 1 and the mounting rod 2 is formed by arranging at least one stopper tooth 5 with a protrusion along the diameter at the upper end of the opening of the guardrail frame, and the upper end of the mounting rod 2 is provided with corresponding at least two stopper grooves 6 along the diameter, the upper and lower connection portions of the guardrail frame 1 and the mounting rod 2 are positioned and connected through a fixed sleeve, and there is a certain distance between the lower connection mounting rod 2 and the lower end of the guardrail frame opening. In this way, the guardrail frame can be lifted up and down in the opening of the fixed sleeve, and the stopper tooth 5 is lifted from the stopper groove 6 during the lifting process, so that the guardrail frame can be rotated to a certain angle to the next stopper groove, thereby achieving the purpose of rotating the guardrail frame to a predetermined angle.

[0004] However, although the limit groove 6 and the limit tooth 5 are engaged with each other to prevent rotation, the guardrail frame can be rotated to a specified angle position only by slightly lifting the limit tooth beyond the limit groove. This can easily cause misoperation during use. Therefore, it is urgent to design a limit guardrail switch, which can lift the guardrail to rotate when needed, and keep the guardrail locked and unable to rotate when not needed. Summary of the invention

[0005] The present invention proposes a toggle-type unlimited-position guardrail switch structure, which can drive the card plate to move left and right when the paddle on the guardrail switch is toggled left and right, so that the card plate can be extended into or out of the space between the lower end of the guardrail frame opening and the lower end of the mounting rod, thereby blocking whether the guardrail frame can be lifted up for rotation, thereby solving the problems existing in the background technology.

[0026] like Figure 4 The structure of a toggle-type limitless guardrail switch is shown. The guardrail switch 3 includes a sealed hollow fixed shell composed of a guardrail switch front cover 32 and a guardrail switch rear cover 31 that are matched and snapped together. The hollow fixed shell is provided with a guardrail installation socket 33 that passes through the top and the bottom. The guardrail installation socket 33 is respectively composed of semicircular arcs on the corresponding sides of the guardrail switch front cover 32 and the guardrail switch rear cover 31; a fixing seat 34 is provided on the outer side of the hollow fixed shell, and a linear slide groove 35 extending to both ends is provided on the side surface of the fixing seat 34. The extension line of the linear slide groove 35 passes through the hollow fixed shell, and a slider 36 is matched in the linear slide groove 35. A card plate 37 is provided at one end of the slider 36 close to the hollow fixed shell; an opening 310 is provided on the side wall of the hollow fixed shell and corresponding to the card plate 37. The card plate 37 extends into or out of the hollow fixed shell through the opening 310 with the linear displacement of the slider 36.

[0027] In this embodiment, the guardrail switch back cover 31 includes a left guardrail switch back cover 311 and a right-left guardrail switch back cover 312, and the guardrail switch front cover 32 includes a left guardrail switch front cover 321 and a right guardrail switch front cover 322; the left guardrail switch back cover 311 and the left guardrail switch front cover 321 constitute a guardrail mounting shell, and the right-left guardrail switch back cover 312 and the right guardrail switch front cover 322 constitute a guardrail switch mounting shell; the guardrail mounting socket 33 is arranged on the guardrail mounting shell; the guardrail mounting shell and the guardrail switch mounting shell are hollow and internally connected, and the connecting portion forms an opening 310.

[0028] The slider 36 is fixed with a paddle block 38, and a paddle hole 323 is provided at a corresponding position on the guardrail switch mounting housing, and the end of the paddle block 38 passes through the paddle hole 323 from the inside to the outside of the guardrail switch mounting housing to realize linear displacement of the slider when the paddle block 38 is moved; the paddle block 38 includes a paddle 382 and a fixing plate 381, and the paddle 382 is provided on the top surface of the paddle fixing plate 381, and the bottom surface of the paddle fixing plate 382 is in contact with the side wall surface of the fixing seat 34 provided with a linear slide groove 35, and the bottom surface of the fixing plate 381 and the side wall surface of the fixing seat 34 provided with a linear slide groove 35 are both planar; the top end of the paddle 382 passes through the paddle hole 323 from the inside to the outside of the guardrail switch mounting housing. Preferably, the hollow fixing shell is also provided with a railing fixing hole 39 that passes through the top and bottom ends, and the fixing hole railing 39 is located on the guardrail switch mounting housing.

[0029] In the present invention, in order to realize that the guardrail frame can be rotated by lifting the guardrail frame, in actual operation, the guardrail switch is installed at the connection between the mounting rod 2 and the lower end of the guardrail frame opening. Figure 5-9 shown.

[0030] The lower end of the mounting rod 2 and the lower end of the guardrail frame are inserted into the upper and lower holes of the guardrail mounting socket 33 on the guardrail mounting housing, respectively. The lower end of the mounting rod 2 and the lower end of the guardrail frame are designed to maintain a certain distance, and when the paddle 382 is moved to the leftmost side, the card plate 37 is between the mounting rod 2 and the guardrail frame 1. The railing fixing hole 39 on the guardrail switch mounting housing on the other side is inserted into the railing 4 in the guardrail frame to play a role in fixing and limiting. In general use, the card plate 37 is between the mounting rod 2 and the guardrail frame 1. It is generally designed that the lower end of the guardrail frame 1 is just fitted at the bottom of the card plate 37 at this time. At this time, the guardrail frame cannot be lifted and cannot complete the subsequent rotation; once the guardrail frame needs to be rotated, the paddle 382 is moved to the right to drive the card plate 37 to withdraw from the position between the mounting rod 2 and the guardrail frame 1. At this time, the card plate 37 will not block the lower end of the opening of the guardrail frame, so the guardrail frame 1 can achieve the lifting action.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
