[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.
[0034] like Figure 1-2 and Figure 5 As shown, a stretcher with adjustable guardrails includes: a stretcher plate 1, with handles on the front and rear sides of the stretcher plate 1, and guardrail assemblies 2 on the left and right sides of the stretcher plate 1. The guardrail assemblies 2 are rotatably connected to the stretcher plate 1 via rotating seats 3. The stretcher plate 1 has a mounting groove 101 for mounting the rotating seats 3, and a rotating seat 3 is fixedly connected to the opposite side wall of the mounting groove 101.
[0035] The guardrail assembly 2 includes: at least two rotating plates 201, the rotating plates 201 being rotatably connected to the rotating seat 3, and a plurality of protective rods 202 being fixedly connected between the rotating plates 201 and on the outer sides of the rotating plates 201 at both ends, the protective rods 202 being horizontally spaced apart, and the ends of the outer protective rods 202 being fixedly connected to connecting plates 203.
[0036] The lower part of the stretcher plate 1 is provided with locking bolts 10 for locking the rotating plate 201.
[0037] By installing rotatable guardrail assemblies 2 on the left and right sides of the stretcher board 1 and connecting them to the stretcher board via rotating seats 3, the angle of the guardrails can be adjusted, increasing the flexibility of use. The angle of the guardrail assembly 2 can be flexibly adjusted according to the patient's body size. When the patient is relatively small, the guardrail assembly 2 is in a vertical position to prevent the patient from moving and to facilitate the patient's arm hanging down. When the patient is larger, the guardrail assembly 2 can be lowered as an extension of the stretcher board 1, providing stable support for the patient and improving patient comfort. At the same time, the guardrail assembly 2 consists of multiple rotating plates 201, which are connected to each other and at both ends by protective rods 202 to form a stable protective structure. The ends of the outer protective rods 202 are fixed with connecting plates 203 to improve the stability of the protective rods 202. The position of the rotating plates 201 is locked by locking bolts 10 located at the bottom of the stretcher board 1 to ensure that the guardrail assembly 2 will not move accidentally during use, improving the safety of use. After adjusting the angle of the guardrail assembly 2, medical staff can lock it with locking bolts 10.
[0038] like Figure 2-3As shown, the rotating plate 201 includes: a rotating shaft 2013, both ends of which are rotatably connected to the rotating seat 3; an mounting plate 2011 is provided on the upper part of the rotating shaft 2013, which is used to cooperate with the protective rod 202; and a limiting plate 2012 is provided on the lower part of the rotating shaft 2013, which is used to abut against the lower surface of the stretcher plate 1 to limit the maximum rotation angle of the rotating plate 201.
[0039] The limiting plate 2012 ensures that the rotating plate 201 can only rotate within a set angle range, preventing the guardrail assembly 2 from over-expanding and losing its load-bearing capacity when it is in the lowered state and bearing the weight of the patient, thus enhancing the reliability and safety of the guardrail assembly 2.
[0040] like Figure 4 As shown, the rotating seat 3 includes: a fixed sleeve 301, the inner cavity of the fixed sleeve 301 is hollow, and the middle part of the vertical side wall is rotatably connected to the rotating shaft 2013. A number of semi-circular protrusions 302 are evenly distributed on the circumferential side wall of the inner cavity of the fixed sleeve 301.
[0041] The rotating shaft 2013 is fitted with a rotating sleeve 303 in the inner cavity of the fixed sleeve 301. The rotating sleeve 303 rotates coaxially with the rotating shaft 2013. Several telescopic tubes 304 are evenly distributed on the outer circumferential sidewall of the rotating sleeve 303. The telescopic tubes 304 are hollow inside, and a positioning top bead 305 is engaged at the end of the telescopic tube 304. A support spring 306 is provided between the positioning top bead 305 and the bottom of the inner cavity of the telescopic tube 304.
[0042] The positioning top bead 305 cooperates with the semi-circular protrusion 302 to adjust the rotation angle of the rotating shaft 2013.
[0043] The semi-circular protrusions 302 evenly distributed on the inner circumferential side wall of the fixed sleeve 301 cooperate with the positioning top bead 305 at the end of the telescopic tube 304 to realize multi-position positioning of the rotating plate 201. In this way, medical staff can adjust the angle of the rotating plate 201 through simple operation to meet the needs of different usage occasions.
[0044] The function of the support spring 306 is to maintain close contact between the positioning ball 305 and the semi-circular protrusion 302, so that the rotating plate 201 can abut against each other when adjusted to the required angle. When the angle needs to be adjusted, simply apply a certain force to rotate the rotating plate 201, causing the positioning ball 305 to temporarily disengage from the semi-circular protrusion 302. After rotating to the new position, the positioning ball 305 will re-engage with the corresponding semi-circular protrusion 302. The whole process is very simple.
[0045] In one specific embodiment, one end of the rotating shaft 2013 extends into the interior of the stretcher plate 1, such as... Figure 5 As shown, the stretcher plate 1 is provided with a locking bolt 10 corresponding to the rotating shaft 2013. The locking bolt 10 is threadedly connected to the stretcher plate 1, and its end cooperates with the rotating shaft 2013.
[0046] When it is necessary to limit the guardrail assembly 2, rotate the locking bolt 10 so that the end of the locking bolt 10 abuts against the rotating shaft 2013. Preferably, the outer end of the locking bolt 10 is provided with an extension rod, which makes it easier for medical staff to rotate and saves more effort.
[0047] like Figure 1 As shown, the handle is fitted with an anti-slip pad 6, and the end of the handle is threadedly connected to a limiting bolt 7. The anti-slip pad 6 increases the friction between the hand and the handle, preventing the hand from slipping when carrying a stretcher, especially when the hands are sweaty or slippery, thus improving the stability and safety of operation. The limiting bolt 7 fixes the position of the anti-slip pad 6, preventing it from shifting or falling off under external force, ensuring that the anti-slip pad 6 is always in the correct position and performs its anti-slip function.
[0048] like Figure 1 and Figure 6 As shown, the stretcher plate 1 is arc-shaped, and a plurality of reinforcing plates 8 are provided on the lower surface of the stretcher plate 1. The lower surface of the reinforcing plates 8 is horizontally arranged.
[0049] like Figure 1 and Figure 6 As shown, connecting rings 9 are rotatably connected to both sides of the reinforcing plate 8. One end of an elastic strap 4 is fixedly connected to the connecting ring 9, and the other end of the elastic strap 4 is fixedly connected to a connecting buckle 5. The connecting buckles 5 on the corresponding elastic straps 4 cooperate with each other.
[0050] The reinforcing plate 8 increases the rigidity of the overall stretcher structure, ensuring sufficient support when the patient needs to be lifted. The elastic bandage 4 is fixed to the reinforcing plate 8 by the connecting ring 9, and the other end is connected by the connecting buckle 5. The connecting ring 9 can reduce the friction between the end of the elastic bandage 4 and the connection point, extending its service life. The connecting buckle 5 can be a conventional bandage connecting buckle, and the specific structure will not be described in detail here.
[0051] like Figure 7 As shown, in another specific embodiment of this application, a telescopic rod 14 is provided at the handle of the stretcher plate 1. The outer end of the telescopic rod 14 is fitted with an anti-slip pad 6 and threadedly connected with a limit bolt 7. The telescopic rod 14 allows for easy adjustment of the handle's length, thus adapting to different usage habits of medical staff.
[0052] The front and rear ends of the stretcher board 1 are rotatably connected to the rotating plate 11 via the rotating seat 12. When the rotating plate 11 is in the open state, it is fixed to the back of the stretcher board via the locking plate 13. The front of the rotating plate 11 is also provided with an anti-slip layer. The rotating plate 11 allows for easy adjustment of the size of the stretcher board 1, making it convenient to adjust the size of the stretcher board 1 according to the patient's specific height, thus improving its applicability.
[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
