[0039] like Figure 1-2 As shown, a stretcher with a built-in retractable safety belt includes: a stretcher body 1, with handles at the front and rear ends of the stretcher body 1, a flexible pad 2 fixedly connected to the upper surface of the stretcher body 1, and several pairs of strap retraction assemblies 4 on both sides of the stretcher body 1. The strap retraction assemblies 4 are fitted with restraint straps 3 inside, one end of the restraint straps 3 is engaged with the strap retraction assemblies 4, and the other ends of the two engaged restraint straps 3 are fixedly connected with a female buckle 5 and a male buckle 6, respectively.

[0040] The strap retraction assembly 4 is used to pull back the restraint strap 3, and the female buckle 5 and the male buckle 6 are fastened together.

[0041] Several strap fixing components 7 are provided on both sides of the stretcher body 1. The strap fixing components 7 cooperate with the restraint straps 3 to fix the restraint straps 3.

[0042] The strap retraction component 4 automatically pulls back the restraint strap 3, ensuring a more secure fixation of the patient on the stretcher and reducing the risk of the patient slipping or being injured during transport due to bumps or unexpected situations. The strap retraction component 4 also makes the adjustment and fixation of the restraint strap 3 faster and more convenient, allowing medical staff to focus more on patient care and emergency work. The combined use of the female buckle 5 and male buckle 6 makes the connection of the restraint strap 3 more convenient and reliable, reducing the complexity of manual operation and improving the safety of fixation. The telescopic design of the restraint strap 3 allows the stretcher to adapt to patients of different body types and weights, providing effective fixation and protection for both adults and children. The strap fixation component 7 allows the restraint strap to be fixed in various ways according to the specific situation of the patient, increasing the applicability and flexibility of the stretcher.

[0043] like Figure 1 As shown, an anti-slip pad 8 is fitted on the outer side wall of the handle, and a limit bolt 9 is threadedly connected to the end of the handle. The limit bolt 9 is used to prevent the anti-slip pad 8 from falling off the handle.

[0044] The anti-slip mat 8 increases friction between the handle and the operator's hand, especially in wet, sweaty, or liquid conditions. It effectively prevents the hand from slipping during operation. This is particularly important for medical personnel carrying stretchers, especially in emergencies, as it can prevent accidents caused by slippage. The anti-slip mat 8 also provides a better grip, reducing hand discomfort and fatigue during prolonged handling. This helps improve the efficiency of medical personnel and reduces the risk of hand injuries caused by prolonged operation.

[0045] The limiting bolt 9 is designed to prevent the anti-slip pad 8 from accidentally falling off the handle. This design ensures that the anti-slip pad 8 is always firmly fixed to the handle during use, preventing it from loosening or falling off during emergency handling, thus ensuring the safety and stability of operation.

[0046] like Figure 2-3 As shown, the strap retraction assembly 4 includes: a mounting box 401, which is fixedly connected to the lower surface of the stretcher body 1. A rotating shaft 402 is rotatably connected inside the mounting box 401. A winch 403 is provided on the rotating shaft 402. The winch 403 rotates coaxially with the rotating shaft 402. One end of the restraint strap 3 is fixedly connected to the winch 403. The winch 403 is used to wind the restraint strap 3.

[0047] A spring-loaded cavity 405 is provided on one side of the mounting box 401, and a spring-loaded spring is installed inside the spring-loaded cavity 405. The rotating shaft 402 extends into the spring-loaded cavity 405 and cooperates with the spring-loaded spring. When the restraint strap 3 is not pulled, the spring-loaded spring drives the winch 403 to rotate and retract the restraint strap 3. Compared with other stretchers with external restraints, this application has the restraint strap built in, which can be flexibly pulled out when needed, effectively improving the work efficiency of medical staff and avoiding the situation of external restraints becoming messy or knotted.

[0048] like Figure 2-3 As shown, a reinforcing plate 404 is provided between the side wall of the mounting box 401 near the stretcher body 1 and the lower surface of the stretcher body 1. In use, the mounting box 401 sometimes needs to be in direct contact with the ground; the reinforcing plate 404 effectively enhances its load-bearing capacity.

[0049] like Figure 4-5 As shown, the strap fixing assembly 7 includes: a pair of rotating seats 701, the rotating seats 701 being fixedly connected to the side wall of the stretcher body 1, and the two rotating seats 701 being distributed on both sides of the restraint strap 3;

[0050] Cam rods 702 are rotatably connected to the two rotating seats 701. One end of the cam rod 702 extends out of the rotating seat 701 and is fixedly connected to a rotating handle 703. The restraint strap 3 is located between the cam rod 702 and the stretcher body 1. When it is necessary to clamp the restraint strap 3, rotating the rotating handle 703 will clamp the restraint strap 3 with the larger diameter part of the cam rod 702. Since the recoil force provided by the spring is limited, when encountering a heavy patient, the strap fixation assembly 7 is needed to further fix the patient.

[0051] like Figure 6-7 As shown, the female buckle 5 includes: a buckle housing 501 fixedly connected to the restraint strap 3, the upper surface of the buckle housing 501 is open, the inner cavity of the buckle housing 501 is slidably connected with a pressing block 502, a first spring 504 is provided between the lower surface of the pressing block 502 and the bottom surface of the inner cavity of the buckle housing 501, and a snap-fit ​​block 503 is provided on the side of the pressing block 502 adjacent to the male buckle 6;

[0052] The buckle 6 includes: a connecting plate 601 fixedly connected to the restraint strap 3, an insert plate 602 fixedly connected to one end of the connecting plate 601 away from the restraint strap 3, a snap-fit ​​groove 603 on the insert plate 602, and an clearance opening for inserting the insert plate 602 on the buckle housing 501.

[0053] The snap-fit ​​slot 603 engages with the snap-fit ​​block 503.

[0054] In practical use, insert the insert plate 602 into the clearance opening so that the snap-fit ​​groove 603 and the snap-fit ​​block 503 cooperate to complete the engagement of the female snap-fit ​​5 and the male snap-fit ​​6; when it is necessary to separate the two, press the pressing block 502 so that the snap-fit ​​block 503 disengages from the snap-fit ​​groove 603, and the female snap-fit ​​5 and the male snap-fit ​​6 can be separated.

[0055] like Figure 6-7 As shown, a clamping block 505 is slidably connected to the snap-fit ​​housing 501. One side of the clamping block 505 engages with the insert plate 602, and the other side is fixedly connected to one end of a second spring 506. The other end of the second spring 506 is fixedly connected to the inner cavity sidewall of the snap-fit ​​housing 501. The clamping block 505 provides an auxiliary clamping force to the insert plate 602 when it engages with the snap-fit ​​block 503, preventing the insert plate 602 from accidentally detaching from the snap-fit ​​block 503 due to vibration or other reasons.

[0056] like Figure 6-7 As shown, the side of the latching block 503 adjacent to the insert plate 602 is an inclined transition surface. Because of this transition surface, when the insert plate 602 is inserted, the latching block 503 and the latching slot 603 can be engaged without pressing the pressing block 502.

[0057] In one specific embodiment, the surface of the restraint strap 3 is provided with a plurality of Velcro straps.

[0058] In practical use, when the patient's condition is more serious, it may be necessary to use it in conjunction with other medical devices. The Velcro straps can help to fix other medical devices in place.

[0059] like Figure 8 As shown, in another specific embodiment of this application, a telescopic rod 10 is provided at the handle of the stretcher body 1. The outer end of the telescopic rod 10 is fitted with an anti-slip pad 8 and threadedly connected with a limit bolt 9. The telescopic rod 10 allows for easy adjustment of the handle's length, thus adapting to different usage habits of medical staff.

[0060] The front and rear ends of the stretcher body 1 are rotatably connected to rotating plates 11 via rotating seats 12. When the rotating plates 11 are in the open state, they are fixed to the back of the stretcher body 1 via locking plates 13. The front of the rotating plates 11 is also provided with an anti-slip layer. The rotating plates 11 make it easy to adjust the size of the stretcher body 1 according to the patient's specific height, thus improving its applicability.

[0061] 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.
