Description

Technical Field

[0001] The utility model relates to the technical field of rescue stretchers, in particular to a multifunctional rescue stretcher which is convenient for rescue in complex terrains. Background Art

[0002] Combat casualty relief is the process of providing medical care and first aid services in a military environment. Ambulance stretchers are often used to transport injured or sick personnel to medical facilities or other safe locations. They are designed to firmly support patients and facilitate transportation by rescuers. Ambulance stretchers are usually required during combat casualty relief.

[0003] Some existing emergency stretchers are usually configured as an integrated pole body. When moving the stretcher in complex terrain, the entire stretcher needs to be lifted, which is troublesome. In addition, when replacing the soft cloth on the surface of this type of emergency stretcher, it is necessary to first release the fixation of the soft cloth and the pole body, and then pull the soft cloth from one end to pull it out from the surface of the pole body, which is troublesome.

[0004] Therefore, those skilled in the art provide a multifunctional rescue stretcher that is convenient for rescue in complex terrains to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a multifunctional rescue stretcher which is convenient for rescue in complex terrains. By setting a folding mechanism, the entire stretcher can be folded for transportation, which is convenient for rescue in complex terrains. By setting a disassembly mechanism, it is more convenient to replace the first soft cloth and the second soft cloth.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional rescue stretcher convenient for complex terrain rescue, comprising two folding mechanisms, two fixing mechanisms, two first soft cloths, two second soft cloths and four fixing plates, the two folding mechanisms comprising four first support plates, four second support plates, four sliding grooves, a plurality of lifting plates, four first clamping blocks and four second clamping blocks, the four first support plates are both provided with sliding blocks on opposite sides of one side end surfaces of two sides, and first return springs are fixedly provided between the four sliding blocks and the four first support plates;

[0007] The two fixing mechanisms include two fixing frames, two screw rods and two slides. The four first support plates and the four second support plates are provided with strip grooves on the end faces on the opposite sides of each other. A disassembly mechanism is provided between the inner walls on the opposite sides of the multiple strip grooves. The four disassembly mechanisms include multiple clamping plates, four connecting plates, four rotating rods and four protrusions. Second return springs are fixedly provided on the front and rear sides of the lower ends of the multiple clamping plates.

[0008] When the second support plate cannot be moved any further, the two second blocks are manually lifted upwards, and under the action of the rebound force of the first return spring, the slider returns to its original position, thereby fixing the first support plate and the second support plate together. When the two folding mechanisms are folded together, the screw rod is manually rotated to drive the card plate to leave the inner wall of the first support plate. At this time, the two folding mechanisms can be rotated from the horizontal position to the vertical state, and the rotating rod is manually pulled downwards. When the rotating rod cannot be pulled any further, the rotating rod is manually rotated. At this time, the card plate is no longer in the hard plate inner wall of the first soft cloth. At this time, the first soft cloth can be taken out, and the same operation can be performed on the second soft cloth.

[0009] Furthermore, the two first soft cloths and the two second soft cloths are respectively clamped and arranged between the plurality of strip-shaped grooves, the four fixing plates are respectively fixedly connected to the two folding mechanisms, and the middle positions of the upper surfaces of the four fixing plates are provided with circular grooves;

[0010] Through the above technical solution, by clamping the first soft cloth and the second soft cloth between the strip-shaped grooves, it is more convenient to take out the first soft cloth and the second soft cloth.

[0011] Furthermore, the four sliding grooves are respectively opened on the opposite sides of the upper end surfaces of the four first support plates, and the multiple lifting plates are respectively clamped and arranged on the inner walls of the opposite sides of the four sliding grooves, and the four second support plates are respectively rotatably connected with the multiple lifting plates in pairs;

[0012] Through the above technical solution, by pulling the slider to one side, the slider leaves the inner wall of the lifting plate, and then the second support plate can be held and moved upward, and the inner wall of the lifting plate is in the inner wall of the sliding groove to limit the lifting plate. When the lifting plate cannot move, the second lifting plate can be held and rotated.

[0013] Further, the four first clamping blocks are respectively slidably connected to the four sliders, and the four second clamping blocks are respectively slidably connected to the four sliders;

[0014] Through the above technical solution, when the slider is pulled, the second clamping block slides downward in the inner wall of the slider under the action of its own gravity. At this time, the second clamping block blocks the slider and simply fixes the slider, making it convenient to perform the remaining operations on the second support plate.

[0015] Furthermore, the two fixed frames are rotatably connected to the two folding mechanisms respectively, the two screw rods are rotatably arranged in the middle of the opposite end faces of the two fixed frames respectively, and the middle inner walls of the two slides are respectively threadedly sleeved on the opposite sides of the outer end faces of the two screw rods;

[0016] Through the above technical solution, by rotating the screw rod, the screw rod drives the clamping plate to move, and then the clamping plate leaves the inner wall of the first support plate, and the first support plate can be rotated.

[0017] Furthermore, the plurality of clamping plates are respectively slidably arranged on the upper inner walls of the plurality of strip-shaped grooves, the four connecting plates are respectively fixedly connected to the plurality of clamping plates, and the plurality of the second return springs are respectively fixedly connected to the plurality of strip-shaped grooves;

[0018] Through the above technical solution, the card plate is pushed into the inner wall of the first soft cloth and the second soft cloth hard plate by the rebound force of the second return spring, so that the first soft cloth and the second soft cloth are fixed between the strip grooves.

[0019] Furthermore, the four rotating rods are respectively rotatably arranged at the middle positions of the upper end surfaces of the four connecting plates, and the four protrusions are respectively fixedly connected to the four rotating rods;

[0020] Through the above technical solution, by pulling the rotating rod downward, the rotating rod drives the connecting plate to move downward. When the connecting plate cannot move further, the rotating rod is manually rotated. At this time, the protrusion on the surface of the rotating rod enters the inner wall of the circular groove, thereby simply fixing the rotating rod.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a multifunctional rescue stretcher which is convenient for rescue in complex terrain. At this time, the two sliders are manually pulled to the opposite sides. When the two sliders are pulled to the tail, the second block moves downward under the action of its own gravity. At this time, after releasing the pull on the slider, the slider is fixed. At this time, the second support plate is manually lifted upward. When it cannot move further, the second support plate is manually held and rotated. When the second support plate is in contact with the end surface of the first support plate, the slider is manually lifted up. At this time, under the action of the rebound force of the first return spring, the slider returns to its original position, thereby fixing the first support plate and the second support plate together. When the two folding mechanisms are folded, the screw rod is manually rotated. At this time, the two folding mechanisms can be rotated from the horizontal position to the vertical state. By setting the folding mechanism, the entire stretcher can be folded for transportation, which is convenient for rescue in complex terrain.

[0023] 2. The utility model proposes a multifunctional rescue stretcher which is convenient for rescue in complex terrain. The rotating rod is manually pulled downward. When the rotating rod cannot be pulled downward, the rotating rod is manually rotated. At this time, the protrusion on the surface of the rotating rod enters the inner wall of the circular groove, thereby fixing the rotating rod in the inner wall of the circular groove. At this time, the first soft cloth and the second soft cloth can be taken out. By setting a disassembly mechanism, it is more convenient to replace the first soft cloth and the second soft cloth. By setting this stretcher, it is easy to carry and replace the soft cloth, so that the functions of the stretcher are more diversified. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-7 The utility model provides an embodiment: a multifunctional rescue stretcher for complex terrain rescue, comprising two folding mechanisms 1, two fixing mechanisms 2, two first soft cloths 3, two second soft cloths 4 and four fixing plates 5. The two folding mechanisms 1 include four first support plates 101, four second support plates 108, four sliding grooves 102, multiple lifting plates 103, four first clamping blocks 106 and four second clamping blocks 107. The four first support plates 101 are both provided with sliding blocks 104 on opposite sides of the end surfaces of one side. A first return spring 105 is fixedly arranged between the four sliders 104 and the four first support plates 101, four sliding grooves 102 are respectively opened on the opposite side of the upper end surfaces of the four first support plates 101, and multiple lifting plates 103 are respectively clamped on the inner walls of the opposite sides of the four sliding grooves 102, four second support plates 108 are respectively rotatably connected to the multiple lifting plates 103, four first clamping blocks 106 are respectively slidably connected to the four sliders 104, and four second clamping blocks 107 are respectively slidably connected to the four sliders 104.

[0035] By manually pulling the two sliders 104 to the opposite side, when the two sliders 104 slide to the tail, the second block 107 inside the slider 104 will slide out under the action of its own gravity, then release the pull on the slider 104, under the action of the rebound force of the first return spring 105, the slider 104 is pulled backward, and the slider 104 is fixed by the abutment between the slider 104 and the inner wall of the first support plate 101, then hold the second support plate 108 and move it upward, and the lifting plate 103 is driven to move together during the movement of the second support plate 108, and the lifting plate 103 is moved during the movement. The first clamping plate 601 is driven to move upward together. When the lifting plate 103 cannot move further, the second support plate 108 is held and rotated. When the second support plate 108 is in contact with the end surface of the first support plate 101, the second clamping block 107 is manually pushed back. At this time, the slider 104 is pulled back to its original position by the rebound force of the first return spring 105. At this time, the first clamping block 106 enters into the inner wall of the second support plate 108, so that the second support plate 108 cannot rotate, and the slider 104 enters into the inner wall of the lifting plate 103, so that the lifting plate 103 cannot move downward.

[0036] The two fixing mechanisms 2 include two fixing frames 201, two screw rods 202 and two slide plates 203. The two fixing frames 201 are rotatably connected to the two folding mechanisms 1 respectively. The two screw rods 202 are respectively rotatably arranged in the middle position of the end faces of the opposite sides of the two fixing frames 201. The middle inner walls of the two slide plates 203 are respectively threadedly sleeved on the opposite sides of the outer end faces of the two screw rods 202. By rotating the screw rods 202, the screw rods 202 drive the card plate 601 to move. At this time, the card plate 601 leaves the inner wall of the first support plate 101, and the first support plate 101 can be rotated. When the two folding mechanisms 1 are rotated from the horizontal position to the vertical state, the screw rods 202 are manually turned back, and the screw rods 202 drive the card plate 601 to re-enter the inner wall of the first support plate 101, thereby fixing the first support plate 101 and the fixing frame 201 together, so that the first support plate 101 cannot rotate.

[0037] The four first support plates 101 and the four second support plates 108 are provided with strip grooves 109 on the end surfaces of the opposite sides of each other, and a disassembly mechanism 6 is provided between the inner walls of the opposite sides of the multiple strip grooves 109. The four disassembly mechanisms 6 include multiple clamping plates 601, four connecting plates 603, four rotating rods 604 and four protrusions 605. The front and rear sides of the lower ends of the multiple clamping plates 601 are fixedly provided with second return springs 602. The two first soft cloths 3 and the two second soft cloths 4 are respectively clamped and arranged between the multiple strip grooves 109. The four fixed plates 5 are respectively fixedly connected to the two folding mechanisms 1, and a circular groove 7 is opened in the middle position of the upper end surfaces of the four fixed plates 5. A plurality of clamping plates 601 are respectively slidably arranged on the upper inner walls of the plurality of strip grooves 109, and the four connecting plates 603 are respectively fixedly connected to the plurality of clamping plates 601, and a plurality of second return springs 602 are respectively fixedly connected to the plurality of strip grooves 109, and four rotating rods 604 are respectively rotatably arranged in the middle position of the upper end surfaces of the four connecting plates 603, and the four protrusions 605 are respectively fixedly connected to the four rotating rods 604.

[0038] By pulling the rotating rod 604 downward, the rotating rod 604 drives the connecting plate 603 to move downward. When the connecting plate 603 cannot move further, the rotating rod 604 is manually rotated. At this time, the protrusion 605 on the surface of the rotating rod 604 enters the inner wall of the circular groove 7, thereby simply fixing the rotating rod 604. When the rotating rod 604 moves downward, a card plate 601 is moved through the connecting plate 603, so that the card plate 601 leaves the hard plate inner wall of the first soft cloth 3 and the second soft cloth 4, and the first soft cloth 3 and the second soft cloth 4 can be taken out.

[0039] Working principle: manually pull the two sliders 104 to the opposite side, when the second block 107 slides out, release the pull on the slider 104, then hold the second support plate 108 and move it upward, when the second support plate 108 can no longer move, manually hold the second support plate 108 and rotate it, when the end surface of the second support plate 108 fits the end surface of the first support plate 101, manually push the second block 107 back, at this time the slider 104 is pulled back under the action of the first return spring 105, when After the two folding structures are folded, manually rotate the screw rod 202, and the screw rod 202 drives the card plate 601 to leave the inner wall of the first support plate 101. At this time, the two folding mechanisms 1 can be rotated. When the two folding mechanisms 1 are turned back to the vertical state, manually turn the screw rod 202 back. When taking out the first soft cloth 3 and the second soft cloth 4, manually pull the rotating rod 604 downward. When the rotating rod 604 can no longer be pulled, manually rotate the rotating rod 604, and then the first soft cloth 3 and the second soft cloth 4 can be taken out.
