Description

Technical Field

[0001] This application relates to the field of robotics technology, and more specifically, to a stretcher support and fixation device for an emergency transport robot. Background Technology

[0002] With the development of robotics technology, the demand for mobile platforms such as robots to undertake material transportation tasks in scenarios such as medical rescue and emergency disaster relief is increasing. Currently, when using robots to carry stretchers, disassembly and assembly are not convenient. Existing technologies use electricity to fix the stretcher, which can affect the placement and retrieval of the stretcher if mechanical failure or power supply interruption occurs. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this application provides a stretcher support and fixation device for an emergency transport robot, which can solve the problems mentioned in the background art.

[0004] The technical solution adopted by this application embodiment to solve its technical problem is: a stretcher support and fixing device for an emergency transport robot, including a robot back plate, two square tubes arranged at the front and rear of the back plate, an ejection mechanism arranged inside the square tubes, a clamping mechanism telescopically connected to the outer end of the square tubes, a folding stretcher clamped inside the clamping mechanism, the ejection mechanism abutting against the clamping mechanism, and a check mechanism arranged on the square tubes connected to the ratchet of the clamping mechanism.

[0005] In one specific implementation, the clamping mechanism includes a rod and a collar, the outer end of the rod being fixedly connected to the collar, and the rod being inserted into the square tube.

[0006] In one specific implementation, a clamping rod is slidably connected through the insertion rod, the inner end of the clamping rod abuts against the ejection mechanism, and a clamping plate is fixedly connected to the outer end of the clamping rod, with the clamping plate located inside the collar.

[0007] In one specific implementation, the clamping mechanism further includes a spring sheet, which is attached to the inner wall of the collar. One end of the spring sheet is fixedly connected to the inner wall of the collar, and the other end of the spring sheet is rolled into a loop and slidably connected to the spring sheet itself. The spring sheet abuts against the clamping plate.

[0008] In one specific implementation, both the clamp and the movable end of the spring are fixedly connected with a retaining edge, which slides between the two ends of the spring.

[0009] In one specific implementation, the check mechanism includes a spring pin mounted on the square tube, a wedge block fixedly connected to the head of the spring pin, and an array of wedge holes adapted to the wedge block on the insert rod.

[0010] In one specific implementation, the ejection mechanism includes a push rod disposed inside the square tube, the push rod abutting against the inner end of the clamping rod.

[0011] In one specific implementation, the ejection mechanism further includes a top block, which is fixedly connected to the inner end of the top rod and slidably connected to the inner wall of the square tube. A screw is screwed onto the top block, and the screw abuts against the inner wall of the square tube.

[0012] The advantages of the embodiments of this application are:

[0013] Insert the folding stretcher into the front and rear clamping mechanisms, push the clamping mechanisms in, causing the ejection mechanism to trigger the clamping mechanisms to clamp the stretcher, and the check mechanism to prevent the clamping mechanisms from loosening. When taking the stretcher out, simply release the check mechanism. The loading and unloading operation is simple, requires no power drive, and has high reliability. Attached Figure Description

Detailed Implementation

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art above, and the overall idea is as follows:

[0020] Please see Figures 1-4A stretcher support and fixing device for an emergency transport robot includes a back plate 10 of the robot. Two square tubes 20 are arranged at the front and rear of the back plate 10. An ejection mechanism 30 is installed inside each square tube 20. A clamping mechanism 40 is telescopically connected to the outer end of each square tube 20. A folding stretcher is clamped within the clamping mechanism 40. The ejection mechanism 30 abuts against the clamping mechanism 40. A check mechanism 50 is provided on the square tube 20 and is ratchetedly connected to the clamping mechanism 40. The folding stretcher is inserted into the two clamping mechanisms 40, and the clamping mechanisms 40 are pushed in, causing the ejection mechanism 30 to trigger the clamping mechanism 40 to clamp the stretcher. The check mechanism 50 prevents the clamping mechanism 40 from loosening. When removing the stretcher, only the check mechanism 50 needs to be released. The loading and unloading operation is simple, requires no power drive, and has high reliability.

[0021] Please see Figures 1-4 The clamping mechanism 40 includes a rod 41 and a collar 42. The outer end of the rod 41 is fixedly connected to the collar 42, and the rod 41 is inserted into the square tube 20. Here, the collar 42 is used to insert the folding stretcher, and the rod 41 is used to insert into the square tube 20, serving as a connection. In this embodiment, a limit block is provided on the rod 41 so that the collar 42 can be connected to the square tube 20 without falling off, and there are only two states: clamping and releasing, thus preventing the clamping mechanism 40 from being lost.

[0022] Please see Figures 1-4 A clamping rod 43 is slidably connected through the insertion rod 41. The inner end of the clamping rod 43 abuts against the ejection mechanism 30, and a clamping plate 44 is fixedly connected to the outer end of the clamping rod 43. The clamping plate 44 is located inside the collar 42. Here, when the collar 42 is inserted inward, the clamping rod 43 remains stationary due to the support of the ejection mechanism 30. In this way, the clamping plate 44 moves relative to the collar 42, clamping and fixing the stretcher inside the collar 42.

[0023] Please see Figures 1-4 The clamping mechanism 40 also includes a spring piece 45, which fits against the inner wall of the collar 42. One end of the spring piece 45 is fixedly connected to the inner wall of the collar 42, and the other end of the spring piece 45 is rolled into a loop and slidably connected to itself. The spring piece 45 abuts against the clamping plate 44. Here, when the clamping plate 44 presses the spring piece 45 tightly, the spring piece 45 retracts to help to tightly wrap the stretcher. In this embodiment, the surface of the spring piece 45 is provided with protrusions to increase friction with the stretcher.

[0024] Please see Figures 1-4 Both the clamping plate 44 and the movable end of the spring sheet 45 are fixedly connected with baffles 46, which slide around the two ends of the spring sheet 45. Here, the baffles are used to ensure that the spring sheet 45 can only be wound and expanded inside the collar 42 without axial deformation.

[0025] Please see Figures 1-4The check mechanism 50 includes a spring pin 51, which is mounted on the square tube 20. A wedge block 52 is fixedly connected to the head of the spring pin 51, and the insertion rod 41 has a series of wedge holes that match the wedge block 52. Here, when the insertion rod 41 is inserted, a ratchet connection is formed through the wedge block 52, and the collar 42 is pushed inward by force to achieve a check on the insertion rod 41, thereby maintaining the clamped state. After the spring pin 51 is pulled up, the wedge block 52 leaves the insertion rod 41, and the restoring elasticity of the spring piece 45 pushes the collar 42 and the insertion rod 41 outward, thereby releasing the stretcher, which can then be pulled out.

[0026] Please see Figures 1-4 The ejection mechanism 30 includes an ejector rod 31, which is disposed inside the square tube 20 and abuts against the inner end of the clamping rod 43. Here, the ejector rod 31 is used to provide support for the insertion rod 41. When the insertion rod 41 and the collar 42 are pushed in, the ejector rod 31 ejects the insertion rod 41 and the clamping plate 44 to achieve a clamping effect.

[0027] Please see Figures 1-4 The ejection mechanism 30 also includes a top block 32, which is fixedly connected to the inner end of the top rod 31 and slidably connected to the inner wall of the square tube 20. A screw 33 is screwed onto the top block 32, and the screw 33 abuts against the inner wall of the square tube 20. Here, loosening the screw 33 allows the top block 32 to slide with the top rod 31, thereby adjusting the degree of ejection and determining the position of the collar 42 when it is clamped, so as to adapt to different types of folding stretchers. In this embodiment, the inner wall of the square tube 20 has multiple grooves arranged axially to facilitate the screw 33's abutment, improve the screw 33's fixing force, and prevent the top block 32 from loosening.

[0028] When using this application: fold the stretcher and insert it into the front and rear collars 42. Push the collars 42 inward. When the insertion rod 41 is inserted, it forms a ratchet connection through the wedge block 52, which prevents the insertion rod 41 from returning. At the same time, the push rod 31 pushes out the clamping rod 43. The clamping plate 44 deforms the spring piece 45 to wrap and clamp the stretcher in the collars 42, achieving quick clamping and fixation. When unloading the stretcher, pull up the spring pin 51. Under the return elasticity of the spring piece 45, the collars 42 automatically move outward, releasing the clamp on the stretcher. The stretcher can then be released. In addition, the square tube 20 can be part of the equipment support, which makes the structure more compact and easier for the robot to carry.

[0029] In summary, the folding stretcher is inserted into the front and rear clamping mechanisms 40, and the clamping mechanisms 40 are pushed in, causing the ejection mechanism 30 to trigger the clamping mechanisms 40 to clamp the stretcher. The check mechanism 50 prevents the clamping mechanisms 40 from loosening. When taking the stretcher out, it is only necessary to release the check mechanism 50. The loading and unloading operation is simple, requires no electric drive, and has high reliability.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
