[0031] 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.
[0032] Reference Figure 1 - Figure 2 , Figure 4 and Figure 5The utility model provides an embodiment: a stretcher that is easy to fix, including a mobile stretcher 1, a fixing assembly 2 is arranged on the lower surface of the mobile stretcher 1, the fixing assembly 2 includes a fixing plate 213, the fixing plate 213 is fixedly connected to the right end of the lower surface of the mobile stretcher 1, a rotating rod 21 is rotatably connected to the right surface of the fixing plate 213, a spiral groove 29 is arranged on the outer wall of the rotating rod 21, a plurality of spiral grooves 29 are arranged, and the plurality of spiral grooves 29 are symmetrically arranged, and have a certain curvature, so as to ensure that when the rotating rod 21 rotates, the plurality of circular rings 28 will move relative to or oppositely, the inner wall of the spiral groove 29 is slidably connected to a guide rod 210, and when the rotating rod 21 is rotated, the guide rod 210 will move along the spiral groove The guide rod 210 can slide on the inner wall of the spiral groove 29 through the reaction force of the spring 1 215 to reverse the rotating rod 21. The rear surface of the guide rod 210 is fixedly connected with a ring 28, and the ring 28 slides on the outer wall of the spiral groove 29. The front surface of the ring 28 is fixedly connected with a hinge block 27. The inner wall of the hinge block 27 is hinged with a connecting plate 25. The bottom end of the connecting plate 25 is hinged with a concave block 24. The lower surface of the concave block 24 is fixedly connected with a stabilizing plate 23. The lower surface of the stabilizing plate 23 is made of rubber, which increases its friction with the ground and enhances stability.
[0033] Reference Figure 1 , Figure 6 A slide rod 3 is fixedly connected to the lower surface of the mobile stretcher 1, and a sealing sleeve 4 is slidably connected to the outer wall of the slide rod 3. A roller is fixedly connected to the lower surface of the sealing sleeve 4. A piston block 5 is fixedly connected to the lower surface of the slide rod 3. The piston block 5 is connected to the inner wall of the sealing sleeve 4. An air outlet 7 is provided at the bottom end of the right surface of the sealing sleeve 4. The air outlet 7 is very small, which ensures that when the piston block 5 squeezes the air on the inner wall of the sealing sleeve 4, there will be a certain resistance, which has a buffering effect.
[0034] Reference Figure 2 , Figure 3, there are multiple groups of circular rings 28, and the multiple groups of circular rings 28 are symmetrically arranged with the center line of the stabilizing plate 23 as the symmetry axis. The outer wall of the rotating rod 21 is sleeved with a spring 215. The spring 215 always pushes the multiple groups of circular rings 28 to both ends through its own elasticity, ensuring that when the rectangular plate 211 is released from the limit plate 22, it will move the circular rings 28 to reset through its own reaction force. One end of the spring 215 is fixedly connected to the right surface of the circular ring 28, and the other end of the spring 215 is fixedly connected to the left surface of the multiple groups of circular rings 28. The upper surface of the circular ring 28 is fixedly connected with a trapezoidal slider 26 The trapezoidal slider 26 is trapezoidal in shape, and the upper surface is wider than the lower surface, ensuring that the ring 28 will not fall off and ensuring the stability of the connection. A slide groove 214 is provided on the lower surface of the mobile stretcher 1, and the upper surface of the trapezoidal slider 26 is slidably connected to the inner wall of the slide groove 214. The right surface of the rotating rod 21 is fixedly connected to the limiting plate 22, and the right surface of the fixed plate 213 is fixedly connected to the upper part of the rotating rod 21. The inner wall of the connecting block 212 is hinged with a rectangular plate 211. The outer wall of the limiting plate 22 is provided with through grooves 216, and there are multiple groups of through grooves, and the right end of the rectangular plate 211 contacts the inner wall of the through groove 216.
[0035] Reference Figure 6 The outer wall of the slide rod 3 is sleeved with a spring 26, which has a certain elasticity. When the mobile stretcher 1 is bumped, the spring 26 will buffer the impact of the bump through its own elasticity. One end of the spring 26 is fixedly connected to the upper surface of the piston block 5, and the other end of the spring 26 is fixedly connected to the inner wall of the sealing sleeve 4.
[0036] Working principle: When the mobile stretcher 1 needs to be parked aside and the roller needs to be fixed, the rectangular plate 211 only needs to be pushed upwards, and the rectangular plate 211 will rotate with the hinge between the rectangular plate 211 and the connecting block 212 as the center of the circle until the right end of the rectangular plate 211 completely leaves the inner wall of the through groove 216. At this time, the limit plate 22 can be rotated, and the limit plate 22 will drive the rotating rod 21 to rotate. At this time, the guide rod 210 will slide on the inner wall of the spiral groove 29, and the guide rod 210 will move horizontally following the arc of the spiral groove 29. At this time, the multiple groups of rings 2 8 will move relative to the guide rod 210, and at the same time, the multiple groups of rings 28 will squeeze the spring 1 215, and the ring 28 will drive the hinge block 27 to move. At this time, the hinge block 27 will rotate with the top of the connecting plate 25, so that the connecting plate 25 slowly tends to a vertical state, and the bottom end of the connecting plate 25 will rotate with the concave block 24, and drive the stabilizing plate 23 to move downward until the stabilizing plate 23 contacts the ground and the roller cannot move. At this time, the rectangular plate 211 can be turned back to limit the limiting plate 22, so that the mobile stretcher 1 can be fixed quickly and conveniently.
[0037] When it is necessary to move, it is only necessary to release the restriction of the rectangular plate 211 on the restriction plate 22. At this time, the spring 1 215 will push the ring 28 to move through its own elasticity, so that the multiple groups of rings 28 are separated. At this time, the ring 28 will drive the guide rod 210 to slide on the inner wall of the spiral groove 29, and the rotating rod 21 will also reverse accordingly. The subsequent structural matching method is the same as above, so that the stabilizing plate 23 can be kept away from the ground.
[0038] When the mobile stretcher 1 moves, if it encounters a bumpy road section, the mobile stretcher 1 will drive the slide bar 3 to slide on the inner wall of the sealing sleeve 4, and at the same time drive the piston block 5 to do piston movement on the inner wall of the sealing sleeve 4. The sealing sleeve 4 will inhale the outside air into the inner wall of the sealing sleeve 4 through the air outlet 7 and then expel it. Since the air outlet 7 is relatively small, there is a certain resistance during the expulsion, which plays a buffering role. At the same time, the spring 2 6 will also buffer the impact caused by the bumpy road section through its own elasticity, thereby enhancing the buffering effect.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
