DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] like Figure 1 、 Figure 2 、 Figure 3As shown, a structural diagram of an active buffering surgical platform for a cabin vehicle or an ambulance provided by an embodiment of the present invention includes a base 1, a surface of the base 1 is provided with multiple groups of support rods 11, the tops of the multiple groups of support rods 11 are fixedly connected to a workbench 2, a surface of the workbench 2 is provided with a placement cavity 21, the two ends of the placement cavity 21 are connected, and two groups of relatively distributed supporting plates 4 are slidably installed in the placement cavity 21 along the horizontal direction, a stretcher plate 3 is placed above the two groups of supporting plates 4, and a positioning mechanism 5 that cooperates with the stretcher plate 3 is provided on the surface of the supporting plate 4, and the positioning mechanism 5 includes a disassembly assembly 51 and a buffer assembly 5. 2. The disassembly and assembly component 51 includes a clamping portion 511 and an adjusting portion 512. The clamping portion 511 is located on the bottom wall of the stretcher board 3 and is connected to the load-bearing plate 4. The clamping portion 511 is used to fix the stretcher board 3 on the surfaces of the two groups of load-bearing plates 4. The adjusting portion 512 is located in the stretcher board 3 and is connected to the clamping portion 511. The adjusting portion 512 controls the separation of the stretcher board 3 and the load-bearing plate 4 by cooperating with the clamping portion 511. The buffer component 52 is located in the placement cavity 21 and is connected to the load-bearing plate 4. The buffer component 52 is used to reduce the inertial force of the load-bearing plate 4 and the stretcher board 3 in the placement cavity 21.

[0024] Initially, within the placement chamber 21, the clamping portion 511 secures the stretcher board 3 to the surface of the support plate 4. When a patient outside the shelter vehicle needs to be rescued, the adjustment portion 512 cooperates with the clamping portion 511 to release the restraints on the support plate 4, allowing staff to conveniently lift the stretcher board 3 outside the shelter vehicle for rescue. Once the patient is lying on the stretcher board 3, the stretcher board 3 is carried into the placement chamber 21, where the clamping portion 511 conveniently secures the stretcher board 3 to the surface of the support plate 4. During stable travel of the shelter vehicle, the buffer assembly 52 positions the support plate 4 within the placement chamber 21, preventing the stretcher board 3 from vibrating violently. When the shelter vehicle experiences sudden acceleration or deceleration during travel, the buffer assembly 52 within the placement chamber 21 effectively mitigates the inertial impact on the support plate 4, thereby simultaneously mitigating the inertial impact on the stretcher board 3 and effectively improving the stability of the stretcher board 3 on the workbench 2.

[0025] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, as a preferred embodiment of the present invention, the clamping portion 511 includes two groups of relatively distributed positioning holes 5111 opened on the surface of the supporting plate 4, and the bottom wall of the stretcher plate 3 is fixedly installed with multiple groups of positioning columns 5112 that cooperate with the positioning holes 5111. The side walls of the positioning columns 5112 are provided with multiple groups of annularly distributed telescopic grooves 5113, and a clamping block 5115 is slidably installed in the telescopic groove 5113. One end of the clamping block 5115 is set to a slope structure and extends to the outside of the positioning column 5112. An extrusion spring 5114 is fixedly installed in the telescopic groove 5113, and the telescopic end of the extrusion spring 5114 is connected to the clamping block 5115.

[0026] After the patient lies on the surface of the stretcher board 3, the stretcher board 3 is carried into the placement cavity 21 and the positioning posts 5112 on the bottom wall of the stretcher board 3 are aligned with the positioning holes 5111 on the surface of the support plate 4. The positioning posts 5112 are inserted into the positioning holes 5111. At this time, the clamping block 5115 moves to the bottom of the support plate 4. The clamping block 5115 and the positioning holes 5111 cooperate with each other to stably fix the stretcher board 3 on the surface of the support plate 4. When the stretcher board 3 needs to be disassembled, the adjustment portion 512 controls the clamping block 5115 to move as a whole into the telescopic slot 5113. The positioning posts 5112 can move freely in the vertical direction within the positioning holes 5111. The clamping block 5115 does not interfere with the movement of the positioning posts 5112. The staff can conveniently carry the stretcher board 3 to the outside of the placement cavity 21.

[0027] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 As shown, as a preferred embodiment of the present invention, the adjusting portion 512 includes a horizontal hole 5121 opened on the side wall of the stretcher board 3 and located directly above the positioning column 5112, a control spring 5124 is fixedly installed in the horizontal hole 5121, a control column 5123 is slidably installed in the horizontal hole 5121, the telescopic end of the control spring 5124 is connected to the control column 5123, one end of the control column 5123 extends to the outside of the stretcher board 3, and a wire groove 5122 is downwardly opened on the bottom wall of the horizontal hole 5121, which extends into the positioning column 5112 and is connected to the telescopic slot 5113, and a pulling rope 5125 is fixedly installed on one end of the clamping block 5115 located in the telescopic slot 5113, and the pulling rope 5125 away from the clamping block 5115 extends through the wire groove 5122 into the horizontal hole 5121 and is connected to the control column 5123.

[0028] When the stretcher plate 3 needs to be disassembled from the bearing plate 4, the staff presses the control column 5123 at the side wall of the stretcher plate 3, and then pushes the control column 5123 to move into the horizontal hole 5121, and when the control column 5123 moves in the horizontal hole 5121, the pulling rope 5125 is pulled to move synchronously, the clamping block 5115 is pulled to move into the telescopic groove 5113, and after the clamping block 5115 moves into the telescopic groove 5113, the positioning column 5112 can be freely moved in the positioning hole 5111 in the vertical direction, and the clamping block 5115 does not interfere with the movement of the positioning column 5112, so that the staff can conveniently lift the stretcher plate 3 to the outside of the placement cavity 21.

[0029] As shown in Figure 1 、 Figure 2 、 Figure 3 As a preferred embodiment of the present application, the buffer assembly 52 includes a buffer block 521 slidingly installed in the placement cavity 21 in the horizontal direction, the buffer block 521 is located below the bearing plate 4, the placement cavity 21 is rotatably installed with a rotating column 522 at both ends, the rotating column 522 is fixedly installed with a guide wheel 523 on the surface, one side wall of the buffer block 521 is fixedly installed with a first buffer rope 524, one end of the first buffer rope 524 away from the buffer block 521 passes through the guide wheel 523 on one side and is connected with a group of bearing plates 4, the other side wall of the buffer block 521 is fixedly installed with a second buffer rope 525, one end of the second buffer rope 525 away from the buffer block 521 passes through the guide wheel 523 on the other side and is connected with another group of bearing plates 4, the placement cavity 21 is fixedly installed with a baffle 526 at both ends, the baffle 526 is fixedly installed with a buffer spring 527 on the side wall, and the telescopic end of the buffer spring 527 is connected with the buffer block 521.

[0030] Initially, multiple groups of buffer springs 527 apply thrust to the buffer block 521 from both sides in the placement chamber 21, and the buffer block 521 is stably located in the middle of the placement chamber 21. When the container vehicle accelerates urgently, under the action of inertia, the buffer block 521 generates an inertial force toward one side in the placement chamber 21. When the buffer block 521 moves toward one side in the placement chamber 21, the first buffer rope 524 on one side of the buffer block 521 is in a stretched state, and the second buffer rope 525 is in a relaxed state. The first buffer rope 524 cooperates with the guide wheel 523 to apply a pulling force toward the other side to the stretcher board 3 in the placement chamber 21. The pulling force of the first buffer rope 524 is opposite to the inertial force acting on the stretcher board 3, which can effectively improve the stability of the stretcher board 3 in the placement chamber 21. When the container truck accelerates urgently, under the action of inertia, the buffer block 521 generates an inertial force toward the other side in the placement cavity 21. When the buffer block 521 moves toward the other side in the placement cavity 21, the first buffer rope 524 on one side of the buffer block 521 is in a relaxed state, and the second buffer rope 525 is in a stretched state. The second buffer rope 525 cooperates with the guide wheel 523 to apply a pulling force toward the other side to the stretcher board 3 in the placement cavity 21. The pulling force of the second buffer rope 525 is opposite to the direction of the inertial force acting on the stretcher board 3, which can effectively improve the stability of the stretcher board 3 in the placement cavity 21.

[0031] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, a damper 6 is provided in the base 1 , and the damper 6 is connected to the bottom end of the support rod 11 .

[0032] During use, the damper 6 and the support rod 11 cooperate with each other to effectively improve the anti-vibration effect of the workbench 2.

[0033] like Figure 3 As shown in the figure, as a preferred embodiment of the present invention, the receiving cavity 21 is fixedly mounted with a barrier rod 7 at each end. The two sets of barrier rods 7 are jointly fixedly mounted with a first limiting rod 8. The first limiting rod 8 is horizontally slidably connected to the supporting plate 4. The supporting plate 4 slides along the surface of the first limiting rod 8, which can effectively improve the stability of the supporting plate 4.

[0034] like Figure 3 As shown in FIG. 1 , as a preferred embodiment of the present invention, a second limiting rod 9 is fixedly mounted on the bottom of the placement cavity 21. The second limiting rod 9 is horizontally slidably connected to the buffer block 521. The second limiting rod 9 can effectively improve the stability of the buffer block 521 when it moves within the placement cavity 21.

[0035] The working principle of the present invention is: initially in the placement cavity 21, the positioning column 5112 is inserted into the positioning hole 5111, at this time the clamping block 5115 moves to the bottom of the supporting plate 4, and the clamping block 5115 and the positioning hole 5111 cooperate with each other to stably fix the stretcher board 3 on the surface of the supporting plate 4. When it is necessary to rescue a patient outside the cabin vehicle, the staff presses the control column 5123 on the side wall of the stretcher board 3 and pushes the control column 5123 to move toward the horizontal hole 5121. When the control column 5123 moves in the horizontal hole 5121, it pulls the pulling rope 5125 to move synchronously. The pulling rope 5125 pulls the clamping block 5115 to move toward the telescopic groove 5113. After the clamping block 5115 moves as a whole into the telescopic groove 5113, the positioning column 5112 can move freely in the positioning hole 5111 along the vertical direction. The clamping block 5115 will not interfere with the movement process of the positioning column 5112. The staff can easily lift the stretcher board 3 to the outside of the placement cavity 21. After the patient lies on the surface of the stretcher board 3, the stretcher board 3 is lifted and transported into the placement cavity 21 and the positioning column 5112 on the bottom wall of the stretcher board 3 is aligned with the positioning hole 5111 on the surface of the supporting plate 4. The positioning column 5112 is inserted into the positioning hole 5111. At this time, the clamping block 5115 moves to the bottom of the supporting plate 4, and the clamping block 5115 and the positioning hole 5111 cooperate with each other to stably fix the stretcher board 3 on the surface of the supporting plate 4.

[0036] Multiple groups of buffer springs 527 apply thrust to the buffer block 521 from both sides in the placement chamber 21, and the buffer block 521 is stably located in the middle of the placement chamber 21. When the container vehicle accelerates urgently, under the action of inertia, the buffer block 521 generates an inertial force toward one side in the placement chamber 21. When the buffer block 521 moves toward one side in the placement chamber 21, the first buffer rope 524 on one side of the buffer block 521 is in a stretched state, and the second buffer rope 525 is in a relaxed state. The first buffer rope 524 cooperates with the guide wheel 523 to apply a pulling force toward the other side to the stretcher board 3 in the placement chamber 21. The pulling force of the first buffer rope 524 is opposite to the inertial force acting on the stretcher board 3, which can effectively improve the stability of the stretcher board 3 in the placement chamber 21. When the container truck accelerates urgently, under the action of inertia, the buffer block 521 generates an inertial force toward the other side in the placement cavity 21. When the buffer block 521 moves toward the other side in the placement cavity 21, the first buffer rope 524 on one side of the buffer block 521 is in a relaxed state, and the second buffer rope 525 is in a stretched state. The second buffer rope 525 cooperates with the guide wheel 523 to apply a pulling force toward the other side to the stretcher board 3 in the placement cavity 21. The pulling force of the second buffer rope 525 is opposite to the direction of the inertial force acting on the stretcher board 3, which can effectively improve the stability of the stretcher board 3 in the placement cavity 21.

[0037] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
