DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] In one embodiment, see Figure 1 and Figure 2, a gas filling control device for an inflatable bottle for a rescue lifting air cushion, comprising a connecting pipe 4, the ends of the connecting pipe 4 are closed, one end of the connecting pipe 4 is connected to an air inlet 1, and the other end is connected to an air outlet 2, a connecting block 5 is integrally formed on the outside of the connecting pipe 4, wherein a valve core 3 is provided inside the connecting pipe 4, and the diameter of the valve core 3 is the same as the inner diameter of the connecting pipe 4, a rotating rod 7 is fixedly connected to the top of the valve core 3, the rotating rod 7 passes through the connecting pipe 4 and extends to the inside of the connecting block 5, one end of the rotating rod 7 located inside the connecting block 5 is connected to a torsion spring 8, and the other end of the torsion spring 8 is connected to the inner wall of the connecting block 5, a driving mechanism and a self-locking mechanism are provided inside the connecting block 5, when the lifting air cushion is inflated, the driving mechanism is used to drive the rotating rod 7 to rotate, so that the valve core 3 blocks the connecting pipe 4, and when the valve core 3 completes the blocking of the connecting pipe 4, the self-locking mechanism is used to fix the rotating rod 7.

[0025] In the present embodiment, when the inflation control device is in use, the air inlet 1 is connected to the air outlet end on the inflation bottle, and the air outlet 2 is connected to the air inlet end on the lifting air cushion. After the connection is completed, the inflation bottle inflates the interior of the lifting air cushion through the connecting pipe 4. Initially, the valve core 3 inside the connecting pipe 4 is parallel to the connecting pipe 4, and the inflation bottle and the lifting air cushion are in a connected state. The gas inside the inflation bottle can enter the interior of the lifting air cushion through the connecting pipe 4. When the lifting air cushion is inflated, the driving mechanism inside the connecting block 5 automatically drives the rotating rod 7 to rotate, and the rotating rod 7 drives the valve core 3 to rotate. When the valve core 3 is perpendicular to the connecting pipe 4, the self-locking mechanism inside the connecting block 5 automatically locks the rotating rod 7 is fixed, at this time the valve core 3 has a blocking effect on the connecting pipe 4, the connecting pipe 4 is in a closed state, the gas inside the inflation bottle cannot enter the lifting air cushion through the connecting pipe 4, through this design, an inflation control purpose is achieved, which can effectively avoid the phenomenon that when the lifting air cushion is fully inflated, the inflation bottle continues to inflate the inside of the lifting air cushion, causing the lifting air cushion to exceed the fatigue limit, ensure the expansion degree of the lifting air cushion, and improve the service life of the lifting air cushion. When the device is used up, the connecting pipe 4 is removed, and the self-locking mechanism is released at the same time. The fixing of the rotating rod 7, the rotating rod 7 and the valve core 3 are automatically reset under the action of the torsion spring 8, which is convenient for next use.

[0026] See also Figure 2 and Figure 3 The driving mechanism includes a push plate 9 fixed to the outside of the rotating rod 7, and a movable rod 17 is provided inside the connecting block 5. One end of the movable rod 17 is connected to the side of the push plate 9 in abutment with each other, and the other end of the movable rod 17 is connected to a pneumatic component. When the lifting air cushion is inflated, the pneumatic component pushes the push plate 9 through the movable rod 17, thereby causing the rotating rod 7 to rotate, wherein the movable rod 17 is also connected to the connecting block 5 through a buffer component, and the buffer component is used for elastic support of the movable rod 17;

[0027] When the lifting air cushion is fully inflated, the inflation bottle may also inflate air into the interior of the lifting air cushion through the connecting pipe 4. At this time, when the gas passes through the inside of the connecting pipe 4, it will trigger the operation of the air pressure component. The air pressure component drives the movable rod 17 to move, so that the movable rod 17 pushes the side of the push plate 9, and the push plate 9 drives the rotating rod 7 to rotate, thereby driving the valve core 3 to seal the connecting pipe 4, thereby preventing the gas from continuously entering the interior of the lifting air cushion and ensuring the expansion degree of the lifting air cushion. When the device is used up, the buffer component can reset the movable rod 17, and then reset the rotating rod 7.

[0028] See also Figure 2 and Figure 3 The pneumatic assembly includes an air cavity 11 arranged inside the connecting block 5, the air cavity 11 is communicated with the connecting pipe 4, a first piston 12 is slidably connected inside the air cavity 11, a hollow tube 21 is provided inside the connecting block 5, the hollow tube 21 is fixedly connected to the inner wall of the connecting block 5, a second piston 16 is slidably connected inside the hollow tube 21, the second piston 16 is fixedly connected to the movable rod 17, wherein the hollow tube 21 is communicated with the air pipe 10, and the other end of the air pipe 10 is communicated with the air cavity 11;

[0029] When the lifting air cushion is fully inflated, the inflation bottle may also inflate the lifting air cushion through the connecting pipe 4. At this time, the gas will enter the air cavity 11, thereby pushing the first piston 12. The first piston 12 squeezes the gas inside the air cavity 11. The gas inside the air cavity 11 enters the hollow tube 21 through the air pipe 10. The air pressure inside the hollow tube 21 increases, pushing the second piston 16. The second piston 16 drives the movable rod 17 to move, so that the movable rod 17 can push the push plate 9, causing the rotating rod 7 to rotate. Through this design, the connecting pipe 4 can be automatically blocked, thereby avoiding the phenomenon that the inflation bottle continues to inflate the lifting air cushion through the connecting pipe 4 after the lifting air cushion is fully inflated. In order to ensure the stability of the first piston 12, the inner wall of the air cavity 11 is fixed with symmetrically distributed blocks 13 that support the first piston 12.

[0030] It should be noted that in order for the valve core 3 to seal the connecting pipe 4 in time after the lifting air cushion reaches the fatigue limit, and in order to avoid the phenomenon that the valve core 3 starts to seal the connecting pipe 4 just when it is inflated, the elastic force of the lifting air cushion before it reaches the fatigue limit should be less than the elastic force of the buffer assembly, and the elastic force of the lifting air cushion after it reaches the fatigue limit should be greater than the elastic force of the buffer assembly.

[0031] See also Figure 3The buffer assembly includes a limit plate 18 fixedly connected to the inner wall of the connecting block 5, the movable rod 17 passes through the limit plate 18 and is slidably connected thereto, the outside of the movable rod 17 is fixedly connected to a fixed plate 20, a side of the fixed plate 20 close to the limit plate 18 is fixedly connected to a first elastic component 19, and the other end of the first elastic component 19 is fixedly connected to the limit plate 18;

[0032] The movable rod 17 is elastically supported by the first elastic component 19, the fixing plate 20 and the limiting plate 18. On the one hand, it can reset the movable rod 17. On the other hand, the movable rod 17 can move after the lifting air cushion reaches the fatigue limit, so as to achieve the blocking of the connecting pipe 4. The first elastic component 19 can be a spring. In addition, the limiting plate 18 can limit the movable rod 17, thereby improving the stability of the movable rod 17 when moving.

[0033] See also Figure 3 , Figure 4 and Figure 5 The self-locking mechanism includes a first rotating disk 14 fixed to the outside of the rotating rod 7, a card slot 6 is provided on the side wall of the first rotating disk 14, and a card rod 15 adapted to the card slot 6 is provided inside the connecting block 5, wherein a movable groove is provided on the inner wall of the connecting block 5, one end of the card rod 15 is connected to the side of the first rotating disk 14 in abutment, and the other end extends into the movable groove and is connected to the inner wall of the movable groove through the second elastic component 22;

[0034] Initially, the end of the clamping rod 15 is in contact with the side of the first turntable 14. When the valve core 3 completes the sealing of the connecting pipe 4, the clamping rod 15 is aligned with the clamping groove 6 on the side of the first turntable 14. Under the action of the second elastic component 22, the end of the clamping rod 15 automatically enters the inside of the clamping groove 6. The clamping rod 15 fixes the first turntable 14 through the clamping groove 6, and then fixes the rotating rod 7, thereby limiting the rotation of the valve core 3 and effectively ensuring the sealing effect of the valve core 3 on the connecting pipe 4. The second elastic component 22 can be a spring.

[0035] In another embodiment, see Figure 4 A channel is provided on the inner wall of the movable groove away from the clamping rod 15, and the channel passes through the connecting block 5. A traction rope 23 is fixedly connected to one end of the clamping rod 15 located inside the movable groove, and the traction rope 23 passes through the channel. An "L"-shaped rod 24 is fixedly connected to one end of the traction rope 23 passing through the channel. A fixed groove 25 matching the "L"-shaped rod 24 is provided on the side wall of the connecting block 5, wherein a pushing component is provided inside the fixed groove 25. When the driving mechanism drives the rotating rod 7 to rotate, the pushing component is used to push the "L"-shaped rod 24 to the outside of the fixed groove 25;

[0036] When the device is used up, the end of the "L"-shaped rod 24 is inserted into the fixing groove 25. At this time, the "L"-shaped rod 24 pulls the clamping rod 15 through the traction rope 23, thereby pulling the clamping rod 15 to the outside of the clamping groove 6. The clamping rod 15 loses its limit position, and the rotating rod 7 automatically resets under the action of the torsion spring 8, which is convenient for the next use. When used next time, the driving mechanism will also drive the rotating rod 7 to rotate, and the rotating rod 7 triggers the operation of the pushing component, which pushes the "L"-shaped rod 24 to the outside of the fixing groove 25. The traction of the "L"-shaped rod 24 is lost, and the clamping rod 15 automatically resets under the action of the second elastic component 22, so that when the device is used next time, the clamping rod 15 can enter the inside of the clamping groove 6 again, thereby fixing the first turntable 14 again.

[0037] See also Figure 5 The pushing assembly includes a push rod 26 slidably connected to the fixing groove 25, the push rod 26 extends into the connecting block 5, the push rod 26 is fixedly connected to the outside of the push rod 26 with a support plate 28, the support plate 28 is fixedly connected to a third elastic component 27 on a side away from the rotating rod 7, and the other end of the third elastic component 27 is fixedly connected to the inner wall of the connecting block 5, and an extrusion component is provided inside the connecting block 5. When the driving mechanism drives the rotating rod 7 to rotate, the extrusion component is used to squeeze the push rod 26;

[0038] Initially, the third elastic component 27 and the support plate 28 play an elastic supporting role for the push rod 26. The third elastic component 27 can be a spring. At this time, the push rod 26 cannot push the "L"-shaped rod 24 out of the fixed groove 25. When the rotating rod 7 rotates, the rotating rod 7 squeezes the push rod 26 through the squeezing component, so that the push rod 26 pushes the "L"-shaped rod 24 out of the fixed groove 25, thereby resetting the clamping rod 15, so that the clamping rod 15 can limit the first turntable 14 again.

[0039] See also Figure 5 The extrusion component includes a second rotating disk 30 fixed to the outside of the rotating rod 7, the end of the push rod 26 is in contact with the side wall of the second rotating disk 30, and a groove 29 is provided on the side wall of the second rotating disk 30;

[0040] Initially, the end of the push rod 26 is in contact with the groove 29 on the side of the second turntable 30. When the driving mechanism drives the rotating rod 7 to rotate, the rotating rod 7 drives the second turntable 30 to rotate, and the second turntable 30 squeezes the push rod 26, thereby pushing the "L"-shaped rod 24 to the outside of the fixed groove 25. There is no need to manually remove the "L"-shaped rod 24 from the inside of the fixed groove 25. After the "L"-shaped rod 24 is pushed out, the clamping rod 15 automatically resets, so that the clamping rod 15 can enter the clamping groove 6 again when the device is used next time, thereby fixing the first turntable 14 again.

[0041] Working principle: When the inflation control device is in use, the air inlet 1 is connected to the air outlet end on the inflation bottle, and the air outlet 2 is connected to the air inlet end on the lifting air cushion. The inflation bottle inflates the lifting air cushion through the connecting pipe 4. Initially, the valve core 3 inside the connecting pipe 4 is parallel to the connecting pipe 4, and the inflation bottle and the lifting air cushion are in a connected state. The gas inside the inflation bottle can enter the lifting air cushion through the connecting pipe 4. When the lifting air cushion is inflated, the gas will enter the air cavity 11, thereby pushing the first piston 12. The first piston 12 squeezes the gas inside the air cavity 11. The gas inside the air cavity 11 enters the hollow tube 21 through the air pipe 10. The air pressure inside the hollow tube 21 increases, pushing the second piston 16. The second piston 16 drives the movable rod 17 to move, so that the movable rod 17 can push The push plate 9 is moved to make the rotating rod 7 drive the valve core 3 to rotate until the valve core 3 is perpendicular to the connecting pipe 4. At this time, the connecting pipe 4 is in a closed state, and the gas inside the inflation bottle cannot enter the lifting air cushion through the connecting pipe 4, thereby achieving an inflation control purpose. It can effectively avoid the phenomenon that when the lifting air cushion is fully inflated, the inflation bottle continues to inflate the inside of the lifting air cushion, causing the lifting air cushion to exceed the fatigue limit, thereby ensuring the expansion degree of the lifting air cushion and improving the service life of the lifting air cushion. When the valve core 3 is perpendicular to the connecting pipe 4, the end of the clamping rod 15 automatically enters the clamping groove 6. The clamping rod 15 fixes the first turntable 14 through the clamping groove 6, and then fixes the rotating rod 7, thereby limiting the rotation of the valve core 3 and effectively ensuring the sealing effect of the valve core 3 on the connecting pipe 4.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
