DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1 As shown, a preferred embodiment of a cardiopulmonary resuscitation training device of the present invention includes a prosthesis 1, a pressing plate 2, a telescopic rod 3, a driving device, a transmission device 5, a depth limiting mechanism and a depth indicator 7. The prosthesis 1 has a mounting cavity 11, and the pressing plate 2, telescopic rod 3, transmission device 5 and depth limiting mechanism are all located in the mounting cavity 11. The telescopic rod 3 is rotatably arranged in the mounting cavity 11 of the prosthesis 1, and the pressing plate 2 is installed at the upper end of the telescopic rod 3. After being compressed, the telescopic rod 3 can automatically reset, thereby resetting the position of the pressing plate 2 to facilitate the next pressing. The driving device is arranged in the mounting cavity 11, and the input end of the driving device is located outside the prosthesis 1. The driving device is connected to the transmission device 5, and the driving device is used to drive the transmission device 5. The depth limiting mechanism is connected to the transmission device 5, and the transmission device 5 drives the depth limiting mechanism to rise and fall to change the position of the limited depth. The depth indicating member 7 is installed on the depth limiting mechanism, and the upper end of the depth indicating member 7 is exposed outside the prosthesis 1. The depth indicating member 7 is provided with a scale, which is used to indicate the pressing depth, that is, the maximum pressing depth. Pressing to the maximum depth indicates that the training requirements are not met.

[0023] like Figure 2As shown, the telescopic rod 3 includes a first rod 31, a spring 32, a second rod 33, and a sealing plug 34. The first rod 31 is rotatably mounted in the mounting cavity 11 of the prosthesis 1 via a bearing, and the pressing plate 2 is mounted on the upper end of the first rod 31. The second rod 33 has a receiving cavity 331, the upper and lower ends of which are both connected to the outside world. The lower end of the receiving cavity 331 is provided with an internal thread, and the sealing plug 34 is screwed into the receiving cavity 331. This allows the sealing plug 34 to be removed from the second rod 33 when needed. The sealing plug 34 can be installed by simply rotating it, making assembly and disassembly convenient. The lower end of the first rod 31 is inserted into the receiving cavity 331. The spring 32 is disposed within the accommodating cavity 331. The upper end of the spring 32 abuts against the lower end of the first rod 31, and the lower end of the spring 32 abuts against the sealing plug 34. As the first rod 31 moves downward, the spring 32 is compressed. Once the external force applied to the first rod 31 is removed, the spring 32 drives the first rod 31 back to its original position, thereby driving the pressing plate 2 back to its original position, and thus the prosthesis 1 back to its original position. A first anti-slip portion 311 is provided on the first rod 31, and a second anti-slip portion 332 is provided at the bottom of the second rod 33. The first anti-slip portion 311 cooperates with the second anti-slip portion 332 to prevent the first rod 31 from escaping from the second rod 33.

[0024] The drive device comprises a rotating shaft 41, a handle (not shown), a worm gear 43, a worm 44, and two mounting plates 45. The two mounting plates 45 are mounted within the mounting cavity 11 of the prosthesis 1, with the rotating shaft 41 rotatably mounted on the two mounting plates 45. One end of the rotating shaft 41 extends outside the prosthesis 1 and connects to the handle, allowing the handle to be rotated outside the prosthesis 1 to drive the rotating shaft 41. The worm 44 is fixed to the rotating shaft 41, and the worm gear 43 is mounted on the second rod 33 of the telescopic rod 3, meshing with the worm gear 43. Turning the handle rotates the rotating shaft 41, which in turn rotates the worm 44, which in turn rotates the worm gear 43, which in turn rotates the second rod 33 of the telescopic rod 3. The coordination of the worm gear 43 and worm 44 also prevents self-locking of the second rod 33, meaning that the second rod 33 can only rotate when driven by the worm gear 44.

[0025] The transmission device 5 is a lifting sleeve, which is screwed onto the second rod 33. The depth limiting mechanism is mounted on the lifting sleeve. The second rod 33 rotates to drive the lifting sleeve to move up and down, thereby driving the depth limiting mechanism to move up and down.

[0026] The depth limiting mechanism comprises a limiting post 61 and a connecting plate 62. The connecting plate 62 is mounted on the lifting sleeve. Four limiting posts 61 are provided on the connecting plate 62. The four limiting posts 61 are evenly distributed on the connecting plate 62. The limiting posts 61 are used to limit the downward movement of the pressing plate 2, thereby limiting the pressing depth and preventing excessive pressing. In other embodiments, two limiting posts 61 or more can be used, as required. A guide post 63 is provided in the prosthesis 1. There are two guide posts 63, which are evenly distributed around the second rod 33. The guide posts 63 are inserted into the connecting plate 62 and are used to guide the connecting plate 62 to maintain its upward and downward movement.

[0027] In other embodiments, Figure 3 As shown, a touch switch (not shown) is provided on the limit column 61, and the touch switch is connected to a power supply (not shown) and an alarm (not shown). Pressing down and touching the touch switch will also energize the alarm and sound an alarm. The alarm can be a buzzer, an alarm light, or a combination of the two.

[0028] During training, the prosthesis 1 is pressed, and the prosthesis 1 drives the pressing plate 2 to move downward, and the pressing plate 2 drives the first rod 31 to move downward, and the first rod 31 compresses the spring 32. If the pressing depth exceeds the depth required by training, the pressing plate 2 will contact the limit column 61, and the pressing plate 2 cannot continue to move downward, which can remind the trainee that the pressing depth is excessive and the pressing depth needs to be adjusted.

[0029] When it is necessary to simulate training for different age groups, remove the sealing plug 34 and replace the spring 32 with a spring 32 of appropriate elastic force to simulate the needs of different pressing strengths. Then, reinstall the sealing plug 34 on the second rod 33, making it easy to replace the spring 32. At the same time, turn the handle to rotate the worm 44. The rotation of the worm 44 drives the worm wheel 43 to rotate. The worm wheel 43 rotates the second rod 33. The rotation of the second rod 33 drives the lifting sleeve to rise and fall. The lifting sleeve drives the limit column 61 to rise and fall, thereby changing the pressing depth limit. When the limit column 61 rises and falls, the depth indicator 7 also rises and falls. When the limited pressing depth is adjusted to the predetermined value, stop turning the handle, and the height of multiple limit columns 61 can be adjusted synchronously, that is, the height of all limit columns 61 can be completed at one time, which is convenient to adjust. The corresponding training requirements can be adjusted by replacing the spring 32 and the limited depth to meet the training of different age groups.

[0030] Example 2

[0031] The difference between this embodiment and the embodiment lies in the different structures of the transmission device 5 and the depth limiting mechanism.

[0032] like Figure 2As shown, the transmission device 5 includes a first transmission gear 51 and a second transmission gear 52. The first transmission gear 51 is installed on the telescopic rod 3. A second transmission gear 52 is installed on each depth limiting mechanism, and the second transmission gear is engaged with the first gear.

[0033] The depth limiting mechanism includes a connecting plate 62, a limiting column 61, a limiting screw 64, and a limiting seat 65. There are four limiting seats 65, each of which is rotatably provided with a limiting screw 64. Each limiting screw 64 is provided with a second transmission gear 52. The limiting screw 64 has an internal thread, and the limiting column 61 is internally threaded on the internal thread. The connecting plate 62 is fixed to the top of the limiting column 61. The limiting screw 64 rotates on the limiting seat 65 to drive the limiting column 61 to rise and fall.

[0034] When the limit depth needs to be adjusted, the handle is turned to rotate the worm 44. The rotation of the worm 44 drives the worm wheel 43, which in turn rotates the second rod 33. The rotation of the second rod 33 drives the first transmission gear 51. The rotation of the first transmission gear 51 drives all the second transmission gears. The second transmission gears drive the corresponding limit screw 64 to rotate on the limit seat 65. The limit screw 64 drives the limit column 61 to rise and fall, thereby changing the pressing depth limit. When the limit column 61 rises and falls, the depth indicator 7 also rises and falls. When the limited pressing depth is adjusted to the predetermined value, the handle is stopped.

[0035] Of course, in other embodiments, a touch switch may be provided on the connection disk 62 , and the touch switch is connected to a power source and an alarm, so that pressing down and contacting the touch switch will also energize the alarm and sound an alarm.

[0036] The above is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
