[0030] The fixed protection mechanism 3 is installed on the support column 21, and the fixed protection mechanism 3 includes a bidirectional threaded rod 31, the bidirectional threaded rod 31 is rotatably installed in the middle of the support column 21, and a protection piece 32 is symmetrically installed on the bidirectional threaded rod 31, and a U-shaped frame 33 is symmetrically installed on the support column 21, and the U-shaped frame 33 is slidably matched with the protection piece 32 on the same side, and a through slot 201 is opened in the middle of the support column 21, and a driving rod 34 is rotatably installed in the through slot 201, and a handle 35 is fixedly installed on one end of the driving rod 34 through the through slot 201, and a worm 36 is fixedly sleeved on the driving rod 34, and a worm wheel 37 is fixedly sleeved in the middle of the bidirectional threaded rod 31, and the worm wheel 37 is meshed with the worm 36;

[0031] The movable block 4 is slidably mounted on the front end of the base 1, and the front end of the movable block 4 is symmetrically mounted with a front stabilizing support leg 41, and the base 1 is mounted with an adjusting member 5 for driving the movable block 4 to slide;

[0032] The vertical pole 6 is fixedly mounted on the front end of the movable block 4 , and a detector 7 is mounted on the top of the vertical pole 6 . A handrail 61 is mounted on the vertical pole 6 below the detector 7 , and a wire clamp assembly 8 is mounted on the handrail 61 .

[0033] Among them, the protective member 32 includes a vertical plate 321, one end of the vertical plate 321 is threadedly connected to the bidirectional threaded rod 31, and the two sides of the vertical plate 321 are slidably matched with the inner wall of the U-shaped frame 33, and a horizontal plate 322 is fixedly installed on the top outer wall of the vertical plate 321, and a sliding groove 301 is opened on the horizontal plate 322, and a support rod 323 is fixedly installed in the sliding groove 301, and a vertical rod 324 is slidably installed on the support rod 323, and a protective ring 325 is fixedly installed on the bottom end of the vertical rod 324, and a return spring 326 is sleeved on the support rod 323, and the vertical rod 324 is slidably matched with the sliding groove 301, one end of the return spring 326 is fixedly connected to the horizontal plate 322, and the other end of the return spring 326 is fixedly connected to the outer wall of the vertical rod 324.

[0034] It should be noted that when in use, after the person being tested sits on the seat cushion 22, the handle 35 is turned to drive the driving rod 34 to rotate, so that the driving rod 34 engages with the worm gear 37 through the worm 36, thereby driving the bidirectional threaded rod 31 to rotate. When the bidirectional threaded rod 31 rotates, the vertical plates 321 on both sides are driven to move closer to the seat cushion 22 along the U-shaped frame 33, thereby driving the vertical rod 324 on the horizontal plate 322 to drive the protective ring 325 to move closer to the person sitting on it, wrapping the waist and abdomen of the person sitting on it, and the vertical rod 324 used to fix the protective ring 325 is slidably installed on the support rod 323, and is pulled by the return spring 326. The protective ring 325 is moved so as to be attached to the waist and abdomen of the rider, so that it can synchronously follow the rider's movements and loosen synchronously, thereby reducing the restraint on the rider. Then, the adjustment member 5 is used to adjust the distance between the upright pole 6 and the base 1, so that people of different physiques can hold the armrest 61 in a comfortable posture to perform exercise experiments. During exercise, the detection wearable device is connected through the detector 7, and then the detection wearable device is worn on the rider to perform exercise experiment detection. The cables used for connection can be fixed and managed by the wire clamp assembly 8, so as to avoid the cables being placed in a messy manner and improve the overall safety of the exercise experiment.

[0035] In the present embodiment, the length of the U-shaped frame 33 is slightly smaller than the length of the two-way threaded rod 31 exposed at one end of the support column 21. In this way, when the vertical plate 321 slides to the end along the U-shaped frame 33 and continues to rotate the two-way threaded rod 31, the vertical plate 321 follows the two-way threaded rod 31 and rotates forward or backward synchronously, thereby rotating the protective ring 325 away from the support column 21, making it convenient for the rider to pedal the bicycle 2 up and down. After riding the bicycle 2, when it needs to be fixed, first rotate the vertical plates 321 on both sides to align with the U-shaped frame 33 and fix them by hand, and then control the two-way threaded rod 31 to reverse, so that the vertical plate 321 can slide back into the U-shaped frame 33 and slide along the two-way threaded rod 31, thereby driving the protective ring 325 to wrap and protect the rider's waist and abdomen.

[0036] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The adjusting member 5 includes a screw rod 51, which is rotatably mounted on the base 1, and a hand wheel 53 is fixedly mounted on one end of the screw rod 51, a transmission block 52 is threadedly mounted on the screw rod 51, and the transmission block 52 is fixedly connected to the movable block 4 by screws, and the movable block 4 is provided with a through hole through which the screw rod 51 passes;

[0037] It should be noted that when the adjusting member 5 is used, the hand wheel 53 is rotated to drive the screw rod 51 to rotate, so that the screw rod 51 drives the movable block 4 to slide along the base 1 through the transmission block 52, thereby adjusting the distance between the vertical rod 6 and the base 1.

Here, the detectors 7 are all data acquisition and detection instruments commonly used in cardiopulmonary exercise experiments in the prior art. The specific working principles will not be described here in detail, and can be flexibly adapted according to needs.

[0039] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 5 The wire clamp assembly 8 includes a connecting block 81 and a wire clamp block 82, which are detachably mounted on the handrail 61 by screws, and a plurality of wire clamp grooves 801 are provided on the end surface of the wire clamp block 82, a U-shaped rod 83 is installed on the outside of the plurality of wire clamp grooves 801 on the wire clamp block 82, a plurality of connecting springs 84 are installed on the U-shaped rod 83, and a wire pressing column 85 is fixedly mounted on one end of the plurality of connecting springs 84 away from the U-shaped rod 83, and the wire pressing column 85 is pressed and inserted in the corresponding wire clamp groove 801.

[0040] It should be noted that: before wearing the wearable device to be detected on the rider, first pull the wire pressing post 85 to disengage it from the wire clamp groove 801, then pass the connected cable through the wire clamp groove 801, and then clamp the cable passing through the wire clamp groove 801 with the wire pressing post 85. When the length needs to be adjusted, pull the connecting spring 84 upward to pull the clamped cable to drag it. After adjustment, use the spring force of the connecting spring 84 to clamp the cable in the wire pressing post 85 and the wire clamp groove 801, so as to facilitate the wiring harness management of the connected cables, thereby avoiding wiring confusion and causing the wiring harness to trip relevant personnel, thereby improving the overall safety.

[0041] The working principle of the convenient fixed cardiopulmonary exercise test device provided by the utility model is as follows:

[0042] When in use, after the person being tested sits on the seat cushion 22, the handle 35 is turned to drive the driving rod 34 to rotate, so that the driving rod 34 engages with the worm gear 37 through the worm 36, thereby driving the bidirectional threaded rod 31 to rotate. When the bidirectional threaded rod 31 rotates, the vertical plates 321 on both sides are driven to move toward the seat cushion 22 along the U-shaped frame 33, thereby driving the vertical rod 324 on the horizontal plate 322 to drive the protective ring 325 to move toward the person sitting on the seat cushion 22, wrapping the waist and abdomen of the person sitting on the seat cushion. The vertical rod 324 used to fix the protective ring 325 is slidably installed on the support rod 323, and is pulled by the reset spring 326 to make the protective ring 325 move. The protective ring 325 is movably attached to the waist and abdomen of the rider, so that it can synchronously follow the rider's movements and loosen synchronously, thereby reducing the restraint on the rider. Then, the adjustment member 5 is used to adjust the distance between the upright pole 6 and the base 1, so that people of different physiques can hold the armrest 61 in a comfortable posture to perform sports experiments. During exercise, the detection wearable device is connected through the detector 7, and then the detection wearable device is worn on the rider to perform sports experiments. The cables used for connection can be fixed and managed by the wire clamp assembly 8, thereby avoiding the messy placement of cables and improving the overall safety of the sports experiment.

[0043] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
