[0003] However, most common treadmills are for indoor use, require power supply, and have intelligent functions. It is difficult to place them outdoors and cannot meet the outdoor fitness needs of people. The main reasons are that the indoor temperature is low, which is convenient for improving the running experience of exercisers. The outdoor temperature is relatively high, and the heat generated by running in place cannot be quickly discharged, resulting in a poor exercise experience. Moreover, due to the influence of wind, rain, dust, etc., the service life of the treadmill is easily reduced, and the maintenance cost is also increased.
[0004] Therefore, the utility model provides an outdoor caterpillar-track mechanical treadmill. Content of the Utility Model

[0020] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: an outdoor crawler mechanical treadmill, including a base 1. Legs 2 are provided at the bottom of the base 1. The legs 2 play a role in supporting the base 1. Shock-absorbing rubber pads can be installed at the bottom of the legs 2. Drive shafts 3 are rotatably connected to the front and rear ends of the base 1. Specifically, cantilevers 11 rotatably connected to both ends of the drive shafts 3 are welded to both ends of the base 1. Crawler wheels 8 are fixedly sleeved on the drive shafts 3 near both ends. A connecting crawler 4 is connected between the crawler wheels 8 at both ends of the base 1. Exercise personnel can perform running training on the connecting crawler 4. Among them, support plates 12 can be fixedly connected to the bottom of the base 1 near both sides. A roller 13 with both ends rotatably connected to the support plates 12 is provided below the base 1. The roller 13 abuts against the inner bottom of the connecting crawler 4. The roller 13 plays a role in tensioning the connecting crawler 4, improving the flatness of the upper surface of the connecting crawler 4, and further improving the smoothness of running exercise for exercise personnel. It should be noted that a rubber sleeve can be sleeved on the roller 13, and the purpose is to apply a resistance to the free rotation of the connecting crawler 4.
[0022] Furthermore, a vertical shaft 5 located inside the connecting crawler 4 is rotatably connected to the top of the base 1. Specifically, a positioning sleeve can be welded to the top of the base 1. The bottom of the vertical shaft 5 is sleeved in the positioning sleeve, and then a bearing is provided between the positioning sleeve and the vertical shaft 5. A transmission combination 6 is provided between the vertical shaft 5 and the drive shaft 3. Under the transmission of the transmission combination 6, when the drive shaft 3 rotates, the vertical shaft 5 rotates. That is to say, when exercise personnel run on the connecting crawler 4, the drive shaft 3 will rotate and then drive the vertical shaft 5 to rotate, having a function of linkage control. Blades 7 are fixedly connected to the outer peripheral wall of the vertical shaft 5. When the blades 7 revolve, an upward airflow will be generated to ventilate and cool the exercise personnel on the connecting crawler 4. It should be noted that the settings of the transmission combination 6, the vertical shaft 5 and the blades 7 can provide a resistance to the operation of the connecting crawler 4, and this resistance can ensure the safety of exercise personnel during exercise on the connecting crawler 4.
[0023] Specifically, the transmission assembly 6 includes an intermediate shaft 61, a bevel gear set 62, a first bevel gear 63, and a second bevel gear 64. The intermediate shaft 61 is rotatably connected to the top of the base 1. The transmission shaft 3 is connected to one end of the intermediate shaft 61 through the bevel gear set 62. The bevel gear set 62 includes two meshing transmission bevel gears, and the two transmission bevel gears are fixedly connected to the intermediate shaft 61 and the transmission shaft 3 respectively. A first bevel gear 63 is fixedly connected to the other end of the intermediate shaft 61. The second bevel gear 64 is fixedly sleeved on the vertical rotating shaft 5 and meshes with the first bevel gear 63. Thus, when the transmission shaft 3 rotates, it can drive the vertical rotating shaft 5 to rotate through the intermediate shaft 61. There may be two intermediate shafts 61, that is, the transmission shaft 3 at both the front and rear ends of the base 1 can transmit power to the vertical rotating shaft 5 through the intermediate shaft 61.
[0024] In this embodiment, the second bevel gear 64 is a ratchet gear structure. That is, when the second bevel gear 64 stops rotating, the vertical rotating shaft 5 can continue to rotate by inertia, and when the rotation speed of the second bevel gear 64 increases, it can drive the vertical rotating shaft 5 to rotate again.
[0025] In this embodiment, the connecting crawler 4 includes a pedal 41 and transmission chains 42 connected to both ends of the pedal 41. Sprockets 81 meshing with the transmission chains 42 are provided on the crawler wheels 8. One side of the pedal 41 and the outer periphery of the transmission chain 42 are fixedly connected through ear seats. The pedal 41 is a rectangular bar structure and is evenly distributed.
[0026] In this embodiment, a protective ring 52 sleeved on the outer periphery of the fan blade 7 is welded to the outer peripheral wall of the vertical rotating shaft 5 through a support rod 51. The protective ring 52 serves to protect the fan blade 7 and prevent it from being damaged after accidental collision.
[0027] In this embodiment, handrail frames 14 are welded to both sides of the base 1 near the front end. The handrail frames 14 are bent into a U-shaped by bent pipes, which is convenient for the exercisers to hold.
[0028] Working principle: When exercising is needed, the exerciser holds the handrail frames 14 with hands and then steps on the connecting crawler 4. First, walk forcefully, and the connecting crawler 4 starts to rotate at a low speed. The transmission chain 42 drives the sprocket 81 to rotate. The transmission shaft 3 rotates and drives the intermediate shaft 61 to rotate through the bevel gear set 62. The first bevel gear 63 drives the second bevel gear 64 to rotate, and finally drives the vertical rotating shaft 5 to rotate. At this time, the fan blade 7 forms an upward airflow to ventilate and dissipate heat for the exerciser, improving the comfort of running exercise. When the exerciser stops exercising, the connecting crawler 4 can stop in place, and the fan blade 7 will continue to rotate for a period of time and then stop.
[0029] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
