Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 and Figure 2 shown, the present invention provides a pet treadmill with a resistance adjustment structure, including an annular outer shell 1 and three positioning rollers 2 distributed in a circumferential array. A running roller 3 is arranged between the three positioning rollers 2. The positioning rollers 2 abut against the surface of the running roller 3. First induction blocks 41 and second induction blocks 42 are arranged on both the left and right sides of the running roller 3, and pet toys are installed on the first induction blocks 41 and the second induction blocks 42.

[0020] The running roller 3 is made of a transparent material.

[0021] Among them, the toy diagrams on the first induction block 41 and the second induction block 42 are not shown in the figure. The pet toys on the first induction block 41 and the second induction block 42 can be set according to the preferences of each pet.

[0022] An induction mechanism for driving the first induction block 41 and the second induction block 42 to rotate intermittently when the running roller 3 rotates is arranged outside the running roller 3.

[0023] When the pet runs inside the running roller 3, it can drive the running roller 3 to rotate. By setting up an induction mechanism, the running roller 3 can drive the first induction block 41 and the second induction block 42 to rotate intermittently when it rotates. The pet toys on the first induction block 41 and the second induction block 42 will also rotate, thus generating a certain attraction to the pet and making the pet keep exercising.

[0024] An adjusting mechanism for driving the positioning roller 2, the first induction block 41 and the second induction block 42 to move linearly is arranged inside the annular housing 1.

[0025] By setting up the adjusting mechanism, the positioning roller 2, the first induction block 41 and the second induction block 42 can be driven to move away from the center position of the annular housing 1 or move closer to the center position of the annular housing 1, so that the whole device can be adapted to rollers of different sizes, that is, adapted to pets of different sizes, effectively improving the adaptability of the whole device.

[0026] Such as Figure 1 、 Figure 3 and Figure 4 As shown in the figures, the adjusting mechanism includes five threaded rods 51 rotatably connected inside the annular housing 1. The five threaded rods 51 are circumferentially distributed inside the annular housing 1. An internally threaded sleeve 52 threadedly connected to the threaded rod 51 is sleeved on the threaded rod 51. A bent rod 53 extending to the outside of the annular housing 1 is fixedly connected to the surface of the internally threaded sleeve 52. A linear groove 54 for the movement of the bent rod 53 and parallel to the threaded rod 51 is provided on the surface of the annular housing 1.

[0027] By setting up the linear groove 54, the movement path of the bent rod 53 can be restricted to prevent the bent rod 53 and the internally threaded sleeve 52 from rotating along with the threaded rod 51; One of the threaded rods 51 is driven by an external motor.

[0028] Such as Figure 1 and Figure 2 As shown in the figures, three of the bent rods 53 respectively correspond to the three positioning rollers 2 one by one. The positioning roller 2 is rotatably connected to the free end of the bent rod 53. The shapes of the three bent rods 53 are different from those of the other two bent rods 53. The free ends of the other two bent rods 53 are rotatably connected with a bearing plate 55.

[0029] Such as Figure 2 As shown in the figure, a vertical plate 56 is fixedly connected to the upper surface of the bearing plate 55. Electric telescopic rods 57 are fixedly connected to both opposite sides of the vertical plate 56. The first induction block 41 and the second induction block 42 are respectively installed at the free ends of the two electric telescopic rods 57. A fixed connection is made between the second induction block 42 and the electric telescopic rod 57.

[0030] Such as Figure 3 、 Figure 4 and Figure 5As shown, a ring-shaped frame 58 is rotatably connected inside the ring-shaped housing 1. A first gear 59 is fixed on the surface of the ring-shaped frame 58. A second gear 510 meshing with the first gear 59 is arranged at the end of each threaded rod 51.

[0031] With the above solution, when one of the threaded rods 51 is driven to rotate by an external motor, the first gear 59 can be driven to rotate by the second gear 510 coaxially fixed thereto. Then, the first gear 59 can drive the remaining second gears 510 to rotate therewith, so that all the threaded rods 51 can rotate simultaneously.

[0032] As Figure 2 shown, the corresponding first guiding block 41 and second guiding block 42 form a cylindrical shape. The guiding mechanism includes spiral sliding grooves 61 formed on the surfaces of the first guiding block 41 and the second guiding block 42 and distributed at equal circumferential intervals. The number of the spiral sliding grooves 61 is at least two. A sliding column 62 is inserted on the surface of the running roller 3. The sliding column 62 is adapted to the spiral sliding grooves 61.

[0033] When the sliding column 62 rotates following the running roller 3, the sliding column 62 can gradually enter the spiral sliding grooves 61 and push the first guiding block 41, the second guiding block 42 and the bearing plate 55 to rotate. Then, the pet toys mounted on the first guiding block 41 and the second guiding block 42 will also rotate therewith, generating an attraction to the pets in motion.

[0034] Wherein, a circular hole for inserting the sliding column 62 is formed on the surface of the running roller 3, and the sliding column 62 can be directly pulled out from the running roller 3.

[0035] As Figure 2 and Figure 6 shown, a groove 63 is formed at the edge of the bearing plate 55. The number of the grooves 63 is the same as that of the spiral sliding grooves 61 and they are in one-to-one correspondence. A positioning frame 64 adapted to the groove 63 is sleeved on the surface of the running roller 3. Both ends of the positioning frame 64 are triangular. The distance between one end of the positioning frame 64 and the sliding column 62 is equal to the distance between the other end of the positioning frame 64 and the sliding column 62.

[0036] Wherein, the positioning frame 64 is hoop-shaped on the running roller 3 and can be directly detached from the running roller 3.

[0037] When the sliding column 62 enters the spiral sliding grooves 61 to push the first guiding block 41 and the second guiding block 42 to rotate, and then when the sliding column 62 disengages from the spiral sliding grooves 61, one end of the positioning frame 64 enters the groove 63, restricting the rotation angle of the first guiding block 41, the second guiding block 42 and the bearing plate 55.

[0038] As Figure 7 and Figure 8As shown, a cleaning cloth 7 is sleeved on the surfaces of the first guiding block 41 and the second guiding block 42.

[0039] The corresponding first guiding block 41 and second guiding block 42 are driven by the electric telescopic rod 57 to move in opposite directions. Then, the cleaning cloth 7 is sleeved on the first guiding block 41 and the second guiding block 42. The cleaning cloth 7 can be used once and then discarded, or it can be washed and reused multiple times. Then, the running roller 3 is placed between the two groups of the first guiding block 41 and the second guiding block 42. The first guiding block 41 and the second guiding block 42 are driven by the electric telescopic rod 57 to move towards the side close to each other, so that the first guiding block 41 and the second guiding block 42 clamp the running roller 3. At this time, the running roller 3 is manually pushed to rotate, so that the dirt on the surface of the running roller 3 is wiped clean by the cleaning cloth 7; The cleaning cloth 7 can be used dry or wet.

[0040] Resistance mechanisms are provided on both bearing plates 55. The surface of the first guiding block 41 away from the spiral chute 61 has resistance patterns.

[0041] Among them, the resistance patterns are not shown in the figure.

[0042] By setting the resistance mechanism, the first guiding block 41 can be driven to rotate 180 degrees, and the side with the resistance patterns is oriented towards the running roller 3; When the side of the first guiding block 41 with the resistance patterns abuts against the running roller 3, a certain resistance can be brought to the rotation of the running roller 3, so as to improve the exercise effect of the pet. As Figure 12 shown.

[0043] When the first guiding block 41 is in closer contact with the running roller 3, the greater the resistance provided; When the pet has a greater intention to exercise, the first guiding block 41 can be used to provide resistance, and there is no need to induce the rotation of the pet toy.

[0044] When the first guiding block 41 provides resistance, the positioning frame 64 and the sliding column 62 need to be removed from the running roller 3.

[0045] As Figure 9 、 Figure 10 and Figure 11 shown, the resistance mechanism includes a circular plate 81 fixedly connected to the upper end of the electric telescopic rod 57. A hollow shaft 82 rotatably connected to the circular plate 81 is sleeved on the circular plate 81. A third gear 83 fixedly connected to the hollow shaft 82 is sleeved on the hollow shaft 82. A rack 84 is vertically fixed on the upper surface of the bearing plate 55.

[0046] Among them, the third gear 83 can mesh with the rack 84.

[0047] As Figure 11As shown, a central shaft 85 is rotatably connected to the upper surface of the circular plate 81. A first induction block 41 is fixedly connected to the upper end of the central shaft 85. A ratchet wheel 86 fixedly connected to the central shaft 85 is sleeved on the central shaft 85. A plurality of extension rods 87 evenly distributed at equal intervals in a circumferential manner are fixedly connected to the inner wall of the hollow shaft 82. A ratchet tooth 88 is rotatably connected to each extension rod 87. The ratchet tooth 88 meshes with the ratchet wheel 86. A spring 89 is fixedly connected to the inner wall of the hollow shaft 82, and the other end of the spring 89 is fixed to the surface of the ratchet tooth 88.

[0048] Among them, both the first induction block 41 and the second induction block 42 are magnetic blocks, and the external pet toy also has mutually attracting magnetic blocks, which can directly attract the pet toy to the first induction block 41 and the second induction block 42.

[0049] The working principle of the present invention: When it is necessary to replace the running rollers 3 of different sizes, one of the threaded rods 51 is rotated by an external motor. The threaded rod 51 can drive the first gear 59 to rotate through the second gear 510 coaxially fixed thereto. Then the first gear 59 can drive the remaining second gears 510 to rotate accordingly, so that all the threaded rods 51 can rotate simultaneously; The threaded rod 51 can drive the inner threaded sleeve 52 and the bent rod 53 to move along the linear groove 54. Among them, the three linear grooves 54 can drive the positioning rollers 2 to move accordingly, and the other two bent rods 53 can drive the bearing plate 55, the first induction block 41 and the second induction block 42 to move accordingly, so that the positioning rollers 2, the first induction block 41 and the second induction block 42 can move both away from the center of the annular housing 1 and towards the center of the annular housing 1; After the positioning rollers 2, the first induction block 41 and the second induction block 42 move away from the center of the annular housing 1, the running roller 3 is loosened, and other models of running rollers 3 can be replaced and placed between the three positioning rollers 2. Then, the positioning rollers 2, the first induction block 41 and the second induction block 42 are driven to move towards the center of the annular housing 1, so that the three positioning rollers 2 abut against the surface of the running roller 3, and the replacement of the running roller 3 is completed; When the pet runs in the running roller 3, the running roller 3 will rotate. The running roller 3 can drive the sliding column 62 to rotate accordingly. The sliding column 62 can gradually enter the spiral chute 61 and push the first induction block 41, the second induction block 42 and the bearing plate 55 to rotate. Then the pet toy installed on the first induction block 41 and the second induction block 42 will also rotate accordingly, generating an attraction to the moving pet; When the sliding column 62 enters the spiral chute 61, it pushes the first guiding block 41 and the second guiding block 42 to rotate. Then, while the sliding column 62 disengages from the spiral chute 61, one end of the positioning frame 64 enters the groove 63 to limit the rotation angles of the first guiding block 41, the second guiding block 42, and the bearing plate 55. When it is necessary to clean the running roller 3, the corresponding first guiding block 41 and second guiding block 42 are driven by the electric telescopic rod 57 to move in opposite directions. Then, a cleaning cloth 7 is put on the first guiding block 41 and the second guiding block 42. The cleaning cloth 7 can be used once or can be reused after washing. Then, the running roller 3 is placed between the two groups of the first guiding block 41 and the second guiding block 42. The first guiding block 41 and the second guiding block 42 are driven by the electric telescopic rod 57 to move towards each other to clamp the running roller 3. At this time, the running roller 3 is manually pushed to rotate, so that the dirt on the surface of the running roller 3 is wiped clean by the cleaning cloth 7. When the pet has a high intention to exercise and does not need a toy to attract it, the electric telescopic rod 57 drives the circular plate 81, the central shaft 85, the first guiding block 41, and the third gear 83 to move towards the side close to the vertical plate 56 (the electric telescopic rod 57 drives the corresponding second guiding block 42 to move out of the way at the same time). The third gear 83 can gradually mesh with the rack 84 and rotate. The third gear 83 can drive the ratchet tooth 88 to rotate through the hollow shaft 82 and the extension rod 87. The ratchet tooth 88 can drive the ratchet wheel 86, the central shaft 85, and the first guiding block 41 to rotate, so that the side of the first guiding block 41 with the resistance pattern faces the running roller 3.

[0050] When the side of the first guiding block 41 with the resistance pattern abuts against the running roller 3, it can bring a certain resistance to the rotation of the running roller 3, improving the exercise effect of the pet, as Figure 12 shown.

[0051] When the first guiding block 41 is in closer contact with the running roller 3, the greater the resistance provided.
