Description

Technical Field

[0001] This invention belongs to the field of animal training technology, specifically a pet treadmill with a resistance adjustment structure. Background Technology

[0002] A pet treadmill is an exercise device specifically designed for small animals. It typically uses a roller structure to help them exercise independently within a limited space. Designed to address the issue of overweight pets, pet treadmills have become a popular home health management device. They are generally suitable for pet owners living in small environments or without sufficient activity space, allowing them to compensate for insufficient exercise.

[0003] However, some pets may be reluctant to exercise on treadmills, and existing pet treadmills often lack incentives to encourage pets to move, requiring pet owners to provide guidance. Summary of the Invention

[0004] To address the issue mentioned in the background art that requires pet owners to provide guidance, this invention provides a pet treadmill with a resistance adjustment structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pet treadmill with a resistance adjustment structure, comprising an annular outer shell and three positioning rollers arranged in a circumferential array, a running roller disposed between the three positioning rollers, the positioning rollers abutting against the surface of the running roller, a first guide block and a second guide block disposed on both the left and right sides of the running roller, pet toys mounted on the first guide block and the second guide block, an induction mechanism disposed on the outer side of the running roller to drive the first guide block and the second guide block to rotate intermittently when the running roller rotates, and an adjustment mechanism disposed inside the annular outer shell for driving the positioning rollers, the first guide block and the second guide block to perform linear motion.

[0006] Preferably, the adjusting mechanism includes five threaded rods rotatably connected within the annular housing. The five threaded rods are distributed circumferentially within the annular housing, and each threaded rod is fitted with an internal threaded sleeve that is threadedly connected to it.

[0007] Preferably, the inner threaded sleeve surface is fixedly connected to a bent rod extending to the outside of the annular outer shell, and the annular outer shell surface is provided with straight grooves that allow the bent rod to move and are distributed parallel to the threaded rod.

[0008] Preferably, the three bending rods correspond one-to-one with the three positioning rollers, and the positioning rollers are rotatably connected to the free ends of the bending rods. The three bending rods have different shapes from the other two bending rods, and the free ends of the other two bending rods are rotatably connected to the bearing plates.

[0009] Preferably, a vertical plate is fixedly connected to the upper surface of the bearing plate, and electric telescopic rods are fixedly connected to both opposite sides of the vertical plate. The first guide block and the second guide block are respectively installed at the free ends of the two electric telescopic rods, and the second guide block is fixedly connected to the electric telescopic rod.

[0010] Preferably, an annular frame is rotatably connected inside the annular shell, a first gear is fixed on the surface of the annular frame, and a second gear that meshes with the first gear is provided at the end of each threaded rod.

[0011] Preferably, the corresponding first and second guiding blocks form a cylindrical shape, and the guiding mechanism includes spiral grooves formed on the surfaces of the first and second guiding blocks and distributed circumferentially at equal intervals. The number of spiral grooves is at least two, and a sliding column is inserted into the surface of the running roller, the sliding column being adapted to the spiral groove.

[0012] Preferably, the edge of the bearing plate is provided with grooves, the number of which is the same as the number of spiral grooves and corresponds one-to-one. The surface of the running roller is fitted with a positioning frame that matches the grooves. Both ends of the positioning frame are triangular. The distance between one end of the positioning frame and the sliding column is equal to the distance between the other end of the positioning frame and the sliding column.

[0013] Preferably, the surfaces of the first and second guide blocks are covered with cleaning cloths, and both of the bearing plates are provided with resistance mechanisms. The surface of the first guide block away from the spiral groove has resistance patterns. The resistance mechanism includes a circular plate fixedly connected to the upper end of the electric telescopic rod. A hollow shaft rotatably connected to the circular plate is fitted on the circular plate, and a third gear fixedly connected to the hollow shaft is fitted on the hollow shaft. A rack is vertically fixed to the upper surface of the bearing plate.

[0014] Preferably, a central shaft is rotatably connected to the upper surface of the circular plate, the first guiding block is fixedly connected to the upper end of the central shaft, a ratchet is fitted on the central shaft and fixedly connected thereto, a plurality of extension rods are fixedly connected to the inner wall of the hollow shaft in a circumferentially equidistant arrangement, each extension rod is rotatably connected to a ratchet tooth, the ratchet tooth meshes with the ratchet wheel, a spring is fixedly connected to the inner wall of the hollow shaft, and the other end of the spring is fixed to the surface of the ratchet tooth.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] When a pet runs inside the running roller, it can drive the running roller to rotate. By setting up an induction mechanism, the running roller can drive the first and second induction blocks to rotate intermittently when it rotates. The pet toys on the first and second induction blocks will also rotate, thereby attracting the pet and making the pet continue to exercise.

[0017] By setting an adjustment mechanism, the positioning roller, the first guide block and the second guide block can be driven to move away from the center of the annular shell or move closer to the center of the annular shell, so that the whole device can be adapted to rollers of different sizes, that is, to pets of different sizes, effectively improving the overall adaptability of the device.

[0018] Drive the corresponding first and second guide blocks to move in opposite directions using an electric telescopic rod. Then, put a cleaning cloth on the first and second guide blocks. The cleaning cloth can be used for one-time use or washed and reused multiple times. Then, place the running roller between the two sets of first and second guide blocks. Drive the first and second guide blocks to move closer to each other using an electric telescopic rod, so that the first and second guide blocks clamp the running roller. At this time, manually push the running roller to rotate, so that the dirt on the surface of the running roller is wiped clean by the cleaning cloth.

[0019] By setting a resistance mechanism, the first guide block can be driven to rotate 180 degrees, so that the side with the resistance pattern faces the running roller.

[0020] When the side of the first guide block with resistance texture touches the running roller, it can bring a certain resistance to the rotation of the running roller, thus improving the pet's exercise effect.

[0021] The closer the first guide block is to the running roller, the greater the resistance it provides;

[0022] When a pet has a strong desire to move, the first guide block can provide resistance, eliminating the need for the pet toy to rotate to induce movement. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 and Figure 2 As shown, the present invention provides a pet treadmill with a resistance adjustment structure, including an annular shell 1 and three positioning rollers 2 arranged in a circumferential array. A running roller 3 is arranged between the three positioning rollers 2, and the positioning rollers 2 abut against the surface of the running roller 3. A first guide block 41 and a second guide block 42 are arranged on both the left and right sides of the running roller 3. Pet toys are installed on the first guide block 41 and the second guide block 42.

[0038] The running roller 3 is made of transparent material.

[0039] The toys on the first inducer block 41 and the second inducer block 42 are not shown in the diagram. The pet toys on the first inducer block 41 and the second inducer block 42 can be set according to the preferences of each pet.

[0040] An induction mechanism is provided on the outer side of the running roller 3 to drive the first induction block 41 and the second induction block 42 to rotate intermittently when the running roller 3 rotates.

[0041] When a pet runs inside the running roller 3, it can drive the running roller 3 to rotate. By setting 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, thereby attracting the pet and making the pet persist in exercising.

[0042] An adjustment mechanism is provided inside the annular outer shell 1 to drive the positioning roller 2, the first guide block 41 and the second guide block 42 to make linear motion.

[0043] By setting an adjustment mechanism, the positioning roller 2, the first guide block 41 and the second guide block 42 can be driven to move away from the center of the annular shell 1 or move closer to the center of the annular shell 1, so that the whole device can be adapted to rollers of different sizes, that is, to pets of different sizes, effectively improving the overall adaptability of the device.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism includes five threaded rods 51 rotatably connected inside the annular housing 1. The five threaded rods 51 are distributed in a circumferential shape inside the annular housing 1. An internal threaded sleeve 52 is fitted on the threaded rod 51 and threadedly connected to it. A bent rod 53 extending to the outside of the annular housing 1 is fixedly connected to the surface of the internal threaded sleeve 52. A straight groove 54 is opened on the surface of the annular housing 1 to allow the bent rod 53 to move and is distributed parallel to the threaded rod 51.

[0045] By setting the straight groove 54, the movement path of the bending rod 53 can be restricted, preventing the bending rod 53 and the inner threaded sleeve 52 from rotating with the threaded rod 51.

[0046] One of the threaded rods 51 is driven by an external motor.

[0047] like Figure 1 and Figure 2 As shown, three bending rods 53 correspond one-to-one with three positioning rollers 2. The positioning rollers 2 are rotatably connected to the free ends of the bending rods 53. The three bending rods 53 have different shapes from the other two bending rods 53. The free ends of the other two bending rods 53 are rotatably connected to the bearing plates 55.

[0048] like Figure 2 As shown, a vertical plate 56 is fixedly connected to the upper surface of the bearing plate 55, and electric telescopic rods 57 are fixedly connected to both opposite sides of the vertical plate 56. The first guide block 41 and the second guide block 42 are respectively installed at the free ends of the two electric telescopic rods 57, and the second guide block 42 is fixedly connected to the electric telescopic rod 57.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, an annular frame 58 is rotatably connected inside the annular shell 1. A first gear 59 is fixed on the surface of the annular frame 58. Each threaded rod 51 has a second gear 510 at its end that meshes with the first gear 59.

[0050] By adopting the above scheme, when one of the threaded rods 51 is driven to rotate by an external motor, it can drive the first gear 59 to rotate through the second gear 510 fixed coaxially with it. Then the first gear 59 can drive the remaining second gears 510 to rotate, so that all the threaded rods 51 can rotate at the same time.

[0051] like Figure 2 As shown, the corresponding first guide block 41 and second guide block 42 form a cylinder. The guiding mechanism includes spiral grooves 61 that are opened on the surfaces of the first guide block 41 and the second guide block 42 and are distributed equidistantly around the circumference. The number of spiral grooves 61 is at least two. A sliding column 62 is inserted into the surface of the running roller 3. The sliding column 62 is adapted to the spiral groove 61.

[0052] When the sliding column 62 rotates with the running roller 3, the sliding column 62 can gradually enter the spiral groove 61 and push the first guide block 41, the second guide block 42 and the support plate 55 to rotate. Then the pet toys installed on the first guide block 41 and the second guide block 42 will also rotate, attracting the pets in motion.

[0053] The running roller 3 has a round hole on its surface for inserting the sliding post 62, and the sliding post 62 can be directly pulled off the running roller 3.

[0054] like Figure 2 and Figure 6 As shown, the edge of the bearing plate 55 is provided with a groove 63. The number of grooves 63 is the same as that of the spiral grooves 61 and they correspond one-to-one. The surface of the running roller 3 is fitted with a positioning frame 64 that is adapted to the groove 63. 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.

[0055] The positioning frame 64 is attached to the running roller 3 and can be directly removed from the running roller 3.

[0056] When the sliding column 62 enters the spiral groove 61, it pushes the first guide block 41 and the second guide block 42 to rotate. Then, as the sliding column 62 disengages from the spiral groove 61, one end of the positioning frame 64 enters the groove 63, limiting the rotation angle of the first guide block 41, the second guide block 42, and the support plate 55.

[0057] like Figure 7 and Figure 8 As shown, a cleaning cloth 7 is fitted onto the surface of the first guiding block 41 and the second guiding block 42.

[0058] Drive the corresponding first guide block 41 and second guide block 42 to move in opposite directions using the electric telescopic rod 57. Then, put the cleaning cloth 7 on the first guide block 41 and second guide block 42. The cleaning cloth 7 can be used for disposable purposes or can be washed and reused multiple times. Then, place the running roller 3 between the two sets of first guide blocks 41 and second guide blocks 42. Drive the first guide block 41 and second guide block 42 to move towards each other using the electric telescopic rod 57, so that the first guide block 41 and second guide block 42 clamp the running roller 3. At this time, manually push the running roller 3 to rotate, so that the dirt on the surface of the running roller 3 is wiped clean by the cleaning cloth 7.

[0059] The cleaning cloth 7 can be used dry or wet.

[0060] Both bearing plates 55 are equipped with resistance mechanisms, and the surface of the first induction block 41 away from the spiral groove 61 has resistance patterns.

[0061] The resistance ripple pattern is not shown in the diagram.

[0062] By setting a resistance mechanism, the first guide block 41 can be driven to rotate 180 degrees, so that the side with the resistance pattern faces the running roller 3.

[0063] When the side of the first guide block 41 with resistance texture abuts against the running roller 3, it can bring a certain resistance to the rotation of the running roller 3, thereby improving the pet's exercise effect. Figure 12 As shown.

[0064] The closer the first guide block 41 is in contact with the running roller 3, the greater the resistance it provides;

[0065] When the pet has a strong desire to move, the first guide block 41 can provide resistance, so there is no need for the pet toy to rotate to induce movement.

[0066] When the first guide block 41 provides resistance, the positioning frame 64 and the sliding column 62 need to be removed from the running roller 3.

[0067] like Figure 9 , Figure 10 and Figure 11 As 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, a third gear 83 fixedly connected to the hollow shaft 82, and a rack 84 vertically fixed to the upper surface of the bearing plate 55.

[0068] The third gear 83 can mesh with the rack 84.

[0069] like Figure 11 As shown, a central shaft 85 is rotatably connected to the upper surface of the circular plate 81. The first guide block 41 is fixedly connected to the upper end of the central shaft 85. A ratchet 86 is fitted on the central shaft 85 and fixedly connected thereto. Several extension rods 87 are fixedly connected to the inner wall of the hollow shaft 82 in a circularly equidistant manner. Each extension rod 87 is rotatably connected to a ratchet 88. The ratchet 88 meshes with the ratchet 86. A spring 89 is fixedly connected to the inner wall of the hollow shaft 82. The other end of the spring 89 is fixed to the surface of the ratchet 88.

[0070] The first inducer block 41 and the second inducer block 42 are both magnetic blocks. The external pet toy also has magnetic blocks that attract each other, so the pet toy can be directly attached to the first inducer block 41 and the second inducer block 42.

[0071] Working principle of the invention:

[0072] When it is necessary to replace the running roller 3 of different sizes, one of the threaded rods 51 is driven to rotate by an external motor. The threaded rod 51 can drive the first gear 59 to rotate through the second gear 510 fixed coaxially with it. Then the first gear 59 can drive the remaining second gears 510 to rotate, so that all the threaded rods 51 can rotate at the same time.

[0073] The threaded rod 51 can drive the internal threaded sleeve 52 and the bending rod 53 to move along the straight groove 54. The three straight grooves 54 can drive the positioning roller 2 to move accordingly, and the other two bending rods 53 can drive the bearing plate 55, the first guide block 41 and the second guide block 42 to move accordingly. Thus, the positioning roller 2, the first guide block 41 and the second guide block 42 can move both away from the center of the annular shell 1 and closer to the center of the annular shell 1.

[0074] After the positioning roller 2, the first guide block 41 and the second guide block 42 move away from the center of the annular shell 1, the running roller 3 is released. Other models of running roller 3 can be placed between the three positioning rollers 2. Then, the positioning roller 2, the first guide block 41 and the second guide block 42 are driven to move closer to the center of the annular shell 1, so that the three positioning rollers 2 press against the surface of the running roller 3, thus completing the replacement of the running roller 3.

[0075] When the pet runs in the running roller 3, the running roller 3 will rotate, which will drive the sliding column 62 to rotate as well. The sliding column 62 can gradually enter the spiral groove 61 and push the first guide block 41, the second guide block 42 and the support plate 55 to rotate. Then the pet toys installed on the first guide block 41 and the second guide block 42 will also rotate, attracting the pet in motion.

[0076] When the sliding column 62 enters the spiral groove 61, it pushes the first guide block 41 and the second guide block 42 to rotate. Then, as the sliding column 62 disengages from the spiral groove 61, one end of the positioning frame 64 enters the groove 63, limiting the rotation angle of the first guide block 41, the second guide block 42, and the bearing plate 55.

[0077] When the running roller 3 needs to be cleaned, the corresponding first guide block 41 and second guide block 42 are moved in opposite directions by the electric telescopic rod 57. Then, the cleaning cloth 7 is put on the first guide block 41 and second guide block 42. The cleaning cloth 7 can be used for disposable purposes or can be washed and reused multiple times. Then, the running roller 3 is placed between the two sets of first guide blocks 41 and second guide blocks 42. The first guide blocks 41 and second guide blocks 42 are moved closer to each other by the electric telescopic rod 57, so that the first guide blocks 41 and second guide blocks 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.

[0078] When the pet is highly motivated to exercise and does not need toys to attract its attention, the electric telescopic rod 57 drives the circular plate 81, the central shaft 85, the first guide block 41, and the third gear 83 to move closer to the upright plate 56 (the electric telescopic rod 57 drives the corresponding second guide block 42 to move and make way). The third gear 83 can gradually mesh with the rack 84 and generate rotation. The third gear 83 can drive the ratchet 88 to rotate through the hollow shaft 82 and the extension rod 87. The ratchet 88 can drive the ratchet 86, the central shaft 85, and the first guide block 41 to rotate, so that the side of the first guide block 41 with the resistance pattern faces the running roller 3.

[0079] When the side of the first guide block 41 with resistance texture abuts against the running roller 3, it can bring a certain resistance to the rotation of the running roller 3, thereby improving the pet's exercise effect. Figure 12 As shown.

[0080] The closer the first guide block 41 is in contact with the running roller 3, the greater the resistance it provides.
