[0003] Existing pet treadmills have three drawbacks: First, they are complex and time-consuming to assemble. Second, adjusting the dog leash is complicated and inconvenient. Third, they are very noisy, causing disturbance to neighbors. Currently, treadmills on the market suffer from long assembly times and complex assembly processes due to cost considerations for transportation. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pet treadmill that can be folded as a whole, making it easy for consumers to use, and the position of the dog leash can be adjusted with one hand.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pet treadmill, including a running platform, and also including

[0007] The guardrail, rotatably connected to both sides of the running platform, is used to protect the pet running on the platform. It includes at least one rotatable link and two uprights. The first end of the upright is pivotally connected to the running platform, and the second end is pivotally connected to the link. The uprights, the running platform and the link are interconnected to form a deformable four-bar structure.

[0008] The column is supported on the ground, so that the running platform is in a gap with the ground;

[0009] Adjustable support member, with its two ends respectively connected to the two guardrails;

[0010] A positioning part is provided on the guardrail, and the positioning part has a plurality of limiting holes distributed circumferentially; and

[0011] A release device is provided on the adjusting support member. The release device can selectively engage with one of the plurality of limiting holes to fix the angular position of the adjusting support member. The adjusting support member can drive the guardrail to rotate to a position flush with the running platform.

[0012] Furthermore, the guardrail includes at least two posts, the first end of the two posts is pivotally connected to the running platform, and the second end is pivotally connected to the connecting rod. The two ends of the running platform are staggered at different heights. The two posts and the connecting rod are pivotally connected to each other to form a deformable frame.

[0013] Furthermore, a detachable fastener is provided between the column and the running platform. After the fastener is removed, the column can rotate relative to the running platform.

[0014] Furthermore, the tripping device includes a limiting member, which is slidably connected within the adjusting support member. An elastic member is provided between the limiting member and the adjusting support member, and the limiting member is partially engaged within the limiting hole by the elastic force of the elastic member.

[0015] Furthermore, the outer side of the limiting member located inside the limiting hole is provided with a guide slope.

[0016] Furthermore, the adjusting support is provided with a first sliding hole, which is arranged along the length direction of the adjusting support. The connecting rod is provided with a pivot shaft, which is slidably connected in the first sliding hole. The adjusting support can rotate around the pivot shaft.

Detailed Implementation

[0035] The following is combined with Figure 1-8 This utility model will be described in detail.

[0036] A pet treadmill, such as Figure 1 As shown, the device includes a running platform 10 and a guardrail 20, which is rotatably connected to both sides of the running platform 10 to protect pets running on the platform. The guardrail includes at least one rotatable link 202 and two uprights 201. The first end of the upright 201 is pivotally connected to the running platform 10, and the second end is pivotally connected to the link 202. The uprights 201, the running platform 10, and the link 202 are interconnected to form a deformable four-bar structure. The shape of the guardrail 20 can be changed by rotating the link 202. The guardrail 20 can be rotated to put the treadmill into a normal state or a folded state. In the normal state, the guardrail 20 is upright and unfolded to form a protective space, and the pet can use the treadmill normally. In the folded state, the guardrail 20 is rotated and flattened to be flush with the running platform 10, and the overall structure is folded up to save space.

[0037] The column 201 is supported on the ground, creating a gap between the running platform 10 and the ground. The bottom of the column 201 supports the ground, causing the running platform 10 to be suspended in the air.

[0038] An adjusting support 30 is provided, with its two ends connected to the two guardrails 20 respectively. The adjusting support 30 can be fixed to the guardrails 20 so as to drive the guardrails 20 to rotate relative to the running platform 10. The adjusting support 30 can also rotate and slide relative to the guardrails 20, and the adjusting support 30 can drive the guardrails 20 to rotate to a position flush with the running platform 10.

[0039] Positioning part 40, provided on guardrail 20, having a plurality of limiting holes 401 distributed circumferentially; and

[0040] A tripping device is provided on the adjusting support 30. The tripping device can selectively engage with one of the plurality of limiting holes 401 to fix the angular position of the adjusting support 30. Pulling up the adjusting support 30 can disengage the tripping device from the limiting hole 401, allowing the adjusting support 30 to rotate around its axis. Pulling up the adjusting support 30 can release the constraint of the tripping device engaging with the limiting hole 401, allowing the adjusting support 30 to rotate around its axis; pressing down the adjusting support 30 can re-engage the tripping device with the limiting hole 401, locking the adjusting support 30 at a specific angle.

[0041] In this embodiment, as Figure 2-3 As shown, the guardrail 20 includes at least two posts 201. The first end of the two posts 201 is pivotally connected to the running platform 10, and the second end is pivotally connected to the connecting rod 202. The two ends of the running platform 10 are staggered in height. The two posts 201, the running platform 10 and the connecting rod 202 are pivotally connected to each other to form a deformable four-bar structure.

[0042] The guardrails 20 are symmetrically distributed on the left and right sides of the running platform 10. The first end of each of the two uprights 201 is near the ground and is hinged to the side of the running platform 10 via a pivot, allowing the uprights 201 to swing back and forth. The second end is the top end and is hinged to the connecting rod 202 via another pivot. The rotatable connecting rod 202 is horizontally positioned, with both ends hinged to the second ends of the uprights 201 on both sides, forming a deformable four-bar frame 202. The connection between the uprights 201 and the running platform 10 is equipped with a detachable fastener, which is a pin or quick-release bolt. After removal, the uprights 201 can be laid completely flat.

[0043] In this embodiment, a detachable fastener is provided between the column 201 and the running platform 10. After the fastener is removed, the column 201 can rotate relative to the running platform 10.

[0044] In this embodiment, as Figure 4-6 As shown, the tripping device includes a limiting member 402, which is slidably connected within the adjusting support member 30. An elastic member 403 is provided between the limiting member 402 and the adjusting support member 30. The limiting member 402 is partially engaged within the limiting hole 401 by the elastic force of the elastic member 403. Furthermore, the outer surface of the limiting member 402 within the limiting hole 401 is provided with a guide slope.

[0045] The tripping device is integrated inside both ends of the adjusting support 30, including a limiting member 402 that can slide radially along the adjusting support 30, with the head designed as a guide slope; and an elastic member 403 that continuously presses the limiting member 402 to extend outward.

[0046] In this embodiment, as Figure 5 As shown, the adjusting support 30 is provided with a first sliding hole 301, which is arranged along the length direction of the adjusting support 30. The connecting rod 202 is provided with a pivot shaft 2021, which is slidably connected in the first sliding hole 301. The adjusting support 30 can rotate around the pivot shaft 2021.

[0047] The adjusting support 30 has elongated first sliding holes 301 at both ends. The connecting rods 202 of the side rails 20 are equipped with pivot shafts 2021, which pass through the first sliding holes 301 to form a sliding pair. The adjusting support 30 can slide along and rotate around the pivot shaft 2021, adapting to positional changes during folding through the cooperation of the sliding holes and the pivot shaft 2021. The adjusting support 30 is a dog leash bar, used to guide the dog running on the platform 10 and prevent it from falling; it has a U-shaped structure. Both ends are connected to the upper middle part of the side columns 201 via the pivot shafts 2021, allowing the adjusting support 30 to rotate around the pivot shafts 2021.

[0048] In this embodiment, the positioning part 40 is an adjusting plate, and a plurality of limiting holes 401 are arranged at equal angles around the pivot shaft 2021 in the circumferential direction. The positioning part 40 is an adjusting plate fixed to the outside of the connecting rod 202, and its center is coaxial with the pivot shaft 2021. A plurality of limiting holes 401 are evenly distributed along the circumferential direction on the edge of the adjusting plate.

[0049] With the release device in the unlocked state: When the user pulls the adjusting support 30 upwards, the guide slope of the limiting member 402 is constrained by the pressure of the positioning hole wall, causing the limiting member 402 to slide inwards and compress the elastic member 403, completely disengaging the limiting member 402 from the limiting hole 401. At this time, the adjusting support 30 can rotate freely around the pivot shaft 2021. The adjusting support 30 has first sliding holes 301 at both ends, allowing the pivot shaft 2021 to slide slightly along the length of the rod to compensate for frame deformation.

[0050] When the release device is in the locked state: after rotating to the target angle, the adjusting support 30 is released, the elastic element 403 pushes the limiting element 402 to pop out, and the head of the limiting element 402 is inserted into the corresponding limiting hole 401, thus fixing the angle of the handrail.

[0051] In this embodiment, the top of the adjusting support 30 is provided with a hook 302. The hook 302 is used to attach to a pet leash.

[0052] In this embodiment, as Figure 8 As shown, the running platform 10 includes a support frame 101, with pedals 102 fixed at both ends of the support frame 101, and a plurality of running rollers 103 rotatably connected between the two pedals 102.

[0053] In this embodiment, the running platform 10 also includes a running belt 104, which is connected to the running roller 103 and the tension roller 501 respectively.

[0054] The support frame 101 is elongated, with pedals 102 fixed to its front and rear ends, forming an inclined motion surface with the front lower than the rear. Several parallel running rollers 103 are installed between the two pedals 102, and the running rollers 103 are rotatably connected to the support frame 101 via bearings. The running belt 104 surrounds all the running rollers 103 to form a closed-loop transmission surface, on which the pet moves.

[0055] In this embodiment, the end of the support frame 101 is provided with a tensioning device, which includes a support rod 502 and a tensioning roller 501 rotatably connected to the support rod 502; the support frame 101 is provided with a second sliding hole along the length direction, and the support rod 502 is slidably connected in the second sliding hole.

[0056] In this embodiment, the tensioning device includes an adjusting bolt 503, which is arranged along the second sliding hole. The support rod 502 is provided with an adjusting hole that matches the adjusting bolt 503. The position of the support rod 502 relative to the second sliding hole is controlled by rotating the adjusting bolt 503.

[0057] The tensioning device includes a support rod 502 located at the end of the support frame 101. The support rod 502 can slide laterally along a second sliding hole on the support frame 101. A tensioning roller 501 is mounted on the support rod 502, and the running belt 104 passes over its surface. An adjusting bolt 503 passes through the support frame 101, and its threaded section engages with the adjusting hole of the support rod 502.

[0058] The adjustment process of the tensioning device includes: rotating the adjusting bolt 503, which drives the support rod 502 to move along the second sliding hole, causing the tension roller 501 to move away from or closer to the running roller 103. When the support rod 502 moves outward, the running belt 104 is stretched and tightened; when the support rod 502 moves inward, the tension on the running belt 104 is released. The tension roller 501 rotates freely on the support rod 502, reducing frictional loss of the running belt 104.

[0059] The pet treadmill of this utility model is used as follows:

[0060] like Figure 7 As shown, disassemble the detachable fastener at the connection between the upright 201 and the running platform 10 to release the root constraint of the upright 201. Pull up the adjusting support 30 to unlock the release device. Push the upright 201 forward or backward, and the upright 201 will rotate around the pivot of the running platform 10. The connecting rod 202 will retract accordingly, and the entire guardrail 20 will be pressed against and flattened against the surface of the running platform 10. The flattened guardrail 20 and the adjusting support 30 are stacked in a compact form, significantly reducing the volume.

[0061] Furthermore, because the adjustable support 30 can rotate the guardrail 20 relative to the running platform 10, the guardrail 20 can be rotated to a position flush with the running platform 10. Without the adjustable support 30, when the guardrail 20 is rotated to a position close to the running platform 10, it could potentially pinch the user's fingers.

[0062] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
