Description

A hamster treadmill Technical Field

[0001] This invention relates to the field of equipment technology for pet exercise, and in particular to hamster treadmills. Background Technology

[0002] Existing pet hamsters need to run 20 kilometers a day in the wild, but as pets, they cannot do this. Therefore, treadmills were invented so that hamsters can run even in their pet environment. As disclosed in patent CN201821863820.3, the existing hamster treadmill includes rollers, a pair of support frames, and a base. The base is formed by a base plate and a lid that are fastened together. The support frames are secured to the base by a snap-fit ​​device. The rollers rotate between the support frames. The lower end of each support frame has a slot. The lid of the base has multiple mounting holes. The back edge of each mounting hole has a limiting buckle that defines the mounting position of the support frame and a buckle that connects and engages with the slot at the lower end of the support frame. The support frame is inserted into the mounting hole, snapped into the slot by the buckle, and fixed in place by the limiting buckle. The rollers... It is a circular device. When in use, the hamster walks into the wheel and runs forward, causing the wheel to rotate, keeping the hamster always under the wheel, thus achieving the purpose of running. However, this type of hamster treadmill has several problems. First, the hamster is easily thrown off its feet by the high-speed rotating wheel during running (specifically, when the hamster's running speed decreases, it is thrown from the bottom of the wheel to the upper space inside the wheel due to inertia, and then falls down). Second, due to the wheel technology, the hamster's excrement will accumulate inside the wheel while running, contaminating the running track and seriously affecting the hamster's running and its health. Technical issues

[0003] The purpose of this invention is to provide a hamster treadmill that allows hamsters to easily climb onto the treadmill on their own without being thrown off, and to prevent the accumulation of excrement inside the hamster's wheels while running, thus avoiding any impact on the hamster's health. Technical solutions

[0004] The hamster treadmill of the present invention is implemented as follows: it includes a frame, a running belt mechanism disposed on the frame, and a cover disposed on the running belt mechanism. The running belt mechanism includes several rollers rotatably disposed on the frame and a running belt that circulates along the rollers. The rollers are distributed back and forth and obliquely upward. The upper end of the cover is closed.

[0005] When in use, the hamster enters the running belt mechanism through the bottom inlet of the cover (once the hamster has experienced entering the running belt mechanism through the bottom inlet of the cover, it will know how to enter in the future, and the hamster's running is its own need). To get off the running belt mechanism, simply stop running and exit through the bottom inlet of the cover (when the hamster stops running, the inertia of the running belt mechanism will send the hamster out through the bottom inlet of the cover).

[0006] When the hamster runs, it moves the running belt of the running belt mechanism towards the lower inlet of the cover, and then folds back from below the lower end of the running belt mechanism. The process of the running belt folding back from the lower end of the running belt mechanism is a rotation process that occurs together with the roller. During the rotation, centrifugal force is generated. The hamster's excrement on the running belt is thrown outside the lower end of the running belt mechanism under the action of centrifugal force, thus preventing the accumulation of hamster excrement on the running belt and thus avoiding affecting the hamster's running exercise and hygiene.

[0007] Because of the enclosure, the hamster can only run on the running belt, and it cannot fall off the running belt while under the enclosure.

[0008] The running belt is angled upwards, which can effectively increase the amount of exercise the hamster does while reducing its running speed and preventing it from colliding with the upper opening of the enclosed enclosure.

[0009] Preferably, the frame includes a base, a pair of roller shaft fixing members disposed on the base, several rollers are arranged in a sequential manner between the pair of roller shaft fixing members, the bottom ends of the pair of roller shaft fixing members are rotatably disposed on the base, and the upper parts of the pair of roller shaft fixing members are disposed on the base via a height adjuster. The height adjuster includes a telescopic plate fixing seat with a vertical groove, a telescopic plate that moves up and down on the vertical groove, and a positioning member that positions the telescopic plate in the vertical groove. The upper end of the telescopic plate is hinged to the upper part of the pair of roller shaft fixing members.

[0010] During operation, adjusting the position of the telescopic plate within the vertical groove adjusts the tilt angle of a pair of roller shaft fixing parts, thereby adjusting the tilt angle of the running belt mechanism. Then, the position of the telescopic plate is fixed by the positioning component, thus completing the tilt angle adjustment of the running belt mechanism. Beneficial effects

[0011] Compared with existing technologies, this invention has the advantages of allowing hamsters to easily climb onto the treadmill on their own without being thrown off, and preventing the accumulation of excrement inside the hamster's running wheel, thus avoiding affecting the hamster's hygiene and health.

[0021] The hamster treadmill of the present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] As shown in Figures 1 and 2, the hamster treadmill of the present invention is implemented as follows: it includes a frame 1, a running belt mechanism 2 set on the frame 1, and a cover 3 set on the running belt mechanism 2. The running belt mechanism 2 includes several rollers 201 rotatably set on the frame 1 and a running belt 202 that circulates along the rollers 201. The rollers 201 are distributed back and forth and obliquely upward. The cover 3 is in the shape of an inverted groove. The lower end of the cover 3 is open and the upper end 301 of the cover 3 is closed.

[0023] Preferably, as shown in Figure 8, several rollers 201 are distributed along an arc from bottom to top, so that when the hamster first enters the running belt mechanism 2, the slope is relatively gentle. As the hamster runs upward, the slope will become larger and larger, allowing the hamster to choose its running position in the running belt mechanism 2 to select the amount of exercise it can run. Moreover, it avoids the slope being too large, so that the hamster will quickly slide down when it runs onto the running belt mechanism 2, or the slope being too small, so that the hamster can easily reach the finish line.

[0024] Preferably, as shown in Figures 1, 2, and 5, the frame 1 includes a base 101 and a pair of roller shaft fixing members 102 disposed on the base 101. The roller shaft fixing members 102 are arc-shaped plates. A pair of bearings 203 are disposed inside the roller 201. A shaft 204 passes through the pair of bearings 203. The roller 201 is connected between the pair of roller shaft fixing members 102 via the shaft 204. Several rollers 201 are sequentially arranged between the pair of roller shaft fixing members 102, rotating from bottom to top via the shaft 204. The shaft 204 is inserted into the support hole 103 on the side of the roller shaft fixing member 102. A hinge structure 104 is provided at one end of the base 101. The bottom ends of the pair of roller shaft fixing members 102 are rotatably connected to the hinge structure 104. A height adjuster is provided at the other end of the base 101. 4. The upper part of a pair of roller shaft fixing parts 102 is rotatably connected to the height adjuster 4. The height adjuster 4 includes a telescopic plate fixing seat 402 with a vertical groove 401, a telescopic plate 403 that is moved up and down on the vertical groove 401, and a positioning member 404 that positions the telescopic plate 403 in the vertical groove 401. The positioning member 404 is a screw with a thread through a threaded through hole 405 on the side wall of the vertical groove 401. By the frictional force of the screw pressing on the telescopic plate 403, the telescopic plate 403 is positioned in the vertical groove 401. When the screw is loosened, the positioning effect of the frictional force of the screw pressing on the telescopic plate 403 is lost, and the position of the telescopic plate 403 in the vertical groove 401 can be adjusted. The upper part of a pair of roller shaft fixing parts 102 is rotatably connected to the upper end of the telescopic plate 403.

[0025] Preferably, the vertical groove 401 is arc-shaped, and the center of the arc of the arc-shaped vertical groove 401 is the rotation center of the hinge structure 104. The telescopic piece 403 is arc-shaped to match the arc-shaped vertical groove 401.

[0026] A box 5 is provided at the upper end of the cover 3, and the box 5 extends into the cover. Food is placed in the box 5 to attract the hamster into the cover 3 to eat the food in the box 5. The box 5 is provided to close the upper port 301 of the cover 3.

[0027] Preferably, a U-shaped bottom cover 6 is provided under the running belt 202 to cover the bottom of the running belt mechanism 2, thereby protecting the running belt 202 under the running belt mechanism 2 and preventing it from being chewed up.

[0028] Preferably, as shown in Figure 7, the lower part of the U-shaped bottom cover 6 extends to the lower end of the running belt 202, and the upper part of the U-shaped bottom cover 6 extends to the upper end of the running belt 202, completely covering the bottom of the running belt 202 to prevent the hamster from biting the running belt 202.

[0029] Preferably, as shown in Figure 7, the U-shaped bottom cover 6 is provided with pins 7 on both the upper and lower sides, and the roller shaft fixing component 102 corresponding to the pins 7 is provided with pin lugs 8 on its side. The pins 7 are inserted into the pin lugs 8 so that the U-shaped bottom cover 6 is installed and fixed on the roller shaft fixing component 102, which facilitates disassembly and assembly.

[0030] Preferably, a cover 205 is provided on the roller shaft fixing member 102 at the inlet end of the running belt mechanism 2, which floats toward the running belt 202. The cover 205 covers the lower edge of the running belt 202 to prevent hamsters from chewing it.

[0031] Preferably, as shown in Figure 2, the distance between the two side walls 302 of the inner cavity of the cover 3 is less than the width of the running belt 202. The two outer sides of the cover 3 are provided with outward-flaring edges 303, which are connected to the roller shaft fixing member 102, thus positioning the cover 3 on the running belt mechanism 2. By using a distance between the two side walls 302 of the inner cavity of the cover 3 that is less than the width of the running belt 202, the cover 3 covers the two edges of the running belt 202 to prevent hamsters from chewing on it.

[0032] Preferably, the upper end of the cover 205 extends directly to the lower port of the cover 3, and the lower end of the cover 205 extends directly to the lower fold-back part of the running belt 202. The cover 205, together with the cover 3, covers the two upper edges of the running belt 202 to prevent the hamster from chewing it.

[0033] Preferably, several anti-slip ridges 9 are evenly distributed on the surface of the running belt 202 to prevent the hamster from slipping off the running belt 202 while running.

[0034] Preferably, a boss 10 is provided on the base 101 near the running belt 202 at the entrance of the running belt mechanism 2. The boss 10 is provided so that the hamster can smoothly run into the running belt 202 at the entrance of the running belt mechanism 2 by being raised by the boss 10.

[0035] Preferably, a cover pin 11 is provided on the bottom edge 303 of the cover 3, and a cover pin insertion hole 12 is provided on the roller shaft fixing member 102 corresponding to the cover pin 11.
