Description

Technical Field

[0001] This utility model relates to the field of unicycle technology, and in particular to a unicycle that can maintain balance when parked. Background Technology

[0002] A unicycle, generally speaking, refers to a bicycle with only one wheel and powered by human effort. It combines the characteristics of a bicycle and a unicycle, serving as a tool for both recreation and fitness. Unicycles can improve balance, coordination, and core muscle strength. For those who enjoy challenges and outdoor activities, unicycles are a fun recreational tool. They can also be used as props in some stunt performances or street shows. However, unicycles are prone to tipping over if not properly parked or on uneven ground, leading to damage to the vehicle or surrounding property. Utility Model Content

[0003] This application provides a unicycle that can maintain balance when parked. The unicycle is supported by the cooperation between support member one and support member two when parked, so that it can maintain balance and stability.

[0004] This application provides a unicycle that can maintain balance when parked, including a wheel, a support frame mounted on the wheel bearing, which is U-shaped, a support rod fixedly connected to the upper end face of the support frame, a seat fixedly connected to the upper side of the support rod, and a mud guard fixedly connected to the right side of the upper end face of the support frame, located above the wheel; two mounting seats are fixedly connected to the front right end face of the support frame, with another symmetrically arranged on the rear right end face of the support frame; the mounting seat is U-shaped, and a support component is rotatably connected to it, which can support the unicycle when parked, so that it can maintain balance and stability;

[0005] The support assembly includes support rod one, support rod two, transmission rod, transmission gear, driven gear, and rotating rod;

[0006] Support rod one is rotatably connected to the mounting base via a rotating shaft. A rubber sleeve is fixedly fitted on the outer wall of the rotating shaft on the mounting base. A sliding groove and a mounting groove are opened inside support rod one. The sliding groove and the mounting groove are connected. The width of the mounting groove is 2-3 cm less than the width of the sliding groove. Support rod two is slidably connected in the sliding groove. The upper end face of support rod two is set as an inclined surface, and a rubber pad is adhered thereto. A threaded hole is opened inside support rod two. The rotating rod is set as a threaded rod and is rotatably connected in the threaded hole opened in support rod two. The bottom side of the rotating rod is rotatably connected to the inner wall of the mounting groove. The driven gear is fixedly fitted on the outside of the rotating rod. The transmission gear is located above the driven gear and rotates by meshing with the driven gear through its teeth. The transmission rod is fixedly connected to the front side of the transmission gear. Its front side passes through the front end face of support rod one and extends to its outside. An anti-slip rubber sleeve is fixedly fitted on the outside of the transmission rod. The transmission rod is a smooth round rod and is rotatably connected to support rod one.

[0007] A smooth surface of 9-11cm is reserved on the bottom side of the rotating rod.

[0008] Further, a limiting block 1 is fixedly connected to the front end face of the support frame, and a limiting block 2 is fixedly connected to the front end face of the support rod 1; a magnet 1 is glued and fixed to the upper and lower sides of the right end face of the limiting block 1, and a magnet 2 is fixedly connected to the upper and lower sides of the left end face of the limiting block 2, and the magnet 2 is attracted to the magnet 1.

[0009] Further, a horizontal through hole is opened in the middle of the first limiting block, and a rubber sleeve is fixedly installed inside it; a horizontal threaded hole is opened in the middle of the second limiting block, and the center of the horizontal through hole in the middle of the first limiting block and the center of the horizontal threaded hole in the middle of the second limiting block are located on the same axis.

[0010] A limiting rod is installed between the first limiting block and the second limiting block. The limiting rod is set in two sections, with the lengths of the two sections divided in a 1:1 ratio. The right section is set as a threaded rod, and the left section is set as a smooth round rod. The right section of the limiting rod is rotatably connected to the threaded hole in the second limiting block through the thread, and the left section of the limiting rod is rotatably connected to the through hole in the first limiting block.

[0011] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages: When the unicycle needs to be parked, the limit rod is turned to rotate the support rod one to the right to keep it horizontal. Then, the transmission gear is rotated clockwise through the transmission rod, causing the driven gear to rotate the rotating rod, pushing the support rod two out of the support rod one and adjusting it to a suitable length. Then, the support rod one is rotated again, so that the upper end face of the support rod two contacts the ground, providing support for the unicycle. The cooperation between the support member one and the support member two provides support for the unicycle when it is parked, enabling it to maintain balance and stability. Moreover, the upper end face of the support rod two is set as an inclined surface with an adhesive rubber pad. When the support rod one is rotated to the right, the upper end face of the support rod two can make contact with the ground over a larger area, improving the stability of the unicycle when parked. At the same time, the rubber pad can increase the friction between the support rod two and the ground, further ensuring the stability of the unicycle when parked. Attached Figure Description

[0025] Example 1

[0026] Please see Figure 1-9 A wheelbarrow that can maintain its balance when parked, including wheels 10.

[0027] A support frame 11 is mounted on the bearing of the wheel 10. The support frame 11 is U-shaped. A support rod 13 is fixedly connected to the upper end of the support frame 11. A seat 14 is fixedly connected to the upper side of the support rod 13. A mud guard 12 is fixedly connected to the right side of the upper end of the support frame 11, which is located above the wheel 10. A mounting seat 15 is fixedly connected to the front right end of the support frame 11. There are two mounting seats, and the other one is symmetrically arranged on the rear right end of the support frame 11. The mounting seat 15 is U-shaped and a support component 20 is rotatably connected to it. When the unicycle is parked, it can be supported to keep it balanced and stable.

[0028] The support assembly 20 includes a first support rod 21, a second support rod 23, a transmission rod 28, a transmission gear 27, a driven gear 26, and a rotating rod 25;

[0029] Support rod 1 21 is rotatably connected to mounting base 15 via a rotating shaft. Support rod 1 21 has a sliding groove 22 and a mounting groove 24, and the sliding groove 22 communicates with the mounting groove 24. Support rod 22 23 is slidably connected to the sliding groove 22. The bottom side of rotating rod 25 is rotatably connected to the inner wall of mounting groove 24. Driven gear 26 is fixedly fitted on the outside of rotating rod 25. Transmission gear 27 is located on the upper side of driven gear 26 and rotates by meshing with driven gear 26 through its teeth. Transmission rod 28 is fixedly connected to the front side of transmission gear 27. Its front side passes through the front end face of support rod 1 21 and extends to its outside. Anti-slip rubber sleeve 29 is fixedly fitted on the outside of transmission rod 28.

[0030] A threaded hole is opened in the support rod 23, and the rotating rod 25 is set as a threaded rod. The rotating rod 25 is rotatably connected to the threaded hole opened in the support rod 23. A smooth surface of 9-11cm is reserved on the bottom side of the rotating rod 25 for the installation of the driven gear 26.

[0031] The transmission rod 28 is a smooth round rod, which is rotatably connected to the support rod 21.

[0032] The width of the mounting groove 24 is 2-3cm smaller than the width of the sliding groove 22, which can limit the bottom side of the support rod 23 and prevent the bottom side of the support rod 23 from hitting the driven gear.

[0033] The upper surface of the second support rod 23 is set as an inclined surface, and a rubber pad is attached thereto. When the support rod 21 rotates to the right, the upper surface of the second support rod 23 can make contact with the ground over a larger area, which improves the stability of the unicycle when it is parked. Moreover, the rubber pad can increase the friction between the second support rod 23 and the ground, further ensuring the stability of the unicycle when it is parked.

[0034] To prevent the support component 20 from obstructing the unicycle's movement during riding, a first limiting block 40 and a second limiting block 30 are designed. Through the cooperation between the first limiting block 40 and the second limiting block 30, the support component 20 can be fixed on the support frame 11.

[0035] Limiting block 40 is fixedly connected to the front end face of support frame 11. Magnet block 42 is glued and fixed on the upper and lower sides of the right end face of limiting block 40. Limiting block 30 is fixedly connected to the front end face of support rod 11. Magnet block 31 is fixedly connected on the upper and lower sides of the left end face of limiting block 30. Magnet block 31 and magnet block 42 are attracted to each other.

[0036] Limiting block 1 40 has a transverse through hole in the middle, and a rubber sleeve is fixedly installed inside it; Limiting block 2 30 has a transverse threaded hole in the middle, and a limiting rod 41 is installed between limiting block 1 40 and limiting block 2 30.

[0037] The center of the transverse through hole in the middle of limit block 1 40 and the center of the transverse threaded hole in the middle of limit block 2 30 are on the same axis.

[0038] The limiting rod 41 is set in two sections, with the lengths of the two sections divided in a 1:1 ratio; the right section is set as a threaded rod, and the left section is set as a smooth round rod;

[0039] The right section of the limiting rod 41 is rotatably connected to the threaded hole of the limiting block 2 30 via a thread, and the left section of the limiting rod 41 is rotatably connected to the through hole of the limiting block 1 40 (the installation of the rubber sleeve can appropriately increase the friction between the limiting rod 41 and the limiting block 1 40, so that the rotation of the limiting rod 41 requires a certain amount of manual force, thus preventing the limiting rod 41 from falling off the limiting block 1 40 after the support rod 1 21 rotates with the limiting block 2 30).

[0040] Similarly, the outer wall of the rotating shaft on the mounting base 15 is fixed with a rubber sleeve. The installation of the rubber sleeve can appropriately support the friction between the support rod 21 and the mounting base 15, so that the rotation of the support rod 21 requires a certain amount of human power. In this way, when the support rod 23 supports the unicycle, it can prevent the support rod 21 from rotating arbitrarily, thereby ensuring the stability of the unicycle when it is parked.

[0041] It should be noted that limit block 1 40 and limit block 2 30 are symmetrically arranged on the rear end face of support frame 11, thereby achieving support on both the front and rear sides of the unicycle and further improving the stability of the unicycle when it is parked.

[0042] In actual operation of this embodiment, when the unicycle needs to be stopped, the limiting rod 41 is turned to rotate the support rod 21 to the right to keep it horizontal. Then, the transmission gear 27 is rotated clockwise through the transmission rod 28, causing the driven gear 26 to rotate the rotating rod 25, pushing the support rod 23 out of the support rod 21 and adjusting it to a suitable length. Then, the support rod 21 is rotated again so that the upper surface of the support rod 23 contacts the ground, providing support for the unicycle. When the unicycle needs to be ridden, the support rod 23 is retracted into the support rod 21, and then the support rod 21 is turned to the left. The magnet 42 and the magnet 31 attract each other, thus positioning the limiting block 40 and the limiting block 30. Then, the limiting rod 41 is rotated to screw it into the threaded hole in the limiting block 30 to fix the support rod 21.

[0043] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: the cooperation between support member one and support member two can support the unicycle when it is parked, enabling it to maintain balance and stability; moreover, the upper end face of support member two is set as an inclined surface, with an adhesive rubber pad, which allows the upper end face of support member two to contact the ground with a larger area when support member one rotates to the right, improving the stability of the unicycle when parked. At the same time, the rubber pad can increase the friction between support member two and the ground, further ensuring the stability of the unicycle when parked.

[0044] The unicycle in this application is structurally similar to existing unicycles.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
