Description

Technical Field

[0001] This utility model belongs to the field of swing technology, specifically a swing that is easy to adjust and use. Background Technology

[0002] A swing is a traditional amusement facility that uses ropes or chains to suspend a seat and generates reciprocating motion through the swinging of the human body. Its simple structure provides a fun experience of dynamic balance. Originating as a hunting tool of ancient northern ethnic minorities, it gradually evolved into a folk entertainment activity. Today, it is widely used in children's playgrounds, parks, and community fitness areas, becoming a common choice for public leisure and relaxation. The application of swings is not limited to entertainment, but has also expanded to sports competitions (such as swinging being included in the traditional sports games of ethnic minorities) and rehabilitation therapy (training balance and muscle coordination through regular swinging). Existing swings mostly rely on the natural swinging of the human body or fixed counterweights, lacking mechanical speed adjustment mechanisms. This results in the swing speed not being able to be flexibly adjusted according to user needs (such as children swinging slowly and adults swinging quickly) or changes in the scene, which limits the user experience and functional expandability. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a swing that is easy to adjust and use, which effectively solves the problem that existing swings mostly rely on the natural swing of the human body or fixed counterweights and lack a mechanical speed adjustment mechanism, resulting in the swing speed not being able to be flexibly adjusted according to user needs or changes in the scene.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a swing that is easy to adjust and use, comprising a main body, with support legs fixedly installed at both ends of the bottom of the main body, a protective cover fixedly installed at the top of the main body, a support frame fixedly installed at the middle of the bottom of the main body, a servo motor fixedly installed at the top inside the protective cover, a shaft rotatably installed at the lower part inside the main body, a cavity opened at the upper part inside the main body, fixed sleeves fixedly installed at both ends of the surface of the shaft, hanging rods fixedly installed at the lower parts of the two fixed sleeves, a seat fixedly installed between the bottom ends of the two hanging rods, the output end of the servo motor extending into the cavity and having a transmission component, two brake discs fixedly installed on the surface of the shaft, brake rings provided on the side of the two brake discs that are close to each other, and both brake rings are sleeved on the surface of the shaft, the transmission component is connected to the two brake rings, when the servo motor is running, the power is output to the two brake rings through the transmission component, causing the two brake rings to move in opposite directions and gradually press against the brake discs to limit the swing speed of the seat.

[0005] Preferably, the transmission assembly includes a driving bevel gear fixedly installed at the output end of the servo motor, a driven bevel gear meshing with one side of the surface of the driving bevel gear, a connecting rod fixedly installed in the middle of the driven bevel gear, threaded rods fixedly installed at both ends of the connecting rod, the ends of the two threaded rods that are far apart from each other being rotatably connected to the inner bottom of the cavity through a positioning seat, and threaded sleeves threadedly connected to the surfaces of the two threaded rods.

[0006] Preferably, a connecting frame is fixedly installed at the bottom of each threaded sleeve, and a collar is fixedly installed inside each of the two connecting frames. The two collars are fitted onto the surface of the shaft. Four sliding sleeves are fixedly installed circumferentially at equal intervals on the surface of each of the two collars. A sliding rod is inserted inside each sliding sleeve, and one end of each of the four adjacent sliding rods is fixedly connected to two brake rings. A spring is fitted onto the surface of each sliding rod, and both ends of the spring are fixedly connected to the brake rings and the sliding sleeves, respectively.

[0007] Preferably, the upper part of the threaded sleeve is fixedly installed with an upper slider by a fixing block, and two upper sliding grooves are opened in the upper part of the cavity. The two upper sliders are slidably installed in the two upper sliding grooves. The bottom of the connecting frame is fixedly installed with a lower slider by a connecting block. The inner bottom of the support frame is opened with two lower sliding grooves, and the two lower sliders are slidably installed in the two lower sliding grooves.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the servo motor to drive the active bevel gear to rotate. The active bevel gear drives the connecting rod to rotate through the driven bevel gear. The connecting rod drives the two threaded rods to rotate along the two positioning seats. When the two threaded rods rotate, they drive the two threaded sleeves to move in opposite directions. When the threaded sleeves move, they drive the upper slider to slide inside the upper groove through the fixed block, which increases the stability of the threaded sleeves when they move. When the two threaded sleeves move in opposite directions, they drive the two brake rings to move in opposite directions and contact the two brake discs through the two connecting brackets. When the connecting brackets move, they drive the lower slider to slide inside the lower groove through the connecting block, which increases the stability of the connecting brackets when moving. The friction between the two limits the rotation speed of the shaft. When the two connecting brackets continue to move in opposite directions, they will drive the two brake rings to squeeze the two brake discs, so that the two brake rings will drive the four slide rods to slide along the inside of the sliding sleeve, and at the same time compress the springs. Because the springs are compressed, the movement of the brake rings is restricted, thereby increasing the stiffness of the brake rings, so that the brake rings can make more forceful contact with the brake discs, thereby increasing the friction and further limiting the rotation speed of the shaft, so as to reduce the swing speed of the seat and make it suitable for different users. This allows the swing speed to be adjusted according to the usage needs of different people, so as to flexibly adjust to different needs or changes in scenarios. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0012] Depend on Figures 1 to 4The present invention includes a device body 1, with support legs 2 fixedly installed at both ends of the bottom of the device body 1, a protective cover 3 fixedly installed at the top of the device body 1, a support frame 9 fixedly installed at the middle of the bottom of the device body 1, a servo motor 5 fixedly installed inside the top of the protective cover 3, a shaft 4 rotatably installed inside the lower part of the device body 1, a cavity opened in the upper part of the device body 1, fixing sleeves 6 fixedly installed at both ends of the surface of the shaft 4, hanging rods 7 fixedly installed at the lower part of the two fixing sleeves 6, and a swinging mechanism for riding fixedly installed between the bottom ends of the two hanging rods 7. The seat 8 has an output end of the servo motor 5 extending into the cavity and equipped with a transmission assembly. Two brake discs 28 are fixedly mounted on the surface of the shaft 4. Each brake disc 28 has a brake ring 26 on one side that is close to the other. The brake ring 26 contacts the brake disc 28 to generate friction. Both brake rings 26 are fitted onto the surface of the shaft 4. The transmission assembly is connected to the two brake rings 26. When the servo motor 5 is running, it outputs power to the two brake rings 26 through the transmission assembly, causing the two brake rings 26 to move in opposite directions and gradually press against the brake disc 28 to limit the swing speed of the seat 8.

[0013] When in use, the operator starts the servo motor 5 to drive the transmission component to rotate. When the transmission component rotates, it drives the two brake rings 26 to move in opposite directions and contact the two brake discs 28. The friction between the two limits the rotation speed of the shaft 4. When the transmission components are running continuously, the brake ring 26 can make more forceful contact with the brake disc 28 to increase friction, thereby further limiting the rotation speed of the shaft 4 and reducing the swing speed of the seat 8, making it suitable for different users; this allows the swing speed to be adjusted according to the usage needs of different people, so as to flexibly adjust to different needs or scene changes.

[0014] The transmission assembly includes a drive bevel gear 10 fixedly mounted on the output end of the servo motor 5. A driven bevel gear 11 is meshed with one side of the surface of the drive bevel gear 10. A connecting rod 12 is fixedly mounted in the middle of the driven bevel gear 11. Threaded rods 13 are fixedly mounted at both ends of the connecting rod 12. The ends of the two threaded rods 13 that are far apart from each other are rotatably connected to the bottom of the cavity through a positioning seat 15. Threaded sleeves 14 are threadedly connected to the surfaces of the two threaded rods 13. The threads of the two threaded rods 13 are opposite in direction, causing the two threaded rods 13 and the two threaded sleeves 14 to move in opposite directions.

[0015] The operator starts the servo motor 5 to drive the active bevel gear 10 to rotate. The active bevel gear 10 drives the connecting rod 12 to rotate through the driven bevel gear 11. The connecting rod 12 drives the two threaded rods 13 to rotate along the two positioning seats 15. When the two threaded rods 13 rotate, they drive the two threaded sleeves 14 to move in opposite directions.

[0016] A connecting bracket 19 is fixedly installed at the bottom of each threaded sleeve 14. A collar 23 is fixedly installed inside each of the two connecting brackets 19, and the two collars 23 are fitted onto the surface of the shaft 4. Four sliding sleeves 24 are fixedly installed circumferentially at equal intervals on the surface of each of the two collars 23. A sliding rod 25 is inserted into the inside of each sliding sleeve 24, so that the sliding rod 25 can move inside the sliding sleeve 24. One end of each of the four adjacent sliding rods 25 is fixedly connected to two brake rings 26. A spring 27 is fitted onto the surface of each sliding rod 25, and both ends of the spring 27 are fixedly connected to the brake ring 26 and the sliding sleeve 24, respectively.

[0017] When the two threaded sleeves 14 move in opposite directions, they both drive the two brake rings 26 to move in opposite directions and contact the two brake discs 28 through the two connecting brackets 19. The friction between them limits the rotation speed of the shaft 4. When the two connecting brackets 19 continue to move in opposite directions, they will drive the two brake rings 26 to squeeze the two brake discs 28, so that the two brake rings 26 will drive the four slide rods 25 to slide along the inside of the sliding sleeve 24, and at the same time compress the spring 27. Since the spring 27 is compressed, it restricts the movement of the brake rings 26, thereby increasing the stiffness of the brake rings 26, so that the brake rings 26 can contact the brake discs 28 more forcefully to increase the friction, thereby further limiting the rotation speed of the shaft 4 and reducing the swing speed of the seat 8.

[0018] The upper part of the threaded sleeve 14 is fixedly installed with an upper slider 18 by a fixing block 16. The upper part of the cavity has two upper sliding grooves 17. The two upper sliders 18 are slidably installed inside the two upper sliding grooves 17, so that the upper sliders 18 can move within the upper sliding grooves 17. The bottom of the connecting frame 19 is fixedly installed with a lower slider 21 by a connecting block 20. The inner bottom of the support frame 9 has two lower sliding grooves 22. The two lower sliders 21 are slidably installed inside the two lower sliding grooves 22, so that the lower sliders 21 can move within the lower sliding grooves 22.

[0019] When the threaded sleeve 14 moves, the upper slider 18 slides inside the upper groove 17 via the fixed block 16, which increases the stability of the threaded sleeve 14 when it moves; when the connecting frame 19 moves, the lower slider 21 slides inside the lower groove 22 via the connecting block 20, which increases the stability of the connecting frame 19 when it moves.
