[0011] The utility model is further described below in conjunction with the accompanying drawings:

[0012] Refer to the attached Figure 1 : A spring rocking horse in this embodiment includes a pony body 1, a chassis 2 and a supporting spring 3, the bottom of the supporting spring 3 is fixed on the chassis 2, the top of the supporting spring 3 is fixedly connected to the pony body 1, the chassis 2 is provided with a lifting hole, the lifting hole is provided with a lifting cylinder 4, a manual lifter 5 is provided between the lifting cylinder 4 and the chassis 2, the lifting cylinder 4 is provided with a piston cavity, a piston body 6 is slidably installed in the piston cavity, an elastic supporting body 7 is provided between the piston body 6 and the bottom of the piston cavity, and an elastic rod 8 is fixedly connected between the piston body 6 and the pony body 1.

[0013] Its working principle is to realize the elastic support force or height adjustment of the pony body 1 through the lifting hole and the lifting cylinder 4 on the chassis 2, and the manual lifter 5 enables the user to easily adjust the height of the lifting cylinder 4 as needed. The bottom of the support spring 3 is fixed to the chassis 2, and the top is connected to the pony body 1, ensuring the stability of the rocking horse when bearing load. The piston body 6 slides in the piston cavity in the lifting cylinder 4, cooperates with the elastic support body 7, provides additional support and buffering effect, so that the pony body 1 can quickly return to the initial position through the elastic rod 8 after being stressed, and enhances the resetting performance of the rocking horse. This design not only improves the load capacity and stability of the rocking horse, but also effectively prolongs the service life and reduces the risk of tipping over through the setting of the elastic support body 7 and the elastic rod 8, providing a safer and more durable amusement experience for children.

[0014] The upper end of the lifting cylinder 4 is fixedly provided with a limited end cap 9, which is provided with a center hole 10, and the center hole 10 is clearance-matched with the elastic rod 8. This design is to ensure that the elastic rod 8 can move freely in the center hole 10, and limit its range of motion at the same time, and limit the excessive deviation angle of the elastic rod 8 during the movement of the rocking horse. The clearance match between the center hole 10 and the elastic rod 8 allows the elastic rod 8 to swing within a certain range, which not only provides the necessary activity space for the rocking horse, ensuring that it can smoothly carry out the forward and backward swinging action, but also can absorb and disperse the impact force generated when the children play to a certain extent, thereby protecting the structure of the rocking horse from damage, and increasing the safety and reliability of use. In addition, this limited design also helps to maintain the overall stability of the rocking horse, prevents accidental tipping during use, and ensures the safety of children during use.

[0015] The manual lifter 5 includes a box body 11, a screw rod 12, a labor-saving lever 13, a left slider 14 and a right slider 15. The left slider 14 and the right slider 15 are slidably installed on the inner walls of the left and right sides of the box body 11 respectively. The lifting cylinder 4 is fixedly installed on the left slider 14. The left slider 14 is provided with a left slide groove. The right slider 15 is threadedly connected with the screw rod 12. The right slider 15 is provided with a right slide groove. The screw rod 12 is rotatably installed on the right part of the box body 11 and is located outside the support spring 3. An adjusting handwheel is fixedly installed on the upper end of the screw rod 12. The labor-saving lever 13 is rotatably installed in the box body 11. The left and right ends of the labor-saving lever 13 are provided with axle pins, and the two axle pins are respectively movably hinged with the left slide groove and the right slide groove.

[0016] The manual lifter 5 is used to adjust the height of the lifting cylinder 4. Through this design, when the user rotates the adjustment hand wheel, the screw rod 12 rotates, thereby driving the right slider 15 to move up and down, and the axle pin at the right end of the labor-saving lever 13 moves in the right slide groove. Through the transmission of the labor-saving lever 13, the axle pin at the left end of the labor-saving lever 13 moves accordingly in the left slide groove, driving the left slider 14 to slide, and the lifting cylinder 4 moves up and down, thereby adjusting the height of the lifting cylinder 4 or the pony body 1. The advantage of this design is that through the mechanical advantage of the labor-saving lever 13, the user can adjust the height more easily, reducing the force required during operation and improving the convenience of use. At the same time, the design of the screw rod 12 and the slider ensures the accuracy and stability of the height adjustment, so that the rocking horse remains stable during the adjustment process, providing users with a safe and reliable operating experience.

[0017] A protective bellows 16 is fixedly installed between the pony body 1 and the chassis 2, and the support spring 3 is located in the protective bellows 16. This design plays multiple roles. First, the protective bellows 16 provides an additional protective layer to prevent the support spring 3 from being directly hit or damaged by external objects during operation, and also has rain and dustproof effects, thereby ensuring the integrity and functionality of the spring. Secondly, when the support spring 3 is located in the protective bellows 16, it can effectively prevent the spring from clamping the legs during the use of the rocking horse, thereby ensuring the safety of children when using the rocking horse. In addition, the design of the protective bellows 16 also helps to reduce the noise and vibration generated by the support spring 3 during movement, thereby improving the user experience of the rocking horse. The flexibility of the bellows allows the spring to freely expand and contract inside it, while maintaining the overall structural stability, and will not cause the instability of the rocking horse body due to the movement of the spring. While improving the durability and safety of the rocking horse, this design also takes into account the user's comfortable experience, reflecting the designer's careful consideration of product details and the high attention to children's safety.

[0018] The elastic support body 7 is one of an auxiliary spring, an elastic telescopic air cushion and a high-resilience rubber sponge. The material selection of the elastic support body 7 affects the comfort and durability of the spring rocking horse. By using one of an auxiliary spring, an elastic telescopic air cushion or a high-resilience rubber sponge as the elastic support body 7, additional cushioning and supporting effects can be effectively provided, thereby enhancing the stability and comfort of the rocking horse during use.

[0019] The auxiliary spring can provide stable elastic support to help the piston body 6 move smoothly inside the piston cavity and reduce damage caused by impact. The elastic telescopic air cushion can absorb more impact force due to its softness and adaptability, providing the user with a softer rebound feeling. The high-rebound rubber sponge can maintain good performance after long-term use due to its good resilience and durability.

[0020] The selection of these materials not only increases the life of the rocking horse, but also ensures the safety and comfort of children when using it, so that the rocking horse can still maintain good performance and structural integrity when subjected to repeated loads. Through this careful material selection and design, the spring rocking horse can better meet the needs of children's entertainment while ensuring the reliability and durability of the product.
