Description

Technical Field

[0001] The invention belongs to the technical field of toys, and in particular relates to a bionic deformable tadpole toy. Background Art

[0002] Frog toys with internal mechanisms currently on the market can be roughly divided into two categories: the first retains the frog's legs and feet, using torsion springs or springs as a power source, and employing a mechanism consisting of gears and connecting rods to achieve the frog's bouncing effect. The second replaces the frog's legs with wheels, driving the wheels to achieve overall movement.

[0003] An analysis of the internal mechanisms of commercially available frog toys reveals that these mechanisms only allow for a single form; neither wheeled locomotion nor leg-based jumping can achieve the desired form transition. Frogs, as amphibian-like creatures of the order Anura, are best known for their metamorphosis from tadpole to frog. As important tools for guiding infants and young children in their understanding of the world, toys must objectively reflect reality. Frog toys with wheels alter the movement characteristics of frogs in real environments and fail to objectively reflect how they move. Frog toys with legs and feet cannot depict the tadpole stage. Summary of the Invention

[0025] The present invention discloses a toy that switches between a frog and a tadpole. The toy comprises a housing 1, as shown in the figure. The housing 1 has a receiving cavity 2 with an open bottom. In this embodiment, the receiving cavity 2 is used to accommodate components such as a front leg rod 3 and a rear leg rod 4. The front leg rod 3 and the rear leg rod 4 extend and retract into the housing 1 at the open bottom.

[0026] The trunk 5 forms a linear sliding connection with the housing 1. As shown in the figure, the end of the trunk 5 is sleeved with a slide groove 6, with which the trunk 5 is slidably connected. The slide groove 6 is fixed to the housing 1. The slide groove 6 guides the trunk 5, allowing the trunk 5 to move linearly along the length of the slide groove 6. Typically, the end of the trunk 5 is provided with a mounting cavity 7, into which one end of a compression spring 8 is inserted, while the other end of the compression spring 8 is exposed outside the mounting cavity 7 and abuts against the housing 1.

[0027] The tail end of the trunk 5 has a tail portion 9. In specific applications, the tail portion 9 moves along with the trunk 5. In this embodiment, the tail portion 9 is tapered. In another embodiment, the tail portion 9 can also adopt other shapes.

[0028] The housing 1 is provided with a passage 10 for the tail portion 9 to pass through. When the tail portion 9 moves along with the trunk 5 , the tail portion 9 can extend out of the passage 10 and be exposed outside the housing 1 , or can be retracted into the passage 10 .

[0029] The front leg rod 3 is hinged to the trunk rod 5. The front leg rod 3 is provided with a first through slot 11, and a fixed first fixing rod 12 is provided in the first through slot 11, and the first fixing rod 12 is slidable relative to the first through slot 11 along the length direction of the first through slot 11.

The rear leg rod 4 is also rotatably connected to the shell 1 through the third fixing rod 20. In a specific application process, during the period when the rear leg rod 4 is extended and retracted into the shell, the rear leg rod 4 rotates relative to the shell 1 with the third fixing rod 20 as the axis, thereby causing the rear leg rod 4 to extend or retract into the shell 1. The trunk rod 5 has a first position and a second position in its sliding direction, and the trunk rod 5 can be moved and switched between the first and second positions. When the trunk rod 5 is in the first position, the front leg rod 3 and the rear leg rod 4 both extend out of the housing 1, and the tail 9 retracts into the housing 1; when the trunk rod 5 is in the second position, the front leg rod 3 and the rear leg rod 4 both retract into the housing 1, and the tail 9 extends out of the housing 1. As shown in the figure, the trunk rod 5 is provided with a pin 21, and the housing 1 is provided with a first locking hole 22 and a second locking hole 23; when the pin 21 is inserted into the first locking hole 22, the trunk rod 5 is in the first position; when the pin 21 is inserted into the second locking hole 23, the trunk rod 5 is in the second position.

[0030] In this embodiment, the hind leg rod 4 includes an upper rod 15, a lower rod 16, a palm portion 17, a first torsion spring 18, and a second torsion spring 19. The second through-slot 14 is provided in the upper rod 15. The upper rod 15 is hinged to one end of the lower rod 16. One end of the first torsion spring 18 is fixedly connected to one end of the upper rod 15, and the other end of the torsion spring is fixedly connected to one end of the lower rod 16.
