[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 A multi-layer composite PVC inflatable inner liner for decorative toys, including an inner liner body 1, an air vent 2 provided at the limb connection of the inner liner body 1, and a rocking mechanism provided inside the limb of the inner liner body 1.

[0026] The rocking mechanism includes connecting rods 3 that correspond one-to-one with the limbs of the inner liner body 1. A connecting port 4 is provided on one side of the connecting rod 3. A connecting shaft 5 is rotatably connected to the inner wall of the connecting port 4 through a bearing. A rocking rod 6 is fixedly connected to one side of the connecting shaft 5. A rocking head 7 is fixedly connected to the side of the rocking rod 6 away from the connecting rod 3. The rocking head 7 has a spherical structure.

[0027] As a further improvement of this utility model, a T-shaped connecting groove 8 is provided on one side of the connecting rod 3, and a T-shaped connecting block 9 is slidably connected to the inner wall of the connecting groove 8. A connecting plate 10 is hinged to one side of the connecting block 9, and the connecting plate 10 is hinged to the rocker arm 6.

[0028] Specifically, by sliding the connecting block 9 in the inner wall of the connecting groove 8 and cooperating with the connecting shaft 5 in the inner wall of the connecting port 4, the angle between the rocker arm 6 and the connecting rod 3 can be changed, which in turn changes the angle between the connecting plate 10 and the rocker arm 6.

[0029] As a further improvement of this utility model, a connecting spring 11 is fixedly connected to one side of the connecting block 9, and one side of the connecting spring 11 is fixed to the inner wall of the connecting groove 8.

[0030] Specifically, the elastic force of the connecting spring 11 can apply force to the connecting block 9, which can make the connecting block 9 slide in the inner wall of the connecting groove 8, and change the angle between the connecting plate 10 and the rocker arm 6. This can be combined with the rocker head 7 to apply different forces to the inner wall of the limbs of the inner liner body 1, so that the limbs of the inner liner body 1 can be in a rocking state.

[0031] As a further improvement of this utility model, the inner wall of the vent 2 is provided with a positioning ring 12 in the form of a circular ring, and a positioning frame 13 is fixedly connected to the inner wall of the positioning ring 12. One side of the positioning frame 13 is fixedly connected to one side of the connecting rod 3.

[0032] Specifically, the positioning frame 13 can be used to fix the connecting rod 3, and the positioning ring 12 can make the device inside the body 1.

[0033] As a further improvement of this utility model, a thermoplastic polyurethane elastomer 18 is fixedly connected to the inner wall of the vent 2, and the inner wall of the thermoplastic polyurethane elastomer 18 is fixed to the positioning ring 12.

[0034] Specifically, the thermoplastic polyurethane elastomer 18 has excellent elasticity and flexibility, can be stretched and return to its original shape, and has better breathability, which helps to allow air to circulate inside the toy.

[0035] As a further improvement of this utility model, the inner liner body 1 consists of a waterproof layer 14 and a protective layer 15 from the outside to the inside, and the waterproof layer 14 and the protective layer 15 are fixed by adhesive.

[0036] Specifically, the adhesive used can increase the filling between the waterproof layer 14 and the protective layer 15, thereby improving the waterproofing capability of the waterproof layer 14 and the protective layer 15.

[0037] As a further improvement of this utility model, the waterproof layer 14 is made of nylon silk material 16, and the protective layer 15 is made of polyvinyl chloride material 17.

[0038] Specifically, the nylon fabric 16 has high strength and toughness, and can withstand greater tension and pressure, making the structure of the inflatable toy more stable. At the same time, together with the polyvinyl chloride 17, it can prevent moisture from entering the toy to a certain extent and protect other materials inside the liner.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] The working principle of this utility model is as follows: During use, a fan is installed at the vent 2 of the inner liner body 1 to inflate the inner liner body 1. As the amount of gas in the inner liner body 1 increases, the inner liner body 1 enlarges. With the intermittent rotation of the fan turbine blades, or different turbine speeds, the rate of increase of the amount of gas in the inner liner body 1 varies, resulting in different air pressures on the limbs. When the air pressure changes, the elastic force of the connecting spring 11 applies force to the connecting block 9, causing the connecting block 9 to slide in the inner wall of the connecting groove 8. In conjunction with the sliding of the connecting shaft 5 in the inner wall of the connecting port 4, the angle between the rocker arm 6 and the connecting rod 3 changes. This change in the angle between the connecting plate 10 and the rocker arm 6, combined with the different forces applied to the inner wall of the limbs of the inner liner body 1 by the rocker head 7, causes the limbs of the inner liner body 1 to swing. Therefore, the limbs of the inner liner body 1 can be extended, improving the aesthetic appeal of the equipment.
