Launch toys are widely favored by the market for their fun and educational value. In related technical means, a launch stand is fixed on the toy base, and the launch stand is connected to a driving air bag. The rocket model is installed on the launch stand, and the operator creates an air pulse by compressing the driving air bag, and uses the air pulse to impact the rocket model to achieve the purpose of launching the rocket model.

[0027] In the embodiment 1 of the foldable support structure of the utility model, please refer to Figures 1 to 3 . Specifically, the foldable support structure includes a connecting base 100 and a plurality of supporting legs 200. The supporting legs 200 have a supporting end 201 and a connecting end 202. The connecting base 100 includes a bottom shell 110 and a top shell 120. A fixing member 130 is provided between the bottom shell 110 and the top shell 120, so that the bottom shell 110 and the top shell 120 are fixedly connected and an installation cavity 101 is formed. A connecting member 140 is provided in the installation cavity 101, and a connecting hole 203 is provided at the connecting end 202 of the supporting leg 200, and the connecting hole 203 is rotatably mounted on the connecting member 140. A limiting card slot 102 is provided on the top side or the bottom side of the installation cavity 101, and an opening slot 204 is provided at the connecting end 202. The opening slot 204 forms an elastic arm 210 at the connecting end. After the supporting leg 200 is unfolded, the elastic arm 210 is inserted into the corresponding limiting card slot 102.

[0028] In the above embodiment, when the support leg 200 is unfolded and supported on the ground, the corresponding support leg 200 can be rotated, and when the elastic arm 210 is rotated to the corresponding position of the limit slot 102, the elastic arm 210 is inserted into the limit slot 210, and the support leg 200 is limited to prevent rotation, so that when supported on the ground, the stability of the support can be increased. When it is necessary to store, the elastic arm 210 is pressed to disengage the elastic arm 210 from the limit slot 102, and then the support leg 200 can be rotated, so that the support leg 200 can be folded for storage and packaging.

[0029] Further, refer to Figure 3 In order to increase the stability of the elastic arm 210 , a through hole 211 is provided at the free end of the elastic arm 210 , and the through hole is sleeved on the connecting member 140 , so that the connecting member 140 limits the free end of the elastic arm 210 .

[0030] Further, refer to Figure 1 The connecting base 100 is connected to three groups of supporting legs 200 , wherein one supporting leg 200 is fixedly connected to the connecting base 100 , and two adjacent supporting legs 200 are rotatably connected to the connecting base 100 .

[0031] Further, refer to Figure 1 The three groups of support legs 200 have the same structure, so the production cost can be reduced. In the specific embodiment where the support legs 200 are fixedly connected to the installation cavity 101, the top side and / or the bottom side of the installation cavity 101 are further provided with a limiting cavity 103, and the support legs 200 fixedly connected to the connection seat 100 are limited in the limiting cavity 103, so that the support legs 200 can be prevented from rotating and are fixedly connected.

[0032] Further, refer to Figure 2 The top wall of the installation cavity 101 is provided with a limiting portion 104 extending downward, and the limiting portion 104 and the side of the fixing member 130 form a limiting slot 102.

[0033] Further, refer to Figure 2 A guide slope 105 is provided on the side of the position-limiting portion 104 away from the fixing member 130. When the support foot 200 is limited in the position-limiting slot 101, the support foot 200 is rotated, and the elastic arm 210 is compressed along the guide slope 105, and manual pressing of the elastic arm 210 is ineffective, and the operation is simple. Moreover, when the elastic arm 210 is not in contact with the position-limiting portion 104, the elastic arm 210 can be prevented from being compressed, and the elastic arm 210 can be prevented from being fatigued and broken.

[0034] Further, refer to Figure 2 The bottom shell 110 extends upwardly to a sleeve, and the top shell 120 extends downwardly to have a support column, which extends into the sleeve to form a connecting piece 140. The locking screw extends from the bottom side of the bottom shell 110 into the sleeve and is connected to the support column; the connecting hole 203 of the connecting end 202 is sleeved on the sleeve.

[0035] Embodiment 2,

[0036] Please refer to Figure 4 and Figure 5 The difference between this embodiment and the above embodiment is that the extension member forming the limit slot 102 is an elastic member 150. Specifically, an arched elastic member 150 is provided on the top wall of the installation cavity 101, and the limit slot 102 is formed by the elastic member 150 and the fixing member 130. The limit member 220 of the connecting end 202 is a protruding portion protruding upward. Therefore, when the supporting foot 200 is rotated, the limit member 220 squeezes the elastic member 150, so that the limit member 220 is inserted into the limit slot 102 along the elastic member 150.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
