[0002] Launch toys are toys that use paper rockets or foam rocket launch systems to simulate the launch and flight of aerospace rockets. 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.

[0003] For example, the Chinese patent document with publication number CN106164616B discloses a rotary pneumatic launcher for multiple toy rockets, wherein the rocket launch assembly includes a launch base, on which a rotating tube turntable is fixed. The tube turntable supports multiple vertical launch tubes. An air bag is provided. The air bag is connected to the launch base via a flexible hose. In order to use the rocket launch assembly, multiple toy rockets are placed on the vertical launch tubes. When a person steps on the air bag, air is exhausted through the flexible hose. The exhausted air enters any one of the vertical launch tubes in the launch position. The exhausted air then causes the toy rocket to be launched into the air.

[0004] The launch height and distance of the rocket model are determined by the strength of stepping on the airbag, as well as the air pressure formed in the launcher and the rocket model. The pressure of the rocket model and the launcher mainly depends on the air tightness of the rocket model and the launcher. For the technical solutions of the above patent documents, in order to increase the air tightness of the rocket launch, the rocket and the launch tube are usually matched in a tight fit. Therefore, a certain amount of strength and skill are required when putting the rocket on the launch tube. For children, it is relatively difficult to put the rocket on the launch tube because a certain amount of strength is required, and the rocket may be bent. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0031] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0032] In one embodiment of the launch structure of the foot-operated pneumatic toy of the present invention, please refer to Figures 1 to 7. It includes a launch tube 100 and a bazooka 200. The bazooka 200 is used to be sleeved on the launch tube 100. The bottom end of the launch tube 100 is provided with a connector 300 for connecting to an air pump 400. Therefore, after the bazooka 200 is sleeved on the launch tube 100, the air flow is ejected from the launch tube 100 by stepping on the air pump 400, thereby pushing out the bazooka 200. Among them, the bazooka 200 can be made of foam material, so that the bazooka has a certain elasticity, and has a certain strength and hardness. The connector 300 is provided with a positioning seal extending upward; the positioning seal is used to position and seal the bottom end of the bazooka 200. The bazooka 200 is provided with an inner hole 201 for being sleeved on the launch tube 100. The aperture of the inner hole 201 is not less than the outer diameter of the launch tube 100. Therefore, when the rocket launcher 200 is put on the launch tube 100, there is no tight fit phenomenon, so the rocket launcher 200 can be easily put on the launch tube 100, and the problem of the rocket launcher 200 bending can be avoided in the process of putting the rocket launcher 200 on the launch tube 100. Furthermore, the aperture of the inner hole 201 is larger than the outer diameter of the launch tube 100. Therefore, it is more convenient to put the rocket launcher 200 on the launch tube 100.

[0033] An embodiment of a positioning seal for positioning and sealing a rocket launcher 200; specifically, referring to Figures 2 to 5 The positioning seal system connector 300 is provided with a positioning ring 320 extending upward, and the positioning ring 320 and the connector 300 form a positioning cavity 321. The positioning cavity 321 is used to position and seal the lower end of the rocket launcher 200. Specifically, the inner diameter of the positioning ring 320 is not greater than the outer diameter of the bottom end of the rocket launcher 200. Therefore, when the rocket launcher 200 is sleeved on the launch tube 100, the lower end of the rocket launcher 200 can be extended into the positioning cavity 321 to achieve positioning and sealing of the rocket launcher 200. More specifically, the inner diameter of the positioning ring 320 is smaller than the outer diameter of the rocket launcher 200. Therefore, after the rocket launcher 200 is inserted into the positioning cavity 321, it can be tightly connected, which increases the air tightness of the rocket launcher 200 while increasing the resistance to the rocket launcher 200. In turn, the air pressure in the closed structure formed between the rocket launcher 200 and the launch tube 100 can be increased, which can increase the thrust of the rocket launcher 200 when it separates from the launch tube 100, thereby further increasing the launch distance and height.

[0034] Another embodiment of the positioning seal positioning and sealing rocket launcher 200; specifically, refer to Figure 6 and Figure 7The positioning seal is provided on the boss 330 on the connecting member 300, and the launch tube 100 is provided on the boss 330. The outer diameter of the boss 300 is larger than the aperture of the inner hole 201. When the rocket launcher 200 is mounted on the launch tube 100, the lower end of the inner hole 201 is tightly mounted on the boss 330. The boss 330 positions and seals the rocket launcher 200. Further, a step hole 202 is provided at the lower end of the inner hole 201. The aperture of the step hole 202 is larger than the aperture of the inner hole 201 and smaller than the outer diameter of the boss 330.

[0035] Further, refer to Figure 3 and Figure 5 One end of the connecting piece 300 is arranged at the pipe joint 310, and the pipe joint 310 and the connecting piece 300 are also provided with a plug hole penetrating the pipe joint 310, and the launching tube 100 is detachably connected to the plug hole. Therefore, the launching tube 100 can be disassembled from the connecting piece 300.

[0036] Furthermore, a protective member 120 is provided at the end of the launch tube 100. The protective member 120 has a top surface 121. The top surface 121 and the side surface 122 form a circular arc angle 123. The top surface 121 is provided with an air hole 124. In this embodiment, when the rocket launcher 200 is mounted on the launch tube 100, the circular arc angle 123 can cause the end of the launch tube 100 to scrape against the inner wall of the inner hole 201, thereby providing good protection for the inner wall of the inner hole 201.

[0037] Reference Figure 2 The top surface of the protective member 120 is provided with a plurality of air holes 124, and an elastic protective strip 125 is formed between two adjacent air holes 124. Therefore, it is possible to prevent the internal components of the rocket launcher 200 (such as electronic components such as light-emitting lamp beads) from extending into the air holes 124, thereby protecting the internal components.

[0038] Further, refer to Figure 8 The protective member 120 includes a head 125 and a tail 126. The tail 126 and the head 125 form a step. The tail 126 extends into the inner hole of the launch tube 100. The step is limited at the end of the launch tube 100. A plurality of protrusions 127 are also provided on the outer side of the tail 126. Therefore, the connection stability between the protective member 120 and the launch tube 100 is increased.

[0039] Further, the outer diameter of the head 125 is larger than the outer diameter of the launch tube 100, and is not larger than the aperture of the inner hole 201. Therefore, when the rocket launcher 200 is sleeved on the launch tube 100, the contact area is reduced, so that the rocket launcher 200 is sleeved on the launch tube 100 more smoothly.

[0040] 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.
