Description

Technical Field

[0001] The utility model belongs to the technical field of flying toy products, and in particular relates to a toy rocket structure. Background Art

[0002] The toy rocket structure is a toy that simulates the launch and flight of an aerospace rocket by using a paper rocket or a foam rocket launch system. The toy rocket structure is widely favored by the market for its fun and educational value.

[0003] The Chinese patent document with publication number CN106164616A discloses a rotary pneumatic launcher for multiple toy rocket structure bombs, including: a launch base, which includes multiple launch tubes and a launch position; multiple toy rocket structure bombs, which slide onto the multiple launch tubes; a manually operated air source, which is combined with the launch base for generating air pulses; and a rotating mechanism, which is used to move the multiple launch tubes to the launch position in sequence, wherein the rotating mechanism is activated by the air pulse. When the toy rocket structure bomb is launched, the toy rocket structure bomb needs to be put on the launch tube, and the manually operated air source (air bag) provides a pulse air source to the launch tube to push the toy rocket structure bomb out of the launch tube. In order to increase the stability of the toy rocket structure bomb in flight, it is necessary to set three groups of side wings at the tail of the rocket. The material of the toy rocket structure bomb and the side wings is usually foam material, and the side wings are generally bonded to the outside of the rocket body by gluing.

[0004] According to the specification of the above patent document Figure 1 and 2 From the pictures released, it can be seen that the wing is approximately in the shape of a right triangle, and the long right-angled side is connected to the rocket body. Therefore, the angle formed by the two right-angled sides forms the end point of the wing connection. When picking up a rocket, the user will generally grab the wing position, and grab the short side position. When picking it up, the force points of the wing will be concentrated at the end of the right-angled side of the wing; therefore, the end position where the wing is connected to the rocket will be susceptible to the problem of cracking due to pulling force, thereby shortening its service life. Utility Model Content

[0005] The utility model aims to provide a toy rocket structure to solve the problem that the existing rocket toys are easily torn and separated, resulting in a short service life.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides a toy rocket structure, including a rocket body and side wings bonded to the outside of the rocket body, the side wings having a tail end face, an extension portion extending from the bottom end of the tail end face, the bottom of the extension portion and the bottom of the side wing forming a fitting surface, which is connected to the rocket body.

[0007] Furthermore, the tail end surface and the extension portion form an angle smaller than 90°.

[0008] Furthermore, a connecting section is formed between the tail end surface and the extension portion, and the connecting section is a straight line segment, and the connecting section is connected to the extension portion and the tail end surface in an arc transition.

[0009] Furthermore, a protective position is formed between the free end of the extension portion and the end of the rocket body, so that the free end of the extension portion is away from the end of the rocket body.

[0010] Furthermore, the rocket body and the side wings are both made of foam.

[0011] Furthermore, the rocket body and the side wings can be connected by hot melting or gluing, and the side wings are evenly distributed on the outside of the rocket body.

[0012] Furthermore, a groove is hot-melt molded on the outer side of the rocket body, and the fitting surface is hot-melt bonded in the groove.

[0013] Furthermore, the extension portion is located in the groove, and the outer surface of the extension portion is not higher than the outer surface of the rocket body.

[0014] The above one or more technical solutions in the toy rocket structure provided by the embodiment of the utility model have at least the following technical effects:

[0015] In the toy rocket structure, since the bottom end of the tail end surface of the wing is extended with an extension part, the bottom of the extension part and the bottom of the wing form a fitting surface connected to the rocket body. Therefore, when the wing is grasped, the pulling force on the wing is not in the same straight line as the end point where the wing is connected to the rocket body; so when the wing is grasped, the force at the connection between the wing and the rocket body will be distributed on the entire fitting surface; therefore, the connection strength between the wing and the rocket body can be increased by setting the extension part, avoiding the force at the end position of the fitting surface. This effectively avoids the problem of the wing cracking from the end of the fitting surface, and can increase the service life of the rocket. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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.

[0026] 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.

[0027] In one embodiment of the toy rocket structure of the utility model, please refer to Figure 1 and Figure 2 . Specifically, the toy rocket structure includes a rocket body 10 and a wing 20 bonded to the outside of the rocket body 10, the wing 20 has a tail end face 21, and an extension portion 22 extends from the bottom end of the tail end face 21, and the bottom of the extension portion 22 forms a fitting surface 23 with the bottom of the wing 20, and the fitting surface is connected to the rocket body 10. Therefore, in the toy rocket structure of this embodiment, when the rocket is picked up and the wing 20 is grabbed, the pulling force on the wing 20 is not in the same straight line as the end point where the wing 20 is connected to the rocket body 10, so that the force at the connection between the wing 20 and the rocket body 10 will be distributed on the entire fitting surface 23; therefore, the connection strength between the wing 20 and the rocket body 10 can be increased by setting the extension portion 22, avoiding the force at the end position of the fitting surface 23. Thereby, the problem of the wing 20 cracking from the end of the fitting surface 23 can be effectively avoided, and the service life of the rocket can be improved.

[0028] Furthermore, the tail end face 21 and the extension part 22 form an angle less than 90°, and a connecting section 25 is formed between the tail end face 21 and the extension part 22. The connecting section 25 is a straight line segment, and the connecting section 25 is transitionally connected to the extension part 22 and the tail end face 21 through an arc 24. Specifically, when grabbing the wing 20, the connecting end 25 is connected to the two arcs 24 of the extension part 22 and the tail end face 21, so that the pulling force of the wing 20 can be dispersed in the transition part of the connecting end and the two arcs 24 of the extension part 22 and the tail end face 21, avoiding the problem of stress concentration at one point and causing cracking at that position, thereby enhancing the connection strength between the wing 20 and the rocket body 10.

[0029] Furthermore, a protective position 12 is formed between the free end of the extension 22 and the end of the rocket body 10, so that the free end of the extension 22 is away from the end of the rocket body 10. Therefore, the free end of the extension 22 does not overlap with the end of the rocket body 10, effectively preventing the end of the extension from being scratched, dusted, etc., and avoiding the problem of cracking from the end of the extension, thereby improving the service life of the rocket.

[0030] Furthermore, the rocket body 10 and the side wings 20 are both made of foam, and the two can be connected by hot melting. When the outer side of the rocket body 10 is formed with a groove 13 by hot melting, the fitting surface 23 of the side wings 20 and the extension 22 can be hot melt bonded in the groove 13, and the outer surface of the extension 22 is not higher than the outer surface of the rocket body 10. Specifically, when the fitting surface 23 is hot melt bonded to the hot melt groove 13 on the outer side of the rocket body 10, and the outer surface of the extension 22 is not higher than the outer surface of the rocket body 10, the extension is prevented from being scratched, which may cause the extension to crack due to the scratching force.

[0031] 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.
