[0034] Example 1: Figure 1-5 As shown, a quick-install joint for a model toy includes a limb segment 1 and a connecting segment 2. One end of the limb segment 1 is used to connect with the toy limb, and the other end of the limb segment 1 is snap-fitted and assembled with the connecting segment 2. The connecting segment 2 is used to snap-fit ​​and assemble the limb segment 1 with the toy torso 3. The limb segment 1 is provided with a snap-fitting groove 101, and the connecting segment 2 is provided with a snap-fitting block 201 for snapping with the snap-fitting groove 101. When the limb segment 1 and the connecting segment 2 are assembled, the snap-fitting block 201 is snap-fitted in the snap-fitting groove 101. By snap-fitting and assembling the limb segment 1 with the connecting piece, the toy limb and the toy torso 3 are snap-fitted and assembled, replacing the method of connecting the toy limb and the toy torso 3 with screws in the prior art. In terms of production and assembly, the assembler can complete the assembly of the model toy by snap-fitting the toy limb and the toy torso 3, reducing the time and effort. Low assembly difficulty, simplified assembly steps, improved assembly efficiency, and increased production of model toys. In terms of children's use, since the toy limbs and the toy torso 3 are assembled by snap-fitting, the impact of loose screws or rusted screws on children during use is reduced, and the connecting section 2 is located inside the toy torso 3, and the snap-fit ​​position of the limb section 1 and the connecting section 2 is located inside the toy torso 3, that is, the snap-fit ​​block 201 and the snap-fit ​​groove 101 are located inside the torso 3, so that once the toy limbs and the toy torso 3 are snap-fitted and assembled, it is difficult to disassemble the toy limbs from the outer surface of the toy torso 3, thereby reducing the possibility that the model toy cannot be assembled after being disassembled by children when playing, and this design method ensures that the outer surface of the model toy has no exposed connecting parts, and can be designed as a smooth surface to avoid harm to children when playing.

[0035] Among them, the connecting section 2 is cylindrical, the outer wall of the limb section 1 is adapted to the inner wall of the connecting section 2, and the limb section 1 is assembled in the connecting section 2. By inserting the limb section 1 into the connecting section 2, the contact area between the limb section 1 and the connecting section 2 is increased, thereby improving the stability of the assembly of the limb section 1 and the connecting section 2, improving the firmness of the connection between the limb section 1 and the connecting section 2, reducing the risk of the toy limbs and the toy torso 3 falling off during the use of the model toy, and improving the firmness of the assembly of the toy limbs and the toy torso 3.

[0036] In order to improve the stability of the connection between the connecting section 2 and the limb section 1, the connecting block 201 has a protruding flange portion 2011, and the flange portion 2011 is protruded from the connecting block 201 toward the connecting groove 101. When the limb section 1 and the connecting section 2 are connected, the flange portion 2011 is connected to the connecting groove 101, thereby playing an anti-detachment role, improving the stability of the connection assembly between the limb section 1 and the connecting section 2, reducing the risk of detachment between the toy limb and the toy torso 3 during use, and improving the stability of the assembly of the toy limb and the toy torso 3.

[0037] In order to facilitate the snap-fitting and assembly of the flange portion 2011 into the snap-fitting groove 101, the flange portion 2011 is provided with a flat area 2012 and a guide area 2013. The flat area 2012 is located on the top wall of the flange portion 2011 and is arranged parallel to the inner surface of the snap-fitting block 201 facing the connecting section 2. The guide area 2013 is gradually inclined from the inner surface of the connecting section 2 toward the flat area 2012. When the limb segment 1 is inserted into the connecting section 2, the guide area 2013 is provided to guide the assembly of the limb segment 1, making it easier to snap the flange portion 2011 into the snap-fitting groove 101, thereby improving the assembly efficiency of the limb segment 1 and the connecting section 2. At the same time, the flat area 2012 is provided to prevent separation, thereby avoiding the possibility that the limb segment 1 slides along the guide area 2013 after the connectable block is assembled with the snap-fitting groove 101, which makes it possible for the pillow body segment to separate from the connecting section 2, thereby improving the stability of the assembly of the toy limb and the toy torso 3.

[0038] In terms of the specific setting of the inclination angle of the guide area 2013, the angle between the guide area 2013 and the inner surface of the clamping block 201 facing the connecting section 2 is slightly 155° to 165°, preferably 161°.

[0039] Furthermore, in order to facilitate the snap-fit ​​assembly of the snap-fit ​​block 201 and the snap-fit ​​groove 101, the snap-fit ​​block 201 is arranged in a square shape, and the connecting section 2 is provided with a U-shaped hole 202, which is arranged to pass through any three sides of the snap-fit ​​block 201, and the flange portion 2011 is arranged at one end of the snap-fit ​​block 201 near the bottom wall of the U-shaped hole 202.

[0040] Among them, the flange portion 2011 is set in a square shape, and the flange portion 2011 corresponding to the clamping groove 101 is also set in a square shape. The notch of the U-shaped hole 202 is set toward the limb segment 1. By providing the U-shaped hole 202, the clamping block 201 has an elastic deformation space. When the limb segment 1 and the connecting segment 2 are clamped, the flange portion 2011 abuts against the top wall of the limb segment 1, and the force is transmitted to the clamping block 201. The clamping block 201 is elastically deformed under the force. When the clamping groove 101 is located below the flange portion 2011, the force of the elastic deformation of the clamping block 201 pushes the flange portion 2011 toward the clamping block 201, so that the flange portion 2011 is clamped in the clamping groove 101, completing the clamping assembly of the limb segment 1 and the connecting segment 2, reducing the difficulty of the clamping assembly of the limb segment 1 and the connecting segment 2, and improving the stability of the assembly of the limb segment 1 and the connecting segment 2.

[0041] In order to further improve the stability of the assembly between the limb segment 1 and the connecting segment 2, thereby reducing the risk of the toy limbs being separated from the toy torso 3 during use of the model toy, the limb segment 1 is provided with two groups of snap-in blocks 201, and the two groups of snap-in blocks 201 are respectively provided on the upper and lower sides of the limb segment 1, and the connecting segment 2 is provided with two groups of snap-in grooves 101 corresponding to the snap-in blocks 201. By providing two groups of snap-in blocks 201 and snap-in grooves 101, the contact area of ​​the snap-in assembly between the limb segment 1 and the connecting segment 2 is increased, thereby improving the stability between the limb segment 1 and the connecting segment 2, and reducing the possibility of the limb falling off during use. Secondly, the two connection points disperse the force on the toy during use, improve durability, and extend the overall service life of the toy.

[0042] Furthermore, in order to improve the stability of the assembly between the limb segment 1 and the connecting segment 2, the limb segment 1 is provided with an annular groove 103 for assembly with the connecting segment 2. When the limb segment 1 is assembled with the connecting segment 2, one end portion of the connecting segment 2 is located in the annular groove 103. The annular groove 103 provides precise positioning, making the assembly process more accurate, reducing assembly errors, improving assembly accuracy, and improving the stability of the assembly between the limb segment 1 and the connecting segment 2. Secondly, the annular groove 103 can better disperse the force, reduce stress concentration at the connection, thereby increasing the strength of the connection, and helping to prevent the connecting segment 2 from loosening after long-term use.

[0043] In order to increase the contact area between the connecting section 2 and the bottom wall of the annular groove 103, the bottom wall of the annular groove 103 is inclined, and an inclined portion is provided at one end where the connecting section 2 and the limb section 1 are assembled. The inclined portion is adapted to the bottom wall of the annular groove 103, effectively increasing the contact area between the connecting section 2 and the bottom wall of the annular groove 103 and improving the stability of the connection. The larger contact area helps to disperse the force, reduce local stress concentration, increase the friction between the limb section 1 and the connecting section 2, and make the connection more secure and less likely to fall off. It is worth mentioning that the bottom wall of the annular groove 103 refers to the side of the limb section 1 facing the connecting section 2, that is, the side where the limb section 1 contacts the end wall of the connecting section 2 when the limb section 1 and the connecting section 2 are assembled.

[0044] Example 2: Figure 1-9 As shown, a toy of the Baobao dragon includes a quick-release joint for a model toy in Example 1, and further includes a torso 3 and two groups of leg limbs 4. The torso 3 is provided with an insertion hole 301, and the connecting section 2 is snap-fitted and assembled on the inner wall of the insertion hole 301. Two groups of limb sections 1 are provided and are respectively connected to the two groups of leg limbs 4. The two groups of limb sections 1 are snap-fitted and assembled on the two ends of the connecting section 2. By providing a quick-release joint, when assembling the Baobao dragon toy, the connecting section 2 is snap-fitted and assembled with the insertion hole 301 of the torso 3 to complete the assembly of the connecting section 2 and the torso 3. Then, the connecting section 2 connected with the leg limbs 4 is snap-fitted and assembled with the connecting section 2, thereby completing the assembly of the two groups of leg limbs 4, improving the assembly effect of the Baobao dragon toy, and simplifying the Baobao dragon toy. With regard to the assembly process of the dragon-shaped toy, since the leg limbs 4 and the torso 3 are assembled by snap-fitting, the impact of loose screws or rusted screws on children during use is reduced, and the connecting section 2 is located inside the torso 3, and the snap-fitting position of the limb section 1 and the connecting section 2 is located inside the toy torso 3, that is, the snap-fitting block 201 and the snap-fitting groove 101 are located inside the torso 3, so that once the toy limbs and the torso 3 are snap-fitted and assembled, it is difficult to disassemble the leg limbs 4 from the outer surface of the dragon-shaped toy, thereby reducing the possibility that the dragon-shaped toy cannot be assembled after being disassembled by children when playing, and this design method ensures that the outer surface of the dragon-shaped toy has no exposed connecting parts and can be designed as a smooth surface to avoid injury to children when playing.

[0045] It is worth mentioning that since both ends of the connecting section 2 are clamped with limb sections 1, in order to reduce the difficulty of opening and processing the U-shaped holes 202 of the connecting section 2, the U-shaped holes 202 corresponding to the two groups of limb sections 1 are connected and arranged.

[0046] In terms of the specific structure of the snap-fit ​​assembly of the connecting piece and the torso 3, two groups of snap-fit ​​blocks 201 are respectively arranged on the top wall of the connecting section 2 and the bottom wall of the connecting section 2, the side wall of the connecting section 2 is provided with a protruding snap-fit ​​block 203, and the inner side wall of the insertion groove is provided with an assembly portion 302. When the connecting piece is snap-fitted and assembled with the torso 3, the snap-fit ​​block 203 abuts against the assembly portion 302, thereby completing the snap-fitting of the connecting section 2 and the torso 3.

[0047] In order to improve the stability of the assembly of the connecting section 2 and the body, the connecting section 2 is tapered. The inner wall of the insertion hole 301 is adapted to the connecting section 2 and is tapered. The connecting section 2 gradually shrinks from the end provided with the clamping block 203 toward the other end of the connecting section 2. The outer wall of the connecting section 2 has a protruding limiting portion 204. The limiting portion 204 is provided at the end away from the clamping block 201. The insertion hole 301 is provided with a limiting groove 303 for assembling with the limiting portion 204. When the connecting section 2 is assembled with the torso 3, it is inserted from the end with the larger opening of the plug-in hole. Of course, the end of the outer wall of the connecting piece is inserted into the plug-in hole first. When the limiting part 204 abuts against the limiting groove 303, the clamping part and the assembly part 302 are clamped and assembled, thereby completing the assembly of the connecting section 2 and the torso 3. The assembly position of the clamping part and the assembly part 302 is located in the torso, which reduces the possibility of the connecting section 2 being unstuck or disassembled during use, and improves the stability of the assembly of the leg limb 4 and the torso.

[0048] Of course, in order to reduce the assembly process of the leg limb 4 and the limb segment 1, the leg limb 4 and the limb segment 1 are designed to be integrally formed, and the connecting segment 2 and the torso 3 are designed to be integrally formed.

[0049] This embodiment also includes a head 5, a linkage box 501, two sets of arm limbs 6, a rotating shaft 601, and a fork 602. The two sets of arm limbs 6 are respectively connected to the two ends of the axis of the rotating shaft 601. The fork 602 is connected to the outer ring wall of the rotating shaft 601 and is located in the torso 3. The rotating shaft 601 is rotatably assembled with the torso 3. The head 5 is assembled with the linkage box 501. The linkage box 501 is assembled on the torso 3 and is used to move the head 5 toward the torso 3. The fork 602 is inserted into the reset block 5011 of the linkage box 501 and is used to reset the linkage box 501.

[0050] In order to limit the rotational travel of the two groups of arm limbs 6, the fork 602 has a protruding blocking portion 6021, which is arranged perpendicular to the fork 602. When the arm limbs 6 are rotated to reset the linkage box 501, the blocking portion 6021 abuts against the inner wall of the torso 3.

[0051] It is worth mentioning that the linkage box 501 is a prior art. For its specific structure, reference may be made to the Chinese utility model patent with announcement number CN210473053U. The linkage box 501 in this embodiment corresponds to the pressing component in the prior art.

[0052] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
