Description

Technical Field

[0001] The utility model shows a swing structure of a paper model and a paper model, belonging to the technical field of paper models. Background Art

[0002] Paper models, also commonly known as card models, are three-dimensional works of art made of thick paper or card materials. They are made by splicing multiple pre-cut paper parts to create a variety of structural shapes. They are not only a good choice for home decoration, but also a popular project for children's education and entertainment. In particular, three-dimensional paper models are deeply loved by parents and children for their easy operation, safety and educational significance.

[0003] The rotatability of paper models plays a big role in their fun; for example, in animal models, the opening and closing of the mouth can be demonstrated by the swinging of the jaw relative to the head, and the movement of long vertebrates can be demonstrated by the swinging of the spine segments.

[0004] The dynamic structure of paper models usually relies on special connectors, which are equipped with a pair of symmetrical ears designed to be precisely embedded in the waist-shaped holes on both sides of the paper model to achieve a smooth swinging effect; the assembly process starts with the stable installation of the connector, and then the pair of ears are precisely docked to the inside of the pre-cut waist hole, using an inside-out assembly strategy. Although this process ensures the stable operation of the active parts of the model, it also puts higher requirements on the design and assembly skills of the fine structure, increases the complexity and challenge of paper model making, and also makes the splicing of paper models more complicated. Utility Model Content

[0005] The utility model aims to solve the problem that the swing structure of the existing paper model is relatively complicated. To this end, a swing structure of a paper model and a paper model are provided, and the elastic characteristics of the swing part itself are utilized to achieve a simple connection between the swing part and the fixing part.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A swing structure of a paper model comprises a fixed part and a swing part, wherein the fixed part has two relatively fixed hanging ears, the swing part is installed between the two hanging ears, the swing part comprises a sheet-shaped swing body, the swing body has bending parts on opposite sides, the bending parts have a swinging tendency to be flush with the swing body, the bending parts are provided with a plug hole, and the plug hole has an arc-shaped edge, and the hanging ear is inserted into the plug hole to realize the hinge connection between the swing part and the fixed part.

[0008] The beneficial effects of adopting the utility model are:

[0009] The fixing part described in the utility model is the basic supporting part of the overall swinging structure, which is hinged with the swinging part through two hanging ears and provides a stable supporting frame for the installation of the swinging part. The bent part of the swinging part has a socket matching the hanging ear, and the socket has an arc edge so that the hanging ear and the socket cooperate to enable the swinging part to swing, so that the hinge connection between the swinging part and the fixing part can be achieved without using other additional fixing elements, making the assembly of the swinging part and the fixing part simpler and more convenient; in addition, the swinging part itself has a certain thickness and toughness, and the bent part is formed by bending the side of the swinging body. Therefore, the bent part has a swinging tendency to remain flush with the swinging body under the action of the elasticity of the swinging part itself, that is, after the swinging part is positioned between the two hanging ears through the bent part, the swinging part has the outer side of the hanging ear The swinging movement trend ensures that the hook can pass through the socket, so that the hook can maintain a stable connection with the socket of the bending part, reducing the possibility of the hook detaching from the socket, and making the connection between the fixing part and the swinging part more stable and reliable. The utility model utilizes the elastic characteristics of the swinging part itself to enhance the connection stability between the swinging part and the fixing part. There is no need to use glue or additional fixing elements to reinforce the connection between the swinging part and the fixing part, making its overall structure simpler, simplifying the assembly steps, improving assembly efficiency, and ensuring the stability and durability of the swinging structure during multiple swinging processes. It is very suitable for paper models and other card model applications that require frequent actions or display of dynamic effects, such as educational models, toys or decorations, etc., greatly enriching the design space and user experience of such products.

[0010] Preferably, the jack is circular. By adopting the above technical solution, the swing amplitude of the swinging member can be increased, so that the paper model has a more obvious display effect, which helps to improve the user experience.

[0011] Preferably, the two bent portions are bent in the same direction relative to the swing body and are located on the same side of the swing body; or, the two bent portions are bent in different directions relative to the swing body so that the two bent portions are located on both sides of the swing body. With the above technical solution, the two bent portions are bent in the same direction, which can make the force on the swinging member more balanced and make the swinging member swing more stable and smooth.

[0012] Preferably, the fixing member includes a fixing body and two pins extending from the fixing body, the hook is located on the inner side of the two pins, the two bent portions are bent in the same direction relative to the swinging body, and there is an escape space between the hook and the fixing body for evading the bent portions. With the above technical solution, the pin can limit the bent portion so that the bent portion and the pin are in contact, thereby enhancing the matching stability of the bent portion and the pin, helping to reduce the shaking amplitude of the swinging body in the non-swinging direction, and improving the connection tightness between the swinging member and the fixing member.

[0013] Preferably, the swing body is located between two pins.

[0014] Preferably, the pin extends to form a step portion on the side of the hook away from the fixed body, and the two sides of the swing body are positioned between the two steps. With the above technical solution, the step portion can increase the thickness of the part where the hook is located, thereby strengthening the strength of the pin, improving the pin's anti-deformation ability, helping to reduce the possibility of deformation of the pin due to multiple swings, and significantly extending the service life of the swing structure.

[0015] Preferably, the bending portion has a maximum bending width at the insertion hole, and the bending width of the bending portion gradually decreases toward the end away from the insertion hole. With the above technical solution, as the bending width decreases, the rigidity of the swing member in this area is enhanced, and it can withstand greater torsional stress. The portion with a smaller bending width can more effectively resist the load caused by bending, and the bending portion has a greater swinging tendency at the insertion hole, ensuring that the bending portion can be firmly connected between the two hanging ears, and can maintain good positioning and stability even in continuous swinging motion.

[0016] Preferably, the bending width of the end of the bending portion away from the insertion hole is smaller than the thickness of the swing body.

[0017] The utility model also shows a paper model, comprising a head with a fixing part and a lower jaw with a swinging part, wherein the fixing part and the swinging part form a swinging structure as described in any one of the above items.

[0018] Other features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiment 1:

[0032] like Figures 1 to 4As shown, this embodiment shows a swing structure of a paper model, including a fixed part 1 and a swing part 2, the fixed part 1 has two relatively fixed ears 13, the swing part 2 is installed between the two ears 13, the swing part 2 includes a sheet-like swing body 21, the swing body 21 has a bending portion 22 on opposite sides, the bending portion 22 has a swinging tendency to remain flush with the swing body 21, the bending portion 22 is provided with a plug hole 221, and the plug hole 221 has an arc edge, the ear 13 is inserted into the plug hole 221 to realize the hinge connection between the swing part 2 and the fixed part 1.

[0033] The fixing member 1 described in this embodiment is the basic supporting part of the overall swinging structure, which is hinged with the swinging member 2 through two hanging ears 13 and provides a stable supporting frame for the installation of the swinging member 2. The bent portion 22 of the swinging member 2 has a socket 221 matching the hanging ear 13, and the socket 221 has an arc edge so that the hanging ear 13 cooperates with the socket 221 to enable the swinging member 2 to swing, so that the hinge connection between the swinging member 2 and the fixing member 1 can be achieved without using other additional fixing elements, making the assembly of the swinging member 2 and the fixing member 1 simpler and more convenient; in addition, the swinging member 2 itself has a certain thickness and toughness, and the bent portion 22 is formed by bending the side of the swinging body 21. Therefore, the bent portion 22 has a swinging tendency to remain flush with the swinging body 21 under the action of the elasticity of the swinging member 2 itself, that is, after the swinging member 2 is positioned between the two hanging ears 13 through the bent portion 22, it swings Part 2 has a movement tendency of swinging on the outside of the ear 13, ensuring that the ear 13 can pass through the socket 221, so that the ear 13 can maintain a stable connection with the socket 221 of the bending part 22, reducing the possibility of the ear 13 being separated from the socket 221, and making the connection between the fixing part 1 and the swinging part 2 more stable and reliable. This embodiment uses the elastic characteristics of the swinging part 2 itself to enhance the connection stability between the swinging part 2 and the fixing part 1, and does not need to use glue or additional fixing elements to reinforce the connection between the swinging part 2 and the fixing part 1, making its overall structure simpler, simplifying the assembly steps, improving assembly efficiency, and ensuring the stability and durability of the swinging structure during multiple swings. It is very suitable for paper models and other card model applications that require frequent actions or display of dynamic effects, such as educational models, toys or decorations, etc., greatly enriching the design space and user experience of such products.

[0034] like Figure 4As shown, the fixing member 1 in this embodiment includes a fixing body 11 and two pins 12 extending from the fixing body 11, the ear 13 is located on the inner side of the two pins 12, the two bending portions 22 are bent in the same direction relative to the swinging body 21, and there is an avoidance space 121 between the ear 13 and the fixing body 11 for avoiding the bending portion 22, the pin 12 can limit the bending portion 22 so that the bending portion 22 is in abutment with the pin 12, thereby enhancing the matching stability of the bending portion 22 and the pin 12, helping to reduce the shaking amplitude of the swinging body 21 in the non-swinging direction, and improving the connection tightness between the swinging member 2 and the fixing member 1.

[0035] In addition, in order to increase the strength of the position where the hook 13 is located, the pin 12 in this embodiment extends on the side of the hook 13 away from the fixed body 11 to form a step portion 122, and the two sides of the swing body 21 are positioned between the two step portions 122. The step portion 122 can increase the thickness of the position where the hook 13 is located, thereby strengthening the strength of the pin 12, improving the deformation resistance of the pin 12, and helping to reduce the possibility of deformation of the pin 12 due to multiple swings, which can significantly extend the service life of the swing structure.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the two bending portions 22 are bent in the same direction relative to the swing body 21 and are located on the same side of the swing body 21. When the swing member 2 is assembled with the fixing member 1, the bending portions 22 rebound to both sides of the swing member 2 under the action of their own elasticity, thereby abutting against the pins 12 located in the avoidance space 121. When the two bending portions 22 are bent in the same direction, the force on the swing member 2 can be more balanced, and the swing of the swing member 2 can be more stable and smooth. Of course, it can be understood that in other embodiments, the two bending portions 22 are bent in different directions relative to the swing body 21 so that the two bending portions 22 are located on both sides of the swing body 21, that is, one of the bending portions 22 is bent toward the upper side of the swing body 21 and abuts against the pins 12 located in the avoidance space 121 after assembly, and the other bending portion 22 is bent toward the lower side of the swing body 21 and abuts against the step portion 122 on the lower side of the hanging ear 13 after assembly.

[0037] In addition, in this embodiment, an arc-shaped edge is formed on the upper end of the socket 221 to facilitate guiding the socket 221 and the ear 13 to swing relative to each other. It can be understood that in other embodiments, the socket 221 as a whole can be a circular structure. The use of a circular structure can increase the swing amplitude of the swinging member 2, so that the paper model has a more obvious display effect, which helps to improve the user experience.

[0038] like Figure 2 and Figure 3As shown, the bending portion 22 described in this embodiment has a maximum bending width at the insertion hole 221, and the bending width of the bending portion 22 gradually decreases toward the end away from the insertion hole 221, and the bending width of the end of the bending portion 22 away from the insertion hole 221 is less than the thickness of the swing body 21. As the bending width decreases, the rigidity of the swing member 2 in this area is enhanced, and it can withstand greater torsional stress. The portion with a smaller bending width can more effectively resist the load generated by bending, and make the bending portion 22 have a greater swinging tendency at the insertion hole 221, ensuring that the bending portion 22 can be firmly connected between the two hanging ears 13, and can maintain good positioning and stability even in continuous swinging motion. It should be noted that the bending portion 22 described in this embodiment is obtained by bending the side of the sheet-like swing body 21, so the bending width described in this embodiment is the width of the bent side.

[0039] In addition, this gradient design from wide to narrow helps to optimize the distribution of materials, which not only ensures the strength of key stress-bearing areas, but also avoids unnecessary material accumulation, so that the entire swing structure can maintain high strength while being lightweight. This is extremely beneficial for improving the flexibility of paper models and reducing transportation and production costs.

[0040] Embodiment 2:

[0041] like Figure 5 and Figure 6 As shown, this embodiment shows a paper model, including a head 31 with a fixing part 1, a lower jaw 33 with a swinging part 2, and a torso 32 fixedly connected to the head 31, wherein the fixing part 1 and the swinging part 2 form a swinging structure as described in the first embodiment.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
