Description

Technical Field

[0001] The present invention relates to the technical field of toys, and in particular to a joint structure and a toy doll. Background Art

[0002] At present, existing toys include a hand member, a leg member, and a torso body formed by mating and installing a face shell and a bottom shell. The hand member and the leg member are both provided with joint components for connecting to the torso body. During actual assembly, it is necessary to first disassemble and separate the face shell and the bottom shell, then fixedly install the joint components of the hand member and the leg member to the face shell and / or the bottom shell, and finally mate and install the face shell and the bottom shell to fix the joint parts of the hand member and the leg member. However, since the existing toy assembly is generally carried out manually, this joint connection method of first disassembling and then assembling has cumbersome assembly steps, low assembly efficiency, and also increases the labor intensity of the assembly personnel. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a joint structure and a toy doll with convenient assembly and high assembly efficiency.

[0004] The present invention also provides a joint structure, including a first joint body, a second joint body, and a first connection assembly for connecting the first joint body and the second joint body. The first connection assembly includes a mounting hole position formed on the first joint body, a mounting member provided on the second joint body and used for snap-fitting with the mounting hole position, and a first limiting member for limiting the snap-fitting position of the mounting member when the mounting member is snap-fitted with the mounting hole position.

[0005] Preferably, the mounting hole position includes a snap-fit hole for snap-fitting with the mounting member and a mounting hole communicating with the snap-fit hole; when the mounting member enters the snap-fit hole from the mounting hole, the first limiting member is disposed in the mounting hole to limit the snap-fitting position of the mounting member.

[0006] Preferably, the mounting member includes a snap-fit shaft and a snap-fit limiting portion. One side of the snap-fit shaft away from the second joint body is fixedly connected to the snap-fit limiting portion, and one side of the snap-fit shaft close to the second joint body is rotatably connected to the second joint body; when the mounting member is snap-fitted with the mounting hole position, the snap-fit shaft passes through the snap-fit hole.

[0007] Preferably, a first guiding portion for facilitating its entry into the mounting hole is provided on one side of the snap-fit limiting portion away from the second joint body.

[0008] Preferably, the first limiting member includes an elastic arm, a fixing portion and a limiting blocking portion respectively provided at both ends of the elastic arm. The limiting blocking portion is disposed in the mounting hole, and the first joint body is provided with a fixing column for mounting the fixing portion.

[0009] Preferably, the fixing part is fixedly connected to the fixing column; or the fixing part is rotatably connected to the fixing column, and the first joint body is provided with a stroke limiting part for limiting the rotatable stroke of the fixing part.

[0010] Preferably, a second guiding part for facilitating the installation part to enter the clamping hole from the installation hole is provided on one side of the limiting blocking part close to the second joint body.

[0011] Meanwhile, the present invention also provides a toy doll, including a torso body, a hand member and a leg member. The torso body and the leg member are connected by the above joint structure. The first joint body is detachably installed below the torso body, and the leg member is connected to the second joint body.

[0012] Preferably, the hand member is connected to the torso body through a second connecting assembly. The second connecting assembly includes a plug shaft rotatably connected to the hand member, a plug hole opened in the torso body and in plug-in fit with the plug shaft, and a second limiting member provided on the plug shaft for limiting the position of the plug shaft.

[0013] Preferably, the second limiting member includes a guiding plug part provided on the side of the plug shaft away from the hand member and a plug limiting part provided on the side of the plug shaft close to the hand member. An insertion limiting cavity is formed between the guiding plug part and the plug limiting part. An elastic limiting part is provided at the inner end of the plug hole. When the plug shaft is in plug-in fit with the plug hole, the elastic limiting part and the limiting cavity are used in cooperation to limit the plugging position of the plug shaft.

[0014] The beneficial effects of the present invention are as follows: The above toy body includes a joint structure. The characteristics of this joint structure are as follows: During assembly, the installation part is clamped and installed onto the installation hole position, and the clamping position of the installation part is limited by the first limiting member. In this state, the installation part cannot be directly disassembled from the installation hole position, so as to ensure the firmness of the clamping installation of the installation part and the installation hole position, enabling the first connecting assembly to be used in a high-strength environment (such as vigorously shaking, pulling the first joint body and / or the second joint body, etc.). In this way, the second joint body is installed onto the first joint body by the first connecting assembly in a clamping fit manner. Compared with the prior art method of first disassembling the torso body and then assembling the joints, the number of assembly steps is reduced, the assembly effect is effectively improved, and the labor intensity of the assembly personnel is also reduced. It can be applied to the joint connections of toys such as dolls, animals, and robots; in addition, when the installation part and the installation hole position are in a clamped fit state, the installation part can also be directly disassembled from the installation hole position to further facilitate the user and the assembly personnel to disassemble.

[0015] During disassembly, first disassemble the first housing and the second housing, and then the mounting member is separated from the mounting hole position, thus completing the disassembly of the mounting member and the mounting hole position. The disassembly steps are simple.

[0016] In addition, after the mounting member and the mounting hole position are snap-fitted, the first joint body and the second joint body can be a rotatable structure or a non-rotatable structure. The selection of this rotatable structure or non-rotatable structure can be preset during the processing according to different production requirements. Brief Description of the Drawings

[0039] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments. The content mentioned in the implementation mode does not limit the present invention.

[0040] Reference Figures 1 to 8 , in an embodiment, a toy doll is provided, including a trunk body 4, a hand member 5 and a leg member 6. The trunk body 4 and the leg member 6 are connected through a joint structure. The first joint body 1 is detachably installed below the trunk body 4, and the leg member 6 is connected to the second joint body 2.

[0041] Specifically, the leg member 6 and the second joint body 2 are integrally formed to improve the structural strength of the leg member 6 and the second joint body 2 and ensure its service life.

[0042] Further specifically, the number of the hand members 5 and the leg members 6 is two, and the number of the first connection components is equal to that of the leg members 6.

[0043] Applying the joint structure to the toy doll, when assembling the toy doll, there is no need to disassemble the trunk body 4. It can be directly clamped and matched through the installation part 20 and the installation hole position 10, which reduces the assembly steps compared with the prior art and greatly improves the assembly efficiency.

[0044] In one embodiment, the hand member 5 is connected to the torso body 4 through a second connection assembly. The second connection assembly includes a plug shaft 50 rotatably connected to the hand member 5, a plug hole 40 formed in the torso body 4 and in plug-in fit with the plug shaft 50, and a second limiting member provided on the plug shaft 50 for limiting the position of the plug shaft 50.

[0045] Specifically, the number of the second connection assemblies is equal to the number of the hand members 5.

[0046] Further specifically, the plug shaft 50 is rotatably connected to the plug hole 40, so as to further imitate the rotatable movement of the human hand joint. Of course, the plug shaft 50 and the plug hole 40 can also be in a non-rotatable connection structure. The selection of this rotatable structure or non-rotatable structure can be preset during the processing according to different production requirements.

[0047] Still further specifically, the torso body 4 includes a third housing 42 and a fourth housing 43 which are assembled in a butting manner. One part of the plug hole 40 is formed in the third housing 42, and the other part of the plug hole 40 is formed in the fourth housing 43.

[0048] During the assembly process, the plug shaft 50 is directly inserted into the plug hole 40, and the second limiting member is used to limit the plugging position of the plug shaft 50. In this way, the installation of the hand member 5 is completed without pre-disassembling the torso body 4, greatly improving the assembly efficiency. In addition, the hand member 5 is provided with a second avoidance sliding groove 54 for the plug shaft 50 to rotate; in this way, the connection between the hand member 5 and the plug shaft 50 can be set to be more compact, and the movement of the human hand joint can be simulated more realistically.

[0049] In one embodiment, the second limiting member includes a guiding plugging portion 51 provided on the side of the plug shaft 50 away from the hand member 5 and a plugging limiting portion 52 provided on the side of the plug shaft 50 close to the hand member 5. A plugging limiting cavity 53 is formed between the guiding plugging portion 51 and the plugging limiting portion 52. An elastic limiting portion 41 is provided at the inner end of the plug hole 40. When the plug shaft 50 is in plug-in fit with the plug hole 40, the elastic limiting portion 41 and the plugging limiting cavity 53 are used in cooperation to limit the plugging position of the plug shaft 50.

[0050] Specifically, the shape of the guiding insertion part 51 is conical, and the maximum diameter of the guiding insertion part 51 is larger than the diameter of the insertion hole 40. The conical end of the guiding insertion part 51 is located on the side of the guiding insertion part 51 away from the hand member 5. In this way, during the process of installing the insertion shaft 50 into the insertion hole 40, the guiding insertion part 51 plays a role in guiding and installing, so as to solve the problem that the insertion shaft 50 cannot be accurately installed into the insertion hole 40 due to the hand member 5 blocking the line of sight during the assembly process.

[0051] Further specifically, the insertion limiting part 52 is a ring sleeved on the insertion shaft 50. The diameter of the conical guiding insertion part 51 is larger than the diameter of the insertion shaft 50, and the diameter of the insertion limiting part 52 is larger than the diameter of the guiding insertion part 51. In this way, the insertion limiting cavity 53 is formed by the diameter difference between the conical guiding insertion part 51 and the insertion shaft 50 and the diameter difference between the insertion limiting part 52 and the guiding insertion part 51.

[0052] Still further specifically, the width of the insertion hole 40 gradually decreases from the outer end to the inner end (that is, from the side close to the hand member 5 to the side away from the hand member 5). In this way, the larger design of the outer end can make the guiding insertion part 51 enter the insertion hole 40 more easily. As the insertion hole 40 gradually decreases and is combined with the design of the conical guiding insertion part 51, it is not only convenient for the assembler to assemble, but also ensures the accuracy of the installation position of the guiding insertion part 51, with strong practicability. In addition, an insertion limiting boss 55 is provided in the insertion hole 40 to cooperate with the insertion limiting part 52 to limit the insertion depth of the insertion shaft 50, so as to avoid the phenomenon of structural failure and damage caused by excessive insertion depth.

[0053] Even further specifically, the elastic limiting part 41 includes a first elastic limiting claw 44 and a second elastic limiting claw 45 respectively arranged at the upper and lower ends of the insertion hole 40, and a fixing cavity 46 for installing the insertion shaft 50 is provided between the first elastic limiting claw 44 and the second elastic limiting claw 45. The diameter of the fixing cavity 46 is larger than the diameter of the insertion shaft 50. When the insertion shaft 50 is inserted and matched with the insertion hole 40, the first elastic limiting claw 44, the second elastic limiting claw 45 and the insertion limiting cavity 53 are used in cooperation to fix the insertion shaft 50.

[0054] In the initial state, the diameter of the fixed cavity 46 is smaller than the maximum diameter of the conical guide insertion part 51. When the conical guide insertion part 51 is inserted into the insertion hole 40 (i.e., when the hand member 5 is installed), the first elastic limiting claw 44 and the second elastic limiting claw 45 will be gradually pushed outwards. When the diameter of the fixed cavity 46 is greater than or equal to the maximum diameter of the conical guide insertion part 51, the guide insertion part 51 continues to move until the guide insertion part 51 moves out of the fixed cavity 46 and the insertion shaft 50 is located in the fixed cavity 46. At this time, due to the elastic action of the first elastic limiting claw 44 and the second elastic limiting claw 45, they are reset. In this way, the up and down positions of the insertion shaft 50 are limited by the first elastic limiting claw 44 and the second elastic limiting claw 45. When the guide insertion part 51 continues to be inserted and the limiting boss 55 blocks the continuous movement of the insertion limiting part 52, this is the maximum insertion stroke of the insertion shaft 50. At the same time, the left and right positions of the insertion shaft 50 are limited by the guide insertion part 51 and the insertion limiting part 52. In this way, the installation of the second connection component is completed. The plug-in installation method of the hand member 5 greatly reduces the assembly steps, reduces the assembly difficulty, and effectively improves the assembly efficiency compared with the existing installation method of first disassembling the torso body and then assembling the hand member 5.

[0055] In addition, when the hand member 5 needs to be disassembled from the torso body 4, the torso body 4 needs to be disassembled first, and then the second connection component needs to be disassembled to complete the disassembly of the hand member 5. In this way, when the hand member 5 and the torso body 4 are in the assembled state, it cannot be directly pulled out to ensure the installation stability.

[0056] In an embodiment, the joint structure includes a first joint body 1, a second joint body 2, and a first connection component for connecting the first joint body 1 and the second joint body 2. The first connection component includes an installation hole position 10 opened on the first joint body 1, an installation part 20 provided on the second joint body 2 and used for snap-fitting with the installation hole position 10, and a first limiting part 3 for limiting the snap-fitting position of the installation part 20 when the installation part 20 is snap-fitted with the installation hole position 10.

[0057] Specifically, the first joint body 1 includes a first shell 14 and a second shell 15 which are oppositely installed, and a part of the installation hole position 10 is opened on the first shell 14, and another part of the installation hole position 10 is opened on the second shell 15.

[0058] During assembly (at this time, the first shell 14 and the second shell 15 are in a state of being matched and installed), the mounting member 20 is mounted on the mounting hole 10 by snap-fitting, and the snap-fitting position of the mounting member 20 is limited by the first limiting member 3. In this state, the mounting member 20 cannot be directly removed from the mounting hole 10, so as to ensure the stability of the snap-fitting installation of the mounting member 20 and the mounting hole 10, so that the first connection assembly can be used in a high-intensity environment (such as vigorously shaking, pulling the first joint body 1 and / or the second joint body 2, etc.). The second joint body 2 is installed on the first joint body 1 by a snap-fitting method. Compared with the prior art method that requires first disassembling the torso body 4 and then assembling the joints, the steps required for assembly are reduced, the assembly effect is effectively improved, and the labor intensity of the assemblers is reduced. It can be applied to the joint connections of toys such as dolls, animals, and robots. In addition, when the mounting piece 20 and the mounting hole 10 are in a snap-fitting state, the mounting piece 20 can also be directly removed from the mounting hole 10, so as to further facilitate disassembly by users and assemblers.

[0059] During disassembly, the first shell 14 and the second shell 15 are disassembled first, and then the mounting member 20 is separated from the mounting hole 10, so that the disassembly of the mounting member 20 and the mounting hole 10 is completed, and the disassembly steps are simple.

[0060] In addition, after the mounting member 20 is snap-fitted with the mounting hole 10, the first joint body 1 and the second joint body 2 are a rotatable structure or a non-rotatable structure. The choice of this rotatable structure or non-rotatable structure can be pre-set during the processing according to different production requirements.

[0061] In one embodiment, the mounting hole 10 includes a snap-fitting hole 11 for snap-fitting with the mounting member 20 and a mounting hole 12 connected to the snap-fitting hole 11; when the mounting member 20 enters the snap-fitting hole 11 from the mounting hole 12, the first limiting member 3 is arranged in the mounting hole 12 to limit the snap-fitting position of the mounting member 20.

[0062] Specifically, the diameter of the snap-in hole 11 is smaller than the diameter of the mounting hole 12, and the snap-in hole 11 is located below the mounting hole 12; during assembly, the mounting member 20 enters from the mounting hole 12, and then moves into the snap-in hole 11 to snap-in with it. At this time, the first limiting member 3 limits the snap-in position of the mounting member 20 in the mounting hole 12 to prevent the mounting member 20 from moving out of the snap-in hole 11, thereby effectively ensuring the connection stability of the snap-in structure between the mounting member 20 and the snap-in hole 11.

[0063] In addition, the clamping hole 11 may also be located above the mounting hole 12 . The specific installation steps of this method are the same as those of the above-mentioned clamping hole 11 being located below the mounting hole 12 , and will not be described in detail here.

[0064] In one embodiment, the mounting member 20 includes a clamping shaft 21 and a clamping limit portion 22, the side of the clamping shaft 21 away from the second joint body 2 is fixedly connected to the clamping limit portion 22, and the side of the clamping shaft 21 close to the second joint body 2 is rotatably connected to the second joint body 2; when the mounting member 20 is clamped and matched with the mounting hole 10, the clamping shaft 21 is inserted into the clamping hole 11.

[0065] Specifically, the shape of the clamping limit part 22 is cylindrical, and the axis of the clamping limit part 22 is parallel to the axis of the clamping shaft 21. In addition, the diameter of the clamping shaft 21 is smaller than the diameter of the clamping limit part 22, so that the outer circumferential surface of the clamping limit part 22 and the outer circumferential surface of the clamping shaft 21 form a height difference to form a clamping limit cavity 24 for clamping with the clamping hole 11. At the same time, the diameter of the clamping hole 11 is larger than the diameter of the clamping shaft 21 and smaller than the diameter of the clamping limit part 22, and the diameter of the clamping limit part 22 is smaller than the diameter of the mounting hole 12, so as to facilitate the installation of the clamping limit part 22 in the mounting hole 12 and facilitate the rotatable installation of the clamping shaft 21 in the clamping hole 11.

[0066] It is further specified that the second joint body 2 is provided with a first avoidance slot 25 for the rotation of the clamping shaft 21. This makes the connection between the second joint body 2 and the clamping shaft 21 more compact and can simulate human joint movements more realistically.

[0067] To be further described in detail, the second joint body 2 is provided with a support portion 26 for supporting the clamping limit portion 22. Since the outer circumferential surface of the clamping limit portion 22 forms a height difference with the outer circumferential surface of the clamping shaft 21, when the mounting member 20 is clamped and matched with the mounting hole 10, the clamping limit portion 22 is supported by the support portion 26 to prevent the clamping limit portion 22 from tilting and tilting, and the downward movement stroke of the clamping shaft 21 is also limited.

[0068] During assembly, the clamping limit portion 22 is inserted into the mounting hole 12 until the clamping shaft 21 is located in the mounting hole 12, and then the clamping shaft 21 is moved into the clamping hole 11 for clamping engagement. At this time, the first limit member 3 limits the clamping position of the mounting member 20 in the mounting hole 12, thereby limiting the upper and lower positions of the clamping shaft 21, and limiting the left and right positions of the clamping shaft 21 through the clamping limit portion 22 and the second joint body 2, thereby effectively ensuring the installation stability of the clamping shaft 21.

[0069] In one embodiment, a first guide portion 23 is provided on a side of the clamping and limiting portion 22 away from the second joint body 2 to facilitate the clamping and limiting portion 22 to enter the mounting hole 12 .

[0070] Specifically, the first guide portion 23 is conical, and the axis of the first guide portion 23 is parallel to the axis of the clamping shaft 21; the first guide portion 23 is used to solve the problem that the clamping limit portion 22 cannot be accurately installed in the mounting hole 12 due to the second body blocking the line of sight during the assembly process. During the assembly process, when the first guide portion 23 is located near the mounting hole 12, it can be guided into the mounting hole 12 by the conical surface of the first guide portion 23 to ensure that the clamping limit portion 22 can be quickly and accurately installed in the mounting hole 12.

[0071] In one embodiment, the first limiting member 3 includes an elastic arm 30 and a fixing portion 31 and a limiting stop portion 32 respectively disposed at both ends of the elastic arm 30 , the limiting stop portion 32 is disposed in the mounting hole 12 , and the first joint body 1 is provided with a fixing column 33 for mounting the fixing portion 31 .

[0072] In the initial state, the limit stopper 32 is located in the mounting hole 12. When the mounting member 20 is inserted into the mounting hole 12, the limit stopper 32 will be squeezed and pushed by the mounting member 20 to move toward the inside of the first joint body 1. At this time, the limit stopper 32 moves with the connection between the fixing portion 31 and the fixing column 33 as a fulcrum, and drives the elastic arm 30 to move so that it generates elastic deformation to form energy storage. When the mounting member 20 moves from the mounting hole 12 to the clamping hole 11, the mounting member 20 and the clamping hole 11 are clamped together. At the same time, the elastic arm 30 uses the energy storage to drive the limit stopper 32 to reset until the limit stopper 32 is located in the mounting hole 12 to limit the clamping position of the mounting member 20. The design is ingenious and the structure is stable and reliable.

[0073] In one embodiment, one implementation method is: the fixing portion 31 is fixedly connected to the fixing column 33. Such a structural design can enable the elastic arm 30 to be sufficiently deformed to form energy storage, thereby effectively ensuring the reset accuracy of the limit baffle, and further ensuring the clamping stability of the clamping matching structure of the mounting member 20 and the mounting hole 10.

[0074] Another embodiment: the fixing part 31 is rotatably connected to the fixing column 33, and the first joint body 1 is provided with a travel limiting part 13 for limiting the rotatable travel of the fixing part 31. Specifically, the travel limiting part 13 is a limit horizontal plate installed on the first joint body 1. Such a structural design enables the first limiter 3 to have a certain rotatable space, and the rotatable range is relatively small, so as to avoid the phenomenon of short service life of the elastic arm 30 and / or severe wear between the fixing part 31 and the fixing column 33 due to the rigid connection between the fixing part 31 and the fixing column 33.

[0075] In one embodiment, a second guide portion 34 is provided on a side of the position limiting stop portion 32 close to the second joint body 2 to facilitate the installation member 20 to enter the engaging hole 11 from the installation hole 12 .

[0076] Specifically, the second guide portion 34 is an arcuate guide surface, and the distance from the left side to the right side of the limit stop 32, that is, the distance from the side of the limit stop 32 away from the second joint body 2 to the arcuate guide surface, gradually decreases from top to bottom.

[0077] In the initial state, the limit stop portion 32 is located in the mounting hole 12. When the mounting component 20 is installed in the mounting hole 12, the mounting component 20 will apply an extrusion thrust to the limit stop portion 32. At this time, the limit stop portion 32 gradually moves toward the inside of the first joint body 1. At the same time, the mounting component 20 will gradually slide down along the arc-shaped guide surface until the mounting component 20 enters the clamping hole 11. In this way, the second guide portion 34 effectively improves the installation convenience of the mounting component 20, and the practicality is strong.
