Description

Technical Field

[0001] The utility model relates to the field of toys, in particular to a high-stability pipe fitting connection structure. Background Art

[0002] Toy building components are very popular, and users can use them to build a variety of structures and models. In order to improve the building flexibility of toy building components, expand the plane building into three-dimensional building, fully develop the imagination of users, and improve their thinking ability, the existing toy building components are designed to have multiple dimensions and angles through a split spherical pipe connection structure.

[0003] For example, the prior application named "A toy building assembly" with application number 202122639696.0, has a connecting element that can be snap-connected to the first bayonet of the first connecting rod collecting element, and can be connected to the adapter element through the first tube cavity. Specifically, after the connecting element is inserted into the first bayonet, it is rotated 90° to limit the position and cannot be pulled out, so that the two adapter elements can be clamped on both sides of the first connecting rod collecting element through the connecting element to form a spherical connection structure.

[0004] However, the above-mentioned existing spherical pipe connection structure has the following defects: First, there is no stable axial limit between the connecting element and the first tube cavity of the adapter element, which causes the adapter element to easily fall off during the process of building or plugging in and out the connecting rod element, resulting in poor overall stability of the spherical connection structure; Second, there is no stable circumferential limit between the adapter element and the first connecting rod collecting element, which causes the connecting element to rotate and lose the limit and detach from the first bayonet during the process of building or plugging in and out the connecting rod element, thereby causing the constructed model to disintegrate, greatly affecting the overall stability of the spherical connection structure.

[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0035] refer to Figure 1-8 , a high-stability pipe connection structure, comprising:

[0036] The collecting member 1 is provided with a plurality of first connecting grooves 11 for centrally connecting the pipes in the circumferential direction. Specifically, the first connecting grooves 11 are arranged transversely. A first bayonet 12 is provided in the middle of the collecting member 1. Limiting structures 4 are provided at both ends of the first bayonet 12. A plurality of limiting grooves 13 are provided at intervals on the outer sides of both ends of the first bayonet 12 in the circumferential direction.

[0037] The connecting member 2 has protrusions on both sides to form a protrusion 21. The connecting member 2 can be inserted into the first bayonet 12 through the protrusion 21 and then rotated to be limited by the limiting structure 4 to connect with the collecting member 1. At least one end of the connecting member 2 is exposed to form a clamping portion 22. A positioning portion 23 is recessed between the clamping portion 22 and the protrusion 21.

[0038] At least one adapter 3 has a protruding adapter portion 31 on one side and a contact surface 32 on the other side. The adapter portion 31 is provided with a plurality of second connecting grooves 33 for connecting the pipe. Specifically, the second connecting grooves 33 are arranged obliquely to realize a three-dimensional adapter of the pipe. A clamping hole 34 adapted to the clamping portion 22 is penetrated through the middle of the adapter 3. A plurality of buckles 341 are arranged at circumferential intervals on the inner wall of the clamping hole 34. A plurality of limiting portions 321 corresponding to the limiting grooves 13 are protruding from the contact surface 32. After the connecting member 2 is connected to the collecting member 1, the adapter 3 is sleeved on the clamping portion 22 through the clamping hole 34, and the contact surface 32 is contacted on the collecting member 1. A plurality of buckles 341 are engaged and clamped into the positioning portion 23 to form an axial limit, and a plurality of limiting portions 321 are inserted into a plurality of limiting grooves 13 to form a circumferential limit. In this embodiment, two adapters 3 are provided, and two clamping parts 22 are provided and arranged up and down. After the connecting member 2 is connected to the collecting member 1, the two adapters 3 are respectively sleeved on the clamping parts 22 and the abutting surfaces 32 are clamped and abutted against the upper and lower sides of the collecting member 1 to form a spherical connection structure.

[0039] With the arrangement of the above-mentioned structure, the present application forms an axial limit by means of a plurality of snap hooks 341 which are engaged and clamped into the positioning portion 23, thereby achieving an axial limit between the clamping portion 22 and the clamping hole 34, and further ensuring a stable connection between the connector 2 and the adapter 3, thereby preventing the adapter 3 from falling off during the process of building or plugging in and out the pipe, and improving the overall stability of the pipe connection structure; and then forms a circumferential limit by means of a plurality of limiting portions 321 which are limitedly inserted into a plurality of limiting grooves 13, thereby achieving a stable circumferential limit between the adapter 3 and the collecting member 1 on the basis of the axial limit between the clamping portion 22 and the clamping hole 34, thereby preventing the adapter 3 from rotating and driving the connector 2 to rotate and lose the limit and detach from the first clamping port 12 during the process of building or plugging in and out the pipe, and causing the constructed model to disintegrate, and further improving the overall stability of the pipe connection structure.

[0040] Under the premise of the above-mentioned axial limitation and circumferential limitation, the adapter 3 is difficult to remove after being sleeved on the clamping part 22. In order to facilitate the user to remove the adapter 3 and avoid the user's forced removal causing damage to the connecting member 2 or the adapter 3, the upper and lower sides of the collecting member 1 are recessed to form a plurality of makeshift openings 14 arranged between adjacent first connecting grooves 11, and the abutting surface 32 is abutted on the collecting member 1 and spaced apart from the makeshift openings 14. Therefore, after the adapter 3 is sleeved on the clamping portion 22 and is axially limited and circumferentially limited, one side of the adapter 3 can be easily pried open through the yielding opening 14 on one side so that the limiting portion 321 on one side is disengaged from the limiting groove 13 and the buckle 341 on one side is disengaged from the positioning portion 23. The remaining limiting portion 321 and the buckle 341 can also be easily disengaged from the limiting groove 13 and the positioning portion 23, so that the adapter 3 can be easily disassembled, thereby improving the convenience of disassembly of the adapter 3, avoiding damage to the connecting member 2 or the adapter 3 during the disassembly process, improving the use stability of the pipe connection structure, and improving the user experience.

[0041] In order to prevent the internal negative pressure from causing the connection to be too tight when the first connecting groove 11 and the second connecting groove 33 are connected to the pipe fitting, and the user is injured under the action of inertia when pulling out the pipe fitting with force, the first connecting groove 11 is provided with a first pressure relief port 111 connected to the upper and lower sides of the collecting member 1 on both sides of the bottom of the groove, and the second connecting groove 33 is provided with a second pressure relief port 331 connected to the abutting surface 32 on one side of the bottom of the groove, and the first pressure relief port 111 is connected to the corresponding limiting groove 13, and the abutting surface 32 is recessed to form a pressure relief port 331 provided on the limiting portion 321 is far from the pressure relief notch 322 on one side of the second pressure relief port 331. After the abutting surface 32 abuts against the collecting member 1, the gap between the limiting portion 321 and the limiting slot 13 is set to form a pressure relief gap 5. The pressure relief notch 322 is connected to the outside world corresponding to the two adjacent giving way ports 14. The first connecting slot 11 corresponds to the second connecting slot 33. The first pressure relief port 111 is connected to the second pressure relief port 331 and is connected to the pressure relief notch 322 through the pressure relief gap 5. Therefore, when the pipe is inserted into the first connecting slot 11 or the second connecting slot 33, the air in the first connecting slot 11 and the second connecting slot 33 can be discharged from the pressure relief notch 322 to the outside world through the pressure relief ports, so as to avoid the pipe being too tightly inserted into the first connecting slot 11 and the second connecting slot 33 under the action of negative pressure, resulting in the situation that the user falls to or is stabbed by the pipe under the action of inertia when pulling out the pipe with force, thereby improving the safety and stability of the pipe connection structure when in use.

[0042] In order to improve the connecting groove of the pipe connection structure, a third connecting groove 24 is provided at the end of the clamping portion 22, and a plurality of third pressure relief ports 241 are provided on the side wall of the third connecting groove 24, and a fourth pressure relief port 332 is provided on the other side of the bottom of the plurality of second connecting grooves 33. After the abutting surface 32 abuts against the collecting member 1, the third pressure relief port 241, the fourth pressure relief port 332, the second pressure relief port 331, the pressure relief gap 5, and the pressure relief groove are connected in sequence. Thereby, the number and directions of the pipes that can be connected by the pipe connection structure are increased through the third connecting groove 24. At the same time, in order to avoid the internal negative pressure when the pipe is connected to the third connecting groove 24 causing the connection to be too tight, when the pipe is inserted into the third connecting groove 24, the air in the third connecting groove 24 can be discharged from the pressure relief groove 322 to the outside through each pressure relief port, so as to avoid the pipe being too tightly inserted into the third connecting groove 24 under the action of negative pressure, resulting in the situation that the user falls on or is stabbed by the pipe due to inertia when pulling out the pipe with force, thereby further improving the safety and stability of the pipe connection structure when in use.

[0043] In order to prevent negative pressure from being generated in each first connecting groove 11 while improving the first connecting groove 11 of the collecting member 1, the number of the first connecting grooves 11 is greater than the number of the second connecting grooves 33, the number of the limiting grooves 13 and the first connecting grooves 11 are consistent and correspond one to one, the number of the limiting portions 321 and the second connecting grooves 33 are consistent and correspond one to one, and after the abutting surface 32 abuts against the collecting member 1, the first pressure relief port 111 of the first connecting groove 11 that does not correspond to the second connecting groove 33 is connected to the outside through the limiting groove 13 in which the limiting portion 321 is not inserted without being limited.

[0044] In order to prevent the pipe fitting from being difficult to be pulled out after being inserted due to excessive friction between the pipe fitting and the first connection groove 11, the second connection groove 33, and the third connection groove 24, the inner walls of the first connection groove 11, the second connection groove 33, and the third connection groove 24 are all raised to form a plurality of annularly spaced clamping ridges 6. Thus, by providing a plurality of clamping ridges 6, when the pipe fitting is inserted into the first connection groove 11, the second connection groove 33, or the third connection groove 24, the existing surface contact with the inner wall thereof is replaced with line contact with the plurality of clamping ridges 6, thereby reducing the friction between the pipe fitting and each connection groove, so as to facilitate the insertion and removal of the pipe fitting while ensuring the connection strength between the pipe fitting and each connection groove, thereby preventing the pipe fitting from being injured when the user pulls out the pipe fitting with force due to the excessively tight connection between the pipe fitting and each connection groove, and further improving the safety and stability of the pipe fitting connection structure when in use.

[0045] In order to improve the stability of the plurality of buckles 341, the outer wall of the clamping part 22 is set to be polygonal and is concave with a plurality of positioning grooves 221 arranged at intervals in an annular manner. The clamping hole 34 is adapted to the clamping part 22 and is provided with a plurality of positioning ribs 342 in one end close to the abutting surface 32. The plurality of positioning ribs 342 are arranged in pairs corresponding to one positioning groove 221. The buckles 341 are arranged between each group of positioning ribs 342. One end of the plurality of buckles 341 is fixedly connected to the clamping hole 34, and the other end extends toward the side close to the abutting surface 32 and then protrudes toward the outside of the positioning ribs 342 to form a hook portion. The buckles 341 are made of elastic material. Thus, auxiliary positioning is achieved by the sleeve arrangement of the plurality of positioning ribs 342 on the adapter 3, and the plurality of positioning ribs 342 can prevent the buckle 341 from being deformed due to excessive pressure, and only the hook extends out of the positioning ribs 342 to cooperate with the positioning part 23 for clamping.

[0046] Specifically, the limiting structure 4 includes a snap ring 41 provided at one end of the first bayonet 12 and adapted to the outer wall of the connecting member 2, and a blocking portion 42 provided parallel and horizontally on both sides of the other end of the first bayonet 12. A connecting channel is formed between the two blocking portions 42. The connecting member 2 is inserted into the first bayonet 12 through the connecting channel through the protrusion 21 and rotated until the protrusion 21 is limited by the snap ring 41 and the blocking portion 42 and then connected to the collecting member 1.

[0047] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
