[0001] This utility model relates to the technical field of pipeline connection, and in particular to a pipeline connection structure. Background Technology

[0002] In order to connect two independent pipelines, a pipeline connection structure is set between the two pipelines. The two pipelines extend to the two connecting ports of the pipeline connection structure, thereby forming a fluid channel, allowing fluids (such as gas, liquid, etc.) to flow freely between the two pipelines.

[0003] In some related technologies, such as patent publication number CN118517590A, a quick-connect structure for pipes is disclosed, including a first pipe head, a second pipe head, a first clamp, a second clamp, and fasteners. The first and second pipe heads are respectively connected to the ends of two different pipes. The first and second clamps are respectively clamped onto the first and second pipe heads. Multiple fasteners are provided, and they are located between the first and second clamps. This solution does not disclose how to fix the first and second pipe heads to the two pipes respectively, which can easily lead to pipe detachment and cannot guarantee that the pipes can be stably connected to the pipe heads.

[0042] To address the technical problem in existing technologies where pipes are prone to separation from the pipe ends of pipe connection structures, and where it is impossible to guarantee a stable connection between pipes and pipe ends, this utility model provides a pipe connection structure.

[0043] The following describes in detail the specific structure of a pipeline connection structure provided by an embodiment of this utility model, according to the appendix. Figure 1-5 As shown, the specific structure of this pipeline connection includes:

[0044] according to Figure 1 and Figure 2 As shown, two interconnected connecting components 1a: by detachably connecting two independent pipes 15 to the two connecting components 1a respectively, the two independent pipes 15 can be interconnected, and fluids (such as gas, liquid, etc.) can flow freely between the two pipes 15. Specifically, each connecting component 1a includes a connecting member 11, a locking component 12, and a pressing sleeve 13.

[0045] according to Figures 2-4 As shown, the connecting member 11 is hollow and has a flow cavity 111 and a connecting cavity 112; the flow cavities 111 of each connecting component 1a are interconnected; the connecting cavity 112 and the flow cavity 111 are connected through a connecting port 113.

[0046] Specifically, if it is necessary to connect two independently configured pipes 15 to each other, one end of the first pipe 15 is first inserted into the connecting cavity 112 of the first connecting component 1a, and one end of the second pipe 1b is simultaneously inserted into the connecting cavity 112 of the second connecting component 1b. Since the connecting components are interconnected, the flow cavities 111 of the connecting components are interconnected. When the fluid in the first pipe 15 is flowing, the flow can go from the first pipe 15 through the flow cavity 111 of the first connecting component 1a to the flow cavity 111 of the second connecting component 1b, and finally flow into the second pipe 15. This arrangement ensures that the fluid can flow continuously between the two pipes 15.

[0047] according to Figure 2 and Figure 3 As shown, the locking assembly 12 includes a locking cover 121 and a clamping part 122. The locking cover 121 is axially movable and sleeved on the outside of the connecting member 11. The clamping part 122 is disposed inside the locking cover 121 and has a through locking cavity 124 for passing through the locking cavity 124 and connecting to the connecting port 113. An inclined surface 123 is formed on the outside of the clamping part 122.

[0048] Specifically, to ensure that the first pipe 15 can be stably inserted into the connecting cavity 112 of the first connecting assembly 1a, and the second pipe 15 can be stably inserted into the connecting cavity 112 of the second connecting assembly 1a, to prevent the pipes 15 from separating from their respective connecting cavities 112, after one end of the first pipe 15 and the second pipe 15 are respectively inserted into the connecting cavities 112 of the first connecting assembly 1a and the second connecting assembly 1b, the clamping parts 122 are respectively sleeved on the outside of the pipes 15. That is, the pipes 15 need to pass through the locking cavity 124 in the clamping part 122 and extend to the deepest part of the connecting cavity 112 before they can be connected to the communication port 113. By pushing the locking cover 121 to move along its axial direction, since the clamping part 122 is located in... The inner bottom surface of the locking cover 121 can drive the clamping part 122 to move when the locking cover 121 moves. When the clamping part 122 moves to abut against the pressing sleeve 13, that is, when the outer side of the clamping part 122 abuts against the inner side of the pressing sleeve 13, a certain pushing force is released on the clamping part 122 by the pressing seat, so that the clamping part 122 can clamp the outer wall of the pipe 15 more firmly, so that one end of each pipe 15 is fixedly inserted into the connecting cavity 112 of each connecting component, effectively preventing the pipe 15 from separating from the connecting cavity 112 of the connecting component due to some vibration or pressure change during the flow of fluid. At this time, free flow of fluid can be achieved between the first pipe 15 and the second pipe 15.

[0049] according to Figure 3 and Figure 4As shown, the pressing sleeve 13 is sleeved on the outside of the clamping part 122, and the inner side of the pressing sleeve 13 has an annular inclined surface 131 for conforming to the inclined surface 123.

[0050] Specifically, to ensure that each clamping part 122 can be more securely clamped to the outer wall of the pipe 15 and to prevent the pipe 15 from easily falling off, when the locking cover 121 moves upward along its axial direction, it pushes the clamping part 122 to move upward as well, until the clamping part 122 moves to the point where its outer side can abut against the inner side of the pressing sleeve 13. Since the pressing sleeve 13 is sleeved between the outer side of the clamping part 122 and the cavity wall of the connecting cavity 112, the pressing sleeve 13 can release the pushing pressure on the clamping part 122. More specifically, at this time... When the annular inclined surface on the inner side of the pressing sleeve 13 is in contact with the inclined surface 123 on the outer side of the clamping part 122, a radial pushing force is applied to the clamping part 122. That is, when the clamping part 122 is squeezed by the pressing sleeve 13, it can generate a radial contraction force. When the locking cover 121 rises to the specified height, the pressing sleeve 13 can squeeze the clamping part 122 to be fixedly locked to the outer wall of the pipe 15, ensuring that each pipe 15 can be fixedly inserted into the connecting cavity 112 of each connecting component, preventing the two from separating.

[0051] In the above embodiments, if it is necessary to separate the pipe 15 from the connecting component, simply move the locking cover 121 downward along its axis to push the clamping part 122 to follow the downward movement until the annular inclined surface on the inner side of the pressing sleeve 13 separates from the inclined surface 123 on the outer side of the clamping part 122. At this time, the clamping part 122 can no longer be squeezed by the pressing sleeve 13, and the clamping part 122 can no longer fix and lock the pipe 15. Then the pipe 15 can be pulled out from the connecting cavity 112. This setting realizes the quick clamping and release of the pipe 15, and the overall operation is simple and reliable.

[0052] It should be noted that the locking cover 121 is detachably disposed on the outer wall of the connecting member 11. If the internal components need to be replaced, the locking cover 121 only needs to be removed from the outside of the connecting member 11. At this time, the pressing sleeve 13 and the sealing sleeve 14 can be removed from the connecting cavity 112. This design can improve the convenience of the entire pipeline 15 connection structure in the disassembly and assembly process.

[0053] according to Figure 5 As shown, in some specific embodiments, the clamping part 122 includes a plurality of elastically arranged buckles 1221, each buckle 1221 being spaced apart within the locking cover 121, and each buckle 1221 being arranged in a circumferential array to form a locking cavity 124 surrounding the outer wall of the pipe 15; each buckle 1221 has an inclined surface 123 formed on one side.

[0054] Specifically, the clips 1221 are made of elastic material, thus possessing a certain degree of deformation capability. When the pipe 15 is inserted into the locking cavity 124, the clips 1221 undergo elastic deformation after being squeezed by the pipe 15, thereby providing sufficient space for the pipe 15 to pass through. Simultaneously, when the inclined surfaces 123 of each clip 1221 are pressed by the annular inclined surface of the pressing sleeve 13, a radial pushing force is uniformly applied to the pipe 15, ensuring that each clip 1221 simultaneously adheres to the outer wall of the pipe 15, thus ensuring that the pipe 15 is firmly clamped. Since the multiple clips 1221 are distributed in a circumferential array, they can evenly surround the outer wall of the pipe 15. This arrangement ensures that the pipe 15 is subjected to uniform clamping force in all directions, thereby forming a uniform locking force on the outer wall of the pipe 15, preventing the pipe 15 from loosening or falling off due to uneven force.

[0055] according to Figure 4 and Figure 5 As shown, in a further embodiment, each buckle 1221 has an arcuate surface 1222 on the side away from the inclined surface 123 for fitting against the outer wall of the pipe 15.

[0056] Specifically, by providing an arc-shaped surface 1222 on one side of each clip 1221, the contact area between the clip 1221 and the outer wall of the pipe 15 is increased, thereby providing a stronger locking force. This setting helps to ensure that the pipe can maintain its stability better when subjected to external forces, preventing the pipe from loosening or falling off. In addition, by fitting the arc-shaped surface 1222 against the outer wall of the pipe 15, a certain sealing effect can be achieved. That is, when the clip 1221 is squeezed, the arc-shaped surface 1222 of each clip 1221 can fit tightly against the outer wall of the pipe 15, thereby preventing fluid leakage.

[0057] In some specific embodiments, the outer side wall of the connecting member 11 is provided with a first thread; the inner side wall of the locking cover 121 is provided with a second thread that mates with the first thread.

[0058] Specifically, in order to drive the locking cover 121 to move upward or downward along its axial direction, the second thread of the locking cover 121 is connected to the first thread of the connecting member 11. Thus, when the locking cover 121 is pushed to rotate clockwise, the helical action of the first and second threads converts the rotational motion of the locking cover 121 into linear movement along the axial direction, so that the locking cover 121 can move upward steadily along its axial direction until the inclined surface 123 of each buckle 1221 is in contact with the annular inclined surface of the pressing sleeve 13. Conversely, when the locking cover 121 is pushed to rotate counterclockwise, the locking cover 121 can move downward steadily along its axial direction until the inclined surface 123 of each buckle 1221 separates from the annular inclined surface of the pressing sleeve 13. The first and second threads are used to control the upward or downward movement of the locking cover 121 to lock or release the pipeline 15.

[0059] It should be noted that when disassembling or assembling the locking cover 121, simply rotate the locking cover 121. Through the action of the first thread and the second thread, the locking cover 121 can be quickly disassembled and removed or fixedly assembled to the outer wall of the connecting member 11.

[0060] according to Figure 3 As shown, in some specific embodiments, the outer wall of the connecting member 11 is provided with a limiting part 115 for limiting the movement range of the locking cover 121.

[0061] Specifically, in order to prevent the locking cover 121 from moving excessively and causing the pipe 15 to be crushed, a limiting part 115 is provided on the outer wall of the connecting member 11. When the locking cover 121 moves upward along its axial direction to a certain distance, the limiting part 115 abuts against the locking cover 121 to lock the locking cover 121 and prevent the locking cover 121 from continuing to move upward. At this time, the annular inclined surface of the pressing sleeve 13 can fit tightly against the inclined surface 123 of each buckle 1221, so that the pushing force applied by each buckle 1221 to the pipe 15 can lock the pipe 15 more securely. At the same time, it avoids the pushing force of each buckle 1221 on the pipe 15 being too large due to the locking cover 121 exceeding the range of movement.

[0062] It can be understood that the limiting part 115 in this embodiment of the utility model is a protrusion or step provided on the outer side wall of the connecting member 11, and the specific type is not limited here.

[0063] according to Figure 3 As shown, in some specific embodiments, a sealing sleeve 14 is provided between the outer wall of the pipe 15 and the cavity wall of the connecting cavity 112.

[0064] Specifically, after each clip 1221 is tightly fitted to the outer wall of the pipe 15 so that one end of the pipe 15 can be stably inserted into the connecting cavity 112, in order to prevent the fluid from leaking out at some gaps when the fluid is flowing in each pipe 15, a sealing sleeve 14 is fitted between the outer wall of the pipe 15 and the cavity wall of the connecting cavity 112. Thus, through the elastic deformation of the sealing sleeve 14, it is used to fill the tiny gaps between the pipe 15 and the connecting cavity 112, forming a strong sealing performance.

[0065] according to Figure 4 As shown, in some specific embodiments, the connecting cavity 112 is recessed with a positioning cavity 1121, which is connected to the communication port 113; one end of the pipeline 15 extends into the positioning cavity 1121.

[0066] Specifically, by extending one end of the pipe 15 into the connecting cavity 112 and finally into the positioning cavity 1121, the outer wall of the pipe 15 fits against the cavity wall of the positioning cavity 1121. This arrangement ensures that the pipe 15 can be accurately inserted into the designated position in the connecting cavity 112, avoiding misalignment of the pipe 15 due to improper installation, which would make it difficult for the through hole at one end of the pipe 15 to be accurately connected to the connecting port 113.

[0067] according to Figure 4 As shown, in some specific embodiments, the cavity wall of the connecting cavity 112 is formed with a guide slope 114 for guiding the movement of the pressing sleeve 13, and the outer side wall of the pressing sleeve 13 is formed with a slope for engaging with the guide slope 114.

[0068] Specifically, since the pressing sleeve 13 can be removed from the connecting cavity 112, in order to assemble the disassembled pressing sleeve 13 into the designated position in the connecting cavity 112, it is only necessary to first put the pressing sleeve 13 on the outer wall of the clamping part 122 (the inclined surface 123 of each buckle 1221 is in contact with the annular inclined surface of the pressing sleeve 13). When one end of the pipeline 15 passes through the locking cavity 124 and extends into the connecting cavity 112, the outer side of the pressing sleeve 13 can be pushed to fit against the guide inclined surface 114 through the clamping part 122. Under the guidance of the guide inclined surface 114, the pressing sleeve 13 moves to the designated position in the connecting cavity 112 and is clamped between the cavity wall of the connecting cavity 112 and the outer wall of the clamping part 122.

[0069] In the above embodiment, the pressing sleeve 13 is a soft rubber sleeve. As such, when the soft rubber sleeve is squeezed, it can generate a pushing force on each buckle 1221 of the clamping part 122, so that each buckle 1221 can stably fit against the outer wall of the pipe 15, thereby locking the pipe 15.

[0070] It is understood that the soft rubber sleeve of this utility model embodiment is made of elastic material, such as silicone or rubber. Such soft rubber sleeve has good elasticity and plasticity. Therefore, when the soft rubber sleeve is squeezed, its material will deform, thereby generating a force for pushing each buckle 1221.

[0071] according to Figures 1-3 As shown, in some specific embodiments, the outer wall of the connecting member 11 is provided with a plurality of driving parts 116 for assisting in pushing the locking cover 121 to rotate circumferentially. For example, when the user pushes each driving part 116, the entire locking cover 121 rotates circumferentially and moves up or down.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model 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 this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
