Description

Technical Field

[0001] This utility model belongs to the field of semiconductor pipe connection technology, and specifically relates to a pipe connector structure. Background Technology

[0002] Semiconductor pipelines are special pipeline systems used in semiconductor manufacturing to transport high-purity gases, ultrapure water, and corrosive chemicals. They are the "vascular network" of chip manufacturing and are directly related to product yield and process stability.

[0003] In related technologies, the pipe fittings widely used in the semiconductor industry currently employ threaded connections during installation and use. Although threaded connections offer advantages such as easy assembly and compact structure, during long-term operation, the threaded parts are prone to corrosion and jamming due to factors such as environmental humidity, chemical media, or temperature changes. This not only affects the airtightness and stability of the connection but also brings many difficulties during subsequent maintenance, replacement, or disassembly. In practice, maintenance personnel often need to use special tools or apply significant external force to disassemble the pipes, which not only increases maintenance time and labor costs but may also damage the fittings and adjacent pipelines, thereby affecting the overall reliability and service life of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe connector structure. Its advantage is that during long-term operation, due to the influence of factors such as environmental humidity, chemical media or temperature changes, the threaded parts are prone to corrosion and jamming. This not only affects the airtightness and stability of the connection, but also brings many difficulties to subsequent maintenance, replacement or disassembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe connector structure, including a semiconductor pipe connector, wherein pipes are provided on both sides of the semiconductor pipe connector, and metal rings are fixedly connected to both sides of the surface of the semiconductor pipe connector, and a snap-fit ​​component is provided on the outer side of the metal rings. The snap-fit ​​assembly includes a blocking ring located outside the semiconductor pipe connector. A fixing frame is fixedly connected to the surface of the semiconductor pipe connector, a locking rod is slidably connected to the surface of the fixing frame, and a ring is fixedly connected to the surface of the locking rod. The blocking ring is slidably connected to the locking rod, and a locking groove is formed on the surface of the pipe to engage with the locking rod. A limiting rod is fixedly connected to the outside of the metal ring, and the limiting rod is slidably connected to the blocking ring. A support spring is sleeved on the surface of the limiting rod.

[0006] The present invention is further configured to include an operating component, the operating component including a movable ring located on the surface of the semiconductor pipe connecting tube, the movable ring being located inside the metal ring, a sliding rod fixedly connected to the outer side of the movable ring, the outer side of the sliding rod being fixedly connected to the surface of the blocking ring, and the sliding rod being slidably connected to the metal ring.

[0007] The above technical solution involves setting up an operating component that uses a moving ring to drive a sliding rod, which in turn drives a blocking ring to move synchronously. The sliding cooperation between the sliding rod and the metal ring ensures smooth operation. The engagement and disengagement of the snap-fit ​​component can be controlled without the need for additional tools, significantly simplifying the installation and disassembly process of the pipeline and improving the ease of use and operational efficiency of the connectors.

[0008] The present invention is further configured such that a small spring is fixedly connected to the inner side of the ring, and the inner side of the small spring is fixedly connected to the surface of the fixing frame.

[0009] The above technical solution utilizes a small spring to provide a continuous elastic force to the locking lever, which not only enhances the tightness of the locking lever and the locking slot, preventing gaps that could lead to unstable connections, but also assists the locking lever in quick resetting during disassembly, making subsequent operations smoother and further improving the stability and practicality of the connector.

[0010] The present invention is further configured such that an operating block is fixedly connected to both the top and bottom of the moving ring, and the number of the operating blocks is several.

[0011] By adopting the above technical solution, the setting of the operating block increases the contact friction and force area between the hand and the moving ring, allowing the user to easily apply force to push the moving ring, effectively avoiding slippage during operation, making the control of the locking component more effortless and precise, and improving the overall convenience of operation and user experience.

[0012] The present invention is further configured such that sealing rings are fixedly connected to both sides of the inner wall of the semiconductor pipe connecting tube, and the number of sealing rings is several.

[0013] The above technical solution, with its multiple sealing rings, can tightly fit the gap between the outer wall of the pipe and the inner wall of the semiconductor pipe connector, forming multiple layers of sealing protection. This effectively prevents fluid leakage from the pipe, improves the sealing performance of the connector, and ensures safety and reliability during use. It is suitable for various fluid transportation scenarios.

[0014] The present invention is further configured such that the number of the supporting springs is several, and the supporting springs are evenly distributed in a ring.

[0015] The above technical solution employs multiple support springs, which provide balanced and continuous elastic support to the blocking ring, ensuring that the force on each locking rod is consistent. This makes the locking of the locking rod and the locking groove more uniform and stable, avoiding connection failure or pipe displacement caused by uneven local force, and extending the service life of the connector.

[0016] The present invention is further configured such that all the fixing brackets are located inside the blocking ring, and the number of fixing brackets is several.

[0017] The above technical solution adopts a layout design in which the fixing bracket is located inside the blocking ring, which not only avoids interference with other parts of the snap-fit ​​assembly and the operating components, but also provides a stable installation and sliding support point for the snap-fit ​​rod. The setting of several fixing brackets further improves the overall structural strength of the snap-fit ​​assembly, ensures the stability and reliability of the snap-fit ​​action, and enhances the structural durability of the connector.

[0018] The present invention is further configured such that the number of card slots is several, and the number of card slots is the same as the number of card rods.

[0019] By adopting the above technical solution, the design of keeping the number of slots and clamps consistent enables multi-point synchronous clamping between the pipe and the semiconductor pipe connection tube. Compared with a single clamping point, multi-point clamping can distribute the force, significantly improve the connection firmness, effectively avoid the overall connection loosening caused by damage or failure of a single clamping point, and further enhance the stability and reliability of the connector structure.

[0020] In summary, this utility model has the following beneficial effects: 1. This utility model utilizes a linkage design where a moving ring drives a sliding rod to drive a blocking ring. This design allows for control of the engagement and disengagement of the snap-fit ​​components without the need for additional tools, significantly simplifying the pipe installation and disassembly process and greatly improving operational efficiency. Furthermore, the multi-point synchronous snap-fit ​​design, with an equal number of slots and rods, coupled with evenly distributed ring-shaped support springs, ensures balanced force distribution on each rod. This disperses the connection stress, prevents overall loosening due to failure at a single snap-fit ​​point, and ensures uniform and stable engagement. This fundamentally improves the reliability of the connection between the pipe and the semiconductor pipe, meeting the core requirements of efficient assembly and stable use.

[0021] 2. This utility model increases the contact friction and force-bearing area between the hand and the moving ring by setting the operating block, avoiding slippage during operation and making the application of force more effortless and precise. The small spring provides continuous elastic force to the locking rod, which not only enhances the tightness of the locking rod and the locking groove and eliminates the risk of gaps, but also assists the locking rod to quickly reset, ensuring smooth subsequent operation. The multiple sealing rings form a multi-layer sealing protection, which effectively prevents fluid leakage and improves sealing performance and safety of use. The layout design of the fixing bracket located inside the blocking ring avoids interference with other components and provides stable support for the locking rod. At the same time, the setting of several fixing brackets enhances the structural strength of the locking assembly. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1: refer to Figures 1-4 A pipe connector structure includes a semiconductor pipe connector 1, with pipes 2 on both sides of the semiconductor pipe connector 1, and metal rings 3 fixedly connected to both sides of the surface of the semiconductor pipe connector 1, with snap-fit ​​components 4 on the outer side of the metal rings 3. The snap-fit ​​assembly 4 includes a blocking ring 41 located outside the semiconductor pipe connecting tube 1. A fixing frame 42 is fixedly connected to the surface of the semiconductor pipe connecting tube 1. A locking rod 43 is slidably connected to the surface of the fixing frame 42. A ring 44 is fixedly connected to the surface of the locking rod 43. The blocking ring 41 and the locking rod 43 are slidably connected. A slot 45 for engaging with the locking rod 43 is opened on the surface of the pipe 2. A limiting rod 46 is fixedly connected to the outside of the metal ring 3. The limiting rod 46 is slidably connected to the blocking ring 41. A support spring 47 is sleeved on the surface of the limiting rod 46.

[0026] refer to Figure 4A small spring 6 is fixedly connected to the inner side of the ring 44, and the inner side of the small spring 6 is fixedly connected to the surface of the fixing frame 42. The small spring 6 provides a continuous elastic force to the locking rod 43, which not only enhances the tightness of the locking rod 43 and the locking groove 45, avoiding gaps that could lead to unstable connection, but also helps the locking rod 43 to quickly reset during disassembly, making subsequent operations smoother and further improving the stability and practicality of the connector.

[0027] refer to Figure 3 Both sides of the inner wall of the semiconductor pipe connector 1 are fixedly connected with sealing rings 8, and there are several sealing rings 8. The setting of multiple sealing rings 8 can tightly fit the gap between the outer wall of the pipe 2 and the inner wall of the semiconductor pipe connector 1, forming multiple sealing protection, effectively preventing the leakage of fluid in the pipe 2, improving the sealing performance of the connector, ensuring safety and reliability during use, and is suitable for various fluid transportation scenarios.

[0028] refer to Figure 4 There are several support springs 47, which are evenly distributed in a ring. The multiple support springs 47 can provide a balanced and continuous elastic support force for the blocking ring 41, ensuring that the force on each clamp 43 is consistent, making the clamping of the clamp 43 and the clamping groove 45 more uniform and stable, avoiding connection failure or pipe 2 displacement caused by uneven local force, and extending the service life of the connector.

[0029] refer to Figure 4 The fixing brackets 42 are all located inside the blocking ring 41, and there are several fixing brackets 42. The layout design of the fixing brackets 42 located inside the blocking ring 41 not only avoids interference with other parts of the snap-fit ​​assembly 4 and the operating assembly 5, but also provides a stable installation and sliding support point for the locking rod 43. The setting of several fixing brackets 42 further improves the overall structural strength of the snap-fit ​​assembly 4, ensures the stability and reliability of the snap-fit ​​action, and enhances the structural durability of the connector.

[0030] refer to Figure 2 The number of slots 45 is several, and the number of slots 45 is the same as the number of levers 43. The design that the number of slots 45 and levers 43 is consistent enables multi-point synchronous engagement between pipe 2 and semiconductor pipe connecting pipe 1. Compared with a single engagement point, multi-point engagement can distribute the force, significantly improve the connection firmness, effectively avoid the overall connection loosening caused by damage or failure of a single engagement point, and further enhance the stability and reliability of the connector structure.

[0031] Brief description of the usage process: First, the moving ring 51 is pushed by several operating blocks 7 at the top and bottom. The moving ring 51 slides along the surface of the semiconductor pipe connecting tube 1 and drives the outer fixed slide rod 52 to move synchronously. After the slide rod 52 passes through the metal ring 3, it drives the outer blocking ring 41 to slide along the limiting rod 46 fixed to the metal ring 3. At this time, the support spring 47 sleeved on the limiting rod 46 is compressed. After the blocking ring 41 moves, it releases the clamping effect on the locking rod 43. The small spring 6 connected to the inner side of the circular ring 44 on the surface of the locking rod 43 releases the elastic force, pushing the locking rod 43 to slide outward along several fixing brackets 42 fixed to the surface of the semiconductor pipe connecting tube 1, reserving space for the insertion of the pipe 2. Then, the pipe 2 is inserted into both sides of the semiconductor pipe connecting tube 1. During the insertion process, several sealing rings 8 on both sides of the inner wall of the semiconductor pipe connecting tube 1 are tightly fitted with the outer wall of the pipe 2, forming a seal. Multiple sealing rings are used to prevent fluid leakage. After the pipe 2 is inserted into place, the operating block 7 is released, the support spring 47 resets and pushes the blocking ring 41 back along the limiting rod 46. The back-moving blocking ring 41 squeezes the locking rod 43, causing the locking rod 43 to overcome part of the elastic force of the small spring 6 and slide inward along the fixing frame 42 until the locking rod 43 is accurately locked into the several slots 45 opened on the surface of the pipe 2. At this time, the small spring 6 continues to provide elastic force to the locking rod 43, ensuring that the locking rod 43 and the slot 45 are tightly locked without gaps. The fixing frame 42 provides stable support for the locking rod 43, ensuring that the locking structure is stable. During use, the evenly distributed ring-shaped support spring 47 provides balanced elastic support force to the blocking ring 41, so that each locking rod 43 is subjected to the same force, avoiding pipe 2 displacement or connection failure due to uneven local force. The multiple sealing rings 8 continuously maintain the sealing performance to prevent fluid leakage.

[0032] Example 2: refer to Figures 1-4 A pipe connector structure further includes an operating component 5. The operating component 5 includes a movable ring 51 located on the surface of the semiconductor pipe connector 1 and inside the metal ring 3. A slide rod 52 is fixedly connected to the outer side of the movable ring 51 and to the surface of a blocking ring 41. The slide rod 52 is slidably connected to the metal ring 3. The operating component 5 is configured such that the movable ring 51 drives the slide rod 52 to move, thereby driving the blocking ring 41 to move synchronously. The sliding cooperation between the slide rod 52 and the metal ring 3 ensures the smoothness of the operation process. The locking and disengaging of the locking component 4 can be controlled without the need for additional tools, which significantly simplifies the installation and disassembly process of the pipe 2 and improves the ease of use and operating efficiency of the connector.

[0033] refer to Figure 2The top and bottom of the moving ring 51 are fixedly connected with operating blocks 7, and there are several operating blocks 7. The setting of operating blocks 7 increases the contact friction and force area between the hand and the moving ring 51, allowing the user to easily apply force to push the moving ring 51, effectively avoiding slippage during operation, making the control of the locking component 4 more effortless and precise, and improving the overall convenience of operation and user experience.

[0034] Brief description of the usage process: When disassembling, push the operating block 7 again to move the moving ring 51, the slide bar 52 and the blocking ring 41, compress the support spring 47, release the blocking ring 41 from the pressure on the locking rod 43, and the small spring 6 assists the locking rod 43 to reset and disengage from the slot 45. At this time, the pipe 2 can be pulled out from both sides of the semiconductor pipe connecting tube 1 to complete the disassembly.

[0035] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
