Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a pipeline connector with a reinforced metal sleeve and a pipeline that is safely detachable. Background Art

[0002] A pipe connector is a device used to connect pipes. Its main function is to connect two or more pipes together to achieve fluid transmission or control. There are many types of pipe connectors, common ones include flanges, threaded joints, clamps, flange joints, welded joints, etc. They can be used to connect pipes of different types, diameters or materials. Usually, the appropriate connector is selected according to the specific pipe system requirements and application scenarios. Pipe connectors are widely used in industry, construction, agriculture and other fields, and are an indispensable and important part of the pipe system.

[0003] In the prior art, pipe connectors mostly use ordinary sleeves to fix components such as outer ring covers and inner ring covers to the connector housing. During long-term pressure-bearing, the sleeve ends may deform, which will cause the outer ring covers, inner ring covers and other components to detach from the connector housing, causing leakage and other problems at the connection. In addition, pipe connectors mostly use claw rings to fix the pipes inserted into the connection ports. If the claw rings can rotate freely, it is easy for the pipes to be unable to be removed from the claw rings, resulting in the inability to remove the pipes. If the claw rings cannot rotate freely, it is easy for the pipes to rotate accidentally, and the pipes may spiral out of the claw rings, causing failure of the connection between the pipe connector and the pipe. Utility Model Content

[0004] In view of the above technical deficiencies, the utility model provides a pipeline connector with a reinforced metal sleeve and a safe and detachable pipeline, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0006] A pipe connector with a reinforced metal sleeve and a safely detachable pipe, comprising: a connector shell, a metal sleeve and a limit piece, the connector shell being provided with at least one connection port for an external pipe, the ends of the connection port being matched with an inner ring cover, a claw ring and an outer ring cover in sequence from the inside to the outside, the metal sleeve being sleeved on the outer ring cover, the inner ring cover and the outer wall of the connector shell, the end of the metal sleeve close to the outer ring cover being provided with a closing end with a stepped cross-section, one end of the outer ring cover being provided with a biting portion that is bitten by the closing end to achieve a tight connection between the outer ring cover and the metal sleeve, a second limit groove being provided between two adjacent claws of the claw ring, the inner wall of the outer ring cover being evenly provided with at least two first limit grooves, the conical inner wall of the inner ring cover being evenly provided with at least two grooves aligned with the first limit grooves, and after the pipe drives the claw ring to rotate a certain angle, at least one second limit groove is respectively aligned with the first limit groove and the groove.

[0007] Furthermore, at least two first clamping blocks are evenly arranged at the end of the connecting port, at least two first clamping grooves cooperating with the first clamping blocks are evenly arranged at one end of the inner ring cover close to the connecting port, at least two second clamping blocks are evenly arranged at one end of the outer ring cover close to the inner ring cover, and at least two second clamping grooves cooperating with the second clamping blocks are evenly arranged on the radial surface of the inner ring cover.

[0008] Furthermore, the second limiting groove, which is respectively aligned with the first limiting groove and the groove, also cooperates with one of the limiting ends of the limiting member, and the limiting end passes through the second limiting groove and abuts against the wall surface of the groove.

[0009] Furthermore, the claws are evenly arranged on the inner wall of the claw ring, and the claws are in a "T" shape.

[0010] Furthermore, the end of the claw close to the center of the claw ring is an arc-shaped sheet.

[0011] Furthermore, a clearance gap is provided between the conical inner wall of the inner ring cover and the clamping claws for the clamping claws to be compressed and moved outwards.

[0012] Furthermore, the inner wall of the connection port is provided with a circle of connection grooves connected to the end surface thereof, and a sealing ring is provided in the connection groove.

[0013] Furthermore, both ends of the connector housing are provided with connection ports for externally connected pipes, and the two connection ports have the same structure.

[0014] The beneficial effects of the utility model are:

[0015] 1. In the present pipe connector, the metal sleeve is sleeved on the outer wall of the outer ring cover, the inner ring cover and the connector housing, and the bite portion at one end of the outer ring cover is bitten by the stepped closing portion of the metal sleeve, thereby reducing the possibility of creep of the end of the metal sleeve due to long-term pressure, and can improve the connection firmness between the metal sleeve, the outer ring cover, the inner ring cover and the connector housing, and improve the overall pressure bearing capacity of the pipe connector to ensure the normal operation of the pipeline system.

[0016] 2. In the pipe connector, the claw ring can rotate flexibly, and the external pipe can also rotate synchronously and flexibly with the claw ring. Therefore, the external pipe will not be mistakenly disassembled due to accidental rotation, and the connection effect is safe and reliable.

[0017] 3. In this pipe connector, after the external pipe drives the claw ring to rotate a certain angle, at least one second limit groove is aligned with the first limit groove and the groove respectively, ensuring that the limit member can pass through the first limit groove and the second limit groove in time and reach the groove, and play its function of limiting the rotation of the claw ring when disassembly is required.

[0018] 4. When disassembly is required, insert a slender limiting piece with a certain strength from the first limiting groove, and limit the rotation of the claw ring through the limiting end of the limiting piece. The user continues to rotate the external pipe while pulling it out. The claws that are restricted from rotation will form a spiral tapping effect on the external pipe, so that the external pipe can be quickly removed in a spiral manner, ensuring that the pipe can be effectively disassembled.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The utility model provides Figures 1 to 15In combination with the detachable pipe connector with a reinforced metal sleeve 2 shown, it includes: a connector housing 1, a metal sleeve 2 and a stopper 16, the connector housing 1 is provided with at least one connection port 3 for an external pipe, the end of the connection port 3 is matched with an inner ring cover 4, a claw ring 6 and an outer ring cover 5 in sequence from the inside to the outside, the metal sleeve 2 is sleeved on the outer ring cover 5, the inner ring cover 4 and the outer wall of the connector housing 1, the end of the metal sleeve 2 close to the outer ring cover 5 is provided with a closing end 21 with a stepped cross-section, the outer One end of the ring cover 5 is provided with a biting portion 22 which is bitten by the closing mouth 21 to achieve a tight connection between the outer ring cover 5 and the metal sleeve 2. A second limiting groove 8 is provided between two adjacent claws 7 of the claw ring 6. The inner wall of the outer ring cover 5 is evenly provided with at least two first limiting grooves 9. The conical inner wall 10 of the inner ring cover 4 is evenly provided with at least two grooves 11 aligned with the first limiting grooves 9. After the pipeline drives the claw ring 6 to rotate a certain angle, at least one second limiting groove 8 is aligned with the first limiting groove 9 and the groove 11 respectively.

[0037] Among them, the metal sleeve 2 is sleeved on the outer wall of the outer ring cover 5, the inner ring cover 4 and the connector housing 1, and the biting portion 22 at one end of the outer ring cover 5 is bitten by the stepped closing portion 21 of the metal sleeve 2, thereby improving the connection firmness between the metal sleeve 2, the outer ring cover 5, the inner ring cover 4 and the connector housing 1, and preventing the metal sleeve 2, the outer ring cover 5 and the inner ring cover 4 from falling off from the connector housing 1, so as to ensure the normal operation of the pipeline system; the claw ring 6 can rotate flexibly, and the external pipeline can also rotate synchronously and flexibly with the claw ring 6, thereby, the external pipeline will not be accidentally disassembled due to accidental rotation, and the connection effect is safe and reliable.

[0038] In addition, the inner wall of the outer ring cover 5 is evenly provided with four first limiting grooves 9, and the conical inner wall 10 of the inner ring cover 4 is evenly provided with four grooves 11 aligned with the first limiting grooves 9; when installing the pipeline, the pipeline can be directly inserted from the connection port 3, and the inserted pipeline is fixed by the claws 7 of the claw ring 6. When the user needs to remove the pipeline from the connection port 3 of the pipeline connector, the pipeline is first rotated a certain angle. Since the claws 7 of the claw ring 6 are in close contact with the outer wall of the pipeline, the claw ring 6 will rotate a certain angle synchronously with the pipeline. After rotating a certain angle At least one second limiting groove 8 is aligned with the first limiting groove 9 and the groove 11 respectively, and then the limiting end 17 of the limiting member 16 is inserted from the first limiting groove 9 of the outer ring cover 5, and the limiting end 17 will pass through the first limiting groove 9 and the second limiting groove 8 in sequence and reach the groove 11 to abut against the wall of the groove 11. At this time, the claw ring 6 will not be able to continue to rotate synchronously with the pipeline due to the restriction of the limiting end 17, so the user can continue to rotate the pipeline to quickly unplug the pipeline from the connection port 3. Using this pipeline connector to connect the pipeline can improve the efficiency of the user's disassembly of the pipeline.

[0039] In an optional embodiment, if Figure 5 , Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown in the combination, at least two first clamping blocks 12 are evenly arranged at the end of the connecting port 3, at least two first clamping grooves 13 cooperating with the first clamping blocks 12 are evenly arranged at one end of the inner ring cover 4 close to the connecting port 3, at least two second clamping blocks 14 are evenly arranged at one end of the outer ring cover 5 close to the inner ring cover 4, and at least two second clamping grooves 15 cooperating with the second clamping blocks 14 are evenly arranged on the radial surface of the inner ring cover 4.

[0040] Among them, two first card grooves 13 cooperating with the first card block 12 are evenly arranged at one end of the inner ring cover 4 close to the connection port 3. During assembly, the first card block 12 is aligned with the first card groove 13 to ensure that the inner ring cover 4 and the connector housing 1 can be quickly and correctly aligned, thereby avoiding the inner ring cover 4 from rotating relative to the connector housing 1 during the assembly process, thereby making the assembly between the inner ring cover 4 and the connector housing 1 easier.

[0041] At the same time, the radial surface of the inner ring cover 4 is evenly provided with two second card grooves 15 that cooperate with the second card block 14. Through the cooperation of the second card block 14 and the second card groove 15, the outer ring cover 5 and the inner ring cover 4 can be firmly connected after alignment, and then the claw ring 6 can be fixed between the inner ring cover 4 and the outer ring cover 5; specifically, the second card block 14 is designed to be matched with the second card groove 15 in shape and size. When assembling, the user only needs to place the outer ring cover 5 on the inner ring cover 4 and ensure that the second card block 14 is correctly inserted into the corresponding second card groove 15, thereby reducing errors in the assembly process of the pipe connector and improving the assembly efficiency of the pipe connector to a certain extent.

[0042] In addition, in standardized production, the design of the second card block 14 and the second card slot 15 can ensure that different outer ring covers 5 and inner ring covers 4 have consistent methods and procedures during assembly. This consistency makes the production line easier to manage and is conducive to the standardized and automated production of pipe connectors.

[0044] Among them, the limiting end 17 of the limiting member 16 is inserted into the second limiting groove 8 which is aligned with the first limiting groove 9 and the groove 11 respectively, and the rotation of the claw ring 6 is limited by the limiting end 17 of the limiting member 16, thereby preventing the claw ring 6 from rotating synchronously with the pipeline. Then the user continues to rotate the external pipeline while pulling it out, and the claw 7 whose rotation is restricted will form a spiral tapping effect on the external pipeline, so that the external pipeline can be quickly removed in a spiral manner, ensuring that the pipeline can be effectively disassembled.

[0045] In addition, the groove 11 can limit the range of movement of the matching portion of the limiting end 17 and the groove 11 within the groove 11, thereby preventing the matching portion of the limiting end 17 and the groove 11 from moving relative to the inner ring cover 4.

[0046] In an optional embodiment, if Fig.13 As shown, the claws 7 are evenly arranged on the inner wall of the claw ring 6, and the claws 7 are in a "T" shape.

[0047] Among them, compared with the ordinary claw 7, the "T"-shaped claw 7 has a larger contact area with the pipeline. Therefore, evenly arranging the "T"-shaped claws 7 on the inner wall of the claw ring 6 can improve the stability of the connection between the claw ring 6 and the pipeline, prevent the pipeline from falling off from the connection port 3, and ensure the normal operation of the pipeline system.

[0048] In an optional embodiment, if Fig.13 and Fig.14 As shown in the figure, the end of the claw 7 close to the center of the claw ring 6 is an arc-shaped sheet.

[0049] Among them, the purpose of setting the claw 7 with a certain curvature is mainly to ensure the tightness and stability of the pipeline connection, so that the claw 7 can better fit the pipeline surface and increase the contact area, thereby improving the stability of the connection; the curvature design also helps to reduce stress concentration during connection, extend the service life of the claw 7 and the claw ring 6, and reduce the possibility of damage or loosening due to stress, thereby ensuring the durability of the connection.

[0050] In an optional embodiment, if Figure 3 and Fig.11 As shown in the figure, a clearance gap 18 is provided between the conical inner wall 10 of the inner ring cover 4 and the claw 7 for the claw 7 to be compressed and moved outward.

[0051] When the inserted pipe is matched with the claw ring 6, the claws 7 of the claw ring 6 will be pressed to move outwards. The clearance 18 is provided to ensure the normal outward movement of the claws 7, thereby ensuring the rapid insertion of the pipe.

[0052] In an optional embodiment, if Figure 3As shown, the inner wall of the connection port 3 is provided with a circle of connection grooves 19 connected to the end surface thereof, and a sealing ring 20 is provided in the connection groove 19 .

[0053] The sealing ring 20 is provided to fill the gap between the connection parts and prevent the leakage of liquid or gas. The sealing ring 20 can also provide certain buffering and vibration absorption functions to make the connection more stable and durable.

[0054] In an optional embodiment, if Figure 1 , Figure 2 and Figure 5 As shown in the figure, both ends of the connector housing 1 are provided with connection ports 3 for externally connecting pipes, and the two connection ports 3 have the same structure.

[0055] The pipe connector is a symmetrical structure, and the connection ports 3 at both ends have the same structure and cooperate with the sealing ring 20, the inner ring cover 4, the claw ring 6, the outer ring cover 5 and the metal sleeve 2 in the same way.

[0056] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
