Abstract
Description
Technical Field
[0001] This utility model relates to the field of threaded joints, specifically a special threaded joint that can be repeatedly disassembled and reassembled with an airtight seal. Background Technology
[0002] Gas-tight threaded joints are mechanical components used to connect pipes or tubing strings. They possess excellent sealing performance and connection strength, and are widely used in the petroleum, natural gas, and chemical industries. Below is some key information about gas-tight threaded joints. Through surface treatment techniques, such as copper plating or sandblasting, thread adhesion during use can be effectively prevented, ensuring the reliability and service life of the joint.
[0003] When connecting hoses using a threaded connection, a wrench is generally used for tightening. However, in confined spaces, it is difficult for the wrench to grip the threaded connection. Even if the wrench is gripped, there is not enough space for the wrench to rotate, making it difficult to tighten the threaded connector. Therefore, a special threaded connector with a reusable and airtight seal is proposed to address the above problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model proposes a special threaded joint that can be repeatedly disassembled and reassembled with an airtight seal.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a reusable and detachable air-tight special threaded joint, including a threaded joint, a screwing part is provided in the middle of the threaded joint, and slots are respectively provided on the left and right sides of the screwing part. A moving block is inserted into the slot, a limit plate is fixedly connected to the side of the moving block, a hinge is provided at the end of the moving block, a flap is provided at the end of the hinge, a second locking part is provided on one side of the upper part of the moving block, and a positioning part is provided on the other side of the upper part of the moving block.
[0006] Preferably, the card slot further includes a card hole, which is provided on the upper part of the inner wall of the card slot, and the card hole is engaged with the card position member.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a reusable and reassembleable gas-tight special threaded joint, including a threaded joint 1. The threaded joint 1 has a screwing part 2 in the middle. The screwing part 2 has slots 3 on the left and right sides respectively. A moving block 4 is inserted into the slots 3. A limit plate 5 is fixedly connected to the side of the moving block 4. A hinge 8 is provided at the end of the moving block 4. A flap 6 is provided at the end of the hinge 8. A second locking member 9 is provided on one side of the upper part of the moving block 4. A positioning member 7 is provided on the other side of the upper part of the moving block 4.
[0025] The slot 3 also includes a first slot 31, and the first slot 31 is provided on the upper part of the inner wall of the slot 3. The first slot 31 is engaged with the second slot member 9.
[0026] The second locking component 9 includes: a positioning cylinder 91, a second spring 92, a second bullet head 93, and a lever 931. The end of the second locking component 9 is fixedly connected to the end of the positioning cylinder 91. The inner wall of the positioning cylinder 91 is fixedly connected to one end of the second spring 92. The other end of the second spring 92 is fixedly connected to one end of the lever 931. The other end of the lever 931 is fixedly connected to the end of the second bullet head 93. The rod of the lever 931 is slidably connected to the groove on the side of the positioning cylinder 91.
[0027] The flap 6 also includes a second locking hole 61, and the upper part of the flap 6 has a second locking hole 61, which is engaged with the positioning member 7.
[0028] The positioning component 7 includes: a connecting handle 71 and a locking component 72. The end of the positioning component 7 is fixedly connected to one end of the connecting handle 71, and the other end of the connecting handle 71 is fixedly connected to the end of the locking component 72.
[0029] The locking component 72 further includes: a spring 721 and a bullet head 722. The inner wall of the locking component 72 is fixedly connected to one end of the spring 721, and the other end of the spring 721 is fixedly connected to the end of the bullet head 722.
[0030] Working principle: When aligning the threaded end of the threaded connector 1 with the hose to be connected, the actuating block 4 needs to be inserted into the slot 3 on the side of the screwing part 2. As the actuating block 4 is inserted, the bullet head 93 is squeezed by the inner wall of the slot 3, causing the bullet head 93 to retract into the positioning cylinder 91. The spring 92 is compressed by the bullet head 93. When the bullet head 93 is aligned with the locking hole 31, the spring 92 drives the bullet head 93 to insert into the locking hole 31, thereby fixing the actuating block 4 and preventing the actuating block 4 from being inserted when the screwing part 2 is tilted. Within the groove 3, the sliding of the actuating block 4 is achieved, allowing manual rotation of the actuating block 4 to connect the threaded connector 1 to the hose. When tightening the threaded connector 1 is difficult, the flip plate 6 needs to be flipped. During this process, the rotation of the flip plate 6 causes the bullet head 722 inside the locking hole 61 to retract into the locking part 72. In this process, the spring 721 is compressed by the bullet head 722. When the locking hole 61 is flipped into place, it will be blocked by the limiting plate 5 to prevent the flip plate 6 from over-flipping. Thus, manually actuating the flip plate 6 makes it easier to connect the threaded connector 1 to the hose.
[0031] By engaging the locking block 4 with the slot 3, the threaded connector 1 can be connected to the hose by manually moving the locking block 4. This avoids the problem of the threaded connector 1 being difficult to connect to the hose due to space limitations when using a wrench to tighten the connector 2. The flap 6 extends the length of the locking block 4 by moving the flap 6, allowing the screwing part 2 to be rotated by manually moving the flap 6. When the screwing part 2 is difficult to tighten, the extended flap 6 can easily drive the screwing part 2 to rotate, thus connecting the threaded connector 1 to the hose.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
