Description

Technical Field

[0001] This utility model belongs to the field of pipe fittings, specifically relating to a compression fitting type direct connector. Background Technology

[0002] Compression fittings mainly consist of three parts: the fitting body, the ferrule, and the nut. Compression fittings are characterized by reliable connection, high pressure resistance, good temperature resistance, good sealing and repeatability, convenient installation and maintenance, and safe and reliable operation.

[0003] Because pipelines generate vibrations during medium transport, these vibrations can cause the nuts on compression fittings to rotate backwards, resulting in gaps between the fitting body, the compression fitting, and the nut, leading to medium leakage. Existing reinforcement structures mostly use bolt-type structures, which require a significant amount of time to tighten each bolt in actual use, reducing assembly efficiency. Therefore, a compression fitting type is proposed to address these issues. Utility Model Content

[0007] A compression fitting, placed between the connecting nut and the connector body, is used to compress and secure external pipes.

[0008] Two connectors are positioned diagonally on the outer wall of the connecting nut;

[0009] The fastener is installed on the joint body and plugged into the two connectors to reinforce the connection between the joint body and the column base.

[0010] Furthermore, the connector includes a sleeve mounted on the connecting nut; an insert plate slidably inserted into the sleeve at one end; and two ratchet plates mounted on either side of the insert plate.

[0011] Furthermore, the sleeve has a T-slot inside, and one end of the insert plate is designed in a T-shape and is adapted to the T-slot to limit the maximum movement position of the insert plate.

[0012] Furthermore, the fastener includes an annular slide rail fitted onto the connector body; two slides slidably mounted on the annular slide rail; two insert rods respectively mounted on the front and rear sides of the slides, the two insert rods slidingly penetrating the slides, one end of the insert rod inside the slide being provided with a second ratchet plate and the other end being provided with a stop block; a spring disposed between the stop block and the slides; the second ratchet plate meshes with the first ratchet plate for fixing the insert plate and the connecting nut.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0023] Please see Figure 1-6 In this embodiment, the ferrule-type direct connector, compared to the bolt-type design of the existing reinforcement structure, only requires simple insertion during use. In mass assembly, there is no need to spend a lot of time tightening bolts, thereby improving the assembly efficiency and ease of use of the direct connector.

[0024] Specifically, it includes a hollow connector body 1, and the connector body 1 has a column base 2 inside;

[0025] The connecting nut 3 has a thread on the left end of the connector body 1, and both the connector body 1 and the inner wall of the connecting nut 3 have a tapered surface.

[0026] The ferrule 4 is positioned between the connecting nut 3 and the connector body 1 and is used to compress and fix the external pipe.

[0027] Two connectors 5 are arranged diagonally on the outer wall of the connecting nut 3;

[0028] The fastener 6 is installed on the connector body 1 and plugged into the two plug-in parts 5 to reinforce the connection between the connector body 1 and the column base 2.

[0029] In this embodiment, during use, one end of the pipe needs to be inserted into the hollow space between the connector body 1 and the connecting nut 3. After the ferrule 4 and the connecting nut 3 are inserted into the connector body 1, when the nut is tightened, the squeezing force of the connecting nut 3 on the ferrule 4 when tightened with the connector body 1 causes the outer front end of the ferrule 4 to come into contact with the conical surface of the connector body 1 and gradually deform. Finally, the inner edge of the ferrule 4 evenly bites onto the pipe and forms an effective seal, thereby completing the connection with the external pipe. Subsequently, the two plug-in parts 5 can be inserted into the fixing part 6. The connection formed by the fixing part 6 can strengthen the connecting nut 3 and prevent the connecting nut 3 from reversing and causing medium leakage. Compared with the existing reinforcement structure that uses a bolt design, this solution only requires simple insertion during use. In mass assembly, there is no need to spend a lot of time tightening bolts, thereby improving the assembly efficiency and ease of use of the direct connector.

[0030] Specifically, refer to Figure 2-4 The connector 5 includes a sleeve 51 mounted on the connecting nut 3; a plate 52 slidably inserted into the sleeve 51 at one end; and two ratchet plates 53 mounted on both sides of the plate 52.

[0031] Specifically, refer to Figure 4 The sleeve 51 has a T-slot 7 inside, and one end of the insert plate 52 is T-shaped and adapted to the T-slot 7 to limit the maximum movement position of the insert plate 52.

[0032] Specifically, refer to Figure 2-5 The fixing component 6 includes an annular slide rail 61 sleeved on the connector body 1; two slides 62 slidably mounted on the annular slide rail 61; two insert rods 63 respectively mounted on the front and rear sides of the slides 62, the two insert rods 63 slidably passing through the slides 62, one end of the insert rod 63 inside the slides 62 is provided with a second ratchet plate 64 and the other end is provided with a stop block 65; a spring 66 is provided between the stop block 65 and the slides 62; the second ratchet plate 64 meshes with the first ratchet plate 53 and is used to fix the insert plate 52 and the connecting nut 3.

[0033] In this embodiment, when it is necessary to reinforce the connecting nut 3, the two slides 62 can be pulled to slide on the annular slide rail 61 and adjusted to be opposite to the two sleeves 51. Then, the insert plate 52 can be inserted into the slide 62 after passing through the sleeve 51. During this process, the spring force of the spring 66 can push the insert rod 63 and the stop block 65 to move back and forth, and the ratchet plate 64 and the ratchet plate 53 can reciprocate to fix the insert plate 52. The T-shaped head end of the insert plate 52 can be matched with the T-shaped groove 7 to limit the maximum movement position of the insert plate 52. When the insert plate 52 moves to the maximum position, the connector body 1 and the connecting nut 3 can be pulled to keep them tightly attached, and the movement direction of the two can be limited, thereby preventing loosening between them. Compared with the existing reinforcement structure that uses a bolt design, this solution only requires simple insertion during use. In mass assembly, there is no need to spend a lot of time tightening bolts, thereby improving the assembly efficiency and ease of use of the direct head.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
