This fitting fixes the pipe in the fitting through the crimping process, ensuring the sealing and reliability of the connection.

[0003] However, in the prior art, the sleeve size of the traditional crimped hydraulic pipe joint is fixed, which is not convenient to adjust according to the size of the hydraulic pipe. Therefore, the sleeve and the joint are prone to loosening after being connected to the hydraulic pipe, resulting in a loose connection between the joint and the hydraulic pipe. Moreover, when the connecting nut at one end of the joint is connected to other hydraulic pipes through threads, it is easy to become loose or rotate, thereby loosening the connecting nut. Utility Model Content

[0018] The technical effect of adopting the above further solution is that the elastic piece is connected to the limit block and the positioning plate.

[0019] Preferably, a sealing ring is fixedly provided at the connection between the annular plate and the joint body.

[0020] The technical effect of adopting the above further solution is that the sealing ring can improve the sealing performance and prevent leakage from occurring at the connection between the joint body and the hydraulic pipe.

[0022] 1. In the present invention, the joint body is embedded in the interior of the hydraulic pipe, and two arc-shaped clamping plates are sleeved on the outer surface of the hydraulic pipe. The rotating adjustment screw can drive the two arc-shaped clamping plates to clamp the hydraulic pipe through the T-shaped block. The T-shaped block moves relative to or away from each other inside the T-shaped groove, which can drive the arc-shaped clamping plates to adjust according to the size of the hydraulic pipe, making the joint body more securely installed. The sealing ring fixed at one end of the joint body can improve the sealing performance and prevent leakage at the connection between the joint body and the hydraulic pipe.

[0023] 2. In the utility model, the connecting nut is rotated to connect it with another hydraulic pipe. The bottom of the connecting nut is fixedly installed with a limit block through a connecting rod. A slide groove is provided on the outer surface of the limit block. The pawl is movably embedded in the inside of the slide groove and embedded in the inside of the ratchet groove under the elastic force of two elastic sheets. The connecting nut can be connected to the hydraulic pipe by forward rotation. The pawl slides along the tooth shape of the ratchet groove, allowing the pawl to retract freely. The pawl is blocked by the tooth shape of the ratchet groove when it is rotated in the reverse direction, so that the pawl cannot retract. The connecting nut can only be rotated by pulling the pawl out of the inside of the ratchet groove through the positioning plate. This can prevent the connecting nut from rotating loose, thereby improving the connectivity. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the joint body 1 is embedded in the interior of the hydraulic pipe, and the two arc-shaped clamping plates 108 are sleeved on the outer surface of the hydraulic pipe. The rotating adjustment screw 109 can drive the two arc-shaped clamping plates 108 to clamp the hydraulic pipe through the T-shaped block 117. The T-shaped block 117 moves relative to or away from each other inside the T-shaped groove 110, which can drive the arc-shaped clamping plates 108 to adjust according to the size of the hydraulic pipe, so that the joint body 1 is installed more stably. The sealing ring 113 fixedly installed at one end of the joint body 1 can improve the sealing performance and prevent leakage at the connection between the joint body 1 and the hydraulic pipe.

[0036] Working principle: When in use, the joint body 1 is embedded in the interior of the hydraulic pipe, and the two arc-shaped clamping plates 108 are sleeved on the outer surface of the hydraulic pipe. The rotating adjusting screw 109 can drive the two arc-shaped clamping plates 108 to clamp the hydraulic pipe through the T-shaped block 117. The T-shaped block 117 moves relative to or opposite to each other inside the T-shaped groove 110, which can drive the arc-shaped clamping plates 108 to adjust according to the size of the hydraulic pipe, so that the joint body 1 is installed more firmly. The sealing ring 113 fixedly installed at one end of the joint body 1 can improve the sealing and prevent leakage at the connection between the joint body 1 and the hydraulic pipe. A connecting pipe 104 is fixedly installed at one end of the joint body 1, and a connecting nut 103 is movably sleeved on the outer surface of the connecting pipe 104. The connecting nut 103 is rotated to connect it with the other The hydraulic pipe is connected, and the bottom of the connecting nut 103 is fixedly installed with a limit block 111 through a connecting rod 105.

The pawl 115 slides along the tooth shape of the ratchet groove 102, so that the pawl 115 can retract freely. When the pawl 115 is rotated in the reverse direction, it is blocked by the tooth shape of the ratchet groove 102, so that the pawl 115 cannot retract. Only by pulling the pawl 115 out of the inside of the ratchet groove 102 through the positioning plate 106 can the connecting nut 103 be rotated, which can prevent the connecting nut 103 from rotating loose and improve the connectivity.
