The outer side of the lower end of the pipe joint 1 is provided with a clamping pin groove matched with the clamping pin 2 in diameter, and the clamping pin groove is an outer ring groove. The inner side of the upper end of the shell 4 is provided with a bayonet lock hole matched with the diameter of the bayonet lock 2, and the bayonet lock hole is provided with two through holes for allowing the bayonet lock 2 to pass through.
Wherein, the pipe joint 1 is provided with a sealing groove for placing the sealing element 3 below the clamping pin groove.
The side surface of the outer cylinder of the pipe joint 1 is provided with a step, the step is positioned between the clamping pin groove and the sealing groove, and the diameter of the cylinder below the step is smaller than that of the cylinder above the step.
Wherein, in order to be convenient for seal 3 on coupling 1 smoothly pack into in the casing 4, casing 4 sets up the step hole, and step hole below cylinder diameter is less than top cylinder diameter, can make seal 3 avoid contacting the sharp limit of the bayonet hole of casing 4 and producing the damage in the assembly process.
The bayonet lock 2 is U-shaped, and after installation, the two ends of the bayonet lock 2 are bent and deformed to play a role in preventing looseness.
The utility model has the advantages that:
The rotatable hydraulic pipe joint structure is simple and reliable in structure, and can rotate the direction of the pipe joint by 360 degrees around the center line of the mounting hole, so that the requirement of rotation of the pipe joint is met.

Detailed Description
The utility model is described in further detail below with reference to specific embodiments and figures.
As shown in fig. 1 and 2, an embodiment of the present utility model provides a hydraulic pipe joint, which includes a pipe joint 1 and a housing 4, wherein the outer side of the lower end of the pipe joint 1 is connected with the inner side of the upper end of the housing 4 by a bayonet 2.
The pipe joint 1 is of a 90-degree bent pipe structure, the upper end of the pipe joint 1 can be designed into a 24-degree non-flaring structure according to HB 5970, a 24-degree non-flaring structure is shown in fig. 1, or a 74-degree flaring structure according to HB 4-3, and the pipe joint is connected with an external hydraulic pipeline. The pipe joint 1 can rotate 360 degrees around the center line of the shell 4, and the function of the rotatable hydraulic pipe joint is realized.
As shown in fig. 1, another embodiment of the present utility model further provides a hydraulic pipe joint, further including: and the sealing element 3 is positioned at the contact position of the pipe joint 1 and the shell 4 and below the clamping pin 2, and the sealing element 3 can realize the hydraulic sealing effect between the pipe joint 1 and the shell 4. Here, the sealing element 3 may be an O-ring or an O-ring plus a protection ring, depending on the hydraulic system pressure.
In one embodiment, the outer side of the lower end of the pipe joint 1 is provided with a bayonet slot matched with the diameter of the bayonet 2, and the bayonet slot is an outer ring slot. The inner side of the upper end of the shell 4 is provided with a bayonet lock hole matched with the diameter of the bayonet lock 2, and the bayonet lock hole is provided with two through holes for allowing the bayonet lock 2 to pass through. The positions of the detent grooves on the pipe joint 1 are matched with the positions of the detent holes on the shell 4.
Further, a sealing groove for placing the sealing element 3 is arranged below the clamping pin groove on the pipe joint 1.
The side of the outer cylinder of the pipe joint 1 is provided with a step, the step is positioned between the clamping pin groove and the sealing groove, the roughness of the cylinder surface below the step is required to be Ra0.8μm, and the diameter of the cylinder below the step is smaller than that of the cylinder above the step.
In an embodiment, in order to facilitate the smooth installation of the sealing member 3 on the pipe joint 1 into the housing 4, a stepped hole is provided in the housing 4, the roughness of the cylinder surface of the step Kong Xia is required to be ra0.8 μm, and the diameter of the cylinder below the stepped hole is smaller than that of the cylinder above, so that the sealing member 3 can be prevented from being damaged due to contact with the sharp edge of the bayonet hole of the housing 4 in the assembly process.
