[0018] The embodiments of the utility model are described in detail below, and the examples of the embodiments are represented in the drawings, wherein the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0019] Embodiment 1

[0020] Reference Figures 1 to 4 , the pipe joint connecting structure described in the embodiment includes pipe 1 and plastic connecting head 3, pipe head 2 is arranged on the outlet end of pipe 1, plastic connecting head 3 is sleeved outside pipe head 2, plastic connecting head 3 and pipe head 2 are fixedly connected by glue, a plurality of flow channel mouths 22 are formed on pipe head 2, the flow channel mouth 22 is communicated with pipe 1, the outlet 31 is installed on plastic connecting head 3, and the outlet 31 is communicated with pipe 1 through flow channel mouth 22 by penetrating plastic connecting head 3.

[0021] Plastic connecting head 3 is used instead of metal die head, equipment cost is reduced, plastic connecting head 3 is sleeved on pipe head 2, and the two are tightly bonded by glue, installation can be completed, according to experimental results, the structure can replace welding of metal parts, so that plastic connecting head 3 and pipe head 2 are connected firmly.

[0022] O-ring 4 is installed at the joint of pipe 1 and plastic connecting head 3, to seal and avoid fluid leakage.

[0023] Preferably, O-ring 4 is installed between the side wall of pipe 1 and plastic connecting head 3, to increase the sealing effect of O-ring 4.

[0024] The outer wall of the smooth pipe head 2 is not conducive to sticking, and therefore the anti-skid strip 21 is arranged on the outer wall of the pipe head 2, and the glue is applied on the anti-skid strip 21, and the anti-skid strip 21 increases the friction to make the sticking between the plastic connector 3 and the pipe head 2 more closely.

[0025] Preferably, the anti-skid strip 21 can be directly polished on the outer wall of the pipe head 2.

[0026] The anti-coming-off groove 32 is arranged on the plastic connector 3, the glue is injected from the anti-coming-off groove 32, the glue extends to between the plastic connector 3 and the pipe head 2, the plastic connector 3 and the pipe head 2 are fixed, the glue forms a glue strip after drying in the anti-coming-off groove 32, when the plastic connector 3 is sleeved on the pipe head 2, the anti-coming-off groove 32 is located outside the anti-skid strip 21, and the anti-coming-off groove 32 can effectively increase the strength of the glue strip and avoid the breaking of the glue strip.

[0027] Preferably, the anti-coming-off groove 32 is arranged on the upper and lower sidewalls of the plastic connector 3 in the height direction, so that the plastic connector 3 is more stable.

[0028] Preferably, the inner wall of the plastic connector 3 is in contact with the outer wall of the pipe head 2. The plastic connector 3 and the pipe head 2 are prevented from forming a large gap, so that the fluid is prevented from remaining in the gap.
