[0032] Reference Figure 1-4 A multi-size docking automobile oil pipe joint comprises: a joint 1, one end of which is configured with an opening for docking and the other end of which is fixed with a connecting pipe 2 connected to the joint 1; a joint 2 3, which is movably installed on the outside of the joint 1 1 in a horizontal direction; a joint 3 4, which is movably installed on the outside of the joint 2 3 in a horizontal direction. Further, the outside of the joint 1 has but is not limited to the current two joints 2 3 and the joint 3 4, which can be increased or deleted according to actual conditions, so that multi-size docking can be performed under the action of each joint, and a limiting component is installed between the joint 3 4 and the joint 2 3 and between the joint 2 3 and the joint 1, so that the limiting component can guide and limit the activities between the joint 3 4 and the joint 2 3 and between the joint 2 3 and the joint 1, so as to avoid loosening between the movable joints and improve the flexibility of the joints; a clamping component that improves the connection strength and is movable is installed on the surface of the joint 3 4, and the docked pipeline can be further clamped and fixed by the clamping component, so as to avoid loosening of the connection position caused by the large vibration generated after the operation of the automobile, and improve the connection strength.

[0033] Specifically, refer to Figure 1 , Figure 2 and Figure 4The limiting assembly includes: a limiting portion 1 5 and a limiting portion 2 11; the limiting portion 1 5 is arranged on the surface of the joint 1 and the joint 2 3, and the limiting portion 2 11 is installed at one end of the joint 3 4 and the joint 2 3 and extends into the limiting portion 1 5. Through this implementation, each joint can drive the limiting portion 1 5 to slide in the limiting portion 2 11 when it moves, so as to move and adjust the position of each joint, so as to expose the inner joint for docking, and under the action of the limiting assembly, the movement between the joints can be guided and limited to avoid the joints from being separated.

[0034] Specifically, refer to Figure 2-3 The clamping assembly includes: a bracket 7, an elastic member 8, a clamping portion 9 and a fixing hole 10; the brackets 7 are all installed on the surface of the joint three 4, the elastic members 8 are all installed on the end of the bracket 7 away from the joint three 4, the clamping portions 9 are all installed on the end of the elastic member 8 away from the bracket 7, and the fixing holes 10 are all opened through the surface of the clamping portion 9. Through this embodiment, after the joints are docked, the personnel can connect the two clamping portions 9 through the fixing holes 10 and the fastening bolts, and the clamping portion 9 can be elastically moved through the elastic member 8, so that the clamping portion 9 can further stabilize and fix the docking position, thereby avoiding looseness at the joint position and improving the connection strength of the joint.

[0035] Furthermore, the clamping portion 9 is arranged in an arc shape, and the two clamping portions 9 correspond to each other. Through this design, the two clamping portions 9 can better cooperate to fix the pipeline and the joint to avoid deviation, and the arc-shaped clamping portion 9 can better fit the pipeline, thereby increasing the contact area and connection strength.

[0036] Furthermore, the inner sides of connector 1, connector 2, 3 and connector 3, 4 are all constructed with internal threads 6. Through this design, when the pipelines are docked, the internal threads 6 inside the connectors can be matched with the external threads at the connection positions for docking and fixation, which facilitates the connection operation.

[0037] Furthermore, both the inside of joint three 4 and joint two 3 are provided with a sealing ring 12 located at one end of joint two 3 and joint one 1. Through this design, the sealing ring 12 is usually made of elastic material, such as rubber or silicone, which can fit tightly on the contact surface of the two joints to effectively prevent the leakage of liquid and other media, thereby improving the sealing of the docking position.

[0038] Furthermore, the lengths of connector 1, connector 2, 3 and connector 3, 4 are consistent. Through this design, the docking positions can be connected to the same depth position so as to offset against the connectors, thereby improving the tightness of the connection and the scope of application.

[0039] Working principle: When using the utility model, when docking the automobile oil pipe, since there are and are not limited to at least two joints with gradually increasing sizes at the docking position, and the joints can be movable through the limit part 1 5 and the limit part 2 11, the joints to be docked are exposed, and then the pipelines can be connected, so that different sizes of connection positions can be docked under the action of joints of different sizes, thereby improving applicability and scope of use, and after the joints are docked, the two clamping parts 9 can be connected through the fixing holes 10 and the fastening bolts, and the clamping part 9 can be elastically movable through the elastic part 8, so that the clamping part 9 can further stabilize and fix the docking position, thereby avoiding looseness at the joint position and improving the connection strength of the joint.
