[0005] The utility model is implemented as follows: a brake master cylinder oil pipe joint includes an upper connecting head and a positioning paddle, wherein the positioning paddle is located at the lower end of the upper connecting head and is made of elastic material, the outer side of the upper connecting head is snap-connected with a lower connecting head, the top of the upper connecting head is set as an annular structure, and the bottom of the annular structure is fixedly connected with a plurality of fixing bolts symmetrically distributed in the center, and the outer side of the fixing bolt is threadedly connected with a nut bolt.

[0006] Preferably, a limiting ring is fixedly connected to the outer side of the nut sleeve bolt, a clamping ring is provided inside the lower connecting head, and the clamping ring is clamped and connected to the outer side of the positioning paddle.

[0007] Preferably, a plurality of positioning holes which are centrally symmetrically distributed are provided on the top of the lower connecting head, and fixing bolts are provided inside the plurality of positioning holes.

[0008] Preferably, a plurality of sliding holes distributed in a centrally symmetrical manner are provided at the bottom of the lower connecting head, and the plurality of sliding holes correspond to the positioning holes one by one.

[0010] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0011] The lower connecting head and the upper connecting head are reinforced by multiple threaded bolts, so that the force caused by the water hammer effect caused by multiple impacts of the oil flow by the multiple threaded bolts can be dispersed to prevent the water hammer effect from damaging the equipment. When the fixing bolts and the threaded bolts are successfully connected, the threaded bolts will drive the lower connecting head and the upper connecting head to fit more tightly, thereby enhancing the sealing of the connection between the lower connecting head and the upper connecting head.
