[0019] The technical solution in the embodiment of the present application is to solve the problems mentioned in the above background technology, and the overall idea is as follows:
[0020] See also Figure 1 A fracture-proof quick transition joint includes a head 10 and a tail 20, wherein the head 10 and the tail 20 are fixedly connected, and a reinforcing rib 30 is arranged at the connection between the head 10 and the tail 20, and the reinforcing rib 30 is evenly distributed around the circumference. The reinforcing rib 30 can improve the connection strength between the head 10 and the tail 20 and reduce the risk of fracture caused by stress concentration.
[0021] See also Figure 1-Figure 4 , the outer circle of the head 10 is provided with a buckle A40. Here, the buckle A40 is used for the head 10 to be connected to the external filter quickly.
[0022] See also Figure 1-Figure 4 , an oil pipe 50 is plugged into the tail portion 20. Here, the oil pipe 50 is plugged into the tail portion 20 so as to supply oil to the engine at the rear.
[0023] See also Figure 1-Figure 2 , a convex ring 60 is provided on the tail portion 20. Here, the convex ring 60 is used to seal and prevent the oil pipe 50 from falling off.
[0024] See also Figure 2-Figure 4The oil pipe 50 is covered with a sleeve 70, the lower end of the sleeve 70 is engaged with the reinforcing rib 30, and the rear end face of the sleeve 70 is in contact with the end face of the head 10. Here, the sleeve 70 is covered on the oil pipe 50, and then the lower end of the sleeve 70 is engaged with the reinforcing rib 30, which can reduce looseness and prevent self-rotation, and the rear end face of the sleeve 70 is in contact with the end face of the head 10 to provide additional support for the oil pipe 50.
[0025] See also Figure 2-Figure 4 The front end of the sleeve 70 is provided with an elastic strip 80 in a circumferential array, and the strip 80 is movably pressed against the outer circle of the oil pipe 50. Here, the strip 80 is used to press on the outer periphery of the oil pipe 50, so that the inner wall of the oil pipe 50 can further squeeze the convex ring 60, thereby obtaining a better sealing and anti-slip effect.
[0026] See also Figure 2-Figure 4 The sleeve 70 is covered with a cone sleeve 90, and the inner wall of the cone sleeve 90 is provided with a cone surface, and the cone sleeve 90 uses the cone surface to press against all the pressure strips 80. Here, the cone sleeve 90 is sleeved on the outer periphery of the sleeve 70 and moves axially, and the cone surface is used to make all the pressure strips 80 shrink inward, thereby squeezing the outer wall of the oil pipe 50 to form a lock.
[0027] See also Figure 2-Figure 4 The rear end surface of the cone sleeve 90 is provided with a buckle B100, and the outer circle of the head 10 is provided with a buckle point 110 adapted to the buckle B100. Here, the cone sleeve 90 is moved axially, and after squeezing all the pressure strips 80, the buckle B100 is buckled on the buckle point 110 on the outer circle of the head 10, so that the cone sleeve 90 and the head 10 are connected and fixed together to prevent loosening.
[0028] When the present application is used: the cone sleeve 90 is first put onto the oil pipe 50, and then the sleeve 70 is put onto the oil pipe 50. After the oil pipe 50 is inserted into the tail 20, the sleeve 70 is pushed to the position of the head 10, so that the end face of the sleeve 70 fits with the end face of the head 10, and the reinforcing rib 30 is engaged with the sleeve 70. Then the cone sleeve 90 is pushed toward the head 10, and the cone surface is used to make all the pressure strips 80 shrink inward, thereby squeezing the outer wall of the oil pipe 50, until the buckle B100 is buckled on the buckle point 110 of the outer circle of the head 10, thereby connecting and fixing the cone sleeve 90 and the head 10 together to prevent loosening.
[0029] In summary, the reinforcing rib 30 can improve the connection strength between the head 10 and the tail 20, reduce the risk of fracture due to stress concentration, and can be fixed to the outer circle of the oil pipe 50 by the cone sleeve 90 and the sleeve 70, and remain connected to the head 10 and the reinforcing rib 30, thereby providing additional support force and further reducing the risk of fracture of the tail 20.
[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
