Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 7 shown, the present utility model provides an automobile radiator cooling pipe structure, including a plurality of elbow joints 1. One end of the elbow joint 1 is provided with a connecting male end 2, and the other end of the elbow joint 1 is provided with a connecting female end 3. Adjacent two elbow joints 1 are connected to each other through the connecting male end 2 and the connecting female end 3;

[0026] The connecting male end 2 includes a connection sleeve 21 movably sleeved on one end of the elbow joint 1, and a mating thread groove 26 is arranged inside the connection sleeve 21; the connecting female end 3 includes a connection bush 31 fixedly connected to the other end of the elbow joint 1, and a mating thread 34 is arranged outside the connection bush 31. The connection sleeve 21 is connected to the connection bush 31 on an adjacent elbow joint 1 through the cooperation of the mating thread groove 26 and the mating thread 34; due to the arrangement of the mating thread groove 26 and the mating thread 34, not only can the adjacent two elbow joints 1 be connected to obtain a complete cooling pipe, but also the bending state of the obtained complete cooling pipe can be adjusted, so that it can adapt to the installation environment in the engine compartment to a great extent, greatly facilitating the installation and use effects.

[0027] Among them, the inner and outer diameter dimensions of the connecting bushing 31 are the same as those of the elbow joint 1, and the connecting bushing 31 is integrally formed at one end of the elbow joint 1.

[0028] Among them, a reinforcing sleeve 32 is fixedly sleeved outside the connecting bushing 31, an adapting thread 34 is fixedly connected to the outer surface of the reinforcing sleeve 32, and a protective ring 33 is also fixedly sleeved outside the reinforcing sleeve 32. The protective ring 33 is located at one end of the adapting thread 34 outside the reinforcing sleeve 32 close to the elbow joint 1; due to the setting of the protective ring 33, it can not only protect the inside of the connecting sleeve 21 in cooperation with the connecting sleeve 21 to prevent moisture, dust, etc. in the air from entering and affecting the sealing effect of the primary gasket 24 and the secondary gasket 25; at the same time, it can also indicate the rotation state of the connecting sleeve 21 to the staff so that the staff can determine the completion of the connection between two adjacent elbow joints 1.

[0029] Among them, the elbow joint 1 is a horizontally placed "S" shape. The connecting female end 2 is connected to the downward end of the elbow joint 1, and the connecting male end 3 is connected to the upward end of the elbow joint 1. The connecting female end 2 is fixedly sleeved downward on the connecting male end 3.

[0030] Among them, a positioning ring 22 is rotatably clamped at the upper end of the connecting sleeve 21. The positioning ring 22 is fixedly sleeved on the outer surface of the elbow joint 1. An enhancing contact 23 is movably sleeved inside the connecting sleeve 21 between the positioning ring 22 and the adapting thread groove 26. The enhancing contact 23 is fixedly sleeved at the end of the elbow joint 1; due to the setting of the positioning ring 22, it can ensure that the connecting sleeve 21 can be in a fixed position at one end of the elbow joint 1, avoiding the inconvenience caused by its random sliding outside the elbow joint 1, and can ensure that when the connecting sleeve 21 rotates, it can pull the elbow joint 1 through the positioning ring 22 under the cooperation of the adapting thread groove 26 and the adapting thread 34, so that one end of it is connected to the other end of the adjacent elbow joint 1.

[0031] Among them, a primary gasket 24 at the front end of the elbow joint 1 is sleeved inside the enhancing contact 23, and a secondary gasket 25 is sleeved inside the connecting sleeve 21 at the front end of the enhancing contact 23. The hardness of the secondary gasket 25 is greater than that of the primary gasket 24.

[0032] Among them, the inner diameter dimension of the primary gasket 24 is the same as that of the elbow joint 1, the inner diameter dimension of the secondary gasket 25 is the same as the inner diameter dimension at the lower end of the enhancing contact 23. The outer surfaces of both the primary gasket 24 and the secondary gasket 25 are smooth, and the lower ends of the primary gasket 24 and the secondary gasket 25 are closely attached to the upper ends of the connecting bushing 31 and the reinforcing sleeve 32 respectively.

[0033] The working principle and usage process of the present utility model:

[0034] Connect the connecting male end 2 at one end of a bent pipe section 1 to the connecting female end 3 at one end of another bent pipe section 1. Repeat this process to connect multiple bent pipe sections 1 end to end to form a complete cooling pipe. Finally, connect one connecting male end 2 and one connecting female end 3 of the two bent pipe sections 1 at both ends to the cooling system to achieve cooling.

[0035] That is, insert the connecting bushing 31, the reinforcing sleeve 32, etc. as a whole into the connecting sleeve 21, and adjust the relative angle between two adjacent bent pipe sections 1 according to the needs of the installation environment. First, the mating thread groove 26 contacts the mating thread 34. At this time, rotate the connecting sleeve 21 and ensure that the angles of the two bent pipe sections 1 remain unchanged. Due to the rotation of the connecting sleeve 21, the positioning ring 22 drives the reinforcing contact 23 to approach the reinforcing sleeve 32, etc. under the cooperation of the mating thread groove 26 and the mating thread 34. First, make the front end of the connecting bushing 31 contact the primary sealing gasket 24 to form a sealed connection inside the pipe. Then, as the connecting sleeve 21 continues to rotate, make the front end of the reinforcing sleeve 32 contact the secondary sealing gasket 25 to form a secondary seal. Finally, when the front end of the connecting sleeve 21 contacts the protective ring 33, the two adjacent bent pipe sections 1 can be fixedly connected.
