DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application embodiment discloses a coolant pot with stable connection. Figure 1 The coolant pot with stable connection includes a pot body 1, a liquid outlet pipe 2 and an anti-falling component 3. The pot body 1 contains coolant, and the liquid outlet pipe 2 is welded to the bottom side of the pot body 1 by ultrasonic welding technology. The liquid outlet pipe 2 is connected to the inside of the pot body 1. A connecting hose is sleeved on the liquid outlet pipe 2, and the other end of the connecting hose is connected to the cooling circulation system of the car, so that the coolant cools the engine and the battery. The anti-falling component 3 is slidably installed on the liquid outlet pipe 2. After sliding, the anti-falling component 3 is located inside the connecting hose and can be inserted into the wall thickness of the connecting hose so that the connecting hose is not easy to fall off from the liquid outlet pipe 2.

[0027] Reference Figure 2 The liquid outlet pipe 2 includes a guide portion 21, a connecting portion 22 and an anti-detachment portion 23. The connecting portion 22 is located between the guide portion 21 and the anti-detachment portion 23. When connected, the guide portion 21 will be inserted into the connecting hose first, and the end of the anti-detachment portion 23 away from the guide portion 21 is installed on the liquid pot body 1.

[0028] The outer diameter of the guide portion 21 is smaller than the inner diameter of the connecting hose, and the guide portion 21 plays a role of guiding the pre-positioning after being inserted into the connecting hose. The outer diameter of the connecting portion 22 is larger than the outer diameter of the guide portion 21 and the outer diameter of the connecting portion 22 is slightly larger than the inner diameter of the connecting hose, and when the connecting hose is sleeved on the connecting portion 22, the connecting hose will have an interference fit with the connecting portion 22 and will not be easily separated.

[0029] Reference Figure 2In order to facilitate the connection hose to be set from the guide part 21 to the connection part 22, the outer edge of the connection part 22 close to the guide part 21 is set as a guide slope 24, that is, the guide slope 24 gradually expands outward from the guide part 21 to the connection part 22. Under the action of the guide slope 24, the connection hose is gradually expanded and then set on the connection part 22.

[0030] The connection part 22 is provided with a sealing groove 25 for installing a sealing ring, and the sealing groove 25 is an annular groove. The connection part 22 is inserted into the connection hose and the connection hose is tightened and fixed by the throat hoop, and the throat hoop will be located at the connection part 22.

[0031] Reference Figure 2 The outer diameter of the anti-dropout part 23 is smaller than the outer diameter of the connecting part 22, and the anti-dropout component 3 is slidably installed on the anti-dropout part 23. After the connecting hose is sleeved on the connecting part 22, it continues to move toward the anti-dropout part 23 and sleeves on the position of part of the anti-dropout part 23, thereby facilitating the matching connection between the anti-dropout component 3 and the connecting hose.

[0032] Reference Figure 2 and Figure 3 The anti-drop assembly 3 includes a collar 31 and a deformable arc piece 32. The collar 31 is sleeved on the anti-drop portion 23, and the collar 31 slides on the anti-drop portion 23 along its own axial direction. The deformable arc piece 32 is integrally formed on one side of the collar 31 close to the connecting portion 22, and a plurality of deformable arc pieces 32 are provided, and the plurality of deformable arc pieces 32 are evenly spaced and arranged on the collar 31 along the circumference of the collar 31. In this embodiment, eight deformable arc pieces 32 are preferably provided, and the structures of the eight deformable arc pieces 32 are the same. The following is described by taking one deformable arc piece 32 as an example.

[0033] Reference Figure 2 and Figure 3 The deformable arc piece 32 includes a smooth portion 33 and a burr portion 34. The smooth portion 33 is located on the side of the burr portion 34 close to the collar 31. A plurality of burrs 35 are integrally formed on the outer wall of the burr portion 34, and the plurality of burrs 35 are arranged at intervals. A conical surface 26 is provided on the side of the connecting portion 22 close to the anti-slip portion 23. The conical surface 26 gradually inclines toward the outer wall away from the anti-slip portion 23 along the direction from the anti-slip portion 23 to the connecting portion 22. When the collar 31 drives the deformable arc piece 32 to move toward the connecting portion 22, the deformable arc piece 32 expands outward under the action of the conical surface 26, so that the burrs 35 penetrate into the connecting hose. When the connecting hose is pulled out by moving away from the liquid outlet pipe 2, the expansion angle of the deformable arc piece 32 becomes larger, and the burrs 35 penetrate deeper into the connecting hose, so that the connecting hose will be connected more stably.

[0034] An unlocking ring 36 is sleeved on the collar 31, and the unlocking ring 36 is threadedly mounted on the collar 31. When the unlocking ring 36 moves to the smooth portion 33, the plurality of deformed arc plates shrink synchronously, so that the top thorn 35 is pulled out from the connecting hose, thereby pulling out the connecting hose.

[0035] Reference Figure 2 and Figure 3 In order to prevent the collar 31 from rotating synchronously with the unlocking ring 36 when the unlocking ring 36 is rotated, a limiting block 37 is integrally formed on the inner wall of the collar 31, and a sliding groove 27 is opened on the outer wall of the anti-slip portion 23. The extending direction of the sliding groove 27 is consistent with the moving direction of the collar 31. The limiting block 37 is inserted into the limiting groove and slides directionally along the opening direction of the limiting groove.

[0036] The implementation principle of a coolant pot with a stable connection according to an embodiment of the present application is as follows: first, the connecting hose is sequentially inserted into the guide portion 21, the connecting portion 22 and the anti-slip portion 23, and then the collar 31 is pushed to drive the deformed arc piece 32 to move in the direction close to the connecting portion 22. The deformed arc piece 32 expands outward under the action of the conical surface 26, so that the top thorn 35 penetrates into the connecting hose. At this time, if the connecting hose is driven to move away from the liquid outlet pipe 2 and pulled out, the expansion angle of the deformed arc piece 32 becomes larger, and the top thorn 35 penetrates deeper into the connecting hose, so that the connecting hose will be connected more stably. Finally, the throat clamp is sleeved on the connecting portion 22, and the throat clamp is driven to tighten, and the connecting hose is fixed to the liquid outlet pipe 2.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
