Description

Technical Field

[0001] The utility model relates to the technical field of automobile cooling equipment, in particular to an expansion tube water tank. Background Art

[0002] The expansion tube water tank of an automobile can also be called an expansion water tank. Its main function is to accommodate the expansion of the coolant when the engine is working, and at the same time, it can also absorb and release the air in the cooling system. The expansion tube water tank is usually integrally formed. However, some expansion tube water tanks often need to add coolant or check the water tank status, which will cause the water tank lid to be frequently opened and closed, thus wearing the threaded mouth of the water tank. After being threadedly connected with the lid, water leakage will occur. And because the expansion tube water tank is integrally formed, it is necessary to replace the whole water tank. Although most of the water tank is still usable, only a small part of the threaded mouth needs to be repaired or replaced. The overall replacement will not only cause waste of resources but also increase the maintenance cost. Content of the Utility Model

[0026] Embodiment

[0027] Such as Figures 1-5As shown in the figure, a tube-expanding water tank proposed by the utility model includes a water tank body 1 and a water inlet 2 opened on the water tank body 1. A return pipe 14 and a water inlet pipe 15 are connected to the water tank body 1. It further includes: a threaded connection port 21 movably inserted into the water inlet 2, a threaded cover 3 is threadedly connected to the top end of the threaded connection port 21, and the other end of the threaded connection port 21 is provided with a plurality of top seams 29 arranged in a circumferential array to make the threaded connection port 21 break under extrusion force. The function of the top seam 29 is that after the threaded connection port 21 is clamped by pliers, the threaded connection port 21 is easier to break, and the broken threaded connection port 21 is convenient to take out from the water inlet 2. A plurality of strip-shaped grooves 31 are arranged in a circumferential array on the outer wall of the threaded cover 3; a connection mechanism provided on the threaded connection port 21 to fixedly install the threaded connection port 21 in the water inlet 2; a collar 27 installed in the water tank body 1 and abutted against the connection mechanism.

[0028] Furthermore, the connection mechanism includes a rubber sleeve 22 fixedly connected to one end of the threaded connection port 21 for passing through the water inlet 2 and then clamping the collar 27. A plurality of telescopic seams 23 are arranged in a circumferential array on the rubber sleeve 22. The function of the telescopic seam 23 is that when one end of the threaded connection port 21 passes through the water inlet 2, since the material of the rubber sleeve 22 is rubber, it is easier to deform after being extruded by the water inlet 2, and the deformed rubber sleeve 22 passes through the water inlet 2 more easily. A clamping groove 24 is provided on the rubber sleeve 22, and a sealing ring 28 that is snapped into the clamping groove 24 is provided on the surface of the collar 27 close to the rubber sleeve 22. The sealing ring 28 is a device for preventing liquid or gas leakage. Its main function is to ensure the sealing performance of the connection, prevent the leakage of the medium, and at the same time prevent external environmental substances from entering the system.

[0029] Among them, the connection mechanism further includes a threaded fastening sleeve 25 threadedly connected to the threaded connection port 21. After the threaded fastening sleeve 25 tightly clamps the water tank body 1, the threaded connection port 21 can be installed in the water inlet 2, and the tighter the threaded fastening sleeve 25 clamps the water tank body 1, the better the sealing performance of the threaded connection port 21 installed on the water inlet 2. A plurality of insertion holes 26 arranged linearly are provided on the outer wall of the threaded fastening sleeve 25. The function of the insertion holes 26 is to allow a rod-shaped tool such as a screwdriver to be inserted.

[0030] Furthermore, an installation edge 11 is fixedly sleeved on the outer wall of the water tank body 1, a plurality of installation blocks 12 are fixedly connected to the installation edge 11, and installation holes 13 for inserting bolts are provided on the installation blocks 12.

[0031] In this embodiment, when the tube-expanding water tank needs to be used, such as Figure 1As shown, when the thread at one end of the threaded connection port 21 close to the top seam 29 is damaged and cannot be used, only need to use pliers to clamp the end of the threaded connection port 21 with the top seam 29. And the top seam 29 is the weak point at one end of the threaded connection port 21 because these top seams 29 will cause stress concentration. When the threaded connection port 21 is under external pressure, these top seams 29 become the starting points of cracks, thus causing the threaded connection port 21 to be damaged. Then first take out the damaged threaded connection port 21 into the water inlet 2, and then insert the end of the new threaded connection port 21 with the rubber ferrule 22 into the water inlet 2. Through the expansion joint 23 opened on the threaded connection port 21, the threaded connection port 21 can be easily inserted into the water inlet 2. The threaded fastening ferrule 25 on the threaded connection port 21 inserted into the water inlet 2 will abut against the water tank body 1. Finally, insert a rod-shaped tool into the jack 26 on the threaded fastening ferrule 25 and rotate the tool, while fixing the threaded connection port 21 to prevent it from rotating in the water inlet 2. After the tool rotates, it drives the threaded fastening ferrule 25 to rotate on the threaded connection port 21. Since the threaded connection port 21 and the threaded fastening ferrule 25 are in threaded connection, the threaded fastening ferrule 25 will drive the threaded connection port 21 to move after abutting against the water tank body 1. And the threaded connection port 21 drives the rubber ferrule 22 thereon to tightly abut against the sealing ring 28 on the collar 27, thus completing the installation of the threaded connection port 21, which is simple and easy to operate.
