Description

Technical Field

[0001] This utility model relates to the field of radiator interface sealing technology, and in particular to an interface sealing device for radiators. Background Technology

[0002] Radiator interface sealing is a crucial step in ensuring the normal operation of the radiator, preventing coolant leakage, and guaranteeing the performance of the cooling system. The coolant in the radiator circulates under high temperature and pressure. If the interface is not properly sealed, the coolant will leak out. This will not only cause the coolant level to drop, affecting the cooling effect, but may also cause the engine to overheat and damage engine components.

[0003] Existing radiators are usually connected to an expansion tank via a small-diameter pipe, but the interface and the tank pipe are usually connected by a plug, which results in poor sealing and an unstable connection that is very easy to break. Utility Model Content

[0004] The purpose of this utility model is to provide an interface sealing device for radiators, which solves the problem that the existing radiator interfaces and water tank pipes are usually connected by plugging, resulting in poor sealing and unstable connection between the interface and the water tank pipe, making it easy to break.

[0005] To achieve the above objectives, a radiator interface sealing device is provided, comprising: a mounting plate, wherein a radiator interface is provided inside the mounting plate, a base plate is movably connected to the top of the mounting plate, a first connecting sleeve is fixedly connected to the top of the base plate, and the first connecting sleeve is sleeved on the outer wall of the radiator interface, movable holes are provided on both sides of the first connecting sleeve, a positioning spring is fixedly connected inside the movable hole, a positioning block is fixedly connected to the other end of the positioning spring, a water tank pipe is movably connected to the outer wall of the radiator interface, and a second connecting sleeve is fixedly connected to the outer wall of the water tank pipe, thereby enhancing the stability of the connection between the radiator interface and the water tank pipe, and simultaneously enhancing the sealing performance of the radiator interface;

[0006] A sealing ring is fitted on the outer wall of the bottom end of the second connecting sleeve, and a sealing gasket is provided on the top of the sealing ring to facilitate the sealing of the connection between the second connecting sleeve and the base plate.

[0007] According to the aforementioned interface sealing device for a radiator, the mounting plate, base plate, sealing ring, and sealing gasket are all provided with fixing holes, and the positions of the fixing holes are all corresponding to each other, which facilitates the installation of the first connecting sleeve and the sealing ring.

[0008] According to the aforementioned interface sealing device for a radiator, the inner wall of the fixing hole at the top of the mounting plate is provided with threads, and the fixing hole is engaged with a fixing bolt through the threads, which facilitates the installation and removal of the sealing ring, and thus facilitates the replacement of the sealing ring.

[0009] According to the aforementioned interface sealing device for a radiator, the diameter of the first connecting sleeve is smaller than the diameter of the second connecting sleeve, and the diameter of the radiator interface is smaller than the diameter of the water tank pipe, which facilitates the connection between the radiator interface and the water tank pipe.

[0010] According to the aforementioned interface sealing device for a radiator, the sealing ring is made of rubber material, which facilitates the sealing of the radiator interface.

[0011] According to the aforementioned interface sealing device for a radiator, the diameter of the movable hole is larger than the diameter of the positioning block, and the positioning block is slidably connected to the inner wall of the movable hole, which facilitates the retraction of the positioning block and thus facilitates the connection of the first connecting sleeve and the second connecting sleeve.

[0012] According to the aforementioned interface sealing device for a radiator, the shape and size of the positioning block are matched with the shape and size of the positioning hole. When the position of the positioning block corresponds to the positioning hole, the positioning block is movably connected to the positioning hole under the action of the positioning spring, thereby enhancing the stability of the connection between the first connecting sleeve and the second connecting sleeve.

[0013] According to the aforementioned interface sealing device for a radiator, when the positioning block is connected to the positioning hole, the sealing ring is fitted at the connection between the second connecting sleeve and the base plate to facilitate sealing at the connection between the second connecting sleeve and the base plate.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The radiator interface sealing device uses an installation plate on the outer wall of the radiator interface, a base plate and a first connecting sleeve on the radiator interface, and a second connecting sleeve at one end of the water tank pipe. The connection between the first and second connecting sleeves is achieved by inserting the first and second connecting sleeves. The positioning springs on both sides of the first connecting sleeve drive the positioning block to connect with the positioning holes on both sides of the second connecting sleeve, thereby strengthening the connection between the first and second connecting sleeves, improving the stability of the connection between the radiator interface and the water tank pipe, and indirectly improving the sealing performance of the connection between the radiator interface and the water tank pipe.

[0016] 2. The interface sealing device of this radiator improves the sealing performance at the connection between the second connecting sleeve and the base plate by setting a sealing ring on the connection between the second connecting sleeve and the base plate. At the same time, both the sealing ring and the sealing gasket are connected to the mounting plate by fixing bolts, which facilitates installation and disassembly, and thus facilitates the replacement of the sealing ring.

[0032] A sealing ring 4 is fitted on the outer wall of the bottom end of the second connecting sleeve 13, and a sealing gasket 5 is provided on the top of the sealing ring 4. The sealing ring 4 seals the connection between the second connecting sleeve 13 and the base plate 3, thereby improving the sealing performance of the connection between the radiator interface 2 and the water tank pipe 12.

[0033] Fixing holes 6 are provided on the mounting plate 1, base plate 3, sealing ring 4, and sealing gasket 5, and the positions of the fixing holes 6 correspond to each other. The inner wall of the fixing hole 6 on the top of the mounting plate 1 is threaded, and the fixing hole 6 is engaged with the fixing bolt 7 through the thread. The fixing bolt 7 and the fixing hole 6 are used to fix the base plate 3, sealing ring 4, and sealing gasket 5, which is convenient for installation and disassembly. The diameter of the first connecting sleeve 8 is smaller than the diameter of the second connecting sleeve 13, and the diameter of the radiator interface 2 is smaller than the diameter of the water tank pipe 12, which facilitates the connection of the first connecting sleeve 8 and the second connecting sleeve 13, and also facilitates the connection of the radiator interface 2 and the water tank pipe 12.

The fixing holes 6 on the mounting plate 1, base plate 3, sealing ring 4 and sealing gasket 5 are aligned one by one, and the fixing bolts 7 are inserted and tightened in sequence. The second connecting sleeve 13 at one end of the water tank pipe 12 is inserted into the first connecting sleeve 8, thereby driving the water tank pipe 12 to connect with the radiator interface 2.
