Description

Technical Field

[0001] This utility model relates to the field of automotive parts and equipment technology, specifically a novel combined welded water-oil chamber sealing device. Background Technology

[0002] The automotive engine cooling system mainly consists of a radiator, fan, coolant jacket, water pump, and thermostat. The radiator, located at the front of the entire cooling system, is a crucial part of the engine's forced circulation cooling system. It comprises three parts: the inlet chamber, the outlet chamber, and the radiator core. The inlet chamber is an important component of the radiator, typically located at the top and bottom. Its function is to buffer the coolant flowing into the radiator core and to re-distribute the cooled water back to the engine to ensure effective heat dissipation.

[0003] During driving, cars inevitably experience vibrations depending on road conditions. The radiator water chamber is subjected to long-term vibrations, so the structural strength of the radiator water chamber is a key factor affecting the service life of the radiator. Currently used radiator water chambers and rubber hoses are prone to detachment and unstable connection due to water circulation and vibration during operation.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a novel combined welded water-oil chamber sealing device, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel combined welded water-oil chamber sealing device, comprising a water-oil chamber body, an outlet, an inlet, an outlet connecting pipe, and an inlet connecting pipe. The water-oil chamber body is provided with an outlet and an inlet. The outlet is provided with a soft pad, a clip, and a post. The inlet is provided with a sealing connection structure, which includes a first abutment, a second abutment, a ring, and a limiting ball. A first connecting post is fixedly connected to the inner wall of the inlet, and a first abutment is slidably connected to one end of the first connecting post.

[0009] Preferably, the first connecting column has multiple holes and a central slot at one end away from the main body of the water-oil chamber. The end of the first abutment passes through the slot and is slidably connected to the first connecting column. The other end of the first abutment abuts against the inner wall of the inlet pipe.

[0010] Preferably, the inlet pipe opening has multiple circumferentially formed grooves, each groove contains a limiting ball, and a ring is slidably connected to the outside of the inlet pipe opening.

[0011] Preferably, the ring sleeve has multiple protrusions, the positions of which are arranged in the same way as the positions of multiple limiting balls. The inner wall of the ring sleeve has a limiting groove, and a spring is provided in the limiting groove. The end of the spring is fixed to the outer wall of the inlet.

[0014] (III) Beneficial Effects

[0015] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a novel combined welded water-oil chamber sealing device, which is equipped with a soft pad and a clamp and a post at the outlet.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-4 As shown: A novel combined welded water-oil chamber sealing device includes a water-oil chamber body 1, an outlet 2, an inlet 3, an outlet connecting pipe 6, and an inlet connecting pipe 13. The water-oil chamber body 1 is provided with an outlet 2 and an inlet 3. A soft pad 4, a clip, and a post 5 are provided at the outlet 2. A sealing connection structure is provided inside the inlet 3. The sealing connection structure includes a first abutment post 8, a second abutment post 12, a ring sleeve 10, and a limiting ball 11. A first connecting post 16 is fixedly connected to the inner wall of the inlet 3. One end of the first connecting post 16 is slidably connected to the first abutment post 8. The outlet connecting pipe 6 is connected to the outlet port 2, and the inlet connecting pipe 13 is connected to the inlet port 3. When the outlet port 2 is connected to the outlet connecting pipe 6, the outlet connecting pipe 6 and the outlet port 2 are aligned, and then the two are brought close together until they abut against each other. Then the outlet connecting pipe 6 is rotated until the connecting pipe clamp and post abut against each other and the two clamp the soft pad 4. The outlet connecting pipe 6 and the outlet port 2 are also provided with sealing rings to achieve a sealed connection.

[0023] The first connecting post 16 has multiple holes and a central slot at its end away from the main body 1 of the water-oil chamber. The end of the first abutment post 8 passes through this slot and is slidably connected to the first connecting post 16. The other end of the first abutment post 8 abuts against the inner wall of the inlet 3. When connecting the inlet pipe 13 to the inlet 3, align the inlet pipe 13 with the inlet 3. The size of the inlet pipe 13 is the same as the size of the inlet 3 pipe. Then, move the ring 10 backward. At this time, the spring 9 inside the ring 10 contracts, and the protrusion on the ring 10 moves backward from the protrusion that was originally pressing against the groove on the inlet 3 pipe opening. Then, insert the inlet pipe 13 into the inlet 3. Inside, as the inlet connecting pipe 13 moves until the second abutment 12 abuts against the first abutment 8, and continues to move until the first abutment 8 is blocked by the first connecting post 16, it reaches its extreme point. During this process, the limiting ball 11 is first slightly pushed up, and then falls into the groove 14 on the outer wall of the inlet connecting pipe 13. Then the ring sleeve 10 is released, and under the action of the spring 9, the ring sleeve 10 is pushed forward to return to its original position. At this time, the protrusion on the ring sleeve 9 is pushed above the limiting ball 11 again. At this time, half of the limiting ball 11 is stuck on the inlet 3, and the other half is stuck in the groove 14, thus achieving the fixed limiting of the inlet 3 and the inlet connecting pipe 13.

[0024] Multiple slots are circumferentially opened at the inlet 3, and a limiting ball 11 is installed in the slot. The slot is not completely open, and the slot itself is spherical, gradually narrowing at the lower end. Therefore, the limiting ball 11 can move downwards without falling out, thus locking and securing the two. A ring sleeve 10 is slidably connected to the outside of the inlet 3. The inlet 3 and the inlet connecting pipe 13 are internally connected, thus achieving good sealing.

[0025] The ring 10 has multiple protrusions, and the positions of the protrusions are arranged in the same way as the positions of the multiple limiting balls 11. The inner wall of the ring 10 has a limiting groove, and a spring 9 is provided in the limiting groove. The end of the spring 9 is fixed to the outer wall of the inlet 3.

[0026] The inlet pipe 13 is provided with a second abutment 12, which is arranged opposite to the first abutment 8. A second connecting post 15 is also fixed in the side wall of the inlet pipe 13. The second abutment 12 and the second connecting post 15 are slidably connected. The second connecting post 15 and the first connecting post 16 are provided with multiple holes near the first abutment 8 and the second abutment 12 to facilitate the flow of liquid in and out.

[0027] The side wall of the inlet connecting pipe 13 is provided with multiple grooves 14 in the circumferential direction, and the arrangement of the multiple grooves 14 is the same as the position of the limiting ball 11.

[0028] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
