Description

Technical Field

[0001] This utility model relates to the field of automotive heater core technology, and in particular to a pipe interface assembly for automotive heater cores. Background Technology

[0002] The car heater core is a major component of the car engine cooling system. Its function is to circulate the high-temperature coolant in the engine. When the high-temperature coolant in the engine passes through the heater core, the heater core exchanges heat and rises in temperature. The blower continuously blows air into the heater core, and the blown air is discharged into the car cabin to form warm air after passing through the heater core.

[0003] Existing heater core pipe interfaces often use threaded interfaces, which require manual rotation of the interface pipe to connect to the threaded interface. This is time-consuming, labor-intensive, and inconvenient to operate. In addition, the dustproof sealing effect at the pipe interface is not good. This paper proposes a pipe interface assembly for automotive heater cores to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in the existing technology, this utility model proposes a pipe interface assembly for automotive heater cores, which solves the technical problems of existing heater core pipe interfaces often using threaded interfaces, requiring manual and continuous rotation of the interface pipe to connect to the threaded interface, which is time-consuming, labor-intensive, inconvenient to operate, and has poor dustproof sealing effect at the pipe interface.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe interface assembly for an automotive heater core includes a first pipe and a second pipe. The first pipe has a connector, and the second pipe has an annular sealing block on its annular sidewall near the connector. The connector has a circular slot on its sidewall opposite the second pipe, and the annular sealing block is inserted into the circular slot and pressed against it. The annular inner wall of the circular slot has a snap-fit ​​mechanism that snaps and fixes the annular sealing block. The annular sidewall of the second pipe has an annular limiting protrusion, and the annular sidewall of the second pipe between the annular sealing block and the annular limiting protrusion has a locking mechanism.

[0007] Preferably, the sidewall of the annular sealing block is seamlessly connected to the sidewall of the first pipe, the annular sealing block is a corrosion-resistant rubber product, and the annular limiting protrusion is integrally formed with the second pipe.

[0008] Preferably, the annular sealing block has an annular groove on the side wall facing the circular slot, and the circular slot has an annular block on the inner wall facing the second pipe. The annular block is inserted into the annular groove, and the annular block and the first pipe are integrally formed.

[0009] Preferably, the snap-fit ​​mechanism includes two symmetrically distributed circular grooves on the annular inner wall of the circular slot, a first spring is fixedly connected to the opposite sidewall of each of the two circular grooves, and a circular snap-fit ​​block is fixedly connected to the opposite sidewall of each of the two first springs. The annular sealing block has two symmetrically distributed circular slots on its annular sidewall, and the two circular snap-fit ​​blocks are respectively inserted into the two circular slots.

[0010] Preferably, each of the two circular slots has a rectangular opening on its annular inner wall, the rectangular opening being connected to the circular slot, and a pull block being fixedly connected to the annular sidewall of each of the two circular blocks away from the first spring, the two pull blocks respectively passing through the two rectangular openings.

[0011] Preferably, the locking mechanism includes two annular limiting grooves disposed on the annular sidewall of the second pipe between the annular sealing block and the annular limiting protrusion. An arc-shaped locking block is fitted onto one of the annular limiting grooves. The movable end of the arc-shaped locking block is flat. A U-shaped limiting block is fixedly connected to the sidewall of the arc-shaped locking block near the movable end. The flat movable end of the arc-shaped locking block passes through the U-shaped limiting block. A clamping block is fixedly connected to the movable end of the arc-shaped locking block. A fixing block is fixedly connected to the arc-shaped sidewall of the arc-shaped locking block away from the U-shaped limiting block. A second spring is fixedly connected between the clamping block and the fixing block.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By connecting the first pipe and the second pipe, the annular sealing block is inserted into the circular slot, and the annular locking block is inserted into the annular slot. The first spring in the circular slot drives the circular locking block to be inserted into the circular slot, effectively locking and positioning the second pipe in the circular slot. No manual rotation connection is required, saving time and effort. The structure is simple and easy to operate.

[0014] 2. By pressing the U-shaped limiting block and clamping block, the arc-shaped locking block expands and stretches the second spring between the clamping block and the fixed block.

Therefore, they should not be construed as limitations on this utility model.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A pipe interface assembly for an automotive heater core includes a first pipe 1 and a second pipe 2. The first pipe 1 is provided with a connector 3. The second pipe 2 is provided with an annular sealing block 4 on its annular sidewall near the connector 3. The sidewall of the annular sealing block 4 is seamlessly connected to the sidewall of the first pipe 1. The annular sealing block 4 is made of corrosion-resistant rubber. An annular limiting protrusion 6 is integrally formed with the second pipe 2. The connector 3 is provided with a circular slot 5 on its sidewall facing the second pipe 2. The annular sealing block 4 is inserted into the circular slot 5 and pressed against it, connecting the first pipe 1 and the second pipe 2 so that the annular sealing block 4 is inserted into the circular slot 5 on the connector 3. The annular sealing block 4 is provided with an annular groove 7 on its sidewall facing the circular slot 5. The circular slot 5 is provided with an annular locking block 8 on its inner wall facing the second pipe 2. The annular locking block 8 is inserted into the annular groove 7. The annular locking block 8 is integrally formed with the first pipe 1. The annular locking block 8 is inserted into the annular groove 7, effectively limiting the annular sealing block 4 in the circular slot 5.

[0023] A snap-fit ​​mechanism is provided on the annular inner wall of the circular slot 5. The snap-fit ​​mechanism is snapped and fixed to the annular sealing block 4. The snap-fit ​​mechanism includes two symmetrically distributed circular grooves 9 on the annular inner wall of the circular slot 5. A first spring 10 is fixedly connected to the opposite side wall of each of the two circular grooves 9. A circular locking block 11 is fixedly connected to the opposite side wall of each of the two first springs 10. The annular side wall of the annular sealing block 4 is provided with two symmetrically distributed circular slots 12. When the two pull blocks 14 are released, the compressed first springs 10 are elastically reset, and the two circular locking blocks 11 are respectively inserted into the two circular slots 12, effectively locking and positioning the annular sealing block 4 in the circular slot 5 without manual rotation. The adapter is time-saving and labor-saving, with a simple structure and convenient operation. Two circular locking blocks 11 are respectively inserted into two circular locking slots 12. The inner walls of the two circular slots 9 are provided with rectangular openings 13, which are connected to the circular slots 5. Pulling blocks 14 are fixedly connected to the annular sidewalls of the two circular locking blocks 11 away from the first spring 10. The two pulling blocks 14 are respectively set through the two rectangular openings 13. The rectangular openings 13 are used to limit the movement range of the pulling blocks 14. Pulling the two pulling blocks 14 along the rectangular openings 13 on both sides causes the two circular locking blocks 11 to retract into the circular slots 9 and compress the first spring 10 until the annular sealing block 4 can be completely inserted into the circular slot 5.

[0024] The second pipe 2 has an annular limiting protrusion 6 on its annular sidewall. A locking mechanism is provided on the annular sidewall of the second pipe 2 between the annular sealing block 4 and the annular limiting protrusion 6. The locking mechanism includes two annular limiting grooves 15 on the annular sidewall of the second pipe 2 between the annular sealing block 4 and the annular limiting protrusion 6. An arc-shaped locking block 16 is fitted onto one of the annular limiting grooves 15. The movable end of the arc-shaped locking block 16 is flat. A U-shaped limiting block 17 is fixedly connected to the sidewall of the arc-shaped locking block 16 near its movable end. The flat movable end of the arc-shaped locking block 16 passes through the U-shaped limiting block 17. A clamping block 18 is fixedly connected. A fixing block 19 is fixedly connected to the arc-shaped locking block 16 away from the arc-shaped limiting block 17. A second spring 20 is fixedly connected between the clamping block 18 and the fixing block 19. Pressing the U-shaped limiting block 17 and the clamping block 18 causes the arc-shaped locking block 16 to expand and stretch the second spring 20 between the clamping block 18 and the fixing block 19. The arc-shaped locking block 16 is moved and inserted into one of the annular limiting grooves 15. After the clamping block 18 is released, the second spring 20 elastically resets and cooperates with the clamping block 18 to drive the arc-shaped locking block 16 to press and position itself in the annular limiting groove 15. This, together with the annular sealing block 4, effectively seals the interface between the first pipe 1 and the second pipe 2.

[0025] In use, the first pipe 1 is connected to the second pipe 2, so that the annular sealing block 4 is inserted into the circular slot 5 on the connector 3. Pulling the two pull blocks 14 along the rectangular openings 13 on both sides causes the two circular locking blocks 11 to retract into the circular grooves 9 and compress the first spring 10 until the annular sealing block 4 can be fully inserted into the circular slot 5. At this time, the annular locking block 8 is inserted into the annular locking groove 7. Releasing the two pull blocks 14 causes the compressed first spring 10 to elastically return to its original position, and the two circular locking blocks 11 are respectively inserted into the two circular locking grooves 12, effectively sealing the annular sealing block 4. The U-shaped sealing block 4 is locked and positioned in the circular slot 5, eliminating the need for manual rotation connection, saving time and effort. The structure is simple and easy to operate. Pressing the U-shaped limiting block 17 and the clamping block 18 causes the arc-shaped locking block 16 to expand and stretch the second spring 20 between the clamping block 18 and the fixing block 19. The arc-shaped locking block 16 is moved and inserted into one of the annular limiting grooves 15. After the clamping block 18 is released, the second spring 20 elastically resets and, together with the clamping block 18, causes the arc-shaped locking block 16 to be pressed and positioned in the annular limiting groove 15. Together with the annular sealing block 4, it effectively seals the interface between the first pipe 1 and the second pipe 2.
