Description

Technical Field

[0001] The utility model belongs to the field of automotive thermal management components, and particularly relates to a quick-connect throttle structure. Background Art

[0002] In the existing automotive cooling circuit, in addition to the need to use quick-connect fittings ( Figure 1 ), the exhaust pipe also requires a separate assembly of a throttle valve ( Figure 2 ), which is used to adjust the flow rate from the radiator and the engine to the expansion tank. Since the throttle valve is small and not easily recognizable after assembly, there is a risk of missing the installation of the throttle valve, which will affect the heating performance of the air conditioner in winter and increase the cost of the whole vehicle.

[0003] Therefore, the combination of functional components, throttle structures, and quick-connect structures can meet the requirements of lightweight, fewer components, and low cost, and this structure is also applicable to pipelines with flow regulation requirements in the cooling system. Summary of the Utility Model

[0004] Aiming at the deficiency that the existing automotive cooling system is prone to missing the installation of the throttle valve, the utility model provides a quick-connect throttle structure, which can reduce the material cost and avoid missing the installation of the throttle valve.

[0006] A quick-connect throttle structure, comprising: a quick-connect female fitting and a throttle structure;

[0007] The throttle structure is arranged in the cavity of the quick-connect female fitting;

[0008] The throttle structure and the quick-connect female fitting are integrally formed by injection molding.

[0009] In some embodiments, the front end of the housing of the quick-connect female fitting has an annular anti-drop structure.

[0010] In some embodiments, the quick-connect throttle structure further includes a sealing ring, a locking spring, and a quick-connect male fitting.

[0011] In some embodiments, the sealing ring is sleeved outside the quick-connect female fitting.

[0012] In some embodiments, the locking spring is arranged outside the housing of the quick-connect female fitting.

[0013] In some embodiments, the top end of the quick-connect male fitting has a connecting boss. When the quick-connect male fitting is docked with the quick-connect female fitting, the boss at the top end of the quick-connect male fitting is fastened with the locking spring of the quick-connect female fitting.

[0014] In some embodiments, the sealing ring is arranged between the quick-connect female fitting and the quick-connect male fitting.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. It reduces the material cost and realizes the light weight of the throttling structure;

[0017] 2. It can install the throttle valve quickly and conveniently, thus avoiding the risk of missing the installation of the throttle valve.

[0018] Other features and advantages of the utility model will be described in the subsequent specification, and, in part, will be obvious from the specification, or will be understood by implementing the present usage information. The objectives and other advantages of the utility model can be realized and obtained by the structures pointed out in the specification, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The drawings are only for illustrative purposes and cannot be construed as a limitation to this patent; for better illustrating this embodiment, some components in the drawings will be omitted, enlarged or reduced, and do not represent the actual size of the product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as a limitation to this patent.

[0026] [[ID=4'2]]As Figure 3As shown, the utility model discloses a quick-connect throttling structure, which includes: a quick-connect female joint 1 and a throttling structure 2. The throttling structure 2 is arranged in the cavity of the quick-connect female joint 1. Accordingly, a corresponding mold is made, and the quick-connect throttling structure is obtained by integrally injection molding through the mold.

[0027] Specifically, the quick-connect female joint 1 is a joint for quickly connecting the expansion tank pipeline, and the front end of the shell has an annular anti-detachment structure; the throttling structure 2 is a component that can both remove air and restrict the flow of liquid, enabling the coolant to remove air in the circuit without excessive loss that affects temperature maintenance.

[0028] Specifically, as Figure 3 shown, the quick-connect throttling structure further includes a sealing ring 3 and a locking spring 4. Among them, the sealing ring 3 is sleeved on the outside of the quick-connect female joint to ensure the sealing between the quick-connect female joint 1 and the quick-connect male joint 5; the locking spring 4 is arranged on the outside of the shell of the quick-connect female joint to buckle and fix the inserted quick-connect male joint 5.

[0029] The quick-connect joint structure with a throttling function is obtained by injection molding through a mold. The quick-connect joint structure is composed of the combination of the quick-connect female joint 1 and the throttling structure 2, and the sealing ring 3 is sleeved on the outside of the quick-connect female joint 1. When the quick-connect male joint 5 is docked with the quick-connect female joint 1, the quick-connect male joint 5 is inserted from the bottom of the quick-connect female joint 1 until it abuts tightly. The sealing ring 3 ensures the sealing between the quick-connect female joint 1 and the quick-connect male joint 5. In addition, when the quick-connect male joint 5 is inserted and abuts tightly, the locking spring 4 on the body of the quick-connect female joint 1 is buckled into the connecting boss at the top of the quick-connect male joint 5. Thus, the assembly of the quick-connect female joint 1 and the quick-connect male joint 5 is completed, and the annular anti-detachment structure at the front end of the shell of the quick-connect female joint 1 is used to connect and fix the hose.

[0030] The quick-connect joint with a throttling function formed by the combination of the quick-connect male joint 1 and the throttling structure 2 can be integrally injection molded through a mold, thereby reducing the cost of manual assembly and avoiding the risk of missing installation of the throttle valve. In addition, the mold can produce throttling quick-connects and conventional quick-connects through the replacement of sliders, reducing the production cost.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
