Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a high-strength quick-connect coupling for automotive hydraulic systems. Background Technology

[0002] The schematic diagram of the existing quick-connect connector is as follows: Figure 1 As shown: The mechanism mainly consists of a rubber sleeve a, a movable core b, an outer shell c, a rubber ring d, a rubber spring pad e, a spring f, a rubber ring g, and a rubber ring h. When not in use, the rubber sleeve a serves to isolate foreign objects and maintain cleanliness. The rubber rings d, h, and g provide a connection and seal. The rubber spring pad e supports the spring f and holds the movable core b against it. The rubber ring g and the outer shell c are press-fitted together to provide a seal.

[0003] The above-mentioned quick-connect fittings have the following disadvantages, such as Figure 1 As shown:

[0004] (1) For high-intensity hydraulic (gas) pressure, the rubber spring pad e cannot support the pressure (30MPa) applied to the accessories and will fall off and lose its proper function;

[0005] (2) The springs in the existing products cannot support the corresponding force (30MPa) and cannot play a sealing role;

[0006] (3) The active core b has a long processing time, complicated processing technology and high cost during the production process. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this application proposes a high-strength quick-connect coupling for automotive hydraulic systems to solve the problems existing in the prior art.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A high-strength quick-connect coupling for an automotive hydraulic system includes a housing, a movable core, a rubber ring, and a spring.

[0010] As a further technical solution of this utility model: the spring is a high-strength metal spring with an elastic coefficient that meets the reset requirement under a pressure of 30MPa.

[0011] As a further technical solution of this utility model: the movable core is an integrally molded structure.

[0012] As a further technical solution of this utility model: the rubber ring is made of fluororubber with a temperature resistance range of -40℃ to 150℃.

[0013] As a further technical solution of this utility model: the outer shell is also provided with rubber ring two and rubber ring three.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] This invention solves the problems of easy failure under high pressure and high processing cost of existing products. The connector can withstand pressures exceeding 30MPa and is suitable for quick connection and reliable sealing of automotive fuel systems. Attached Figure Description

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 2As shown, a high-strength quick-connect coupling for an automotive hydraulic system includes a housing C, a movable core B, rubber rings D and G, and a spring F. The spring F is a high-strength metal spring with an elastic coefficient that meets the reset requirement under 30 MPa pressure. The movable core B and housing C are sealed by an interference fit with the rubber ring D. A threaded washer E is provided inside the housing C to fix the spring F and withstand axial force. The movable core B is manufactured using an integrated molding process, reducing processing steps. The rubber ring D is made of fluororubber with a temperature resistance range of -40℃ to 150℃. Additionally, the housing C also contains rubber rings G and H.

[0024] When in use, remove the rubber sleeve (for dust protection), install the fitting, and apply a force to the fitting that is greater than the force of the spring. The moving core moves toward the threaded pad, and the rubber ring separates from the interference point of the outer shell to form a passage.

[0025] Remove the accessories. With no external force applied to the movable core, the spring's elasticity will cause the movable core to spring up, and the rubber ring and outer shell will fit together to form a closed circuit.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
