Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a novel snap-fit ​​interface. Background Technology

[0002] In fields such as fire rescue and industrial water supply, snap-fit ​​quick-connect couplings are commonly used to enable rapid connection and disconnection of pipelines. Existing snap-fit ​​couplings, such as those used on fire sprinkler systems or water stoppers, are shown in the attached image. Figure 1 As shown, its locking mechanism typically consists of a rotatable operating ring (or locking wheel), a separate slider base, and a slider that can slide on the base. In this structure, the operating ring and the slider base are two independent parts, which are machined separately during production and then assembled together. However, this split-type structural design has inherent defects. First, the operating ring and the slider base inevitably produce shape and position tolerances such as flatness and parallelism during their respective machining processes; second, assembling these two independent parts introduces new assembly errors. The accumulation of these machining tolerances and assembly errors directly affects the smoothness of the slider's sliding on the slider base, and in severe cases, may even cause the slider to jam during movement. This may prevent the interface from opening smoothly and promptly when emergency unlocking is required, posing a safety hazard. In addition, the mating gaps created by this split structure may also cause the female interface to become unstable after being connected to the male interface due to vibrations in the field or the impact of high-pressure water flow in the pipeline, posing a risk of accidental detachment and thus affecting the safety and reliability of the entire pipeline system. Utility Model Content

[0003] The purpose of this utility model is to provide a novel snap-fit ​​interface that solves the technical problems of accumulated processing and assembly errors caused by the separate design of the operating ring and the slider guide structure in existing snap-fit ​​interfaces, which leads to slider slippage, difficulty in unlocking, and unstable connection. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The novel snap-fit ​​interface provided by this utility model includes an interface body, an operating ring disposed on the interface body, and a slider disposed slidably inside the operating ring.

[0006] A guide structure is fixedly provided inside the operating ring; the slider is slidably disposed on the guide structure, and the guide structure is used to guide the slider to slide toward or away from the axis of the interface body.

[0007] Preferably, the operating ring has an L-shaped cross-section, and the guide structure is disposed on the short side of the L-shaped structure.

[0008] Preferably, the guide structure is an arc-shaped sheet.

[0009] Preferably, there are multiple guide structures arranged along the circumference of the operating ring, and two adjacent guide structures, the inner wall of the operating ring, and the end wall of the interface body form a sliding hole, and the slider is slidably disposed in the sliding hole.

[0010] Preferably, the operating ring and the guide structure are integrally formed.

[0011] Preferably, the operating ring and the guide structure are formed by machining, casting, or additive manufacturing.

[0012] Preferably, the operating ring and the guide structure are welded together.

[0013] Preferably, the operating ring and the guide structure are made of aluminum alloy.

[0014] The application employs the above technical solution and has at least the following beneficial effects:

[0015] The new snap-fit ​​interface includes an interface body, an operating ring disposed on the interface body, and a slider disposed inside the operating ring. A guide structure is fixedly disposed inside the operating ring. The slider is slidably disposed on the guide structure, which guides the slider to slide toward or away from the axis of the interface body. In this way, the fixed setting of the operating ring and the guide structure reduces assembly errors, thereby solving the problems of sliding jamming and poor unlocking during connection, as well as the technical problem of unstable connection.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] A specific embodiment of this utility model provides a novel snap-fit ​​interface, which aims to fundamentally solve the performance defects caused by the split design of the prior art from a structural perspective.

[0023] To facilitate understanding of the technical advantages of the embodiments of this application, the prior art will be described first. Figure 1 An exploded view of a typical snap-fit ​​interface in the prior art is shown. Figure 1 As shown, traditional locking mechanisms typically consist of at least three core, independent components: an operating ring 2 for user rotation, a separately manufactured slider base (guide structure 4), and a slider 3 mounted on the guide structure 4. The guide structure 4 supports the slider 3 and defines its movement trajectory. In this split design, the operating ring 2 and the guide structure 4 are two separate parts, each with independent shape and positional tolerances (e.g., flatness, parallelism errors) generated during their respective manufacturing processes. Furthermore, new assembly errors are introduced when they are fixed together. The accumulation of these errors from different components and processes results in an uneven sliding path for the slider 3 on the guide structure 4, increased frictional resistance, and in severe cases, even jamming or seizing. Such malfunctions pose serious safety hazards in situations requiring rapid connection or emergency unlocking, such as fire rescue operations. Moreover, the assembly gaps between components reduce the overall rigidity of the structure, potentially leading to loosening of connections under water pressure or external vibration, also posing a safety hazard.

[0024] To overcome the above-mentioned shortcomings, this application proposes an innovative structural design. (See attached...) Figure 2 As shown, it is a cross-sectional structural diagram of a novel snap-fit ​​interface provided in this application, and... Figure 1 Compared to the split structure shown, the structure of this embodiment is significantly simplified, including an interface body 1, an operating ring 2 disposed on the interface body 1, and a slider 3 slidably disposed inside the operating ring 2.

[0025] Furthermore, a guide structure 4 is fixedly installed inside the operating ring 2; the slider 3 is slidably mounted on the guide structure 4, which is used to guide the slider 3 to slide towards or away from the axis of the interface body 1.

[0026] The fixed arrangement of the operating ring 2 and guide structure 4 makes them physically form a continuous, seamless single component. This design completely eliminates the assembly interface between the roller and the slider base in the traditional structure, thereby fundamentally eliminating the problem of assembly errors and tolerance accumulation between the two, reducing assembly errors, and thus solving the problems of sliding jamming and poor unlocking during connection, as well as the technical problem of unstable connection.

[0027] In a specific embodiment of this application, the operating ring 2 and the guide structure 4 are integrally formed. For example, they can be manufactured in one piece using the same raw material (such as a metal billet) through casting, forging, or preferably by machining (such as milling or turning). Of course, they can also be manufactured using other additive manufacturing (3D printing) methods.

[0028] Of course, the operating ring 2 and the guide structure 4 can also be welded together to form a whole.

[0029] In some embodiments, the operating ring 2 and the guide structure 4 can be made of aluminum alloy, specifically high-strength aluminum alloy.

[0030] In some embodiments, as shown in the appendix Figure 2 As shown, the cross-section of the operating ring 2 is an L-shaped structure, and the guide structure 4 is set on the short side of the L-shaped structure. The end of the operating ring 2 away from the short side is connected to the interface body 1, and one end of the guide structure 4 is connected to the short side, while the other side extends toward the interface body 1.

[0031] Specifically, the guide structure 4 is an arc-shaped sheet. Furthermore, there are multiple guide structures 4, which are evenly arranged inside the operating ring 2 and along its circumference. Thus, two adjacent guide structures, the inner wall of the operating ring 2, and the end wall of the interface body 1 form a sliding hole, and the slider 3 is slidably arranged in the sliding hole.

Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
