Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a rotary disassembly connector. Background Technology

[0002] In the field of mechanical connections, rotary disassembly joints, with their unique ease of operation and high efficiency, have become an indispensable key component in industrial production, widely used in piping systems, modular equipment assembly, and various scenarios requiring rapid disassembly and assembly. Mechanical connections, as a fundamental aspect of industrial equipment operation, involve multiple fields such as hydraulic systems, pneumatic systems, fluid transmission pipelines (e.g., water pipes, oil pipes, air pipes), and modular assembly of mechanical equipment. These scenarios place stringent requirements on the reliability, disassembly and assembly efficiency, and ease of operation of connection methods. Traditional connection methods (such as threaded connections and flange connections) typically require tools for tightening or loosening, which is time-consuming and prone to loosening or seal failure due to uneven force. This inefficiency is particularly pronounced in scenarios requiring frequent disassembly and assembly (e.g., equipment debugging, maintenance, and component replacement). The emergence of rotary disassembly joints effectively solves this problem. Their core advantage lies in achieving rapid disassembly and assembly through a simple rotational motion: operators only need to manually rotate the movable external joint to disengage the snap-fit ​​structure, eliminating the need for additional tools and significantly reducing labor intensity, making them particularly suitable for confined spaces or scenarios requiring one-handed operation.

[0003] Existing rotary disassembly joints have significant design flaws. Their movable outer connectors are typically circular, requiring manual pressing to extend the extension rod outwards and disengage it from the retaining ring at the outer edge of the mounting joint. Because extending the extension rod requires overcoming considerable resistance during pressing, operators often resort to prying the connector with tools due to insufficient force. This non-standard operation easily leads to uneven stress on the movable outer connector, causing it to break and resulting in overall joint failure. This not only increases equipment maintenance costs but also poses safety hazards. Therefore, a rotary disassembly joint is needed to address this problem. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rotary disassembly connector. This rotary disassembly connector features a stepped inclined support surface on the outer edge of the blocking ring, with the extension rod positioned at the lowest point of the inclined support surface. During disassembly, rotating the movable outer connector causes the extension rod to move along the inclined support surface. The stepped structure gradually guides the extension rod to open outward, avoiding impact or damage caused by sudden opening. At the same time, the inclined support surface provides stable support for the extension rod, ensuring a smooth disassembly process.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a rotary disassembly connector, which includes an installation connector and an inner connector. An embedded retaining ring is provided on the outer side of the inner connector, and a movable outer connector is embedded in the embedded retaining ring. An extension rod is symmetrically provided on the movable outer connector, and a locking block is provided on the inner side of the extension rod. The mounting connector and the inner connector are inserted together. A snap-fit ​​ring is fitted and fixed on the outer edge of the mounting connector facing the inner connector. The snap-fit ​​ring is engaged with the snap-fit ​​block. A blocking ring is fitted and fixed on the outer edge of the inner connector and on the side facing the mounting connector to assist the movable outer connector. A support slope for the opening of the auxiliary extension rod is provided on the outer edge of the blocking ring.

[0006] Furthermore, the supporting inclined surface is generally a stepped inclined surface, and the extension rod is located at the lowest point of the supporting inclined surface.

[0007] Furthermore, a plurality of the embedded retaining rings are provided, and the plurality of embedded retaining rings are equidistantly arranged on the inner connector, and the embedded retaining rings are generally serrated.

[0008] Furthermore, the insertion end of the inner connector is conical, and the insertion end of the inner connector is inserted into the socket of the mounting connector.

[0009] Furthermore, a sealing groove is provided at the outer edge of the insertion end of the inner connector, and an elastic sealing gasket is embedded inside the sealing groove.

[0010] Furthermore, the two extension rods are connected by a connecting ring, which is C-shaped.

[0011] Furthermore, the outer edge of the movable outer connector is provided with anti-slip texture.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a stepped inclined surface on the outer edge of the blocking ring, with the extension rod positioned at the lowest point of the inclined surface. During disassembly, rotating the movable outer connector allows the extension rod to move along the inclined surface. The stepped structure gradually guides the extension rod to open outward, avoiding impact or damage caused by sudden opening. At the same time, the inclined surface provides stable support for the extension rod, ensuring a smooth disassembly process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This specific embodiment is a rotary disassembly connector, such as... Figure 1-5 As shown, the rotary disassembly connector includes an installation connector 1 and an inner connector 3. The installation connector 1 and the inner connector 3 are inserted together. The insertion end of the inner connector 3 is conical and is inserted into the insertion interface of the installation connector 1. A sealing groove 8 is provided at the outer edge of the insertion end of the inner connector 3. An elastic sealing gasket 9 is embedded in the sealing groove 8. The elastic sealing gasket 9 embedded in the sealing groove 8 at the outer edge of the insertion end of the inner connector 3 makes tight contact with the inner wall of the insertion interface of the installation connector 1, effectively preventing media leakage and improving the sealing performance of the connector.

[0018] An embedded retaining ring 4 protrudes from the outer side of the inner connector 3. A movable outer connector 5 is embedded in the retaining ring 4. An extension rod 6 protrudes symmetrically from the movable outer connector 5. The two extension rods 6 are connected by a connecting ring 7, which is C-shaped. The two extension rods 6 are connected by the C-shaped connecting ring 7. A locking block 61 protrudes from the inner side of the extension rod 6. A locking ring 2 is fitted and fixed at the outer edge of the end of the mounting connector 1 facing the inner connector 3. The locking ring 2 and the locking block 61 are engaged. The connecting ring 7 ensures that the two extension rods 6 move synchronously. When the movable outer connector 5 is rotated during disassembly, the two extension rods 6 can open outwards simultaneously, ensuring that the locking block 61 is evenly disengaged from the locking ring 2, avoiding jamming or damage caused by unilateral disengagement, and improving the stability and reliability of disassembly. The outer edge of the inner connector 3 and the side facing the installation connector 1 are fitted with a blocking ring 31 that is fixed to block the auxiliary movable outer connector 5. The outer edge of the blocking ring 31 is provided with a supporting inclined surface 32 for the auxiliary extension rod 6 to open. The supporting inclined surface 32 is a stepped inclined surface, and the extension rod 6 is located at the lowest point of the supporting inclined surface 32.

[0019] By making the supporting inclined surface 32 of the outer edge of the blocking ring 31 into a stepped inclined surface, and setting the extension rod 6 at the lowest point of the supporting inclined surface 32, during disassembly, rotating the movable outer connector 5 causes the extension rod 6 to move along the supporting inclined surface 32. The stepped structure can gradually guide the extension rod 6 to open outward, avoiding impact or damage caused by sudden opening. At the same time, the supporting inclined surface 32 provides stable support for the extension rod 6, ensuring the smooth progress of the disassembly process.

[0020] The outer edge of the movable outer connector 5 is provided with anti-slip texture. The anti-slip texture increases the friction between the operator's hand and the movable outer connector 5, making it easier to hold and rotate the movable outer connector 5 more firmly during disassembly or installation, and reducing the difficulty of operation.

[0021] Furthermore, several retaining rings 4 are provided, which are equidistantly arranged on the inner connector 3. The retaining rings 4 are generally serrated. By setting multiple retaining rings 4 and distributing them at equal intervals, and making them serrated, the multiple retaining rings 4 enhance the embedding stability between the movable outer connector 5 and the inner connector 3. The serrated structure increases the friction of the contact surface, preventing the movable outer connector 5 from accidentally sliding or falling off during use, and improving the overall structural stability. At the same time, the extra retaining rings 4 can effectively prevent the water pipe from loosening when connected to the water pipe later.

[0022] Working principle: During installation, align the conical insertion end of the inner connector 3 with the insertion interface of the mounting connector 1 and insert it. The conical structure acts as a guide, facilitating quick positioning and insertion, and reducing the difficulty of alignment during installation.

[0023] After the inner connector 3 is inserted, the retaining ring 4 on its outer edge is used to install the movable outer connector 5. The retaining block 61 on the inner side of the extension rod 6 on the movable outer connector 5 cooperates with the retaining ring 2 on the outer edge of the installation connector 1 to form a preliminary fixed connection.

[0024] The blocking ring 31 is sleeved on the outer edge of the inner connector 3 and faces the mounting connector 1. The supporting slope 32 opened on its outer edge is a stepped slope. The extension rod 6 is set at the lowest point of the supporting slope 32. The supporting slope 32 supports and guides the extension rod 6. When disassembly is required, the movable outer connector 5 is rotated and the extension rod 6 moves along the supporting slope 32. Due to the stepped structure of the supporting slope 32, the extension rod 6 gradually opens outward, causing the snap-fit ​​block 61 to disengage from the snap-fit ​​ring 2, thereby realizing the separation of the mounting connector 1 and the inner connector 3.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
