Description

Technical Field

[0001] This utility model belongs to the field of straight connectors, and relates to a straight connector, and particularly to a quick-release straight connector. Background Technology

[0002] Straight connectors are connecting fittings in piping systems. When connecting hoses, straight connectors require threads on their surface for sealing purposes. However, when the hose needs to be removed, due to the good sealing, a large amount of pressure needs to be applied along the hose axis to remove it. This can easily damage the hose, reduce operational efficiency, and increase usage costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a quick-release straight connector.

[0004] The objective of this utility model can be achieved through the following technical solution: A quick-release straight connector, comprising a connector body, characterized in that the connector body is provided with an upper connecting part and a threaded pipe post, a locking mechanism is provided on the inner wall of the upper connecting part, an active space I for the locking mechanism to move on the upper connecting part, the locking mechanism including a locking block and a locking spring, a sealing element is provided on the locking block, a sealing protrusion is provided on the sealing element, anti-slip protrusions are provided on both sides of the locking block relative to the sealing element, an unlocking element is provided on the inner wall of the upper connecting part, a limiting part is provided on the unlocking element, an active space II for the limiting part to move on the upper connecting part, and a return spring is provided in the active space II relative to the limiting part below.

[0005] In the aforementioned quick-release straight connector, a guide portion is provided at the lower end of the locking block.

[0006] In the aforementioned quick-release straight connector, an installation part is provided between the threaded pipe and the connector body, the installation part is provided with a V-groove, and a sealing ring is provided on the V-groove.

[0007] Compared with the prior art, this utility model makes it easier and less strenuous to assemble and disassemble the upper connecting part and the hose through the locking mechanism and unlocking key, and the sealing element on the locking block provides a better seal between the hose and the upper connecting part.

Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this quick-release straight connector includes a connector body 1, an upper connecting part 2 and a threaded tube post 3 on the connector body 1, a locking mechanism 4 on the inner wall of the upper connecting part 2, and an active space 5 on the upper connecting part 2 for the locking mechanism 4 to move. The locking mechanism 4 includes a locking block 6 and a locking spring 7. A sealing element 8 is provided on the locking block 6, and a sealing protrusion 9 is provided on the sealing element 8. When the hose is squeezed in, a resistance is generated to make the sealing and connection strength stronger. Anti-slip protrusions 10 are provided on the locking block 6 on both sides relative to the sealing element 8. An unlocking element 11 is provided on the inner wall of the upper connecting part 2, and a limiting part 12 is provided on the unlocking element 11. An active space 23 is provided on the upper connecting part 2 for the limiting part 12 to move, and a return spring 14 is provided in the active space 23 relative to the lower part of the limiting part 12.

[0013] To elaborate further, a guide portion 15 is provided at the lower end of the locking block 6.

[0014] To elaborate further, an installation part 16 is provided between the threaded pipe column 3 and the connector body 1. A V-groove 17 is provided on the installation part 16, and a sealing ring 18 is provided on the V-groove 17.

[0015] Working principle: During installation, the hose is inserted and squeezed into the upper connecting part 2. The hose contacts the anti-slip protrusion 10 of the locking block 6, and then touches the sealing protrusion 9 of the sealing element 8. When the sealing protrusion 9 contacts the hose, it generates a resistance, making the seal and connection stronger. Then it reaches the guide part 15, which further squeezes the hose inward to make the connection more secure. During disassembly, press the unlocking part 11, which presses the locking block 6 into the movable space 5, so that the unlocking part 11 loses its restraining force on the hose, allowing the hose to be easily removed.

[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as connector body 1, upper connecting part 2, threaded pipe column 3, locking mechanism 4, first movable space 5, locking block 6, locking spring 7, sealing element 8, sealing protrusion 9, anti-slip protrusion 10, unlocking element 11, limiting part 12, second movable space 13, return spring 14, guide part 15, mounting part 16, V-groove 17, and sealing ring 18, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
