Description

Technical Field

[0001] This utility model relates to the field of air tube connector technology, specifically to a quick-connect connector mechanism. Background Technology

[0002] Quick-connect couplings are the most convenient plug-and-play connection method, especially advantageous in situations where air pipe connections are inconvenient or in difficult spaces. Quick-connect couplings are components used for quickly connecting / disconnecting pneumatic, hydraulic, or fluid lines, and are widely used in industrial automation, automotive, and medical equipment industries.

[0003] Existing C-type tracheal connectors or quick-connect connectors used to lock the trachea have an internal two barbed, pointed, straight-opening structure. This straight-opening design allows the trachea to pass vertically through after opening, which can easily cause several C-type tracheal connectors to clump together and become entangled during the manufacturing process and assembly.

[0004] When the traditional aluminum connector body 1' is used with a C-type gas hose connector (i.e., a traditional quick-connect connector 7) (refer to...) Figure 1 An auxiliary plastic plug 4 is needed to position the traditional quick-connect fitting 7 and the traditional aluminum fitting body 1' to prevent the quick-connect fitting from falling off the aluminum fitting body. The plastic plug 4 is then removed during subsequent pipe installation. However, this installation method adds the plastic plug as an accessory for auxiliary positioning, which increases the cost. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to solve the problems of existing air pipe connectors having clumps and entanglements, and the need to add auxiliary accessories when connecting them to the aluminum connector body.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A quick-connector mechanism includes an aluminum connector body and an air pipe connector installed at one end thereon. A boss for fixing the air pipe connector is provided at the end of the aluminum connector body. An irregular groove for disconnecting the air pipe connector is provided on the air pipe connector.

[0008] This application features a protrusion at one end of the aluminum connector body, which can be used to fix the air pipe connector. This eliminates the need for a separate plastic plug to ensure the connection between the aluminum connector body and the air pipe connector. At the same time, the air pipe connector has a shaped groove, which can prevent several air pipe connectors from tangling and clumping together when they are piled up. The opening cross-sectional area of ​​the new air pipe connector is larger than that of the original straight C-shaped connector, resulting in less force when inserting the pipe. When the pipe is pulled outward, the new air pipe connector is in contact with all four sides of the pipe, making the locking force more stable.

[0009] As a further embodiment of this invention, the irregular groove adopts a stepped structure.

[0010] As a further embodiment of this utility model, the irregular groove adopts a "Z" shaped structure.

[0011] As a further embodiment of this utility model: the tracheal connector includes an annular portion and a conical portion designed in one piece.

[0012] As a further embodiment of this utility model, the outer ring of the annular portion is provided with an adjustment notch.

[0013] As a further embodiment of this utility model: the adjustment incision is a horizontal incision or a concave incision.

[0014] As a further embodiment of this utility model: the adjustment cut and the irregular groove are symmetrically arranged.

[0015] As a further embodiment of this utility model: the inner wall of the tracheal connector is provided with at least one ring of inwardly protruding locking blocks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application provides a protrusion at one end of the aluminum connector body, which can be used to fix the air pipe connector. The connection between the aluminum connector body and the air pipe connector can be guaranteed without the need to add a separate plastic plug. When the air pipe connector is subjected to force, its outer diameter will decrease and it will be inserted into the connector body. After the external force is removed, the air pipe connector will return to its original shape and be stuck by the protrusion on the connector body, so it cannot be detached. At this time, it is not necessary to use the original plastic for fixation, thereby reducing the use of accessories and thus reducing costs.

[0018] 2. This application provides irregularly shaped grooves, such as trapezoidal or Z-shaped grooves, on the tracheal connectors to prevent them from tangling and clumping together when several tracheal connectors are stacked.

[0019] 3. The new type of endotracheal connector has a larger opening cross-sectional area than the original straight C-shaped connector, which requires less force when inserting the pipe, thus reducing the insertion force. When the pipe is pulled outward, the new type of endotracheal connector is in contact with all four sides of the pipe, resulting in a more stable locking force. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0032] Reference Figure 2 A quick-connect coupling mechanism includes an aluminum connector body 1 and an air pipe connector 6 installed at one end of the aluminum connector body 1. A protrusion 101 is provided on the inner side of the end of the aluminum connector body 1, which can support and fix the aluminum connector body 1. A sealing ring 3 5 is sleeved on the outside of the aluminum connector body 1, and a sealing ring 1 and a sealing ring 2 3 are sleeved on the inside, for subsequent connection of pipes (generally plastic pipes).

[0033] Reference Figure 3 and Figure 4The tracheal connector 6 includes an annular portion 601 and a conical portion 602, wherein the conical portion 602 is located on one side of the annular portion 601 and the two are integrally formed. The inner wall of the aluminum connector body 1 that contacts the annular portion 601 and the conical portion 602 is provided with a conical connecting portion and an annular connecting portion to ensure that the outer wall of the tracheal connector 6 can fit tightly against the inner wall of the aluminum connector body 1.

[0034] Reference Figure 4 and Figure 5 The tracheal connector 6 has a shaped groove 603, which can disconnect the tracheal connector 6. The shaped groove 603 can adopt a double trapezoidal design (e.g., Figure 4 , Figure 5 and Figure 6 Alternatively, a "Z" shape design can be used (such as...). Figure 7 and Figure 8 Various shapes may be used depending on the actual situation, and this application does not limit them. The irregular shape design can prevent multiple air pipe connectors 6 from getting tangled and clumped together when stacked.

[0035] Furthermore, an adjustment notch 604 is provided on the tracheal connector 6 at a position symmetrical to the irregular groove 603. The adjustment notch 604 can be a horizontal notch or a concave notch. This application adds an adjustment notch 604 symmetrical to the opening of the irregular groove, so that when the tracheal connector 6 grips the plastic tube, the force is even, thereby preventing uneven force on the plastic tube during cutting and causing the plastic tube to fall off. In addition, the setting of the adjustment notch 604 allows a certain space to be left between the tracheal connector 6 and the inner side of the aluminum connector body 1 for the installation of the tracheal connector 6 and subsequent removal.

[0036] Reference Figure 6 The inner wall of the tracheal connector 6 is provided with at least one ring of inwardly protruding locking blocks (i.e. barbs). When the plastic tube is inserted into the aluminum connector body 1 and the tracheal connector 6, the locking block design can ensure that it is locked with the plastic tube, so that it can be tightly connected to the plastic tube.

[0037] When the traditional aluminum connector body 1' is used with the traditional quick-connect connector 7, an auxiliary plastic plug 4 is required to position the traditional quick-connect connector 7 and the traditional aluminum connector body 1' to prevent the quick-connect connector from falling off the aluminum connector body. The plastic plug 4 is then removed during subsequent pipe installation. Based on this, this application designs a new aluminum connector body 1 and a new air pipe connector 6, which can achieve positioning of the two without adding the plastic plug 4.

[0038] The specific operating principle of this application is as follows:

[0039] When not in use, several tracheal connectors 6 are stacked together. Because the tracheal connectors 6 are provided with irregular grooves 603, the tracheal connectors 6 can be prevented from tangling and clumping together.

[0040] When in use, the air pipe connector 6 can be retracted into the aluminum connector body 1. Then the air pipe connector 6 will no longer be forced open and will press against the inner wall of the aluminum connector body 1. The protrusion 101 on the aluminum connector body 1 will lock the air pipe connector 6 in place. Then, the plastic tube (not the traditional plastic plug 4, but the pipe required for installation) is inserted. The design of the irregular groove structure can make the force more even when the plastic tube is inserted and pulled out. The opening of the air pipe connector 6 of the irregular groove crosses and narrows to press the plastic tube, and the pressure is uniform and firm and reliable.

[0041] When the plastic tube is inserted, the Z-shaped and trapezoidal opening of the air tube connector 6 has a larger opening cross-sectional area than the original straight quick-connect connector, resulting in less insertion force. When the plastic tube is pulled out, the Z-shaped and trapezoidal opening of the air tube connector 6 is in contact with all sides of the plastic tube, making the locking force more stable. An adjustment slit 604 is added opposite the irregular groove 603 to prevent the air tube connector 6 from locking with the aluminum connector body 1 when it is tightened, and it can be reused.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions 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 this utility model.
