Description

Technical Field

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

[0002] Firefighting connections, such as hose connections, include male connectors, female connectors, and snap-fit ​​connectors. Hose with male or female connectors cannot be connected to hoses with snap-fit ​​connectors; conversely, hoses with snap-fit ​​connectors cannot be connected to hoses with either male or female connectors. A universal connection is not possible. Utility Model Content

[0003] This utility model addresses one of the problems existing in the prior art to a certain extent. Therefore, one objective of this utility model is to provide a quick connector that facilitates the connection between hoses with male connectors and hoses with snap-fit ​​interfaces, avoiding the problem of incompatibility due to different hose interface types.

[0004] The above objective is achieved through the following technical solution:

[0005] A quick connector has a cavity with an installation port at one end formed in the connector body, and a female connector and a snap-fit ​​connector are provided on the connector body.

[0006] The female connector is located at the end away from the mounting port. The female connector includes a first stepped portion and a connecting spring piece. A first mounting position is formed between the first stepped portion and the connecting spring piece. The first mounting position is used to mate with the male connector for connection.

[0007] The snap-fit ​​connection part includes a second stepped part and an abutting part at one end near the mounting port, and a second mounting position is formed between the second stepped part and the abutting part. The second mounting position is used to cooperate with the snap-fit ​​interface for connection.

[0008] As a further improvement of this utility model, the connecting spring is installed on the inner wall of the cavity and extends towards the cavity. The connecting spring can contract towards the inner wall of the cavity to undergo elastic deformation. When the connecting spring contracts towards the inner wall of the cavity, a first installation channel is formed between the mounting opening and the connecting spring. The male connector can extend into the first mounting position through the first installation channel.

[0009] As a further improvement of this utility model, a stop surface is formed at the end of the connecting spring piece away from the mounting port. When the mounting edge of the male connector is installed in the first mounting position, the stop surface abuts against the mounting edge to prevent the male connector from disengaging from the cavity.

[0010] As a further improvement of this utility model, an inclined slope is formed at one end of the connecting spring piece near the mounting port. When the male connector extends from the mounting port into the first mounting position, the mounting edge and the inclined slope act to retract the connecting spring piece toward the inner wall of the cavity.

[0011] As a further improvement of this utility model, the abutting parts are circumferentially spaced within the cavity, and a second channel is formed between adjacent abutting parts. The hook of the fastening connector extends into the second mounting position through the second channel and abuts against the second step.

[0012] As a further improvement of this utility model, when the hook is inserted into the second mounting position, the female connector is rotated to abut against the abutment portion, thereby preventing the fastening connector from disengaging from the cavity.

[0013] As a further improvement of this utility model, a fastening part is formed by extending outward from the connector body, and an extension edge is formed by extending inward from the fastening joint, wherein the fastening joint and the extension edge are fastened together.

[0014] As a further improvement of this utility model, a third step portion is formed at the fastening joint, a third mounting position is formed between the third step portion and the extended edge, a gap is formed at the extended edge, and the fastening portion extends into the third mounting position through the gap and abuts against the third step portion.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] This invention proposes a quick connector that integrates a female connector and a snap-fit ​​connector into a single quick connector. A hose with a snap-fit ​​connector can be connected to a male connector after being connected to the quick connector; conversely, a hose with a male connector can be connected to a snap-fit ​​connector after being connected to the quick connector. This facilitates the connection between hoses with male connectors and hoses with snap-fit ​​connectors, avoiding connection problems caused by different hose connector types.

[0027] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0028] like Figure 1-10 A quick connector includes a connector body 1, a cavity 12 having an installation port 11 at one end is formed in the connector body 1, and a female connector 2 and a snap-fit ​​connector 3 are provided on the connector body 1.

[0029] The female connector 2 is located at the end away from the mounting port 11. The female connector 2 includes a first stepped portion 21 and a connecting spring piece 22. A first mounting position 23 is formed between the first stepped portion 21 and the connecting spring piece 22. The first mounting position 23 is used to mate with the male connector 4 for connection.

[0030] The snap-fit ​​connection part 3 is located at one end near the mounting port 11. The snap-fit ​​connection part 3 includes a second step part 31 and an abutment part 32. A second mounting position 33 is formed between the second step part 31 and the abutment part 32. The second mounting position 33 is used to cooperate with the snap-fit ​​interface 5 for connection.

[0031] This invention proposes a quick connector that integrates a female connector 2 and a snap-fit ​​connector 3 into a single quick connector. A hose with a snap-fit ​​interface 5 can be connected to a male connector 4 after being connected to the quick connector; similarly, a hose with a male connector 4 can be connected to a snap-fit ​​interface 5 after being connected to the quick connector. This facilitates the connection between hoses with male connectors 4 and hoses with snap-fit ​​interfaces 5, avoiding connection problems due to different hose interface types.

[0032] The connecting spring 22 is installed on the inner wall of the cavity 12 and extends toward the cavity 12. The connecting spring 22 can contract toward the inner wall of the cavity 12 to undergo elastic deformation. When the connecting spring 22 contracts toward the inner wall of the cavity 12, a first installation channel is formed between the mounting port 11 and the connecting spring 22. The male connector 4 can extend into the first mounting position 23 through the first installation channel.

[0033] In this embodiment, the first stepped portion 21 is located at the end away from the mounting port 11, and the connecting spring piece 22 is located at the end close to the mounting port 11.

[0034] The connecting spring 22 can retract towards the inner wall of the cavity 12, and is in a retracted state; the connecting spring 22 can also extend away from the inner wall of the cavity 12, and is in an extended state. Under normal conditions, the connecting spring 22 is in an extended state, and when the connecting spring 22 is compressed and retracted, it undergoes elastic deformation and is in a retracted state.

[0035] A stop surface 221 is formed at the end of the connecting spring 22 away from the mounting port 11. When the mounting edge 40 of the male connector 4 is installed in the first mounting position 23, the stop surface abuts against the mounting edge 40 to restrict the male connector 4 from disengaging from the cavity 12.

[0036] An inclined surface 222 is formed at one end of the connecting spring 22 near the mounting port 11. When the male connector 4 extends from the mounting port 11 into the first mounting position 23, the mounting edge 40 and the inclined surface 222 act to retract the connecting spring 22 toward the inner wall of the cavity 12, so that the connecting spring 22 is retracted and the mounting edge 40 can smoothly enter the first mounting position 23 through the first mounting channel.

[0037] In this embodiment, the cross-section of the connecting spring 22 gradually increases from the end near the mounting port 11 to the end away from the mounting port 11. The cross-section of the connecting spring 22 is triangular.

[0038] In this embodiment, the connecting spring pieces 22 are circumferentially spaced on the inner wall of the cavity 12; the mounting edge 40 is circumferentially arranged at the bottom of the male connector 4.

[0039] A pressure plate 41 is provided at the male connector 4, and the pressure plate 41 is sleeved on the male connector 4. When the male connector 4 needs to be removed from the cavity 12 of the quick connector, the pressure plate 41 presses down and acts on the connecting spring 22, so that the connecting spring 22 contracts and undergoes elastic deformation. At this time, the male connector 4 can be removed from the installation port 11 through the first installation channel, that is, the male connector 4 can be separated from the cavity 12.

[0040] The abutting portions 32 are circumferentially spaced within the cavity 12, and a second mounting channel 34 is formed between adjacent abutting portions 32. The hook 51 of the fastening interface 5 extends into the second mounting position 33 through the second mounting channel 34 and abuts against the second step portion 31.

[0041] In this embodiment, the second stepped portion 31 is located at the end away from the mounting port 11, and the abutting portion 32 is located at the end close to the abutting portion 32.

[0042] When the hook 51 extends into the second mounting position 33, the hook 51 is abutted against the abutting part 32 by rotating the fastening interface 5, thus preventing the fastening interface 5 from disengaging from the cavity 12.

[0043] In this embodiment, when the snap-fit ​​connection part 3 is connected to the quick connector, the hook 51 abuts against or snaps into the abutment part 32.

[0044] A fastening portion 14 extends outward from the connector body 1, and an extension edge 54 extends inward from the fastening interface 5. The fastening portion 14 and the extension edge 54 are fastened together.

[0045] A third step portion 53 is formed at the fastening interface 5, a third mounting position 55 is formed between the third step portion 53 and the extended edge 54, a gap 56 is formed at the extended edge 54, and the fastening portion 14 extends into the third mounting position 55 through the gap 56 and abuts against the third step portion 53.

[0046] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
