DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figure 1 、 Figure 2 、 Figure 3 As shown, the utility model is a quick-install connection structure between an inner and outer dual-channel hose, including a quick-install clamp 1, the quick-install clamp 1 is fixedly installed with two sections of quick-install connectors 2, one section of the quick-install connector 2 is installed with an inner tube fixing frame male head 3, and the other section of the quick-install connector 2 is installed with an inner tube fixing frame female head 4, and both the inner tube fixing frame male head 3 and the inner tube fixing frame female head 4 are provided with through holes 41;

[0025] An inner tube male connector 5 is installed at the center axis of the inner tube fixing frame male connector 3, and an inner tube female connector 6 is installed at the center axis of the inner tube fixing frame female connector 4. The inner tube male connector 5 is plugged into the inner tube female connector 6.

[0026] The quick connector 2, the inner tube male connector 5 and the inner tube female connector 6 are all provided with a crimping groove 7, and the crimping groove 7 is matched with a crimping tube 8. The crimping groove 7 on the quick connector 2 is crimped and connected to the outer layer heat-insulating hose 9 through the crimping tube 8, and the crimping groove 7 on the inner tube male connector 5 and the inner tube female connector 6 is crimped and connected to the inner layer hose 10 through the crimping tube 8.

[0027] In this embodiment, the inner tube male connector 5 is first installed in the inner tube fixing frame male connector 3. The installation of the two can be detachable or fixed. Similarly, the inner tube female connector 6 is also installed in the inner tube fixing frame female connector 4.

[0028] Then, use a crimping tool to crimp the inner hose 10 into the crimping groove 7 through the crimping tube 8. After the inner hoses 10 on the inner tube male connector 5 and the inner tube female connector 6 are crimped and installed, place the inner tube fixing frame male head 3 and the inner tube fixing frame female head 4 inside the two sections of quick-release connectors 2 to be connected, and then use the quick-release clamp 1 to fix the two sections of quick-release connectors 2. When the two sections of quick-release connectors 2 are docked, the inner tube male connector 5 and the inner tube female connector 6 are plugged in due to the position limitation, thereby realizing the communication of the inner layer hoses 10 connected to each other;

[0029] Insert the outer thermal insulation hose 9 from the end of the inner layer hose 10 until the end is placed in the crimping groove 7, and then use the crimping tool and the crimping tube 8 to connect the outer thermal insulation hose 9 to the quick connector 2, thereby achieving the communication between the outer thermal insulation hoses 9 connected respectively. Under the effect of the through hole 41, the flow of the medium between the outer thermal insulation hose 9 and the inner layer hose 10 will not be affected, ensuring the diversity of use;

[0030] Furthermore, under this structure, the inner hose 10 can be completely disassembled, so the outer insulation hose can also be used as a conventional single-channel hose, which has a wider range of applicable scenarios and low replacement and maintenance costs.

[0031] Example 2:

[0032] like Figure 3 As shown, an O-ring 11 is installed at the plugging position of the inner tube male connector 5 and the inner tube female connector 6. This design ensures sealing.

[0033] In this embodiment, the sealing method adopts O-ring, but it is not limited to the use of sealing rings. Other sealing methods can be used, and the number of O-rings 11 is not limited to ensure the sealing effect.

[0034] Example 3:

[0035] like Figure 3 As shown, the end of the quick connector 2 is integrally formed with a frustum 12, and a silicone sealing gasket 13 is installed between the two quick connectors 2. This design facilitates cooperation with the quick clamp 1, and under the effect of the frustum 12, the two quick connectors 2 have the function of self-positioning, and the silicone sealing gasket 13 enhances the sealing effect;

[0036] In this embodiment, the cone 12 mainly relies on its slope to guide positioning. The size of the slope is not limited. Furthermore, the sealing method after the two are connected is also not limited. A silicone sealing pad can be used as in this application, or a sealing ring can be used.

[0037] Example 4:

[0038] like Figure 3 As shown, a limit retaining ring 14 is installed inside the quick connector 2. This design limits the position of the inner tube fixing frame male head 3 and the inner tube fixing frame female head 4, and has a good anti-pull effect;

[0039] In this embodiment, the fixing of the limit retaining ring 14 adopts a concave-convex fit, that is, a groove is provided at the corresponding position of the quick-release connector 2. When the limit retaining ring 14 is in the position of this groove, the position of the limit retaining ring 14 is limited. Further explanation, the limit retaining ring 14 is a retaining ring with an opening, so that the limit retaining ring 14 can be deformed, which is more conducive to being stuck in the groove.

[0040] Embodiment 5:

[0041] like Figure 3 As shown, the length of the buckling groove 7 and the buckling tube 8 supports at least three buckling teeth. This design ensures the strength of the buckling connection;

[0042] In this embodiment, the formation of the crimping teeth relies on the corresponding crimping tools, which can be directly purchased in the existing technology, so the crimping tube 8 only needs to adapt to the working length of the crimping tool. Accordingly, the more crimping teeth there are, the stronger the connection.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
