Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, and in particular to a press-fit connector for a fire hose bundle. Background Technology

[0002] In existing technology, fire water tanks are a basic public fire protection facility, containing fire hydrants, fire hoses, and sprinklers. During use, fire hoses need to be connected to fire hydrants and sprinklers, or multiple sections of fire hoses need to be connected. These sections are connected using hose couplings, which are typically secured to the hose with wire. However, connecting the hose to the coupling with wire results in poor fit at the connection point, making leakage more likely. Furthermore, due to the weak binding of the wire, during firefighting, the hose needs to be dragged forcefully to maintain firefighting speed, which can cause the wire at the hose-to-coupling connection to break or detach, thus affecting the progress of firefighting operations.

[0003] Chinese utility model patent application number 202222221897.3 discloses a fire hose connector, which includes an inner plug and an outer plug, both of which are tubular. The outer wall of the inner plug has an annular groove, and the inner wall of the outer plug is equipped with a wedge-shaped locking block. After the inner plug is inserted into the outer plug, the wedge-shaped locking block is engaged in the annular groove, preventing the inner plug from falling out of the outer plug. The outer wall of the left end of the inner plug is tapered with the smaller end facing left, and the inner wall of the outer plug has a tapered groove with the larger end facing left. The tapered groove is located to the left of the wedge-shaped locking block, and an annular sealing sleeve is installed in the tapered groove. The outer wall of the annular sealing sleeve is tapered and adapted to the inner wall of the tapered groove, and the inner wall of the annular sealing sleeve is tapered and adapted to the tapered surface of the left end of the inner plug. However, this type of fire hose connector requires a wedge-shaped locking block and a compression spring to lock the connector structure, which is relatively complex. The compression spring structure has poor stability. If the compression spring structure fails or gets stuck, a stable connection between the fire hose and the connector cannot be achieved, resulting in poor assembly stability of the fire hose connector, which is prone to falling off. Furthermore, its assembly method is relatively complex, which is not conducive to its widespread use. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1:

[0024] A press-fit fire hose harness fitting includes a hose body 1 and a fitting body 2. The hose body 1 is fitted onto one end of the fitting body 2. The fitting also includes an assembly mechanism for forming a press-fit positioning structure and a limiting mechanism for forming a uniformly distributed limiting structure. The assembly mechanism is located at the connection between the hose body 1 and the fitting body 2, and the limiting mechanism is located on the side of the fitting body 2 corresponding to the assembly mechanism. A cross-sectional view of the overall structure of Embodiment 1 of this utility model is shown below. Figure 1 As shown.

[0025] The two ends of the connector body 2 are a connecting end and an interface end, respectively. The connecting end is located at the end of the connector body 2 that is closer to the hose body 1. The end of the hose body 1 is fitted onto the outside of the connecting end of the connector body 2. The interface end is integrally formed with the connecting end, and the inner side of the end of the interface end that is away from the connecting end is provided with an interface groove structure. The connecting end is used as a connecting structure on the connector body 2 that mates with the hose body 1, and the interface end is used as an interface structure on the connector body 2 to meet the connection requirements between the connector and the fire hydrant or fire spray gun.

[0026] The assembly mechanism includes an assembly protrusion 3 and an assembly sleeve 4. The assembly protrusion 3 is located on the side of the connection end of the connector body 2 corresponding to the hose body 1 and is integrally formed with the connector body 2. The assembly sleeve 4 is located on the outer side of the end of the hose body 1 corresponding to the assembly protrusion 3 and is press-fitted to the hose body 1. The assembly mechanism forms a press-fit assembly structure by cooperating with the assembly protrusion 3 and the assembly sleeve 4 to assemble the hose body 1 onto the connector body 2. The assembly protrusion 3 is used as a limiting protrusion structure on the connector body 2 to cooperate with the assembly sleeve 4. The assembly sleeve 4 is pressed on the outer side of the connection between the hose body 1 and the connector body 2, thereby cooperating with the assembly protrusion 3 to securely assemble the hose body 1.

[0027] The assembly protrusion 3 is configured as an annular protrusion structure and located inside the hose body 1. The assembly sleeve 4 is located outside the assembly protrusion 3 and the hose body 1. The outer side of the middle part of the assembly sleeve 4 is configured as an annular protrusion structure corresponding to the assembly protrusion 3. The assembly sleeve 4 is formed by pressing aluminum alloy sheet material at the connection between the connector body 2 and the hose body 1. The side of the assembly sleeve 4 is provided with a seam. The assembly sleeve 4, made of aluminum alloy sheet material, can be pressed into shape in one go and is firm and reliable. It is easy to install and has low operating cost.

[0028] The limiting mechanism includes limiting base blocks 5 and limiting rubber rings 6. Several limiting base blocks 5 are evenly spaced on the side of the interface end of the connector body 2 and fixedly connected to it. The limiting base blocks 5 are arranged around the side of the interface end of the connector body 2. An installation groove is provided on the side of the limiting base blocks 5 away from the connector body 2. The limiting rubber rings 6 are fitted onto the sides of the limiting base blocks 5 and engage with them through the installation grooves. The limiting mechanism, through the cooperation of the limiting base blocks 5 and the limiting rubber rings 6, forms a limiting structure on the outer side of the interface end of the connector body 2, thereby improving the fitting accuracy between the anti-detachment mechanism and the connector body 2 and limiting the anti-detachment mechanism. Specifically, the limiting base blocks 5 provide installation support for the limiting rubber rings 6 and the top-holding assembly, and the limiting rubber rings 6 cooperate with the anti-detachment mechanism to improve the fitting accuracy between the anti-detachment mechanism and the connector body 2.

[0029] Example 2:

[0030] It also includes an anti-detachment mechanism, which includes an anti-detachment sleeve 7 and a supporting assembly. The anti-detachment sleeve 7 is located on the outside of the interface end of the connector body 2, and one end of it is threadedly connected to the interface end of the connector body 2. The supporting assembly is located on the side of the limiting base 5 near the assembly sleeve 4, corresponding to the anti-detachment sleeve 7. Several sets of supporting assemblies are provided for several limiting base blocks 5, and several sets of supporting assemblies are respectively arranged on the side of several limiting base blocks 5 near the assembly sleeve 4. The anti-detachment mechanism, through the cooperation of the anti-detachment sleeve 7 and the supporting assembly, provides a protective sleeve for the assembly mechanism to prevent the fire hose from falling off due to failure of the assembly mechanism. The anti-detachment sleeve 7 is used to protect the assembly sleeve 4 and prevent the assembly sleeve 4 from warping and loosening. The supporting assembly is used to elastically limit and support the anti-detachment sleeve 7 to prevent the connection between the anti-detachment sleeve 7 and the connector body 2 from loosening. The overall structural cross-sectional view of the second embodiment of this utility model is shown below. Figure 2 As shown.

[0031] The anti-detachment sleeve 7 has an installation end and an anti-detachment end at its two ends, respectively. The installation end of the anti-detachment sleeve 7 is threadedly connected to the interface end of the connector body 2. The anti-detachment end of the anti-detachment sleeve 7 is arranged on the outside of the assembly sleeve 4. The limiting base block 5 and the limiting rubber ring 6 are located on the inside of the anti-detachment sleeve 7. There is a gap between the limiting base block 5 and the anti-detachment sleeve 7. The limiting rubber ring 6 is arranged in close contact with the inner wall of the anti-detachment sleeve 7. In the working state, the anti-detachment end of the anti-detachment sleeve 7 is located on the outside of the end of the assembly sleeve 4 to prevent the assembly sleeve 4 from warping and loosening.

[0032] The supporting assembly includes supporting end blocks 8, supporting base blocks 9, and supporting springs 10. Two sets of supporting end blocks 8 are arranged side-by-side with a gap between them. One set of supporting end blocks 8 is located on the side of the limiting base block 5 near the assembly sleeve 4 and is fixedly connected to the limiting base block 5. Two sets of supporting base blocks 9 are also provided, each set located on the opposite side of the two sets of supporting end blocks 8 and fixedly connected to the corresponding supporting end blocks 8. A gap is left between the two sets of supporting base blocks 9, and the opposite sides of the two sets of supporting base blocks 9 have a receiving groove structure. The supporting spring 10 is located between the two sets of supporting base blocks 9, and its two ends are fixedly connected to the two sets of supporting base blocks 9 respectively. The end of the holding spring 10 is located inside the corresponding receiving groove. The holding assembly, through the cooperation of the holding end block 8, the holding base block 9, and the holding spring 10, serves as a holding limiting structure inside the anti-detachment sleeve 7 to prevent the anti-detachment sleeve 7 from falling off the connector body 2. The holding end block 8 provides installation support for the holding base block 9 and provides elastic limiting support for the anti-detachment sleeve 7 under the action of the holding base block 9 and the holding spring 10. The holding base block 9 provides elastic support for the holding end block 8 under the action of the holding spring 10. The holding spring 10 elastically connects the two sets of holding base blocks 9. A cross-sectional view of the holding assembly in Embodiment 2 of this utility model is shown below. Figure 3 As shown.

[0033] It also includes a support rod 11, which is disposed between two sets of support base blocks 9 and one end of which is fixedly connected to the corresponding support base block 9. The support rod 11 is located inside the support spring 10. The support rod 11 is used as a limiting support structure between the two sets of support base blocks 9, thereby providing limiting support for the support base blocks 9 and preventing the support spring 10 from jamming.

[0034] Since the diameter of the anti-detachment sleeve 7 and the diameter of the connecting end of the connector body 2 are both larger than the diameter of the assembly sleeve 4, the anti-detachment sleeve 7 generates friction with the outside during the dragging of the fire hose to effectively protect the assembly mechanism. The anti-detachment mechanism can be added or removed according to actual usage requirements.

[0035] Working principle:

[0036] In use, the ends of the hose body 1 are fitted onto the two ends of the connector body 2 as the connection ends. The assembly sleeve 4, made of aluminum alloy sheet material, is fitted onto the connection between the hose body 1 and the connector body 2. The assembly sleeve 4 is pressed into the connection between the two. Then, the anti-detachment sleeve 7 is rotated relative to the connector body 2 so that the anti-detachment end of the anti-detachment sleeve 7 is located outside the end of the assembly sleeve 4 to prevent the assembly sleeve 4 from warping and loosening. The assembly of the hose and the connector is thus completed. During operation, the supporting component can elastically support and limit the anti-detachment sleeve 7, thereby preventing the installation end of the anti-detachment sleeve 7 from falling off the interface end of the connector body 2.

[0037] The advantages of this utility model are its simple structure and assembly mechanism. The assembly sleeve and assembly protrusion cooperate to quickly assemble the fire hose onto the connector and ensure the assembly stability of the two. The assembly method is simple and direct, which is easy to promote and use. In addition, an anti-detachment mechanism and a limiting mechanism are provided to protect the assembly mechanism and prevent the fire hose from falling off the connector due to failure of the assembly mechanism, thereby further improving the assembly stability between the fire hose and the connector.

[0038] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
