[0030] In order to realize the switching and fixing of third connecting end 201 between the first state and the second state, in the embodiment, the inner side of second interface part 2 is provided with first internal thread 221, the outer side of first interface part 1 is provided with first external thread 121, the first internal thread 221 is screwed with the first external thread 121, so that the second interface part 2 can rotate along the first interface part 1, when rotating, the second interface part 2 can move along the axial direction of the first interface part 1, after moving to the predetermined position, the second interface part 2 stops rotating, at this time, the second interface part 2 can be locked through the thread connection of the first internal thread 221 and the first external thread 121, avoiding loosening or falling off in the process of use.In addition, the thread connection should have good waterproof performance, effectively reducing the leakage phenomenon between the second interface and the first interface.

[0031] In one of the embodiments, the first interface part comprises a center sleeve 11 and a connecting sleeve 12, and the second interface part comprises a movable sleeve 22. Specifically, the two ends of the center sleeve 11 form a first connecting end 101 and a second connecting end 102 respectively, and the connecting ends of the first interface part 1 are designed for threaded connection with the fire-fighting interface. The outer side of the connecting end can be equipped with a second external thread, or the inner side thereof can be equipped with a second internal thread, to adapt to different models of fire-fighting interfaces. By selecting an adapter equipped with an external thread or an internal thread, an adaptive connection with the fire-fighting interface can be achieved. The connecting sleeve 12 is sleeved on the outside of the center sleeve 11, and the first connecting end 101 and the second connecting end 102 are respectively located outside the two ends of the connecting sleeve 12. One end of the movable sleeve 22 forms a third connecting end 201, and the movable sleeve 22 is sleeved on the outside of the connecting sleeve 12 and is threadedly connected with the connecting sleeve 12 through a first external thread 121 and a first internal thread 221. Among them, the second connecting end 102 and the third connecting end 201 adopt an external thread or a protruding buckle structure, and can be connected with a (65 / 80) female or bayonet type interface.

[0032] When a 65 type interface needs to be connected at the other end of the converter, the movable sleeve 22 can be rotated to move along the axial direction of the connecting sleeve 12 to a first state, at this time, the second connecting end 102 is completely outside the third connecting end 201, and the second connecting end 102 can adapt to the 65 type interface. When a 80 type interface needs to be connected, the operator reversely rotates the movable sleeve 22, and the movable sleeve 22 moves along the axial direction of the connecting sleeve 12 to a second state, at this time, the second connecting end 102 is retracted in the third connecting end 201, and the third connecting end 201 can adapt to the 80 type interface.

[0034] Of course, in other possible embodiments, the second interface part 2 and the first interface part 1 can also be connected and locked in other ways, for example, the inner side of the second interface part 2 is connected to the outer side of the first interface part 1 by sliding, the inner side of the second interface part 2 is provided with a buckle structure, and the outer side of the first interface part 1 is provided with a card slot matched with the buckle structure, when the second interface part 2 moves to a predetermined position along the axial direction of the first interface part 1, the buckle structure can be clamped into the card slot, thereby realizing the connection and locking of the second interface part 2 and the first interface part 1. In addition, the first connecting end 101, the second connecting end 102 and the third connecting end 201 are not limited to the above structure, and can also be designed into other shapes and sizes according to actual needs to adapt to different types of interfaces.

[0035] In some possible embodiments, the outer side of the second interface part 2 is provided with a locking member connected to the second interface part 2 for fixing the relative position of the second interface part 2 and the first interface part 1.

[0036] Preferably, in the present embodiment, the locking member includes a limiting sleeve 3 and a limiting push plate 31, the limiting sleeve 3 is movably sleeved on the outer side of the second interface part 2, and the inner side of the limiting sleeve 3 is provided with a partially inwardly recessed limiting groove, one end of the limiting push plate 31 is connected to the limiting sleeve 3, and the other end extends along the radial direction of the second interface part 2. When it is necessary to lock the second interface part 2, the operator can push the limiting push plate 31 to drive the limiting sleeve 3 to move along the axial direction of the movable sleeve 22 until the limiting groove is clamped into the outer side of the movable sleeve 22, and then the limiting sleeve 3 is fixed on the interface when the second connecting end 102 is connected to the interface, which can limit the rotation of the movable sleeve 22, thereby realizing the locking of the second interface part 2 and the first interface part 1, and ensuring that the two cannot rotate or axially displace relative to each other after being correctly aligned. Under the action of fire water pressure, the threaded engagement surface between the sleeves and the limiting sleeve jointly bear the axial force, further stabilizing the connection.

[0037] Of course, in other possible embodiments, the locking member can also have other structure forms, for example, the locking member can include an elastic buckle and a locking ring, the elastic buckle is arranged on the outer side of the second interface part 2, and the locking ring is sleeved on the second interface part 2 and can move along the axial direction thereof, when the locking ring moves to a predetermined position, the elastic buckle can be clamped into the card slot in the locking ring, thereby realizing the locking of the second interface part 2 and the first interface part 1.

[0040] Further, the interface converter is 16 cm long, has a maximum outer diameter of 8.5 cm, and weighs 700 g. It has a small volume, a light weight, and is convenient to carry and easy to operate. Through practical operation training tests, it can complete the quick conversion of 65 and 80 interfaces within 5 seconds, simultaneously reduces the carrying of interfaces, and realizes the case of carrying one converter instead of multiple interfaces.

[0041] In order to better understand the utility model, the following will be combined with Fig. 1 and Fig. 2 The technical scheme of the utility model is described in detail: in use, the operator first connects the first connecting end 101 of the center sleeve 11 with the fixed interface end of the fire-fighting equipment. If a 65-type interface needs to be connected, the operator rotates the movable sleeve 22 clockwise, the movable sleeve 22 moves along the axial direction of the connecting sleeve 12, until the second connecting end 102 completely extends outside the third connecting end 201, at this time, the second connecting end 102 is adapted to the 65-type interface, and the 65-type interface can be connected with the second connecting end 102. If it needs to be converted to connect an 80-type interface, the operator rotates the movable sleeve 22 counterclockwise, the movable sleeve 22 moves along the axial direction of the connecting sleeve 12, until the second connecting end 102 is retracted in the third connecting end 201, and then the 80-type interface is connected with the third connecting end 201.

[0042] The utility model adjusts the third connecting end 201 to the first state or the second state, and realizes the quick switching between various interfaces through the extension and retraction of the second connecting end 102, effectively reduces the replacement time, and improves the water supply efficiency. The interface converter adopts an integrated design, reduces the carrying burden, avoids the inconvenience of carrying multiple independent conversion connectors in actual work, optimizes the equipment configuration, and facilitates the firefighters to quickly respond to various fire extinguishing needs.
