[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a fire hose quick connection device, comprising a device body 1 with a connecting pipe 2 embedded and fixedly connected at the top center, a splicing plate 3 fixedly connected to the lower edge of the outer periphery of the connecting pipe 2, slots for inserting matching splicing brackets 6 on both sides of the splicing plate 3, a splicing slot 4 provided between the inner top of the device body 1 and the outer periphery of the connecting pipe 2, and a locking hole 5 provided inside the splicing slot 4 through the front and back of the device body 1, and the upper edges of the front and back of the connecting pipe 2 fixedly connected to... There is a splicing bracket 6, and the inner side of the splicing bracket 6 has a groove that matches the size of the splicing plate 3 for mounting. The outer surface of the splicing bracket 6 is fixedly connected with a telescopic pin 7. The telescopic pin 7 is adapted to be mounted inside the lock hole 5. When the two device bodies 1 are quickly connected, after the splicing bracket 6 is inserted along the slots on both sides of the splicing plate 3, the device body 1 is rotated so that the groove of the splicing bracket 6 is mounted on the outer side of the splicing plate 3 until the telescopic pin 7 is mounted inside the lock hole 5, thus completing the quick connection of the fire hose.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The bottom of the main body 1 is provided with two sides of a sliding groove 8 for sliding adjustment of the first clamp 91 and the second clamp 92. A hose fixing assembly 9 for assembling and fixing the fire hose is provided between the inside of the sliding groove 8 and the two sides of the connecting pipe 2. The hose fixing assembly 9 includes a first clamp 91 and a second clamp 92 mirror-mounted on both sides of the connecting pipe 2. A sliding member 93 is fixedly connected to the top of both the first clamp 91 and the second clamp 92. The outer periphery of the sliding member 93 is slidably connected to the inside of the sliding groove 8. Anti-slip pads 94 for anti-slip clamping and fixing the fire hose are fixedly connected to the inner walls of both the first clamp 91 and the second clamp 92. A connecting screw 97 is fixedly connected to the center of the front and rear ends of the inner side of the first clamp 91. The connecting screw 97... A locking nut 98 is threaded through the right side of the second clamp 92. The inner sides of the first clamp 91 and the second clamp 92, and at both ends of the connecting screw 97, are provided with mounting grooves 95. A telescopic spring 96 is fixedly connected between the inside of the mounting grooves 95. When the locking nut 98 is not fitted onto the connecting screw 97 to lock the first clamp 91 and the second clamp 92, the telescopic spring 96 can support the first clamp 91 and the second clamp 92 to separate along the slide groove 8. This makes it easy to fit the fire hose around the bottom of the connecting pipe 2, and to quickly and easily connect and use the fire hose with anti-slip clamping by rotating the locking nut 98 to lock the first clamp 91 and the second clamp 92 with anti-slip pads 94.

[0033] Working principle: In use, when the locking nut 98 is not fitted with the connecting screw 97 to lock the first clamp 91 and the second clamp 92, the first clamp 91 and the second clamp 92 can be separated along the slide groove 8 by the telescopic spring 96. This allows the fire hose to be connected to be fitted onto the outer periphery of the bottom end of the connecting pipe 2. Then, the locking nut 98 is rotated to lock it, which drives the first clamp 91 and the second clamp 92 with anti-slip pads 94 to be compressed relative to each other along the slide groove 8, thus achieving anti-slip clamping connection of the fire hose. When two fire hoses with the device body 1 installed are quickly connected, after the splicing card 6 is inserted along the slots on both sides of the splicing card plate 3, the device body 1 is rotated so that the groove of the splicing card 6 is engaged with the outside of the splicing card plate 3 until the telescopic pin 7 on the outside of the splicing card 6 is engaged with the inside of the locking hole 5, thus completing the quick docking assembly of the fire hose with limit locking.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
