Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, and relates to a fire fighting joint, in particular to a new type of fire fighting joint. Background Technique

[0002] The purpose of fire fighting is to reduce the degree of damage caused by fires and reduce casualties and property losses. In actual fire fighting operations, various fire fighting facilities are required, and a fire fighting interface is a fire fighting facility structure for connecting fire hoses, fire fighting water pipes to fire fighting water guns, fire trucks, fire pumps, etc.

[0003] Most of the existing fire fighting interfaces for quick docking adopt a threaded structure. When docking, the interface is screwed onto the docking seat. However, due to the threaded connection, the rotation process is rather troublesome and requires a large amount of effort to screw the interface onto the docking seat. Therefore, it will consume more time, thus reducing the docking efficiency of the fire fighting interface. Moreover, if the interface is not tightly screwed onto the docking seat, water is very likely to flow out from the gap between the interface and the interface seat, thereby affecting the sealing performance after the installation of the fire fighting interface and the water delivery efficiency. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of fire fighting joint with quick installation for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of fire fighting joint includes an unlocking ring, a male interface, and a female interface. It is characterized in that a clamping portion is provided on the male interface, a clamping groove is provided on the male interface, a clamping device is provided in the female interface opposite to the clamping groove, an installation groove for installing the clamping device is provided in the female interface, the clamping device is composed of a clamping protrusion and a return spring, a sealing portion is provided at the front end of the male interface, a sealing groove for installing the sealing portion is provided on the female interface opposite to the sealing portion, and a sealing ring is provided on the inner wall of the sealing groove.

[0006] In the above-mentioned new type of fire fighting joint, the clamping protrusion is provided with an inclined portion.

[0007] In the above-mentioned new type of fire fighting joint, a longitudinal chute is provided on the male interface, a transverse chute communicating with the longitudinal chute is provided on the male interface, a slider is provided on the inner wall of the unlocking ring, and the slider can move in the transverse chute and the longitudinal chute.

[0008] In the above-mentioned new type of fire fighting joint, annular grooves are provided on both the male interface and the female interface.

[0009] Compared with the prior art, the clamping device provided by the utility model can realize the quick connection of the male interface and the female interface. The sealing part, the sealing groove and the sealing ring make the connection more sealed. The transverse sliding groove, the longitudinal sliding groove and the slider of the unlocking ring enable the unlocking ring to be fixed on the male interface, avoiding the loss of the unlocking ring and also preventing the failure of the connection between the male interface and the female interface caused by accidental contact with the unlocking ring during use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0016] As Figure 1 , Figure 2 , Figure 3 . Figure 4 As shown, the new type of fire fighting joint includes an unlocking ring 1, a male interface 2 and a female interface 3. A clamping part 4 is provided on the male interface 2, and a clamping groove 5 is provided on the male interface 2. A clamping device 6 is provided in the female interface 3 and opposite to the clamping groove 5. An installation groove 7 for installing the clamping device 6 is opened in the female interface 3. The clamping device 6 is composed of a clamping convex block 8 and a return spring 9. A sealing part 10 is provided at the front end of the male interface 2. A sealing groove 11 for installing the sealing part 10 is opened on the female interface 3 and opposite to the sealing part 10. A sealing ring 12 is provided on the inner wall of the sealing groove 11.

[0017] Further elaborating, the clamping convex block 8 is provided with an inclined part 13.

[0018] To elaborate further, a longitudinal chute 14 is provided on the male interface 2, and a transverse chute 15 communicating with the longitudinal chute 14 is provided on the male interface 2. A slider 16 is provided on the inner wall of the unlocking ring 1, and the slider 16 can move within the transverse chute 15 and the longitudinal chute 14. The transverse chute 15, the longitudinal chute 14, and the slider 16 of the unlocking ring 1 enable the unlocking ring 1 to be fixed on the male interface 2, preventing the loss of the unlocking ring 1 and also preventing the failure of the connection between the male interface 2 and the female interface 3 due to accidental touch of the unlocking ring 1 during use.

[0019] To elaborate further, annular grooves 17 are provided on both the male interface 2 and the female interface 3.

[0020] Principle of use: During installation, the female interface 3 is pressed into the male interface 2. The clamping portion 4 of the male interface 2 comes into contact with the inclined portion 13 of the clamping projection 8, and the clamping projection 8 is pressed into the installation groove 7 until the sealing portion 10 completely enters the sealing groove 11. Just when the clamping projection 8 reaches the position of the clamping groove 5, the clamping projection 8 automatically resets without restraint and clamps the clamping portion 4. During unlocking, the unlocking ring 1 is slid into the longitudinal chute 14 and pushed towards the inside of the female interface 3 to squeeze the clamping block, and at the same time, the male interface 2 is pulled out together to complete unlocking.
