Description

Technical Field

[0001] The utility model relates to the field of water gun buckles, in particular to an anti-dropping snap-on water gun buckle. Background Art

[0002] Fire hose is one of the more common fire-fighting tools. When connected to a fire hose or a fire truck, it can spray out dense and substantial water flow. Commonly used fire hoses include direct current hoses and spray hoses. Regardless of the type of hose, the hose and the water hose are locked together using a fire hose buckle.

[0003] The connection between the existing water gun buckle and the water hose buckle generally adopts a rotating combination method. When in use, they need to be aligned and connected first and then rotated to position the two. This connection method is not reliable enough. In actual use, when firefighters hold water guns for firefighting, a slight twist will cause the water gun buckle parts to reverse and disengage, which will cause emergencies and easily cause casualties to firefighters. Its safety and practicality need to be improved. Therefore, it is urgent to develop an anti-fall-off and easy-to-connect water gun buckle that can prevent the excessive impact of water flow or the firefighter's accidental twisting from causing the gun buckle body buckle parts to reverse and disengage, thereby improving safety and stability of use.

[0023] The buckle shaft section 11 of the gun buckle body 1 is also provided with a clamping structure 3 on the side close to the fire gun body 2, and the clamping structure 3 is sleeved and installed on the outer diameter surface of the gun buckle body 1 through a clamping ring 5; the clamping structure 3 includes a movable sleeve 31 sleeved on the outer diameter surface of the gun buckle body 1 on the side close to the fire gun body 2; the movable sleeve 31 is provided with a retaining ring 32 on the side close to the fire gun body 2, and the retaining ring 32 is fixedly connected to the movable sleeve 31 by bolts; the movable sleeve 31 is provided with an installation groove that penetrates the movable sleeve 31, and a clamping block 33 is slidably provided in the installation groove; the movable sleeve 31 A first spring 34 is also provided in the installation groove, and the first spring 34 is located between the block 33 and the retaining ring 32; a mounting shaft hole is provided on the inner ring surfaces of the movable ring 31 and the retaining ring 32, and a retaining ring 35 is slidably provided in the mounting shaft hole; a second spring 36 is also provided in the mounting shaft hole provided on the inner ring surfaces of the movable ring 31 and the retaining ring 32, and the second spring 36 is located between the retaining ring 35 and the mounting shaft hole; a snap-fit ​​groove 14 is also provided on the end face of the snap-fit ​​shaft section 11 of the gun buckle body 1 close to the snap-fit ​​structure 3, which penetrates the snap-fit ​​shaft section 11 and is connected with the snap-fit ​​groove 12.

[0024] Working principle:

[0025] The fire gun body 2 is fixedly connected to the gun buckle body 1 through a thread. When in use, the gun buckle body 1 is buckled with the buckle on the fire hose through the buckle pipe thread 13; the pipe thread of the buckle on the fire hose is snapped into the buckle groove 12; then the snap-in structure 3 sleeved on the outer diameter surface of the gun buckle body 1 is rotated, and when the installation groove set on the movable ring 31 is aligned with the snap-in groove 14 on the snap-in shaft section 11, the clamping block 33 slidingly set in the installation groove pops out under the action of the first spring 34, and the clamping block 33 extends from the installation groove and is snapped into the snap-in groove 14 set on the snap-in shaft section 11; the clamping block 33 passes through the snap-in groove 14 and extends to the snap-in groove 12 of the snap-in shaft section 11, limiting the pipe thread of the fire hose buckle, thereby circumferentially limiting the fire hose buckle, preventing the buckle component of the gun buckle body 1 from reversing and disengaging due to excessive water flow or accidental twisting by firefighters, thereby improving safety and stability in use.

[0026] After use, hold the clamping structure 3 and push the clamping structure 3 toward the side of the fire gun body 2, so that the movable ring 31 and the retaining ring 32 move toward the side of the fire gun body 2, and the second spring 36 is squeezed and shrinks toward the side of the retaining ring 35. When the movable ring 31 and the retaining ring 32 move a certain distance toward the side of the fire gun body 2, the clamping block 33 in the installation groove of the movable ring 31 is disengaged from the clamping groove 14 of the gun buckle body 1, and then the clamping structure 3 is rotated to one side by a certain angle to make the clamping block 33 staggered with the clamping groove 14 of the gun buckle body 1, and finally the clamping structure 3 is released. The second spring 36 pushes the movable ring 31 and the retaining ring 32 toward the side of the buckling shaft section 11 under the action of elastic force, and the clamping block 33 retracts into the installation groove of the movable ring 31 under the squeezing of the buckling shaft section 11 and the retaining ring 32.
