Description

Rotary quick connector

This invention relates to a fire hose connector, especially a rotary quick connector.

Fire is one of the more frequent modern disasters and often poses a major threat to people's lives and property. Especially in today's buildings, buildings or residential buildings are becoming the mainstream. In response to regulations and fire protection needs, fires are usually carried out every day. A fire box is set up on the floor and a fire hose is placed inside. Therefore, when a fire occurs in the building, it can extinguish the fire in time. However, the general fire hose has a fixed length. When the fire source is far away, When firefighting occurs, firefighters must use fire-fighting joints to connect two fire hoses to facilitate extinguishing fire sources that are far away.

However, when using fire-fighting joints to connect two fire hoses for disaster relief and fire extinguishing, strong water pressure or stair steps often cause the fire hose to twist or get stuck. When the twist occurs, it is easy to cause the fire hose to be twisted or stuck. The joints collide, and the locked structure may be released, causing the water to be unable to be continuously supplied, which affects the fire-extinguishing efficiency, or the fire joints are damaged due to impact. In addition, firefighters are often injured due to torsion, although there is a rubber ring buffer. Impact, but because the rubber ring is fixed, it has little buffering effect during impact.

Therefore, how to come up with a method that can avoid variables such as the collision of fire joints caused by the twisting or jamming of fire hoses, causing the fire joints to be disconnected under abnormal circumstances or causing personal injury, is a problem in the industry. required.

Accordingly, in order to solve the above-mentioned problems, the present invention proposes a rotary quick joint, which includes: a male joint arranged at one end of a first fire hose, and a female joint arranged at the end of a second fire hose. One end, wherein the female joint includes a joint ring set, the male joint and the female joint are combined with each other through the joint ring set, so that the first fire hose and the second fire hose can be firmly connected, the The joint ring group is assembled in sequence from a joint ring base, a rotating ring, a movable ring, a fixed ring and a rubber ring; wherein, the rubber ring is sleeved on the movable ring, and by The rotating ring performs circular rotation on the joint ring base.

In the rotary quick joint, the rotating ring is sleeved on the joint ring base and includes a plurality of cylinders arranged parallel to each other, and each of the cylinders rotates about an axis of the cylinder.

In the rotary quick joint, the movable ring is sleeved on the rotating ring, and through the rotation of the cylinders, the movable ring performs annular rotation on the base of the joint ring.

In the rotary quick joint, the joint ring base includes a locking part, and the fixing ring is locked to the locking part.

In the rotary quick joint, the joint ring base includes a platform portion, and the rotating ring is arranged on the platform portion.

In the rotary quick joint, one of the widths of the platform part is larger than the rotating ring, the movable ring and the rubber ring, so that the rotating ring, the movable ring and the rubber ring can rotate when they are stacked and combined. .

In the rotary quick joint, the fixing ring and the locking part are rotationally locked with threads.

In the rotary quick joint, the fixing ring and the locking part are locked in a snap-on manner.

In the rotary quick joint, there are a plurality of ball strings inside the rotating ring, which are arranged parallel to each other and rotate.

In the rotary quick joint, the surface of the rubber ring is composed of granular protrusions, striped protrusions or irregular protrusions.

Figure 1 shows a schematic diagram of the rotary quick connector of this invention.

Figure 2 shows an exploded view of the rotary quick joint of this invention.

Regarding the previously mentioned other technical contents, features and functions of this invention, the following detailed description with drawings and preferred embodiments will be clearly presented. The directional terms mentioned in the embodiments, such as: up, down, left, right, front or back, etc., are only for reference orientation. Therefore, the directional terms used are for illustrative purposes and are not used to limit the present invention. Creation.

First, please refer to Figure 1 and Figure 2, which is a rotary quick connector 100 of the present invention, which includes: a male connector 10, located at one end of a first fire hose 30, and a female connector 20, located at an end of a first fire hose 30. One end of the second fire hose 40, and the male connector 10 has a push ring 50. The push ring 50 is mainly used to release the connection between the male connector 10 and the female connector 20, that is, to connect the first fire hose 30 is separated from the second fire hose 40 . Wherein, the female joint 20 includes a joint ring set 60, the male joint 10 and the female joint 20 are combined with each other through the joint ring set 60, so that the first fire hose 30 and the second fire hose 40 can The joint ring group 60 is firmly connected, and the joint ring group 60 is composed of a joint ring base 61, a rotating ring 62, a movable ring 64, and a fixed ring in sequence. The fixed ring 65 and a rubber ring 66 are assembled. The rubber ring 66 is sleeved on the movable ring 64 and performs annular rotation on the joint ring base 61 by the rotating ring 62 .

As described in the rotary quick joint 100, when the joint ring group 60 is assembled, when the actual fire extinguishing water circulates and the fire hose is twisted or stuck, when the rubber ring 66 collides with a When the rubber ring 66 is flat, the rubber ring 66 is connected with the movable ring 64 and rotates through the rotating ring 62. Accordingly, the torsion phenomenon can be effectively eliminated to avoid the collision of the fire joint when the torsion occurs, and the locked structure is released. , causing the water to be unable to be continuously supplied, affecting the fire extinguishing efficiency, or causing damage to the fire joint due to impact. In addition, firefighters are often injured due to torsion.
