Description

General foaming section of thick bamboo of fire gun Technical Field The utility model relates to the technical field of fire control, in particular to a general foaming barrel for a fire monitor. Background The foaming cylinder is a special foaming accessory arranged on the head of the fire monitor and plays an important role in extinguishing oil fires. The current fire monitor has various specifications and models, particularly gun heads with different styles, so that foaming cylinders with corresponding models are required to be provided for realizing foaming and fire extinguishing, and the foaming cylinders with different specifications and different models are not universal, so that the fire monitor is easy to mix up in a fire scene, has different forms, and influences the fire extinguishing efficiency to a certain extent. Some patents such as fire-fighting foam gun tubes and foam guns (CN 210145370U) provide a fire-fighting foam gun tube with a quick clamping function, but the structure of the fire-fighting foam gun tube is only applicable to fire-fighting guns with single model sizes, has no universality and cannot solve the problem of the current multipurpose universal clamping of a barrel. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides the universal foaming barrel which can realize quick clamping and is suitable for fire monitor of various specifications. The technical scheme adopted for solving the technical problems is as follows: A universal foaming barrel for a fire monitor comprises an integrated foaming barrel 1 and a gun head variable-diameter centering clamp 2, wherein the integrated foaming barrel 1 is used for sucking foaming and rectifying spraying of foam mixed liquid, the gun head variable-diameter centering clamp 2 is used for clamping of gun heads with different diameters in multiple specifications, the foaming barrel 1 and the gun heads are ensured to be concentrically fixed, the universal foaming barrel is kept stable and not separated in a fire monitor spraying state, the gun head variable-diameter centering clamp 2 comprises an outer clamping disc 201, an outer clamping disc clamping handle 202, an inner clamping disc 203, an inner clamping disc clamping handle 204, a locking mechanism 205, a synchronous clamping arm 206 and a flexible clamping end 207, the outer clamping disc 201 and the inner clamping disc 203 are mounted in a sleeved mode, the inner clamping disc 203 is integrally located in the outer clamping disc 201, the outer clamping disc 201 and the inner clamping disc 203 can rotate freely relatively, an outer clamping disc clamping handle 202 which is externally fixed to the outer clamping disc 201, an inner clamping disc clamping handle 204 which is externally fixed to the outer clamping disc 203 extends out after penetrating through the outer clamping disc 201, the inner clamping disc 204 is provided with an inner clamping disc 204, the inner clamping disc 206 is used for being connected with the inner clamping disc 206 through holes of the outer clamping disc 203, and the outer clamping disc 203 is connected with the synchronous clamping arms 203 in a sleeved mode, and the synchronous clamping ends of the synchronous clamping arms 203 are connected with the synchronous clamping arms 201, or the synchronous clamping ends are connected with the synchronous clamping arms 203 through the synchronous clamping ends which are connected with the synchronous clamping arms 201.
