Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a universal foaming cylinder for fire monitors. Background Technology

[0002] Foaming cylinders are specialized foaming attachments installed on fire monitor heads, playing a crucial role in extinguishing oil fires. Currently, fire monitors come in numerous specifications and models, especially with varying head styles. To achieve foam extinguishing, corresponding foaming cylinders are required. However, different specifications and models of foaming cylinders are not interchangeable, leading to confusion at fire scenes and impacting firefighting efficiency. Some patents, such as fire foam monitor tubes and foam cannons (CN210145370U), provide a fire foam monitor tube with quick-clamping functionality; however, its structure is only applicable to a single model and size of fire monitor, lacking versatility and failing to solve the current problem of universal clamping for multiple uses with a single cylinder. Utility Model Content

The outer clamping plate 201 and the inner clamping plate 203 are installed in a nested configuration, with the inner clamping plate 203 entirely located inside the outer clamping plate 201. The outer clamping plate 201 and the inner clamping plate 203 can rotate freely relative to each other; an outwardly protruding outer plate gripping handle 202 is fixed to the outside of the outer clamping plate 201, and an outwardly protruding inner plate gripping handle 204 is fixed to the outside of the inner clamping plate 203. The inner plate gripping handle 204 extends out after passing through the outer clamping plate 201, and an inner plate gripping handle hole 2041 is provided on the inner clamping plate 203 for the inner plate gripping handle 204 to pass through and be adjusted; multiple synchronous clamping arms 206 are hinged to the surfaces of the outer clamping plate 201 and the inner clamping plate 203, and the synchronous clamping arms 206 expand or retract through the relative displacement of the outer clamping plate 201 and the inner clamping plate 203; a flexible clamping end 207 is fixed to the end of each of the multiple synchronous clamping arms 206.

[0006] This utility model also has the following additional technical features:

Detailed Implementation

[0016] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0017] A universal foaming cylinder for fire monitors includes an integrated foaming cylinder 1 and a nozzle diameter-changing centering clamp 2. The integrated foaming cylinder 1 is used for the intake, foaming, and straightening of foam mixtures for spraying. The nozzle diameter-changing centering clamp 2 is used for clamping nozzles of various specifications and diameters, and ensures that the foaming cylinder 1 and the nozzle are concentrically fixed, remaining stable and not detached during fire monitor spraying.

[0018] The integrated foaming cylinder 1 includes an air-absorbing tapered cylinder 101 and an annular stud matrix 102; the air-absorbing tapered cylinder 101 has a tapered profile, and the end of the air-absorbing tapered cylinder 101 is fixed with several inwardly extending studs by bolts, and the several studs together form an annular stud matrix 102.

[0019] The gun head diameter changing centering fixture 2 includes an outer clamping plate 201, an outer clamping handle 202, an inner clamping plate 203, an inner clamping handle 204, a locking mechanism 205, a synchronous clamping arm 206, and a flexible clamping end 207.

[0020] The outer clamping plate 201 and the inner clamping plate 203 are installed as a nested unit, with the inner clamping plate 203 entirely located inside the outer clamping plate 201. The outer clamping plate 201 and the inner clamping plate 203 can rotate freely relative to each other. In actual use, the inner side of the outer clamping plate 201 has an outwardly protruding slider, and the outer side of the inner clamping plate 203 has an inwardly recessed groove. The slider of the outer clamping plate 201 engages with the groove of the inner clamping plate 203, allowing both to rotate freely relative to each other without falling off.

[0021] An outwardly protruding outer disc grip handle 202 is fixed to the outside of the outer disc 201, and an outwardly protruding inner disc grip handle 204 is fixed to the outside of the inner disc 203. By swinging the outer disc grip handle 202 and the inner disc grip handle 204 closer or further away, the outer disc 201 and the inner disc 203 can rotate relative to each other.

[0022] Meanwhile, to facilitate rotation, the inner disc grip handle 204 extends out after passing through the outer clamping plate 201, and the inner clamping plate 203 is provided with an inner disc grip handle hole 2041 for the inner disc grip handle 204 to pass through and be adjusted. The size of the inner disc grip handle hole 2041 can determine the relative rotation angle between the outer clamping plate 201 and the inner clamping plate 203.

[0023] Multiple synchronous clamping arms 206 are hinged to the surfaces of the outer clamping plate 201 and the inner clamping plate 203. The synchronous clamping arms 206 are hinged to the surface of the inner clamping plate 203 via pins, and are connected to the surface of the outer clamping plate 201 via a slider and groove-type hinge. The synchronous clamping arms 206 expand or retract due to the relative displacement of the outer clamping plate 201 and the inner clamping plate 203. Each of the multiple synchronous clamping arms 206 has a flexible clamping end 207 fixed to its end.

[0024] A locking mechanism 205 is installed on one side of the outer clamping plate 201, and the locking mechanism 205 is connected to the inner plate gripping handle 204. The locking mechanism 205 can lock and limit the position of the inner plate gripping handle 204 and the outer clamping plate 201 after the synchronous clamping arm 206 has a suitable outer diameter, thereby ensuring that the synchronous clamping arm 206 is always located at the same outer diameter position and will not expand or retract.

[0025] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
