Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a nozzle structure with a direction adjustment structure for a fire extinguishing device. Background Art

[0002] Fire extinguishing device is another term for fire extinguishing products. Dry powder fire extinguisher is a kind of fire extinguishing product. The fire extinguisher is filled with dry powder fire extinguishing agent such as ammonium phosphate. This dry powder fire extinguishing agent has easy flowability and dryness. It is composed of inorganic salts and crushed and dried additives. It can effectively extinguish initial fires. Conventional divergent spray nozzles can meet the fire extinguishing requirements, but a large amount of dry powder cannot be sprayed onto the fire point, which is easy to cause waste. In order to improve the efficiency of the use of fire extinguishing devices, a nozzle structure is needed, but the existing nozzle structure still has the following shortcomings:

[0003] For example, the utility model with application number 202020951921.7 discloses a fire extinguishing device. The fire extinguishing device provided by the utility model can push the fire extinguishing agent to extinguish the fire under the action of the gas-producing structure, thereby avoiding turbulence caused by the fire extinguishing agent being sprayed out of the nozzle and the surplus space in the storage chamber, thereby ensuring that the fire extinguishing agent can be fully sprayed. However, similar to the comparative documents of the above-mentioned application, when the existing nozzle structure is used, since the spraying direction of most nozzle structures is relatively single and fixed, the fire extinguishing efficiency is easily affected and the waste of materials is increased, resulting in the problem of reduced practicality of the nozzle structure and reduced utilization efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a nozzle structure for a fire extinguishing device with a directional adjustment structure is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a nozzle structure for a fire extinguishing device with a direction adjustment structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nozzle structure for a fire extinguishing device with a directional adjustment structure, comprising a nozzle body and a movable nozzle, a discharge channel is opened on the right side inside the nozzle body, a limiting cavity is opened on the left side inside the nozzle body, and a limiting ring is added to the outside of the limiting cavity, and the movable nozzle is connected to the inside of the limiting cavity, a discharge port is added to the middle end of the outside of the movable nozzle, and an installation component is arranged outside the discharge port.

[0007] Furthermore, the discharge channel is embeddedly connected to the nozzle body, and the front end of the discharge channel is connected to the limiting cavity.

[0008] Furthermore, the inner dimensions of the limiting cavity match the outer dimensions of the movable nozzle, and the movable nozzle is connected to the nozzle body through the limiting cavity.

[0009] Furthermore, the outer side of the limiting ring is tightly fitted with the outer side of the limiting cavity, and the limiting ring is fixedly connected to the limiting cavity.

[0010] Furthermore, the discharge port and the movable nozzle are vertically distributed, and the discharge port is threadedly connected to the movable nozzle.

[0011] Furthermore, the installation assembly includes a docking groove, a sealing docking ring, a threaded installation groove, a threaded installation block and a discharge nozzle, the docking groove is internally connected to a sealing docking ring, the front end inner surface of the discharge port is provided with a threaded installation groove, the discharge port is internally connected to a threaded installation block, and the discharge nozzle is arranged outside the threaded installation block.

[0012] Furthermore, the inner dimensions of the docking groove match the outer dimensions of the sealing docking ring, and the sealing docking ring is connected to the discharge port through the docking groove.

[0013] Furthermore, the inner dimensions of the threaded mounting groove match the outer dimensions of the threaded mounting block, and the threaded mounting block is rotatably connected to the discharge port via the threaded mounting groove.

[0014] The utility model provides a nozzle structure for a fire extinguishing device with a direction adjustment structure, which has the following beneficial effects:

[0015] 1. The utility model, through the arrangement of the movable nozzle, can avoid the problem that the spraying direction of most nozzle structures is relatively single and fixed when the nozzle structure of the fire extinguishing device with the adjustment structure is used, which makes the fire extinguishing efficiency easily affected and increases the waste of materials, resulting in the problem of reduced practicality of the nozzle structure. The fire extinguishing material in the fire extinguishing device is transported through the discharge channel opened in the nozzle body, and the material is transported to the inside of the limiting cavity in cooperation with the discharge channel. At the same time, the internal size of the limiting cavity matches the external size of the movable nozzle, so that the movable nozzle is installed in the nozzle body through the limiting cavity, and the limiting cavity and the movable nozzle are both spherical, so that the movable nozzle can rotate freely in the limiting cavity, and the limiting ring installed outside the limiting cavity limits the movable nozzle while avoiding the overflow of materials, thereby improving the use efficiency of the nozzle structure and increasing the flexibility of the fire extinguishing device during use.

[0016] 2. The utility model can avoid the situation that most nozzle structures are difficult to quickly complete the installation of nozzles of corresponding calibers according to actual needs when using the nozzle structure of the fire extinguishing device with a directional adjustment structure through the arrangement of the installation components, which makes it difficult to flexibly adjust the spraying intensity of the material, resulting in reduced efficiency of the nozzle structure. The internal dimensions of the threaded installation groove provided on the inner surface of the front end of the discharge port match the external dimensions of the threaded installation block added at the rear end of the discharge nozzle, so that the discharge nozzle can be rotatably installed inside the inlet and outlet through the threaded installation groove and the threaded installation block, and the spraying intensity of the material inside the fire extinguishing device can be adjusted by replacing the discharge nozzle. At the same time, the internal dimensions of the docking groove provided at the front end of the discharge port match the external dimensions of the sealing docking ring, so that the sealing docking ring is limited inside the front end of the discharge port through the docking groove, so that when the discharge nozzle rotates inside the inlet and outlet, the sealing docking ring increases the overall sealing after the rotation installation, thereby avoiding the overflow of the material inside the fire extinguishing device and improving the overall efficiency of the fire extinguishing device.
