Abstract
Description
Technical Field
[0001] This invention relates to a circuit fuse mechanism for a certain type of fire sprinkler, belonging to the field of fire extinguisher circuit technology, and particularly to a circuit fuse mechanism. Background Technology
[0002] Currently, a certain type of fire sprinkler lacks a circuit safety mechanism, resulting in unstable and uneven spraying, and is particularly prone to misoperation, leading to low overall product reliability and affecting emergency fire fighting. To address these issues, a circuit safety mechanism has been designed. Summary of the Invention
[0003] The purpose of this invention is to overcome the defects of existing fire sprinkler products and design a circuit safety mechanism, which includes a housing (1), a fixing block (2), a micro switch (3), a micro switch upper contact (3a), an electrical safety assembly (4), an electrical safety assembly spring plate (3a), a spring (3b), a retaining ring (3c), an electrical safety shaft (3d), a trigger (5), a trigger shaft (6), and a torsion spring (7). The improved fire sprinkler uses a circuit safety mechanism, and the fire sprinkler can only complete normal spraying when the circuit safety mechanism is opened. The spraying is stable and uniform, and it can prevent accidental spraying, thus improving the safety and reliability of the sprinkler. Attached Figure Description
[0004] Figure 1 This is a structural diagram of a circuit fuse mechanism;
[0005] Figure 2 Schematic diagram of electrical fuse components.
[0006] like Figure 1 As shown: housing (1), fixing block (2), micro switch (3), upper contact of micro switch (3a), electrical fuse assembly (4), spring plate of electrical fuse assembly (3a), spring (3b), retaining ring (3c), electrical fuse shaft (3d), trigger (5), trigger shaft (6), torsion spring (7).
[0007] like Figure 2 As shown: the spring sheet (4a) of the electrical fuse assembly. Detailed Implementation
[0008] The specific implementation method and working principle are as follows: Press the electric fuse assembly (4) by hand. The spring plate (3a) of the electric fuse assembly moves towards the contact (3a) of the micro switch. After it reaches the position, pull the trigger (4) to rotate the trigger (4) counterclockwise upward. The trigger (4) squeezes the spring plate (4a) of the electric fuse assembly, which in turn presses the contact (3a) of the micro switch, thus connecting the circuit. After spraying is completed, release the electric fuse assembly (4). The electric fuse assembly (4) resets under the action of the spring (3b). That is, spraying can only be completed after opening the circuit fuse mechanism and operating in sequence.
Claims
1. A circuit fuse mechanism, characterized in that: The components include a housing (1), a fixing block (2), a micro switch (3), an upper contact of the micro switch (3a), an electrical safety assembly (4), an electrical safety assembly spring plate (3a), a spring (3b), a retaining ring (3c), an electrical safety shaft (3d), a trigger (5), a trigger shaft (6), and a torsion spring (7). After the improvement, a certain type of fire sprinkler can only complete normal spraying when the circuit safety mechanism is opened. The spraying is stable and uniform during spraying, and can prevent accidental spraying.
