Technical Field

[0001] This utility model relates to the field of small hole cleaning technology, specifically to a tool for cleaning small holes in a fire sprinkler hydraulic alarm bell. Background Technology

[0002] A fire alarm bell is an audible and visual alarm device for fire alarm and emergency evacuation. It belongs to the category of alarm controllers and activates continuous alarm signals through an output module. It is mainly used in dormitories, production workshops, corridors and other places, and also has the function of burglar alarm. It is usually linked with a fire alarm controller for triggering.

[0003] The fire alarm bell has a small hole at the front connection. Due to the size of the hole and the quality of the fire water, the hole is prone to blockage, which greatly affects the normal operation of the fire alarm bell. Cleaning the hole requires removing the entire fire alarm bell, which is time-consuming and extremely inconvenient. Summary of the Invention

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In one specific embodiment of this utility model, such as Figures 1-3 As shown, a cleaning fixture for the small hole of a fire sprinkler hydraulic alarm bell includes a housing 1 and a crank push rod mechanism 2, a guide rod 3 and a brush 4 disposed inside the housing. The guide rod 3 is connected to the housing 1 through a support rod 5. The brush 4 is slidably mounted on the guide rod 3. A drive motor 6 is disposed on the upper part of the housing 1. The output end of the drive motor 6 is connected to the input end of the crank push rod mechanism 2. The output end of the crank push rod mechanism 2 is connected to one end of the brush 4.

[0018] The crank-puss mechanism 2 includes a rotating shaft 21, a rocker arm 22, and a connecting rod 23. The rotating shaft 21 is rotatably inserted into one side wall of the housing 1. A fixed plate 24 is installed at one end of the rotating shaft 21 inside the housing 1. The rocker arm 22 is fixedly connected to the fixed plate 24. The end of the rocker arm 22 away from the fixed plate 24 is rotatably connected to the connecting rod 23. A slider 25 is rotatably connected to the end of the connecting rod 23 away from the rocker arm 22. The slider 25 is slidably mounted on the guide rod 3 and is connected to the brush 4. A pulley 26 is provided at one end of the rotating shaft 21 extending out of the housing 1. A pulley 7 is connected to the output end of the drive motor 6. A belt 8 is connected between the pulley 26 and the pulley 7.

[0019] Two mounting seats 9 are provided on the guide rod 3, and the brush 4 slides through the mounting seats 9.

[0020] Both ends of the housing 1 are provided with threaded joints 10, the bottom of the housing 1 is provided with a drain port 11, and a sight glass 12 is provided on one side wall of the housing 1.

[0021] like Figures 4-8 As shown, the rotating shaft 21 has a cross-shaped sliding groove 13 and a temporary storage groove 14. A sliding rod 15 is slidably disposed in the sliding groove 13, and a handle 16 is slidably inserted in the temporary storage groove 14. The sliding rod 15 and the handle 16 are rotatably connected.

[0022] The end of the handle 16 that extends into the temporary storage slot 14 is provided with a waist-shaped hole 17, and the sliding rod 15 passes through the waist-shaped hole 17.

[0023] The end of the side wall of the temporary storage groove 14 is provided with a slot 18, and the end of the slide groove 13 is provided with a limiting part 19.

[0024] A limit rod 20 is provided at the end of the handle 16, and the limit rod 20 is locked in the slot 18.

[0025] The process of using this utility model: The housing is equipped with threaded connectors at both ends. The device is connected to the pipeline at the front end of the fire alarm bell hole through the threaded connector 10. Driven by a drive motor 6, the drive motor 6 drives the rotating shaft 21 to rotate via a belt 8. The rotating shaft 21 drives the swing arm 22 to rotate. The swing arm 22 drives the slider 25 to slide back and forth on the guide rod 3 via a connecting rod 23. The brush 4 moves back and forth with the slider 25, thereby cleaning the small hole. When not in use, the handle 16 is stored in the temporary slot 14 of the rotating shaft 21. When the handle 16 needs to be used for driving, pull the limit rod 20 to pull the handle 16 out of the rotating shaft 21 until the sliding rod 15 is blocked by the limit part 19. Rotate the handle 16 90° to be perpendicular to the rotating shaft 21. Since the handle 16 is provided with a waist-shaped hole 17, the sliding rod 15 passes through the waist-shaped hole 17, so that the handle 16 can have a certain distance of movement after being pulled out. The handle 16 can be better inserted into the slot 18, increasing the contact area between the handle 16 and the slot 18 and increasing the point of force. By rotating the handle 16, the function of the drive motor 6 can be replaced, thereby using the brush 4 to effectively clean the small holes. In normal circumstances without a fire alarm, the pipe at the front end of the fire alarm bell is not filled with water, and the drain port 11 is sealed with a plug. After water is introduced, due to the structure of the housing 1, water is likely to accumulate inside the housing 1 after the water drains from the pipe. In order to avoid damage to the internal devices of the housing 1 caused by the accumulated water, the drain port 11 can be used to drain the accumulated water inside the housing 1.

[0026] Unless otherwise specified or further limited to one preferred or alternative technical means being another, the preferred and alternative technical means disclosed in this utility model can be arbitrarily combined to form several different technical solutions. Therefore, equivalent changes made according to the claims are still within the scope of this utility model.
