Technical Field
[0001] The utility model relates to the technical field of telescopic rods, and specifically relates to a combined multifunctional telescopic rod for maintenance of subway stations. Background Art
[0002] The telescopic rod is a rod-shaped structure with adjustable length, which is widely used in various occasions that require length adjustment. The utility model is mainly used in subway stations. Each equipment room in the subway station has a wall groove, which is narrow and relatively long, and it is extremely difficult to clean foreign objects and silt in it. There are high-altitude equipment such as cameras and speakers at each outdoor entrance and exit of the subway station. The height of the camera is relatively high. If there is strong wind, the camera will be hung with foreign objects, which will seriously affect the camera monitoring; the installation height of the speaker is about 8-10 meters. Due to weather or insects, it is easy to cause corrosion, dirt, foreign objects, etc. on the surface of the speaker. Cleaning requires climbing and setting up, and the labor cost is high; when other high-altitude equipment fails, it is difficult to find the cause of the failure due to height restrictions. It is necessary to climb or climb up to set up for investigation, which increases the timeliness and difficulty of handling.

The rubber sleeve is hollow, and a plurality of teeth and grooves are evenly distributed on the inner wall of the rubber sleeve. A connector is interference fit on the end of the inner tube, and the outer wall of the connector is in contact with the inner wall of the unit element.
[0004] The above patent can only meet the needs of short-distance use, and has a problem of limited effect on long-distance use such as high and far ends; therefore, it does not meet the existing needs, and a combined multifunctional telescopic rod for subway station maintenance is proposed.

[0023] The threaded hole 1011 can be connected to external tools such as a rake hook and a hoe with a stud. The external tools and the telescopic rod body are combined into a dredging component for cleaning narrow and long grooves, thereby improving the efficiency of manual cleaning of narrow spaces; the throat clamp 7 can firmly bind the motor 8 to the telescopic rod body, and then the motor 8 is connected to a cleaning brush to form a cleaning component for cleaning stains on the surface of high-altitude equipment such as speakers, so that the staff can clean the surface dirt of the high-altitude equipment directly on the ground, avoiding the safety hazards caused by personnel climbing up; the throat clamp 7 can also tie a probe with a camera function to the telescopic rod body. When a high-altitude equipment fails, the person on the ground sends the probe into the interior of the high-altitude equipment through the telescopic rod to assist the staff in troubleshooting the fault, thereby avoiding the delay that the staff need to set up special climbing equipment to troubleshoot the fault, thereby further improving work efficiency.
