Description

Technical Field

[0001] This utility model relates to the field of glass cleaning technology, specifically a multi-purpose adjustable glass cleaning tool for subway vehicles. Background Technology

[0002] The cleaning of subway cars is directly related to the core safety of train operation. It is an important barrier for passengers to obtain information and ensure safety in emergency situations, significantly improves the comfort and satisfaction of daily travel, helps protect vehicle assets, reduces long-term maintenance costs, and is an important window to showcase the good image of the city and enterprises. In the process of cleaning subway cars, the cleaning of the car windows is particularly important and is also the focus of complaints.

[0003] Currently, after the vehicle exterior is cleaned, the windows are manually wiped with towels to remove any remaining dirt and watermarks, or wiped clean with a squeegee. During the wiping process, watermarks and dirt may remain on the glass even after it has dried. In this case, a damp towel is used to wipe it, but watermarks will still appear after it dries. Using both towels and squeegees is time-consuming, labor-intensive, and inefficient.

[0004] Chinese patent discloses a glass wiping device (authorization announcement number CN204931564U). This patented technology wets the glass with a damp cloth, removes residual moisture with a rubber scraper, and then dries the glass with a dry cloth. At the same time, it can also absorb dust during the wiping process through a dust inlet to prevent it from adversely affecting the health of the workers. However, it cannot control the humidity of the dry cloth and is inconvenient for wiping glass at high places. Utility Model Content

[0022] Please see Figures 1-6In this embodiment of the invention, a multi-purpose adjustable subway car glass cleaning tool includes several levers 1 slidably connected together, with a hand-tightening bolt 9 engaged between each pair of adjacent levers 1. Loosening the hand-tightening bolt 9 counterclockwise adjusts the length between two levers 1, while tightening it clockwise ensures the two levers 1 are securely fixed together without slippage. When the cleaner is standing on a platform, the length between the hand-tightening bolts 9 can be shortened, allowing the cleaner to clean the subway car glass with the shorter lever. When the cleaner is standing on the ground, the length between the hand-tightening bolts 9 can be extended, allowing the cleaner to clean the subway car glass with the longer lever. Connecting rods are fixedly connected to the uppermost lever 1. A handle 2 is fixedly connected to a handle 1 at the top and bottom of a connecting rod 3 and a connecting rod 8. A rotary joint 4 is installed at one end of the connecting rod 3, and a cleaning roller assembly 5 is installed at one end of the rotary joint 4. A rotary joint 7 is installed at one end of the connecting rod 8, and a wiper 6 is installed at one end of the rotary joint 7. The angles of the cleaning roller assembly 5 and the wiper 6 relative to the glass can be adjusted by using rotary joints 4 and 7 respectively, so that dirt can be wiped away and water stains can be wiped away in one go during cleaning. The position between the cleaning roller assembly 5 and the wiper 6 is adjustable, that is, the cleaning roller assembly 5 is installed on the rotary joint 7 and the wiper 6 is installed on the rotary joint 4, so as to meet the needs of different cleaning methods, such as wiping from top to bottom or from bottom to top.

[0023] exist Figure 2 , Figure 3 and Figure 4In the cleaning roller assembly 5, there is a roller shell 510 and a cleaning cloth 57 sleeved on the outside of the roller shell 510. A hollow shaft 58 is installed through the inner side of the roller shell 510, and a set of bearings 514 is installed between the roller shell 510 and the hollow shaft 58. The roller shell 510 and the cleaning cloth 57 can rotate around the hollow shaft 58 through the bearings 514 to wipe the glass. Threaded grooves 513 are opened at both ends of the hollow shaft 58 near the roller shell 510. A nut plate 511 is engaged with the hollow shaft 58. A roller frame 51 is fixedly connected to the outer side of the hollow shaft 58 via a set of nut plates 511. A connector rod 54 is fixedly connected to one end of the roller frame 51. A clamp 55 is fixedly connected to one end of the connector rod 54. A spring post 56 is installed at both the upper and lower ends of the clamp 55. A water inlet 512 is provided at one end of the hollow shaft 58. Several overflow holes 59 are opened on the outer side of both the hollow shaft 58 and the roller shell 510. Water is introduced through the water inlet 512 via a flexible hose. Connected to an external miniature water pump, which is placed inside a water tank, the system draws water from the tank into the hollow shaft 58. The water then seeps through the overflow hole 59 onto the cleaning cloth 57, keeping it evenly moist. This moistened cloth is used to wipe the subway car windows, eliminating the need to submerge the cloth in the water tank, which would otherwise lead to uncontrolled water flow and secondary contamination if the cloth becomes too wet and drips. Both ends of the outer side of the cleaning cloth 57 are equipped with elastic rings 52, which can tighten the cleaning cloth 57 to the roller shell 510 to prevent it from slipping off. Both ends of the roller frame 51 are provided with locking grooves 53, and the hollow shaft 58 is fixedly engaged in the locking grooves 53 by the nut piece 511. Therefore, when the threaded groove 513 is loosened counterclockwise, the hollow shaft 58, the roller shell 510 and the cleaning cloth 57 can be removed together, which makes it convenient to replace the clean cleaning cloth 57.

[0024] exist Figure 1 and Figure 5In this device, the rotary joint 4 includes a movable rod 41 and a fixed rod 45 that matches the movable rod 41. A connecting sleeve 44 is installed at one end of the movable rod 41, and a rotating groove 43 is provided at the other end of the movable rod 41. The rotary joint 4 can be fixed to the connecting rod 3 through the connecting sleeve 44. A shaft lug 42 is fixedly connected to one end of the movable rod 41, and a positioning hole matching the clamp head 55 and the spring post 56 is provided at the other end of the movable rod 41. By inserting the clamp head 55 and the spring post 56 into the corresponding positioning hole, the cleaning roller assembly 5 can be installed on the rotary joint 4, and the cleaning roller assembly 5 can be pulled out directly from one end of the rotary joint 4. A fastening screw 46 is provided through the rotating groove 43 and the shaft lug 42. By loosening the fastening screw 46 counterclockwise, the angle between the fixed rod 45 and the movable rod 41 can be adjusted, thereby adjusting the angle of the cleaning roller assembly 5 for the convenience of cleaning personnel.

[0025] exist Figure 1 and Figure 6 In this assembly, the wiper 6 includes a wiper frame 61, with a scraper 65 embedded at one end of the frame 61 and a connector rod 62 fixedly connected to the other end. A set of hand-tightening bolts 66 are embedded between the wiper frame 61 and the scraper 65. By loosening the hand-tightening bolts 66 counterclockwise, the scraper 65 can be removed and replaced with a new one. A clamp 63 is fixedly connected to one end of the connector rod 62. Spring posts 64 are installed at both the upper and lower ends of the clamp 63. Since the structure of the rotary joint 4 corresponds to that of the rotary joint 7, the wiper 6 can be installed on the rotary joint 7 by inserting the clamp 63 and the spring posts 64 into one end of the rotary joint 7. Therefore, the cleaning roller assembly 5 and the wiper 6 can be interchanged. At the same time, the angle of the wiper 6 can be adjusted through the rotary joint 7 to meet the needs of on-site cleaning.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
