Description

Technical Field

[0001] The utility model relates to the technical field of environmental sanitation cleaning, in particular to a cleaning brush. Background Art

[0002] Urban environmental sanitation has evolved along with human social life, and today's social environment is constantly subject to human change. Urban environmental sanitation issues have become a problem in the process of natural ecosystems transforming into human ecosystems. Due to the rapid population growth and urban concentration, issues such as drinking water hygiene, waste disposal, and environmental pollution must be planned, designed, and controlled using scientific methods to make the environment suitable for human life and promote modern civilization: to ensure that all people have a healthy standard of living and realize their natural right to health and longevity. The International Junyou Association believes that the causes of environmental sanitation deterioration are mostly man-made. Therefore, cultivating the public's sense of public morality should also be the most meaningful and effective way to improve environmental sanitation, and the sweeping brush is one of the most effective cleaning tools for roads.

[0003] Traditional sanitation cleaning brushes have the following defects in daily use:

[0004] 1. The traditional sanitation cleaning brush has a relatively simple function and can only clean the garbage on the city roads. If there are sticky objects on the city roads, the cleaning brush alone cannot clean them up;

[0005] 2. The length of the traditional sanitation cleaning brush cannot be adjusted, and cannot be adjusted according to the body shape of the sanitation worker, and the practicality is low. Therefore, we propose a new type of cleaning brush. Utility Model Content

[0006] The utility model provides a cleaning brush to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A cleaning brush comprises a cleaning broom, a placement cavity is provided inside the cleaning broom, a cleaning scraper is slidably connected inside the placement cavity, a pressing spring is fixedly installed inside the cleaning scraper, a clamping column is fixedly installed on one end of the pressing spring, a clamping column hole is provided on the outside of the cleaning broom, a threaded rod is rotatably connected to the upper side of the cleaning broom, an adjusting cylinder and a mother cylinder are threadedly connected to the outside of the threaded rod from bottom to top, an upper limit ring and a lower limit ring are fixedly installed on the outside of the adjusting cylinder in sequence from top to bottom, a rotating ring is rotatably connected to the outside of the adjusting cylinder, a linkage rod is rotatably connected to the outside of the rotating ring, a grip rod is fixedly installed on one end of the mother cylinder, and a sleeve is sleeved on the outside of the grip rod.

[0009] As a further improvement of the technical solution: an anti-slip plate is fixedly installed at one end of the cleaning scraper and the clamping column.

[0010] As a further improvement of the technical solution, the diameter of the clamping column hole is larger than the diameter of the clamping column.

[0011] As a further improvement of the technical solution: the rotating ring is located between the upper limit ring and the lower limit ring.

[0033] The working principle of the utility model is as follows: when using the urban road cleaning brush, first adjust the length of the cleaning brush according to the height of the sanitation worker, hold the threaded rod 7 with one hand, and rotate the mother cylinder 9 with the other hand to adjust the relative length of the mother cylinder 9 and the threaded rod 7, so that it is convenient for sanitation workers of different heights to use it, and it is highly practical. When it is necessary to adjust the angle of the cleaning sweep 1 of the urban road cleaning brush, rotate the adjustment cylinder 8, and the linkage rod 13 moves to achieve the effect of adjusting the inclination angle of the cleaning sweep 1, which is convenient for daily cleaning operations on urban roads. When there is sticky matter attached to the urban road, manually press the clamping column 5 inwardly, and the clamping column 5 shrinks inwardly, so that the clamping column 5 is separated from the clamping column hole 6, and the cleaning scraper 3 can be moved, and a part of the cleaning scraper 3 is moved out of the placement cavity 2. When the cleaning scraper 3 moves to the specified position, the clamping column 5 will pop up under the action of the pressing spring 4, and be clamped in the clamping column hole 6, and the adjustment of the cleaning scraper 3 is completed. At this time, the sharp end of the cleaning scraper 3 can be used to remove the sticky matter attached to the ground.

[0034] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above.
