Description

Technical Field

[0001] The utility model relates to a garbage truck, in particular to an oil cylinder for the garbage truck. Background Art

[0002] Cleaning, greening and beautification of cities are very important. With the development of cities, the workload of cleaning garbage on urban roads and streets is also increasing. At present, in some large and medium-sized cities, sanitation garbage trucks have been gradually used to replace traditional manual cleaning. The sweeping arm on the garbage truck is swung out and retracted by the oil cylinder. During the cleaning operation, the piston rod of the oil cylinder extends, the sweeping arm swings out, and the sweeping disc starts to work; when driving, the piston rod of the oil cylinder drives the sweeping disc to retract and lock to ensure driving safety.

[0003] Since there is a lot of dust in the operating environment of the garbage truck, it is easy for a lot of dust to adhere to the surface of the oil cylinder of the garbage truck when it is used. In addition, after a long period of use, the dustproof pad inside the oil cylinder is easily damaged, thus affecting the normal use of the garbage truck. Summary of the invention

[0004] The purpose of the utility model is to provide a hydraulic cylinder for a garbage truck to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a cylinder for a garbage truck, comprising a cylinder body, a mounting cover and a mounting ring, wherein a mounting cover is provided on one side of the cylinder body, and a mounting ring is provided on a side of the mounting cover away from the cylinder body.

[0006] Preferably, a piston rod is provided inside the cylinder body, a piston body is provided on one side of the piston rod, an oil inlet is opened inside the mounting cover, a dust ring is provided on one side of the mounting cover close to the oil inlet, and a locking block is connected to one side of the dust ring.

[0007] Preferably, a movable frame is connected to one side of the locking block, a limiting spring is connected to a side of the movable frame away from the locking block, and an adjusting block is connected to a side of the movable frame close to the limiting spring.

[0008] Preferably, a push block is provided inside the adjusting block, one side of the push block is connected to a threaded rod, and the side of the threaded rod away from the push block is connected to a hexagon socket bolt.

[0009] Preferably, an oil storage block is provided inside the mounting ring, an oil filling brush is connected to the bottom of the oil storage block, and a connecting rod is connected to a side of the oil storage block away from the oil filling brush.

[0010] Preferably, a push plate is connected to one side of the connecting rod, an oil storage tank is provided inside the oil storage block, and a sealing cover is connected to the top of the push plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the utility model is used on the surface of a garbage truck, the hexagonal bolt is rotated by a hexagonal tool, driving the threaded rod connected on one side to rotate in the threaded groove and move at the same time, and the threaded rod drives the push block connected on one side to move, so that the push block is quickly separated from the adjustment block, so that the limiting spring is reset and the moving frame is pulled, and the moving frame drives the connected locking block to move, so that the locking block is separated from the dust ring, so that the dust ring can be quickly disassembled and replaced to ensure the normal use of the garbage truck;

[0013] 2. By pressing the push plate, the push plate drives the connecting rod connected on one side to move, thereby pushing the oil storage block connected below, and the oil storage block drives the oil filling brush connected at the bottom to move, so that the oil filling brush can lubricate the installation place of the utility model and the garbage truck, thereby preventing the installation place from rusting and ensuring that the utility model can be smoothly adjusted on the surface of the garbage truck. In addition, the sealing cover can be taken out to add lubricating oil. BRIEF DESCRIPTION OF THE DRAWINGS
