When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

As shown in Fig. 1 and Fig. 3, the simple assembly and disassembly device of the hydraulic oil filter cylinder provided by the present invention is used for manually disassembling and assembling the oil filter cylinder, so as to facilitate the replacement of the hydraulic oil filter element. The simple assembly and disassembly device of the hydraulic oil filter cylinder may include a base 1 , a support column 2 , a rotating cylinder 3 and a plug 4 .

The base 1 can adopt various suitable structural shapes. When placed on the water surface, the base 1 usually has upper and lower surfaces parallel to the water surface.

The support column 2 is vertically and fixedly arranged on the base 1 , which specifically means that the axis of the support column is parallel to the upper and lower surfaces of the base 1 . In addition, external threads are provided on the outer ring surface of the support column 2 along the axis direction (the up-down direction in FIG. 1 ).

On the inner ring surface of the rotating cylinder 3, there is a thread segment (not shown) that matches the external thread of the support column 2 along the axis direction (up and down in FIG. 1 ); furthermore, the starting point of the thread segment is located at the rotating cylinder 3 One of the axial end faces (the lower end in Fig. 1), that is, the thread is gradually opened upwards from the lower end face in the illustration; and the height of the threaded section in the axial direction of the rotating cylinder 3 is less than that Height, that is, the thread is opened to a distance from the top end face. The rotating cylinder 3 is slidably sleeved on the support column 2 from the starting point of the threaded section (connected by the matching internal and external threads), so that the rotating cylinder 3 and the support column 2 form a spiral lifting motion pair.

The plug 4 is annular, and is fixedly arranged on one end of the rotating cylinder 3 that is not provided with threads (the top in FIG. 1 ). The axis of the plug 4 coincides with the axis of the rotating cylinder 3. Rotate around its axis; and, the profile of the inner ring surface of the plug block 4 matches the external profile of the pre-matching part at the bottom of the hydraulic oil filter cartridge. Among them, the pre-matching part at the bottom of the hydraulic oil filter cylinder can be selected according to the hydraulic oil filter structure of different models, for example, it can be a hexagonal structure outside the bottom end of the hydraulic oil filter.

In the simple assembly and disassembly device of the hydraulic oil filter cylinder of the present invention, the rotating cylinder 3 drives the oil filter cylinder to rotate and lift together through the replaceable plug 4 installed on its top, so as to realize the disassembly and assembly of the oil filter cylinder, and the structure is simple , easy to operate, small in size and strong in versatility, can significantly reduce the labor intensity of workers and improve their labor efficiency.

In the simple assembly and disassembly device of the hydraulic oil filter cylinder of the present invention, the base 1 can be specifically a square pedal, and a rectangular through hole is opened on the pedal, and the end of the support column 2 away from the rotating cylinder 3 is hinged on the cylinder through a cylindrical pin 11. In the rectangular through hole, and the axis of cylindrical pin 11 is parallel with pedal. Wherein, when the support column 2 shows the state (perpendicular to the pedal), the operator can step on the pedal, and then give the support column 2 a vertical downward force through the cylindrical pin 11, thereby stabilizing the support column 2. The stability of the whole device is improved. In addition, after the disassembly and assembly are completed, the pedal and the support column 2 can also be folded around the cylindrical pin 11 to facilitate movement.
