[0002] The cylinder housing end cover is one of the main accessories of the cylinder. A guide sleeve for being mounted on the piston rod and a convex ring for providing a support carrier for the sealing ring are installed on one side of the cylinder housing end cover. The existence of the convex ring and the guide sleeve makes one side of the cylinder housing end cover uneven. Therefore, the cylinder housing end covers cannot be stacked neatly after production. Therefore, most of the cylinder housing end covers are directly stored in the turnover basket. It is very inconvenient to take the disorganized cylinder housing end covers in the turnover basket. At the same time, the disorganized placement of the cylinder housing end covers affects the utilization rate of the internal space of the turnover basket. Utility Model Content

[0005] Furthermore, the edge of the pad facing away from the end cover body is recessed to form an annular groove, a thin iron ring is pasted in the annular groove, and a first magnet attracted to the thin iron ring is installed at the end of the limiting rod away from the pad.

[0006] Furthermore, the side of the limiting rod away from the pad is flush with the side of the end cover body away from the pad, the side of the limiting rod away from the pad is recessed to form a circular groove, and the first magnet is glued in the circular groove by glue.

[0007] Further, a thin iron sheet is pasted in the insertion slot through glue. The insertion post is of a hollow structure, and a second magnet adsorbed to the thin iron sheet is pasted on the side of the insertion post far from the cushion plate through glue.

[0008] Further, the cross-section of the insertion slot is rectangular, and the cross-section of the insertion post is rectangular.

[0009] Further, the cushion plate is a component made of a kind of plastic, and a plurality of weight-reducing holes are uniformly formed in one side surface of the cushion plate.

[0010] Further, a blind hole is formed by depression at the position where the cushion plate installs the limit rod, and one end of the limit rod is pasted in the blind hole.

[0011] Further, the lug and the end cover body are of an integrally formed structure, the convex ring and the end cover body are of an integrally formed structure, and the guide sleeve and the end cover body are of an integrally formed structure.

[0012] Advantages of the utility model:

[0013] 1. Make the guide sleeve fit with the cushion plate, and insert the four limit rods into the four counterbore holes respectively to realize the assembly of the cushion plate and the end cover body. At this time, the convex ring and the guide sleeve are between the end cover body and the cushion plate. Place the upper end cover body on the cushion plate where the lower end cover body is inserted, and insert the insertion post on the upper cushion plate into the insertion slot on the lower cushion plate to realize the neat stacking of the upper and lower layers of end cover bodies. And so on, complete the stable stacking of multiple end cover bodies, and finally realize the neat stacking of the end covers of the cylinder shell, which is beneficial to improving the utilization rate of the internal space of the turnover container.

[0014] 2. When the insertion post is inserted into the insertion slot, the second magnet on the insertion post is adsorbed to the thin iron sheet in the insertion slot, so as to prevent the insertion post from randomly disengaging from the insertion slot. At the same time, the stability of the stacking of the end cover bodies is improved, and the depth of the insertion slot is reduced as much as possible, that is, it is beneficial to reduce the thickness of the cushion plate. The insertion post and the insertion slot with rectangular cross-sections are adopted, so that the adjacent two layers of end cover bodies will not rotate relatively. After the cushion plate is separated from the end cover body, the cushion plate is recycled, which is convenient for the reuse of the cushion plate.

[0015] 3. After the end cover body and the cushion plate are alternately stacked to form a certain height, the first magnet in the limit rod on one cushion plate is adsorbed to the thin iron ring on another cushion plate, so that under the adsorption force of the first magnet and the thin iron ring, the side shift between the adjacent two layers of end cover bodies is prevented.
