When this kind of air cylinder is used for several years, failure will appear. Common failures mainly have three kinds: 1, piston rod throat seal ring failure, serious air leakage;2, the O-ring of the upper cavity of the cylinder body worn on the end cover;3, the rubber piston on the piston rod worn.

[0003] When one of the above three common failures appears, it means that the air cylinder has been damaged and cannot meet the production needs. After the faulty air cylinder is removed from the equipment, it is found that the vulnerable parts cannot be directly replaced, and only the cylinder body, end cover and piston rod can be separated by breaking. But at this time, it also means that the air cylinder is damaged and has no value. Through the analysis and research on the internal structure of the air cylinder, in order to replace the vulnerable parts without damaging the air cylinder, the disassembly and assembly can meet the requirements of normal use after replacing the vulnerable parts, and also save the cost of spare parts procurement.

[0025] Figure 1 is a schematic structural diagram of the detachable air cylinder, as Figure 1 indicated, and referring to Figures 2 to 6 , the utility model provides a detachable air cylinder, detachable air cylinder includes cylinder body 100 and cylinder cover 200. The inner wall of cylinder body 100 is provided with limit slot 110, and cylinder body 100 is provided with a plurality of dismounting holes 120, and the dismounting hole 120 extends along the radial direction of cylinder body 100 and penetrates the inner wall of cylinder body 100. The dismounting hole 120 is communicated with the limit slot 110.

[0026] Cylinder cover 200 includes lower cover body 240 inserted into cylinder body 100 and upper cover body 230 located outside cylinder body 100, and snap spring groove 210 is arranged on lower cover body 240. When the lower cover body 240 is inserted into the cylinder body 100, the snap spring groove 210 is communicated with the limit slot 110, and the limit snap spring 220 is sleeved on the snap spring groove 210, and the limit snap spring 220 can be inserted into the snap spring groove 210 and the limit slot 110 at the same time.

[0027] Specifically, the limit snap spring 220 is provided with a notch, which can provide the snap spring with expansion or contraction space. When the inner circle end of the limit snap spring 220 is inserted into the snap spring groove 210 and the outer circle end is inserted into the limit slot 110, the limit snap spring 220 makes the cylinder cover 200 clamped on the cylinder body 100. Further, the cylinder cover 200 needs to be dismounted from the cylinder body 100, and the outer circle end of the limit snap spring 220 needs to be pressed inward, so that the outer circle end of the limit snap spring 220 is separated from the limit slot 110, and therefore the groove depth of the snap spring groove 210 is at least equal to the width of the snap spring. The dismounting hole 120 can make the construction personnel apply inward pressure to the limit snap spring 220 from the outside, so that the limit snap spring 220 completes the inward shrinkage deformation, to facilitate the dismounting of the cylinder cover 200 from the cylinder body 100. Therefore, the dismounting hole 120 can quickly complete the dismounting of the air cylinder, avoid the air cylinder to be broken and disassembled, greatly reduce the difficulty of replacing the vulnerable parts in the air cylinder. At the same time, it can meet the normal use of the air cylinder after replacing the vulnerable parts, save the procurement cost of spare parts.

[0028] When the cylinder cover 200 needs to be detached from the cylinder body 100, the worker inserts tools into the plurality of detachable holes 120 simultaneously, and applies pressure to the axial center of the cylinder body 100 along the radial direction of the cylinder body 100. The limiting snap spring 220 is contracted inward under the action of the pressure, so that the outer circular end of the limiting snap spring 220 is separated from the limiting groove 110 and is inserted into the snap spring groove 210. At the same time, the cylinder cover 200 is connected with a puller tool, and when the outer circular end of the limiting snap spring 220 is separated from the limiting groove 110, the puller tool pulls the cylinder cover 200 outward from the cylinder body 100, and the detachment of the cylinder is completed.

[0029] In the embodiment, as shown in Figure 2 and Figure 4 , the detachable cylinder further comprises a piston 300 and a plug column 310. The plug column 310 is slidingly inserted into the cylinder cover 200. The piston 300 is fixed to the lower end of the plug column 310, and the inner wall of the piston 300 is in sealing contact with the inner wall of the cylinder body 100. The puller tool is connected to the upper end of the plug column 310.

[0030] In some embodiments of the utility model, as shown in Figure 3 and Figure 5 , the lower cover body 240 is further provided with a sealing groove 250, and the sealing groove 250 is arranged below the snap spring groove 210. The sealing ring 260 is sleeved on the sealing groove 250.

[0031] Specifically, the sealing ring 260 is made of rubber material, and the outer circular end is in contact with the inner wall of the cylinder body 100. The sealing groove 250 is arranged below the snap spring groove 210, so that the sealing ring 260 is located below the limiting snap spring 220. When the cylinder cover 200 is installed on the cylinder body 100, the sealing ring 260 still keeps the cylinder cover 200 and the cylinder body 100 in a sealed state, avoiding the leakage phenomenon caused by the arrangement of the detachable hole 120.

[0032] In some embodiments of the utility model, as shown in Figure 1 , the number of detachable holes 120 is at least three, and a plurality of detachable holes 120 are uniformly distributed along the circumference of the cylinder body 100. Specifically, the number of detachable holes 120 is preferably four.

[0033] In some embodiments of the utility model, as shown in Figure 2 and Figure 4 , the bottom of the cylinder body 100 is provided with a fixing block 140. The fixing block 140 is provided with a detachable screw 130, and the detachable screw 130 extends along the axial direction of the cylinder body 100. Specifically, the detachable screw 130 is provided with a thread, and the detachable screw 130 can be arranged to fix the cylinder body 100 at a predetermined position by thread connection, so as to facilitate the puller tool to apply tension to the cylinder cover 200, and promote the separation of the cylinder cover 200 and the cylinder body 100.

[0034] Thus far, those skilled in the art will recognize that while the present application has been shown and described herein in terms of a few illustrative embodiments, numerous other variations or modifications could be determined or deduced from the disclosure of the present application without departing from the spirit or scope of the present application. Accordingly, the scope of the present application should be understood and appreciated to cover all such other variations or modifications as well.
