Abstract
The utility model belongs to the technical field of hydraulic cylinders, in particular to a sealing and connecting structure of a hydraulic cylinder sleeve and cylinder cover. The sealing and connecting structure comprises a flange which is arranged on the outer side surface of the end of the cylinder sleeve, a flange which is arranged on the inner side surface of the cylinder cover and a bolt for connecting the cylinder cover on the cylinder sleeve; in addition, a conical surface is arranged around the flange; and the end surface of the cylinder sleeve is provided with another conical surface which is mutually matched and connected with the conical surface. The sealing and connecting structure of the hydraulic cylinder sleeve and cylinder cover has the advantages of simple structure, reliable sealing, convenient and quick detachment and installation.
Description
Technical field
The utility model belongs to the oil hydraulic cylinder technical field, relates in particular to the structure that is tightly connected of a kind of oil hydraulic cylinder cylinder sleeve and cylinder cap.
Background technique
Must guarantee during hydraulic cylinder works that oil hydraulic cylinder inside is in sealing state, otherwise not only oil hydraulic cylinder there is not thrust output, but also can be because leakage of oil and befouling environment.The cylinder sleeve of existing oil hydraulic cylinder can be connected with Sealing by flange with cylinder cap, and its linkage structure is on the outer side surface of cylinder sleeve end flange plate to be set, and cylinder cap is connected on the cylinder sleeve by above-mentioned flange plate and bolt.One all flanges are set on the inner side surface of above-mentioned cylinder cap, bury Sealing in the flange underground, thereby will be tightly connected between cylinder cap and the cylinder sleeve.This linkage structure is owing to used Sealing to make complex structure, and Sealing length service time can face problem aging and that change.Simultaneously, above-mentioned linkage structure has the shortcoming of dismounting inconvenience.
The model utility content
Technical problem to be solved in the utility model provides a kind of simple in structure, and sealing is reliable, makes things convenient for the structure that is tightly connected of the oil hydraulic cylinder cylinder sleeve and the cylinder cap of fast assembling-disassembling.
The utility model comprises the flange plate that is arranged on the outer side surface of cylinder sleeve end, be arranged on the flange on the cylinder cap inner side surface and above-mentioned cylinder cap is connected bolt on the cylinder sleeve; In addition, in described flange upper edge one week one conical surface is set; Another conical surface that cooperatively interacts and be connected with the above-mentioned conical surface is set on the end face of cylinder sleeve.
Compare with existing flange seal spare formula linkage structure, the self-styled of the structure that is tightly connected by the conical surface in the utility model seals oil hydraulic cylinder inside, not only makes hydraulic cylinder sealing reliable, and reduced Sealing, simple in structure, make things convenient for the oil hydraulic cylinder fast assembling-disassembling simultaneously.
Preferably, the tapering of above-mentioned two conical surfaces is respectively 1/5.
Description of drawings
Fig. 1 is the be tightly connected schematic representation of structure of cylinder sleeve and cylinder cap.
Embodiment
As shown in Figure 1, on the outer side surface of cylinder sleeve 1 end flange plate 1-1 is set, cylinder cap 2 is connected on the cylinder sleeve 1 by means of above-mentioned flange plate 1-1 and bolt 3.One all flange 2-1 are set on the inner side surface of described cylinder cap 2, one conical surface 2-2 are set in described flange 2-1 upper edge one week.Another conical surface 1-2 that cooperatively interacts and be connected with described conical surface 2-2 is set on the end face of described cylinder sleeve 1.Preferably, the tapering of above-mentioned conical surface 2-2 and another conical surface 1-2 is respectively 1/5.
Claims (2)
1. the structure that is tightly connected of oil hydraulic cylinder cylinder sleeve and cylinder cap, comprise the flange plate that is arranged on the outer side surface of cylinder sleeve end, be arranged on the flange on the cylinder cap inner side surface and above-mentioned cylinder cap is connected bolt on the cylinder sleeve, it is characterized in that: one conical surface is set in described flange upper edge one week; Another conical surface that cooperatively interacts and be connected with the above-mentioned conical surface is set on the end face of cylinder sleeve.
2. the structure that is tightly connected of oil hydraulic cylinder cylinder sleeve according to claim 1 and cylinder cap is characterized in that: the tapering of above-mentioned two conical surfaces is respectively 1/5.
