Abstract
The invention discloses an oil cylinder cover anti-loose structure in an oil cylinder. An annular bulge is formed in a cylinder body of the oil cylinder; a first end surface of the annular bulge faces the end for mounting an oil cylinder cover; the cross section of the first end surface and the cross section of the oil cylinder body are in the same plane; a second end surface of the annular bulge is far away from the end for mounting the oil cylinder cover and is an annular inclined surface; and the second end surface is gradually shrunk from inner side of the oil cylinder body to the end for mounting the oil cylinder cover. The oil cylinder cover anti-loose structure can effectively locks the oil cylinder and the oil cylinder cover, and is convenient to disassemble, and production safety and normal operation are effectively ensured.
Description
Technical field
The present invention relates to a kind of locking device technical field, especially oil cylinder inner cylinder lid anti-loose structure.
Background technique
Oil cylinder cover is normally threaded with the connection of oil cylinder, and internal thread established by oil cylinder, and oil cylinder cover establishes outside thread, under the effect of pressure oil, the situation that being threaded between cylinder barrel with cylinder cap likely occurs to loosen and cause cylinder cap to come off, therefore, is necessary to take certain locking measure.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose oil cylinder inner cylinder lid anti-loose structure, can effectively oil cylinder and oil cylinder cover be locked, and easy disassembly, effectively ensure that the safety of production and normal operation.
In order to realize foregoing invention object, the invention provides following technological scheme:
Oil cylinder inner cylinder lid anti-loose structure, is provided with annular protrusion in described cylinder block inside,
First end face of described annular protrusion is towards installation oil cylinder cover one end end face, itself and described cylinder block cross section herein in same plane,
Second end face of described annular protrusion is the end face away from described installation oil cylinder cover one end, and it is annular slope, and described second end face inwardly shrinks from the inner side of described cylinder block gradually to described installation oil cylinder cover one end.
Further, what connect described first end face of described annular protrusion and described second end face is the 3rd end face, has circular groove, establish Stamping Steel Ribbon in described circular groove along described 3rd end.
Further, after described oil cylinder cover is installed, between described first end face and described oil cylinder cover end face, be provided with tension structure.
The present invention proposes oil cylinder inner cylinder lid anti-loose structure, by the design to annular protrusion, can effectively barrier oil pressure to the direct effect of oil cylinder cover, and to the design of the second end face achieve to oil pressure effectively excessively, avoid oil pressure to vertical surface direct effect, cause annular protrusion and cylinder block joint to damage, the present invention effectively ensure that the safety of production and normal operation.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of oil cylinder inner cylinder lid anti-loose structure of the present invention;
Fig. 2 is the close-up schematic view at annular protrusion place of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
Oil cylinder inner cylinder lid anti-loose structure as shown in Figure 1-2, is provided with annular protrusion 6 in cylinder block 1 inside,
First end face 61 of annular protrusion 6 is towards installation oil cylinder cover one end end face, itself and cylinder block 1 cross section herein in same plane,
Second end face 62 of annular protrusion 6 is the end face away from installing oil cylinder cover one end, and it is annular slope, and the second end face 62 inwardly shrinks gradually from the inner side of cylinder block 1 to installation oil cylinder cover one end.
What connect the first end face 61 of annular protrusion 6 and the second end face 62 is the 3rd end face 63, has circular groove 64, establish Stamping Steel Ribbon 2 in circular groove 64 along the 3rd end.
After oil cylinder cover is installed, between the first end face 61 and oil cylinder cover end face, be provided with tension structure.
Oil cylinder inner cylinder lid anti-loose structure of the present invention, by the design to annular protrusion, can effectively barrier oil pressure to the direct effect of oil cylinder cover, and to the design of the second end face achieve to oil pressure effectively excessively, avoid oil pressure to vertical surface direct effect, cause annular protrusion and cylinder block joint to damage, the present invention effectively ensure that the safety of production and normal operation.
