The invention discloses a kind of anti-loosing type oil cylinder cover structure, comprise cylinder body, cylinder cap and piston rod, described cylinder cap comprises insertion tube and the flange plate of coaxial connection, described insertion tube is inserted and the outer wall of described insertion tube and described inboard wall of cylinder block gluing, sealing from described cylinder body one end, described flange plate diameter is corresponding with described cylinder body external diameter, described cylinder body end face is distributed with some tapped holes, described flange plate is provided with through hole with the corresponding position of each described tapped hole, screw coordinates with described tapped hole through described through hole, described side of cylinder block is provided with a tapped through hole, a slotted eye corresponding with this tapped through hole position is provided with in described insertion tube side, holding down bolt coordinates with described tapped through hole and inserts in described slotted eye.A kind of anti-loosing type oil cylinder cover of the present invention structure, avoids oil cylinder cover and oil cylinder joint to loosen, and then avoids the damage to equipment that brings thus.
Description
Technical field
The present invention relates to oil cylinder accessory manufacturing technology field, especially a kind of anti-loosing type oil cylinder cover structure.
Background technique
Oil cylinder cover is normally threaded with the connection of oil cylinder, internal thread established by oil cylinder, 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, and traditional pin fixed oil cylinder lid and oil cylinder are only fixed on one point, produce larger, once thread looseness on one point by larger single force, can cause damage to part.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of anti-loosing type oil cylinder cover structure, avoid oil cylinder cover and oil cylinder joint to loosen, and then avoid the damage to equipment that brings thus.
In order to realize foregoing invention object, the invention provides following technological scheme:
A kind of anti-loosing type oil cylinder cover structure, comprises gray iron and piston rod,
Described cylinder cap comprises insertion tube and the flange plate of coaxial connection, described insertion tube is inserted and the outer wall of described insertion tube and described inboard wall of cylinder block gluing, sealing from described cylinder body one end, described flange plate diameter is corresponding with described cylinder body external diameter, described cylinder body end face is distributed with some tapped holes, described flange plate is provided with through hole with the corresponding position of each described tapped hole, screw coordinates with described tapped hole through described through hole
Described side of cylinder block is provided with a tapped through hole, and be provided with a slotted eye corresponding with this tapped through hole position in described insertion tube side, holding down bolt coordinates with described tapped through hole and inserts in described slotted eye.
Further, described holding down bolt comprises screw rod and nut, and described nut is boss shape, and the less side end face of described head diameter is connected with described screw rod,
The appearance bore dia of described tapped through hole outside is corresponding with the external diameter of described nut, between the outside and described appearance hole of the less part of described head diameter, be provided with sealing gasket.
A kind of anti-loosing type oil cylinder cover of the present invention structure, avoids oil cylinder cover and oil cylinder joint to loosen, and then avoids the damage to equipment that brings thus.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of anti-loosing type oil cylinder cover structure of the present invention.
