Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing。Wherein identical parts are presented with like reference characters。It should be noted that the word "front", "rear" of middle use is described below, direction that "left", "right", "up" and "down" refer in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center。
As shown in Fig. 2-3 and Fig. 5, the hydraulic support column that this utility model one embodiment provides, including outer cylinder 1, the inner cylinder tube 2 being slidably disposed in outer cylinder 1 and the post alive 3 that is slidably disposed in inner cylinder tube 2, at the inner cylinder tube cylinder mouth of inner cylinder tube 2 and live and be provided with built-in pilot sleeve 4 between post。
Being connected to external pilot sleeve 5 on the outer cylinder cylinder mouth 11 of outer cylinder 1, external pilot sleeve 5 is arranged on inner cylinder tube 2。
That is to say, this hydraulic support column is mainly made up of outer cylinder 1, inner cylinder tube 2, live post 3, built-in pilot sleeve 4 and external pilot sleeve 5。
Inner cylinder tube 2 is slidably disposed in outer cylinder 1, and post 3 of living is slidably disposed in inner cylinder tube 2, and when needed, inner cylinder tube 2 and post 3 of living can stretch out for supporting。
In order to seal between inner cylinder tube 2 and post 3 alive, between inner cylinder tube cylinder mouth and post alive, it is provided with built-in pilot sleeve 4。
In order to be connected and sealed between outer cylinder 1 and inner cylinder tube 2, and avoid outer cylinder cylinder mouth erosion corrosion, cylinder barrel and mouth 11 be connected to external pilot sleeve 5 outside, external pilot sleeve 5 is socketed on inner cylinder tube 2。
So, by cylinder barrel and mouth 11 outside connects external pilot sleeve, play a protective role, it is to avoid the abrasion of outer cylinder cylinder mouth and corrosion。Further, when maintenance, it is only necessary to pull down external pilot sleeve, can keep in repair by external cylinder barrel and mouth, simple。
