Description of the drawings
Better embodiment schematic diagrams of the Fig. 1 for the quick detachable hydraulic damping device of this utility model.
Structural representations of the Fig. 2 for the quick detachable hydraulic damping device of this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As depicted in figs. 1 and 2, a kind of quick detachable hydraulic damping device, including threaded body 1 and core body 2, threaded body 1
Outside is provided with screw thread, and for this utility model is fixed on the machine, used as the buffer unit of machine, 1 one end of threaded body is
Blind end, the outside of blind end are installed with the nut 11 of hexagon, for this utility model being rotated into corresponding using spanner
Place is fixed.
As shown in Fig. 2 core body 2 is threadedly coupled inside threaded body 1 and with threaded body 1, the outside of 2 lower end of core body
Hexagon is shaped as, for core body 2 is screwed in threaded body 1, upper end and the blind end of threaded body 1 of core body 2 are abutted against,
Seal washer 21 is provided with abutting, for ensureing the sealing between threaded body 1 and core body 2；
Helicla flute piston 4 and oil sealing 6 are provided with core body 2, are formed between the blind end and helicla flute piston 4 of threaded body 1
First oil storage space, is provided with back-moving spring 3 in the first oil storage space, form the second oil storage empty between helicla flute piston 4 and oil sealing 6
Between, be provided with connecting rod 5 between helicla flute piston 4 and oil sealing 6, helicla flute piston 4 is provided with helicla flute, spiral fluted shape by
Diminish greatly, core body 2 is fixedly provided with logical oil portion 12, logical oil portion 12 is provided with annular groove 13, and logical oil portion 12 is arranged on helicla flute
At piston 4, the first oil storage space is mutual only by the gap that annular groove 13 and helicla flute are collectively forming with the second oil storage space
It is logical, full hydraulic oil is stored in the first oil storage space and the second oil storage space, if helicla flute piston 4 is from the second oil storage space to the
One oil storage space is moved, and the gap that the hydraulic oil in the first oil storage space can be collectively forming by annular groove 13 and helicla flute leads to
Second oil storage space, with the movement of helicla flute piston 4, gap becomes less and less, until after very close to each other, helicla flute piston 4 is not
The movement of the first oil storage space of phase direction can be continued；
Oil sealing 6 is provided with two sealing rings 61, and for the second oil storage space of dual-seal, so as not to oil leak, oil sealing 6 is supported
Pre-compressed spring 7 is connected to, pre-compressed spring 7 abuts prefabricating plate 8, needs the part of buffering to abut against with prefabricating plate 8, pressure is acted on first
On prefabricating plate 8.
During use, the nut 11 of hexagon fixed in threaded body 1 is blocked with spanner, this utility model is passed through into screw thread
The mode of screw-in is fixed on the machine where fixed buffer unit, adjusts this utility model by adjusting length of fit
Installation site；During machine operation, need buffering part be connected on prefabricating plate 8, part press prefabricating plate 8 after pressure successively
Act on pre-compressed spring 7, oil sealing 6, connecting rod 5 and helicla flute piston 4 so as to promote helicla flute piston 4 by the second oil storage space
Move to the first oil storage space direction, the hydraulic oil in the first oil storage space can be collectively forming by annular groove 13 and helicla flute
Gap leads to the second oil storage space, with the movement of helicla flute piston 4, the gap between helicla flute piston 4 and annular groove 13
Become less and less, the resistance of the movement of helicla flute piston 4 linearly increases, until after very close to each other, helicla flute piston 4 can not continue phase
First oil storage space direction is moved, so as to reach linear buffer purpose；After the completion of buffering, due to the effect of back-moving spring 3, spiral shell
Spin slot piston 4 returns to initial position again.
After this utility model life-time service, the rubber components in device such as seal washer 21 and sealing ring 61, unavoidable meeting
Sealing property is greatly reduced because of oxidation, sealing property is bad just not to have good buffering effect, due to oil sealing 6 and even
Connection is usually fixed between bar 5, and sealing ring 61 is provided separately within oil sealing 6, it is possible to be about to certainly this practicality new
Type is dismantled, the seal washer 21 that only more need to renew and sealing ring 61, need not because be difficult to ensure that sealing and by 6 He of oil sealing
Connecting rod 5 is together changed, and greatlys save resource, reduces use cost.This utility model is quick detachable, can be with convenient use person certainly
Row maintenance, additionally it is possible to ensure the good airproof performance after maintenance.
Embodiment of the present utility model is these are only, the scope of the claims of the present utility model, every profit is not thereby limited
The equivalent structure made with this utility model description and accompanying drawing content, is directly or indirectly used in other related technology necks
Domain, in the same manner within scope of patent protection of the present utility model.
