Description
Technical field
The utility model relates to a kind of compact type telescopic oil cylinder.
Background technique
Oil cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional, and can convert hydraulic energy to mechanical energy.Common oil cylinder piston energy accomplish linear to-and-fro motion, the straight-line displacement of output is limited.And, when some special occasions need to long shift length, needing to manufacture the oil cylinder of extension length, requirements of installation space is larger
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of longer telescopic oil cylinder of the compact type apart from traveling priority of realizing in limited length is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of compact type telescopic oil cylinder, comprise cylinder body, cylinder bottom with the cylinder body integrative-structure, be arranged on piston rod and the piston that is located at the piston rod rearward end in cylinder body, be provided with inner cylinder tube between cylinder body and piston rod, be provided with the first guide sleeve between cylinder body front inner wall and inner cylinder tube, inner cylinder tube rear end and inboard wall of cylinder block are slidably matched, inner cylinder tube front end and the first guide sleeve are slidably matched, be provided with the second guide sleeve between inner cylinder tube front end and piston rod, piston and inner cylinder tube rear end are slidably matched, piston rod front end and the second guide sleeve inwall are slidably matched, the nearly piston nose face of piston rod place is provided with cushion collar.
Described inner cylinder tube rear end and inboard wall of cylinder block cooperation place are provided with the first guide ring, and piston and inner cylinder tube inwall cooperation place are provided with the second guide ring.
Be provided with dust ring in the first guide sleeve, in described the second guide sleeve, be provided with buffer ring.
The beneficial effects of the utility model are: the utility model compact structure, by inner cylinder tube flexible in cylinder body, coordinate, make the piston rod of making fore and aft motion in inner cylinder tube, can in limited length, realize the traveling priority of longer distance, save installing space and meet the usage requirement of some special occasions shift length.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of compact type telescopic oil cylinder as shown in Figure 1, comprise cylinder body 1, with the cylinder bottom 2 of cylinder body 1 integrative-structure, be arranged on the piston rod 3 in cylinder body 1 and be located at the piston 4 of piston rod 3 rearward end.
3, cylinder body 1 and piston rod are provided with inner cylinder tube 5, be provided with the first guide sleeve 7 between cylinder body 1 front inner wall and inner cylinder tube 5, inner cylinder tube 5 front ends and the first guide sleeve 7 are slidably matched, inner cylinder tube 5 rear ends and cylinder body 1 inwall cooperation place are provided with the first guide ring 6, and inner cylinder tube 5 rear ends and cylinder body 1 inwall are slidably matched.Be provided with the second guide sleeve 9 between inner cylinder tube 5 front ends and piston rod 3, piston rod 3 front ends and the second guide sleeve 9 inwalls are slidably matched.Piston 4 is provided with the second guide ring 8 with inner cylinder tube 5 inwall cooperation places, and piston 4 is slidably matched with inner cylinder tube 5 rear ends.Hydraulic oil can flow by oil duct 13 in rod chamber and rodless cavity, and under the pressure-acting of hydraulic oil, the second guide ring 8 and the second guide sleeve 9 guiding piston rods 3 are done flexible reciprocatingly sliding in inner cylinder tube 5.
In order to reduce the impact of piston rod 3 when the to-and-fro motion, piston rod 3 is provided with cushion collar 10 with piston 4 joints, in order to improve better cushioning effect, be provided with buffer ring 12 in the second guide sleeve 9, further, in the first guide sleeve 7, be provided with dust ring 11, improved the sealing and dustproof performance.
Because inner cylinder tube 5, piston rod 3 are equipped with, in the finite length of cylinder body 1 inside, inner cylinder tube 5 can coordinate with piston rod 3 straight line motion of doing double cylinder body 1 length, not only compact structure, save installing space, and meet the usage requirement of shift length at some special occasions.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
