Abstract
The utility model provides a guide sleeve capable of substituting threaded connection, comprising a guide sleeve and a cylinder barrel, wherein the guide sleeve is arranged in the cylinder barrel, a piston rod extends out through the guide sleeve, an O-shaped ring is arranged between the guide sleeve and the cylinder barrel, a key slot is arranged in the inner wall on the end part of the cylinder barrel, and a footstep is arranged on the excircle on the end part of the guide sleeve and is matched with the key slot; the outer end face of the guide sleeve is also provided with a retainer ring which is fixed on the outer end face of the guide sleeve; and a clip key is further arranged in the key slot arranged between the retainer ring and the footstep. By using the guide sleeve, the O-shaped ring can be effectively prevented from being damaged, the working efficiency for assembly is increased, the sealing property of an engineering hydraulic cylinder is greatly enhanced, and the labor intensity of an operator is greatly reduced.
Description
Technical field
The utility model relates to a kind of guide sleeve in the hydraulic jack, specifically is a kind of alternative guide sleeve that is threaded.
Background technique
The Engineering hydraulic jack utilizes the guide sleeve that is threaded in using production process, brought very big difficulty for manufacturing work, especially the sealability of guide sleeve is threaded, be difficult to reach the requirement of high pressure, and guide sleeve cylindrical " O " type circle because it twists stressed easy damage, causes leakage of oil in assembling and using process.
Summary of the invention
The utility model provides a kind of alternative guide sleeve that is threaded, and can effectively reach sealing effect, and can promote the use of the engineering hydraulic jack.
In order to address the above problem, the technical solution of the utility model is as follows, a kind of alternative guide sleeve that is threaded comprises guide sleeve, cylinder barrel, be provided with guide sleeve in the cylinder barrel, piston rod stretches out by guide sleeve, is provided with " O " type circle between guide sleeve and the cylinder barrel, it is characterized in that: be provided with keyway on the inwall of cylinder barrel end, be provided with step on the cylindrical of guide sleeve end, step and this keyway cooperate; Be provided with baffle ring on the guide sleeve exterior edge face again, baffle ring is fixed on the guide sleeve exterior edge face; Be provided with the card key in the keyway between baffle ring and the step again.
Beneficial effect:
Use card key formula guide sleeve described in the utility model, utilize the preceding card key of baffle ring to fix, make spinning and the distortion of guide sleeve, can effectively prevent the damage of " O " type circle without screw thread, improve assembling work efficient, strengthened the sealability of Engineering hydraulic jack greatly.Use the cooperation of card and baffle ring, help through the location work that compresses, alleviated significantly the operator labor intensity, improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Card key 1, baffle ring 2, guide sleeve 3, piston rod 4, cylinder barrel 5. " O " type circle 6, " O " type circle 7, keyway 8.
Embodiment
A kind of alternative guide sleeve that is threaded of the utility model as shown in Figure 1.
Comprise guide sleeve 3, cylinder barrel 5 is provided with " O " type circle 6,7 between guide sleeve 3 and the cylinder barrel 5, be provided with keyway 8 on the inwall of cylinder barrel 5 ends, is provided with step on the cylindrical of guide sleeve 3 ends, and step and keyway 8 cooperate; Guide sleeve is provided with baffle ring 2 on 3 exterior edge faces again, and baffle ring 2 is fixed on guide sleeve 3 exterior edge faces; Be provided with card key 1 again in the keyway 8 between baffle ring 2 and the step.
During assembling, earlier guide sleeve 3 is sleeved on the piston rod 4, guide sleeve 3 is to pressing down then, up to the position of size well below circlip groove 8, to block key 1 and load onto, then guide sleeve 3 be risen to the position of card key 1, will block key 1 usefulness baffle ring 2 at last and be fixed on the guide sleeve 3 by set screw with aerodynamic force.
