Abstract
The utility model discloses a novel waterproof structure of a hydraulic cylinder guide sleeve. The novel waterproof structure comprises the guide sleeve, a first O-shaped ring, a second O-shaped ring, a blocking ring and a cylinder barrel. The first O-shaped ring, the second O-shaped ring, the blocking ring and the cylinder barrel are arranged on the outer circle of the guide sleeve, the guide sleeve and a cylinder body are sealed through the O-shaped rings and the blocking ring, and a waterproof O-shaped ring is additionally arranged on the outermost end to seal the guide sleeve and the cylinder body. Due to additional arrangement of the waterproof O-shaped ring, the guide sleeve is prevented from rusting, and meanwhile dust removal effect between the guide sleeve and the cylinder body is strengthened, and cleanliness of an oil cylinder is better guaranteed.
Description
Technical field
The utility model belongs to the hydraulic element field, particularly the oil hydraulic cylinder used of a kind of engineering machinery.
Background technique
At present, the action of equipment in the engineering machinery adopts the reciprocating double-action oil hydraulic cylinder that hydraulic pressure can be transformed into mechanical energy mostly, the turning to, overturn, excavate, hoist etc. of control equipment.At present, have a kind of oil hydraulic cylinder to adopt the thread type guide sleeve to be connected with cylinder barrel, its advantage is to save the space, and is in light weight, but exists screw thread easily to get rusty, the problem of difficulty during repair demolition.
Summary of the invention
The purpose of this utility model provides a kind of oil hydraulic cylinder guide sleeve new waterproof structure with regard to being at the defective of above-mentioned prior art.
Its technical solution is as follows:
A kind of oil hydraulic cylinder guide sleeve waterproof construction, it comprises guide sleeve, waterproof O type circle, cylinder barrel, O type circle, back-up ring.
The utility model seals between guide sleeve and cylinder body except O type circle, back-up ring, has increased waterproof O type circle one in outermost end.Owing to after having increased this road waterproof O type circle, both avoided guide sleeve to get rusty, strengthened the dustproof effect between guide sleeve and the cylinder body simultaneously, better guarantee the turbidity test of oil cylinder.Solved the guide sleeve screw thread and easily got rusty, the problem of difficulty during repair demolition.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of a kind of mode of execution of the utility model.
Embodiment
As shown in the figure, the utility model mainly comprises thread type guide sleeve 6, O shape circle 3, back-up ring 4, the capable circle 5 of O, cylinder barrel 13.O shape circle 3, back-up ring 4, O shape circle 5 are contained in respectively between guide sleeve 6 and the cylinder barrel 13, play a part to stop dust and moisture to enter, and particularly O shape circle 3 guarantees the not corrosion of guide sleeve screw thread more, have solved the problem of dismounting difficulty.
Claims (1)
1. an oil hydraulic cylinder guide sleeve waterproof construction is characterized in that comprising guide sleeve, waterproof O type circle, cylinder barrel, O type circle, back-up ring, it is characterized in that: sealing has increased waterproof O type circle one in outermost end between described guide sleeve and the cylinder body except O type circle, back-up ring.
