Abstract
The utility model belongs to the technical field of the oil cylinder technique and specifically relates to that relate to is an oil cylinder, including cylinder body, cylinder cap, piston, piston rod and brake valve lever. Piston rod upper portion is the bulb, and the brake valve lever lower part is equipped with the ball groove of matcing with the bulb, the ball inslot is equipped with the annular, has placed the supporting ring in the annular. The wearability between annular and multiplicable brake valve lever of supporting ring and the bulb is established to the ball inslot, and then improves oil cylinder's life. And cylinder body upper portion diameter is greater than the lower part diameter, and the middle part is obconical, and the oil cylinder who straightens the cylinder has bigger intensity, and life is longer.
Description
Technical field
The utility model relates to oil cylinder technical field, and what especially relate to is a kind of oil cylinder.
Background technique
On the market, have the oil cylinder of bulb piston rod, the ball groove on bulb and the link that is connected with bulb is all light face, and the time long occlusion that gets rusty easily, affects bulb piston rod and link, and then the working life of oil cylinder is reduced greatly.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of oil cylinder with bulb piston rod of long service life.
For achieving the above object, technical solution of the present utility model is: a kind of oil cylinder, comprises gray iron, piston, the piston rod be connected with piston and is connected to the Joystick of piston rod upper end.Piston rod top is bulb, and Joystick bottom is provided with the ball groove mated with bulb; Be provided with annular groove in ball groove, in annular groove, be placed with supporting ring.Joystick comprises two ends by bolted upper handle and retaining ring, and upper handle is positioned at the bulb first half, and bulb and Joystick, in bulb bottom, are connected and fixed by Fixing shrink ring.Establish annular groove and supporting ring can increase wear resistance between Joystick and bulb in ball groove, prevent both from getting rusty occlusion and then the working life of raising oil cylinder.
Preferably, described cylinder body comprise be connected with cylinder cap top, bottom and connection top and bottom middle part; The diameter on top is greater than base diameter, and middle part is inverted cone shape; Middle part lower end diameter is equal with bottom, and is less than middle part upper end diameter.The thickness increased in the middle part of cylinder body can strengthen the intensity of oil cylinder.
Preferably, cylinder body is provided with oil input channel and relief opening; The import of oil input channel is positioned at cylinder body upper outside, and the outlet of oil input channel is positioned at inside inferior part of the cylinder block, fueling operation time easy to use.Relief opening is positioned in the middle part of cylinder body, and level runs through the sidewall of cylinder body, and staggers with oil input channel.
Preferably, O RunddichtringO is provided with between piston and cylinder body.
Preferably, described supporting ring is phenolic aldehyde folder cloth material.Compared with conventional engineering plastics, there is higher thermo-chemical stability and thermo mechanical stability.And there is the comparatively characteristic such as low hardness, impact resistance, self-lubricating abrasion-resistant.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: a kind of oil cylinder, comprise gray iron, piston, piston rod and Joystick.Piston rod top is bulb, and Joystick bottom is provided with the ball groove mated with bulb; Be provided with annular groove in ball groove, in annular groove, be placed with supporting ring.Establish annular groove and supporting ring can increase wear resistance between Joystick and bulb in ball groove, and then improve the working life of oil cylinder.And cylinder body upper diameter is greater than lower diameter, middle part is inverted cone shape, has larger intensity, longer service life compared with the oil cylinder of straight-tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Main Reference Numerals illustrate: (1, cylinder body; 11, top; 12, middle part; 13, bottom; 2, cylinder cap; 3, piston; 4, piston rod; 41, bulb; 5, Joystick; 51, upper handle; 52, retaining ring; 53, annular groove; 6, supporting ring; 7, oil input channel; 71, the import of oil input channel; 72, the outlet of oil input channel; 8, relief opening).
Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of oil cylinder of the utility model, comprises cylinder body 1, cylinder cap 2, piston 3, the piston rod 4 be connected with piston 3 and is connected to the Joystick 5 of piston rod 4 upper end.O RunddichtringO is provided with between piston 3 and cylinder body 1.Piston rod 4 top is bulb 41, and Joystick 5 bottom is provided with the ball groove mated with bulb 4; Be provided with annular groove 53 in ball groove, in annular groove 53, be placed with supporting ring 6.Joystick 5 comprises two ends by bolted upper handle 51 and retaining ring 52, and upper handle 51 is positioned at bulb 41 first half, and retaining ring 52 is placed on bulb 41 bottom, bulb 41 and Joystick 5 is connected and fixed.Establish annular groove 53 and supporting ring 6 can increase wear resistance between Joystick 5 and bulb 41 in ball groove, prevent both from getting rusty occlusion and then the working life of raising oil cylinder.
Described cylinder body 1 comprises the top 11, the bottom 13 that are connected with cylinder cap 2 and connects the middle part 12 of top 12 and bottom 13; The diameter on top 11 is greater than bottom 13 diameters, and middle part 12 is in inverted cone shape; Middle part 12 lower end diameter are equal with bottom 13, and are less than middle part 12 upper end diameter.In the middle part of increase cylinder body 1, the thickness of 12 can strengthen the intensity of oil cylinder.
Cylinder body 1 is provided with oil input channel 7 and relief opening 8; The import 71 of oil input channel 7 is positioned at outside cylinder body top 11, and the outlet 72 of oil input channel is positioned at inside inferior part of the cylinder block 13, fueling operation time easy to use.Relief opening 8 to be positioned in the middle part of cylinder body 12, and level runs through the sidewall of cylinder body 1, and staggers with oil input channel 7.
Described supporting ring 6 is phenolic aldehyde folder cloth material.Compared with conventional engineering plastics, there is higher thermo-chemical stability and thermo mechanical stability.And there is the comparatively characteristic such as low hardness, impact resistance, self-lubricating abrasion-resistant.
Above-described, be only preferred embodiment of the present utility model, the scope that this practicality is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
