Abstract
The utility model discloses an improved oil bag which comprises an oil bag body. The body comprises an inner wall, an outer wall and a bag seat, a clearance is arranged between the inner wall and the outer wall, an inner reinforcement plate with the shape consistent with that of the clearance is arranged in the clearance, the bag seat is arranged at the upper end of the inner wall and the upper end of the outer wall, an outer reinforcement plate matched with the outer wall is arranged on the outer side of the outer wall, and a fixed end face parallel to the lower end face of the bag seat is arranged at the upper end of the outer reinforcement plate. The improved oil bag is simple in structure, the telescopic variable quantity of the oil bag is limited through an inner wall and outer wall dual-layer mechanism of the oil bag, the inner reinforcement plate and the outer reinforcement plate, the oil bag is effectively prevented from being stretched out or drawn back or broken, the oil bag is prevented from being broken, the service life of the oil bag is prolonged, and high practicality is achieved.
Description
Technical field
The utility model relates to oil sac, is specifically related to a kind of modified model oil sac of using for pump.
Background technique
Pump is taking up lubricant oil with oil sac, when providing lubricating function for the motion of pump, also for the inner chamber of canned pump, make the pressure balance between interior exocoel, in the time that inner chamber is pressed increase, oil sac wall inwardly compresses, top is pushed downwards, and oil chamber volume increases, and has reduced interior pressure.In the time that external pressure increases, oil sac wall stretches to surrounding, and top is upwards pushed, and oil chamber volume diminishes, and has reduced external pressure, ensures chamber pressure balance.But because the flexible ability of oil sac is very limited, after the large or flexible certain number of times of the flexible intensity of oil sac, just can cause oil sac to break, impurity enters in pump with water, and then causes pump to damage.Therefore seem particularly important the flexible working life of breaking, improving oil sac that solves oil sac.
Model utility content
For above-mentioned deficiency, the purpose of this utility model is to provide a kind of modified model oil sac, by the double-deck mechanism of inside and outside wall of oil sac, and by inside and outside stiffening plate is set, limit oil sac telescopic variation amount, effectively prevent that the flexible of oil sac from breaking, extend the working life of oil sac.
In order to address the above problem, the technical solution of the utility model is:
The utility model provides a kind of modified model oil sac, comprise oil sac body, described body comprises inwall, outer wall and capsule seat, between described inner and outer wall, space is set, in space, be provided with the interior stiffening plate consistent with void shape, described capsule seat is positioned at inner and outer wall upper end, and described outer exterior wall is provided with its external reinforcing plate for car matching, and described external reinforcing plate for car upper end is provided with the fixing end face parallel with capsule seat lower end surface.
Further improvement of the utility model is: the bottom of described inwall, outer wall is provided with depression, is arc transition between the sidewall of described depression and inwall, outer wall.
Further improvement of the utility model is: on described capsule seat and fixing end face, offer fixed hole.
Further improvement of the utility model is: described interior stiffening plate and external reinforcing plate for car are sheet metal, and the both ends of the surface of sheet metal are provided with corrosion-inhibiting coating.
Further improvement of the utility model is: on the exterior edge face of described inwall, the interior edge face of outer wall and exterior edge face, be all evenly provided with stiffening rib; Described stiffening rib comprises the outer reinforcement of the annular parallel with capsule seat, and the perpendicular outer reinforcement being interspersed with the outer reinforcement of annular.
The utility model has the advantage of: by the double-deck mechanism of inside and outside wall of oil sac, and by inside and outside stiffening plate is set, limit oil sac telescopic variation amount, effectively prevent that the flexible of oil sac from breaking, prevent from causing oil sac to break, extend the working life of oil sac.By depression is set, strengthen the anti-pressure ability of oil sac bottom, thereby improve the working life of oil sac, the arc transition of depression and sidewall, the conformity of effective guarantee outer wall and inwall integral telescopic distance, prevents that the part of oil sac is excessively flexible and damaged; By stiffening rib is set, not only can strengthen inside and outside wall, improve the flexible ability of oil sac, and the support of effective guarantee stiffening plate to inside and outside wall, the distance of stretch out and draw back of effective guarantee inside and outside wall, effectively prevents the breakage causing because of flexible transition of oil sac wall, improves oil sac working life.By setting corrosion-inhibiting coating, ensure the anticorrosive property of stiffening plate, prevent that sheet metal is corroded, ensure the long-lasting of sheet metal supporting effect; By offer fixed hole on capsule seat, be conducive to the fixed installation of oil sac.
The utility model is simple in structure, effectively prevent that the oil sac that is excessively flexible and that cause of oil sac from breaking, and extends the working life of oil sac, and practicability is stronger.
