Description
Technical field
The present invention relates to a kind of door closer, a kind of have the door closer sealing structure.
Background technology
The basic role of door closer is to be automatically switched off by door, moreover it is possible to steadily close with protection doorframe and door body.The basic building block of door closer has and has the housing of cavity, tooth bar plunger, travelling gear.The gear shaft of travelling gear is located in the cavity of housing rotationally, and gear driven tooth bar plunger moves in the horizontal direction, is full of hydraulic oil in the cavity of housing.In prior art, gear shaft two ends are located in two limit lids the most rotationally, and limit lid is connected with housing, prevent hydraulic oil seepage by arranging sealing ring between limit lid and gear shaft.But sealing ring is point cantact with gear shaft and contacting of limit lid, and contact area is little, and sealing effectiveness is poor.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of door closer having and sealing structure, it has preferable sealing effectiveness.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of have the door closer sealing structure, including the housing with inner chamber, the piston body being arranged in described inner chamber and can move in the horizontal direction, arrange on the housing and have two limit lids of through hole, it is located in the gear shaft in the through hole of said two limit lid rotationally and is arranged on the sealing ring between described gear shaft and described limit lid, described interior intracavity is full of hydraulic oil, described through hole connects with described inner chamber, the gear being meshed with described piston body it is provided with on described gear shaft, described gear shaft offers the groove of mating shapes with described sealing ring along its circumferencial direction, described sealing ring is arranged between described groove and limit lid.
Preferably, body that described limit lid includes having through hole, the circle flange formed along the circumferencial direction of described body, described flange is fixedly installed on the body and towards described inner chamber, described body is formed with the corner part contacted with described sealing ring, the shape of described corner part inwall and the mating shapes of described sealing ring with the junction of described flange.
Preferably, the cross section of described sealing ring is circular.
It is highly preferred that the shape of the inwall of described corner part is substantially in circular arc.
Preferably, described groove is circular arc along the cross section of the axis direction of described gear shaft.
The present invention uses above structure, has the advantage that the part by being contacted by door closer with sealing ring, i.e. gear shaft, the inwall of limit lid corner part is shaped to the shape matched with it, increases the contact area with sealing ring；Compared to sealing ring in prior art and gear shaft, the point cantact of limit lid, by offering the groove accommodating sealing ring in gear shaft, sealing ring serving a position-limiting action, its sealing effectiveness is more stable.
