Abstract

A locating structure of an oil pressure door closer is composed of a locating plate, a main body of the door closer, and a plurality of fastening pins. The locating plate is fastened with a door and provided with a plurality of fastening holes. The main body is provided in one longitudinal side thereof with two longitudinal edges parallel to each other and forming therebetween a longitudinal space for accommodating the locating plate. The two longitudinal edges are provided with a plurality of through holes corresponding in location to the fastening holes of the locating plate. The fastening pins are received in the through holes and the fastening holes for fastening the main body with the locating plate.

Claims

1. A locating structure of an oil pressure door closer, said locating structure comprising:

a locating plate adapted to be fastened with a door and provided with a plurality of fastening holes parallel to surface of the door;

a main body of a door closer and provided in one longitudinal side thereof with two longitudinal edges parallel to each other and forming therebetween a longitudinal space for accommodating said locating plate, said two longitudinal edges provided with a plurality of through holes corresponding in location to said fastening holes of said locating plate; and

a plurality of fastening pins received in said through holes and said fastening holes for fastening said main body with said locating plate.

2. The locating structure as defined in claim 1, wherein said fastening pins have a shank and a head greater in diameter than said shank.

3. The locating structure as defined in claim 2, wherein said shank is equal in length to the sum of a width of said locating plate and the thickness of said two longitudinal edges.

4. The locating structure as defined in claim 2, wherein said shank is smaller in length than the sum of a width of said locating plate and the thickness of said two longitudinal edges.
