Description

Sliding rail closer of flat-open sliding door Technical Field The utility model relates to the technical field of doors and windows, in particular to a sliding rail closer of a flat-open sliding door. Background PD door, also called PT door, refers to the door that can push and pull and flat-open, and the product design theory originated at the earliest in Singapore, and is very popular in China for several years. The PT door completely overturns the defect that the traditional sliding door can only be opened half, is mainly used for kitchens, living rooms, balconies and store gates, has the advantages of convenience in opening, large utilization space, attractive appearance, durability and the like, and is deeply favored by consumers. The sliding track of the PT door comprises two parts, wherein one part is a fixed track fixed on the upper part of the door frame, the other part is a movable track fixed on the top of the vertical hinged door leaf, a closer capable of being connected with each other is arranged at the end part between the movable track and the fixed track, the sliding door leaf can slide in a pushing and pulling manner between the fixed track and the movable track, and when the PT door needs to be fully opened, the sliding door leaf needs to slide to the movable track by means of the fixed track and the closer and then rotates outwards to be opened after being overlapped with the vertical hinged door leaf. In the prior art, the inside of fixed part and the movable part of the closer are provided with pulley cavity structures which are the same as the inside of the fixed track and the movable track, and are used for enabling pulleys at the top of the sliding door leaf to slide when the fixed part and the movable part are mutually in butt joint. The connecting end face between the fixed part and the moving part of the closer is spliced by the inclined surface, a certain gap is needed to enable the vertical hinged door leaf to be operated in a flat mode, so that the pulley at the top of the sliding door leaf can shake when passing through the gap, smooth sliding feeling of the sliding door leaf is affected, and use experience is reduced. Disclosure of utility model The utility model aims to provide a sliding rail closer of a sliding door, which aims to solve the problem that a pulley at the top of a sliding door leaf can shake when passing through a gap due to the fact that a gap exists after a fixed part and a moving part of the closer are in butt joint in the prior art. In order to achieve the aim, the utility model provides a sliding rail closer of a sliding door, which comprises a moving part and a fixing part which are matched with each other, wherein pulley installation cavities which can be communicated with each other during matching are formed in the moving part and the fixing part, pulley tracks are arranged at the bottoms of the pulley installation cavities, a first extension part is arranged at the end part of each pulley track on the moving part, a second extension part is arranged at the end part of each pulley track on the fixing part, and splicing tracks are formed by the first extension part and the second extension part during matching and are communicated with the pulley tracks. Further, the end surfaces of the pulley rails on the moving part and the fixed part, which are matched relatively, are inclined surfaces inclined in the same direction, and the end surfaces of the first extending part and the second extending part are inclined surfaces inclined in the same direction.
