Description

Self-locking window closer

Technical Field

The utility model relates to a window accessory field, especially a self-locking window closer.

Background

In the existing sash window structure, the window body is fixed through the connecting rods respectively connected with the window frame and the window body, namely after the window body is opened by opening a sash, the bolt on the connecting rod is screwed, the tail end of the bolt supports against the connecting rod, and the window body is fixed through static friction between the bolt and the connecting rod.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a self-locking window closer, includes guide pin bushing 1, rack 2 has been inlayed in the guide pin bushing 1, the connecting seat 3 of being connected with window frame, window respectively is all installed to the end of guide pin bushing 1, rack 2, install axle bed 6 on the guide pin bushing 1, install pivot 4 in the axle bed 6, the terminal embedding of pivot 4 in the guide pin bushing 1 and with the meshing of rack 2.

The head end of the rack 2 is embedded into the guide sleeve 1, the head end of the rack 2 is provided with a piston block 12, the piston block 12 is matched with the inside of the guide sleeve 1, and the piston block 12 provides limiting guide for the sliding connection of the guide sleeve 1 and the rack 2.

The head end of the shaft pin 4 is provided with a handle 5, and the handle 5 and the shaft pin 4 are of an integral structure formed by one-time casting.

The side wall of the shaft pin 4 is provided with a clamping bolt 7, the clamping bolt 7 is embedded into the shaft seat 6, and the clamping bolt 7 and the shaft pin 4 are of an integral structure formed by one-step casting.

A spring 8 is arranged between the shaft pin 4 and the shaft seat 6, and the spring 8 is positioned in the shaft seat 6.

The shaft seat 6 is provided with a groove, the groove comprises a first groove 10 and a second groove 11, the diameter depth of the first groove 10 is smaller than that of the second groove 11, the clamping bolt 7 is embedded into the groove, when the clamping bolt 7 is embedded into the first groove 10, the tail end of the shaft pin 4 is separated from the rack 2, and when the clamping bolt 7 is embedded into the second groove 11, the shaft pin 4 is embedded into sawteeth on the rack 2.
