Retractable anti-theft door and window and sliding sheet assembly thereof

Abstract

The invention relates to a retractable anti-theft door and window and a sliding sheet assembly of the retractable anti-theft door and window. The sliding sheet assembly comprises a sliding sheet body, an elastic clamp and a hinged shaft used for hinging the sliding sheet body to one connecting piece of the retractable anti-theft door and window. An hinged hole is formed in the end of the sliding sheet body, the elastic clamp is installed on the sliding sheet body and intersects with the hinged hole, an axial limiting clamping groove is formed in the hinged shaft, the hinged shaft penetrates through the hinged hole, and the axial limiting clamping groove is connected with the elastic clamp in a clamping mode. The retractable anti-theft door and window comprises a frame, multiple grid tubes and multiple connecting pieces, sliding rails are installed in the frame, the grid tubes are arranged on the sliding rails in a sliding mode, every two adjacent grid tubes are connected through two connecting pieces hinged mutually, the sliding sheet assembly of the retractable anti-theft door and window is arranged in each grid tube in a sliding mode, a sliding groove is formed in each grid tube and corresponds to one sliding sheet assembly, and the hinged shaft in each sliding sheet assembly penetrates through the corresponding sliding groove to hinge one connecting piece to the corresponding sliding sheet body. The retractable anti-theft door and window and the sliding sheet assembly of the retractable anti-theft door and window have the advantages of being simple in structure, convenient to install and high in generality.

Description

technical field [0001] The invention relates to an anti-theft door and window, in particular to a slide assembly of a telescopic anti-theft door and window and a telescopic anti-theft door and window. Background technique [0002] At present, anti-theft doors and windows are basically divided into two types, one is a completely closed fixed type, and the other is an openable telescopic type. Telescopic protective doors and windows have the advantages of convenient and flexible use, simple and firm structure, and exquisite and beautiful appearance, so they are more and more favored by people. [0003] The existing telescopic anti-theft doors and windows are generally composed of a frame, a plurality of grid pipes and a plurality of connecting pieces. Slide rails are installed in the frame, and the ends of the grid pipes are slid on the slide rails. The grid pipes are connected by connecting pieces, and the push-pull grid When installing the grid tube, one end of the connecti...

Problems solved by technology

[0003] The existing telescopic anti-theft doors and windows are generally composed of a frame, a plurality of grid pipes and a plurality of connecting pieces. Slide rails are installed in the frame, and the ends of the grid pipes are slid on the slide rails. The grid pipes are connected by connecting pieces, and the push-pull grid When installing the grid tube, one end of the connecting piece rotates relative to the grid tube, and the other end slides relative to the grid tube. This kind of protective door and window has the following problems: 1. The structure of the end of the connecting piece that slides relative to the grid tube is very complicated, and it is difficult to install. In case of jamming or connection failure; 2. The grid tube only falls on the slide rail through the pulley, and the constraint between the track and the track is too simple, which is prone to derailment; 3. The slide rail and the grid tube are arranged in a single row. After the grid tube is folded to one side, it will still occupy a large space; 4. When the existing slide rails and grid tubes are arranged in double rows, a metal collar riveted connecting piece is installed outside a row of grid tubes to slide, and the telescopic grid tube It is easy to make friction sound and wear the surface coating of the grid tube. What's more, the metal collar is set outside the grid tube, which is easy to be damaged and loses the anti-theft effect
