Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
The corner connector component with the anti-theft and anti-prying functions for the door and window sash is shown in fig. 1-11 and comprises a corner connector shell 2 installed on a push window 1, an elongated connecting brace 4 sliding back and forth on a rail 3 on the corner connector shell, and a stop block 5 is arranged at the bottom of the elongated connecting brace. A lower rail 6 of the corner device shell is also provided with a guide sheet 7 made of a stainless steel sheet, one end of the guide sheet is connected with a slide block 8 sliding on the lower rail, and the slide block is connected with a hinged piece (in the prior art, the description is not repeated); the other end is connected with the lengthened connecting brace in a riveting mode, a corner cover 9 covering the lower rail is arranged at the corner of the corner device shell, and a guide channel 10 for the guide piece to penetrate is formed by the corner cover and the corner device shell together. The power of the back-and-forth movement of the lengthened connecting brace comes from a handle (in the prior art, the description is not repeated), and a mushroom head sliding anti-theft lock point 11 is arranged on the lengthened connecting brace.
Further, the anti-theft and anti-prying lock device further comprises an anti-theft and anti-prying lock catch 13 mounted on the window frame 12, wherein a first lock hole 14 is formed in one side of the anti-theft and anti-prying lock catch, the size of the first lock hole is just matched with the sliding anti-theft lock point of the mushroom head, the first lock hole comprises a first deep opening 15, a communicated first opening 16 is formed in the upper portion of the first deep opening, and first shoulder portions 17 and 18 are formed in two sides of the first opening; the anti-theft and anti-prying lock catch is H-shaped, a second lock hole 19 is formed in the other side of the anti-theft and anti-prying lock catch, the second lock hole comprises a second deep opening 20, a communicated second opening 21 is formed in the upper portion of the second deep opening, and second shoulders 22 and 23 are formed in two sides of the second opening. The corner device shell is further provided with an error prevention device switch 24, the error prevention device switch comprises a fixed block 25, an elastic piece (the elastic piece is a torsion spring 26) and a reset deflector rod 27, the side edge of the reset deflector rod is arranged opposite to the top block 28 of the window frame, and the front face of a blocking block 31 of the reset deflector rod is arranged opposite to the stop block 5. When the sliding window is closed to the window frame, the ejector block on the window frame can apply a pushing force to the reset driving lever, the reset driving lever is pushed away until the stop block of the reset driving lever is not opposite to the stop block, then the handle is screwed, the handle drives the lengthened connecting brace to move, the mushroom head sliding anti-theft lock point on the lengthened connecting brace can slide into the first lock hole on the anti-theft anti-prying lock catch, and therefore the sliding window is locked on the window frame.
