Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
The single-point locking handle for the casement window is shown in fig. 1-9 and comprises a handle 1, a pressing block gasket 2, a base 3, a positioning piece 4 and a positioning gear 5; the pressing block gasket is formed by integrating the pressing block and the gasket, so that the number of parts is reduced. The pressing block gasket is embedded and extruded in the groove 6 of the handle, so that the connection between the two parts is more reliable. The briquetting packing ring is connected the base, the base facial make-up is equipped with the setting element, and the positioning gear afterbody has square pole 18, and positioning gear wears to establish in proper order square groove 19 cooperation of inslot on the square pole of its afterbody and the handle behind setting element, base, the briquetting packing ring still is equipped with screw hole 20 in square groove bottom, and the screw (not shown in the figure) passes positioning gear's fixed orifices 25 again and connects in the whole handle of further fixed equipment in the screw hole.
The base is provided with the sector grooves 7, the limiting blocks 8 on the handle penetrate through the press block gasket and are matched with the sector grooves and rotate in the range of the sector grooves, and the structure can prevent the handle from rotating excessively, namely the handle is limited to rotate back and forth in the range of 90 degrees. Certainly, the briquetting washer is provided with a first through hole 21 and a second through hole 22, a partition plate 23 is arranged between the first through hole and the second through hole, the partition plate is used for preventing one end of the handle from tilting due to the fact that no stress point exists at the position, and the first through hole and the second through hole are used for allowing the limiting block to penetrate through and are used for matching with opening doors and windows at different positions.
The positioning member of this embodiment includes a frame body 8, wherein elastic pieces 9 are disposed on both sides of the frame body, and the elastic pieces have protruding teeth 10. The elastic sheet is an arc-shaped plastic body. Two ends 11, 12 of the elastic sheet are respectively erected at two corners 13, 14 of the frame body. The elastic piece comprises a first elastic piece and a second elastic piece, and the first elastic piece and the second elastic piece are arranged in the frame body oppositely. The positioning gear is provided with an outer circular body 15, the outer circular body is positioned in the frame body cavity 16, a plurality of concave teeth 17 are uniformly distributed on the side wall of the outer circular body, and when the positioning gear rotates in the frame body cavity, the convex teeth are meshed with the concave teeth. The concave teeth comprise a first concave tooth, a second concave tooth, a third concave tooth and a fourth concave tooth.
