The utility model content

The purpose of this utility model is the mortise bolt that provides firm, safe.

The purpose of this utility model is achieved in that mortise bolt, comprise support, panel, shift fork, shift fork connector, spring, guide pin, tapered end connector, tapered end attaching nut, latch screw rod, fixed axis, rivet, described support is welded on the panel, described shift fork is connected by the shift fork connector with guide pin, be lined with spring on the described shift fork connector, the described spring other end is resisted against in the circular cambered surface of described tapered end connector, described tapered end attaching nut and the welding of described tapered end connector, the two ends of described shift fork connector pad spring section are provided with projection.

In order to make above-mentioned mortise bolt be convenient to installation and more firm, preferably by the punching press riveted joint, riveted holes adopts the mode of big aperture to be provided with, with having or not the R breach to distinguish macropore and aperture for above-mentioned shift fork connector and guide pin.

In order further to improve the fastness and the safety of above-mentioned mortise bolt, above-mentioned panel all preferably takes butt welding to be connected with support, tapered end attaching nut with the tapered end connector.

Above-mentioned support, panel and shift fork all adopt the stainless steel material punch forming, and above-mentioned rivet adopts solid rivet.

Above-mentioned panel is provided with panel hole, is more convenient for operating in order to make above-mentioned mortise bolt, and described panel hole is the orthodrome panel hole.

Above-mentioned shift fork, the operation part that its front end is used to stir is the R shift fork through the R chamfered.

When the user pulled shift fork, shift fork produced deflection around fixed axis and enters fully on the tapered end connector circular arc R face up to the shift fork connector, and stirred the tapered end connector and slidably reciprocate.

The utility model mortise bolt can be with on various doors or the window.

The utility model mortise bolt, the circular arc drawing process is taked at the two ends of shift fork connector pad spring section, its two ends are increased, make the circular arc pull and stretch increase part and form little matched in clearance with tapered end connector cambered surface, played the pad spring and be connected the effect of shift fork with leading, and make tapered end connector and main body longitudinal leap reduce to for 5.5～7 millimeters from original play to have only 1.2～1.5 millimeters play, make door or window is more smooth successfully locks, improved the safety of door or window; The utility model mortise bolt accessory all adopts stamping forming mode, compares with the mortise bolt accessory of present employing aluminium alloy compression casting and copper die casting, has reduced cost of production, the utility model mortise bolt is easy for installation, and the intensity height is wear-resistant, long service life, handled easily, safe and reliable.
