Detailed Description

The invention will be further described in the following with reference to the accompanying drawings in which specific embodiments are shown.

As shown in fig. 1-5, a door and window lock body comprises a shell, wherein the shell is composed of a base 1 and a cover plate 2, a side plate 3 is further connected to one side of the shell, and the side plate 3 and the base 1 can be integrally formed or connected to the base 1 or the cover plate 2.

A pull plate groove 31 is arranged on the side plate 3, the outer end of the side plate 3 is connected with a main pull plate 4 and an auxiliary pull plate 5, the main pull plate 4 and the auxiliary pull plate 5 can move relative to the side plate 3, the main pull plate 4 and the auxiliary pull plate 5 are both provided with an extending end 41, the extending end 41 penetrates through the pull plate groove 31 and extends into the shell, a rotary hole 12 is arranged on the base 1, a linkage disk 7 is connected in the rotary hole 12, two side wings 71 of the linkage disk 7 are provided with first convex columns 72, the extending ends 41 of the main pull plate 4 and the auxiliary pull plate 5 which are opposite are both provided with first poking grooves 42, the first poking grooves 42 on the main pull plate 4 and the auxiliary pull plate 5 are respectively connected with the first convex columns 72 on the side wings 71 on the linkage disk 7, when the linkage disk 7 rotates, the main pull plate 4 and the auxiliary pull plate 5 are close to or far away from each other, a core hole 11 is also arranged on the base 1, a poking button 6 is connected in the square core hole 11, and a swing arm 61 is formed on the, be formed with second projection 62 on the swing arm 61, be formed with the second on the end 41 that stretches into of main arm-tie 4 in addition and dial groove 43, dial second projection 62 on the 6 swing arms 61 of button and stretch into main arm-tie 4 and stretch into in the second of end 41 dials groove 42, it links to each other with external handle to dial button 6, when will dial button 6 through the handle and rotate, dial second projection 62 on the 6 swing arms 61 of button and dial groove 43 through the second and drive main arm-tie 4 and move, because main arm-tie 4 and vice arm-tie 5 all link to each other with link plate 7, consequently, when main arm-tie 4 moves, it drives vice arm-tie 5 through link plate 7 and moves, realize when rotating and dial button 6, main arm-tie 4 and vice arm-tie 5 are close to each other or keep away from each other. Since the main pulling plate 4 and the auxiliary pulling plate 5 are connected with the components on the door and window, the door and window can be closed or opened by the action that the main pulling plate 4 and the auxiliary pulling plate 5 approach or move away from each other.

Further, the opening part of the second toggle groove 43 is formed with an anti-lock inclined plane 44, when the second convex column 62 on the swing arm 61 of the toggle 6 rotates to make the main pulling plate 4 and the auxiliary pulling plate 5 far away from each other, namely when the door and window is closed, the second convex column 62 can support the anti-lock inclined plane 44, so that under the condition that the toggle 6 does not rotate, the movement possibility of the main pulling plate 4 is limited, the mutual approach between the main pulling plate 4 and the auxiliary pulling plate 5 caused by external force or other factors is avoided, and the door and window is opened accidentally.

Further, be connected with backplate 8 in the outer end of curb plate 3, backplate 8 compresses tightly main arm-tie 4 and vice arm-tie 5 on curb plate 3, prescribes main arm-tie 4 and vice arm-tie 5 between backplate 8 and curb plate 3, can not take place to rock.

Further, in order to realize the stability of the relative movement of the main pulling plate 4 and the auxiliary pulling plate 5, sliding grooves 45 are respectively arranged on the main pulling plate 4 and the auxiliary pulling plate 5, and the moving path of the sliding grooves 45 is limited by sliding columns 81 on the side plates 3.

Further, traveller 81 runs through backplate 8 and curb plate 3 to its one side is equipped with screw cap 82, and the opposite side is connected with retaining member 83, through install this door and window lock body to door and window back, screws retaining member 83 through screw cap 82 again, makes retaining member 83 card in the position that meets with the door and window, makes the lock body inseparabler with being connected of door and window, and is firm.

As shown in fig. 4 and 5, the base 1 is provided with two limiting posts 13, two limiting ports 46 are formed on the extending ends 41 of the opposite main pulling plates 4, the number of the limiting posts 13 is two, the two limiting posts are respectively located at two ends of the base 1, the number of the limiting ports 46 is also two, the two limiting ports are respectively located at two sides of the extending ends 41 of the main pulling plates 4, the movement stroke of the main pulling plate 4 can be limited by the limiting posts 13 through the limiting ports 46 on the extending ends 41 of the main pulling plates 4, when the rotation of the dial button 6 is avoided, the main pulling plate 4 moves beyond the set stroke, the main pulling plate 4 and the auxiliary pulling plate 5 are too close to each other and too far away from each other, and the design requirements are not met.

Further, be equipped with reference column 14 on base 1, reference column 14 is connected with support frame 9, and the both sides of support frame 9 offset with base 1 and apron 2 respectively, strengthen the structure of whole lock body to it will dial including button 6 cladding, make the rotation of dialling button 6 more steady, and not only rely on square core hole 11 to its restriction.

As shown in fig. 4 and 5, the base 1 is provided with the connection post 15, the connection post 15 is provided with the through connection hole 151, in the conventional door and window lock body, the connection hole 151 of the connection post 15 is non-through type, generally, when the lock body is installed, a person is located at an indoor side, so that the connection hole 151 needs to be installed toward the person side, the connection hole 151 is through type by improving the connection hole 151, and the connection hole 151 is made to face the indoor side no matter whether the installation orientation of the lock body is correct, thereby facilitating the installation of the lock body.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited according to this, any person should learn the structural change made under the teaching of the present invention, all with the present invention has the same or similar technical solution, all fall into the protection scope of the present invention.
