Detailed Description

In order to facilitate an understanding of the invention, the invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of the invention is not limited to the specific embodiments below. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 and 2, the key housing comprises a shell 1, a cover plate 2, a sliding rod 3, a spring 4, a key bin 6 and a sliding rod bin 7, wherein the key bin 6 is arranged in the middle of the shell 1, the sliding rod bin 7 is arranged on two sides of the shell, a key handle can be placed in the key bin 6, the head of a placed key can penetrate through a key hole 61, and the cover plate 2 is in snap fit with the shell 1 to package the key handle and other components.

Slide bar storehouse 7 is equipped with buckle at two narrow limit tip of casing 1 and stretches out hole 72, is equipped with the slide bar towards key head direction and stretches out hole 71, is provided with slide bar 3 in the slide bar storehouse 7, 3 one end of slide bar are the slide bar and stretch out head 31, and the slide bar is stretched out head 31 and is cylindrical in this embodiment, and the slide bar stretches out head 31 and slide bar and stretches out hole 71 cooperation, and the slide bar 3 other end is slide bar buckle 32, slide bar buckle 32 comprises two plastics elasticity square sheets, and one of them plastics elasticity square sheet can be followed the buckle stretches out and the chucking in hole 72.

The slide bar extending head 31 is connected with the slide bar buckle 32 through a thin bar, the thin bar is provided with a spring 4, one end of the spring 4 is fixedly connected with a spring limiting piece 5, the other end of the spring 4 is fixedly connected with the slide bar buckle 32, the spring limiting piece 5 is fixedly connected with the shell 1, the slide bar 3 can move back and forth in the slide bar bin 7, and the total length of the slide bar 3 is set to be that when the slide bar buckle 32 extends out of and is clamped in the buckle extending hole 72, the end face of the extending head 31 is just flush with the plane where the extending hole 71.

The specific working principle is as follows: when in use, a key is put into the key bin 6 of the shell 1, and the cover plate 2 is fastened. When the key is not used to lock the door, the slide rod 3 is in an inactivated state (as shown in fig. 3), and at this time, under the tension of the spring 4, the slide rod protruding heads 31 on the two sides of the slide rod 3 protrude out of the slide rod protruding holes 71, and the plastic elastic square piece on one side of the slide rod buckle 32 is pressed into the slide rod bin 7. When a user locks a door by using the key, the head of the key is completely inserted into the lock cylinder, so that the slide rods 3 on the two sides are also pressed into the slide rod bin 7 at the same time, the slide rods 3 are in an activated state (as shown in fig. 4), the spring 4 is stretched at the moment, a plastic elastic square piece on the slide rod buckle 32 after moving towards the right side extends out of the buckle extending hole 72 and is clamped, and the end face of the extending head 31 at the moment is just flush with the plane where the extending hole 71 is located.

The sliding rod 3 and the shell 1 are in contrasting colors (striking colors) mutually, and a user is reminded whether to lock the door or not in the aspects of touch and vision, namely when the sliding rod 3 is in an activated state, the extending head 31 does not extend out of the extending hole 72 to indicate that the door locking action is finished, and when the sliding rod 3 is in an inactivated state, the extending head 31 extends out of the extending hole 72 to indicate that the door locking action is not executed.

After the door locking action, when the user confirms that the user locks the door, the user presses the slide rod buckles 32 on the two sides with fingers, under the pulling force of the spring 4, the slide rod 3 moves leftwards again to be in an inactivated state, the extension head 31 extends out of the extension hole 72, and the next door locking action of the key is waited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
