Detailed Description

The present invention will be further described with reference to the following examples.

Examples

As shown in fig. 1-8, the lock is called a safety lock, mainly the whole lock has no door handle design, the door handle design is cancelled, the door handle is replaced by a panel 6, the panel 6 protrudes less, and is safer than the door handle, and is called a safety lock, the lock mainly comprises a lock core part 1, a transmission shaft 2, an inner bottom plate 3, and an outer bottom plate 4, the lock core part 1, the transmission shaft 2, the inner bottom plate 3, and the outer bottom plate 4 are all the prior art in the market, and there is no design point, and it is not described in detail herein, it is worth noting that a rotating piece 5 is linked and matched at one end or both ends of the transmission shaft 2, in this embodiment, rotating pieces 5 are arranged at both ends of the transmission shaft 2, in this embodiment, the inner bottom plate 3 and the outer bottom plate 4 are movably connected with the panel 6, and the panel 6 is connected with a driving piece 61 for driving the rotating piece 5 to rotate, when the panel 6 moves, the driving piece 61 pushes the rotating piece 5 to rotate, so that the transmission shaft 2 rotates to unlock. In the present embodiment, the driving member 61 is disposed on the inner surface of the panel 6, and in the present embodiment, the driving member 61 is a sliding slot, and the sliding slot and the panel 6 are integrated.

In order to enable the panel 6 and the bottom plate to move and not fall off, in the embodiment, a sliding fit mechanism is arranged between the inner bottom plate 3, the outer bottom plate 4 and the panel 6, and the panel 6 slides on the bottom plate through the sliding fit mechanism. In this embodiment, the sliding fit mechanism includes the protrusion 7 that is provided with the inner recess of the outer walls of the two sides of the inner bottom plate 3 and the outer bottom plate 4, the inner walls of the two sides of the corresponding panel 6 are provided with the sliding grooves 8 that are sleeved on the protrusion 7 of the inner bottom plate 3 and the outer bottom plate 4, and the sliding fit between the panel 6 and the inner bottom plate 3 and/or the outer bottom plate 4 is realized by sliding the sliding grooves 8 of the panel 6 on the protrusion 7 of the inner bottom plate 3 and/or the outer bottom plate 4. In this embodiment, the protrusion 7 may be designed to be bent along the edges of the inner bottom plate 3 and the outer bottom plate 4 to form the protrusion 7, and correspondingly, the edge of the panel 6 is bent to form the sliding groove 8.

In order to fit the panel 6 over the inner and outer bottom panels 3 and 4, the lower end of the panel 6 is provided with an open channel into which the inner and/or outer bottom panels 3 and 4 are inserted. Two panels 6 are respectively through opening on the groove cover goes into interior bottom plate 3 and outer bottom plate 4, can embolia interior bottom plate 3 and outer bottom plate 4 smoothly for panel 6 in this embodiment, this embodiment all is less than panel 6 setting with the anti-lock part height design of lock core key insertion part and lock core, guarantee that panel 6 can not touch key insertion part and anti-lock part when sliding, also realized panel 6 surfacing simultaneously, no hole groove and salient, not only improved pleasing to the eye degree, still increase the security.

In order to facilitate the opening of the door by a user, the upper end of the panel 6 is provided with a space for fingers to be embedded, and in the embodiment, the side wall of the upper end of the panel 6 is arranged in a downward inclined manner to form a space for fingers to be embedded. When the door needs to be opened, the panel 6 is pushed upwards, the key hole is exposed and then inserted into the key to unlock the door, the key is pulled out after the door lock is opened, the panel 6 is pushed downwards to the driving piece 61 to press the rotating piece 5 to enable the lock tongue 9 to be completely separated from the limit of the door frame, finally, a user drives the panel 6 to be pulled outwards by fingers to open the door, the principle of an internal door opening mode is similar to that of an external door opening mode, and the detailed explanation is omitted here.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
