The slide rail 3 is in a rectangular frame shape, is fixed on the door plate by screws and is used for a sliding cover 1, a T-shaped fan blade rotating shaft 4, a one-way gear 5 and an attachment of a rolling turntable 6.

The sliding cover 1 is in a cuboid shape, is tightly occluded with the sliding rail 3 and slides on the sliding rail 3 by pushing.

The T-shaped fan blade rotating shaft 4 is provided with 4 groups from top to bottom, each group of T-shaped fan blade rotating shafts 4 comprises a T-shaped fan blade 41, a rotating shaft 42 and a password wheel 43, the rotating shaft 42 transversely penetrates through the sliding rail 3, the rotating shaft 42 is rotatably supported through a one-way gear 5 and a rolling turntable 6, the T-shaped fan blades 41 are connected with the rotating shaft 42, and the password wheel 43 is installed at one end of the rotating shaft 42.

The sliding cover convex shelves 2 are flat bulges, are positioned on the back of the sliding cover 1, face to the inner side, are four in total from top to bottom and are arranged opposite to the T-shaped fan blades.

The lower side of the sliding rail 3 is provided with a shallow opening 31 for the sliding cover convex stop 2 to pass through.

The one-way gear 5 is arranged in a left side plate of the sliding rail 3 and used for controlling the one-way rotation of the T-shaped fan blade rotating shaft 4, and the rotation directions of the 4 one-way gears are not completely consistent.

The rolling turntable 6 is arranged in the right side plate of the slide rail 3 and is used for connecting the T-shaped fan blade rotating shaft 4 and can realize rolling.

The password wheel 43 is connected with the rotating shaft 42 through a screw, and the unlocking password is changed by adjusting the relative position of the password wheel 43 and the T-shaped fan blade 41.

The rotating shaft 42 is divided into five sections, a round shaft section 421, a clamping cap 422, a square shaft section 423, a clamping groove 424 and a round shaft section 425 are sequentially arranged from left to right, a square hole 411 corresponding to the square shaft section 423 is arranged on the T-shaped fan blade 41, the T-shaped fan blade 41 is directly clamped on the square shaft section 423, a buckle 44 is clamped on the clamping groove 424, and the buckle 44 is used for fixing the T-shaped fan blade 41.

It should be noted that the installation method of the present invention is described as follows:

fixing: the slide rail 3 is fixed on the door plate by screws or is directly combined with the lock body.

Setting a password: after the relative positions of the T-shaped fan blades 41 and the rotating shaft 42 are adjusted arbitrarily, the T-shaped fan blades 41 are sleeved on the square shaft section 423 and are clamped by the buckles 44. At this time, it must be kept in mind that when the sliding cover 2 can pass through the T-shaped blade rotating shaft 4, that is, when the sliding cover 1 can slide, the corresponding indication number on the password wheel 43 is the set password. And the other three T-shaped fan blade rotating shafts 4 are adjusted in the same way, and other three passwords are set. Four in all, such as: 0,1,2,3.

The forward and reverse directions of the one-way gear 5 are selected and remembered. Note that it is necessary not to make the four one-way gears 5 turn in one direction at a time. The best scheme is two cis and two trans.

According to the original clockwise rotation or the reverse rotation direction of the one-way gear 5, the four password wheels 43 are sequentially rotated to the preset password positions, such as: 0,1,2 and 3, wherein the T-shaped fan blade rotating shaft 4 can allow the sliding cover inner convex plate 2 to pass through.

The sliding cover 1 is closed, the password wheel 43 is rotated, and the numbers are scrambled. At this time, the sliding cover convex rail 2 is blocked by the T-shaped fan blade 41 on the T-shaped fan blade rotating shaft 4, and the sliding cover 1 cannot slide. And a fully closed state is realized. And (5) finishing the installation.

The method of use of the invention is illustrated below:

the four password wheels 43 are sequentially rotated to the preset password position according to the original clockwise rotation or anticlockwise rotation direction of the one-way gear 5. Such as: 0,1,2,3. At this time, the T-shaped fan blade rotating shaft 4 can allow the sliding cover convex block 2 to pass through.

The sliding cover 1 is pushed open, the lock hole is exposed, and the lock is normally unlocked.

After unlocking, the sliding cover 1 is closed, the code wheel 43 is rotated, and the codes are scrambled. At this time, the sliding cover convex stop 2 is blocked by the T-shaped fan blade 41 on the T-shaped fan blade rotating shaft 4, and the sliding cover 1 cannot slide. But also realizes a totally closed state.

The invention can also be used for the lock protection of automobiles, cabinets, drawers and the like. The appearance shape and size are changed along with the lockset and are coordinated in proportion.

The invention is most suitable for being used as an additional device of the original lockset with a sliding cover.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
