Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1-9, a totally closed protection box of blind bolt type keyhole comprises a box body 1 and a flip 3, wherein the flip 3 is rotatably connected with the box body 1, the side surface of the box body 1 is movably connected with a plurality of groups of blind bolts 2, and the back surface of the flip 3 is provided with a hook 4.

The blind bolt 2 is formed by combining a slide way 8, an adjusting baffle plate 9 and a blind bolt handle 12, wherein the blind bolt handle 12 transversely penetrates through the right side of the box body, the two blind bolt handles are arranged in parallel, the four blind bolt handles are arranged on the same plane, the slide way is connected with one end, which is arranged in the box body 1, of the blind bolt handle 12, the adjusting baffle plate 9 is movably connected on the slide way, a notch 13 is arranged on the adjusting baffle plate, the bottom of the notch 13 is provided with a screw hole 14, the slide way is provided with four through holes matched with the screw hole 14, and the screws penetrate through the through holes and are positioned to form four gears.

The box body 1 is made of stainless steel sheets, is in a square frame shape, is determined according to the type of a door lock, is transparent in the front and back direction, and is provided with a plurality of through holes connected with other components on the left side and the right side. Torsional spring dead lever 6 is installed to the interior top of box body 1, installs torsional spring 5 on the torsional spring dead lever 6, and the one end of torsional spring 5 is fixed on torsional spring dead lever 6, and flip 3's medial surface butt is ensured to the other end, and torsional spring 5 can semi-automatic flick flip 3. The lower part of the inner side of the box body is provided with a plurality of groups of magnetic catches 10, the back of the flip 3 is connected with an iron sheet, and the iron sheet corresponds to the positions of the magnetic catches 10 and is used for the prior suction when the flip 3 is closed so as to be beneficial to the easy drawing and resetting of the blind bolt 2.

The fixed button 7 is arranged on the back of the box body 1 and is formed by extending the box body 1, the left side and the right side are respectively two, the number of the fixed buttons is four, and the fixed button 7 is provided with small holes for fixing the whole device on a door by using screws. The left and right sides of the box body 1 are respectively inserted with a telescopic pin 11 as a connecting and rotating shaft of the flip 3.

The installation method of the present invention is described as follows:

the turning cover 3 is opened, the adjusting baffle plate 9 is translated to any gear, namely, the password is preset, and then the screw is screwed for fixing. The adjusting baffles 9 on the other three blind bolts 2 are processed in the same way; it must be remembered that the preset gears and the arrangement sequence of the adjusting baffles 9 on the various concealed bolts are four ciphers, such as: 1,2,3,4;

before the outer plate of the door lock is installed, the protective box of the invention is adjusted to the keyhole position, and then the fixing buckle 7 is fastened on the door by screws.

The right end of the blind bolt handle 12 is held, the blind bolts 2 are pulled one by one, and the notches 13 on the adjusting baffle plates 9 on the four blind bolts 2 are all adjusted to the position of the hook 4, namely filing is carried out, so that the hook 4 can be ensured to smoothly pass through the notches 13 on the adjusting baffle plates 9. At the moment, the numbers of the right ends of the four blind bolts 2 going out of the box sequentially display preset passwords, such as 1,2,3,4. The flip 3 is closed, firstly the flip is sucked by the magnetic catch 10, and then the four blind bolts 2 are pushed leftwards and completely reset, namely the digital display at the right end is reset to 0. At the moment, the hook 4 is clamped by the adjusting baffle 9, namely, a fully closed state is realized. And (5) finishing the installation.

The method of use of the invention is illustrated below:

holding one end of the blind bolt handle 12 positioned outside the box body 1, pulling the blind bolts 2 one by one, and arranging numbers at the end part of the blind bolt handle to sequentially display preset passwords, such as 1,2,3,4. At this moment, the notches 13 on the adjusting baffle 9 are all just in time at the hook position, the hooks 4 are allowed to pass through, and the outside of the flip cover 3 can be connected with mechanisms such as a handle and the like, so that the flip cover 3 can be conveniently turned, the flip cover 3 can be lifted lightly, the suction force of the magnetic touch 10 is overcome, and the flip cover 3 automatically bounces.

The keyhole is exposed, and the lock is normally unlocked.

After the door is opened, the flip cover 3 is closed, the magnetic catch 10 attracts the flip cover, then the four blind bolts 2 are completely reset, namely the digital display at the right end is 0, at the moment, the hook 4 is clamped by the adjusting baffle 9, and the totally closed state is realized.

The invention can also be used for protecting locksets of cabinets, drawers and the like.

The invention can also carry out personalized aesthetic design and customization. For example, the box body is hexagonal, octagonal and the like, and the master photo, the pet photo, the cartoon pattern and the like are pasted on the surface of the flip cover.

The invention forms the password for opening the flip 3 by freely combining the gear of the adjusting baffle 9 on the concealed bolt 2 and the hook 4, and the password combination is 4 multiplied by 4=256 password combinations. If encryption is required, more combinations can be formed, for example, four dark bolts are combined with five gears to form 4 × 4 × 4 × 4=1024 passwords, and for example, five dark bolts are combined with five gears to form 5 × 5 × 5 × 5=3125 passwords. Before unlocking, only the blind bolt 2 is pulled to ensure that the box outlet code on the blind bolt handle 12 is consistent with the preset code, and the flip 3 is lifted lightly, so that the suction force of the magnetic catch 10 is overcome, and the blind bolt can be automatically flicked to expose the keyhole. Then the key is inserted normally to unlock. After the lock is unlocked, the flip cover 3 is closed, the concealed bolt 2 is reset, and the flip cover 3 is clamped by the adjusting baffle plate 9 after being reset, so that outsiders and foreign objects cannot directly see or contact the lock hole and cannot block the lock hole, and the protection function is achieved.

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 described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
