Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, a kind of mechanical computer USB slot protective device, including protective shell 2, the protective shell 2 are side
The cavity of face opening, 2 left side top and the bottom of protective shell are bonded a double-sided adhesive 5 respectively, and double-sided adhesive 5 connects cabinet panel 1, using double
The connection type of face glue can allow the present invention not need additionally to add bindiny mechanism, so that it may easy by protective shell
It is fixed on host computer；The hole cabinet USB 6 is installed, the 2 bosom position of protective shell is equipped with double among cabinet panel 1
Head USB plug 7, is the USB male joint for being directly inserted into the hole cabinet USB 6 on the left of double end USB plug 7, and right side is that connection USB is inserted
The USB female 12 of head, centre increase the intensity of connector to greatest extent, improve without the connection transmission of other data lines
Use reliability of the invention；7 top and the bottom of double end USB plug are slidably connected the first rack gear 8, and the first rack gear 8 is with tooth one side
Gear 9 is installed, gear 9 is fixed on protective shell inner wall by the first fixed rotating shaft 10, is equipped at the top of the protective shell 2 antitheft
Knob 20, antitheft 20 lower part of knob install the second rack gear 11, install reset spring 4 between 11 left side of the second rack gear and protective shell 2,
Limited block 3 is installed on the left of 2 top and the bottom of protective shell, second hinge 19, second hinge 19 are installed on the right side of second rack gear 11
Second lever 17 is installed on the right side, 17 right end of the second lever installs first axle 16, and first axle 16 installs the first lever 14, the
One lever 14 is fixed on protective shell inner wall by the second fixed rotating shaft 15；First rack gear 8 is tightly attached to double end USB plug 7
Top and the bottom, it is therefore prevented that the phenomenon that plugging stress deflection during USB plug 12, double end USB plug 7 is caused to be bent.
Referring to Fig. 2, installing second dust-proof piece 18 at 2 right openings of protective shell, first lever 14 is freely lived
Moved end installs first dust-proof piece 13, and described first dust-proof piece 13 and second dust-proof piece 18 is all made of rubber material, works as closure of openings
When, second dust-proof piece 18 contacts with the second lever 17, and first dust-proof piece 13 contacts with each other, and protective shell 2 is fully sealed, and prevents outer
Portion's dust enters cabinet inside；When first dust-proof piece 13 closure, the second rack gear 11 touches limited block 3, prevents due to multiple
Second rack gear 11 is pulled away from initial position by position spring 4, leads to the first lever 14 reversely opening.
Referring to Fig. 3, the antitheft knob 20 be can with the cylindrical structure of 2 relative rotary motion of protective shell, it is antitheft
20 bottom of knob is provided with a word sliding slot, has at the top of second rack gear 11 sliding with the protrusion of antitheft one word sliding slot of knob bottom cooperation
Block, when antitheft knob rotation 20 go to flat recess or so towards when, the boss slider at the top of the second rack gear 11 can be along antitheft rotary
The flat recess of button 20 slides, and the first lever 14 can be pushed at this time, and double end USB plug 7 can be inserted in USB plug 12, on the contrary
USB plug 12 can not be inserted into double end USB plug 7, to play anti-theft function.
The present invention, in use, when the USB plug 12 is inserted into double end USB plug 7,14 left end quilt of the first lever
It is lifted to upper left side, does lever action around the second fixed rotating shaft 15,14 right end of the first lever moves to the right, the movement side
Formula is conducted by first axle 16 to the second lever 17, and the second lever 17 is moved to the right, passes through second hinge 19, the second thick stick
Bar 17 drives the second rack gear 11 to move together to the right, and the second rack gear 11 moves right band moving gear 9 around fixed rotating shaft one
10 do clockwise movement, so that the first rack gear 8 be driven to move downward, double end USB plug 7 is contacted with USB plug 12 at this time, complete
The movement of entire insertion USB plug 12；When USB plug 12 is extracted, reset spring 4 pulls the second rack gear 11 to the left side, from
And causes the first rack gear 8 to move to the right and cover all double end USB plug 7, and the first lever 14 and the second lever 17 are all
It is moved to opposite direction, closure of openings is lived；By the lever and gear & rack structure of Purely mechanical, protective device opening is completed
On-off action, related movement when entire movement only needs to plug USB plug 12 can be completed, do not need to be additionally provided other
Power supply and electric control structure, it is easy to operate, it is easy for installation；First rack gear 8 is tightly attached to the top and the bottom of double end USB plug 7, prevents
The phenomenon that having stopped stress deflection during plugging USB plug 12, double end USB plug 7 caused to be bent.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
