All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, in the embodiment of the present invention, a computer keyboard device used specially comprises a keyboard body 1, a connecting wire 2 is fixedly connected to the left side of the keyboard body 1, a cover plate 4 is movably connected to the top of the keyboard body 1, an inner groove 24 is formed in the bottom of the cover plate 4, a key 3 located in the inner groove 24 is movably installed at the top of the keyboard body 1, a first circular shaft 5 is fixedly installed on the right side of the front and back of the keyboard body 1, a movable sleeve 6 is movably sleeved on the outer surface of the first circular shaft 5, a second circular shaft 8 is fixedly installed in the middle of the front and back of the cover plate 4, a rotary sleeve 9 is fixedly sleeved on the outer surface of the second circular shaft 8, a sleeve 10 is fixedly installed on the right side of the lower surface of the rotary sleeve 9, a movable rod 7 is movably sleeved inside the sleeve 10, the other end of the movable rod 7 is fixedly connected to the outer surface of the movable sleeve 6, an installation shaft 11 is fixedly installed on the right side of the front and back of the cover plate 4, the fixed cover in surface of installation axle 11 has been connected with circle cover 12, and the other end fixed mounting of circle cover 12 has connecting block 13, and the quantity of connecting block 13 is two, and the equal fixed mounting of the other end of two connecting blocks 13 has support frame 14, the internal surface of support frame 14 and the surface swing joint of apron 4 right-hand members.

Wherein, the equal fixed mounting in front and the back of apron 4 has the fixed block 15 that is located the left of round cover 12, the right side of fixed block 15 and the surface swing joint of round cover 12, and the surface on fixed block 15 right side and the surface of round cover 12 are all smooth to make round cover 12 more smooth and easy at rotatory in-process.

Wherein, the front of fixed block 15 has seted up long mouthful 17, and the inside of fixed block 15 has seted up interior mouth 16, and the inside activity of interior mouth 16 is cup jointed the motion piece 18, and the cross-sectional area of motion piece 18 side is the same with the cross-sectional area of interior mouth 16 side to it is more stable to make the motion piece 18 can move about in interior mouth 16.

Wherein, draw-in groove 21 has been seted up to the surface on round cover 12 right side, and the quantity of draw-in groove 21 is five, and five draw-in grooves 21's size is the same, because the design of five draw-in grooves 21, when round cover 12 is at rotatory in-process, can make fixture block 22 block in the draw-in groove 21 of different positions.

Wherein, the front fixed mounting of motion piece 18 has connecting axle 19, and the other end of connecting axle 19 passes long mouthful 17 and extends to the outside of fixed block 15 and fixed mounting has and draws piece 23, when operating personnel pulling draws piece 23, will make connecting axle 19 drive motion piece 18 take place the motion, and finally fixture block 22 can break away from the inside of draw-in groove 21, and then removes the fixed effect to round cover 12.

Wherein, the right side of the motion block 18 is fixedly connected with a rigid spring 20, and the other end of the rigid spring 20 is fixedly connected with the inner wall of the inner opening 16, and due to the design of the rigid spring 20, the motion block 18 and the fixture block 22 have good elastic resetting capability.

Wherein, the left side fixedly connected with fixture block 22 of motion piece 18, the left end of fixture block 22 runs through fixed block 15 and extends to the inside of draw-in groove 21, because the cooperation between fixture block 22 and the draw-in groove 21, can play good fixed action to circle cover 12, avoids it to take place unexpected deflection.

The two rigid springs 20 are in a compressed state, so that an elastic force is applied to the moving block 18 and the latch 22, and the left end of the latch 22 can be firmly clamped in the clamping groove 21.

The distance between the inner parts of the long openings 17 is equal to the diameter of the connecting shaft 19, the connecting shaft 19 is cylindrical, and the outer surface of the connecting shaft 19 and the inner wall of the long openings 17 are smooth, so that the connecting shaft 19 can slide smoothly.

The working principle and the using process are as follows:

because the design of apron 4, can block external dust, avoid external dust to fall into among the top of keyboard body 1 and the clearance of button 3, when the user needs to use button 3, the user can pull apron 4 this moment, make apron 4 wholly use first circle axle 5 to send out the rotation as the axle center, and at rotatory in-process, can make apron 4 wholly use second circle axle 8 to rotate as the axle center, avoid the surface of apron 4 and the surface of keyboard body 1 to touch mutually and block, end user can remove keyboard body 1 wholly to make it use second circle axle 8 to rotate as the axle center, the bottom of final keyboard body 1 will contact with the top of apron 4, then can carry out normal use.

When a user needs to adjust the supporting angles of the keyboard body 1 and the cover plate 4, the pull block 23 can be pulled rightwards, so that the connecting shaft 19 drives the moving block 18 and the clamping block 22 to move rightwards, the rigid spring 20 is in a compressed state at this time, and the left end of the clamping block 22 is separated from the inside of the clamping groove 21, so that the fixing effect on the round sleeve 12 can be relieved, then the user can pull the supporting frame 14, so that the supporting frame 14 rotates by taking the mounting shaft 11 as an axis, after the supporting frame 14 rotates to a proper angle, the user can release the pull block 23, at this time, due to the elastic force recovery effect of the rigid spring 20, the moving block 18 drives the clamping block 22 to be clamped into the corresponding clamping groove 21, so that the fixing effect on the round sleeve 12, the connecting block 13 and the supporting frame 14 can be formed, so that the accidental deflection of the supporting frame 14 is avoided, and then the bottom of the supporting frame 14 can be placed on a desktop, therefore, the keyboard body 1 and the cover plate 4 can be obliquely supported, and the operation of a user is facilitated.
