Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of computer keyboard of fine-tuning angle, packet Operation panel 1 and protective pad 12 are included, support plate 2 is provided with below operation panel 1, and support plate 2 is internally provided with fixing groove 3, and Limiting slot 4 is provided on 3 left and right sides inner wall of fixing groove, limiting slot 4 and limited block 5 are connected with each other, and the setting of limited block 5 exists The left and right sides of threaded rod 6, and 6 lower end of threaded rod and worm gear 7 are connected with each other, and are equipped with switch block 8, and switch block 8 below worm gear 7 It is connected with each other with fixed block 9, and 8 bottom end of switch block is arranged inside fixed disk 10, worm gear 7 and worm screw 11 are connected with each other, protection Pad 12 is mounted on the bottom of fixed disk 10, and connecting shaft 13 is connected on the right side of fixed disk 10.

Connection type between limiting slot 4 and limited block 5 is to be connected together, and limited block 5 and threaded rod 6 are integral type knot Structure, limiting slot 4 are to be connected together with limited block 5, convenient for the limit to threaded rod 6, prevent threaded rod 6 from rotating.

Connection type between threaded rod 6 and worm gear 7 is to be threadedly coupled, and worm gear 7 passes through between switch block 8 and fixed block 9 Connection type be bearing connection, and the connection type between worm gear 7 and switch block 8 is welding, and threaded rod 6 and worm gear 7 are spiral shell Line connection drives threaded rod 6 to rise or fall convenient for worm gear 7 when rotation, and worm gear 7 is axis by switch block 8 and fixed block 9 Connection is held, makes switch block 8 that worm gear 7 will not be stopped to rotate when supporting worm gear 7.

It is open column shape inside fixed block 9, and 9 inside diameter size of fixed block is greater than the diameter of threaded rod 6, is convenient for Threaded rod 6 is recovered in fixed block 9 when decline.

Connection type between fixed disk 10 and support plate 2 is rotation connection, and about 2 disk easy to support adjusts the angle, from And adjust the angle of operation panel 1.

2 groups of threaded rods 6 and worm gear 7, and the company between 10 left side of 11 left end of worm screw and fixed disk are provided on the left of worm screw 11 Mode is connect as rotation connection, and 11 right end of worm screw is arranged through the right side of fixed disk 10, when being convenient for rotary worm 11, snail Bar 11 will drive the rotation of worm gear 7, to drive 6 oscilaltion of threaded rod.

Working principle: when using the computer keyboard of the fine-tuning angle, being integrally placed to keyboard on desktop first, When needing to adjust the height of keyboard, can the left side of rotating fixed disk 10 worm screw 11, worm screw 11 is when rotation It will drive 2 groups of worm gears 7 to rotate, and worm gear 7 is in the rotation, the switch block 8 of 7 lower section of worm gear can rotate in fixed block 9, fixed The worm gear 7 easy to support of block 9, but worm gear 7 will not be hindered to rotate, and when worm gear 7 will drive 6 turns of threaded rod in the rotation It is dynamic, because the center of worm gear 7 is arranged in threaded rod 6, it is threadedly coupled with worm gear 7, and the limited block 5 of the top of threaded rod 6 setting Can be moved up and down in limiting slot 4, prevent threaded rod 6 can only oscilaltion from rotating, so, when worm gear 7 drive 6 turns of threaded rod When dynamic, threaded rod 6 can only oscilaltion, worm gear 7 will not be followed to rotate；

When threaded rod 6 rises, rise inside the fixing groove 3 of support plate 2, support plate 2 will be jacked up, and supports The other end of disk 2 is rotatablely connected by connecting shaft 13 and fixed disk 10, so support plate 2 can be jacked up by threaded rod 6, in this way To adjust the angle of operation panel 1, it is adjusted the whole angle of keyboard, and the protective pad 12 of 10 bottom end of fixed disk is rubber Material, rubber material have skid resistance and flexibility, convenient for when in use, preventing displacement.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
