The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are elaborated:

Referring to computer keyboard tray shown in Figure 1, mainly consisted of by bracing frame 2 and the swinging mounting 1 that is supported on the support frame as described above 2, support frame as described above 2 plays the effect of support, four feets 3 of bracing frame 2 bottoms play with desktop and contact and fixing effect, the top of described support 1 holds keyboard, described swinging mounting 1 rotates with bracing frame 2 and arranges, and rotating shaft is perpendicular to the opposite face of the two.The angle adjustment of keyboard can be arrived suitable position by rotation swinging mounting 1.

Be provided with position-limit mechanism between support frame as described above 2 and the swinging mounting 1, position-limit mechanism comprises: be positioned at triangular groove 21(on the bracing frame 2 referring to Fig. 4), be positioned at the convex tendon 11(of swinging mounting 1 bottom referring to Fig. 5).Referring to Fig. 3, when swinging mounting 1 relative bracing frame 2 was positioned at the first extreme position (closure), convex tendon 11 was resisted against the first trough rim that triangular groove 21 is positioned at the left side.Referring to Fig. 1, when swinging mounting 1 relative bracing frame 2 was positioned at the second extreme position (opening fully), convex tendon 11 was resisted against the second trough rim that triangular groove 21 is positioned at the right side.This state can help operating personnel easier, use shortcut more like a cork, and wrist that needn't excessive distortion oneself.Reasonable angle setting between two extreme positions need to be taken into account user's use habit and comfortableness, the inventor is by survey, obtained feedback and the suggestion of computer operater to keyboard drawer, and on this basis design angle is revised repeatedly, angle is decided to be 35 ° the most at last, and scheme has obtained consistent favorable comment.

Be welded with Λ type shell fragment 22 on the support frame as described above 2, it at first is used for bracing frame 2 is remained on the first extreme position or the second extreme position.Λ type shell fragment 22 can auxiliary rotary support 1 afterwards, turns to extreme position pushing through half stroke angle (housing of swinging mounting 1 is through the summit of Λ type shell fragment 22), realizes regulating.Because when the housing of swinging mounting 1 contacts with Λ type shell fragment 22, Λ type shell fragment 22 compressed and generation screen resiliences force swinging mounting 1 to turn to the first extreme position or the second extreme position.

Referring to Fig. 5, described swinging mounting 1 is roughly frame structure, takes into account the utilization rate of weight and material in proof strength and stability, and some reinforcements 12 are set in the framework.Keyboard places in the framework, and the frame of swinging mounting 1 outmost turns epirelief then can be placed and sensing positioning keyboard effectively.Put into and take out keyboard for the ease of people in the process of using, the inboard of swinging mounting 1 housing offers the open slot 13 of rectangle, can hold finger in it.
