Detailed Description

The technical scheme of the invention is further explained by combining a schematic diagram.

As shown in fig. 1, the invention is a keyboard tray with adjustable angle, comprising a tray body 1, a tray shell 2, a spring hook 3, an angle adjuster 4 and a positioning device 5. Tray body 1 nestification is in tray shell 2, and the both sides of tray body 1 one end are connected at the both sides inner wall of tray shell 2 through pivot 6, can rotate through pivot 6.

As shown in fig. 2, the angle adjuster 4 includes a top rod 41, a positioning column 4, a spring 45, a gear 43 and a guide wall 44, the top rod 41 contacts with the lower surface of the tray body 1, the top rod 41 is placed in the positioning column 42, the positioning column 42 is fixed on the bottom plate inside the tray housing 2 to support the tray body 1, the spring 45 is placed in the positioning column 42 and contacts with the inner surface of the downwardly extending side wall of the top rod 41, and the spring 45 jacks up the top rod 41 to support the tray body 1. The positioning column 42 is provided with a positioning pin 46 for limiting the rising height of the push rod 41 near the upper port of the tray body 1. The outer surface of the positioning column 42 is attached with a gear 43, one side of the gear 43 is provided with a guide wall 44 which is vertically attached to the outer surface of the positioning column 42, the guide wall 44 is in seamless joint with one side edge of the gear 43, and the part of the guide wall 44 which extends downwards beyond the gear 43 is in an arc shape towards one side of the gear 43. Attachment means include bonding, welding or integral formation with the locating post 42.

As shown in fig. 1, the positioning device 5 fixes one end of the spring hook 3 at the bottom of the tray body 1, and the other end is a hook structure capable of hooking the lower surface of each tooth of the gear 43; when the tray body 1 is in a horizontal state, one end of the hook body of the spring hook 3 is in contact with the intersection of the first saw tooth 431 of the gear 43 and the guide wall 43.

When using, press tray body 1 through keyboard 7, tray body 1 rotates downwards through

pivot

6, 41 atress of ejector pin, compression spring 45, spring hook 3 receives tray body 1 pressure next sawtooth to slide, stop pressing after tray body 1 rotates suitable angle, spring 45 atress disappears, spring 45 receives self elasticity and begins to bounce-back, ejector pin 41 receives elasticity jack-up tray body 1 that makes progress, tray body 1 drives spring hook 3 upward movement, 3 coupler bodies of spring hook gear 43 last sawtooth lower limb this moment, tray body 1 receives the pulling force of spring 45 elasticity and spring hook 3 to keep current angle balance.
