Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of rotary lampshade without using aid to be just easy to use.
For achieving the above object, the utility model provides following technical scheme: a kind of rotary lampshade, comprise lampshade body and mounting seat, the tapered structure setting of cross section of described lampshade body, the little openend of described lampshade body convexes with mounting ear laterally, described mounting ear one side convexes with rotary teeth, described mounting seat is provided with for being connected and installed the mounting blocks of ear, described mounting blocks is equipped with the connecting axle for hinged mounting ear, described mounting blocks is provided with elastic component and firm piece successively with respect to mounting ear one side, described firm piece is provided with for fixing the engaging tooth of rotary teeth, between described firm piece and connecting axle, be provided with flat key.
Described rotary teeth and engaging tooth all distribute and are cirque structure respectively on mounting ear and firm piece.
Described mounting ear is fixedly connected with spill spin block, and described rotary teeth is positioned on spill spin block the side with respect to firm piece.
Described lampshade body shaft is symmetrically arranged with two mounting ears, and described mounting seat is provided with two for being connected and installed the mounting blocks of ear.
A kind of rotary lampshade, comprise lampshade body and mounting seat, the tapered structure setting of cross section of described lampshade body, the little openend of described lampshade body convexes with mounting ear laterally, described mounting ear one side convexes with rotary teeth, described mounting seat is provided with for being connected and installed the mounting blocks of ear, described mounting blocks is equipped with the connecting axle for hinged mounting ear, described mounting blocks is provided with elastic component and firm piece successively with respect to mounting ear one side, described firm piece is provided with for fixing the engaging tooth of rotary teeth, between described firm piece and connecting axle, is provided with flat key.By adopting technique scheme, connecting axle is successively through mounting blocks, elastic component, firm piece and mounting ear, make lampshade body and mounting seat hinged, rotate lampshade body, make to be sent to mounting blocks one thruster with the firm piece of mounting ear tooth engagement, elastic component is compressed and produce the elastic potential energy for firm block reset, engaging tooth and rotary teeth engagement after firm block reset, lampshade body and mounting seat are achieved a fixed connection, without using aid directly to rotate lampshade body, easy and simple to handle, be convenient to people and use.

The specific embodiment
Referring to figs. 1 through Fig. 4, the utility model rotary lampshade embodiment is described further.
A kind of rotary lampshade, comprise lampshade body 1 and mounting seat 2, the tapered structure setting of cross section of lampshade body 1, on the lateral wall of lampshade body 1 near little openend, convex with mounting ear 11, lampshade body 1 is connected with mounting seat 2 by mounting ear 11, the end face of mounting ear 11 1 sides convexes with rotary teeth 121, mounting seat 2 is provided with for being connected and installed the mounting blocks 21 of ear 11, mounting blocks 21 is equipped with the connecting axle 22 for hinged mounting ear 11, connecting axle 22 can be bolt arrangement setting, by with the coordinating of nut, realize the hinged of mounting blocks 21 and mounting ear 11, mounting blocks 21 is provided with elastic component 23 and the firm piece 24 being set on connecting axle 22 successively with respect to mounting ear 11 1 sides, elastic component 23 can be spring or rubber, can provide elastic acting force by spring or rubber, firm piece 24 is fitted with mounting ear 11 all the time, firm piece 24 is provided with for fixing the engaging tooth 241 of rotary teeth 121, between firm piece 24 and connecting axle 22, be provided with flat key 25, therefore firm piece 24 is realized slippage with connecting axle 22 by flat key 25 and is connected, firm piece 24 can carry out axial slip on connecting axle 22, but cannot circumferentially rotate.When lampshade body 1 is arranged in mounting seat 2, by connecting axle 22 being passed successively to mounting blocks 21, elastic component 23, firm piece 24 and mounting ear 11, make lampshade body 1 and mounting seat 2 hinged, by screwing nut to control the laminating degree of firm piece 24 and mounting ear 11.While using lampshade, directly rotate lampshade body 1, make to be sent to mounting blocks 21 1 thrusters with the firm piece 24 of mounting ear 11 tooth engagements, elastic component 23 is compressed and produce the elastic potential energy resetting for firm piece 24, after firm piece 24 resets, engaging tooth 241 and rotary teeth 121 engagements, achieve a fixed connection lampshade body 1 and mounting seat 2, without using aid directly to rotate lampshade body 1, easy and simple to handle, be convenient to people and use.
Described rotary teeth 121 and engaging tooth 241 all distribute and are cirque structure respectively on mounting ear 11 and firm piece 24.The rotary teeth 121 and the engaging tooth 241 that are cirque structure setting are not only conducive to increase contact area when engagement, and raising frictional force, while avoiding lampshade body 1 and mounting seat 2 fixedly, produce relative motion, and be conducive to increase the anglec of rotation, the angular range regulating when easy to use is larger.
Described mounting ear 11 is fixedly connected with spill spin block 12, and described rotary teeth 121 is positioned on spill spin block 12 side with respect to firm piece 24.Rotary teeth 121 is located on spill spin block 12, and spill spin block 12 is fixedly mounted on mounting ear 11 by screw again, makes rotary teeth 121 and mounting ear 11 be Split type structure setting, is convenient to the processing of rotary teeth 121, is conducive to reduce production costs.Because firm piece 24 is realized slippage with connecting axle 22 by flat key 25 and is connected, and firm piece 24 is fit-state setting with spill spin block 12, therefore for avoiding 25 pairs of spill spin blocks of flat key 12 to produce interference, spill spin block 12 is provided with avoids the stepped hole 122 that touches with flat key 25.
Described lampshade body 1 axial symmetry is provided with two mounting ears 11, and described mounting seat 2 is provided with two for being connected and installed the mounting blocks 21 of ear 11.Increased hinged place, be conducive to improve the steadiness while connecting, made lampshade body 1 more steady when rotating.
