The turning handle mechanism comprises a turning handle (4) and a machine enclosure, and is characterized in that the turning handle (4) is in rotational connection with the machine enclosure by an outer tooth ring (5) with inner teeth, an inner tooth ring (3) for limiting the rotating angle of the outer tooth ring (5) and having capability of meshing or disengaging the outer tooth ring (5) is connected on the outer tooth ring (5), an inner tooth ring sliding guide rod (9) is inserted at the center of the inner tooth ring (3), a button (2) is arranged at one end of the inner tooth ring (3), the other end of the inner tooth ring (3) pushes against the machine enclosure through a spring (8), and the inner tooth ring sliding guide rod (9) is in screwed connection with a fastening bolt (7) on the machine enclosure.
Description
Technical field
The utility model relates to a kind of turning handle mechanism, but specifically is meant a kind of turning handle mechanism that is used for the gyration locking on the garden instrument.
Background technology
Garden instrument all can consider to use rotary handle or rotary machine working portion in order to fit in consumer's comfort better during design, the function of better performance instrument when ensureing user's operation comfort.In the prior art there be much common rotational structure, hinged such as handle and machine body, and the degree of tightness of the bolt by pin joint locks the anglec of rotation, and obviously such structure locking ability is not strong, loosening easily, poor reliability.The buckle structure of step positioning type is provided with the different draw-in groove of a plurality of angles on machine body for another example, and handle directly snaps in the different draw-in grooves according to user's needs, this structure angular transformation inconvenience, and the scope that variable-angle changes is little.In sum, turning handle of the prior art mechanism angle adjustment inconvenience, poor reliability.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of angle adjustment convenient, but the turning handle mechanism of the gyration of good reliability locking.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: but the turning handle mechanism of a kind of gyration locking, it comprises turning handle and casing, turning handle is rotationally connected by external toothing and the casing that is provided with internal tooth, be connected with on the external toothing be used to limit the external toothing rotational angle can with external toothing engagement or the ring gear of throwing off, the center of ring gear is inserted with the ring gear sliding guide; One end of ring gear is provided with button, and the other end offsets by spring and casing, and the fastening bolt on ring gear sliding guide and the casing is spirally connected.
After adopting above structure, the utlity model has following advantage: turning handle and casing are rotationally connected by gear ring structure, but and be provided with corner in the gear ring and lock the Control Component of corner, than turning handle structure of the prior art, only Control Component need be pressed during adjusting, unclamp after rotating corresponding angle, Control Component can be automatically reseting under the effect of spring the angle locking after having regulated is lived, and easy to adjust, gears engaged connects simultaneously, be difficult for skidding good reliability.
As improvement, the upper end outer peripheral face of described button is connected by overhead structure and casing are spacing.This structure can prevent effectively that button from coming off from casing, and the fluking type designing user can not can prevent that child from destroying turning handle mechanism directly with the button dial-out from the outside.
As improvement, also be provided with on the end that described ring gear links to each other with button and be used to limit ring gear and go out the back-up ring of external toothing from button one end motion, described back-up ring is fixedlyed connected with casing.The activity upper limit of ring gear can be better controlled in the design of back-up ring, when preventing that spring force is big ring gear is ejected external toothing.
Description of drawings
But Fig. 1 is the structural representation of the turning handle mechanism of the utility model gyration locking.
As shown in the figure: 1, upper casing, 2, button, 3, ring gear, 4, turning handle, 5, external toothing, 6, lower casing, 7, fastening bolt, 8, spring, 9, the ring gear sliding guide, 10, engaging piece, 11, back-up ring.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
In conjunction with the accompanying drawings 1, turning handle 4 is rotationally connected with casing by the external toothing 5 that is provided with internal tooth, an end that is turning handle 4 is fixedlyed connected with external toothing 5, external toothing 5 turning sets are connected on the casing, be connected with on the external toothing 5 be used to limit external toothing 5 rotational angles can with external toothing 5 engagements or the ring gear 3 of throwing off, the center of ring gear 3 is inserted with ring gear sliding guide 9; One end of ring gear 3 is provided with button 2, and the other end offsets by spring 8 and casing, and the fastening bolt 7 on ring gear sliding guide 9 and the casing is spirally connected.The upper end outer peripheral face of described button 2 is connected by overhead structure and casing are spacing.Also be provided with on described ring gear 3 and the end that button 2 links to each other and be used to limit ring gear 3 and go out the back-up ring 11 of external toothing 5 from button 2 one end motions, described back-up ring 11 is fixedlyed connected with casing.
The utility model in the specific implementation, described casing generally is connected by screw with lower casing 6 by upper casing 1 or clamping forms an integral body, further combined with accompanying drawing 1, in order to ensure the angle locking intensity between turning handle 4 and the casing, the strength ratio of the engaging piece 10 between the external tooth on internal tooth on the external toothing 5 and the ring gear 3 is crucial, so can adopt the bigger stepped tooth of intensity.Though need to prove the concrete structure that the casing in the accompanying drawing draws, but this is a kind of embodiment, when reality is used, the structure of casing can be diversified, that is to say that it can be other main casing that garden instrument of turning handle need be installed, be used for the structure of docking with turning handle as long as be equipped with on the main casing.
More than the utility model and embodiment thereof are described, this description does not have restricted, shown in the accompanying drawing also is one of embodiment of the present utility model, practical structure is not limited thereto.If generally speaking those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to protection domain of the present utility model without creationary frame mode similar and the embodiment of designing to this technical scheme.
