Abstract
The utility model is related to a kind of rod piece cam orientation mechanism, cam and rod piece including pedestal, with handle；Rod aperture is formed on pedestal, camshaft holder is provided in rod aperture side, the camshaft is located on camshaft holder, and cam surface can contradict and the rod piece through rod aperture；It is characterized in that：Rod piece is positioned position and is provided with annular groove, and cam surface has a cambered surface recess portion, and rotation cam is cut by cambered surface recess portion in the annular groove of rod piece, the contact of the two forming face.Rod piece dexterously is positioned position for the utility model and cam surface does identical setting, realizes the face contact of the two, both increases resistance surface, and it is de- to be difficult to shake, and positioning is more reliable；And the space being deformed when rod piece is contradicted is provided, the rod piece slightly deformed strengthens the reliability of positioning；Have the characteristics that design is reasonable, simple in structure, positioning is reliable, convenient disassembly.
Description
Technical field：
It, especially can rod piece easy to disassemble the utility model is related to a kind of rod piece cam orientation mechanism.
Background technology：
It is a kind of very ripe technology using cam orientation, there is embodiment in various products.Such as number of patent application：
200310113000.4, a kind of belt supporting frame eyeball umbrella handle is disclosed, has a bottom outlet in the bottom of en-toutcas, there is control beside bottom outlet
Elbow part on hack lever can be inserted into bottom outlet by button processed and the positioning clamp of linkage；There are a ring recess, clamp automatic clamping on elbow
Enter in slot, play the role of latching, unclamp elbow；Hack lever can stretch rotation in the through hole on hack lever seat, and with band cam
Positioning.The positioning on hack lever surface is directly contradicted by cam, is easily loosened under vibration.How existing cam orientation is improved
Structure, become the utility model research object.
The content of the invention：
The purpose of this utility model is the rod piece cam orientation mechanism that a kind of rod piece of design is contacted with cam forming face.
What technical solutions of the utility model were realized in：A kind of rod piece cam orientation mechanism, including pedestal, with the convex of handle
Wheel and rod piece；Rod aperture is formed on pedestal, camshaft holder is provided in rod aperture side, the camshaft is located in camshaft holder
On, cam surface can contradict and the rod piece through rod aperture；It is characterized in that：Rod piece is positioned position and is provided with annular groove, and cam
Face has a cambered surface recess portion, and rotation cam is cut by cambered surface recess portion in the annular groove of rod piece, the contact of the two forming face.
Rod aperture on the pedestal is directed toward one side toward cam action forces and tilts a low-angle, thereby provides rod piece and is squeezed by cam
The space of compressive strain.
Rod aperture on the pedestal is blind hole.
Rod piece dexterously is positioned position for the utility model and cam surface does identical setting, realizes the face contact of the two,
Both resistance surface is increased, and it is de- to be difficult to shake, and positioning is more reliable；And the space being deformed when rod piece is contradicted is provided, slightly
The reliability of positioning is strengthened for the rod piece of deformation；Have the characteristics that design is reasonable, simple in structure, positioning is reliable, convenient disassembly.
Description of the drawings：
The utility model is described further with reference to specific legend：
Fig. 1 is rod piece cam orientation structural scheme of mechanism
Fig. 2 is rod piece cam orientation mechanism decomposition diagram
Fig. 3 is rod piece cam orientation mechanism diagrammatic cross-section
Wherein
1-pedestal, 11-rod aperture, 12-camshaft holder, 2-cam
21-handle, 22-cam surface, 23-cambered surface, 3-rod piece of recess portion
31-annular groove, 4-shaft A-inclination angle
Specific embodiment：
With reference to Fig. 1, Fig. 2 and Fig. 3, rod piece cam orientation mechanism, including pedestal 1, cam 2 and rod piece 3.
Pedestal 1, to lock on object, the support base as rod piece 3；Rod aperture 11 is formed on pedestal 1, in rod aperture
11 sides are provided with camshaft holder 12；It is different according to purposes, it is positioned such as on trolley to position the rod piece of awning, the seat
Rod aperture 11 on body is blind hole so that insertion rod piece 3 operates more convenient.It is equally applicable to, as the support of en-toutcas umbrella handle is determined
Position etc..
Such as Fig. 3, further, how much rod piece 3 can be deformed when being contradicted or being squeezed by cam 2, and especially rod piece is using all
Such as carbon fiber light material, it is even more so.For this purpose, the rod aperture 11 on pedestal 1, is directed toward one side toward 2 active force of cam and tilts
One low-angle such as the inclination angle A in Fig. 3, thereby provides the space that rod piece 3 is deformed by cam extrusion.
Cam 2, including handle 21 and cam surface 22, which has a cambered surface recess portion 23.Cam 2 passes through shaft 4
It is located on camshaft holder 12, the cam 2 of rotation, cam surface can contradict and the rod piece 3 through rod aperture.
Rod piece 3, for supporting detachable object, such as awning, eyeball umbrella；Rod piece 3 is positioned position and is provided with annular groove
31, rotation cam 2 is cut by cambered surface recess portion 23 in the annular groove 31 of rod piece, the contact of the two forming face.
Claims (3)
1. a kind of rod piece cam orientation mechanism, cam and rod piece including pedestal, with handle；Rod aperture is formed on pedestal, in rod aperture
Side is provided with camshaft holder, and the camshaft is located on camshaft holder, and cam surface can contradict and the rod piece through rod aperture；
It is characterized in that：Rod piece is positioned position and is provided with annular groove, and cam surface has a cambered surface recess portion, and rotation cam is recessed by cambered surface
In the annular groove of portion's incision rod piece, the contact of the two forming face.
2. a kind of rod piece cam orientation mechanism according to claim 1, it is characterised in that：Rod aperture on pedestal is made toward cam
