Description
Technical field
The utility model is a kind of pivot device, is meant between a kind of loam cake and base that is installed in lid-lifting device, with so that loam cake is able to open with respect to base, and has the pivot device of limit function.
Background technique
Lid-lifting device for example is equiped with pivot device between the loam cake of translating machine etc. and base, so that loam cake can be opened and closure with respect to base, the pivot device of prior art, be provided with relative concavo-convex positioning block, be respectively equipped with relative jog on the concavo-convex positioning block, each jog two ends all is provided with the inclined-plane, when then concavo-convex positioning block rotates relatively, jog is able to chimeric relatively reaching locating effect, when the reverse turn loam cake of user, but jog relative separation and make loam cake and base break away from the relative positioning state, yet, if the user continues to apply strength to same direction, can cause jog to be separated from each other, then loam cake excessively rotates and is easy to damage.
Summary of the invention
Because the shortcoming of aforesaid prior art, the utility model is improved the pivot device of prior art, makes it not only have locating function, also has limit function simultaneously, limits the angle of loam cake rotation, causes damage to avoid loam cake excessively to rotate.
For reaching above-mentioned purpose, the technological means that the utility model adopted is the pivot device of a kind of tool limit function of design, comprising:
One pivot, one end extend axially and form fixing rod, and the other end radially elongation moulding has a bizet, and the bizet ora terminalis forms one first cambered surface and one second cambered surface, and first and second connecting part, cambered surface two ends forms a plane respectively;
One fixing bolster, the one side is a fixing part, and opposite side is recessed positioning block, and recessed positioning block is sheathed on the pivot, and the opposite side with respect to fixing part on the recessed positioning block forms at least one location indentations, and the location indentations two ends form the inclined-plane;
One protruding positioning block, it is sheathed and be fixed on the pivot, and protruding positioning block is adjacent to recessed positioning block, and protruding positioning block forms at least one positioning convex portion with respect to recessed positioning block one side, and positioning convex portion is with respect to the location indentations of recessed positioning block, and the positioning convex portion two ends form the inclined-plane;
One rotation bolster, it is sheathed and be fixed on the pivot;
One elastic element group, it is sheathed on the pivot;
One packing ring, it is sheathed on the pivot;
One fixed block, it is sheathed to be fixed on the fixing rod of pivot.
Pivot device is installed between the base and loam cake of translating machine, and fixedly the base of the fixing part of bolster and translating machine interfixes, and the loam cake of rotation bolster and translating machine interfixes, so that loam cake is able to rotate with respect to base.
Advantage of the present utility model is, not only can be by cooperatively interacting and reach locating effect between concavo-convex positioning block, simultaneously when rotating to the location, fixedly the plane of pivot is kept out in the bolster side, make pivot can't continue rotation more in the same direction, and reach spacing effect, cause damage to avoid loam cake excessively to rotate.

Embodiment
See also shown in Fig. 1-2, the utility model includes a pivot 10, fixedly bolster 20, one protruding positioning block 30, an elastic element group 40, a packing ring 50, a rotation bolster 60 and a fixed block 70.
Aforesaid pivot 10 sections are non-circular, pivot 10 1 ends extend axially and form fixing rod 11, form screw thread 111 on the fixing rod 11, pivot 10 the other ends radially elongation moulding have a bizet 12, bizet 12 ora terminalis form one first cambered surface 121 and one second cambered surface 122, and first and second connecting part, cambered surface 121,122 two ends forms a plane 123 respectively.
Aforesaid fixedly bolster 20 is a L template body, fixedly bolster 20 1 sides are fixing part 21, opposite side is recessed positioning block 22, recessed positioning block 22 central authorities run through and form a circular hole 221, recessed positioning block 22 borrows circular hole 221 to be sheathed on the pivot 10, opposite side with respect to fixing part 21 on the recessed positioning block 22 forms two location indentations 222,223, and location indentations 222,223 two ends form the inclined-plane.
Aforesaid protruding positioning block 30 is sheathed on the pivot 10, protruding positioning block 30 is adjacent to recessed positioning block 22, protruding positioning block 30 central authorities run through and form a non-circular perforation 31, protruding positioning block 30 borrows perforation 31 sheathed and be fixed on the pivot 10, protruding positioning block 30 forms two positioning convex portion 32,33 with respect to recessed positioning block 22 1 sides, and positioning convex portion 32,33 is with respect to the location indentations 222,223 of recessed positioning block 22, and positioning convex portion 32,33 two ends form the inclined-plane.
