Abstract
The utility model relates to a pivot which comprises a supporting rack fixed on a fixing component and a rotary axle, wherein, the supporting rack is provided with a through hole of the rotary axle; one end of the rotary axle can be connected with a pivoting component, and the center part of the rotary axle is provided with an axial positioning flange. The utility model is characterized in that a group of disc-shaped spring pieces, locking screw nuts and positioning pieces positioned on both ends of the group of the disc-shaped spring pieces are sheathed on the other end part of the rotary axle passing through the through hole of the rotary axle of the supporting rack. The positioning pieces and the locking screw nuts can rotate synchronously with the rotary axle. When the rotary axle rotates, the positioning pieces and the disc-shaped spring pieces rotate with the rotary axle. When the rotary axle stops rotating, the rotary axle is positioned on a rotating angle because of the pushing force of the disc-shaped spring pieces.
Description
The utility model relates to a kind of pivot, particularly a kind of pivot that makes pivot member can keep the location on arbitrary corner.
Patent Office of the People's Republic of China has once published one piece of application number on July 24th, 91 and has been called " pivot " for the 902244167(name) utility application bulletin.This pivot comprises bolster, is nested in the axle sleeve on the bolster and is sheathed on the interior rotating shaft of axle sleeve, and an end of rotating shaft can be for being connected on the pivot member, and the other end then is arranged with spring, location piece and clamping nut.Because force in the effect that the spring on the bolster pushes up the tension force of pulling, this pivot can make rotating shaft locate on any rotation angle.Its major defect is: (1) part is more, and volume is big; (2) stage clip life test number of times is less, thereby has influenced the operating life of hinge mechanism.
The purpose of this utility model is that a kind of pivot that makes pivot member can keep the location on arbitrary corner will be provided, and it not only constructs compactness, and volume is little, and long working life.
The utility model comprises that the bolster with rotating shaft through hole and the end that are fixed on the fixed component can be for the rotating shafts that is connected on the pivot member.Rotating shaft middle part is provided with the axially locating flange, and the characteristics of its structure are that rotating shaft is passed on the other end of bolster rotating shaft through hole and is arranged with one group of cup spring sheet, is positioned at the location piece and the lock nut that can rotate synchronously with rotating shaft at these group cup spring sheet two ends.
The utility model one is because cast out axle sleeve and substituted stage clip with the cup spring sheet of the little favorable working performance of volume; The 2nd because the two ends of cup spring chip module can be clamped with the location piece that rotating shaft is rotated synchronously, when rotating shaft when bolster rotates, the cup spring sheet can not worn and not torn mutually by twisting, thereby has guaranteed that the cup spring sheet carries out work under preferable operating mode; Therefore it is compact to have structure, and volume is little, remarkable advantages such as long working life.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model structure view.1 is bolster and the joining mounting hole of fixed component among the figure; 2 are rotating shaft and the joining mounting hole of pivot member.
Fig. 2 is a location piece structure view.
Fig. 3 is a rotating shaft structure view; Fig. 4 is the plan view of Fig. 3; Fig. 5 is the A-A sectional view of Fig. 4.
Fig. 6 is sheathed on component in the rotating shaft schematic representation that puts in order.
With reference to accompanying drawing, the utility model comprises bolster 3 and the rotating shaft 5 that is placed through on the bolster rotating shaft through hole 4.Rotating shaft middle part is provided with axially locating flange 6, and rotating shaft is passed on the other end of bolster rotating shaft through hole and is arranged with one group of cup spring sheet 7, is positioned at the location piece 8 and the lock nut 9 that can rotate synchronously with rotating shaft at these group cup spring sheet two ends.The location piece endoporus is cydariform.The other end that bolster rotating shaft through hole is passed in rotating shaft has and is positioned at the inboard necked part 10 that matches with the rotating shaft through hole 4 of bolster and is the axis body 11 of cydariform with the corresponding cross section of location piece endoporus, and the axis body outside is provided with and the corresponding outside thread 12 of lock nut.
In order to reduce friction, the both sides of bolster (rotating shaft through hole) are provided with pad 13.
When driving rotating shaft 5 rotations under the effect of pivot member in external force, location piece 8 and cup spring sheet 7 just rotate thereupon; When pivot member stops operating, because the effect of the top system power of cup spring sheet then makes rotating shaft and pivot member be positioned on this corner.
The utility model is not only constructed compactness, and cost is low, and easy to use, long working life.Its application prospect is considerable.
Claims (2)
1, a kind of pivot comprises the bolster with rotating shaft through hole that is fixed on the fixed component, with an end can be for being connected in rotating shaft on the pivot member, the rotating shaft middle part is provided with the axially locating flange, it is characterized in that rotating shaft is passed is arranged with one group of cup spring sheet on the other end of bolster rotating shaft through hole, be positioned at the location piece and the lock nut that can rotate synchronously with rotating shaft at these group cup spring sheet two ends.
2, pivot according to claim 1, it is characterized in that the location piece endoporus is cydariform, the other end that bolster rotating shaft through hole is passed in rotating shaft has and is positioned at the inboard necked part that matches with bolster rotating shaft through hole and is the axis body of cydariform with the corresponding cross section of location piece endoporus, and the axis body outside is provided with and the corresponding outside thread of lock nut.
