Embodiment of the present utility model is described below in detail, the example of described embodiment is shown in the drawings, wherein ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Below by ginseng
The embodiment examining Description of Drawings is exemplary it is intended to be used for explaining this utility model, and it is not intended that to this utility model
Restriction.
In description of the present utility model it is to be understood that term " " center ", " longitudinal ", " horizontal ", " length ", " width
Degree ", " thickness ", " on ", D score, "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward ",
The orientation of instruction such as " clockwise ", " counterclockwise " or position relationship are based on orientation shown in the drawings or position relationship, be only for
It is easy to describe this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specifically
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
The purpose of this utility model is intended to propose a kind of rotary limit device of purely mechanic mode, realizes to outside whirler
Structure is spacing in 720 degree of rotating range.Based on this purpose, the utility model proposes rotary limit device include limit base 101,
Position-limited wheel 103 and spring drive mechanism.
There are two pieces of radially projections described position-limited wheel 103 side；Described outwardly convex have certain axial width,
Circumferential thickness and circumferential angle.
The installation space of limited location wheel 103 in described limit base 101；Position-limited wheel 103 is arranged on described installation and moves
In space.Coordinated by limit shaft 102 between limit base 101 and position-limited wheel 103, limit shaft 102 is fixedly mounted on limit base 101
Installation space in, position-limited wheel 103 is rotatably assorted by bearing with limit shaft 102, and position-limited wheel 103 can be around limit shaft 102
Axis both clockwise or rotate counterclockwise.
Have, in described installation space, a constraint platform being in position-limited wheel 103 axis both sides, constraint platform can be with
The outwardly convex contact of homonymy, constraint position-limited wheel 103 rotates, and when constraint platform is contacted with homonymy outwardly convex, Ling Yixiang
Outer lug stretches out described installation space, plays position-limiting action to outside rotating mechanism.
Described spring drive mechanism includes being arranged on the described spring bottom plate 106 installed in space, is arranged on
The spring upper mounted plate 104 of position-limited wheel end face, and spring 105.Spring 105 is in extended state, and two ends are subject to fixing under spring
Plate 106 and spring upper mounted plate 104 constrain.In the present embodiment, when two pieces of spacing wheel side radially raised in described peace
In dress space in an intermediate position when, spring tension position crosses position-limited wheel central axis it is achieved that spring drive mechanism
Position-limited wheel 103 can be driven to rotate, and remain that some outwardly convex is constrained the function of platform constraints by homonymy.
When being that a kind of rotary limit device of this utility model is applied as shown in Figure 3, it is in structure during rotation zero-bit and shows
It is intended to, now the left side outwardly convex on position-limited wheel 103 has blocked block 5, and so that rotating part can not be rotated counterclockwise can only be suitable
Hour hands rotate；Accompanying drawing 4 show schematic diagram during this utility model embodiment rotating part dextrorotation three-sixth turn, rotating part
Divide and turned clockwise 360 degree, block 5 is contacted with the left side outwardly convex on position-limited wheel 103, and overcome the power of spring generation
Square, makes spring tension position cross spacing wheel axis, thus under spring tension effect, position-limited wheel rotates further, until
The constraint contact with platform of the left side outwardly convex on position-limited wheel 103 and homonymy, now the right side outwardly convex on position-limited wheel 103 stretch
Go out described installation space.Accompanying drawing 5 show this utility model embodiment turn clockwise 720 degree when schematic diagram, now
Right side outwardly convex on position-limited wheel 103 has blocked block 5, and so that rotating part can not be rotated clockwise can only rotate counterclockwise.
Mechanism in Fig. 3 mainly includes installing stopping means 1 on a base plate 2, can be around the mechanism of mechanism's rotary shaft 3 rotation
Swivel mount 4, also includes the block 5 being connected on mechanism's swivel mount 4.During assembling, stopping means 1 are affixed on base plate 2, and mechanism revolves
Rotating shaft 3 is affixed on base plate 2, and mechanism's swivel mount 4 passes through bearing bindiny mechanism rotary shaft 3 and can rotate about, and block 5 is affixed to
On mechanism's swivel mount.
As Fig. 3, mechanism's swivel mount 4 drives block 5 to start to turn clockwise, and when rotating 360 degrees, block 5 is touched
The left side outwardly convex of position-limited wheel 103, left side outwardly convex is fitted with the left side constraint platform of limit base 101, position-limited wheel 103
Right side outwardly convex is holded up；Mechanism's swivel mount 4 continues to turn clockwise, when rotating to 720 degree, the position-limited wheel 103 holded up
Right side outwardly convex blocks the continuation rotation of block 5, realizes spacing clockwise.When mechanism's swivel mount 4 rotate counterclockwise, former
Reason ibid, is realized spacing counterclockwise.
Although of the present utility model embodiment has been shown and described above it is to be understood that above-described embodiment is
Exemplary it is impossible to be interpreted as that those of ordinary skill in the art is without departing from this utility model to restriction of the present utility model
Principle and objective in the case of above-described embodiment can be changed in the range of this utility model, change, replace and
Modification.
