Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
In conjunction with seeing shown in Fig. 1 to Fig. 4, an embodiment of the present utility model, a kind of rotating shaft position-limit mechanism, it includes rotating shaft
1 and erection support 2, one end of described rotating shaft 1 is provided with head 3, and the other end of described rotating shaft 1 is provided with buckle 4, described head 3 with
Described erection support 2 one end leans, described buckle 4 through described erection support 2 and around the shaft 1 axis turn an angle and
Erection support 2 other end leans.
In the present embodiment, described erection support 2 includes a substrate, the first installation portion extended from the side of substrate
21, the second installation portion 22 extended from the opposite side of substrate.Described rotating shaft 1 includes that a bar portion 11, described head 3 are arranged at bar
The one end in portion 11, described buckle 4 is arranged at the other end in bar portion 11, and described buckle 4 extends radially outward out from this end.Institute
Stating the first installation portion 21 and the second installation portion 22 is equipped with the axis hole 211,221 passed for bar portion 11, described axis hole 211,221 sets
Having the breach 212,222 passed for buckle 4, this breach 212,222 matches with the shape and size of buckle 4.During installation, rotating shaft
1 has one end of buckle 4 penetrates from the axis hole 221 of the second installation portion 22, and passes from the axis hole 211 of the first installation portion 21, this
Time, described head 3 leans with mounting bracket 2 one end (outer surface of the i.e. second installation portion 22), and described buckle 4 rotates after passing
Axle 1 axis turn an angle stagger with described breach 212 and with described mounting bracket 2 other end (the i.e. first installation portion 21
Outer surface) lean.It should be noted that when buckle 4 goes to stagger with the breach 212 on the first installation portion 21, rotating shaft 1
On axial direction restrained, be now in axial locking state, when buckle 4 goes to and breach 212 phase on the first installation portion 21
Rotating shaft during correspondence 1 is lost constraint, is now in detachable state.
Described buckle 4 includes several radial protrusions extended radially outward out, and described radial protrusion circumference is equably
It is arranged on the periphery, end in bar portion 11.So, axial force produced by radial protrusion can uniformly act on erection support 2
On, make the connection between erection support 2 and rotating shaft 1 more reliable and more stable.Concrete, this radial protrusion is symmetrically in rotating shaft 1
Periphery, end arrange two, during axial locking, rotating shaft 1 rotates about 90 degree.
The outer surface of described second installation portion 22 extends boss 23 in the periphery of axis hole 221, and described head 3 is provided around
The elastic component 31 around bar portion 11 that the fluting 32 in bar portion 11 and first end of 32 of certainly slotting extend, the second of described fluting 32
Between end and elastic component 31, there is gap 33, for coordinating with boss 23.When head 31 axis around the shaft turns on erection support 2
Time dynamic, described in described boss 23 jack-up, elastic component 31 also performs relative motion, until boss 23 be placed in fluting 32 the second end and
Gap 33 between elastic component 31, thus complete to install.During design, the angle that head 3 rotates can corresponding axial locking time shape
State, such as from about 90 degree.In the present embodiment, described boss 23 is provided with two, and two described boss 23 are installed in axisymmetrical
The outer surface of described second installation portion 22, described fluting 32 and elastic component 31 are provided with two accordingly.Wherein, described elastic component 31
It is preferably zonal and arc shell fragment.
During dismounting, only need to provoke shell fragment, rotating shaft 1, when on the buckle 4 in rotating shaft 1 and erection support axis hole 21,22
Rotating shaft during correspondence 1 can be taken out realization dismounting by breach 212,222.
Also, it should be noted for ensureing that rotating shaft 1 has good machining accuracy, use mould one-shot forming mode to make
Rotating shaft, namely described head 3 and buckle 4 be shaped in described rotating shaft 1, its material preferably employs plastics, have easy for installation,
Lightweight, the advantage that abnormal sound is little.
Above disclosed only preferred embodiment of the present utility model, can not limit this practicality with this new certainly
The interest field of type, the equivalent variations therefore made according to this utility model claim, still belong to this utility model and contained
Scope.
