Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Shown in Fig. 5, a kind of multi-functional self-rotary rotating shaft, comprise main shaft 1, main shaft one end is fixedly connected with the first joint 2, main shaft is arranged with the second joint 3 successively to the other end from the first joint, recessedly take turns 4 and cam 5 push against mechanism 6 by elastic force and lock, recessed wheel is connected with the second joint by link arm 41, recessed take turns be positioned at cam side anchor ring on be provided with the first protuberance 42 and the first limited part 43, recessed anchor ring of taking turns between first protuberance and the first limited part is set to angle slide part 44, first protuberance is positioned at angle slide part side and is provided with guiding landslide 45, cam slides along spindle axis direction, described cam is positioned on recessed anchor ring of taking turns side and is provided with the second protuberance 51, when first joint is 0 degree with the second joint angle, the summit of the second protuberance abuts with the summit of the first protuberance, second protuberance moves along angle slide part direction, second joint side spring is converted into tube-in-tube structure 31.
Wherein, main shaft surface is provided with two parallel standstill faces 11, is provided with the spline hole 52 coordinating spline with standstill face in the middle part of cam, and machinery coordinates and plays cam and can only slide along spindle axis direction, simply and fastness is high.
The inwall of tube-in-tube structure has circumferentially been arranged alternately some recess cambered surfaces 311 and protuberance cambered surface 312, and the quantity of recess cambered surface is equal with the quantity of protuberance cambered surface and be even number, the symmetrical setting all between two of even number recess cambered surface or protuberance cambered surface.When first joint and the second joint angle are 0 degree, the axial plane 13 of main shaft is positioned at recess cambered surface, first joint and the second joint angle be 15-25 when spending the axial plane of main shaft be positioned at protuberance cambered surface and be connected with the interference of protuberance cambered surface, ensure that initial position is in 15-25 degree angular position, without any stop, by the design on guiding landslide, elastic force is coordinated to push against mechanism, when making the first joint and the second joint angle be 0 degree, cam and recessed wheel push against the axial force distribution of mechanism because of elastic force and are formed to misplace and extrude, thus form rotation, and turn between 15-25 degree, so only need manually to stir gently to complete this angular turn, time saving and energy saving, the size adjustment on landslide of wherein leading can affect the size of rotation angle.
Elastic force pushes against mechanism and comprises spring 61 and the first nut 62, and component are few easy to assembly.
Second protuberance side is provided with auxiliary landslide 53, and auxiliary landslide is connected with guiding landslide, and auxiliary landslide is arc shaped surface with guiding landslide, reduces friction when sliding, and improves working life.
Main shaft between first joint and the second joint is provided with annular stopper 12, the force providing elastic force to push against mechanism is kept out, and is convenient to assembling and produces, improve the quality of production.
The working principle of the present embodiment is as follows:
During use, first joint and the second joint are used for the product section being connected needs rotation respectively, under original state, first joint and the second joint angle are 0 degree, the summit of the second protuberance abuts with the summit of the first protuberance, elastic force pushes against mechanism and remains the active force applied along main shaft axis, and main shaft is positioned at recess cambered surface, the radius of recess cambered surface is slightly larger than the axial plane radius of main shaft, all main shafts now can not produce friction and extruding in tube-in-tube structure, stir the second joint (this sentences the second joint and sets forth as rotatable parts), cannot conflict in the summit of the second protuberance and the summit of the first protuberance, and due to elastic force push against mechanism active force exist, the second protuberance abuts so can come down with guiding, and along its domatic force, form extruding, recessed wheel is extruded rotation, angle away is got final product without the need to force, rotation angle is determined by the length on landslide of leading.
Be squeezed to after on angle slide part until the second protuberance, owing to there is no the gradient, so cannot be rotated further, now main shaft axial plane side abuts with protuberance cambered surface side, the radius of protuberance cambered surface is less than the radius of main shaft axial plane, continue hand rotation second joint as required, main shaft axial plane enters in protuberance cambered surface, abut with its interference, tube-in-tube structure is for being bent to form, it is by the elasticity of self material, can be strutted by main shaft, so now namely this tube-in-tube structure is clamped on main shaft axial plane, thus can staying at random location and keep angle angle inconvenience, stability in use is splendid.
Wherein recess cambered surface and guiding landslide coordinate, and ensure not have friction barrier in automatic rotational angle range, improve its smooth degree automatically rotated and stability in use, there is not the problems such as stuck.
Embodiment two
With the difference of embodiment one, embodiment two is that elastic force pushes against mechanism and comprises some dish-type shell fragments and the second nut.Its elasticity effect more easily adjusts, and is convenient to assemble production.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
