Fig. 1 to Fig. 7 is a kind of based on rotating the structure realizing assembling between main frame 1 and diatery supplement cup 2, therefore, be that main movement form describes the first embodiment hereinafter with rotation, and auxiliary straight line motion realizes the embodiment of assembling as aid illustration, based on rotating the structure described, those skilled in the art can know without the need to paying creative work the configuration mode realizing interlock in the food processor of assembling at rectilinear motion on the basis of auxiliary description.
Diatery supplement cup handle 21 is conventional design of diatery supplement cup 2, and it is known, diatery supplement cup handle 21 is generally ear type structure setting up and down, so all need transmission to realize associating of main frame 1 and diatery supplement bowl cover 3 for main frame 1 and the diatery supplement cup 2 of two kinds of assembly relations, structurally, by the interlocking mechanism's solid line association being positioned at diatery supplement cup handle 21 cavity volume.
Diatery supplement cup handle 21 grasps for being conducive to, and generally possesses relatively large cross section, thus, when constructing cavity body structure, can not affect its realization as handle function to weakening of its structural strength.
As depicted in figs. 1 and 2, for the assembling meeting interlocking mechanism is arranged, diatery supplement cup handle 21 is assembly structures, and its major part is the diatery supplement cup handle 21 be fixedly connected with diatery supplement cup 2 as main body, and another major part is the handle cover 5 shown in figure.
Diatery supplement cup handle 21 is for having the trench structure at the end and two side, handle cover 5 is fitted to the notch of trench structure, and forms cavity volume, and this cavity volume is for installing described interlocking mechanism, other annexes of this safe food-processing machine also can be installed, even for laying such as cable.
Connection between diatery supplement cup handle 21 and handle cover 5 can adopt connector to realize connecting, such as connected by screw, and in certain embodiments, both self are furnished with syndeton, such as monolateral button is set at handle cover 5, and the monolateral catching groove buckled is set on diatery supplement cup handle 21, realize fastening.
About described interlocking mechanism, it comprises lock section and driving section, and lock section mainly contains two, and it is upper underdrive that first of driving section is formed, such as, gangbar 4 shown in Fig. 2.Gangbar 4 drive by the boss 11 shown in Fig. 2 realization to move upward, the first spring 6 then remove for drive end after the downward reset of gangbar 4.
The foundation structure of the gangbar 4 shown in Fig. 1 and Fig. 2 is the structure of profiling diatery supplement cup handle 21, in certain embodiments, the optional two power bars with up-down structure of gangbar 4, and in a first embodiment based on rotating the upwards driving realized it, and adopt direct linear pushing in a second embodiment.
In a first embodiment, boss 11 has the boss guiding surface 111 arranged along main frame 1 circumference, based on the diverse location of this boss guiding surface 111 in main frame 1 circumference, the bearing height of this boss guiding surface 111 is inconsistent, thus when realizing the assembling of diatery supplement cup 2 and main frame 1 based on rotation, diatery supplement cup handle 21 can change with the relative position of boss guiding surface 111, and cause the distance of vertical direction corresponding points to change, realize turning to the conversion of rectilinear motion, its principle and cylindrical cam structure similar.
In this, alternatively, in certain embodiments, can in the position setting unit cylindrical cam structure corresponding to diatery supplement cup handle 21 of main frame 1.Correspondingly, gangbar 4 forms the driven member of cam mechanism.
Gangbar 4 is as driven member, and driven member in other words, for obtaining the motion determined, its needs are directed to spacing.
On the one hand, gangbar 4 needs, by spacing up and down, to form top dead centre and the lower dead center of its impulse stroke, and in holding cavity structure as illustrated in fig. 1 and 2, the spacing up and down of gangbar 4 can be directly spacing for chamber wall institute.
Another aspect, gangbar 4 needs to be directed to, that determines with acquisition moves up and down, because gangbar 4 is bar part, and at mechanical field, the guide frame of bar part is the simplest guide frame, conventional, the guide frame based on shaft hole matching is the most common, and understandable, moving sets is the most basic kinematic pair in machinery, realizes the guiding that gangbar 4 moves up and down and namely can be replaced the mobile restraining structure of mechanical field to moving sets based on this without the need to paying creative work.
The basic exercise of gangbar 4 moves up and down, namely the motion on vertical direction, the motion of the longitudinal direction on drawing as illustrated in fig. 1 and 2, what realized by another main member of interlocking is the motion of horizontal direction, limiting bracket 8 such as shown in Fig. 4, what realized is transverse movement in Fig. 2 shown in drawing, essence is the movement in the radial direction of diatery supplement bowl cover 3, thus in a first embodiment, its impulse stroke is the impulse stroke in the radial direction at diatery supplement bowl cover 3, and the stop of this impulse stroke is centrifugal side stop and centripetal side stop.By the restriction of diatery supplement cup handle 21 holding cavity structure, the restraining structure of centrifugal side stop and centripetal side stop all can be configured to the wall of diatery supplement cup handle 21, also can assist other restraining structures.
Limiting bracket 8 is the component that moves upward of constraint gangbar 4, is again to be limited part under set condition.
Visible in following structure: gangbar 4 when diatery supplement cup 2 is assemblied on main frame 1 by described boss 11 is driven and on move, and after main frame 1 and diatery supplement cup 2 are thrown off, to be resetted by the first counter pushing away of spring 6.
If limiting bracket 8 is in the centrifugal side of its impulse stroke, now limiting bracket 8 is positioned on the path that gangbar 4 upwards advances, thus when limiting bracket 8 is positioned at the centrifugal side of its impulse stroke, gangbar 4 upper end is restrained and cannot be up, in other words, with this understanding, that diatery supplement cup 2 can not be correct because of the interference of gangbar 4 or be assemblied in reliably on main frame 1.
See limiting bracket 8 again, be its configuration driven and reset two-part structure, its initial position is in the centrifugal side of its impulse stroke, the second spring 7 is used to ensure, under the condition not adopting such as the second spring 7, also can adopt other elastomeric elements, or directly adopt hand-reset.Of equal value mutually, foregoing first spring 6 also can not be arranged, and gangbar 4 resets based on self gravitation.
In a first embodiment, the impulse stroke of limiting bracket 8 is at diatery supplement bowl cover 3 stroke in the radial direction, in certain embodiments, the trip can also be the tangential stroke of diatery supplement bowl cover 3, driven by diatery supplement bowl cover 3 rotates, therefore, such as pinion and rack can be adopted to realize rotating the conversion with rectilinear motion.Moving direction by limiting bracket 8 be configured to the tangential of diatery supplement bowl cover 3 or with a certain direction tangentially paralleled, limiting bracket 8 is partly configured tooth bar, diatery supplement bowl cover 3 is arranged the operative gear (also known as sector gear) be meshed with tooth bar, with this understanding, its reset does not need extra reset components, only needs rotating backward of diatery supplement bowl cover 3 that limiting bracket 8 just can be driven to do centripetal motion.
In further embodiments, diatery supplement bowl cover 3 does the action of upper and lower lid, can adopt Wedge mechanism to realize motion conversion, convert the horizontal movement of limiting bracket 8 to by moving up and down of diatery supplement bowl cover 3 based on this.
Wedge mechanism is a kind of common mechanism of mechanical field, be by wedge and slide block with the use of, become the mechanical mechanism moved both vertically as horizontal movement or banking motion.Adaptably, limiting bracket 8 construct in Wedge mechanism for slide block, and on diatery supplement cup handle 21, construct one be again vertically oriented and the wedge with upwards reset function.Here reset function generally also adopts spring to realize.
Known based on said structure, namely the inclined-plane of wedge is configured to the inclined-plane in corresponding profile drive division.
Interlock be unable to do without lock section, and wherein aforesaid limiting bracket 8 forms a class lock, for ensureing that diatery supplement cup 2 can not be contained on main frame 1 when diatery supplement bowl cover 3 does not cover when centrifugal side to the constraint of gangbar 4.Another kind of lock is then for ensureing that diatery supplement bowl cover 3 can not be removed when diatery supplement cup 2 is contained on main frame.
What another kind of lock realized is is rotating diatery supplement bowl cover 3 in order to can retrain the rotation of diatery supplement bowl cover 3 in first embodiment of taking off, by move up and down take off diatery supplement bowl cover 3 the second embodiment in then should retrain moving up and down of diatery supplement bowl cover 3.
In a first embodiment, when gangbar 4 is positioned at up stop, should directly coordinate to be formed with diatery supplement bowl cover 3 and retrain, this kind coordinates on the one hand because gangbar 4 is configured to bar part, be easy to form plug structure, realized the constraint that diatery supplement bowl cover 3 is rotated by upper and lower plug structure, be analogous to latch.
In certain embodiments, the upper end of gangbar 4 can be configured to backing pin, and the upper end of gangbar 4 or accessory structure are positioned at diatery supplement bowl cover 3 and rotate on the path of backhaul when it is positioned at up stop, forms the constraint of backing pin realization to diatery supplement bowl cover 3.
If diatery supplement bowl cover 3 is descending forms of motion, i.e. situation in aforesaid second embodiment, because gangbar 4 also moves up and down, with this understanding, need attachedly to join the locking of other structures for diatery supplement bowl cover 3, such as aforesaid Wedge mechanism, wedge is configured in gangbar 4, corresponding slide block is arranged on diatery supplement cup handle 21, and slide block forms latch, and diatery supplement bowl cover arranges pin hole.
Based on description above, the basic comprising of interlocking mechanism is more clearly, if its general principle is diatery supplement bowl cover 3 when not covering on diatery supplement cup 2, due to the constraint (being also analogous to backing pin) of limiting bracket 8, gangbar 4 cannot be up, and can not correctly be arranged on main frame 1; And if bowl cover 3 puts in place, then the centripetal motion of limiting bracket 8 puts in place, relieves the upper row constraint to gangbar 4, and allows diatery supplement cup 2 to be installed on main frame 1; Up simultaneously due to gangbar 4, the upper end of gangbar 4 defines constraint to diatery supplement bowl cover 3 again, and it can not be thrown off.Based on this, effectively overcome the uncorrelated defect of diatery supplement bowl cover 3 and main frame 1 in background technology, and therefore make its safety in utilization greatly improve.
In the illustrative structure of Fig. 1-Fig. 7, described limiting bracket 8 and gangbar 4 are as driven member, again as lock section bearing part, associated main frame 1 is provided with boss (the actual wedge component forming Wedge mechanism) 1, associated diatery supplement bowl cover 3 is then provided with push pedal 32 (the actual wedge component forming Wedge mechanism), and these components form slide block and the wedge of Wedge mechanism.Intersecting again based on gangbar 4 and limiting bracket 8 impulse stroke, and the constraint of gangbar 4 top dead centre state to push rod 32 realizes the interlocking mechanism of safe food-processing machine, thus realize main frame 1 and diatery supplement bowl cover 3 associate and based on the locking of above-mentioned principle and lock-off, to realize the object of use safety.
Should be appreciated that in the present invention, give normally to assemble and the interlocking of realization also can by artificial interference, such as, do not cover diatery supplement bowl cover 3, artificial promote limiting bracket 8 and remove the constraint up to gangbar 4, but this kind of artificial access does not represent the forfeiture of above-mentioned interlock.
About gangbar 4, himself structure and replaceable structure, its restraining structure, guide frame, its resetting structure is specific as follows:
First, as previously mentioned, the main body of gangbar 4 is bar parts, in the structure shown in Fig. 1 and Fig. 2, it contains with the holding cavity structure upper and lower two ends of diatery supplement cup handle 21 structure in other words, the structure extended in the horizontal direction, and this structure does not affect its motion as the component that moves up and down.
Should be appreciated that locking the stroke generally all depending on some component with lock-off realizes, but do not represent that required stroke is large especially.As previously mentioned, diatery supplement cup handle is the comfortable of satisfied grasping, and its section is relatively large.Understandable, the power of gangbar 4 transmission does not need too large, based on the design of rational mechanics about frame for movement, its section can be relatively little, with this understanding, the space of cavity volume meets under the condition holding gangbar 4, and still possess certain space nargin, this nargin can meet the setting of its impulse stroke.
For satisfied grasping, diatery supplement cup handle 21 is generally ear type structure, namely containing vertical portion, also containing horizontal component or vertically to the part of horizontal transition or inclination, structure such as shown in Fig. 2, this structure can not produce the restriction to impulse stroke or the too much interference to movable piece in the application that impulse stroke is little.
