Embodiment
The utility model unitary construction with at the round and smooth open-and-close mechanism of a kind of multiple tooth shaft staggered connection-rod linkage type of prior art
(see Fig. 3)almost identical, only just to prior art pitch wheel gear teeth partial structurtes wherein
(see Fig. 2)improve, obviously, improve the part related to and limit to very much, clearly, implement very simple, therefore a lot of content need not repeat structure
(because both most parts are all identical, overall structure is too close, thus note that in accompanying drawing separately do not draw separately shape as shown in Figure 3 but be overall structure axonometric drawing of the present utility model), only select its general condensed summary embodiment below:
see Fig. 1,improve the round and smooth open-and-close mechanism of the multiple tooth shaft staggered connection-rod linkage type of one that the gear teeth are spacing, comprise the first pivot 11, the 4th pivot 14, individual gears 20, connecting rod Double-gear 30, gear tooth, it is characterized in that, the distribution of mutually engageable gear tooth is provided with, in addition then without intermeshing described gear tooth distribution in the relative rotation angle that at least any pair intermeshing described gear tooth is only given between
(are all also the requirements of prior art content to this, please emphasis be see Fig. 2 simultaneously, obviously it has made it cannot continue engagement and spacing when continuing rotation rearward, but also obviously, the accurate and stable repeatability of spacing angle is all not bery reliable)and engage each other for a pair that now enters end of engagement described gear tooth other be provided with two mutual against support surface 50
(this is the improvement being different from prior art aspect, namely prior art be at this moment be in follow-up without the gear teeth, and though improvement is also without the gear teeth afterwards, but really there occurs change without the shape at gear teeth place, also namely described in a pair of originally now entering end of engagement the engagement of gear tooth stop spacing angular position to gear tooth described in this pair other near the connected position shape without the gear teeth change forming surface 51 respectively into and support on face 52, namely spacing intensity and precision are improved, see Fig. 1 to face in face), for strengthening gear point limit strength and the precision of mutual spline.Normally
generallydisplay device
the spacing angle of rotation has two places, and (in Fig. 1, the left and right place gear tooth of the first half is equipped with the spacing angle of a rotation, the left and right place gear tooth of Lower Half is equipped with the spacing angle of another rotation, obviously, because of the interlock effect of whole mechanism, also can be found out by Fig. 1, even if only have a left side half or the right side partly can realize the spacing angle of two rotations too)consider angular orientation sensitivity change and stressed less more favourable, implement the described support surface 50 of different amount between general described individual gears 20 preferably respectively on described first pivot 11 and on described 4th pivot 14 and the described connecting rod Double-gear 30 liang of engaging gear gear teeth be meshed, more conveniently particularly can meet two spacing angle requirement more accurately
(gear teeth transmission between certain connecting rod individual gears and connecting rod individual gears also can be implemented spacing, but precision is compared low, because structure is very similar, implement very similar, therefore the engagement gear teeth other enforcement gear point not also separately being presented at connecting rod individual gears engagement connecting rod individual gears in figure is spacing, does not repeat).
Further, described support surface 50 can be plane
(obviously, described support surface 50 also can be the face of other shape, and what face 51 described in Fig. 1 and face 52 just all adopted is plane, obviously can not necessarily non-plane, but generally for the sake of simplicity, plane).
Further, the maximum and minimum concentric containing circular arc inner area that described support surface 50 is allowing is maximum
(this considers from whole open-and-close mechanism profile, obviously, the normal condition support surface 50 larger intensity of area is relative with precision better, but the thickness everywhere of bending folding means flex is generally all defined a uniform thickness value, therefore corresponding described support surface 50 area must allow in thickness in whole open-and-close mechanism bending range, also the same intracardiac and scope folded by external arc that the both sides namely at least not exceeding curved section thickness defined are formed, such guarantee curved section uniform thickness, without protruding, coated round and smooth to ensure the thickness both sides outward appearance of whole open-and-close mechanism, all the time uniform thickness, do not repeat, certainly, realize concentric inside and outside circular arc, so-called uniform thickness can only be approximate.As long as therefore allow, the maximum and minimum concentric containing circular arc inner area that described support surface 50 is allowing is as well maximum, to improve effective area of contact at stop surface place further, and then improves its intensity and precision further.
Described first pivot 11, described 4th pivot 14 are the adaptive non-circular hole of non-circular shaft with the coordinating of hole of the described individual gears 20 on it
(obviously, adopting section configuration to be the adaptive non-circular hole of non-circular shaft is the known actuation techniques that a kind of common assembly type realizes shaft member and the mutual synchronous axial system of orifice, therefore does not repeat, and this example adopts hole and the axle adaptation of kidney-shaped section), thus synchronous rotation transmit and share stressed
(like this, at described first pivot 11, described individual gears 20 on described 4th pivot 14, means of a powder metallurgy technique can be adopted easily integrally formed with the movable ear page connecting base with the movable ear page being connected display device respectively, when movable ear page is together with described individual gears 20 integrated synchronous rotation, drive described first pivot 11 or the synchronous rotation of described 4th pivot 14, described first pivot 11 or described 4th pivot 14 can continue synchronously to drive on it the synchronous rotation of individual gears 20 described in other again, if any words, and by described individual gears 20 by engagement driving connecting rod Double-gear 30, so just the power of movable ear page rotation is shared on the gear teeth of all gears meshing (certainly if any the gear teeth transmission also comprised between connecting rod individual gears and connecting rod individual gears, connecting rod individual gears is not shown) in figure, the described individual gears 20 avoiding described movable ear page to be connected and the described connecting rod Double-gear 30 be meshed with individual gears described in this 20 are born whole described movable ear page rotation power and are caused and stressedly excessively easily cause the described gear tooth on it to damage, and other individual gears 20 with engage other described in connecting rod Double-gear 30 and connecting rod individual gears stressed hardly with the connecting rod individual gears engagedunequal force phenomenon
).
The beneficial effects of the utility model are, when reaching the limit of gear point restraining position, end of engagement engage each other for a pair the gear teeth other be provided with two mutual against support surface 50, for strengthening gear point limit strength and the precision of mutual spline, namely spacing angular orientation has made a face backstop into, with described this, described gear tooth that may cause energetically that support surface 50 is born by continuing pressure rotation is damaged, greatly improve the anti-rotation strength capabilities of a pair gear tooth of final position engagement, be not easy broken teeth, and support surface, face is almost without any possibility of stepping down, spacing angular orientation is more accurate, final better, stronger, realize extreme angles limiting block point function more accurately.
In addition, described first pivot 11, described 4th pivot 14 are the adaptive non-circular hole of non-circular shaft with the coordinating of hole of the described individual gears 20 on it
,so just the power of movable ear page rotation is shared on the gear teeth of all gears meshing, the described individual gears 20 avoiding described movable ear page to be connected and the described connecting rod Double-gear 30 be meshed with individual gears described in this 20 are born whole described movable ear page rotation power and are caused and stressedly excessively cause the described gear tooth on it to damage, and other individual gears 20 with engage other described in connecting rod Double-gear 30 and the connecting rod individual gears unbalanced phenomena stressed hardly with the connecting rod individual gears engaged.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
