Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Shown in Fig. 2 and Fig. 6, an aspect as the utility model provides a kind of otic placode 10; This otic placode 10 comprises the body 11 with the first end 11a and second end 11b; The first end 11a is used for linking to each other with basic part 20, and the said second end 11b is used for linking to each other with movement parts 30, wherein; Otic placode 10 also comprises first joint 12 that is arranged on the said first end 11a, and this first joint is that cross section is non-circular boss or groove.
The first end 11a of otic placode 10 is connected mutually with basic part 20; As another aspect of the utility model, the basic part 20 that provides a kind of and above-mentioned otic placode to link to each other is shown in Fig. 3 and Fig. 5; This basic part 20 has and is used for the surface that is connected that links to each other with otic placode 10; Wherein, be formed with second joint 21 on this connection surface, this second joint is that cross section is non-circular groove or boss.
Because otic placode 10 is connected mutually with basic part 20, therefore, first joint 12 on the otic placode 10 forms the shape that matches each other with second joint 21 on the basic part 20.
According to first kind of mode of execution of the utility model, like Fig. 2, first joint 12 is non-circular boss for cross section, and second joint 21 then as shown in Figure 3 should be the non-circular groove that is complementary with first joint 12.
Be connected the power that the movement parts 30 of the second end 11b of otic placode 10 is applied on the otic placode 10 and be passed to first joint 12.Because first joint 12 is non-circular, therefore can in second joint 21, not rotate.Therefore; First joint 12 has almost born the whole power from movement parts 30; Bolt in the fastening piece 40 receives shearing force hardly, only needs vertical direction shown in the figure that otic placode 10 and basic part 20 are fastenedly connected and gets final product, thereby reduced the risk that the bolt in the fastening piece 40 is cut off.
In first kind of mode of execution of otic placode 10, first joint 12 can be integrally formed with otic placode 10.For example, the structure that forms as one of the body 11 through mode such as casting, welding and otic placode 10, thus improve the structural strength of otic placode 10, and bear bigger shearing force.
Second kind of mode of execution according to the utility model; As shown in Figure 5; Second joint 21 on the basic part 20 is non-circular boss for cross section; Then as shown in Figure 6, first joint 12 on the otic placode 10 is the groove (shown in Fig. 6 is the thin situation of otic placode, and groove runs through otic placode 10 along thickness direction) that the cross section and second joint 21 are complementary.
Likewise, second joint 21 can pass through various ways such as welding, casting and basic part 20 to be connected the surface one-body molded, thereby improve the intensity of basic part 20, and bear bigger shearing force.
Said non-circular can be multiple shape such as oval, quincunx, as long as can make win joint 12 with can not relatively rotate after second joint 21 is connected mutually.For the ease of processing, preferably, the cross section of first joint 12 is a polygonal.Correspondingly, the cross section of second joint 21 is the polygonals that are complementary with first joint 12.For example, the cross section of first joint 12 and second joint 21 is quadrilateral, pentagon or Hexagon etc.
For the ease of realizing that further preferably, as shown in Figure 2, the cross section of first joint 12 is a square, identical ground, the cross section of second joint 21 also are squares.
The third mode of execution as the utility model; Said otic placode linkage structure can also comprise otic placode 10, basic part 20, link and fastening piece 40; Wherein, otic placode 10 is the above-mentioned otic placode that the utility model provided, and basic part 20 is the above-mentioned basic part 20 that the utility model provided; Otic placode 10 and basic part 20 be through being connected with the said link of first joint 12 with second joint, 21 form fit respectively, and fastening through fastening piece 40.
In the third mode of execution, first joint 12 of otic placode 10 can can be non-circular groove for cross section also simultaneously for cross section is non-circular boss with second joint 21 on the basic part 20 simultaneously.The shape at said link two ends is complementary with first joint 12 and second joint 21 respectively.Through said link with first joint 12 with after second joint 21 is connected mutually; Can prevent equally to produce between second joint 21 of first joint 12 and basic part 20 of otic placode 10 relative to rotate, thereby prevent that the bolt in the fastening piece 40 from receiving shearing force.
For the ease of processing, preferably, first joint 12 is identical with the shape of cross section of second joint 21, and this moment, said link was the coupling shaft that cooperates with said groove shapes, perhaps was the connecting sleeve with said boss form fit.
In the third mode of execution of the utility model, the shape of cross section of first joint 12 and second joint 21 also can be inequality.One end of said link cooperates with said groove shapes, the other end and said boss form fit.In this kind situation, first joint 12 both can the time boss also can be groove, second joint 21 both can be that boss also can be a groove, as long as the cross section of first joint 12 and second joint 21 is non-circular.End through said link cooperates with first joint 12, the other end cooperate with second joint 21 can prevent between first joint 12 and second joint 21 to produce relative to rotate, thereby prevent that the bolt in the fastening piece 40 from receiving shearing force.
Through being after non-circular first joint and non-circular second joint that is being provided with on the basic part are worked in coordination at the cross section that is provided with on the otic placode; First joint or second joint can bear the shearing force from movement parts; Thereby make fastening piece not receive shearing force, and therefore reduced the impaired probability of fastening piece.
Need to prove that in addition each the concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
