For the present invention aforementioned and other technology contents, feature and effect, in following cooperation refer to the attached drawing are preferable In the detailed description of embodiment, clearly can present.The direction term being previously mentioned in following examples, for example:Upper and lower, left, It is right, front or rear etc., only it is the direction with reference to appended accompanying drawing.Therefore, the direction term for using is for illustrating not for limiting The present invention.
Fig. 2 and Fig. 3 is referred to, the bellmouth measuring equipment 100 of the present embodiment mainly includes a dial drum 110, proficiency Rotating cylinder 120, a connecting rod 130, a bonnet 140, multiple measurement bars 150, multiple first latches 160 and multiple second latches 170.
Dial drum 110 has one first scale mark 111 and one first external thread part 112.
Handss rotating cylinder 120 is sheathed on dial drum 110 in a rotating manner.For more detailed, as shown in Figure 2, Figure 3 and Figure 4 Shown, handss rotating cylinder 120 has in one first internal thread part 121, one second internal thread part 122, one second scale mark 123, Flange 124 and multiple anti-slip tanks 125.Here, the first internal thread part 121 of handss rotating cylinder 120 is be engaged in dial drum 110 One external thread part 112, thus the rotating cylinder 120 that can make to go smoothly is sheathed on dial drum 110 in a rotating manner.Additionally, such as Fig. 2 institutes Show, when handss rotating cylinder 120 is sheathed on dial drum 110 in a rotating manner, handss rotating cylinder 120 slides on the of dial drum 110 On one scale mark 111, and the second scale mark 123 of handss rotating cylinder 120 is corresponding to the first scale mark of dial drum 110 111.In addition, among the present embodiment, among inward flange 124 takes shape in the inside of handss rotating cylinder 120, and inward flange 124 is located at Between first internal thread part 121 and the second internal thread part 122.Additionally, anti-slip tank 125 is taken shape on the outside of handss rotating cylinder 120, its Can be used to appropriate friction effect is provided in rotating operation.
As shown in figure 4, among connecting rod 130 is arranged in dial drum 110 and handss rotating cylinder 120, and connecting rod 130 has one First end 131 and a second end 132.Here, first end 131 is relative to the second end 132, and first end 131 Protrude from one end of dial drum 110.Additionally, the second end 132 is connected to the inward flange 124 in handss rotating cylinder 120.
Shown as shown in Figure 2, Figure 3 and Figure 4, bonnet 140 is connected to handss rotating cylinder 120, and bonnet 140 has one second external screw thread Portion 141.Here, as shown in figure 4, the second internal thread part 122 of handss rotating cylinder 120 is the second external screw thread for being engaged in bonnet 140 Portion 141.Furthermore it is noted that when bonnet 140 is connected to handss rotating cylinder 120, the second end 132 of connecting rod 130 is It is connected between the inward flange 124 in handss rotating cylinder 120 and bonnet 140.
As shown in Figures 2 and 4, multiple bars 150 that measure are connected to dial drum 110 in a symmetrical manner with connecting rod 130 Between first end 131.Here, each measure bar 150 have a turning end 151, a sliding end 152, a long open-work 153 and One tapered portion 154.Turning end 151 is relative to sliding end 152, and turning end 151 is connected to connecting rod 130 in a rotating manner First end 131.Sliding end 152 is connected to dial drum 110 in a sliding manner.Long open-work 153 take shape in sliding end 152 it On.More specifically, each first latch 160 is arranged in the turning end 151 and connecting rod 130 that each measures bar 150 First end 131 among, consequently, it is possible to each measure articles 150 turning end 151 can be relative to the of connecting rod 130 One end 131 is rotated.On the other hand, each second latch 170 be arranged in each measure bar 150 long open-work 153 and Among dial drum 110, consequently, it is possible to each sliding end 152 for measuring bar 150 can slide relative to dial drum 110(Also That is, among the second latch 170 slides on long open-work 153).Additionally, tapered portion 154 take shape in turning end 151 and sliding end 152 it Between.
As described above, when handss rotating cylinder 120 is rotated relative to dial drum 110, handss rotating cylinder 120 will order about connecting rod 130 Move relative to dial drum 110(Because the second end 132 of connecting rod 130 be connected to the inward flange 124 in handss rotating cylinder 120 with Between bonnet 140), thus each can be forced to measure bar 150 and rotated and phase relative to the first end 131 of connecting rod 130 For dial drum 110 slides.
Next explanation measures the function mode of the Angular Dimension of a bellmouth with bellmouth measuring equipment 100.
First, as shown in figure 5, by bellmouth measuring equipment 100 alignment be inserted into a bellmouth T among.Then, such as Fig. 6 Shown, the tapered portion 154 of multiple measurement bars 150 of bellmouth measuring equipment 100 first can preliminarily be connected to the interior of bellmouth T Wall.Now, measure bar 150 to be located under an original state.Here, L represents the vertical dimension of the second latch 170 to connecting rod 130, X1 represents the horizontal range of 160 to the second latch 170 of the first latch, and θ 1 is represented and measured between bar 150 and connecting rod 130 Angle.Here, L, X1 and θ 1 are known numerical value.
Then, as shown in fig. 7, handss rotating cylinder 120 can be rotated relative to dial drum 110 and order about connecting rod 130 relative to quarter Degree cylinder 110 is moved, till the tapered portion 154 that must measure bar 150 fits in the inwall of bellmouth T completely.Now, first insert The horizontal range of 160 to the second latch 170 of pin has turned into X2, and the angle measured between bar 150 and connecting rod 130 has turned into θ2.Here, θ 2 is also the angle between the inwall and connecting rod 130 of bellmouth T.Meanwhile, as shown in figure 8, the first latch 160 to The movement value of the horizontal range of the second latch 170 is by represented by Δ.Here, the numerical value of Δ can be by handss rotating cylinder 120 in dial drum Mobile numerical value on 110 the first scale mark 111 and learn(That is, by the first scale mark of accurate measurement 111 and second Scale mark 123 is learnt with respect to change).Then, following relational expression can be obtained according to trigonometric function relation:
Tanθ2=L/X2=L/(X1-Δ).
That is, θ 2=arcTan(L/(X1-Δ)).
As L, X1 are that known numerical value and Δ can also be measured via the first scale mark 111 of dial drum 110 Learn, therefore the numerical value of θ 2 just can be via θ 2=arcTan(L/(X1-Δ))Relational expression and obtain.Finally, due to bellmouth T Angle be that both sides are symmetrical, therefore the Angular Dimension of bellmouth T be twice θ 2(That is, 2 × θ 2).
As described above, by bellmouth measuring equipment 100 disclosed in this invention, the Angular Dimension of any bellmouth Easily with it is accurately obtained, thus time and the cost of product manufacturing can be greatly reduced.
Although the present invention is disclosed in preferred embodiment, but which is not limited to the present invention, any this area Technical staff, without departing from the spirit and scope of the present invention in the case of, should make a little change with retouching, therefore Protection scope of the present invention should be defined depending on the defined person of the scope of appending claims.
