Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in fig. 1: the exhaust system hanger positioning mechanism comprises a hanger positioning block 1, a positioning pin 2, a positioning piece 3 and a spring 4. The pendant positioning block 1 is provided with a positioning hole 1.1 which penetrates through the top surface and the positioning surface. The positioning pin 2 comprises an end part 2.1, a positioning rod and a positioning head 2.5; the positioning head 2.5 and one end of the positioning rod close to the positioning head 2.5 are inserted into the positioning hole 1.1 from the top surface of the positioning block 1, and the positioning head 2.5 can penetrate through the positioning hole 1.1 and extend out of the positioning surface; the middle part of locating lever is equipped with spacing groove 2.3, and spacing groove 2.3 divide into the locating lever and be close to tip 2.1 first gag lever post 2.2 and be close to locating head 2.5's second locating lever 2.4, and the one end that second locating lever 2.4 is close to spacing groove 2.3 is equipped with breach 2.6. The positioning piece 3 is arranged on the side wall of the pendant positioning block 1, and the inner end of the positioning piece 3 extends into the positioning hole 1.1 and clamps the notch 2.6 or the limiting groove 2.3. The spring 4 is sleeved outside the positioning rod and is positioned between the pendant positioning block 1 and the end part 2.1 of the positioning pin 2.
Specifically, the positioning member 3 may be a jack screw. As shown in fig. 2, the limiting groove 2.3 is an annular limiting groove, and the tangent plane of the notch 2.6 is tangent to the circumferential surface of the limiting groove 2.3, so that the positioning pin 2 can conveniently rotate and withdraw. As shown in fig. 3, a magnet 5 is installed on the positioning surface of the pendant positioning block 1 to facilitate the absorption of the pendant 6.
