Example one

This embodiment is substantially as shown in fig. 1: the utility model provides an angle adjustable's pipe of discharging fume, includes bellows 10 and bellmouth 20, and in this embodiment, bellmouth 20 passes through staple bolt fixed mounting on one end of bellows 10, and the other end of bellows 10 can lead to the fan of discharging fume of factory building, also can connect the exhaust fan that can smoke and exhaust air. Fixedly connected with connecting portion that can buckle at will on horn mouth 20, connecting portion are used for hanging horn mouth 20 in the top of BGA rework platform. In this embodiment, the connecting portion is the gooseneck 30 that can remain fixed after buckling, and the upper end of gooseneck 30 is fixable installs on the roof of factory building. In this scheme, set up horn mouth 20 and effectively enlarged the area in suction opening, make that the exhaust fume can be better by the pump removal. The gooseneck 30 with certain rigidity and capable of being bent is selected as a connecting part, the angle and the height of the bell mouth 20 can be adjusted by changing the shape of the gooseneck 30, and the gooseneck is economical and practical and is convenient to operate.

Example two

The utility model provides an angle adjustable's exhaust pipe, includes bellows 10 and bellmouth 20, and in this embodiment, bellmouth 20 passes through staple bolt fixed mounting in the one end of bellows 10, and the other end of bellows 10 can access to the fan of discharging fume of factory building, also can connect the exhaust fan that can smoke and exhaust air. Fixedly connected with can be at will the connecting portion of buckling on the horn mouth 20, and connecting portion are used for hanging horn mouth 20 in the top of BGA rework platform. As shown in fig. 2 and 3, the connecting portion includes a telescopic rod and a rotating rod 70, and one end of the rotating rod 70 is fixedly installed on the bell mouth 20. The telescopic rod comprises a fixed rod 40 and a cylindrical sliding rod 50, a sliding cavity, a strip-shaped groove 41 and a plurality of clamping grooves 42 which are uniformly distributed along the length direction of the strip-shaped groove 41 are formed in the fixed rod 40, and the clamping grooves 42 are in a 7 shape; the strip-shaped groove 41 and the clamping groove 42 are both communicated with the sliding cavity, and the strip-shaped groove 41 is communicated with the clamping groove 42. The upper part of the sliding rod 50 is connected in a sliding cavity in a sliding mode, a clamping strip 51 connected on the strip-shaped groove 41 in a sliding mode is welded on the sliding rod 50, and the clamping strip 51 can be clamped on the clamping groove 42 in a clamping mode. A ball joint 60 is fixed to the lower end of the sliding rod 50, and a ball head 71 rotatably connected to the ball joint 60 is fixed to an end of the rotating rod 70 away from the bell mouth 20, and the ball head 71 can rotate in all directions in the ball joint 60. The ball joint 60 is provided with a fixing portion for fixing the ball head 71, and in this embodiment, the fixing portion is a bolt 61 screwed on the ball joint 60, and one end of the bolt 61 can contact with the ball head 71.

The position of adjustable horn mouth 20 through the length of adjusting the telescopic link, when needs make horn mouth 20 move down some height, rotate slide bar 50, make card strip 51 remove from draw-in groove 42 on bar groove 41, then slide bar 50 slides down, when the position regulation of slide bar 50 arrives suitable position, rotate slide bar 50 again, make card strip 51 block on near draw-in groove 42, the length of telescopic link is prolonged this moment, the position of horn mouth 20 also obtains adjusting. When the bell mouth 20 needs to be moved up by some height, the specific operation manner is similar, and the detailed description is omitted here. This scheme sets up the telescopic link and can adjust the height of horn mouth 20 according to actual conditions, makes it more be suitable for the actual production needs. The rotating rod 70, the ball joint 60 and the ball head 71 are arranged, and the ball head 71 can rotate in all directions in the ball joint 60 so as to adjust the position of the rotating rod 70, and finally the bell mouth 20 can be located at a proper position. After the position of the bell 20 is adjusted, the bolt 61 is screwed, so that one end of the bolt 61 is tightly pressed against the surface of the ball head 71, and at this time, because of the large friction force between the ball head 71 and the bolt 61 and between the ball head 71 and the ball joint 60, the ball head 71 cannot rotate, and the position of the rotating rod 70 can be well fixed.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the schemes is not described herein. It should be pointed out that, for the person skilled in the art, without departing from the structure of the invention, a number of variants and improvements can be made, which should also be regarded as the scope of protection of the invention, which will not affect the effect of the implementation of the invention and the utility of the invention.
