The design feature that is used for the foreplate hold down gag of slidingtype outlet guide device of the present utility model also is:
Described pressing plate is arranged on the end face of second sidewall of U-shaped guide and guard seat removably.
The end face of second sidewall of described U-shaped guide and guard seat is provided with screw, and pressing plate is provided with unthreaded hole, and the bearing pin of TOE screws in screw; Bearing pin is provided with waist through hole, and the length direction of waist through hole is consistent with the length direction of bearing pin, is provided with clapboard in the waist through hole.
The end face of second sidewall of described U-shaped guide and guard seat is provided with screw, and pressing plate is provided with through hole, and screw or bolt are anchored on pressing plate on the end face of second sidewall in the through hole of pressing plate screws in screw on the end face of second sidewall.
Compared with the prior art, the utility model beneficial effect is embodied in:
In the utility model, by wedge and pressing plate foreplate is anchored among the U-shaped guide and guard seat, contact for face between wedge and pressing plate and the foreplate, utilized the angle of friction characteristic on the inclined-plane of wedge, fastening reliability height, the anti-vibration performance is good, and foreplate is difficult for getting loose, the foreplate surface destruction that is difficult for being worn, the service life of having improved foreplate.Use the fastening mode of a plurality of screws to compare with prior art, the dismounting of wedge, pressing plate and quick and easy for installation has improved operating efficiency.During installation, foreplate is put into the middle depressed part of U-shaped guide and guard seat, a side of foreplate is close on the wall of U-shaped guide and guard seat sidewall, wedge shape space wedging wedge between the first side wall of the another side of foreplate and U-shaped guide and guard seat, then the screw on the end face of the through hole on the pressing plate and second sidewall of U-shaped guide and guard seat is aimed at, and got final product by bearing pin and clapboard combination, screw or bolting pressing plate.Foreplate hold down gag of the present utility model, fastening reliability height, the anti-vibration performance is good, and foreplate is difficult for getting loose, and has improved the service life of foreplate, and foreplate is removed with quick and easy for installation.
The utility model is particularly useful for slidingtype outlet guide device, is used for foreplate is anchored among the guide and guard seat.
