Embodiment
As shown in Figure 1, the utility model is that example describes with JN43-80 type cokery.Fire door knife-edge positioning adjustment device of the present utility model is that knife-edge 7 is fixed on the side of web 8, and this web 8 is forms of welding with the fixed form of knife-edge 7, and this web 8 is fixed on the inboard of knife-edge 7 to realize sealing effectiveness.The opposite side bending of web 8 is fixed on the oven door body 9, and this fixed form presses the frame backing plate with the fixture block card on the web 8 with on a draw-in groove 10 of oven door body 9 with knife-edge.Above-mentioned knife-edge 7 is the Closed loops around oven door body 9, and web 8 also is a Closed loop around oven door body 9.
For making above-mentioned knife-edge 7 have sealing effectiveness, can realize the adjustment of knife-edge 7 sealed states simultaneously, the utility model also is provided with knife-edge elasticity positioning adjustment device in the rear end of knife-edge 7.This elasticity positioning adjustment device is to press frame 4 to be fixed on the oven door body 9 knife-edge, and it is that circular cylinder body and rectangle steel plate are welded that this knife-edge is pressed frame 4, and its axis direction is vertical with fire door edge line cloth set direction.
As shown in Figure 1 and Figure 2, this knife-edge presses the inside of frame 4 to be provided with spring assembly, and this spring assembly comprises spring 12, spring link 1, spring backing plate 13 and spring tamponade 3.Wherein spring link 1 is axially disposed within the inside that this knife-edge is pressed frame 4, and spring 12 is set on this spring link 1, and the front end of this spring link 1 is provided with a knife-edge draw-in groove 6, and this knife-edge draw-in groove 6 is used to fix the rear end of knife-edge 7.In addition, also be provided with a boss in the front portion of spring link 1, on this boss against an annular spring backing plate 13, the preceding end in contact of this spring backing plate 13 and spring 12, this spring backing plate 13 can push draw-in groove 6 by boss, makes draw-in groove 6 pushing knife-edges 7 hold out against firedoor frame.
The rear portion of this spring link 1 and knife-edge are pressed an also sheathed spring tamponade 3 between the frame, and the forebody of this spring tamponade 3 is annulars, the back end in contact of its front end and spring 12, and on this outer rim, be provided with outside screw; And the latter half of outer rim with outer-hexagonal shape of this spring tamponade 3 can be rotated (as shown in Figure 3) this outer rim with common wrench.Simultaneously knife-edge press frame 4 the rear portion be provided with the internal thread that cooperates with the outside screw of spring tamponade 3 so that this spring tamponade 3 screws togather in spring pressure frame 4.
The rear portion of this spring link 1 is provided with outside screw, and a set nut 2 is set on this outside screw.This set nut 2 is screwed on this spring link 1.
Above-mentioned the utility model at first connects a face down bonding of knife-edge 7 and web 8 fixingly in use, and the opposite side of web 8 is fixed on the oven door body 9.And then with the rear end of 6 fixings of the knife-edge draw-in groove on the spring link 1 at knife-edge 7, screw spring tamponade 3 from the rear portion, make the front end of this spring tamponade 3 hold out against spring 12, the front end of spring 12 holds out against spring bearer plate 13, thereby makes draw-in groove 6 hold out against the rear end of knife-edge 7 and form certain stress.At this moment tighten set nut 2 from the rear portion of spring link 1 again, make the axial location of spring link 1 elastic fixing, in this state, it is Elastic Contact that the rear portion of knife-edge 7 and spring are pressed between the frame 4.Therefore, when fire door was closed, the front end of knife-edge 7 and the contact condition of firedoor frame also were Elastic Contact.So knife-edge 7 of the present utility model can have better closed state.And when adjusting, also be after having adjusted spring tamponade 3, to have tightened set nut 2 more just can.
