The specific embodiment
As shown in Figure 1, this casing two-way door-opening mechanism includes casing 1 and chamber door 8.As shown in Figure 1 and Figure 2, this casing two-way door-opening mechanism is connected with hinge wheel 11 at four edges of casing 1 front end, the chamber door end of hinge wheel 11 has the groove 17 of bar shaped, shown in Fig. 4,5,6, groove 17 is swallow-tail form and connects hinge wheel 11 in the horizontal direction at vertical plane, and is narrow at the wide other end of horizontal plane upper groove 17 1 ends.Shown in Fig. 2, Fig. 4,5,6, on each hinge wheel 11, all have a circle deep-slotted chip breaker 12, each hinge wheel 11 is all to having by holding out against the ball 14 of spring 15 apical graftings at deep-slotted chip breaker 12; Deep-slotted chip breaker 12 places of 14 apical graftings of ball have the hole of bead 16 of matching with ball when projection 10 embeds the groove 17 of hinge wheels 11, the purpose that the hole of bead 14 is set is when the door of its side is opened, hinge wheel 11 is in the position that groove 17 matches with projection 10, so that chamber door is when closing, projection 10 can embed in the groove 17 smoothly.When ball 14 headed into the hole of bead 16, horizontal plane upper groove 17 narrow ends (rushed at casing) inwards.
Shown in Fig. 1,2 and 3, this casing two-way door-opening mechanism all is fixed with the projection 10 of the bar shaped that can embed groove 17 in the position of chamber door 8 relative each hinge wheel, as shown in Figure 3, projection 10 is in the outside wide inwardly narrow structure of vertical plane for matching with the groove 17 of swallow-tail form, the cross section of groove 17 is a herringbone, can make the active force of chamber door 8 tenesmus of 10 preventions of 17 pairs of projections of groove and projection 10 one like this, the weight that prevents chamber door 8 all is pressed on the hinge wheel 11 of bottom, and it is convenient that chamber door 8 is opened; Match with groove at horizontal plane upper protruding block 10, promptly rush at the width of the width of chamber door one end, can make projection 10 can pass in and out groove more smoothly like this less than the other end.All be penetrated with the hinge 4 that projection 10 relatively moves up and down at the middle part of each projection 10.As shown in Figure 3, the upper semisection of hinge 4 is cylindrical, and lower semisection is a strip, and the top of hinge 4 is the inclined-plane, and the inclined-plane can enter groove 17 and hinge axis hole 18 over against the direction of casing so that stretch out the hinge 4 of projection 10 under the effect of extruding force.Middle part at the lower semisection of hinge 4 is provided with the limiting plate 9 that is fixed on the chamber door, and limiting plate 9 is used to prevent that hinge 4 from rotating so that the inclined-plane on hinge 4 tops when closing chamber door over against the direction of casing.Shown in Fig. 2,4, on each groove 17, all have the hinge axis hole 18 that matches with hinge 4, being provided with on hinge 4 can be with the spring 13 of hinge 4 tops to hinge axis hole 18.
As shown in Figure 1, this casing two-way door-opening mechanism all is connected with handle 2 in the and arranged on left and right sides of chamber door 8, all is connected with switch block 3 on each handle 2, and switch block 3 can be cylindrical, square column type or triangle cylindricality etc.Each hinge 4 is connected with the switch block 3 of homonymy by line 5, and the line that wherein connects the hinge of upper end passes the fixed pulley 6 of switching on chamber door and is connected with the switch block tension of homonymy; The line that connects the hinge of lower end can directly be connected with the switch block tension of homonymy, also can be connected with the switch block tension by pulley 7 backs.
This casing two-way door-opening mechanism is when wherein a side is opened, pull the handle 2 of this side with hand, handle 2 drives switch block 3 and rotates, the switch block 3 that rotates twines line 5 thereon, thereby the hinge that drives this upper lateral part moves down, the hinge of bottom moves up, hinge 4 is broken away from hinge axis hole 18, and outwards pull handle 2 is about to chamber door 8 and opens from this side.In opening procedure, the hinge of opposite side stretches in hinge axis hole, and projection and hinge wheel are fixed, and the chamber door that rotates simultaneously drives projection and rotates, and it is that rotate at the center with the wheel shaft of upper and lower two hinge wheels that projection drives the hinge wheel that is coupling on casing.When this casing two-way door-opening mechanism is closed, chamber door 8 is promoted to casing 1 direction, under thrust and the effect to the extruding force on the inclined-plane on hinge 4 tops, the hinge of upper end moves down, move on the hinge of lower end, and projection 10 is embedded in the groove 17 of hinge wheel 11 smoothly; After projection 10 entered groove 17, hinge 4 entered in the hinge axis hole 18 under the effect of spring 13, thereby with chamber door 8 and casing 1 closure.
