The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3.Fig. 1 is the front view that the present invention prepares open mode, and accompanying drawing 2 is vertical views that the present invention prepares open mode, and Fig. 3 is the left view that the present invention prepares open mode.Fig. 1, Fig. 2, Fig. 3 have provided the shape and the concrete structure of the embodiment of the invention, can be clear that the structure and the annexation of each part and assembly from Fig. 1, Fig. 2, Fig. 3.The present invention includes left and right door leaf 1, door hinge 2, be installed in wall seat 3 on the wall, be installed in the axle sleeve 5 on the right door leaf top edges, the swing handle 10 that is anchored on bolt axle 15, knocker 11, be installed in handle 10 below by pin 12 fixing bearing 13, catch 14, be installed in right door leaf 1 lower edge Upper shaft sleeve 16 and be installed in ground seat 17 on the floor 18.Upper/lower terminal at bolt axle 15 also is respectively arranged with eccentric wheel 3-1, these two eccentric wheel 3-1 are respectively with the last terminal 15-1 of bolt axle 15, be fastenedly connected with the lower end 15-2 of bolt axle 15, two eccentric wheel 3-1 be inserted in respectively wall seat 3, in the seat 17, two eccentric wheel 3-1 can rotate with the rotation of bolt axle 15; The middle and upper part of bolt axle 15 is provided with angle axle sleeve 7, angle sleeve block 8, and described angle axle sleeve 7 and bolt axle 15 are for being fastenedly connected; The middle part of left-hand door fan is by being provided with skewback 9 near the door hasp 1-1, and described skewback 9 matches with the bearing 13 that swing handle 10 is provided with below.
After installation of the present invention is achieved in that and earlier left and right door leaf 1 is installed by door hinge 2, assembly wall seat 3 on the wall above then of the right side of two door leaf hasp 1-1 again, and ground 17 is installed on the floor 18 of below; Wall seat 3, the hole 4 at seat four angles of 17 can fix with setscrew; Angle axle sleeve 7 is inserted in the position that bolt axle 15 is set, and angle axle sleeve 7 and 15 electric welding of bolt axle are fixed; Eccentric wheel 3-1 is inserted in terminal 15-1 on the bolt axle 15, lower end 15-2 respectively, eccentric wheel 3-1 and last terminal 15-1 and lower end 15-2 electricity consumption solid welding are fixed again; After then eccentric wheel 3-1 being inserted in wall seat 3 by the breach 3-2 on the wall seat 3, lower end 15-2 with bolt axle 15 is inserted in ground seat 17 again, choose suitable position along bolt axle 15 again and install axle sleeve 5, Lower shaft sleeve 16, angle sleeve block 8, can Upper shaft sleeve 5, Lower shaft sleeve 16, angle sleeve block 8 be fixed on the right door leaf with bolt when promptly installing, bolt axle 15 can rotate in Upper shaft sleeve 5, Lower shaft sleeve 16, angle sleeve block 8; Be welded one at the middle part of bolt axle 15 and have the swing handle 10 of knocker 11, bearing 13; Be provided with the angle sleeve block 8 that matches with angle axle sleeve 7 between Upper shaft sleeve 5 and the swing handle 10.
The present invention opens the door, closes door and is achieved in that when opening the door, (as Fig. 1, Fig. 2, shown in Figure 3) pulls swing handle 10 left, the angle axle sleeve 7 that is welded on bolt axle 15 also rotates with the rotation of bolt axle 15, and angle sleeve block 8 is fixed, with angle axle sleeve 7 jack-up upwards; When angle axle sleeve 7 upwards after the jack-up, the eccentric wheel 3-1 that is welded on bolt axle 15 two ends so is jack-up upwards thereupon also.When the bearing 13 of swing handle 10 went to skewback 9 positions, angle axle sleeve 7 was gone back the last summits that the end arrives angle sleeve blocks 8 at this moment, the handle 10 that continues to turn left, and jack-up again makes progress bolt axle 15.Eccentric wheel 3-1 also along with bolt axle 15 jack-up upwards, separates with ground seat 17, wall seat 3 respectively like this, when bearing 13 stops on skewback 9, holds catch 14 and is pulled outwardly, and bolt axle 15 upper ends is skidded off from the breach 3-2 of wall seat 3 door is opened.When closing (as Fig. 4, Fig. 5, shown in Figure 6), after holding the right door leaf 1 of catch 14 pushing and making bolt axle 15 tops enter breach 3-2, handle 10 turns right, the landing from the position that skewback 9 stops of bearing 13 this moment, eccentric wheel 3-1 and wall seat 3 when cause is opened the door, ground seat 17 all is the relaxation state of same position, at this moment eccentric wheel 3-1 is easy to be inserted in wall seat 3, in the ground seat 17, eccentric wheel 3-1 is inserted in wall seat 3, in the ground seat 17, again with turning handle 10 to right rotation, eccentric wheel 3-1 respectively with wall seat 3, ground seat 17 is in locking state gradually, utilize wall seat 3, the reaction force of ground seat 17, make bolt axle 15 compress right door leaf 1 gradually, by of the effect of right door leaf 1 with door hasp 1-1, gradually a left side, right door leaf 1 inwardly compresses, a left side, right door leaf 1 compresses the caulking gum 19 that is installed on the door again, heat-barrier material 20, thus reach good sealing effectiveness.When bolt axle 15 rotates to 180 to the right when spending, knocker 11 is buckled get final product.
