Detailed description of the invention
See shown in Fig. 1 to Fig. 3, the door body upper hinge that the present invention is used for fridge-freezer is described, this body upper hinge comprises: upper flap 3, hinge axis 4, first stiffener 1, wherein, one end of upper flap 3 is fixedly connected on the casing of fridge-freezer, the other end be extended with described hinge axis 4, first stiffener 1 be suspended to hinge axis 4 and with this hinge axis 4 matched in clearance.
See Fig. 3, hinge axis 4 has stage portion 9, and the first stiffener 1 has the through hole that internal diameter is less than stage portion 9 external diameter, the first stiffener 1 by the shaft part matched in clearance on through hole and stage portion 9, to be arranged at stage portion 9 place of hinge axis 4.Shown in Fig. 3, this first stiffener 1 is in suspended state, that is, this stage portion 9 can tangle the first stiffener 1.Fig. 1 shows the first stiffener 1 and also has the multiple connecting holes arranged around through hole.
In Fig. 3, also clearly illustrate the wear-resisting collar 2 (such as, in the present embodiment, the wear-resisting collar is the acetal resin collar, referred to as the POM collar) being socketed on hinge axis 4, and POM cover is located between stage portion 9 and the first stiffener 1.Hinge axis 4 is quill shaft, and one end of this quill shaft passes upper flap 3 and flange is clapped, and this flange is fixedly connected with upper flap 3 afterwards, and this is fixedly connected with preferably energy storage welding.
The assembling process of door body upper hinge of the present invention is as follows: first hinge axis 4 is loaded the POM collar, the first stiffener 1, upper flap 3 successively, then flange is clapped, and utilizes stored energy welding hinge axis 4 and upper flap 3 firmly to be welded together afterwards.Hinge axis 4 is made Step Shaft, makes its stage portion 9 tangle the first stiffener 1, when door body upper hinge is assemblied in fridge-freezer as described below, the effect of transmitting force can be played, make a body upper hinge load-bearing.Upper flap 3 and hinge axis 4 are utilized stored energy welding, welds together, ensure that its intensity.The POM collar, in the middle of the first stiffener 1 with hinge axis 4, when switch gate, effectively can reduce noise.
See Fig. 4 to Fig. 6, describe the fridge-freezer with above-mentioned door body upper hinge of the present invention, specifically describe the connection of the door body of door body upper hinge and fridge-freezer.In this embodiment, door body is provided with the upper panel 6 and side decorative strip 8 that are connected to each other, side decorative strip 8 is positioned at the side near door body center of rotation, and herein, the positioning sleeve 62 of Men Tizhong shows as and upper panel 6 global formation, axle sleeve 5 is fixed with in positioning sleeve 62, hinge axis 4 is rotatably assorted by axle sleeve 5 and positioning sleeve 62, and door body upper hinge is fixedly connected with casing by upper flap 3, and hinge axis 4 is fixedly connected with upper flap 3, thus door body rotates around hinge axis 4, Men Tiyu body pivot coordinates.Also show the joint detail of axle sleeve 5 and positioning sleeve 62 in Fig. 6, axle sleeve 5 stretches in positioning sleeve 62 and is also clasped with it.
The assembling of the door body of door body upper hinge and fridge-freezer is below described.Before door foaming, axle sleeve 5, upper panel 6, second stiffener 7, side decorative strip 8 are first assembled together: when pre-installing before door foaming, first the mode that the second stiffener 7 and side decorative strip 8 are inserted by side is fitted together, again the second stiffener 7 is installed on upper panel 6 together with side decorative strip 8, utilize screw upper panel 6 and the second stiffener 7 to be fixed, finally axle sleeve 5 is installed in the positioning sleeve 62 of upper panel 6 by buckle.Then seal, door foaming.Further, as shown in Figure 6, by the upper hinge assembled, load in axle sleeve 5, screw is utilized the first stiffener 1, upper panel 6, second stiffener 7 to be fixed, so that door body upper hinge is fixedly connected on upper panel 6, this is fixedly connected with the hinge axis 4 that makes to be rotatably assorted with axle sleeve 5 and is fastenedly connected at axis direction and the positioning sleeve 62 being formed at panel 6, and door body upper hinge can load-bearing shared the weight of door body thus.As shown in Figure 6, now, the first stiffener 1 compresses the stage portion 9 of hinge axis 4 downwards vertically and is fastenedly connected with positioning sleeve 62, and the POM collar is in compacted state.
See Fig. 7, the joint detail of the second stiffener 7 and side decorative strip 8 is described, second stiffener 7 comprises: be connected to the first kink 71 of panel 6 and be connected to the second kink 72 of side decorative strip 8, and wherein, the first kink 71 also has the perforate be socketed with positioning sleeve 62; The longitudinal edge of the second kink 72 is provided with breach 73, is provided with rib 81 in side decorative strip 8, and by coordinating of breach 73 and rib 81, the second kink 72 is mounted in side decorative strip 8.Thus when the first kink 71 is fastenedly connected with upper panel 6, this second kink 72 upwards holds side decorative strip 8, and namely side decorative strip 8 is hung on the second kink 72.Second stiffener 7 by side decorative strip 8 and upper panel 6 connection reinforcement, can make a body in the process of upper hinge load-bearing, serves the effect of sidewall transmitting force, thus side decorative strip 8 can not be made to be separated with upper panel 6.In addition, at a right angle between the first kink 71 and the second kink 72 shown in Fig. 7.
Fridge-freezer of the present invention can be refrigerator, refrigerator etc., and the first stiffener, the second stiffener are iron piece.
The invention has the beneficial effects as follows: because suspention on hinge axis has the first stiffener of matched in clearance with it, and hinge axis is fastenedly connected at axis direction by the positioning sleeve of the first stiffener and door body, thus door body upper hinge shares the weight of a part of door body, a body can not be tilted, this makes fridge-freezer outward appearance clean and tidy, extends the application life of fridge-freezer;
Further, because the second stiffener can, by side decorative strip and upper panel connection reinforcement, make a body upper hinge in the process of load-bearing, serve the effect of sidewall transmitting force, thus side decorative strip can not be made to be separated with upper panel, structural strength of the present invention is better thus, and structure is more stable;
Moreover, because door body upper hinge of the present invention comprises the wear-resisting collar, this reduce a frictional force when body rotates and noise.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
