Abstract
The invention discloses a kind of MOD hingen mechanism with sealability, comprise door-plate, door frame and rotating shaft, the rotation lug place of described door-plate is provided with rectangle blind hole, the rectangle positioning boss coordinated with described blind hole is provided with in the end of described rotating shaft, described positioning boss bottom is provided with cylinder, in the gear-box of described door frame, relevant position is provided with cylindrical hole, described cylinder is through described cylindrical hole, described positioning boss enters described blind hole, and described cylinder is that curved surface is engaged with described cylindrical hole end face cooperation place.Advantage of the present invention is the structure of the connecting end surface by improving rotating shaft cylinder and door frame gear-box cylindrical hole, make it have good sealability, thus effectively stop steam, fog in refrigerator to enter gear-box, improve reliability and the electrical endurance of MOD hingen mechanism.
Description
Technical field
The present invention relates to the hingen mechanism of a kind of refrigerator MOD, particularly a kind of MOD.
Background technique
As shown in accompanying drawing 1,2, traditional MOD hingen mechanism, comprise door-plate 1, door frame 2 and rotating shaft 3, rotation lug 11 place of door-plate 1 is provided with rectangle blind hole 12, the rectangle positioning boss 31 coordinated with blind hole 12 is provided with in the end of rotating shaft 3, positioning boss 31 bottom is provided with cylinder 32, in the gear-box of door frame 2, relevant position is provided with cylindrical hole 21, cylinder 32 and cylindrical hole 21 end face cooperation place a, b all present plane form, cylinder 32 is through cylindrical hole 21, positioning boss 31 enters blind hole 12, drives door-plate to realize opening the door and the action of closing the door.Because cylinder 32 and cylindrical hole 21 exist matching gap, there is axial clearance in door-plate and door frame, causes steam in refrigerator, fog enters in door frame gear-box, cause harmful effect, easily cause product early failue to the component such as motor, gear shaft.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of MOD hingen mechanism with sealability, stops steam, fog in refrigerator to enter in the door frame gear-box of MOD.
Technological scheme: a kind of MOD hingen mechanism with sealability, comprise door-plate, door frame and rotating shaft, the rotation lug place of described door-plate is provided with rectangle blind hole, the rectangle positioning boss coordinated with described blind hole is provided with in the end of described rotating shaft, described positioning boss bottom is provided with cylinder, in the gear-box of described door frame, relevant position is provided with cylindrical hole, described cylinder is through described cylindrical hole, described positioning boss enters described blind hole, and described cylinder is that curved surface is engaged with described cylindrical hole end face cooperation place.
Described cylinder bottom is provided with ring-type convex tendon, and described cylindrical hole end face relevant position is provided with the annular recess matched with described ring-type convex tendon, and ring-type convex tendon inserts in annular recess and forms sealing surface cooperation.
Fill between described cylinder and described cylindrical hole end face and fill lubricant grease, play the effect of isolated sealing further.
Beneficial effect: compared with prior art, advantage of the present invention is the structure of the connecting end surface by improving rotating shaft cylinder and door frame gear-box cylindrical hole, make it have good sealability, thus effectively stop steam, fog in refrigerator to enter gear-box, improve reliability and the electrical endurance of MOD hingen mechanism.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in figures 3-5, a kind of MOD hingen mechanism with sealability, comprise door-plate 1, door frame 2 and rotating shaft 3, rectangle blind hole 12 is vertically provided with at rotation lug 11 place of door-plate 1, the rectangle positioning boss 31 coordinated with blind hole 12 is provided with in the end of rotating shaft 3, positioning boss 31 bottom is provided with cylinder 32, in the gear-box of door frame 2, relevant position is provided with cylindrical hole 21, cylinder 32 bottom is provided with ring-type convex tendon 33, cylindrical hole 21 end face relevant position is provided with the annular recess 22 matched with ring-type convex tendon 33, fill in annular recess 22 and fill lubricant grease 4.
During assembling, the cylinder 32 of rotating shaft 3 is through cylindrical hole 21, and ring-type convex tendon 33 inserts in annular recess 22 and forms sealing surface cooperation, and positioning boss 31 enters blind hole 12, drives door-plate to realize opening the door and the action of closing the door.
Structural feature of the present invention is: be provided with ring-type convex tendon and annular recess in hingen cooperation place respectively at rotating shaft and door frame corresponding site, and lubricant grease is filled groove.Because lubricant grease has certain viscosity; can not run off from door frame annular recess during institution staff; so seal protection can be provided to door frame gear-box under rotation situation; steam in refrigerator, fog etc. can not enter gear-box inside; effectively improve the working environment of the component such as motor; greatly reduce its failure probability, improve electrical endurance and the reliability of product.
For this reason, cylinder 32 is not limited only to above ring-type convex tendon 33, annular recess 22 structure with the end face cooperation place of cylindrical hole 21, and end is that curved surface occlusion all can achieve the goal.
