Embodiment 1

[0055] The high-sealed door can adjust the angle positioning and the predetermined positioning angle of the self-closing hinge. It can be set from the predetermined positioning angle of 20 degrees to the predetermined setting angle of 180 degrees, and the predetermined setting angle is 20 degrees. From the positioning angle position of 180 degrees to the predetermined positioning angle of 180 degrees, the blades of the hinge can realize self-positioning at the starting point of any predetermined positioning angle position, and at the starting point of any predetermined positioning angle position, the blades of the hinge can be self-positioning The positioning position is below the starting point, so that the blades of the hinge can realize self-closing. The high-sealed flat door can adjust the angle positioning and self-closing hinge and the high-seal convex door can adjust the angle positioning and self-closing hinge, such as being suitable for installation in freezers, refrig...

Embodiment 2

[0065] It differs from Embodiment 1 in that: please illustrate Figure 29 to Figure 33 The lower part of the fixing plate of the solid seat is protruded with the above-mentioned convex seat, which accounts for about half of the fixed plate, and the hinge sleeve is located on the convex seat. The hinge 10 includes a shaft sleeve 11 and a blade 12 fixed on the outside of the shaft sleeve 11. The fixed seat 20 includes a fixed plate 25, a vertical bottom plate 22 and a protrusion 23 fixed on the vertical bottom plate 22. A shaft sleeve 21 is recessed on the end face of the vertical bottom plate 22 of the seat 23 . The connecting sleeve 50 is connected to the sleeve 21 of the shaft sleeve 11 and the boss 23, and the shaft sleeve 11 and the shaft sleeve 21 are arranged side by side, so that the blade 12 of the hinge 10 can be opposite to the shaft sleeve of the fixed seat 20 and the boss 23. 21 rotations, so that the hinge can constitute a high-seal convex door hinge structure and...

Embodiment 3

[0067] It differs from Embodiment 1 in that: Please refer to Figure 34 , the high-sealed door can adjust the angle positioning and self-closing hinge, including hinges, solid seats, solid rods and screw sleeves, the thin rod 42 of the screw sleeve 40 can rotate relative to the solid rod 30 and the solid seat 20; the thin rod 42 forms blade 12, because this thin bar 42 is fixed on the door leaf of high sealing type door by fastening screw 98. The shaft sleeve 11 constitutes a connecting sleeve 50, the hinge can rotate relative to the solid seat, and the solid rod has a screw; it also includes a plug and an adjustment seat, and the screw sleeve is connected to one end of the shaft sleeve in a rotatable and non-movable manner. The screw ring 43 is fixedly connected in the screw through hole of the axle sleeve 11 by the fastening screw 98, and the screw ring 43 can support the top screw sleeve 40, so as to prevent the screw sleeve 40 from falling down, and the plug is fixed on th...

Abstract

The invention discloses an angle-adjustable positioning and self-closing hinge of a high-sealing-performance door. The self-closing hinge comprises hinge bodies and an adjusting seat, wherein a fixingrod, two magnets, two springs and the adjusting seat are arranged between a barrel and a plug in a shaft sleeve of the two hinge bodies, a screw of the fixing rod is screwed with the barrel, the first spring abuts between the fixing rod and the front outer annular edge of a cup body and a gasket, and the two magnets are attracted with each other. The adjusting seat can be correspondingly matchedwith the second magnet, the plug and the cup bottom through rotation adjustment so as to adjust and decrease the distance between the second magnet and the plug. The adjusting seat can be correspondingly matched with the second magnet, the plug and the cup bottom of a cup body through rotation adjustment so as to adjust and decrease the separation distance and size of the second magnet and the first magnet. The adjusting seat can adjust predetermined positioning angles of the hinge bodies through corresponding matching to make the hinge bodies self-positioned at any predetermined angle position starting point between the predetermined positioning angles, and blades of the hinge at certain positioning angle positions between the predetermined positioning angles can achieve self closing under location position starting points.

Description

technical field [0001] The invention relates to a highly airtight door capable of adjusting angle positioning and a self-closing hinge. Background technique [0002] The China Patent Database has announced an invention whose utility model name is "A Lifting Hinge Device" and whose patent number is 2013208356551. It includes an upper hinge, a lower hinge, a transmission seat and a transmission rod. The upper hinge includes an upper shaft sleeve and an upper hinge blade fixedly connected to the upper shaft sleeve; the lower hinge includes a lower shaft sleeve and a lower hinge blade fixedly connected to the lower shaft sleeve; the transmission seat is fixedly connected to the upper shaft sleeve, and the bottom end of the transmission seat is concave A transmission chamber is provided, and a first helical part is provided on the rotating surface inside the transmission chamber. The transmission rod is fixedly connected to the lower shaft sleeve, and the outer rotating surface...
