Abstract
The utility model provides a hinge structure on a drying box door, which comprises a box side hinge and a door side hinge, wherein the box side hinge is arranged on a drying box body frame, a hinge shaft is penetrated and arranged in the box side hinge, and the door side hinge is arranged on the drying box door. The utility model is characterized in that composite bearings are sheathed outside both ends of the hinge shaft, one end of a rotating hinge block is connected with the box side hinge through the hinge shaft, and the other end of the rotating hinge block is connected with the door side hinge through an auxiliary hinge shaft. The utility model has the advantages that the drying box door can be easily and conveniently moved, the work intensity can be reduced, the noise for closing the door is low, and the door can not be easily inclined after being tightly closed. The automatic door opening can be realized.
Description
Technical field
The utility model relates to the blind hinge structure on the dry chamber door of freeze dryer, belongs to the hinge means technical field.
Background technology
Used stainless steel blind hinge structure on dry chamber door of present large-scale freeze dryer and the casing frame, belong to the single shaft hinge, its structure comprises case side hinge 1, taper bolt 2, hinge axis 3, soket head cap screw 4, composite bearing 5, reveal hinge 6, hinge back-up ring 7, circlip 8, soket head cap screw 9, limiting plate 10 and hex bolts 11 compositions as shown in Figures 1 and 2.Its shortcoming is because the deadweight of large-scale dry chamber door itself is bigger and the existence of gasket, with handgrip drying chamber door push the drying box frame interior and draw back outward in the drying box frame very painstaking.Main cause is the existence of the mounting hole of installation shaft, when utilizing rear cabinet to vacuumize to close chamber door, can produce very big noise, chamber door closes problems such as tight and chamber door integral inclination.
Summary of the invention
The purpose of this utility model provides and a kind ofly makes dry chamber door can move twin shaft rotary gemel structure easily, and the sound that this hinge arrangement is fastened chamber door is also very little, and chamber door integral body can be because of being tilted to some extent by the vacuum impact force yet.
In order to achieve the above object, the technical solution of the utility model has provided the hinge arrangement on a kind of dry chamber door, comprise case side hinge and reveal hinge, case side hinge is located on the drying box frame, is equipped with hinge axis in case side hinge, and the reveal hinge is located on the dry chamber door, it is characterized in that, be arranged with composite bearing outside the two ends of hinge axis, an end of rotary gemel piece links to each other with case side hinge by hinge axis, and the other end links to each other with the reveal hinge by the secondary hinge axle.
At described secondary hinge outer shaft sleeve oilless bushing is arranged.
Hinge between described reveal hinge and described rotary gemel piece is paid and is provided with the adjusting bolt.
The utility model adopts the secondary hinge axle to substitute the kidney slot structure of blind hinge, make dry chamber door can not cause tilting and go in the drying box frame or in the drying box frame to draw back phenomenon very laboriously, thereby alleviated operating personnel's working strength owing to the deadweight reason with hand push.After drying box vacuumizes, when fastening door, the little and difficult inclination of the noise that is produced.
The utility model has the advantages that to make moving easily of dry chamber door that reduce labor intensity, the noise of closing the door is little, is difficult for tilting behind the door closure.Can realize opening the door automatically.

The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 3 and 4, hinge arrangement on a kind of dry chamber door that provides for the utility model comprises that reveal hinge 6, case side hinge 1, hinge axis 3, secondary hinge axle 14, rotary gemel piece 13, composite bearing 12, oilless bushing 15, first mark closely screw 4, second and mark closely screw 17, first taper bolt 2, second taper bolt 18, limiting plate 10, limited bolt 11 and regulate bolt 16.
Reveal hinge 6 marks closely screw 17 by second and second taper bolt 18 is installed on the dry chamber door, and case side hinge 1 marks closely screw 4 by first and first taper bolt 2 is installed on the drying box frame.Middle part at case side hinge 1 is provided with hinge axis 3.Two ends at hinge axis 3 put composite bearing 12 respectively.One end of rotary gemel piece 13 links to each other with case side hinge 1 by hinge axis 3, and the other end links to each other with reveal hinge 6 by secondary hinge axle 14.At secondary hinge axle 14 overcoats oilless bushing 15 is arranged.Limiting plate 10 is installed on the case side hinge 1 by limited bolt 11, and the hinge that adjusting bolt 16 is installed between reveal hinge 6 and the rotary gemel piece 13 is paid, and is used to regulate the minim gap between dry chamber door and the drying box frame.And hinge axis 3 and secondary hinge axle 14 two rotatablely move cooperate be used to regulate chamber door compress with sealing ring and do not have when compressing between slightly larger gap, it is free and relaxed to open the dry chamber door of freeze dryer like this, and chamber door is difficult for inclination.
