If a user desire that using the function of containing articles of drawer 5, as shown in figure 4, then by stop block 32b along sliding rail 34a
In slideway inwardly elapse, hit sliding block 32a on have oblique slideway, sliding block can be made to move up, later drawer pull out when backstop sliding block
32a is hit less than self-locking column 25a, and self-locking to unlock, link mechanism remains stationary.Self-lock rod 25 not can rotate, sliding rail backstop
30 not can rotate, then sliding rail can continue to extract out.Drawer can horizontal standard-sized sheet, used as normal stored frozen room.At this time
Upper drawer 5 can also be opened normally, and function of containing articles is carried out.
In order to enable target drawer to stop in specified height, as is shown in figures 5-12, being arranged one in support base 23 can
The lock piece 40 of rotation.When link mechanism swing rise when, the second swing rod 22 rotation, when as it can be seen in figures 5 and 6, above
Correction block 22a is touched less than lock piece, then following latch 22b can also be passed through, when the second swing rod 22 is by the first backstop 23a
Constraint when reaching horizontal position, correction block 22c can touch lock piece 40 and turn an angle, and put down handle latch at this time
22b will be self-locking between lock piece 40.In some embodiments, latch front end geometry is the circle tangent with lock piece face
Arc, up can smoothly produce, and then interfere down self-locking.When drawer vacantly rests on specified altitude assignment, user take or
Person stores housekeeping operation.Certainly in other embodiments, as long as meeting drawer in predeterminated position locking, lock piece and latch
It interferes, during drawer decline, lock piece and latch are not interfered.This is not interfered it is appreciated that two
Person both nearest positions edge only tangent；Or the two is not in contact in spacing.
If Fig. 8 is when use finishes, lifting handle correction block 22c touches lock piece, lock piece rotation one to user again
Determine angle, the lower end for putting down mechanism latch 22b can touch the rotation of lock piece 40, and smoothly come downwards to lowest part, then sliding rail
Level sliding, freezing chamber are closed the door.
When such as Fig. 9 is when the second 22 uplink of swing rod, correction block 22a can touch lock piece 40, then will be in latch
22b is touched and is stirred its rotation before it, and when latch 22b touches lock piece, as shown in figs. 10-11, lock piece can be after
Continuous rotation, the circular arc line of latch can pass through, and both avoid self-locking in lower section and drawer cannot continue to rise, and locking
Restore to be in position shown in fig. 5 in the position of part.
Since correction block 22a needs to be on the circular arc line extended line of latch 22b, or 1 point more outward, at this time when
