Enough to be slidably matched with curved support face 21, curved support face 21 plays a supporting role to retention bead 52, limits handle 5 around the
Rotation of one axis 41 to the direction of the side wall surface 201 close to refrigerator door makes to pull and begin in 51 drive 4 rotation process of revolving part of end
It is higher than the side wall surface 201 of refrigerator door eventually, the generation of side wall surface 201 for avoiding the bottom surface 511 and refrigerator door that pull end 51 is dry
It relates to and rubs.Although the scheme opened the scheme of arc groove on bracket 2 and set curved support face 21 on bracket 2 can avoid hand
The bottom surface 511 of pull end 51 interferes and rubs with the side wall surface 201 of refrigerator door, but compares and open arc groove on bracket 2
Scheme, retention bead 52 is to ride on curved support face 21 rather than cooperate in the scheme that bracket 2 sets curved support face 21, this
Sample keeps the processing request in curved support face 21 lower than the processing request of arc groove, and processing is easier, and can reduce limition orientation
The manufacturing cost of structure.
Referring to fig. 2, when opening refrigerator door or the reset of handle 5 by handle 5, handle 5 was easy around 41 inverse time of first axle
Needle rotates (referring to the direction in Fig. 2), and when especially opening refrigerator door, the force direction of user opponent's pull end 51 is different, handle 5
It is rotated counterclockwise with easy around first axle 41, when user exerts oneself excessive, handle 5 is easy another side wall surface 12 with embedded box 1
It is in contact friction, in order to limit the amplitude that handle 5 rotates counterclockwise around first axle 41, it is preferable that the opening lid of embedded box 1
Equipped with cover board (not shown), cover board is located at the side of handle 5 along its length, and retention bead 52 is located at cover board and arc branch
Between support face 21, cover board can prevent retention bead 52 from producing embedded box 1.Since retention bead 52 is located at cover board and curved support face
Between 21, when handle 5 rotates, cover board can make retention bead 52 be no more than embedded box 1 in 41 rotation process of first axle
Opening, i.e. prevention retention bead 52 produce embedded box 1, limit counterclockwise rotational steps of the handle 5 around first axle 41 in this way,
When excessive around the rotational steps counterclockwise of first axle 41 so as to avoid handle 5, another side wall surface 12 of handle 5 and embedded box 1
It is in contact friction.Wherein, handle 5 is the Y-direction in coordinate system in Fig. 2 along its length.
Referring to figs. 2 and 3, bracket 2 includes the first support plate 22 and the second support plate 23 that are parallel to each other, and revolving part 4
Between the first support plate 22 and the second support plate 23, shaft 3 is arranged in respectively in the first support plate 22 and the second support plate 23,
First support plate 22 is arranged close to handle 5, and curved support face 21 is the upper surface of the first support plate 22.By the way that revolving part 4 is set
It sets between the first support plate 22 and the second support plate 23, the both ends of revolving part 4 stress in its rotary course can be made in this way
Balance；The upper surface of first support plate 22 is set as curved support face 21, to can simplify the structure of bracket 2 in this way, it is not necessary to separately set
One support plate is used to support the retention bead 52 on handle 5.
In order to avoid the handle 5 during opening refrigerator doors and driving member 7 generate movement interference, as shown in Fig. 2, it is preferred that
Ground, first axle 41 and the second axis 42 are located at the two sides of revolving part 4.Since the second axis 42 of revolving part 4 is connected by driving member 7
The first end of mandril 6 is connect, driving member 7 is setting between revolving part 4 and mandril 6, and one end due to handle 5 in the width direction
Hinged with first axle 41, if first axle 41 and the second axis 42 are all located at the side of revolving part 4, handle 5 and driving member 7 are just
Positioned at the side of revolving part 4, during handle 5 opens refrigerator doors, handle 5 and driving member 7 are easy to produce movement interference, because
First axle 41 and the second axis 42, are separately positioned on the two sides of revolving part 4 by this, can be to avoid handle during opening refrigerator doors
Hand 5 and driving member 7 generate movement interference.
In order to make the second axis 42 that rotating lever preferably be driven to rotate during handle 5 drives revolving part 4 to rotate,
As shown in Figure 2, it is preferable that first axle 41 and the second axis 42 are located along the same line.In order to make handle 5 drive the rotation of revolving part 4
Turn more labor-saving, first axle 41 is typically all to be located at from 4 rotation center remote position of revolving part, the i.e. edge close to revolving part 4
Position, if the second axis 42 and first axle 41 are not located along the same line, handle 5 by first axle 41 drive revolving part
When 4 rotation, the second axis 42 is just asynchronous with first axle 41.Not due to the position of first axle 41 and the second axis 42 on revolving part 4
Together, during handle 5 drives 4 Unscrew refrigerator doors of revolving part by first axle 41, the second axis 42 is wide along embedded box 1
The displacement for spending direction will be less than handle 5 along the displacement of 1 width direction of embedded box (left and right directions in Fig. 2), make the second axis
42 push the rotational angle of rotating lever to reduce, and then the distance for making rotating lever that mandril 6 be pushed to eject embedded box 1 reduces, this
Sample can reduce the open door effect of handle 5.Therefore, on the same line by first axle 41 and the setting of the second axis 42, the can be made
Two axis 42 are synchronous with the movement of handle 5, make the second axis 42 that rotating lever preferably be driven to rotate, enhance the open door effect of handle 5.
Wherein, driving member 7 is not unique, for example driving member 7 can be cam, and cam and embedded box 1 are hinged, and the of cam
Second axis 42 of one end and revolving part 4 is against the second end of cam and the first end of mandril 6 are against when handle 5 drives revolving part
When 4 rotation, the second axis 42 is able to drive cam rotation, and the other end of cam pushes mandril 6 to eject to outside embedded box 1.In addition, such as
Shown in Fig. 2, driving member 7 can also be rotating lever, and rotating lever and embedded box 1 are hinged, the first end and revolving part 4 of rotating lever
The second axis 42 against, rotating lever second end and mandril 6 first end against.Compared to cam, rotating lever is easier to add
Work manufacture, manufacturing cost is low, and the both ends of rotating lever are easy to lean with the first end of the second axis 42, mandril 6.
It is more labor-saving during in order to make handle 5 open refrigerator doors, as shown in Figure 2, it is preferable that the first end of rotating lever
To rotating lever rotation center distance be greater than rotating lever second end to rotating lever rotation center distance.Due to
The first end of rotating lever and the second axis 42 of rotary shaft 3 lean, and the second end of rotating lever and the first end of mandril 6 are supported
It leans on, the second axis 42 of revolving part 4 is made to be greater than the arm of force that mandril 6 is lifted off door body resistance to the arm of force of rotating lever active force in this way,
Rotating lever constitutes laborsaving lever, more labor-saving during so that handle 5 is opened refrigerator doors.
When refrigerator doors completion opens user and removes the power of handle 5 pulled on end 51, mandril return unit 8 being capable of mandril
It completes to reset under the action of 8 reset force of return unit, in order to which mandril 6 again opens refrigerator doors next time.Wherein, mandril resets
Part 8 is not unique, for example mandril return unit 8 can be compressed spring, and the first end of mandril 6 is equipped with baffle, and the one of compressed spring
End leans with baffle, and the side wall of the other end and embedded box 1 leans.In addition, as shown in Fig. 2, mandril return unit 8 be torsional spring,
The first end 81 of torsional spring and the side wall 12 of embedded box 1 are against the second end 82 of torsional spring is connect with the first end of mandril 6.Phase
Than compressed spring, torsional spring axial length is relatively small, it is made to occupy little space, and torsional spring and 6 first end of mandril, embedded box 1
Side wall 12 connection structure it is simpler, do not need the another connection structures such as baffled.Wherein, torsional spring is to be sheathed on to be arranged pre-buried
In fixing axle 83 on the bottom surface 11 of box 1.
After user completes refrigerator doors opening, handle 5 is equally also required to reset.It can be realized by mandril return unit 8
The reset of handle 5, the second end that the reset force of mandril return unit 8 first acts on rotating lever rotate rotating lever, then turn
The second axis 42 that the first end of dynamic lever acts on revolving part 4 makes the rotation of revolving part 4 that handle 5 be driven to reset, but due to rotating thick stick
The second end of bar to rotating lever rotation center distance be less than rotating lever first end to rotating lever rotation center
Distance, at this moment rotating lever is laborious lever, and mandril return unit 8 needs very big reset force that could reset handle 5, in this way
It is unreliable in such a way that mandril return unit 8 resets handle 5.In order to reliably reset handle 5, as shown in Fig. 2, excellent
Selection of land, handle for refrigerator door component should also include handle return unit 9, and handle return unit 9 is used to apply reset force to handle 5.
Since the reset force of handle return unit 9 directly acts on handle 5, the reliable reset of handle 5 may be implemented in this way.
Wherein, the type of handle return unit 9 is not unique, for example handle return unit 9 can be extension spring, extension spring
Both ends are equipped with hook, and 1 side wall 12 of embedded box is equipped with groove, and limited post, the extending direction and shaft 3 of limited post are equipped in groove
Unanimously, one end of extension spring is hung in the retention bead 52 of handle 5, and the other end is hung on limited post, when use handle 5
When enabling, handle 5 drives revolving part 4 to rotate, and extension spring is stretched at this time；After the power on the knob end of handle 5 removes, draw
The elastic force for stretching spring can make revolving part 4 that handle 5 be driven to reset.
In addition, as shown in Fig. 2, handle return unit 9 can also be torsional spring, the first end 91 of torsional spring and the side wall of embedded box 1
13 against the second end 92 of torsional spring is connect with retention bead 52.It is fixed between first support plate 22 and the second support plate 23
Installation axle (not shown), the extending direction and shaft 3 of installation axle are consistent, and torsion spring set is set in installation axle.When user removes
After the power of handle 5 pulled on end 51, the second end 92 of torsional spring applies reset force to retention bead 52, and handle 5 is this multiple
It drives revolving part 4 to rotate counterclockwise under the action of the power of position, finally returns that initial position.Compared to extension spring, torsional spring is to pass through torsion
Turn to store power, the axial dimension of torsional spring is constant, its occupied space is smaller in this way, and torsional spring and retention bead 52, embedded box 1
The connection structure of side wall 13 is fairly simple, does not need separately to set the connection structures such as limited post.
Referring to fig. 2, the reset of handle 5 not only may be implemented in torsional spring, and retention bead 52 can also be prevented to far from curved support
The direction in face 21 rotates.Since the second end 92 of torsional spring is connect with retention bead 52, in this way during handle 5 resets,
The reset force that torsional spring applies to retention bead 52 can make limit convex in the component of the bottom surface 11 perpendicular to embedded box 1 in downward direction
It plays 52 to be tightly attached on curved support face 21, retention bead 52 can be prevented to rotate to the direction far from curved support face 21, in turn
It prevents handle 5 to rotate counterclockwise in reseting procedure around first axle 41, while also avoiding handle 5 and misplacing after the reset.
The structure type of revolving part 4 is not also unique, for example revolving part 4 can be rod piece, in addition, such as Fig. 2, Fig. 3 and Fig. 4 institute
Show, revolving part 4 can also be cam structure, compare rod piece, the intensity of cam is bigger, when user is firmly excessive when opening refrigerator doors
When, cam is less likely to occur to deform.
Handle for refrigerator door component provided in an embodiment of the present invention belongs to built-in handle 5, needs to be mounted on door body
Embedded box 1 is embedded at the inside of door body by inside, and can generally be equipped with heat preservation and heat-blocking action inside refrigerator door
Foaming layer can occupy a part of volume of door foaming layer if the depth of embedded box 1 is excessive, then being embedded with embedded box 1
The insulation effect of this part refrigerator door is bad, and very low temperature is easy to pass to embedded box 1 and handle 5 in refrigerator, when
Warm and humid air outside refrigerator is easy to that condensation occurs when encountering the wall surface of the lower handle 5 of temperature and embedded box 1.In order to solve
The problem of condensation is easy on handle 5, it is preferable that as shown in Figures 2 and 3, the rotation angle of revolving part 4 is less than or equal to 90 °, such as
The rotation angle of fruit revolving part 4 is spent greatly, in order to interfere revolving part 4 with embedded box 1 in rotary course, embedded box 1
Deeper depth is needed to meet the rotation of revolving part 4, therefore the condensation problem for being unfavorable for solving on handle 5 in this way will rotate
