Of course, the handle 10 provided in the present application may also be applied to doors of some houses, for example, a door body or a door frame of a refrigerator, but is not limited thereto.

The rotating shaft 4 is used for rotatably connecting the mounting seat 1 and the handle main body 2. One end of the rotating shaft 4 is fixedly connected with one of the mounting seat 1 and the handle main body 2, and the other end of the rotating shaft 4 is rotatably connected with the other of the mounting seat 1 and the handle main body 2. As shown in fig. 2 to 3, one end of the rotation shaft 4 is fixedly coupled to the handle main body 2. The mounting base 1 is provided with a shaft hole. The other end of the rotating shaft 4 is rotatably arranged in the shaft hole. Of course, a rotary bearing may be provided in the shaft hole. In some embodiments, a second reset mechanism 3 may be further disposed between the handle body 2 and the mounting base 1, so that the handle body 2 can be automatically restored to the original position after the user rotates the handle body 2. The present embodiment does not limit the specific structure of the second reset mechanism 3, for example, the second reset mechanism 3 may be a torsion spring structure.

Referring to fig. 4, fig. 4 is a schematic structural view of a handle main body of the handle provided by the present application, the handle main body being provided with a guide groove. The handle body 2 is provided with a guide groove 21. The guide groove 21 has a guide area 21a and an opening area 21 b. The end of the opening area 21b remote from the guide area 21a has an opening 21 c. The opening 21c is located at the edge of the handle body 2. The guide groove 21 has a first guide wall 211. The first guide wall 211 has a first sub-wall 2111 and a second sub-wall 2112. The first sub-wall 2111 is located at the opening area 21 b. The second sub-wall 2112 is located at the guide area 21 a. The first sub-wall 2111 and the second sub-wall 2112 are tangent. The first sub-wall 2111 has a first end facing the opening 21c and a second end remote from the opening 21 c. In a direction from the second end towards the first end. The distance between the first sub-wall 2111 and the axial center of the rotating shaft 4 gradually increases. The first guide wall 211 is an inner side wall of the guide groove 21, and when the guide rod 20 moves along the guide groove 21, the distance from the guide rod 20 to the axis of the rotating shaft 4 is gradually reduced from the opening 21c of the guide groove 21 to the side of the guide groove 21 away from the opening 21 c. That is, the door 40 and the cabinet 30 of the refrigerator 100 are close to each other from the opening 21c of the guide groove 21 to the side of the guide groove 21 away from the opening 21 c. It should be noted that, the guide groove 21 on the handle main body 2 needs to be matched with the guide rod 20 on the door body 40, when the handle main body 2 is disposed on the refrigerator body 30 of the refrigerator 100, the guide groove 21 is located at one end of the handle main body 2 close to the door body 40, and the rotating shaft 4 is located at one end of the handle main body 2 close to the refrigerator body 30, so that the distance from the guide rod 20 to the axis of the rotating shaft 4 gradually decreases, that is, the distance from the guide rod 20 to the refrigerator body 30 gradually decreases, and the guide rod 20 is fixed on the door body 40, that is, the distance from the door body 40 to the refrigerator body 30 gradually decreases. On the contrary, when the distance between the guide bar 20 and the axis of the rotating shaft 4 is gradually increased, that is, the distance between the door 40 and the cabinet 30 is gradually increased.

When the handle body 2 is rotatably disposed on the mounting seat 1, the guide groove 21 is disposed on the handle body 2 on a side close to the mounting seat 1. When the door is closed, the handle 10 is rotated to make the guide rod 20 enter the opening area 21b and the guide area 21a of the guide slot 21 from the opening 21c of the guide slot 21 in sequence until the guide rod 20 is locked with the handle 10, so that the door 40 of the refrigerator 100 can be tightly locked with the refrigerator body 30. After the door 40 of the refrigerator 100 is closed under the magnetic attraction thereof, the door 40 may be further close to the refrigerator body 30 by pressing the seal strip between the door 40 and the refrigerator body 30. When the door is closed, the guide rod 20 enters the guide groove 21 from the beginning to the process of locking and matching with the handle 10, which is the process of approaching the door body 40 to the box body 30, so that the tightness of closing the door body 40 when the guide rod 20 is locked with the handle 10 can be ensured.

Referring to fig. 5, fig. 5 is a schematic view illustrating the guide bar being separated from the guide groove during the process of unlocking the handle from the guide bar. When the door is opened, the handle 10 is rotated to move the guide rod 20 along the guide groove 21 towards the opening 21c to the opening area 21b, the guide rod 20 is generally abutted against the first sub-wall 2111 under the action of negative pressure, the handle 10 is continuously rotated, the guide rod 20 moves towards the first end along the first sub-wall 2111, and therefore the first sub-wall 2111 drives the guide rod 20 to move towards the direction away from the axis of the rotating shaft 4, namely the door body 40 is driven to move towards the direction away from the box body 30, so that the negative pressure can be overcome, and the effect of assisting in opening the door is achieved.

The handle main body 2 may further be provided with a handle 27, when the door is opened or closed, a user may rotate the handle main body 2 by holding the handle 27, which is convenient for operation, and the specific shape of the handle 27 is not limited in this embodiment, as shown in fig. 2-3, the handle 27 may be a bent rod-shaped structure.

In the handle 10 of the embodiment of the present application, the first guide wall 211 is disposed such that the first sub-wall 2111 of the first guide wall 211 is disposed in the opening area 21b, and the distance between the first sub-wall 2111 and the axial center of the rotating shaft 4 is gradually increased along the first sub-wall 2111 from the second end toward the first end. When the handle 10 is rotated to open the door, the first sub-wall 2111 can drive the guide rod 20 to move in a direction away from the axis of the rotating shaft 4, that is, the door 40 of the refrigerator 100 is driven to move in a direction away from the refrigerator body 30, so as to achieve the effect of assisting in opening the door. In addition, the opening 21c is arranged at the end of the opening area 21b of the guide groove 21 far away from the guide area 21a, the opening 21c is arranged at the edge of the handle main body 2, and the first sub-wall 2111 has the first end towards the opening 21c, so that the first sub-wall 2111 can drive the guide rod 20 to move in the direction far away from the axis until the guide rod 20 is separated from the guide groove 21, which is equivalent to prolonging the boosting process of the first sub-wall 2111 on the guide rod 20, improving the effect of boosting the door to open the door, and making the handle 10 more labor-saving to use.

Referring to fig. 2-4, after door 40 and body 30 of refrigerator 100 are closed by magnetic attraction of the user, the degree of pressing force applied to door 40 by the user is different after the user closes the refrigerator, and the amount of deformation of the sealing strip between door 40 and body 30 is different, which may cause different positions of guide bar 20 on door 40 relative to opening 21c of guide slot 21 of handle 10 on body 30. And when the handle 10 and the guide bar 20 are installed for use, the guide bar 20 may not enter the guide groove 21 at the opening 21c due to an installation error. In another embodiment of the present application, the handle main body 2 is further provided with a guide block 22 and an escape groove 23. The guide block 22 is movably disposed at the opening area 21 b. The first sub-wall 2111 is located at a surface of the guide block 22 that is tangent to the second sub-wall 2112. The escape groove 23 communicates with the guide groove 21. When the guide bar 20 enters the guide groove 21 and abuts against the guide block 22, the handle 10 is rotated to drive the guide bar 20 to move the guide block 22 into the escape groove 23, so that the guide block 22 avoids the opening area 21b to enable the guide bar 20 to enter the guide groove 21.

Referring to fig. 8, fig. 8 is a schematic view illustrating the guide rod pushing the guide block to move toward the avoiding groove during the locking process of the handle and the guide rod provided by the present application. The guide block 22 is movably disposed in the opening area 21b in a movable manner or a rotatable manner. For example, in some embodiments, the handle body 2 is provided with a first mounting portion 24, and the guide block 22 is pivotally connected to the first mounting portion 24. The first mounting portion 24 is provided with a convex arc surface 243, a first limiting surface 241 and a second limiting surface 242, the first limiting surface 241 is arranged at one end of the convex arc surface 243 close to the opening 21c, and the second limiting surface 242 is arranged at one end of the convex arc surface 243 far away from the opening 21 c; the first and second limiting

surfaces

241 and 242 are used for limiting the movement range of the guide block 22 along the convex arc surface 243. The first limiting surface 241 and the second limiting surface 242 may be flat surfaces extending outward from the circumference of the convex arc surface 243.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a guide block in a handle according to the present application. The present embodiment does not limit the specific structure of the guide block 22, for example, in some embodiments, the first sub-wall 2111 has a convex arc shape. The guide block 22 further includes a connecting portion 221 and a second mounting portion 222, and the connecting portion 221 is used to connect the first sub-wall 2111 with the second mounting portion 222. The connection portion 221 is further provided with a fitting groove 223. When the guide block 22 is mounted on the first mounting portion 24, the first mounting portion 24 is engaged with the engagement groove 223, and then the first mounting portion 24 and the second mounting portion 222 are rotatably connected. The present embodiment does not limit the specific structure of the rotational connection between the first mounting portion 24 and the second mounting portion 222, for example, the second mounting portion 222 is provided with a shaft hole, a rotating shaft is used to penetrate through the shaft hole, then two ends of the rotating shaft are disposed on the handle body 2, one end of the rotating shaft can be disposed on the first mounting portion 24 of the handle body 2, so as to realize the rotational arrangement of the guide block 22 on the handle body 2. By arranging the embedding groove 223, the first installation part 24 can be embedded in the embedding groove 223, so that the guide block 22 can be stably installed, the first installation part 24 can be prevented from protruding out of the side face of the handle 10, and the situation that the guide groove 21 is far away from the equipment to be installed and cannot be fully matched with the guide rod 20 when the handle 10 is installed is avoided.

In some embodiments, a first return mechanism 25 may also be disposed between the guide block 22 and the first mounting portion 24. The first return mechanism 25 can drive the guide block 22 to retreat from the escape groove 23. The state when the guide block 22 contacts the first stopper surface 241 in fig. 4 is the initial state of the guide block 22. When the guide rod 20 pushes the guide block 22 to rotate towards the escape groove 23, after the guide rod 20 enters the guide groove 21 and is disengaged from the guide block 22, the guide block 22 returns to the initial position, so that the guide rod 20 can be driven to move along the first sub-wall 2111 until the guide rod 20 is disengaged from the guide groove 21 when the door is opened. The present embodiment does not limit the structure of the first return mechanism 25, and for example, the first return mechanism 25 may be a torsion spring.

Referring to fig. 8, the specific shape of the avoiding groove 23 is not limited in this embodiment, for example, in some embodiments, the avoiding groove 23 may be an arc-shaped groove. The inner side of the avoiding groove 23 comprises a section of concave arc 231. The concave arc surface 231 is disposed opposite to the convex arc surface 243 on the first mounting portion 24. An end of the concave arc surface 231 near the guide groove 21 is connected to an end of the second sub-wall 2112 near the opening 21 c.

Referring to fig. 7-8, fig. 7 is a schematic view illustrating the guide bar abutting against the guide block during the locking process of the handle and the guide bar provided by the present application; fig. 8 is a schematic view illustrating the guide rod pushing the guide block to move toward the avoiding groove during the locking process of the handle and the guide rod provided by the present application. In the handle 10 provided in the embodiment of the present application, the guide block 22 and the avoiding groove 23 are disposed on the handle 10, the first sub-wall 2111 is disposed on the guide block 22, when the door is closed, as shown in fig. 7, when the guide rod 20 enters the guide groove 21, the guide rod 20 abuts against the guide block 22, and since the movable guide block 22 is movably disposed on the handle main body 2, the handle 10 is continuously rotated at this time, and the guide rod 20 can push the movable guide block 22 to move towards the avoiding groove 23, as shown in fig. 8, the opening 21c of the opening area 21b of the guide groove 21 is equivalently enlarged, so that the guide rod 20 can smoothly enter the guide groove 21. When the door is opened, the guide rod 20 pushed by the first sub-wall 2111 on the guide block 22 moves in the direction away from the axis of the rotating shaft 4 until the guide rod 20 is separated from the guide groove 21, so that the assisting effect of the first guide wall 211 on the guide rod 20 in the door opening process is prolonged, an opening 21c of the guide groove 21 in a large range is provided, the applicability of the handle 10 is improved, and the requirement on the installation accuracy of the handle 10 and the guide rod 20 is low during installation and use.

Referring to fig. 9, fig. 9 is a schematic view illustrating the guide bar entering the guide groove when the guide bar abuts against the second guide wall during the locking process of the handle and the guide bar provided by the present application. In another embodiment, the guide groove 21 further has a second guide wall 212 disposed opposite to the first guide wall 211. The second guide wall 212 has a third end facing the opening 21c and a fourth end facing away from the opening 21 c. The distance between the second guide wall 212 and the axial center of the rotary shaft 4 gradually decreases in the direction from the third end toward the fourth end. The second guide wall 212 may be a concave arc-shaped side wall. The second guide wall 212 is used to drive the guide rod 20 to move toward the axial center of the rotating shaft 4, i.e., drive the door 40 of the refrigerator 100 to approach the cabinet 30.

When the guide rod 20 enters the guide groove 21, it can abut against the second guide wall 212, which means that after the door 40 of the refrigerator 100 is normally closed under the action of the magnetic attraction, the distance between the guide rod 20 and the axis of the rotating shaft 4 is relatively large. If the second guide wall 212 is not provided, the user needs a large force to push the door 40 when closing the door, so that the door 40 approaches the cabinet 30, and the guide bar 20 enters the guide groove 21. In the handle 10 provided in the embodiment of the application, by providing the second guide wall 212, when the guide rod 20 is far away from the axis of the rotating shaft 4, a user may push the door body 40 first to enable the guide rod 20 to enter the opening 21c of the guide groove 21, and the guide rod 20 will abut against the second guide wall 212 after entering the guide groove 21, so as to rotate the handle 10, and thus the second guide wall 212 may drive the guide rod 20 to move along the guide groove 21 to a position where the guide rod is locked with the guide groove 21. It can be seen that the handle 10 provided in the embodiment of the present application can also achieve the effect of assisting in closing the door.

In some embodiments, the second guiding wall 212 is a concave arc-shaped side wall, and the first guiding wall 211 and the second guiding wall 212 form two side walls of the guiding slot 21.
