[0047] It should be noted that, without conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] Combined Figure 1-10 As shown, the embodiments of the present disclosure provide a handle device 100 for a refrigeration device 50, and the handle device 100 includes a fixed seat 10 and a handle 20.

[0049] Combined Figure 4As shown, the fixing base 10 is provided with a first limiting portion 11; the handle 20 is rotatably connected to the fixing base 10 through the rotating shaft 30, and can move between an open position and a closed position relative to the fixing base 10, the handle 20 includes a first end 21 away from the rotating shaft 30 and a second end 22 close to the rotating shaft 30, and the first end 21 of the handle 20 is provided with a first limiting matching portion 211; wherein the first limiting matching portion 211 cooperates with the first limiting portion 11 to limit the handle 20 to the closed position.

[0050] The refrigeration equipment 50 described in the present application includes a freezer, a refrigerator, etc. The following description will be made by taking the refrigeration equipment 50 as a freezer as an example.

[0051] Combination Figure 2 and Figure 4 As shown, the handle 20 is in the closed position.

[0052] Combination Figure 4 As shown, in the closed position, the first end 21 of the handle 20 abuts against the fixing base 10, and the combination Figure 7 As shown, in the open position, the first end 21 of the handle 20 is separated from the fixing base 10. The handle 20 can assist in opening the refrigerator door 52 in the open position.

[0053] The handle 20 is rotatably connected to the fixing base 10 via the rotating shaft 30 and can move between an open position and a closed position. Figure 7 As shown. The first end 21 of the handle 20 is far from the rotating shaft 30, and the force arm it is subjected to is relatively long, so when subjected to external force, the torque is relatively large. Providing a limited support at the first end 21 of the handle 20 can prevent the handle 20 from rotating or shifting due to the external force acting on the first end 21 of the handle 20. By providing a limited support at the first end 21 of the handle 20, the torque formed by the external force can be effectively resisted, and the stable position of the handle 20 can be maintained.

[0054] At the same time, the first end 21 of the handle 20 is used as a gripping end, and the first position-limiting matching portion 211 is provided at the first end 21 of the handle 20. When operating the handle 20, a clearer and more intuitive positioning feedback can be provided, so that the user can feel that the handle 20 has reached the predetermined closing position. In this way, the handle 20 can be prevented from being damaged by excessive movement when closing the handle 20.

[0055] In the handle device 100 for the refrigeration equipment 50 provided in the embodiment of the present disclosure, the first limiting matching portion 211 is arranged at the first end 21 of the handle 20 away from the rotating shaft 30, and the fixed seat 10 is correspondingly provided with the first limiting portion 11. Through the cooperation between the first limiting portion 11 and the first limiting matching portion 211, a limiting support can be formed for the handle 20 at the first end 21 of the handle 20, thereby improving the stability of the handle 20 when it is in the closed position.

[0056] Optionally, in combination with Figure 4 As shown, the first limiting portion 11 includes a first limiting surface 111, and the first limiting and mating portion 211 includes a first limiting and mating surface 212. The first limiting surface 111 is adapted to the first limiting and mating surface 212. When the handle 20 is in the closed position, the first limiting surface 111 is in contact with the first limiting and mating surface 212, so that the first end 21 of the handle 20 is limited to the fixed seat 10.

[0057] The first limiting surface 111 is adapted to the first limiting and mating surface 212. When the handle 20 is in the closed position, the first limiting surface 111 and the first limiting and mating surface 212 can be in close contact, improving the limiting effect.

[0058] The first limiting portion 11 and the first limiting and mating portion 211 achieve limiting and mating through the way of surface matching, which can increase the mating surface between the first limiting portion 11 and the first limiting and mating portion 211, thus improving the limiting effect. When the handle 20 is in the closed position, the first limiting surface 111 is in contact with the first limiting and mating surface 212, which can accurately position the handle 20 in the closed position. This design can also reduce the swing of the first end 21 of the handle 20 when it is closed, improving the stability of the handle device 100.

[0059] Optionally, in combination with Figure 4 As shown, the first limiting surface 111 extends in an arc-shaped depression towards the first end 21 of the handle 20, and the first limiting and mating surface 212 extends in an arc-shaped protrusion towards the fixed seat 10.

[0060] The first limiting surface 111 and the first limiting and mating surface 212 are in contact through an arc-shaped concave surface and an arc-shaped convex surface, which can improve the stability of the mating.

[0061] Exemplarily, during the movement of the handle 20 towards the closed position, the first end 21 of the handle 20 rotates downward relative to the fixed seat 10, and the second end 22 of the handle 20 rotates upward relative to the fixed seat 10. The first limiting surface 111 is located below the handle 20, and the first limiting and mating surface 212 is provided on the lower surface of the first end 21 of the handle 20, and the first limiting surface 111 is adapted to the first limiting and mating surface 212. When the handle 20 is in the closed position, the first end 21 of the handle 20 abuts against the fixed seat 10, and the first limiting surface 111 cooperates with the first limiting and mating surface 212 to realize the limiting and supporting of the first end 21 of the handle 20.

[0062] Optionally, in combination with Figure 4 and Figure 7 As shown, the first limiting surface 111 extends along the normal direction of the rotation direction of the first end 21 of the handle 20.

[0063] The rotation direction of the handle 20 is as shown in Figure 7As shown, the first limiting surface 111 extends along the normal direction of the rotation direction of the first end 21 of the handle 20, that is, the first limiting surface 111 extends along the normal direction of the rotation trajectory of the first end 21 of the handle 20. Along the rotation direction of the first end 21 of the handle 20, the normal direction is perpendicular to the tangent on the rotation trajectory and points to the rotating shaft 30. As Figure 4 shown, when in the closed position, the first limiting surface 111 extends along the normal direction of the rotation direction of the first end 21 of the handle 20 and is in contact with the first end 21 of the handle 20.

[0064] The first limiting surface 111 extending along the normal direction of the rotation direction of the first end 21 of the handle 20 can provide a support perpendicular to the rotation plane for the first end 21 of the handle 20, thereby increasing the stability of the handle 20 in the closed position. Through the first limiting surface 111 extending in the normal direction, the handle 20 can be better supported in the closed position, and at the same time, the first end 21 of the handle 20 can be effectively restricted in the closed position, avoiding wear and deformation of the handle 20 caused by excessive movement of the first end 21 of the handle 20.

[0065] Optionally, as shown in Figure 7 the fixed seat 10 is further provided with a second limiting portion 12; the second end 22 of the handle 20 is provided with a second limiting and cooperating portion 221, and the second limiting portion 12 cooperates with the second limiting and cooperating portion 221 to limit the handle 20 in the open position.

[0066] As shown in Figure 5 and Figure 7 the handle 20 is in the open position.

[0067] The second limiting and cooperating portion 221 is arranged at the second end 22 of the handle 20, and the second end 22 of the handle 20 is close to the rotating shaft 30, and this position is the central area where the handle 20 rotates. During the process of the handle 20 rotating from the closed position to the open position, the second limiting portion 12 and the second limiting and cooperating portion 221 can interact with each other faster and provide limiting in time. This can improve the response speed of the limiting, so that the handle 20 can be quickly and accurately positioned in the open position.

[0068] When the handle 20 is in the open position, the cooperation between the second limiting portion 12 and the second limiting and cooperating portion 221 can provide a stable support point for the second end 22 of the handle 20, restricting the further rotation of the handle 20, thereby improving the stability of the handle 20 in the open position.

[0069] By the cooperation between the first limiting portion 11 and the first limiting and cooperating portion 211, the handle 20 can be restricted in the closed position, and by the cooperation between the second limiting portion 12 and the second limiting and cooperating portion 221, the handle 20 can be restricted in the open position. This design of two-way limiting can respectively improve the stability of the handle 20 in the closed position and the open position.

[0070] The first limit fitting portion 211 is provided at the first end 21 of the handle 20, and the second limit fitting portion 221 is provided at the second end 22 of the handle 20. Limit supports are respectively carried out at both ends of the handle 20, providing two stable support points during the rotation of the handle 20, restricting the swing of the handle 20 when it is opened and closed, thereby enhancing the structural stability of the handle device 100.

[0071] Compared with the related art in which the limit structures of the handle 20 at the open position and the closed position are provided at the same end of the handle 20, the embodiments of the present disclosure can also avoid problems such as excessive torque and structural imbalance caused by concentrated support points.

[0072] Optionally, in combination Figure 7 As shown, the second limit portion 12 includes a second limit surface 121, and the second limit fitting portion 221 includes a second limit fitting surface 222. The second limit surface 121 is adapted to the second limit fitting surface 222. When the handle 20 is in the open position, the second limit surface 121 is in contact with the second limit fitting surface 222, so that the second end 22 of the handle 20 is limited to the fixed seat 10.

[0073] The second limit surface 121 is adapted to the second limit fitting surface 222. When the handle 20 is in the open position, the second limit surface 121 and the second limit fitting surface 222 can be in close contact, improving the limit effect.

[0074] The second limit portion 12 and the second limit fitting portion 221 achieve limit fitting by means of surface matching, which can increase the mating surface between the second limit portion 12 and the second limit fitting portion 221, thereby improving the limit effect. When the handle 20 is in the open position, the second limit surface 121 is in contact with the second limit fitting surface 222, which can accurately position the handle 20 in the open position. This design can also reduce the swing of the second end 22 of the handle 20 in the open position, improving the stability of the handle device 100.

[0075] Exemplarily, during the movement of the handle 20 towards the open position, the first end 21 of the handle 20 rotates upward relative to the fixed seat 10, and the second end 22 of the handle 20 rotates downward relative to the fixed seat 10. The second limit surface 121 is located below the handle 20, and the second limit fitting surface 222 is provided on the outer surface of the second end 22 of the handle 20, and the second limit surface 121 is adapted to the second limit fitting surface 222. When the handle 20 is in the open position, the second end 22 of the handle 20 abuts against the fixed seat 10, and the second limit surface 121 cooperates with the second limit fitting surface 222 to realize the limit support for the second end 22 of the handle 20.

[0076] Optionally, the second limit surface 121 extends along the normal direction of the rotation direction of the second end 22 of the handle 20.

[0077] The second limiting surface 121 extends along the normal direction of the rotation direction of the second end 22 of the handle 20, that is, the second limiting surface 121 extends along the normal direction of the rotation trajectory of the second end 22 of the handle 20. Along the rotation direction of the second end 22 of the handle 20, the normal direction is perpendicular to the tangent on the rotation trajectory and points to the rotating shaft 30. When in the open position, the second limiting surface 121 extends along the normal direction of the rotation direction of the second end 22 of the handle 20 and is in contact with the second end 22 of the handle 20.

[0078] The second limiting surface 121 extending along the normal direction of the rotation direction of the second end 22 of the handle 20 can provide a support perpendicular to the rotation plane for the second end 22 of the handle 20, thereby increasing the stability of the handle 20 in the open position. Through the second limiting surface 121 extending in the normal direction, the handle 20 can be better supported in the open position, and at the same time, the second end 22 of the handle 20 can be effectively restricted in the open position, avoiding wear and deformation of the handle 20 caused by excessive movement of the second end 22 of the handle 20.

[0079] Optionally, as shown in Figure 4 and Figure 7 shown, the handle device 100 for the refrigeration device 50 further includes an assisting component 40. The assisting component 40 is arranged on the fixed seat 10, and the assisting component 40 cooperates with the handle 20 and can move between a assisting position extending out of the fixed seat 10 and a retracted position at least partially retracted into the fixed seat 10 relative to the fixed seat 10; wherein, when the handle 20 moves towards the open position, it drives the assisting component 40 to move towards the assisting position.

[0080] The assisting component 40 cooperates with the handle 20 and can move between the assisting position extending out of the fixed seat 10 and the retracted position. When the handle 20 moves towards the open position, the assisting component 40 provides additional force to overcome the difficulty of opening the door caused by the negative pressure in the freezer, effectively assisting the user to open the door easily.

[0081] Optionally, as shown in Figure 4 and Figure 7 shown, the fixed seat 10 is provided with a through hole 13. The assisting component 40 includes a ejector rod 41 and a sliding member 42. The ejector rod 41 passes through the through hole 13, and the ejector rod 41 can perform linear reciprocating motion relative to the through hole 13; the sliding member 42 is arranged inside the fixed seat 10. One side of the sliding member 42 is connected to the ejector rod 41, and the other side of the sliding member 42 cooperates with the second end 22 of the handle 20, so that when the handle 20 moves towards the open position, it drives the sliding member 42 to move, so as to drive the ejector rod 41 to move towards the assisting position relative to the through hole 13.

[0082] The slider 42 is engaged with the second end 22 of the handle 20. When the handle 20 moves towards the open position, it can drive the slider 42 to move. At the same time, the slider 42 is connected to the ejector rod 41. During the movement of the slider 42, it can drive the ejector rod 41 to move relative to the through hole 13 towards the boosting position. By the linear reciprocating movement of the ejector rod 41 relative to the through hole 13, the movement of the boosting assembly 40 between the boosting position and the retracted position is realized. In this way, when the handle device 100 is assembled to the door body 52 of the refrigerator, the boosting assembly 40 can move to the extended position to provide boosting when needed, and move to the retracted position when not needed without affecting the normal use of the door body 52.

[0083] Optionally, as shown in Figure 4 and Figure 10 the slider 42 is provided with a positioning portion 421, and the second end 22 of the handle 20 is provided with a positioning and mating portion 223. The positioning portion 421 is engaged with the positioning and mating portion 223 to position the handle 20 on the slider 42 when the handle 20 is in the closed position.

[0084] Through the cooperation between the positioning portion 421 and the positioning and mating portion 223, the second end 22 of the handle 20 can be positioned on the slider 42 when the handle 20 is in the closed position, preventing the second end 22 of the handle 20 from deviating from the closed position. When the handle 20 moves from the closed position towards the open position, the second end 22 of the handle 20 can more accurately cooperate with the slider 42, thereby driving the slider 42 to move. This can improve the cooperation effect between the handle 20 and the boosting assembly 40.

[0085] Optionally, as shown in Figure 4 and Figure 10 one of the positioning portion 421 and the positioning and mating portion 223 is a positioning protrusion 224, and the other is a positioning bayonet 422. Wherein, when in the closed position, the positioning protrusion 224 can be snapped into the positioning bayonet 422; when the handle 20 moves towards the open position, the positioning protrusion 224 can be disengaged from the positioning bayonet 422.

[0086] The positioning and mating structure of the positioning protrusion and the positioning bayonet has stable cooperation and simple structure. At the same time, during the assembly process of the handle device 100, there will be obvious positioning feedback when the positioning protrusion is snapped into the positioning bayonet, which can improve the assembly accuracy of the handle device 100.

[0087] It is possible that the positioning portion 421 is a positioning protrusion and the positioning mating portion 223 is a positioning bayonet. It is also possible that the positioning portion 421 is a positioning bayonet and the positioning mating portion 223 is a positioning protrusion. In the embodiments of the present disclosure, the positioning portion 421 is taken as the positioning bayonet 422 and the positioning mating portion 223 is taken as the positioning protrusion 224 as an example. The positioning bayonet is provided on the sliding member 42, and the positioning protrusion is provided at the second end 22 of the handle 20. In the closed position, the positioning protrusion 224 is snapped into the positioning bayonet 422 to position the second end 22 of the handle 20. When the handle 20 moves towards the open position, the positioning protrusion 224 disengages from the positioning bayonet 422, and the positioning protrusion 224 moves synchronously with the second end 22 of the handle 20, cooperates with the sliding member 42, and drives the sliding member 42 to move so as to drive the ejector rod 41 to move towards the boosting position.

[0088] Optionally, as shown in combination with Figure 4 and 10 shown, the positioning protrusion 224 is arranged as an arc-shaped protrusion.

[0089] The positioning protrusion 224 is arranged as an arc-shaped protrusion. When the handle 20 moves towards the open position, the arc-shaped protrusion 224 can slide smoothly relative to the positioning bayonet 422 and disengage from the positioning bayonet 422. Thus, while achieving the positioning function, it does not affect the normal movement of the second end 22 of the handle 20.

[0090] Optionally, as shown in combination with Figure 4 shown, the second end 22 of the handle 20 abuts against the sliding member 42 in the closed position.

[0091] The second end 22 of the handle 20 abuts against the sliding member 42 in the closed position, which can provide additional positioning support for the second end 22 of the handle 20 and improve the stability of the second end 22 of the handle 20 in the closed position.

[0092] Exemplarily, the second end 22 of the handle 20 and the sliding member 42 are arranged in the up-down direction. The upper surface of the second end 22 of the handle 20 is provided with a second limit mating surface 222, and the fixed seat 10 is provided with a second limit surface 121. The second limit mating surface 222 and the second limit surface 121 cooperate to limit the handle 20 to the open position. In the closed position, the lower surface of the second end 22 of the handle 20 abuts against the upper surface of the sliding member 42, which can naturally limit the lower surface of the handle 20 to the closed position and improve the limiting effect of the handle 20 in the closed position.

[0093] Optionally, as shown in combination with Figure 4 shown, the boosting assembly 40 further includes a reset member 43. The reset member 43 is arranged between the sliding member 42 and the fixed seat 10 to drive the boosting assembly 40 to move from the boosting position towards the retracted position.

[0094] When the slider 42 moves towards the assisting position, the space between the slider 42 and the fixed seat 10 decreases, and the restoring member located between the slider 42 and the fixed seat 10 deforms. After the assisting is completed, the restoring member automatically restores its deformation and can drive the assisting assembly 40 to move from the assisting position towards the retracted position. This can improve the automation effect of the handle device 100. The restoring member 43 can be a spring.

[0095] Combined Figure 1 As shown, an embodiment of the present disclosure provides a refrigeration device 50, which includes a cabinet 51, a door body 52, and a handle device 100 for the refrigeration device 50 as described in any one of the above-mentioned disclosed embodiments. The door body 52 is disposed on the cabinet 51 in an openable and closable manner; the handle device 100 for the refrigeration device 50 as described in any one of the above-mentioned disclosed embodiments is disposed on the door body 52.

[0096] The refrigeration device 50 provided by the embodiment of the present disclosure includes the handle device 100 for the refrigeration device 50 as described in any one of the above-mentioned disclosed embodiments, and thus has all the beneficial effects of the handle device 100 for the refrigeration device 50 as described in any one of the above-mentioned disclosed embodiments. Through the handle device 100, it is possible to assist in opening the door body 52 of the freezer, saving time and effort. At the same time, by the cooperation of the first limiting portion 11 and the first limiting cooperation portion 211, the stability of the handle 20 in the closed position can be improved.
