In the related art, the push rod is arranged in the handle seat, and the push rod includes a body and a rod body, and the rod body is directly connected to one side of the body. During installation, the push rod connected in an integrated manner needs to be directly installed in the handle seat, which increases the difficulty of assembly.

[0049] Combination Figure 1-8 As shown, an embodiment of the present disclosure provides a handle assembly 100 for a refrigeration device, including a fixing seat 10 , a sliding member 20 and a push rod 30 .

[0050] The sliding member 20 is arranged on the fixed seat 10, and the sliding member 20 can move relative to the fixed seat 10, and the sliding member 20 is provided with a limiting portion 21; the push rod 30 is arranged on the fixed seat 10, the push rod 30 cooperates with the sliding member 20, and the push rod 30 can move relative to the fixed seat 10 between an assisting position extending out of the fixed seat 10 and a retracted position at least partially retracted into the fixed seat 10, and the push rod 30 is provided with a limiting matching portion 31; wherein, the sliding member 20 drives the push rod 30 to move toward the assisting position to assist in opening the door, and the limiting portion 21 cooperates with the limiting matching portion 31 to prevent the push rod 30 from moving relative to the sliding member 20.

[0051] like Figure 6 As shown, the ejector pin is in the retracted position. Figure 8 As shown, the push rod is in the power-assist position.

[0052] The sliding member 20 can move relative to the fixing seat 10, and the push rod 30 cooperates with the sliding member 20, and the sliding member 20 can drive the push rod 30 to move toward the power-assisting position. When the push rod 30 is in the power-assisting position, it can assist in opening the door and reduce the difficulty of opening the door body 62.

[0053] With the handle assembly 100 for refrigeration equipment provided by the embodiment of the present disclosure, the sliding member 20 and the push rod 30 are separately arranged. When assembling the handle assembly 100, the sliding member 20 is first installed in the fixing seat 10, and then the push rod 30 is inserted into the fixing seat 10 from the outside to cooperate with the sliding member 20, which can reduce the difficulty of assembling the handle assembly 100. The limit portion 21 cooperates with the limit matching portion 31 to prevent the push rod 30 from moving relative to the sliding member 20. In this way, the stability of the push rod 30 during the movement process can be improved, and the reliability of the overall structure of the handle assembly 100 can be enhanced.

[0054] Optionally, the fixing seat 10 is provided with a through hole, the push rod 30 is passed through the through hole, and the push rod 30 can perform linear reciprocating motion between the retracted position and the assisting position relative to the through hole.

[0055] The fixing seat 10 is provided with a through hole, and the push rod 30 moves between the retracted position and the assisting position through the through hole, thereby avoiding interference with the fixing seat 10 .

[0056] Optionally, combined Figure 4 As shown, one of the limiting portion 21 and the limiting matching portion 31 is a limiting boss 311 , and the other is a limiting slot 211 . The limiting boss 311 is engaged with the limiting slot 211 to prevent the ejector rod 30 from moving relative to the sliding member 20 .

[0057] By clamping the limiting boss 311 and the limiting slot 211, the push rod 30 and the sliding member 20 are limited, and a more accurate limiting effect can be achieved. The clamping method of the limiting boss 311 and the limiting slot 211 can not only prevent the push rod 30 from falling off and separating from the sliding member 20, but also prevent the push rod 30 from rotating relative to the sliding member 20, which can better improve the stability of the overall structure. At the same time, the cooperation between the limiting boss 311 and the limiting slot 211 can also simplify the assembly process.

[0058] Optionally, combined Figure 4 As shown, the sliding member 20 is provided with a receiving cavity 22 , and the end portion of the ejector rod 30 along the axial direction is inserted into the receiving cavity 22 to cooperate with the sliding member 20 .

[0059] The axial end of the push rod 30 can be inserted into the accommodating cavity 22 to cooperate with the sliding member 20. The accommodating cavity 22 provides additional support and positioning for the push rod 30, while also improving the compactness and space utilization of the overall structure.

[0060] The axial direction of the push rod is the length direction of the push rod 30 , and the radial direction of the push rod is the width direction of the push rod 30 .

[0061] Optionally, combined Figure 4 As shown, the limiting portion 21 includes a limiting slot 211, which is arranged on the side wall 221 of the accommodating cavity; the limiting matching portion 31 includes a limiting boss 311, which is arranged on the axial end of the push rod 30; wherein the limiting boss 311 and the limiting slot 211 are engaged with each other to prevent the push rod 30 from moving relative to the sliding member 20.

[0062] The limiting groove 211 is provided on the side wall 221 of the accommodating cavity, and the limiting boss 311 is provided on the end of the ejector rod 30 along the axial direction. In this way, when the limiting boss 311 and the limiting groove 211 are engaged, the radial protrusion of the ejector rod 30 can be limited. The ejector rod 30 can be more accurately limited. The engagement of the limiting boss 311 and the limiting groove 211 can prevent the ejector rod 30 from moving relative to the sliding member 20.

[0063] It can be understood that the limiting boss 311 can be arranged on the end surface 341 of the end of the push rod 30 in the axial direction, and the limiting boss 311 is arranged along the radial part of the push rod 30 and protrudes from the radial outer surface of the push rod 30. The limiting boss 311 can also be arranged on the radial side of the end, and the limiting boss 311 is arranged along the radial part of the push rod 30 and protrudes from the radial outer surface of the push rod 30.

[0064] Optionally, the sizes of the limiting boss 311 and the limiting slot 211 are matched.

[0065] The sizes of the limiting boss 311 and the limiting slot 211 are adapted to each other, so that the connection between the limiting boss 311 and the limiting slot 211 is more stable, thereby preventing the ejector rod 30 from moving relative to the sliding member 20 .

[0066] Optionally, the limiting boss 311 is adapted to the limiting slot 211 along the axial direction of the push rod 30 .

[0067] The limiting boss 311 is adapted to the limiting slot 211 in the axial direction of the push rod 30 , and can limit the push rod 30 from moving relative to the sliding member 20 in the axial direction of the push rod 30 .

[0068] Optionally, the limiting boss 311 is adapted to the limiting slot 211 in the circumferential direction of the push rod 30 .

[0069] The limiting boss 311 is adapted to the size of the limiting slot 211 along the circumferential direction of the push rod 30 , and can limit the push rod 30 from rotating relative to the sliding member 20 along the circumferential direction of the push rod 30 .

[0070] Optionally, combined Figure 4 As shown, a guide surface 32 is provided on the radial outer surface of the limiting boss 311 of the push rod 30 , and the guide surface 32 is inclined toward the axis of the push rod 30 along the direction in which the push rod 30 is inserted into the accommodating cavity 22 .

[0071] The limiting boss 311 is provided at the end of the push rod 30 in the axial direction. The limiting boss 311 at least partially protrudes from the outer surface of the push rod 30 in the radial direction, and can be engaged with the limiting slot 211 provided on the side wall 221 of the accommodating cavity. The limiting boss 311 is provided with a guide surface 32 on the outer surface of the push rod 30 in the radial direction. The guide surface 32 is inclined toward the axis of the push rod 30 along the direction in which the push rod 30 is inserted into the accommodating cavity 22, and can guide the insertion direction of the push rod 30, so that the push rod 30 can be inserted into the accommodating cavity 22 more smoothly and accurately.

[0072] Optionally, combined Figure 4 As shown, there are multiple limiting bosses 311, which are symmetrically arranged along the radial direction of the push rod 30; there are multiple limiting slots 211, which are symmetrically arranged along the radial direction of the accommodating cavity 22, and the multiple limiting bosses 311 and the multiple limiting slots 211 correspond one to one.

[0073] The one-to-one matching of the plurality of limiting bosses 311 and the plurality of limiting slots 211 can enhance the limiting fixing effect between the push rod 30 and the sliding member 20. The plurality of limiting bosses 311 are symmetrically arranged along the radial direction of the push rod 30, and the plurality of limiting slots 211 are symmetrically arranged along the radial direction of the accommodating cavity 22, which can improve the matching accuracy between the push rod 30 and the sliding member 20. At the same time, this symmetrical design can also simplify the assembly process.

[0074] Optionally, combined Figure 4 As shown, the push rod 30 includes a rod body 33 and a rod sleeve 34, and the rod sleeve 34 is sleeved on the outside of the rod body 33; the accommodating chamber 22 includes a first cavity 222 and a second cavity 223, and along the direction in which the push rod 30 is inserted into the accommodating chamber 22, the first cavity 222 and the second cavity 223 are arranged in sequence, the inner diameter of the first cavity 222 is adapted to the outer diameter of the rod sleeve 34, the inner diameter of the second cavity 223 is adapted to the outer diameter of the rod body 33, and a limiting surface 224 is formed between the first cavity 222 and the second cavity 223; wherein, the end of the push rod 30 along the axial direction includes the end of the rod body 33 and the end of the rod sleeve 34, when the push rod 30 is inserted into the accommodating chamber 22, the end of the rod body 33 is inserted into the first cavity 222 and the second cavity 223 in sequence, and the end of the rod sleeve 34 is inserted into the first cavity 222 and limited on the limiting surface 224.

[0075] The push rod 30 includes a rod body 33 and a rod sleeve 34. The rod sleeve 34 is sleeved on the outside of the rod body 33. This design not only improves the structural strength of the push rod 30, but also enhances the stability during movement. The accommodating chamber 22 includes a first cavity 222 and a second cavity 223. The inner diameter of the first cavity 222 is adapted to the outer diameter of the rod sleeve 34, which can provide more accurate positioning and support for the rod sleeve 34. The end of the rod body 33 can be inserted into the first cavity 222 and the second cavity 223 in sequence. The inner diameter of the second cavity 223 is adapted to the outer diameter of the rod body 33, which can achieve more accurate positioning and support for the rod body 33. At the same time, the inner diameter of the first cavity 222 is adapted to the outer diameter of the rod sleeve 34, and the inner diameter of the second cavity 223 is adapted to the outer diameter of the rod body 33, that is, the inner diameter of the first cavity 222 is larger than the inner diameter of the second cavity 223. This design forms a stepped limiting surface 224 between the first cavity 222 and the second cavity 223 . The end of the rod sleeve 34 is inserted into the first cavity 222 and can be limited to the limiting surface 224 , providing additional support and protection for the top rod 30 .

[0076] Optionally, combined Figure 4 As shown, the limiting boss 311 is arranged on the axial end face 341 of the rod sleeve 34, and the radial outer edge of the limiting boss 311 along the push rod 30 protrudes from the radial outer edge of the rod sleeve 34 along the push rod 30; the limiting groove 211 is arranged on the side wall of the second cavity 223, and the limiting boss 311 and the limiting groove 211 are clamped together to prevent the push rod 30 from moving relative to the sliding member 20.

[0077] The end of the rod sleeve 34 is inserted into the first cavity 222 and limited to the limiting surface 224, and the limiting boss 311 is provided on the end surface 341 of the rod sleeve 34 along the axial direction. When the push rod 30 is assembled to the sliding member 20, the limiting boss 311 located at the end surface 341 of the end of the rod sleeve 34 protrudes toward the direction of the second cavity 223, which can reduce the installation resistance. The outer edge of the limiting boss 311 along the radial direction of the push rod 30 protrudes from the outer edge of the rod sleeve 34 along the radial direction of the push rod 30, so that the limiting boss 311 can be stably engaged with the limiting groove 211 provided on the side wall 221 of the accommodating cavity.

[0078] Optionally, combined Figure 4 As shown, the inner surface of the limiting boss 311 along the radial direction of the push rod 30 is in contact with the outer surface of the rod body 33 .

[0079] The inner surface of the limiting boss 311 along the radial direction of the push rod 30 fits with the outer surface of the rod body 33, which can provide a limit between the rod body 33 and the rod sleeve 34 at the end of the push rod 30 in the radial direction of the push rod 30, thereby enhancing the stability of the overall structure.

[0080] Optionally, combined Figure 3-4As shown, the handle assembly 100 further includes a reset member 50 , which is disposed between the sliding member 20 and the fixing seat 10 to drive the push rod 30 to move from the assisting position toward the retracted position.

[0081] When the sliding member 20 moves toward the assisting position, the space between the sliding member 20 and the fixing seat 10 is reduced, and the reset member 50 located between the sliding member 20 and the fixing seat 10 is deformed. After the assisting is completed, the reset member 50 automatically recovers the deformation, and can drive the sliding member 20 to move, thereby driving the push rod 30 to move from the assisting position to the retracted position. In this way, the automation effect of the handle assembly 100 can be improved. The reset member 50 can be a spring.

[0082] Optionally, combined Figure 5-8 As shown, the handle assembly 100 also includes a handle 40, which is rotatably connected to the fixed base 10 via a rotating shaft 41 and can move between an open position and a closed position relative to the fixed base 10. The handle 40 cooperates with the sliding member 20 so that when the handle 40 moves toward the open position, it drives the sliding member 20 to move, thereby driving the push rod 30 to move toward the power-assisting position.

[0083] The handle 40 includes a first end 42 away from the rotating shaft 41 and a second end 43 close to the rotating shaft 41. The first end 42 of the handle 40 serves as an operable gripping end. The second end 43 of the handle 40 cooperates with the sliding member 20.

[0084] In the closed position, the first end 42 of the handle 40 abuts against the fixing base 10, and in the open position, the first end 42 of the handle 40 is separated from the fixing base 10. The handle 40 can assist in opening the door body 62 of the refrigeration device in the open position. The handle 40 is rotated to drive the push rod 30 to move toward the assisting position, and the lever principle is used to assist in opening the door, which can make the door opening process more labor-saving.

[0087] When the push rod 30 is in the assisting position, it abuts against the box body 61, and can realize the auxiliary door opening function. This design not only improves the convenience of door opening, but also reduces the extra force requirement caused by negative pressure, making the door opening process more labor-saving.

[0088] The sliding member 20 and the push rod 30 are separately provided. When assembling the handle assembly 100, the sliding member 20 is first installed in the fixing seat 10, and then the push rod 30 is inserted into the fixing seat 10 from the outside to cooperate with the sliding member 20, which can reduce the difficulty of assembling the handle assembly 100.
