[0031] Based on the above structural features of the present application, the implementation methods of the present application are further described:
[0032] Reference Figures 1 to 11 The present embodiment provides a handle for a movable refrigerator, including a mounting plate 1 and a handle assembly 2 disposed in a receiving cavity 01 of a refrigerator housing 0. The refrigerator housing 0 is formed by a plurality of shell plates joined together by bolts or welding, and the side wall of the housing 0 is recessed inward to form the receiving cavity 01, which is used to provide a storage space for the handle assembly 2, and the mounting plate 1 is used to connect the housing 0 and the handle assembly 2.
[0033] Reference Figure 1 to Figure 3 The mounting plate 1 is fixedly connected to the inner wall of the accommodating cavity 01; the handle assembly 2 is rotatably connected to the mounting plate 1. When the handle assembly 2 is rotated inwardly until the handle assembly 2 is placed in the accommodating cavity 01, the movable refrigerator as a whole has a smaller space occupied, which is convenient for storage; when the handle assembly 2 is rotated outwardly until the handle assembly 2 tilts outwardly, the outer end of the handle assembly 2 has a larger gripping space, which is convenient for users to grasp.
[0034] Reference Figure 2-Figure 3 The handle assembly 2 includes a connecting rod 21, a connecting member 22 and a rotating shaft 23. One end of the connecting member 22 is vertically connected to the end of the connecting rod 21 (for example, fixedly connected by bolts), and the other end of the connecting member 22 is provided with an axial hole, which is sleeved and rotatably connected with the rotating shaft 23; the rotating shaft 23 is connected to the mounting plate 1 through a bearing. An elastic layer is provided on the surface of the connecting rod 21, and the elastic layer is used to improve the gripping touch of the user; the elastic layer is for example a sponge layer, a rubber layer, etc. The elastic layer is in a cylindrical structure and sleeved on the surface of the connecting rod 21.

When the first limiting column 101 abuts against the end of the first limiting groove 221 or the second limiting column 102 abuts against the end of the second limiting groove 222, the rotation angle of the handle assembly 2 is limited. For example, the angle between the two ends of the first limiting groove 221 is 100°, the angle between the two ends of the second limiting groove 222 is 100°, and the angle between the first limiting column 101 and the second limiting column 102 is 100°, so that the rotation angle of the handle assembly 2 is limited within 100°.

[0040] Reference Figure 5 to Figure 7 A third limiting column 103, a fourth limiting column 104 and a cushion block 33 are provided between the mounting plate 1 and the support plate 3. The third limiting column 103 is a hollow straight cylinder structure, and the third limiting column 103 is installed between the mounting plate 1 and the support plate 3 by a fourth bolt 31, and the two end surfaces of the third limiting column 103 are respectively abutted and fixed with the mounting plate 1 and the support plate 3; the fourth limiting column 104 is a hollow straight cylinder structure, and the fourth limiting column 104 is installed between the mounting plate 1 and the support plate 3 by a fifth bolt 32, and the two end surfaces of the fourth limiting column 104 are respectively abutted and fixed with the mounting plate 1 and the support plate 3; the cushion block 33 is installed between the mounting plate 1 and the support plate 3 by a sixth bolt, and the two side surfaces of the cushion block 3 are respectively abutted and fixed with the mounting plate 1 and the support plate 3.
[0041] Reference Figure 3 and Figure 5 The cushion block 33 is placed above the rotating shaft 23, and the lower surface of the cushion block 33 is arranged horizontally; when the connecting member 22 rotates to abut against the lower surface of the cushion block 33, it can be used to assist in bearing the load, reduce the pressure borne by the first limiting column 101 and the second limiting column 102, thereby improving the service life of the utility model.

The end of the first limiting column 101 away from the first limiting rod 11 is fixedly connected to the mounting plate 1 by bolts, and the end of the second limiting column 102 away from the second limiting rod 12 is fixedly connected to the mounting plate 1 by bolts; the end of the first limiting rod 11 away from the first limiting column 101 is fixedly connected to the mounting plate 1 by bolts, and the end of the second limiting rod 12 away from the second limiting column 102 is fixedly connected to the mounting plate 1 by bolts.

When the handle assembly 2 rotates around the rotating shaft 23, the first sleeve 111 and / or the second sleeve 121 rolls along the side wall of the connecting member 22 to reduce friction, thereby ensuring the smooth rotation of the handle assembly 2. Stop rings are respectively provided at both ends of the first sleeve 111, and the stop rings are fixedly connected to the first limiting rod 11 (for example, heat shrink connection); stop rings are respectively provided at both ends of the second sleeve 121, and the stop rings are fixedly connected to the second limiting rod 12 (for example, heat shrink connection).
[0044] Reference Figure 10-11 , since the first limit rod 11 and the first limit column 101 are connected in a U shape, and the first limit rod 11 and the first limit column 101 are connected in a U shape, fillets / chamfers will be generated at the connection position between the first limit column 101 and the first limit rod 11, the bending position of the first limit rod 11, the connection position between the second limit column 102 and the second limit rod 12, and the bending position of the second limit rod 12, so that the gap between the first limit rod 11 and the side wall of the mounting plate 1 is greater than the thickness of the connecting member 22, and the gap between the second limit rod 12 and the side wall of the mounting plate 1 is greater than the thickness of the connecting member 22, further leading to the hidden danger of shaking of the connecting member 22; the first sleeve 111 is sleeved on the first limit rod 11 and crimped on the side wall of the mounting plate 1, and the second sleeve 121 is sleeved on the second limit rod 12 and crimped on the side wall of the mounting plate 1, which can avoid shaking of the connecting member 22 and improve the rotation stability and service life of the handle assembly 2.

The connecting rod 21, the connecting member 22, and the rotating shaft 23 are connected in a rectangular shape.
[0046] The connecting member 22, the mounting plate 1, the rotating shaft 23, the first limiting column 101, the second limiting column 102, the first limiting rod 11, the second limiting rod 12, and the supporting plate 3 are all made of metal materials (such as stainless steel) to increase the load-bearing capacity of the utility model.
[0047] The utility model uses the accommodating cavity 01 to store the handle assembly 2, which reduces the volume of the movable refrigerator after packaging and is convenient for storage and transportation; the mounting plate 1 is used to realize the rotation connection of the handle assembly 2, so as to realize the flexible rotation of the handle assembly 2; the first limiting column 101 and the second limiting column 102 have excellent bearing capacity, and bear the force on the handle assembly 2 when moving / lifting the movable refrigerator; and solves the problem that the movable refrigerator handle in the traditional technology cannot take into account both excellent space occupation and bearing capacity. At the same time, the first sleeve 111 and the second sleeve 121 are pressed against the side wall of the mounting plate 1, which can prevent the connecting member 22 from shaking, and improve the rotation stability and service life of the handle assembly 2.
