Mobile refrigerator having built-in handles

A mobile refrigerator having built-in handles, comprising:

• a box and handles, wherein side portions of the box are provided with recesses for accommodating the handles each handle comprises a fixed base, a turnable handgrip, and two springs;
• the fixed base is connected to the box by bolts;
• the turnable handgrip is turnably connected to the fixed base by the two springs;
• two ends of the fixed base are provided with a first accommodation cavity and first bolt holes;
• the fixed base is fixed on the box by bolts through the first bolt holes;
• the turnable handgrip comprises a grip, a first turning member and a second turning member respectively connected to both ends of the grip;
• both ends of the grip are provided with second bolt holes;
• connecting columns are provided on top of the first turning member and the second turning member, second accommodation cavities are provided on bottom of the first turning member and the second turning member;
• a third bolt hole is provided on bottom of each second accommodation cavity, the grip is connected to the first turning member and the second turning member separately by bolts;
• each spring is sleeved on the connecting column that face each other, the connecting column and the spring are both accommodated in the first accommodation cavity, making the first turning member and the second turning member turnably connected to the fixed base separately;
• wherein each of the connecting column of the first turning member and the second turning member is provided with an inner limiting protrusion and a second recess at lower part of the connecting column to correspond to a position of an outer limiting protrusion provided on the fixed base;
• and
• wherein the inner limiting protrusion extends circumferentially upward from a lower portion of the connecting columns;
• wherein the inner limiting protrusion is configured to engage with the outer limiting protrusion formed in the first accommodation cavity, the outer limiting protrusion and the inner limiting protrusion are arc-shaped protrusions that engage with each other such that:
• when the connecting column and the spring of the first turning member and the second turning member are fixed in the first accommodation cavity, the outer limiting protrusion and the inner limiting protrusion are in a same plane, and
• when the handle is rotated to abut against the outer limiting protrusion, the handle is subject to resistance so as to limit rotational angle of the handle and prevent the handle from damage due to excessive rotational angle.
