In the embodiment, the handle 2 is arranged on the left and right sides of the box 1, which is convenient for both hands to hold when moving the refrigerator. The fixed base 21 is connected with the box 1 by means of bolts, and is used to fix the turnable handgrip 22. The turnable handgrip 22 includes a grip 221, a first turning member 222 and a second turning member 223. The grip 221 is used for holding, and the turning part is rotationally connected with the fixed base 21. In order to avoid noise generated by shaking the turnable handgrip 22 and the box 1 during the moving process of the refrigerator, a spring 23 is arranged between the turnable handgrip 22 and the fixed base 21, and the elastic force of the spring 23 makes the turnable handgrip 22 close to the box 1, so as to avoid the above defects.


In the embodiment, two ends of the grip 221 are provided with a first recess 500, side wall of the second accommodation cavity 300 is provided with a protrusion 600, the protrusion 600 is locked in the first recess 500 to prevent the grip 221 from rotating relative to the first turning member 222 and the second turning member 223. The grip 221 is connected with the first turning member 222 and the second turning member 223 through bolts. In order to avoid the bolt loosening caused by the rotation of the grip 221, a mechanical connection between the protrusion 600 and the first recess 500. When the turnable handgrip 22 is rotated, the grip 221 rotates simultaneously with the first turning member 222 and the second turning member 223. The protrusion 600 may be a cuboid or other shapes, and the shape of the first recess 500 is compatible with the protrusion 600.


In the embodiment, the lower part of the connecting column 200 is provided with an inner limiting protrusions 700 and a second recess 800. The fixed base 21 is further provided with an outer limiting protrusion 213, the outer limiting protrusions 213 corresponds to the position of inner limiting protrusions 700; the first accommodation cavity 211 is provided with limiting plates at intervals. Both the inner limiting protrusions 700 and the outer limiting protrusions 213 are arc-shaped protrusion. When the connecting column 200 and the springs 23 of the first turning member 222 and the second turning member 223 are fixed in the first accommodation cavity 211, the outer limiting protrusion 213 and the inner limiting protrusion 700 are in the same plane. When the handle 2 rotates, the inner limiting protrusion 700 also rotates. When the handle 2 is rotated to abut against the outer limiting protrusion 213, the handle 2 is subject to resistance, which limits the rotation angle of the handle 2 and prevents the handle from being damaged due to excessive rotation angle.


In the embodiment, a horizontal connection end 231 and a vertical connection end 232 are extended out of two ends of the spring 23; the horizontal connection end 231 is abutted against the limiting plates, vertical connection end 232 is accommodated in the second recess 800. Multiple limiting plates are provided in the first accommodation cavity 211, intervals between different limiting plates form different limiting intervals. When the horizontal connection end 231 is placed in different limiting intervals, the twist angle is different, and the spring force is also different, so the spring force of spring 23 can be adjusted. That is, when the handle 2 is close to the box 1 when it is not operated, the elastic force should not be too large or too small. If it is too large, it needs a large force to pull up the handle 2. If the force is too small, the handle 2 can not be close to the box 1. During the movement, it will shake and make noise. It can be adjusted to the appropriate limit range according to the use condition. The second recesses 800 is used to accommodate and fix the vertical connection end 232 of the spring 23, so that the spring can be twisted to produce elastic force.


In the embodiment, the grip 221 is a plated steel pipe or a stainless steel pipe. Mobile refrigerators often encounter water when they are in use. In order to avoid wet hands from contacting the grip 221 and rusting, the material of the grip 221 is set as plated steel or stainless steel.


In the mobile refrigerator having built-in handles of the present application, the springs are provided at the handle, and the handle is adhered to the box by means of the elasticity of the springs, and thus does shake during movement; multiple limiting plates form different intervals, the elasticities of the springs are different when the springs are in different intervals, so as to adjust the tightness of the springs, i.e., the closeness of the handle adhered to the box is adjusted; by means of the abutting of inner limiting protrusions and outer limiting protrusions, the turning angle of the handle is limited, thereby preventing the handle from being damaged due to too large turning angle.


The above content is only a prefer embodiment of the present application. For ordinary technical personnel in the field, according to the idea of the present application, many changes can be made in the specific implementation mode and application scope.
