Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 6, the in-vehicle refrigerator with a double sealing structure in this embodiment includes a cabinet 1, a cabinet cover 2, and a locking assembly 3.

Wherein, case lid 2 one side is rotated and is set up on box 1, and the opposite side of case lid 2 is provided with locking Assembly 3, is formed with refrigeration chamber 11 on the box 1, is formed with the interior seal bulge loop 211 that extrudes together with refrigeration chamber 11 inside wall on case lid 2, is formed with the external seal recess 212 that is located the outside of interior seal bulge loop 211 on case lid 2, is provided with the outer seal circle that compresses tightly on the box 1 terminal surface in the external seal recess 212.

Furthermore, in order to improve the sealing effect of the outer sealing ring, a clamping groove for clamping the outer sealing ring is formed on the end face of the box body 1. Or, a pressing convex strip 12 for pressing the outer sealing ring may be formed on the end face of the box body 1, and the outer sealing ring is pressed by the pressing convex strip 12, so that the outer sealing ring is extruded and deformed, and the whole outer sealing groove 212 can be filled.

In addition, in the embodiment of the present invention, the case cover 2 includes a cover plate 21 and an outer cover 22, the inner sealing convex ring 211 and the outer sealing groove 212 are formed on the cover plate 21, the outer peripheral wall of the cover plate 21 is formed with a bending portion 213 bending upwards, the inner side wall of the outer cover 22 is formed with a spacing strip 221, and the lower end of the spacing strip 221 is provided with a spacing slot for clamping the bending portion 213.

Furthermore, in the embodiment of the utility model provides an, locking Assembly 3 includes retaining member 31, axle 32 and torsional spring, be formed with the mounting groove 214 that is used for installing retaining member 31 on the case lid 2 opposite side, seted up the perforation on the both sides wall of mounting groove 214, the axle hole has been seted up at retaining member 31 back, retaining member 31 lower part is formed with joint portion 311, be formed with the joint groove 13 with joint portion 311 looks adaptation on the box 1, axle 32 passes the perforation of case lid 2 and the axle hole that draws of retaining member 31, the torsional spring housing is located and is formed with the torsion of joint portion 311 joint in joint groove 13 on axle 32.
