[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1 Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a sealing mechanism for an insulated refrigerator, comprising: Box 1; The flipping mechanism 2 is located on the outside of the box body 1. The flipping mechanism 2 includes internal threaded columns 201 symmetrically arranged inside the box body 1. A handle 204 is movably installed on the outside of the internal threaded columns 201. A threaded knob 202 adapted to the internal threaded columns 201 is provided on one side of the handle 204. An arc-shaped block 203 is provided inside the handle 204. An arc-shaped groove 205 is opened on the top of the arc-shaped block 203. A protrusion 208 adapted to the arc-shaped groove 205 is installed on the inner surface of the handle 204.

[0024] Specifically, both sides of the housing 1 are provided with mounting grooves that are adapted to the inner threaded post 201. The inner threaded post 201 is fixedly installed inside the mounting groove. The handle 204 is rotatably connected to the outside of the inner threaded post 201. The threaded knob 202 rotates and engages with the inner threaded post 201. Through the action of the threaded knob 202, after the threaded knob 202 is fully engaged with the inner threaded post 201, it can fix the handle 204 in the flipped position and has the function of controlling the rotation of the handle 204.

[0025] Specifically, the outer surface of the handle 204 has an opening that is adapted to the arc-shaped block 203. The arc-shaped block 203 is slidably connected to the inner surface of the handle 204. The protrusion 208 is movably engaged inside the arc-shaped groove 205. When the handle 204 is rotated around the inner threaded post 201 to a vertical position, the handle 204 is engaged in the arc-shaped groove 205, so that the handle 204 remains vertical without external force, so that the operator can quickly lift the box 1. When the handle 204 is rotated to a position that is adapted to the arc-shaped groove 205 at the opening, the arc-shaped groove 205 can be disengaged from the opening.

[0026] Specifically, the inner threaded post 201 has several top beads 207 arranged circumferentially inside, and a first spring 206 is installed on the outer surface of the top beads 207. A sliding groove adapted to the top beads 207 is opened on one side of the inner threaded post 201, and the top beads 207 are slidably connected inside the sliding groove. The threaded knob 202, on the side opposite to the inner threaded post 201, has several arc-shaped slots circumferentially arranged to adapt to the top beads 207. Under the action of the first spring 206, the corresponding top beads 207 are pushed towards the threaded knob 202, pushing the top beads 207 into the corresponding arc-shaped slots of the threaded knob 202. Several top beads 207 are pushed into the corresponding arc-shaped slots of the threaded knob 202 by the corresponding first spring 206. After the threaded knob 202 and the inner threaded post 201 are fully engaged, an outward force is applied to the threaded knob 202 to prevent the threaded knob 202 from rotating in the opposite direction and to improve the stability of the handle 204.

[0027] Furthermore, manually rotate the textured knob 202 counterclockwise until the handle 204 can rotate around the inner threaded post 201. Rotate the handle 204 around the inner threaded post 201 to a vertical position. At this time, the handle 204 drives the protrusion 208 to engage in the corresponding arc-shaped groove 205. Rotate the textured knob 202 clockwise. The textured knob 202 presses the handle 204 against one side of the box body 1. After the textured knob 202 is fully tightened, under the action of several first springs 206, the corresponding top bead 207 is pushed outward, so that the top bead 207 pushes into the textured knob 202, fixing the textured knob 202 in this state. The box body 1 can then be lifted and transported manually using the handle 204.

[0028] Example 2 Reference Figure 5 and Figure 6 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The snap-fit ​​mechanism 3 is set on the top of the box 1. The snap-fit ​​mechanism 3 includes a sealing cover 301 hinged to the top of the box 1. A cross slider 302 is symmetrically arranged inside the sealing cover 301. A snap block 306 adapted to the box 1 is arranged on one side of the cross slider 302.

[0029] Specifically, the sealing cover 301 has a symmetrical cross groove on one side that is adapted to the cross slider 302, and a sliding hole on one side of the cross groove that is adapted to the locking block 306. The outer surface of the housing 1 has a slot that is adapted to the locking block 306. The locking blocks 306 are slidably connected inside the sliding hole and the slot. The arc block 203 is installed at the center of one side of the sealing cover 301. Under the action of the locking block 306, the sealing cover 301 can be tightly combined with the housing 1. After the sealing cover 301 is tightly covered around the hinge at the top of the housing 1, the locking block 306 is inserted into the slot of the housing 1 to fix the sealing cover 301 to the top of the housing 1.

[0030] Specifically, a push rod 303 is installed on one side of the cross slider 302, a limit plate 304 is provided on one side of the push rod 303, a second spring 305 is installed on one side of the limit plate 304, and a circular groove adapted to the limit plate 304 is opened on one side of the cross slide groove. The limit plate 304 is slidably connected inside the circular groove. Under the action of the second spring 305, a pushing force is applied to the limit plate 304 in the direction of the cross slider 302. With the assistance of the push rod 303 and the cross slider 302, the locking block 306 is stably locked in the slot of the box 1, and the sealing cover 301 is fixed to the top of the box 1.

[0031] Furthermore, after the sealing cover 301 is flipped around the hinge to the top of the box 1, the sealing cover 301 is completely attached to the top of the box 1. At this time, the locking block 306 is pushed into the slot of the box 1. Under the action of the second spring 305, the limiting plate 304 is pushed towards the cross slider 302. The limiting plate 304 pushes the push rod 303, and the push rod 303 pushes the cross slider 302. With the assistance of the cross slider 302, when the locking block 306 is not subjected to external force, the cross slider 302 is always in the slot of the box 1, so that the sealing cover 301 can be quickly fixed to the top of the box 1.

[0032] Working principle: Manually rotate the threaded knob 202 counterclockwise until the handle 204 can rotate around the inner threaded post 201. Rotate the handle 204 around the inner threaded post 201 to the rear of the box 1. At this time, the opening of the handle 204 rotates to the arc block 203. Manually push the two cross sliders 302 towards each other. The cross sliders 302 drive the corresponding locking blocks 306 out of the box 1. Then, flip the sealing cover 301 upward around the hinge. The sealing cover 301 drives the two arc blocks 203 to pass through the opening of the handle 204. After opening the sealing cover 301, place the items to be refrigerated into the inner cavity of the box 1. After that, manually flip the sealing cover 301 in the opposite direction around the hinge and place it on the top of the box 1. At this time, the locking blocks 306 are pushed into the slot of the box 1. Under the action of the second spring 305, the limiting plate 304 applies a pushing force towards the cross slider 302, limiting the movement. Plate 304 applies a pushing force to push rod 303, which in turn applies a pushing force to cross slider 302. With the assistance of cross slider 302, when the locking block 306 is not subjected to external force, cross slider 302 remains in the slot of housing 1, thus quickly fixing the sealing cover 301 to the top of housing 1. When housing 1 needs to be lifted, handle 204 is rotated around inner thread post 201 to a vertical position. At this time, handle 204 drives protrusion 208 to lock. Insert the corresponding arc-shaped groove 205 and rotate the textured knob 202 clockwise. The textured knob 202 presses the handle 204 to one side of the box 1. After the textured knob 202 is fully tightened, under the action of several first springs 206, the corresponding top ball 207 is pushed outward, so that the top ball 207 pushes into the textured knob 202, fixing the textured knob 202 in this state. The box 1 can then be lifted and moved manually through the handle 204.
