[0009] Preferably, the limiting mechanism includes a sliding rod and a spring, a push plate is slidably arranged inside the groove, the middle part of the push plate is fixedly sleeved with the outer wall of the lower end of the movable tube, sliding grooves are opened on both sides of the groove, the sliding rod is fixedly arranged inside the sliding groove, both ends of the push plate are movably sleeved with the corresponding sliding rod, the spring is movably sleeved on the rod wall of the sliding rod, and the two ends of the spring are respectively fixedly connected to the upper surface of the corresponding push plate and the inner wall of the sliding groove.

[0010] Preferably, a sealing ring is fixedly sleeved on the outer wall of the upper end of the movable tube, and the sealing ring contacts the upper side of the through hole.

[0011] Preferably, the upper end of the movable tube is sealed.

[0012] Preferably, the box body is a transparent box body.

[0013] Preferably, the outer wall of the movable tube is provided with a rubber sleeve.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model pushes the push plate upward so that the openings on both sides of the movable tube enter between the box body and the partition, and then injects heat-insulating water (ice water or hot water) into the movable tube. After it is filled, the push plate is released, and the spring force pushes the push plate to reset, so that the movable tube moves downward and resets, so that the sealing ring contacts the upper side of the through hole, thus sealing the through hole, and making the box body have a heat-insulating function, which can improve the use scenarios of the fresh-keeping box.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a corner plug negative pressure vacuum fresh-keeping box.

[0024] Reference Figure 1-3 A corner plug negative pressure vacuum fresh-keeping box, comprising a box body 1 and a box cover 2, the box cover 2 is arranged on the upper side of the box body 1, the box body 1 is a transparent box body, which is convenient for observing the inside of the box body 1, both ends of the box cover 2 are fixedly provided with a first buckle 3, both sides of the box cover 2 are provided with a second buckle 4, and the top of the box cover 2 is fixedly provided with a vacuum connection nozzle 5;

[0025] A partition 6 is fixedly provided at the inner bottom end of the box body 1, and the upper side of the partition 6 is fixedly connected to the inner wall of the box body 1. A groove is provided at the bottom of the box body 1, and a through hole is provided in the middle of the bottom of the groove. A movable tube 7 is inserted into the through hole, and openings are provided on both sides of the middle end of the movable tube 7.

[0026] Reference Figure 1-3 A limiting mechanism for limiting the movement of the movable tube 7 is arranged inside the groove, and the limiting mechanism includes a slide rod 10 and a spring 11. A push plate 9 is slidably arranged inside the groove, and the middle part of the push plate 9 is fixedly sleeved with the outer wall of the lower end of the movable tube 7. Slide grooves are opened on both sides of the groove, and the slide rod 10 is fixedly arranged inside the slide groove. Both ends of the push plate 9 are movably sleeved with the corresponding slide rod 10. The spring 11 is movably sleeved on the rod wall of the slide rod 10, and the two ends of the spring 11 are respectively fixedly connected with the upper surface of the corresponding push plate 9 and the inner wall of the slide groove.

[0027] Reference Figure 1-3 The outer wall of the upper end of the movable tube 7 is fixedly sleeved with a sealing ring 8, which contacts the upper side of the through hole to improve the sealing between the movable tube 7 and the through hole. The upper end of the movable tube 7 is sealed to prevent the insulation water from flowing out of the upper end of the movable tube 7 as much as possible. The outer wall of the movable tube 7 is provided with a rubber sleeve to improve the sealing between the movable tube 7 and the through hole.
