Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a fresh-keeping bag packaging box which is easy to draw out. Background Art

[0002] Fresh-keeping bags and fresh-keeping films are commonly used items in the kitchen. Currently, common fresh-keeping bags are generally made into long strips, with dotted lines on the fresh-keeping bags, and then rolled on a roller to form a roll. One or more roll-shaped fresh-keeping bags are placed in a paper fresh-keeping bag packaging box for sale and use. When using, take out the roll-shaped fresh-keeping bag, tear it off along the dotted lines of the fresh-keeping bag, and put the remaining roll-shaped fresh-keeping bag back into the fresh-keeping bag packaging box for storage. You can also simply stack the fresh-keeping bags together and put them in the fresh-keeping bag packaging box.

[0003] After searching, the Chinese patent publication number CN204568382U discloses a fresh-keeping bag packaging box, including a box body, characterized in that: one side edge of the upper surface of the box body is an open edge, and the open edge has two dotted line endpoints, two upper surface dotted lines extend from the two dotted line endpoints to the upper surface of the box body respectively, and two side dotted lines extend from the two dotted line endpoints to the side of the box body respectively, and the other two endpoints of the two side dotted lines are connected by a connecting dotted line or a connecting cut-off line; the above-mentioned side is provided with an insert at a position between the two side dotted lines, and the edge of the insert is an unclosed dotted line or cut-off line; the box body is provided with an inner side surface in the inner surface direction of the above-mentioned side surface, and the inner side surface is provided with an insert hole corresponding to the position of the insert. The above patent has the following shortcomings: In order to reduce the probability of tearing the fresh-keeping bag or the fresh-keeping film during the tearing process, a sawtooth piece is set on the top of the fresh-keeping box in the prior art to assist in tearing the fresh-keeping bag or the fresh-keeping film, but the sawtooth piece is generally sharp and fixed outside the box, so it may accidentally injure the user's hands, thus posing a safety hazard. In view of this, we propose a fresh-keeping bag packaging box that is easy to pull out. Utility Model Content

[0027] The telescopic mechanism 4 includes a sliding sleeve 41, a straight slot 42, an oblique slot 43, a first sliding column 44, and an inclined top block 45;

[0028] The sliding sleeve 41 is fixedly connected to the outer wall of the box body 1, and a straight card slot 42 is penetrated through the outer wall of the sliding sleeve 41, and an oblique card slot 43 is arranged on one side of the straight card slot 42. There are four straight card slots 42 and four oblique card slots 43. The interior of the sliding sleeve 41 is slidably connected to a first sliding column 44, and one side of the first sliding column 44 is fixedly connected to an oblique lift block 45, which is clamped in the interior of the straight card slot 42.

[0029] Specifically, the inclined ejector block 45 is connected by providing a straight clamping groove 42 and an inclined clamping groove 43 .

[0030] like Figure 3 As shown, the interior of the sliding sleeve 41 is slidably connected with a second sliding column 46, one side of the second sliding column 46 is fixedly connected to the serrated plate 5, the second sliding column 46 is arranged on the top of the first sliding column 44, and the second sliding column 46 is fixedly connected with dome blocks 47 around it. The four dome blocks 47 are respectively clamped in the inside of the four straight clamping grooves 42, and the dome blocks 47 are arranged on the top of the inclined top block 45.

[0031] like Figure 3 As shown, a round bracket 48 is fixedly connected to one side of the box body 1, one end of a spring 49 is fixedly connected to the inner wall of the round bracket 48, a disc 410 is fixedly connected to the top of the spring 49, the disc 410 is slidably connected to the inside of the round bracket 48, and the top of the disc 410 is rotatably connected to the bottom end of the second sliding column 46 via a bearing.

[0032] Specifically, the spring 49 is provided to drive the second sliding column 46 to rebound.

[0033] like Figure 4 As shown, a dustproof mechanism 6 is provided inside the box body 1, and the dustproof mechanism 6 includes a rack 61, and the rack 61 is fixedly connected to the bottom of the serrated piece 5. A horizontal axis 62 is rotatably passed through the inner wall of the box body 1 through a bearing, and a gear 63 is fixedly connected to the middle part of the horizontal axis 62, and the gear 63 is meshed with the rack 61.

[0034] like Figure 4 As shown, the other end of the horizontal shaft 62 away from the gear 63 is fixedly connected to a side plate 64 , and a dust cover 65 is fixedly connected to one side of the side plate 64 .

[0035] Specifically, the dustproof cover 65 is provided to prevent dust from forming on the fresh-keeping bag 3 exposed outside the box body 1 .

[0036] like Figure 1 As shown, an opening 2 is formed through the top of the box body 1 , and a fresh-keeping bag 3 is arranged inside the box body 1 .

[0037] Specifically, the fresh-keeping bag 3 is pulled out from the box body 1 through the opening 2 .

[0038] The working principle of the utility model is as follows:

[0039] After the sawtooth piece 5 is used to cut the fresh-keeping bag 3, the second slide column 46 is pressed downward to drive the dome block 47 to move downward. The dome block 47 moves downward to press the inclined top block 45 downward and compress the spring 49. When the inclined top block 45 moves downward to one side of the inclined slot 43, the dome block 47 will push the inclined top block 45 to the left and make it rotate to the left and fall. Under the action of the rebound force of the spring 49, it is stuck in the inclined slot 43. As a result, after the dome block 47 loses the supporting force of the inclined top block 45, it falls freely downward together with the second slide column 46 and the sawtooth piece 5. The sawtooth piece 5 moves, and the sawtooth piece 5 stops after falling to the top of the sliding sleeve 41, and the dome block 47 falls on one side of the inclined slot 43, thereby completing the storage of the sawtooth piece 5 into the box body 1. The sawtooth piece 5 moves downward and drives the rack 61 to move downward. The rack 61 moves downward and drives the gear 63 to rotate. The rotation of the gear 63 drives the horizontal axis 62 to rotate. The rotation of the horizontal axis 62 drives the side plate 64 and the dust cover 65 to rotate. The dust cover 65 rotates ninety degrees to form a flip and cover the top of the box body 1 to shield the dust from a part of the fresh-keeping bag 3 exposed on the box body 1.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
