[0002] Dentures are what people often call "false teeth". Just like "false legs" and "false limbs" are called "artificial limbs", "dentures" mean teeth that fulfill "duties" for humans. In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient himself, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient. Dentures are usually stored in denture packaging boxes.

[0003] The seal of the traditional denture packaging box is usually connected by a buckle and a card block directly through a snap connection, which is easy to fall off and bounce open when hit, so that the denture contained inside has a certain risk of damage. At the same time, after a certain period of use, the aging of the buckle greatly reduces the tightness of the snap connection. Therefore, the utility model proposes a drying device and an organic fertilizer production equipment to solve the above problems Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealing mechanism, including a packaging box, wherein the packaging box is provided with a lower telescopic sleeve groove at four top corners of the outer upper end, and buckle grooves are provided at the left and right ends of the inner side of the lower telescopic sleeve groove; fixed limit platforms are fixedly connected to the left and right sides of the upper end surface of the lower telescopic sleeve groove; a sealing cover, wherein the sealing cover is fixedly connected to a telescopic sleeve rotating shaft at both side ends of the four top corner bosses on the outer side, and an elastic fastening device is sleeved on the outer side of the telescopic sleeve rotating shaft.

[0006] Preferably, the elastic fastening device includes a rotating telescopic sleeve, a spring groove is opened on the lower end surface of the rotating telescopic sleeve, a fastening spring is fixedly connected to the inner end of the spring groove, an elastic telescopic buckle is fixedly connected to the end of the fastening spring, and the elastic telescopic buckle can be correspondingly inserted in the buckle groove.

[0007] Preferably, both sides of the upper end plate of the rotating telescopic sleeve are provided with rotating shaft grooves, and the rotating shaft of the telescopic sleeve is sleeved in the rotating shaft grooves.

[0008] Preferably, the sealing cover is provided with upper telescopic sleeve grooves at four top corners of the side surface.

[0009] Preferably, the lower edge line of the inner end of the rotating telescopic sleeve is rounded.

[0010] Preferably, the sealing cover is provided with a rounded corner at a position corresponding to the rotating telescopic sleeve.

[0011] A denture packaging box, wherein the above-mentioned sealing mechanism is used.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides an elastic fastening device, so that the packaging box is not easily separated from the sealing cover when it is hit, and its sealing performance can still be maintained, and the sealing fastness will not be affected even after long-term use.

DETAILED DESCRIPTION

[0018] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: a sealing mechanism, including a packaging box 1, wherein the packaging box 1 is provided with lower telescopic sleeve grooves 3 at four vertex corners of the upper outer side, and buckle grooves 4 are provided at the left and right ends of the inner side of the lower telescopic sleeve groove 3; the left and right sides of the upper end surface of the lower telescopic sleeve groove 3 are fixedly connected with fixed limit platforms 5; a sealing cover 2, wherein the sealing cover 2 is fixedly connected with telescopic sleeve rotating shafts 8 at both side ends of the four vertex corner bosses on the outer side, and an elastic fastening device is sleeved on the outer side of the telescopic sleeve rotating shaft 8.

[0021] Embodiment 2

[0022] The elastic fastening device includes a rotating telescopic sleeve 6, a spring groove 11 is provided on the lower end surface of the rotating telescopic sleeve 6, a fastening spring 12 is fixedly connected to the inner end of the spring groove 11, and an elastic telescopic buckle 7 is fixedly connected to the end of the fastening spring 12. The elastic telescopic buckle 7 can be correspondingly inserted into the buckle groove 4, and rotating shaft grooves 10 are provided on both sides of the upper end plate of the rotating telescopic sleeve 6. The telescopic sleeve rotating shaft 8 is sleeved in the rotating shaft groove 10. The fastening spring 12 is always in a stretched state, and the elastic telescopic buckle 7 can be pulled out. When the tension is released, it can be pulled back by the fastening spring 12.

[0023] Embodiment 3

[0024] The sealing cover 2 is provided with upper telescopic sleeve grooves 9 at four top corners of the side surface, which are used to cooperate with the elastic telescopic buckle 7 sleeved in the rotating telescopic sleeve 6 to correspond to the packaging box 1.

[0025] Embodiment 4

[0026] The lower edge line of the inner end of the rotating telescopic sleeve 6 is rounded, and the sealing cover 2 is rounded at a position corresponding to the rotating telescopic sleeve 6. The rotating telescopic sleeve 6 can rotate within a certain range around the rotating shaft 8 of the telescopic sleeve.
