DETAILED DESCRIPTION

[0030] The following will be described in detail in combination with the accompanying Figures 1-3 The present application is further described in detail.

[0031] The present application discloses a high-sealing packaging paper box. Referring to Figure 1 A high-sealing packaging paper box comprises a box body 1, a cover body 2, a sealing member 3, and a plurality of oppositely arranged elastic clamping groove assemblies 4. The box body 1 is covered by the cover body 2. The box body 1 and the cover body 2 are sealed and fixed by the sealing member 3 and the elastic clamping groove assemblies 4.

[0032] Referring to Figure 1 and Figure 2 The end of the box body 1 and the cover body 2 is the upper end of the box body 1. The end of the cover body 2 and the box body 1 is the lower end of the cover body 2. The sealing member 3 is arranged at the outer side wall of the upper end of the box body 1. The sealing member 3 comprises a sealing frame 31 and a sealing gasket 32. The sealing frame 31 is adhered to the outer side wall of the upper end of the box body 1 by waterproof glue. The upper end surface of the sealing frame 31 is flush with the upper end surface of the box body 1.

[0033] Referring to Figure 2 A sealing groove 311 is formed at the upper end surface of the sealing frame 31. The sealing gasket 32 is adhered to the groove wall of the sealing groove 311 by waterproof glue. A sealing plug-in plate 21 is adhered to the position of the lower end surface of the cover body 2 which is aligned with the sealing groove 311 by waterproof glue. The sealing plug-in plate 21 is used to be inserted into the sealing groove 311 to seal the box body 1 and the cover body 2.

[0034] Referring to Figure 1 and Figure 2 A plurality of oppositely arranged elastic clamping groove assemblies 4 are arranged at the outer side wall of the sealing frame 31. In this embodiment, in order to stably cover the box body 1 and the cover body 2, a pair of oppositely arranged elastic clamping groove assemblies 4 are arranged at the left and right outer side walls of the sealing frame 31. Therefore, four sets of elastic clamping groove assemblies 4 are arranged in this embodiment.

[0035] Referring to Figure 2 and Figure 3, the elastic clamping groove assembly 4 comprises a clamping groove 41 and a pair of elastic clamping pieces 42 arranged at the inner side wall of the clamping groove 41, one end of the clamping groove 41 is integrally formed with the outer side wall of the sealing frame 31, the notch of the clamping groove 41 is located at the upper end face of the clamping groove 41, an opening 411 is formed at the end of the clamping groove 41 away from the outer side wall of the sealing frame 31, and a borrowed groove 412 is formed at the opposite inner side wall of the clamping groove 41, and one end of the elastic clamping piece 42 is welded with the groove bottom of the borrowed groove 412.

[0036] With reference to Figure 3 , the elastic clamping piece 42 comprises a clamping block 421 and a plurality of reset springs 422 distributed at equal intervals, one end of the reset spring 422 is welded with the end of the clamping block 421 facing the groove bottom of the borrowed groove 412, and the end of the reset spring 422 away from the clamping block 421 is welded with the groove bottom of the borrowed groove 412, in this embodiment, in order to enable the clamping block 421 to smoothly pop out of the borrowed groove 412, it is preferred that two reset springs 422 distributed at equal intervals are connected at the clamping block 421, and in order to prevent the clamping block 421 from being easily jammed when entering the borrowed groove 412, a chamfer 4121 is integrally formed at the notch edge of the borrowed groove 412.

[0037] With reference to Figure 1 , Figure 2 and Figure 3 , the clamping column 22 inserted into the clamping groove 41 and clamped with the clamping block 421 is adhered to the outer side wall of the cover 2 by waterproof glue, the end of the clamping column 22 away from the outer side wall of the cover 2 protrudes from the end of the clamping groove 41 provided with the opening 411, when the clamping column 22 abuts against the groove bottom of the clamping groove 41, the clamping column 22 abuts against the clamping block 421, so that the clamping column 22 is fixed between the groove bottom of the clamping groove 41 and the clamping block 421, and the two adjacent clamping columns 22 are integrally formed, so that the two adjacent clamping columns 22 integrally formed are in the shape of a handle, thereby facilitating the operator to disconnect or clamp the clamping column 22 in the clamping groove 41 with the clamping block 421.

[0038] The implementation principle of the high-sealing packaging paper box in the embodiment of the application is that when the sealing plug-in plate 21 is aligned with the sealing groove 311 and inserted into the sealing groove 311, the clamping column 22 also moves towards the groove bottom of the clamping groove 41, when the clamping column 22 abuts against the clamping block 421, under the extrusion of the clamping column 22, the clamping block 421 extrudes the reset spring 422 in the direction of the groove bottom of the borrowed groove 412, when the sealing plug-in plate 21 is completely inserted into the sealing groove 311, the clamping column 22 also abuts against the groove bottom of the clamping groove 41, at this time, the clamping block 421 is no longer extruded by the clamping column 22, and under the action of the reset spring 422, the clamping block 421 pops out in the direction away from the groove bottom of the borrowed groove 412 and clamps the clamping column 22 in the clamping groove 41 and abuts against the groove bottom of the clamping groove 41, thereby realizing the sealing property and stability when the box body 1 and the cover 2 are covered.

[0039] When the cover 2 needs to be removed from the box 1, a certain force is applied to the clamping column 22 and the clamping column 22 is pushed to move towards the direction of the slot opening of the clamping groove 41. At this time, the clamping block 421 moves towards the direction of the bottom of the slot 412 under the extrusion of the clamping column 22. When the clamping column 22 no longer extrudes the clamping block 421, the clamping block 421 is ejected from the slot 412 under the action of the reset spring 422. When the clamping column 22 moves out of the clamping groove 41, the sealing plug plate 21 also moves out of the sealing groove 311, that is, the cover 2 is removed from the box 1.

[0040] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
