Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by people familiar with the technology, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the present invention does not have the substantial significance in the technology, and any structure modification, ratio relationship change or size adjustment should still fall within the scope which can be covered by the technical content disclosed by the present invention without affecting the efficacy which can be produced by the present invention and the achievable purpose. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Referring to fig. 1 to 3, a sealing and leakage-proof packing box cover includes a cover body 1, a buckling flange 11 is provided at the outer side of the cover body 1, and the cover body 1 is buckled on the box body 2 to make the buckling flange 11 hermetically connected with an outer flange 21 of the box body 2. The other structures of the cover body 1 and the box body 2 are similar to the prior packing box, and are not described in detail here.

The fastening flange 11 includes an inner fastening edge 12, a sealing edge 13 is provided on the inner fastening edge 12, a protruding portion 14 protruding toward the inner side of the outer flange 21 is provided on the sealing edge 13, and the sealing edge 13 and the protruding portion 14 are in sealing contact with the outer flange 21 in the vertical direction and form a double seal. The sealing structure arranged at two intervals with the outer convex edge 21 is realized through the sealing edge 13 and the convex part 14, and the occurrence of matching leakage phenomenon caused by process forming reasons is reduced.

The portion of the sealing edge in sealing contact with the side of the outer flange 21 forms a first sealing point 3. The sealing edge 13 is vertically arranged. As shown in fig. 2. Because the outer flange 21 is of a right-inclined structure, the vertical seal is generally in contact seal with the convex part on the left side of the outer flange 21, the contact area of the two is small, but the pressing force is large, and the sealing effect is good. Here as the first sealing point 3, a sealing action is achieved.

The contact of the convex surface of the convex portion 14 with the side surface of the outer flange 21 forms the second sealing point 4. The boss 14 is an arc-shaped boss structure. The arc-shaped protruding structure contacts with the inclined part of the lower side of the outer convex edge 21, the protruding surface is arc-shaped protruding, and the lower side part of the outer convex edge 21 is tightly pushed to serve as a second sealing point 4. The sealing surfaces of the two are small in area, but the pressing force is large, so that the assembly gap can be further reduced, and a good sealing effect is realized.

If the liquid in the box body 2 leaks, a small amount of leaked liquid needs to pass through the second sealing point 4 first, and due to the fact that the second sealing point 4 and the first sealing point 3 are spaced, the liquid cannot directly permeate into the second sealing point 4, but is accumulated between the second sealing point 4 and the first sealing point 3 or falls along the first sealing point 3. Under the condition that the leaked liquid is slightly more, the second sealing point 4 plays a role in sealing again, and the liquid is prevented from leaking out of the box body 2 through the second sealing point 4.

The projection 14 has a beveled guide edge 15 below, and the outer flange 21 is guided by the beveled guide edge 15 into the snap-fit bead 11. When the cover body 1 is installed on the box body 2, the guiding bevel edge 15 plays a role in guiding, the guiding bevel edge 15 moves downwards along the left side face of the outer convex edge 21, the cover body 1 is convenient to press downwards, and the cover body 1 can be installed perfectly under the condition of labor saving.

The fastening flange 11 further comprises an outer flange 16, the inner wall of the outer flange 16 is provided with a plurality of protruding fasteners 17, and the protruding fasteners 17 are in fit clamping connection with the lower outer edge of the outer flange 21. The raised buttons 17 are long arc-shaped raised buttons, and the raised buttons 17 are uniformly distributed along the inner wall of the outward flange 16 at intervals. The raised buttons 17 are located inside the grooves 18 on the flanges 16. The existing box cover only has the inward convex groove 18 on the outward flanging 16 to be clamped with the box body 2, thereby realizing the fixed connection of the cover body 1. This kind of connection structure can appear the phenomenon of bullet lid, and buckles through increasing inside bellied arc arch in the inboard of flanging 16, and the arc arch is buckled and is followed the cooperation joint with outer chimb 21's lower outer edge, restricts lid 1 in vertical direction, improves joint strength between the two, avoids lid 1 to play the lid.

In embodiment 2, referring to fig. 4, the sealing edge 13 is inclined toward the outer flange 21, the contact area between the inclined sealing edge 13 and the outer flange 21 is large, the sealing surface is larger, and a good sealing effect is also achieved. The rest is the same as example 1.

Be different from prior art, the utility model discloses sealed leak protection packing lid can realize the sealed between lid and the box body through the seal structure that the twice interval set up, and sealed effect is better, avoids the technology shaping reason to lead to the emergence of leakage phenomenon.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
