[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts are within the protection scope of the utility model.

[0026] Please refer to Figures 1-2 The utility model provides a blind box shell with waterproof and dustproof functions, which comprises a box body 1 and a cover body 2 covering the box body 1.

[0027] The box body 1 comprises a bottom wall 11 and a side wall 12 extending upward from the edge of the bottom wall 11;The top of the side wall 12 is provided with a first protrusion 121, and an elastic sealing ring 3 is sleeved outside the first protrusion 121;The outer side of the side wall 12 is provided with a second protrusion 122;

[0028] The cover body 2 comprises a cover plate 21 and a cover wall 22 extending downward from the edge of the cover plate 21, and the cover wall 22 comprises a first part 221 and a second part 222 connected with the first part 221, and the second part 222 is provided with a first recess 2221 matched with the elastic sealing ring 3;The inner side wall 12 of the second part 222 is provided with a second recess 2222 matched with the second protrusion 122;

[0029] When the box body 1 and the cover body 2 are covered, the second protrusion 122 is buckled with the second recess 2222, the elastic sealing ring 3 is embedded into the first recess 2221, and the sealing connection between the box body 1 and the cover body 2 is realized.

[0030] Wherein, the application sets the first protrusion 121 on the top of the side wall 12 of the box body 1, and sets the elastic sealing ring 3 outside the first protrusion 121, and combines the first groove 2221 design of the cover body 2, when the box body 1 and the cover body 2 are closed, the elastic sealing ring 3 is embedded in the first groove 2221 and elastically deformed, so as to realize close fitting, prevent moisture and dust from entering the inside of the blind box, and effectively protect the internal articles from being polluted by moisture and dust.

[0031] In an embodiment according to the application, the outer diameter of the elastic sealing ring 3 is greater than the inner diameter of the first groove 2221, and the elastic sealing ring 3 and the first groove 2221 are in interference fit. Wherein, the outer diameter of the elastic sealing ring 3 is greater than the inner diameter of the first groove 2221, so that it is elastically deformed when it is embedded in the first groove 2221, thereby realizing interference fit; through the interference fit design, the elastic sealing ring 3 generates a certain pressure in the first groove 2221, further enhancing the sealing performance; and the gap is completely filled, which can effectively prevent moisture or dust from penetrating through the gap, improving the protection performance of the blind box.

[0032] In an embodiment according to the application, the longitudinal section of the elastic sealing ring 3 is in inverted U-shaped structure. Wherein, the inverted U-shaped structure provides a larger contact area and elastic deformation space, and when the box body 1 and the cover body 2 are combined, the elastic sealing ring 3 can better adapt to the shape of the groove, ensuring the sealing effect.

[0033] In an embodiment according to the application, the thickness of the second part 222 of the cover wall 22 is greater than the thickness of the first part 221. Wherein, the second part 222 is the key area cooperating with the elastic sealing ring 3 and the second protrusion 122, and the thickening design can improve the strength and rigidity of this area, so that it is not easy to deform when contacting the box body 1, ensuring the stability of the sealing effect; the thickening design of the second part 222 can also improve the impact resistance, avoiding the cover body 2 from being warped or deformed under external force, thereby further enhancing the waterproof and dustproof performance of the blind box shell.

[0034] In an embodiment according to the application, the material of the elastic sealing ring 3 is elastic rubber. Wherein, the elastic rubber has excellent resilience and sealing performance, and can maintain good sealing effect in the process of repeated opening and closing, prolonging the service life of the blind box shell; the elastic rubber also has strong weather resistance and aging resistance, and is not easy to lose elasticity due to long-term contact with moisture or high temperature, thereby improving the protection ability of the blind box shell in harsh environment.

[0035] In an embodiment according to the application, the box body 1 and the cover body 2 are made of metal material or waterproof plastic. The metal material has high rigidity and strength, can effectively resist external force deformation, and thus enhances the protection performance of the blind box shell. The waterproof plastic material, such as ABS or polycarbonate (PC), has light weight, low cost, excellent moisture resistance and chemical corrosion resistance, and can further improve the waterproof and dustproof ability of the blind box.

[0036] In an embodiment according to the application, the blind box shell has a whole "convex" structure. The "convex" structure makes the blind box shell more stable in structure, the nesting design between the box body 1 and the cover body 2 can further reduce the seam width and improve the sealing performance, and the structure design also facilitates user operation, so that the cover body 2 can be more easily embedded or separated from the box body 1, and the user experience is improved. In addition, the "convex" structure makes the blind box more stable during stacking or transportation, and is not easy to be loosened due to vibration or shaking.

[0037] It should be noted that the contents not described in detail in the specification belong to the prior art known to those skilled in the art, and will not be described here.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
