[0032] Further, in order to enable the public to have a better understanding of the utility model, in the following detailed description of the utility model, some specific details are described in detail. The present utility model can also be completely understood without the description of these details for those skilled in the art.

[0033] Please see Figure 1 And Figure 2The embodiment provides a plastic shell sealing structure, which comprises a first shell 1 and a second shell 2.

[0034] The first shell 1 is provided with an opening, and the opening end of the first shell 1 is provided with a glue storage groove 11, which is arranged along the internal contour line of the first shell 1; that is, the glue storage groove 11 is arranged in a circle, and the glue is added into the glue storage groove 11 in advance during sealing, so that the second shell 2 can be mounted on the first shell 1.

[0035] The inner side of the first shell 1 is provided with a plurality of fixed clamping grooves 12, and the second shell 2 is provided with a fixed buckle 21 corresponding to the clamping groove; the fixed buckle 21 can be clamped in the fixed clamping groove 12 and close the opening of the first shell 1; that is, when the second shell 2 is buckled on the first shell 1, the fixed buckle 21 is first clamped in the clamping groove of the first shell 1, and then the lower surface of the second shell 2, that is, the surface where the fixed buckle 21 is arranged, extrudes the glue in the glue storage groove 11, so that the sealing and fixing are completed.

[0036] In the application, the fixed clamping groove 12 of the first shell 1 and the fixed buckle 21 of the second shell 2 are designed to ensure that the two shell parts have enough pressing force after being glued, so that the shell parts can be kept in close connection during the glue drying process and the installation process, thereby preventing the occurrence of installation problems.

[0037] In addition, the glue storage groove 11 is arranged on the glue bonding surface during gluing, which can ensure the continuity of the glue bonding surface and increase the bonding area of the glue, thereby improving the sealing effect.

[0038] In other schemes, the fixed clamping groove 12 comprises a clamping groove upper segment 121, a clamping groove middle segment 122 and a clamping groove lower segment 123; the clamping groove upper segment 121 is a rectangular groove, the clamping groove middle segment 122 is a quarter of a cylinder, and the arc surface faces the opening of the first shell 1, and the clamping groove lower segment 123 is a rectangular groove. The clamping groove upper segment 121 is a rectangular groove, which can form a cavity with the side stop surface of the fixed buckle 21, and the glue flows into the cavity after being poured and can seal the interlocking structure after drying; the lower surface of the clamping groove middle segment 122 is a plane, when the fixed buckle 21 approaches the fixed clamping groove 12, the fixed claw part of the fixed buckle 21 elastically deforms in the direction away from the clamping groove middle segment 122 through the arc-shaped guide of the clamping groove middle segment 122, and then falls into the lower surface of the clamping groove middle segment 122, so as to realize clamping; the clamping groove lower segment 123 is a rectangular groove, and mainly functions to accommodate the fixed claw of the buckle, and is slightly higher than the height of the fixed claw in size for reservation.

[0039] In other schemes, the fixed buckle 21 includes a buckle upper section 211, a buckle middle section 212 and a buckle lower section 213; the buckle upper section 211 is a fixed claw part, which is a right trapezoid; the buckle middle section 212 is a connecting plate; and the buckle lower section 213 is a supporting leg, which is a triangular structure. The fixed claw part of the upper section is provided in a right trapezoid shape, so that the fixed claw part is thicker as a whole, which can ensure that the fixing force is large enough after fixing, and the bottom edge of the right trapezoid of the fixed claw part is opposite to the lower plane of the middle section 122 of the clamping groove after clamping. The buckle lower section 213 is a supporting leg, which is a triangular structure, and is more stable. In addition, the area of the supporting leg is larger than the area of the upper section of the fixed groove, so that it can cover the area. The benefit is that after gluing, when the upper cover is installed, glue will not leak into the internal cavity of the shell through the upper section of the fixed clamping groove 12.

[0040] In other schemes, the glue storage groove 11 is a semicircular groove. By setting it as a semicircular groove, the overall size ensures that there is enough glue on the glue bonding surface, and the appropriate spacing between the fixed clamping grooves 12 on the first shell 1 is also met.

[0041] In other schemes, a gap is left between the glue storage groove 11 and the fixed clamping groove 12. By setting a reasonable gap, it can avoid the glue flowing into the glue storage groove 11 when adding glue in the glue storage groove 11.

[0042] In other schemes, the fixed clamping grooves 12 are symmetrically distributed in two groups with the center axis at the lower edge of the first shell 1, symmetrically distributed in two groups with the center axis at the middle of the side edge, and symmetrically distributed in two groups with the center axis at the upper edge. Through the division, the fixing can be well performed. At the same time, the upper edge and the lower edge are closer to the turning angle position of the shell in position, which aims to ensure that the turning angle position can be installed in place.

[0043] In other schemes, the inner bottom surface of the second shell 2 is provided with a plurality of reinforcing ribs 22. The reinforcing ribs 22 can increase the overall strength.

[0044] In other schemes, the fixed buckles 21 are connected by the reinforcing ribs 22. The reinforcing ribs 22 can further strengthen the bottom strength of the fixed buckles 21.

[0045] In other schemes, the opening end of the first shell 1 is provided with a mounting groove 13, and the glue storage groove 11 and the fixed clamping groove 12 are arranged in the mounting groove 13. It should be understood that the mounting groove 13 is used to mount the second shell 2, and through the mounting groove 13, the second shell 2 and the first shell 1 are installed, and the external zero difference of the second shell 2 and the first shell 1 is achieved.

[0046] In other schemes, the glue storage groove 11 is located on the side close to the outer surface of the first shell 1 of the mounting groove 13. By setting the glue storage groove 11 outward as much as possible, the sealing effect can be better.

[0047] The sealing structure of the plastic shell can ensure that the first shell and the second shell have sufficient pressing force after being glued, thereby eliminating the adverse problems caused by improper installation.

[0048] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, without departing from the concept of the present application, a number of simple deductions or substitutions can be made, and any equivalent changes or modifications made in accordance with the spirit and essence of the present application should be covered within the protection scope of the present application.
