DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5A metal sheet metal shell that can be sealed and installed includes a bottom shell 1. The outer walls on both sides of the bottom shell 1 are provided with a snap-in groove 5. A W-shaped sealing strip 3 is embedded and installed in the snap-in groove 5 through the upper shell 2. The upper shell 2 is covered and installed on the upper part of the bottom shell 1, and sealing columns 31 are provided on both sides of the W-shaped sealing strip 3. A support frame 9 is embedded and installed inside the W-shaped sealing strip 3. Elastic springs 91 are connected on both sides of one end of the support frame 9. The elastic springs 91 extend into the sealing column 31, and the sealing column 31 is squeezed and contacted with the inner wall of the upper shell 2.

[0022] Furthermore, side panels 101 are installed on both sides of the bottom shell 1, and the upper shell 2 is installed on the outer side of the side panels 101. A pair of conical blocks 6 are installed on the bottom of the upper shell 2. When the upper shell 2 is connected to the bottom shell 1, the conical blocks 6 are squeezed and contacted with the side panels 101, so that the side panels 101 are tilted and squeezed and contacted with the inner wall of the upper shell 2 to improve the tightness of the connection.

[0023] Furthermore, the inner wall side and top surface of the upper shell 2 are symmetrically provided with installation grooves 8, and a W-shaped sealing strip 3 is embedded in the installation groove 8. A pair of extrusion columns 12 are provided on one side of the W-shaped sealing strip 3. The extrusion columns 12 are limitedly installed in the installation groove 8 and are in extrusion contact with the inner wall of the installation groove 8.

[0024] Furthermore, a plurality of mounting holes 4 are provided at corresponding positions in the upper shell 2 and the clamping slot 5 .

[0025] Furthermore, an extrusion cavity 10 is opened in the middle of the W-shaped sealing strip 3 , a spring 11 is installed on one side of the inner wall of the extrusion cavity 10 , and the other end of the spring 11 is connected to the middle of the support frame 9 .

[0026] Furthermore, a through hole is opened in the middle of the W-shaped sealing strip 3 , and the through hole coincides with the mounting hole 4 .

[0027] In this embodiment, the W-shaped sealing strip 3 provided on the inner wall of the upper shell 2 is aligned with the snap-in groove 5 opened on the outer wall of the bottom shell 1 and snapped in. At this time, the upper shell 2 is slowly pressed down along the snap-in groove 5 so that it gradually covers the upper part of the bottom shell 1. When the upper shell 2 completely covers the outer wall of the bottom shell 1, the upper shell 2 is pressed down so that the sealing strip at the top inside it is completely snapped into the groove. At this time, the bottom shell 1 and the upper shell 2 are further connected by driving fasteners into the mounting holes 4. When the joint between the two gradually shrinks, the sealing columns 31 provided on both sides of the W-shaped sealing strip 3 expand outward and fill the joint, and the joints at the side and top are filled firmly.

[0028] In actual use, as the gap between the shells shrinks, the spring 11 set inside the W-shaped sealing strip 3 is squeezed, and squeezes the support frame 9 and elastic spring 91 on one side, causing the two to deform, and then synchronously drive the external sealing strip body and sealing column 31 to move.

[0029] In actual use, the W-shaped sealing strip 3 can be pulled outward later and removed from the mounting groove 8 provided on the inner wall of the upper shell 2 to replace a new sealing strip, thereby ensuring the service life of the sealing strip and improving the sealing performance.

[0030] The W-shaped sealing strips 3 are arranged in a rectangular shape on both sides of the inner wall of the upper shell 2 , and two W-shaped sealing strips 3 are provided on the top of the upper shell 2 , and the sealing strips on the side and top surfaces are connected to each other.

[0031] In the present invention, a W-shaped sealing strip 3 is provided at the connection between the upper shell 2 and the bottom shell 1. As the fasteners connect the two tightly, the sealing columns 31 provided at both ends of the W-shaped sealing strip 3 are moved by the elastic spring 91 and expanded, and the joints between the plates are filled, thereby ensuring their absolute sealing. At the same time, during later use, the W-shaped sealing strip 3 can still be freely disassembled and replaced through the installation groove 8, which not only ensures the sealing performance of the sheet metal shell, but also effectively ensures the service life of the W-shaped sealing strip 3 and improves the sealing effect.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
