[0002] The distribution cabinet is the final equipment of the power distribution system, which distributes the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. Figure 4 A common power distribution cabinet comprises a cabinet body 1, a cabinet door 2 which can be opened and closed is arranged on the front side of the cabinet body 1, and a glass 4 is arranged on the cabinet door 2 as an observation window. In the prior art, during production, an installation opening needs to be opened on the cabinet door 2, and then a cross section is used as Figure 5 The three-port sealing strip 3 (in the shape of a long strip and cut into a suitable length) shown in the figure surrounds the installation opening, wherein the four sides of the installation opening are inserted into the first accommodating portion 31, and then the four sides of the glass 4 are inserted into the second accommodating portion 32, and then the molding strip that matches the three-port sealing strip 3 is inserted into the molding strip accommodating portion 33. At this time, the glass 4 will not fall off. When the glass 4 is inserted into the second accommodating portion 32, although one side of the second accommodating portion 32 is easy to be bent outward due to the existence of the molding strip accommodating portion 33, during operation, one end of the glass 4 is generally first inserted obliquely into the second accommodating portion 32 on one side of the installation opening, for example Figure 4 The right side of the glass 4 (at this time, the left end of the glass 4 is a certain distance away from the cabinet door 2, and the right end is inserted into the second accommodating portion 32). At this time, the second accommodating portions 32 at the upper, lower and left sides of the installation opening are located on the side of the glass 4 close to the cabinet door 2. After that, one side of the second accommodating portions 32 at the upper, lower and left sides of the installation opening needs to be bent outward at the same time to place the other three sides of the glass 4 into the second accommodating portions 32. However, the sealing strip is relatively soft and it is impossible to bend one side of the second accommodating portion 32 outward at one point. Generally, only the part several centimeters near this point can be bent outward, resulting in the need for multiple people to bend the three sides out at the same time. Utility Model Content
