The beneficial effects of the utility model are as follows: the fixing hole can clamp the clamping portion of the wire by the flat portion, and the wire is firmly fixed so that the wire cannot rotate. At the same time, the two baffles on the wire are clamped on both sides of the housing, which can also effectively ensure that the limit cannot be displaced, thereby ensuring the stable position of the wire, and will not deform during long-term use, thereby increasing its service life. However, the prior art still has defects:

[0004] 1. The shell and the top cover used in the prior art are connected by a fixed rack and a ring groove. When the shell and the top cover are disassembled, all the racks around the circumference need to be pulled out from the inside of the ring groove, which is not convenient for disassembly and assembly.

[0005] 2. The shell and the top cover used in the prior art are connected by a fixed rack and an annular groove. After many times of disassembly and assembly, the rack and the annular groove are easily unable to be connected due to wear, and the durability is poor. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide a power adapter installation shell.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a power adapter installation shell, including a bottom shell, a mounting frame is fixedly connected to the bottom end of the bottom shell, a baffle is arranged on the upper side of the outside of the mounting frame, a sealing groove is opened on the upper side of the outside of the bottom shell, a rotating hole is opened at the bottom end of the bottom shell, a disc is arranged inside the rotating hole, movable rods are arranged on both sides of the front and back of the bottom shell, movable holes for matching the movable rods are opened on both sides of the front and back of the mounting frame, L-shaped connecting rods are fixedly connected to the ends of the movable rods that are close to each other, a plurality of evenly distributed toggle grooves for matching the connecting rods are opened on the upper side of the disc, T-shaped locking blocks are fixedly connected to the ends of the movable rods that are away from each other on the outside of the mounting frame, springs for matching the locking blocks and the mounting frame are sleeved on the outside of the movable rods, locking grooves for matching the locking blocks are opened on both sides of the front and back of the bottom shell, an upper cover is arranged on the upper side of the outside of the bottom shell, a sealing block for matching the sealing groove is fixedly connected to the lower end of the upper cover, and locking holes for matching the locking blocks are opened on both sides of the front and back of the sealing block.

[0008] As an improvement, a knob is fixedly connected to the lower side of the disk, and the outer side of the disk is rotatably connected to the inner side of the rotating hole.

[0009] As an improvement, a cross-shaped fixing block is fixedly connected to the lower side of the baffle, and a limiting groove used in conjunction with the movable rod is opened on the lower side of the fixing block.

[0010] As an improvement, a plurality of evenly distributed heat dissipation holes are provided on the upper side of the outer portion of the upper cover, and a sealing cover used in conjunction with the heat dissipation holes is rotatably connected to the upper side of the outer portion of the upper cover.

[0011] As an improvement, the other end of the connecting rod connected to the movable rod is inserted into the toggle groove, and the sealing cover is semicircular.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention uses a disk arranged at the bottom end of the bottom shell to toggle the connecting rod connected to the movable rod through the toggle groove, so that the four T-shaped locking blocks can synchronously approach or move away from each other to lock and unlock the bottom shell and the upper cover, and a spring is used between the installation frame and the locking block to automatically squeeze the locking block outward, which is convenient for locking and can quickly disassemble and assemble the shell.

[0013] 2. The utility model utilizes a T-shaped locking block to be stuck in the locking hole provided on the upper cover to achieve locking. When locking and unlocking, the friction between the locking block and the locking hole is small, the wear is small during use, and the utility model is more durable.
