The utility model discloses a high -tension connecting device of power transformer relates to power transformer installation tool technical field, including installation cylinder and wire pressing subassembly, installation cylinder and wire pressing subassembly swing joint, wire pressing subassembly includes wire pressing board, buckling plate, installation cover, installation rod and spring, and wire pressing board has two and rotates the connection, and the installation shaft of wire pressing board is fixedly connected with installation rod, and installation rod and installation cover swing joint, and the top of installation cover is through the installation cylinder and is fixedly connected with buckling plate, and the cooperation of wire pressing board, buckling plate, installation cover and installation rod and press the effect of double compression of sleeve is realized to this scheme, improves the stability to cable connection end copper wire, utilizes the cooperation of transition strip, connecting block and locking sleeve can be connected with cable shell stably, makes whole and cable shell connect together, avoids the cable copper wire connection end under the gravity and appears the situation of loose connection, and simultaneously buckling plate, press the waterproof dustproof effect of each junction of sleeve and protective sleeve is improved.

This utility model relates to the field of wireless communication antenna technology, and in particular to a waterproof 5G mushroom-shaped antenna, comprising a lower cover and an upper cover. The lower cover and the upper cover are assembled by fitting together to form a sealed outer shell structure. Multiple mounting holes are evenly distributed circumferentially along the edge of the lower cover. Multiple connecting posts are evenly distributed circumferentially inside the upper cover, and multiple supporting posts are evenly distributed circumferentially inside the lower cover. By setting an outer waterproof ring and an inner waterproof ring on the lower cover to form an annular sealed interlayer, and cooperating with the annular pressure plate at the bottom of the upper cover embedded in this interlayer, a double compression sealing structure is formed, thereby significantly improving the dustproof and waterproof capability at the joints, enabling the overall protection level to reach IP68 standard.

The utility model discloses a sealed moistureproof heat preservation box, including box and box cover, the top installation box cover of box, the bottom of box cover is equipped with sealing washer, the top of box is set up sealing groove, the sealing washer is inlayed in the inside of sealing groove, the side of box cover is equipped with elastic plate, the side of elastic plate is equipped with link plate, the inside of elastic plate is seted up the clamping groove, the side of box cover is equipped with fixed plate and clamping block, the inside of fixed plate is equipped with the shaft sleeve. This sealed moistureproof heat preservation box, through the inside inlaying clamping block of elastic plate, and install spherical handle in the inside of fixed plate, the stability of box cover is convenient to improve, and staff first assembles box cover and box, and the clamping groove of elastic plate inside is inlaid in the outside of clamping block, and rotates spherical handle and installed it in the inside of limiting plate, because being equipped with double compression structure, in this way, box cover can be compressed in the top of box, and the stability of sealing is stronger when using.
