Hole lid special for urban comprehensive pipe rack
The invention relates to the field of municipal facilities, and aims at providing a hole lid particularly suitable for being used for an urban comprehensive pipe rack. The hole lid special for the urban comprehensive pipe rack comprises a hole lid lock and a bouncing-off mechanism capable of automatically bouncing a hole lid body after the hole lid lock is unlocked. The bouncing-off mechanism comprises the hole lid body and a hold lid ring, and the hole lid ring is hinged to the hole lid body. A bouncing-off spring is arranged between the hole lid body and the hole lid ring. When the hole lid body is closed to the hole lid ring, the bouncing-off spring is compressed. The hole lid lock comprises a lock cylinder located on the hole lid body, the spring bolt portion of the lock cylinder is in a kidney shape, a spiral spring is further arranged on the inner side of the hole lid body, one end of the spiral spring is fixed, and the other end of the spiral spring is connected with a lock rod penetrating the interior of the spiral spring. One end of the lock rod makes contact with the spring bolt portion, and the other end of the lock rod is matched with a lock hole in the hole lid ring. During locking, the spring bolt portion pushes the lock rod to be inserted into the lock hole. In the opening process, the spiral spring drives the lock rod to retreat from a lock hole driving part. The hole lid can be effectively prevented from being stolen, and meanwhile more time and labor are saved in the opening process.
