Problems solved by technology

At the same time, for the safety of people on the road, a manhole cover should be installed on the shaft; however, some manhole covers do not have a locking mechanism, and cable theft incidents occur from time to time. Locking mechanism, but in order to keep the ground level, it is not suitable to lock the outside of the manhole cover, usually the locking mechanism is set inside the manhole cover
Since the locking mechanism is designed inside the manhole cover, when unlocking the manhole cover, it is not conducive to the unlocking operation of the staff, making it difficult to unlock the manhole cover
At the same time, from the appearance of the well cover, it is difficult to see whether the well cover is locked, and maintenance personnel often forget to lock or even close the well cover after laying or maintaining the cables in the well cover, resulting in the theft of the well cover and the cables in the well. broken things happen from time to time

Abstract

The invention relates to the technical field of manhole covers, in particular to a manhole cover lock and a manhole cover. The manhole cover lock comprises a locking plate. The locking plate cooperates with locking rod assemblies and a rotary assembly. The rotary assembly is provided with a driving part and a rotary part. Each locking rod assembly comprises a locking rod, a locking rod guide seatand a connecting part. The driving part is connected with the rotary part. The rotary part is connected with locking rods through corresponding connecting parts. The locking rods are driven to act byrotation of the rotary part. The locking rod guide seats are fixedly configured on the locking plate. The locking rods are slidingly connected to the locking rod guide seats. Meanwhile, the manhole cover with the manhole cover lock is provided. According to the manhole cover lock, the structure of the manhole cover lock is optimized; structural stability of the manhole cover lock is improved; thelocking rods are controlled to act through the driving part; and change of the state of the manhole cover lock is achieved.

Description

technical field [0001] The invention relates to the technical field of well covers, and more specifically, to a well cover lock and a well cover. Background technique [0002] With the development of urban construction, various pipelines are installed underground in the city for laying urban power supply cables and communication cables, and shafts are set at the intersection or important nodes of underground pipelines to facilitate the laying and maintenance of cables in the pipelines. At the same time, for the safety of people on the road, a manhole cover should be installed on the shaft; however, some manhole covers do not have a locking mechanism, and cable theft incidents occur from time to time. The locking mechanism should not be locked outside the well cover in order to keep the ground level, and the locking mechanism is usually arranged inside the well cover. Because the locking mechanism is designed inside the well cover, when the well cover is unlocked, it is not ...
