The invention relates to a municipal road well lid. The municipal road well lid comprises a well body and a lid body arranged at a well mouth, wherein the well mouth is provided with a locking grooveused for locking the lid body; a vertical wall is vertically arranged downwards in the circumferential direction of the bottom of the lid body; the vertical wall is located in the locking groove; a lifting mechanism is arranged in the locking groove; the lifting mechanism makes contact with the bottom of the vertical wall; a plurality of locking columns are further arranged in the locking groove;the locking columns are distributed in the radial direction of the lid body; the locking columns are connected into the sidewall of the locking groove through a slide mechanism; and a strip hole is formed in the vertical wall. According to the municipal road well lid, through the cooperation of the slide mechanism and the lifting mechanism, locking and ascending detachment can be flexibly realizedfor the lid body; and moreover, switch parts of the slide mechanism and the lifting mechanism are located in a locking cover, the lock cover can be opened only by working personnel with dedicated keys, and then the slide mechanism and the lifting mechanism are used. The municipal road well lid is convenient to use, incapable of being randomly detached, and safe and reliable.

The invention discloses a resource locking method, a computing device and a computer storage medium. The method includes: for any task, determining resource information to be accessed by the task; obtaining a path corresponding to the resource according to the resource information to be accessed; querying Whether the number of sub-paths under the path in the coordination service system is less than the access restriction threshold, if so, record the current version information of the resource, generate the creation command and version update command for creating the sub-path corresponding to the resource and task in the coordination service system, and The creation command and version update command are submitted to the coordination service system, so that the coordination service system determines whether to execute the creation command and version update command according to the judgment result of whether the version conflicts; if the coordination service system successfully executes the creation command and version update command, then the task is The resource is locked successfully. Through the above method, any number of tasks can lock the resource, which improves the flexibility of locking the resource.

A user authenticating apparatus in accordance with the present invention stores user information where identification information to identify each of a plurality of users and biometric information of each user are associated with each other, acquires identification information of the user, when the user starts to use a predetermined target, authenticates each user using the acquired identification information and the stored user information, as first authentication, stores the identification information of the user whose first authentication is succeeded as success information, acquires the biometric information of the user, and authenticates each user using the acquired biometric information and the biometric information corresponding to the identification information of the users stored as the success information among the stored biometric information, as second authentication.

The invention relates to an upper guide plate frame fast exchanging device of a large caliber punch in the field of seamless pipe production device which includes the upper guide plate frame for fixing the upper guide plate; the upper guide plate is arranged in a guide frame arranged on a stander through the matching of a slide block; the side surface of the guide frame is provided with a laterallocking device; the front side and the back side of the upper guide frame are respectively and vertically provided with a cylinder supported on a balancing oil cylinder on the stander; the piston rodof the balancing oil cylinder is arranged at the lower end of the two sides of the upper guide plate frame; the two sides of the upper guide plate frame are provided with two guide slots; the guide slots are provided with a sliding locking frame in clearance fit; the back side of the sliding locking frame is provided with a sliding drive mechanism; a screw the lower end of which is butted on the upper end of the upper guide plate frame is arranged in the sliding locking frame; a nut is arranged outside the screw; a worm wheel is fixedly arranged outside the nut; the side surface of the worm wheel is engaged and provided with a worm which is horizontally arranged on the sliding locking frame; the worm and a locking motor are connected in a transmission way. The upper guide plate frame fastexchanging device of a large caliber meets the production demands for the seamless pipe with large scale and large group interval through quickly and entirely exchanging the upper guide plate frame.

The invention relates to a natural gas measuring instrument based on the internet of things. The instrument comprises a main body, a connecting pipe, a card reading mechanism and a central control mechanism, wherein the card reading mechanism comprises a card reader and a locking mechanism; the locking mechanism comprises a locking frame, a locking component and an unlocking component; a locking unit comprises a spring, a push plate, a push rod, a locking door frame and a hinge pin; the unlocking unit comprises an operation block, a first connecting rod and a second connecting rod; and a working power module comprises a working power circuit. In the natural gas measuring instrument based on the internet of things, a radio frequency card can be preserved reliably and hermetically by the locking mechanism; meanwhile, by the unlocking component, flexible unlocking of the radio frequency card is realized, so that the practicability of a detecting instrument is improved; moreover, in the working power circuit, the stable output of supply voltage can be realized through the feedback collection of input voltage and output voltage, which is performed by the integrated circuit; and the working stability and reliability of the detecting instrument is improved.
