The invention provides an electric pressure cooker realizing simple and convenient cover opening operation. The electric pressure cooker comprises a cooker body, a cooker cover and a fastener, wherein the fastener comprises a movable clamp arranged on the cooker cover and a buckle piece positioned on the cooker body, the cooker cover is buckled to the cooker body through the fastener, the cooker cover comprises a lock cover and a liner, the lock cover rotates to realize the locking and unlocking of the lock cover and the cooker body, the cooker cover is further provided with a rotation base and a shift fork part linked to the rotation base, the rotation base drives the lock cover to rotate through the shift fork part, the rotation base is provided with a trigger part, the liner is provided with a rotation drive part positioned between the trigger part and the movable clamp, the rotation base drives the lock cover to rotate to the unlocking position, meanwhile, the trigger part triggers the rotation drive part, the rotation drive part pushes the movable clamp, and the movable clamp is separated from the buckle piece, so that the cooker cover is opened. According to the electric pressure cooker, the shift fork part drives the lock cover to rotate, when the lock cover rotates to the unlocking position, cooker teeth are staggered from cover teeth, meanwhile, the movable clamp is triggered, then the cooker cover is opened, the cooker cover is opened only through one rotation step, and thus the use by a user is facilitated.

The invention relates to a timepiece comprising a drive module (10), a dial (12) comprising a central opening (13), an hours wheel (14) passing through the central opening (13) of the dial (12) and rotationally driven by the drive module (10), and a dial attachment device. The attachment device comprises a retaining tube (15) arranged around the hours wheel (14) and mechanically connected to the drive module (10). The retaining tube (15) is configured to come to bear against the dial (12) or against a dial support (17) to which the dial is fixed.

The invention relates to a sliding way type releasing bridge plug. A long sliding way and a short sliding way are formed in the outer wall of the lower portion of an upper center pipe, the short sliding way is obliquely arranged and is communicated with the long sliding way into a V shape, the bottom end of the long sliding way directly penetrates through the bottom of the upper center pipe, and the end of a sliding pin is arranged in the short sliding way and can slide in the long sliding way and the short sliding way. According to the sliding way type releasing bridge plug, the defects of releasing achieved by shearing a pin under the condition of high pressure or heavy-load lifting are overcome, the principle that pin suspension is fixed through heavy load, and releasing is achieved without a power sliding way is adopted, it is ensured that an anchor is released at the right position, the situation that releasing is conducted too early is avoided, water plugging and well shutting efficiency is improved, and unnecessary waste is avoided.

The invention provides a double-dispensing-head and double-station dispensing device, aiming at overcoming the defect that workpieces in the prior art are not unified, thus the glue cannot be dispensed to the preset position. The double-dispensing-head and double-station dispensing device comprises a conveying device, a station, a station locating mechanism, a detection device, a dispensing head and a double-station glue valve mechanism, wherein the dispensing head is arranged on the double-station glue valve mechanism; one end of the station is provided with a push cylinder; the conveying device is arranged at the other end of the station; the station locating mechanism is fixed on the station; the station comprises a first station and a second station; the detection device comprises a first detection device, a second detection device, a third detection device and a fourth detection device; the dispensing head comprises a first dispensing head and a second dispensing head which are symmetrically arranged on the double-station glue valve mechanism; the first detection device and the second detection device are in induction connection with the first station; the third detection device and the fourth detection device are in induction connection with the second station.

An application method and management system of permanent-immediate integration in expressway information construction. The application method includes: 1) in the project design stage, determine the project and application parameters of permanent-interconnection; 2) in the bidding stage, arrange the equipment for later-stage electromechanical engineering Bidding is carried out in the early stage of civil engineering, and the ownership of Yonglin combined equipment is stipulated in the bidding documents, and management methods for Yonglin combined equipment are formulated; 3) In the construction stage, the mechanical and electrical engineering department installs highway information equipment and enters the use of equipment 4) In the operation and maintenance phase, the operation and maintenance unit receives the data and equipment of Yonglin combination, counts the use and maintenance of the equipment, determines the specific installation location of the equipment, and puts the equipment into use. The management system includes equipment parameter confirmation module, information collection module, remote communication module, central management server, SQL Server database, measurement and payment module, remote computer and mobile terminal. The invention saves project cost.
