The invention provides an automatic door lock, comprising a lock shell having a dead bolt hole molded with dead lock hole; a lock assembly installed on the lock shell panel and the lock shell bottom panel corresponding to a molded lock installation hole; a bolt mechanism installed in the lock shell capable of moving along the direction perpendicular to the lock shell panel; a locking control mechanism for controlling the bolt in the bolt mechanism extruding from and retracting into the panel; and a bolt locking mechanism matched with the door handle operating mechanism. The automatic door lock implements engagement and disengagement of the stop member with a fixed stripe and a movable stripe by coupling of the fixed and the movable stripe, the stop member is capable of engaging with the fixed and the movable stripe at different positions, incomplete unlocking operation due to extrusion of a bolt partially retracted into the shell is prevented.

The invention provides an interlocking assembly and a cooking utensil. The interlocking assembly comprises a door hook, an interlocking support, an interlocking rotary block, a positioning torsional spring and a buffer device. According to the scheme, the buffer device is additionally arranged on the basis of an existing interlocking assembly, a door body is in an open state, the interlocking rotary block is in an unlocking position, and the door hook and the interlocking rotary block are separated; and in the door closing process, the door hook abuts against the interlocking rotary block and then pushes the interlocking rotary block to rotate, the buffer device applies resistance to the interlocking rotary block in the process that the interlocking rotary block rotates to a locking position from the unlocking position, momentum of the door body is reduced so that impact to a box body front plate can be reduced when the door body is closed, and thus the problem that paint of the box body front plate or the door body is peeled off due to the fact that door closing force of a user or a tension hinge is too large is solved.

The invention relates to a lock tongue locking mechanism matched with a door handle manipulation mechanism, which comprises a locking part of a lock tongue member, a door handle mounting hole, a shaft sleeve, a mandrel of the door handle manipulation mechanism and a contilever plate, wherein the door handle mounting hole is molded in the position of a door lock shell corresponding to the door handle; the shaft sleeve of which the sidewall is provided with a through groove is arranged in the door handle mounting hole; the mandrel of the door handle manipulation mechanism can axially slide, is rotatably arranged inside the shaft sleeve and a lug boss; the mandrel is provided with a shifting block radially extending; the shifting block is suitable for sliding in the through groove; the extending length of the shifting block is greater than the thickness of the shaft sleeve and the sidewall of the lug boss; the contilever plate is pivotally arranged on a journal of the shaft sleeve through a shaft sleeve mounting hole molded on the contilever plate; the arched part of the shaft sleeve mounting hole corresponding to the shifting block is provided with a shifting groove; and the shifting block is embedded into the shifting groove. The lock tongue locking mechanism solves the technical problems that parts of the lock body are overmany and have small strength and the requirement of mounting precision is high, and is particularly suitable for an inserted core lockset.

The invention discloses a braking mechanism for a baby carriage. The braking mechanism comprises a wheel shaft, a pair of braking hubs, a pair of pedal pieces and a linkage pipe, wherein the braking hubs are fixed inside wheels of the baby carriage; the wheel shaft is mounted between a pair of wheels of the baby carriage; the pedal pieces are sleeved on the wheel shaft; a plurality of bulges, which encircle the wheel shaft and are distributed at intervals, are arranged on the braking hubs; a blocking slot is formed between adjacent bulges; a braking assistor is formed by protruding from one side wall of the pedal pieces to the braking hubs; the linkage pipe is sleeved on the wheel shaft; and the pedal pieces are connected to the two ends of the linkage pipe. Compared with the prior art, the braking mechanism for the baby carriage provided by the invention has the advantages that the linkage pipe is sleeved on the wheel shaft and is connected with the pedal pieces, and when any one of the pedal pieces is operated for braking, the other pedal piece is driven to act by the linkage pipe, therbey achieving an effect of one-treading and double-braking. Besides, the braking assistor of the pedal pieces gets in/out of the blocking slots of the braking hubs, therbey realizing a braking/actuating process of the braking mechanism for the baby carriage. The braking mechanism for the baby carriage has the advantages of simple structure, simple matching relation between the braking assistor and the blocking slots, and low cost. Meanwhile, the invention discloses the baby carriage.

The invention belongs to the technical field of power system relay protection, and particularly relates to a logical judgment-based substation area protection system and method. The system is characterized by comprising a data reading module, a logic judgment module and a protection action module which are sequentially connected. The method comprises the steps of collecting data; obtaining fault information through logic judgment by using a collected secondary protection device action logic signal of a substation; and sending out a tripping signal to a corresponding circuit breaker according to the fault information. According to the logical judgment-based substation area protection system and method, the backup protection performance of in-station components is effectively improved; the problems that traditional staged backup protection is difficult to match and the action delay is long are solved; and the logical judgment-based substation area protection system and method are simple, reliable and easy to implement.

This invention relates to a lifting support unit of a plastering device of a plastering machine which is composed of a square frame and four rolling wheels at the four corners of the frame, the four rolling wheels are in the same plane parallel to the frame. Since the supporting unit is composed of a square frame and rolling wheels, they only coordinate with two longitudinal sideways at both sides, the matched relation is simplified and easy to be regulated, besides, its easy to mount/dismantle the two horizontal formed by two plug-in sections.

The invention discloses a laser spectrophotometer. The laser spectrophotometer comprises a light splitting disc, an absorption tank and a detector, wherein the light splitting disc comprises a plurality of single-color laser devices; the plurality of single-color laser devices are arranged on the light splitting disc at intervals along the circumference, so that the switching of the single-color laser devices is realized through rotating the light splitting disc; the absorption tank is used for storing a test sample to be measured; the absorption tank is arranged at the rear end of the light splitting disc; the detector is arranged at the rear end of the absorption tank so that one single-color laser device in the light splitting disc emits laser and the laser passes through the absorption tank to reach the detector; and the detector is used for detecting relative parameters of the laser passing through the absorption tank. The invention provides the laser spectrophotometer which is used for measuring through the rotary single-color laser devices; and by taking a plurality of monochromatic light with relatively good coherence as a measurement light source, the disadvantage that the measurement precision of a spectrophotometer in the prior art is not high is improved, and the laser spectrophotometer has relatively wide applicability and practical value.

The invention relates to a split internal combustion engine and particularly belongs to the technical field of internal combustion engines. The split internal combustion engine comprises a first cylinder, a second cylinder, a temperature control device and a valve device, wherein the temperature control device is connected with the first cylinder and the second cylinder. A first piston is arranged in the first cylinder and a second piston is arranged in the second cylinder.
