A linkage cabinet door lock includes a lock body and an installation structure. The lock body has a locking assembly and a limiting mechanism. The locking assembly includes a bolt, a gear locking pin, and a rack. The bolt is slidably disposed in a bolt groove. A gear locking pin is rotatably disposed on the outside of the bolt groove, with a gear at one end and a locking end at the other. The gear meshes with the rack on the bolt to achieve linkage between the bolt and the gear locking pin. The locking assembly has unlocked and locked states. In the unlocked state, a compression spring pushes the bolt out of the lock body, and the locking end screws into the lock body. In the locked state, the bolt retracts into the lock body, and the locking end screws out of the lock body. During the sliding of the bolt, the rack drives the gear locking pin to rotate, realizing the switching between the two states. The limiting mechanism includes a limiting spring and a limiting actuator. The limiting head of the limiting spring is used to prevent the bolt from popping out. The limiting actuator controls the deformation of the limiting spring to release the limiting of the bolt. This invention has a simple structure, is easy to operate, and can realize individual control of the cabinet door on which this mechanism is installed.

The invention discloses a solar modular photovoltaic module convenient to clean, and relates to the technical field of photovoltaic power generation, the solar modular photovoltaic module comprises a frame mechanism, the frame mechanism comprises a main beam, a side beam, a middle beam, an auxiliary beam, a side rod, a stop column and a storage chute; a water collecting mechanism is installed on the top face of the main beam and comprises a supporting column, a water collecting tank, a water distribution chamber and a water injection rod.

The utility model discloses an unlocking pendulum device for a seismometer, which relates to the technical field of seismometers and comprises a support and a pendulum bob, one end of the pendulum bob is a connecting end connected to the support through a reed, the other end of the pendulum bob is a swinging end capable of swinging freely, and the unlocking pendulum device is characterized by further comprising a positioning block matched with the swinging end of the pendulum bob. The positioning block can stretch out or retract relative to the support through the driving assembly, the positioning block can be matched with the swing end of the pendulum bob when stretching out, the pendulum bob can be limited to the positioning block in the stretching-out state, and when the positioning block retracts, the swinging path of the pendulum bob can be avoided. According to the seismometer pendulum unlocking and locking device provided by the utility model, the swing end of the pendulum bob is limited through the extension of the positioning block, so that the pendulum bob is locked in a non-use state, the protection on the reed is realized, and the limitation on the pendulum bob is relieved through the retraction of the positioning block, so that the pendulum bob can swing freely in a use state.

The utility model discloses a hydraulic quick locking device and belongs to the technical field of hydraulic locking mechanisms. The hydraulic cylinder comprises a hydraulic cylinder body, a hydraulic piston, a hydraulic rod and an oil tank, the hydraulic piston is located in the hydraulic cylinder body, and the hydraulic rod is fixed to the hydraulic piston and penetrates out of the upper end of the hydraulic cylinder body. An upper oil passing opening and a lower oil passing opening are formed in the positions, above and below the hydraulic piston, of the side portion of the hydraulic cylinder respectively, the outer portion of the hydraulic cylinder and the upper oil passing opening are communicated with an upper oil pipeline, the outer portion of the hydraulic cylinder and the lower oil passing opening are communicated with a lower oil pipeline, and the upper oil pipeline and the lower oil pipeline are communicated with the oil tank at the same time. And an upper electromagnetic valve and a lower electromagnetic valve are respectively arranged on the upper oil pipeline and the lower oil pipeline. According to the utility model, position locking and positioning adjustment can be rapidly carried out on a bearing part to which external force is applied, the safety is higher, and the service life is longer.

The utility model belongs to the technical field of magnetic cup covers, and particularly relates to a magnetic cup cover which comprises a cup cover shell, the cup cover shell is composed of a main body and a cover body which are mutually fixed, the magnetic cup cover comprises a rocker, the upper end of the rocker penetrates out of the cup cover shell and is pushed by a user, the lower end of the rocker is located in the cup cover shell, and a magnet or an iron block is arranged at the lower end of the rocker. A rocker arc-shaped surface is arranged on the rocker, an abutting arc-shaped surface is arranged on the main body or the cover body, and the rocker arc-shaped surface is attached to the abutting arc-shaped surface; an elastic piece is arranged on the rocker and pulls the rocker to keep a vertical state; the penetrating-out end of the rocker is pushed, the rocker swings by leaning against the arc-shaped face, and therefore the magnet or the iron block at the lower end of the rocker is moved.
