The invention relates to the technical field of air storage air compressors, and discloses a high-stability air compressor for energy storage, which comprises a damping base and a damping assembly, a compressor is arranged on the inner wall of the damping base, and an air inlet pipe is fixedly mounted on the right side of the compressor; the damping assembly comprises a moving frame, an adjusting hole, a moving hole, an elastic telescopic rod, a limiting groove, an elastic telescopic plate, an elastic telescopic roller and a damping frame, the moving frame is fixedly installed at the bottom of the compressor, the adjusting hole is formed in the front side of the damping base, and the moving hole is formed in the front side of the moving frame. When the elastic telescopic plate is pressed to move downwards, the elastic telescopic plate is separated from the limiting groove and the limiting to the elastic telescopic rod is relieved, the triggering mode of pressing unlocking can prevent limiting failure caused by accidental touch in the daily operation process, and the design of automatic limiting after resetting can ensure that the elastic telescopic rod is stably locked; therefore, excessive vibration leakage caused by limiting falling during operation of the compressor is avoided.

The utility model discloses a photovoltaic power generation grid-connected protection device, and relates to the technical field of photovoltaic power generation. The high-low-voltage photovoltaic grid-connected cabinet comprises a high-low-voltage photovoltaic grid-connected cabinet body, a main circuit breaker and a plurality of branch switches are fixedly arranged in the high-low-voltage photovoltaic grid-connected cabinet body, the main circuit breaker is electrically connected with the branch switches, and the branch switches are all connected with external wires. And the main circuit breaker and the branch switch are used for controlling the on-off of the circuit. According to the photovoltaic power generation grid-connected protection device, through the synergistic effect of the moving assembly and the elastic mechanism, the wire rod forms a dynamic redundant structure, thermal expansion and cold contraction deformation can be automatically compensated, the redundant length is released during external pulling, and damage to a connection point can be avoided; the rubber pressing plate and the abutting plate form a graded fixing system, flexible pressing and rigid clamping are carried out on the bent part and the root part respectively, and it can be ensured that the wire connecting point is not prone to being affected when the redundant section moves.

The utility model discloses a quick connector of an LED (light-emitting diode) lamp string, which relates to the field of electrical connection devices and comprises a silica gel waterproof ring, a first connector, a cylindrical plug, a lock catch lug, a second connector, a cylindrical slot and a locking bump component. The other end of the first connecting piece is used for connecting a first wire, a metal slot is formed in one end, far away from the first connecting piece, of the cylindrical plug, and the lock catch lugs are symmetrically distributed in the circumferential direction of the cylindrical plug; one end of the second connecting piece is connected with the cylindrical slot in a sleeved mode, the other end of the second connecting piece is used for being connected with a second electric wire, a metal connector is connected into the cylindrical slot in an embedded mode, the multiple locking protruding block assemblies are symmetrically distributed in the circumferential direction of the cylindrical slot, and the silica gel waterproof ring is arranged on the outer surface of the cylindrical plug in a sleeving mode. According to the utility model, the rapid plugging operation among a plurality of LED lamp strings is realized, and meanwhile, the sealing and waterproof effects of the connector are improved.

This application relates to the field of electronic pen technology and discloses an electronic pen including a pen refill, a charging module, a pen cap, and a slider. A slide rail is provided on the outer wall of the pen refill, with its length parallel to the axial direction of the pen refill. The charging module is connected to the pen refill, passing through the outer wall of the pen refill, and has a charging port. A first end of the slider along the axial direction of the pen refill is connected to the pen cap, and a second end of the slider along the axial direction of the pen refill slides in conjunction with the slide rail, thereby causing the pen cap to switch between a first position and a second position along the axial direction of the pen refill. In the first position, the pen cap blocks the charging port; in the second position, the pen cap detaches from the charging port. This application solves the problem of exposed charging ports affecting product aesthetics and usability.
