This utility model discloses a telescopic air duct high-efficiency heat dissipation structure, relating to the field of heat dissipation structures. It includes a blower and a connecting block located on the left side of the blower. A telescopic corrugated pipe is installed on the left side of the connecting block, and an air duct outlet is located on the left side of the telescopic corrugated pipe. A positioning chamber is installed at the upper end of the blower, and an auxiliary quick-release mechanism is provided inside the positioning chamber. In use, this telescopic air duct high-efficiency heat dissipation structure allows for angle adjustment by pulling the telescopic corrugated pipe, which itself has an angle-adjustable function. After adjusting the telescopic corrugated pipe so that the air duct outlet is aligned with the equipment requiring heat dissipation, the blower is started. The blower delivers air through the connecting block and into the interior of the telescopic corrugated pipe, then exits through the air duct outlet for efficient heat dissipation of the equipment. This design is convenient, simple, and easy to operate.

The utility model discloses a detachable keyboard's notebook computer relates to notebook computer technical field, include: the computer that is internally equipped with keyboard cavity, keyboard mechanism, be located in the keyboard cavity. This detachable keyboard's notebook computer, through the use of keyboard mechanism, can synchronous dismount keycap, and, the magnetic force ring board of embedding keyboard frame in with every keycap bottom's metal ring form magnetic attraction connection, make at the time of lifting keyboard frame, all keycap can be synchronized, neatly and together take out, greatly simplify the dismounting process, avoided the risk of losing the scattered parts, realized the integration management and maintenance of keyboard module, this detachable keyboard's notebook computer, through the use of positioning mechanism, can by an angle adjusting motor drive, through the linkage system that the synchronous sprocket, chain and cable constitute, can accurate control the synchronous rotation of multiple positioning rods at the four corners of keyboard cavity, thereby simultaneously release or lock the keyboard frame.

This utility model discloses a hanging device for LED screen modules, including: an LED screen module and a hanging device; a plurality of hooks are provided on the top of the hanging device; a positioning post is provided on the top of the LED screen module, and a positioning hole is provided in the middle of the positioning post; a connection hole corresponding to the positioning post is provided on the bottom of the hanging device; and a locking mechanism for detachably connecting with the LED screen module is also provided on the hanging device. Compared with traditional LED screen module hanging devices that connect the hanging device and the LED screen module through a plurality of nuts, this LED screen module hanging device allows for convenient and quick installation and disassembly of the hanging device and the LED screen module, reducing the difficulty of operation, reducing labor intensity, and improving work efficiency; and the locking mechanism connects with the positioning hole in the locked state, so that the positioning hole and the locking mechanism can achieve precise positioning in the locked state, ensuring the connection accuracy between the LED screen module and the hanging device, and improving the stability and reliability of the connection.

This invention relates to the field of circuit breaker mounting box technology, and discloses a modularly adaptable instantaneous circuit breaker integrated mounting box, including an integrated base. The integrated base serves as an overall mounting carrier for assembling protective covers, an instantaneous circuit breaker, and a signal acquisition harness. The instantaneous circuit breaker is detachably and fixedly installed inside the integrated base. Embedded nuts are provided on the support seats on both sides of the integrated base, and the two ends of the conductive busbar inside the instantaneous circuit breaker are respectively connected to the embedded nuts on both sides. Two protective covers are symmetrically installed on the support seats, adopting a flip-open structure and equipped with a vibration-proof and anti-detachment limiting structure to protect the conductive busbar. The signal acquisition harness is connected to the embedded nuts of the integrated base through a pressure plate. The integrated base has an arc guide groove and a harness buckle to limit the harness. A harness avoidance groove is provided below the harness placement position to reserve the bending radius. The harness interface is snapped and fixed in the interface slot on the outside of the integrated base.
