The utility model discloses a high-strength fuel tank which comprises a fuel tank body and a fuel tank opening formed in the top of the fuel tank body, and a plurality of fixing assemblies and unbuckling assemblies are arranged in the fuel tank body. The fixing assembly forms a triple fixing structure through mechanical embedding of the supporting rod and the embedding groove, covering and locking of the limiting sleeve on the positioning block and the adsorption effect of the magnetic attraction ring, and stable clamping is achieved in cooperation with the limiting block pre-tightened by the torsional spring. The unlocking assembly adopts a linkage mechanism that a lifting rod drives a rotating rod to rotate, unlocking track control is achieved through sliding fit of a movable groove and a limiting column, and self-locking in the unlocking state is guaranteed through a friction plate. The fuel tank has the advantages of being convenient to install and reliable in locking, single-hand rapid disassembly and assembly are achieved through modular design, the multiple interlocking structures of the fuel tank effectively resist vibration impact, the fuel tank is particularly suitable for fuel systems of vehicles and other mobile equipment, and the maintenance efficiency is improved.

The utility model relates to the related technical field of mounting structures, in particular to a packing grid mounting structure of a packed tower, which comprises a packed tower body, the bottom of the packed tower body is fixedly connected with a base, the top of the packed tower body is provided with an exhaust port, the inside of the packed tower body is provided with a sprayer, and the sprayer is connected with the base. A filler body is arranged at the bottom of the sprayer, two first mounting blocks are fixedly connected to the interior of the filler tower body, a fixing groove is formed in the top of each first mounting block, a connecting block is attached to the interior of each fixing groove, and a grating frame is fixedly connected to the top of each connecting block; the lifting rings are matched with the hooks to achieve integral lifting of the grating frame, the telescopic blocks are matched with the connecting blocks to achieve quick release, and the grating frame can be quickly switched among different mounting blocks by combining the automatic reset function of the turnover blocks and the torsional springs. By means of the design, flexible adjustment of the height position of the filler body is achieved, and different process requirements are met.

This utility model belongs to the field of circuit breaker technology and discloses a circuit breaker. The circuit breaker includes a main housing, within which are phase electrode housings, a tripping drive element, and a traction rod. An arc-extinguishing chamber is located within the phase electrode housing, and an air hole communicating with the arc-extinguishing chamber is opened on the phase electrode housing. The tripping drive element includes a drive rod, with its first end corresponding to the tripping part of the traction rod, and its second end having a drive groove facing and communicating with the air hole. The middle part of the drive rod is hinged to the phase electrode housing. Gas generated within the arc-extinguishing chamber is discharged through the air hole into the drive groove to drive the drive rod to rotate. The first end of the drive rod pushes against the tripping part to drive the traction rod to trip. The circuit breaker provided by this utility model achieves rapid tripping via pneumatic means, with high breaking efficiency, rapid response, and high force transmission efficiency.

The application belongs to the technical field of fuses, in particular to an outdoor high-voltage current-limiting fuse, comprising an epoxy tube; the upper and lower ends of the epoxy tube are respectively sleeved with an upper locking ring and a lower locking ring, a static contact is arranged on the upper locking ring, the static contact is installed below an anti-icing cover through bolts, and a first spring is installed on the static contact; in the application, a striker is independently arranged in a support column, a trigger branch and a main fuse passage are separated in structure, assembly complexity and interference risk in operation caused by passing of a constantan wire through a hole in the support column in traditional design are avoided; meanwhile, a connecting cavity and a plug-in connector structure are arranged in a connecting piece at the lower end, and a connecting wire in a rotating seat is matched, stable electrical leading-out is realized, and through a rotatable connecting frame design, the fuse is allowed to flexibly adjust an installation angle according to the direction of incoming and outgoing lines on site, and construction and maintenance in a complex outdoor environment are greatly facilitated.
