The utility model relates to the technical field of tensioner, and disclose a kind of tensioner structure, it includes first frame, second frame, belt shaft spare and ratchet, the first frame and second frame are rotatably connected by belt shaft spare, first frame and second frame can rotate around belt shaft spare, second frame is located in the inside of first frame, the outer end both sides of belt shaft spare are all sleeved with ratchet, and the ratchet of both sides is located the outside both sides end of first frame respectively;The utility model, by the ratchet being arranged in the outside both sides end of first frame, so that only inside surface and first frame rub in the rotation process, and the design of convex ring is adopted, effectively reduce the friction area between ratchet and frame, reduce friction force, compared with traditional ratchet built-in, double-sided friction, the ratchet external mode of the device, single-sided friction stress, and the design of convex ring, reduce friction force, so that tensioner is more smooth in the process of loosening, improve use efficiency and operation experience.

The application discloses a device and method for synchronous or asynchronous regulation of mode conversion of an inner and outer channel of a nozzle, comprising a shell, an adjustable front-side air inlet valve, a crank driving unit, a rack and pinion transmission pair, a rear-side inner channel control mechanism, a flow channel support, a center body, a support and a control unit; the device adopts an integrated design of the adjustable front-side air inlet valve and the rack, and a driven conical wheel alternator of a blade disc driving ring, the rack and a slide rail can be assembled in a positive or reverse manner to realize synchronous / asynchronous switching of the inner and outer channels, the support is aerodynamically designed and the nozzle has an integrated cylindrical shape, a rear-side annular wall plate can be opened and is provided with a multi-position sealing structure, and a gas pressure detection device and a piezoelectric detection component cooperate with the control unit to form a closed-loop control link. The method realizes mode conversion based on the device. The application realizes precise switching of multiple modes, has high linkage precision, strong anti-interference capability, reliable sealing and convenient maintenance, is suitable for take-off, cruise and other working conditions, and can be widely applied to the fields of aerospace and industrial power equipment.

The invention relates to the technical field of tracked vehicles, in particular to a track shoe structure suitable for all terrains. Comprising a creeper tread, wingspans are fixedly connected to the left side and the right side of the creeper tread, a groove is designed in the bottom of the creeper tread, the depth and the width of the groove are determined according to vehicle driving requirements and strength requirements, and splayed ribs are fixedly connected into the groove; the grounding area is increased through the wingspan, the grounding specific pressure is effectively reduced, and a vehicle is not prone to sinking on the soft ground; the front ground gripping teeth and the rear ground gripping teeth at the bottom of the track shoe enhance the adhesive force with the ground, so that the slipping phenomenon in wet, slippery and soft terrains is effectively reduced; the splayed ribs designed in the grooves can automatically discharge accumulated soil in the running process of the vehicle, resistance is prevented from being increased, and the running efficiency under the muddy road condition is guaranteed; the adjacent track plates are connected in the mode that the built-in clamping rings are matched with the track pins, compared with a traditional external mode, the structure is not prone to falling off, and the connection stability of the track system under the bumpy road condition is greatly improved.
