The invention provides a rubber main spring assembly and an automobile left suspension assembly, and relates to the technical field of automobile parts, the rubber main spring assembly comprises an outer pipe, an inner pipe, a rubber main spring and a top spring steel plate, and the inner pipe is located in the outer pipe; the rubber main spring is arranged on the inner wall of the outer pipe and comprises a top limiting rubber block and a supporting rubber block, the top limiting rubber block is located above the inner pipe, and the supporting rubber block is fixedly connected with the inner pipe; the top spring steel plate is arranged in the top limiting rubber block, the lower surface of the top spring steel plate faces the inner pipe, and the two ends of the top spring steel plate are fixedly connected with the outer pipe. The top spring steel plate is arranged in the top limiting rubber block, so that the rigidity of the top limiting rubber block is improved, the load resistance of the top limiting rubber block is higher, and the top spring steel plate and the top limiting rubber block act together to buffer the impact force of the corbel; and the problem of brittle failure caused by excessive impact between the corbel and the top of the welding ring during strenuous movement is avoided.

The embodiment of the utility model provides a pressing block, a connecting piece, a pressing block assembly and a photovoltaic system. Wherein the photovoltaic system comprises C-shaped steel, a connecting piece and a photovoltaic frame; the C-shaped steel forms a strip-shaped opening, and the connecting piece is located in the strip-shaped opening and hooks the two side edges of the C-shaped steel. The photovoltaic frame is erected on the strip-shaped opening and comprises a convex edge; the pressing block comprises a pressing block body, the pressing block body comprises a first surface, the two opposite ends of the pressing block body respectively form hooked edges protruding out of the first surface, and the hooked edges are arranged on the convex edges in a pressing mode; the pressing block is connected with the connecting piece in a fastening mode so as to fasten the photovoltaic frame and the C-shaped steel. According to the embodiment of the invention, the pressing block is pressed on the convex edges of the two adjacent photovoltaic frames, the pressing block and the connecting piece are fastened through the fastening piece, the photovoltaic frames and the C-shaped steel are fastened, the hooked edges of the pressing block are pressed on the convex edges of the photovoltaic frames, and the acting force between the hooked edges and the convex edges acts on the same line instead of the same point. And the fixed photovoltaic frame has relatively high load resistance.

The utility model provides a kind of unmanned aerial vehicle aileron structure, comprising: composite skin, it is cylindrical structure, and at least one weight-reducing hole is set on it and passes through, both ends of weight-reducing hole and the both ends of cylindrical structure are through-penetrating;Two mounting plates are respectively installed in the opposite two sides position of composite skin, and the side surface of mounting plate close to composite skin is provided with the protruding part compatible with the weight-reducing hole of composite skin, the protruding part can be embedded in weight-reducing hole, so that the end of mounting plate and composite skin is fixed together.The utility model can realize once solidification forming by the cooperation of composite skin and mounting plate, and the forming manufacturing operation of aileron can be completed, through end insertion type connection, ensure the high coaxiality of left and right mounting plates, forming process is simple, forming efficiency is higher, and it is more stable and safe, solve the problem of the difference of coaxiality, assembly complex, weak overall rigidity of traditional multi-component assembly aileron.

The utility model discloses an overhead transmission line steel pipe pole structure with a top sealing plate with a line hanging function, which comprises a pole body, a plurality of cross arm structures are symmetrically arranged on the pole body, a ladder stand is arranged on the pole body, and an anti-climbing device is arranged at the bottom of the ladder stand. Compared with the prior art, the utility model has the advantages that the structure is simple, and the use is convenient; wire hanging is integrated, wire hanging holes are directly formed in the top sealing plate, the welding procedure is omitted, cost is reduced, and reliability is improved; the anti-load capacity is high, the variable cross-section rod body and the flange base are designed, and through experimental verification, 34.329 kN transverse wind load and 25.186 kN longitudinal wire tension can be borne; the cross arm and the pole body are in modular connection, and the crawling ladder is inserted and mounted, so that the field operation time is shortened; the safety is high, and the service life is prolonged due to dual protection of climbing thorn prevention and a hot-dip galvanizing process.

This utility model discloses a glass fiber reinforced continuously wound spiral rib pipe for tunnel lining. The pipe and the spiral rib layer continuously wound on the pipe are provided with an interface layer on the surface of the pipe and the spiral rib layer. The pipe includes an inner lining layer and a structural layer. A grid layer is laid on the surface of the structural layer. All layers are connected as one. The pipe of this utility model includes an inner lining layer and a structural layer. By adding continuously wound spiral ribs, a grid layer and an interface layer to the outer surface of the pipe, a spiral rib pipe can be used in tunnels. It has a reasonable manufacturing cost and strong load-bearing capacity.
