The utility model discloses an automobile tire fastening belt which comprises a macromolecule outer colloid belt and a steel wire rope inner net curtain, and the macromolecule outer colloid belt is wrapped outside the steel wire rope inner net curtain through mould pressing or injection molding. Due to the adoption of the steel-plastic composite structure, compared with an original woven polyester belt, the steel-plastic composite belt has the advantages of being high in strength, low in ductility, high in friction force with a tire joint surface and capable of preventing looseness under the condition of the same function. And moreover, the wear-resistant, scratch-resistant and anti-shearing characteristics are realized, and the service life can be greatly prolonged.

The utility model relates to an optical lens installation base which comprises an installation support which is of a rectangular structure, an annular groove is formed in the middle of the installation support, a lens fixing frame is arranged at the lower end of the installation support, adjusting pieces are evenly installed on the installation support, the number of the adjusting pieces is three, and the lens fixing frame is installed at the lower ends of the adjusting pieces. A sealing piece is installed at the interval between the installation support and the lens fixing frame, an optical lens is fixedly installed in the middle of the lens fixing frame, and a pressing piece is installed in the middle of the annular groove and used for pressing and fixing the upper end of the optical lens. According to the utility model, through differentiated advancing and retreating of the three groups of adjusting pieces, pitching, yawing and axial translation of the optical lens can be independently controlled, optical axis offset, coma and astigmatism are corrected, the adjusting precision is high, and the high-precision scene requirements of laser processing, microscopic imaging and the like are met.

This utility model provides a wheel for a ride-on woodland lawnmower, comprising a hub and a solid tire. The hub is made of fiberglass-reinforced nylon and includes a rim and spokes. The spokes are arranged radially and spaced apart within the rim, uniformly dividing the interior of the rim into multiple hollow areas. The solid tire is fitted over the rim and includes a tire tread and a shock-absorbing tire. The shock-absorbing tire is wrapped inside the tire tread and is made of polyurethane. The shock-absorbing tire is made of foamed rubber. This utility model aims to provide a wheel for a ride-on woodland lawnmower, suitable for ride-on lawnmowers, reducing the risk of punctures, lowering maintenance costs, and preventing lateral deformation during hillside operations.

The application discloses a kind of equipment for assembling for automobile hydrogen energy fuel cell production, it is related to hydrogen energy fuel cell production technical field, including workbench, the gantry is fixed on the workbench, the pressing mechanism for hydrogen energy fuel cell is installed on the gantry and is pressed, second cylinder is also fixed on the workbench left and right symmetry.This equipment for assembling for automobile hydrogen energy fuel cell production, by the mechanical linkage of the stacking mechanism and alignment mechanism, so that each stack one battery assembly, system is automatically executed once deviation correction action, so as to ensure that each component is righted after stacking, the component of the latter stack is taken as reference with the component that has been aligned, so that the flow channel alignment precision of final electric pile is extremely high, effectively guarantee that gas distribution uniformity and sealing reliability, and the process is fully automated, without manual intervention or complex visual detection, better satisfy actual production demand.

The utility model discloses a steel corrugated tunnel anti-sliding and supporting device, and belongs to the technical field of steel corrugated tunnel anti-sliding. Comprising annular I-shaped steel, webs on the annular I-shaped steel are connected in a welded mode through cross beams, a formed whole forms physical blocking during soil backfilling, the annular I-shaped steel is arranged outside, anti-sliding force can be provided, and the annular I-shaped steel is embedded into backfilling soil above a steel corrugated pipe tunnel through the geometrical shape of the annular I-shaped steel to prevent relative sliding; the supporting plate is arranged in the corrugated pipe, and supporting performance can be improved; and through the modular design and the prefabricated assemblies, the construction period is greatly shortened. Prefabricated production of the annular I-shaped steel and the cross beam reduces the complexity of site construction, the installation process is simple, convenient and rapid, and the construction efficiency can be remarkably improved. The connecting mode of the inhaul cables and the anchor rods is simple and easy to implement, the sliding force of the steel corrugated tunnel under the large-gradient foundation condition can be effectively resisted, and the anti-sliding capacity of the tunnel is remarkably enhanced.
