The utility model relates to the technical field of vamps, and discloses an impact-resistant wear-resistant vamp which comprises a vamp body, toe protection blocks are fixedly connected to the outer wall of the vamp body, air holes are formed in the vamp body, flexible supporting strips are fixedly connected to the outer wall of the vamp body, outer-layer wear-resistant mesh cloth is arranged in the vamp body, and the outer-layer wear-resistant mesh cloth is arranged in the vamp body. The bottom of the outer-layer wear-resistant mesh cloth is fixedly connected with an anti-impact buffer layer, and the bottom of the anti-impact buffer layer is fixedly connected with an inner-side comfortable layer. According to the utility model, the impact force is dispersed through the foaming polyurethane buffer layer and the crossed supporting strips, so that the pressure on the feet during exercise is reduced, and the fatigue feeling is reduced; the hard protection blocks further protect the toes and avoid external force damage, the effect of improving the impact resistance is achieved, the problem that when a shoe is worn, supporting force is weak, and the shoe is prone to being damaged when being collided is solved, and the impact resistance of the vamp is improved.

This utility model provides an acceleration sensor device for monitoring temporary construction access roads, belonging to the technical field of monitoring temporary construction access roads. The acceleration sensor device includes: a monitoring base, a vibration sensing component, a signal transmission component, a protective shell, and a fixed support frame. The monitoring base is a cuboid structure with a mounting groove on its top, in which the vibration sensing component is installed. The vibration sensing component includes a sensor body, an elastic reset plate, and a counterweight. The sensor body is cylindrical and fixedly positioned at the center of the mounting groove. The counterweight is rotatably connected to the inside of the sensor body via bearings. The counterweight has an eccentrically distributed fan-shaped structure. This invention solves the technical problems of existing vibration monitoring devices for temporary construction access roads, such as complex structure, difficult installation, poor environmental adaptability, and low monitoring accuracy.

This utility model discloses a prefabricated fiberglass meter well, relating to the technical field of fiberglass meter wells. It includes a base, a lower well body, an upper well body, and a cover. The base has an installation groove with a raised water guide pipe on the bottom surface of the groove. The water guide pipe has a water inlet on its side wall. The bottom of the lower well body sits within the installation groove, and its bottom surface has an insertion hole corresponding to the water guide pipe. The water guide pipe is inserted into the insertion hole, and the water inlet on the water guide pipe is located inside the lower well body. A positioning component is connected to the water guide pipe, which presses the bottom wall of the lower well body tightly into the installation groove. The upper well body is detachably connected to the lower well body, and its top has a well opening. The cover is fastened to the well opening. This utility model uses prefabricated components for on-site assembly, greatly shortening the construction period and reducing the impact of construction on the environment and traffic. The design of the water inlet not only solves the drainage problem, but the overall structure combines drainage and assembly structures, making assembly more convenient.

This utility model relates to a mechanical structure for locking a side door from inside a cabinet. It includes a base, a rocker arm, a pivot screw, fasteners, and a side door connecting plate. The base is fixed inside the cabinet side door via a bottom slot. The pivot screw is fixed to the rocker arm via a groove, forming a sliding lever structure. The side door connecting plate engages with the head of the rocker arm via a square hole. By screwing in the fastener and pushing the tail of the rocker arm, the longitudinal pressure is converted into a lateral pressing force on the side door connecting plate by the head of the rocker arm, achieving concealed locking. The innovative design of this utility model lies in the fact that all components are built into the cabinet, with no exposed locking structure, improving safety and aesthetics. The fasteners and rocker arm work together to achieve linear adjustment of the locking force, adapting to complex working conditions such as vibration and temperature differences. This device has a simple structure and low cost, solving the problems of exposed and easily damaged traditional cabinet door locks and inconvenient adjustment. It is particularly suitable for outdoor equipment with high protection requirements, such as DC charging piles.
