The invention relates to a high-effect electrostatic protective component of a disk type voltage dependent resistor for a bridge-wire electric detonator. The high-effect electrostatic protective component comprises a disk type PCB and two voltage dependent resistor electrostatic protective electronic devices, wherein one voltage dependent resistor is connected with a pin-pin ignition loop in parallel via a circuit board, and the other voltage dependent resistor is connected with a pin-shell ignition loop in parallel via a circuit board; two sawtooth-shaped discharge electrodes are configured at the reverse side of the PCB, and form a pin-shell air gap electrostatic discharge channel together with the inner wall of a metal tube shell; the sawtooth-shaped discharge electrodes and the electrostatic protective devices are connected in parallel to form a double-insurance effect with pin-shell electrostatic protection. The pin-shell protection effect of the electrostatic protective component achieves the human body static electricity resistance above 50kV; the pin-pin protection effect achieves the human body static electricity resistance above 30kV, and can withstand multiple times of impact by electrostatic discharge without any capability change.

The invention discloses a valve mechanism for an engine and a vehicle comprising the valve mechanism. The valve mechanism comprises a valve mechanism body, a rocker component, a first roller, a second roller, a camshaft, supporting structures, a phase adjusting mechanism, and a third roller or limit pins. The bottom of the rocker component is provided with a drive molded surface which is suitable for directly driving a valve to move. The first roller and the second roller both can be arranged on the rocker component in a pivoting mode. The camshaft comprises an inner shaft and an outer shaft, the inner shaft and the outer shaft are coaxially arranged and provided with an inner shaft cam and an outer shaft cam respectively, and the inner shaft cam and the outer shaft cam can rotate along the corresponding shafts respectively. The outer shaft cam abuts against the first roller, the inner shaft cam abuts against the second roller, the supporting structures are arranged on the two sides of the rocker component and provided with circular arc cambers or sliding grooves, the third roller can be attached to the circular arc cambers in a rolling mode, and the limit pins can be matched in the sliding grooves in a sliding mode. The valve mechanism can achieve secondary opening of the valve, can lengthen the opening lasting time of the valve, and is simple in structure, and low in influence on the height of the engine.

A hydraulic machine with a hydraulic pressurizing mechanism comprises a main hydraulic cylinder, a pressurizing cylinder and a locking mechanism used for limiting the position of a cylinder body of the pressurizing cylinder, and the main hydraulic cylinder provides a power source; the pressurizing cylinder is driven by power of the main hydraulic cylinder, after the main hydraulic cylinder drives the pressurizing cylinder to move by a certain stroke, the locking mechanism restrains and fixes the position of a cylinder body of the pressurizing cylinder, the power end of the main hydraulic cylinder provides power for the pressurizing cylinder, pressure is transmitted through a pressure transmitting medium in the pressurizing cylinder, power output of the pressurizing cylinder is achieved, and the hydraulic machine generates pressurizing action. By optimizing the structural composition of the pressurizing mechanism, the hydraulic machine can generate large working pressure and has a large rapid mold opening and closing stroke so as to meet the requirement for extrusion forming of large metal parts.

A rail transit vehicle including car body and traction transformer, the traction transformer is fixed on the top of the vehicle body and the outer contour of the traction transformer is located in theroof contour line protruding in a direction away from the bottom surface of the vehicle body, Setting the traction transformer at the top of the car body and ensuring that the outer contour of the traction transformer is located in the contour line of the car roof is not only beneficial to avoiding the damage of pollution, blockage and scratch of the traction transformer to a certain extent, butalso prolongs the service life by reducing the failure rate and improves the working reliability of the rail transit vehicles. But also helps to reduce the height of the bottom surface of the car bodyfrom the ground, avoid adding a higher platform, and weaken the influence of the platform height, so as to improve its adaptability. Therefore, the rail transit vehicle provided by the invention is conducive to improving its working reliability and adaptability.

The invention discloses a glue dipping head for conductive glue coating. The glue dipping head comprises a connecting shaft, a rotating body, a glue dipping head base, glue dipping salient points and glue dipping shrinkage salient points, wherein the rotating body is fixedly arranged on the connecting shaft; the glue dipping head base is arranged at the bottom of the connecting shaft; the glue dipping salient points and the glue dipping shrinkage salient points are arranged on the glue dipping head base in matrix arrangement; and the glue dipping shrinkage salient points are positioned on the outermost side of the glue dipping head base. The glue dipping head has the advantages that the space layout of the glue dipping salient points is optimized, and the size and structure of the glue dipping salient points of a bonding pad of a chip are optimally designed, so that the ideal condition that effective overflow of the conductive glue on non-bonding pad parts of the chip and proper overflow of the conductive glue on the bonding pad parts of the chip is achieved; and according to the glue dipping head, the production efficiency and the quality of the conductive glue coating are improved, the viscosity change of the conductive glue and the height of the conductive glue in a glue dipping disc are less affected, and the glue dipping head is beneficial to large-scale production.
