A container sealing device installed on the neck of a container, a component of the container sealing device and a packaging container are composed of a cover component and a release component, the cover component is provided with a cover surrounding structure and a cavity cylinder structure, and the cover component is provided with a first buckle, a first positioning stop blocking buckle, a sealing piece, a supporting and pressing structure and an L-shaped concave chamber structure. The releasing component is provided with a thread or a clamping and blocking structure, a second buckle, a second positioning and stopping blocking buckle and a cutting structure. The cover component and the release component rotate mutually, so that the cutting structure of the release component starts to slide from the concave chamber structure, the transverse cutting effect is generated on the thinning connecting structure of the cavity cylinder structure to a preset position, the notch of the sealing piece is pushed to the outside of the cavity cylinder structure, and materials in the container sealing device are released into a container. The invention further provides a packaging container of the container sealing device, a packaging composition, an assembling method of the container sealing device and application of the container sealing device.

The positioning and fixing device for gear machining comprises a gear containing base, two threaded rods, an inner screw cylinder and an inserting plate, a metal limiting ring is horizontally fixed to the upper end of the gear containing base, and the two threaded rods are screwed to the left end and the right end of the metal limiting ring according to the thread principle; first metal limiting pieces are longitudinally installed at the opposite inner ends of the two threaded rods, and the multiple inner screw cylinders are horizontally welded to the inner side of the metal limiting ring; outer screw rods are screwed in the multiple inner screw cylinders according to the thread principle, the design solves the problems that an original device only depends on two pressing plates to clamp and fix a gear, the effect is common, once punching impact is large, the gear is prone to displacement, and the multi-direction pushing clamping and pressing structure is reasonable in structure and good in practicability; and it can be guaranteed that the gear is fixed before punching, the fixing effect is good, and operation and use and clamping and use of other sheet-shaped parts are facilitated.

This utility model discloses an encapsulation component for improving the power generation of a module under low irradiance, comprising, from top to bottom, an antireflective front glass, an antireflective film, a stacked crystalline silicon cell, a transparent film, and a grid-coated high-reflectivity back glass. The antireflective front glass includes high-transparency glass and a double-layer coating layer disposed on the upper surface of the high-transparency glass. The antireflective high-refractive-index film includes a cross-linked elastomer film layer disposed near the antireflective front glass and a high-refractive-index film layer disposed near the stacked crystalline silicon cell. This utility model features a double-coating design for the upper high-transparency glass, which improves light transmittance and incident rate, thereby increasing the incident energy of light reaching the solar cells and increasing module power. The middle anti-reflective high-refractive-index film layer, through a double-layer refractive index difference design, reduces the loss of light due to refraction and reflection caused by the refractive index difference, thereby increasing the incident light reaching the solar cells and increasing module power generation efficiency. The bottom layer of high-reflective grid-coated glass is a white grid-coated glass, which improves the secondary utilization rate of incident light. Matching the uppermost low-thickness anti-reflective glass, it can effectively ensure the overall mechanical load design of the module.

The invention relates to the technical field of packaging containers of products, and provides a container sealing device capable of releasing materials in an internally transverse cutting mode, the container sealing device is formed by assembling an inner cover and a control cover together, the inner cover is provided with a first buckle, a first positioning stop blocking buckle, a sealing piece, a supporting and pressing structure and a convex chamber structure, and the inner wall of a surrounding structure of the inner cover is provided with a thread or a clamping and blocking structure; a sharp structure which is in a protruding shape and points to the inner wall of the side wall of the control moving cover is arranged in the control moving cover, and the control moving cover is provided with a second clamping buckle and a second positioning stopping blocking buckle; the container sealing device is mounted at the neck of a container, the sharp structure starts to slide from the convex chamber structure by controlling the mutual rotation between the moving cover and the inner cover, the thinning connecting structure is transversely cut from the interior of the cylindrical enclosure structure of the inner cover to a preset position, and the notch of the sealing piece is pushed to the exterior of the cylindrical enclosure structure, so that the container is sealed. And the materials in the container sealing device are released into the container. In addition, the invention further provides a component of the container sealing device and a packaging container.

The application relates to a structure layout of a converter cabinet, in particular to a converter cabinet for a hybrid shunting locomotive, which comprises a frame cabinet body, the front side wall and the rear side wall of the frame cabinet body are regionally separated according to functions; a wind-cooling heat dissipation air duct is arranged in the frame cabinet body, the wind-cooling heat dissipation air duct is provided with mounting positions of different devices, a first maintenance door is arranged on the left side wall of the wind-cooling heat dissipation air duct, a second maintenance door is arranged on the right side wall of the frame cabinet body; detachable door plates are connected to the outer surfaces of each region of the front side wall and the rear side wall of the frame cabinet body, the detachable door plate arranged at the cooling device region is an air inlet mesh plate, the surfaces of the left side wall and the right side wall of the frame cabinet body which are not covered by the maintenance doors are covered with skins.
