This utility model discloses an insulating junction box for testing new energy batteries, relating to the field of junction box technology. It includes a detachably connected box body and a cover. A lead-in hole is provided on the side of the box body. A buffer assembly is installed inside the box body near the lead-in hole. The buffer assembly includes a limiting plate and a buffer spring. The buffer spring is vertically fixed between the limiting plate and the inner bottom of the box body. The limiting plate is located inside the cover when the buffer spring is not subjected to external force. Through the cooperation of the limiting plate and the buffer spring, this utility model allows a certain length of cable to be reserved inside the box during installation. When accidentally subjected to pulling force, the limiting plate and buffer spring can provide a certain buffering effect on the cable, preventing damage. Furthermore, after the pulling force disappears, the excess cable can be retracted into the box body under the action of the limiting plate and buffer spring, thus keeping the cable neat and tidy.

This application discloses a projection screen and projection device, belonging to the field of projection technology. The projection screen includes: a projection screen, a support assembly, and a roll assembly; one end of the projection screen is connected to the roll assembly; multiple support strips in the support assembly are arranged on the back of the projection screen in a direction away from the roll assembly. When the projection screen is rolled into multiple layers on the roll assembly, the nth layer of the multi-layer projection screen has at least a first support strip, and the (n+1)th layer of the projection screen has at least a second support strip. The orthographic projection of the first support strip on the nth layer of the projection screen and the orthographic projection of the second support strip on the nth layer of the projection screen have an overlapping area. Thus, the support strips on different layers of the projection screen can support each other, avoiding indentations or wrinkles on the projection screen when the support strips on different layers are completely misaligned. This solves the problem of poor display effect of projection screens in related technologies and improves the display effect of projection screens.

The utility model belongs to transformer technical field especially relates to a side outgoing line copper bar mounting support suitable for dry -type transformer, including frame and row clamp. The frame at least includes multiple mutually parallel cross bars and the vertical pole of fixed setting at the both ends of cross bar, is equipped with a plurality of first connecting holes for connecting on the cross bar, the row clamp is fixedly arranged on the cross bar through the first connecting hole, and the row clamp is used for fixing horizontal row. The utility model first connecting hole can be connected with insulating part and make insulating part fixedly set up on the cross bar, the outgoing row one end that leads out from coil leads out and is connected with coil, the other end is connected with insulating part, and the horizontal row fixed by row clamp is electrically connected with outgoing row, and horizontal row and outgoing row can be perpendicular to each other, and the special side outgoing line copper bar mounting fixed support is designed, and the design makes copper bar horizontal flat vertical, and the structure is compact and stable.

The utility model discloses a kind of pedestrian bridge truss type flange girder structure, including the girder in middle part and the flange in the both sides of girder, flange bottom is successively provided with truss integrated with flange, girder and flange lower stiffening rib along bridge length direction, truss formed by diagonal bracing and cross bracing forms continuous space triangle stable structure in plane and elevation, endows structure multilayer space change. Break traditional part flange stiffening rib adjustment to flange upper surface and cover with concrete pavement layer, avoid stiffening rib and truss interlaced, reduce construction difficulty, also have good landscape effect under meeting structural stress characteristics.

The invention discloses a pressing tool for a workpiece assembly and a mounting system for the workpiece assembly.The pressing tool comprises a base assembly, a pressing assembly, an ejector pin assembly and an ejector pin releasing part, the pressing assembly is movably arranged in an annular mounting space of the base assembly, part of the pressing assembly extends upwards into a first workpiece, and the ejector pin releasing part is arranged in the annular mounting space of the base assembly; in the loosening state, the pressing assembly is far away from the first workpiece, and in the pressing state, the pressing assembly presses the first workpiece outwards in the radial direction; the ejector pin assembly is provided with a plurality of ejector pins, and the ejector pins can move in the radial direction of the annular installation space and are used for abutting against a second workpiece installed in the first workpiece. The ejector pin releasing part is arranged on the base assembly and the ejector pin assembly in a pivoted mode and used for releasing the ejector pins in the tightened state one by one so as to abut against the second workpiece. According to the pressing tool for the workpiece assembly, the surface of the second workpiece can be prevented from being scratched when the first workpiece and the second workpiece are assembled, and the installation efficiency of the workpiece assembly can be improved.
