The utility model discloses a new energy automobile discharging plug socket, aims at providing a new energy automobile discharging plug socket that is beneficial to improve safe use performance, it includes charging gun plug, is equipped with the prong and cylindrical groove respectively on charging gun plug, and the one end fixed connection of prong and charging gun plug, and the other end fixed of charging gun plug has the cable wire electricity connection respectively with prong and cylindrical groove, the socket board is equipped with the insertion slot that is matched with charging gun plug in one side of socket board, and charging gun plug is inserted and is pulled apart and is connected with insertion slot, and the insertion hole that is matched with prong and the convex column that is inserted and is pulled apart and is connected with cylindrical groove are equipped with respectively in insertion slot, and the convex column is fixedly connected with insertion slot, and the other side of socket board corresponding is equipped with several groups of socket mouth, and the prong on charging gun plug is inserted into insertion hole and is connected with socket mouth electricity after. The utility model has the beneficial effect that: the convex column is arranged in the insertion slot, and it is also beneficial to prevent other ordinary plugs from being inserted, and the purpose of being beneficial to improve safe use performance is achieved.

This utility model discloses a locking mechanism and an optical cable splice box, belonging to the technical field of optical cable splice boxes. It solves the problem that bolts may fall out of the holes in the optical cable splice box before the bolts and nuts are pre-tightened. It includes two detachably connected temporary fasteners. Each temporary fastener includes a insert and a limiting ring fixedly connected to the outer ring of one end of the insert. The inner ring of the insert, away from the limiting ring, protrudes outward to form an outward convex ring. When the two temporary fasteners are detachably connected, the insert of one set of temporary fasteners is inserted into the insert of the other set. This utility model can pre-fix the optical cable splice box body in advance. Then, when the bolt is inserted into the connection hole on the box body, the bolt needs to pass through the temporary fastener and will be threadedly connected to the bolt's thread, thus ensuring that the bolt does not fall out even when it is inserted into the box body and the nut is not pre-tightened.

This invention provides a plug-in / plug-out mechanism for an LED display device and an LED display device. The plug-in / plug-out mechanism includes: a power socket; and a power plug, including a second base, a second conductive element movably disposed on the second base, a plurality of first driving elements, and a plurality of first reset elements. Each first driving element can be subjected to a first driving force opposite in direction to a first reset force. When the first driving force on each first driving element is less than the corresponding first reset force, the second conductive element is in a first disconnected position. When the first driving force on each first driving element is greater than the corresponding first reset force, the plurality of first driving elements can move to drive the second conductive element toward the first conductive element, so that the second conductive element moves from the first disconnected position to the first connected position. The technical solution of this application effectively solves the problem in related technologies where the plug is prone to misalignment and difficult to insert into the socket.

This application discloses a tire gripping and moving mechanism, relating to the field of tire conveying technology. It includes: a transverse rail frame; a lifting base frame slidably mounted on the transverse rail frame; a gripping frame slidably mounted on the lifting base frame; and a clamping assembly for gripping tires mounted on the gripping frame. The clamping assembly includes a clamping base plate hinged to the gripping frame. The clamping base plate is oscillating and driven by a fourth power unit mounted on the gripping frame. A plurality of expanding plates are distributed circumferentially on the clamping base plate. These expanding plates are radially moved and mounted on the clamping base plate by a fifth power unit mounted on the clamping base plate. This solves the problems of traditional tire conveying, improves conveying efficiency, reduces labor intensity and labor costs, and enhances personnel safety.
