The present application relates to an elastic jack terminal, a connection socket and an electrical connector. The elastic jack terminal further includes a mounting shaft section, a contact structure and a positioning structure. The contact structure is connected to the end of the mounting shaft section. The contact structure includes a plurality of contact arms. The plurality of contact arms are arranged at intervals in the circumferential direction of the mounting shaft section to enclose and form a plug hole for a pin terminal to be inserted. The contact arms are elastic bodies, enabling the plug hole to elastically expand and contract. The positioning structure includes a connecting arm and an abutting ring. The abutting ring has a through hole. Along the central axis of the mounting shaft section, the abutting ring is located at one end of the contact structure away from the mounting shaft section and is arranged at an interval from the contact structure. The abutting ring is used for abutting and positioning with an insulator. The through hole is aligned with the plug hole. One end of the connecting arm is connected to the mounting shaft section, and the other end is connected to the abutting ring. Both the contact structure and the positioning structure are generally annular structures, so they can be directly formed by rolling and stamping a sheet material, and the processing method is simple.

The present application relates to a kind of follow-up drop-off electric connectors, follow-up shell lower end opening is connected with plug, follow-up shell is equipped with the push plate of guiding and lifting, push plate is connected with top rod sleeve, top rod sleeve is coaxially sleeved with top rod, top rod upper part side wall is provided with steel ball through-hole, top rod middle part is provided with top rod step, top rod sleeve lower inner wall is provided with lock sleeve groove;Lock sleeve is sleeved below top rod sleeve, lock sleeve lower inner wall is provided with lock sleeve groove, steel ball is inserted into lock sleeve groove to realize rigid locking;Push plate lower end is connected with four-link hinge connecting seat plate with rectangular four corners, connecting seat plate is connected with plug;Follow-up shell is equipped with cam that can be pressed to push plate.The present application has high insertion accuracy, can effectively meet the plug drop-off under the follow-up state of plug-in socket, and guarantee effective separation.

This utility model provides a traction device, including: a frame, a traction seat, and a locking rod. The frame is movably arranged along a preset trajectory. The traction seat is installed on the top of the frame and is located on the side of the frame closer to the drying oven. The traction seat has an insertion slot that extends along the length of the frame. The insertion slot is for the insertion and engagement of traction fittings on the placement frame. The locking rod extends along the width of the frame and is movably inserted into the traction seat along the width of the frame. The side wall of the insertion end of the locking rod has a guide slope, and the locking rod has an initial state, a clearance state, and a locked state. When the traction seat is away from the placement frame, the insertion end of the locking rod is located in the insertion slot, and the locking rod is in the initial state. This traction device effectively solves the technical problem in the prior art where, after the profile has been dried, the operator needs to enter the high-temperature drying space to manually push out the placement frame.

The utility model relates to the technical field of foundation pit supporting, in particular to a novel foundation pit supporting structure which comprises a supporting plate, a sleeve, a telescopic rod, a limiting assembly and a screw rod and is characterized in that the telescopic rod is inserted into the sleeve in a sliding mode, the limiting assembly is connected to the outer surface of the telescopic rod in a sleeved mode, and one side of the limiting assembly abuts against one end of the sleeve. The supporting structure has the advantages that when the supporting structure is installed between the two supporting plates, the length of the supporting structure of the supporting plates can be roughly adjusted by rapidly sliding the telescopic rod in the sleeve, after rough adjustment, the limiting assembly is clamped on the outer surface of the telescopic rod, the telescopic rod cannot be continuously inserted into the sleeve, and finally the supporting structure is installed between the two supporting plates by rotating the limiting nut. The supporting structure of the supporting plate can be accurately adjusted by adjusting the telescopic rod, the supporting structure can be rapidly assembled through the two steps of coarse adjustment and fine adjustment, and therefore time and labor are saved during adjustment of the supporting structure, and the assembling efficiency of the supporting structure is improved.
