Compact plug-in with locking and pulling assisting device

Abstract

The invention discloses a compact plug-in with the locking and pulling assisting device. The device comprises a vertically-arranged panel, a rotating shaft parallel to the bottom edge of the panel isinstalled at the lower end of the panel, a handle is connected to the rotating shaft, and the handle comprises a connecting rod vertically installed on the rotating shaft and a locking groove structure arranged at the upper end of the connecting rod. A groove penetrating through the upper end and the lower end is formed in the side edge of the panel, a locking device is arranged at the upper end of the panel, the lower end of the connecting rod can rotate around the rotating shaft, the connecting rod can move towards the panel and be embedded into the groove by pressing the upper end of the connecting rod, and meanwhile the locking groove structure can be clamped into the locking device to lock the handle. An inner side lock hook is arranged on one side of the lower end of the handle closeto the back of the panel; and an outer side lock hook is arranged on one side away from the back of the panel. According to the invention, the maximum utilization of the available area of the plug-inpanel can be realized, and meanwhile, after the plug-in is locked, the panel and the handle form a concise whole without an external convex structure, so that the safe operation is facilitated, and the mistaken touch is avoided.

Description

technical field [0001] The invention relates to an automatic control box plug-in, in particular to a compact plug-in with a locking and pulling-out device. Background technique [0002] The plug-in of the automation instrument control system has a wealth of functions, and each function needs to be displayed or operated on the panel through the display device. Compared with the functions that the plug-in needs to realize, the operating space is often relatively tight. [0003] Usually, the design of the puller and the panel on the plug-in of the automation instrument control system is generally carried out separately, or the existing standard puller is purchased, and it often happens that the puller takes up a lot of panel height, which affects the panel can be used for display or operation space However, if a simplified small pull-out structure (such as using a non-extractable screw locking pull-out device) is used, the performance is often poor, which affects the user exper...

[0003] Usually, the design of the puller and the panel on the plug-in of the automation instrument control system is generally carried out separately, or the existing standard puller is purchased, and it often happens that the puller takes up a lot of panel height, which affects the panel can be used for display or operation space However, if a simplified small pull-out structure (such as using a non-extractable screw locking pull-out device) is used, the performance is often poor, which affects the user experience

In addition, the current common extraction aids usually have structural parts, such as handles, which are protruding relative to the panel, which is prone to scratches or accidental touches during use
