The invention provides a C-type locking pull-plug device which firstly realizes the on-site manual pulling and plugging of a module and the locking of an LRM under the ARINC600 standard. The C-type locking pull-plug device comprises a threaded rod, an ejection, a retaining sleeve assembly and a hinge assembly, wherein the retaining sleeve assembly is positioned between the ejection and the hinge assembly; the ejection is in threaded connection with the threaded rod, the retaining sleeve assembly is idly sheathed on the threaded rod, and the relative position in the axial direction between theretaining sleeve assembly and the ejection is fixed; and the hinge assembly is arranged at one end of the threaded rod and is fixedly connected with a mounting frame, the locking hook is fixedly arranged on the module, and the locking hook is matched with the retaining sleeve assembly. The invention has the advantages of simple operation, practicability, space saving and no use of special tools. By only operating the C-type locking pull-plug device, the module can be inserted in and pulled out of a slot of the mounting frame. When the module is inserted, better stability and intensity can be ensured without manual adjustment.
Description
technical field [0001] The invention relates to a locking and plugging device, in particular to a C-shaped locking and plugging device. Background technique [0002] At present, devices for locking and plugging modules are relatively common, but most of them often have the following problems when they are matched with mounting plates or mounting frames: [0003] The volume and weight of the locking and plugging device itself are difficult to ignore compared to the module. The special tool for module locking and disassembly is independent of the module. When disassembling the module, the special tool for disassembling the module needs to be loaded on the module itself, which will increase the load bearing of the module carrier. Considering the mechanical strength and structural stability, the special tool The weight of itself and its auxiliary parts may cause safety accidents. [0004] The locking and plugging process of the module is complicated. In the absence of auxilia...
