Background
The screw thread anticreep is the technical problem who often meets in the industry, in prior art, utility model patent 201620614195.3 applied for by Changzhou red reed electronics limited discloses a screw thread anticreep type audio and video connecting wire, two envelope portion pieces up the cylinder connecting portion that is used for wrapping up the transmission line, be equipped with the external screw thread on the outer periphery of cylinder connecting portion, be equipped with the opening on the outer periphery of cylinder connecting portion, be equipped with annular arch on the outer periphery of transmission line, annular arch and transmission line coaxial axle center, set up the external screw thread on the bellied outer periphery of annular, the external screw thread on the outer periphery of cylinder connecting portion is the same screw thread with the external screw thread on the bellied outer periphery of annular, the bellied tip of annular is equipped with the jack catch, the jack catch card is established in the opening, the cover is equipped with the sleeve on the transmission. The fixed more firm between the transmission line of this scheme and the cylinder connecting portion has effectually prevented the rotation between transmission line and the SCART interface, makes the utility model discloses an audio and video connecting wire is more firm, has avoided droing of 21 needles.
The utility model 201821908447.9, applied by Donghua Tokyo mining branch company, a Limited liability company (group), discloses an elastic thread anti-loosening nut, which comprises a nut body, wherein the nut body is provided with internal threads, a loosening-preventing nut mounting part which is integrally manufactured with the nut body is also arranged on the nut body, a loosening-preventing nut can be arranged in the loosening-preventing nut mounting part, the outer part of the loosening-preventing nut is provided with a conical surface which is matched with the groove structure, the loosening-preventing nut is provided with a gap, the gap and the axial direction of the loosening-preventing nut form an included angle, the loosening-preventing nut is provided with a circular bead, the size of the loosening-preventing nut is small, the nut and the nut are assembled into a whole, after the nut is arranged on a screw, the nut can; the production material is less, and the material cost can be reduced.
However, with the development of aerospace technology, a large number of connectors are arranged in a large number of large-scale devices, and during the use process, due to overlong time and different use environments, a plurality of connectors needing threaded connection may be loosened or even fall off, so that the transmission of signals is disabled, and in a special case, the aerospace devices even fall down, so that huge loss is caused. Therefore, it is necessary to design a thread anti-separation structure for such a connector.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a screw thread anti-drop structure to overcome prior art's not enough.
The utility model discloses a realize like this:
a thread anti-drop structure comprises a plug and a socket, wherein the plug is provided with a locking screw sleeve, the locking screw sleeve is provided with a locking screw sleeve safety hole, the socket is provided with a socket shell, and the socket shell is provided with a socket safety hole; the locking threaded sleeve of the plug is fixedly connected with the socket shell through threads; the safety chain is further included, and the locking screw sleeve safety hole is connected with the socket safety hole through the safety chain.
Compared with the prior art, the die has the main advantages that:
the utility model discloses there is the safety vent on the locking swivel nut, also has the safety vent on the socket, and after plug and socket threaded connection fastens, the rethread safety chain will lock swivel nut and shell fastening connection once more, can reach the purpose that prevents the screw thread not hard up. The structure has the advantages of simple structure, low cost, good thread falling prevention and the like, and is particularly suitable for electrical connection which does not need to be frequently disassembled in the aviation field.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "sleeved/connected", "connected", and the like are to be understood in a broad sense, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the anti-drop structure for screw threads of the present invention comprises: the plug 7 is provided with a locking threaded sleeve 2, and the locking threaded sleeve 2 is provided with a locking threaded sleeve safety hole 1; the socket 8 is provided with a socket housing 5, and the socket housing 5 is provided with a socket safety hole 4. The screw sleeve safety hole 1 and the socket safety hole 4 are connected through a safety chain 3. Thus, the plug 7 and the socket 8 are assembled to connect the lock screw 2 and the socket housing 5 together by the safety chain 3, as shown in fig. 2.
