Abstract

The utility model relates to a plug locking device. The plug comprises a hollow pipe body. One end of the pipe body is used as a contacting part which is inserted with a socket, and the other end is connected with a transmission line. The utility model is provided with a locking element which can be sheathed on the pipe body by a rotating mode. The pipe body which nears to the transmission line and is positioned on one side of the locking element is provided with an evagination drawing surface. The maximum outer diameter of the evagination drawing surface is greater than the inner diameter of the locking element so that a hollow thread sleeve is butted and supported by the evagination drawing surface. The locking element is the hollow thread sleeve, and the socket is provided with a threading connection element which is locked with the hollow thread sleeve. The improved plug locking device of the utility model is butted and supported by the evagination drawing surface when the locking element is sheathed and combined on the pipe body so that the utility model is positioned one position so as to disorderly move.

Description

The plug latch fixing apparatus

The utility model relates to a kind of plug latch fixing apparatus, especially refer on this plug, be arranged with a rotatable locking element, plug is when plugging mutually with socket, lock member promptly can be locked in the spiral shell Yu element on the socket, make that plug is unlikely to be extracted easily, and the utility model is to be provided with an evagination near the transmission line place tiltedly to pull out face on body, when making lock member on being sleeved on body, can tiltedly be pulled out face by evagination replaces, and being positioned at the certain position place, unlikely unrest is moved, when making plug, when pouring into a mould insulator on the power line that connects at body one end, can not be subjected to the influence of lock member.

General plug is when plugging with socket, owing between plug and socket, be not provided with locked instrument, make plug be easy to from socket, come off, especially DC attaching plug, when leading the power line of mixing plug accidentally, promptly can make whole plug break away from socket, and the whole machine body power supply is disappeared, and then influence the use of body; A sheathed lock member on plug is promptly arranged; in socket, then be provided with the element that screws togather that cooperatively interacts; when plug was plugged on the socket, this lock member promptly can lock the screwing togather in the element of socket, to fix plug; this kind design on the contrary can be because of when making plug; owing to must on the power line of plug, pour into a mould insulator, however this lock member only be linked on the plug, do not located; regular meeting disorderly moves, and the carrying out of influence cast.

The purpose of this utility model is to provide a kind of plug latch fixing apparatus, mainly refer to insert to close include a hollow tube, body one end is connected with transmission line, the other end then can be plugged in the socket, in addition, the rotatable lock member that is arranged with on body, when plug is plugged in socket, can be by this lock member locking set screwing togather in the element on socket, make that plug is unlikely to be extracted easily, feature of the present utility model end of close transmission line on body is provided with an evagination and tiltedly pulls out face, so, when desiring on the transmission line that body one end connects, to pour into a mould insulator, because this locked instrument on being sheathed on body the time, can tiltedly being pulled out face by evagination and replace, and makes locked instrument be positioned in certain position and the unlikely transmission line place that moves to, can be comparatively convenient when casting insulated body, located the shortcoming that disorderly moves because of lock member significantly to improve common technology.

The purpose of this utility model is achieved in that a kind of plug latch fixing apparatus, and this is drawn together head and includes a hollow tube, and body one end plugs with socket mutually as contact site, and the body other end then is connected with transmission line.Other is provided with a lock member, it is set on the body rotationally, this body is provided with evagination and tiltedly pulls out face extending near transmission line and the side that is positioned at lock member, and this evagination is tiltedly pulled out the internal diameter of face maximum outside diameter greater than lock member, makes the hollow swivel nut tiltedly be pulled out face by evagination and replaces.

This lock member is a hollow swivel nut, and socket then is provided with this hollow swivel nut locks mutually and screws togather element.

This screws togather element and is shaped on thread at socket outer rim car, and swivel nut locks on the thread of this socket outer rim.

This body is not provided with evagination and tiltedly pulls out a side of face and extend and to be provided with flange being positioned at lock member, and this flange outside diameter is greater than the internal diameter of lock member, and withstanding of face tiltedly pulled out by flange and evagination in the lock member both sides on body.

According to the said structure analysis as can be known, the plug latch fixing apparatus via after the utility model improvement when making lock member on being sleeved on body, can tiltedly be pulled out face by evagination and replace, and be positioned at the certain position place, and unlikely unrest is moved.

Below in conjunction with accompanying drawing and specific embodiments, the utility model is described further.
