CN106450926A - Device for realizing easy plugging and no falling of plug - Google Patents

Abstract

The invention discloses a device for realizing easy plugging and no falling of a plug, and aims to provide a device in which self falling of the plug from a socket is prevented and labor saving is realized in pulling the plug out of the socket. The device is composed of the plug, the socket, a jump spring column, jump springs, a pushing fork, a press button, a connecting rod mechanism, etc. The central part of the plug pin is provided with the jump spring column. The lower ends of the jump springs which are symmetrically distributed are fixed on the jump spring column. The jump spring column is provided with rectangular slots for accommodating the upper ends of the jump springs in pressing-into. The socket is provided with a cylinder hole of which the upper opening is smaller than the diameter of the cylindrical hole. The jump spring is compressed in passing through. After resetting, the snap spring is blocked in the upper opening of the cylindrical hole, thereby locking the plug which is inserted into the socket. The jump spring column can be inserted into the cylindrical hole. The lower part of the cylinder hole is provided with the pushing fork which is hinged with the connecting rod mechanism. The other end of the connecting rod mechanism is connected with the press button. On the condition that the press button is pressed, the connecting rod mechanism is pushed. The pushing fork which is hinged with the connecting rod mechanism upwards press the jump spring, thereby pushing out the jump ring column and the plug which is integrated with the jump ring column.

Description

Plug easily pulls out and does not fall off device

Technical field

The present invention relates to a kind of plugs and sockets, especially relating to one kind prevents plug from voluntarily coming off from socket, and labour-saving when pulling the plug out of the socket Device.

Background technology

Laborious when existing plugs and sockets pulls the plug out of the socket, using often can make plug abjection socket because external force is added on plug cord, interrupt electricity consumption.

Content of the invention

Instant invention overcomes the above-mentioned deficiency of prior art, provide a kind of plug that the device of socket when being drawn out easily and using, will not be spontaneously decoupled.

The present invention adopts the following technical scheme that：A kind of plug easily pulls out and does not fall off device, by plug, jump ring post, socket, jump ring, push away fork, Button, connecting rod etc. form.In the middle of several pins of plug, there is jump ring post, described jump ring post has symmetrical jump ring, jump ring lower end is fixed On jump ring post, jump ring is in 7 fonts, and 7 word wedge angles outwardly, have strip space in jump ring post, jump ring upper end can be pressed in this strip space or Eject.

On socket, there is a cylindrical hole jump ring post insertion position relatively, and this cylindrical hole upper port is slightly less than cylinder bore diameter, jump ring post head and jump ring pressure This cylindrical hole upper port can just be passed through, this cylindrical hole bottom has a fluted column shape to push away fork, it is hinged with linkage that this pushes away fork lower end earhole after lower；Press Button on lower socket, promotes linkage to drive and pushes away fork and upwards jump ring is pressed into strip space promote jump ring post lower surface in jump ring post, will insert The crown goes out.

The invention has the beneficial effects as follows：After plug insertion socket will not self falling, ejection safe plug laborsaving.

Brief description

Accompanying drawing is the structural representation of the present invention.

Specific embodiment

The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：

Accompanying drawing is embodiments of the invention, and plug 1 lower end is jump ring post 8, and this jump ring post 8 has two symmetrical jump rings 2, card yellow 2 Lower end be fixed on jump ring post, upper end is in 7 fonts, and 7 word wedge angles outwardly, described jump ring post 8 have two strip spaces, and jump ring upper end can be pressed Enter in this two strips space, socket 4 corresponding jump ring post 8 insertion position, there is a cylindrical hole, the upper port of this cylindrical hole is slightly less than cylinder bore diameter, When jump ring post 8 inserts this socket cylindrical hole with plug 1, jump ring 2 is pressed into two strip spaces by socket cylindrical hole upper port, after upper port, Jump ring 2 ejects, and 7 font head gears are in socket cylindrical upper end mouth it is impossible to exit；Press the button 5, promote linkage 7, make to push away fork 3 to Upper pressure jump ring 2 enters in described strip space, promotes jump ring post 8 outwards to deviate from socket 4 simultaneously；Spring 6 makes button 5 reset.

Claims (2)

1. a kind of plug easily pulls out and does not fall off device, by plug, socket, jump ring post, jump ring, pushes away fork, button, connecting rod etc. and forms, it is characterized in that：? , there is a jump ring post at the middle part of plug base pin, and symmetrical jump ring lower end is fixed on described jump ring post, the relatively described jump ring post insertion of described socket Position have a cylindrical hole, described cylinder in the hole pushes away fork, described push away fork hinged with linkage, described linkage is connected with button.

2. plug according to claim 1 easily pulls out and does not fall off device, it is characterized in that：The length accommodating jump ring press-in is had on the face of cylinder of described jump ring post Bar shaped space, the upper port of described socket cylindrical hole is less than the diameter of described cylindrical hole, and after press-in jump ring post, jump ring is blocked in described socket after resetting In cylindrical hole upper port.
