Abstract

The utility model belongs to a plug-in type connecting device used for leading a helmet of a pilot and an oxygen mask to be connected. The utility model mainly solves the problems that when a plug of an existing plug-in type connecting device is drawn out, labor is required, and the plug can not be easily drawn out. The utility model is characterized in that the plug comprises a box type structure which is matched with a socket and is composed of a plug body and a plug cover; both sides of the front end of the box type structure are respectively provided with a spacing tooth which can be reset; both sides of the back end are respectively provided with a scissor type handle which can lead the spacing tooth to be contracted; both sides of the socket are respectively provided with a clamping tooth. The scissor type handle is lightly nipped, the spacing tooth can be driven to be contracted in the plug body, and the plug can be conveniently drawn out of the socket.

Description

Pinch formula pin socket device

The utility model relates to a kind of plug-in jockey, the plug-in jockey that is connected between the particularly a kind of pilot's of being used for helmet and the oxygen mask.

The bindiny mechanism of the helmet and face shield, original adoption hook form, hook is fixed on the helmet, and link is fixed on the face shield, link entangles hook tension accommodation zone and get final product when wearing, but the weak point of this structure be exist be linked with tight, free problem such as inconvenience.In order to address these problems, people just use a kind of formula pin socket structure of pulling out instead, socket is fixed on the helmet, latch is fixed on the face shield, when wearing latch inserted that different teeth position gets final product in the socket, will pull at handle during the plug pin takes in the latch main body limiting tooth earlier, just can extract latch then, make the plug housing on the latch disengaging helmet, though this structure improves to some extent than hook structure, but when the plug pin, can produce an additional force and act on the limiting tooth, limiting tooth and socket latch are adjacent to, be difficult to take in the main body, latch is not drawn out easily, thereby still has the weak point of freeing inconvenience.

The purpose of this utility model is exactly to provide a kind of the elimination to pull out the additional force that the formula latch produces, the formula of the pinching pin socket device that makes latch be easy to plug and unplug at above-mentioned weak point.

Technical solution of the present utility model is: a kind of formula pin socket device of pinching comprises that both sides are provided with the socket and the latch of latch, is characterized in that: latch comprises a box structure that cooperate with this socket, that be made of latch main body and plug pin cap.These box structure front end both sides are provided with reducible limiting tooth; The both sides, rear end are provided with the scissor handle that this limiting tooth is shunk.

Two heads of the scissor handle described in the utility model technical solution can be two heads that entangle limiting tooth respectively, and rotating shaft is provided with the torsion spring that scissor handle is resetted.Limiting tooth is fixed in separately the rotating shaft, and its afterbody is provided with the back-moving spring that makes its clamping.

The utility model is owing to be provided with scissor handle on latch, and two head part of scissor handle are not entangled two heads of limiting tooth, thereby, when need are extracted latch from socket, as long as gently by pinching scissor handle up and down, just can drive limiting tooth easily it is taken in the latch main body, and can not produce the additional force of limiting tooth and socket latch, can in socket, extract latch easily.The utility model is owing to only adopt scissor handle arrangement to replace original slide block to pull out the formula structure on latch, and socket is constant, thereby it is simple especially to have structure, and characteristics very easy to use have reached the purpose of this utility model.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of the utility model latch;

Fig. 2 is the structural representation of the utility model socket.

The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2.Latch main body 1 and plug pin cap 6 constitutes box structures, and the handle of trough of belt is extended to both sides in the rear end of latch main body 1, is convenient to fixedly connected with face shield.Two scissor handles 2 are sleeved in the rotating shaft, and its two head part is not entangled two heads of limiting tooth 4.Torsion spring is located in the rotating shaft, and scissor handle 2 is opened.Two limiting tooths 4 are set in separately the rotating shaft, and its afterbody accompanies back-moving spring 5, can make it stretch out box structure.Back-moving spring 5 is fixed on the front end of box structure.Both sides are provided with latch in the socket 7, and are identical with existing socket.

Latch inserts in the socket 7, and the back-moving spring 5 that is clipped in limiting tooth 4 afterbodys makes limiting tooth 4 and the interlock of socket latch, and the realization latch is connected with socket.

In socket 7 during the plug pin, by pinching upper and lower scissor handle 2, compression clamp limiting tooth 4 heads within it take in the box structure that latch main body 1 and plug pin cap 6 constitute limiting tooth 4, realize the disengaging of latch and socket 7 along the direction of arrow.When cancelling the power on the handle 2, torsion spring 3 flicks scissor handle 2, and back-moving spring 5 resets limiting tooth 4.

Claims

1, a kind of formula pin socket device of pinching comprises that both sides are provided with socket of latch (7) and latch, is characterized in that: latch comprises a box structure by latch main body (1) and plug pin cap (6) formation that cooperates with this socket (7); These box structure front end both sides are provided with reducible limiting tooth (4), and the both sides, rear end are provided with the scissor handle (2) that this limiting tooth (4) is shunk.

2, a kind of formula pin socket device of pinching according to claim 1, it is characterized in that: two head part of described scissor handle (2) are not entangled two heads of limiting tooth (4), and rotating shaft is provided with the torsion spring (3) that scissor handle (2) is resetted; Limiting tooth (4) is fixed in separately the rotating shaft, and its afterbody is provided with the back-moving spring (5) that makes its clamping.
