It is a kind of in abominable mechanical environment (as vibration, impact, constant acceleration, collision etc.) that the purpose of this utility model is to provide, the plug-type locking device that connection reliability is high.
The purpose of this utility model can realize by following measure:
This plug-type locking device is made up of fixedly connected end and flexible connection end, the groove that one connection usefulness is arranged near the front portion of a side that flexibly connects end on the fixedly connected end, flexibly connect end and comprise shell, connection ball (nail or post), locking element elastic element and barrier element, there is a front that the rectangular slot of chamfering is arranged towards the one side that connects ball on the locking element, on the right side of locking element one boss is arranged, when locking state, rectangular slot is connecting between ball and the locking element.
Advantage of the present utility model is: not only have simple to operate, the little characteristics that take up room of former plug-type locking device, but also have when using in abominable mechanical environment (for example vibrate, impact, constant acceleration, collision etc.) than the high advantage of former plug-type locking device connection reliability.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the locking state sectional view of device described in the utility model;
Fig. 2 is the separated state sectional view of device described in the utility model;
Fig. 3 is the released state sectional view that device described in the utility model flexibly connects end;
The sectional view that Fig. 4 is in the unlocked position for the locking element 4 in the device described in the utility model.
Describe above-mentioned two kinds of plug-type locking device differences on operating principle in detail below in conjunction with accompanying drawing:
Plug-type locking device described in the utility model is when the fixedly connected end 1 that separates needs be connected with the flexible connection end, as Fig. 2, should promote locking element 4 vertically forward to unlocked position, as Fig. 3, make the groove 7 on the locking element 4 move to the top that connects ball 3, and keep this state.Can be inserted into fixedly connected end 1 at the same time and flexibly connect in the end housing 2, when the groove on the fixedly connected end 6 is inserted into the below that connects ball 3, locking element 4 can return to locking state shown in Figure 1 under the effect of elastic element 5, and connection ball 3 is squeezed in the grooves of falling on the fixedly connected end 16, barrier element 8 has stoped further retreating of locking element 4 by the boss 9 on locking element 4 right sides simultaneously.Connect outwards moving of ball 3 because of locking element 4 has stopped fully, make connection ball 3 between fixedly connected end 1 and flexible connection end housing 2, play the effect of obstacle, thereby reached purpose of connecting.
The fixedly connected end that connects locking state when being in as shown in Figure 1 with flexibly connect end need separate the time, should be vertically promote locking element 4 to unlocked position to the direction of fixedly connected end 1, as Fig. 4, the groove 7 on the locking element 4 has moved on to the top that connects ball 3 at this moment.Guaranteeing that locking element 4 is in unlocked position, vertically when the opposite direction of fixedly connected end 1 is drawn shell 2, connecting ball 3 can be squeezed in the groove 7 of locking element 4 in the groove 6 by fixedly connected end 1, connect the effect that ball 3 has promptly lost obstacle this moment, and then the flexible connection end is separated with fixedly connected end, reach the purpose of separation.
For former plug-type locking device, when the fixing use of fixedly connected end, if this device uses in abominable mechanical environment (as vibration, impact, constant acceleration, collision etc.), be in the flexible connection end that connects locking state and will be subjected to deviating from the axial force F of fixedly connected end, under the effect of this power, locking element with flexibly connect end and all can fixedly connected the extreme direction motion to deviating from.When in case locking element is moved to unlocked position in the effect of this power, owing to lost to stop and connected the restriction that ball outwards moves, also promptly lost at this moment the effect of between fixedly connected end and flexible connection end, serving as obstacle so connect ball, under the continuation effect of this power, flexibly connect end and will separate with fixedly connected end.So when existing plug-type locking device used in abominable mechanical environment, reliability was not high.
When the fixing use of the fixedly connected end of plug-type locking device described in the utility model, in abominable mechanical environment (as vibration, impact, constant acceleration, collision etc.), theoretically, flexibly connecting end housing 2 should be equidirectional (when being vibrated, it is equidirectional in suffered power of arbitrary identical moment with locking element 4 to require elastic element 5 must design the proper shell 2 that could guarantee) with locking element 4 in suffered power of arbitrary identical moment.Be subjected to as shown in Figure 4 time spent of doing when being in the flexible connection end that connects locking state towards the axial force F of fixedly connected end 1, shell 2 and locking element 4 all produce to fixedlying connected the trend of end 1 direction motion, even locking element 4 moves to unlocked position to the direction of fixedly connected end 1 under the effect of this power, but flexibly connect end 2 axial forces that also are subjected to towards fixedly connected end 1 this moment, though also promptly this moment, locking element 4 moved to unlocked position, but do not have power that shell 2 is separated with fixedly connected end 1, so the time fixedly connected end with flexibly connect end and can not separate.When the axial force F that deviates from fixedly connected end 1 direction that the flexible connection end that is in the connection locking state is subjected to is as shown in Figure 1 done the time spent, shell 2 and locking element 4 all produce to deviating from fixedlys connected the trend of end 1 direction motion, this moment, locking element 4 can not move to unlocked position to the direction of fixedly connected end 1, connect ball 3 also with regard to can not on move and break away from groove on the fixedly connected end 1, being connected receives 3 still plays obstacle between fixedly connected end 1 and shell 2, this moment fixedly connected end with flexibly connect end and can not separate.So being in when the described in the utility model plug-type locking device that connects locking state uses in abominable mechanical environment theoretically, is impossible separate.Unless simultaneously to locking element 4 implement towards the axial force of fixedly connected end 1 direction with implement to deviate to shell 2 when fixedlying connected the jamming of axial force of end 1 direction, just can make fixedly connected end and flexibly connect end and separate.
This plug-type locking device mainly is applicable to connection reliable lock height when requirement is used in abominable mechanical environment, and requires to connect fast and separate, and little occasion takes up room.For example, require to be used for electric coupler, low-pressure pneumatic and the liquid pipe joint etc. of occasions such as anti-vibration, impact, constant acceleration, collision.
