Air door interlocking reliable operation, it is to avoid cause Air escape branch.
For achieving the above object, the utility model proposes a kind of interlocking safety throttle setting, including weight,
Installation frame, draught line, fixed pulley, hold-down support and interlock, be provided with two in described installation frame
Weight, described weight is cylindrical, and described weight is connected above one end of draught line, above described draught line
Being provided with fixed pulley, the other end of described draught line walks around fixed pulley, and described hold-down support is positioned at installation frame
Center, is provided with interlock in described hold-down support, described interlock includes interlocking bearing pin and several are multiple
Position spring, described interlocking bearing pin is inlaid in hold-down support, and the upper end of described back-moving spring is fixed on interlocking plunger
On axle, the lower end of described back-moving spring is arranged on hold-down support.
As preferably, the lower end interlocking bearing pin is close in the upper end of described weight, and described weight is symmetrically distributed in solid
Determine the both sides of bearing.
As preferably, the number of described back-moving spring is 2, and described back-moving spring is symmetrically mounted on fixing
In seat.
As preferably, the lower section of described interlocking bearing pin is provided with two symmetrical projections, described projection and reset bullet
The upper end of spring is connected, and the cross sectional shape of described interlocking bearing pin is circular, and the two ends of described interlocking bearing pin are hemisphere

As preferably, described hold-down support is provided with a spring fixed seat, and the lower end of described back-moving spring is even
It is connected on spring fixed seat,
The beneficial effects of the utility model: compared with prior art, a kind of interlocking peace that this utility model provides
Full blast door gear, during due to pedestrian by air door, if open two air doors simultaneously, can produce Air escape branch
Problem, by the interlock installed above at weight, is provided with interlocking bearing pin, when air door is beaten in interlock
Opening, the weight on the left side rises, and weight drives interlocking bearing pin to be shifted to the right to the top of the right weight so that the right
Weight can not go up shifting, completes to interlock work, prevents two air doors from opening simultaneously, make twice air door interlocking work
Reliably, it is to avoid cause Air escape branch.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of this utility model a kind of interlocking safety throttle setting；
Fig. 2 is the structural representation of the interlock of this utility model a kind of interlocking safety throttle setting.
[detailed description of the invention]
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below by accompanying drawing and
Embodiment, is further elaborated to this utility model.However, it should be understood that tool described herein
Body embodiment, only in order to explain this utility model, is not limited to scope of the present utility model.Additionally,
In the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring this practicality
