Fig. 2 is the A-A structural representation partly that the utility model embodiment provides;
Wherein: 11-door body, the 12-doorframe, the 13-hinge leaf, the 14-weather strip, 15-operates handwheel, pricks head in the 16-, 17-center interlock master gear, 18-driven gear, 19-master connecting-rod, 20-side connecting rod, the anti-riot observation port of 21-, 111-door-plate, 112-sealing plate.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As depicted in figs. 1 and 2, the concrete structure of the mine refuge chamber explosion proof door that the utility model embodiment provides is:
Mine refuge chamber explosion proof door specifically comprises a body 11 and doorframe 12; One side of door body 11 is connected on the doorframe 12 through hinge leaf 13; Door body 11 inside have cavity, are filled with heat-barrier material in this cavity, and doorframe 12 is equipped with weather strip 14 with the joint portion of door body 11; On the door body 11 two hand wheels 15 are installed, lay respectively at the inside and outside both sides of a body 11;
The side connecting rod 20 that aforementioned link mechanism is provided with center interlock master gear 17, driven gear 18, the master connecting-rod 19 that is connected with driven gear 18 and is connected with master connecting-rod 19, the interior bundle of side connecting rod 20 connections 16, it is concrete be appreciated that for:
Linkage comprises center interlock master gear 17, and this center interlock driving gear 17 is stirred driven gear 18, and this driven gear 18 connects drive master connecting-rod 19, and this master connecting-rod 19 is connected with side connecting rod 20, and the end of this side connecting rod 20 is connected with interior dog 16.
In the utility model embodiment, side connecting rod 20 ends are connected with 8 interior dogs 16, about each three; Each one up and down; The lockhole of the setting of relevant position also has 8 on the doorframe 12, is merely a specific embodiment of the utility model at this, not in order to restriction the utility model.
In the utility model embodiment, door body 11 is provided with door-plate 111 and sealing plate 112, sees also Fig. 2, and Fig. 2 has provided the connected mode of door body 11 with doorframe 12, is provided with weather strip 14 between door-plate 111 and the doorframe 12.
Wherein, this door-plate 1 can be set to be male type, and like this, the cavity between door-plate 111 and the sealing plate 112 is bigger, and the heat-barrier material of filling is more, anti-riot better effects if.
