Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model is further described.
The security lock arrangement of this protective airtight partition door, be connected with the hermatic door 1 being arranged in subway tunnel, comprise the casing 2, the first clamping device 3 and the second clamping device 4 that are placed in hermatic door one side, the first clamping device 3 is fixedly installed on the side of hermatic door 1, the one side that casing 2 is relative with hermatic door side is provided with that opening 21, the second clamping devices 4 are arranged in casing 2 movably and is relative with the first clamping device 3 by opening 11; As shown in Figure 1, the first clamping device 3 is respectively equipped with corresponding occlusal surface 34 with the second clamping device 4, and interlock occurs in the time that both contact with each other.
Owing to having adopted, occlusal surface 34 makes that the first clamping device and the second clamping device have overcome that conventional point contacts, plane contact or sphere-contact institute inevitably a hermatic door rock by a small margin problem, occlusal surface can adopt uniform male and fomale(M&F), also can adopt intermeshing tooth bar face as shown in Figure 1, as long as can guarantee that between the first clamping device and the second clamping device, contradicting each other of multiple dimensions guaranteed the stable of hermatic door.
The second clamping device 4 comprises the voussoir body 41 and the guide rod 42 that are fixedly connected sequentially, and the both sides of voussoir body are provided with domatic 43; In casing, be arranged with the left voussoir 5 and the right voussoir 6 that are positioned at the second clamping device both sides, on left voussoir, right voussoir respectively with the domatic consistent driving domatic 56 of the second clamping device both sides, in the time of left voussoir, right voussoir move toward one another, drive domatic 56 to push and order about the second clamping device 4 and move to the first clamping device 3 from both sides to being positioned at domatic 43 the second clamping device 4; Guide rod 42 is plugged on the pilot hole 22 being positioned on corresponding casing 2 walls, guarantees that the moving direction of the second clamping device 4 in casing 2 is consistent.Guide rod 42 passes one end that pilot hole is positioned at casing outside and is fixedly installed baffle plate 44, one springs 45 and is set on guide rod 42 and elasticity connects baffle plate and corresponding cabinet exterior.
Drive the mode of two object move toward one another a lot, and the scissors fork structure that form hinged such as two rod members middle parts, tightens up two rod members and is positioned at two ends of scissors fork structure one side, and the other end of two rod members is drawn close mutually; Inconvenience is installed and the utility model needs manpower to drive to guarantee and can not rely on supply of electric power to bring into play at any time emergencing action but consider that scissors fork structure is on-the-spot, the utility model has adopted as follows comparatively labour-saving structure as driving.
The interior leading screw 7 being rotatably provided with perpendicular to the second clamping device moving direction of casing 2, leading screw 7 is provided with the screw thread that rotation direction is contrary, and left voussoir 5, right voussoir 6 are in transmission connection with leading screw 7 by the screwed hole (not shown in FIG.) adapting with corresponding screw thread respectively; When leading screw 7 rotates, left voussoir 5, right voussoir 6 move in opposite directions or dorsad.Worm gear in leading screw 7 and a worm screw case 8 is in transmission connection by screw thread, and worm screw case is provided with the manual pulley 81 being connected with its inner worm screw.Owing to having adopted worm screw box structure, the utility model can be driven comparatively effortlessly to the second clamping device by left voussoir, right voussoir.
The utility model can be connected with the lower side of hermatic door, now casing of the present utility model is arranged on subway tunnel, in limiting that hermatic door is vertical to turn degree of freedom, hermatic door is played to supporting role, although itself has auto-lock function feed screw nut pair, but consider in order to prevent that screw pair lost efficacy under weight, on casing, be provided with square cotter hole (not shown in FIG.), in square cotter hole, be plugged with voussoir body and be positioned at the square cotter 9 that the end face of casing contacts, after preventing screw pair inefficacy when increasing by the second clamping device stress point, the utility model loses corresponding function.Equally, the utility model also can be used for longitudinal side of hermatic door, and now the utility model does not bear the weight of hermatic door, can meet instructions for use without square cotter is set.
