Abstract

The utility model relates to a trailing-proof compartmentation safety door, comprising a thick door frame and an inner and an outer door connected with the frame. An interlocking unit between the two doors is fixed on the door frame. The distance between the two doors is over 500mm. With the utility model, people entering the door can not be bitten, which is convenient to user; the interlocking unit between the two doors is a flexible interlocking unit. The utility model has the advantages of simple construction, stable performance, convenient operation and wide application, and can be used as the trailing-proof compartmentation safety door or the trailing-proof following device for the counter.

Description

The anti-partition safety door of trailing

Technical field: the utility model relates to a kind of anti-safety door of trailing.

Background technology: at present, domesticly widely usedly anti-ly trail distance between partition door two sects all less than 490MM, though have the anti-function of trailing, because the short phenomenon that the folder people often occurs of the distance between two sects is brought multiple inconvenience to the user.Simultaneously, the interlock between two sects also exists multiple deficiency; The frame for movement more complicated, long hook frequent impact in the fond of gossip and mechanism on the door, yielding wearing and tearing misplace or do not contact, simultaneously, mechanical interlocked mechanism adds inserted sheet by connecting rod and forms, and self intensity and rigidity are had relatively high expectations, if transportation, installation make a body deformability, mechanical interlocked mechanism will often be out of order, and the electronic lock cost is higher, and addressing these problems becomes urgent need.

The utility model content: the technical problems to be solved in the utility model provides a kind of anti-partition safety door of trailing of simple in structure, easy to use, reliable operation, anti-trailing cut off the interior external door that safety door comprises thick body doorframe and connection, distance between two sects is greater than 500MM, is fixed on doorframe and is provided with interlock between two sects.The utility model since the distance between two sects greater than 500MM, therefore the person of entering enters the phenomenon that can not produce the folder people in the safety door, has made things convenient for the user; Soft interlock is therefore simple in structure because the interlock between two sects adopts, reliable operation, easy to use suitable.

Description of drawings:

Fig. 1 is the utility model front view; ,

Fig. 2 is the vertical view of Fig. 1;

The specific embodiment: as shown in the figure, anti-trail cut off that safety door comprises thick body doorframe 1 and interior external door 2, two sects that connect between distance greater than 500MM, be fixed on doorframe and be provided with interlock between two sects.Interlock is novel soft interlock, comprises that the end that is equipped with between the door bolt 4 at the rotation door-hinge 3 that is contained in a sect and another sect passes through bracing frame 5 by bracing frame 5 with the other end that rotates lacing wire 6 that door-hinge links to each other, lacing wire and links to each other successively with back-moving spring 8, locked inserted sheet 7.

The course of work of this device is: when first sect is advanced after the people shuts, then the door-hinge at first sect is owing to inwardly rotate then this lacing wire cable wire of pull, in succession on the lacing wire cable wire locked inserted sheet of door bolt at second sect, lacing wire cable wire one is twitched then, and this inserted sheet leaves door bolt, second sect is because no door bolt is locked, then can easily open, and when the people opens second sect, because the inserted sheet of another lacing wire cable wire natural relaxation this lacing wire cable wire under the effect of return spring is inserted the door bolt at first sect dead rapidly again, so be all the time two sects you open my and close, I open you closes, anti-trailing, the anti-tracking.

Claims

1. anti-trail the partition safety door for one kind, comprise thick body doorframe and connect thereon interior external door, be fixed on doorframe and be provided with interlock between two sects, it is characterized in that: the distance between two sects is greater than 500MM.

2. the anti-partition safety door of trailing as claimed in claim 1, it is characterized in that: being fixed on the interlock that doorframe is provided with between two sects is soft interlock, it comprise the end that is equipped with between the door bolt at the rotation door-hinge that is contained in a sect and another sect and rotate the lacing wire that door-hinge links to each other, the other end of lacing wire links to each other with back-moving spring, locked inserted sheet successively by bracing frame.
