CN2249811Y - Safety door - Google Patents

Abstract

The utility model relates to a safety door. A door body of the safety door is composed of an outer door plate and an inner door plate, wherein, the transversal length of the outer door plate is larger than the length of the transversal inner edge of a door frame, and one side of the inner door plate is hinged with the upper and the lower edges of the door frame; sliding and coupling devices mutually matched can be arranged between the inner and the outer door plates, and a lock stop mutually matched are arranged between the inner and the outer door plates. When the lock is matched with the lock stop, both sides of the transverse direction of the outer door plate are positioned on the inner side of the door frame, and the outer door plate can not move corresponding to the inner door plate. When the lock is disengaged from the lock stop, the outer door plate can move corresponding to the inner door plate through the sliding and coupling devices; the outer door plate can stop moving when one side of the outer plate exposes out of the door frame, and the outer door plate and the inner door plate can be opened together. The utility model has the advantages of good theft-proof performance and simple structure.

Description

Security door

The utility model relates to a kind of security door, relates in particular to a kind of can be used at home and the security door of various safes.

The various security doors that are used for house and safe etc. are arranged at present on the market, are flat opening and the plug-type security door described in the utility models such as CN2152055Y, CN2148154Y, CN2164453Y, CN2163223Y as notification number.These security doors all have certain theftproof, but structure is comparatively complicated.

And the purpose of this utility model is to provide a kind of security door that is applicable to house and safe, and it has good theftproof performance, and structure is simpler.

To achieve these goals, the technical solution of the utility model is, a kind of security door, comprise doorframe, the door body hinged with doorframe, be contained in lock and backset on the body, it is characterized in that, the door body is made up of external door panel and internal hilar plate, the lateral length of external door panel is greater than the length of the horizontal inner edge of doorframe, internal hilar plate in a horizontal side by hinge and hinged and rotatable with the both sides up and down of doorframe, slip hookup mechanism and the lock that can cooperatively interact and the backset that can cooperatively interact are housed on external door panel and the internal hilar plate separately so that external door panel can be by described slip hookup mechanism relatively internal hilar plate along laterally to two side shiftings.

When stating technical scheme on the implementation, described slip hookup mechanism can be formed by being loaded on the bearing on the external door panel and being loaded on mounting on the internal hilar plate, that cooperate with described bearing.

When adopting technique scheme, because the lateral length of security door external door panel is greater than the length of the horizontal inner edge of doorframe, when door lock is lived, the both lateral sides of external door panel is positioned at the doorframe inboard, and external door panel can not move relative to internal hilar plate, do not establish hinge on the external door panel, so the criminal is difficult to set about to force open the door in addition; Different because of security door of the present utility model in addition with existing security door, not that the door body is locked on the doorframe, but, the relative position relation of external door panel and internal hilar plate reaches the purpose of locking a door by being locked, so need not adopt the door body is not locked in dead bolt or bolt head on the doorframe, structure is simpler; And because of lock can be installed in optional position on the body, even can be installed in the position beyond the body, as long as can be the locking of the relative position of external door panel and internal hilar plate, so the disguise of locking better, pick-proof be better; And can use lock, for example key lock, coded lock, electronic lock etc. arbitrarily.

Below describe by an embodiment of the present utility model and in conjunction with its accompanying drawing, can clearer understanding be arranged to the purpose of this utility model, feature and effect thereof.

Fig. 1 is the front view of security door of the present utility model when locking-in state.

Fig. 2 is the front view of security door of the present utility model when open mode.

Fig. 3 is the sectional view along A-A line among Fig. 2.

In Fig. 1, the 1st, doorframe, a door body is made of external door panel 2 and internal hilar plate 3, the lateral length of external door panel 2 is greater than the length of the horizontal inner edge of doorframe 1, internal hilar plate 3 in a horizontal side (right side among the figure) by hinge 6 and hinged with the both sides up and down of doorframe 1.Bearing 4 is equipped with in the inboard of external door panel 2, and the mounting 5 that can cooperate with this bearing 4 is housed in the relevant position of internal hilar plate 3, and external door panel 2 and internal hilar plate 3 link mutually by bearing 4 and mounting 5.Lock 8 is housed in the inboard of external door panel 2 in addition, is equipped with and locks 8 backsets that cooperate 7 with this in the relevant position of internal hilar plate 3.The 9th, be located at the door shelves of doorframe inboard.As shown in Figure 1, when lock 8 cooperates with backset 7, when security door of the present utility model is in locking condition, the both lateral sides of external door panel 2 is positioned at the inboard of doorframe 1.

As shown in Figure 2, when lock 8 breaks away from backset 7, external door panel 2 can relative internal hilar plate 3 slides to hinge direction (right side among the figure) with mounting 5 by bearing 4, expose outside the doorframe until one side of external door panel 2, this moment can be as shown in Figure 3, external door panel 2 is outwards rotated by hinge 6 together with internal hilar plate 3, thereby a body is outwards opened.In the time will living door lock, as long as door body forced back, and make external door panel 2 relative internal hilar plates 3 and (left side among the figure) slip in the opposite direction, above-mentioned one side until external door panel 2 enters in the doorframe, lock then, lock 8 is cooperated with backset 7, this moment external door panel 2 just can not be again by bearing 4 with mounting 5 and 3 slips of relative internal hilar plate, pinned reliably.

In the present embodiment, be external door panel 2 and internal hilar plate 3 to be linked with bearing 4 and mounting 5, also can utilize other carriages to link certainly, as guide rail, roller etc.

Claims (2)

1. security door, comprise doorframe, with doorframe hinged the door body, be contained in lock and backset on the body, it is characterized in that: the door body is made up of external door panel and internal hilar plate, the lateral length of external door panel is greater than the length of the horizontal inner edge of doorframe, internal hilar plate in a horizontal side by hinge and hinged and rotatable with the both sides up and down of doorframe, slip hookup mechanism and the lock that can cooperatively interact and the backset that can cooperatively interact are housed on external door panel and the internal hilar plate separately so that external door panel can be by described carriage relatively internal hilar plate along laterally to two side shiftings.

2. security door according to claim 1 is characterized in that, described slip hookup mechanism is formed by being loaded on the bearing on the external door panel and being loaded on mounting on the internal hilar plate, that cooperate with described bearing.
