Abstract

A security door that is made with the doorframe post into a whole is characterized in that: a convex plate is arranged at the junction of the door and the doorframe post, while correspondingly a flute is arranged on the doorframe post; both of the convex plate and the flute are mutually corresponded; an auxiliary lock tongue (2) is arranged in the doorframe post (1) which is near the door panel (4), one end of which is contacted with a main lock tongue (6); when the door is closed, the lock tongues are respectively threaded through the convex plate that is arranged on the doorframe post and the door to bolt both of the doorframe post and the door into a whole. As a gap between the door and the doorframe cannot be found from the outside of the door, the security door can effectively prevent picklock from occurring. In addition, the door and the doorframe are organically combined into a whole so as to effectively prevent the door from bumping open. Even if the auxiliary lock tongue is destroyed by hard object, the main lock tongue will not be influenced so as to greatly improve the burglarproof performance.

Description

The security door that can be integrated with doorframe column

Technical field

The utility model relates to a kind of door, especially the security door that can be integrated with doorframe column.

Background technology

For preventing that sled from surreptitiously entering the room, present door mainly is to realize by the security performance that improves lock, as the safety anti-theft lock of dual fail-safe, three insurances, four insurances, five guarantees danger.Adorned the door of this safety lock, improved people's the sense of security, the sled that prevents the robber has surreptitiously been entered the room played certain effect of controlling.But this door also has certain deficiency, general door, and door directly intersects with doorframe, can effectively find the slit between door and doorframe from the outside, as long as just can directly destroy main lock with hard thing, door has just been opened when main lock is ruined; In addition, lock connects with adopting screw being connected of door mostly, if collide with sudden force, screw is difficult to bear stronger impact force and is rushed open, and therefore, is difficult to effectively prevent that burglar from taking place.

Summary of the invention

The purpose of this utility model is to provide a kind of security door that can be integrated with doorframe column that not only can prevent effectively that hard thing from prying open and can effectively prevent to rush open.

The purpose of this utility model can reach by following technical measures, that is: this security door that can be integrated with doorframe column, comprise door and doorframe, its key is: the junction with doorframe column on door is provided with boss, corresponding with it, the column of this doorframe is provided with groove, and the two agrees with mutually; Near in the doorframe column of door-plate secondary dead bolt is being housed, this pair dead bolt one end contacts with main dead bolt; During locking, secondary dead bolt passes respectively under main dead bolt promotes in the boss set on doorframe column and the door, and both door bolts are one.

Described door is the gusset that has covered " L " shape on door-plate.This is the intensity for reinforced door, and door covers with the gusset of " L " shape on the door-plate of other material and makes, and the another side that does not also repel at plate covers a block plate certainly; If intensity that should reinforced door, simultaneously from saving steel, reducing cost can be in the joint portion of door-plate near doorframe column, dress lastblock cross section is the channel-section steel of " П " shape.Used like this channel-section steel exterior surface area is far smaller than the area of door-plate, also is convenient on common door, install, so broad market prospect.

The beneficial effects of the utility model are: from not finding the slit between door-plate and doorframe outdoors, can effectively prevent the generation of picking lock.In addition, door-plate and doorframe column are organically integrated, and can prevent the possibility that a quilt rushes open effectively, even if secondary dead bolt is destroyed by hard thing, but do not influence main dead bolt, have greatly improved anti-theft capability.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1, also be first kind of embodiment of the present utility model, and this figure has mainly expressed gusset with " L " shape and covered the situation that the door-plate made on the door-plate of other material combines with doorframe column;

Fig. 3 also is the A-A sectional view of Fig. 1, it is second kind of embodiment of the present utility model, this figure has mainly expressed in the door-plate 4 of other material joint portion near doorframe columns 1, and the situation that door-plate that channel-section steel 5 that a cross section is " П " shape makes combines with doorframe column is housed.

The specific embodiment

Below with reference to accompanying drawing concrete structure of the present utility model is further described.

Referring to Fig. 1, Fig. 2, Fig. 3, the security door that can be integrated with doorframe column described in the utility model comprises door and doorframe, its key is: the junction with doorframe column 1 on door is provided with boss, corresponding with it, the column of this doorframe is provided with groove, and the two agrees with mutually; Near in the doorframe column 1 of door-plate 4 secondary dead bolt 2 is being housed, these pair dead bolt 2 one ends contact with main dead bolt 6; During locking, secondary dead bolt 2 passes respectively in the boss set on doorframe column 1 and the door under main dead bolt 6 promotes, and both door bolts are one.Outside described secondary dead bolt 2, be set with spring.

As shown in Figure 2: described door is the gusset 3 that has covered " L " shape on door-plate 4.Design is "T"-shaped at " L " z bend place, so that cannot see the slit between " L " minor face and the doorframe column.Even if thief's picking lock also can only damage secondary dead bolt 2, main dead bolt 6 can not damage.When owner opened the door, main dead bolt 6 was return in the door-plate 4, and secondary dead bolt 2 is return because of main dead bolt 6 and got back near in the doorframe column of door-plate 4, and gusset 3 leaves doorframe column 1 in company with door-plate 4 rotations.

As shown in Figure 3: described door is in the joint portion of door-plate 4 near doorframe column 1, and the channel-section steel 5 that a cross section is " П " shape is housed.The bipod of " П " is uneven in length, and its long limit is close on the door-plate 4, in the groove of the column 1 of minor face insertion doorframe, near in the doorframe column 1 of door-plate 4 secondary dead bolt 2 is being housed, and these pair dead bolt 2 one ends contact with main dead bolt 6; Secondary dead bolt 2 passes the bipod and the doorframe column 1 of " П " from door-plate 4.When opening the door, secondary dead bolt 2 returns in the door-plate 4 because of main dead bolt 6, and gets back in the close doorframe column 1 of door-plate 4, and channel-section steel 5 leaves doorframe column 1 with door-plate 4 rotations.
