The theft-proof efficacy is achieved.

Description

Theftproof door

The utility model relates to a kind of improved door, particularly a kind of door with anti-theft effect.

General at present structure, mostly as shown in Figure 1, in the default aperture of door of wall 1 ', fixing doorframe 2 ', door leaf 3 ' is articulated in the doorframe 2 ' with hinge 4 ', door leaf 3 ' is that the realization switching function is rotated in the axle center with hinge 4 ', for preventing that the purlonier from entering, at the medial surface 32 ' of door leaf 3 ' and the intersection of doorframe 2 ', installing lockset 5 ', though the manufacturing technology and the anti-theft effect of lock are improved day by day, but still the destruction that can't effectively prevent the deathwatch traces it to its cause, and the structure of non-lock is not good at, but the design that is door leaf does not have good concealed structure, causes the destruction door leaf can open door lock easily.As shown in Figure 2, lateral surface 31 ' the majority of general door leaf 3 ' is to extend in parallel out a catch 33 ', and when at closing time, door leaf 3 energy closings are on the frame face of doorframe 2 ', form door leaf 3 ' lateral surface 31 ' and can constitute the shop front of a sealing, and promote attractive in appearance with catch 33 '.For keeping the normal rotation of door leaf 3 ', door leaf 3 ' must be established one with doorframe 2 ' and cooperate space 7 ', this is the big defective of one on the general door, because general door leaf 3 ' lateral surface 31 ' can't hiddenly effectively completely cut off this space 7 ', so that can impose external force 6 ' and locate to pry open catch 33 ' from doorframe side bumper sheet 33 exposed ora terminalis 331 ', and form exposing of space 7 ', so that space 7 ' is destroyed since then, open door lock 5 ' and be mounted on equally that medial surface 32 ' is gone up and the anti-theft device of the keeper that can not open by the external world, chain lock and so on, home safety is threatened.

The purpose of this utility model is that a kind of improved door with anti-theft effect will be provided, and it can cover the space between door leaf and doorframe effectively, pries open destruction to prevent external force.

The utility model is achieved in that on the vertical long limit of lateral surface installing lockset one side of door leaf, extend one and cover the arc block plate in space between door leaf and doorframe, when door leaf cuts out, catch and the tight closing of the doorframe that identical arcwall face is arranged, the center of arc of arc block plate is on the direction of door leaf medial surface, the ora terminalis that forms catch inserts the doorframe side deeply, the extended catch of while door leaf, and its interior angle place is provided with the reinforcement edge.

The utility model only changes structural shape in a side of door and doorframe dress lockset, and simple in structure, its arc block plate ora terminalis inserts in the doorframe side deeply and catch is established the reinforcement edge, can prevent effectively that external force from prying open destruction.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof

Fig. 1 is general door and sash structure sectional elevation.

Fig. 2 is that Fig. 1 structure door leaf extends the ruined action schematic diagram of catch.

Fig. 3 is according to a kind of concrete structure axonometric drawing that the utility model proposes.

Fig. 4 is the sectional elevation of Fig. 3 structure.

With reference to Fig. 3,4, door leaf 1 is connected on the doorframe 4 that is fixed on wall 3 with hinge 2, the lateral surface 12 of door leaf 1 with the vertical long limit of lockset 5 homonymies on, extend an outwards outstanding circular arc catch 13, the center of arc of catch 13 is on door leaf 1 medial surface 11 directions, catch 13 extending end ora terminalis 131 with the change of tangential direction on the arc surface towards medial surface 11 directions of door leaf 1, why outer the outside end face 41 that doorframe 4 contacts with catch 13 also matching design outstanding arc surface, can contact with doorframe 4 tight closings when door leaf 1 cuts out.The door that complements each other to form by above-mentioned door leaf 1 and doorframe 2; the ora terminalis 131 of its catch 13 is towards door leaf 1 medial surface 11 directions; and insert the side of doorframe 4 deeply; airtight and can not be to form one by the ora terminalis 131 of outside destroy; therefore; can complete hidden protection door leaf 1 and 4 formed spaces 7 of doorframe; with prevent external force from the space 7 pairs be installed in that lockset 5 destroys on the medial surface 11; thereby give full play to anti-theft effect; in addition for strengthening the structural strength of catch 13; establish a reinforcement edge 14 at lateral surface 12 with the interior angle place that is connected of extending catch 13,, extend the defective that catch 13 may produce strength deficiency to mend to strengthen interior angle intensity.Said structure can be protected the lockset 5 of medial surface 11, guarantees home safety, is an economic practical design.

Claims (2)

1, one by door leaf (1), hinge (2), doorframe (4), the door that lockset (5) is formed with anti-theft effect, it is characterized in that installing on the vertical long limit of lockset (5) one sides at the lateral surface of door leaf (1), extend one and cover the arc block plate (13) in space (7) between door leaf (1) and the doorframe (4), in door leaf (1) arc block plate (13) and tight closing of the doorframe that identical arcwall face is arranged (4) when closing, the center of arc of arc block plate (13) is on the direction of door leaf (1) medial surface (11), and the ora terminalis (131) that forms arc block plate (13) inserts the side of doorframe (4) deeply.

2, door according to claim 1 is characterized in that at door leaf (1) lateral surface (12) and extension circular arc, the connection interior angle place of catch (13) establishes one and strengthens edge (14).
