Description
One, technical field
The utility model relates to a kind of security door.
Two, background technology
At present, the security door of selling on the market, because simple in structure, the lock dot structure is unreasonable, a little less than the scrap (bridge) of door leaf is highly brittle, is very easily pried open, and therefore has very big potential safety hazard.
CN2423390 discloses a kind of security door of improved tool erosion control sled function, and it can effectively prevent crack that pry pours edge protection and doorframe with the edge protection turnup, and then inserts crack between a door and its frame, thereby effectively realizes tamper-resistant function.Feature is that its edge protection end has flanging (button limit), and the doorframe corresponding positions is equipped with the groove that cooperates with flanging.And can in groove, establish embeding locking gate port by the sidewall near door leaf.Pry is difficult to insert in the edge protection, pry is forced to pour, or flanging by the cell wall of doorframe upper groove even at the cost of one's life; Or the flanging distortion forms the locking shape with embeding locking gate port.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of security door with two pick-proof structures.
The utility model is achieved through the following technical solutions: a kind of security door with two pick-proof structures, the door leaf that comprises band door skin (1) and door leaf backboard (2), the doorframe that contains hinge side's housing (3) and lock side's housing (4), hinge side at door leaf and doorframe, the hinge (5) that connects door leaf and doorframe is housed, lock side at door leaf and doorframe, but the lockset (6 of locking door leaf and doorframe is housed, 7), it is characterized in that: lock side in door skin (1), be provided with one or more button edge strips (8,9), be provided with and detain edge strip (8 in the corresponding position of lock side's housing (4), 9) the button limit groove (13 that matches, 14).Button edge strip (8,9) generally has two to get final product.Button available thick steel band roll forming of edge strip (8,9) and door leaf backboard (2) weld together with the junction and/or door skin (1) flanging of door skin (1), like this than directly much higher with the button limit intensity of door skin (1) bending formation.
Further scheme is: have the dead bolt hole that cooperates with the dead bolt of lockset (6,7) on button edge strip (8,9).Be that dead bolt not only cooperates with dead bolt hole on lock side's housing (4), but also with door skin (1) on button edge strip (8,9) on dead bolt hole cooperate, so form dual lock structure, also promptly two pick-proof structures.Generally speaking, when door leaf has the limit lock or be called (secondary lock) lockset (7), the dead bolt that only need be designed to (secondary lock) lockset (7) and button edge strip (8,9) the upward dead bolt hole of corresponding position cooperate and get final product, when button edge strip (8,9) has when several, only need open dead bolt hole and get final product in the corresponding position on the button edge strip of the most close door leaf.So design has been enough to satisfy antitheft requirement.
Further scheme is: be provided with boss (11) in the hinge side of door leaf backboard (2), be provided with the groove (10) that matches with boss (11) in the corresponding position of hinge side's housing (3).This structure has also played good pick-proof, sound insulation and insulation effect.
Hinge side described in the utility model is meant the hinge connection side, and described lock side is meant the sealed side of lockset.
Advantage of the present utility model: door is when closing, and dead bolt not only cooperates with dead bolt hole on the lock side housing, but also with door skin on the button edge strip on dead bolt hole cooperate, the dual lock structure of formation like this is enough to satisfy antitheft requirement.The boss of door leaf hinge side also buckles in the groove on the doorframe and when adding sealing joint strip, has further played good pick-proof, sound insulation and insulation effect.
Four, description of drawings
Fig. 1 is the schematic cross-sectional view of embodiment of the present utility model.
Fig. 2 is the I district enlarged drawing of Fig. 1.
Among the figure: the 1-door skin, 2-door leaf backboard, the 3-side of hinge housing, the 4-side of lock housing, the 5-hinge, 6-(main lock) lockset, 7-(secondary lock) lockset, 8-detains edge strip, and 9-detains edge strip, 10-groove, 11-boss, 12-sealing joint strip, 13-button limit groove, 14-button limit groove.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
As Fig. 1, a kind of security door with two pick-proof structures, the door leaf that comprises band door skin 1 and door leaf backboard 2, the doorframe that contains hinge side's housing 3 and lock side's housing 4, hinge side at door leaf and doorframe, the hinge 5 that connects door leaf and doorframe is housed, lock side at door leaf and doorframe, but the main lock lockset 6 of locking door leaf and doorframe is housed, secondary lock lockset 7, junction, lock side at door skin 1 and door leaf backboard 2 and door skin 1, be welded with the promptly high button edge strip 8 of two buttons of one high and one low edge strip with thick steel band roll forming, short button edge strip 9 is provided with and high button edge strip 8 in the corresponding position of lock side's housing 4, the button limit groove 13 that short button edge strip 9 matches, 14.On height button edge strip 8, have the dead bolt hole that cooperates with the dead bolt of secondary lock lockset 7.The dead bolt of promptly secondary lock lockset 7 not only cooperates with dead bolt hole on the lock side housing 4, but also with door skin 1 on height button edge strip 8 on dead bolt hole cooperate, form dual lock structure, also be pair pick-proof structures.So design has been enough to satisfy antitheft requirement.
Hinge side at door leaf backboard 2 is provided with boss, is provided with the groove 10 that matches with boss 11 in the corresponding position of hinge side's housing 3, also is embedded with sealing joint strip 12 between door leaf backboard 2 and doorframe, and this structure has also played good pick-proof, sound insulation and insulation effect.
When the gap location of forming when housing and short button edge strip 9 is subjected to external force and prizes, 3 stressed (two the strong point and the external force pressure spot between two strong points) have reached equilibrium of forces on the secondary lock lockset 7, unless pair lock lockset 7 dead bolts are fractureed, otherwise door is prized not opened.This is a design core of the present utility model.On the other hand, the groove 10 that matches with boss 11 that establish the pick-proof boss 11 establishing in the hinge side of door leaf side (being hinge edge) and the corresponding position of housing 3 closes behind the door, and the pick-proof boss 11 on the door leaf buckles in the groove 10, has formed another road pick-proof barrier.
