Description
Technical field
The present invention relates to the security door technical field, especially relate to a kind of prized up-proof door.
Background technology
For safety, consider, security door is widely universal.Usually, security door includes doorframe, door core and lockset, and this lockset is provided with dead bolt, and this doorframe is provided with the lockhole matched with dead bolt.Due to the enhancing day by day of doorframe and the door strength of materials that core adopts, and lockset is day by day accurate, and the anti-theft feature of security door is greatly improved.But, when lawless people, by instruments such as crowbars, stretch into by force in the gap of a core and doorframe, do violence, very likely pry open this security door, thereby safety is had a greatly reduced quality.
Summary of the invention
The purpose of this invention is to provide a kind of prized up-proof door, it has stronger pick-proof ability, thus the high characteristics of safety.
To achieve these goals, the technical solution adopted in the present invention is: prized up-proof door comprises doorframe, door core and lockset, and this lockset is provided with dead bolt, this doorframe is provided with the lockhole matched with dead bolt, and the end of described this dead bolt is provided with annular draw-in groove, and this doorframe is the sheet metal preparation.
The thickness d that is positioned at the sheet metal at lockhole place on described doorframe is: 1.5mm≤d≤5.0mm.
Described this doorframe is provided with anti-kerve, and this core is provided with anti-pulling buckle, and should prevent that kerve and anti-pulling buckle fastened mutually.
The advantage that compared to the prior art the present invention had is: have stronger pick-proof ability, thereby safety is high.Prized up-proof door of the present invention has improved the pick-proof ability of this prized up-proof door from following two aspects.1 that is:, the end of dead bolt is provided with annular draw-in groove, doorframe takes to have the sheet metal preparation of suitable thickness.Like this, even if lawless people can stretch into the gap between a core and doorframe by force by crowbar, can cause the distortion of lockhole, thereby the sheet metal of the formation lockhole after distortion is stuck in draw-in groove, doorframe and dead bolt are connected as one, and then crowbar can't be played a role.2, the anti-pulling buckle on the anti-kerve on doorframe and door core fastens mutually.Like this, door core and doorframe form similar attacker's structure, can effectively resist the power along door core in-plane that crowbar applies, and then have reduced the probability that door core and doorframe are pried open.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is that A-A of Fig. 1 is to view;
Fig. 3 is the B section enlarged drawing of Fig. 2;
Fig. 4 is the vertical view cutaway drawing that a core, doorframe and dead bolt coordinate.
The specific embodiment
Embodiment, see shown in Fig. 1 to Fig. 4: prized up-proof door comprises doorframe 10, door core 20 and lockset.Wherein, this lockset is provided with dead bolt 30, and this doorframe 10 is provided with the lockhole 11 matched with dead bolt 30.That is, dead bolt 30 stretches out in rear insertion lockhole 11, can be by this prized up-proof door locking.In the present invention, the end of this dead bolt 30 is provided with annular draw-in groove 31, and this doorframe 10 is the sheet metal preparation.Like this, lawless people stretches into the distortion that crowbar in the gap between a core 20 and doorframe 10 can cause the sheet metal that forms lockhole 11, thereby the sheet metal that forms lockhole 11 can be stuck in draw-in groove 31, doorframe 10 and dead bolt 30 is connected as one, and then make crowbar can't continue to play a role.
Optimize, the thickness d that is positioned at the sheet metal at lockhole 11 places on this doorframe 10 is: 1.5mm≤d≤5.0mm.The sheet metal of this thickness, both can make doorframe 10 have enough intensity, and can be stuck in preferably in draw-in groove 31.Certainly, the width of this draw-in groove 31 should be a bit larger tham the thickness of this sheet metal.
Further, this doorframe 10 is provided with anti-kerve 12, and this core 20 is provided with anti-pulling buckle 21, and should prevent that kerve 12 and anti-pulling buckle 21 fastened mutually.That is, after this prizing-resistant door closure, anti-kerve 12 and anti-pulling buckle 21 form similar attacker's structure, thereby can effectively resist the power along door core 20 in-planes that crowbar applies, and then have reduced the probability that door core 20 and doorframe 10 are pried open.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
