Abstract
The utility model relates to a theftproof door which comprises a locking mechanism and a connecting rod which are arranged inside a door leaf, wherein one end of the connecting rod is connected with a driving mechanism. The utility model is characterized in that the other end of the connecting rod is connected with the hook head type locking mechanism, and a hook head of the locking mechanism is a C-shaped structure; one end of the hook head is a fixed end, and the other end is a movable end; an assembly structure of a connecting pin arranged inside a slideway is used between the hook head and the connecting rod. The connecting rod is driven by a driving device, such as a door lock, to move to the circumference of the door leaf upwards, downwards, leftwards and rightwards the connecting pin moves inside the slideway to drive the movable end of the hook head to rotate around a fixed pin of the hook head. The hook head rotates around the fixed pin of the hook head, and simultaneously, the hook head can follow the connecting rod to move up and down so that a locking hole on a door frame can be tightly locked or loosened. The assembly structure of the slideway and the connecting pin is used between the hook head and a driving rod of the theftproof door, the structure of the driving mechanism becomes simple, the manufacturing cost of the theftproof door can be reduced, the installation and the maintenance are convenient, and the whole theftproof performance of the theftproof door can be improved.
Description
[technical field] the utility model relates to a kind of security door, belongs to the used window technology field of building.
[background technology] existing security door kind has many kinds, but its locking mechanism is arranged on and mostly is the straight cutting pole structure in the door leaf greatly.Straight cutting pillar locking mechanism links by driving mechanism and door lock, and locking holes is arranged on the doorframe.Owing to be subjected to the restriction of straight cutting pillar locking mechanism locking mode, it is more shallow that the straight cutting post inserts sealed some degree of depth of doorframe, and when door leaf or doorframe were deformed to a certain degree under external force, the straight cutting post broke away from from the locking holes of doorframe easily and loses antitheft locking function.Therefore, straight cutting pillar security door exists the locking mechanism design unreasonable, and locking is insecure, shortcomings such as whole strick precaution poor performance.In order to solve the technical problem of above-mentioned existence, ZL99245852.8 utility model patent manual discloses a kind of " security door ", this security door adopts eave tile formula locking mechanism, the locking point that has overcome the existence of straight cutting pillar lock structure is insecure, shortcomings such as whole theftproof performance difference have improved the integral body of security door and have taken precautions against performance.But because the eave tile formula locking mechanism driving mechanism structure complexity of this security door not only increased the security door manufacturing cost, and manufacturing process is unreasonable, assembling and maintenance are very difficult.
Characteristics such as [summary of the invention] the purpose of this utility model is to overcome the shortcoming that above-mentioned prior art exists, and provides a kind of driving mechanism structure simple security door, and this security door adopts eave tile formula locking mechanism, and it is firm to have a locking, and whole theftproof performance is good.
The purpose of this utility model is to realize like this.
A kind of security door, comprise the locking mechanism and the connecting rod that are installed in the door leaf, one end of connecting rod is connected with driving mechanism, the other end that it is characterized in that said connecting rod is connected with eave tile formula locking mechanism, eave tile one end is a fixed end, the other end is a movable end, adopts in the slideway between eave tile and the connecting rod and establishes the connecting pin assembly structure.The eave tile of above-mentioned locking mechanism preferably is C type structure.During use, connecting rod is under the drive of drive unit such as door lock, upper and lower or left and right action around door leaf, connecting pin moves in slideway, the movable end that drives eave tile rotates around its steady pin, make eave tile when its steady pin rotates, can be with the upper and lower action of connecting rod, lock or unclamp locking hole on the doorframe.
The eave tile formula locking mechanism that this security door provided can adopt outer box, drive link and eave tile three parts to form.Outer box is fixedly mounted in the door leaf body, and drive link is connected with connecting rod, is processed with slideway on the drive link, is provided with connecting pin in the slideway.Connecting pin can be installed on outer box or the door leaf body.
Sealed more firm in order to make between door leaf and the doorframe, above-mentioned eave tile formula locking mechanism can adopt two ditch header structures, promptly is provided with two slideways at drive link, and connecting pin is assembled into one with drive link and eave tile.
Security door provided by the utility model, compare with existing eave tile formula safe-guard door lock locking mechanism, adopt slideway and connecting pin assembly structure between its eave tile and connecting rod or the drive link, make the structure of driving mechanism simpler, practical, reduced the security door manufacturing cost, installation and maintenance are very convenient, improved the whole theftproof performance of security door.
[description of drawings] Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is a locking mechanism structure enlarged diagram shown in Figure 1.
Marking explanation: 1, door lock; 2, door leaf; 3, doorframe; 4, reinforcing rib; 5, connecting rod; 6, locking mechanism; 7, drive link; 8, outer box; 9, eave tile; 10, slideway; 11, connecting pin; 12, steady pin.
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
In [specific embodiment] present embodiment, security door comprises reinforcing rib 4, locking mechanism 5 and the connecting rod 4 that is installed in the door leaf 2, one end of connecting rod 4 is connected with driving mechanism such as door lock 1, the other end of connecting rod 5 is connected with eave tile formula locking mechanism 6, the eave tile 9 of this locking mechanism 6 is C type structure, eave tile 9 one ends are fixed end, and the other end is a movable end, adopt in the slideway 11 between eave tile 9 and the connecting rod 5 and establish connecting pin 10 assembly structures.Above-mentioned connecting rod 5 is under the drive of door lock 1, to door leaf 2 upper and lower or left and right actions all around.Above-mentioned connecting pin 11 moves in slideway 10, and the movable end that drives eave tile 9 rotates around its steady pin 12, makes eave tile 9 when its steady pin 12 rotates, can be with connecting rod 5 upper and lower actions, and lock or unclamp locking hole on the doorframe 3.
