Abstract
The utility model relates to an invisible central control lock of a security door, which is composed of a fixed mounting plate, a plectrum plate, an upper-bolt operation rod, an upper-bolt turn arm, a lower-bolt operation rod and a lower-bolt turn arm. The utility model is characterized in that the fixed mounting plate is composed of a face plate the center of the face plate is opened with a long hole and a mounting plate which is perpendicular to the face plate, the plectrum plate penetrates the long hole of the face plate, one end of the plectrum plate is hinged on the mounting plate, the other end is exposed outside the face plate, one end of the upper-bolt turn arm is hinged on the plectrum plate, the articulated point is disposed between the face plate and the articulated point of the plectrum plate and the mounting plate, the other end of the upper-bolt turn arm is hinged with the lower end of the upper-bolt operation rod, one end of the lower-bolt operation rod is hinged with the end portion of the plectrum plate, and the other end of the lower-bolt operation rod is hinged with the upper end of the lower-bolt operation rod. Because the utility model is installed in a door leaf of the security door, the pushing and the indentation of the upper and lower door bolts can be achieved to accomplish the function of fixing door leaf by toggling the plectrum plate up and down, thereby enabling the utility model to be completely hidden in the door leaf and not to be exposed, and the overall appearance of the security door can not be affected.
Description
Technical field
The utility model belongs to a kind of security door door lock, the stealthy centrally controrlled locking system of particularly a kind of security door.
Background technology
At present the fixedly door leaf in the employed two-door fan security door is by the handle type centrally controrlled locking system door leaf to be fixed on the doorframe by keeper up and down, need rotate the handle that exposes during use and make up and down keeper realize release or indentation and finish the fixedly function of door leaf.This handle type central controlled lock exists handle to expose influences the security door overall appearance.
Summary of the invention
The purpose of this utility model provides and a kind ofly can be arranged on the stealthy centrally controrlled locking system of security door in the door leaf to centrally controrlled locking system, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is by mounting plate, dial plate, on fasten action bars, on fasten connecting lever, under fasten action bars and fasten down the connecting lever formation, be characterized in: mounting plate is panel and perpendicular installing plate formation that central authorities have slotted hole, dial the slotted hole that passes panel of plate, an end of dialling plate is hinged on the installing plate, its other end exposes outside panel, on fasten connecting lever an end dial on the plate with being hinged on, its pin joint is being dialled between plate and installing plate pin joint and the panel, on fasten connecting lever the other end and on to fasten the lower end of action bars hinged; One end of fastening action bars down is hinged with the end of dialling plate, and its other end is hinged with the upper end of fastening action bars down.
Fasten an end that also is hinged with a reset arm on connecting lever and the pin joint of dialling plate on above-mentioned, the other end of reset arm is connected with the installing plate inner edge by an extension spring.
Because the utility model is mounted in the security door door leaf, utilization stir plate about, and make up and down keeper realize release or indentation and finish the fixedly function of door leaf, make the utility model be hidden in the door leaf fully, do not expose, can not influence the overall appearance of security door.
Description of drawings
Fig. 1 is the utility model keeper indentation status architecture schematic diagram up and down.
Fig. 2 is the utility model keeper release status architecture schematic diagram up and down.
Fig. 3 is the utility model panel construction schematic diagram.
Among the figure: 1-dial plate, 1.1-dial plate and installing plate pin joint, 1.2-dial plate and on fasten connecting lever pin joint, 1.3-dial plate with under fasten to fasten on connecting lever pin joint, the 2-to fasten under connecting lever, the 3-to fasten under action bars, the 8-on connecting lever, 4-reset arm, 5-mounting plate, 5.1-panel, 5.2-panel slotted hole, 5.3-installing hole, 6-extension spring, the 7-and fasten action bars.
The specific embodiment
Further describe the utility model below in conjunction with accompanying drawing.
The utility model at first is embedded in mounting plate 5 of the present utility model in the door leaf when mounted, then with upper and lower keeper respectively with of the present utility model on the lower end of fastening the upper end of action bars 7 and fastening down action bars 8 fix, the utility model is fixed on the side of door leaf by the installing hole 5.3 on the panel 5.1 of mounting plate 5.
It is downward that the utility model is stirred plate 1 in use, dialling plate 1 rotates with dialling plate and installing plate pin joint 1.1, fasten connecting lever 2 in the 1 meeting drive of group plate and move down this moment, dialling plate 1 simultaneously fastens connecting lever 3 under can driving and moves up, on fasten connecting lever 2 and fasten down connecting lever 3 drive respectively fasten action bars 7 with under fasten action bars 8 inside indentations, thereby finish the indentation of upper and lower keeper, make upper and lower keeper break away from door leaf, finish the process of opening the door; Stir plate 1 as a same reason upwards, dial plate 1 with dialling plate and upwards rotation of installing plate pin joint 1.1, fasten connecting lever 2 in the 1 meeting drive of group plate and move up this moment, dialling plate 1 simultaneously fastens connecting lever 3 under can driving and moves down, on fasten connecting lever 2 and fasten down connecting lever 3 drive respectively fasten action bars 7 with under to fasten action bars 8 extrapolated, thereby finish the release of upper and lower keeper, upper and lower keeper and door leaf are fixed, finish the process of closing the door.
The effect that the utility model extension spring 6 cooperates with reset arm 4 is to dial plate 1 after stirring up and down in order to make, and under the effect of extension spring 6, dials plate 1 and can rest on panel slotted hole 5.2 edges by nature.
The content that is not described in detail in this manual belongs to this area professional and technical personnel's known prior art.
