Description
Technical field
The utility model relates to a kind of security door latch, the stealthy automatic pinning particularly a kind of antitheft double door used.
Background technology
At present, the office building that entering house door is larger and house are are generally installed and used and are had both antitheft and antitheft double door that is security performance, theftproof lock is arranged on the main door of antitheft double door, secondary door installs upper and lower cotter joint, when usually passing in and out, secondary door is generally maintained static by upper and lower cotter joint and doorframe, opening upper and lower cotter joint when moving the large part such as furniture or electrical equipment more secondary door to be opened, easy access at ordinary times can be ensured, large furniture can be allowed again to move into easily.But the upper and lower cotter joint that present secondary door uses in use exists lower problem: one is that upper and lower cotter joint needs manual unlocking and hand-reset, operation uses very inconvenient, and manual opening and closing latch easily causes parts damages frequently, reduces the application life of latch.Two is because upper and lower cotter joint is arranged on the upper and lower side of secondary door, causes old man and child to be not easy maybe cannot open due to reason operations such as trick inconvenience, height or strength.For this reason, many manufacturers and knowledgeable people have carried out R and D, but not yet have rational product to emerge so far.
Summary of the invention
For overcoming the deficiency existing for existing security door latch, the purpose of this utility model is to provide that a kind of simple and reasonable, flexible operation, use are light, novel structure, elegant in appearance, automatic stealthy automatic pinning of closing the door.
The utility model solves the technical scheme that its technical problem adopts, it comprises upper and lower cotter joint mechanism, operating mechanism and connector, described bolt mechanism comprises plug housing, dead bolt, back-moving spring, dead bolt conduit, dead bolt is fixedly connected with dead bolt conduit, dead bolt and dead bolt conduit are movably arranged on plug housing, dead bolt stretches out from plug housing, and dead bolt conduit stretches out from the bottom of plug housing, and back-moving spring is set on the dead bolt conduit between dead bolt and plug housing.
Further scheme of the present utility model, described operating mechanism comprises interior handle holder, interior handle rotating shaft, lever, interior handle rotating shaft to be arranged on rotationally on interior handle holder and to stretch out from secondary door face board, lever symmetry is fixed in interior handle rotating shaft, and the two ends of lever are connected with the dead bolt of upper and lower cotter joint mechanism respectively by connector.
Further scheme of the present utility model, described dead bolt is oblique dead bolt, and connector is wire rope.
Further scheme of the present utility model, described interior handle holder is provided with the left and right spacer pin coordinated with interior handle rotating shaft.
After adopting said structure, have the following advantages compared with the prior art and effect: one is because back-moving spring is set on the dead bolt conduit between dead bolt and plug housing, and dead bolt produces bounce under action of reset spring makes dead bolt automatically reset.Two is because lever symmetry is fixed in interior handle rotating shaft, the two ends of lever are connected with the dead bolt of upper and lower cotter joint mechanism respectively by connector, when needs open auxiliary door, interior handle in rotating in handle rotating shaft, interior handle rotating shaft pulls upper and lower dead bolt to bounce back by lever and connector, can open upper and lower dead bolt simultaneously; When closing secondary door, pull the interior handle in interior handle rotating shaft, upper and lower dead bolt is automatic retracted under dead bolt inclined-plane coordinates, the automatic spring again when upper and lower dead bolt aims at the pin hole on doorframe, flexibly simple to operate, easy to use.Three is that outside be can't see because upper and lower cotter joint mechanism, operating mechanism and connector are installed and be hidden in secondary door, novel structure, elegant in appearance.

Detailed description of the invention
Shown in Fig. 1 and Fig. 2, for the specific embodiments of a kind of stealthy automatic pinning of the utility model, it comprises the upper and lower cotter joint mechanism 1 be arranged on secondary door, operating mechanism 3 and connector 2, described bolt mechanism 1 comprises plug housing 12, dead bolt 11, back-moving spring 13, dead bolt conduit 14, plug housing 12 is fixed on secondary door, dead bolt 11 is fixedly connected with dead bolt conduit 14, dead bolt 11 and dead bolt conduit 14 are movably arranged on plug housing 12, dead bolt 11 to stretch out and corresponding with the pin hole of doorframe from plug housing 12 and secondary door, dead bolt conduit 14 stretches out from the bottom of plug housing 12, back-moving spring 13 is set on the dead bolt conduit 14 between dead bolt 11 and plug housing 12.Described operating mechanism 3 comprises interior handle holder 31, interior handle rotating shaft 34, lever 33, interior handle holder 31 is fixed on secondary door, interior handle rotating shaft 34 to be arranged on rotationally on interior handle holder 31 and to stretch out from secondary door face board, lever 33 symmetry is fixed in interior handle rotating shaft 34, and the two ends of lever 33 are connected with the dead bolt 11 of upper and lower cotter joint mechanism 1 respectively by connector 2.
Conveniently dead bolt 11 automatic retracted, described dead bolt 11 is oblique dead bolt, and for the ease of installing, connector 2 is wire rope.In order to control lever 33 rotational angle, described interior handle holder 31 is provided with the left and right spacer pin 32 coordinated with interior handle rotating shaft 34.
During the utility model open auxiliary door, rotate the interior handle that is fixed in interior handle rotating shaft 34, interior handle rotating shaft 34 is rotated thereupon and is pulled the upper and lower dead bolt 11 upper and lower dead bolt 11 that bounces back to depart from and the coordinating of doorframe pin hole by lever 33 and wire rope, gets final product open auxiliary door.When closing secondary door, pull the interior handle be fixed in interior handle rotating shaft 34, automatic retracted after upper and lower dead bolt 11 overcomes the spring force of back-moving spring 13 under dead bolt inclined-plane coordinates, when upper and lower dead bolt 11 aims at the pin hole on doorframe, upper and lower dead bolt 11 again automatic spring inserts in the pin hole of doorframe, thus realization is closed the door automatic locking, flexible operation, easy to use.
The above; just specific embodiment of the utility model, not makes any pro forma restriction to the utility model, is not departing from the technical solution of the utility model basis; done simple modification, equivalent variations or modification, all fall into protection domain of the present utility model.
