Description
Technical field
The utility model relates to the technical field of lock, is specifically related to a kind of safeties of safety door latch.
Background technology
Door lock is a kind of device that door-plate can be pinned, existing door lock generally comprises lock body, dead bolt, tongue driving device, lever handle device and safeties, lock body comprises the lock body housing be arranged in a body, and tongue driving device is positioned at the external dead bolt of lock body shell by being installed in lock body housing to be connected to, and lever handle device to be located at lock body shell external and be connected to tongue driving device, the running of bolt device is driven by lever handle device, to make tongue driving device drive the reciprocating motion of dead bolt, safer when can make by driving safeties to close.But the usual structure of safeties of existing safety door latch is comparatively complicated, and not only manufacturing cost is high, assembly technology is complicated, and easily damages in use procedure, and application life is short.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is more simple, manufacturing cost is lower, it is more convenient to assemble, and the safeties of the safety door latch of not fragile, long service life.
In order to solve the problem existing for background technology, the utility model have employed following technical scheme: a kind of safeties of safety door latch, comprise fixed base plate, safety plate, insurance drive block, insurance driving chip, double end back-moving spring, spring fitting post and safety plate interlock post, described insurance drive block is by drive block body and compress arm and form, described insurance drive block is installed on fixed base plate by drive block body, described safety plate to fit on fixed base plate and near below insurance drive block, described spring fitting post is fixed on fixed base plate by the position on the right side of safety plate, described safety plate interlock post is fixed on safety plate, the two ends of described double end back-moving spring are sheathed on spring fitting post and safety plate joint pin respectively, described drive block body is provided with and the through hole insuring driving chip cross section adaptation, described insurance driving chip is through the through hole both sides of drive block body.
Pass through technique scheme, the safeties structure of this safety door latch is more simple, manufacturing cost is lower, assemble also more convenient, and it is not fragile, longer service life, when using external force to rotate insurance driving chip, insurance driving chip just can drive insurance drive block to rotate, wherein when insuring drive block and rotating, it compresses arm and is moved down by promotion safety plate, thus play the effect of insuring, and when insuring drive block and rotating back into original position, double end back-moving spring moves on drive safety plate, safety plate is set back, thus insurance is opened, operation is very easy.
Further setting of the present utility model: described safety plate is provided with breach near the position of insurance drive block, described compresses the left and right sides that arm and drive block body contact at described breach respectively.
By technique scheme, thus the position relationship of safety plate and insurance drive block can be made more reasonable, and then insurance drive block can be made better to drive moving down of safety plate, during to avoid insuring, produce the phenomenon of clamping stagnation.
Further setting of the present utility model: the keep left position of side of described safety plate is provided with longitudinal elongated slot, described fixed base plate is provided with one through the limited post of longitudinal elongated slot.
By technique scheme, the setting of limited post and longitudinal elongated slot can be good at path when correcting safety plate moves up and down, and produces the phenomenon of off normal when moving up and down to avoid safety plate.
Further setting of the present utility model: the top compressing arm described fixed base plate being positioned at insurance drive block is provided with spacing preiection, and described spacing preiection is inconsistent with the upper surface compressing arm.
By technique scheme, the setting of spacing preiection can play effect that is fixing and restriction insurance drive block position, to prevent from producing biased phenomenon during insurance drive block return, and keeps position relationship accurately.
The beneficial effects of the utility model are: the safeties structure of safety door latch of the present utility model is more simple, manufacturing cost is lower, assembling is also more convenient, and not fragile, longer service life, that insures is simple to operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the safeties of a kind of safety door latch of the utility model.
Detailed description of the invention
In order to make content of the present utility model more clear, below in conjunction with embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the safeties of a kind of safety door latch of the utility model embodiment, comprise fixed base plate 1, safety plate 2, insurance drive block 3, insurance driving chip 4, double end back-moving spring 5, spring fitting post 6 and safety plate interlock post 7, wherein, insurance drive block 3 is by drive block body 31 and compress arm 32 and form, insurance drive block 3 is installed on fixed base plate 1 by drive block body 31, further, safety plate 2 to be fitted on fixed base plate 1 and near below insurance drive block 3, spring fitting post 6 is fixed on fixed base plate 1 by the position on the right side of safety plate 2, safety plate interlock post 7 is fixed on safety plate 2, further, the two ends of double end back-moving spring 5 are sheathed on respectively on spring fitting post 6 and safety plate joint pin 7, further, drive block body 31 is provided with and the through hole 311 insuring driving chip 3 cross section adaptation, insurance driving chip 3 is through through hole 311 both sides of drive block body 31.The safeties structure of this safety door latch is more simple, manufacturing cost is lower, assemble also more convenient, and it is not fragile, longer service life, when using external force to rotate insurance driving chip 4, insurance driving chip 4 just can drive insurance drive block 3 to rotate, wherein when insuring drive block 3 and rotating, it compresses arm 32 and is moved down by promotion safety plate 2, thus play the effect of insuring, and when insuring drive block 3 and rotating back into original position, double end back-moving spring 5 moves on drive safety plate 2, safety plate 2 is set back, thus insurance is opened, operation is played very convenient.
