Description
Technical field
The utility model belongs to door lock technical field, particularly relates to the anti-external opening structure of a kind of internal lock.
Background technique
Security door usually has opal at present, and need not be opened the door by opal can observe outdoor situations.Occur one now
Kind door opening method pries through the opal of outdoor situations by destroying outdoors, then the stock of a special designing is stretched on door
Enter interior, lower pressure gate Internal handle is directly unlocked, and has very big hidden danger in safety.
Utility model content
The utility model proposes the anti-external opening structure of a kind of internal lock is to provide, solve in the prior art due to setting
There is opal, leads to the defect that can be unlocked by opal.
The technical solution of the utility model is achieved in that
The anti-external opening structure of a kind of internal lock, including shell and handle, the handle connect shaft, the shaft
One end is fixedly connected with handle, and other end connection rotating block is connect with shell, and rebound component is provided on rotating block, further includes bullet
Property bolt, be provided with the first card hole on the rotating block, be provided with the second card hole on the shell, the resilient pin passes through the
Two card holes and the first card hole are connected on handle.
Under normality, resilient pin is plugged in the first card hole and the second card hole, therefore, it is impossible to which swing handle, only presses
Resilient pin is detached from the first card hole and the second card hole could swing handle by resilient pin.
Preferably, the resilient pin is set on the bottom surface of the shaft.
Preferably, slide slot is provided on the bottom surface of the shaft, the resilient pin is connected to described slide by spring
In slot.
Preferably, the resilient pin is L shape.
Preferably, it is arranged fluted on the bottom surface of the handle, the end of resilient pin is arranged in the groove, convenient for pressing
Press the resilient pin.
In conclusion utility model has the advantages that
A kind of internal lock of the utility model anti-external opening structure uses resilient pin in the present apparatus, sets on rotating block
It is equipped with the first card hole, the second card hole is provided on shell, resilient pin passes through the second card hole and the first card hole is connected on handle,
When only resilient pin being extracted, rotating block is just able to rotate, and otherwise can not be rotated, that is, be fail to open door lock.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the anti-external opening structure of a kind of internal lock of the utility model；
Fig. 2 is the structural schematic diagram of resilient pin connecting hole in Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts

As shown in Figs. 1-2, the anti-external opening structure of a kind of internal lock, including shell 1 and handle 2, the handle 2 connect
One end of shaft 3, the shaft 3 is fixedly connected with handle 2, and other end connection rotating block (not shown) is connect with shell, is rotated
Rebound component is provided on block, rotating block and rebound component are existing technical solution herein, are repeated no more again；
Further include resilient pin 4, the first card hole 5 is provided on the rotating block, is provided with the second card hole on the shell
6, the resilient pin passes through the second card hole 6 and the first card hole 5 is connected on handle.Under normality, resilient pin is plugged in first
In card hole and the second card hole, therefore, it is impossible to swing handle, only pressing resilient pin, by resilient pin be detached from the first card hole and
Second card hole ability swing handle, the resilient pin 4 are set on the bottom surface of the shaft, are provided on the bottom surface of the shaft
Slide slot, the resilient pin are connected in the slide slot by spring, and the resilient pin is L shape, the bottom of the handle
It is arranged fluted on face, the end 7 of resilient pin is arranged in the groove, connects specifically, the end of resilient pin passes through spring
It is connected to and has a try in groove, one end of spring and the end of resilient pin connect, in other end connecting groove, convenient for pressing the bullet
Property bolt.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
