Background technology
Microswitch is one kind of travel switch, and warning function is realized using microswitch in smart lock middle groove.It is existing
Some microswitches are divided into big stroke and small stroke, although big travel switch meets range demands when in use, due to
Volume is big, leads to problems such as to occur difficult to install or can not install, while is of high cost；Although small travel switch is easily installed,
But stroke is too small, using in smart lock pick-proof, due to door-plate itself deformation or manufacture when door-plate setting bumps
Lines so that there are fit clearance between microswitch and door-plate, microswitch is to connect signal condition in original state, is caused
False alarm is generated, also or is excessively to coordinate that microswitch is led to problems such as to be damaged by pressure by door-plate with door-plate.
Utility model content
The utility model offer microswitch stroke adjustment structure solves one or more in prior art problem.
Microswitch stroke adjustment structure provided by the utility model, including microswitch, PCB, elastic component, bottom plate, it is micro-
Dynamic switch is fixed on PCB, and PCB is set to bottom plate side, and elastic component is set between PCB and bottom plate, in original state, elastic component quilt
PCB and bottom plate precommpression.
Microswitch stroke adjustment structure provided by the utility model, by increasing adjustable stroke knot to microswitch
Structure can realize automatic adjustment according to the gap between microswitch and door-plate when in use, avoid door-plate and microswitch it
Between gap it is excessive cause, from alarming or the too small damage in gap switch, to be suitable for any Antitampering door lock, use scope is wide, reduction at
This.
In some embodiments, further including positioning column, positioning column is vertically arranged with bottom plate and bottom plate is fixed in one end,
The other end coordinates with PCB, and PCB can be moved on positioning column, and elastic component is sheathed on outside positioning column.
In this way, positioning column can position elastic component, while the movement of PCB is oriented to.
In some embodiments, PCB is equipped with the through-hole that can accommodate positioning column, and positioning column is inserted into through-hole and can be in through-hole
It is mobile；
Further include locking piece, locking piece one end is equipped with limited block, and locking piece one end is connected and fixed across through-hole with positioning column,
Limited block offsets with PCB.
In this way, limited block can prevent PCB from being detached from positioning column.
In some embodiments, elastic component quantity is 2, is respectively symmetrically set to the opposite sides of bottom plate.
In this way, symmetrically arranged elastic component can make PCB, holding is horizontal in the process of moving, ensure microswitch and
The even contact of door-plate.
In some embodiments, elastic component is spring.
In this way, of low cost, restoring force and convergent force are extremely stablized.
Description of the drawings
Fig. 1 is a kind of explosive view of the microswitch stroke adjustment structure of embodiment provided by the utility model；
Fig. 2 is that the structure after a kind of microswitch stroke adjustment structure assembling of embodiment provided by the utility model is shown
It is intended to；
Fig. 3 is a kind of microswitch stroke adjustment structure installation of embodiment provided by the utility model and intelligent locking face
Plate and with the matched structural schematic diagram of door-plate.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings of the specification.
Referring to Fig. 1-3, microswitch stroke adjustment structure, including microswitch 1, PCB 2, elastic component 3, bottom plate 4, fine motion
Switch 1 is fixed on PCB 2, and PCB 2 is set to 4 side of bottom plate, and elastic component 3 is set between PCB 2 and bottom plate 4, in original state, bullet
Property part 3 is by 4 precommpression of PCB 2 and bottom plate.
Microswitch 1 is installed in intelligent lock panel 7 and offsets with door-plate 8 so that door-plate 8 compresses the shrapnel of microswitch 1
11 in cut-off signal state is closed, and when intelligent lock panel 7 is pried open, the shrapnel 11 of microswitch 1 is not by the pressure of door-plate 8
And flick, microswitch 1 connects signal and alarms at this time, has the function that whether monitoring intelligent lock panel 7 is prized.
PCB 2 is for installing microswitch 1 and realizing circuit communication, and in original state, elastic component 3 is compressed such that can
It is automatically adjusted according to fit clearance between microswitch 1 and door-plate 8, when gap between the two is excessive, elastic component 3 can
Push PCB 2 that microswitch 1 is driven to be pushed toward 8 direction of door-plate, when fit clearance between the two is too small, elastic component 3 can be by
Compression ensures between door-plate 8 and microswitch 1 in suitable for matching status.
Microswitch stroke adjustment structure provided by the utility model, by increasing adjustable stroke knot to microswitch 1
Structure can be realized automatic adjustment, door-plate 8 and fine motion avoided to open when in use according to the gap between microswitch 1 and door-plate 8
Close that the gap between 1 is excessive to cause from alarming or the too small damage in gap switch, suitable for any Antitampering door lock, use scope is wide,
Reduce cost.
Further, further include positioning column 5, positioning column 5 is vertically arranged with bottom plate 4 and bottom plate 4 is fixed in one end, another
End coordinates with PCB 2, and PCB 2 can be moved on positioning column 5, and elastic component 3 is sheathed on outside positioning column 5.
Positioning column 5 can position elastic component 3, while can also be oriented to the movement of PCB 2 so that PCB
2 movements are smooth, steady.
