Description
Technical field
This utility model relates to a kind of electric-powered shutter, particularly relates to the lower limit of a kind of electric shutter
Device.
Background technology
Shutter is i.e. provided with the window of BAIYE.Generally BAIYE is arranged in double glazing, it is to avoid it is by blast
Impact, and be difficult to make dirty.Shutter in the market is divided into manually, electrically two kinds, and electric-powered shutter has
Having quick and easy feature, along with the raising of people's living standard, its use is more and more extensive.But,
Electric-powered shutter on existing market, its descending stopping means many employings contact limit switch, fault rate is relatively
Often there is the phenomenon not flicked in the contact of height, especially limit switch, and then breaks down, and causes hundred
Leaf cannot move downward again, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that the lower limit of a kind of electric shutter
Device, easily occurs not flicking phenomenon solving the limit switch contact of the descending stopping means of existing electric-powered shutter,
Cause the problem that BAIYE cannot move downward again.
The purpose of this utility model is to be achieved through the following technical solutions:
The lower caging device of a kind of electric shutter, opens including shell and the lower limit that is arranged in shell
Closing, be rotatably connected to power transmission shaft in described shell, the outer peripheral face of described power transmission shaft is provided with the first driving cog,
Being fixedly connected with fixing bar in described shell, the middle of described fixing bar is provided with screw thread, and threaded
Nut, the outer peripheral face of described nut is had to be provided with the second driving cog being meshed with the first driving cog, fixing bar
Two ends be optical axis, and on the optical axis of fixing bar one end, be rotationally connected triggering block, described triggering block be provided with
For pressing the trigger arm of lower position switch contact, the described nut end face adjacent to triggering block one end circumferentially side
To being evenly equipped with multiple drive link for driving triggering block to rotate, described triggering block is provided with and drive link phase
The drive block coordinated.
As a kind of preferred version of the present utility model, the optical axis of described fixing bar one end is provided with for preventing
Only triggering block buckle in axial sliding.
As a kind of preferred version of the present utility model, described drive block is 2, is symmetrically arranged in triggering
On the end face of block.
The beneficial effects of the utility model are, the lower caging device of described a kind of electric shutter can pass through
Nut drives triggering block to rotate, and then the trigger arm of triggering block is departed from the trigger point of lower position switch,
Solve the problem that the limit switch contact of conventional electric blind lower caging device is difficult to flick, simple in construction,
It is easily achieved.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
It is understood that embodiment described herein is used only for explaining this utility model, rather than to this practicality
Novel restriction.
Refer to shown in Fig. 1, Fig. 1 is the lower caging device of this utility model a kind of electric shutter
Internal structure schematic diagram.
In the present embodiment, the lower caging device of a kind of electric shutter, including shell and outside being arranged at
Lower position switch 1 in shell, is rotatably connected to power transmission shaft 2, the outer peripheral face of described power transmission shaft 2 in described shell
It is provided with the first driving cog 3, in described shell, is fixedly connected with fixing bar 4, the middle of described fixing bar 4
Being provided with screw thread, and threaded have nut, the outer peripheral face of described nut is provided with and the first driving cog 3 phase
Second driving cog 5 of engagement, the two ends of fixing bar 4 are optical axis, and the company of rotation on the optical axis of fixing bar 4 left end
It is connected to triggering block 6, and is provided with for preventing triggering block 6 buckle 7 in axial sliding, in described triggering block 6
Being provided with the trigger arm 8 for pressing lower position switch contact, the end face of described nut left end is the most equal
It is furnished with multiple drive link 9 for driving triggering block 6 to rotate, described triggering block 6 is provided with and drive link 9
The drive block 10 matched, described drive block 10 is 2, is symmetrically arranged on the end face of triggering block 6.
Time descending, driven by motor power transmission shaft 2 rotates, and power transmission shaft 2 is by the first driving cog 3 and nut
Second driving cog 5 engages, and then drives nut rotation, does straight line fortune along fixing bar 4 while nut rotation
Dynamic, when moving at triggering block 6, the drive link 9 of nut coordinates the drive block 10 in triggering block 6 to realize
The rotary motion of triggering block 6, and then drive trigger arm 8 to rotate, trigger arm 8 rotates and presses lower limit to be opened
The contact closed, and then downward movement is stopped；When up, triggering block 6 rotates round about, meeting
Drive trigger arm 8 to flick at lower position switch immediately, and then guarantee can realize the most descending.
The lower caging device of above-mentioned a kind of electric shutter can carry out adjusting nut by the fixing bar 4 of rotation and exist
Position on fixing bar 4, thus adjust the position of lower limit.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by upper
Stating embodiment to limit, on the premise of without departing from this utility model spirit and scope, this utility model also has each
Plant change and change, in the range of these changes and change both fall within claimed this utility model.This practicality
Novel claimed scope is defined by appending claims and equivalent thereof.
