Description
Technical field
The present invention relates to a kind of electric-powered shutter, more particularly to a kind of lower caging device of electric-powered shutter.
Background technology
Shutter is the window for being provided with blinds.Usual blinds is arranged in double glazing, it is to avoid its by influenced by wind pressure, and
It is difficult to make dirty.Shutter in the market is divided into manually, electrically two kinds, the characteristics of electric-powered shutter has quick and easy, with
The improvement of people's living standards, it is more and more extensive that it, which is used,.However, the electric-powered shutter on existing market, its descending limit
Contact limit switch being used the device of position, fault rate is higher, and the contact of especially limit switch often occurs what is do not flicked more
Phenomenon, and then break down, cause blinds not move downward again, thus, be badly in need of solving.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, a kind of lower caging device of electric-powered shutter is provided, to solve now
The limit switch contact for having the descending stopping means of electric-powered shutter easily occurs not flicking phenomenon, causes blinds not transport downwards again
Dynamic the problem of.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of lower caging device of electric-powered shutter, including shell and the lower position switch that is arranged in shell, it is described outer
Power transmission shaft is rotatably connected in shell, the outer peripheral face of the power transmission shaft, which is provided with the first driving cog, the shell, to be fixedly connected with
Fix bar, the middle of the fix bar is provided with screw thread, and is threaded with nut, the outer peripheral face of the nut be provided with
The second driving cog that first driving cog is meshed, the two ends of fix bar connect to be rotated on optical axis, and the optical axis of fix bar one end
The trigger arm for pressing lower position switch contact is provided with triggering block, the triggering block, the nut is adjacent to triggering block one
The end face at end is along the circumferential direction evenly equipped with multiple drive links for being used to drive triggering block to rotate, the triggering block and is provided with and passes
The drive block that lever is engaged.
As a preferred embodiment of the present invention, it is provided with the optical axis of described fix bar one end for preventing triggering block axle
To the buckle of slip.
As a preferred embodiment of the present invention, described drive block is 2, is symmetrically arranged on the end face of triggering block.
Beneficial effects of the present invention are that a kind of lower caging device of electric-powered shutter can drive triggering block by nut
Rotation, and then the trigger arm of triggering block and the trigger point of lower position switch are departed from, solve conventional electric blind lower limit
The limit switch contact of position device is the problem of be difficult to flick, simple in construction, be easily achieved.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.It may be appreciated
It is that embodiment described herein is used only for explaining the present invention, rather than limitation of the invention.
It refer to shown in Fig. 1, Fig. 1 is a kind of internal structure schematic diagram of the lower caging device of electric-powered shutter of the invention.
In the present embodiment, a kind of lower caging device of electric-powered shutter, including shell and the lower limit that is arranged in shell
Power transmission shaft 2 is rotatably connected in bit switch 1, the shell, the outer peripheral face of the power transmission shaft 2 is provided with the first driving cog 3, described
Fix bar 4 is fixedly connected with shell, the middle of the fix bar 4 is provided with screw thread, and is threaded with nut, the spiral shell
Female outer peripheral face is provided with the second driving cog 5 being meshed with the first driving cog 3, and the two ends of fix bar 4 are optical axis, and fix bar
Triggering block 6 is rotatably connected on the optical axis of 4 left ends, and is provided with for preventing buckle 7 in axial sliding of triggering block 6, it is described to touch
The trigger arm 8 for pressing lower position switch contact is provided with hair block 6, the end face of the nut left end is along the circumferential direction uniform
Have and be provided with the drive block being engaged with drive link 9 in multiple drive links 9 for being used to drive triggering block 6 to rotate, the triggering block 6
10, described drive block 10 is on 2, the end face for being symmetrically arranged in triggering block 6.
When descending, motor drives power transmission shaft 2 to rotate, and power transmission shaft 2 passes through the first driving cog 3 and the second driving cog on nut
5 engagements, and then nut rotation is driven, moved along a straight line while nut rotation along fix bar 4, 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 drives trigger arm 8 to revolve
Turn, trigger arm 8 rotates and presses the contact of lower position switch, and then downward movement is stopped；When up, triggering block 6 to
Opposite direction rotate, trigger arm 8 can be driven to be flicked immediately at lower position switch, so ensure can realize it is descending again.
A kind of lower caging device of above-mentioned electric-powered shutter can by rotating fixing rod 4 come adjusting nut in fix bar 4
Position, so as to adjust the position of lower limit.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and modifications all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
