Abstract
The invention discloses a lower limiting device of a novel electric shutter.The lower limiting device comprises a shell and a lower limiting switch.A transmission shaft is connected in the shell in a rotating mode.First transmission teeth are arranged on the peripheral face of the transmission shaft.A fixing rod is fixedly connected in the shell.A thread is arranged in the middle of the fixing rod.The fixing rod is connected with a nut through the thread.Second transmission teeth meshed with the first transmission teeth are arranged on the peripheral wall of the nut.The two ends of the fixing rod are provided with smooth shafts.The smooth shaft at one end of the fixing rod is connected with a trigger block.The trigger block is provided with a trigger arm used for pressing a contact of the lower limiting switch.A plurality of transmission rods used for driving the trigger block to rotate are evenly distributed in the circumferential direction of the end face of the end, close to the trigger block, of the nut.Transmission blocks matched with the transmission rods are arranged on the trigger block.The trigger block can be driven by the nut to rotate, and therefore the trigger arm of the trigger block can be separated from the contact of the lower limiting switch, and the problem that a contact of a limiting switch of a traditional electric shutter lower limiting device can not be easily bounced off is solved.
Description
Technical field
The present invention relates to a kind of electric-powered shutter, particularly relate to the lower caging device of a kind of electric shutter。
Background technology
Namely shutter is provided with the window of BAIYE。Usual BAIYE is arranged in double glazing, it is to avoid it is subject to influenced by wind pressure, and not easily makes dirty。Shutter in the market is divided into manually, electrically two kinds, and electric-powered shutter has quick and easy feature, and along with the raising of people's living standard, its use is more and more extensive。But, the electric-powered shutter on existing market, its descending stopping means many employings contact limit switch; fault rate is higher, and especially the phenomenon that do not flick often occurs in the contact of limit switch, and then breaks down; cause BAIYE again to move downward, thus, be badly in need of solving。
Summary of the invention
Present invention aims to the problems referred to above, it is provided that the lower caging device of a kind of electric shutter, the limit switch contact to solve the descending stopping means of existing electric-powered shutter easily occurs not flicking phenomenon, causes the problem that BAIYE cannot move downward again。
It is an object of the invention to be achieved through the following technical solutions:
A kind of lower caging device of electric shutter, including shell and be arranged at the lower position switch in shell, it is 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, fixing bar it is fixedly connected with in described shell, the middle of described fixing bar is provided with screw thread, and threaded have nut, the outer peripheral face of described nut is provided with the second driving cog being meshed with the first driving cog, the two ends of fixing bar are optical axis, and the optical axis of fixing bar one end is rotationally connected triggering block, described triggering block is provided with the trigger arm for pressing lower position switch contact, the end face of the contiguous triggering block one end of described nut is along the circumferential direction evenly equipped with multiple drive link for driving triggering block to rotate, described triggering block is provided with the drive block with transmission rod。
As a preferred embodiment of the present invention, the optical axis of described fixing bar one end is provided with for preventing triggering block buckle in axial sliding。
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 is, the lower caging device of described a kind of electric shutter can pass through nut and drive 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 not easily flicks, simple in construction, be easily achieved。

Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention。It is understood that embodiment described herein is used only for explaining the present invention, but not limitation of the invention。
Refer to shown in Fig. 1, Fig. 1 is the internal structure schematic diagram of the lower caging device of a kind of electric shutter of the present invention。
In the present embodiment, a kind of lower caging device of electric shutter, including shell and be arranged at the lower position switch 1 in shell, power transmission shaft 2 it is rotatably connected in described shell, the outer peripheral face of described power transmission shaft 2 is provided with the first driving cog 3, fixing bar 4 it is fixedly connected with in described shell, the middle of described fixing bar 4 is provided with screw thread, and threaded have nut, the outer peripheral face of described nut is provided with the second driving cog 5 being meshed with the first driving cog 3, the two ends of fixing bar 4 are optical axis, and the optical axis of fixing bar 4 left end is rotatably connected to triggering block 6, and it is provided with for preventing triggering block 6 buckle 7 in axial sliding, described triggering block 6 is provided with the trigger arm 8 for pressing lower position switch contact, the end face of described nut left end is along the circumferential direction evenly equipped with multiple drive link 9 for driving triggering block 6 to rotate, described triggering block 6 is provided with the drive block 10 matched with drive link 9, described drive block 10 is 2, it is symmetrically arranged on the end face of triggering block 6。
Time descending, driven by motor power transmission shaft 2 rotates, power transmission shaft 2 is engaged with the second driving cog 5 on nut by the first driving cog 3, and then drive nut rotation, do rectilinear motion along fixing bar 4 while nut rotation, when moving to triggering block 6 place, 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 driving trigger arm 8 to rotate, trigger arm 8 rotates and presses the contact of lower position switch, and then downward movement is stopped；When up, triggering block 6 rotates round about, and trigger arm 8 can be driven to flick from lower position switch immediately, and then guarantee can realize again descending。
The lower caging device of above-mentioned a kind of electric shutter can come adjusting nut position on fixing bar 4 by rotating fixing bar 4, thus adjusting the position of lower limit。
Above example simply elaborates ultimate principle and the characteristic of the present invention; 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 change both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
