Electric window opening machine capable of adjusting stroke

Abstract

The invention relates to an electric window opening machine capable of adjusting stroke. The electric window opening machine capable of adjusting the stroke includes an upper shell, a lower shell, anda motor, a reducing mechanism, and a wheel chain which are mounted in the lower shell, and further includes a locating pin, wherein a chain is placed in the lower shell through a chain guide rail, arail groove is formed below the chain by the chain guide rail, locating holes penetrating through the two side walls of one chain plate are formed in the chain plate of two or more chain links on thechain, the locating pin is inserted into and fixed into the locating hole of one chain link, and the end, near the lower shell, of the locating pin extends from the locating hole; and a limiting switch provided with a contact is mounted below the chain wheel by the chain guide wheel, the limiting switch is electrically connected with a power switch of the motor through a circuit board, an elasticclamping buckle located on the contact is further fixed below the chain wheel by the chain guide wheel, and when the locating pin passes above the elastic clamping buckle, the elastic clamping bucklecan be extended by the end, extending out of the locating holes, of the locating pin to extrude and deform and make contact with the contact to trigger the limiting switch. According to the electric window opening machine capable of adjusting the stroke, multiple-stroke gear adjusting of the window opening machine is realized, different using requirements are met, and company producing and inventory reducing are advantageous.

Problems solved by technology

[0002] The chain-type window opening machine on the existing market includes a motor assembly connected to a chain assembly, the motor assembly and the chain assembly are arranged in the housing, the chain assembly is a sprocket and a chain is arranged on the sprocket, and the connecting piece is connected to the chain assembly and arranged on the window Above, the motor assembly is connected to the housing. The motor assembly includes a reduction mechanism housing, a motor, a motor mounting seat, a reduction mechanism and a control panel. The chain type window opener is generally a product with a fixed stroke. Once the assembly is completed, the stroke cannot be adjusted. If you want to change the itinerary, you have to disassemble the machine and reconfigure the chain with a suitable length. The whole process is difficult and time-consuming; with the increase of window opener projects, the demand for the itinerary in the market is becoming more and more diverse, but manufacturers cannot realize it. Large stock of every size

[0003] At present, there are also products on the market that adjust the stroke through micro switches or Hall sensors, but the general stroke length is adjusted in a fixed number of steps, and it is impossible to achieve subtle personalized adjustments.
