Technical Field

The invention relates to an electric window opener, in particular to a rigid chain electric window opener.

Background

With the development of modern buildings, the large size, the large weight and the large opening stroke of the window body are often the requirements of customers, the general chain type electric window opener in the prior art cannot adapt to the requirements of larger stroke and larger weight, and the technical scheme that the patent CN103276997B, namely a self-meshing tiger-tooth heavy chain type electric window opener, relies on two tiger-tooth-shaped chains to be meshed and buckled into a rigid integrated chain to increase the thrust and the stroke cannot be reliably popularized due to the defects that the processing requirement is high, the production cost is high, the meshing of the two tiger-tooth-shaped chains is easy to be blocked and the like.

Disclosure of Invention

In view of the above problems, the present invention provides a rigid chain electric window opener, which can provide a larger stroke and push force to open a larger window, and can also be used as an electric push rod.

The purpose of the invention is realized by the following technical scheme.

The utility model provides an electronic ware of windowing of rigid chain which characterized in that: the device comprises a shell, a speed reducing motor, a left anti-bending chain, a track, a right anti-bending chain, a left chain wheel, a guide block, a driving head and a right chain wheel; one side edge of the anti-bending chain sheet is straight, one end face is convex, and the other end face is concave; the end faces of the connected chain sheets of each chain sheet are matched and abutted, and the chain can only rotate towards the reverse direction of the straight edge; the left and right chain wheels drive the left and right anti-bending chains to move along the track with the inclination angle, when the anti-bending chains are meshed with the chain wheels, the left and right chain pieces are separated and do not interfere with each other, when the anti-bending chains are close to the guide blocks, the straight edges of the left and right anti-bending chain pieces are abutted, the anti-bending chains are constrained and closed by the guide blocks and are fixed on the driving head, and a rigid chain is formed and extends out of the shell of the electric push rod.

The anti-bending chain is characterized in that an inner chain link is composed of inner chain pieces, sleeves and rollers, outer chain pieces are arranged on the outer side of each inner chain link, and the inner chain pieces are fixed through pin shafts to form a chain.

The track is characterized in that the track is divided into a left guide rail end face and a right guide rail end face, the guide rail end faces support rollers of the chains to move on the inner sides of the inner chain pieces, and the track, which supports the left and right anti-bending chains to move from the horizontal direction to the vertical direction, of the left and right guide rail end faces is an inclined angle.

The speed reducing motor drives the left chain wheel to synchronously drive the right chain wheel through the gear, and the left chain wheel and the right chain wheel are synchronously meshed to drive the left anti-bending chain and the right anti-bending chain to move.

The left chain wheel is driven by a left speed reducing motor, the right chain wheel is driven by a right speed reducing motor, and the double speed reducing motors control the motors to be synchronous through a synchronous controller.

Compared with the existing chain type window opener, the chain type window opener can increase the thrust, can open a window with large stroke and heavy weight, and meets the requirements of people on the electric window opener; compared with CN103276997B A self-meshing tiger tooth heavy chain type electric window opener, the technical scheme has the advantages of low processing requirement, low production cost, the generated thrust and stroke are the same, and the performance is more reliable.
