Problems solved by technology
[0004] However, when the above-mentioned slider slides on the track, the moving part easily collides with the side wall at the opening of the track to generate noise, and also easily collides between the slider and the slider to generate noise, which causes the electric curtain to run. The noise is large, which affects the user's experience effect; a wheel body is formed on the same diameter as the moving part of the slider, and the wheel body is rollingly matched with the guide rail of the curtain body movement track, so when installing, it is necessary to pay attention to the direction of the slider The body can only be pressed in after being aligned with the two guide rails of the curtain body movement track, which increases the difficulty of installation and reduces the production efficiency; due to the rolling friction between the wheel body of the slider and the guide rail of the track, when the slider is loaded When the material of the curtain body is light, the noise generated by the friction between the slider and the guide rail of the track is relatively large
[0005] Another example is a suspension ring for curtains with the patent application number CN200920165871.3, which includes an upper pulley body and a lower hanging ring body, and the upper pulley body is slidably matched with the curtain guide rail. Slidingly fit with the curtain guide rail, the bottom surface of the pulley body is in full contact with the curtain guide rail, and the noise generated by the friction is relatively large, and especially when the curtain is pulled by hand, the tension on the ring is uneven, causing the ring to deviate toward the side facing the person in the guide rail , causing the side of the pulley body to rub against the guide rail or the belt in the guide rail, which not only produces noise, but also damages the rings, guide rail and belt after long-term operation, affecting the service life of the entire curtain

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] see figure 1 , a curtain track, comprising a track 100 and a suspension wheel 1, the bottom surface of the track 100 is provided with an opening 101 extending along the length direction, and side walls 102 are formed on opposite sides of the opening 101. The suspension wheel 1 passes through the opening 101 on the bottom surface of the track 100 , and partially enters the track 100 , and a plurality of suspension wheels 1 are arranged at intervals in the track 100 .
[0023] see figure 2 and image 3 The hanging wheel 1 includes a hanging wheel main body 11 , a lifting ring 12 arranged at the bottom of the hanging wheel main body 11 , and a baffle 13 arranged at the top of the hanging wheel main body 11 . The hanging wheel main body 11 is used to connect with the track 100, while the hanging ring 12 is used to connect with the curta...

The invention discloses a hanging wheel. The hanging wheel comprises a hanging wheel body and a hanging ring arranged at the bottom of the hanging wheel body. A baffle is arranged on the upper portion of the hanging wheel body. A stop part is formed on the hanging wheel body. The hanging wheel is characterized in that a first sunken part which is sunken inwards in the radial direction is formed in the upper portion of the hanging wheel body; an annular flexible rubber part is arranged on the periphery of the first sunken part; the stop part is located below the first sunken part; a rubber ring is arranged on the periphery of the baffle; the periphery of the rubber ring protrudes out of the periphery of the baffle; the bottom face of the baffle is in a bevel shape which inclines from the periphery towards the center of the hanging wheel body gradually. The invention further discloses a curtain track comprising the hanging wheel. The flexible rubber part is arranged in the position where the hanging wheel makes contact with the sidewall of a track opening, and noise generated by collision between the hanging wheel and the track can be reduced; the rubber ring protruding out of the baffle is arranged on the part, located in the track, of the hanging wheel, and accordingly noise generated by collision between hanging wheels can be reduced.
Description
technical field [0001] The invention relates to a mechanical transmission part, in particular to a hanging wheel sliding in a curtain track, and a curtain track using the hanging wheel. Background technique [0002] In the existing motor-driven curtain mechanism on the market, the rolling suspension wheel is usually used as the sliding part on the track, the upper end of the curtain is fixed with the suspension ring of the suspension wheel, and the end point of the curtain is fixed on the track block through the suspension wheel. The trolley is driven by a motor and can slide on the track, and the other parts of the curtain directly slide on the track through the suspension wheel. [0003] For example, a curtain slider whose patent application number is CN200610067471.X, the moving part at the upper end of the slider main body is pressed into the guide rails of the moving track of the curtain body, the main body of the slider rotates horizontally with the longitudinal axis a...
