Connecting plate for traction section bar of automatic telescopic type curtain

Abstract

The invention discloses a connecting plate for the traction section bar of an automatic telescopic type curtain. The connecting plate is arranged between two traction section bars, and comprises a first connecting piece of which one end is connected with one of the traction section bars, a first guiding limiting piece connected with the other end of the first connecting piece, a second connecting piece of which one end is connected with the other section bar, and a second guiding limiting piece connected with the other end of the second connecting piece, wherein a first baffle is arranged at each of the two end parts of the first guiding limiting piece; a first steel pipe is arranged between the two first baffles; a second baffle is arranged at each of the end parts of the second guiding limiting piece; a second steel pipe is arranged between the two second baffles; the two end parts of a sliding plate are clamped onto the first steel pipe and the second steel pipe respectively; the first steel pipe and the second steel pipe can slide in long grooves freely. The traction section bar connecting plate is simple in structure, convenient to mount and maintain, enables greenhouse curtain traction section bars to run normally even when the vertical column of greenhouse is wider than the truss of the greenhouse, and avoids the problem that the curtain is incapable of completely blocking light.

Description

Technical field [0001] The invention relates to a connecting plate, in particular to an automatic telescopic curtain traction profile connecting plate. Background technique [0002] The good growth in the greenhouse depends to a large extent on the appropriate amount of light transmission to the plants in order to facilitate photosynthesis and promote the growth of plants; some plants need to be shaded when they do not need long-term light transmission; in recent years, Generally, automatic retractable curtains are used to shade the light. The automatic retractable curtains generally move horizontally inside the greenhouse to shade the light, and are used to cover the space above the plants. [0003] When the existing automatic telescopic curtain is opened or closed, it is generally realized by the traction profile provided at the front end of the curtain and the power device connected with the traction profile. The traction profile generally has a horizontal strip structure; The ...

Problems solved by technology

[0003] When the existing automatic retractable curtain is opened or closed, it is generally realized by the traction profile arranged at the front end of the curtain and the power device connected with the traction profile. The traction profile is generally a horizontal strip structure; due to some The width of the greenhouse column in the greenhouse is greater than the width of the greenhouse truss. When the curtain is closed, the traction profile will first touch the greenhouse column. At this time, the curtain cannot be completely closed, which will affect the shading effect of the curtain and damage the growth of plants. surroundings
