Description

Plug-in for roller shutter bottom beam

Technical Field

The utility model relates to a roll up curtain floorbar accessory, in particular to roll up plug-in components for curtain floorbar.

Background

With the continuous development of building energy conservation, the built-in roller shutter window effectively avoids the problems of cleaning and the like because the roller shutter is built in. The built-in roller shutter window is characterized in that a built-in roller shutter device is packaged between glass, and a driving mechanism drives a roller shutter to lift between the glass. The roller blind bottom beam in the existing built-in roller blind device is one of indispensable accessories. The roller shutter bottom beam is used for fixing the tail end of the roller shutter and balancing weight, and can be in sliding fit with the built-in roller shutter frame body to limit the roller shutter from shaking between the glass. Meanwhile, in order to ensure the light-shielding property of the built-in roller shutter, a groove body is often arranged on a bottom beam of a built-in roller shutter frame, and the bottom beam falls into the groove body along with the falling of the roller shutter to realize better light-shielding property.

However, the existing roller shutter bottom beam is generally formed by assembling the clamping piece and the beam body, and if the assembling strength of the clamping piece and the beam body is not enough, the clamping piece and the beam body are easy to separate along with use. If the assembling strength of the two components is increased, the assembling difficulty may be caused. Meanwhile, when the existing clamping piece is in sliding fit with the sliding groove of the built-in roller shutter frame body, friction and collision are easy to occur, and the problems of unsmooth lifting, noise and the like of the roller shutter are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an assembly is easy, firm in connection, and sliding friction is little for roll up curtain floorbar plug-in components.

Realize the utility model discloses the technical scheme of purpose is: the utility model has a main body; the left side of the main body is provided with a plug-in unit for being inserted into the bottom beam clamping groove, and the left side of the main body is provided with a limiting body for being inserted into the sliding groove to perform sliding limiting; a plugging sheet is arranged on the right side of the plug-in unit on the main body; the blocking piece is provided with a notch through which the roller shutter cloth can pass; the plug-in is provided with latch teeth arranged along the extension direction of the plug-in; the latch includes a plurality of strengthening ribs of arranging along inserting extending direction, all is equipped with the arc piece to keeping away from the direction uplift of plug-in components between the adjacent strengthening rib.

The front side surface and the rear side surface of the limiting body respectively correspond to the inner walls of the two opposite sides of the sliding groove; the front side surface and the rear side surface are arc-shaped surfaces and are symmetrically arranged with each other; the front side face and the rear side face are in line contact with the inner wall of the corresponding sliding groove.

A clamping body is arranged on the upper end face of the plug-in; the clamping body is provided with an embedded groove which is communicated with the notch correspondingly and is used for embedding the roller shutter cloth.

One end of the plug-in unit, which is far away from the plugging sheet, is in a furled shape.

The arc top of the arc piece is positioned at the center between the two corresponding adjacent reinforcing ribs.

The utility model discloses has positive effect: (1) the utility model discloses well latch passes through the arc piece, can let the fastener insert the floorbar draw-in groove more easily in, nevertheless make the fastener be difficult to break away from with the floorbar draw-in groove after warping in the floorbar draw-in groove to it is easy to have realized the assembly, breaks away from difficult effect.

(2) The utility model discloses the arcwall face design of well spacing body for linear contact is when spacing body and spout contact slip, and frictional force is little, and the noise is little, thereby effectively promotes the smooth degree and the use impression of rolling up the curtain lift.

(3) The utility model discloses an embedded groove can carry out effective location protection to the roll of curtain edge that stretches out the notch.

(4) The utility model discloses well arc top position of arc piece lets the latch insert more easily when the assembly, but extracts and do more difficult.
