Abstract

The utility model relates to a free-stop automatic screen window fit with a profile window, wherein the upper ends of two tracks opposite a notch are provided with a screen box and the lower ends are connected with a bottom frame, the screen box is provided with an automatic rollback mechanism, the upper end of the screen is connected with the automatic rollback mechanism and the lower end is connected with the inner surface of a pull beam, two ends of the pull beam are inserted into the slots of the two tracks, the pull beam is provided with a sliding block capable of sliding on the pull beam, the sliding block is connected with a bolt, the bottoms of the slots of the two tracks are provided with a bolt hole plate. The utility model adopts the location and engagement between the bolts on the sliding block and the bolt hole plate in the slots of the tracks, to realize the free stop of the pull beam and the screen window on a window, to provide a convenient application.

Description

Arbitrarily stop automatic window screen

Technical field

The utility model relate to a kind of on the section bar window matching used screen window, specifically a kind of automatic window screen that arbitrarily stops.

Background technology

Matching used screen window on section bar windows such as aluminium or plastic-steel at present, its primary structure is that two two guide rails that notch is relative are arranged, be connected to the yarn box in the upper end of two guide rails, lower end at two guide rails is connected to underframe, automatic rewinding mechanism is housed in the yarn box, the upper end of gauze and automatic rewinding mechanism join, and the lower end of gauze and the inner face of straining beam join, and the two ends of straining beam extend in the groove of two guide rails.This class screen window is not owing to have positioner at the middle part of guide rail, and in the time of therefore will opening it, the straining beam of gauze can be until the window top just stops action under the pulling of automatic rewinding mechanism; And it will be closed the time, then can only be to move straining beam to underframe could locate, it is closed completely that screen window is realized.But in user's daily use, when needing to transmit some article sometimes by window, if screen window is all opened, then can be owing to the aperture area of sash is excessive, and the possibility that mosquito is flown into increases thereupon.Thereby existing screen door structure, the inconvenience that brings some to use to the user.

The utility model content

The straining beam that the purpose of this utility model just provides a kind of screen window can random positionedly on sash arbitrarily stop automatic window screen, so that the user adjusts the open area of screen window as required arbitrarily, prevents entering of mosquito thus to greatest extent.

The utility model is achieved in that this automatic window screen is a termination yarn box on two relative guide rails of notch, termination underframe under two guide rails, automatic rewinding mechanism is housed in the yarn box, the last termination automatic back-rolling machine structure of gauze, the lower end of gauze and the inner face of straining beam join, and the two ends of straining beam are stretched in the groove of two guide rails, and being provided with on straining beam can be along the slip shifting block of straining beam slip, be connected to latch on the slip shifting block, the base is provided with the latch orifice plate in the groove of two guide rails.

Adopt this structure, when with hand when slip shifting block on the straining beam is stirred on the screen window both sides, latch on the slip shifting block can insert in certain locating hole on the latch orifice plate in two guide-track grooves in both sides, and straining beam is located, thus the location of realization screen window on the window optional position.Clawback slip shifting block, the top of latch can be withdrawed from the locating hole on the latch orifice plate in the guide-track groove, the positioning action of screen window disappears, spur straining beam again or unclamp straining beam this moment, screen window is reorientated by above-mentioned steps in next appropriate location, perhaps retracted and all open by the automatic rewinding mechanism in the yarn box.Thus, realized screen window, thereby greatly facilitated user's actual use the stopping and locating of window any position.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this automatic window screen has the window frame of a rectangle, and the top of window frame is a yarn box 1, and both sides are two relative guide rails 2 of notch, and the base is a underframe.The upper end of yarn box 1 and two guide rails 2 joins, and the lower end of underframe and two guide rails joins.Conventional automatic rewinding mechanism is housed in yarn box 1, the last termination automatic back-rolling machine structure of gauze 6, the inner face of the lower end of gauze 6 and straining beam 4 joins.The two ends of straining beam 4 are stretched in the groove of both sides two guide rails 2.

Being provided with on straining beam 4 can be along the slip shifting block 5 of straining beam slip.Slip shifting block 5 can be arranged on outside, end face or the bottom surface of straining beam 4, can be that fit system and the straining beam 4 by the chase mortise formula is slidingly connected.On slip shifting block 5, be connected to latch 3.Latch 3 both can be positioned at the top (diagramatic way) of straining beam 4, also can be contained in the cavity of straining beam 4, and the top of latch can be stretched out from two end faces of straining beam 4.The latter's good concealment, reasonable structure also are better than the former.The base is provided with the latch orifice plate 7 of strip in the groove of two guide rails 2, to be used for limiting by latch at the arbitrary height of sash the position of straining beam 4 and gauze 6.

Claims

1, a kind ofly can arbitrarily stop automatic window screen, the last termination yarn box (1) of two guide rails (2) that notch is relative, termination underframe under two guide rails, the yarn box is equipped with automatic rewinding mechanism in (1), the last termination automatic back-rolling machine structure of gauze (6), the inner face of the lower end of gauze (6) and straining beam (4) joins, the two ends of straining beam are stretched in the groove of two guide rails (2), it is characterized in that being provided with on straining beam (4) can be along the slip shifting block (5) of straining beam slip, be connected to latch (3) on the slip shifting block, the base is provided with latch orifice plate (7) in the groove of two guide rails.
