Abstract
The invention discloses a safe U-shaped locking point for a casement. The safe U-shaped locking point comprises a U-shaped ring, a base and a limiting block. The technical scheme has the following key points: the casement is closed, a casement sensor can conveniently feed an annular buckle fixed on a transmission bar into a hollow cavity of the safe U-shaped locking point of the casement arranged on a window frame under a function of the torsion of a handle of the casement, and the annular buckle is safely covered, so that illegal persons cannot approach the annular buckle by using a common tool on the outer side of the window and cannot prize or destroy the safe U-shaped locking point of the casement; moreover, the annular buckle cannot be moved, the handle of the casement cannot be rotated and the casement cannot be opened, and therefore, the illegal persons cannot enter houses of residents and the properties of the residents can be protected. The handle of the casement is twisted oppositely, and the casement sensor can drive the annular buckle on the transmission bar for being withdrawn from the inside of the hollow cavity formed by the U-shaped ring and the base, so that the casement can be opened normally. The safe U-shaped locking point for the casement is suitable for all new and old customers who use plastic steel windows and broken bridge aluminum alloy windows.
Description
Technical field the present invention relates to a kind of lock point of sash safety, particularly a kind of U-shape lock of sash safety point.
Background technology is current; the lock point that known plastic-steel window, broken-bridge aluminum alloy window sash adopt; be the lock point that some security performances are low, these lock points do not have protective effect to fixing latch closure above the transmission bar of sash driver, close after sash; illegal people is in window outside; use common tool to be easy to prize latch closure fixing above transmission bar, or the bad lock point being fixed on window frame of sled, sash just can be opened; just can enter resident family's family, the property of theft resident family.
Summary of the invention the object of the invention is to provide a kind of improved can improve plastic-steel window, the safety of broken-bridge aluminum alloy window sash, the safe U-shape lock point of sash firmly.
The safe U-shape lock point of sash of the present invention is achieved by the following technical solution: the safe U-shape lock point of sash is made up of U-shaped circle, base and limited block.Described U-shaped circle both sides wall thickness difference, the openend of heavy wall one side has the inclined-plane at 30 ° of angles, this inclined-plane can make fixing latch closure above the transmission bar of sash driver, under the effect of sash handle torsion, can pass in and out easily the cavity being formed by U-shaped circle and base, described base and U-shaped circle connect as one, on base, there are two 1 outside counter sinks, described limited block and base connect as one, lower than base, can limit the safe U-shape lock point of sash and move forward and backward.When passing outwards through two counter sinks on base from rolling screw, safe sash U-shape lock point can be fixed on the window frame of window firmly.Close sash, under the effect of sash handle torsion, the transmission bar of driver can drive latch closure; enter in the cavity being formed by U-shaped circle and base; latch closure is shrouded safely, and illegal people, in window outside, uses common tool cannot approach latch closure; cannot prize or destroy the safe U-shape lock point of sash; latch closure can not be moved, and sash handle can not be rotated, and sash can not be opened; illegal people just cannot enter into resident family's family, and the property of man of resident family has just obtained protection.Turn-back sash handle, the transmission bar of driver can drive latch closure, in the cavity being made up of U-shaped circle and base, exits, and sash can normally be opened.The safe U-shape lock point of sash of the present invention is applicable to the old and new users of all use plastic-steel windows and broken-bridge aluminum alloy window.
Owing to adopting technique scheme, the safe U-shape lock point of sash provided by the invention has following beneficial effect:
1, the safe U-shape lock point of sash, making is easily, installation is easy, cheap, security performance is high, practical, can not affect the attractive in appearance and application life of window frame;
2, the safe U-shape lock point of sash, can not produce any impact to the original function of the driver of sash and window frame.
Brief description of the drawings concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Oblique view when Fig. 1 is the safe U-shape lock point horizontal positioned of sash;
Fig. 2 is that the safe U-shape lock point of sash is installed on window frame, oblique view when fixing latch closure enters in the cavity being made up of U-shaped circle and base above the transmission bar of sash driver.
Detailed description of the invention, below in conjunction with the drawings and specific embodiments, is described in further detail the present invention.
In figure, described U-shaped circle 1, base 2 and limited block 3 threes connect as one, the wall thickness difference of described U-shaped circle 1 both sides, the openend of heavy wall one side has the inclined-plane 4 at 30 ° of angles, this inclined-plane 4 can make latch closure 5 fixing above the transmission bar of sash driver, under the effect of sash handle torsion, can pass in and out easily the cavity 6 being formed by U-shaped circle 1 and base 2.
Above described base 2, there are two outside counter sinks 7.
Described limited block 3 is lower than base 2.
When from rolling screw 8 through two counter sinks 7 on base, safe sash U-shape lock point can be fixed on the window frame of window.
