Description

Novel anti-falling lock

Technical Field

The utility model relates to a prevent weighing down lock, concretely relates to novel prevent weighing down lock.

Background

The out-opening window does not occupy indoor space after the casement is opened, compares other window types and is favored by the consumer more, but because the out-opening window is opened the back casement and is located outdoors, consequently can receive outdoor air current or gust to disturb and the risk that drops appears, especially in the area that the typhoon is frequent, the risk that the casement falls because of the air current impact is great, in order to improve the safety in utilization of out-opening window, the state regulation requires that the out-opening window must be equipped with safe anti-falling device.

At present, the common anti-falling lock is fixed on a window frame and a window sash through two ends of a rope respectively, an extending state and a twisting state can appear in the process of opening and closing the window sash, and the phenomenon that the rope is clamped by the window sash due to twisting easily appears when the anti-falling lock is in the twisting state, so that a consumer needs to manually adjust the rope, the operation of closing the window by the consumer is increased, and the comfort degree of use is reduced.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to provide a rope is in the anti-falling lock of extending state always.

In order to achieve the above purpose, the utility model provides a following technical scheme: including two mount pads and rope, the both ends of rope set up respectively in two mount pads, and a mount pad sets up on the window frame, and another mount pad sets up on the casement, is provided with the movable block in at least one mount pad and supplies the activity chamber that the movable block slided, and rope one end is stretched into in the mount pad and is fixed with the movable block, and the activity intracavity is provided with the reset spring who extends the direction reset with the movable block to the rope.

By adopting the technical scheme, during installation, the installation seat is fixed on the window frame or the window sash, one end of the rope is fixed along with the installation seat, the other end of the rope is fixed on the corresponding window sash or the window frame, so that when the window is in a closed state, the reset spring is not compressed, and the rope is in an extended state, when the window is opened, the distance between the installation seat and the other end of the rope is increased, the movable block moves towards the direction of the rope, the reset spring is further compressed, finally, the length of the rope outside the installation seat is increased to meet the increase of the distance between the window sash and the window frame when the window is opened, the rope is still in the extended state at the moment, when the window is changed from being opened to being closed, when the rope is not stretched by external force, the rope moves towards the installation seat under the action of the reset spring, so that the rope is always in the extended state, and the rope is always in the extended state, so that the phenomenon that the rope is clamped by the window due to twisting can be avoided, and then when the consumer closed the window, need not additionally pay close attention to the state of rope, increase the comfort level of use, simultaneously two mount pads if all set up the activity chamber, reset spring and movable block, make the length that the rope can extend increase, and then make the degree that the window can be opened increase, reduce reset spring's compression simultaneously, because the window probably opens for a long time, reset spring will be in compression state for a long time promptly, can know by the nature of spring that the atress is less than the thirty percent that can bear the stress the elasticity of spring can not have great influence to the elasticity of spring the biggest, increase reset spring's live time, increase the live time that the power prevents weighing down the lock promptly, and then the cost is reduced.

The utility model discloses further set up to: the mounting seat is provided with a round hole for the rope to pass through, and the round hole extends to be communicated with the movable cavity.

Through adopting above-mentioned technical scheme, the setting up of round hole makes inside the rope can get into the mount pad to be connected with the movable block, and then satisfy the rope pulling movable block and remove, compression reset spring's effect finally makes reset spring reset the rope.

The utility model discloses further set up to: the installation seat is provided with an installation block extending along the outer side, and the installation block is provided with an installation hole used for installing the installation seat on a window sash or a window frame.

Through adopting above-mentioned technical scheme, the setting up of installation piece and mounting hole makes things convenient for the consumer to fix the mount pad on casement or window frame when the installation is prevented weighing down the lock, does not need extra erection equipment, and accessible screw passes the mounting hole, fixes the mount pad.

The utility model discloses further set up to: the mounting blocks are respectively arranged at the front end and the rear end of the mounting seat along the telescopic direction of the rope.

Through adopting above-mentioned technical scheme, when the window is in the open mode, the mount pad is in the state by the rope pulling, and its pulling force provides for the rope, so install two installation pieces respectively at the mount pad along the flexible direction of rope, increase the stability of mount pad.

The utility model discloses further set up to: the movable block on be provided with the reference column and the rope be fixed in on the reference column, reset spring be cylinder compression spring, cylinder compression spring cover is located the reference column and is located between movable block and the mount pad is inside.

Through adopting above-mentioned technical scheme, the reference column is used for increase and reset spring's area of contact, simultaneously for reset spring's flexible guide effect that provides, uses the difficult degree that cylinder compression spring can reduce the installation, only need locate the rope with cylinder compression spring cover and be in the activity intracavity, just can accomplish the reseing of rope, and adopt the pressure spring and do not adopt the extension spring then to reduce the usage space in activity chamber.

The utility model discloses further set up to: the mounting seat comprises a substrate and longitudinal side wings positioned on two longitudinal sides of the substrate, the longitudinal side wings are bent inwards to form movable cavities with the substrate, the two transverse sides of the substrate are respectively provided with a transverse side wing, each transverse side wing is provided with a primary bending part and a secondary bending part, a transverse opening of each movable cavity is sealed by the primary bending part, and the secondary bending parts are used as mounting blocks.

By adopting the technical scheme, the mounting seat is formed by the base plate, the transverse side wing and the longitudinal side wing, and the movable block and the reset spring are arranged in the movable cavity firstly and then the movable cavity is sealed by the longitudinal bending.
