Abstract

The utility model relates to an adjustable limit support of a casement window, which solves the problems of serous abrasion, non-adjustable and poor safety of an existing limit device used for a window. The adjustable limit support comprises a frame gate piece which is fixed on a window frame, and a supporting rod whose end is hinged with the frame gate piece, the technical main points are that the other end of the supporting rod is hinged with a slide block which is assembled in a slideway groove of a casement section in a sliding mode, a narrow slot whose one end is opened is arranged on the middle portion of the slide block along the length direction, the open end of the narrow slot is provided with a guide skewed slot, an adjustable screw is arranged on one end of the slide block, which is opposite to the guide skewed slot, and the adjustable screw is contacted with the oblique plane of the guide skewed slot. The adjustable limit support has simple structure, convenient limit and adjustment, and improves the safety and the stability of the window opening, and obviously improves the positioning effect and the service life. The adjustable limit support is suitable for an inner flat-opening and lower hung window, a lower hung and inner flat-opening window, an inner flat-opening and outer flat-opening window and the like.

Description

The adjustable limited support of casement window

Technical field

The utility model relates to a kind of window stopping means, the adjustable limited support of particularly a kind of casement window easy to adjust simple in structure, spacing.It is applicable to inner flat opening bottom-hung window, following outstanding casement window opening inwards, casement window opening inwards and outer casement window etc.

Background technology

At present, will be with inner flat opening bottom-hung window, when the window of types such as outstanding casement window opening inwards, casement window opening inwards and outer casement window is opened down, need when having certain opening angle, be fixed, reach the purpose of daylighting and ventilation, realize the important component of this positioning function and limited support is a window with this.Traditional limited support structure includes two bearings and a connecting rod, one of them bearing be fixedly installed on window frame or the appropriate location of other fixed components of closing on, another bearing is fixedly installed on the appropriate location of sash, wherein the two ends of connecting rod are connected on the fixed bearing of sash and window frame, be that two ends can be with the keying campaign of sash, can relatively rotate with fixed bearing again simultaneously, this stopping means is to rely on the frictional force of the chute that is provided with on connecting rod and the fixed bearing to reach spacing purpose.But, after the long-time use of this structure, fixed bearing upper hopper chute serious wear, the locating effect of limited support significantly descends, reduction of service life.Run into wind-force when excessive, be that the thrust that is subjected to of sash is greater than frictional force, window is closed suddenly, safety and the reliability can not the better guarantees door and window under opening, used, damage the component on the door and window easily, near when serious the entail dangers to door and window personal security is shaken bad glass, brings loss to the user.Simultaneously, above-mentioned stopping means is not had an adjustability, promptly in its course of work, can not regulate its spacing size according to its wear condition, and guaranteeing normal limit function, the reduction in application life must cause produces the increase of giving birth to this and the waste of resource.So it is imperative to improve this type of stopping means.

The utility model content

The purpose of this utility model provides the adjustable limited support of a kind of casement window, and it has solved problems such as serious wear that existing window exists with stopping means, unadjustable, poor stability.It is simple in structure, spacing easy to adjust, has strengthened the security and stability that window is opened, and significantly improves locating effect and application life.

The purpose of this utility model is achieved in that this casement window comprises frame lock dog and the end support bar hinged with it that is fixed on the window frame with adjustable limited support, its technical essential is: the other end of described support bar and the slidingly assemble slide block in the sash profile slide groove is hinged, the narrow groove of one end opening is set along its length at the central part of slide block, the openend of narrow groove is provided with the importing skewed slot, an end relative with importing skewed slot at slide block is provided with adjustment screw, and adjustment screw is contacted with the inclined-plane of described importing skewed slot.

Described slide block and the contacted two sides of sash profile slideway groove face are provided with boss respectively.

Because the central part of the utility model slide block is provided with along its length and has the narrow groove of the opening that imports skewed slot, so slide block can screw in the damping value size of how much controlling self of narrow groove by the adjustment screw of its end, this has not only solved problems such as serious wear that existing window exists with stopping means, unadjustable, poor stability, and strengthened the security and stability that window is opened, significantly improve locating effect and application life.If at slide block and the contacted two sides of sash profile slideway groove face boss is set respectively, then can also increases the wall thickness of slide block and slideway groove face contact position, the application life of further improving slide block.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of concrete structure schematic diagram of the present utility model;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the left view of Fig. 2;

Sequence number explanation among the figure: 1 frame lock dog, 2 support bars, 3 slide blocks, 4 adjustment screw, 5 skewed slots, 6 narrow grooves, 7 bearing pins, 8 boss, 9 screws.

The specific embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1-Fig. 3.This casement window comprises parts such as frame lock dog 1, support bar 2, slide block 3, adjustment screw 4 with adjustable limited support.Its center lock dog 1 adopts common structure, is fixed on the window frame (not shown) by screw 9.The support bar 2 that is flat-shaped can adopt stainless steel material to make, and is provided with the convex type reinforcing rib in the middle of it.Support bar 2 one ends and frame lock dog 1 are hinged, and the other end utilizes bearing pin 7 and the slide block 3 of slidingly assemble in sash profile slide groove (not shown) hinged.The axle head of bearing pin 7 is pressed into the retaining platform, support bar 2 can only be rotated around bearing pin 7, but can not break away from bearing pin 7.Slide block 3 can be made by the rigid plastics with abrasion resistance, and itself and the contacted two sides of sash profile slideway groove face are the locating effect and the application life of improving slide block 3, and the boss 8 that increases its wall thickness can be set respectively on the surface, two sides.At the central part of slide block 3 the narrow groove 6 of an end opening is set along its length, the openend of narrow groove 6 is provided with and imports skewed slot 5, and an end relative with importing skewed slot 5 at slide block 3 is provided with adjustment screw 4, and adjustment screw 4 is contacted with the inclined-plane of importing skewed slot 5.The width of importing skewed slot 5 and the degree of depth are according to actual mode of occupation setting.Regulate for convenient, the head of this adjustment screw 4 can be interior hexagon, and its afterbody requires to be set to cone structure for adapting to the inclined-plane that imports skewed slot 5.

User's turn adjustment screw on demand 4, adjustment screw 4 screw in or screw out narrow groove 6 makes it produce elastic deformation, thereby makes the both sides with respect to sash profile slideway groove face of slide block 3 increase or reduce mobile damping value, with the convenient reliable sash location that obtains.
