Background

Traditional doors and windows are driven to open and close by hardware connectors such as sliding supports and hinges. For some casement windows with hinges, when a window sash is opened, force is transmitted to a moving mechanism through a supporting arm of the hinge, and the opening and closing angle of the window sash depends on the sliding distance of a sliding block in the moving mechanism on a sliding rail, so that the whole size of the hinge needs to be designed to be larger to meet daily required amplitude of opening and closing of a door and a window, and the difficulty of installation and production is increased.

Chinese patent CN216476841U discloses a hidden hinge for vertical hinged door and window, it controls the angle of opening and closing of the support piece through the cooperation between first arc chute and first locating part, second arc chute and second locating part to replace original slide rail, slider subassembly, reduced the length of bottom plate, avoided the whole volume of hinge too big. However, in the practical use process, the weight of the door and window can be pressed on the hinge, especially for the door and window after opening, the structure in the hinge needs to bear a large weight, and when part of the structure is subjected to downward pressure for a long time, the hinge point in the hinge structure is easy to loosen.

Detailed Description

The utility model will be further described with reference to examples and drawings, to which reference is made, but which are not intended to limit the scope of the utility model.

It should be noted that, in the present utility model, unless explicitly stated and limited otherwise, terms such as "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances. Furthermore, in the present utility model, unless expressly stated or limited otherwise, a first feature "up" or "down" on a second feature may include both the first and second features being in direct contact, or may include both the first and second features not being in direct contact but being in contact through additional features therebetween.

As shown in fig. 1, a door and window hinge, including bottom plate 1, articulated in the long cantilever 2 and the short cantilever 3 of bottom plate 1, the one end of short cantilever 3 articulates there is the support piece 4, the one end of long cantilever 2 articulates with the middle part of support piece 4, bottom plate 1 is provided with arc spout 5, the short cantilever 3 fixedly connected with gag lever post 6, the one end of gag lever post 6 passes arc spout 5 and fixedly connected with spacing head 7, the diameter of spacing head 7 is greater than the width of arc spout 5, still be equipped with stopper 8 on bottom plate 1, stopper 8 is located the position between long cantilever 2 and the short cantilever 3 and is close to short cantilever 3, one end of bottom plate 1 is equipped with spacing post 9, the one end of support piece 4 is equipped with can with spacing breach 10 with spacing post 9 complex, when short cantilever 3 is in the swing, gag lever post 6 can be along arc spout 5 removal, until one side of short cantilever 3 supports stopper 8 or spacing breach 10 supports spacing post 9.

In the structure, a sliding arm 11 is further connected between the long cantilever 2 and the bottom plate 1, the outer end of the sliding arm 11 is hinged to the long cantilever 2, the inner end of the sliding arm 11 is hinged to a sliding block 12, the bottom plate 1 is provided with a section of linear sliding groove 13 along the length direction of the bottom plate 1, the linear sliding groove 13 is located between the long cantilever 2 and the short cantilever 3, and the sliding block 12 is slidably connected to the linear sliding groove 13. The long cantilever 2 and the bottom plate 1 are connected through the sliding arm 11, so that the long cantilever 2 can obtain more reliable supporting acting force, and the structural strength of the whole door and window hinge is improved.

Preferably, the spacing head 7 is close to the bottom surface of the base plate 1 with a gap between them of 2-4mm, preferably 3mm. Therefore, when the door and window hinge is normally opened and closed, the limiting head 7 does not excessively rub the bottom surface of the bottom plate 1, abrasion is reduced, but when the door and window hinge is opened and bears larger acting force, the limiting head 7 can better bear force upwards to abut against the bottom surface of the bottom plate 1, so that the problem of the stress of the hinge point of the short cantilever 3 and the bottom plate 1 is solved.

In order to facilitate the fixing of the door and window structure, one end of the supporting piece 4 is also fixedly connected with a baffle piece 14 perpendicular to the supporting piece. In addition, the arc of the arc chute 5 in the present embodiment is greater than 90 degrees.

When the door and window hinge provided by the embodiment is used, the door and window structure can be fixedly arranged on the supporting piece 4, a plurality of connecting holes are reserved on the supporting piece 4, and the baffle piece 14 at one end of the supporting piece 4 is fixedly connected with the door and window structure so as to ensure better stability. When the door and window is closed, the whole door and window hinge is in a folded state as shown in fig. 4, when the door and window is pushed open, the long cantilever 2 and the short cantilever 3 start to swing, the sliding block 12 also moves along the linear sliding groove 13, meanwhile, the limiting rod 6 slides along the arc sliding groove 5 to reach the state as shown in fig. 1, when the door and window is pushed to the limit position, one side of the short cantilever 3 abuts against the limiting block 8, and meanwhile, the sliding block 12 also slides to one end position of the linear sliding groove 13 to reach the state as shown in fig. 3. At this time, the supporting piece 4 plays a role of mainly bearing the weight of a door and a window, the acting force of the door and the window can be transmitted to the long cantilever 2 and the short cantilever 3, and the middle part of the short cantilever 3 can be practically pressed at the edge of the bottom plate 1, so that the other end of the short cantilever 3 is subjected to the upwarp acting force, but the limiting head 7 is arranged, and can be propped against the bottom surface of the bottom plate 1 upwards, so that the problem that the hinge point structure of the short cantilever 3 and the bottom plate 1 is excessively stressed is avoided, and the problem that the part is easy to loosen is avoided. Similarly, for the long cantilever 2, the force applied to the long cantilever can be shared by the sliding arm 11, the upwarp force applied to the inner end of the sliding arm 11 can be limited by the sliding block 12, and the sliding block 12 and the linear sliding groove 13 can be matched by adopting an I-shaped sliding rail type structure, so that the problem that the hinge point position of the sliding arm 11 and the sliding block 12 is too stressed is avoided, and further the problem that the part is easy to loosen is avoided.

Therefore, the door and window hinge structure provided by the utility model has good strength, can alleviate the loosening of the hinge part after long-term use, and has great practical application value and market popularization prospect.

In order to make it easier for a person skilled in the art to understand the improvements of the present utility model with respect to the prior art, some of the figures and descriptions of the present utility model have been simplified, and the above-described embodiments are preferred implementations of the present utility model, but in addition, the present utility model may be implemented in other ways, and any obvious substitution is within the scope of protection of the present utility model without departing from the concept of the present technical solution.
