As shown in fig. 1, the push-out sliding support hinge according to the embodiment of the first aspect of the present utility model is a hardware, and the push-out sliding support hinge includes at least one fork-shaped movable structure 100 and two connecting rods 200, where the two connecting rods 200 are parallel to each other, each connecting rod 200 is provided with a mounting groove 210 in the length direction, and the fork-shaped movable structure 100 is located between the two connecting rods 200 and connected with the two mounting grooves 210. The two connection rods 200 are respectively provided with mounting holes 211 for connecting a frame (not shown in the drawings) and a sash (not shown in the drawings), so that the frame of the casement door and window and the sash of the casement door and window can be mounted and connected through the push-out type sliding support hinge, and each outer side surface of the sash needs to be assembled with the frame through the push-out type sliding support hinge.

In the sliding door and window, the installation surface of the frame body is opposite to the installation surface of the fan body, and the outer bottoms of the two connecting rods 200 of the push-out sliding support hinge are respectively used for connecting the frame body and the fan body, so that the outer bottoms of the two connecting rods 200 are required to be arranged opposite to each other. In order to achieve the above-mentioned structure, the notches 212 of the two mounting grooves 210 are disposed in opposite directions, and in this case, the bottoms of the mounting grooves 210 are the inner bottom surfaces of the connecting rods 200, and the two connecting rods 200 are not on the same horizontal plane.

When the sliding door and window are required to be assembled, one connecting rod 200 of the four push-out sliding support hinges is fixedly connected to four mounting surfaces of the fan body, then the other connecting rod 200 of the push-out sliding support hinge positioned at the bottom of the fan body is placed in a groove cavity of the bottom surface of the frame body and is fixedly connected with the frame body, then the other connecting rods 200 of the push-out sliding support hinges positioned at the left side and the right side of the fan body are placed in corresponding groove cavities of the frame body and are fixedly connected with the frame body, and finally the other connecting rod 200 of the push-out sliding support hinge positioned at the top of the fan body is placed in corresponding groove cavities of the frame body and is fixedly connected with the frame body, so that the assembling of the sliding door and window is completed.

Specifically, the fork-shaped movable structure 100 includes a first cantilever 110 and a second cantilever 120, where the middle part of the second cantilever 120 is hinged to the middle part of the first cantilever 110 through a pin 130, and at this time, the fork-shaped movable structure 100 has four overhead ends, and the first cantilever 110 and the second cantilever 120 can be far away from each other or close to each other around the pin 130, so as to implement the unfolding or closing of the fork-shaped movable structure 100. The head ends of the first cantilever 110 and the second cantilever 120 are fixedly hinged in the mounting slots 210 of the two connecting rods 200 through the first connecting member 140, respectively, and the connection line between the head-end hinge point of the first cantilever 110 and the head-end hinge point of the second cantilever 120 is orthogonal to the connecting rods 200 to define the head-end positions of the two cantilevers.

Meanwhile, the distal ends of the first and

second cantilevers

110 and 120 are respectively hinged with sliders 300 through second connectors 150, and the two sliders 300 are respectively slidably connected along the mounting grooves 210 of the two connection rods 200, and at this time, the connection line between the distal hinge point of the first cantilever 110 and the distal hinge point of the second cantilever 120 is orthogonal to the connection rods 200 to define the distal positions of the two cantilevers. The slider 300 is preferably a brass member, but may be made of other materials, without specific limitation, and is within the scope of protection.

Because two of the overhead ends of the fork-shaped movable structure 100 are respectively fixedly hinged to two of the connecting rods 200, and the other two overhead ends of the fork-shaped movable structure 100 are respectively slidably hinged to two of the connecting rods 200 through respective sliding blocks 300, the two connecting rods 200 can be far away from or close to each other under the unfolding or closing of the fork-shaped movable structure 100, so that the opening or closing of the fan in the sliding door and window can be realized.

As shown in fig. 2, each of the sliding blocks 300 is provided with a sliding groove 310 on two long side vertical walls thereof, the sliding groove 310 extends along the length direction of the sliding block 300 and penetrates through two wide side vertical walls of the sliding block 300, each of the mounting grooves 210 is provided with two sliding edges 213 along the length direction thereof, and the sliding edges 213 are located at the notch 212 of the mounting groove 210, that is, the two sliding edges 213 can jointly define the notch 212. The sliding groove 310 is slidably connected with the sliding edge 213 in a clamping manner, so that the sliding block 300 can be slidably connected with the connecting rod 200.

With the above structure, since the sliding surfaces of the slider 300 and the connecting rod 200 are not bottoms of the installation grooves 210, but the sliding surfaces of the present utility model are located at two sides of the notch 212 of the installation groove 210, the bottom surface of the slider 300 can be elevated above the bottoms of the installation grooves 210, and even if the inner bottom surface of the connecting rod 200 is attached with particulate impurities such as sand, the sliding of the slider 300 is not affected, so that the fork-shaped movable structure 100 can slide smoothly along the connecting rod 200, and the service life of the push-out sliding hinge is effectively prolonged.

Further, in order to make the slider 300 better avoid the particle impurities on the bottom of the installation groove 210, a clearance groove 320 is formed on the bottom surface of the slider 300, and the clearance groove 320 extends along the length direction of the slider 300 and penetrates through two broad-side standing walls of the slider 300. Since the position of the widthwise central line of the installation groove 210 is more likely to adhere to the particulate impurities, it is preferable that the clearance groove 320 is provided at a centering position of the slider 300, in which case the widthwise central line of the clearance groove 320 coincides with the widthwise central line of the slider 300.

As shown in fig. 1, in some embodiments of the present utility model, in order to limit the expansion range of the fork-shaped movable structure 100 to limit the opening degree of the sash of the sliding door and window, a stopper 400 is connected to the mounting groove 210, and the stopper 400 is located on the moving path of the slider 300 and is disposed between the slider 300 and the first connecting member 140. When the push-out type sliding hinge is unfolded, the slider 300 slides towards the first connecting piece 140, and once the slider 300 abuts against the limiting block 400, the push-out type sliding hinge is unfolded in place, and the unfolding cannot be continued.

As shown in fig. 4, further, the mounting groove 210 is provided with a plurality of adjusting holes 214 along its length direction for connecting the limiting block 400, if the limiting block 400 is connected to different adjusting holes 214, it represents that the sliding block 300 has different maximum sliding distances, so that the installer can adjust the maximum unfolding amplitude of the push-out sliding hinge according to the actual requirement of the user, thereby adjusting the maximum outward translation distance of the sliding door and window sash body.

As shown in fig. 3 and fig. 4, the first cantilever 110 and the second cantilever 120 are both in crank structures, and both include a first straight line section 111, a turning section 112 and a second straight line section 113, wherein the turning section 112 is connected with a pin 130 for implementing the hinge connection between the first cantilever 110 and the second cantilever 120, two ends of the turning section 112 are respectively connected with the first straight line section 111 and the second straight line section 113, the first straight line section 111 is parallel to the second straight line section 113, but the first straight line section 111 and the second straight line section 113 are arranged in a staggered manner, i.e. the width center line of the first straight line section 111 is parallel to but does not coincide with the width center line of the second straight line section 113. The first cantilever 110 and the second cantilever 120 are respectively provided with a step structure 500 capable of abutting against each other, the step structure 500 of the first cantilever 110 positioned above extends downward, and the step structure 500 of the second cantilever 120 positioned below extends upward, so that when the fork-shaped movable structure 100 is closed, the first cantilever 110 can abut against the second cantilever 120 through the step structure 500, and the closing degree of the two can be limited, so that the situation that the two can not be closed due to the closing offside can be avoided. When the fork-shaped movable structure 100 is closed, the inner standing wall 101 of the first cantilever 110 is aligned with the inner standing wall 101 of the second cantilever 120 along a straight line, and the outer standing wall 102 of the first cantilever 110 and the outer standing wall 102 of the second cantilever 120 are also aligned along a straight line and together form the outer edge of the fork-shaped movable structure 100.

Further, the outer edge of the fork-shaped movable structure 100 is parallel to the extending direction of the connecting rod 200 when the fork-shaped movable structure is closed, so that when the push-out sliding support hinge is completely closed, the outer edge can be abutted with the connecting rod 200 without generating a gap, and the stability and the sealing performance of the push-out sliding support hinge are effectively improved.

When the size of the sliding door is large, more than one fork-shaped movable structure 100 needs to be arranged on two connecting rods 200, so as to prevent the sliding hinge from being deformed due to overlarge bearing. The push-out sliding hinge is generally provided with two fork-shaped movable structures 100, but the number of the fork-shaped movable structures 100 is not limited in the utility model, all the fork-shaped movable structures 100 are sequentially connected to two connecting rods 200, and two adjacent fork-shaped movable structures 100 are respectively arranged at intervals along the extending direction parallel to the connecting rods 200.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
