The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-9: the utility model provides a high bearing hinge of strenghthened type, includes through the mutual articulated long 1 of a plurality of rivets, well 2, short 3, pull rod 4 and kerve 5, the bottom surface of kerve 5 is formed with a plurality of counter sink, installs a plurality of in the middle of the counter sink be used for with section bar complex locking screw 6, the top surface of locking screw 6 and the mutual parallel and level of bottom surface of kerve 5. In the bottom groove 5, a slider 10 is further slidably disposed, one end of each of the middle support 2 and the short support 3 is hinged to the slider 10, wherein the rivet used for hinging the middle support 2 and the slider 10 is a step rivet 7 having a layered structure (the step rivet 7 belongs to the existing product, and is not described herein again).

The reinforced bar 8 is preferably made of stainless steel, one end of the reinforced bar 8 is hinged with the short support 3, the other end of the reinforced bar is provided with a U-shaped open slot 801, and the step rivet 7 used by the middle support 2 is positioned in the U-shaped open slot 801; u type open slot 801 is used for avoiding when the hinge opens and close, and the interference problem appears in the activity of stiffener 8.

Further, the step rivet 7 is located in the middle of the U-shaped opening groove 801, and the outer diameter of the step rivet matches with the width of the U-shaped opening groove 801.

Furthermore, the hinge point of the short branch 3 and the sliding block 10 is A, the hinge point of the short branch 3 and the pull rod 4 is B, and the hinge point of the reinforcing rod 8 and the short branch 3 is C, wherein, LAC, LBC is approximately equal to 2.

As shown in fig. 2 and 4, the sliding block further comprises a supporting filler strip 9, wherein the supporting filler strip 9 is composed of a supporting part 901 and a filler plate 902 which are integrally formed, the filler plate 902 is attached to the top edge 501 of the bottom slot 5, and rivets corresponding to the middle branch 2 and the short branch 3 penetrate through the filler plate 902 so that the supporting filler strip 9 is connected with the sliding block 10; the length of the backing plate 902 is longer than that of the slider 10, and the supporting part 901 is positioned below the part of the backing plate 902 exceeding the slider 10 and is arranged in the bottom groove 5 together with the slider 10; grooves 9011 are further formed in the left side and the right side of the supporting portion 901, the grooves 9011 can be matched with the top edge 501 of the bottom groove 5, certain guiding capacity is provided for linear sliding of the slider 10, and the slider 10 is prevented from being deviated. Because the backing plate 902 of the supporting backing strip 9 is always attached to the top edge 502 of the bottom groove 5 when the supporting backing strip 9 slides along with the slider 10, the middle support 2 and the short support 3 can be separated from the top edge 501 of the bottom groove 5, so that the condition of contact friction is avoided, the service life of the whole structure is prolonged, and on the other hand, the backing plate 902 attached to the top edge 501 also increases the supporting area between the slider 10 and the hinge, so that the bending resistance and the downward tilting resistance of the hinge under the action of the gravity of the window sash can be enhanced.

Furthermore, two limiting strips 9021 are arranged below the cushion plate 902 of the supporting cushion strip 9 in parallel, the positions of the limiting strips 9021 are matched with the grooves 9011, the functions of the limiting strips 9021 are the same as those of the grooves 9011, and the limiting strips are used for being matched with the top side edge 501 to provide certain guiding capability for the linear sliding of the sliding block 10.

Furthermore, an abdicating notch 9012 is formed below the supporting portion 901 of the supporting backing strip 9, and the abdicating notch 9012 is used for preventing the head of the locking screw 6 from affecting the slider 10, and ensuring that the hinge can be normally closed.

As shown in fig. 5 and 6, a friction block mounting groove is formed on the bottom surface of the slider 10, a friction block 1001 preferably made of copper is disposed in the friction block mounting groove and attached to the bottom surface of the bottom groove 5, a tightening screw 1002 for engaging with the friction block 1001 is further disposed above the slider 10, and the friction block 1001 can be slightly pressed in the bottom groove 5 by tightening the tightening screw 1002, so as to adjust the friction force between the slider 10 and the bottom groove 5, so that the slider can have a certain damping feeling during sliding, thereby improving the user experience.

Further, in this embodiment, the tightening screw 1002 is designed at a position between the middle support 2 and the short support 3, which is relatively difficult to adjust and is easily blocked by the upper reinforcing rod 8, so the design further provides a fabrication hole 802 on the reinforcing rod 8, and the user can open the hinge to the position where the fabrication hole 802 and the tightening screw 1002 are aligned, and then the user can tighten the tightening screw 1002 through the fabrication hole 802 by passing an auxiliary instrument through the fabrication hole 802.

Further, the sliding block 10 is a cast-in sliding block, the sliding block body on the outer side of the sliding block is made of engineering plastic materials, a stainless steel piece is cast in the center in an embedded mode, and a screw hole is formed in the stainless steel piece and used for being matched with the tightening screw 1002; the sliding block with the cast-in structure can not only exert the advantage of wear resistance of engineering plastics, but also enhance the strength of the whole structure, and is not easy to deform or break even after long-time use, thereby avoiding the falling condition of the window sash and improving the safety.

Furthermore, a bump for limiting the sliding position of the slider 10 is formed on the bottom slot 5, and when the slider 10 abuts against the bump, the hinge is in a fully opened state.

Furthermore, a boss 503 is punched at the end of the bottom slot 5, and one end of the long branch 1 is hinged with the bottom slot 3 through the boss 503. In addition, the height of the boss 503 is slightly higher than the height of the bottom groove, which also serves to avoid friction problems between the long leg 1 and the top side edge 501 of the bottom groove 5.

Furthermore, the device also comprises a detachable guide top corner 11 fixed at the head end of the bottom groove 5.

The preferred L type structure that adopts of guide apex angle 11 of this design, the tip shape of above-mentioned pull rod 4 matches rather than each other, compares in the guide apex angle 11 of traditional V type structure, this kind of design that has a straight face of L type structure, can make the hinge provide certain conflict ability for the casement under the closed state, avoids the casement to move towards indoor activity under the influence of blowing, causes the reverse activity of hinge to appear and damages the problem.

Furthermore, an inclined stop 401 is formed at the end of the pull rod 4, and when the pull rod 4 is inserted into the sash profile and the stop 401 abuts against the side edge of the sash profile, it means that the pull rod is already mounted in place, and the operator can directly perform the next locking assembly (the sash profile is an existing product, and is not shown in the drawings).

Furthermore, in the middle of each pin joint of this design, still add annular gasket for compensate the difference in height that the articulated elements exists when assembling.

Furthermore, reinforcing ribs are formed on the long branches 1 in a stamping mode.
