Description

Technical Field

[0001] The utility model relates to the technical field of door and window hinges, in particular to a quick-install invisible hinge. Background Art

[0002] Invisible hinges (i.e. hidden hinges) are used to connect door and window sashes and door and window frames to achieve the opening and closing of doors and windows. Invisible hinges usually include sash mounting plates, support plates, load-bearing plates and bottom plates stacked up and down. The bottom plate is fixed to the door and window frame by screws, the sash mounting plates are fixed to the door and window sashes by screws, and the two ends of the riveted load-bearing plates and support plates are respectively connected to the bottom plate and sash mounting plates. Usually, a door and window needs to be installed with a set of hinges on the top and bottom.

[0003] The publication number is "CN 109403770 B". An invisible hinge for aluminum-wood composite doors and windows, comprising a fan mounting piece, a support piece, a load-bearing piece and a bottom plate stacked up and down, one end of the load-bearing piece is riveted to the bottom plate by a first rivet, the other end of the load-bearing piece is slidably connected to the fan mounting piece, one end of the support piece is riveted to the fan mounting piece by a second rivet, the other end of the support piece is slidably connected to the bottom plate, the middle part of the support piece is riveted to the load-bearing piece by a third rivet, the outer end of the fan mounting piece is connected to a mounting seat, the outer end of the bottom plate is provided with a plurality of connecting holes, and the mounting seat and the connecting holes are used to realize the invisible hinge. The connection with the door and window hardware system is that the base plate is fixed to the door and window frame through a number of anti-warping units. Each anti-warping unit includes an anti-warping piece and a hexagonal rivet. The anti-warping piece is arranged between the base plate and the door and window frame. However, in the above-mentioned documents and most of the invisible hinges on the market, the base plate needs to be connected to the window frame through a number of anti-warping units or bolts, which makes the installation steps complicated. In addition, since the part to be installed is often in the angle or corner between the window frame and the window sash, it is inconvenient for the staff to install and it is difficult to disassemble during maintenance and replacement. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a quick-install invisible hinge with fewer installation steps and convenient maintenance, replacement and disassembly in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-install invisible hinge, comprising a fan mounting plate, a support plate, a load-bearing plate and a base plate stacked up and down, one end of the load-bearing plate being riveted to the base plate by a first rivet, the other end of the load-bearing plate being slidably connected to the fan mounting plate, one end of the support plate being riveted to the fan mounting plate by a second rivet, the other end of the support plate being slidably connected to the base plate, the middle part of the support plate being riveted to the load-bearing plate by a third rivet, and characterized in that a matching plate is provided on a side of the base plate away from the load-bearing plate, and a quick-install structure for fixing the base plate to the connecting profile is provided between the matching plate and the base plate.

[0006] The above technical solution is adopted: during installation, the sash mounting plate is fixed on the window sash, and the bottom plate is inserted into the window frame profile. At this time, the matching plate is located between the bottom plate and the window frame. Through the setting of the quick-install structure, the bottom plate is fixed on the profile to complete the installation. Compared with the prior art that the bottom plate needs to be connected to the window frame through a number of anti-warping units or bolts, the utility model only needs to use the quick-install structure to achieve quick installation, and reduces the difficulty of installation for the staff.

[0007] The utility model is further configured as follows: the quick-installation structure comprises a mounting insert, and the outer end of the mounting insert is provided with a mounting portion for causing the mounting insert to slide and engage with the matching piece, thereby fixing the bottom plate on the connecting profile.

[0008] The above technical solution is adopted: by setting the installation plug, when the base plate is inserted into the window frame profile, the matching piece is located between the base plate and the window frame, the installation plug is inserted, and it is snap-fitted with the matching piece. At the same time, by setting a mounting portion at the outer end of the installation plug, the installation portion is no longer located at the angle between the window and the window frame. The base plate can be conveniently fixed on the profile, thereby realizing quick installation and reducing the difficulty of installation for the staff.

[0009] The utility model is further configured as follows: the mounting portion comprises a mounting protrusion, the mounting protrusion is provided with a transverse threaded hole, and the mounting insert is provided with a screw placement groove at one side corresponding to the transverse threaded hole.

[0010] The above technical solution is adopted: through the setting of the mounting protrusion and the transverse threaded hole, when the mounting plug and the matching piece are snap-fitted, only one screw needs to be inserted into the transverse threaded hole to snap-fit ​​and fix the mounting plug and the matching piece, so that the base plate is installed in the profile, ensuring its firmness and stability. At the same time, the installation steps are reduced and the operation is simple and convenient; by providing a screw placement groove on the matching piece, it is easier to install the screw.

[0011] The utility model is further configured as follows: a sliding groove is provided on one side of the matching piece, and the sliding groove is an inclined surface; a sliding block is provided on one side of the installation plug piece, and the sliding block is an inclined surface matching the inclined surface of the sliding groove; the sliding block can slide and cooperate along the sliding groove.

[0012] The above technical solution is adopted: through the setting of the sliding groove and the sliding block, since the sliding groove and the sliding block are corresponding inclined surfaces, which are equivalent to parent and child parts, when the installation plug is inserted into the sliding groove for clamping, it can be adjusted according to the width of the profile. If the profile is narrow, the installation plug can be adjusted outward along the sliding groove. If the profile is wide, the installation plug can be adjusted inward along the sliding groove. After adjusting to the appropriate position, the screws are inserted into the transverse threaded holes for fixing to complete the installation, thereby realizing the function of convenient installation, while improving its versatility and ensuring its installation effect.

[0013] A further configuration of the utility model is that a limiting portion is provided at the outer end of the bottom plate, and the limiting portion can abut against the mounting protrusion.

[0014] By adopting the above technical solution, the problem of inserting the installation plug too deeply can be avoided when the installation plug is clamped to the matching piece by setting the limiting part.

[0015] The utility model is further configured as follows: a guide groove for sliding connection of the support piece is provided on the bottom plate, a through hole is formed in the middle of the installation insert piece after being engaged with the matching piece, and the through hole is communicated with the guide groove.

[0016] By adopting the above technical solution, through the provision of the through hole, and the through hole being connected with the guide groove, the quick-install structure will not interfere with the reciprocating motion of the support piece in the guide groove, thereby ensuring its use effect.

[0017] The beneficial effects of the utility model are as follows: by setting the quick-install structure, the bottom plate can be easily installed in the window frame profile, thereby achieving the effect of fewer installation steps and convenient maintenance, replacement and disassembly.
