Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention, and the described embodiments are merely a subset of the embodiments of the present invention, rather than a complete embodiment. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1
As shown in fig. 1 to 6, the inward-opening inward-falling hinge provided in this embodiment mainly includes a frame mounting plate 1, a first arm 2 and a second arm 3, wherein the first arm 2 and the second arm 3 are hinged at a middle portion to form a scissor-type rotating mechanism. The specific application principle of the frame mounting plate 1, the first arm 2 and the second arm 3 can be referred to in the prior art, and is not described in detail herein.
In this embodiment, a first turnover mechanism is disposed between the first arm bar 2 and the frame mounting plate 1, and a second turnover mechanism is disposed between the second arm bar 3 and the frame mounting plate 1; therefore, when the hinge is installed and used, the rotating mechanism formed between the first arm rod 2 and the second arm rod 3 can perform overturning motion relative to the frame installation plate 1; that is, when the sash structural member is mounted on the corresponding frame structural member through the hinge in this scheme, the "fall-in" operation of the sash structural member with respect to the frame structural member can be achieved.
Specifically, in this embodiment, the first turnover mechanism mainly includes a turnover support block 4, a first through hole 11 disposed on the frame mounting plate 1, a second through hole 21 disposed on the first arm 2, and a first pin 41.
As a preferable scheme, in this embodiment, the flip support block 4 is configured as a rectangular structure, a mounting hole into which one end of the first pin 41 is inserted is formed in the middle of the flip support block, and the first pin 41 is connected to the flip support block 4 passing through the first through hole 11 after passing through the second through hole 21, so that the frame mounting plate 1 and the first arm lever 2 are clamped between the first pin 41 and the flip support block 4. In this structure, when the first arm 2 rotates around the first pin 41, its direct rotational force point falls on the flip support block 4 instead of the frame mounting plate 1.
Further, the opening length of the first via hole 11 is matched with the length of the turning support block 4, so that the phenomenon of relative sliding between the turning support block 4 and the frame mounting plate 1 cannot occur in the actual use of the hinge; the relative sliding referred to herein is mainly the sliding movement of the roll-over support block 4 along the length direction of the frame mounting plate 1, and this relative sliding movement may cause the hinge to swing left and right when in use, which affects the stability of the hinge when in use. The opening width of the first via hole 11 is larger than that of the turning support block 4, so that a first avoidance space is formed, and an 'inward-falling' structural foundation at the first arm lever 2 is provided.
As a preferable scheme, in this embodiment, an inclined structure surface 42 is disposed on the outer side surface of the flip support block 4, and an inclined lower end of the inclined structure surface 42 is disposed near the bottom end of the flip support block 4; the "outer side surface", "inner side surface", "bottom end" and "top end" in this embodiment are determined according to the state of the hinge when actually mounted and used. The inclined structural surface 42 and the inner side wall of the first via hole 11 form the first avoidance space therebetween.
As one of the application examples, in the present embodiment, the shape and thickness of the top end of the flip support block 4 are adapted to the shape and thickness of the first via hole 11, so that the fan structural member and the frame structural member can operate smoothly in a normal state. And during the inward-falling overturning operation, the overturning supporting block 4 can overturn to enable the inclined structure surface 42 to be opposite to the inner side wall of the first via hole 11, so that a gradually enlarged first avoiding space is formed, and the inward-falling operation of the fan structural member relative to the frame structural member is realized.
Preferably, a plurality of anti-falling projections 43 are further protruded from the bottom end of the flip support block 4. As shown in fig. 1 of this embodiment, the anti-falling-off protrusion 43 is disposed on the inner side surface of the turning support block 4 along the length direction of the turning support block 4, so as to prevent the turning support block 4 from accidentally falling off from the frame mounting plate 1 when the force is applied too much, and the hinge can be used more safely and reliably. In other application examples, the anti-falling-off protrusion 43 may also be selectively disposed on the outer side surface of the flip supporting block 4, which is not described herein.
As a preferred application example, as shown in fig. 6, the turning support block 4 is provided in another structure, and the anti-falling projections 43 are provided on the left side surface and/or the right side surface of the turning support block 4. The anti-falling lugs 43 on the left and right sides of the turning supporting block 4 can more effectively prevent the turning supporting block 4 from falling off accidentally on the frame mounting plate 1 in installation and use, and have better anti-overload performance; meanwhile, the assembly between the anti-rotation supporting block 4 and the frame mounting plate 1 on a production line can be facilitated, and the production efficiency can be improved conveniently. Further, in this embodiment, it is preferable that the upper surfaces of the anti-falling projections located on the left and right sides of the turning support block 4 are inclined surfaces, and the lower inclined ends of the inclined surfaces are close to the inclined structural surface 42, so that the anti-falling projections 43 can be better attached to the bottom end surface of the frame mounting plate 1 during the "fall-in" operation of the hinge device.
In addition, as a preferable scheme, the first turnover mechanism in this embodiment further includes a turnover spacer 5, the turnover spacer 5 is disposed between the frame mounting plate 1 and the first arm rod 2, and the first pin 41 is connected to the turnover support block 4 after passing through the turnover spacer 5.
Specifically, the flip pad 5 includes a bottom plate 51, and a first side wall 52 and a second side wall 53 respectively disposed on the outer side and the inner side of the bottom plate 51, so that the flip pad 5 is "U" shaped in side view; the first side wall 52 and the second side wall 53 are disposed toward the frame mounting plate 1, wherein an angle between the first side wall 52 and the bottom plate 51 is matched with an angle between an outer side surface of the frame mounting plate 1 and an upper surface thereof, and a third avoidance space is formed between an angle between the second side wall 53 and the bottom plate 51 and an inner side surface of the frame mounting plate 1. When the inward-falling operation is carried out, due to the existence of the third avoiding space, the fan structural member can carry out the inward-falling operation relative to the frame structural member; due to the design of the first side wall 52, the fan structure cannot be "tipped out" relative to the frame structure.
Furthermore, the second turnover mechanism mainly includes a second pin 31 and a third via hole 32 disposed on the second arm 3. In this embodiment, the second pin 31 includes an operation portion 311 and a connection portion 312, the third via hole 32 is arranged in a stepped manner, and the third via hole 32 includes a narrow hole section 321 through which the connection portion 312 can only pass and a wide hole section 322 in which the operation portion 311 can be accommodated; the opening depth of the wide hole section 322 is greater than the length of the operating portion 311, and a second avoidance space exists between the wide hole section 322 and the operating portion 311, so that a 'falling-in' structural foundation is provided at the second arm lever 3.
Preferably, in this embodiment, a first arc-shaped structure is formed on the outer circumferential surface of the operating portion 311 in a smooth transition manner, and a second arc-shaped structure is formed on the inner wall of the wide hole section 322 in a smooth transition manner corresponding to the first arc-shaped structure; thereby forming the second avoidance space between the first and second arcuate surface structures. Meanwhile, through the arrangement of the first arc-shaped structure and the second arc-shaped structure, the resistance between the operation part 311 and the wide hole section 322 during relative movement can be smaller, and the overall installation structure is simpler and more convenient.
In addition, the scheme is also provided with a first connecting rod 6 and a third pin shaft 61, and the first connecting rod 6 is rotatably arranged on the frame mounting plate 1 through the third pin shaft 61; the connecting portion 312 is disposed on the first connecting rod 6 after passing through the third via hole 32. In this structure, only the mounting hole for mounting the third pin 61 needs to be provided on the frame mounting plate 1, and the second arm 3 is hinged to the first connecting rod 6, so that when the second arm 3 is operated to fall down, its directly overturned force point will fall on the second pin 31, and the third pin 61 is mainly used as a hinge point to bear the rotation movement of the second arm 3 when opening and closing.
Furthermore, a second connecting rod 7 and a fan mounting plate 8 are further arranged in the scheme, one end of the second connecting rod 7 is hinged with the first arm rod 2, and the other end of the second connecting rod 7 is hinged with the fan mounting plate 8; the specific application principle of the fan mounting plate 8 can be referred to in the prior art, and is not described in detail herein.
In this embodiment, a first limit projection 22 is provided on the end portion of the first arm lever 2, and a second limit projection 71 is provided on the end portion of the second link 7, and the first limit projection 22 and the second limit projection 71 are overlapped in the vertical direction in the closed state. The fan mounting plate 8 is provided with a limiting clamping strip 81, and when the fan mounting plate is in a closed state, the limiting clamping strip 81 can move to abut against and contact with the first limiting bulge 22 and/or the second limiting bulge 71. Therefore, a sealing linkage mechanism of the hinge in a closed state is formed among the first limiting bulge 22, the second limiting bulge 71 and the limiting clamping strip 81, reliable window closing and sealing pressure supply are realized, and the use requirements of customers are met.
As a preferable scheme, in the present embodiment, the limiting clamping strip 81 is disposed on the end portion of the fan mounting plate 8 in a bending manner, so as to avoid the situation that the fan structural member needs to be designed to be avoided when the limiting clamping strip 81 is disposed on the side portion of the fan mounting plate 8.
Furthermore, in this embodiment, a frame fixing block 12 is further disposed corresponding to the frame mounting plate 1, and a mounting notch 121 for inserting the end of the frame mounting plate 1 is formed at the bottom of the frame fixing block 12, and the opening depth of the mounting notch 121 is adapted to the thickness of the frame mounting plate 1, so that the frame mounting plate 1 can be conveniently pushed into the lower portion of the frame fixing block 12. In actual hanging fan operation, when needs are connected hinge and casement frame, because the space is narrow and small, the screw on the casement frame is difficult to screw up, perhaps screws up and needs a long time, influences the operating efficiency. In the scheme, the mounting notch 121 is ingeniously arranged on the frame fixing block 12, so that the frame fixing block 12 can be mounted on a window frame in advance before a sash is hung, the sash is not blocked, the frame mounting plate 1 only needs to be pushed in place during sash hanging, the operation speed is higher, and the mounting efficiency can be effectively improved.
As a preferable scheme, in this embodiment, an inclined guide surface 13 and a limit bayonet 14 are provided at one end of the frame mounting plate 1 inserted into the mounting notch 121, and the inclined guide surface 13 may be designed to facilitate the insertion operation of the frame mounting plate 1 into the mounting notch 121.
The frame fixing block 12 is provided with a limiting post 122 corresponding to the limiting bayonet 14, so that the frame mounting plate 1 can be quickly positioned when inserted into the mounting notch 121, thereby improving the mounting efficiency. As a preferable scheme, in this embodiment, the position-limiting column 122 and the frame fixing block 12 are connected by a weak connection in a foldable manner, so that the position-limiting column 122 can be cut by the position-limiting bayonet 14 when the position of the frame mounting plate 1 is adjusted in the following step, and the operation is simple and convenient. In this embodiment, the mounting notches 121 and the limiting posts 122 are disposed on both sides of the frame fixing block 12, so that the frame fixing block 12 can be simultaneously applied to a left mullion structure and a right mullion structure.
In addition, the sash structural members in the present embodiment, such as the sash and the door leaf; and the specific structural form of the frame structural members, such as the window frame and the door frame, can be referred to in the prior art, and are not described herein in detail.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, so that any modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
