It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0033] Embodiment:

[0034] As Figures 1-5 shown, in this embodiment, a milling-free casement window hinge limiting structure is provided, including a hinge assembly 1, a sash frame fixing plate 2, and a limiting device;

[0035] The hinge assembly 1 includes a stay fixing seat 11 and a stay rod 12. One end of the stay fixing seat 11 is hinged and slidably engaged with the sash frame fixing plate 2, and the other end is slidably engaged with the stay rod 12.

[0036] The limiting device includes a first limiting member 111 rotatably engaged with the stay fixing seat 11 and a second limiting member 121 provided on the stay rod 12;

[0037] The stay rod 12 has a clamping portion 122. When the stay rod 12 moves relative to the stay fixing seat 11, the first limiting member 111 abuts against the second limiting member 121 or the clamping portion 122.

[0038] For the problem that the existing milling-free hinge does not have a limiting structure, the structure of the first limiting member 111, the second limiting member 121, and the clamping portion 122 provided in the milling-free casement window hinge limiting structure of this embodiment can achieve the limiting effect. Specifically, it is achieved when the first limiting member 111 abuts against the clamping portion 122. At the same time, one end of the stay fixing seat 11 is hinged and slidably engaged with the sash frame fixing plate 2. By adjusting the position of one end of the stay fixing seat 11 on the sash frame fixing plate 2, the limiting angle can be adjusted to meet the usage scenarios of different door and window sizes.

[0039] The specific structures of the stay fixing seat 11 and the stay rod 12 in this embodiment are as follows:

[0040] The stay fixing seat 11 is provided with a first groove 112, and the stay rod 12 is provided with a second groove 123. The first groove 112 and the second groove 123 are arranged in communication. The first limiting member 111 is rotatably engaged in the first groove 112, the second limiting member 121 is arranged in the second groove 123, and the stay rod 12 is slidably engaged with the first groove 112.

[0041] At the same time, an opening 124 communicating with the second groove 123 is provided on the side surface of the stay rod 12, and one end of the opening 124 forms a clamping portion 122.

[0042] Specifically, a first limiting groove 1111 and a second limiting groove 1112 are respectively provided at two ends of the first limiting member 111. The specific structures of the first limiting groove 1111 and the second limiting groove 1112 are V-shaped groove structures. The first limiting groove 1111 or the second limiting groove 1112 can be abutted against the clamping portion 122.

[0043] In this embodiment, the specific structure of one end of the sliding support fixing seat 11 being hinged and slidably matched with the fan frame fixing plate 2 is as follows:

[0044] It further includes a slider seat 13. The slider seat 13 is slidably matched with the fan frame fixing plate 2. One end of the sliding support fixing seat 11 is hinged to the slider seat 13. Refer to Figure 6 , and the riveting connection is specifically realized by setting a rivet member. A fixing member 131 is provided on the slider seat 13. The fixing member 131 in this embodiment is specifically a screw member.

[0045] Specifically, a chute 21 is provided on the fan frame fixing plate 2. One end of the fixing member 131 passes through the chute 21. A pressing plate 132 and a gasket 133 are provided at one end of the fixing member 131.

[0046] When the limiting angle needs to be adjusted, loosen the fixing member 131 to make the fixing member 131 slide in the chute 21, so as to realize the sliding of the slider seat 13 relative to the fan frame fixing plate 2. After the adjustment structure is completed, fix the fixing member 131 with the pressing plate 132 and the gasket 133 and lock the fan frame fixing plate 2.

[0047] The specific structure of the hinge assembly 1 in this embodiment further includes a fan fixing plate 14, a long support arm 15, and a short support arm 16. The fan fixing plate 14 is respectively hinged to the sliding support rod 12, the long support arm 15, and the short support arm 16. The long support arm 15 and the short support arm 16 are hinged to the fan frame fixing plate 2.

[0048] Through the above-mentioned non-milling groove casement window hinge limiting structure, the limiting operation principle of the hinge assembly 1 is as follows:

[0049] In the default state, refer to Figure 3 , the hinge assembly 1 is in the closed state. The fan fixing plate 14, the long support arm 15, the short support arm 16, and the sliding support rod 12 are contracted into one body and are arranged in the same length extension direction as the fan frame fixing plate 2. At this time, the first limiting member 111 is in the second groove body 123. The length extension direction of the first limiting member 111 is the same as the length extension directions of the second groove body 123 and the fan frame fixing plate 2. The first limiting member 111 is in a separated state from the second limiting member 121 and the clamping portion 122;

[0050] Refer to Figure 4, when the hinge assembly 1 is in the open state, the stay fixed seat 11 rotates relative to the slider seat 13, and the stay rod 12 moves away from the stay fixed seat 11. At this time, the second limiting member 121 approaches and abuts against the second limiting groove 1112 of the first limiting member 111. The second limiting member 121 acts on the first limiting member 111 to rotate. At this time, the length extension direction of the first limiting member 111 is not consistent with the length extension direction of the second groove body 123. The second limiting member 121 causes one end of the first limiting groove 1111 of the first limiting member 111 to extend out from the opening 124. At the same time, because the second limiting groove 1112 is a V-shaped groove structure, the second limiting groove 1112 has a limiting effect on the first limiting member 111, and can limit the maximum distance that the stay rod 12 moves in the stay fixed seat 11. At this time, the fan fixing plate 14 is at the maximum opening angle relative to the fan frame fixing plate 2;

[0051] See Figure 5 , when the hinge assembly 1 is in the locked state, for example, the window sash connected to the fan fixing plate 14 is affected by wind pressure. At this time, the stay rod 12 moves closer to the stay fixed seat 11. Because one end of the first limiting groove 1111 of the first limiting member 111 extends out from the opening 124, when the stay rod 12 moves closer to the stay fixed seat 11, the clamping portion 122 abuts against the first limiting groove 1111. At the same time, the second limiting groove 1112 is separated from the second limiting member 121. The length extension direction of the first limiting member 111 is not consistent with the length extension direction of the second groove body 123. At this time, the first limiting member 111 restricts the stay rod 12 from continuing to move closer to the stay fixed seat 11, thus playing a locking role;

[0052] When the hinge assembly 1 needs to be returned to the default state, first act on the stay rod 12 to make the stay rod 12 move away from the stay fixed seat 11. At this time, the second limiting member 121 acts on the first limiting member 111 to rotate. Because the opening 124 is a clearance position, it will not restrict the rotation of the first limiting member 111. At the same time, the clamping portion 122 is separated from the clamping portion 122. When the length extension direction of the first limiting member 111 is consistent with the length extension directions of the second groove body 123 and the fan frame fixing plate 2, the locked state is released at this time. Then act on the stay rod 12 to make the stay rod 12 move closer to the stay fixed seat 11.

[0053] In summary, the structural design of the present application is reasonable. In view of the problem that the existing slotless hinge does not have a limiting structure, the structures of the first limiting member 111, the second limiting member 121 and the clamping portion 122 can achieve a limiting effect. At the same time, one end of the stay fixed seat 11 is hinged and slidably matched with the fan frame fixing plate 2, and the limiting angle can be adjusted to meet the usage scenarios of different door and window sizes, and the operation and adjustment are convenient and fast.

[0054] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the present utility model. Therefore, any modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the scope of the technical solution of the present utility model.
