[0001] This utility model belongs to the technical field of door and window connection structure, specifically relating to an anti-misalignment corner device. Background Technology

[0002] Corner brackets are typically installed at the corners of door and window sash profiles. Their two ends are connected to horizontal and vertical drive bars and other connecting parts by rivets, enabling the corresponding opening functions of doors and windows, such as outward opening, top-hung, inward opening, and tilt-and-turn.

[0003] See Figure 1 Existing corner brackets generally require components such as rotating shafts to connect and cooperate with the anti-misalignment rod and the corner bracket.

[0004] Meanwhile, the spring used in the rotating structure of the corner unit is a common linear torsion spring structure, which generally has a small elastic force. The elastic force is not strongly felt when rotating, resulting in poor operation feel. In addition, the structure of the linear torsion spring causes it to be misaligned vertically, so attention needs to be paid to the direction during installation, and there is also the problem of spring leakage.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0035] Unless otherwise defined, 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 pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Example:

[0037] like Figure 1-7 As shown, this embodiment provides an anti-misoperation corner device, including a corner frame 1, an adjustable corner device connecting rod 2, an anti-misoperation swing rod 3, and a U-shaped spring 4;

[0038] The anti-misswing rod 3 rotates and engages with the corner bracket 1 to form a placement cavity for placing the U-shaped spring piece 4. The placement cavity is provided with a barb part 303 that abuts against the U-shaped spring piece 4 and an inner groove 103 that engages with the end of the U-shaped spring piece 4.

[0039] The adjustable corner linkage 2 is slidably engaged with the corner frame 1, and the anti-missway rod 3 is located between the adjustable corner linkage 2 and the corner frame 1.

[0040] Compared to existing corner devices, the anti-misoperation corner device of this embodiment reduces the number of rotating shaft components. This is achieved by placing the anti-misoperation swing rod 3 between the adjustable corner device connecting rod 2 and the corner frame 1, and by using the structure of the adjustable corner device connecting rod 2 and the corner frame 1 to cooperate. This reduces the number of parts and thus reduces material costs. At the same time, the structure of the barb part 303 and the embedded groove 103 provided in the placement cavity can ensure that the U-shaped spring 4 is fully cooperated with the placement cavity, thereby reducing the problem of misoperation swing rod 3 swinging left and right.

[0041] Compared to the traditional linear torsion spring structure, the U-shaped spring 4 in this embodiment has a larger elastic force structure, and the anti-misalignment rod 3 has a better reset effect, ensuring the effect of repeated use.

[0042] The structure for the rotational engagement between the anti-misalignment rod 3 and the corner bracket 1 is as follows:

[0043] The corner frame 1 is provided with a connecting hole 101, and the anti-missway rod 3 is provided with a connecting post 301 that rotates and engages with the connecting hole 101. The connecting post 301 and the anti-missway rod 3 are integrally formed, which reduces the need for additional rotating shaft parts.

[0044] In this embodiment, the specific structure for placing the cavity is as follows:

[0045] The anti-misoperation swing rod 3 is provided with a U-shaped groove 302, and the corner frame 1 is provided with a mating groove 102. One end of the anti-misoperation swing rod 3 is located in the mating groove 102, and the U-shaped groove 302 and the mating groove 102 form a placement cavity.

[0046] Meanwhile, the specific structure of the U-shaped spring 4 is as follows:

[0047] It includes a spring mounting part 401 and a spring extension part 402. The spring mounting part 401 cooperates with the U-shaped groove 302, and the spring extension part 402 is located in the mating groove 102.

[0048] The barb portion 303 is located at the U-shaped groove 302, the inner groove 103 is located at the mating groove 102, the barb portion 303 abuts against the spring plate mounting portion 401, and the mating groove mates with the spring plate extension portion 402.

[0049] Specifically, there are two barbs 303, which are symmetrically arranged at both ends of the U-shaped groove 302, and two embedded grooves 103, which are symmetrically arranged on the groove wall surfaces on both sides of the mating groove 102.

[0050] Specifically, the end of the spring protrusion 402 is provided with a bent portion 403, which cooperates with the inner groove 103.

[0051] In the above structure, the spring mounting part 401 of the U-shaped spring 4 cooperates with the U-shaped groove 302, the barb part 303 abuts against the spring mounting part 401, and the bent part 403 of the spring extension part 402 of the U-shaped spring 4 cooperates with the inner groove 103. The above structure can effectively limit the overall position of the U-shaped spring 4 and reduce the problem of the left and right swing of the anti-misalignment rod 3.

[0052] See Figure 5 An clearance 104 is provided at the mating groove 102 of the corner frame 1. During the process of one end of the anti-misoperation swing rod 3 entering the mating groove 102, there is always a gap between the clearance and one end of the anti-misoperation swing rod 3, so as to facilitate the installation of the anti-misoperation swing rod 3.

[0053] In this embodiment, the adjustable angler connecting rod 2 is provided with a first boss 201, a second boss 202 and a third boss 203 in sequence along its length extension direction. The anti-missway rod 3 is provided with a limiting protrusion 304. The first boss 201 and the second boss 202 are in contact with the anti-missway rod 3, and the limiting protrusion 304 is located between the second boss 202 and the third boss 203.

[0054] In the above structure, see Figure 6 and 7 The limiting protrusion 304 limits the movement of the second protrusion 202 and the third protrusion 203 along the length of the adjustable corner linkage 2, thus fixing the adjustable corner linkage 2 to the corner frame 1. When the limiting protrusion 304 is outside the second protrusion 202 and the third protrusion 203, the limiting effect is released, and the adjustable corner linkage 2 can be moved and adjusted. During the movement and adjustment of the adjustable corner linkage 2, one or both of the first protrusion 201, the second protrusion 202, or the third protrusion 203 are always in contact with the end face of the anti-misalignment rod 3. For example... Figure 6 The first protrusion 201 and the second protrusion 202 are in contact with the end face of the anti-missway rod 3. Figure 7The third protrusion 2032 contacts the end face of the anti-misalignment rod 3. The above structure can prevent the anti-misalignment rod 3 from falling off the corner frame 1, reducing the additional cost caused by the need to use a riveting structure between the anti-misalignment rod 3 and the corner frame 1.

[0055] A damping block 5 is also provided on the adjustable corner linkage 2. The damping block 5 cooperates with the fan slot to prevent the corner linkage from swaying left and right in the fan slot and causing shaking. At the same time, it can effectively reduce the sound and reduce the generation of noise when the corner linkage moves in the fan slot.

[0056] An eccentric nail 7 is provided on the adjustable corner linkage 2, and a sleeve 6 is fitted on the eccentric nail 7. The eccentric nail 7 cooperates with the anti-mislocking seat assembly. The eccentric structure enables the door leaf sealing adjustment. At the same time, the sleeve 6 is provided to increase smoothness. The handle of the anti-mislocking seat assembly cooperates with the sleeve 6 to improve the feel of the handle when rotating.

[0057] In summary, compared with the existing corner device structure, the anti-misoperation corner device of this embodiment reduces the number of rotating shaft components, has a reasonable overall structural design, and is convenient for assembly and maintenance. At the same time, the structure of the barb part 303 and the embedded groove 103 can ensure that the U-shaped spring 4 fully cooperates with the placement cavity, thereby reducing the problem of misoperation of the anti-misoperation swing rod 3 swinging left and right.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
