[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0036] Embodiment:

[0037] As Figures 1-5 shown, in this embodiment, an anti-misoperation angle adjuster is provided, which includes an angle frame 1, an adjustable angle adjuster connecting rod 2, an anti-sway rod 3 and a U-shaped elastic sheet 4;

[0038] The anti-sway rod 3 is rotationally matched with the angle frame 1. The U-shaped elastic sheet 4 is arranged on the anti-sway rod 3. The U-shaped elastic sheet 4 includes a mounting portion 401 and an extending portion 402. The mounting portion 401 is arranged close to the swing center line 307 of the anti-sway rod 3, and the extending portion 402 extends in a direction away from the swing center line 307 of the anti-sway rod 3. The extending portion 402 of the U-shaped elastic sheet 4 abuts against the angle frame 1;

[0039] The anti-sway rod 3 is further provided with a blocking portion 306. During the process of the anti-sway rod 3 swinging relative to the angle frame 1 under an external force, the blocking portion 306 contacts and drives the extending portion 402 to swing. When the state of the anti-sway rod 3 being under an external force is released, the extending portion 402 pushes the blocking portion 306 to reset. The above external force comes from the pushing force of the lock seat when closing the window, and this is hereby explained.

[0040] The anti-sway rod 3 is provided with a first limit protrusion 305;

[0041] The adjustable angle adjuster connecting rod 2 is slidably matched with the angle frame 1, and the adjustable angle adjuster connecting rod 2 is provided with a limiting portion;

[0042] During the process of the anti-sway rod 3 rotating relative to the angle frame 1, the first limit protrusion 305 is engaged with or separated from the limiting portion.

[0043] The rotation structure in the anti-misoperation angle adjuster of this embodiment is provided with a U-shaped elastic sheet 4. Compared with the traditional linear torsion spring structure, the elastic effect structure of the U-shaped elastic sheet 4 is larger, and the reset effect of the anti-sway rod 3 is better, ensuring the effect of cyclic use. At the same time, according to the position of the anti-sway rod 3 rotating relative to the angle frame 1, the first limit protrusion 305 and the limiting portion are brought into a state of being engaged or separated: when the first limit protrusion 305 is in a state of being engaged with the limiting portion, the relative fixed connection between the adjustable angle adjuster connecting rod 2 and the angle frame 1 is realized, preventing the movement of the adjustable angle adjuster connecting rod 2. When the first limit protrusion 305 is in a state of being separated from the limiting portion, the relative fixed contact between the adjustable angle adjuster connecting rod 2 and the angle frame 1 is realized, and the adjustable angle adjuster connecting rod 2 can be adjusted for movement.

[0044] The specific structure of the anti-sway rod 3 in this embodiment is as follows:

[0045] It includes an anti-mistaken swing part 301 and a swing rod part 302. The anti-mistaken swing part 301 is a circular structure. The anti-mistaken swing part 301 is provided with a first groove 303 for placing the U-shaped spring piece 4. The corner frame 1 is provided with a first matching groove 101 and a second matching groove 102. The anti-mistaken swing part 301 is rotatably matched with the first matching groove 101, and the protruding part 402 of the U-shaped spring piece 4 is in contact with the inner wall surface of the second matching groove 102.

[0046] The first groove 303 is used to place the U-shaped spring piece 4, which plays a protective role on the U-shaped spring piece 4 and reduces the jamming phenomenon caused by the structural damage of the U-shaped spring piece 4. In the above structure, the first matching groove 101 can ensure that the anti-error swing part 301 rotates and swings. In the process of applying force to make the anti-error swing rod 3 rotate and swing, the specific situation is that when the anti-error lock seat assembly collides with the anti-error swing rod 3, the force of one end of the U-shaped spring piece 4 abutting against the inner wall surface of the second matching groove 102 increases. At this time, the compression force of the U-shaped spring piece 4 increases. When the force is applied to the anti-error swing rod 3, the state of the U-shaped spring piece 4 is restored, so that the anti-error swing rod 3 is restored and reset to the initial position.

[0047] This embodiment further includes a rotating shaft 5, and the anti-mistaken swing part 301 of the anti-mistaken swing rod 3 is rotatably matched with the corner frame 1 through the rotating shaft 5. The rotating shaft 5 can prevent the anti-mistaken swing part 301 from shaking when rotating in the first matching groove 101, and ensure that the anti-mistaken swing part 301 swings in the axial direction of the rotating shaft 5. At the same time, the rotating shaft 5 and the anti-mistaken swing part 301 are combined to cover the first groove 303, which can further protect the U-shaped spring piece 4 and reduce the jamming phenomenon caused by the structural damage of the U-shaped spring piece 4.

[0048] The corner frame 1 of this embodiment is provided with an arc-shaped guide edge portion 103, and the swing arm portion 302 is provided with an arc-shaped guide groove 304 that matches the arc-shaped guide edge portion 103. The above structure can ensure the stability of the anti-mistake swing arm 3 during the swinging process.

[0049] In this embodiment, the specific structure of the first limiting protrusion 305 cooperating with or separating from the limiting portion is as follows:

[0050] The first limiting protrusion 305 is provided on the swing rod portion 302, and the adjustable angler connecting rod 2 is provided with two second limiting protrusions 201, and the two second limiting protrusions 201 form a limiting portion. When the first limiting protrusion 305 is between the two second limiting protrusions 201, the first limiting protrusion 305 and the limiting portion are in a matching state.

[0051] Two of the second limiting protrusions 201 are arranged along the length direction of the adjustable swivel link 2. When the first limiting protrusion 305 is between the two second limiting protrusions 201, the first limiting protrusion 305 limits the movement of the two second limiting protrusions 201 in the length direction of the adjustable swivel link 2, so that the adjustable swivel link 2 is fixedly connected to the swivel bracket 1 relatively. When the first limiting protrusion 305 is outside the two second limiting protrusions 201, the limiting effect is released, and at this time, the adjustable swivel link 2 can be adjusted by moving.

[0052] In order to increase the stability of the overall installation, a swivel locator 6 is provided on the adjustable swivel link 2. The swivel locator 6 is provided with a mating portion that cooperates with the second limiting protrusion 201. A limiting portion is formed between the two mating portions. The swivel locator 6 is provided with a positioning protrusion 601, and the positioning protrusion 601 is arranged close to the swing rod portion 302. After the adjustable swivel link 2 is connected to the swivel bracket 1, the positioning protrusion 601 of the swivel locator 6 positions the anti-misalignment swing rod 3, ensuring that the first limiting protrusion 305 of the anti-misalignment swing rod 3 is within the limiting portion. If the positioning protrusion 601 interferes with the anti-misalignment swing rod 3, the adjustable swivel link 2 needs to be adjusted.

[0053] The above-mentioned swivel locator 6 is made of plastic material.

[0054] This embodiment further includes a swivel spring piece 9. The swivel spring piece 9 cooperates with the swivel bracket 1, and both ends of the swivel spring piece 9 are respectively connected to the swivel bracket 1 and the adjustable swivel link 2. The swivel spring piece 9 can increase the damping feeling during the relative movement of the adjustable swivel link 2 relative to the swivel bracket 1, ensuring the stability of the relative movement.

[0055] An eccentric nail member 7 is provided on the adjustable swivel link 2 of this embodiment, and a sleeve 8 is sleeved on the eccentric nail member 7. The eccentric nail member 7 cooperates with the anti-misalignment lock seat assembly. Through the eccentric structure, the sealing of the door leaf can be adjusted. At the same time, the provided sleeve 8 is to increase the smoothness, and the handle of the anti-misalignment lock seat assembly cooperates with the sleeve 8 to improve the feel when the handle rotates.

[0056] In summary, the rotating structure in the anti-misalignment swivel of this embodiment is provided with a U-shaped spring piece 4. Compared with the traditional linear torsion spring structure, the elastic effect structure of the U-shaped spring piece 4 is larger, the reset effect of the anti-misalignment swing rod 3 is better, ensuring the effect of cyclic use. At the same time, the provided limiting structure can adjust the movement of the adjustable swivel link 2. The overall structure is reasonably designed, facilitating assembly and maintenance.

[0057] 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.
