In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0043] See also Figures 1 to 16 In the specific embodiment shown, the utility model discloses a door and window anti-error device structure, including: a base 10, a rotating block 20, a limit shaft 30 and a reversing component 40. The limit shaft 30 passes through the base 10 and is connected to the rotating block 20 so that the rotating block 20 is rotatably connected to the base 10. The reversing component 40 is arranged in the base 10 and is connected to the rotating block 20. The reversing component 40 is operated to make the rotating block 20 reverse left and right along the base 10.

[0044] Specifically, a limiting shaft 30 passes through the base 10 and is connected to the rotating block 20. The reversing assembly 40 is connected to the rotating block 20. The reversing assembly 40 is operated to cause the rotating block 20 to reverse left and right along the base 10. This allows the anti-error device to be reversible, enabling the use of doors and windows with both left and right openings, improving adaptability and reducing costs. Furthermore, the left-right reversal of the anti-error device allows the same anti-error device to be used for both left-opening and right-opening windows. This means that the anti-error device can be installed in both left-opening and right-opening windows through its left-right reversal function, improving adaptability.

[0045] See also Figures 1 to 7 In the first embodiment shown, the reversing assembly 40 includes a reversing rod 41, a spring member 42 and a fixed shaft 43. A mounting hole 11 is provided on the side of the base 10. The fixed shaft 43 passes through the rotating block 20. One end of the reversing rod 41 is sleeved on the fixed shaft 43, and the other end extends out of the mounting hole 11. The spring member 42 is sleeved on the reversing rod 41. Rotating the reversing rod 41 causes the spring member 42 to squeeze and drive the fixed shaft 43 to rotate, so that the rotating block 20 is reversed left and right along the base 10.

[0046] Specifically, the anti-error device is installed on the transmission assembly, the direction of the tail end of the reversing rod 41 is determined according to the opening direction of the door and window, and the left and right reversal is achieved by toggling the tail end of the reversing rod 41.

[0047] Among them, when the door and window are opened to the left, the tail end of the reversing rod 41 and the rotating block 20 are both facing to the right, opposite to the opening direction of the door and window; when the door and window are opened, the fixed shaft 43 is squeezed to the right by the spring force to drive the rotating block 20 to rotate to the right, and at the same time drives the limit shaft 30 to rotate. When the rotating handle is operated incorrectly to drive the transmission rod, the bottom of the limit shaft 30 is against the notch on the transmission rod, thereby limiting the transmission of the transmission rod and realizing the function of preventing misoperation; when the door and window are closed, the rotating block 20 rotates to a vertical state under the pressure of the door frame to drive the limit shaft 30 vertically. At this time, the rotating handle locks the door and window, and the notch of the transmission rod can smoothly pass through the bottom of the limit shaft 30 to realize transmission locking.

[0048] Among them, when the door and window are opened to the right, the tail end of the reversing rod 41 and the rotating block 20 are both facing the left, which is opposite to the opening direction of the door and window; when the door and window are opened, the fixed shaft 43 is squeezed to the left by the spring force to drive the rotating block 20 to rotate to the left, thereby driving the limit shaft 30 to rotate. When the rotating handle is mistakenly operated to drive the transmission rod, the bottom of the limit shaft 30 is against the notch on the transmission rod, thereby limiting the transmission of the transmission rod and realizing the function of preventing misoperation; when the door and window are closed, the rotating block 20 rotates to a vertical state under the pressure of the door frame, driving the limit shaft 30 vertically. At this time, the rotating handle locks the door and window, and the notch of the transmission rod can smoothly pass through the bottom of the limit shaft 30 to realize transmission locking.

[0049] See also Figures 1 to 3As shown, in one embodiment, a fixed block 50 is further provided between the rotating block 20 and the base 10, and the fixed block 50 is provided with a limiting groove 51. The fixed shaft 43 passes through the rotating block 20, the limiting groove 51 and the reversing rod 41 from top to bottom in sequence, and the midpoint of the limiting groove 51 and the two ends have a preset height difference.

[0050] Specifically, the limiting shaft 30 passes through the base 10, the fixed block 50 and the rotating block 20 in sequence and is riveted and connected; the fixed shaft 43 passes through the rotating block 20, the fixed block 50 and the reversing rod 41 in sequence for reversing linkage. Among them, the limiting groove 51 is used to install the fixed shaft 43 and limit the trajectory of position changes during use, which helps to maintain the stability and accuracy of the entire reversing assembly 40 and prevent inaccurate reversing or failure caused by the position offset of the fixed shaft 43. Among them, the midpoint and the two ends of the limiting groove 51 have a preset height difference (for example: 1-3mm), which is convenient for limiting the trajectory of the position change of the fixed shaft 43 during use. The limiting groove 51 can be arc-shaped or triangular.

[0051] See also Figures 1 to 3 As shown, in one embodiment, the fixing block 50 is provided with a blocking piece 52 , which is located outside the mounting hole 11 to block the end of the reversing rod 41 protruding from the mounting hole 11 from the front.

[0052] Specifically, the baffle 52 is used to avoid reversing the reversing rod 41 and prevent the reversing rod 41 from accidentally reversing. In other words, when the reversing rod 41 needs to rotate to change the direction of the rotating block 20, the baffle 52 can ensure that the reversing rod 41 does not interfere with or collide with the mounting hole 11 or other components, thereby protecting the integrity and function of the reversing assembly 40. In addition, the baffle 52 also plays a role in preventing the reversing rod 41 from accidentally reversing. During daily use, various factors (such as accidental touch, wind force, etc.) may cause the reversing rod 41 to rotate unnecessarily. The design of the baffle 52 can effectively prevent such accidental touches from occurring, ensuring that the reversing operation only occurs when the user actively initiates it.

[0053] In one embodiment, at least one punch bridge 53 is further provided on the side of the fixing block 50 , and a protrusion 12 corresponding to the punch bridge 53 is provided on the side wall of the base 10 , and the punch bridge 53 is engaged with the protrusion 12 .

[0054] Specifically, the punch bridge member 53 cooperates with the raised portion 12 on the side wall of the base 10 to provide an additional fixing point between the fixed block 50 and the base 10. This design can significantly enhance the stability of the entire anti-error device structure and prevent loosening or deformation caused by uneven force or external impact during use. In addition, the cooperation between the raised portion 12 and the punch bridge member 53 also acts as a limiter, limiting the range of movement of the fixed block 50 on the base 10, which helps maintain the accuracy and stability of the entire reversing assembly 40 and ensures the accuracy and reliability of the reversing operation. In addition, the design of the raised portion 12 provides a clear installation position for the punch bridge member 53, allowing the fixed block 50 to be quickly and accurately positioned during installation, which helps improve installation accuracy and reduce performance issues caused by inaccurate installation positions. In addition, the cooperation between the punch bridge member 53 and the raised portion 12 makes the installation process simpler and faster. The punch bridge member 53 only needs to be aligned with the raised portion 12 for installation, without the need for complex adjustment and calibration. In addition, the close fit between the punch bridge 53 and the raised position 12 can reduce the friction and wear caused by loose components, thereby extending the service life of the entire anti-error device structure. This design can also enhance the ability of the anti-error device structure to resist external forces such as wind and vibration, ensuring its stability and reliability in harsh environments.

[0055] Preferably, the number of the punching bridge pieces 53 is four, with two being distributed on each side of the fixing block 50 , so that the connection between the fixing block 50 and the base 10 is firm and not easy to fall off.

[0056] In one embodiment, the bottom of the fixing shaft 43 abuts against the base 10 .

[0057] Specifically, the close contact between the bottom of the fixed shaft 43 and the base 10 forms a stable support point, which effectively prevents the reversing rod 41 from falling off the fixed shaft 43 due to uneven force, vibration or misoperation during use. This design ensures the overall stability of the reversing assembly 40 and extends the service life of the product. In addition, if the reversing rod 41 falls off, it will not only affect the normal use of doors and windows, but may also cause damage to users or surrounding objects, posing a safety hazard. The design of the bottom of the fixed shaft 43 abutting against the base 10 fundamentally eliminates this risk and improves the safety of the product. In addition, the stable connection of the reversing rod 41 is the basis for ensuring the accuracy of the reversing operation. If the reversing rod 41 becomes loose or falls off, it will directly affect the accuracy and reliability of the reversing. The abutment between the fixed shaft 43 and the base 10 ensures the stability of the reversing rod 41 during operation, thereby ensuring the accuracy of the reversing.

[0058] See also Figures 8 to 12In the second embodiment shown, the reversing assembly 40 includes a rotating member 44, a connecting ring 45 and a U-shaped spring piece 46. The U-shaped spring piece 46 is mounted on the base 10. The rotating member 44 passes through the rotating block 20 and is connected to the connecting ring 45. The connecting ring 45 is provided with a boss 451, and the boss 451 cooperates with the U-shaped spring piece 46. The rotating member 44 is adjusted so that the connecting ring 45 abuts the first side or the second side of the U-shaped spring piece 46, so that the rotating block 20 can be reversed left and right along the base 10.

[0059] Specifically, the anti-error device is mounted on the transmission assembly. Left-right direction switching is achieved by adjusting the rotating member 44 to rotate the connecting ring 45 to the corresponding position. The base 10 is provided with a slot for mounting a U-shaped spring clip 46. The limit shaft 30 passes through the base 10 and the rotating block 20 and is riveted together. The rotating member 44 passes through the rotating block 20 and the connecting ring 45 and is riveted together, providing direction control and linkage.

[0060] Among them, a U-shaped spring piece 46 is installed on the base 10, and the rotating block 20 is riveted together by the limit shaft 30. When the door or window is opened to the left, the boss 451 of the connecting ring 45 is on the right side of the base 10, and the rotating block 20 faces to the right. When the transmission rod is transmitted, the bottom of the limit shaft 30 will abut against the corresponding notch on the transmission rod, so that it cannot be transmitted; when the door or window is closed, the boss 451 squeezes the U-shaped spring piece 46, so that the rotating block 20 rotates to a vertical state, and the bottom of the limit shaft 30 will smoothly pass through the corresponding notch on the transmission rod to realize transmission, that is, realize the anti-misoperation function.

[0061] In one embodiment, the connecting ring 45 is provided with a first limiting point and a second limiting point on both sides of the protruding column 451 , and the rotating block 20 is provided with a locking column 21 corresponding to the first limiting point and the second limiting point.

[0062] Specifically, when the anti-misoperation device is to be opened to the left and needs to be reversed, the rotating member 44 is adjusted to drive the connecting ring 45 to rotate counterclockwise so that the boss 451 squeezes the U-shaped spring piece 46. When the boss 451 passes over the tail end of the U-shaped spring piece 46, the U-shaped spring piece 46 rebounds, and the boss 451 and the rotating block 20 are further adjusted to be vertical. At this time, the boss 451 can pass over the tail end of the U-shaped spring piece 46 without interference. The rotating block 20 is dialed to the right to the maximum angle position, and the second limit point is adjusted to the locking post 21. At this time, the boss 451 passes over the U-shaped spring piece 46 to achieve reversal, thereby realizing the anti-misoperation function. When the anti-misoperation device is to be opened to the right and needs to be reversed, the rotating member 44 is adjusted to drive the connecting ring 45 to rotate clockwise so that the boss 451 squeezes the U-shaped spring piece 46. When the boss 451 passes over the tail end of the U-shaped spring piece 46, the U-shaped spring piece 46 rebounds, and the boss 451 and the rotating block 20 are further adjusted to be vertical. At this time, the boss 451 can pass over the tail end of the U-shaped spring piece 46 without interference. The rotating block 20 is dialed to the left to the maximum angle position, and the first limit point is adjusted to the locking column 21. At this time, the boss 451 passes over the U-shaped spring piece 46 to achieve reversal, and the anti-misoperation function in the other direction can be achieved.

[0063] Preferably, the rotating member 44 is a rivet, which has high structural strength and low cost.

[0064] See also Figures 13 to 16 In the third embodiment shown, the reversing assembly 40 includes a screw 47 and a curved spring piece 48. The curved spring piece 48 is installed on the base 10. The screw 47 passes through the rotating block 20 and abuts against the side of the curved spring piece 48. The screw 47 is adjusted so that the screw 47 abuts against the first side or the second side of the curved spring piece 48, so that the rotating block 20 reverses left and right along the base 10.

[0065] Specifically, the anti-error device is mounted on the transmission assembly, and left-right reversal is achieved by adjusting the tightness of screw 47. The base 10 is provided with a slot for mounting a curved spring 48. The limiting shaft 30 passes through the base 10 and the rotating block 20 and is riveted together. Screw 47 is fixed to the rotating block 20 to compress the curved spring 48 and reverse the direction.

[0066] A curved spring piece 48 is mounted on the base 10, and the rotating block 20 is riveted together via the limiting shaft 30. When the door or window is opened to the left, the anti-error device rotating block 20 faces right. When the transmission rod is actuated, the bottom of the limiting shaft 30 abuts against the corresponding notch on the transmission rod, preventing transmission. When the door or window is closed, the bottom of the screw 47 squeezes the curved spring piece 48, causing the rotating block 20 to rotate to a vertical position. The bottom of the limiting shaft 30 smoothly passes through the corresponding notch on the transmission rod, enabling transmission and realizing the anti-error operation function. In addition, when the anti-error device needs to be reversed to the left, the screw 47 is adjusted to a loose state. After adjusting until the bottom of the screw 47 can directly cross the curved spring piece 48, the rotating block 20 is moved to the left to the maximum angle position, and the screw 47 is adjusted to a locked state. At this time, the bottom of the screw 47 and the curved spring piece 48 are in contact with each other, and the anti-error operation function can be achieved; when the anti-error device needs to be reversed to the right, the screw 47 is adjusted to a loose state. After adjusting until the bottom of the screw 47 can directly cross the curved spring piece 48, the rotating block 20 is moved to the right to the maximum angle position, and the screw 47 is adjusted to a locked state. At this time, the bottom of the screw 47 and the curved spring piece 48 are in contact with each other, and the anti-error operation function in the other direction can be achieved.

[0067] See also Figure 2 、 Figure 9 and Figure 14 As shown, a limiting protrusion 31 is further provided at the bottom of the limiting shaft 30 .

[0068] Specifically, when the rotating block 20 rotates to a vertical position, the stop protrusion 31 smoothly passes through the notch in the transmission rod. This effectively sets a clear initial position or working position for the transmission rod or the entire mechanism. Once this position is reached, the cooperation between the stop protrusion 31 and the notch serves as a positioning function, ensuring that the mechanism can accurately stay in the predetermined position. Furthermore, when the transmission rod needs to begin transmission or is in the transmission state, the stop protrusion 31 will abut the corresponding notch in the transmission rod, thereby preventing further movement of the transmission rod or changing its motion state. This design effectively prevents the transmission rod from moving when not needed, avoiding mechanical failure, damage, or safety accidents caused by unintended movement.

[0069] See also Figure 1 、 Figure 8 and Figure 13 As shown, an eccentric adjustable sleeve assembly 60 is further connected to one end of the rotating block 20 away from the reversing assembly 40 .

[0070] Specifically, the eccentric adjustable sleeve assembly 60 includes an eccentric shaft 61 and a sleeve 62. The eccentric shaft 61 is riveted and mounted on the rotating block 20 via the sleeve 62. Due to installation deviation and other reasons, the door and window may fall off. Adjusting the eccentric shaft 61 can prevent it from sinking. The sleeve 62 contacts the lock seat on the frame to provide an upward support force.

[0071] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
