[0023] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] like Figure 1 and Figure 2As shown, a highly applicable, safety-equipped, limited-position ventilator includes a frame fixing base 5, a limiting transmission rod 1, and a pull rod 4. One end of the pull rod 4 is rotatably connected to the frame fixing base 5 via a rivet 6, and the other end of the pull rod 4 is rotatably connected to the limiting transmission rod 1 via a rivet 3. The rivet 6 is also provided with a connecting block 8, and a limiting mechanism 7 is provided between the connecting block 8 and the frame fixing base 5. The limiting transmission rod 1 is provided with a first U-shaped adjusting groove 10 for installing the rivet 3, and a slidable safety block 2 is also provided on the limiting transmission rod 1. The safety block 2 is provided with a second U-shaped adjusting groove 11, and the first U-shaped adjusting groove 10 and the second U-shaped adjusting groove 11 are closed or separated by the sliding of the safety block 2.

[0025] When opening the window sash, simply push the safety block 2 down to form a closed waist-hole structure between the second U-shaped adjusting slide 11 and the first U-shaped adjusting slide 10, allowing the window sash to be fixed at its maximum opening angle, thus achieving a limited ventilation effect. Pushing the safety block 2 up cancels the opening angle fixing function, allowing the window sash to open to its maximum, providing a better user experience. It breaks through the limitations of traditional limited ventilators, achieving the purpose of being both a limited ventilator and a transmission device, achieving a combined effect. Among them, a connecting block 8 is installed on the rivet 6, and a limiting mechanism 7 is installed between the connecting block 8 and the frame fixing seat 5. The frame fixing seat 5 can rotate along the connecting block 8, while the limiting mechanism 7 can relatively lock the connecting block 8 and the frame fixing seat 5 to prevent rotation when opening. This product also adds a safety function, so that the door and window can not only fix the limited ventilation and maximize the opening angle, but also connect with the transmission rod.

[0026] Further improvements include, for example Figure 3 As shown, the frame fixing seat 5 has a downward protruding stop block 13 on one side, and the bottom of the frame fixing seat 5 away from the stop block 13 has an arc-shaped bottom surface structure.

[0027] When the window sash is fixed, the downward-protruding stop block 13 on one side of the fixing seat can limit the pull rod 4, preventing the pull rod 4 from over-resetting. At the same time, the bottom of the frame fixing seat 5, away from the stop block 13, has an arc-shaped bottom surface structure. When the window sash is tilted open, the arc-shaped bottom surface can adapt to the tilt angle of the pull rod 4, thus making the combination of the frame fixing seat 5 and the pull rod 4 more compatible and avoiding the problem of bending and deformation of the pull rod 4 during operation.

[0028] A further improvement is made in that the frame fixing seat 5 is provided with a mounting groove 20, the connecting block 8 is fixed in the mounting groove 20 by the rivet 6, two limiting grooves 14 are symmetrically provided on the outer side of the connecting block 8, and two sets of limiting mechanisms 7 are provided in the mounting groove 20 to cooperate with and lock the limiting grooves 14.

[0029] Both limiting mechanisms 7 and connecting blocks 8 are fixed in the mounting groove 20 by rivets 6, which makes the two added limiting mechanisms 7 and connecting blocks 8 better concealed after installation and does not increase the overall thickness. The outer side of the connecting block 8 has two symmetrical limiting grooves 14, which can be locked and opened by the two limiting mechanisms 7. The stability is better when positioning the connecting block 8 and the frame fixing seat 5. When tilting is required, it can also be opened by rotation, which makes the window sash more adaptable to multiple states.

[0030] A further improvement is made to the limiting mechanism 7, which includes a spring 17 disposed in the mounting groove 20 and a steel column 16 pressed against the side wall of the connecting block 8 by the spring 17. The connecting block 8 is locked and limited by the steel columns 16 on both sides embedded in the limiting groove 14. The limiting groove 14 is also provided with an inner plastic part 15. The spring 17 and steel column 16 on both sides of the connecting block 8 are closed and hidden by the inner plastic part 15.

[0031] The steel column 16 is pressed against the connecting block 8 by the spring 17. When the steel column 16 is embedded in the limiting grooves 14 on both sides of the connecting block 8, the pull rod 4 and the frame fixing seat 5 are in a flush position. At this time, the pull rod 4 and the frame fixing seat 5 are in a locked and limited position, allowing the window sash to open normally without tilting. When the window sash needs to be tilted, the pull rod 4 and the frame fixing seat 5 can be rotated relative to each other by the pushing force. At this time, the steel column 16 is squeezed out of the limiting groove 14 by the rotation of the connecting block 8, thus facilitating the quick and large-angle opening of the window sash. There is an inner plastic part 15 inside the limiting groove 14. The springs 17 on both sides of the connecting block 8 and the steel column 16 can be closed and hidden by the inner plastic part 15. At the same time, the top of the steel column 16 can also be limited by the inner plastic part 15.

[0032] A further improvement is that the connecting block 8 has a square fixing hole 18 in the middle, the rivet 6 is fitted with a tower spring 19, and the bottom of the steel column 16 is supported and positioned by the tower spring 19.

[0033] The connecting block 8 has a square fixing hole 18 in the middle. The connecting block 8 is connected to the end of the rivet 6 through the square fixing hole 18, which enables the connecting block 8 and the rivet 6 to be relatively fixed without screws or other structures. This prevents the connecting block 8 and the rivet 6 from rotating relative to each other. A tower spring 19 is also fitted on the rivet 6. The bottom of the steel column 16 is supported and positioned by the tower spring 19, which allows the steel column 16 to change flexibly when it is engaged with the connecting block 8, and it is not easy to get stuck.

[0034] A further improvement is that a small plastic part 12 is provided at the bottom of the limiting transmission rod 1. The width of the small plastic part 12 is slightly larger than the width of the limiting transmission rod 1. The small plastic part 12 can make the window sash silent during opening and closing, avoiding the generation of friction noise.

[0035] A further improvement is that an elastic piece 9 is provided at the bottom of the first U-shaped adjusting slide 10, and the second rivet 3 located inside the first U-shaped adjusting slide 10 is limited by the elastic piece 9; the elastic piece 9 adopts a trapezoidal or arc-shaped structure, and one end of the elastic piece 9 is fixed to the bottom of the limiting transmission rod 1.

[0036] A trapezoidal or arc-shaped elastic plate 9 is installed at the bottom of the first U-shaped adjusting slide 10. When the window sash is opened, the second rivet 3 slides along the inner side of the first U-shaped adjusting slide 10 to the elastic plate 9, which will play a damping role, thereby reducing the impact force and preventing the user from being hit due to opening the window too fast. When the second rivet 3 enters the end of the first U-shaped adjusting slide 10 through the elastic plate 9, it can also play a limiting role, making the window sash more stable when opened to the maximum, and preventing the sliding problem caused by wind.

[0037] Further improvements include, for example Figure 4 As shown, the limiting transmission rod 1 is provided with an elongated through hole 24. The bottom of the through hole 24 is provided with an elastic pad 23 that is fixed to the bottom of the safety block 2 by a pin. The safety block 2 is clamped and fixed in the through hole 24 by the elastic pad 23. The safety block 2 can slide left and right along the through hole 24.

[0038] The combination of the safety block 2 and the elastic pad 23 enables the safety block 2 to slide within the through hole 24, thereby achieving the closure and separation of the first U-shaped adjusting groove 10 and the second U-shaped adjusting groove 11. The structure is simpler and the cost is lower. The elastic pad 23 has a certain elasticity, which makes it more convenient to clamp the safety block 2.

[0039] A further improvement is that the bottom of the through hole 24 is provided with an inwardly recessed groove 22, and the elastic pad 23 is provided with an upwardly curved and protruding retaining strip 21.

[0040] When the locking strip 21 on the pad is embedded in the groove 22 at the bottom of the through hole 24, the first U-shaped adjusting slide 10 and the second U-shaped adjusting slide 11 are in a separated state and have a certain limiting effect, which avoids the problem of insufficient opening distance between the first U-shaped adjusting slide 10 and the second U-shaped adjusting slide 11 and accidental sliding. When sliding, the user can clearly feel whether the position is in place. When it is fully opened, there will be a clear locking sound, which makes the user experience better.

[0041] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
