[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a rack and pinion driven ventilator opening and closing mechanism.

[0020] Please see Figure 1 A rack and pinion driven ventilator opening and closing mechanism includes a bottom cover 1, an upper cover 2, a knob 3, a transmission gear 4, and a gear 5. The upper cover 2 is located above the bottom cover 1, the knob 3 is located above the upper cover 2, the transmission gear 4 is located between the bottom cover 1 and the upper cover 2, and the rack 41 on it meshes with the gear 5. The gear 5 is fixed to the knob 3 by a screw 6.

[0021] This utility model discloses a rack-and-pinion ventilator opening and closing mechanism, mainly comprising a bottom cover 1, an upper cover 2, a knob 3, a transmission gear 4, a gear 5, and a screw 6. The transmission gear 4 is disposed between the bottom cover 1 and the upper cover 2. A rack 41 is provided on one or both sides of the transmission gear 4, and the rack 41 meshes with the gear 5. The gear 5 is fixed to the knob 3 by the screw 6. When the knob 3 is rotated, the gear 5 rotates around the screw 6. During the rotation, the rack 41 also moves left and right, thereby driving the externally connected damper of the transmission gear 4 to open and close, realizing the opening and closing of the ventilator damper.

[0022] In a preferred embodiment, refer to Figure 1 The bottom cover 1 of the rack-driven ventilator opening and closing mechanism has grooves 11 on both sides, and a limiting ball 12 is provided in the groove 11. The outer side of the transmission gear 4 has an arc-shaped groove 42 that adapts to the front end of the limiting ball 12, and the inner side has a rack 41 that meshes with the gear 5. There are two sets of arc-shaped grooves 42, which are respectively set at the front and rear of the outer side of the transmission gear 4.

[0023] Specifically, the bottom cover 1 has grooves 11 on both sides inside for placing limiting balls 12. The limiting balls 12 are placed in the grooves 11 to limit the position of the transmission gear condition 4. Similarly, two sets of arc-shaped grooves 42 are provided on the outside of the transmission gear condition 4 to match the front end of the limiting balls 12. The two arc-shaped grooves 42 at the front limit the position of the ventilation door when it is open, and the two arc-shaped grooves 42 at the rear limit the position of the ventilation door when it is closed, so as to prevent the opening and closing mechanism from continuing to move left and right after opening or closing the ventilation door.

[0024] In a preferred embodiment, refer to Figure 1 The bottom cover 1 and top cover 2 of the rack-and-pinion ventilator opening and closing mechanism are both open structures. One end of the transmission gear 4 is exposed outside the opening and connected to the damper via a pin 7. The bottom cover 1 and top cover 2 are fixed by multiple fixing screws 8. By setting a pin 7 at the front end of the transmission gear 4 to connect with the damper of the ventilator, the flexible application of the opening and closing mechanism is ensured.

[0025] The rack and pinion driven ventilator opening and closing mechanism separates the knob 3 and gear 5 into two parts, ensuring that the parts can be replaced after damage, reducing costs, and making assembly convenient. The opening and closing mechanism can also be customized according to customer needs, changing the appearance, size and shape of the bottom cover 1, top cover 2 and knob 3 to meet the needs of different customers. By setting the opening and closing mechanism to a knob type, operation is more convenient and reliability is higher.

[0026] The rack and pinion driven ventilator opening and closing mechanism of this utility model has the following characteristics:

[0027] 1. Simple structure: By optimizing the design of the transmission mechanism, the overall structure is made simpler, making it easier to produce and maintain.

[0028] 2. Easy to operate: The knob handle makes it more convenient and faster for users to turn the ventilator on and off.

[0029] 3. High scalability: This transmission mechanism can be applied to different types of curtain wall ventilators, and has good versatility and compatibility.

[0030] 4. Enhanced user experience: The knob-style handle makes operation more convenient and improves user comfort; the limit ball on the bottom cover makes a sound when the product is fully opened or closed, enhancing the user experience.

[0031] 5. Enhanced market competitiveness: The transmission mechanism of this invention has high technical content and innovation, which can bring more competitive advantages to the product, enabling the product to stand out in the market, meet the needs of different users, and enhance the product's market competitiveness.

[0032] 6. Improve the stability of the transmission mechanism: By optimizing the structural design of the transmission mechanism, ensure that the transmission mechanism can still maintain stable operation under various severe weather conditions, and reduce the probability of failure.

[0033] 7. Reduced maintenance difficulty: By simplifying the structure of the transmission mechanism, maintenance personnel can more easily inspect, repair and replace parts, thereby reducing maintenance costs and time.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
