[0001] The utility model relates to the technical field of curtain walls, and specifically, to a ventilation structure of a curtain wall. Background Art

[0002] A curtain wall is an exterior wall enclosure of a building and is a commonly used decorative wall for large and high-rise buildings. With the development of the construction market, door and window curtain walls are increasingly widely used, and some existing door and window curtain walls have a ventilation effect.

[0003] The existing patent application No. CN202122797243.0 discloses a door and window curtain wall with a ventilation switch structure, including a frame. The inner side walls of the frame are symmetrically provided with installation grooves, and toughened glass is arranged inside the installation grooves. The toughened glass is inserted into the frame. A control mechanism is arranged inside the frame, and a baffle is fixedly connected to one side of the surface of the control mechanism. The baffle slides on the side wall of the frame. In the utility model, when ventilation of the door and window curtain wall is required, the rotation of the rotating block drives the rotating rod to rotate, thereby driving the baffle to move up and down, facilitating quick opening and ensuring the ventilation effect of the door and window curtain wall, with strong practicality.

[0004] The above solution uses the rotation of the rotating block to drive the rotating rod to rotate, thereby driving the baffle to move upward to quickly open the baffle and ensure the ventilation effect of the door and window curtain wall. However, there are the following deficiencies in the implementation process. Since it is difficult to fix the rotating block and the gear after the baffle moves upward and opens, when the rotating block is released, the gravity of the baffle will drive the rack to move downward, resulting in the rotation of the gear and easily causing the baffle to cover the ventilation filter again. Therefore, a ventilation structure of the curtain wall is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a ventilation structure of a curtain wall to solve the problem in the prior art that it is difficult to fix the rotating block and the gear after the baffle moves upward and opens, resulting in the rotation of the gear when the rotating block is released due to the gravity of the baffle, and easily causing the baffle to cover the ventilation filter again.

[0006] The present utility model provides the following technical solutions: a ventilation structure for a curtain wall, including a frame. A drain opening is provided at the top side end of the frame. Tempered glass is installed at the top end of the frame. A filter screen for ventilation is fixedly connected to the side end of the frame. A baffle is installed at the side end of the frame close to the filter screen. A rack is fixedly connected to the side end of the baffle. A rotating mechanism for driving the rack to move up and down is provided between the side ends of the frame. A supporting mechanism for supporting the baffle is provided at the bottom end inside the frame. An installation groove is provided at the outer side end of the frame. Side grooves are spaced apart at the side end of the installation groove. A limiting mechanism for limiting the rotating mechanism is provided between the inner side end of the installation groove and the inner side end of the side groove.

[0007] As a preference of the above technical solution, the rotating mechanism includes a rotating rod. The rotating rod is rotatably arranged between the inner side end and the outer side end of the frame. A gear is fixedly connected to the outer end of the rotating rod. A knob is fixedly connected to the side end of the rotating rod. A plurality of jacks are provided at the side end of the knob. The gear meshes with the rack.

[0008] As a preference of the above technical solution, the limiting mechanism includes a fixing rod. The fixing rod is inserted between the inside of the installation groove and the inside of the side groove. A straight plate is fixedly connected to the side end of the fixing rod. A plug rod is fixedly connected to the side end of the straight plate. A pulling plate is fixedly connected to the side end of the fixing rod. A second spring is sleeved on the outer end of the fixing rod.

[0009] As a preference of the above technical solution, the straight plate is located inside the installation groove, and the pulling plate is located inside the side groove.

[0010] As a preference of the above technical solution, a chute is vertically provided at the inner side end of the frame. A slider is fixedly connected to the side end of the rack. The slider is slidably connected in the chute. A sleeve plate is fixedly connected to the side end of the baffle.

[0011] As a preference of the above technical solution, the supporting mechanism includes a round rod. The round rod is fixedly connected to the bottom end inside the frame. The round rod is inserted into the top end of the sleeve plate. A round plate is fixedly connected to the top end of the round rod. A first spring is sleeved on the outer end of the round rod.

[0012] As a preference of the above technical solution, the first spring is located at the bottom end of the sleeve plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The utility model is provided with a rotating mechanism. After rotating the knob, the rotating rod and the gear can be driven to rotate. At this time, the gear will engage with the rack, driving the rack to move up and down. The slider is slidably connected in the chute to limit the position of the rack, so that the rack can always engage with the side end of the gear. When the gear rotates to drive the rack and the baffle to move up, the sleeve plate will follow and move up. The spring I will rebound and push against the bottom end of the sleeve plate. At this time, after the baffle moves up, it no longer covers the ventilation filter screen. At this time, the baffle is opened, and the ventilation of the curtain wall can be realized through the filter screen. Through the setting of the supporting mechanism, the spring I always pushes against the bottom end of the sleeve plate to support the baffle, avoiding the baffle moving down easily due to gravity after moving up. Through the setting of the limiting mechanism, by adjusting the position of the fine-tuning knob, the jack on the side end of the knob is aligned with the position of the inserting rod. At this time, after releasing the pulling plate, the spring II will push the straight plate to rebound and drive the inserting rod to insert into the jack, thereby realizing the fixation of the position of the knob, making the knob unable to continue rotating, so that the rotating rod and the gear cannot rotate independently, so that the gear meshes with and supports the rack. Therefore, it is convenient to fix the knob and the gear, avoiding the problem that the baffle moves down after releasing the knob, and thus avoiding the baffle moving down after releasing the knob and covering the ventilation filter screen again.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0021] Such as Figures 1-4As shown in the figure, the present utility model provides a technical solution: a ventilation structure for a curtain wall, including a frame 1. A drain opening 101 is provided at the top side end of the frame 1. Tempered glass 102 is installed at the top end of the frame 1, which can quickly drain the water in the installation groove 105 of the tempered glass 102 to prevent the water from corroding the interior. A filter screen 103 for ventilation is fixedly connected to the side end of the frame 1. A baffle 202 for facilitating ventilation is installed at the side end of the frame 1 close to the filter screen 103. A rack 2 is fixedly connected to the side end of the baffle 202. A chute 104 is vertically opened at the side end of the interior of the frame 1. A slider 201 is fixedly connected to the side end of the rack 2, and the slider 201 is slidably connected in the chute 104. A sleeve plate 203 is fixedly connected to the side end of the baffle 202. A rotating mechanism for driving the rack 2 to move up and down is provided between the side ends of the frame 1. A supporting mechanism for supporting the baffle 202 is provided at the bottom end of the interior of the frame 1. An installation groove 105 is opened at the outer side end of the frame 1. Side grooves 106 are spacedly opened at the side end of the installation groove 105. A limiting mechanism for limiting the rotating mechanism is provided between the inner side end of the installation groove 105 and the inner side end of the side groove 106. The rotating mechanism can drive the baffle 202 to move up, and the baffle 202 can be opened. Ventilation is achieved through the filter screen 103. The supporting mechanism can support the baffle 202 after it moves up, preventing the baffle 202 from easily moving down due to gravity. Through the setting of the limiting mechanism, the rotating mechanism can be fixed, avoiding the problem that the baffle 202 moves down due to the rotation of the rotating mechanism.

[0022] Further, the supporting mechanism includes a round rod 3. The round rod 3 is fixedly connected to the bottom end of the interior of the frame 1. The round rod 3 is inserted into the top end of the sleeve plate 203. A round plate 301 is fixedly connected to the top end of the round rod 3. A first spring 302 is sleeved on the outer end of the round rod 3. The first spring 302 is located at the bottom end of the sleeve plate 203. In practice, the first spring 302 always abuts against the bottom end of the sleeve plate 203 to support the baffle 202, preventing the baffle 202 from easily moving down due to gravity after it moves up.

[0023] As an implementation manner in this embodiment, such as Figure 1 and Figure 2As shown in the figure, the rotating mechanism includes a rotating rod 4. The rotating rod 4 is rotatably arranged between the inner side end and the outer side end of the frame 1. A gear 401 is fixedly connected to the outer end of the rotating rod 4, and a knob 402 is fixedly connected to the side end of the rotating rod 4. A plurality of jacks 403 are formed in the side end of the knob 402. The gear 401 meshes with the rack 2. In practice, by rotating the knob 402, the rotating rod 4 and the gear 401 can be driven to rotate. At this time, the gear 401 will mesh with the rack 2, driving the rack 2 to move up and down. The slider 201 is slidably connected in the chute 104 to limit the position of the rack 2, so that the rack 2 can always mesh with the side end of the gear 401. When the gear 401 rotates to drive the rack 2 and the baffle 202 to move upward, the sleeve plate 203 will move upward accordingly. The first spring 302 will rebound against the bottom end of the sleeve plate 203. At this time, after the baffle 202 moves upward, it no longer covers the ventilation filter screen 103. At this time, the baffle 202 is opened, and the ventilation of the curtain wall can be facilitated through the filter screen 103.

[0024] As an implementation method in this embodiment, as Figure 4 shown, the limiting mechanism includes a fixed rod 5. The fixed rod 5 is inserted between the inside of the installation groove 105 and the inside of the side groove 106. A straight plate 501 is fixedly connected to the side end of the fixed rod 5, a plug rod 502 is fixedly connected to the side end of the straight plate 501, and a pulling plate 503 is fixedly connected to the side end of the fixed rod 5. A second spring 504 is sleeved on the outer end of the fixed rod 5. The straight plate 501 is located in the installation groove 105, and the pulling plate 503 is located in the side groove 106. In practice, by finely adjusting the position of the knob 402, the jack 403 on the side end of the knob 402 is aligned with the position of the plug rod 502. At this time, after releasing the pulling plate 503, the second spring 504 will rebound against the straight plate 501 and drive the plug rod 502 to insert into the jack 403, thereby fixing the position of the knob 402, so that the knob 402 cannot continue to rotate, so that the rotating rod 4 and the gear 401 cannot rotate independently, so that the gear 401 meshes with and supports the rack 2. Therefore, it is convenient to fix the knob 402 and the gear 401, avoiding the problem that the baffle 202 will move downward after releasing the knob 402, and thus avoiding the baffle 202 moving downward to cover the ventilation filter screen 103 again after releasing the knob 402.

[0025] Working principle: After pulling the pull plate 503, the pull plate 503 drives the fixed rod 5 to move towards the inside of the side groove 106. At this time, the straight plate 501 and the insertion rod 502 translate in the installation groove 105. At this time, the straight plate 501 will press against the second spring 504 and contract, and the insertion rod 502 will leave the jack 403. At this time, by rotating the knob 402, the rotating rod 4 and the gear 401 can be driven to rotate. At this time, the gear 401 will engage with the rack 2 and drive the rack 2 to move up and down. The slider 201 is slidably connected in the chute 104 to limit the position of the rack 2, so that the rack 2 can always engage with the side end of the gear 401. When the gear 401 rotates to drive the rack 2 and the baffle 202 to move up, at this time, the sleeve plate 203 also moves up, and the first spring 302 will rebound and push against the bottom end of the sleeve plate 203. At this time, after the baffle 202 moves up, it no longer covers the ventilation filter screen 103. At this time, the baffle 202 is opened, and the ventilation of the curtain wall can be realized through the filter screen 103. Since the first spring 302 always pushes against the bottom end of the sleeve plate 203, it can support the baffle 202 and prevent the baffle 202 from easily moving down due to gravity after moving up. At this time, in order to fix the position of the baffle 202, by adjusting the position of the fine-tuning knob 402, the jack 403 on the side end of the knob 402 is aligned with the position of the insertion rod 502. At this time, after releasing the pull plate 503, the second spring 504 will push the straight plate 501 to rebound and drive the insertion rod 502 to insert into the jack 403, thereby fixing the position of the knob 402 and making the knob 402 unable to continue rotating, so that the rotating rod 4 and the gear 401 cannot rotate independently, so that the gear 401 meshes with and supports the rack 2. Therefore, it is convenient to fix the knob 402 and the gear 401, avoiding the problem that the baffle 202 moves down after releasing the knob 402, and thus avoiding the baffle 202 moving down after releasing the knob 402 and covering the ventilation filter screen 103 again.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
