Description

Technical Field

[0001] This utility model relates to the field of environmental control technology for livestock sheds, specifically to a self-balancing air inlet window blade locking device. Background Technology

[0002] In enclosed poultry sheds, ventilation is a crucial method for environmental regulation. It regulates oxygen concentration, removes harmful gases, and adjusts negative pressure. As poultry grow, their daily requirements for suitable temperature, humidity, and ventilation vary. To meet these daily needs, the opening degree of ventilation windows varies, requiring timed intervals for fan operation. Therefore, in large-scale poultry shed environmental control, the degree of window opening needs to be automatically controlled based on ambient temperature, humidity, and negative pressure. When the temperature, humidity, and negative pressure are higher than set values, the ventilation window opening degree is increased; when they are lower than set values, the opening degree is decreased.

[0003] Currently, pig farms commonly use self-balancing ventilation windows on the side walls. These fans start under negative pressure, creating a pressure difference between the indoor and outdoor areas, causing the fan blades to automatically balance (open at a certain angle). Under the same pressure difference, the opening angle of the fan blades can be controlled by adjusting the counterweight. However, in winter, the demand for ventilation inside the shed decreases, and the self-balancing air inlets on the side walls need to be completely closed. Existing solutions mainly rely on adjusting the position of the counterweight (increasing the lever arm) to close the fan blades, but this method cannot reliably lock the blades, resulting in air leakage and causing cold stimulation to the pigs. Utility Model Content

[0004] To address the shortcomings of existing technologies, a self-balancing air inlet window blade locking device is proposed, which solves the problem in the aforementioned background technologies where reliable locking of the fan blades still occurs, resulting in air leakage.

[0005] To achieve the above objectives, the present invention proposes the following technologies: A self-balancing air inlet window blade locking device includes a locking buckle, which is rotatably mounted on the air inlet window frame. The locking buckle is provided with a pressing part for pressing the blade to achieve a seal between the blade and the frame. Rotating the locking buckle adjusts the relative position between the pressing part and the frame to lock or release the blade.

[0006] Furthermore, the locking buckle includes a main board that is rotatably connected to the frame, and the pressing part is specifically a pressing block disposed on one side of the main board. Rotating the main board causes the pressing block to abut against the fan blade to achieve locking.

[0007] Furthermore, two clamping blocks are symmetrically arranged on the main board, and a snap-fit ​​groove is formed between the two clamping plates. This allows the main board to be rotated and snapped into the frame through the snap-fit ​​groove when the fan blades are released, thereby realizing the storage and positioning of the clamping blocks.

[0008] Furthermore, the outer surfaces of the two clamping blocks are respectively inclined, and the inner edge of the clamping block is set as an arc transition surface to form a smooth rounded corner for easy rotation of the locking buckle.

[0009] Furthermore, it also includes a pivot mounted on the frame, the clamping block being located on one side of the motherboard, and an adapter hole being provided on the other side of the motherboard and fitted around the pivot through the adapter hole.

[0010] Furthermore, a limiting part is provided at one end of the rotating shaft, and a compression spring is provided between the limiting part and the main board. The compression spring is sleeved on the periphery of the rotating shaft, and compressing the compression spring causes the compression spring to generate thrust to drive the locking block to press against the fan blade.

[0011] Furthermore, it also includes a rivet nut riveted to the frame, the surface of the rotating shaft is provided with external threads, and the limiting part is specifically a flat knob, rotating the flat knob to drive the rotating shaft to be threadedly connected to the rivet nut.

[0012] Furthermore, the fan blade is located below the frame, and two locking buckles are symmetrically arranged on the frame. The two locking buckles abut and lock the fan blade from the left and right sides respectively. Multiple buckles are equidistantly arranged on the frame of the air inlet window.

[0013] Compared with the prior art, the comprehensive effects brought about by this utility model include: By setting a locking buckle and a pressing part on the locking buckle, rotating the locking buckle changes the position of the pressing part, thereby controlling the pressing part to abut against the fan blade to limit the fan blade. The fan blade is positioned by means of an external limiting structure, which solves the problem that the fan blade of the self-balancing air intake window cannot be closed tightly, improves the sealing performance, and avoids air leakage. In addition, the locking buckle can be rotated to release the pressing part from limiting the fan blade, so that the fan blade can be opened normally and achieve self-balancing air intake.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 7 As shown, a self-balancing air inlet window fan blade locking device includes a locking buckle 1, which is rotatably mounted on the air inlet window frame 2. The locking buckle 1 is provided with a pressing part for pressing the fan blade 3 to achieve a seal between the fan blade 3 and the frame 2. Rotating the locking buckle 1 adjusts the relative position between the pressing part and the frame 2 to lock or release the fan blade 3.

[0019] By setting the locking buckle 1 and the pressing part on the locking buckle 1, rotating the locking buckle 1 changes the position of the pressing part, thereby controlling the pressing part to abut against the fan blade 3 to limit the fan blade 3. The fan blade 3 is positioned by means of the external limiting structure, which solves the problem that the fan blade of the self-balancing air intake window cannot be closed tightly, improves the sealing performance, and avoids air leakage. In addition, the locking buckle 1 can be rotated to release the pressing part from limiting the fan blade 3, so that the fan blade 3 can be opened normally to achieve self-balancing air intake.

[0020] In the self-balancing air intake window blade locking device of this embodiment, the locking buckle 1 includes a main board 4 rotatably connected to the frame 2, and the pressing part is specifically a pressing block 5 disposed on one side of the main board 4. Rotating the main board 4 causes the pressing block 5 to abut against the fan blade 3 to achieve locking.

[0021] The main board 4, as the main body of the locking buckle 1, is rotatably connected to the frame 2, providing support for the clamping block 5, so that it can rotate on the frame 2 to drive the clamping block 5 connected to it to move closer to or away from the fan blade 3.

[0022] In the self-balancing air intake window blade locking device of this embodiment, two clamping blocks 5 are symmetrically arranged on the main board 4, and a snap-fit ​​groove 6 is formed between the two clamping plates 5. This facilitates the storage and positioning of the locking block 1 by rotating the main board 4 through the snap-fit ​​groove 6 and snapping it with the frame 2 when the fan blade 3 is released.

[0023] Two clamping blocks 5 are set to abut against the fan blade 3 to improve the limiting and locking effect. The clamping plate 5 protrudes from the main board 4, and the two clamping plates 5 and the main board 4 form a snap-fit ​​groove 6. When the fan blade 3 needs to be opened, the main board 4 is rotated to move the clamping plate 5 away from the fan blade 3. The main board 4 is parallel to the frame 2 and aligned with the snap-fit ​​groove 6 and the frame 2, so that the locking buckle 1 is snapped onto the frame 2, thereby preventing the locking buckle 1 from rotating at will and realizing the limiting and storage of the locking buckle 1.

[0024] Preferably, the distance between the two clamping blocks 5 matches the thickness of the frame 2.

[0025] The self-balancing air intake window blade locking device in this embodiment also includes a rotating shaft 8 disposed on the frame 2. The pressing block 5 is located on one side of the main board 4, and the other side of the main board 4 is provided with an adapter hole 9 and is sleeved around the rotating shaft 8 through the adapter hole 9.

[0026] The motherboard 4 is rotatably connected to the rotating shaft 8 through the adapter hole 9. The adapter hole 9 and the clamping block 5 are located at both ends, so that there is a certain gap between the clamping block 5 and the rotating shaft 8. Thus, after the clamping block 5 rotates, it can extend out of the frame 2 and contact the fan blade 3 to achieve clamping.

[0027] In the self-balancing air intake window blade locking device of this embodiment, a limiting part is provided at one end of the rotating shaft 8, and a compression spring 10 is provided between the limiting part and the main board 4. The compression spring 10 is sleeved on the periphery of the rotating shaft 8. Compressing the compression spring 10 causes the compression spring 10 to generate a thrust to drive the locking block 1 to press against the fan blade 3.

[0028] The spring 10 pushes the main board 4 downward. When the main board 4 drives the clamping block 5 to abut against the fan blade 3, the spring 10 pushes the clamping block 5 to press the fan blade 3 to achieve a locking effect. When it is necessary to open the fan blade 3, pull the main board 4 upward and rotate it so that the clamping block 5 passes above the frame 2 and aligns with the locking slot 6. Then, release the spring 10 and push it to engage the locking block 1 with the frame 2, thereby limiting and storing the locking block 1.

[0029] The self-balancing air intake window blade locking device in this embodiment also includes a rivet nut 11 riveted to the frame 2. The surface of the rotating shaft 8 is provided with an external thread. The limiting part is specifically a flat knob 12. Rotating the flat knob 12 drives the rotating shaft 8 to be threadedly connected to the rivet nut 11.

[0030] The above settings facilitate the installation of the shaft 8 and the frame 2. At the same time, by rotating the flat knob 12, the depth of the shaft 8 inserted into the rivet nut 11 and the frame 2 can be adjusted, thereby adjusting the compression degree of the compression spring 10 and changing the clamping force of the clamping block 5 on the fan blade 3. This makes it easier to adapt to different sealing requirements of the fan blade 3 and expand the scope of application.

[0031] In the self-balancing air inlet window blade locking device of this embodiment, the fan blade 3 is located below the frame 2, and two locking buckles 1 are symmetrically arranged on the frame 2. The two locking buckles 1 abut and lock the fan blade 3 from the left and right sides respectively. Multiple locking buckles are equidistantly arranged on the air inlet window frame 13 of the frame 2.

[0032] In the self-balancing air inlet window, the fan blade 3 is rotatably mounted on the frame 13 via the bottom rotating shaft. Its top is close to or away from the frame 2 to adjust the air intake. By setting two locking buckles 1 on the first frame 2, the fan blade 3 is locked from both sides to ensure that the fan blade 3 is closed and to improve the air leakage prevention effect.

[0033] In the self-balancing air intake window blade locking device of this embodiment, the outer surfaces of the two clamping blocks 5 are respectively inclined, and the inner edge of the clamping block 5 is set as an arc transition surface to form a smooth rounded corner 7 to facilitate the rotation of the locking buckle 1.

[0034] Specifically, the clamping block 5 converges away from the main board 4, designed with an inverted cone shape to optimize the feel and make it easier for users to pinch the locking buckle 1 to pull or rotate, requiring less effort. Rounded corners 7 are added to both sides of the entrance to the latching slot 6, allowing the edge of the clamping block 5 to smoothly transition with the frame 2 when the main board 4 is pulled and rotated, thus facilitating the adjustment of the locking buckle 1. Simultaneously, the rounded corners 7 guide the latching slot 6, facilitating the latching of the frame 2.
