Description

Technical Field

[0001] This utility model relates to the field of swirl vent technology, and in particular to a hinged swirl vent. Background Technology

[0002] Swirl nozzles are commonly used air supply terminal devices in air conditioning systems. They organize airflow through unique internal swirl blades, inducing rapid mixing of surrounding air to form a high-flow-rate, high-induction-ratio attached jet. They are widely used for air supply in large spaces such as stadiums, exhibition halls, and industrial plants.

[0003] Swirl vents typically consist of an outer frame and swirl blade assemblies. The swirl blade assemblies are usually fixed inside the outer frame by welding or other methods, making them difficult to disassemble quickly. When the swirl blades are damaged or their performance degrades, maintenance personnel need to spend a lot of time and effort disassembling the rest of the vent to inspect or replace the blades. This not only increases maintenance costs but also causes prolonged equipment downtime, affecting production schedules. To address these issues, we propose a hinged swirl vent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hinged vortex air outlet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hinged swirl diffuser includes an outer frame, a support plate fixedly connected to the inner wall of the outer frame, and a hole opened inside the support plate. A connecting cylinder is inserted into the inner wall of the hole, and swirl blades are fixedly connected to the inner wall of the connecting cylinder. A connecting block is fixedly connected to the top of the connecting cylinder. Two sets of connecting plates are abutted to the upper side of the support plate, and a linkage block is fixedly connected to the side of the two sets of connecting plates that are close to each other. The other end of the linkage block is connected by a spring. A limit block is fixedly connected to the side of the connecting plate, and a positioning groove adapted to the limit block is opened inside the connecting block.

[0006] Preferably, the top of the outer frame is hinged to a door panel, and the door panel has through slots evenly distributed inside.

[0007] Preferably, there are two sets of connecting blocks, and the two sets of connecting blocks are connected to each other on the side closest to each other by a connecting rod.

[0008] Preferably, push bars are symmetrically connected to the outer side of the connecting cylinder, and a limiting groove is formed inside the support plate.

[0009] Preferably, a guide rod is fixedly connected to the inner wall of the outer frame, and the connecting plate has an insertion groove adapted to the guide rod inside.

[0010] Preferably, the linkage block is configured as a ring structure, and the inner wall of the linkage block is glued with a rubber sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with a connecting cylinder and a connecting block. During use, the connecting cylinder and the connecting block work together to facilitate the quick disassembly of the swirl blades for maintenance and replacement by the staff. This can be done without having to disassemble the entire outer frame, thus effectively improving the convenience of the device during maintenance.

[0012] 2. This device, equipped with a push bar and a limiting groove, enables rapid positioning of the connecting cylinder during installation through the cooperation of the push bar and the connecting rod. This allows the subsequent limiting block to be accurately inserted into the connecting block, and also limits the insertion depth of the connecting cylinder, preventing it from being excessively inserted into the support plate and affecting subsequent installation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4A hinged swirl air outlet includes an outer frame 1. A support plate 3 is fixedly connected to the inner wall of the outer frame 1. The support plate 3 has holes inside. A connecting cylinder 4 is inserted into the inner wall of the holes. Swirl blades 5 are fixedly connected to the inner wall of the connecting cylinder 4. A connecting block 6 is fixedly connected to the top of the connecting cylinder 4. Two sets of connecting plates 7 are abutted to the upper side of the support plate 3. A linkage block 8 is fixedly connected to the side of the two sets of connecting plates 7 that are close to each other. A certain gap is left between the connecting plate 7 and the inner wall of the outer frame 1, so as to meet the lateral movement requirements of the connecting plate 7. The other end of the linkage block 8 is connected by a spring 9. A limit block 10 is fixedly connected to the side of the connecting plate 7. A positioning groove adapted to the limit block 10 is opened inside the connecting block 6.

[0017] Furthermore, refer to Figure 2 It can be seen that the top of the outer frame 1 is hinged to the door panel 2, and the door panel 2 has evenly spaced through slots inside. The door panel 2 and the outer frame 1 are mainly connected by a door hinge, that is, a hinge in the prior art. The door hinge generally consists of two metal plates and a shaft connecting them. One metal plate is fixed to the edge of the outer frame 1 by screws or other fasteners, and the other plate is fixed to the edge of the door panel 2, so that the door panel 2 and the outer frame 1 can be movably connected to meet the opening and closing requirements of the door panel 2. The specific opening and closing principle will not be described in detail here. Through the through slots inside the door panel 2, debris can be blocked to achieve the filtering function. The support plate 3 is low in height, so when the door panel 2 is closed, there is still a certain gap between the bottom wall of the door panel 2 and the connecting block 6 and the connecting plate 7, so as not to affect the normal closing of the door panel 2.

[0018] Furthermore, refer to Figure 1 and Figure 2 It can be seen that there are two sets of connecting blocks 6, and the two sets of connecting blocks 6 are connected to each other on the side closest to each other by connecting rod 13. The setting of two sets of connecting blocks 6 can ensure the stability of the connecting cylinder 4 and the support plate 3 during installation. The connection of connecting rod 13 can facilitate the workers to quickly pull out the connecting cylinder 4 and the swirl blade 5 from the inside of the support plate 3, and can also facilitate the workers to pick up and transport the connecting cylinder 4.

[0019] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the outer side of the connecting cylinder 4 is symmetrically connected with push strips 12, and the inside of the support plate 3 is provided with a limiting groove 14. When the connecting cylinder 4 is installed in the hole provided inside the support plate 3, the push strips 12 connected to the side of the connecting cylinder 4 can be inserted into the limiting groove 14, so as to facilitate the precise docking between the subsequent limiting block 10 and the connecting block 6, and to limit the insertion depth of the connecting cylinder 4.

[0020] Furthermore, refer to Figure 3 It can be seen that the inner wall of the outer frame 1 is fixedly connected to the guide rod 11, and the inside of the connecting plate 7 is provided with a plug groove that matches the guide rod 11. When the connecting plate 7 moves laterally, the connecting plate 7 can be subjected to force and slide along the outer surface of the guide rod 11 to achieve lateral guidance of the connecting plate 7, thereby ensuring the stability of the connecting plate 7 when it moves.

[0021] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the linkage block 8 is set as a ring structure, and the inner wall of the linkage block 8 is glued with a rubber sleeve. Since the linkage block 8 is set as a ring, it is convenient for the staff to pull the two sets of linkage blocks 8 so that the forces are separated from each other, so that the two sets of limiting blocks 10 can be pushed out from the inside of the connecting block 6 at the same time, thereby effectively improving the convenience of disassembling the device. Through the glued rubber sleeve, it can effectively prevent the staff from being strangled when pulling the linkage block 8.

[0022] Working Principle: In use, the operator first installs the outer frame 1 in a suitable position. The swirling blades 5 inside the connecting cylinder 4 induce rapid mixing of the surrounding air. During maintenance, to remove the swirling blades 5, the operator first pulls the door panel 2 to rotate it, thus opening the opening of the outer frame 1. When the swirling blades 5 become deformed after prolonged use and need replacement, the operator manually pulls the linkage block 8 to move the two sets of connecting plates 7 away from each other, thereby pushing the limit block 10 out of the connecting block 6. Then, the operator can pull the connecting rod 13 to... Quickly remove the connecting cylinder 4 from the inside of the support plate 3. When installing a new set of swirl blades 5, the operator can first align the positions of the push bar 12 connected to the outside of the connecting cylinder 4 with the limiting groove 14. Then, the two sets of linkage blocks 8 can be pulled away from each other again, so that the push bar 12 can be embedded into the interior of each set of limiting grooves 14. At this time, the position of the limiting block 10 can be aligned with the position of the connecting block 6. When the operator stops pulling the linkage block 8, the limiting block 10 connected to the side of the connecting plate 7 can be reset by the elastic force of the spring 9 and embedded into the connecting block 6 for installation and fixation. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
