Description

Technical Field

[0001] This utility model relates to the field of metal flow equalization plate technology, and in particular to a stable metal flow equalization plate. Background Technology

[0002] Airflow equalization plates are used to connect different electrical components, such as transformers and circuit breakers, to ensure uniform airflow distribution throughout the system.

[0003] Chinese Patent Publication No. CN210486011U, published on 20200508, discloses an adjustable bidirectional flow equalization plate, including a baffle. An air outlet is provided in the middle of the baffle. A driving component and a fixing plate are respectively provided at the front end of the baffle. The fixing plate is fixedly connected to the front end of the baffle near the air outlet, and the driving component is located at the end of the fixing plate away from the air outlet. A movable through hole is provided in the middle of the fixing plate. A connecting shaft is provided on the inner wall of the movable through hole. The connecting shaft is rotatably connected to the inner wall of the movable through hole. A perforated plate is fixedly connected to the surface of the connecting shaft. The perforated plate is rotatably connected to the front end of the baffle.

[0004] Existing metal flow equalization plates, such as those mentioned above, can drive orifice plates to rotate via a coupling. The two couplings can rotate at different angles, allowing the shape of the two orifice plates to be adjusted as needed. This bidirectional adjustment of the angle between the two orifice plates enables scientific airflow guidance. However, in practice, the torsion bar, as the driving component of the orifice plate, lacks corresponding position constraint components on its outer side. This makes the torsion bar prone to abnormal deflection, affecting the overall stability of the metal flow equalization plate. Therefore, there is an urgent need to propose a corresponding metal flow equalization plate to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a stable metal flow equalization plate in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stable metal flow equalization plate includes a baffle, an orifice plate, and an adjustment assembly for adjusting the orifice plate. The adjustment assembly includes a drive box and a torsion bar. The drive box is fixedly connected to the outer wall of the baffle, and the outer wall of the drive box is rotatably connected to a swing sleeve via a rotating shaft. The inner and outer sides of the swing sleeve are respectively integrated with a pressure frame and an elastic component for maintaining the position of the pressure frame, and the pressure frame is pressed against the outer wall of the torsion bar.

[0008] Preferably, a series frame is fixedly connected to the outer wall of the drive box, and the series frame is fixedly connected to the outer wall of the baffle by a locking rod.

[0009] Preferably, the top of the pressure frame is integrally formed with a lifting ring, and the lifting ring has a U-shaped cross-section.

[0010] Preferably, a rubber pad is fixedly connected to the bottom of the pressure frame, and the rubber pad abuts against the outer wall of the torsion bar.

[0011] Preferably, the elastic component includes a slide plate fixedly connected to the outer wall of the pressure frame, the outer wall of the slide plate being slidably connected to the inner wall of the swing sleeve, and a spring being fixedly connected between the bottom of the slide plate and the inner wall of the swing sleeve.

[0012] Preferably, the slide plate has a rectangular cross-section and is integrally formed with the pressure frame.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, after the orifice plate is adjusted by the torsion bar, the pressure frame is pulled by the lifting ring. The pressure frame drives the sliding plate to slide against the inner wall of the swing sleeve, and the spring is stretched. Then, the pressure frame drives the swing sleeve to deflect until the pressure frame is placed above the torsion bar. At this time, the pressure frame is released, the spring pulls back the sliding plate, and the sliding plate drives the pressure frame to press against the outside of the torsion bar. The axial limit of the torsion bar is achieved by the contact friction between the pressure frame and the torsion bar. In this way, while retaining the orifice plate and its adjustment method, the overall stability of the metal flow equalization plate is ensured.

[0015] 2. In this application, the two sets of drive boxes are connected by a series frame. The series frame is fixed to the baffle by a locking rod, which ensures the stability of the drive box position and the convenience of disassembling and assembling the orifice plate and its corresponding adjustment structure, thereby improving the convenience of using the metal flow equalization plate.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A stable metal flow equalization plate includes a baffle 1, an orifice plate 6, and an adjustment assembly for adjusting the orifice plate 6. The adjustment assembly includes a drive box 2 and a torsion bar 3. The drive box 2 is fixedly connected to the outer wall of the baffle 1, and the outer wall of the drive box 2 is rotatably connected to a swing sleeve 8 via a rotating shaft. The inner and outer sides of the swing sleeve 8 are respectively integrated with a pressure frame 7 and an elastic component for maintaining the position of the pressure frame 7, and the pressure frame 7 is pressed against the outer wall of the torsion bar 3.

[0025] After adjusting the orifice plate 6 using the torsion bar 3, the pressure frame 7 is pulled by the lifting ring 9. The pressure frame 7 causes the sliding plate 11 to slide against the inner wall of the swing sleeve 8, stretching the spring 12. Then, the pressure frame 7 drives the swing sleeve 8 to deflect until the pressure frame 7 is positioned above the torsion bar 3. At this point, the pressure frame 7 is released, and the spring 12 pulls back the sliding plate 11. The sliding plate 11 causes the pressure frame 7 to press against the outside of the torsion bar 3. The axial limit of the torsion bar 3 is achieved through the contact friction between the pressure frame 7 and the torsion bar 3, thus ensuring the overall stability of the metal flow equalization plate while retaining the orifice plate 6 and its adjustment method.

[0026] It should be noted that the orifice plate 6 and its corresponding adjustment components are based on existing technology, and the specific structure of the adjustment components will not be described here.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, a series frame 4 is fixedly connected to the outer wall of the drive box 2. The series frame 4 is fixedly connected to the outer wall of the baffle 1 through a locking rod 5. The two sets of drive boxes 2 are connected through the series frame 4. The series frame 4 is fixed to the baffle 1 through the locking rod 5, which ensures the stability of the position of the drive box 2 and the convenience of disassembling and assembling the orifice plate 6 and its corresponding adjustment components, thereby improving the convenience of using the metal flow equalization plate.

[0028] Specifically, such as Figure 2 and Figure 3As shown, the top of the pressure frame 7 is integrally formed with a lifting ring 9, which has a U-shaped cross-section to facilitate the operator to lift the pressure frame 7. A rubber pad 10 is fixedly connected to the bottom of the pressure frame 7, and the rubber pad 10 abuts against the outer wall of the torsion bar 3 to ensure the stability of the contact between the pressure frame 7 and the torsion bar 3. The elastic component includes a sliding plate 11 fixedly connected to the outer wall of the pressure frame 7. The outer wall of the sliding plate 11 is slidably connected to the inner wall of the swing sleeve 8, and a spring 12 is fixedly connected between the bottom of the sliding plate 11 and the inner wall of the swing sleeve 8. When the pressure frame 7 is released, the spring 12 pulls back the sliding plate 11, and the sliding plate 11 drives the pressure frame 7 to press against the outside of the torsion bar 3. The axial limit of the torsion bar 3 is achieved through the contact friction between the pressure frame 7 and the torsion bar 3. The sliding plate 11 has a rectangular cross-section and is integrally formed with the pressure frame 7 to ensure the connection strength between the pressure frame 7 and the sliding plate 11.

[0029] Working principle: After the orifice plate 6 is adjusted by the torsion bar 3, the pressure frame 7 is pulled by the lifting ring 9. The pressure frame 7 drives the sliding plate 11 to slide against the inner wall of the swing sleeve 8, and the spring 12 is stretched. Then, the pressure frame 7 drives the swing sleeve 8 to deflect until the pressure frame 7 is above the torsion bar 3. At this time, the pressure frame 7 is released, and the spring 12 pulls back the sliding plate 11. The sliding plate 11 drives the pressure frame 7 to press against the outside of the torsion bar 3. The axial limit of the torsion bar 3 is achieved by the contact friction between the pressure frame 7 and the torsion bar 3. In this way, while retaining the orifice plate 6 and its adjustment method, the overall stability of the metal flow equalization plate is ensured. The two sets of drive boxes 2 are connected by a series frame 4. The series frame 4 is fixed to the baffle 1 by the locking rod 5. This ensures the stability of the position of the drive box 2 and the convenience of disassembling and assembling the orifice plate 6 and its corresponding adjustment components, thereby improving the convenience of using the metal flow equalization plate.
