Description

Technical Field

[0001] This utility model belongs to the field of ventilation and fire damper technology, and in particular relates to a ventilation and fire damper blade mounting support frame. Background Technology

[0002] Fire dampers are temperature-controlled valves made of shape memory alloy. They are closed by gravity and spring mechanism. When the smoke temperature reaches 280℃, people have basically evacuated, and smoke exhaust is no longer practical. At this point, the smoke is already on fire, so the valve automatically closes to prevent the fire from spreading.

[0003] When installing a fire damper, the blades need to be connected to the damper housing to form the damper. During connection, the blade support rods need to be inserted into the mounting points on the housing. However, multiple blade support rods need to be inserted from one side of the fire damper housing to the other, requiring the installer to constantly rotate the housing. Therefore, we need to design a ventilation fire damper blade mounting support frame with a rotating support platform to support the fire damper housing. The rotating platform drives the fire damper housing to rotate, allowing the installer to accurately align the blade support rods with the mounting points on the housing. The rotating platform, which in turn rotates the housing during installation, allows for fine-tuning of the blade angle at any time during installation, facilitating convenient operation and shortening installation time. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation fire damper blade installation support frame, which has a structure that uses a rotating support platform to support the outer shell of the fire damper. The rotating platform drives the fire damper outer shell to rotate, allowing the installer to more accurately align the blade support rod with the installation point on the fire damper outer shell. During installation, the rotating platform drives the fire damper outer shell to rotate, and the blade angle can be finely adjusted at any time during the installation process. This convenient operation through the rotating platform shortens the installation time and solves the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A ventilation fire damper blade mounting support frame includes two symmetrical support frames. A lower base plate is fixedly connected to one side of the two support frames facing each other. A mounting cover is fixedly connected to the top of the lower base plate. Two rails are fixedly connected to the top of the lower base plate. A connecting plate is provided on the top of the two rails. Two racks are fixedly connected to the bottom of the connecting plate. Two half gears are provided on the top of the lower base plate. The racks mesh with the half gears. A rotating rod is provided through the inner cavity of the half gear. A cylinder is installed on the front side of the top of the lower base plate. A connecting block is fixedly connected to the output end of the cylinder. The connecting block is fixedly connected to the connecting plate. A placement frame is provided on the top of the mounting cover. The two rotating rods pass through to the top of the mounting cover and are fixedly connected to the placement frame.

[0006] Preferably, the front side of the top of the mounting cover is fixedly connected to two symmetrical fixing sleeves, and the bottom of the placement frame is fixedly connected to two symmetrical connecting rods, with the fixing sleeves and connecting rods being rotatably connected.

[0007] Preferably, each of the two tracks has two symmetrical sliding blocks slidably connected to its top, and the sliding blocks are fixedly connected to the connecting plate.

[0008] Preferably, the top of the lower base plate is fixedly connected to two symmetrical limiting sleeves, and the two limiting sleeves are rotatably connected to the rotating rod.

[0009] Preferably, the top of the mounting cover is fixedly connected to two symmetrical mounting sleeves, and the rotating rod is rotatably connected to the mounting sleeves.

[0010] Preferably, the top of the placement rack holds the fire damper mounting shell and the fire damper blade, and the top of the mounting cover has a circular groove for fixing the mounting sleeve.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model places the fire damper housing on top of the mounting frame, and then uses the cooperation of the connecting plate, rack and pinion, and limiting sleeve to make two rotating rods rotate. In turn, the rotating rods drive the mounting frame to rotate in the top direction of the mounting cover. This achieves a structure that uses a rotating support platform to support the fire damper housing. The rotating platform drives the fire damper housing to rotate, allowing the installer to more accurately align the blade support rod with the installation point on the fire damper housing. During installation, the rotating platform drives the fire damper housing to rotate, and the blade angle can be finely adjusted at any time during the installation process. This convenient operation through the rotating platform shortens the installation time.

[0013] 2. By using the fixed sleeve and the connecting rod together, this utility model enables the connecting rod to support the placement frame when the placement frame drives the fire damper to rotate on the top of the mounting cover, ensuring that the rotational force of the placement frame when driving the fire damper to rotate is in a balanced state, thus improving the stability of the placement frame rotation.

[0014] 3. By setting up a sliding block, the sliding block guides the connecting plate when it slides, ensuring that the connecting plate will not deviate from its position when it drives the rack to move, thus improving the stability of the connecting plate's movement.

[0015] 4. By setting a limiting sleeve, this utility model ensures that when the rotating rod drives the half gear to rotate at the top of the limiting sleeve, the limiting sleeve limits the rotating rod, preventing the rotating rod from disengaging from the rack during rotation and improving the stability of the rotating rod's rotation.

[0024] In the following description, embodiments of the ventilation and fire damper blade mounting support frame of this utility model will be described with reference to the accompanying drawings.

[0025] Figure 1-5 This invention illustrates a ventilation and fire damper blade mounting support frame according to an embodiment of the present invention. It includes two symmetrical support frames 1. A lower base plate 2 is fixedly connected to one side of each support frame 1 facing each other. A mounting cover 3 is fixedly connected to the top of the lower base plate 2. Two rails 6 are fixedly connected to the top of the lower base plate 2. A connecting plate 8 is provided on the top of each rail 6. Two symmetrical sliding blocks 7 are slidably connected to the top of each rail 6. The sliding blocks 7 are fixedly connected to the connecting plate 8. Through the setting of the sliding blocks 7, when the connecting plate 8 slides, the sliding blocks 7 guide the connecting plate 8, ensuring that the connecting plate 8... The moving rack 9 does not shift its position when moving, improving the stability of the connecting plate 8. Two racks 9 are fixedly connected to the bottom of the connecting plate 8, and two half-gears 11 are provided on the top of the lower base plate 2. The racks 9 mesh with the half-gears 11, and a rotating rod 12 is inserted through the inner cavity of each half-gear 11. Two symmetrical limiting sleeves 10 are fixedly connected to the top of the lower base plate 2, and the two limiting sleeves 10 are rotatably connected to the rotating rod 12. Through the setting of the limiting sleeves 10, when the rotating rod 12 drives the half-gear 11 to rotate on the top of the limiting sleeve 10, the limiting sleeve 10 plays a limiting role in stopping the rotating rod 12, ensuring... To prevent the rotating rod 12 from disengaging from the rack 9 during rotation, thus improving the stability of the rotating rod 12, a cylinder 13 is installed on the front side of the top of the lower base plate 2. A connecting block 14 is fixedly connected to the output end of the cylinder 13. Two symmetrical mounting sleeves 15 are fixedly connected to the top of the mounting cover 3. The rotating rod 12 is rotatably connected to the mounting sleeve 15. The connecting block 14 is fixedly connected to the connecting plate 8. A placement frame 16 is provided on the top of the mounting cover 3. The two rotating rods 12 extend through to the top of the mounting cover 3 and are fixedly connected to the placement frame 16. Two symmetrical mounting blocks 14 are fixedly connected to the front side of the top of the mounting cover 3. The bottom of the mounting bracket 16 is fixedly connected to two symmetrical connecting rods 5. The mounting bracket 4 is rotatably connected to the connecting rods 5. Through the cooperation of the mounting bracket 4 and the connecting rods 5, the connecting rods 5 provide support for the mounting bracket 16 when the mounting bracket 16 drives the fire damper to rotate on the top of the mounting cover 3. This ensures that the rotational force of the mounting bracket 16 when driving the fire damper to rotate is in a balanced state, and improves the stability of the rotation of the mounting bracket 16. The top of the mounting bracket 16 is used to place the fire damper mounting shell and the fire damper blade. The top of the mounting cover 3 is provided with a circular groove for fixing the mounting bracket 15.

[0026] Working Principle: When using this utility model, the user places the fire damper housing on top of the placement rack 16. The blade support rod needs to be inserted into the installation point of one side of the fire damper housing. At this time, the cylinder 13 is activated. The output end of the cylinder 13 drives the connecting block 14 to move, which in turn drives the connecting plate 8 to move. This causes the connecting plate 8 to drive the sliding block 7 to move on top of the track 6. At this time, the rack 9 meshes with the half gear 11. Simultaneously, the connecting plate 8 drives the rack 9 to move, which in turn drives the half gear 11 to rotate. The half gear 11 drives the rotating rod 12 to rotate on top of the limiting sleeve 10. Then, the rotating rod 12 rotates within the cavity of the mounting sleeve 15, which in turn drives the top placement rack 16 to rotate on top of the mounting cover 3. This causes the placement rack 16 to drive the connecting rod 5 to rotate on top of the fixing sleeve 4. After the direction of the placement rack 16 is adjusted, the placement rack 16 stops rotating. The installer then needs to insert the blade support rod into the installation point of the other side of the fire damper housing.

[0027] In summary, this ventilation fire damper blade mounting support frame, by placing the fire damper housing on top of the mounting bracket 16, and then through the cooperation of the connecting plate 8, rack 9, and limiting sleeve 10, causes the two rotating rods 12 to rotate. The rotating rods 12 then drive the mounting bracket 16 to rotate in the top direction of the mounting cover 3, achieving a structure that uses a rotating support platform to support the fire damper housing. The rotating platform drives the fire damper housing to rotate, allowing installers to more accurately align the blade support rods with the mounting points on the fire damper housing. During installation, the rotating platform drives the fire damper housing to rotate, and the blade angle can be finely adjusted at any time. This convenient operation via the rotating platform shortens the installation time.
