Description

Technical Field

[0001] This utility model belongs to the technical field of mine ventilation, and specifically relates to a movable air door hinge. Background Technology

[0002] As mining operations progress and roadways extend deeper, the number of air doors used to construct ventilation systems between intake and return air zones increases accordingly. The complex mine ventilation system places extremely high demands on the reliability of ventilation facilities; reliable ventilation facilities are crucial for ensuring the safe and stable operation of mine ventilation. However, the hinges currently used to ensure the rotation of air doors have certain limitations in practical applications. The proportions of the existing air door frame and door leaf are difficult to match, and in actual use, once the existing hinges are fixed, a perfect installation of the air door frame and door leaf cannot be guaranteed. Therefore, there is an urgent need to improve the air door hinges. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a movable damper hinge, which ensures perfect installation of the damper frame and the damper leaf by moving the damper hinge up and down, so as to adapt to larger size dampers.

[0004] The technical solution adopted by this utility model is a movable damper hinge, including a fixed hinge, a movable hinge, and a pin. The fixed hinge includes a hinge piece, which is fixed to the damper. The movable hinge includes a sliding block that is slidably connected to the vertical beam of the door frame. The sliding block can slide up and down along the vertical beam of the door frame. A fixed block is provided on one side of the sliding block. The fixed block is connected and fixed to the damper wall jamb by fasteners. Sleeves are provided on adjacent sides of the sliding block and the hinge piece. A pin is inserted into the sleeve to connect the two.

[0005] Furthermore, the sliding block has a groove-shaped cross-section, which is fastened to the vertical beam of the door frame.

[0006] Furthermore, the fixing block is a long rod, which is fixed to the damper wall block by U-bolts, connecting plate and nut.

[0007] Furthermore, the sliding block is provided with an upper sleeve and a lower sleeve at intervals, and the hinge piece is provided with a middle sleeve, which is located between the upper sleeve and the lower sleeve.

[0008] Furthermore, the hinge is fixed to the damper with screws.

[0009] Advantages compared to existing technologies:

[0010] 1. This utility model has a simple principle and ingenious design. By adding fasteners and a slide rail structure, the hinge position can be flexibly adjusted, thereby accurately controlling the gap between the door frame and the door leaf to ensure a perfect fit.

[0011] 2. Staff can easily adjust the hinge position by simply adjusting the fasteners, which greatly simplifies the installation process and improves work efficiency.

[0012] 3. This movable damper hinge is flexible in design and can adapt to the installation requirements of dampers of different sizes, providing more options for the design and production of dampers. Attached Figure Description

[0017] To better understand the purpose, structure, and function of this utility model, a movable damper hinge of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] like Figures 1-3 As shown, a movable damper hinge includes a fixed hinge 1, a movable hinge 2, and a pin 3. The fixed hinge 1 includes a hinge piece 11, which is fixed to the damper 4. The movable hinge 2 includes a sliding block 21 that is slidably connected to the vertical beam 5 of the door frame. The sliding block 21 can slide up and down along the vertical beam 5 of the door frame. A fixed block 22 is provided on one side of the sliding block 21. The fixed block 22 is connected and fixed to the damper wall jamb 6 by fasteners. Sleeves are provided on the adjacent sides of the sliding block 21 and the hinge piece 11. The pin 3 is inserted into the sleeves to connect the two.

[0019] In this embodiment, the hinge piece 11 is fixed to the damper 4 with screws. The sliding block 21 has a groove-shaped cross-section, which fits onto the door frame vertical beam 5. The damper frame and door leaf are perfectly installed by sliding the sliding block 21 up and down.

[0020] The sliding block 21 is provided with an upper sleeve 23 and a lower sleeve 24 spaced apart, and the hinge piece 11 is provided with a middle sleeve 12, which is located between the upper sleeve 23 and the lower sleeve 24. A pin 3 is inserted into the sleeve to realize the opening and closing of the damper 4.

[0021] The fixing block 22 is a long rod, which is fixed to the damper wall 6 by U-bolts 25, connecting plate 26, and nut 27. The U-bolts 25 fix the damper 4 to the damper wall 6, thus achieving a tight connection between the damper 4 and the damper wall 6.

[0022] This utility model's movable damper hinge is adjustable, allowing for flexible adjustment according to the actual dimensions of the damper 4. This ensures a tight fit between the door frame and the door leaf during installation, preventing gaps or misalignment. This improvement not only enhances the sealing performance of the damper 4 but also effectively extends its service life and reduces maintenance costs caused by improper installation. Furthermore, it provides more flexible options for the design and production of the damper 4, meeting the needs of different usage scenarios.
