Description

Technical Field

[0001] This utility model relates to the field of chimney baffle technology, specifically a chimney baffle that is stable to install and not easily loosened. Background Technology

[0002] Pneumatic chimney dampers are installed on the boiler chimney. When the boiler is not running, the chimney damper can be closed, which greatly reduces the temperature drop inside the waste heat boiler, provides more energy for restarting the waste heat boiler, and reduces the boiler warm-up time.

[0003] In existing technologies, pneumatic chimney baffles are fixed at the chimney port with multiple bolts. Fixing the chimney baffle with multiple bolts is inefficient for installation and removal, and is not suitable for long-term use. The bolts are prone to loosening due to vibration. Therefore, we have introduced a chimney baffle that is stable to install and not easy to loosen. Utility Model Content

[0004] The purpose of this utility model is to provide a chimney baffle that is stable and not easily loosened. It not only facilitates the installation of the chimney baffle and has high installation efficiency, reducing the labor intensity of workers, but also ensures stable installation and prevents loosening, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A chimney baffle that is stable and not easily loosened includes a chimney port and a chimney baffle. The chimney baffle is disposed at the upper end of the chimney port. The lower end of the chimney baffle is provided with an upper ring, and the upper end of the chimney port is provided with a lower ring. The upper end of the lower ring is provided with a plurality of mounting holes evenly distributed. Mounting blocks are slidably disposed in the mounting holes. The upper end of the mounting blocks is fixedly connected to the upper ring. Each side wall of the plurality of mounting holes opposite to each other is provided with a sliding hole. A locking rod is slidably disposed in the sliding hole. The side wall of the mounting block is provided with a locking groove that cooperates with the locking rod. The rod wall of the locking rod is provided with a clamping mechanism. A linkage mechanism is provided between the plurality of locking rods.

[0006] As a further embodiment of this utility model, the clamping mechanism includes a fixed rod, the side wall of the locking rod is provided with a strip hole, the fixed rod is slidably disposed in the strip hole, both ends of the fixed rod are fixedly connected to the hole wall of the sliding hole, and a spring is fixedly provided on the side wall of the fixed rod near the mounting block.

[0007] As a further embodiment of this utility model, the linkage mechanism includes a movable ring, which is slidably sleeved outside the chimney port. A connecting rod is hinged to one end of the locking rod located outside the lower ring, and the lower end of the connecting rod is hinged to the upper side of the movable ring.

[0008] As a further embodiment of this invention, the spring is always in a compressed state.

[0009] As a further embodiment of this invention, the locking rod has a chamfer at one end near the mounting block.

[0010] As a further embodiment of this invention, the chamfer angle is set to 45°.

[0011] As a further embodiment of this invention, the number of mounting blocks is set to four.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This stable and non-loosening chimney baffle is constructed using a locking rod, chimney baffle, upper ring, lower ring, movable ring, chimney port, connecting rod, mounting block, fixing rod, and spring. During installation, pushing the movable ring upwards causes multiple locking rods to slide in opposite directions via the connecting rod. One end of the locking rod extends into the sliding hole while simultaneously compressing the spring. At this point, multiple mounting blocks on the upper ring can be engaged in the mounting holes. Releasing the movable ring allows the spring to push the locking rods into the locking grooves of the mounting blocks, completing the installation. This design not only facilitates chimney baffle installation and increases installation efficiency, reducing the labor intensity of workers, but also ensures a stable and non-loosening installation.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: A chimney baffle that is stable and not easily loosened includes a chimney port 6 and a chimney baffle 2. The chimney baffle 2 is located at the upper end of the chimney port 6. The lower end of the chimney baffle 2 is provided with an upper ring 3, and the upper end of the chimney port 6 is provided with a lower ring 4. The upper end of the lower ring 4 is provided with a plurality of mounting holes evenly distributed. Mounting blocks 8 are slidably disposed in the mounting holes. The number of mounting blocks 8 is set to four. The upper end of the mounting blocks 8 is fixedly connected to the upper ring 3. The groove wall on the opposite side of the plurality of mounting holes is provided with a sliding hole. A locking rod 1 is slidably disposed in the sliding hole. The side wall of the mounting block 8 is provided with a locking groove that cooperates with the locking rod 1. The rod wall of the locking rod 1 is provided with a clamping mechanism. A linkage mechanism is provided between the plurality of locking rods 1.

[0019] Reference Figure 3 The clamping mechanism includes a fixed rod 9, and a slotted hole is provided on the side wall of the locking rod 1. The fixed rod 9 is slidably disposed in the slotted hole. Both ends of the fixed rod 9 are fixedly connected to the hole wall of the slotted hole. A spring 10 is fixedly provided on the rod wall of the fixed rod 9 near the mounting block 8. The spring 10 is always in a compressed state.

[0020] Reference Figure 3 The linkage mechanism includes a movable ring 5, which is slidably sleeved outside the chimney port 6. A connecting rod 7 is hinged to one end of the locking rod 1 outside the lower ring 4. The lower end of the connecting rod 7 is hinged to the upper side of the movable ring 5. The linkage mechanism can facilitate the simultaneous movement of multiple locking rods 1.

[0021] Reference Figure 3 The locking rod 1 has a chamfer at one end near the mounting block 8. The chamfer angle is set to 45°, which makes it easier for the locking rod 1 to be inserted into the locking groove.

[0022] When installing the chimney baffle 2, push the movable ring 5 upward. The movable ring 5 drives multiple locking rods 1 to slide in opposite directions through the connecting rod 7. At the same time, one end of the locking rod 1 extends into the sliding hole and squeezes the spring 10. At this time, multiple mounting blocks 8 on the upper ring 3 can be inserted into the mounting holes. Release the movable ring 5, and the spring 10 pushes the locking rod 1 into the locking groove of the mounting block 8. The installation is then complete. This not only facilitates the installation of the chimney baffle 2 and improves the installation efficiency, but also reduces the labor intensity of the workers. Furthermore, the installation is relatively stable and not easy to loosen.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
