Description

Technical Field

[0001] This utility model relates to the technical field of air distributor equipment, specifically to a modular quick-release air duct structure for a ship air distributor. Background Technology

[0002] Marine air distributors are devices that evenly distribute air to all parts of the ship's cabin, avoiding the problems of concentrated air supply in some areas and dead air in others. Typically, air distributors consist of a supply unit, connecting pipes, and an outlet structure. Existing air distributor ducts have a single, standardized structure, containing only fixed-length branch pipes and a certain number of bends. This necessitates customized installation design based on the installation environment, preventing modular design of the duct structure and increasing overall production costs. Furthermore, the need for individual installation plans based on the site conditions complicates the installation process. Therefore, we plan to improve and upgrade the traditional make-up air fan duct structure by designing a modular structure to reduce production and installation costs. Utility Model Content

[0003] The purpose of this utility model is to address the defects and deficiencies of the existing technology by providing a modular quick-release air duct structure for a ship air distributor.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-4 As shown, the specific implementation adopts the following technical solution: It includes a connecting pipe 1 and a telescopic pipe 2. Two telescopic pipes 2 are symmetrically inserted into the left and right ends of the connecting pipe 1. A flange head 8 is fixedly fitted onto one end of the telescopic pipe 2 extending from the connecting pipe 1. A drive shaft 5 is screwed onto the front wall of the connecting pipe 1 via a bearing. Guide rods 3 are provided on both the upper and lower sides of the drive shaft 5, and the guide rods 3 are fixedly mounted on the front wall of the connecting pipe 1. The guide rods 3 have a splined rod structure, and guide sleeves 4 are fitted onto the guide rods 3. The upper and lower guide sleeves 4 are symmetrically arranged. The guide sleeves 4 have a splined sleeve structure, thus guiding the... Linear support and guidance are achieved through a spline connection between guide sleeve 4 and guide rod 3. A gear 6 is fixedly mounted on drive shaft 5. A rack 7 is integrally formed on the wall of guide sleeve 4 facing gear 6, and the rack 7 meshes with gear 6. A support rod 9 is fixedly mounted on flange head 8. A limit block 21 is fixedly mounted on the movable end of support rod 9. A support sleeve 11 is movably mounted on support rod 9. A connecting seat 10 is fixedly mounted on guide sleeve 4. The support sleeve 11 is fixedly mounted on connecting seat 10. A support spring 12 is mounted on support sleeve 11, and one end of support spring 12 abuts against... On the side wall of flange head 8, the other end of support spring 12 abuts against the end wall of support sleeve 11 away from limit block 21; mounting brackets 13 are fitted on both the left and right sides of drive shaft 5 on connecting pipe 1, and buckles 14 are fixedly installed on the inner wall of mounting bracket 13, and buckles 14 are engaged and abut against the front side wall of connecting pipe 1; lugs 15 are fixedly installed at both the upper and lower ends of the rear end plate of mounting bracket 13; connecting bracket 16 is screwed onto the front end of drive shaft 5 through bearing, and the left and right ends of connecting bracket 16 are respectively fixed on the mounting brackets 13 on the left and right sides; drive shaft 5 A ratchet 17 is fixedly mounted on the upper sleeve and is located inside the connecting frame 16. A spring pawl 18 is fixedly mounted on the inner wall of the connecting frame 16, and the movable pawl end of the spring pawl 18 is supported by a spring structure, so that the movable pawl end of the spring pawl 18 is engaged with the ratchet 17. A pin 20 is fixedly mounted on the movable pawl end of the spring pawl 18. A waist-shaped hole 19 is opened on the connecting frame 16, and the pin 20 is movably inserted into the waist-shaped hole 19. The spring pawls 18 are arranged symmetrically on the left and right, and the movable pawl ends of both spring pawls 18 are engaged with the ratchet 17.

[0018] When using this device, it is mounted and fixed on the base plate using the lugs 15. The telescopic tubes 2 on both sides connect to the multiple sections of the pipes on both sides, thus achieving the connection of the air distributor duct through the connecting pipes 1 and 2. During installation, only the connecting pipes 1 need to be installed and fixed, and the telescopic tubes 2 on both sides need to be adjusted to extend and connect with the pipes on both sides via the flanges 8. After the connecting pipes 1 are installed, the drive shaft 5 is rotated using a tool. During this process, the ratchet pawl 18 engages the ratchet 17, achieving unidirectional rotation of the drive shaft 5. The drive shaft 5 drives the gear 6 to rotate, which in turn pushes the rack 7, causing the guide sleeve 4 to slide on the guide rod 3. The guide sleeve 4 pushes the support sleeve 11 through the connecting seat 10, and the support sleeve 11 is held in place by the support spring 12. The flange head 8, and then the support sleeve 11 pushes the telescopic pipe 2 to move towards the extension connecting pipe 1. The telescopic pipe 2 extends and abuts against the port of the external pipe through the flange head 8, realizing the connection between the external pipe and the telescopic pipe 2. And because the gear 6 pushes the racks 7 on both sides to move synchronously, that is, the support sleeves 11 on both sides move synchronously. When the distance between the telescopic pipe 2 on both sides and their respective external pipes is different, when the flange head 8 on one side of the telescopic pipe 2 abuts against the external pipe joint and prevents the telescopic pipe 2 from continuing to move, as the support sleeve 11 continues to move, the support sleeve 11 will press and retract the support spring 12. When the telescopic pipe 2 is in a free and automatic state, the support spring 12 supports between the flange head 8 and the support sleeve 11, thereby driving the support rod 9 through the flange head 8, so that the limit block 21 on the support rod 9 abuts against the support sleeve 11.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This device is installed by setting movable telescopic tubes 2 in the left and right ports of the connecting pipe 1 and installing flange heads 8 on the ends of the telescopic tubes 2. During installation, the device is fixed to the base plate by the lugs 15 on the mounting bracket 13. Then, by extending the telescopic tube 2 and pressing the flange head 8 against the end of the external pipe, the external pipe, the telescopic tube 2, and the connecting pipe 1 are connected and installed. 2. This device sets symmetrical racks 7 on both sides of the gear 6 and drives the guide sleeve 4 to move. The guide sleeve 4 is connected to the support sleeve 11 through the connecting frame 16. The support sleeve 11 is connected to the flange head 8 on the telescopic pipe 2 through the support rod 9 with the support spring 12. Thus, the gear 6 drives the rack 7 to rotate. Through the contraction support of the support spring 12, both sides of the telescopic pipe 2 can be connected to the corresponding pipe.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
