Description

Technical Field

[0001] The utility model relates to the technical field of air duct hangers, in particular to an air duct hanger for a clean workshop. Background Art

[0002] The air ducts in the clean room are used to transmit gas, allowing air to circulate in the workshop and at the same time discharging the adsorbed dust out of the workshop through the air ducts.

[0003] When installing the air duct, it is necessary to use a hanger to fix it. The hanger is generally connected to the fixed frame or ceiling on the top of the workshop. However, some areas are in the earthquake zone. After an earthquake, the air duct on the top of the workshop will become a dangerous item that threatens the safety of workers. At the same time, the hangers will be disassembled into individuals before transportation, and then the individuals will be centralized and classified for transportation. However, there will always be incomplete hangers due to inconsistent quantities, which requires re-delivery. Not only does it require additional freight, but it will also delay the installation of the hanger and increase the cost of use. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] The cam is an L-shaped member formed in a pair of camshafts, each of which is connected to a pair of lockhole that is formed on a pair of locking plates at the bottom of the gear. The L-shaped member is connected to the pair of locking plates at the bottom of the gear. The lockhole that is formed on the side of the cam is formed on a pair of locking plates at the bottom of the gear.

[0007] Preferably, the threaded rod is rotatably connected to the bottom of the adjusting block in a penetrating manner, the threaded rod is symmetrically arranged, and the number of the threaded rods is two.

[0008] Preferably, the bottom of the adjustment block is symmetrically fixedly connected with a protection rod, and the threaded rod is rotatably connected inside the protection rod in a penetrating manner.

[0009] Preferably, the number of the fixing rings corresponds to the number of the protection rods, the bottom of the fixing ring is fixedly connected with an auxiliary rod, and the auxiliary rod is fixedly connected to the top of the storage block.

[0010] Preferably, both side walls of the sliding rod are fixedly connected with reinforcing ribs, one end of the reinforcing rib is fixedly connected with a fixing plate, and the middle position of the fixing plate is fixedly connected to one end of the sliding rod.

[0011] Preferably, the number of the fixed racks corresponds to the number of the connecting rods, and the number of the fixed gears corresponds to the number of the fixed racks.

[0012] Preferably, the side walls on both sides of the threaded sleeve are fixedly connected to limiting blocks, and one end of the limiting block is slidably connected to the inner wall of the protection rod.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. The utility model is provided with an adjusting block, and the sliding rod is pulled to move in the adjusting block. When the sliding rod moves, it can drive the fixed rack to engage with the fixed gear, so that the fixed gear can rotate. When the fixed gear rotates, the threaded sleeve on the threaded rod can move, thereby controlling the connecting ring to squeeze the air duct. However, when encountering vibration, the support block and the sliding block at the bottom can keep the air duct stable, thereby reducing the generation of vibration. The reduction in vibration amplitude can ensure that the amplitude of the air duct itself is reduced, and the shaking of the air duct will not aggravate the occurrence of vibration, so that the hanger can be kept as stably fixed on the top of the factory building as possible, thereby buying time for employees to escape from the factory building and avoiding collapse to threaten the lives of employees.

[0015] 2. The utility model is provided with a configuration that, during the transportation process, the sliding rod can be moved to cooperate with the adjusting block and the storage block to compress and collect the hanger, so that the hanger can be formed as an integral whole, which is convenient for installation and transportation, and can be more convenient to count the number without missing the shipment, so that the installation period of the hanger will not be delayed due to the shortage of quantity.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] A clean room air duct hanger provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides a clean workshop air duct hanger, including a sliding rod 1, the number of sliding rods 1 is two, the sliding rod 1 is L-shaped, one side of the sliding rod 1 is fixedly connected with a connecting rod 3, one end of the connecting rod 3 is slidably connected with an adjusting block 2 in a through-shaped manner, one side of the connecting rod 3 is fixedly connected with a fixed rack 4, one side of the fixed rack 4 is meshedly connected with a fixed gear 5, a threaded rod 6 is fixedly connected to the bottom center position of the fixed gear 5, one end of the threaded rod 6 is threadedly connected with a threaded sleeve 7 in a through-shaped manner, one end of the threaded sleeve 7 is fixedly connected with a connecting ring 10, one side of the connecting ring 10 is fixedly connected with a supporting block 11, one side of the supporting block 11 is fitted and slidably connected with a fixing ring 16, the inner wall of the fixing ring 16 is fixedly connected with a bearing block 12, the bearing block 12 is hollow, the inner wall of the bearing block 12 is fixedly connected with a buffer rod 13, one side of the buffer rod 13 is fitted and slidably connected with a supporting rod 14, and one side of the support rod 14 is fixedly connected with a moving block 15;

[0024] The threaded rod 6 is rotatably connected to the bottom of the adjusting block 2 in a through-shape, the threaded rod 6 is symmetrically arranged, and there are two threaded rods 6. The bottom of the adjusting block 2 is symmetrically fixedly connected with a protective rod 9, and the threaded rod 6 is rotatably connected to the inside of the protective rod 9 in a through-shape. The side walls on both sides of the sliding rod 1 are fixedly connected with reinforcing ribs 17, and one end of the reinforcing rib 17 is fixedly connected with a fixing plate 18, and the middle position of the fixing plate 18 is fixedly connected to one end of the sliding rod 1. The number of fixed racks 4 corresponds to the number of connecting rods 3, and the number of fixed gears 5 corresponds to the number of fixed racks 4. The side walls on both sides of the threaded sleeve 7 are fixedly connected with limiting blocks 8, and one end of the limiting block 8 is slidably connected to the inner wall of the protective rod 9.

[0025] In the first embodiment, the sliding rod 1 is moved by pulling the sliding rod 1. The sliding rod 1 can move with the fixed rack 4 when it moves. The fixed rack 4 can drive the fixed gear 5 to rotate when it moves. The fixed gear 5 can drive the threaded rod 6 to rotate when it rotates. The threaded rod 6 can drive the threaded sleeve 7 to rotate when it rotates. The threaded sleeve 7 can move under the intervention of the limit block 8. When moving, the threaded sleeve 7 can push the connecting ring 10 to clamp and fix the air duct. When encountering vibration, the fixed position can reduce the vibration amplitude of the air duct under the effect of the vibration force offset by the support block 11 and the support rod 14 under the moving block 15 and the buffer rod 13. When the vibration amplitude is reduced, the overall resonance amplitude of the air duct will be reduced, and then the hanger will reduce the impact caused by the vibration, and can stay on the top of the factory building for a longer time, so that employees have sufficient time to escape from the factory building and reduce casualties.

[0026] Both ends of the sliding rod 1 are slidably connected with storage blocks 20 in a penetrating manner. The number of fixing rings 16 corresponds to the number of protection rods 9. The bottom of the fixing ring 16 is fixedly connected with an auxiliary rod 19, and the auxiliary rod 19 is fixedly connected to the top of the storage block 20.

[0027] In the second embodiment, during transportation, the two sliding rods 1 can be brought close to each other, thereby compressing the space occupied by the sliding rods 1, thereby reducing the space occupied by the hanger. By integrating the hanger, it can be easily installed, and the installation time will not be delayed due to the lack of accessories, thereby ensuring the installation period.

[0028] The working principle and use process of the utility model are as follows: first, the air duct is inserted into the fixed ring 16, and then the sliding rod 1 is pulled open. When the sliding rod 1 moves, it can drive the fixed rack 4 to engage with the fixed gear 5. When the fixed gear 5 rotates, it can drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, it can drive the threaded sleeve 7 to move. When the threaded sleeve 7 moves, it can drive the connecting ring 10 to clamp the air duct. When the air duct encounters vibration, the force generated by the vibration will be transmitted to the support block 11 and the moving block 15. When the moving block 15 moves, the force can be transmitted to the support rod 14, which is then buffered by the buffer rod 13. Then, the amplitude of the vibration of the air duct is reduced under the buffering of the support block 11 and the moving block 15.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
