Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a heating ventilation duct. Background Art

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air-conditioning projects in industrial and civil buildings. Existing ventilation ducts are inconvenient to connect and disassemble during installation, which affects installation efficiency.

[0003] According to the Chinese patent application number 202222689347.4, a heating and ventilation duct that is easy to install is proposed. Through the mutual cooperation between the first mounting frame, the second mounting frame, the spring, the slot, the mounting column, the block, the mounting slot, the fixing block and other structures, the heating and ventilation duct is conveniently installed and fixed quickly. Compared with the existing technology using bolts and flanges for installation, the efficiency of installation and disassembly of the ventilation duct is greatly improved, making it easier for people to use.

[0004] However, after the above patent was improved, since the device fixes the two pipes through the components inside the first mounting frame, when a pipe is damaged and needs to be replaced, it is necessary to move the second pipe toward the other side to remove it during disassembly. Since the heating pipe is connected by multiple pipes, they need to be disassembled in sequence. The whole process is time-consuming and labor-intensive. For this reason, we propose a heating and ventilation duct. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides a heating and ventilation pipe, which solves the problem of time-consuming and labor-intensive pipe replacement proposed in the above background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a heating and ventilation duct, including a duct body, wherein the corresponding two ends of the duct body are fixedly installed with a first frame and a second frame respectively, the corresponding two sides of one side of the first frame are fixedly installed with sliders, the corresponding two sides of one side of the second frame are provided with a slide groove, the slider is slidably connected to the slide groove, the interior of the second frame and a baffle is slidably connected on one side of the slide groove, the baffle contacts the side of the slider close to each other, the corresponding two sides of the second frame are provided with a groove, two springs are provided inside the groove, the other ends of the two springs are fixedly installed with a fixing block, a fixing hole is provided on one side of the baffle, the fixing block is clamped with the fixing hole, and a connecting plate is fixedly installed on the top of the fixing block, and the connecting plate is slidably connected to the groove.

[0007] Preferably, the connecting plate is connected to a rotating shaft for internal rotation, a handwheel is fixedly installed at one end of the rotating shaft and located on the outside of the connecting plate, a gear is fixedly installed on the outside of the rotating shaft and located on the inside of the connecting plate, a rack is slidably connected to the inside of the connecting plate and on the corresponding two sides of the gear, the gear and the rack are meshed together, and an inner hole is opened inside the second frame and on the corresponding two sides of the groove, the rack is engaged with the inner hole, and the rotating shaft is driven to rotate by turning the handwheel, and the rotating shaft drives the outer gear to rotate, and the cooperation between the gear and the rack makes the racks on both sides inserted into the corresponding inner holes, so that the connecting plate can be limited, thereby improving the fixing effect between the pipeline bodies.

[0008] Preferably, the slider and the slide groove are both T-shaped structures, which play a limiting role, prevent the slider from shaking, and further improve the stability of the connection between the two pipe bodies.

[0009] Preferably, a sealing gasket is fixedly installed on the side where the first frame and the second frame are close to each other to play a sealing role and prevent the internal heating from leaking.

[0010] Preferably, a fixing frame is fixedly installed on the outer side of the pipe body, and pull rings are fixedly installed on the corresponding two sides of the top of the fixing frame. The steel wire rope can be passed through the pull rings and fixed to the wall, thereby improving the stability of the installation of the pipe body.

[0011] Preferably, the fixing block is in a beveled shape. By providing the beveled fixing block, the baffle can push the fixing block to move toward the other side when squeezing the fixing block, thereby avoiding a jamming phenomenon.

[0012] The utility model provides a heating ventilation pipe, which has the following beneficial effects:

[0013] 1. The heating and ventilation duct is provided with an installation mechanism, and the slider on one side of the first frame is inserted into the slide groove on one side of the second frame, and then the baffle is moved. At the same time, the baffle is squeezed on the fixing block during the movement, so that it moves toward one side of the spring until the baffle and the slider are completely in contact with each other. At this time, the fixing block is pushed into the corresponding fixing hole by the rebound force of the spring, so that the first frame and the second frame can be connected together to complete the splicing between the two pipe bodies. The whole process is more convenient and quick. At the same time, when one of the pipe bodies is damaged and needs to be replaced, it is only necessary to toggle the connections on both sides so that it drives the fixing block to no longer be engaged with the fixing hole, and then move the baffle toward the side close to each other, so that the baffle no longer limits the slider, so that the damaged pipe body can be directly taken out without the need to disassemble the pipe bodies one by one, thereby improving the maintenance efficiency of the device.

[0014] 2. The heating ventilation duct further improves the sealing between the two pipe bodies by arranging a sealing gasket between the first frame and the second frame, thereby preventing leakage of internal heating and avoiding unnecessary losses. By arranging a slider and a slide groove of a T-shaped structure, it can effectively prevent the slider from shaking inside the slide groove, further improving the stability between the two pipe bodies.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 4The cam 32 is connected with the second frame 31 and the second frame 32 is connected with the cam 32. When the cam 35 is in the closed position, the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position and the cam 35 is in the closed position.

[0022] The interior of the connecting plate 37 is rotatably connected to the rotating shaft 4, and a handwheel 41 is fixedly installed at one end of the rotating shaft 4 and located on the outside of the connecting plate 37. A gear 42 is fixedly installed on the outside of the rotating shaft 4 and located on the inside of the connecting plate 37. A rack 43 is slidably connected to the interior of the connecting plate 37 and on the corresponding sides of the gear 42. The gear 42 is meshed with the rack 43. The interior of the second frame 3 and on the corresponding sides of the groove 33 are provided with an inner hole 44, and the rack 43 is engaged with the inner hole 44. Turning the handwheel 41 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the outer gear 42 to rotate. Through the meshing of the gear 42 and the rack 43, the rack 43 can be driven to move toward the side away from each other and inserted into the corresponding inner hole 44, so that the connecting plate 37 can be limited again, thereby improving the stability of the connection of the pipeline body 1. The slider 21 and the slide groove 31 are both T-shaped structures, which prevent the slider 21 from shaking inside the slide groove 31, thereby improving the stability of the connection between the pipeline bodies 1.

[0023] A sealing gasket 5 is fixedly installed on the side where the first frame 2 and the second frame 3 are close to each other, which plays a sealing role, avoids harm caused by heating leakage, and improves the safety of the device. A fixing frame 6 is fixedly installed on the outside of the pipe body 1, and pull rings 61 are fixedly installed on both sides of the top of the fixing frame 6. The steel wire rope is passed through the pull ring 61 and fixed to the wall, so that it can be supported to improve the stability of the device. The fixing block 35 is in a hypotenuse shape. By setting the hypotenuse-shaped fixing block 35, when the baffle 32 squeezes the fixing block 35, it can push the fixing block 35 to move, preventing the fixing block 35 from getting stuck on the baffle 32.

[0024] To sum up, when the heating and ventilation duct is in use, the staff inserts the two sliders 21 on one side of the first frame 2 into the slide groove 31 opened on the other side of the second frame 3. At the same time, since the slider 21 and the slide groove 31 are both T-shaped structures, they can effectively prevent the slider 21 from shaking, further improving the fixing effect of the device. When the slider 21 moves to the innermost side of the slide groove 31, the staff moves the baffles 32 on both sides to move it toward the side away from each other. During the movement, the baffle 32 squeezes the fixed block 35 to move it toward the side of the spring 34 until the baffle 32 is completely in contact with the side of the slider 21 that is close to each other. At this time, the rebound force of the spring 34 is used to push the fixed block 35. The block 35 moves toward one side of the baffle 32 and is inserted into the corresponding fixing hole 36, so that the baffle 32 can be fixed, so that it can always limit the slider 21 to prevent the slider 21 from disengaging from the slide groove 31 during use, avoiding the formation of a gap between the two pipe bodies 1, preventing the internal heating from leaking, and improving the practicality of the device. Then the staff turns the handwheel 41 to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the outer gear 42 to rotate, and uses the gear 42 to engage with the rack 43, so that the two racks 43 move toward the side away from each other and are inserted into the opened inner hole 44, so that they limit the connecting plate 37, further improving the fixing effect of the device.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
