Implementation

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-3As shown, the present invention provides a technical solution: a pipe fixing device for clean heating equipment, comprising an end plate 2 and a rotating ring 14, the outer wall of the end plate 2 is wrapped with a rubber layer, when the pipe and the pipe connector on the heating equipment are installed and fixed together through the device, the pipe connector on the heating equipment and the end of the pipe are tightly fitted on the two end plates 2 respectively, and the rubber layer will seal the gap between the end plate 2 and the pipe and the pipe connector to avoid leakage when the fluid flows through the device, the front and rear ends of the rotating ring 14 are provided with end plates 2, and the opposite side edges of the two end plates 2 are provided with annular grooves 23, the front and rear ends of the rotating ring 14 are fixed with slip rings 22, and the two slip rings 22 are respectively located inside the two annular grooves 23 , and are slidably connected with the two annular grooves 23 respectively. The vertical cross-sections of the annular groove 23 and the slip ring 22 are both T-shaped structures. The top, bottom and side of the slip ring 22 away from the rotating ring 14 are embedded with rolling balls 24. The outer wall of the rolling ball 24 fits with the inner wall of the annular groove 23 to avoid the end plate 2 and the rotating ring 14 from being separated from each other. At the same time, the rotating ring 14 can be rotated more smoothly. A channel 6 is fixed in the middle of the two end plates 2. The front and rear ends of the channel 6 are respectively located on the opposite sides of the two end plates 2. A plurality of slide grooves 5 are equidistantly provided on the opposite sides of the two end plates 2. Two connecting rods 10 are slidably connected inside the slide groove 5. Flexible sealing pads 9 are fixed on the opposite sides of the two connecting rods 10 in the same slide groove 5. Two flexible The ends of the sealing gasket 9 away from the connecting rod 10 are fixedly connected to the inner top and inner bottom of the slide groove 5 respectively. When the inner and outer fixing plates are close to each other to clamp the pipe or the pipe connector for fixing, the flexible sealing gasket will unfold, thereby sealing the slide groove 5 on the opposite sides of the two connecting rods 10 to prevent the fluid from entering the interior of the device when passing through the fixing device, and at the same time prevent impurities from the outside air from entering the device. One end of the two connecting rods 10 is located on the side of the end plate 2 away from the rotating ring 14, and an outer fixing plate 1 and an inner fixing plate 4 are fixed respectively. The outer fixing plate 1 and the inner fixing plate 4 are both elastic arc-shaped plate structures, and rubber pads 3 are fixed on the opposite sides of the outer fixing plate 1 and the inner fixing plate 4. The pipe connector and the pipe can be fixed together through the inner and outer fixing plates. The device is fixed thereon, and the inner and outer fixing plates made of elastic material can make the fixing plates adapt to pipes and connectors of different diameters. In addition, the rubber pad 3 can increase the friction between the inner and outer fixing plates and the pipes and the pipe connectors, so that the pipes and the pipe connectors can be more firmly fixed on the device, thereby making the connection between the pipes and the pipe connectors more firmly. The outer wall of the channel 6 is evenly fixed with a plurality of threaded rods 12, and the plurality of threaded rods 12 correspond one to one with the plurality of slide grooves 5. The other end of the connecting rod 10 is fixed with a threaded sleeve 11, and the threaded sleeve 11 is sleeved on the outer wall of the threaded rod 12 and is threadedly connected with the threaded rod 12. A first gear 17 is fixed to the outer wall of the threaded rod 12 near the channel 6, and a plurality of support frames 16 are evenly fixed to the outer wall of the channel 6.The plurality of support frames 16 correspond to the plurality of threaded rods 12 one by one. The end of the support frame 16 away from the channel 6 is rotatably connected to the second gear 13. The second gear 13 meshes with the first gear 17. The diameter of the second gear 13 is three times the diameter of the first gear 17. The rotating ring 14 can be rotated at a smaller angle to fix the pipeline and the pipeline connector, which is convenient for the operator to operate. The inner side wall of the rotating ring 14 is fixed with an inner gear ring 15. The inner gear ring 15 meshes with the second gear 13. The inner side wall of the rotating ring 14 is fixed with an inner gear ring 15. A ratchet ring 21 is fixed at the middle, a button 7 is provided at the bottom of the front surface of the front end plate 2, a cross bar 8 is fixed at the middle of the rear end of the button 7, the rear end of the cross bar 8 passes through the front end plate 2 and extends to the inside of the rotating ring 14, a spring 18 is fixed at the rear end of the cross bar 8, the rear end of the spring 18 is fixedly connected to the front surface of the rear end plate 2, a hollow rectangular connecting piece 19 with openings at the bottom and right side is fixed at the bottom of the cross bar 8, a ratchet 20 is rotatably connected to the inside of the connecting piece 19 through a torsion spring, and the ratchet 20 is engaged with the ratchet ring 21.

[0023] In summary, the working process of the present invention is as follows: when in use, the pipe connector of the heating equipment and the pipe to be installed are respectively fitted on the opposite sides of the two end plates 2 of the device, and then the rotating ring 14 is rotated. At this time, the second gear 13 is driven to rotate under the action of the internal internal gear ring 15, and the first gear 17 is driven to rotate. The first gear 17 drives the threaded rod 12 to rotate, so that the two threaded sleeves 11 on the threaded rod 12 can be moved closer to each other, and the connecting rod 10 and the inner and outer fixed plates on the connecting rod 10 can be driven to move closer to each other. The inner and outer fixed plates with elastic and arc-shaped structures can clamp the pipe and the pipe connector, so that the pipe can be installed and fixed on the pipe connector through the device. And in the process again, when the rotating ring 14 is rotated, the ratchet ring 21 will cause the pawl 20 to rotate toward the side of the opening of the connecting piece 19 to prevent the pawl 20 from getting stuck in the ratchet ring 21, thereby causing the rotating ring 14 to be unable to rotate. When the pipeline is installed and fixed on the heating equipment, the rotating ring 14 is released at this time. At this time, the rotating ring 14 has a tendency to rotate in the opposite direction. At this time, the ratchet ring 21 will drive the pawl 20 to rotate toward the closed side of the connecting piece 19 and be blocked. At this time, the ratchet 20 will get stuck in the ratchet ring 21 to prevent the rotating ring 14 from rotating in the opposite direction, causing the pipeline to loosen. When the pipeline is damaged and needs to be replaced, the button 7 is pressed to drive the cross bar 8 to move backward. At this time, the pawl 20 is disengaged from the ratchet ring 21, and then the rotating ring 14 is rotated in the opposite direction. At this time, the first gear 17 and the second gear 13 both rotate in the opposite direction, and the threaded rod 12 also rotates in the opposite direction, so that the two threaded sleeves 11 move away from each other, and the inner and outer fixing plates move away from each other, and the pipeline is loosened. Then, the button 7 is opened, and the cross bar 8 and the button 7 are returned to their original positions under the action of the spring 18. At the same time, the pawl 20 is engaged with the ratchet ring 21 again, and then the new pipeline and the heating equipment are installed according to the above-mentioned operation of installing the pipeline.
