[0026] Figures 1-5In one embodiment of this utility model, a heating and ventilation pipe for heating and ventilation engineering includes a pipe 1 and a base 2 located below the pipe 1. Two sets of retaining rings 5 are fixedly installed at both ends of the pipe 1, and a retaining groove 3 is provided at the left end of the pipe 1 and a retaining tube 4 is provided at the right end of the pipe 1. The retaining tubes 4 between the two sets of pipe 1 are correspondingly arranged with the retaining grooves 3. A first bidirectional screw 6 and a second bidirectional screw 7 are respectively installed in the base 2. A connecting mechanism 8 for quickly connecting the pipe 1 and an anti-detachment mechanism 9 for preventing the pipe 1 from loosening are provided above the base 2. The connecting mechanism 8 includes two sets of mounting seats 801 symmetrically distributed on the base 2 and multiple sets of adjusting brackets 805 distributed in a ring on the mounting seats 801. Each of the multiple adjusting brackets 805 is equipped with a retaining plate 808. The retaining plate 808 is movably engaged with the pipe 1 through the retaining rings 5. An mounting ring 802 is rotatably installed in the mounting seat 801, and an inner and outer toothed ring 8 is sleeved on the mounting ring 802. 03. Multiple sets of adjusting brackets 805 are rotatably connected to the mounting base 801 via rotating rods 806. Gears 807 are sleeved on multiple sets of rotating rods 806, and multiple sets of gears 807 are meshed with inner and outer gear rings 803. The anti-detachment mechanism 9 includes two sets of fixed seats 901 symmetrically distributed on the base 2, and the two sets of fixed seats 901 are respectively distributed with the two sets of mounting bases 801. Four sets of damping rods 902 are symmetrically distributed between the fixed seats 901 and the mounting bases 801. Three sets of annularly distributed sliding grooves 904 are opened on the two sets of fixed seats 901. Three sets of annularly distributed clamping rods 910 are provided on the fixed seats 901. The quick alignment and clamping between the two sets of pipes 1 is achieved through the set clamping tubes 4 and clamping grooves 3. The quick and accurate fixation between the two sets of pipes 1 is achieved through the setting of the two sets of mounting bases 801, adjusting brackets 805, clamping plates 808 and clamping rings 5 on pipes 1 in the connecting mechanism 8.
[0027] In this embodiment, reference Figure 2 , Figure 3 , Figure 4As shown, the two ends of the first bidirectional screw 6 pass through the base 2 and are rotatably connected to the base 2. The two ends of the first bidirectional screw 6 pass through two sets of mounting seats 801 and are threadedly connected to the two sets of mounting seats 801 respectively. A drive wheel 804 is rotatably installed inside the mounting seat 801, and the drive wheel 804 is rotatably connected to the mounting seat 801 through a rotating shaft. The drive wheel 804 is meshed with the inner and outer toothed rings 803. Both sets of fixed seats 901 are slidably connected to the base 2. The two ends of the second bidirectional screw 7 pass through the base 2 and are rotatably connected to the base 2. The two ends of the second bidirectional screw 7 pass through two sets of fixed seats 901 and are threadedly connected to the two sets of fixed seats 901 respectively. After the quick alignment and snapping between the two sets of pipes 1 is achieved by the clamp 4 and the clamp 3, the two sets of pipes 1 pass through the mounting seats 801. After mounting base 801 is installed, the motor inside mounting base 801 is started to drive the drive wheel 804 to rotate. During the rotation of drive wheel 804, the inner and outer gear rings 803 and mounting ring 802 rotate within mounting base 801, thereby causing multiple sets of gears 807 meshing with the inner and outer gear rings 803 to drive the corresponding rotating rods 806 and adjusting brackets 805 to rotate. Multiple sets of adjusting brackets 805 rotate synchronously, causing multiple sets of clamping plates 808 to converge synchronously and fit against the outer wall of pipe 1. Then, the motor inside base 2 is started to drive the first bidirectional screw 6 to rotate. Under the limiting action of base 2, the two sets of mounting bases 801 drive the clamping plates 808 to slide inward synchronously, and the clamping plates 808 respectively fit against the corresponding clamping rings 5, thereby fixing and reinforcing the connection between the two sets of pipes 1.
[0028] In this embodiment, reference Figure 5As shown, a spring 903 is sleeved on the damping rod 902. The two ends of the damping rod 902 are fixedly connected to the fixed seat 901 and the mounting seat 801, respectively. Three sets of clamping rods 910 are respectively attached to the outer wall of the pipe 1. The three sets of clamping rods 910 are respectively distributed with three sets of sliding grooves 904. A slider 911 is fixedly installed on each of the three sets of clamping rods 910. A mounting plate 905 is rotatably installed inside the fixed seat 901. A toothed ring 906 is sleeved on the mounting plate 905. A rack 907 is slidably mounted inside the mounting base 901, a cylinder 908 is housed within the mounting base 901, and a ring gear 909 is fixedly mounted on the mounting plate 905. The rack 907 meshes with the ring gear 906, and the rack 907 is connected to the output end of the piston rod of the cylinder 908. A slider 911 is slidably connected to the mounting base 901 via a sliding groove 904, and the slider 911 is meshed with the mounting plate 905 via the ring gear 909. The mounting base 801, adjusting bracket 805, and clamping plate 805 are used in conjunction with these components. After the initial connection and fixation between the two sets of pipes 1, the cylinder 908 in the fixing seat 901 is activated to drive the rack 907 to slide. This, in conjunction with the gear ring 906, causes the mounting plate 905 to rotate. The ring gear 909 rotates synchronously with the mounting plate 905. Under the limiting action of the slide groove 904, the three sets of sliders 911 connected to the mounting plate 905 by the ring gear 909 slide inward synchronously, causing the three sets of clamping rods 910 to fit against the outer wall of the corresponding pipe 1, thus supporting and fixing the pipe 1. The motor in the base 2 is activated to drive the rotation of the second bidirectional screw 7. Under the limiting action of the base 2, the two sets of fixing seats 901 slide inward synchronously to a certain extent, compressing the damping rod 902 and the spring 903. The damping rod 902 and the spring 903 abut against the corresponding mounting seat 801, so that even if the gas pressure in the pipe 1 is high, the connection of the pipe 1 will not be loose or gaps will appear.
[0029] In this embodiment, after the two sets of pipes 1 are quickly aligned and engaged by the clamping tube 4 and the clamping groove 3, the two sets of pipes 1 pass through the mounting base 801. The motor inside the mounting base 801 is started to drive the drive wheel 804 to rotate. During the rotation of the drive wheel 804, the inner and outer gear rings 803 and the mounting ring 802 rotate within the mounting base 801. This causes multiple sets of gears 807 meshing with the inner and outer gear rings 803 to drive the corresponding rotating rods 806 and adjusting brackets 805 to rotate. The multiple sets of adjusting brackets 805 rotate synchronously, causing multiple sets of clamping plates 808 to converge synchronously and fit against the outer wall of the pipe 1. Then, the motor inside the base 2 is started to drive the first bidirectional screw 6 to rotate. Under the limiting action of the base 2, the two sets of mounting bases 801 drive the clamping plates 808 to slide inward synchronously, and the clamping plates 808 respectively fit against the corresponding clamping rings 5, thus fixing and reinforcing the connection between the two sets of pipes 1. After the initial connection and fixation between the two sets of pipes 1 by the clamping plate 808 and the clamping plate 808, the cylinder 908 in the fixing seat 901 is activated to drive the sliding of the rack 907. This, in conjunction with the gear ring 906, causes the mounting plate 905 to rotate. The ring gear 909 rotates synchronously with the mounting plate 905. Under the limiting action of the sliding groove 904, the three sets of sliders 911 connected to the mounting plate 905 by the ring gear 909 slide inward synchronously, causing the three sets of clamping rods 910 to fit against the outer wall of the corresponding pipe 1, thus supporting and fixing the pipe 1. The motor in the base 2 is activated to drive the rotation of the second bidirectional screw 7. Under the limiting action of the base 2, the two sets of fixing seats 901 slide inward synchronously to a certain extent, compressing the damping rod 902 and the spring 903. The damping rod 902 and the spring 903 abut against the corresponding mounting seat 801, so that even if the gas pressure in the pipe 1 is high, the connection of the pipe 1 will not be loose or gaps will appear.
