[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a heating and ventilation duct that is easy to install, including a ventilation pipe 1, a base 2 at the top of the ventilation pipe 1, a lifting assembly at the top of the base 2, a frame 3 at the top of the lifting assembly, an adjustment assembly inside the frame 3, and two fixing plates 4 at the top of the adjustment assembly. Each fixing plate 4 has a through hole 5. By setting up the lifting assembly, the height of the frame 3, the fixing plates 4, and the through hole 5 can be adjusted. This solves the problem that the installation bracket 6 of the existing ventilation pipe 1 does not have a height adjustment function, resulting in limited flexibility during use and inability to be effectively fixed when the ceiling height changes. By setting up the adjustment assembly, the distance between the two fixing plates 4 can be adjusted, making it convenient to adjust the position of the through hole 5 according to the position of the threaded hole on the ceiling, thus improving the flexibility during use.

[0022] In this embodiment, the adjustment assembly includes a bracket 6, a worm gear 7, a knob 8, a screw 9, a worm wheel 10, a movable cylinder 11, and a telescopic assembly. The bracket 6 is located at the top of the base 2. One end of the worm gear 7 is rotatably connected to the left side of the inner cavity of the bracket 6 via a bearing, and the other end of the worm gear 7 extends to the front end of the bracket 6 and is fixedly connected to the knob 8. One end of the screw 9 is rotatably connected to the top of the base 2 via a bearing. The movable cylinder 11 is screwed onto the outer wall of the screw 9 and fixedly connected to the bottom end of the frame 3. The telescopic assembly is located between the base 2 and the frame 3. Rotating the knob 8 causes the knob 8 to drive the worm gear 7 to rotate. Since the worm 7 meshes with the worm wheel 10, when the worm 7 rotates, the worm wheel 10 can drive the screw 9 to rotate. Under the rotational force of the screw 9's outer wall thread, when the screw 9 rotates, the moving cylinder 11 can drive the frame 3, the fixed plate 4, and the through hole 5 to slide up and down in a straight line under the limiting action of the telescopic rod 13 and the telescopic cylinder 12. This solves the problem that the existing ventilation duct 1's mounting bracket 6 does not have a height adjustment function, has limited flexibility in use, and cannot be effectively fixed when the ceiling height changes.

[0023] In this embodiment, the worm 7 meshes with the worm wheel 10, which allows the worm wheel 10 to rotate when the worm 7 rotates. At the same time, the worm wheel 10 and the worm 7 have a self-locking effect to prevent the screw 9 from rotating on its own.

[0024] In this embodiment, the telescopic assembly includes a telescopic cylinder 12, a telescopic rod 13, and a connecting assembly. The telescopic cylinder 12 is located at one of the top corners of the base 2. The telescopic rod 13 is slidably inserted into the inner cavity of the telescopic cylinder 12 and fixedly connected to one of the bottom corners of the frame 3. The connecting assembly is located in the inner cavity of the telescopic cylinder 12 and fixedly connected to the outer wall of the telescopic rod 13. Under the combined action of the telescopic cylinder 12 and the telescopic rod 13, the frame 3 can always slide up and down along a straight line.

[0025] In this embodiment, the connecting assembly includes a connecting groove and a connecting block. The connecting groove is formed in the inner cavity of the telescopic cylinder 12. The connecting block is slidably embedded in the inner cavity of the connecting groove and fixedly connected to the outer wall of the telescopic rod 13. Under the combined action of the connecting block and the connecting groove, one end of the telescopic rod 13 can always be inserted into the inner cavity of the telescopic cylinder 12, which improves the stability of the telescopic assembly during use. The inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped, which can ensure that one end of the connecting block is always embedded in the inner cavity of the connecting groove, which improves the stability of the connecting assembly during use.

[0026] In this embodiment, the adjustment assembly includes a lead screw 16, a handle 17, a guide rod 18, and sliders 19. One end of the lead screw 16 is rotatably connected to the right side of the inner cavity of the frame 3 via a bearing, and the other end of the lead screw 16 extends to the left end of the frame 3 and is fixedly connected to the handle 17. The guide rod 18 is disposed in the inner cavity of the frame 3 and is parallel to the lead screw 16. Two sliders 19 are respectively screwed to the left and right sides of the outer wall of the lead screw 16 and are respectively slidably sleeved on the left and right sides of the outer wall of the guide rod 18. The two sliders 19 are respectively fixedly connected to two fixed plates 4. Rotating the handle 17 causes the handle 17 to drive the lead screw 16 to rotate, thereby generating a relative thread rotation force on the opposite threads on the left and right sides of the outer wall of the lead screw 16. Under the limiting action of the guide rod 18, the two sliders 19 slide relative to each other simultaneously, thereby adjusting the distance between the two fixed plates 4. This facilitates the adjustment of the position of the through hole 5 according to the position of the threaded hole reserved on the ceiling, improving the flexibility during use.

[0027] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 16 are arranged opposite to each other, so that when the lead screw 16 rotates, the left and right sides of its outer wall generate relative thread rotational forces, so that the two sliders 19 slide relative to each other simultaneously under the limiting action of the guide rod 18.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
