PREFERRED EMBODIMENT

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the protection scope of the utility model. Embodiment one

[0021] Please refer to Figures 1-4The utility model provides the following technical scheme: A kind of connecting structure of building flexible ventilation pipe and main ventilation pipeline, including main ventilation pipeline body 1 and flexible ventilation pipe body 2, the butt joint end of main ventilation pipeline body 1 is connected with connecting block 3, the butt joint end of flexible ventilation pipe body 2 is connected with plug-in block 4, the side wall of connecting block 3 is equipped with through-hole 5 for plug-in block 4 to move out, recessed block 8 is installed in the bottom end of one side of connecting block 3, recessed groove 9 is equipped in the top surface of recessed block 8, plug-in slot 6 is equipped with in one side of connecting block 3, baffle 7 is inserted in the inside of plug-in slot 6, the top end of one side of connecting block 3 is connected with fixed block 10, spring 14 is assembled in the inside of fixed block 10, one end of spring 14 is installed with connecting plate 13, connecting rod 12 is installed in the side wall of connecting plate 13, limit block 11 is installed in the end of connecting rod 12.

[0022] In preferred embodiments: connecting rod 12 is connected with fixed block 10 through connecting plate 13 and spring 14.

[0023] In preferred embodiments: limit block 11 is attached to the top end of one side of connecting block 3, and the top end of baffle 7 is at the same height as the top end of connecting block 3.

[0024] In preferred embodiments: the size of through-hole 5 is the same as the size of plug-in block 4, and the size of recessed groove 9 is the same as the size of baffle 7.

[0025] In preferred embodiments: baffle 7 is detachably connected between connecting block 3 and limit block 11, and the back end of baffle 7 is attached to the outer side wall of plug-in block 4.

[0026] In preferred embodiments, when using the connecting structure, the first step is to insert plug-in block 4 with flexible ventilation pipe body 2 through through-hole 5 into connecting block 3 equipped with main ventilation pipeline body 1. Then, limit block 11 needs to be pushed backward, which will compress spring 14 and cause it to deform, with connecting rod 12 and connecting plate 13 acting in conjunction. Next, baffle 7 is removed and inserted into plug-in slot 6 until it completely passes through plug-in slot 6 and extends into recessed groove 9 on the top of recessed block 8, at which point the top end of baffle 7 is level with the top end of connecting block 3. After that, the pushing force on limit block 11 is released, allowing it to return to its original position with the help of the elasticity of spring 14, and limit block 11 will then block the top end of baffle 7, securing the position of baffle 7. At the same time, the fixation of baffle 7 also limits the escape of plug-in block 4 from through-hole 5, ensuring the secure connection of plug-in block 4 inside connecting block 3. Thus, connecting block 3 and plug-in block 4 are successfully connected, achieving the connection of main ventilation pipeline body 1 and flexible ventilation pipe body 2. In addition, the addition of a sealing ring on plug-in block 4 ensures that there is no gap between connecting block 3 and plug-in block 4, preventing the gap from affecting the connection effect of the two.

[0027] This method significantly simplifies the complexity of the traditional bolt and nut connection method, greatly reducing the complexity of installation. Since the bolt and nut connection needs to be tightened with tools, it undoubtedly increases the complexity of installation. Moreover, if the position of the nut and bolt is not proper, it is easy to misalign, which not only affects the stability of the connection, but also prolongs the installation time. What is particularly important is that in the case of high pipeline connection position, the installer needs to carry tools and work at height, which greatly increases the safety risk. Embodiment two

[0028] Please refer to Figures 1-4 The outer side wall of the connecting block 3 and the plug-in block 4 is connected with a fixing sleeve 15, the bottom end of the fixing sleeve 15 is connected with a threaded rod 16, and the end of the threaded rod 16 is installed with an extrusion block 17.

[0029] In the preferred embodiment, the extrusion block 17 is connected with the fixing sleeve 15 through the threaded rod 16 to form a threaded lifting motion.

[0030] In the embodiment, the fixing sleeve 15 is installed on the outer side of the connecting block 3 and the plug-in block 4. Then the threaded rod 16 is rotated to make it rise. With the rising of the threaded rod 16, the extrusion block 17 is driven and gradually approaches the main ventilation pipe body 1 and the flexible ventilation pipe body 2, realizing the fastening effect. This step ensures the stability of the main ventilation pipe body 1 and the flexible ventilation pipe body 2 at the connecting part of the connecting block 3 and the plug-in block 4. In this way, the problem of gap at the connecting part caused by the weight of the pipe itself can be effectively avoided, thereby improving the reliability and safety of the entire ventilation system.

[0031] It is worth noting that: the main ventilation pipe body 1 and the flexible ventilation pipe body 2 are integrally connected with the connecting block 3 and the plug-in block 4. In this way, the main ventilation pipe body 1 and the flexible ventilation pipe body 2 are connected after the connecting block 3 and the plug-in block 4 are connected.

[0032] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
