Description

Technical Field

[0001] The utility model relates to the technical field of connection devices, and particularly relates to a flexible connection structure for a ventilation pipe of a ventilator. Background Art

[0002] In the fields of industrial and civil buildings, the ventilation pipe system of a ventilator plays a crucial role in maintaining indoor air quality. Due to the fact that building structures may bend or move due to temperature changes, foundation settlement, or other factors, flexible pipe connections are essential in the ventilation pipe system of a ventilator. Such flexible connections can adapt to structural changes and ensure the integrity and functionality of the pipe system.

[0003] However, during the operation of replacing the flexible hose, since the ventilation pipes are usually fixedly installed, it is necessary to first precisely dock the end of the flexible hose with the end of the ventilation pipe, and then fix it through a crimping joint. During this process, the staff cannot fix the hose to the pipe in advance, and the hose will fall off from the pipe under the influence of factors such as the operation of the staff or mechanical vibration, requiring the staff to reconnect, which affects the installation efficiency. For this reason, we propose a flexible connection structure for a ventilation pipe of a ventilator. Content of the Utility Model

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to the attached Figures 1-6 , this practical embodiment provides a flexible connection structure for a ventilator pipeline, including a hose 1 and a crimping joint 2 connected to its end. The crimping joint 2 includes a connecting pipe 21, a first crimping pliers 3, and a second crimping pliers 4. The two ends of the connecting pipe 21 are sleeved with the first crimping pliers 3 and the second crimping pliers 4. The second crimping pliers 4, the connecting pipe 21, and the first crimping pliers 3 are all semicircular structures and surround the end of the hose 1. The second crimping pliers 4 is fixedly connected to the connecting pipe 21, and the first crimping pliers 3 is detachably connected to the connecting pipe 21. An annular groove 41 for sleeving a flange is also provided on the inner wall of the second crimping pliers 4;

[0027] To facilitate the installation of the hose 1 on the crimping joint 2, the present utility model adopts an annular slot 23 that is opened at one end of the connecting pipe 21 along the direction of the connecting pipe 21 and is adapted to it. The upper and lower inner walls of the slot 23 are provided with threads in opposite directions. When the hose 1 is inserted into the slot 23, the friction between the hose 1 and the slot 23 will generate resistance, which can increase the pre-tightening force of the connection, thereby providing a more secure fixation. The further provided threads in opposite directions can provide a self-locking force to prevent relative rotation during installation and cause detachment, thereby improving the efficiency during installation;

[0028] To further fix the hose, reinforcing holes 22 are opened on the arc surface on one side of the connecting pipe 21. At least two reinforcing holes 22 are opened, and the two reinforcing holes 22 are arranged at corresponding positions. One end of the hose 1 is fixed through a countersunk head bolt in the reinforcing holes 22;

[0029] To strengthen the strength of the hose 1, an armored pipe needs to be sleeved on the surface of the hose 1. The armored pipe is sleeved on the connecting pipe 21 and fixed by the first crimping pliers 3. At the same time, the first crimping pliers 3 clamps the connecting pipe 21 to complete the assembly;

[0030] To prevent the first crimping pliers 3 from damaging the armored pipe during fastening, an annular crimping sleeve 31 is connected to the end of the first crimping pliers 3 close to the slot 23. The crimping sleeve 31 clamps the end of the armored pipe. The crimping sleeve 31 is concentric with the first crimping pliers 3, and the distance between the arc-shaped concave surface of the crimping sleeve 31 and the concave surface of the first crimping pliers 3 is selected according to the thickness of the armored pipe to ensure the best clamping effect.

[0031] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
