Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipelines, in particular to a fire-fighting ventilation pipeline. Background Art

[0002] The purpose of setting up ventilation ducts is to allow air to circulate in the building and reduce the concentration of harmful gases in the building. In firefighting operations, ventilation ducts, as the most commonly used firefighting equipment, can discharge smoke out of the building and reduce the impact of smoke on people at the fire scene.

[0003] The utility model patent with patent authorization announcement number CN 219160520 U discloses a fire ventilation duct, wherein a plug block is fixedly connected to the bottom surface of the first fixed frame, a connecting block is fixedly installed on one side of the duct body, a plug hole is fixedly opened on the top of the connecting block, a sleeve is provided inside the connecting block, a pull rod is slidably connected inside the sleeve, a spring is sleeved on the surface of one end of the pull rod, and a clamping block is fixedly connected to one end of the pull rod.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when taking out the first fixing frame and the second fixing frame from the inside of the fixing hole, the user needs to continuously pull the pull rod through the handle to release the obstruction of the block. This results in the user being able to only operate with one hand when taking out the first fixing frame and the second fixing frame, which is difficult to operate and more labor-intensive, and is not convenient in actual use.

[0005] Therefore, it is necessary to invent a fire-fighting ventilation duct to solve the above problems. Utility Model Content

[0028] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "above," "on," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0030] Figure 2 It is a structural schematic diagram of a connection and installation mechanism 2 and a lifting mechanism 4 of a fire ventilation duct according to an embodiment of the present disclosure.

[0031] Figure 3 It is a schematic structural diagram of a filter mechanism 3 of a fire ventilation duct according to an embodiment of the present disclosure.

[0032] like Figure 1-Figure 3 As shown, the fire-fighting ventilation duct of the present disclosure may include: a ventilation transmission mechanism 1, a connecting and installing mechanism 2, a filtering mechanism 3, a lifting mechanism 4 and other components.

[0033] like Figure 1 As shown, in the present disclosure, the ventilation transmission mechanism 1 includes a pipe body 11, a flange 12 and a connecting hole 13, wherein the pipe body 11 is fixedly connected to a U-shaped connecting seat 21, and the flange 12 is fixedly sleeved on the outer side of the pipe body 11 away from one end of the U-shaped connecting seat 21, and four connecting holes 13 are provided, and the four connecting holes 13 are evenly opened at the four corners of the flange 12.

[0034] Therefore, two adjacent pipe bodies 11 can be connected through the four connecting holes 13 on the flange 12 .

[0035] like Figure 2As shown, in a preferred embodiment, the connecting and mounting mechanism 2 includes a U-shaped connecting seat 21, a locking pin 22, an inclined surface 23 and a first spring 24, wherein the locking pin 22 is slidably penetrated and arranged at the bottom of the front side of the U-shaped connecting seat 21, the inclined surface 23 is opened at the end of the locking pin 22, and the first spring 24 is sleeved and arranged on the outside of the locking pin 22 and fixedly connected between the locking pin 22 and the U-shaped connecting seat 21.

[0036] Therefore, when the activated carbon filter 33 needs to be disassembled, the locking pin 22 is manually pulled. When the locking pin 22 is pulled, the first spring 24 is stretched, and the inclined surface 23 is moved out from the inside of the locking hole 32 to release the lock on the mounting bracket 31.

[0037] like Figure 3 As shown, in the present disclosure, the filtering mechanism 3 includes a mounting frame 31, a locking hole 32 and an activated carbon filter 33, wherein the mounting frame 31 is slidably arranged on the inner side of the U-shaped connecting seat 21 along the vertical direction, the locking hole 32 is opened on the front side of the mounting frame 31, and the activated carbon filter 33 is fixedly arranged on the inner side of the mounting frame 31.

[0038] In this way, the activated carbon filter 33 can filter the airflow passing through the inside of the pipe body 11, and thus remove foreign matter in the airflow. In addition, when the mounting bracket 31 is inserted into the inner side of the U-shaped connecting seat 21, the mounting bracket 31 presses down the push block 44, and then the push block 44 compresses the second spring 42 through the lifting column 43. Subsequently, the mounting bracket 31 squeezes the inclined surface 23 at the end of the locking pin 22, and then the locking pin 22 stretches the first spring 24. When the subsequent mounting bracket 31 is installed in place, the locking pin 22 is inserted into the inner side of the locking hole 32 to lock the mounting bracket 31.

[0039] like Figure 2 As shown, in a preferred embodiment, the lifting mechanism 4 includes a mounting groove 41, a second spring 42, a lifting column 43 and a push block 44, wherein the mounting groove 41 is opened at the top of the side of the U-shaped connecting seat 21, the second spring 42 is fixedly connected to the bottom of the inner side of the mounting groove 41, the lifting column 43 is slidably arranged on the inner side of the mounting groove 41 along the vertical direction and is fixedly connected to the second spring 42, and the push block 44 is fixedly arranged at the top of the lifting column 43.

[0040] Therefore, after the blocking of the locking pin 22 on the locking hole 32 is released, the compressed second spring 42 drives the lifting column 43 to move upward. During the upward movement of the lifting column 43, the mounting frame 31 is pushed, and then the mounting frame 31 drives the activated carbon filter 33 to move upward. Then, the locking pin 22 is released, and the mounting frame 31 is directly pulled upward to complete the removal of the activated carbon filter 33.
