Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust windows, in particular to a fire smoke exhaust window. Background Art

[0002] As people's awareness of fire safety and fire standards increase, smoke exhaust windows are usually installed on the top or side of buildings. On weekdays, the smoke exhaust windows are closed. When a fire occurs, the smoke exhaust windows are opened so that the indoor smoke can be discharged smoothly.

[0003] However, in the prior art, it is found that there are at least the following technical problems: when the existing smoke exhaust window is in use, it is generally opened by a telescopic column. However, when the smoke exhaust window is opened at a certain angle, it is not possible to increase the flow rate of the gas to exhaust the smoke faster, and the practicality is not high. For this reason, we provide a fire smoke exhaust window. Utility Model Content

Example

[0023] The technical solution in the embodiments of the present application is to effectively solve the technical problem that the existing smoke exhaust window is generally opened by a telescopic column when in use, but when the smoke exhaust window is opened at a certain angle, it is not possible to increase the flow rate of the gas to exhaust the smoke faster. The overall idea is as follows:

[0024] In response to the problems existing in the prior art, the present invention provides a fire smoke exhaust window, including a mounting frame 1, an outer window 12 is rotatably connected to the upper inner side of the mounting frame 1 through a hinge, the inner part of the outer window 12 is movably connected to the inner window 13, a mounting block 120 is fixedly installed on the lower surface of the outer window 12, a fixing component 3 is inserted into the top of the mounting block 120, and a telescopic column 11 is provided on the surface of the outer window 12.

[0025] In some embodiments, the surface array of the outer window 12 is provided with a slot 121, and the surface array of the inner window 13 is provided with a slot 2 130. Figures 1 to 4 As shown, at this time, the second notch 130 and the first notch 121 on the surface of the inner window 13 completely overlap, which can increase the flow speed of air and speed up the discharge of smoke.

[0026] In some embodiments, a handle 133 is fixedly connected to the middle of the bottom of the inner window 13, such as Figures 1 to 4 As shown, the inner window 13 can be easily moved.

[0027] In the specific implementation process, when the utility model is in use, the mounting frame 1 is first installed in a fixed position. At this time, one end of the insertion rod 31 is inserted into the inside of the second clamping hole 132. At this time, the notch 121 and the notch 2 130 are in a non-overlapping state, which can prevent outside rainwater from entering. When a fire occurs, a large amount of smoke will appear. The outer window 12 is connected to the inner window 13 by the telescopic column 11 to open the outer window 12, and the clamping rod 301 is pulled. The clamping rod 301 compresses the second spring 303 under the action of the second connecting rod 304 until one end of the clamping rod 301 is out of the positioning hole 35. At this time, the insertion rod 31 is no longer restricted and can be pulled upward. The insertion rod 31 compresses the first spring 303 under the action of the first connecting rod 32 The spring 34 is engaged, and it slides steadily along the direction of the first guide rod 33 until the bottom end of the insertion rod 31 is disengaged from the second clamping hole 132. The handle 133 can be pulled to slide the inner window 13 upward until the insertion rod 31 reaches the top of the first clamping hole 131. The insertion rod 31 enters the interior of the first clamping hole 131 under the action of the first spring 34, and the position of the inner window 13 can be fixed. At the same time, the clamping rod 301 enters the positioning hole 35 under the action of the second spring 303, and the insertion rod 31 can be fixed, thereby strengthening the fixation of the inner window 13. At this time, the notch 2 130 and the notch 1 121 on the surface of the inner window 13 completely overlap, which can increase the air flow speed and speed up the discharge of smoke. Example

[0028] Based on Example 1, this embodiment of the present application is a feasible technical solution for fixing components of a fire smoke exhaust window. The overall idea is as follows:

[0029] In some embodiments, the fixing assembly 3 includes an insertion rod 31, which is inserted above the interior of the mounting block 120. One side of the insertion rod 31 is fixedly connected to a first connecting rod 32, one side of the first connecting rod 32 is fixedly connected to a first spring 34, and one end of the first connecting rod 32 is slidably embedded with a first guide rod 33, such as Figures 1 to 4As shown, the locking rod 301 is pulled, and the locking rod 301 compresses the second spring 303 under the action of the second connecting rod 304 until one end of the locking rod 301 disengages from the positioning hole 35. At this time, the insertion rod 31 is no longer restricted and the insertion rod 31 can be pulled upward. The insertion rod 31 compresses the first spring 34 under the action of the first connecting rod 32 and slides steadily along the direction of the first guide rod 33 until the bottom end of the insertion rod 31 disengages from the second locking hole 132. The handle 133 can be pulled to slide the inner window 13 upward until the insertion rod 31 reaches the top of the first locking hole 131. The insertion rod 31 enters the inside of the first locking hole 131 under the action of the first spring 34, and the position of the inner window 13 can be fixed.

[0030] In some embodiments, a positioning hole 35 is formed on one side of the insertion rod 31, a clamping rod 301 is clamped on one side of the insertion rod 31, the bottom end of the clamping rod 301 is fixedly connected to the second connecting rod 304, a second spring 303 is fixedly connected to one side of the second connecting rod 304, and a second guide rod 302 is slidably embedded in the middle of the clamping rod 301. Figures 1 to 4 As shown, the locking rod 301 enters the positioning hole 35 under the action of the second spring 303, which can fix the insertion rod 31 and further strengthen the fixation of the inner window 13. At this time, the second slot 130 and the first slot 121 on the surface of the inner window 13 completely overlap, which can increase the air flow speed and accelerate the discharge of smoke.
