Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation equipment technology, and more specifically, it relates to a spring-loaded double circular air outlet. Background Technology
[0002] Common ventilation equipment for air vents is usually installed on the indoor ceiling and connected to pre-embedded ventilation ducts in the ceiling to maintain indoor ventilation.
[0003] Currently, when installing air vents, the vent is usually connected to the pre-embedded ventilation duct. Then, the vent is inserted into the pre-drilled hole in the ceiling, and finally, rivets or expansion bolts are used to fix the vent to the ceiling, thus completing the installation of the air vent.
[0004] However, ceiling panels (such as gypsum board, mineral wool board, or aluminum composite panels) are usually made of thin or brittle materials. If the force is not properly controlled during drilling and tightening of expansion bolts, it can easily cause the panels around the mounting holes to crack, deform, or break directly, seriously affecting the overall aesthetics and installation stability of the ceiling.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spring clip type double circular air vent, which solves the problem that when installing the air vent, the panel around the mounting hole on the ceiling is easily cracked, deformed or directly damaged by rivets or expansion screws.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spring-loaded double circular air outlet, including a housing, and further comprising: A retaining ring is fixedly connected to the top of the housing to make contact with the outer wall of the ceiling. Two torsion springs are disposed on the outer wall of the housing, and the torsion springs and the outer wall of the housing are interlocked with each other; A connecting strip is fixedly connected to the side wall of the torsion spring and is used to contact the inner wall of the ceiling. When the torsion spring is in its natural state, the connecting strip and the housing abut against each other.
[0008] An adjusting block is disposed inside the housing. The adjusting block is conical in shape. A screw is fixedly connected to one side of the adjusting block. A support plate is fixedly connected inside the housing. A through hole is provided on the support plate. An internally threaded mounting ring is fixedly connected to the side wall of the through hole. The inner wall of the mounting ring is threadedly connected to the screw.
[0009] The present invention is further configured such that: two fixing blocks are fixedly connected to the outer wall of the housing, and a locking block that engages with the torsion spring is fixedly connected to the side wall of the fixing block.
[0010] The present invention is further configured such that a paddle is fixedly connected to the connecting strip.
[0011] The present invention is further configured such that: a filter screen is slidably connected inside the housing, the filter screen has an opening for inserting a screw, an mounting plate is fixedly connected to the filter screen, and an mounting groove for placing the mounting plate is provided on the inner wall of the housing.
[0012] The present invention is further configured such that when the mounting plate and the mounting groove are in contact with each other, the filter screen and the support plate are in contact with each other.
[0013] The present invention is further configured such that the filter screen is provided with several reinforcing ribs.
[0014] The present invention is further configured such that a sealing ring is fitted on the outer wall of the housing.
[0015] In summary, this utility model has the following beneficial effects: By using a retaining ring, torsion spring, and connecting strip, installation eliminates the need for rivets or expansion bolts. During installation, the connecting strip is moved to deform the torsion spring and insert it into the ceiling hole. Once the retaining ring contacts the outer wall of the ceiling, it is released, and the torsion spring returns to its original position, causing the connecting strip to press against the inner wall of the ceiling, thus firmly clamping the air vent to the ceiling. This installation method avoids the problems of ceiling panel cracking, deformation, or damage that can occur when drilling or tightening bolts. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] A type of spring-loaded double circular air vent, such as Figures 1-4 As shown, including housing 1, it also includes: The fixing ring 2 is fixedly connected to the top of the housing 1 and is used to contact the outer wall of the ceiling.
[0022] Two torsion springs 3 are set on the outer wall of the housing 1. The torsion springs 3 and the outer wall of the housing 1 are interlocked. Specifically, two fixing blocks 5 are fixedly connected to the outer wall of the housing 1. The side wall of the fixing blocks 5 is fixedly connected to the locking blocks 6 that interlock with the torsion springs 3. By setting the locking blocks 6, the torsion springs 3 and the housing 1 can be fixed to each other. At the same time, when the torsion springs 3 are damaged, they can be replaced to avoid affecting the normal use of the housing 1 in the future.
[0023] The connecting strip 4 is fixedly connected to the side wall of the torsion spring 3 and is used to contact the inner wall of the ceiling. When the torsion spring 3 is in its natural state, the connecting strip 4 and the housing 1 abut against each other, and a lever 7 is fixedly connected to the connecting strip 4, which makes it easy for the staff to move the torsion spring 3 to deform.
[0024] When installing the air vent and the ceiling together, rotating the connecting strip 4 causes the torsion spring 3 to deform. Then, the connecting strip 4 and the torsion spring 3 are placed into the hole in the ceiling. When the fixing ring 2 contacts the outer wall of the ceiling, the restriction on the connecting strip 4 is removed. At this time, the torsion spring 3 deforms and returns to its original shape, causing the connecting strip 4 to abut against the inner wall of the ceiling. At this time, the housing 1 is unable to separate from the ceiling due to the setting of the fixing ring 2 and the connecting strip 4. This achieves the effect of fixing the air vent without using rivets and expansion bolts 9, avoiding the problem of cracking, deformation or direct damage to the panels around the ceiling during the installation of the air vent.
[0025] Furthermore, the housing 1 is provided with an adjusting block 8, which is conical in shape. A screw 9 is fixedly connected to one side of the adjusting block 8. A support plate 10 is fixedly connected inside the housing 1. A through hole 11 is provided on the support plate 10. An internally threaded mounting ring 12 is fixedly connected to the side wall of the through hole 11. The inner wall of the mounting ring 12 is threadedly connected to the screw 9. When the adjusting block 8 is screwed into the mounting ring 12, the adjusting block 8 can move up and down along the inner wall of the housing 1. By using the arc-shaped adjusting block 8, the distance between the adjusting block 8 and the inner wall of the housing 1 can be changed, thereby changing the ventilation effect of the housing 1 and achieving the effect of adjusting the ventilation effect of the air outlet.
[0026] A filter screen 13 is slidably connected inside the housing 1. The filter screen 13 has an opening 14 for inserting a screw 9. An mounting plate 15 is fixedly connected to the filter screen 13. An installation groove 16 is provided on the inner wall of the housing 1 for placing the mounting plate 15. The filter screen 13 can filter dust in the ventilation duct to prevent dust from entering the room. At the same time, the mounting plate 15 makes it easy to remove the filter screen 13 for cleaning or replacement. When the mounting plate 15 and the installation groove 16 are in contact with each other, the filter screen 13 and the support plate 10 are in contact with each other, which can improve the fixing effect of the filter screen 13 after installation and improve the stability of the filter screen 13. The filter screen 13 is provided with several reinforcing ribs 17 to strengthen the structural strength of the filter screen 13.
[0027] A sealing ring 18 is fitted on the outer wall of the housing 1, which can improve the sealing effect between the housing 1 and the ventilation duct and avoid air leakage between the housing 1 and the ventilation duct.
[0028] Installation process: First, manually move the connecting strip 4 to deform the torsion spring 3, bringing it close to the housing 1. Then, insert the housing 1, along with the deformed torsion spring 3 and connecting strip 4, into the pre-drilled hole in the ceiling. Next, push the housing 1 upwards until the fixing ring 2 at the top of the housing 1 contacts the outer wall of the ceiling. Then, release the connecting strip 4. The torsion spring 3 will return to its original shape due to elastic recovery, causing the connecting strip 4 to rotate and abut against the inner wall of the ceiling. At this point, the housing 1 is clamped and fixed by the fixing ring 2 and connecting strip 4, and the installation is complete without the need for rivets or expansion bolts.
