Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically to a frameless panel-type smoke exhaust outlet structure. Background Technology

[0002] Smoke exhaust vents are openings located on the exterior walls or roofs of buildings, either automatically or manually, to expel smoke and heat generated during a fire. There are two main types of smoke exhaust vents: panel smoke exhaust vents and multi-leaf smoke exhaust vents. Panel smoke exhaust vents are generally used in corridors or smoke-proof vestibules, and at the smoke exhaust vents of windowless rooms. They can be suspended from the ceiling or installed on the side wall. Multi-leaf smoke exhaust vents are generally installed on the walls of stairwell vestibules and smoke exhaust shafts, and can also be installed on the side of smoke exhaust system ducts or at the end of air ducts.

[0003] Currently, panel-type smoke vents generally have an outer frame. During installation, the outer frame is simply installed into the corresponding mounting slot. However, the connecting edges of the outer frame protrude from the bottom of the wall or ceiling, affecting the overall integrity. Therefore, some users prefer smoke vent devices without an outer frame, but such devices are not currently available. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a frameless panel-type smoke exhaust outlet structure. It adopts a frameless structure, which improves the overall integrity of its installation on the ceiling.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A frameless panel-type smoke exhaust outlet structure includes a rectangular mounting groove on the ceiling for installation. A baffle plate is inserted into the rectangular mounting groove, and a reinforcing plate is fixed to the top surface of the baffle plate. A rotating shaft is movably connected to the middle of the top surface of the reinforcing plate and is movably connected to the ceiling. A control groove is formed in the middle of the top surface of the ceiling on one side of the rectangular mounting groove. Two horizontal guide rails extending to the left and right are fixed in the middle of the bottom surface of the control groove. A rack block is located between the two horizontal guide rails. One end of the rotating shaft extends into the control groove and is fixed with a transmission gear, which meshes with the rack block.

[0007] Connecting blocks are fixed to the front and rear of the top surface of the reinforcing plate, and the rotating shaft is fixed to the two connecting blocks.

[0008] The top surface of the front and rear side walls of the rectangular mounting slot is formed with a slot with an arc-shaped bottom. A self-lubricating semi-circular arc bearing block is fixed on the bottom surface of the slot. One of the slots is connected to the control groove. The corresponding end of the rotating shaft is located on the corresponding self-lubricating semi-circular arc bearing block, and its bottom surface is in close contact with the inner side wall of the corresponding self-lubricating semi-circular arc bearing block.

[0009] The ceiling is fixed with a protective cover and an upper connecting seat. The protective cover covers the control groove. The bottom surface of the side plate of the protective cover at the corresponding self-lubricating semi-circular arc bearing is formed with an upper arc groove. The upper self-lubricating semi-circular arc bearing is fixed on the inner wall of the upper arc groove. The upper wall of the corresponding part of the rotating shaft is in close contact with the inner wall of the corresponding upper self-lubricating semi-circular arc bearing.

[0010] The bottom surface of the upper connecting seat is also formed with an upper arc-shaped groove, and an upper self-lubricating semi-circular arc bearing is fixed on its inner side wall. The upper wall surface of the corresponding part of the rotating shaft is in close contact with the inner wall surface of the corresponding upper self-lubricating semi-circular arc bearing.

[0011] Connecting blocks are fixed to the front and rear of the left side wall of the control groove. One end of the reset spring is fixed to the corresponding connecting block, and the other end is fixed to the connecting block fixed on the middle outer side wall of the rack block.

[0012] The two transverse guide rails are each formed with transverse guide grooves on their opposite walls, and the rack block is formed with raised guide parts on its front and rear side walls. The raised guide parts are inserted into the corresponding transverse guide grooves and cooperate with the transverse guide grooves.

[0013] The outstanding effect of this utility model is:

[0014] Its frameless structure improves its overall integrity when installed on the ceiling, and the separate installation of the return spring and the shielding plate makes it less susceptible to oil stains and other contaminants, ensuring its normal tension and return effect.

[0022] For example, see below. Figures 1 to 7 As shown, a frameless panel-type smoke exhaust outlet structure includes a rectangular mounting groove 10 on the ceiling for installation. A baffle plate 20 is inserted into the rectangular mounting groove 10, and a reinforcing plate 21 is fixed to the top surface of the baffle plate 20. A rotating shaft 22 is movably connected to the center of the top surface of the reinforcing plate 21 and is movably connected to the ceiling. A control groove 30 is formed in the center of the top surface of the ceiling on one side of the rectangular mounting groove 10. An inner protective shell can be installed inside the control groove 30 to further improve the protection of other internally installed components. In this embodiment, the control... The inner protective shell is not installed inside the groove 30. Two horizontal guide rails 31 extending to the left and right are fixed in the middle of the bottom surface of the control groove 30. The rack block 32 is located between the two horizontal guide rails 31. One end of the rotating shaft 22 extends into the control groove 30 and is fixed with a transmission gear 23. The transmission gear 23 meshes with the rack block 32. Horizontal guide grooves are formed on the opposite walls of the two horizontal guide rails 31. Protruding guide parts 321 are formed on the front and rear side walls of the rack block 32. The protruding guide parts 321 are inserted into the corresponding horizontal guide grooves and cooperate with the horizontal guide grooves.

[0023] Furthermore, the front and rear parts of the top surface of the reinforcing plate 21 are both fixed with connecting blocks 24, and the rotating shaft 22 is fixed on the two connecting blocks 24.

[0024] Furthermore, the top surface of the front and rear side walls of the rectangular mounting groove 10 is formed with a slot with an arc-shaped bottom. A self-lubricating semi-circular arc bearing 1 is fixed on the bottom surface of the slot. One of the slots communicates with the control groove 30. The corresponding end of the rotating shaft 22 is located on the corresponding self-lubricating semi-circular arc bearing 1, and its bottom surface is in close contact with the inner side wall of the corresponding self-lubricating semi-circular arc bearing 1.

[0025] The ceiling is fixed with a protective cover 40 and an upper connecting seat 50. The protective cover 40 covers the control groove 30. The bottom surface of the side plate of the protective cover 40 at the corresponding self-lubricating semi-circular arc bearing 1 is formed with an upper arc groove. The upper self-lubricating semi-circular arc bearing is fixed on the inner wall of the upper arc groove. The upper wall of the corresponding part of the rotating shaft 22 is in close contact with the inner wall of the corresponding upper self-lubricating semi-circular arc bearing (the upper arc groove and other components at the protective cover 40 are basically the same as the structure at the upper connecting seat 50, so they are omitted from the attached drawings).

[0026] The bottom center of the upper connecting seat 50 is also formed with an upper arc-shaped groove, and an upper self-lubricating semi-circular arc bearing is fixed on its inner side wall. The upper wall of the corresponding part of the rotating shaft 22 is in close contact with the inner wall of the corresponding upper self-lubricating semi-circular arc bearing.

[0027] Furthermore, connecting blocks are fixed to the front and rear parts of the left side wall of the control groove 30. One end of the return spring 2 is fixed to the corresponding connecting block, and the other end is fixed to the connecting block fixed on the middle outer side wall of the rack block 32.

[0028] Furthermore, a transverse connecting plate 3 is fixed to the middle of the right side wall of the rectangular mounting slot 10, and one end of a steel wire rope 4 is fixed to the top surface of the middle right side of the reinforcing plate 21. The steel wire rope 4 is inserted into the through hole in the middle of the transverse connecting plate 3, and the other end of the steel wire rope 4 is installed to an externally provided remote controller for controlling the flipping of the shield 20. The remote controller is a conventional structure that can be purchased directly from the market and will not be described in detail here.

[0029] Furthermore, a left sealing strip 5 is fixed on the left side wall of the rectangular mounting slot 10, and a right sealing strip 6 is fixed on the right side wall of the rectangular mounting slot 10.

[0030] The bottom surface of the left side of the baffle plate 20 is formed with a left slot extending from front to back, and the top surface of the left sealing strip 5 is fixed with a first metal sealing piece 7, and the top surface of the first metal sealing piece 7 presses against the top surface of the left slot.

[0031] The top surface of the right side of the baffle plate 20 is formed with a right slot extending from front to back, and the bottom surface of the right sealing strip 6 is fixed with a second metal sealing piece 8, the bottom surface of the second metal sealing piece 8 pressing against the bottom surface of the right slot.

[0032] The first metal sealing sheet 7 and the second metal sealing sheet 8 can be made of stainless steel sheets. They can be used to block the gap between the left and right ends of the baffle plate 20 and the inner walls of the left and right ends of the rectangular mounting groove 10 when the baffle plate 20 is set horizontally, thereby improving the sealing effect.

[0033] In this embodiment, when in use, the return spring 2 and other components are placed in the control groove 30, so that they are separated from the rectangular mounting groove 10, thereby preventing oil and other substances in the exhaust from adhering to the return spring 2 and ensuring its normal use.

[0034] In use, the wire rope 4 is tightened by the remote controller, so that the baffle 20 is placed horizontally and covers the rectangular mounting slot 10 (the front and rear side walls of the baffle 20 are close to the front and rear inner side walls of the rectangular mounting slot 10, and the gap between them is very small and can be ignored). Through the sealing effect of the first metal sealing plate 7 and the second metal sealing plate 8, the sealing effect of the rectangular mounting slot 10 is very good at this time.

[0035] When it needs to be opened, it is turned on by the corresponding control button of the remote controller, which will release the wire rope 4. The elastic restoring force of the two return springs 2 will pull the rack block 32 to the left, so that the rotating shaft 22 rotates clockwise, thereby making the baffle 20 flip into a vertical position, realizing smoke exhaust and ventilation, which is very convenient.

[0036] When a reset is required, it can be controlled by a remote controller. The steel wire rope 4 is wound around to continuously tighten the steel wire rope 4, making the shield 20 horizontal and completing the coverage, which is very convenient.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
