Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter technology, and in particular to an anti-sway device for fireproof roller shutters. Background Technology

[0002] In the field of fire-resistant roller shutter technology, fire-resistant roller shutters, as important fire-resistant partition facilities, directly affect their fire-resistant performance and service life due to their operational stability. In existing technologies, fire-resistant roller shutters often sway during lowering or retracting due to factors such as wind disturbance, uneven weight distribution, guide rail installation errors, or operational inertia. This swaying not only causes frequent collisions between the shutter and the door frame and guide rails, generating significant noise, but can also cause deformation of the shutter surface and edge wear. In severe cases, it can even affect the sealing performance between the shutter and surrounding structures, weakening the fire and smoke barrier effect and shortening the equipment's service life.

[0003] To solve the swaying problem, existing technologies mostly use fixed guide rails for limiting or a single elastic clamping structure. However, fixed guide rails are prone to jamming due to insufficient installation accuracy, while single elastic clamping structures are difficult to meet the horizontal stability requirements, have poor clamping force adjustment, and are prone to reduced anti-swaying effect due to component fatigue failure after long-term use.

[0004] Therefore, it is necessary to provide a new anti-sway device for fireproof roller shutters to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-sway device for fireproof roller shutters.

[0006] The fireproof roller shutter anti-sway device provided by this utility model includes a mounting frame plate. One side of the mounting frame plate has an opening, and a sliding plate that is elastically connected is mounted on the mounting frame plate. The opening extends from the end of the sliding plate and a V-shaped seat is fixedly mounted thereon. Two symmetrically distributed and rotatably connected abutment wheels are mounted on the V-shaped seat.

[0007] Side abutments are installed on the mounting frame plates on both sides of the opening, and each side abutment includes a sliding post. The sliding post is inserted into a side hole opened in the side wall of the opening and is slidably connected to the side hole. A rotatingly connected steel ball is embedded in the head of the sliding post, and a spring B is provided in the side hole.

[0008] Preferably, one end of the spring B is fixedly connected to the inner wall of the side hole, and the other end of the spring B is fixedly connected to the insertion end of the sliding column.

[0009] Preferably, two symmetrically distributed sliding rods are fixedly installed inside the mounting frame plate, and sleeve blocks are fixedly installed on both sides of the sliding plate, with the two sleeve blocks respectively sleeved on the two sliding rods and slidably connected to the sliding rods.

[0010] Preferably, a spring A is sleeved on the sliding rod, one end of the spring A is fixedly connected to the inner frame wall of the mounting frame plate, and the other end of the spring A is fixedly connected to the tail of the sleeve block.

[0011] Preferably, both sides of the sliding plate are provided with arc-shaped grooves, and the steel ball is inserted into the arc-shaped groove and abuts against the sliding plate.

[0012] Preferably, a fixing plate is installed on the mounting frame, and the fixing plate is fixedly connected to the mounting frame by multiple lifting rods.

[0013] Compared with related technologies, the anti-sway device for fireproof roller shutters provided by this utility model has the following beneficial effects:

[0014] Because the sliding plate is subjected to the elastic force of spring A, the abutment wheel on the V-shaped seat is firmly abutted against the fireproof roller shutter. Therefore, when the fireproof roller shutter is lowered or rolled up, the abutment wheel rotates and abuts against the fireproof roller shutter at the same time. Thus, the abutment wheel can reduce the deformation of the fireproof roller shutter in the horizontal direction, thereby reducing the swing amplitude of the fireproof roller shutter and reducing the noise generated by the collision between the fireproof roller shutter and the door frame. The two abutment wheels on the V-shaped seat can form a coordinated abutment against the fireproof roller shutter from the upper and lower sides. Especially when the roller shutter is rotated into the top box, it can enhance the stability of the curtain surface near the top box and avoid jamming caused by local deformation.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 5 This utility model provides an anti-sway device for fireproof roller shutters, which includes a mounting frame plate 1, a sliding plate 2, an abutting wheel 4, and a side abutting member 7.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 5 A fixing plate 8 is installed on the mounting frame plate 1. The fixing plate 8 is fixedly connected to the mounting frame plate 1 by multiple hanging rods 81. An opening 1a is provided on one side of the mounting frame plate 1. A sliding plate 2 with elastic connection is installed on the mounting frame plate 1. Specifically, two symmetrically distributed sliding rods 5 are fixedly installed inside the mounting frame plate 1. Sleeve blocks 21 are fixedly installed on both sides of the sliding plate 2. The two sleeve blocks 21 are respectively sleeved on the two sliding rods 5 and slidably connected to the sliding rods 5. A spring A6 is sleeved on the sliding rod 5. One end of the spring A6 is fixedly connected to the inner frame wall of the mounting frame plate 1, and the other end of the spring A6 is fixedly connected to the tail of the sleeve block 21.

[0025] The sliding plate 2 extends from the top of the plate into an opening 1a and is fixedly mounted with a V-shaped seat 3. Two symmetrically distributed and rotatably connected abutting wheels 4 are mounted on the V-shaped seat 3.

[0026] It should be noted that several sets of anti-sway devices are installed side by side at the bottom of the top box of the fireproof roller shutter. Specifically, the fixing plate 8 is fixed to the bottom of the top box of the fireproof roller shutter with screws, keeping the two abutting wheels 4 on the V-shaped seat 3 abutting against the fireproof roller shutter. Due to the elastic force of the spring A6, the sliding plate 2 is driven to make the abutting wheels 4 on the V-shaped seat 3 firmly abut against the fireproof roller shutter. Therefore, when the fireproof roller shutter is lowered or rolled up, the abutting wheels 4 rotate and abut against the fireproof roller shutter at the same time. Thus, the abutting wheels 4 can reduce the deformation of the fireproof roller shutter in the horizontal direction, thereby reducing the swing amplitude of the fireproof roller shutter and reducing the noise generated by the collision between the fireproof roller shutter and the door frame.

[0027] The V-shaped seat 3 is designed with two abutting wheels 4, which can work together to tighten the fireproof roller shutter from the top and bottom sides. Especially during the process of the roller shutter being rotated into the top box, it can enhance the stability of the curtain surface near the top box and avoid jamming caused by local deformation.

[0028] In this embodiment, a rubber ring is fitted on the abutting wheel 4 to further reduce the internal stress between the abutting wheel 4 and the fireproof roller shutter. The rubber ring also reduces noise through its buffering effect. The rubber ring of the abutting wheel 4 is made of high-strength wear-resistant material (such as polyurethane elastomer) to improve wear resistance. The abutting wheel 4 can also be designed as a detachable structure, such as being connected to the V-shaped seat 3 by bolts. When the rubber ring wears out, it can be quickly replaced without the need for a complete replacement device.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 5 Side abutments 7 are installed on the mounting frame plates 1 on both sides of the opening 1a. The side abutments 7 include sliding posts 71. The sliding posts 71 are inserted into the side holes 1b opened on the side wall of the opening 1a and are slidably connected to the side holes 1b. The head of the sliding posts 71 is fitted with a rotatably connected steel ball 72. A spring B73 is provided in the side hole 1b. One end of the spring B73 is fixedly connected to the inner wall of the side hole 1b, and the other end of the spring B73 is fixedly connected to the insertion end of the sliding posts 71. Arc-shaped grooves 2a are opened on both sides of the sliding plate 2. The steel ball 72 is inserted into the arc-shaped grooves 2a and abuts against the sliding plate 2.

[0030] It should be noted that when the sliding plate 2 is tilted to the side, the sliding column 71 in the tilting direction is subjected to a counteracting force and compresses the spring B73. Therefore, the side abutment 7 can reduce the lateral tilting amplitude of the sliding plate 2, while the steel ball 72 embedded in the sliding column 71 can improve the stability of the sliding plate 2 during longitudinal sliding.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
