Description

Technical Field

[0001] This application relates to the field of roller shutter door accessories technology, and in particular to a sealing structure for roller shutter doors. Background Technology

[0002] Roller shutters, as a common type of door and window, are widely used in commercial buildings, industrial plants, garages, and other places, offering advantages such as small footprint, ease of operation, and good security. However, in actual use, the sealing performance of roller shutters has always been one of the key factors affecting their effectiveness. Currently, most roller shutters on the market have a sealing structure at the bottom to reduce the gap between the door and the ground, thus achieving sealing effects such as dustproofing, windproofing, and waterproofing. However, existing roller shutter sealing structures have many shortcomings: some sealing structures use a fixed connection method, making it difficult to disassemble and replace when the seals are worn or damaged, resulting in high maintenance costs; some sealing structures have poor locking stability, and are prone to loosening or even falling off during repeated raising and lowering of the roller shutter, affecting the sealing effect; in addition, the existing seals have poor cushioning performance, and when the door descends and contacts the ground, it is easy to generate a large impact force, which not only shortens the service life of the seals but may also damage the overall structure of the roller shutter.

Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0016] like Figure 1-3 As shown, this utility model discloses a technical solution for a sealing structure for a roller shutter door, which is set along the length of the roller shutter door and includes a clamp 1. The clamp 1 has an H-shaped structure, with an upper part being a locking part 2 and a lower part being an mounting part 3. In this embodiment, the clamp 1 is made of high-strength aluminum alloy, which can meet the requirements of the clamp structure stability and durability during the repeated lifting and lowering of the roller shutter door. At the same time, it is easy to process into an H-shaped structure and has a moderate cost, making it suitable for mass production. In addition, cold-rolled steel plate material can also be selected according to the strength requirements of the actual use scenario. Specifically, the engaging part 2 is provided with a first engaging groove 6, the width of which gradually decreases from top to bottom. A notch 7 is provided at the center of the top of the first engaging groove 6, and symmetrical limiting clamps 8 are integrally provided on both sides of the notch 7. Multiple fixing holes 9 are provided on the limiting clamps 8 along their length direction. The sealing structure can be fixedly connected to the bottom of the roller shutter door by bolts passing through the fixing holes 9. A first buffer pad 10 is bonded to the inner side of the limiting clamp 8, which can reduce the collision and wear between the roller shutter door and the clamp 1 on the one hand, and enhance the sealing between the roller shutter door and the clamp 1 on the other hand. In this embodiment, the first buffer pad 10 is made of rubber. Specifically, the mounting part 3 is provided with a second mounting groove 11 with the opening facing downward, and the sealing assembly is installed in the second mounting groove 11; the sealing assembly includes a fixing member 4 and a sealing member 5. The top of the sealing member 5 is provided with a first T-shaped protrusion 15, and the bottom of the fixing member 4 is provided with a first T-shaped slot 12 that cooperates with the first T-shaped protrusion 15. The sealing member 5 is inserted into the first T-shaped slot 12 through the first T-shaped protrusion 15 to achieve a detachable connection with the fixing member 4. Specifically, the two side walls of the fastener 4 are symmetrically provided with second T-shaped slots 13, and second T-shaped protrusions 19 are inserted into the second T-shaped slots 13. The side walls of the second T-shaped protrusions 19 abut against the inner wall of the second mounting groove 11, further enhancing the stability of the fastener 4 installation. The top of the fastener 4 is fixedly installed in the middle of the clamp 1 by locking bolts 14 to ensure that the fastener 4 will not be displaced during use. In this embodiment, the fastener 4 is made of high-strength aluminum alloy, and the second T-shaped protrusions 19 can be made of rigid PVC (polyvinyl chloride), which has a certain strength and hardness and can fit tightly with the inner walls of the second T-shaped slots 13 and the second mounting groove 11 to play a stable support role; or nylon material can be selected, which has good mechanical strength and wear resistance, and a longer service life, suitable for roller shutter door scenarios with long-term high-frequency use. Specifically, the bottom of the seal 5 has an arc-shaped structure, and integrated sealing baffles 18 are provided on both the front and rear edges of the bottom, extending towards the center, which can better fit with the ground and improve the sealing effect. The lower part of the seal 5 has a through-hole group along its length, including two first through holes 16 at the front and rear of the top and a second through hole 17 in the middle of the bottom. These through holes can play a certain role in buffering and deformation when the seal 5 contacts the ground, enhancing the sealing performance and service life. In this embodiment, the seal 5 is made of ethylene propylene diene monomer (EPDM) rubber, which has excellent weather resistance, aging resistance and elasticity, can adapt to different temperature environments, and has good sealing performance. When in contact with the ground, it can form an effective seal, and its good toughness can work with the through-hole group to achieve buffer deformation. Alternatively, neoprene rubber can be used, which has good wear resistance and oil resistance, and is suitable for scenarios with high requirements for the durability of the seal. Specifically, a second buffer pad 20 is bonded to the bottom of the clamp 1, which can reduce the impact force between the clamp 1 and the ground during the descent of the roller shutter door. In this embodiment, the second buffer pad 20 is made of nitrile rubber or silicone.

[0017] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
